Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is a perspective view of a solar panel fixing member according to an embodiment of the present invention, and FIG. 7 is an exploded perspective view of a solar panel fixing member according to an embodiment of the present invention. 5A to 5D are partial cross-sectional views illustrating a solar panel fixing process using a solar panel fixing member according to an embodiment of the present invention.

The fixing member of this embodiment has a first inclined portion 410a and a second inclined portion 410b, a third inclined portion 410c, a body portion 410m, a catching portion 410d, And is configured to have a circular cross-sectional shape as a preferred example.

The first inclined portion 410a has a tilted state of a vertically downward light based on a cross section.

The second inclined portion 410b is integrally connected to the lower end of the first inclined portion 410a and has an inclined upper surface with respect to a cross section.

The third inclined portion 410c is integrally connected to the lower end of the second inclined portion 410b and has a sloping state of a downward slope based on a cross section.

The body portion 410m is integrally connected to the lower end of the third inclined portion 410c, and is formed in a shape similar to a cylinder, for example.

The latching part 410d is formed integrally with the lower end of the body part 410m and has a latching element that can be locked by a predetermined object. Preferably, the latching portion 410d includes a latching element that provides a latching function of restricting movement in at least a vertical direction. In the case of this embodiment, the latching element is formed in the form of a latching jaw having a substantially T-shaped cross section.

The fixing member of this embodiment is formed of a material capable of being elastically deformed (e.g., a synthetic resin, a soft metal).

In addition, the fixing member of the present embodiment is provided with at least the first inclined portion 410a and the second inclined portion 410b integrally connected to the first inclined portion 410a so as to have an expanded state and a reduced state by the elastic deformation, ) Is formed.

3 and 4, the latching part 410d is engaged and fixed to one element requiring a fixed connection, and the first inclined part 410a is fixed to the other element, (Or press-fitting) an inclined portion extending from the third inclined portion 410c to the third inclined portion 410c using elastic deformation.

As a more preferable example, the fixing member of the present embodiment is configured such that the inclined portions 410a to 410c extending from the first inclined portion 410a to the third inclined portion 410c are expanded and contracted by elastic deformation It is possible to further provide a structure for realizing more easily and firmly.

In order to achieve this, in the fixing member of the present embodiment, a hollow portion 410h connected to the cut-off portion 410f is formed along the longitudinal direction within the body portion 410m and the third inclined portion 410c, An elongated hole 410i is formed on one side of the main body 410m and a pressing force is applied to the upper side of the hollow portion 410h by an elastic force of a lower spring 416, The first adjustment piece 414 is vertically movable by the first adjustment pin 414c protruded through the first adjustment pin 414c. The spring 416 is positioned between the lower end of the first adjusting piece 414 and the upper end of the second adjusting piece 418 to be described later to provide a lubrication force to both sides.

With this configuration, the fixing member of the present embodiment is configured such that, when the first adjustment pin 414c is biased by the spring 416 to provide a pressing force upward, 414a provide a pressing force outwardly from the inside of the cutout 410f of the slopes 410a-c so that the slopes 410a-c are expanded by elastic deformation, When the pin 414c is pushed downward and the first adjusting piece 414 is moved downward, the tip end portion 414a of the first adjusting piece 414 is moved down together so that the inclined portions 410a to c are resilient The deformation is restored to a reduced state.

For example, as described above, when the engaging portion 410d is engaged with one element and the inclined portions 410a to 410c are fixed to the other element by elastic deformation The first adjusting pin 414c is pushed downward so that the penetration (or press-fitting) of the first adjusting pin 414c is facilitated when the slanting portions 410a-c are pierced (or press-fitted) 5C). When completing the fixed engagement after the insertion (or press-fitting) is completed, the first adjustment pin 414c is released from the depressed state, 1 adjustment piece 414 can be moved upward so that the inclined portions 410a to 410c can be made to be in an expanded state (state of FIG. 5D).

Meanwhile, if the one-side element and the other side element are to be separated for repairing or replacing, it is possible to carry out the separating operation through the reverse process.

Through such operations, the fixing member of the present embodiment makes it possible to perform fixing or separation work more conveniently and firmly than when using only the elastic deformation of the slopes 410a to 410c.

As a more preferable example, the fixing member of the present embodiment may further include a structure for more easily and securely fastening the engagement portion 410d.

For this purpose, the fixing member of the present embodiment has a hollow portion 410h along the longitudinal direction inside the body portion 410m and the engaging portion 410d, and a long hole (not shown) is formed on one side of the body portion 410m And a second adjusting pin 418c protruding outward through the slot 410i is provided on the lower side of the hollow portion 410h by a spring 416. The second adjusting pin 418c The second adjusting piece 418 is movable up and down.

With this configuration, the fixing member of the present embodiment is configured such that, when the second adjusting pin 418c is urged downward by the spring 416 and is pressed downward, through the lowermost end of the hollow portion 410h, The conical tip portion 418a of the first adjustment pin 418 is protruded to the outside by a predetermined length and when the user pushes the second adjustment pin 418c upward to move the second adjustment piece 418 upward The tip end portions 418a of the second adjustment piece 418 are moved upward together to form a state in which they are not projected.

For example, as described above, when the engaging portion 410d is engaged and fixed in the slot portion 324b of the channel beam 324 in which a slot having a substantially T-shaped cross-section is formed along the longitudinal direction, The second adjusting pin 418c is pushed up to the fixed position where the second adjusting piece 418 is moved upward (state of FIG. 5A) to slide the fixing member in the slot (in FIG. 5A, The pushing state of the second adjusting pin 418c is released so that the tip portion 418a of the second adjusting piece 418 is moved in the direction of the vertical direction of the channel beam 324 And inserted into the through hole 324a formed in the lower end surface to form a solid mounting state (state of FIG. 5B).

On the other hand, if the fixing member of the present embodiment has the above-described basic structure and the first adjusting piece 414 and / or the second adjusting piece 418, the assembling structure is advantageous in terms of the convenience of the assembling process and robustness of the product The present invention is not limited to any one of the assembled structures. For example, the exploded perspective view of FIG. 7 shows the fixing member 410 as being cut into both right and left sides around the long hole 410i, but it is not necessarily limited to having such a cut structure, . Also, in the coupling of the respective disassembled elements, both sides may be mechanically engaged (for example, bolted connection, recessed-recessed press-fit type coupling, outer peripheral coupling ring coupling or the like) or physical / chemical coupling ) Can be applied.

In addition, although the fixing member illustrated in the drawings is exemplified as the inclines 410a to 410c being cut into four parts, the fixing members may be cut into two or other numbers.
