Description

The two-way detent mechanism of a kind of door lock handle

Technical field

The present invention relates to the two-way detent mechanism of a kind of door lock handle; It is particularly to two reseting plates of assembling on the inner structure of a locking face, with spring two reseting plates is connected, and two reseting plates form an enclosed construction with spring; Locating piece to being assemblied on door lock and the handle plays position-limiting action; Locating piece links to each other with handle and can drive mutually with handle, thereby utilizes the back stretch of spring to promote the handle reset function, and handle is played positioning action.

Background technology

Door lock kind in the market is varied, and the location structure kind of handle is also more and more, and most location structure all is an architectural feature of selecting spring for use, for example whirlpool spring and extension spring; Wherein the whirlpool spring is generally annular, utilizes the characteristic of the entad torsion of whirlpool spring to realize the handle location; Extension spring is generally strip, utilizes the restoring force of extension spring, realizes positioning function; In order to realize the two-way reset balance and the positioning function of handle; The number of applications of extension spring generally needs two in the door lock handle location structure; Two extension springs are drawn respectively, thereby reach the function of the two-way location of door lock handle, how simplify number of parts; Simplify product structure, become a new technical research direction.

Summary of the invention

Characteristics such as the purpose of this invention is to provide the two-way detent mechanism of a kind of new door lock handle, the reversible handle detent mechanism before following is compared, and has and has simplified part, and the saving cost reduces volume, and is easy to assembly, and cost of production is low.

In order to achieve the above object, technical scheme of the present invention is following:

The two-way detent mechanism of a kind of door lock handle comprises: handle assembly 1, locking face 2, reset assembly 3; It is characterized in that reference column 21, circular hole 22 are arranged on the locking face 2, on the handle assembly 1 square structure is arranged, handle assembly 1 is assemblied in the circular hole 22 of locking face 2 and can be around circular hole 22 rotation; One end of reset assembly 3 is assemblied on the reference column 21 of locking face 2, and the other end is installed on the square structure of handle assembly 1, and reset assembly 3 is driven by handle assembly 1.

Said reset assembly 3 is made up of first reseting plate 31, second reseting plate 32, extension spring 33; First circular hole 311, first end points 312 are arranged on first reseting plate 31; There are second circular hole 321, second end points, 322, the first circular holes 311 and second circular hole 321 to be sleeved on successively on the reference column 21 on second reseting plate 32; One end of extension spring 33 is assemblied on first end points 312, and the other end of extension spring 33 is assemblied on second end points 322; First reseting plate 31 and second reseting plate 32 lay respectively at the opposite side of the square structure of handle assembly 1, and handle assembly 1 is formed position limiting structure.

Said handle assembly 1 is made up of handle 11 and locating piece 12, has a clipping block on the handle 11 at least, has a groove on the locating piece 12 at least, and the groove tabling on clipping block on the handle 11 and the locating piece 12 is fixed.

Square structure on the said handle assembly (1) also can be a rhombus.

Description of drawings

Fig. 1 is an explosive view of the present invention;

Fig. 2 concerns sketch map for reset condition part of the present invention;

Fig. 3 concerns sketch map for part under the figure motion state of the present invention;

Fig. 4 finishes sketch map for athletic performance of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:

Like Fig. 1; Shown in Figure 2; On the reference column 21 of locking face 2 inside, assemble two reseting plates up and down successively: first reseting plate 31 and second reseting plate 32, connect with the other end of extension spring 33 two reseting plates, two reseting plates form an enclosed construction with extension spring 33; Thereby foursquare two opposite side that two reseting plates have clamped locating piece 12 play position-limiting action to locating piece 12; Locating piece 12 links to each other with handle 11 and can drive mutually with handle 11, thereby utilizes the back stretch of extension spring 33 to promote handle 11 positioning functions, and handle 11 is played positioning action.

Like Fig. 2, shown in Figure 3, when receiving the external force effect, handle assembly 1 is rotated counterclockwise when action; First reseting plate 31 and second reseting plate 32 generations laterally the motive force of square structure on the handle assembly 1 to being assemblied in both sides, be assemblied in two extension springs 33 on the reseting plate and receive pulling force this moment, produces deformation; Make two reseting plates clamp handle assembly 1 more; When handle 11 rotated 45 °, the diagonal angle of square structure contacted with two reseting plates, and it is maximum that the deformation of extension spring 33 reaches; As shown in Figure 4, handle 11 continues rotation, stops when reaching 90 °, and two other opposite side of square structure is clamped by two reseting plates and is positioned again at this moment.

Obviously; Do when turning clockwise when handle assembly 1 receives external force, the square structure on the handle assembly 1 is to the motive force that first reseting plate 31 that is assemblied in both sides and second reseting plate 32 produce laterally, is assemblied in two extension springs 33 on the reseting plate this moment and receives pulling force and produce deformation; Make two reseting plates clamp handle assembly 1 more; When handle 11 rotated 45 °, the diagonal angle of square structure contacted with two reseting plates, and it is maximum that the deformation of extension spring 33 reaches; As shown in Figure 4, handle 11 continues rotation, stops when reaching 90 °, and two other opposite side of square structure is clamped by two reseting plates and is positioned again at this moment.

To sum up, the present invention is the two-way detent mechanism of a kind of door lock handle, and no matter handle is rotated counterclockwise or turns clockwise when the handle rotation puts in place, and this mechanism can locate handle with respect to locking face.
