Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a row connecting bolt for connecting a plurality of cabinets in parallel.

[0002]

2. Description of the Related Art Conventionally, when a large number of cabinets are arranged and installed, it is common to connect the cabinets in parallel in a row and tighten frames of adjacent cabinets with connecting bolts or the like. .

[0003]

However, in such a cabinet connection, it is necessary to remove the cabinet door to perform the work, or if the door is not removed, two workers are required. For example, there is a problem that labor is required, work is inferior, workability is inferior, and time and cost are required.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connecting bolt for a train lantern which can connect a frame of a cabinet alone by using a unique washer in order to solve such a conventional problem. It is in.

[0005]

In order to achieve the above object, a connecting bolt for a train wheel according to the present invention comprises a hexagonal bolt having a substantially hexagonal head and a threaded thread portion, and A substantially hexagonal nut screwed to the threaded portion of the bolt, wherein at least one bent claw that is interposed in the threaded portion of the hexagonal bolt and protrudes in the front-rear direction is provided on the edge. It has a washer.

In the connecting bolt for a train board according to the present invention, a keyhole-shaped mounting hole for connecting a plurality of cabinets is provided in a cabinet frame, and the temporarily assembled hexagonal bolt and nut set is mounted on the mounting frame. It is characterized by being mounted in a hole and attached.

Further, in the connecting bolt for a row board according to the present invention, the washer is formed in a substantially hexagonal shape from a metal plate material, and the pair of claws are bent substantially perpendicularly to one side from the opposing edges of the hexagon. In addition to the above, another claw is provided by being bent substantially at a right angle from the top between the opposed edges to the other side.

[0008]

According to the connecting bolt for a train wheel of the present invention, the claw on one side of the substantially hexagonal washer is engaged with the edge of the mounting hole, and the claw on the other side is fixed. The lock on the side of the nut prevents the washer from rotating and the nut is fixed without rotating, so that the cabinet frame can be tightened from one side, allowing the operator to remove the door without having to remove the door. Work can be performed, and workability at the time of cabinet installation is improved.

Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a connecting bolt for a train of the present invention in a drawing. FIG. 1 is an internal front view of a cabinet connected by using a connecting bolt for a train of the present invention. FIG. 2 is an exploded perspective view showing a connecting bolt for a train board according to the present invention;
FIG. 3 is a rear view when the connecting bolt for a train wheel of the present invention is mounted.
FIG. 4 is a side view of the connecting bolt for a train wheel according to the present invention.

As shown in FIG. 1, a connecting bolt 10 for a side panel according to the present invention is used for connecting and installing a plurality of, for example, two adjacent cabinets 1, 1 adjacent to the cabinets 1, 1. The fitting frame 2 is used so as to be connected at the mounting hole 3 by a connecting bolt 10 for a train. Each cabinet 1 has a door 5 that can be opened and closed, and a plurality of mounting holes 3 for connection are provided in the frames 2 on both sides at intervals in the vertical direction. Are connected by a connecting bolt 10 for a train. As shown in FIG. 3, the mounting hole 3 has a keyhole shape, and has a large mounting hole 3a provided in a size that allows the hexagonal nut 14 of the connecting bolt 10 for a train to be inserted. It is formed from a mounting small hole 3b provided continuously below the large hole 3a.

As clearly shown in FIGS. 2 and 4, a connecting bolt 10 for a train wheel of the present invention has a hexagonal bolt 11 having a substantially hexagonal head 12 and a threaded threaded portion 13.
And a substantially hexagonal nut 14 having a screw hole 15 at the center, which is screwed to the screw portion 13 of the hexagon bolt 11, and a hole 17 interposed in the screw portion 13 of the hexagon bolt 11 at the center. And a substantially hexagonal washer 16 which is provided on the edge thereof and which is bent in the front-rear direction.

As shown in FIGS. 2 to 4, the washer 16 is formed in a substantially hexagonal shape from a suitable metal plate, and has a hole 17 for a screw portion 13 of the hexagonal bolt 11 in the center. Further, on opposite sides, claws 18, 18 are provided which are bent substantially at right angles toward one side, and another claw 19 is provided on one side or edge of the hexagon on the other side. Is bent substantially at a right angle. Although two claws 18 are provided in the illustrated embodiment,
It should be understood that the number and shape are not particularly limited, and any one may be used as long as it effectively acts as a detent for the hexagonal nut 14. .

In order to connect the cabinet 1 using the connecting bolt 10 for a train board according to the present invention thus constructed, first, as shown in FIG.
3, the washer 16 is mounted through the hole 17 of the washer 16, and then a hexagonal nut 14 is lightly screwed into the screw portion 13 of the hexagonal bolt 11, that is, screw-engaged to temporarily mount the hexagonal bolt and nut. Are formed in advance, and a connecting bolt 10 for a row board is prepared as shown in the figure.

Next, cabinets 1 and 1 to be installed
Are attached to each other in the adjacent frames 2 and 2 so that the mounting holes 3 and 3 are aligned with each other.
A set of hexagonal bolts and nuts, that is, a connecting bolt 10 for a train board according to the present invention shown in FIG. 4 through the fitting large holes 3a, 3a of the keyhole-shaped mounting holes 3, 3 of the frames 2, 2, The nut 14 side is inserted into the mounting hole 3 a of the mounting hole 3 in the axial direction of the screw portion 13, and the hexagonal bolt 1 is inserted.
The screw portion 13 between the head 12 and the washer 16 is located at the mounting hole 3 of the frame 2. Next, the row board connecting bolt 10 is moved in a direction perpendicular to the axial direction of the screw portion 13 so that the screw portion 13 is fitted into the mounting hole 3 b of the mounting hole 3 of the frame 2. The screw portion 13 between the head 12 and the washer 16 of the hexagonal bolt 11 is fitted into the small mounting hole 3 b of the mounting hole 3.

When the head 12 of the hex bolt 11 is tightened with a tool such as a wrench or a spanner, the nut 14 is securely clamped between the claws 18 of the washer 16 as shown in FIG. Then, the pawls 18 are held by the pawls 18 and 18 so as not to rotate, and another pawl 19 on the opposite side of the washer 16 is engaged with the edge of the mounting hole 3 of the frame 2 so that the washer 16 is fixed to the frame 2. Since the nut 14 is firmly held, the nut 14 is also fixedly held to the frame 2 so that the hexagon bolt 11 can be suitably tightened, and the cabinets 1 and 1 can be firmly connected and installed. Further, such a set of hexagonal bolts and nuts of the connecting bolt 10 for the row board can be easily handled by one worker without any difficulty, and the door 5 of the cabinet 1 does not need to be detached at all, and is short. The connection and installation work of the cabinet 1 can be efficiently performed in a short time.

[0017]
