Description

Bracket capable adjusting angle}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket for supporting various mechanical parts, devices, and the like, and more particularly, to a bracket for easy angle adjustment and fixing.

In general, the bracket is fixed to a structure such as a machine body, a wall, a pillar, etc. and is used to support a shaft, a shelf, a lighting device, or an antenna device. Brackets for such use are required to be able to change and adjust the angle in order to properly correspond to the placement angle between the structure and the object, or to increase the use efficiency of the lighting device or the antenna device in which the direction is particularly important among the objects.

For example, Utility Model Registration No. 242503 discloses an antenna bracket capable of angle adjustment. In more detail, the bracket includes an antenna fixing part, a base, two clamps disposed between the fixing part and the base and connected to each other by pins, a shaft pin connecting the fixing part and the first clamp, and the base and the second clamp, respectively; It includes a locker.

In this structure, the antenna bracket is released by rotating the clamp or the antenna fixing part to release the locker to change the angle, and then locks the locker again to test the orientation. It is used as a locking method.

According to the conventional bracket described above, it is possible to adjust the angle by rotating the clamp or antenna fixing. However, there is a problem that is very inconvenient to use because the rocker must be repeatedly released to lock the angle to adjust the angle. In addition, the applied rocker device is easy to be released by inadvertent contact, and there is a problem in that the clamp or antenna fixing part becomes free and rotates by its own weight, thereby deviating greatly from the optimally determined direction. On the other hand, the above-described conventional bracket has a problem that it is troublesome to disassemble and assemble because of the large number of parts.

Accordingly, an object of the present invention is to provide a bracket that is easy to convert, adjust and fix the angle. In addition, it is an object of the present invention to provide a bracket that does not significantly deviate from an optimally determined direction even by inadvertent contact or pressure, for example.

The bracket of the present invention is:

A base having a first receiving end raised from a plate fixed to the structure and having a first receiving groove formed inside the first receiving end; A switching member integrally formed with a first insertion end fitted into the first accommodation groove and a second accommodation end formed in a direction crossing the first insertion end and having a second accommodation groove formed therein; An object support having a second insertion end fitted into the second accommodation groove; And a coupling member including a pivot shaft installed through the receiving end and the insertion end of each couple, and an elastic body disposed in the outer diameter of the pivot shaft inside the insertion end to press the insertion end in close contact with the receiving end. .

Preferably, the receiving groove and the insertion end is characterized in that the friction contact by the projection.

In the bracket structure according to the present invention, the switching member and the supporting portion are pivotable in the direction crossing each other. In addition, the rotation of each part is possible with a force slightly stronger than the friction force between the pressure and the projection of the elastic body, a separate operation for fixing after the rotation is not required. Therefore, the angle can be easily converted, adjusted and fixed.

These features and operations of the present invention will become more apparent from the following description of the embodiments described with reference to FIGS. 1 to 5.

The switching member 30 is formed in a direction intersecting the cylindrical first insertion end 31 and the first insertion end 31 fitted into the first receiving groove 23 of the base 20, and is formed inside the first insertion end 31. The second accommodating end 32 in which the second accommodating groove 33 is formed is integrally formed. Radial protrusions 34, corresponding to the protrusions 25 of the first accommodation grooves 23 of the base 20, are formed at the front end portions of the first insertion ends 31, centering on the central hole 35. . In addition, a radial protrusion 36 is formed on the inner surface of the second accommodation groove 33 of the second accommodation end 32 about the center hole 37.

The support portion 40 has a plate 41 to which the object is fixed, and a second insertion end 42 which is integrally formed with the plate 41 and fitted into the second receiving groove 33 of the switching member 30. . On the front end of the second insertion end 42, a radial protrusion 43 corresponding to the protrusion 36 of the second receiving groove 33 of the switching member 30 is formed around the central hole 44. do.

The coupling member 50 includes a pivot shaft 51 installed through the receiving end of each couple and the central holes 24-35 and 37-44 of the insertion ends 22-31 and 32-42, and each insertion end. It includes an elastic body 53 is disposed at the outer diameter of the pivot shaft 51 in the interior of the 31, 42 to press the insertion end (31, 42) in close contact with the receiving end (22, 32). The pivot shaft 51 is a bolt, reference numeral 52 is a nut member fixed to the end of the pivot shaft 51, and the elastic body 53 is an elastic spring.

Referring to FIG. 3, the coupling member 50 is fastened in a state in which the receiving end and the insertion end 22-31 and 32-42 of each couple are combined. The pivot shaft 51 penetrates the receiving end of each couple and the central holes 24-35 and 37-44 of the insertion ends 22-31 and 32-42, and the ends thereof are inside the insertion ends 31 and 42. Located in The nut member 52 is fixed to the end of the pivot shaft 51, and at this time, the elastic body 53, which is compressed at both ends between the nut member 52 and the inner walls of the insertion ends 31 and 42, is pivot shaft 51. Be placed at the outer diameter of

By the pressing force of the elastic body 53, the insertion end (31, 42) is in close contact with the inner surface of the receiving groove (23, 33) in the state fitted to the receiving end (23, 33), in this state The projections 25 and 36 of the 23 and 33 and the projections 34 and 43 of the insertion ends 31 and 42 are elastically engaged. The close pressing force of the elastic body 53 can be adjusted by tightening / unscrewing the bolt of the pivot shaft 51.
