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 in which angle adjustment is possible.

Generally, brackets are used to support shafts, levers, shelves, lighting devices, antenna devices, etc., by protruding from structures such as machine bodies, walls, and pillars. Brackets for such applications are required to be able to convert and adjust the angle in order to appropriately correspond to the placement angle between the structure and the object or to increase the use efficiency of the lighting device and the antenna device, in which directionality is particularly important among the objects.

For example, Utility Model Registration Nos. 20-0282819 and 1989-0002401 disclose brackets in which angle conversion is possible by a hinge structure. The bracket is composed of a fixed body formed with a plurality of mounting holes, a rotating part hinged to the fixed body having a fixing hole, and a fixing pin penetrating the mounting hole and the fixing hole. Since the fixing pin is selectively mounted among a plurality of installation holes, it is possible to change the angle of the rotating part.

According to the above prior art, in order to adjust the angle of the rotating part relative to the fixing body, it is necessary to match the fixing hole with one of the installation hole selected from a plurality of and to pass the fixing pin through the matching hole. Therefore, the work for the angle conversion and fixing is very cumbersome, and the width of the angle conversion is narrow, it is impossible to adjust to various angles.

It is an object of the present invention to provide a bracket that can be easily and variously converted and adjusted angle. In the present invention, two elements that can be rotated in different directions from the fixed base and are elastically contacted to achieve variety and ease of bracket angle conversion and adjustment.

The intermediate block 20 has the support 30 and the base 10 in contact with the protrusions 31 of the support 30 and the protrusions 11 of the base 10 on the upper and lower sides thereof, respectively. ) Is placed between.

The coupling member 40 includes a shaft 41, and the shaft 41 has these elements 30, 20 with the support 30, the intermediate block 20, and the base 10 arranged vertically. 10 are sequentially penetrated and mutually contacted.

According to FIG. 2, the protrusion 11 of the base 10 has a round shape, and a long hole 13 in a round direction is formed on an upper surface of the protrusion 11. Preferably, a plurality of irregularities 14 are formed on the surface of the protrusion 11. Similarly, the protrusions 31 of the support 30 are rounded, and a long hole 33 in a round direction is formed on an upper surface of the protrusions 31, and a plurality of unevennesses 34 are preferably formed on the surface of the protrusions 31. Is formed.

The intermediate block 20 has a through hole 25 formed at the center thereof, and has round recesses 21 and 23 in directions crossing each other (see FIG. 3 in parallel). Accordingly, the intermediate block 20 can be rotated in one direction with respect to the base 10, and the support 30 can be rotated in a direction intersecting with the rotation direction of the intermediate block 20. Preferably, a plurality of recesses and protrusions 22 and 24 are formed on the surface of each recess 21 and 23. The protruding portion 11 of the base 10 is interviewed so as to be caught by the unevenness 14 and 22 in one concave portion 21 of the intermediate block 20, and the support 30 in the other concave portion 23. Protrusions 31 are interviewed so as to be caught by the unevenness 24 and 34.

The coupling member 40 has a shaft 41 which sequentially passes through the long hole 33 of the support 30, the through hole 25 of the middle block 20, and the long hole 13 of the base 10. A spring 43 is provided on the outer diameter of the shaft 41 above the earth 30. Preferably, the shaft 41 is a bolt and includes a nut member 42 fastened to the bolt end. The spring 43 presses the state in which the support 30, the intermediate block 20, and the base 10 are in contact with each other with elastic force.

In order to reduce wear due to friction with the bolt shaft 41 at the time of rotation, the coupling member 40 is preferably formed in each of the projections 11, 10 of the base 10 and the support 30 with the shaft hole 46 is formed. And axial fixtures 44 and 45 provided on the inner surfaces 12 and 32 of 31, respectively.

At this time, the intermediate block 20 has recesses 21 and 23 in the direction crossing each other, so that the intermediate block 20 and the support 30 are interviewed with each recess 21 and 23. ) Can be rotated in a direction crossing each other.

Referring to FIG. 3, the shaft 41 is pivotable along the long hole 13 of the protrusion 11 of the base 10. In addition, the shaft 41 penetrates the through hole 25 of the intermediate block 20 and the long hole 33 of the support 30 disposed in a perpendicular relationship with the long hole 13 of the base 10. . Therefore, the intermediate block 20 can be turned along with the support 30 along the long hole 13 of the base part 10 protrusion.

Referring to FIG. 4, the support 30 is rotatable, regardless of the turning of the intermediate block 20, within the range of the long holes 33 through which the shaft 41 passes. The rotation direction at this time is perpendicular to the turning direction of the intermediate block 20.

3 and 4, the rotation of the intermediate block 20 and the support 30 is pushed with a force greater than the pressure of the spring 43, after the rotation of the pressure of the spring 43 and the corresponding unevenness 14 , 22, 24, 34 are fixed. However, when the support object is particularly heavy or unnecessary contact with the support object is expected, it may be more firmly fixed by tightening the bolt shaft 41 after the rotation adjustment.

As described above, the present invention has an intermediate block and a support that can rotate in a direction crossing each other from the base. In addition, the rotation of each part can be pushed with a force slightly higher than the pressure of the elastic body. Therefore, there is an effect that the angle conversion and adjustment can be made easily and variously.
