The present invention relates to a shelf, and more particularly to a bracket for a shelf for use in storage and hanging articles.

Generally, the racks are installed in the bathroom and are used for storing or hanging objects such as towels and clothes. In order to avoid the water vapor in the bathroom, the accumulated water stains on the surface cause rust or pollution. A pair of brackets respectively disposed on an indoor wall surface, and a plurality of cross bars respectively disposed between the brackets.

A conventional bracket is mainly a solid metal rod, and a plurality of drill holes respectively for inserting the cross rods are drilled on the rod body. However, such a stent has the disadvantage of being heavy because it is a solid structure. On the other hand, since the crossbars are fixed in such a manner as to be inserted into the drilled holes, in order to be able to be stably joined, the diameters of the drilled holes must be slightly smaller than the diameters of the crossbars, thus In the process of inserting, the insertion of the bracket will be slightly deformed, and the appearance will be less beautiful.

In order to improve the above-mentioned shortcomings, another conventional bracket design, as disclosed in the Chinese Patent No. M267987, is that the crossbars are respectively inserted in a plurality of lateral circular holes of a hollow straight tube. Reuse A long rod that can be inserted into the hollow straight tube passes through the cross rods to reach the limit position. However, such a design still has the following disadvantages:

1. In order to achieve a stable structure, the crossbars and the long rods need to be tightly coupled, so the precision requirements in assembly will lead to inconvenience in processing and increase production costs.

2. The operator will indirectly apply force to the bracket when placing or taking the object. In the long run, the joint between the crossbar and the long pole will be seriously worn and the structure will be loose. If the material of the bracket and the crossbar is metal, it is more likely to be rusted due to wear, which will affect the stability of the structure.

3. In such a design, the crossbars need to be inserted into the lateral circular holes in order to be assembled, and the assembly is relatively inconvenient by the long rod locking limit.

Another example is the Republic of China New Patent No. M337334, which uses a single frame to fix a plurality of crossbars. Although the structural strength of the M267987 is improved, the frame fixed by welding can only provide a standard size and cannot be elastically matched with different lengths. Crossbar, it is not convenient to use. Moreover, in addition to the acute angle generated by the welding, the weld bead generated by the welding is also prone to rust due to moisture in the bathroom, which may affect the appearance and safety. In addition, the brackets made by welding are bulky and difficult to store, and the brackets of the same weight require a large space for handling, which increases operating costs.

Therefore, the object of the present invention is to provide a bracket which is light in weight and can be elastically matched with cross bars of different sizes, and the bracket can be used In addition to the need to reduce the precision required for assembly, a plurality of connectors can be used to avoid rusting of the metal components due to wear and the advantages of convenient assembly.

Therefore, the bracket of the present invention is suitable for being disposed in a fixing base and connected by a loading unit, and comprises a supporting unit and a connecting unit.

The support unit includes a pipe body connected to the fixing base and extending along a first axis and surrounding a cavity, and a connecting shaft extending along the first axis and disposed in the cavity of the pipe body. The tubular body has at least one support aperture in communication with the chamber.

The connecting unit includes at least one pair of connecting members disposed on the supporting holes, the connecting member has a connecting portion disposed on the connecting shaft, and a locking portion opposite to the connecting portion and configured to connect the loading unit.

The effect of the invention is that it has the advantage of being lightweight due to the design of the tube. In addition, by using the design of the connecting member of the connecting unit, the supporting unit can be applied to the loading unit of different specifications, and the components are reduced in accuracy during assembly, and the utility model can be assembled conveniently and stably combined with each other. .
