Description

Combination structure of cargo rack

This creation is about a combination structure of a cargo rack, especially a combination structure that can make the extrusion of plastic hollow plates more convenient and easier.

Press, it is generally common to extrude the plastic hollow sheet combination cargo rack, please refer to Fig. 1-2, mainly on the main board 10 with the screw element N to screw the joint block 11 in place, and then insert the convex column above the joint block 11 into the side plate 12 , and screwed with the screw element N, there are still many inconveniences in use.

For this reason, in view of the above-mentioned deficiencies in the conventional structure, the creator has been engaged in the research and development and practical experience of related products for many years. In response to the above deficiencies, he made detailed design improvements and finally developed this creation.

The main purpose of this creation is to provide a cargo rack assembly structure that can be assembled by yourself and is extremely easy.

In order to achieve the above purpose, the technical means used in this creation are: a cargo rack assembly structure, which mainly includes: a main board, which is provided with an engaging hole and a positioning hole at an appropriate position on one side; a side board, which is assembled on the main board On the top, the side plate is provided with a screw connection hole; the combination block is assembled on the engaging hole of the main board, the upper part of the combination block is provided with a convex column and a positioning hole, and the bottom is convexly provided with a locking convex column and a positioning convex body, The cargo rack can be easily assembled by the above-mentioned components.

In order to make the technical means, creative features, goals and effects used in this creation easy to understand, a preferred embodiment is given and explained in detail with the drawings as follows: First, please refer to Figures 3 to 9, the embodiment of this creation It is mainly composed of an extruded plastic hollow main board 2, an extruded plastic hollow side plate 3 and a combination block 4, wherein the main board 2 is provided with an engaging hole 20 and a positioning hole 21 at an appropriate position on one side, wherein the center point of the engaging hole 20 and the positioning hole are The center points of 21 are not on the same horizontal line; the side plate 3 is arranged on the main plate 2, and the side plate 3 is provided with a screw hole 31 on the front plate body 30; the combination block 4 is assembled on the main plate 2, the A convex post 40 and a positioning hole 41 are protruded from the top of the combination block 4 , and a locking convex post 42 and a positioning convex body 43 are protruded from the bottom. On the horizontal line, the engaging protrusion 42 is provided with There are grooves 420 and inclined surfaces 421, and the positioning protrusions 43 are provided with inclined surfaces 430 and retaining surfaces 431, and the diameter of the engaging protrusions 42 is slightly smaller than the engaging holes 20 of the main board 2. The diameter is slightly smaller than the positioning hole 21 of the main board 2 .

When used in combination, first align the engaging protrusions 42 of the coupling block 4 with the engaging holes 20 of the main board 2 and insert them, and then push the coupling block 4 forward, so that the grooves 420 of the engaging protrusions 42 are inserted into the motherboard 2 , At this time, the positioning protrusions 43 of the coupling block 4 are engaged with the positioning holes 21 of the main board 2 , and the grooves 420 of the engaging protrusions 42 are inclined, so that the main board 2 can be tightly engaged with the coupling block 4 without loosening. , the combination block 4 is stably fixed on the main board 2, and then the hollow hole of the side plate 3 is aligned with the convex column 40 above the combination block 4 to be embedded and positioned, and the screw element N is inserted through the screw hole 31 of the side plate 3 And it is screwed with the positioning hole 41 of the combination block 4, whereby a stable and easy-to-assemble cargo rack assembly structure can be easily completed.

Through the above technical means, this creation actually has the following enhancement effects:

1. This creation provides the user to easily complete the assembly. Since the engaging hole 20 and the positioning hole 21 of the main board 2 are not on the same horizontal line, the engaging protruding post 42 and the positioning protruding body 43 of the combining block 4 on the same horizontal line can be closely aligned. combine.

2. The engaging holes 20 and the positioning holes 21 on the main board 2 have been processed, and the user can easily combine the combination block 4 on the main board 2 .

3. The grooves 420 on the engaging protrusions 42 are designed with inclined surfaces, so that the main board 2 and the combination block 4 can be more tightly engaged.

4. The bottom and front ends of the positioning protrusions 43 on the coupling block 4 are designed with an inclined surface, so that the positioning protrusions 43 are more smoothly engaged with the positioning holes 21 on the main board 2 .

To sum up, it is only a preferred embodiment of this creation, and it should not limit the scope of implementation of this creation, that is, any equivalent changes or modifications made according to the patent scope and description content of this creation should still belong to covered by this creative patent.
