DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will Figure 1 - be further described in detail with reference to the Figure 3 accompanying drawings to make a further detailed description of the present application.

[0031] Embodiment

[0032] A square welding nut that is convenient for installation, referring to Figure 1 and Figure 2 , includes a nut 1. One side of the nut 1 is fixedly welded with a screw 20. Two mounting cylinders 23 are arranged on the outer surface of the screw 20. One side of the opposite surfaces of the two mounting cylinders 23 is fixedly welded with a mounting plate 24. The mounting cylinder 23 and the mounting plate 24 can limit and fix the welding nut. On one side of the opposite surfaces of the two mounting plates 24, welding bottom plates 25 that are used in cooperation are arranged. The mounting plate 24 can limit the movement of the welding bottom plate 25.

[0033] Referring to Figure 2, anti-slip layers 21 are fixed to the outer surfaces of the two mounting cylinders 23 by adhesives. On one side of each mounting cylinder 23 and the mounting plate 24, mounting screw grooves 22 that cooperate with the screw 20 are jointly formed. Each mounting cylinder 23 and the mounting plate 24 are symmetrically distributed on the outer surface of the screw 20. The mounting cylinder 23 can increase the friction coefficient during installation and fixation through the anti-slip layer 21. The mounting cylinder 23 and the mounting plate 24 can move on the outer surface of the screw 20 through the mounting screw grooves 22, so that the mounting cylinder 23 and the mounting plate 24 can fix the two welding nuts in the middle.

[0034] Refer to Figure 3 , on one side of the opposite surfaces of the two mounting plates 24, welding screw plates 30 are welded and fixed. On one side of the opposite surfaces of the two welding screw plates 30, a plurality of welding points 32 are provided. Welding can be performed more precisely through the welding points 32. On the opposite sides of the two welding bottom plates 25, stacking grooves 31 that cooperate with each other are formed. The welding nuts can be stacked through the stacking grooves 31.

[0035] Refer to Figure 3 , on one side of the opposite surfaces of the two welding screw plates 30 and on one side of the inner surfaces of the two stacking grooves 31, protective rings 33 that cooperate with the screw 20 are welded. There are eight welding points 32, and every four welding points 32 are respectively annularly distributed on one side of the opposite surfaces of the two welding screw plates 30. On one side of the two welding screw plates 30, welding screw grooves 34 that cooperate with the screw 20 are formed. The screw 20 can be shielded during welding through the protective ring 33 to prevent the welding nuts from not being removable from the screw 20 later. The annular distribution of the welding points 32 provides welding positions at multiple angles, so that the welding screw plate 30 can move on the outer surface of the screw 20 through the welding screw groove 34.

[0036] The implementation principle of the embodiment of this application is as follows: When it is necessary to install and fix the square welding nuts, first put one mounting cylinder 23 and the mounting plate 24 on the outer surface of the screw 20, with the mounting plate 24 facing outwards. Then, put the two welding nuts on the appropriate positions of the screw 20 facing each other, and then screw in the other mounting cylinder 23, so that the two mounting plates 24 can move towards the position of the welding nuts and clamp and fix the welding bottom plates 25 on the welding nuts, thereby achieving the purpose of effectively installing and fixing the square welding nuts;

[0037] The mounting cylinder 23 can increase the friction coefficient during installation and fixation through the anti-slip layer 21. The mounting cylinder 23 and the mounting plate 24 can move on the outer surface of the screw 20 through the mounting screw grooves 22, so that the mounting cylinder 23 and the mounting plate 24 can fix the two welding nuts in the middle;

[0038] When it is necessary to weld and fix the square welding nut, align the welding equipment with the appropriate welding point 32 on the welding screw plate 30 for welding, so that the welding point 32 can assist in welding. Since the outer surface of the welding screw plate 30 is an inclined surface, there will be a gap when it fits with other structures. The gap can be filled during welding, thereby improving the welding stability, and thus achieving the purpose that the square welding nut can be effectively welded;

[0039] The screw 20 can be shielded during welding through the protective ring 33 to prevent the welded nut from not being removable from the screw 20 later. The welding points 32 are annularly distributed to provide welding positions at multiple angles, so that the welding screw plate 30 can move on the outer surface of the screw 20 through the welding screw groove 34.

[0040] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same parts are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
