[0020] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] Example: Figure 1-3 As shown, the utility model is convenient for connecting and assembling a hollow square pile, comprising a first connecting member and a second connecting member installed at the end of the hollow square pile, the first connecting member comprising a first end plate 1, a connecting square head 2 is arranged at the center of one side of the first end plate 1 away from the hollow square pile, the first end plate 1 is provided with fixing members at positions close to the four sides of the connecting square head 2, the second connecting member comprises a second end plate 5, a connecting square groove 6 is arranged at the side of the second end plate 5 away from the hollow square pile, the four sides of the connecting square groove 6 are provided with fixing slots 7, and fixing card slots 8 are arranged on both side walls of the connecting slot, and the position of the fixing slot 7 corresponds to the position of the fixing member.

[0022] Among them, the fixing part includes an elastic plug rod 3 fixedly connected to the first end plate 1, and a fixed block 4 is arranged on one side of the elastic plug rod 3 at a position away from the first end plate 1. The number of elastic plug rods 3 in each fixing part is two, and the two fixed blocks 4 are respectively located on the side away from the two elastic plug rods 3. The bottom of the fixed block 4 is inclined to facilitate the insertion of the fixed plug rod into the fixed slot 7.

[0023] The distance between the two elastic insertion rods 3 in the fixing member and the sides thereof that are away from each other is equal to the width of the fixing slot 7 .

[0024] The opening size of the fixing slot 7 is larger than the distance between its two side walls, and the distance between the two fixing blocks 4 in the fixing piece on the far side is smaller than the opening size of the fixing slot 7, so that the fixing piece can enter through the opening of the fixing slot 7.

[0025] Among them, rotating parts 9 are installed on the four sides of the second end plate 5, one end of the four rotating parts 9 is respectively inserted into the four fixed slots 7, and the inserted end is connected with a locking part 10, which is located in the middle position between the inner walls on both sides of the fixed slot 7.

[0026] Among them, the length of the locking member 10 is equal to the distance between the opposite sides of the two elastic rods 3 in the fixing member, and the width is smaller than the distance between the opposite sides of the two elastic rods 3 in the fixing member. When the locking member 10 is placed horizontally between the two elastic rods 3, it can prevent the two elastic rods 3 from bending inward and causing the fixed block 4 to withdraw from the fixed slot 8.

[0027] Working principle:

[0028] When the utility model is used to butt joint two hollow square piles, it is only necessary to insert the connecting square head 2 located on the first end head plate 1 of one of the hollow square piles into the connecting square groove 6 located on the second end head plate 5 of the other hollow square pile. During the insertion process, the fixing members located on the four sides of the connecting square head 2 will simultaneously enter the fixing slots 7 located on the four sides of the connecting square groove 6. Since the opening size of the fixing slot 7 is large, during the entry process, the elastic plug rod 3 will bend toward the inside of the fixing slot 7, so that the process of the elastic plug rod 3 entering the fixing slot 7 will not be affected. When the two ends of the hollow square pile are connected, the locking member 10 is driven by the four rotating members 9 to rotate, so that the locking member 10 is placed horizontally between the two elastic rods 3 of the two fixing members, and the elastic rod 3 is progressively advanced between the two elastic rods 3 by the locking member 10, so as to prevent the fixation from loosening. Through the above structure, the speed and efficiency of the hollow square pile connection can be greatly improved.

Those skilled in the art should understand that this example is only for facilitating understanding of the utility model, and any specific details thereof are not intended to limit the utility model in any way.

[0030] Those skilled in the art should understand that the purpose of the above description of the embodiments of the present invention is only to exemplarily illustrate the beneficial effects of the embodiments of the present invention, and is not intended to limit the embodiments of the present invention to any given examples.
