The following will be explained in conjunction with Figures 1 to 6 carry out the explanation.
[0030] Some specific embodiments described below are intended to facilitate the understanding of those skilled in the art of this embodiment, and this embodiment is not limited to some specific embodiments described below.
[0031] Refer to Figure 1 and Figure 3 A square pipe connection structure provided by an exemplary embodiment of the present disclosure, the square pipe connection structure includes:
[0032] The joint 2 is used for being inserted into two square pipes 1 to be connected simultaneously. The joint 2 has a channel 21 communicating the two square pipes 1 to be connected, and the joint 2 covers the area between the ports of the two square pipes 1;
[0033] The first centering structure 11 is arranged on the inner wall of the square pipe 1 and / or the outer wall of the joint 2. The first centering structure 11 is used to prevent the joint 2 from deviating from the square pipe 1 during the movement of the joint 2;
[0034] The second centering structure 3 is arranged on the inner wall of the square pipe 1 and is used to abut the bottom wall of the joint 2 against the inner bottom wall of the square pipe 1.
[0035] Exemplarily, refer to Figure 1 The joint 2 is in the shape of a C-shaped steel adapted to the inner contour of the square pipe 1. The end face of the joint 2 is in the shape of a C corresponding to the inner contour size of the square pipe 1. The two ends of the joint 2 can be respectively inserted into the interiors of two square pipes 1 extending in the same direction.
[0036] Refer to Figure 1 and Figure 2, the square tube 1 has two vertically arranged and opposite side walls and a horizontally arranged bottom wall. The two side walls of the square tube 1 are integrally formed on the opposite sides of the bottom wall of the square tube 1 respectively. The first pair of centering structures 11 includes a first guiding inclined surface 111 arranged at the end of the inner side wall of the square tube 1. The first guiding inclined surface 111 extends from the inner side wall of the square tube 1 to the end surface of the square tube 1. The inner diameter of the square tube 1 at the position where the first guiding inclined surface 111 is provided gradually increases towards this end surface direction. For example, the original thickness of the side wall of the square tube 1 is 10 mm, and the maximum depth of the first guiding inclined surface 111 is 5 mm, so that the end surface thickness of the square tube 1 after the first guiding inclined surface 111 is provided is 5 mm, making the port of the square tube 1 in a flared structure, and the side wall thickness between the first guiding inclined surface 111 and the other end of the square tube 1 is still 10 mm. There are four first guiding inclined surfaces 111, and they are divided into two groups and arranged at both ends of the square tube 1 respectively. The two first guiding inclined surfaces 111 at the same end of the square tube 1 are arranged on the opposite side walls of the square tube 1 and are oppositely arranged.
[0037] When the joint 2 is inserted into the square tube 1, the edge of the end surface side of the joint 2 first contacts the first guiding inclined surface 111. The flared structure formed by the two first guiding inclined surfaces 111 oppositely arranged at the port of the square tube 1 can provide a larger accommodation space for the joint 2. The end of the joint 2 can be easily docked with the inner wall port of the square tube 1 under the limiting and guiding action of the first guiding inclined surface 111 and inserted into the square tube 1.
[0038] Refer to Figure 1 and Figure 3 , the second pair of centering structures 3 includes an abutting surface 32 arranged on the inner wall of the square tube 1 and used for abutting against the top surface of the joint 2, and a second guiding inclined surface 33 arranged on the inner wall of the square tube 1. The second guiding inclined surface 33 extends from the end of the abutting surface 32 in an obliquely upward direction to the port of the square tube 1. A limiting block 31 is fixedly connected to the inner side wall of the square tube 1. The limiting block 31 is welded to the inner side wall of the square tube 1 and protrudes into the inner space of the square tube 1. The bottom surface of the limiting block 31 is flat and parallel to the inner bottom wall of the square tube 1. The bottom surface of the limiting block 31 forms the abutting surface 32. Among them, the shortest straight-line distance between the abutting surface 32 and the inner bottom wall of the square tube 1 is equal to the height of the joint 2; the side wall of the limiting block 31 facing the port direction of the square tube 1 extends from the bottom surface of the limiting block 31 in an obliquely upward direction and extends to the top surface of the limiting block 31 along the direction towards the port of the square tube 1. This side wall of the limiting block 31 forms the second guiding inclined surface 33, and the second guiding inclined surface 33 is located in the area between the abutting surface 32 and the first guiding inclined surface 111.
[0039] After the port of the connector 2 is inserted into the square pipe 1 under the limiting and guiding action of the first guiding inclined surface 111, the port of the connector 2 moves to the limiting block 31. The bottom edge of the port of the connector 2 abuts against the second guiding inclined surface 33 and moves towards the inner bottom wall of the square pipe 1 under the limiting and guiding action of the second guiding inclined surface 33. As the connector 2 continues to penetrate, the top side of the end surface of the connector 2 is flush with the abutting surface 32. At this time, the outer bottom wall of the connector 2 abuts against the inner bottom wall of the square pipe 1. Continuing to move the connector 2 into the square pipe 1, the top surface of the outer side wall of the connector 2 abuts against the abutting surface 32. At this time, the connector 2 is vertically clamped with the square pipe 1 through the limiting block 31.
[0040] In this embodiment, through the first centering structure 11, a horizontal limiting effect can be exerted on the square pipe 1 to be connected during the installation of the connector 2, so that the two square pipes 1 to be connected are aligned in the horizontal direction. And through the second centering structure 3, a vertical limiting effect can be exerted on the square pipe 1 to be connected during the installation of the connector 2, so that the two square pipes 1 to be connected are aligned in the vertical direction. Combining with the connector 2, the area exposed between the ends of the two square pipes 1 to be connected is covered, and the two square pipes 1 to be connected form a continuous medium channel 21.
[0041] It should be understood that the channel 21 formed inside the connector 2 is for the media inside the two square pipes 1 to be connected to be stably and smoothly exchanged. In order to make the space inside the two square pipes 1 flatter to reduce the influence on the flow of the media inside the square pipes 1, the edge of the abutting surface 32 can also be set to be flush with the inner wall of the channel 21, that is, the thickness of the limiting block 31 is the same as the thickness of the side wall of the connector 2. This setting also makes the edge of the second guiding inclined surface 33 flush with the inner wall of the channel 21.
[0042] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 , it further includes a third guiding inclined surface 12 provided on the square pipe 1. The third guiding inclined surface 12 extends from the inner bottom wall of the square pipe 1 to the end surface of the square pipe 1.
[0043] Exemplarily, referring to Figure 1 and Figure 2 , the inner diameter of the square pipe 1 at the position where the third guiding inclined surface 12 is provided gradually increases towards this end surface direction. For example, the original thickness of the side wall of the square pipe 1 is 10 mm, and the maximum depth of the third guiding inclined surface 12 is 5 mm, so that the end surface thickness of the square pipe 1 after the third guiding inclined surface 12 is provided is 5 mm, and the side wall thickness between the third guiding inclined surface 12 and the other end of the square pipe 1 is still 10 mm. Combining with the first guiding inclined surface 111 provided at the port of the square pipe 1, the port of the square pipe 1 has a flared structure.
[0044] In this embodiment, there are two third guiding inclined surfaces 12, which are respectively arranged at both ends of the square tube 1. When the joint 2 is inserted into the square tube 1, the bottom side edge of the end surface of the joint 2 first contacts the third guiding inclined surface 12. The flared structure formed by the third guiding inclined surface 12 arranged at the port of the square tube 1 can provide a larger accommodation space for the joint 2. Under the limiting and guiding action of the third guiding inclined surface 12, the end of the joint 2 can easily dock with the inner wall port of the square tube 1 and be inserted into the square tube 1.
[0045] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 4 , the bottom surface of the joint 2 has a convex edge 24 that protrudes outward and is used to fill the gap between the ports of two adjacent square tubes 1. The outer wall of the convex edge 24 is coplanar with the outer wall of the square tube 1.
[0046] Exemplarily, referring to Figure 4 and Figure 5 , the convex edge 24 extends around the outer contour of the joint 2 from the top end of one side wall of the joint 2 to the top end of the other side wall of the joint 2. The convex edge 24 is in a C shape adapted to the outer contour of the joint 2. The convex edge 24 is connected to the joint 2 by bolts 23. The threaded end of the bolt 23 penetrates the inner side wall of the joint 2 and extends into the solid interior of the convex edge 24. The head of the bolt 23 is located in the channel 21. Two bolts 23 respectively arranged on the two inner side walls of the joint 2 jointly fix the convex edge 24 to the joint 2.
[0047] The convex edge 24 is fixed at the middle length position of the joint 2. The two ends of the joint 2 are respectively used for plugging two square tubes 1 to be connected. After the two square tubes 1 are connected by the joint 2, the internal spaces of the two square tubes 1 are communicated through the channel 21 of the joint 2, but the gap between the end faces of the two square tubes 1 still exists. The convex edge 24 fixed on the outer wall of the joint 2 can fill this gap, and by setting the outer wall of the convex edge 24 to be coplanar with the outer wall of the square tube 1, the two square tubes 1 connected by the joint 2 are also in a continuous state on the outer wall.
[0048] In this embodiment, referring to Figure 4 and Figure 6, the third guiding inclined surface 12 is formed on the inner bottom wall of the square pipe 1 and extends to the bottom of the end surface of the square pipe 1, that is, the port of the square pipe 1 has a flared structure extending downward. The bottom wall of the joint 2 is horizontally arranged. When the joint 2 is inserted into the square pipe 1 and the outer bottom wall of the joint 2 abuts against the inner bottom wall of the square pipe 1 under the action of the abutting surface 32, a gap gradually narrowing from the port of the square pipe 1 to the inside of the square pipe 1 will be formed between the third guiding inclined surface 12 and the outer bottom wall of the joint 2. Part of the convex edge 24 fills at least part of the area between the third guiding inclined surface 12 and the joint 2. An avoidance groove 25 is formed on one side of the convex edge 24 facing the end of the joint 2. The avoidance groove 25 extends from the outer wall of the convex edge 24 towards the outer wall of the joint 2. The avoidance groove 25 forms a fourth inclined surface 26 adapted to the third guiding inclined surface 12 on the horizontal section of the convex edge 24 and forms a fifth inclined surface 27 adapted to the first guiding inclined surface 111 on the vertical section of the convex edge 24. After the joint 2 connects the two square pipes 1, the port of the square pipe 1 is inserted into the avoidance groove 25, and part of the convex edge 24 extends into the gap between the outer bottom wall of the joint 2 and the third guiding inclined surface 12, and the fourth inclined surface 26 abuts against the third guiding inclined surface 12. At the same time, part of the convex edge 24 extends into the gap between the outer wall of the joint 2 and the first guiding inclined surface 111, and the fifth inclined surface 27 abuts against the first guiding inclined surface 111.
[0049] In an exemplary embodiment of the present disclosure, with reference to Figure 3 and Figure 5 , a stopper 22 for hindering the joint 2 from continuing to move in the same direction after contacting the abutting surface 32 is provided on the top surface of the joint 2. When the stopper 22 contacts the abutting surface 32, the outer wall of the convex edge 24 is joined to the outer wall of the square pipe 1.
[0050] Exemplarily, with reference to Figure 3 and Figure 5 , the stopper 22 is fixed at a position near the port on the top surface of the side wall of the joint 2, and the side wall of the stopper 22 facing the port is in the shape of an inclined surface adapted to the second guiding inclined surface 33. After the joint 2 extends into the square pipe 1, the joint 2 continues to move along the length direction of the square pipe 1 and can stop after the stopper 22 abuts against the second guiding inclined surface 33. At this time, the port of the square pipe 1 is inserted into the avoidance groove 25, and part of the convex edge 24 extends into the gap between the outer bottom wall of the joint 2 and the third guiding inclined surface 12, and the fourth inclined surface 26 abuts against the third guiding inclined surface 12. At the same time, part of the convex edge 24 extends into the gap between the outer wall of the joint 2 and the first guiding inclined surface 111, and the fifth inclined surface 27 abuts against the first guiding inclined surface 111.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
