[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] This embodiment provides a round pipe connection joint, which relates to the field of parts connection, such as Figure 1 and Figure 2 As shown, the round tube connecting joint includes a base 1, multiple connecting components 2 and multiple adjusting parts 3, and the multiple connecting components 2 are respectively connected to the base 1; the number of adjusting parts 3 corresponds to the number of connecting components 2 one by one, and the round tube 100 is sleeved on a connecting component 2, and the adjusting part 3 is used to adjust the distance between the connecting component 2 and the round tube 100 so that the connecting component 2 and the round tube 100 have an interference fit.

[0031] The round tube connection joint provided in this embodiment is provided with multiple groups of connection components 2 connected to the base 1, so as to realize the connection of multiple round tubes 100. One connection component 2 is correspondingly provided with an adjusting member 3, and the round tube 100 is sleeved on the connection component 2. The adjusting member 3 adjusts the distance between the connection component 2 and the inner wall of the round tube 100, so that the connection component 2 and the round tube 100 achieve an interference fit, and the round tube 100 is fixed to the round tube connection joint. Compared with the welding of the prior art, the round tube connection joint provided in this embodiment does not need to connect multiple round tubes 100 by welding, which reduces the construction difficulty and improves the work efficiency. Compared with the plug-in joint, the round tube connection joint provided in this embodiment has an interference fit between the connection component 2 and the round tube 100, which enhances the connection strength of the round tube 100.

[0032] Specifically, in this embodiment, the base 1 is an L-shaped structure, which is convenient for factory production and reduces the difficulty of processing the base 1. In other embodiments, the base 1 can be other structures as long as it can be connected to the connecting component 2.

[0033] Specifically, two groups of connection components 2 are provided, and the two groups of connection components 2 are respectively connected to the two ends of the base 1. Then the two round tubes 100 are respectively connected to the two groups of connection components 2, so that the two round tubes 100 are vertically distributed, which is suitable for most production operation requirements. It can be understood that in other embodiments, multiple connection components 2 can be provided to be respectively connected to the base 1, and then multiple round tubes 100 can be respectively connected to the connection components 2, so that the connection of multiple round tubes 100 can be achieved. Among them, the number of round tubes 100 corresponds to the number of connection components 2.

[0034] Specifically, in this embodiment, the base 1 and the connecting assembly 2 are integrally formed. The integrally formed arrangement reduces the number of parts, reduces the difficulty of processing, and enhances the connection strength between the base 1 and the connecting assembly 2.

[0035] Alternatively, if Figure 2 As shown, the connection assembly 2 includes a first connection arm 21 and a second connection arm 22, the first connection arm 21 is connected to the base 1; the second connection arm 22 is connected to the base 1, the second connection arm 22 and the first connection arm 21 are symmetrical along the first plane, the first plane is a horizontal plane, and the adjustment member 3 is used to adjust the distance between the first connection arm 21 and the second connection arm 22 so that the first connection arm 21 and the second connection arm 22 can respectively abut against the inner wall of the round tube 100. The first connection arm 21 and the second connection arm 22 are symmetrically arranged along the first plane, and there is a gap between the first connection arm 21 and the second connection arm 22. The adjustment member 3 adjusts the distance between the first connection arm 21 and the second connection arm 22 and the inner wall of the round tube 100 by adjusting the size of the gap, so that the first connection arm 21 and the second connection arm 22 of the connection assembly 2 achieve interference fit with the round tube 100.

[0036] Specifically, Figure 2 As shown, the circular tube 100 is provided with a first through hole 101, and the first connecting arm 21 is provided with a second through hole corresponding to the first through hole 101. The first through hole 101 and the second through hole are provided to facilitate the passage of the adjusting member 3. The adjusting member 3 passes through the first through hole 101 and the second through hole in turn and can abut against the second connecting arm 22, thereby adjusting the gap size between the first connecting arm 21 and the second connecting arm 22.

[0037] Specifically, Figure 2As shown, the adjusting member 3 includes a straight rod portion 31 and a first stopper portion 32 provided at one end of the straight rod portion 31. The straight rod portion 31 passes through the first through hole 101 and the second through hole in sequence. The first stopper portion 32 passes through the first through hole 101 and abuts against the first connecting arm 21. The end of the straight rod portion 31 away from the first stopper portion 32 can abut against the second connecting arm 22. Preferably, the first through hole 101 needs to be passed through by the first stopper portion 32, and the second through hole only needs to be passed through by the straight rod portion 31. Therefore, the diameter of the first through hole 101 is greater than the diameter of the second through hole to prevent the first stopper portion 32 from abutting against the outer wall of the round tube 100 and damaging or abrading the round tube 100. The adjusting member 3 can be a screw or a bolt. In this embodiment, the adjusting member 3 is a screw. In other embodiments, the adjusting member 3 can be any structure as long as it can achieve the function of adjusting the gap size between the first connecting arm 21 and the second connecting arm 22.

[0038] Specifically, Figure 2 As shown, the first connecting arm 21 is provided with a receiving groove 211, and the receiving groove 211 is used to receive the first stopper 32. After the adjustment is completed, the first stopper 32 is arranged in the receiving groove 211 to prevent the construction personnel from accidentally touching the first stopper 32.

[0039] Specifically, the second connecting arm 22 is provided with anti-skid patterns, which are used to increase the friction between the second connecting arm 22 and the inner wall of the round tube 100. Preferably, the first connecting arm 21 is also provided with anti-skid patterns, which are used to increase the friction between the first connecting arm 21 and the inner wall of the round tube 100. The anti-skid patterns are provided to further prevent the round tube 100 from being separated from the connecting assembly 2 and causing connection failure.

[0040] Specifically, Figure 2 As shown, the base 1 is provided with an annular boss 11 along its circumference, and the round tube 100 is sleeved on the connecting component 2 and abuts against the annular boss 11. When the round tube 100 abuts against the annular boss 11, it proves that the round tube 100 has been completely sleeved on the connecting component 2, and the distance between the connecting component 2 and the inner wall of the round tube 100 can be adjusted by using the adjusting member 3.

[0041] This embodiment provides the steps for installing the round tube connection joint and the round tube 100:

[0042] First, the round tube 100 is sleeved on the connecting component 2. When the round tube 100 abuts against the annular boss 11, it proves that the round tube 100 has been completely sleeved on the connecting component 2.

[0043] Then, the screw is passed through the first through hole 101 and the second through hole in turn and abuts against the second connecting arm 22, and the screw is turned to increase the gap between the first connecting arm 21 and the second connecting arm 22 until the first connecting arm 21 and the second connecting arm 22 respectively abut against the inner wall of the round tube 100, thereby achieving an interference fit between the connecting component 2 and the round tube 100.
