[0009] Furthermore, threaded through holes and clearance through holes are respectively provided on opposite sides of the connector. The locking member passes through the mounting through hole, the threaded through hole and the clearance through hole in sequence and abuts against the inner wall of the first tube.
[0010] Furthermore, the mounting through hole is a threaded hole, and a clearance channel is formed on the tube wall of the connector for the locking member to pass through. The locking member passes through the mounting through hole and the clearance channel and abuts against the inner wall of the connector.
[0011] Furthermore, the pipe connection structure includes multiple locking elements, at least two of which have their central axes at an included angle α; and / or, the connector has a notch forming a clearance channel.

[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] See Figures 1 to 6 As shown, this utility model provides a pipe connection structure. The pipe connection structure includes: a first pipe body 10 and a second pipe body 20, arranged sequentially along a first direction; a connector 30 located within the first pipe body 10 and the second pipe body 20, with one end of the connector 30 detachably connected to the first pipe body 10 and the other end connected to the second pipe body 20; and a locking member 40, wherein the first pipe body 10 has a mounting through hole 51, the first end of the locking member 40 passes through the mounting through hole 51, and the second end of the locking member 40 passes through the mounting through hole 51 and abuts against the first pipe body 10 or the connector 30, and the end face of the first end of the locking member 40 does not protrude from the outer wall of the first pipe body 10.
[0027] With the above configuration, on the one hand, the locking member 40 passes through the mounting hole 51 and abuts against the first tube 10 or the connector 30, thus ensuring the stability of the connection between the locking member 40 and the first tube 10; on the other hand, since the end face of the first end of the locking member 40 does not protrude from the outer wall of the first tube 10, an aesthetic effect can also be achieved. This pipe connection structure is simple in structure, high in strength, and low in cost. Furthermore, the locking member 40 is not exposed, and the gap at the junction of the first tube 10 and the second tube 20 can be kept very small, resulting in a more aesthetically pleasing appearance.
[0028] In one embodiment of this utility model, the locking member 40 is a set screw.
[0029] like Figures 1 to 6As shown, in this embodiment of the present invention, the connector 30 is a connecting pipe. Specifically, the connecting pipe can be a square pipe, a round pipe, an elliptical pipe, or an irregularly shaped pipe. Thus, the connector 30 passes through the first pipe body 10 and the second pipe body 20, achieving the function of connecting the first pipe body 10 and the second pipe body 20. Simultaneously, since the connecting pipe, the first pipe body 10, and the second pipe body 20 are all tubular structures, the connector 30 will not damage the structure of the first pipe body 10 and the second pipe body 20. Therefore, after the first pipe body 10 and the second pipe body 20 are connected, they still remain internally connected tubular structures. Furthermore, the connector 30 being located inside the first pipe body 10 and the second pipe body 20 further enhances the aesthetic appeal.
[0030] like Figures 1 to 6 As shown in the embodiment of this utility model, a welding hole 21 is provided on the second tube 20, and the connector 30 is partially inserted into the second tube 20 and fixedly connected to the second tube 20 through the welding hole 21. After welding is completed, the welding material inside and around the welding hole 21 can be polished to make the outer wall of the second tube 20 look smooth and flat, further ensuring the aesthetics of the tube.
[0031] In this way, the connector 30 is welded to the second tube 20, and the connector 30 is detachably connected to the first tube 10 through the locking member 40, which can achieve both a stable connection and an aesthetically pleasing and easy-to-operate effect.
[0032] In another embodiment of the present invention, the first tube 10 and the second tube 20 can be detachably connected to the connecting member 30 via the locking member 40.
[0033] Example 1
[0034] like Figure 1 and Figure 2 As shown, in Embodiment 1 of this utility model, the connector 30 includes a first section 301 and a second section 302 with successively decreasing outer diameters. The mounting through hole 51 is a threaded hole. The first end of the locking member 40 is threadedly connected to the mounting through hole 51, and the second end of the locking member 40 abuts against the outer wall of the second section 302.
[0035] In the above technical solution, the connector 30 also includes a third segment 303 connecting the first segment 301 and the second segment 302. The outer diameter of the third segment 303 gradually decreases from the first segment 301 to the second segment 302. Since the outer diameter of the second segment 302 is smaller, a portion of the locking member 40 is located inside the first tube 10 and abuts against the second segment 302. Thus, without reducing the length of the locking member 40, the end face of the locking member 40 does not protrude from the outer wall of the first tube 10, avoiding the problem of reduced connection strength between the locking member 40 and the first tube 10 due to reduced length.
[0036] With the above configuration, the locking element 40 is threadedly connected to the mounting through hole 51 and abuts against the outer wall of the second section of the connector 30, thereby enabling the first pipe body 10 and the connector 30 to be detachably locked together. This pipe connection structure is simple in structure, high in strength, and low in cost, and the locking element 40 is not exposed, resulting in a more aesthetically pleasing appearance.
[0037] like Figure 1 and Figure 2 As shown, in Embodiment 1 of this utility model, the pipe connection structure further includes an annular flange 56 connected to the first pipe body 10. The annular flange 56 is connected to the first pipe body 10 and is located on the side of the first pipe body 10 facing the connector 30. The annular flange 56 extends along the edge of the mounting through hole 51 and has a threaded section on its inner wall.
[0038] In the above technical solution, the annular flange 56 is formed on the first tube body 10 by a budding process, which can increase the length of the threaded hole section of the first tube body 10. The locking member 40 is sequentially threaded to the mounting through hole 51 and the annular flange 56, which can strengthen the connection strength between the locking member 40 and the first tube body 10.
[0039] like Figure 1 and Figure 2 As shown, in Embodiment 1 of this utility model, the pipe connection structure includes a plurality of locking members 40, and the central axes of at least two of the plurality of locking members 40 have an included angle β.
[0040] In the above technical solution, multiple locking elements 40 are arranged at intervals in the circumferential direction of the first tube body 10, which can further enhance the connection strength between the first tube body 10 and the connecting element 30.
[0041] Example 2
[0042] The difference between the pipe connection structure of Embodiment 2 and the pipe connection structure of Embodiment 1 lies only in the specific structure of the connector 30 and the specific structure of the first pipe body 10.
[0043] like Figure 3 and Figure 4 As shown, in the second embodiment of this utility model, threaded through holes 54 and clearance through holes 55 are respectively provided on opposite sides of the connector 30. The locking member 40 passes through the mounting through hole 51, the threaded through hole 54 and the clearance through hole 55 in sequence and abuts against the inner wall of the first tube 10.
[0044] In the above technical solution, the mounting through hole 51 is a smooth section, and the locking member 40 is threadedly connected to the threaded through hole 54. In this way, the locking member 40 can connect the first pipe body 10 and the second pipe body 20. This pipe connection structure is simple in structure, high in strength, and low in cost. Moreover, the locking member 40 is not exposed, resulting in a more aesthetically pleasing appearance.
[0045] like Figure 3 and Figure 4 As shown, in Embodiment 2 of this utility model, an annular flange 56 is formed on the inner wall of the connector 30 by a budding process. The annular flange 56 extends along the edge of the threaded through hole 54. The annular flange 56 is different from the annular flange 56 in Embodiment 1 above in only the position, but has the same structure and function, and will not be described again here.
[0046] like Figure 3 and Figure 4 As shown in Embodiment 2 of this utility model, the pipe connection structure includes multiple locking elements 40, which are arranged at intervals along the axial direction of the first pipe body 10. This further enhances the connection stability between the first pipe body 10 and the connecting element 30.
[0047] Example 3
[0048] like Figure 5 and Figure 6 As shown, in Embodiment 3 of this utility model, the mounting through hole 51 is a threaded hole, and a clearance channel is formed on the tube wall of the connector 30 for the locking member 40 to pass through. One end of the locking member 40 is threadedly connected to the mounting through hole 51, and the other end of the locking member 40 passes through the mounting through hole 51 and the clearance channel and abuts against the inner wall of the connector 30.
[0049] In the above technical solution, a notch 57 is provided on the connector 30, forming a clearance channel. The locking member 40 is threadedly connected to the mounting through hole 51 and abuts against the inner wall of the connector 30 to fix the first pipe body 10 and the second pipe body 20 together. This pipe connection structure is simple in structure, high in strength, and low in cost. Moreover, the locking member 40 is not exposed, resulting in a more aesthetically pleasing appearance.
[0050] In another embodiment of this utility model, a through hole may also be provided on the connector 30, forming a clearance channel for the locking member 40 to pass through.
[0051] like Figure 5 and Figure 6 As shown, in Embodiment 3 of this utility model, the pipe connection structure includes a plurality of locking members 40, and the central axes of at least two of the plurality of locking members 40 have an included angle α.
[0052] In the above technical solution, the pipe connection structure includes two locking elements 40, which are arranged vertically at intervals, and the included angle α between the central axes of the two locking elements 40 is 90°. This can further enhance the connection stability between the first pipe body 10 and the connector 30.
[0053] In embodiments of this invention, the included angle α can range from 90° to 120°.
[0054] In one embodiment of this utility model, the pipe connection structure includes three or more locking elements 40.
[0055] like Figure 5 and Figure 6 As shown, in Embodiment 3 of this utility model, an annular flange 56 is formed on the inner wall of the first tube 10 by a budding process. The annular flange 56 has the same setting position, structure and function as the annular flange 56 in Embodiment 1 above, and will not be described again here.
[0056] This utility model also provides a bracket, including a base, a mounting component and the aforementioned pipe connection structure. The lower end of the pipe connection structure is disposed on the base, and the mounting component is disposed on the upper end of the pipe connection structure. The mounting component is suitable for installing or placing items.
[0057] The bracket of this utility model has all the technical features and effects of the above-mentioned tube connection structure, which will not be repeated here.
[0058] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: the locking member passes through the mounting through hole and abuts against the first tube body or the connecting member, thus ensuring the connection stability between the locking member and the first tube body; since the end face of the first end of the locking member does not protrude from the outer wall of the first tube body, an aesthetic effect can also be achieved. The pipe connection structure configured in this way is simple in structure, high in strength, low in cost, and the locking member is not exposed, resulting in a more aesthetically pleasing appearance.
