Abstract
Description
Technical Field

Detailed Implementation
[0030] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.
[0031] like Figures 1 to 8 As shown, this embodiment proposes a splicing square tube connection structure, including:
[0032] A first square tube 11 is provided with a first locking port 12 through the two opposite sides of the first square tube 11, and a first guide channel 13 through the first locking port 12 is provided at the end of the first square tube 11.
[0033] The second square tube 14 has a second locking port 15 that passes through between two opposite sides of the second square tube 14, and the end of the second square tube 14 has a second guide channel 16 that passes through the second locking port 15.
[0034] Locking member 17, the locking member 17 includes a connecting part 18, a first locking part 19 and a second locking part 20, one end of the connecting part 18 is provided with the first locking part 19, and the other end of the connecting part 18 is provided with the second locking part 20.
[0035] The first locking part 19 is installed in the first locking port 12, the second locking part 20 is installed in the second locking port 15, and the connecting part 18 is disposed through the first guide channel 13 and the second guide channel 16;
[0036] A limiting member having a through opening is provided, and the limiting member is sleeved between the first square tube 11 and the second square tube 14 through the through opening to prevent the locking member 17 from falling off.
[0037] The construction process of this plan is as follows:
[0038] After aligning the first square tube 11 and the second square tube 14, insert the locking member 17 into the first locking port 12 and the second locking port 15 along a direction perpendicular to the surfaces of the first square tube 11 and the second square tube 14. At this time, the first locking port 12 engages with the first locking part 19, and the second locking port 15 engages with the second locking part 20. As long as the locking member 17 does not fall off, the first square tube 11 and the second square tube 14 will not separate. Therefore, a limiting member is used. Since the limiting member is located between the first square tube 11 and the second square tube 14, it effectively blocks the locking member 17, leaving no room for movement. This method is similar to the working principle of a tenon joint, effectively ensuring the connection strength of the first square tube 11 and the second square tube 14, and has the advantages of high construction efficiency and time saving.
[0039] Furthermore, the first guide channel 13 and the first locking port 12 form a T-shaped structure, and the first locking part 19 is T-shaped.
[0040] Furthermore, the second guide channel 16 and the second locking port 15 form a T-shaped structure, and the second locking part 20 is T-shaped.
[0041] In one embodiment of this invention, the limiting member is a third-party tube 21.
[0042] Furthermore, the first square tube 11 or the second square tube 14 is provided with a threaded hole, and the third square tube 21 is fixed in the threaded hole by a screw 23; the third square tube 21 is provided with an adjustment port 22, the adjustment port 22 is in communication with the threaded hole, and the screw 23 passes through the adjustment port 22.
[0043] In the initial state, the third-party tube 21 does not cover the locking member 17. After the locking member 17 is installed, adjust the third-party tube 21 so that it moves to the locking member 17 and covers the locking member 17. Then tighten the screw 23 to lock the position of the third-party tube 21. At this time, the first square tube 11 and the second square tube 14 can be installed firmly.
[0044] In one embodiment of this invention, the first square tube 11 and the second square tube 14 are straight square tubes. In this case, when the locking member is the third square tube 21, the third square tube 21 is also a straight square tube. Alternatively, the locking member 17 can also employ other structures, such as a clamp assembly. Combined with... Figure 4 and Figure 5 As shown, the clamp assembly includes a first clamp part 24 and a second clamp part 25. The first clamp part 24 and the second clamp part 25 are located on both sides of the first square tube 11 and the second square tube 14, respectively. The first clamp part 24 and the second clamp part 25 are fixed together by a bolt assembly 26, which can realize the limiting of the locking member 17.
[0045] In addition, such as Figure 6 and Figure 7 As shown, the first square tube 11, the second square tube 14, and the third square tube 21 can also be arc-shaped square tubes.
[0046] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
