[0031] The following is combined with Figures 1 to 5 The present invention is further described in detail, but is not intended to limit the present invention.

[0032] like Figure 1As shown, in one embodiment of the present invention, the locking device of the steel structure connector includes a vertical profile 1, a horizontal profile 2 and a built-in locking assembly 3; the horizontal profile 2 is obliquely arranged at the side end of the vertical profile 1; and a first channel 11 is provided in the vertical profile 1; a second channel 21 is provided in the horizontal profile 2; the built-in locking assembly 3 includes a positioning component 31, a locking component 32 and a locking component 33; the positioning component 31 is arranged in the first channel 11; and a positioning channel 311 is provided on the positioning component 31; the positioning component 31 is also provided with a locking hole 314 connected to the positioning channel 311; the locking component 33 is arranged in the second channel 21, and the locking component 32 extends and inserts into the positioning channel 311; the locking component 32 passes through the locking hole 314, and the locking component 32 is respectively connected to the positioning component 31 and the locking component 32. The positioning channel 311 is provided along the horizontal direction of the positioning component 31 and passes through one side end of the positioning component 31 ; the locking hole 314 is provided along the vertical direction of the positioning component 31 .

[0033] The technical solution of the present invention adopts the positioning assembly of the positioning component 31 and the vertical profile 1 and the positioning assembly of the fastening component 33 and the horizontal profile 2, and combines the insertion of the positioning component 31 and the fastening component 33 and the locking and splicing of the locking component 32 with the positioning component 31 and the locking component 32 respectively, which can improve the assembly stability between the vertical profile 1 and the horizontal profile 2, avoid damage or deformation caused by welding between the profiles, thereby improving the safety of use, extending its service life, and improving the overall aesthetics of the finished steel structure profile.

[0034] Specifically, in some embodiments, Figure 1 As shown, the inner wall of the first channel 11 is provided with a support inner plate 12, which is supported and connected to the positioning member 31. This structure can improve the positioning member 31's position-limiting effect through the support performance of the support inner plate 12, and ensure the assembly stability between the positioning member 31 and the vertical profile 1, preventing the positioning member 31 from excessive sliding.

[0035] Specifically, in some embodiments, Figure 1 and 4 As shown, the locking component 33 includes a connecting block 331 and a connecting block 332. The locking block 331 is inserted into the positioning channel 311 and connected to the locking component 32. The connecting block 332 is connected to the second channel 21 in a position-limiting manner. This structure, with its segmented locking block 331 and connecting block 332, ensures the stability of the position-limiting assembly of each component with the vertical profile 1 and horizontal profile 2, thereby improving the overall structural stability. The locking block 331 is square, and the connecting block 332 is cylindrical.

[0036] Specifically, in some embodiments, Figure 1 and4 As shown, the locking block 331 has a vertical locking groove 335 on one side facing the positioning member 31; the locking member 32 is locked and connected to the locking groove 335. The locking member 32 is a threaded rod, and the inner wall of the locking groove 335 has a locking thread surface, and the threaded rod is detachably connected to the locking thread surface.

[0037] Among them, such as Figure 4 As shown, the locking member 33 also includes a protrusion 333; one end of the protrusion 333 is connected to the top of the connecting block 332; the other end of the protrusion 333 passes through the second channel 21 and extends through the horizontal profile 2. This structure, through the protrusion 333, allows the locking member 33 to be driven from above the horizontal profile 2 to slide along the second channel 21 for assembly, thereby improving assembly smoothness and preventing the locking member 33 from falling off the horizontal profile 2 during disassembly.

[0038] Specifically, in some embodiments, Figure 1 and 2 As shown in FIG4 , a clamping plate 312 is provided in the positioning channel 311. A horizontal slot 334 is provided on the side of the fastening member 33 (the fastening block 331 thereof) to match the clamping plate 312. In other words, when the fastening member 33 (the fastening block 331 thereof) is inserted into the positioning channel 311, the clamping plate 312 is engaged with the horizontal slot 334, thereby further improving the assembly stability between the positioning member 31 and the fastening member 33.

[0039] Specifically, in some embodiments, Figure 2 and 3 As shown, the clamping plate 312 has an abutting groove 315 on one end thereof facing the locking member 32; the locking member 32 abuts against the inner wall of the abutting groove 315. In other words, when the clamping plate 312 is engaged with the locking block 331, the locking member 32 abuts against the clamping plate 312, thereby preventing the locking member 32 from shaking in the horizontal direction and improving the stability of the structure.

[0040] Specifically, in some embodiments, Figure 1 and 2 As shown, an elastic member 313 is further disposed within the positioning channel 311; one end of the elastic member 313 is connected to the clamping plate 312. That is, during assembly, the clamping block 331, while being inserted along the positioning channel 311 and engaging the clamping plate 312, compresses the elastic member 313, causing the clamping plate 312 to be compressed and contracted against the inner wall of the positioning member 31. Simultaneously, the locking member 32 abuts the clamping plate 312 and is threadedly assembled with the clamping block 331, thereby enhancing the stability of the structure.

[0041] Specifically, in some embodiments, Figure 1 and 5As shown, at least two limiting plates 22 are provided within the second channel 21, with a limiting inner cavity 23 defined between the limiting plates 22. A tightening member 33 is disposed within the limiting inner cavity 23, with the side ends of the tightening member 33 abutting against the side ends of the limiting plates 22. This structure, through the left and right limiting action of the limiting plates 22, reduces left and right movement of the tightening member 33, thereby improving the assembly stability between the tightening member 33 and the horizontal profile 2 and enhancing safety in use.

[0042] Specifically, in some embodiments, Figure 1 and 5 As shown, the horizontal profile 2 is also equipped with a bending block 24 that bends toward the second channel 21 (the middle limiting cavity 23); the bending block 24 abuts the top of the insertion component 33. This structure, through the left and right limiting effects of the limiting plate 22 on the insertion component 33, and the upper and lower limiting effects of the bending block 24 and the horizontal profile 2 on the insertion component 33, improves the assembly stability between the insertion component 33 and the horizontal profile 2, enhancing safety in use. The limiting cavity 23 is an inverted T-shaped limiting cavity, with the top of the inverted T-shaped limiting cavity extending through the top of the horizontal profile 2.

[0043] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0044] Based on the disclosure and teachings of the above description, those skilled in the art will be able to make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention fall within the scope of protection of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation on the present invention.
