[0022] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0023] The following describes in detail, with reference to the accompanying drawings, a quick-locking connection structure for splicing aluminum profiles according to an embodiment of the present invention.

[0024] Example 1

[0025] For easier understanding, please refer to Figures 1 to 4 An embodiment of the quick-locking connection structure for splicing aluminum profiles provided by this utility model includes a first profile 1 and a second profile 2. Both the first profile 1 and the second profile 2 have an opening 3 at one end, and a docking fixing component is provided between the first profile 1 and the second profile 2.

[0026] The docking and fixing assembly includes a central shaft 401, a rotating shaft 402, two driving bevel gears 403, two fixing arms 404, a fixing screw 405, a driven bevel gear 406, fixing blocks 407, a first fixing hole 408, two second fixing holes 409, and an internal hexagonal slot 410. The central shaft 401 is disposed between the first profile 1 and the second profile 2. The rotating shaft 402 is rotatably connected to the middle of the central shaft 401. The two driving bevel gears 403 are fixedly installed on the outer wall of the rotating shaft 402. One end of each of the two fixing arms 404 is rotatably connected to the upper and lower ends of the central shaft 401, respectively. The fixing screw 405 is rotatably connected to the middle of the fixing arm 404. The driven bevel gear 406 is fixedly installed on one end of the fixing screw 405. The fixing blocks 407 are respectively... The first fixing hole 408 is located on one side of the fixing block 407, and the second fixing hole 409 is located on one end of the fixing block 407. The internal hexagonal groove 410 is located on the top of the rotating shaft 402. The two driving bevel gears 403 are located at the top and bottom of the central shaft 401, respectively. The driving bevel gear 403 meshes with the driven bevel gear 406. The shape of the fixing block 407 matches the inner shape of the first profile 1 and the second profile 2. The two fixing blocks 407 are fixedly installed inside one end of the first profile 1 and the second profile 2 by bolts threadedly connecting to the first fixing hole 408. The second fixing hole 409 is a threaded hole, and the fixing screw 405 is threadedly connected to the second fixing hole 409.

[0027] It should be noted that by setting two fixing arms 404 installed at the upper and lower ends of the central shaft 401, the fixing arms 404 can rotate freely. During installation, the docking angle of the first profile 1 and the second profile 2 is first determined by cutting, and the required opening 3 is opened at one end. Using the cooperation of the two fixing arms 404, which are equipped with fixing screws 405 and can rotate freely on the central shaft 401, and two fixing blocks 407, after the fixing angle of the profile is determined, the fixing blocks 407 are installed into the inside of the interface end of the first profile 1 and the second profile 2 respectively. At this time, one end of the fixing screw 405 is aligned with the second fixing hole 409. Then, the rotating shaft 402 is rotated by using a hex wrench and the internal hex socket 410. Then, the fixing screw 405 is rotated through gear transmission, so that the fixing screw 405 meshes with the second fixing hole 409, tightening the first profile 1 and the second profile 2, so that the first profile 1 and the second profile 2 are docked, which facilitates the connection and fixing of various angles.

[0028] Example 2

[0029] In some embodiments, such as Figure 2 As shown, one of the second fixing holes 409 is at the same height as one end of the fixing screw 405 located at the top of the central shaft 401, and the other second fixing hole 409 is at the same height as one end of the fixing screw 405 located at the bottom of the central shaft 401.

[0030] It should be noted that by opening two second fixing holes 409 on a fixing block 407, and the two second fixing holes 409 being at the same height as one end of the two fixing screws 405 respectively, there is no need to distinguish left and right when connecting them, which facilitates the connection between the fixing screws 405 and the two fixing blocks 407.

[0031] Working principle: In use, first cut and determine the mating angle of the first profile 1 and the second profile 2, and open the required hole 3 at one end. Utilize the cooperation of two fixing arms 404 with fixing screws 405 installed and able to rotate freely on the central shaft 401, and two fixing blocks 407. After the fixing angle of the profile is determined, install the fixing blocks 407 into the interior of the interface end of the first profile 1 and the second profile 2 respectively. At this time, align one end of the fixing screw 405 with the second fixing hole 409. Then, use a hex wrench and the internal hex socket 410 to rotate the rotating shaft 402. Then, through gear transmission, drive the fixing screw 405 to rotate, so that the fixing screw 405 meshes with the second fixing hole 409, tightening the first profile 1 and the second profile 2, so that the first profile 1 and the second profile 2 are mated, which facilitates connection and fixing at various angles.
