[0028] See also Figures 1 to 6 The utility model provides a technical solution: a profile connection structure, including: a connection structure body 1, a profile 2 is arranged at the lower side of the connection structure body 1, a movable block 3 is installed on one side of the profile 2, a claw 4 is fixedly connected to the top of the movable block 3, a mounting groove 9 is opened on one side of the profile 2, a fixed shell 10 is fixedly installed in the mounting groove 9, a rectangular groove 11 is opened on one side of the fixed shell 10, a track block 24 is fixedly connected to one side of the inner wall of the fixed shell 10, a first slide groove 12 is opened on the other side of the fixed shell 10, and a clamping groove 13 is opened on one side of the first slide groove 12. A second sliding groove 14 is provided on one side of the slot 13, the movable block 3 is slidably connected to the fixed shell 10, a limit block 15 is fixedly connected to one side of the movable block 3, the limit block 15 is slidably connected to the rectangular groove 11, a pressing block 16 is movably sleeved in the movable block 3, the pressing block 16 is slidably connected to the inner wall of the movable block 3, a clamping rod 17 is fixedly connected to one end of the pressing block 16, the clamping rod 17 is slidably connected to the first sliding groove 12, the slot 13, and the second sliding groove 14, a spring 18 is abutted against the bottom of the pressing block 16, and the bottom of the spring 18 is fixedly connected to the fixed shell 10.

[0029] First, insert the limit rod 23 into the connecting plate 19, which is a slightly deformable material. By inserting the block 5 into the claw 4, the connecting plate 19 is moved downward, thereby driving the block 5 to move downward. The block 5 will press the claw 4 to move downward. The claw 4 is also a slightly deformable material, so that the claw 4 contracts inward under the constraint of the fixed shell 10, and then the claw 4 clamps the block 5. While the claw 4 and the block 5 move downward, the movable block 3 is in the rectangular groove 11 through the limit block 15 on one side thereof. The movable block 3 slides downward, thereby causing the movable block 3 to drive the pressure block 16 installed therein to press downward. One end of the pressure block 16 is fixedly connected to a clamping rod 17. Under the limiting constraint of the track block 24, the clamping rod 17 slides into the first slide groove 12 while compressing the spring 18, and then under the reverse elastic force of the spring 18, one end of the clamping rod 17 enters the clamping groove 13. At this time, the upper surface of the connecting plate 19 abuts against the upper surface of the profile 2, thereby completing the fixed connection between the clamping block 5 and the clamping claw 4.

[0030] A clamping block 5 is arranged on the upper side of the clamping claw 4, a profile 2 6 is arranged on one side of the clamping block 5, a fixing sleeve 7 is installed on both sides of the profile 2 6, a locking sleeve 8 is arranged on the upper side of the fixing sleeve 7, a connecting plate 19 is fixedly connected to the top of the clamping block 5, grooves 20 are provided on both sides of the profile 2 6, a limiting hole 21 is provided on one side of the connecting plate 19 and passes through the groove 20, the fixing sleeve 7 is fixedly installed in the groove 20, a fastening clip 22 is fixedly clamped in the fixing sleeve 7, the upper side of the fastening clip 22 is sleeved in the locking sleeve 8, the locking sleeve 8 and the fixing sleeve 7 are threadedly connected, a limiting rod 23 is sleeved in the fastening clip 22, and the bottom of the limiting rod 23 is sleeved in the connecting plate 19.

[0031] After the claw 4 is fixedly connected with the clamping block 5, one end of the profile 2 6 is abutted against the upper surface of the profile 1 2, and the top of the limiting rod 23 is inserted into the limiting hole 21 in the groove 20. At this time, part of the limiting rod 23 is also inserted into the fastening clamp 22. By twisting the locking sleeve 8, due to the threaded cooperation between the locking sleeve 8 and the fixing sleeve 7, the locking sleeve 8 will continue to descend, and the four forks of the fastening clamp 22 all have conical surfaces, and their conical surfaces are continuously matched with the inner conical surface of the bottom of the locking sleeve 8, so that the fastening clamp 22 is continuously tightened, and then the limiting rod 23 is locked, and finally the connection between the profile 2 6 and the profile 1 2 is completed.

[0032] In actual use, first insert the limit rod 23 into the connecting plate 19, insert the card block 5 into the claw 4, and move the connecting plate 19 downward, thereby driving the card block 5 to move downward, and the card block 5 will press the claw 4 to move downward. The claw 4 is also made of a slightly deformable material, so that the claw 4 contracts inwardly under the constraint of the fixed shell 10, and then the claw 4 clamps the card block 5. While the claw 4 and the card block 5 move downward, the movable block 3 slides in the rectangular groove 11 through the limit block 15 on one side thereof, so that the movable block 3 slides downward, so that the movable block 3 drives the pressure block 16 installed in the sleeve therein to press downward, and one end of the pressure block 16 is fixedly connected to the card rod 17, under the limiting constraint of the track block 24, the card rod 17 slides into the first slide groove 12 while compressing the spring 18, and then under the reverse elastic force of the spring 18, one end of the card rod 17 enters the card groove 13, at this time, the upper surface of the connecting plate 19 abuts against the upper surface of the profile 1 2, thereby completing the fixed connection between the card block 5 and the claw 4. After the fixed connection between the claw 4 and the card block 5, one end of the profile 2 6 abuts against the upper surface of the profile 1 2, and the top of the limiting rod 23 is inserted into the limiting hole 21 in the groove 20. At this time, part of the limiting rod 23 is also inserted into the fastening clip 22. By twisting the locking sleeve 8, due to the locking sleeve 8 and There is a threaded fit between the fixing sleeves 7, the locking sleeve 8 will continue to drop, and the four forks of the fastening clamp 22 are all with conical surfaces, and the conical surfaces are continuously matched with the inner conical surface of the bottom of the locking sleeve 8, so that the fastening clamp 22 is continuously tightened, and then the limiting rod 23 is locked, and finally the connection between the profile 2 6 and the profile 1 2 is completed. When it is necessary to disassemble the profile 1 2 and the profile 2 6, first rotate the locking sleeve 8 in the opposite direction to unlock the limiting rod 23 of the fastening clamp 22, pull the profile 2 6 upward to disengage it from the limiting rod 23, and then press the connecting plate 19 downward. Because the connecting plate 19 can be slightly deformed, pressing the connecting plate 19 downward will bring The movable block 5 moves downward, so that the clamping rod 17 slides into the second slide groove 14 under the limiting action of the track block 24, and slides out of the second slide groove 14 under the reverse elastic force of the spring 18. While sliding out, the clamping claw 4 pushes the clamping block 5 out, and the clamping claw 4 extends out of the fixed shell 10 and opens, no longer clamping the clamping block 5, so that the clamping block 5 is disassembled, and then the overall disassembly is completed, avoiding direct connection with angle aluminum and self-tapping screws, loose structure, and inconvenient installation. When using angle aluminum to fix profiles or welding to make doors and windows, the screws will be exposed, which is easy to scratch the users of the doors and windows, and is not beautiful. At the same time, it can also be disassembled and installed many times and used repeatedly.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
