Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to a point-type curtain wall connection device. Background Art

[0002] Point-type curtain wall joints are widely used in the construction industry, primarily for connecting curtain wall materials such as glass panels to ensure the stability and safety of the curtain wall. Currently, common point-type curtain wall joints typically include components such as welded parts, joint claws, connectors, and joint heads.

[0003] However, existing point-type curtain wall joint systems present several issues during use. A major issue is that the joint is secured to the connector head via a hexagonal cap and nut. However, these caps and nuts are susceptible to thread slippage during use. This can lead to a loose joint, compromising the glass panel's securement and posing a safety hazard to the curtain wall.

[0004] This thread slippage problem will greatly reduce the stability of the curtain wall. In severe weather or during long-term use, the glass panels may loosen or even fall off, posing a serious threat to surrounding people and property.

[0005] To this end, we proposed a point-type curtain wall connection device. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6, A point - type curtain wall connecting device, including a welding part 1. A connecting claw 2 is arranged on the welding part 1. One end of the connecting claw 2 far from the welding part 1 is fixedly connected with a connecting head 3. A connecting joint 4 is arranged on the connecting head 3. On the connecting joint 4, a hexagonal sealing head cap 6, a hexagonal nut 7 and a tooth piece 5 are arranged in sequence from top to bottom. The connecting head 3 is located between the hexagonal sealing head cap 6 and the hexagonal nut 7. Connecting grooves 8 are opened on the upper and lower side walls of the connecting head 3 at positions corresponding to the hexagonal sealing head cap 6 and the hexagonal nut 7. The hexagonal sealing head cap 6 and the hexagonal nut 7 are respectively movably clamped inside the corresponding connecting grooves 8. A limiting mechanism is arranged on the connecting head 3 to limit the positions of the hexagonal sealing head cap 6 and the hexagonal nut 7.

[0029] The limiting mechanism includes a first T - shaped sliding groove 9, a first T - shaped sliding block 10, a linkage block 14 and a top block 15. A first T - shaped sliding groove 9 is opened on the outer wall surface of the connecting head 3. A first T - shaped sliding block 10 is movably clamped inside the first T - shaped sliding groove 9. The first T - shaped sliding groove 9 is an arc groove of a semi - circle, and the first T - shaped sliding block 10 is an arc block of a quarter - circle. Two linkage blocks 14 are symmetrically arranged up and down on the outer wall surface of the connecting head 3 at positions corresponding to the first T - shaped sliding groove 9. One ends of the two linkage blocks 14 close to each other correspond to the opening position of the first T - shaped sliding groove 9. One ends of the two linkage blocks 14 far from each other are fixedly connected with a top block 15 respectively. The two top blocks 15 are respectively located inside the corresponding connecting grooves 8.

[0030] During use, the glass plate can be clamped and fixed through the connecting joint 4 and the tooth piece 5, and the hexagonal sealing head cap 6 and the hexagonal nut 7 can fix the connecting joint 4 on the connecting head 3. Since one ends of the two linkage blocks 14 close to each other correspond to the opening position of the first T - shaped sliding groove 9, when the first T - shaped sliding block 10 slides inside the first T - shaped sliding groove 9 to the positions of the two linkage blocks 14, the first T - shaped sliding block 10 will push the two linkage blocks 14 apart, making the two linkage blocks 14 move towards the side far from each other. At this time, the top block 15 will enter the inside of the corresponding connecting groove 8 under the drive of the linkage block 14, and the top block 15 contacts the outside of the corresponding hexagonal sealing head cap 6 or hexagonal nut 7. In this way, the top block 15 can limit the position of the hexagonal sealing head cap 6 or the hexagonal nut 7 to avoid the problem of thread slipping during use.

[0031] Both the linkage block 14 and the top block 15 are L - shaped blocks. Second clamping grooves 13 are opened on the upper and lower side walls of the connecting head 3 at positions corresponding to the two linkage blocks 14. The horizontal ends of the linkage blocks 14 are movably clamped inside the corresponding second clamping grooves 13. On the side wall of the inside of the connecting groove 8 far from the corresponding top block 15, a first clamping groove 12 is opened at a position corresponding to the top block 15. The position of the first clamping groove 12 inside the connecting groove 8 is located outside the hexagonal sealing head cap 6 or the hexagonal nut 7. The horizontal ends of the top blocks 15 are movably clamped inside the first clamping grooves 12.

[0032] When the top block 15 is located inside the first card slot 12, the hexagonal head cap 6 or the hexagonal nut 7 will not contact the vertical end on the top block 15 when rotating inside the corresponding connection slot 8.

[0033] On the outer wall surface of the connector 3, two second T-shaped sliding grooves 16 are provided corresponding to the positions of the two linkage blocks 14. Inside both of the two second T-shaped sliding grooves 16, a second T-shaped slider 17 is movably clamped. The side wall surface of the second T-shaped slider 17 away from the connector 3 is fixedly connected to the corresponding point on the vertical end of the linkage block 14. The side wall surface of the second T-shaped slider 17 away from the first T-shaped sliding groove 9 is fixedly connected to a spring 18. The end of the spring 18 away from the second T-shaped slider 17 is fixedly connected to the adjacent wall surface inside the second T-shaped sliding groove 16.

[0034] The linkage block १४ is movably clamped to the connector 3 through the second T-shaped slider 17. And when the first T-shaped slider 10 pushes the two linkage blocks 14 apart, at this time the spring 18 is deformed by force. When the first T-shaped slider 10 resets, the two linkage blocks 14 will reset under the action of the elastic force of the spring 18.

[0035] The side wall surfaces of the vertical ends of the two linkage blocks 14 close to each other are arc surfaces. The setting of the arc surfaces on the linkage blocks 14 can facilitate the first T-shaped slider 10 to push up the linkage blocks 14 when moving.

[0036] Limit grooves 11 are symmetrically provided on the upper and lower side wall surfaces of the first T-shaped slider 10. The internal shape and size of the limit grooves 11 are adapted to the shape and size of the linkage blocks 14. After the first T-shaped slider 10 pushes the two linkage blocks 14 apart, continue to move the first T-shaped slider 10 so that the position of the limit grooves 11 on the first T-shaped slider 10 corresponds to the linkage blocks 14. The end of the linkage block 14 close to the limit groove 11 is movably clamped inside the corresponding limit groove 11. At this time, while being able to limit the position of the linkage block 14, the linkage block 14 can also limit the position of the first T-shaped slider 10 through the limit grooves 11.

[0037] Working principle:

[0038] After the installation is completed and the hexagonal head cap 6 and the hexagonal nut 7 are tightened, rotate the first T-shaped slider 10 inside the first T-shaped sliding groove 9 so that the first T-shaped slider 10 pushes the two linkage blocks 14 apart. The top block 15 moves to the inside of the corresponding connection slot 8 under the drive of the linkage block 14. And at this time, the outer wall surface of the top block 15 contacts the outer wall surface of the tightened hexagonal head cap 6 or the hexagonal nut 7. In this way, the limiting effect on the hexagonal head cap 6 and the hexagonal nut 7 is achieved, avoiding the problem that they are affected by the outside during use and causing thread slipping, resulting in insecure fixation and potential safety hazards.

[0039] The provision of the arc-shaped surface on the linkage block 14 facilitates the first T-shaped slider 10 to lift the linkage block 14 during movement, with a simple, convenient and practical structure.

[0040] After the first T-shaped slider 10 pushes the two linkage blocks 14 apart and continues to move the first T-shaped slider 10 until the position of the limiting groove 11 on the first T-shaped slider 10 corresponds to the linkage block 14, one end of the linkage block 14 close to the limiting groove 11 is movably clamped inside the corresponding limiting groove 11. At this time, while being able to limit the position of the linkage block 14, the linkage block 14 can also limit the position of the first T-shaped slider 10 through the limiting groove 11, ensuring the stability of the limiting effect when the device is in use.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
