[0024] Furthermore, the connecting groove 21 includes a first step groove 211 close to one end of the opening, and the other end of the first step groove 211 is provided with a second step groove 212 which is connected to the first step groove 211 and has a width smaller than the first step groove 211. The second step groove 212 is provided with a through hole for allowing part of the bolt body to pass through on the bottom wall away from the first step groove 211, and the bolt head part of the bolt is clamped by the first step groove 211 to limit the bolt.

[0025] Furthermore, an elastic member 52 is provided between the locking block 5 and the glass curtain wall 3, and a side wall at one end of the elastic member 52 abuts against the bottom wall of the locking block 5, and an opposite side wall at the other end abuts against the bottom wall at one end outside the connecting groove 21, so as to play a buffering role when locking the glass curtain wall 3.

[0026] Furthermore, the cross beam 2 is perpendicular to the longitudinal beam 1 , the cross beam 2 is fixed to the side end of the longitudinal beam 1 , and a connector 22 is provided at the connection between the cross beam 2 and the longitudinal beam 1 , and the connector 22 is used to connect the cross beams 2 on both sides of the longitudinal beam 1 to each other, so as to expand the connection structure of the glass curtain wall 3 .

[0027] Furthermore, first grooves 23 are provided at the upper and lower ends of the end surface of the cross beam 2 close to the glass curtain wall 3 . The first grooves 23 are used to fix the first buffer pad 7 to play a buffering role.

[0028] Furthermore, the bottom wall of the locking block 5 is provided with second grooves 53 at the upper and lower ends, and a second buffer pad 8 is installed in the second groove 53 to isolate the hard contact between the locking block 5 and the glass curtain wall 3 and play a buffering role.

[0029] Furthermore, a decorative cover 6 is provided on the outer side of the locking block 5 , and the decorative cover 6 can be snap-connected to the locking block 5 .

When the glass curtain wall 3 and the locking block 5 come into contact during the adjustment process, the elastic member 52 between the two begins to work, and the elastic member 52 can buffer the impact and reduce vibration. To avoid damage or stress concentration that may be caused by direct rigid contact, the elastic member 52 can be a hard rubber pad or a compressible spring inserted into the bolt body; the crossbeam 2 and the longitudinal beam 1 are perpendicular to each other and are tightly connected by the connecting member 22 to form a stable frame structure. This frame provides a stable support for the glass curtain wall 3 to ensure that it will not be displaced or deformed due to external forces. The first buffer pad 7 and the second buffer pad 8 are installed on the crossbeam 2 and the locking block 5 through the first groove 23 and the second groove 53 respectively to reduce the hard friction and collision between the crossbeam 2, the locking block 5 and the glass curtain wall 3. A decorative cover is provided on the outer side of the locking block 5 to improve the overall aesthetics of the curtain wall and protect the locking block 5 from erosion by the external environment. The glass curtain wall 3 is a double-layer glass structure, and a sealing pad 4 is provided at the edge of the opposite end of the double-layer glass structure to improve the sealing and thermal insulation performance between the double-layer glass.

[0032] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
