DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figures 1 to 7 A building railing skeleton connection structure shown includes:

[0029] A first railing frame 1 and a second railing frame 2, one end of the first railing frame 1 and one end of the second railing frame 2 are perpendicular to each other, a connecting piece 3 is provided between one end of the first railing frame 1 and one end of the second railing frame 2, and a connecting groove 4 is provided at both ends of the connecting piece 3, one end of the first railing frame 1 and one end of the second railing frame 2 extend into the two connecting grooves 4 respectively;

[0030] Two movable grooves 5, the two movable grooves 5 are respectively opened inside the top and bottom ends of the connecting member 3, the movable grooves 5 are connected to the two connecting grooves 4, a movable plate 6 is arranged inside the movable groove 5, and a limit block 7 is fixedly arranged inside both ends of the movable plate 6, and a circular limit groove 8 is opened at the top and bottom of one end of the first railing frame 1 and the second railing frame 2, and four limit blocks 7 are respectively arranged inside the four circular limit grooves 8;

[0031] An operating groove 9 is provided in the middle of the outer side of the connecting piece 3. A bidirectional screw 10 is rotatably connected inside the operating groove 9. Two ends of the bidirectional screw 10 respectively pass through the top and bottom ends inside the operating groove 9 and extend into the two movable grooves 5. Two ends of the bidirectional screw 10 respectively pass through the two movable plates 6. The bidirectional screw 10 is connected to the two movable plates 6 by threads and the threads are in opposite directions. A turntable 11 is fixedly provided at the outer end in the middle of the bidirectional screw 10. The turntable 11 is arranged inside the operating groove 9.

[0032] A blocking cover 12 is provided on the outside of the operating groove 9, and a limiting assembly is provided on the blocking cover 12. The limiting assembly includes two limiting plates 13 arranged on the outside of both ends of the connecting member 3. A square limiting groove 14 is opened at both ends of the blocking cover 12. One end of the two limiting plates 13 passes through the outside of both ends of the connecting member 3 and extends into the two square limiting grooves 14 respectively. A connecting plate 15 is fixedly provided at the other end of the limiting plate 13. The two connecting plates 15 are respectively arranged on the outside of the first railing frame 1 and the second railing frame 2. Two spring grooves 16 are opened on the outside of both ends of the connecting member 3. The two spring grooves 16 are respectively arranged at the top and bottom of the limiting plate 13. Springs 17 are fixedly provided inside the spring grooves 16. One ends of the two springs 17 are respectively fixedly connected to the inner sides of both ends of the connecting plate 15. A handle 18 is fixedly provided on the outside of the connecting plate 15.

In this way, one end of the first railing frame 1 and the second railing frame 2 can be fixed in the two connecting grooves 4, and then the first railing frame 1 and the second railing frame 2 are connected and fixed to the connecting piece 3.

[0034] The utility model adjusts the position of the movable plate 6 and the limit block 7 by rotating the bidirectional screw 10. The limit block 7 and the circular limit groove 8 can limit the first railing frame 1 and the second railing frame 2, so that the first railing frame 1 and the second railing frame 2 can be quickly limited and fixed inside the two connecting grooves 4 on the connecting piece 3, so that the connection between the first railing frame 1 and the second railing frame 2 is relatively simple and convenient, the connection efficiency is high, and the situation that the ends of the first railing frame 1 and the second railing frame 2 are damaged during the connection process is avoided. This embodiment specifically solves the problem that when the building protection railing frame is installed and connected, the connection at the turning point of the two railing frames is mostly fixed together by oblique insertion of screws, which is easy to damage the railing frame, and the connection process is not convenient and fast enough, and the installation and connection efficiency is low.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
