[0034] Embodiment 2

[0035] Reference Figure 2-Figure 6A new type of connecting device, the limiting mechanism includes a second slide groove 15, a second limiting plate 16, a connecting rod 17, a second spring 18 and a first clamping groove 19, the inner sides of the wall connecting rod 1 and the connecting steel pipe 3 near one end of the rotating plate 2 are provided with a second slide groove 15, the inner sides of the two second slide grooves 15 are slidably connected with the second limiting plates 16, a connecting rod 17 is fixed on the top of the two second limiting plates 16, and a second spring 18 is fixed on the top of the two second limiting plates 16. The two second springs 18 are respectively located inside the wall connecting rod 1 and the connecting steel pipe 3, and a plurality of first clamping grooves 19 are evenly distributed on the inner side of the outer side of the rotating plate 2. The connecting rod 17 is clamped with the rotating plate 2 through the first clamping groove 19. The rotating plate 2 can be restricted by the design of the limiting mechanism, which can effectively prevent the rotating plate 2 from being accidentally rotated and affecting the use effect of the connecting piece.

[0036] A plurality of second clamping grooves 20 are evenly distributed on the inner side of the fixed steel pipe 4, and the two clamping blocks 12 are clamped with the fixed steel pipe 4 through the second clamping grooves 20. The opening of the second clamping grooves 20 is conducive to the clamping of the clamping blocks 12 and the fixed steel pipe 4, and convenient for adjusting the extension distance of the fixed steel pipe 4; first springs 13 are fixed to the tops of both ends of the clamping blocks 12, and the tops of the two first springs 13 are fixed to the connecting steel pipe 3. The first springs 13 are designed to help the clamping blocks 12 rebound, and one end of the lower fastener 5 and the upper fastener 6 are tightly connected by fixing screws 21 and nuts 22, and the fixing screws 21 are threadedly connected to the nuts 22. Through the cooperation of the fixing screws 21 and the nuts 22, the external frame uprights 7 can be firmly fixed between the lower fasteners 5 and the upper fasteners 6.

[0037] The use process of the novel connection device provided by the utility model is as follows: when pouring the building wall, the threaded sleeve 23 is installed on the wall, and then the threaded sleeve 23 is installed inside the wall by pouring cement, and the end of the wall connecting rod 1 connected to the connecting rod 17 is connected to the threaded sleeve 23, and the fixed steel pipe 4 is sleeved with the connecting steel pipe 3, so that the fixed steel pipe 4 extends to a suitable length, so that the clamping block 12 is aligned with the second clamping groove 20;

[0038] Pull the connecting rod 17 upwards. Since the second limiting plate 16 is fixedly connected to the connecting rod 17, the movement of the connecting rod 17 drives the second limiting plate 16 to move, so that the second spring 18 fixed to the second limiting plate 16 is compressed by the second limiting plate 16. As the connecting rod 17 moves, the connecting rod 17 is no longer engaged with the first engaging groove 19, so that the rotating plate 2 can move and rotate. Since one end of the wall connecting rod 1 is mounted on the wall, the wall connecting rod 1 cannot rotate at this time. Since the wall connecting rod 1 and the rotating plate 2 are connected by the connecting rod 17, the connecting steel pipe 3 cannot rotate at this time.

[0039] Since the rotating threaded rod 8 is fixedly connected to the rotating plate 2, the rotation of the rotating plate 2 drives the rotating threaded rod 8 to rotate, so that the movable plate 10 threadably connected to the rotating threaded rod 8 also moves. Since the movable plate 10 is fixed to the first limiting plate 11 and the first limiting plate 11 is clamped with the first sliding groove 9, the movable plate 10 moves to one end under the rotation of the rotating threaded rod 8. The movable movable plate 10 squeezes the two clamping blocks 12 through the inclined surface 14. The clamping blocks 12 move out through the second clamping groove 20, so that the fixed steel pipe 4 is fixed to the connecting steel pipe 3. When the movable plate 10 is reset, the clamping blocks 12 rebound and are collected into the inside of the connecting steel pipe 3 with the help of the first spring 13.

[0040] The design of the adjustment mechanism makes it easy to install and remove the connection device, and the extension length of the fixed steel pipe 4 can be adjusted, so that the connection device can be flexibly adjusted according to the actual construction situation, without the need to frequently replace connection devices of different specifications, which can ensure the close fit between the connection device and the external wall and the supporting structure, reduce gaps and looseness, which helps to improve the stability and safety of the entire external wall system and prevent safety hazards caused by loose connections;

[0041] Place the external frame pole 7 on the lower fastener 5 and rotate the upper fastener 6, pass the fixing screw 21 through the lower fastener 5 and the upper fastener 6, and insert the nut 22 from the bottom end of the fixing screw 21 so that the fixing screw 21 is threadedly connected with the nut 22, thereby making the lower fastener 5 and the upper fastener 6 tightly buckled, so that the external frame pole 7 is fixed between the lower fastener 5 and the upper fastener 6.
