Threaded holes 10 are opened in the middle of the two sides of the fixed bracket 1, and the fixing bolts 8 are threadedly connected in the threaded holes 10;
[0029] A limit component 4. The limit component 4 is arranged at one end of the fixed bracket 1 away from the buckle 5. The telescopic bracket 2 is prevented from falling off the fixed bracket 1 through the limit component 4. The telescopic bracket 2 slidably penetrates through the limit component 4. The limit component 4 includes a housing 41. The housing 41 is fixedly connected to the end of the fixed bracket 1. A through hole is opened along the reverse direction of the inner cavity length in the middle of the housing 41. The size of the through hole is smaller than the size of the inner cavity. An anti-drop block 7 is fixedly connected to the end of the telescopic bracket 2, and the anti-drop block 7 is slidably arranged in the inner cavity;
[0030] During operation, first unfold the device. By pulling the telescopic bracket 2 outwards, the telescopic bracket 2 can be pulled out from the inner cavity of the fixed bracket 1. The telescopic bracket 2 is limited by the limit component 4 and will not fall off the fixed bracket 1. Thus, the device can be extended, making the two fixed brackets 1 form a 90-degree angle. Fix the diagonal brace 3 on the fixed bracket 1 through the fixing bolts 8, so that the diagonal brace 3 and the two-side fixed brackets 1 form a stable triangular safety loop, and the roof stable fulcrum (the roof stable fulcrum can be a steel structure frame or a fixed column, a fixed pipe, etc. structure) is surrounded in the middle of the triangular safety loop. Furthermore, an installation anchor point can be formed, and the buckle 5 is connected to the safety belt on the staff through a protection cable, which can effectively prevent the staff from falling; in addition, the main body of the device is an A-shaped bracket. When the operator moves during roof operation, the anti-fall bracket moves along. Due to structural reasons, the size of the roof hole and the daylighting belt is smaller than the longest hypotenuse size of the A-shaped bracket. In case of an accident, the bracket will get stuck on the roof hole, preventing the person from falling directly; when not in use, the diagonal brace 3 can be removed, and then the two-side fixed brackets 1 and the telescopic brackets 2 can be folded to reduce the occupied space and facilitate storage and transportation; in addition, the device has a simple structure, a wide application range, is light and reliable, and can be mass-produced and used.
[0031] A sliding cavity 48 is formed in the inner wall of the housing 41. A moving block 45 is slidably installed in the sliding cavity 48. A limiting block 44 is fixedly connected to the side wall of the moving block 45 close to the telescopic bracket 2. A groove 42 is formed in the middle of the side of the telescopic bracket 2 close to the moving block 45. A plurality of groups of limiting grooves 43 are uniformly arranged at the innermost side of the groove 42. The limiting grooves 43 are adapted to the insertion blocks. One side of the moving block 45 away from the groove 42 is fixedly connected to a pull rod 46. The pull rod 46 penetrates through a through hole 49 formed in the housing 41. A return spring 47 is installed in the through hole 49. The return spring 47 is sleeved on the pull rod 46. A fixing frame 410 is fixedly connected to the outer wall of the housing 41. The end of the return spring 47 abuts against the inner side of the fixing frame 410. The pull rod 46 slidably penetrates through the fixing frame 410. During operation, first, the moving block 45 and the limiting block 44 are pulled outwards, the return spring 47 is compressed, the bottom of the limiting block 44 disengages from the limiting groove 43, and then the telescopic bracket 2 is pulled outwards. Then, the return spring 47 pushes the moving block 45 and the limiting block 44 to reset and be inserted into the limiting groove 43, preventing the telescopic bracket 2 from moving back, thereby fixing the position of the telescopic bracket 2 and making the telescopic bracket 2 stable. In addition, the extension length of the telescopic bracket 2 can be controlled to meet more usage requirements and has a wider application range.
[0032] A slow-down protector 6 is movably installed on the buckle 5 through a spring buckle one. The other end of the slow-down protector 6 is fixedly installed with a spring buckle two. During operation, the slow-down protector 6 is essentially a pulley block structure and can only pay out the wire at a fixed rate. The slow-down protector 6 is fixedly connected to the safety belt on the staff through the internal protection cable and the spring buckle two. When the operator falls, the A-shaped bracket can catch the falling point, and the operator can descend slowly at a stable rate until reaching the ground through the slow-down protection cable without the need for rescue by others, preventing secondary risks.
[0033] The anti-detachment block 7 is a rectangular block, and the side of the anti-detachment block 7 is attached to the inner wall of the inner cavity. During operation, the movement range of the anti-detachment block 7 is restricted, so that the telescopic bracket 2 is stably installed in the inner cavity of the fixed bracket 1.
[0034] A chamfer is arranged at the bottom of the limiting block 44. During operation, it is convenient for the limiting block 44 to be quickly inserted into the limiting groove 43.
[0035] The side wall of the moving block 45 is attached to the inner wall of the sliding cavity 48. During operation, the movement direction of the moving block 45 is restricted, so that the limiting block 44 can be accurately inserted into the limiting groove 43.
[0036] Embodiment 2
[0037] Please refer to Figure 3 As shown, compared with Embodiment 1, as another implementation manner of the present invention.
