AI Technical Summary
The buckles are prone to loosening or coming loose in the complex external force environment of the construction site, which reduces the stability of the fall arrest device.
A limiting mechanism is set on the outside of the clamping plate, including a mounting block, a screw, a limiting block and a rubber pad. The screw pushes the limiting block to fit against the buckle surface, and the rubber pad increases friction and the spring provides pre-tightening force to prevent the buckle from disengaging from the screw.
It effectively prevents the buckle from loosening due to external vibration or impact, thus improving the stability and reliability of the fall arrestor.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of fall protection devices, and in particular to a fall protection device used in building curtain wall construction. Background Technology
[0002] A building curtain wall refers to the non-load-bearing exterior wall cladding of a building, typically composed of panels (glass, metal, stone, ceramic, etc.) and a supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.). A building curtain wall construction fall arrestor is a safety device specifically designed to prevent construction workers or tools from falling from heights during the installation of a building curtain wall. This fall arrestor incorporates the following technologies:
[0003] 1. Hanging rings: Fall arrestors have hanging rings for connecting the safety rope and safety belt;
[0004] 2. Braking mechanism: The braking mechanism includes metal clips. The shape and surface treatment (such as surface texture) of the clips are designed to quickly and firmly clamp the rope when it is under stress.
[0005] 3. Rope channel: The self-locking device has a dedicated rope channel inside to ensure that the rope can properly interact with the braking mechanism and other components when passing through.
[0006] 4. The outer shell clamps are closed again, the rope is clamped between the clamps, and then the screws are screwed back into the threaded holes and tightened. The elastic buckle automatically engages with the screws to prevent them from loosening.
[0007] Clips typically rely solely on their elastic structure to connect with screws. This connection method is prone to loosening or even detachment when faced with complex external forces at construction sites, such as equipment shaking caused by strong winds or collisions during construction. Once the connection between the clip and the screw is broken, the clamping plate is only connected by the screw, which reduces the stability of the fall arrestor. This application proposes a solution to this problem: a limiting mechanism is installed on the outside of the clamping plate to restrict the movement of the clip, preventing the clip from being disconnected from the screw due to external vibration, shaking, or accidental collision, thus ensuring the stability of the fall arrestor. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a fall arrest device for building curtain wall construction. It solves the technical problem that buckles usually rely solely on their own elastic structure and screw connection. This connection method is prone to loosening or even falling off when facing complex external force environments at the construction site, such as equipment shaking caused by strong winds or collisions during construction. Once the connection between the buckle and the screw is broken, the clamp is only connected by the screw, which leads to a decrease in the stability of the fall arrest device.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A fall arrestor for building curtain wall construction includes a clamping plate. The clamping plate has a limiting mechanism on its exterior to restrict the movement of the buckle. The limiting mechanism includes a mounting block, a threaded hole, a screw, a limiting block, and a rubber pad. The mounting block is fixedly installed on the exterior of the clamping plate. The threaded hole is opened on the exterior of the mounting block. The screw is threadedly connected to the interior of the threaded hole. The limiting block is rotatably connected to the exterior of the screw. The rubber pad is fixedly installed on the exterior of the limiting block. A guide groove is opened on the exterior of the clamping plate. The end of the limiting block away from the rubber pad is slidably connected to the interior of the guide groove.
[0011] The limiting block has a rotating hole on its outside, and a limiting shaft is rotatably connected inside the rotating hole. The limiting shaft is fixedly installed on the outside of the screw. A cylindrical helical spring is fixedly connected inside the guide groove and is fixedly installed on the upper surface of the limiting block. A guide shaft is fixedly installed inside the guide groove. The limiting block has a through hole for movement on its outside. The cylindrical helical spring is movably sleeved on the outside of the guide shaft. The limiting block is slidably connected to the outside of the guide shaft through the through hole.
[0012] Preferably, the guide groove is slidably connected to a sealing plate for shielding the cylindrical helical spring, and the sealing plate is fixedly installed on the outside of the limiting block.
[0013] Preferably, the screw is provided with a rotating mechanism for rotating the screw. The rotating mechanism includes a groove, a rotating shaft and a handle. The groove is opened on the outside of the screw, the rotating shaft is rotatably connected to the inside of the groove, and the handle is fixedly connected to the outside of the rotating shaft.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. By setting a limit block and cooperating with the screw, after the buckle and screw are engaged, the screw is rotated to push the limit block downward until the rubber pad is attached to the outside of the buckle. At this time, the screw cannot be rotated, and the outer rubber pad of the limit block is attached to the surface of the buckle. The buckle is restricted by the limit block and cannot be pressed, preventing the buckle from being disconnected from the screw due to external vibration, shaking or accidental collision, thus ensuring the stability of the fall protection device.
[0016] 2. By setting a handle and cooperating with the mounting block, when the rubber pad is attached to the outside of the buckle, turn the handle downwards so that one end of the handle is attached to the outside of the mounting block. At this time, the screw cannot be rotated, preventing the screw 4 from rotating accidentally when the position of the limit block does not need to be adjusted. Attached Figure Description

[0023] This application provides a fall arrest device for building curtain wall construction, which effectively solves the technical problem that buckles usually rely solely on their own elastic structure and screw connection. In the face of complex external force environment at the construction site, such as equipment shaking caused by strong winds or collisions during construction, the buckles are prone to loosening or even falling off. Once the connection between the buckle and the screw is broken, the clamp 1 is only connected by the screw, which leads to a decrease in the stability of the fall arrest device.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that buckles typically rely solely on their own elastic structure and screw connection. This connection method is prone to loosening or even detachment when facing complex external forces at construction sites, such as equipment shaking caused by strong winds or collisions during construction. Once the connection between the buckle and the screw is broken, the clamping plate 1 is only connected by the screw, leading to a decrease in the stability of the fall arrestor. The overall approach is as follows:
[0026] To address the problems existing in the prior art, this utility model provides a fall arrest device for building curtain wall construction, including a clamping plate 1. A limiting mechanism for restricting the movement of the buckle is provided on the outside of the clamping plate 1. The limiting mechanism includes a mounting block 2, a threaded hole 3, a screw 4, a limiting block 5, and a rubber pad 6. The mounting block 2 is fixedly installed on the outside of the clamping plate 1. The threaded hole 3 is located on the outside of the mounting block 2. The screw 4 is threaded into the inside of the threaded hole 3. The limiting block 5 is rotatably connected to the outside of the screw 4. The rubber pad 6 is fixedly installed on the outside of the limiting block 5. The device has a guide groove 7. The end of the limiting block 5 away from the rubber pad 6 is slidably connected inside the guide groove 7. By setting the limiting block 5 and cooperating with the screw 4, when the buckle is engaged with the screw, the screw 4 is rotated to push the limiting block 5 downward until the rubber pad 6 is attached to the outside of the buckle. At this time, the screw 4 cannot be rotated. The outer rubber pad 6 of the limiting block 5 is attached to the surface of the buckle. The buckle is restricted by the limiting block 5 and cannot be pressed, preventing the buckle from being disengaged from the screw due to external vibration, shaking or accidental collision, thus ensuring the stability of the fall protection device.
[0027] The limiting block 5 has a rotating hole 8 on its outside, and a limiting shaft 9 is rotatably connected inside the rotating hole 8. The limiting shaft 9 is fixedly installed on the outside of the screw 4.
[0028] A cylindrical helical spring 10 is fixedly connected inside the guide groove 7. The cylindrical helical spring 10 is fixedly installed on the upper surface of the limiting block 5. A guide shaft 11 is fixedly installed inside the guide groove 7. A through hole 12 for movement is opened on the outside of the limiting block 5. The cylindrical helical spring 10 is movably sleeved on the outside of the guide shaft 11. The limiting block 5 is slidably connected to the outside of the guide shaft 11 through the through hole 12.
[0029] The guide groove 7 is slidably connected to a closing plate 13 for shielding the cylindrical helical spring 10. The closing plate 13 is fixedly installed on the outside of the limiting block 5.
[0030] The screw 4 is provided with a rotating mechanism for rotating the screw 4. The rotating mechanism includes a groove 14, a rotating shaft 15 and a handle 16. The groove 14 is opened on the outside of the screw 4. The rotating shaft 15 is rotatably connected to the inside of the groove 14. The handle 16 is fixedly connected to the outside of the rotating shaft 15. The handle 16 is T-shaped.
[0031] The screw 4, through its engagement with the threaded hole 3, can push the limit block 5 to move when it rotates. It is the key driving component for realizing the limit function. The position of the limit block 5 is adjusted by rotating the screw 4. The guide groove 7 is opened on the outside of the clamping plate 1 to guide the linear movement of the limit block 5, ensuring that the limit block 5 will not deviate during the movement, thus ensuring the accuracy and reliability of the limit function.
[0032] The rubber pad 6 is fixed to the outside of the limiting block 5. When the limiting block 5 presses against the buckle, the rubber pad 6 can increase the friction between the limiting block 5 and the buckle, while avoiding damage to the buckle surface.
[0033] The screw 4 is connected to the rotating hole 8 through the limiting shaft 9, which ensures that the screw 4 pushes the limiting block 5;
[0034] When the limiting block 5 is attached to the outside of the buckle, the cylindrical helical spring 10 returns to its original position. At this time, the cylindrical helical spring 10 will apply a downward elastic force to the limiting block 5. This elastic force can be used as a pre-tightening force to enhance the limiting effect of the limiting block 5 on the buckle. Even when subjected to some minor vibration or external force interference, this pre-tightening force can help the limiting block 5 stay in its original position better.
[0035] The cylindrical helical spring 10 is movably sleeved on the outside of the guide shaft 11, ensuring that the cylindrical helical spring 10 can deform along the correct axial direction during compression and reset. When the limit block 5 moves up and down, the cylindrical helical spring 10 will not twist or deflect.
[0036] The sealing plate 13 is slidably connected to the outside of the guide groove 7 to shield the cylindrical helical spring 10 and prevent external impurities from entering the guide groove 7 and affecting the normal operation of the cylindrical helical spring 10.
[0037] The handle 16 is fixed to the outside of the rotating shaft 15 for easy rotation of the screw 4. The handle 16 is designed in a T-shape for easy gripping and force application by the operator.
[0038] Working principle:
[0039] First, rotate handle 16 upwards to make it stand upright. Hold handle 16 and rotate screw 4. Screw 4 pushes limit block 5 downwards. During this process, limit block 5 moves inside guide groove 7, ensuring linear movement of limit block 5. When screw 4 can no longer rotate, the outer rubber pad 6 of limit block 5 is attached to the surface of buckle. At this time, buckle is restricted by limit block 5 and cannot be pressed.
[0040] The second step is to rotate the handle 16 downwards so that it fits against the outside of the mounting block 2. At this point, the screw 4 cannot rotate, preventing accidental rotation when the position of the limiting block 5 does not need to be adjusted. Finally, it should be noted that the above embodiments are merely examples to clearly illustrate the present invention and are not intended to limit the implementation. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
