Description

Technical Field

[0001] This utility model relates to the field of seat belts, and more particularly to a device for detecting the buckle of a speed difference fall arrestor. Background Technology

[0002] For any work performed at a height of 2 meters or more above the reference plane where a fall is possible, safety belts must be worn. High-altitude safety belts are personal protective equipment used to prevent falls by workers at heights. When working at heights, some work environments require climbing. To facilitate climbing, a differential fall arrestor is generally used. The main function of a differential fall arrestor is to quickly detect the falling speed of personnel or equipment. If the falling speed exceeds a set safety threshold, it will immediately activate a locking mechanism to quickly stop or slow the fall, thus protecting the workers at heights. When using a differential fall arrestor, hooks are not required, freeing the workers' hands for operation or climbing. However, many workers at heights, due to a lack of sufficient safety awareness or a sense of complacency, often fail to connect the differential fall arrestor to their safety belt, resulting in slips and falls, which pose a significant threat to their personal safety.

[0003] Therefore, there is an urgent need to develop an intelligent device that is fixed to the safety belt at one end and connected to the differential speed fall arrestor at the other end, and monitors the operator's use of the differential speed fall arrestor in real time to prevent accidents.

One end of the elastic component is connected to a movable plate, and the other end is connected to a mounting post, and is used to drive the movable component to abut against the detection component. The speed-differential fall arrester is connected to the movable component and drives the movable component away from the detection component. The speed-differential fall arrester includes a hook. The movable component abuts against or moves away from the detection component to detect whether the hook of the speed-differential fall arrester is hooked.

[0007] Furthermore, the first part is provided with a groove and a plurality of fixing posts. The groove includes a first end and a second end. The two ends of the fixing posts are respectively fixedly connected to the first end and the second end. The groove and the fixing posts form a closed-loop space so that the hook of the speed difference fall arrestor is tightly fastened to the closed-loop space.

[0008] Furthermore, the detection component includes a detection switch and a trigger plate. The trigger plate is movably connected to the detection switch. The trigger plate abuts against or moves away from the detection switch to cause the detection switch to output different detection results. The detection results are used to determine whether the speed difference fall arrestor is correctly fastened.

[0009] Furthermore, one end of the movable component moves within the closed-loop space, while the other end is located in front of the trigger plate. The hook of the speed differential fall arrester is attached to the movable component, which in turn moves the movable component away from the trigger plate, thereby moving the trigger plate away from the detection switch.

[0010] Furthermore, the movable component is provided with multiple first through holes, and the elastic component is provided with a first hook and a second hook at both ends respectively. The first hook is hung in the first through hole so that one end of the elastic component is connected to the movable plate, and the second hook is hung on the mounting post so that the other end of the elastic component is connected to the mounting post. The elastic component provides tension to the movable component and drives the movable component to abut against the trigger plate so that the trigger plate abuts against the detection switch.

[0011] Furthermore, the second part is provided with a plurality of mounting holes, and the mounting post is embedded in the mounting holes so that the top cover is fixedly connected to the second part.

[0012] Furthermore, the third part is provided with a second through hole, which is used to connect the rope body, and the rope body is used to connect the safety belt.

[0013] Furthermore, a power supply assembly is also provided above the second part. The power supply assembly includes a power source and a charging interface.

The hook of the speed difference fall arrestor is attached to the movable component 11, and the movable component 11 is moved away from the trigger plate 212. The trigger plate 212 abuts against or moves away from the detection switch 211, so that the detection switch 211 outputs different detection results.

[0026] This utility model proposes that when the hook of the speed difference fall arrestor is attached to the movable part 11, it moves the movable part 11 away from the detection part 21.

The detection element 21 is electrically connected to the circuit board 26. The detection element 21 includes a detection switch 211 and a trigger plate 212. One end of the trigger plate 212 is movably connected to the detection switch 211, and the other end is used to trigger the detection switch 211. The trigger plate 212 abuts against or moves away from the detection switch 211 so that the detection switch 211 outputs different detection results. The detection results are used to determine whether the speed difference fall arrestor is properly fastened. In a specific embodiment, when the trigger plate 212 abuts against the detection switch 211, the detection signal output by the detection switch 211 is "1", which represents the detection result that the speed difference fall arrestor is not fastened. When the trigger plate 212 moves away from the detection switch 211, the detection signal output by the detection switch 211 is "0", which represents the detection result that the speed difference fall arrestor is fastened.
