Technical Field

[0001] This utility model relates to the field of seat belt technology, and in particular to a seat belt hook buckle detection device. Background Technology

[0002] Safety belts must be worn for any work performed at a height of 2 meters or more above the reference plane where a fall is possible. Safety belts are personal protective equipment used to prevent falls by workers at height. The hook, as the connector between the safety belt and the safety cable, plays a crucial role. However, existing mechanical hook structures cannot monitor whether workers are correctly connecting the hook to the safety cable as required. Furthermore, the lack of effective supervision mechanisms at construction sites means that many workers at height often misuse the hook due to insufficient safety awareness, a sense of complacency, or negligence in the wearing process, leading to slips, falls, and other dangerous accidents. This poses a significant threat to the personal safety of workers at height.

[0035] Please refer to Figures 1-6 Each movable component 22 is equipped with a contact block 221. The number and position of the contact blocks 221 correspond to the number and position of the detection switches 211. When the hook is correctly hooked onto the safety cable, the movable component 22 moves inward toward the mounting groove 11, and the contact block 221 continuously presses against the trigger 212. The trigger 212 continuously moves closer to the circuit board 21, and the detection switch 211 outputs a signal indicating that the hook is correctly hooked. When the hook is not hooked onto the safety cable, the contact block 221 moves away from the trigger 212, and the trigger 212 moves away from the circuit board 21. The detection switch 211 outputs a signal indicating that the hook is not used. The signal of the buckle; when the hook is used incorrectly in the "high operation, low suspension" manner, the hook is in a semi-suspended state, and the hook and the safety steel cable are sometimes squeezed and sometimes not squeezed. The contact block 221 and the trigger 212 are randomly squeezed or moved away from each other, and the trigger 212 is randomly moved closer or further away from the circuit board 21.

[0036] In specific implementation: Each movable component 22 is provided with a contact block 221. The number and position of the contact blocks 221 correspond to the number and position of the detection switches 211. When the hook is correctly hooked onto the safety cable, the hook has a downward force due to its own weight. The movable component 22 is squeezed against the safety cable, and the safety cable provides an upward support force for the movable component 22. The support force drives the movable component 22 to move towards the circuit board 21. The contact blocks 221 on the movable component 22 continuously squeeze the inclined surface 213, causing the trigger 212 to move upward and closer to the circuit board 21. The detection switch 211 outputs a signal indicating correct hooking. In one specific embodiment, when the hook is correctly hooked onto the safety cable, the detection switch 211 continuously outputs an electrical signal "1". When the hook is not hooked onto the safety cable, the contact blocks 221 move away from the inclined surface 213, and the trigger 212 moves away from the circuit board 21. Switch 211 outputs a signal indicating that the hook is not in use. In one specific embodiment, when the hook is not attached to the safety cable, the detection switch 211 continuously outputs an electrical signal of "0". When the hook is incorrectly used in a "high-work, low-hook" manner, due to the upward pull of the safety belt, the hook is in a semi-suspended state, and the hook and safety cable are sometimes pressed and sometimes not. The contact block 221 and the inclined surface 213 are randomly pressed or moved away, and the trigger 212 is randomly moved closer or further away from the circuit board 21. The detection switch 211 outputs a signal indicating incorrect use. In one specific embodiment, when the hook is incorrectly used in a "high-work, low-hook" manner, the detection switch 211 outputs an electrical signal that changes irregularly between "1" and "0" for a period of time. The signal output by the detection switch 211 can effectively monitor whether the hook is attached or upside down, effectively ensuring the personal safety of the workers and avoiding the occurrence of safety accidents.
