Description

Technical Field

[0001] This utility model relates to the field of safety belt technology, and in particular to a safety belt buckle for high-altitude operations. Background Technology

[0002] According to national standards, 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 heights, and the buckle, as the fastening component, plays a crucial role. However, existing mechanical buckles cannot monitor whether workers are fastening or securing their safety belts as required. Furthermore, the lack of effective supervision mechanisms at construction sites means that many workers at heights often misuse or fail to properly fasten their safety belts due to insufficient safety awareness, a sense of complacency, or negligence in the wearing process. This leads to slips, falls, and other dangerous accidents, posing a significant threat to the personal safety of workers at heights.

[0003] Therefore, there is an urgent need to develop intelligent buckles that can monitor operators in real time, so that operators can use the buckles correctly and avoid safety accidents. Utility Model Content

[0029] Please refer to Figures 2-4 The inlet end of the chamber 22 is provided with several elastic movable components 24. The elastic movable components 24 include a movable block 241, a cylinder 242 and an elastic element 243. The movable block 241 is provided with a through hole, and the cylinder 242 passes through the through hole and is fixedly connected to the housing 21 so that the movable block 241 can move at the inlet end.

[0030] In specific implementation: The elastic movable component 24 includes two components, which are located at the two ends of the inlet end of the chamber 22 respectively. The elastic movable component 24 includes a movable block 241, a cylinder 242 and an elastic element 243. The movable block 241 is provided with a through hole, and the cylinder 242 passes through the through hole. The two ends of the cylinder 242 are fixedly connected to the housing 21 respectively. The movable block 241 moves at the inlet end based on the cylinder 242. The locking tongue 11 is inserted and pulled out by pressing the movable block 241. When the locking tongue 11 is inserted or pulled out, the two movable blocks 241 move correspondingly. In a specific embodiment, when the locking tongue 11 is not inserted, the two movable blocks 241 are close together. When the locking tongue 11 is inserted into the chamber 22, the locking tongue 11 forces the two movable blocks 241 to separate, and the tongue lock is located between the two movable blocks 241. When the tongue lock is pulled out, the two movable blocks 241 return to close together.

[0031] Please refer to Figures 1-4 The elastic element 243 is a spring.

The locking tongue 11 includes a first part 111 and a second part 112. The width of the first part 111 is greater than the width of the second part 112. A groove 113 is formed at the connection between the first part 111 and the second part 112. When the locking tongue 11 is inserted into the cavity 22, the movable block 241 fits tightly with the groove 113 and is used to provide resistance to the locking tongue 11 so that the locking tongue 11 is locked in the cavity 22.

[0032] In specific implementation: the movable block 241 includes a first end 2411 and a second end 2412. The first end 2411 is located inside the cavity 22, and the second end 2412 is located outside the female buckle 2. The locking tongue 11 includes a first part 111 and a second part 112. The first part 111 is located at the front end of the second part 112, and the width of the first part 111 is greater than the width of the second part 112. A groove 113 is formed at the connection between the first part 111 and the second part 112 of the locking tongue 11. When the locking tongue 11 is inserted into the cavity 22, the first end 2411 of the movable block 241 fits tightly with the groove 113. One end of the elastic member 243 abuts against the inner side of the cavity 22, and the other end abuts against the first end 2411 of the movable block 241, and is used to provide support for the movable block 241. In one specific embodiment, the elastic element 243 is a spring. When the latch 11 is inserted into the chamber 22, the spring force provides a thrust to the movable block 241, causing the first end 2411 of the movable block 241 to tightly abut against the groove 113. The first end 2411 of the movable block 241 locks the first part 111 of the latch 11 into the chamber 22, thereby locking the latch 11 tightly into the chamber 22 and effectively improving the safety of the latch. When it is necessary to unlock the latch, it is only necessary to press the second ends 2412 of the two movable blocks 241 inward at the same time. The second ends 2412 of the movable blocks 241 drive the first ends 2411 of the two movable blocks 241 to separate, and the distance between the first ends 2411 of the two movable blocks 241 increases, so that the latch 11 can be pulled out, effectively improving convenience.

[0033] Please refer to Figures 1-4 The movable block 241 is provided with a convex surface 2413, and the convex surface 2413 is provided with a second detection element 2414. The convex surface 2413 abuts against the first part 111. The second detection element 2414 is used to detect the pressure value on the convex surface 2413 to determine the tightness of the seat belt.

[0034] In specific implementation: The first end 2411 of the movable block 241 is provided with a convex surface 2413, and the convex surface 2413 is provided with a second detection component. The convex surface 2413 of the first end 2411 of the movable block 241 abuts against the first part 111 of the locking tongue 11. The second detection component 2414 is used to detect the pressure value of the convex surface 2413 to determine the tightness of the safety belt. In a specific embodiment, when the safety belt is worn correctly, the male buckle 1 and the female buckle 2 are respectively pulled to both sides. At this time, the first part 111 of the locking tongue 11 will apply pressure to the convex surface 2413. The second detection component 2414 detects the pressure value. When the pressure value is less than the set value, the safety belt is worn too loosely and cannot play a sufficient safety protection role. When the pressure value is within the set pressure range, it indicates that the tightness of the safety belt is appropriate and effectively protects the safety of the workers.

One end of the charging interface 252 is electrically connected to the power supply 251, and the other end is connected to an external charging device and is used to charge the power supply 251. In a specific embodiment, the power supply 251 uses a battery, and the battery life algorithm is optimized to support a long battery life mode, effectively improving the usage time of the device. One end of the indicator light 27 is electrically connected to the power supply assembly 25, and the other end is located outside the housing 21, and is used to indicate the power supply status. Regarding the power supply status 251, in one specific embodiment, when the power supply 251 has sufficient power, the indicator light 27 displays green; when the power supply 251 has insufficient power, the indicator light displays red, which is beneficial for timely charging of the equipment. The wireless communication module is electrically connected to the circuit board 26 and is used to send the detection results of the first detection element 23 and the second detection element 2414 to the monitoring terminal, which is beneficial for real-time monitoring of whether the operators are using the buckles correctly. In one specific embodiment, the wireless communication module adopts 2.4G wireless communication, which effectively ensures timely data transmission.
