Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-altitude power maintenance technology, specifically to an automatic detection type safety belt attachment point. Background Technology
[0002] When outdoor electrical equipment needs maintenance, since the equipment is often located at high altitudes, it is necessary to use the lifting platform of the engineering vehicle to send the operators to the designated height. Because it is a high-altitude operation, the operators need to wear safety belts. However, in actual operation, it often happens that the operators fail to fasten their safety belts, which poses a great safety hazard. Therefore, it is particularly important to design an automatic detection safety belt attachment point to solve the above problems. Summary of the Invention
[0003] To address the aforementioned problems, this invention designs an automatic detection seatbelt attachment point. A proximity switch is installed at one end of the mounting bracket. This switch detects whether a seatbelt is missing and monitors the connection between the seatbelt loop and its connector in real time. This design significantly reduces safety hazards and enhances practicality.
[0004] To solve the above-mentioned technical problems, this utility model provides an automatic detection type seat belt attachment point, characterized in that it includes a fixed frame, a hanging ring connector, a seat belt, a seat belt hanging ring, and a proximity switch. The fixed frame is part of an engineering vehicle lifting platform. The hanging ring connector is L-shaped, with a connection hole matching the seat belt hanging ring on one end face. The other end of the hanging ring connector is fixed to the side wall of the upper end of the fixed frame by welding or bolting. One end of the seat belt is connected to the hanging ring connector through the mating of the seat belt hanging ring and the connection hole. The proximity switch is detachably installed on the top of the fixed frame and directly opposite the seat belt hanging ring.
[0005] Furthermore: the proximity switch is mounted on the top of the mounting bracket via a sensor mounting base. The sensor mounting base is detachably connected to the mounting bracket. The sensor mounting base has a through mounting hole, and the proximity switch is detachably mounted in the mounting hole.
[0006] Furthermore: the upper surface of the fixing frame is a concave structure, and the upper end of the proximity switch extends out of the sensor mounting base and faces the seat belt loop.
[0007] With the above structure, this utility model has a proximity switch at one end of the fixing frame. The proximity switch can detect whether the seat belt is not fastened and monitor the connection between the seat belt loop and the loop connector in real time. This design greatly reduces safety hazards. In addition, this design also has the advantages of simple structure, easy manufacturing and practical efficiency. Attached Figure Description
[0008] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0009] Figure 1 This is a top-view perspective view of the present invention.
[0010] Figure 2 This is a bottom-view perspective structural diagram of the present invention.
[0011] In the diagram: 1 is the mounting bracket, 2 is the safety belt, 3 is the safety belt loop, 4 is the loop connector, 5 is the proximity switch, and 6 is the sensor mounting base. Detailed Implementation
[0012] like Figure 1 An automatic detection seatbelt attachment point is shown, comprising a fixing frame 1, a hook-and-loop connector 4, a seatbelt 2, a seatbelt hook-and-loop 3, and a proximity switch 5. The fixing frame is part of an engineering vehicle lifting platform. The hook-and-loop connector is L-shaped, with a connection hole matching the seatbelt hook-and-loop on one end. The other end of the connector is fixed to the upper side wall of the fixing frame by welding or bolting. One end of the seatbelt is connected to the hook-and-loop connector via the seatbelt hook-and-loop and the connection hole. The proximity switch is detachably mounted on the top of the fixing frame, directly opposite the seatbelt hook-and-loop. This invention features a proximity switch at one end of the fixing frame, which can detect whether the seatbelt is not fastened and monitor the connection between the seatbelt hook-and-loop connector in real time. When a missed fastening or other emergencies are detected, a sensor electrically connected to the proximity switch can activate an alarm and warning light to provide a reminder. This design greatly reduces safety hazards. Furthermore, this design has the advantages of simple structure, ease of manufacture, and high efficiency.
[0013] like Figure 1 and Figure 2 The proximity switch shown is mounted on top of a mounting bracket via a sensor mounting base 6. The sensor mounting base is detachably connected to the mounting bracket, and its interior has a through-hole. The proximity switch is detachably mounted within this hole. The upper surface of the mounting bracket is concave, with the upper end of the proximity switch extending beyond the sensor mounting base and facing the seatbelt loop. This design allows the proximity switch to be removed independently in case of malfunction, while the sensor mounting base can continue to be used, thus increasing its practicality.
[0014] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
