Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction ropes, specifically to a conductive structure of a traction rope for an emergency unlocking device. Background Technology
[0002] An anti-lost leash is a safety product typically used to prevent young children or pets from getting lost or having accidents in public places. Anti-lost leashes are generally made of plastic or other durable materials, are retractable, and have a wristband at each end. These wristbands are worn on the wrists of adults and children respectively, or attached to the pet, to maintain contact within a certain distance. This design can effectively prevent young children or pets from getting lost. With technological advancements, to prevent the leash between adults and toddlers / pets from disengaging in emergencies, anti-lost leashes have evolved into automatically release leashes. These leashes consist of a main control box, a controlled box, and a leash connecting the main control box and the controlled box. The controlled box has an automatically unlocking latch, which the main control box can control to automatically unlock. Typically, a wire is installed inside the leash to establish an electrical connection between the main control box and the controlled box. The two ends of the wire are directly soldered to the control circuit boards in the main control box and the controlled box, respectively. However, because the leash is fixedly connected to both the main control box and the controlled box, and the leash often twists during use, the wire also twists. Over time, the wire joints may break, rendering the main control box and the controlled box uncontrollable. Utility Model Content
[0003] This utility model provides a conductive structure for the traction rope of an emergency unlocking device, the main purpose of which is to overcome the above-mentioned problems existing in the prior art.
[0004] This utility model is achieved using the following technical solution:
[0005] A conductive structure for a traction rope of an emergency unlocking device includes a traction rope, two fixing seats, and two POGO PIN adapter circuit boards. Both ends of the traction rope are connected to rotating heads. Each fixing seat and POGO PIN adapter circuit board corresponds to one rotating head. Each fixing seat has a rotating hole, and the end of each rotating head is located within the rotating hole and can rotate around it. Two wires are arranged along the length of the traction rope. A conductive plate is provided at the end of each rotating head. The end face of the conductive plate has two inner and outer conductive rings, each connected to one of the two wires. The POGO PIN adapter circuit board has two POGO PIN pins, each corresponding to and abutting against one of the conductive rings. The two fixing seats are respectively fixed inside a main control box and a controlled box, and the two POGO PIN adapter circuit boards are also respectively fixed inside the main control box and the controlled box.
[0006] Furthermore, a steel rope is also provided inside the traction rope along its length.
[0007] Furthermore, the outer circumferential surface of the end of the rotating head is provided with a positioning groove, the fixed seat is provided with a screw hole communicating with the rotating hole, a set screw is provided in the screw hole, and the top of the set screw is adapted to the positioning groove and located in the positioning groove.
[0008] Furthermore, the end face of the rotating head is provided with a placement groove adapted to the conductive plate, and the conductive plate is located in the placement groove.
[0009] Furthermore, the inner wall of the placement groove is provided with a limiting protrusion, and the outer peripheral surface of the conductive plate is provided with a limiting groove that matches the limiting protrusion, with the limiting protrusion located inside the limiting groove.
[0010] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following advantages: This utility model has a novel structure and ingenious design. The two fixing seats are respectively fixed inside the main control box and the controlled box, and the two POGO PIN adapter circuit boards are also respectively fixed inside the main control box and the controlled box. The rotating heads at both ends of the traction rope can rotate around the corresponding fixing seats. When the two ends of the traction rope rotate, the two POGO PIN pins on the POGO PIN adapter circuit board still abut against the corresponding conductive rings, and the main control box and the controlled box are always electrically connected. When the traction rope of this utility model twists during use, the wire, rotating head, and conductive plate twist synchronously with the traction rope. Furthermore, the wire connector is not directly connected to the control circuit board in the main control box or the control circuit board in the controlled box, but is connected to the conductive plate. Therefore, when the traction rope twists during use, the wire connector will not be broken. Attached Figure Description

[0015] Reference Figures 1 to 3A conductive structure for a traction rope of an emergency unlocking device includes a traction rope 1, two fixing seats 2, and two POGO PIN adapter circuit boards 3. Both ends of the traction rope 1 are connected to rotating heads 4. Each fixing seat 2 and POGO PIN adapter circuit board 3 corresponds to one rotating head 4. Each fixing seat 2 has a rotating hole 21, and the end of each rotating head 4 is located within the rotating hole 21 and can rotate around it. Two wires, wire 5 and wire 6, are arranged along the length of the traction rope 1. A conductive plate 7 is provided at the end of each rotating head 4. The end face of the conductive plate 7 has two conductive rings, one inside the other, namely a conductive ring 71 and a conductive coil 72. The conductive ring 71 and the conductive coil 72 are connected to wire 5 and wire 6, respectively. The POGO PIN adapter circuit board 3 has two POGO PINs, POGO PIN 31 and POGO PIN 32. Each POGO PIN corresponds to and abuts against a conductive coil. Specifically, POGO PIN 31 corresponds to and abuts against conductive coil 71, and POGO PIN 32 corresponds to and abuts against conductive coil 72. The two mounting bases 2 are respectively fixed inside the main control box and the controlled box, and the two POGO PIN adapter circuit boards 3 are also respectively fixed inside the main control box 9 and the controlled box 10.
[0016] Reference Figure 3 The traction rope 1 is further provided with a steel rope 8 along its length. The steel rope 8 can ensure the tensile strength of the traction rope 1 and prevent the conductors 5 and 6 from being broken. In this embodiment, the traction rope 1 is a non-extendable traction rope.
[0017] Reference Figure 2 and Figure 3 The outer circumferential surface of the end of the rotating head 4 is provided with a positioning groove 41. The fixing base 2 is provided with a screw hole 22 communicating with the rotating hole 21. A set screw 23 is provided in the screw hole 22. The top of the set screw 23 is adapted to the positioning groove 41 and is located in the positioning groove 41. The end of the rotating head 4 is installed in the rotating hole 21, and the top of the set screw 23 is located in the positioning groove 41, so that the end of the rotating head 4 cannot be disengaged from the rotating hole 21 while being able to rotate around the rotating hole 21.
[0018] Reference Figure 2 and Figure 3The end face of the rotating head 4 is provided with a placement groove 42 adapted to the conductive plate 7, and the conductive plate 7 is located in the placement groove 42. The inner wall of the placement groove 42 is provided with a limiting protrusion 43, and the outer peripheral surface of the conductive plate 7 is provided with a limiting groove 73 adapted to the limiting protrusion 43. The limiting protrusion 43 is located in the limiting groove 73, and the conductive plate 7 is tightly installed in the placement groove 42. The cooperation of the limiting protrusion 43 and the limiting groove 73 ensures that the rotating head 4 and the conductive plate 7 will not shift, and the rotating head 4 and the conductive plate 7 can rotate synchronously.
[0019] Reference Figures 1 to 4 The design principle of this utility model is as follows: The two fixing seats 2 are respectively fixed inside the main control box 9 and the controlled box 10. The two POGO PIN adapter circuit boards 3 are also respectively fixed inside the main control box 9 and the controlled box 10. The POGO PIN adapter circuit board 3 located in the main control box 9 is electrically connected to the control circuit board of the main control box 9. The POGO PIN adapter circuit board 3 located in the controlled box 10 is electrically connected to the unlocking mechanism of the drive latch 12 to automatically unlock inside the controlled box 10. The main control box 9 and the controlled box 10 are existing structures, and their specific structures will not be described in detail here. The rotating heads 4 at both ends of the traction rope 1 can rotate around the corresponding fixing seats 2. When the two ends of the traction rope 1 rotate, the POGO PIN pins 31 and POGO PIN pins 32 on the POGO PIN adapter circuit board 3 still abut against the corresponding conductive coils 71 and 72. The main control box 9 and the controlled box 10 are always electrically connected. When the traction rope 4 of this utility model twists during use, the wires 5 and 6, the rotating head 4 and the conductive plate 7 twist synchronously with the traction rope 1. The joints of the wires 5 and 6 are not directly connected to the control circuit board in the main control box 9 and the unlocking mechanism in the controlled box 10, but are connected to the conductive plate 7. Therefore, when the traction rope 1 twists during use, the joints of the wires 5 and 6 will not be broken.
[0020] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
