Description

Technical Field

[0001] The utility model relates to the technical field of signal transmission connecting wires, in particular to a retractable signal transmission connecting wire. Background Art

[0002] Transmission cables, also called transmission lines or delay lines, are cables that form a loop with two conductors of a certain length. The main function of transmission cables is to transmit signals from one device to another to achieve data transmission and communication. Common examples include cables, optical fibers, network cables, etc. During signal transmission, transmission lines need to consider the impact of signal propagation and assume that each point along the transmission line has a different potential when the signal is transmitted. Among them, scalability is an important function of signal transmission cables.

[0003] For example, the Chinese patent "A new type of high-speed signal transmission connection line" with announcement number CN215771779U includes a cable and a plug, the cable includes a core center conductor and a core ground wire, the core center conductor has a core center conductor inside, the core center conductor and the core ground wire are provided with a cable shielding layer outside, the cable shielding layer is covered with a cable insulation layer outside, the plug includes a plug shell and a plug internal module located inside the plug shell, the plug internal module has a plurality of welding positions for welding with the core center conductor, a plurality of core center conductors are welded to a plurality of welding positions one by one, the exposed portion of the core center conductor and the outside of the welding position are covered with an insulating inner mold, the plug shell, the insulating inner mold, the core center conductor, the core ground wire and the cable shielding layer are injection molded with a conductive inner mold outside, and the conductive inner mold is electrically connected to the core ground wire and the metal part of the plug shell.

[0004] Although the above-mentioned prior art can realize the use of signal transmission connecting lines, in actual use, on the one hand, the signal transmission connecting lines are prone to aging when left exposed. When the signal transmission connecting lines are not in use, they are directly left exposed, resulting in the signal transmission connecting lines being exposed to the outside for a long time and being eroded by the natural environment such as sunlight, rain, oxygen, dust, etc., thereby shortening the service life of the signal transmission connecting lines. On the other hand, the signal transmission connecting lines are not convenient enough to be retracted and retracted. The operator performs auxiliary operations when the signal transmission connecting lines are retracted and retracted, resulting in a cumbersome process each time the signal transmission connecting lines are retracted and retracted, thereby increasing the workload of the operator. Therefore, it does not meet the existing needs. In this regard, we propose a retractable signal transmission connecting line. Utility Model Content

[0005] The utility model aims to provide a retractable signal transmission connection line to solve the problems in the above background technology that the signal transmission connection line is easily aged when exposed and the signal transmission connection line is not convenient when retracted.

[0006] To achieve the above object, the utility model provides the following technical solution: a retractable signal transmission connection line, comprising a base, a retractable box is fixedly arranged on the upper end of the base; and further comprising:

[0007] A rotating rod is arranged inside the telescopic box, and the rotating rod is rotatably connected to the inner wall of the telescopic box, the upper and lower ends of the outer side of the rotating rod are both provided with rotating disks, and the rotating disk is fixedly connected to the rotating rod, and the outer side of the rotating rod located between the rotating disks is provided with a winding drum, and the winding drum is fixedly connected to the rotating rod;

[0008] A vortex spring is arranged at one end of the rotating disk close to the side wall of the telescopic box, one end of the vortex spring is fixedly connected to the rotating rod, and the other end of the vortex spring is fixedly connected to the rotating disk.

[0009] Preferably, a plurality of fixed teeth are fixedly provided on the outside of the rotating disk, and the fixed teeth are distributed in an annular shape with equal spacing.

[0010] Preferably, a mounting plate is provided on one side inside the telescopic box, and three limiting teeth are fixedly provided on the upper and lower ends of one side of the mounting plate, the limiting teeth are equidistantly distributed, and the limiting teeth are meshed and connected with the fixed teeth.

[0011] Preferably, a mounting frame is fixedly provided on one side of the outside of the telescopic box, a pull rod is provided on one side of the cross plate of the mounting frame, the pull rod is slidably connected to the mounting frame, and one end of the pull rod extends into the interior of the telescopic box and is fixedly connected to the mounting plate.

[0012] Preferably, a return spring is fixedly provided at the front and rear ends of the upper and lower ends on the other side of the mounting plate, and the other end of the return spring is fixedly connected to the telescopic box.

[0013] Preferably, a connecting wire body is provided outside the winding drum, one end of the connecting wire body is fixedly connected to the winding drum, and the other end of the connecting wire body extends to the outside of the telescopic box, and a telescopic ring is fixedly provided outside the connecting wire body outside the telescopic box.

[0014] Preferably, a signal transmission line is provided at the upper end of the telescopic box, and one end of the signal transmission line extends into the interior of the telescopic box and communicates with the connecting line body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can make the extension and retraction of the connecting wire body more convenient through the take-up drum and the vortex spring. When the connecting wire body is extended, the connecting wire body located outside the telescopic box is pulled, and the connecting wire body is separated from the take-up drum by the pulling force and extends outward. At the same time, the rotating disk rotates when the connecting wire body extends outward. When the rotating disk rotates, the vortex spring is in a compressed state. When the connecting wire body is used up, the fixation of one end of the connecting wire body is released, and the vortex spring is reset. The force generated during the resetting process of the vortex spring drives the rotating disk to rotate together with the take-up drum. When the take-up drum rotates, the connecting wire body is rolled up and wrapped around the outside thereof, so that the connecting wire body is automatically rolled up into the telescopic box when not in use, making the extension and retraction of the connecting wire body more convenient while also preventing the connecting wire body from being exposed to the environment for a long time when not in use.

[0017] When the limit tooth is disengaged from the fixed tooth, the rotating disk continues to rotate clockwise to rewind the connecting wire body onto the reel, so that the length of the connecting wire body can be adjusted while the connecting wire body is extended and retracted.

[0018] 3. The utility model is provided with a telescopic ring, which can improve the bending resistance of the connecting wire body. When the connecting wire body is connected, the connection between the connecting wire body and the telescopic box will inevitably bend. After the connecting wire body is bent and used many times, the surface of the connecting wire body will be damaged. The telescopic ring can be extended and retracted when the connecting wire body is bent and connected, avoiding the situation where the surface of the connecting wire body is damaged and the wire is exposed due to long-term bending when the connecting wire body is connected, thereby extending the service life of the connecting wire body.

[0028] When in use, the connecting wire body 7 is extended, and the connecting wire body 7 located outside the telescopic box 2 is pulled. The connecting wire body 7 is detached from the winding drum 5 by the pulling force and extends outward. At the same time, the rotating disk 4 rotates when the connecting wire body 7 extends outward. When the rotating disk 4 rotates, the vortex spring 15 is in a compressed state. When the connecting wire body 7 is used up, the fixation of one end of the connecting wire body 7 is released, and the vortex spring 15 is reset. The force generated during the resetting process of the vortex spring 15 drives the rotating disk 4 to rotate together with the winding drum 5. When the winding drum 5 rotates, the connecting wire body 7 is rolled up and wrapped around its outside, so that the connecting wire body 7 is automatically rolled up into the telescopic box 2 when not in use.

[0029] See also Figure 1 and Figure 2 A plurality of fixed teeth 6 are fixedly arranged on the outside of the rotating disk 4 , and the fixed teeth 6 are distributed in a ring shape with equal spacing, so that the rotating position of the rotating disk 4 can be adjusted by the fixed teeth 6 .

The limiting teeth 9 are equidistantly distributed, and the limiting teeth 9 are meshed and connected with the fixed teeth 6, so that the rotating disk 4 can be clamped and fixed through the cooperation of the limiting teeth 9 and the fixed teeth 6.

[0031] See also Figure 1 and Figure 2 A mounting frame 13 is fixedly provided on one side of the outside of the telescopic box 2, and a pull rod 12 is provided on one side of the cross plate of the mounting frame 13. The pull rod 12 is slidably connected to the mounting frame 13, and one end of the pull rod 12 extends to the inside of the telescopic box 2 and is fixedly connected to the mounting plate 10, so that the mounting plate 10 can be driven to move by the pull rod 12.

[0032] See also Figure 1 and Figure 4 The front and rear ends of the upper and lower ends on the other side of the mounting plate 10 are fixedly provided with a return spring 11, and the other end of the return spring 11 is fixedly connected to the telescopic box 2, so that the mounting plate 10 can be driven to reset by the return spring 11.

[0033] See also Figure 1 and Figure 2 A connecting wire body 7 is provided on the outside of the winding drum 5, one end of the connecting wire body 7 is fixedly connected to the winding drum 5, and the other end of the connecting wire body 7 extends to the outside of the telescopic box 2, and a telescopic ring 8 is fixedly provided on the outside of the connecting wire body 7 located outside the telescopic box 2, so as to protect the connecting wire body 7 when it is bent through the telescopic ring 8.

[0034] See also Figure 1 A signal transmission line 14 is provided at the upper end of the telescopic box 2, and one end of the signal transmission line 14 extends to the interior of the telescopic box 2 and is connected to the connecting line body 7, so as to facilitate connection with the connecting line body 7 through the signal transmission line 14.

When the connecting wire body 7 is extended to a suitable length, the vortex spring 15 drives the limiting teeth 9 on the rotating disk 4 to rotate clockwise through the force generated by the reset. When the limiting teeth 9 rotate clockwise, they are fixed with the fixed teeth 6 to fix the rotating disk 4 and limit the connecting wire body 7 to a suitable length. When the connecting wire body 7 is retracted after use, At this time, pull the pull rod 12 outward, and the installation plate 10 is driven by the pull rod 12 to move together with the limit tooth 9 and disengage the limit tooth 9 from the fixed tooth 6. When the limit tooth 9 is disengaged from the fixed tooth 6, the rotating disk 4 continues to rotate clockwise to rewind the connecting wire body 7 onto the reel 5. When the connecting wire body 7 is connected, the connection between the connecting wire body 7 and the telescopic box 2 will inevitably bend. After the connecting wire body 7 is bent and used many times, the surface of the connecting wire body 7 will be damaged. The telescopic ring 8 provided can be telescoped when the connecting wire body 7 is bent and connected.
