Description

Technical Field

[0001] This utility model relates to the field of automotive equipment technology, and in particular to a cold-resistant power cord for an easy-to-manage automotive cigarette lighter. Background Technology

[0002] A cigarette lighter is a common automotive accessory, primarily used to light cigarettes for car owners. When the cigarette lighter is pressed in, the heating element comes into contact with the bimetallic strip in the cigarette lighter socket, activating the circuit and heating the resistance wire to a temperature sufficient for combustion, allowing the user to light the cigarette.

[0003] In existing technologies, when cold-resistant power cords are collected together, they cannot be secured, causing them to loosen. This can lead to damage to the insulation layer of the power cords caused by shaking during vehicle operation, increasing the risk of short circuits. Short circuits may also cause sparks or even fires, resulting in high safety hazards and limited practicality. Therefore, we propose a cold-resistant power cord for car cigarette lighters that is easy to organize to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a cold-resistant power cord for car cigarette lighters that is easy to manage, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cold-resistant power cord for an easy-to-manage car cigarette lighter includes: a collection box, a rotating shaft rotatably mounted inside the collection box, a collection roller fixedly mounted on the outside of the rotating shaft, a power cord body wound around the outside of the collection roller, two rotating shafts rotatably mounted inside the collection box, worm gear segments fixedly mounted on the outside of each of the two rotating shafts, worm wheels meshing on the outside of each of the two worm gear segments, threaded rods fixedly mounted inside each of the two worm wheels, threaded cylinders threadedly connected to the outside of each of the two threaded rods, movable plates fixedly mounted on the ends of the two threaded cylinders that are close to each other, and fixed plates fixedly mounted on the sides of the two movable plates that are close to each other.

[0006] Preferably, a fixed plate is fixedly installed on the outer side of the rotating shaft, and multiple insertion holes are opened on the outer side of the fixed plate. A fixed block is fixedly installed on the front side of the collection box, and an insertion rod is slidably connected inside the fixed block. A fixed ring is fixedly installed on the outer side of the insertion rod, and a return spring is fixedly connected to the top of the fixed ring. The top of the return spring is fixedly connected to the bottom of the fixed block, and the bottom end of the insertion rod is movably inserted into the corresponding insertion hole.

[0007] Preferably, a first handwheel is fixedly installed on the front side of the rotating shaft, a second handwheel is fixedly connected to one end of one of the rotating shafts, and a synchronous pulley is fixedly installed on the outer side of both rotating shafts, with the same synchronous belt sleeved between the two synchronous pulleys.

[0008] Preferably, four T-shaped sliders are fixedly installed on the outer sides of both movable plates, and eight T-shaped grooves are opened on the inner side of the collection box, with the outer sides of the eight T-shaped sliders slidably connected to the corresponding T-shaped grooves.

[0009] Preferably, the ends of the two threaded rods that are far apart from each other are rotatably mounted on the inner side of the top wall and the inner side of the bottom wall of the collection box, respectively. The upper worm segment meshes with the rear side of the upper worm wheel, and the lower worm segment meshes with the front side of the lower worm wheel.

[0010] Preferably, a collection hole is provided on one side of the collection box, and an annular wear-resistant pad is fixedly installed in the collection hole. The outer side of the power cord body is slidably connected to the inside of the annular wear-resistant pad.

[0011] In this utility model, a cold-resistant power cord for an easy-to-manage car cigarette lighter is described. By pulling the plug rod, the plug rod is disengaged from the insertion hole, thus removing the plug rod from the fixing plate. Then, the No. 1 handwheel is turned, which drives the rotating shaft to rotate, further driving the collecting roller to rotate, so that the collecting roller collects the power cord body. After the power cord body is collected, the plug rod is released, and the plug rod is reinserted into the insertion hole under the action of the return spring, so that the plug rod is fixed to the fixing plate again, preventing the collecting roller from continuing to rotate. In this utility model, a cold-resistant power cord for an easy-to-manage car cigarette lighter is described. Rotating the second handwheel drives a rotating shaft, which in turn drives a synchronous pulley. Simultaneously, the synchronous pulley's rotation, via a synchronous belt, causes both rotating shafts to rotate. These two shafts then drive two worm gear segments, which in turn drive their meshing worm wheels. These worm wheels, in turn, drive two threaded rods, which in turn move threaded cylinders connected to them. Furthermore, the threaded cylinders drive two moving plates, causing two fixed plates to move closer together and secure the power cord body wound around the outside of the collecting roller. This prevents the power cord body from loosening, thus preventing damage to the insulation layer of the power cord body from shaking during vehicle operation, reducing the risk of short circuits, and ultimately lowering safety hazards. This design also has wider applicability. This utility model has a reasonable structural design. Through the cooperation between the No. 2 handwheel, rotating shaft, synchronous pulley, synchronous belt, worm section, worm wheel, threaded rod, threaded cylinder, moving plate and fixed plate, the main body of the power cord will not loosen. This prevents the shaking generated during the car's operation from damaging the insulation layer of the main body of the power cord, reducing the risk of short circuits and thus reducing safety hazards. It is also more widely applicable. Attached Figure Description

[0016] In this embodiment, a fixed disk 19 is fixedly installed on the outer side of the rotating shaft 3. Multiple insertion holes 20 are opened on the outer side of the fixed disk 19. A fixed block 24 is fixedly installed on the front side of the collection box 1. An insertion rod 21 is slidably connected inside the fixed block 24. A fixed ring 22 is fixedly installed on the outer side of the insertion rod 21. A return spring 23 is fixedly connected to the top of the fixed ring 22. The top of the return spring 23 is fixedly connected to the bottom of the fixed block 24. The bottom end of the insertion rod 21 is movably inserted into the corresponding insertion hole 20. The fixed disk 19 is fixed by the insertion rod 21.

[0017] In this embodiment, a first handwheel 4 is fixedly installed on the front side of the rotating shaft 3, and a second handwheel 7 is fixedly connected to one end of one of the rotating shafts 8. Synchronous pulleys 15 are fixedly installed on the outer sides of both rotating shafts 8, and the same synchronous belt 16 is sleeved between the two synchronous pulleys 15 to facilitate driving the two rotating shafts 8 to rotate together.

[0018] In this embodiment, four T-shaped sliders 17 are fixedly installed on the outer sides of the two moving plates 13, and eight T-shaped grooves 18 are opened on the inner side of the collection box 1. The outer sides of the eight T-shaped sliders 17 are slidably connected to the corresponding T-shaped grooves 18, making the movement of the moving plates 13 more stable.

[0019] In this embodiment, the ends of the two threaded rods 11 that are far apart from each other are rotatably installed on the inner side of the top wall and the inner side of the bottom wall of the collection box 1, respectively. The upper worm segment 9 is engaged with the rear side of the upper worm wheel 10, and the lower worm segment 9 is engaged with the front side of the lower worm wheel 10. A collection hole is provided on one side of the collection box 1, and an annular wear-resistant pad 6 is fixedly installed in the collection hole. The outer side of the power cord body 5 is slidably connected to the inside of the annular wear-resistant pad 6. The annular wear-resistant pad 6 prevents damage to the outer side of the power cord body 5 during the collection process.

[0020] In this embodiment, during use, firstly, by pulling the insertion rod 21, the insertion rod 21 is disengaged from the insertion hole 20, thus removing the insertion rod 21 from fixing the fixed plate 19. Then, the first handwheel 4 is rotated to drive the rotating shaft 3 to rotate, further driving the collecting roller 2 to rotate, thereby collecting the power cord body 5. After the power cord body 5 has been collected, the insertion rod 21 is released, allowing it to re-insert into the insertion hole 20 under the action of the return spring 23, thus re-fixing the fixed plate 19 and preventing the collecting roller 2 from continuing to rotate. Then, by rotating the second handwheel 7, the rotating shaft 8 is driven to rotate, further driving the synchronous wheel 15 to rotate. Simultaneously, as the synchronous wheel 15 rotates, it synchronizes with the rotating shaft 8. The belt 16 causes the two rotating shafts 8 to rotate simultaneously. Furthermore, the two rotating shafts 8 drive the two worm gear segments 9 to rotate, and the two worm gear segments 9 respectively drive the meshing worm wheels 10 to rotate. The two worm wheels 10 then drive the two threaded rods 11 to rotate, which in turn drive the threaded cylinders 12 connected to them to move. The two threaded cylinders 12 further drive the two moving plates 13 to rotate, causing the two fixed plates 14 to move closer together and fix the power cord body 5 wound around the outside of the collecting roller 2. This prevents the power cord body 5 from loosening, thus preventing damage to the insulation layer of the power cord body 5 caused by shaking during vehicle operation, reducing the risk of short circuits, and thus reducing safety hazards and broadening its practicality.
