Description

Technical Field

[0001] The present application relates to the technical field of power cords, and in particular to a power cord assembly having a structure for preventing excessive bending angles. Background Art

[0002] Power cords are wires that transmit current. Usually, the current is transmitted point-to-point. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires that transmit higher voltage alternating current. Due to the higher voltage, these wires need to obtain safety certification according to unified standards before they can be officially produced. DC cords basically transmit lower voltage direct current, so the safety requirements are not as strict as AC cords. However, for safety reasons, countries still require unified safety certification.

[0003] However, the power cord is prone to bend when not in use or when stored. If the bending angle is too large, the surface of the power cord may be worn or broken. Therefore, a power cord assembly with a structure that prevents excessive bending angles is needed to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a power cord assembly with a structure to prevent the power cord from being bent at excessive angles, so as to solve the technical problem in the prior art that the power cord is easily bent when not in use or when stored, and if the bending angle is too large, it will cause the surface of the power cord to wear or break.

[0005] The above-mentioned purpose of the present application is achieved through the following technical scheme: a power cord assembly with a structure to prevent excessive bending angles, comprising a power cord and a storage device for storing the wires, the power cord comprising a wire layer, a spring layer and an outer sheath, the wire layer is wrapped with wires, the spring layer is composed of a long spring, the long spring is sleeved on the wire layer, and the outer sheath wraps the spring layer.

[0006] By adopting the above technical solution, the spring is sleeved on the wire layer, so that when the wire is bent, the bending angle will be limited due to the setting of the spring, so that the bending angle of the power cord will not be too large, thereby solving the technical problem that the power cord is easily bent when not in use or when the power cord is stored, and the bending angle is too large, which will cause the surface of the power cord to wear or break.

[0007] Furthermore, the storage device includes a supporting platform, two opposite fixed plates, a rotating shaft and a reel, the two fixed plates are fixedly connected to the supporting platform with a gap between them, the rotating shaft is located between the two fixed plates and is rotatably connected to the fixed plates, and the reel is fixedly connected to the rotating shaft.

[0008] By adopting the above technical solution, the power cord is wound around the reel once, and then the reel is rotated to roll up the remaining power cord.

[0009] Furthermore, a thread groove is provided on the reel, and the thread groove is a thread-shaped groove.

[0010] By adopting the above technical solution, when winding the power cord, the power cord is first wound around the thread groove, and then the reel is rotated to wind the remaining power cord into the thread groove, so that the power cord will not be stacked and tangled on the reel.

[0011] Furthermore, a fixing device for fixing the power cord is provided in the threaded groove.

[0012] By adopting the above technical solution, when the power cord is turned around the reel, one hand is required to press one end of the power cord, and then the other end of the power cord is held and turned around the reel. This operation is very troublesome. The setting of the fixing device solves this technical problem. Only one end of the power cord can be fixed with the fixing device.

[0013] Furthermore, the fixing device includes a main body, a threaded rod and a pressure plate. The main body is arranged in a threaded groove and fixedly connected to the reel. Through holes are opened on both sides of the main body. The threaded rod is arranged at the upper end of the main body and is threadedly connected to the main body. The threaded rod extends into the main body, and the pressure plate is fixedly connected to one end of the threaded rod extending into the main body.

[0014] By adopting the above technical solution, the power cord is passed through the main body through the opening, and then the threaded rod is screwed into the main body, so that the pressure plate fixedly connected to the threaded rod presses the power cord, thereby achieving the purpose of fixing one end of the power cord on the reel.

[0015] Furthermore, the outer sheath is made of PVC.

[0016] By adopting the above technical solution, the outer sheath made of PVC has low cost, good flexibility, is quite strong, and has the effects of fire resistance and oil resistance.

[0017] Furthermore, a handle is provided at one end of the fixing plate away from the supporting platform.

[0018] By adopting the above technical solution, the handle makes it convenient to carry the storage device.

[0019] Furthermore, both of the two fixing plates are provided with handles, and the handles are located in the middle of the fixing plates.

[0020] By adopting the above technical solution, handles are provided on both fixing plates, which can make the storage device more stable when being carried. The handles are located in the middle of the fixing plates so that the storage device will not tilt or shake when being carried.

[0022] 1. By configuring the power cord to include a wire layer, a spring layer and an outer sheath, the spring is sheathed on the wire layer, so that when the wire is bent, the bending angle is limited due to the setting of the spring, so that the bending angle of the power cord will not be too large, thereby solving the technical problem that the power cord is easily bent when not in use or when the power cord is stored, and the surface of the power cord will be worn or broken when the bending angle is too large.

[0023] 2. Through the arrangement of the storage device and the fixing device, when the power cord needs to be rolled up, one end of the power cord is passed through the main body through the through opening, and then the threaded rod is twisted to make the pressure plate press the power cord, and then the reel is rotated to store the power cord, so that the purpose of easily rolling up the power cord is achieved.

DETAILED DESCRIPTION

[0028] The present application is further described in detail below with reference to the accompanying drawings.

[0029] Example, see Figure 1 , Figure 2A power cord assembly with a structure for preventing excessive bending angles comprises a power cord 1 and a storage device 2 for storing electric wires. The power cord 1 comprises a wire layer 10, a spring layer 11 and an outer sheath 12. The wire layer 10 is wrapped with electric wires. The spring layer 11 is composed of a long spring. The long spring is sleeved on the wire layer 10. The outer sheath 12 wraps the spring layer 11. The storage device 2 comprises a support platform 20, two opposite fixed plates 21, a rotating shaft 22 and a reel 23. The two fixed plates 21 are fixedly connected to the support platform 20 with a gap between them. The rotating shaft 22 is located between the two fixed plates 21 and is rotatably connected to the fixed plates 21. The reel 23 is fixedly connected to the rotating shaft 22. The spring is sleeved on the wire layer 10, so that when the wire is bent, the bending angle will be limited due to the setting of the spring, so that the bending angle of the power cord 1 will not be too large, which solves the technical problem that the power cord 1 is easily bent when not in use or when the power cord 1 is stored, and the surface of the power cord 1 will be worn or broken when the bending angle is too large. Because the spring is added to the structure of the power cord 1, the storage of the spring can only be implemented by winding up. Therefore, a storage device 2 is provided. It is used like this: one hand presses one end of the power cord 1, and then holds the other end of the power cord 1 and turns it around the reel 23, and then rotates the reel 23 to wind up the remaining power cord 1.

[0030] Simply winding the power cord 1 onto the reel 23 will cause the power cord 1 to be stacked messily on the reel 23, and the stacked power cords 1 may get tangled and stuck together. In order to solve this technical problem, in this embodiment, a threaded groove 24 is provided on the reel 23, and the threaded groove 24 is a thread-shaped groove. When winding the power cord 1, the power cord 1 is first wound around the threaded groove 24, and then the reel 23 is rotated to wind the remaining power cord 1 into the threaded groove 24, which prevents the power cord 1 from being stacked and tangled on the reel 23.

[0031] One hand presses one end of the power cord 1, and then holds the other end of the power cord 1 and turns it around the reel 23. This operation is very troublesome. In order to more conveniently reel in the power cord 1, refer to Figure 3In this embodiment, a fixing device 3 is provided in the threaded groove 24, and the fixing device 3 includes a main body 30, a threaded rod 31 and a pressure plate 32. The main body 30 is arranged in the threaded groove 24 and fixedly connected to the reel 23. Through holes 33 are provided on the front and rear sides of the main body 30. The threaded rod 31 is arranged at the upper end of the main body 30 and is threadedly connected to the main body 30. The threaded rod 31 extends into the main body 30, and the pressure plate 32 is fixedly connected to one end of the threaded rod 31 extending into the main body 30. The power cord 1 passes through the main body 30 through the through hole 33, and then the threaded rod 31 is screwed into the main body 30, so that the pressure plate 32 fixedly connected to the threaded rod 31 presses the power cord 1, thereby achieving the purpose of fixing one end of the power cord 1 on the reel 23. After fixing one end of the power cord 1, the reel 23 can be rotated to retract the power cord 1.

[0032] In order to facilitate the transportation of the storage device 2, in this embodiment, a handle 25 is provided in the middle part of the two fixed plates 21 away from the end of the support platform 20. When the storage device 2 needs to be transported, the handle 25 can be held for transportation. Both fixed plates 21 are provided with handles 25, which can make the storage device 2 more stable when being transported. The handle 25 is located in the middle part of the fixed plate 21, so that the storage device 2 will not tilt or shake when being transported.

[0033] Specific implementation process: when the power cord 1 needs to be rolled up, one end of the power cord 1 is passed through the main body 30 through the opening 33, and then the threaded rod 31 is twisted to make the pressure plate 32 press the power cord 1, and then the reel 23 is rotated to retract the power cord 1.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
