[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0029] like Figure 1 and Figure 2 As shown, the present invention proposes a power cord that can eliminate tangling, comprising an insulating sleeve 1 and a conductor 2. The insulating sleeve 1 is sleeved on the outside of the conductor 2, and the insulating sleeve 1 protects the conductor 2 and also prevents leakage. The output end of the conductor 2 is connected to a pin 3, which can receive power and transmit it to the required power equipment through the conductor 2.

[0030] As one implementation method, such as Figure 2 , Figure 3 and Figure 4As shown, this embodiment also includes multiple sets of limiting square tubes 4 disposed on the outside of the insulating sleeve 1. When the insulating sleeve 1 is passed through the multiple sets of limiting square tubes 4, the insulating sleeve 1 will be geometrically interfered with by the multiple sets of limiting square tubes 4 when it is twisted, which physically limits excessive rotation and thus avoids the insulating sleeve 1 from becoming entangled. Each set of limiting square tubes 4 has a fixing block 5 and an L-block 6 fixedly attached to its outer side. The fixing block 5 and the L-block 6 are hinged to each other. When it is necessary to store the insulating sleeve 1, the fixing blocks 5 and the L-block 6 on the multiple sets of limiting square tubes 4 can cooperate with each other, such as... Figure 3 As shown, the left limiting square tube 4 can rotate along the L block 6 of the right limiting square tube 4 through the fixing block 5, thereby bending the insulating sleeve 1, reducing the floor space occupied by the insulating sleeve 1, and achieving the function of winding.

[0031] Furthermore, such as Figure 3 and Figure 4 As shown, the limiting component in this embodiment is set inside the limiting square tube 4 to limit the square tube 4 to adapt to insulating sleeves 1 of different sizes. When facing insulating sleeves 1 of different sizes, the limiting component can move according to the size of the insulating sleeve 1 to ensure continuous compression of the insulating sleeve 1 and achieve the function of fixing.

[0032] Furthermore, such as Figure 3 and Figure 4 As shown, the limiting assembly includes a pair of arc-shaped plates 7 and a pair of springs 8. The limiting assembly is described in detail below:

[0033] A pair of arc-shaped plates 7 are symmetrically distributed on both sides of the insulating sleeve 1, and the arc-shaped plates 7 are in contact with the insulating sleeve 1. A pair of springs 8 are respectively fixed to the ends of the pair of arc-shaped plates 7 away from the insulating sleeve 1, and the ends of the pair of springs 8 away from the insulating sleeve 1 are fixed to the inner wall of the limiting square tube 4. In the initial state, the elastic potential energy of the springs 8 will drive the arc-shaped plates 7 to approach the insulating sleeve 1, which will limit the insulating sleeve 1. When facing a larger insulating sleeve 1, the springs 8 can be compressed to provide space for the insulating sleeve 1. It should be noted that when the insulating sleeve 1 is bent and rolled up, it can overcome the elastic potential energy of the springs 8 and the friction between the arc-shaped plates 7 and the insulating sleeve 1.

[0034] In addition, such as Figure 4 As shown, a groove 9 is provided on the inner wall of the limiting square tube 4. A slider 10 is slidably connected inside the groove 9. The groove 9 can limit the slider 10 and restrict its movement direction. The end of the slider 10 away from the limiting square tube 4 is fixedly connected to the end of the arc plate 7 away from the insulating sleeve 1, ensuring that the arc plate 7 can only move up and down along the inner wall of the limiting square tube 4 when it moves, thus improving the stability during movement.

[0035] As one implementation method, such as Figure 5As shown, the insulating sleeve 1 has a storage compartment 11 at one end near the pin 3, and the pin 3 is fixedly connected to the storage compartment 11. The storage compartment 11 is made of insulating material and does not transmit electricity. A horizontal plate 12 is slidably connected inside the storage compartment 11. A buffer component is provided inside the storage compartment 11. When the pin 3 is inserted or removed, an impact force will be generated instantly, and the buffer component will reduce the impact force caused by inserting or removing the pin 3, thereby reducing the damage caused by the impact force.

[0036] Furthermore, such as Figure 5 As shown, the buffer assembly includes a limiting rod 13 and a spring 15. The buffer assembly is described in detail below:

[0037] The limiting rod 13 is fixed to the inner wall of the storage compartment 11 and passes through the horizontal plate 12. When the pin 3 is inserted, the pin 3 will be subject to some resistance, which will cause the pin 3 to move towards the insulating sleeve 1. At this time, the pin 3 will simultaneously drive the storage compartment 11 to move, and the storage compartment 11 will then drive the limiting rod 13 to move along the inside of the horizontal plate 12. The second spring 15 is sleeved on the outside of the limiting rod 13, and the two ends of the second spring 15 are fixed to the storage compartment 11 and the horizontal plate 12 respectively. When the limiting rod 13 moves, it will cooperate with the horizontal plate 12 to squeeze the second spring 15, causing the second spring 15 to deform and generate elastic potential energy. The deformation of the second spring 15 can partially buffer the pin 3 through the storage compartment 11.

[0038] Furthermore, such as Figure 5 As shown, the buffer assembly is provided in two sets, which are symmetrically distributed at both ends of the horizontal plate 12. The two sets of buffer assemblies can be used in place of the other set if one set is damaged.

[0039] Among them, such as Figure 5 As shown, a baffle 16 is fixedly connected to the end of the limiting rod 13 away from the spring 15. The diameter of the baffle 16 is larger than the diameter of the limiting rod 13. The baffle 16 can limit the horizontal plate 12 and prevent the horizontal plate 12 from disengaging from the outside of the limiting rod 13.

[0040] In addition, such as Figure 3 and Figure 4 As shown, a pair of buffer plates 17 are fixed to both ends of the limiting square tube 4. The buffer plates 17 are made of rubber. The buffer plates 17 can shield the spring 8 and prevent accidental contact. At the same time, the rubber material can reduce the impact force when the hand collides.

[0041] In this embodiment, the insulating sleeve 1 is passed through multiple sets of limiting square tubes 4. When the insulating sleeve 1 is twisted, it will be geometrically interfered by the multiple sets of limiting square tubes 4, which physically limits excessive rotation, thereby avoiding the situation of the insulating sleeve 1 getting tangled. When the insulating sleeve 1 needs to be stored, the fixing block 5 and L block 6 on the multiple sets of limiting square tubes 4 can cooperate with each other. The left limiting square tube 4 can rotate along the L block 6 of the right limiting square tube 4 through the fixing block 5, thereby bending the insulating sleeve 1, reducing the floor area of ​​the insulating sleeve 1, and achieving the function of winding. In the initial state, the elastic potential energy of the spring-8 will drive the arc plate 7 to approach the insulating sleeve 1, which will limit the insulating sleeve 1. When facing a larger size insulating sleeve 1, the spring-8 can be compressed to provide space for the insulating sleeve 1.

[0042] When the pin 3 is inserted, the pin 3 will be subject to some resistance, and the resistance will cause the pin 3 to move towards the insulating sleeve 1. At this time, the pin 3 will simultaneously drive the storage compartment 11 to move, and the storage compartment 11 will then drive the limiting rod 13 to move along the inside of the horizontal plate 12. When the limiting rod 13 moves, it will cooperate with the horizontal plate 12 to compress the second spring 15, causing the second spring 15 to deform and generate elastic potential energy. The deformation of the second spring 15 can partially buffer the pin 3 through the storage compartment 11.

[0043] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
