Description

Technical Field

[0001] The utility model relates to the technical field of power cords, in particular to an improved power cord. Background Art

[0002] Power cords are wires that transmit electric current. Current transmission typically occurs point-to-point. Power cords can be categorized by their intended use as AC (alternating current) or DC (direct current). AC cables typically carry higher-voltage alternating current (AC). Due to their higher voltage, these cables require standardized safety certification before they can be officially manufactured. DC cables, on the other hand, carry lower-voltage direct current (DC), so safety requirements are less stringent than those for AC cables. However, for safety reasons, countries still require standardized safety certification.

[0003] For example, a wear-resistant power cord with announcement number CN220041436U and authorization announcement date 2023.11.17 includes a first plug connector, which is arranged at one end of the power cord main body, and a second plug connector is arranged at the other end of the power cord main body; a metal armor sleeve, which is arranged inside the power cord main body, and a flexible triangular limit frame is arranged inside the metal armor sleeve, and a battery cell is arranged outside the flexible triangular limit frame, and polyethylene filler is arranged between the battery cell and the metal armor sleeve; an outer rubber sleeve, which is arranged outside the metal armor sleeve, and a braided wire sleeve is arranged outside the outer rubber sleeve, and the braided wire sleeve is woven by cross-winding multiple metal wires.

[0004] In the above-mentioned and existing technologies, most of the metal plugs are exposed to the outside. The idle metal plugs are subject to external pressure and are prone to deformation or even bending. They are also prone to rusting when exposed to water.

[0026] The utility model provides an improved power cord, including a wire box 1, a wire body 2 and a wire drum 11, with a plug 3 and a connector 4 respectively provided at both ends of the wire body 2, a metal plug 5 is provided on the outer wall of one side of the plug 3, and a protective cover 6 is slidably sleeved on the inside of the plug 3, a guide seat 7 is provided on the outer wall of the plug 3, and a guide block 8 is provided on the inner wall of the protective cover 6, the guide block 8 is slidably connected to the inside of the guide seat 7, a guide rod 9 is provided on the inner wall of the guide seat 7, and the guide block 8 is slidably sleeved on the inside of the guide rod 9, a return spring 10 connected to the guide block 8 is provided on the inner wall of the guide seat 7, and the return spring 10 is sleeved on the outside of the guide rod 9. When the power cord is used up and the plug 3 is unplugged from the external socket, the elastic force of the return spring 10 will push the guide block 8 and the protective cover 6 to move, so that the protective cover 6 covers the outside of the metal plug 5, preventing the metal plug 5 from being deformed or broken by external pressure, and can protect the metal plug 5.

[0027] Beneficial effect: When the plug 3 is idle, the elastic force of the return spring 10 will push the guide block 8 and the protective cover 6 to move, so that the protective cover 6 covers the outside of the metal insert 5, which can protect the metal insert 5 and prevent the metal insert 5 from being deformed or even broken by external pressure.

[0028] In one embodiment provided by the present invention, Figure 2 、 3 and Figure 4 As shown, the wire body 2 passes through the interior of the wire drum 11, and the center point of the wire body 2 is fixed on the inner wall of the wire drum 11. A rotating rod 12 is provided on the outer walls on both sides of the wire drum 11, and the rotating rod 12 is rotatably connected to the inner wall of the wire box 1 through a bearing. The center point of the wire body 2 is fixed on the inner wall of the wire drum 11, and the center point of the wire body 2 will not move.

[0029] In another embodiment provided by the present invention, Figure 4 and Figure 5 As shown, torsion springs 13 connected to the wire drum 11 are provided on the inner walls on both sides of the wire take-up box 1, and the torsion springs 13 are sleeved on the outside of the rotating rod 12. The torsional force of the torsion springs 13 will drive the wire drum 11 to rotate and automatically reel in the wire body 2.

[0030] In another embodiment provided by the present invention, Figure 1 、 4 and Figure 5 As shown, a fixed cylinder 14 is provided on the outer wall of one side of the wire take-up box 1, and an arc-shaped plug-in block 15 is slidably connected to the inside of the fixed cylinder 14. Slots 16 distributed in an annular structure with equal distances are opened on the outer wall of one side of the wire cylinder 11, and the arc-shaped plug-in block 15 is inserted into the inside of the slot 16 to fix the fixed cylinder 14.

[0031] In one embodiment provided by the present invention, Figure 1 、 4 and Figure 5 As shown, a pull rod 17 located outside the fixed tube 14 is provided on the outer wall of one side of the arc-shaped plug 15, and a plug spring 18 connected to the arc-shaped plug 15 is provided on the inner wall of one end of the fixed tube 14. The plug spring 18 is sleeved on the outside of the pull rod 17, and the pull rod 17 can pull the arc-shaped plug 15 out of the inside of the slot 16.

[0032] In another embodiment provided by the present invention, Figure 6 As shown, the wire body 2 includes a heat-resistant layer 19 and a conductor 20. An insulating layer 21 is provided on the outer wall of the conductor 20, and an anti-oxidation filling layer 22 is filled between the heat-resistant layer 19 and the insulating layer 21. The heat-resistant layer 19 can improve the heat resistance of the power cord.

[0033] In another embodiment provided by the present invention, Figure 6 As shown, a waterproof layer 23 is provided on the outer wall of the heat-resistant layer 19, and a wear-resistant layer 24 is provided on the outer wall of the waterproof layer 23. The waterproof layer 23 and the wear-resistant layer 24 can make the power cord waterproof and wear-resistant.

[0034] Working principle: When in use, pull the plug 3 and the connector 4 in opposite directions respectively, and the wire spool 11 will rotate to unwind the wire body 2. Because one side of the arc-shaped plug block 15 and the slot 16 are both arc-shaped sides, the positive rotation of the wire spool 11 will not be affected unless the arc-shaped plug block 15 is pulled out from the inside of the slot 16 through the pull rod 17. As the wire spool 11 rotates, the torsion spring 13 will accumulate force. After the length of the wire body 2 outside the wire box 1 is pulled to the required length, the plug 3 and the connector 4 are released. Because the bottom sides of the arc-shaped plug block 15 and the slot 16 are straight sides, the wire spool 11 will not rotate after releasing the plug 3 and the connector 4. The arc-shaped plug block 15 limits the wire spool 11 and prevents the wire spool 11 from rotating on its own. For winding, a heat-resistant layer 19, a waterproof layer 23 and a wear-resistant layer 24 are provided on the outside of the wire body 2, which can improve the heat resistance, waterproofness and wear resistance of the power cord and make the power cord more durable. When the power cord is used up and the plug 3 is unplugged from the external socket, the elastic force of the return spring 10 will push the guide block 8 and the protective cover 6 to move, so that the protective cover 6 covers the outside of the metal plug 5, which can protect the metal plug 5 and prevent the metal plug 5 from being deformed or even broken by external pressure. Pulling the pull rod 17 drives the arc-shaped plug block 15 to move out of the inside of the slot 16, and the torsional force of the torsion spring 13 will drive the wire reel 11 to rotate and rewind the wire body 2, thereby realizing the automatic winding function and facilitating the storage of the wire body 2.

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
