Description

Technical Field

[0001] The utility model relates to the field of power cords, in particular to a power cord with a protection mechanism. Background Art

[0002] A power cord is a wire for transmitting current. Usually, the way of current transmission is point-to-point transmission. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires for high-voltage alternating current. Since such wires have a high voltage, they need to meet unified standards and obtain safety certifications before they can be officially produced. DC wires are basically for low-voltage direct current. Therefore, the safety requirements are not as strict as those of AC wires. However, for safety reasons, countries still require unified safety certifications.

[0003] In a Chinese patent, a power cord with a protective sleeve is disclosed, and its patent number is CN213692454U. In the power cord with a protective sleeve, it includes a wire, an exposed plug arranged at one end of the wire, a hidden plug arranged at the other end of the wire, and a protective sleeve cooperating with the exposed plug. The protective sleeve is detachably connected to the exposed plug. A connecting component for fixing the protective sleeve is arranged on the wire. The connecting component includes a collar sleeved on the wire and a connecting seat arranged on the collar. A clamping block is arranged on the connecting seat, and the protective sleeve is clamped and cooperated with the clamping block. After the exposed plug of the power cord with a protective sleeve is pulled out from the power socket, the protective sleeve can be taken off from the connecting seat for use. When the protective sleeve is not in use, the protective sleeve can be clamped and fixed to the clamping block on the connecting seat, thus reducing the situation of the protective sleeve being lost, and the operation is also very convenient.

[0004] The above-mentioned disclosed patent has the following disadvantages:

[0006] (2) When using the power cord in the external environment in the prior art, it may be affected by the humid water vapor in the external environment at the connection between the power cord and other devices. The humid water vapor will affect the inside of the power cord, thus affecting its normal use.

[0007] (3) In the prior art, at the connection between the head and the wire of the power cord, due to the bending operation during connection, the connection between the two is often damaged, affecting the normal use of the power cord. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] As shown Figures 1 to 4 in the figure, a power cord with a protection mechanism includes a power cord body 1. One end of the power cord body 1 is provided with a plug 2 connected to a power supply. A protection component 3 is arranged on the surface of the power cord body 1. The protection component 3 is provided with a rubber sleeve 301 and a fixed support plate 302, so that the buffer spring 303 and the damping member 304 on the surface of the support plate 302 cooperate with each other to avoid bending. A connector 4 fixed at the other end of the power cord body 1 is connected to a device. A connection frame 5 is arranged outside the connector 4. A straight groove 501 is formed on the surface of the connection frame 5 and a fixed rod 502 is fixed inside. A sliding member 503 connecting a protective cover 6 can slide on the surface of the fixed rod 502. A side cover 7 is arranged on one side surface of the protective cover 6, so that a rotating member 702 installed at the bottom end of the side cover 7 can rotate on the surface of a fixed shaft 703, facilitating the opening and closing of the side cover 7. And a heat dissipation member 8 is arranged on the upper surface of the protective cover 6. The heat dissipation member 8 is provided with ventilation holes 801 for heat dissipation. And an adsorption sponge 802 connected by a fixing bolt 803 is arranged below the ventilation holes 801 to adsorb the water vapor in the air entering the inside of the protective cover 6.

[0032] The rubber sleeve 301 attached to the surface of the power cord body 1 fixes a plurality of symmetrically connected support plates 302.

[0033] Through the above technical solution, the setting of the rubber sleeve 301 can ensure that the power cord body 1 is not damaged by external forces. And through the setting of the symmetric support plates 302, it is ensured that the power cord body 1 can be protected when it is bent to both sides.

[0034] A spring 504 is arranged on the surface of the fixed rod 502 and fixed between the straight groove 501 and the sliding member 503.

[0035] Through the above technical solution, driven by the elastic force of the spring 504, the sliding member 503 can slide on the surface of the fixed rod 502, and it can drive the protective cover 6 to protect the connector 4.

[0036] A first magnetic plate 601 arranged on the bottom surface of the protective cover 6 attracts a second magnetic plate 701 on the surface of the side cover 7.

[0037] Through the above technical solution, through the mutual attraction between the first magnetic plate 601 and the second magnetic plate 701, it is ensured that the side cover 7 can be fixed by magnetic force, so as to ensure that the connector 4 will not be blocked during use.

[0038] The fixed shaft 703 fixedly connected to the inner bottom end of the protective cover 6 is provided with torsion springs 704 at both ends, so that the torsion springs 704 can connect the protective cover 6 and the rotating member 702.

[0039] Through the above technical solution, by setting the torsion spring 704, the side cover 7 can always be attached to one side of the protective cover 6 through the rotating member 702 to seal the connector 4 when not in use.

[0040] When in use, when the user uses a power cord with a protection mechanism, when connecting the circuit with the power cord body 1, the plug 2 is inserted into the power supply, and the connector 4 on the other side is connected to the device. By pulling the protective cover 6 towards one side of the power cord body 1, under the elastic extrusion of the spring 504, the sliding member 503 can slide on the surface of the fixed rod 502, thereby driving the protective cover 6 to move to one side. During the pushing process, the side cover 7 is opened by the connector 4 pressing against it. The side cover 7 is connected by the torsion spring 704 and rotates around the fixed shaft 703 through the rotating member 702. The second magnetic plate 701 on its surface attracts the first magnetic plate 601 on the bottom surface of the protective cover 6 to fix the side cover 7. And under the extrusion of the spring 504, the protective cover 6 can be attached to the outside of the connection part of the connector 4 to block dust, and heat dissipation is carried out through the heat dissipation member 8. The internal adsorption sponge 802 is used to filter water vapor. At the same time, when the plug 2 and the connector 4 are bent, through the cooperation of the buffer spring 303 and the damping member 304, the support plate 302 can always support both of them to be in a vertical state with the power cord body 1, avoiding bending at the connection part.
