Description

Technical Field

[0001] The present invention relates to the technical field of inverters, and in particular to a portable inverter. Background Art

[0002] An inverter is a converter that converts DC power (battery, storage battery) into constant frequency and voltage or frequency and voltage adjustable AC power (usually 220V, 50Hz sine wave).

[0003] The application number in the existing public technology is: CN202221864253.X. A portable inverter solves the problem in the prior art that the winding structure easily causes the connection part between the wire and the inverter to fall off and easily causes damage to the wire.

[0004] However, the above patent still has certain disadvantages when in use: although the cable can be retracted and released by a reel, manual operation is required during the retraction process, which increases the labor intensity of the personnel and is time-consuming and laborious to handle. At the same time, there is a lack of cleaning measures for the cables when they are retracted, which can easily bring external dust into the inverter, thereby causing damage to the internal circuit board and affecting the normal use of the device. At the same time, the USB interface and socket on the surface of the portable inverter are usually directly exposed to the outside, which can easily cause dust to enter during daily use and idle placement, affecting subsequent use, and the overall use effect is not very good.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0006] 1. Technical issues to be resolved

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a portable inverter with the following beneficial effects:

[0020] (1) The present invention adopts a torsion spring, a cleaning ring, and a water absorption ring. When the external wiring is pulled, the carrier plate is driven to rotate, causing the torsion spring at the bottom to deform and accumulate energy. After subsequent use, the pull plate is pulled out, and the torsion spring is reset to release energy to drive the winding shaft to rotate, thereby realizing the gathering and winding operation of the external wiring, which is convenient for subsequent use.

A protective cover 5 is rotatably connected between the connecting sockets 6, and a groove is provided on the surface of the protective cover 5. The USB sockets 2 and the ordinary sockets 3 are the basic structures on the portable inverter, so they will not be elaborated on.

[0033] In one embodiment, a magnetic sheet 4 is provided on the inner surface of the protective cover 5 and at the corresponding position on the surface of the portable inverter body 1.

[0039] Working principle: In actual use, when the portable inverter body 1 needs to be used, the pull plate 17 can be pulled to disengage the plug rod 16 from the opening on the surface of the fixing seat 21 and the carrier plate 19, and then the personnel can pull the external wire 12 to change the length of the external wire 12 to facilitate its connection with the power supply equipment. Moreover, when the external wire 12 is pulled, since it is previously wound on the winding shaft 22, the winding shaft 22 will be rotated when it is pulled, so that the carrier plate 19 can rotate it. The torsion spring 20 connected to the bottom rotates, causing the torsion spring 20 to deform and accumulate energy. When the external wire 12 is adjusted, the pull plate 17 is released. At this time, the insertion rod 16 can be driven by the reset spring 18 to reinsert the insertion rod 16 into the opening, thereby fixing the winding shaft 22. After the external wire 12 is used, the insertion rod 16 is removed again, and the deformation of the torsion spring 20 is reset to release energy, so that the winding shaft 22 can be driven to rotate, thereby winding and reeling the external wire 12 to achieve the purpose of automatic retraction. The external wire 12 is also gathered in the storage box 11, and the storage box 11 is located on the surface of one side of the portable inverter body 1 and is not connected to the internal structure. Therefore, it can further avoid damage to the circuit board during the storage process, thereby ensuring the safety of the structure. At the same time, when it is necessary to connect multiple plugs, the USB port 2 or the ordinary port 3 can be exposed by opening the protective cover 5 at the corresponding position, thereby facilitating the connection and use of the line. After use, the space around the port can be sealed by the adsorption of the magnetic strip and the sealing of the protective cover 5, thereby preventing the intrusion of external dust and causing pollution of the port, thereby ensuring the subsequent use effect. The device as a whole has the advantages of structural dustproof, labor-saving cable storage and release, and less damage to cable cleaning.
