[0002] The charger is a charging device that uses high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology. The charger (charger) can be divided into industrial frequency machine and high frequency machine according to the design circuit working frequency. The industrial frequency machine is designed based on the traditional analog circuit principle. The internal power components of the machine (such as transformers, inductors, capacitors, etc.) are relatively large. Generally, there is a small noise when running with a large load, but this model has strong resistance performance in harsh power grid environment conditions, and its reliability and stability are stronger than high-frequency machines.

[0003] At present, the power plug part of the existing charger is an independent three-phase or two-phase setting. When the power socket is two-phase, three-phase, square column, cylindrical or other special shapes, it is impossible to timely power and charge computers, mobile phones, speakers and other electrical appliances through the power plug part, which is inconvenient for users and does not meet the actual use needs. Therefore, a charger self-locking structure is urgently needed to solve the above problems. Utility Model Content

[0013] As a further solution of the utility model: a circular hole is opened on the outer wall of one side of the connecting plate, and one end of the metal rod passes through the inside of the circular hole.

[0014] As a further solution of the utility model: a guide rod is fixedly connected to an inner wall of one side of the self-locking groove, a guide groove is opened on one side of the plug, and the guide rod cooperates with the guide groove.

[0015] As a further solution of the utility model: a first groove is formed on the top of the charging seat, and a second groove is formed on the bottom of the first groove.

[0016] As a further solution of the utility model: a connecting column is fixedly connected to the top outer wall of the first circular plate, one end of the connecting column extends from the inside of the cylindrical groove to the inside of the second groove, and the end of the connecting column away from the first circular plate is fixedly connected to a fixing ring.

[0018] After adopting the above structure, the utility model has the following advantages compared with the prior art: it is capable of replacing different types of plugs, and the replaced plugs can be tightly fixed to the charging seat through the self-locking assembly. Specifically, by providing a charging seat, a plug and a self-locking assembly, when the staff needs to lock the plug, they can first insert the plug into the self-locking groove. At this time, the guide groove opened at the bottom of the plug cooperates with the guide rod to move into the self-locking groove until the end of the plug presses the connecting plate. At this time, the first spring on one side of the connecting plate will be compressed, and the compression of the first spring will cause the connecting plate to shrink together. In the process of the connecting plate shrinking, the baffle will separate from the card column. When the limiting effect of the baffle on the card column is released, the second spring in a compressed state will immediately recover its deformation and bounce it into the positioning hole, thereby realizing automatic locking of the plug and ensuring that people can still use it stably after replacing different types of plugs.

The plug 6 can be first inserted into the self-locking groove 23. At this time, the guide groove 8 provided at the bottom of the plug 6 cooperates with the guide rod 24 to move into the self-locking groove 23 until the end of the plug 6 presses the connecting plate 12. At this time, the first spring 14 on one side of the connecting plate 12 will be compressed, and the compression of the first spring 14 will cause the connecting plate 12 to retract together. During the retraction of the connecting plate 12, the baffle 16 will be separated from the post 20. When the limiting effect of the baffle 16 on the post 20 is released, the second spring 28 in a compressed state will immediately restore its deformation and bounce it into the positioning hole 7, thereby realizing automatic locking of the plug 6 and ensuring that people can still use it stably after replacing different types of plugs 6.

[0034] Preferably, a circular hole 15 is formed on an outer wall of one side of the connecting plate 12 , and one end of the metal rod 22 passes through the circular hole 15 .

[0035] Preferably, a guide rod 24 is fixedly connected to the inner wall of one side of the self-locking groove 23, and a guide groove 8 is opened on one side of the plug 6. The guide rod 24 cooperates with the guide groove 8 to ensure the stability of the bottom of the plug 6 during self-locking.

[0039] Working principle: When the staff needs to lock the plug 6, the plug 6 can be first inserted into the self-locking groove 23. At this time, the guide groove 8 opened at the bottom of the plug 6 cooperates with the guide rod 24 to move into the self-locking groove 23 until the end of the plug 6 presses the connecting plate 12. At this time, the first spring 14 on one side of the connecting plate 12 will be compressed, and the compression of the first spring 14 will cause the connecting plate 12 to shrink together. During the shrinkage of the connecting plate 12, the baffle 16 will separate from the card column 20. When the limiting effect of the baffle 16 on the card column 20 is released, the second spring 28 in the compressed state will immediately recover its deformation and bounce it into the positioning hole 7, thereby achieving the locking of the plug. 6 is automatically locked, ensuring that people can still use it stably after replacing different types of plugs 6. Later, when the staff needs to replace the plug 6, they can move the cover plate 3 to retract the cover plate 3 into the storage groove 26. At this time, the staff pulls the fixing ring 17 to pull out the card column 20 that is clamped in the positioning hole 7. Then the staff pulls the plug 6 out of the self-locking groove 23 to realize the disassembly of the plug 6. When the plug 6 is disassembled, the first spring 14 in the compressed state will immediately restore its deformation to quickly reset the connecting plate 12. At this time, the baffle 16 continues to block and limit the card column 20, realizing repeated self-locking after the staff replaces different types of plugs 6.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
