Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a safety socket with a self-locking structure. Background Art

[0002] According to national mandatory standards, existing sockets must be safety sockets, that is, an insulator must be installed above the socket socket. When the user uses the socket, a large force is required to insert the plug. After the plug is pulled out, the insulator automatically resets under the action of the reset spring, blocking the metal electrode below, thereby preventing electric shock.

[0003] According to the existing Chinese utility model patent with the announcement number CN 207800980 U, a socket protection door structure and a socket are disclosed. The socket protection door structure includes a base, a two-pole socket protection door, a three-pole socket protection door, a first elastic member and a second elastic member. The two-pole socket protection door and the three-pole socket protection door are both slidably connected to the base, and the two-pole socket protection door and the three-pole socket protection door can move relatively independently. Since the two-pole socket protection door and the three-pole socket protection door provided by the utility model can slide relatively independently, that is, when the user uses the two-pole socket, the three-pole socket protection door will not be opened, and when the three-pole socket is used, the two-pole socket protection door will not be opened, so that the two-pole socket protection door and the three-pole socket protection door work relatively independently, and the safety factor is relatively high.

[0004] However, at present, this type of structure has a baffle or a protective door. When the end of the plug applies downward pressure to the baffle, the friction between the baffle and the base increases, which may make it difficult for the baffle to move to the side away from the air avoidance hole, resulting in the user needing to use greater force to insert the plug into the socket. At the same time, the user uses greater force to plug in, which can easily damage the plug and socket, thereby causing safety hazards. Therefore, in view of these current situations, it is urgent to develop a safety socket with a self-locking structure to meet the needs of actual use. Utility Model Content
