Problems solved by technology

[0004] Many safety door devices mostly use the plug extrusion type to open the safety door, such as a socket protection door structure assembly disclosed in Chinese patent CN204577691U and a socket protection door structure assembly disclosed in Chinese patent CN204947166U. The false touch safety protection function cannot avoid electric shock accidents caused by false touches with fingers or metal objects. Therefore, there is an urgent need for a safety door device that can be inserted into a single hole and self-locked.

Abstract

The present invention relates to a lever type single-hole self-locking safety door device. The lever type single-hole self-locking safety door device is used for a five-hole socket and comprises a shell composed of an upper casing (1) and a lower bottom plate (2) and a safety door arranged outside the shell, the two-pin jacks (3) and the three-pin jacks (4) are both arranged at the corresponding positions of the upper casing (1) and the lower bottom plate (2), and the safety door comprises a two-pin protective door (5) and a three-pin protective door (6) which are arranged relatively and an elastic member (7) connected between the two-pin protective door (5) and the three-pin protective door (6). Each of the two-pin protective door (5) and the three-pin protective door (6) is composed of a rotating shaft (8) and two wing plates (9) connected with the rotating shaft (8), the two-pin protective door (5) and the three-pin protective door (6) both can slide along the axial directions of the rotating shafts (8) and rotate around the axial directions of the rotating shafts (8), and the guiding and locking assemblies matching the wing plates (9) are arranged inside the shell. Compared with the prior art, the lever type single-hole self-locking safety door device of the present invention has the advantages of being self-locking and sensitive, being smooth to open, being compact in structure, etc.

Description

technical field [0001] The invention belongs to the technical field of power sockets, and relates to a safety door device, in particular to a lever-type single-hole self-locking safety door device. Background technique [0002] Electricity provides convenient and stable energy for modern families. However, since "electricity" is invisible to the naked eye, accidents such as electric shock or leakage may occur due to negligence, resulting in damage to life and property. Especially in families with young children or young children, special attention should be paid to the safety of using electricity. [0003] The General Administration of Quality Supervision, Inspection and Quarantine and the National Standards Committee approved and released 35 national standards on October 13, 2015, including "Plugs and Sockets for Household and Similar Purposes Part 2-5: Special Requirements for Converters", and the standard numbers are GB 2099.3- 2015 and GB2099.7-2015, which will be imple...
