flip safety door

Abstract

The invention relates to a safety component of low voltage connecting equipment, in particular to a safety component which is applied to various types of sockets and power supply patch boards and usedfor preventing accidental electric shock. An overturn type safety door comprises a center shaft, a left door panel, a right door panel, a support shaft and a torsional spring, and the left door paneland the right door panel sheathe the center shaft in a bilateral symmetry manner by virtue of a tubular supporting arm I and a tubular supporting arm II. The overturn type safety door provided by theinvention avoids occurrence of an electric shock hazard and is simple in structure and easy to produce and assemble, so that production cost of the safety component product is reduced; meanwhile, a plug can be smoothly inserted without using too much force, thus using effect is improved.

Description

Technical field [0001] The present invention relates to a safety component of low-voltage connection equipment, in particular to a safety component used in various types of sockets and power transfer boards to prevent accidental electric shock. Background technique [0002] Existing wall sockets and portable power adapter boards can be seen everywhere in daily life, but there are also common safety hazards. For example, when children are curious to hold conductive foreign objects into the socket or a certain jack of the power adapter board, It will touch the power contacts inside, leading to the risk of electric shock. Such safety accidents happen from time to time, which greatly affects the safety of the wall socket and the mobile power switch board. [0003] In the invention patent with application number 201010297882.4, a supporting sliding safety door is provided. This technical solution is provided with a sliding block in the upper cover, and the outer side of the sliding bloc...

Problems solved by technology

[0002] Existing wall sockets and mobile power adapter boards can be seen everywhere in daily life, but there are also common safety hazards. For example, when children insert a conductive foreign object out of curiosity into a socket or a jack of the power adapter board It will touch the power contacts inside, resulting in the risk of electric shock. Such safety accidents happen from time to time, which greatly affects the safety of wall sockets and mobile power adapter boards.

[0003] In the invention patent of application number 201010297882.4, a support sliding safety door is provided. In this technical solution, a slider is provided in the upper cover, and the outer side of the slider corresponds to two sockets, and there are two slopes inclined towards one direction. , There is a protruding support shaft inside the slider. When a metal foreign object is inserted into a certain socket, the slider will rotate around the support shaft. block cannot be moved, thereby preventing metal foreign objects from passing through; this technical solution basically solves the problem that existing sockets and transfer boards are prone to electric shock hazards, but there are still the following deficiencies: 1. When a metal foreign object is inserted into a certain jack, the slider moves toward the It cannot be moved until it is rotated for a certain distance, and at this time, the metal foreign matter will be easily inserted into the upper cover along the gap between the inclined surface and the upper cover; After the side moves horizontally, the plug is connected to the power supply. During this process, the downward force of the plug is converted into a horizontal force through the two slopes. The 90-degree turning force is transmitted, so that the downward force is consumed in large quantities. Furthermore, it is necessary to increase the downward force to achieve the required thrust to make the slider slide horizontally, resulting in the plug needing a great force to be inserted; 3. When the slider slides horizontally, the downward force of the plug increases the sliding speed of the slider. When the friction force increases, the sliding resistance of the slider increases, and then the sliding of the slider is not smooth, which affects the use effect
