The safety door formed by the principle of leverage

Abstract

The invention relates to a safety component of low-voltage connection equipment, in particular to a safety door formed by using the principle of leverage, which is arranged in the upper cover of a socket or a transfer board. The upper cover is provided with at least a pair of jacks, and the lower The outer side of the port is extended downward with a glyph-shaped stopper; the safety door formed by using the principle of leverage includes: bracket, lever, left door panel, right door panel, and torsion spring. It is possible to continue to insert only with great strength, and children do not have such great strength, thus avoiding the danger of electric shock; when the plug is inserted, the safety door will be affected by the principle of labor-saving lever, and the plug can be inserted easily and smoothly, improving the use user satisfaction.

Description

technical field [0001] The invention relates to a safety component of low-voltage connection equipment, in particular to a safety door formed by utilizing the principle of leverage. Background technique [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 occur 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. ...

[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. The 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 the plug is inserted, it resists two inclined surfaces at the same time to make it slide After the block moves horizontally towards one side, the plug is connected to the power supply through the plug. During this process, the downward force of the plug is converted into a horizontal force through two inclined surfaces, and the force transmitted at a 90-degree turn makes the downward force A large amount of consumption, and then it is necessary to increase the downward force to achieve the required thrust to make the slider slide horizontally, so that the plug needs a great force to be inserted; 2. When the slider slides horizontally, the downward force of the plug increases. The friction force when the slider slides increases the sliding resistance of the slider, which in turn makes the slider slide unsmoothly and affects the use effect
