Abstract
The utility model relates to a safety electric plug with a safety device, which is composed of a main body (1) formed into compression molding by a rubber plastic material, a conducting strip (2) connected with a power line (8) at the front end of the main body (1), and a safe cover (3). The inner part of the safe cover (3) is provided with a hollow column (4) whose upper opening and lower opening are sealed. The hollow column (4) is sheathed in the side opening of (6) the main body (1), and a fixing point (5) arranged at the passing through hollow point is connected with the main body (1). The inner end of the hole (6) is provided with a spring (7). Under the actions of the user's external force and the spring (7), the safe cover (3) moves form top to bottom, having the action of synchronously protecting the user's safety.
Description
The utility model is a kind of safety utilization of electric power plug.
Used is by the plane conducting strip of two connection power lines and rubber-plastics material compression molding with plug, all exposes with the conducting strip of plug front portion.People in use, the particularly present porous that various electrical appliance flocked together electrical socket is easy to cause the electric shock phenomenon; Cause unnecessary tragedy.
The utility model purpose is to propose a kind of safety utilization of electric power plug with safety device.With the plug of using of the present utility model, when user's handle was used electrical socket with the plug insertion, safety guard also correspondingly retreated under the effect of external force; And extracting when use electrical socket with plug, safety guard is synchronized with the movement in the other direction from action by the effect of spring force, and this has just played stops to expose conducting strip, is perfectly safe in user's effect.
The utility model is adopt to improve existing structure with plug, and increases safety device and realize goal of the invention.The technical solution of the utility model is at the exposed conducting strip place with the plug front portion, increases a safety guard, and safety guard be connected with the hold-down screw on the plug after the upper and lower slip of energy.Safety guard inserts, extracts with plug when using electrical socket under the effect of spring force, can both play and being synchronized with the movement of user.Rolling has concavo-convex streakline on conducting strip, offset with plug with increase frictional force and insert fully when using electrical socket, the reaction force that is produced behind the spring pressurized, so just in use the way break away from easily.
Owing to increased safety guard on the structure, add the reaction force that upper spring produces and the rolling streakline of conducting strip, make the utility model finish the invention task.
Fig. 1 is the manufacturing structure example of the utility model safety utilization of electric power plug.
The utility model safety utilization of electric power plug is formed (Fig. 1) by three parts.Main body (1) is the rubber-plastics material compression molding, and its front end has the conducting strip (2) of connection power line (8), and leaves hole (6) on both sides.Safety guard (3) is connected by the fixing point (5) on two upper and lower hollow pillar stands that seal (4) and the main body (1), carries out upper and lower moving under the effect of spring (7) power.
In the main body of rubber-plastics material compression molding (1), front end has the conducting strip (2) of connection power line (8).The equal rolling on two planes of conducting strip (2) has concavo-convex streakline, inserts with the frictional force behind the electrical socket to increase with plug, offsets the reaction force that is produced behind spring (7) pressurized.Guarantee to use with during the plug, plug can be owing under spring (7) the power effect, and breaks away from the phenomenon with electrical socket voluntarily.
There are two upper and lower hollow pillar stands that seal (4) inside of safety guard (3).Spring (7) is arranged at the top of being inserted in main body (1) two lateral opening (6) at column (4), has a screw (5) to be fixed in main body (1) by vacancy in the column (4).
When using electrical socket with the plug insertion, spring (7) compresses the back and produces reaction force.Because the reaction force of spring (7) is less than the frictional force of conducting strip (2), the safety guard (3) of this moment remains static.And need extract with plug when using electrical socket, because the effect of external force, the active force of spring (7) promotes column (4) and does reciprocal being synchronized with the movement, safety guard (3) is covering conducting strip (2) all the time.
The safety device of the utility model safety utilization of electric power plug is applicable to the various plugs of using.The balance of cover (3) if need tighten security is then as long as increase lateral opening (6) and corresponding column (4).
Claims (4)
1, a kind of safety utilization of electric power plug, main body (1) by the rubber-plastics material compression molding, having the conducting strip (2) of connection power line (8) and safety guard (3) to link to each other at main body (1) front end forms, it is characterized in that the upper and lower hollow pillar stand that seals (4) being arranged in the inside of safety guard (3), have a screw (5) to be fixed in main body (1) in the middle vacancy of column (4), safety guard (3) can upper and lower motion under the effect of power.
2, by the described safety utilization of electric power plug of claim 1, it is characterized in that lateral opening (6) inner stressed back reaction force that produces of spring (7) of main body (1), promote the opposite direction that safety guard (3) is done when extracting with electrical socket with plug and be synchronized with the movement.
3, by the described safety utilization of electric power plug of claim 1, the equal rolling in two planes that it is characterized in that connecting the conducting strip (2) of power line (8) has concavo-convex streakline.
4, by the described safety utilization of electric power plug of claim 1, it is characterized in that the inner hollow pillar stand (4) of safety guard (3) is inserted in lateral opening (6) on the main body (1), and can upper and lower motion.
