Abstract

The utility model relates to a guideway type two-pole socket protecting door. The technical problem to be solved is to provide a guideway type two-pole socket protecting door that can not only efficiently avoid plugging of a one-pole plug, but also allows smooth plugging of a two-pole plug. The utility model comprises an enclosing door, a pressing piece of a protecting rack, and an elastic member. The utility model is characterized in that it comprises additionally a rectangular protecting rack which is pin jointed with the pressing piece of the protecting rack. The rectangular enclosing door is located in a cavity formed by the pressing piece of the protecting rack and the rectangular protecting rack. The two sides of the enclosing door are provided with a cylindrical projected rafter respectively, and the two edges corresponding to the sockets of the protecting rack are provided with upper lobes. The two sides of the protecting rack are provided with guideways matching with the projected rafters. One foot of the elastic member is fixed at one side of the protecting rack, another foot of the elastic member passes below the lower parts of the projected rafters. The utility model is applicable for sockets with two poles and sockets with two grounded poles.

Description

Guide tracked the two poles of the earth socket protective door

Technical field

The utility model relates to a kind of guide tracked the two poles of the earth socket protective door, is applicable to the two poles of the earth of countries and regions such as China, the U.S., Japan, Australia, New Zealand, Saudi Arabia, Canada and the socket of the two poles of the earth band ground connection.

Background technology

At present, socket major part on the market is not to be with shutter, though this socket is simple in structure, price is relatively cheap, but the electric shock phenomenon takes place easily, lives and properties to people produce harm, so people have invented socket protective door miscellaneous and have prevented to get an electric shock, for example the patent No. is that the utility model of CN99222668.6 discloses a kind of flip-up style socket protective door, it comprises panel, spring, door closure, pedestal, it is characterized in that being provided with axis hole in the upper end of door closure, the door closure axle is gone here and there mutually with the axis hole on the panel, shutter is contained on the panel, control shutter open spring string is on the door closure axle, and an end of its spring is stuck on the pedestal, and the other end is not in the back of door closure; The lower end of door closure is turned round with the card on being located at panel and is engaged.This technology is because projection and the groove that three peripheries that adopted card on door closure and the panel to turn round clamping close device and shutter have, and solved the technical barrier of waterproof and dustproof, protection against electric shock preferably.But the opening and closing of shutter all need the extra manual operation of people in this utility model, and this makes in the operating process more loaded down with trivial details undoubtedly, in addition, do not have interlock function between the two poles of the earth of this utility model, and the electric shock phenomenon takes place when causing one pole to insert easily.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of one pole latch that can either effectively prevent to insert guide tracked the two poles of the earth socket protective door that two utmost point latches are inserted smoothly.

The technical scheme that the utility model adopted is: guide tracked the two poles of the earth socket protective door; has closing door; the fender bracket compressing tablet; elastic component; it is characterized in that it also comprises rectangle fender bracket with fender bracket compressing tablet pin joint; described rectangular closed door is contained in the cavity that is surrounded by fender bracket compressing tablet and fender bracket; respectively be provided with a cylindrical prominent rafter on two sides of closing door and be provided with convex platform with corresponding two limits of fender bracket jack; the guide rail that two sides are provided with and the rafter of dashing forward is complementary of fender bracket; a pin of described elastic component is fixed on a side of fender bracket, and another pin passes below prominent rafter.

One side of described convex platform is provided with an inclined-plane.

Described elastic component is a spring.

The beneficial effects of the utility model are: prominent rafter and corresponding guide rail thereof in the utility model on the closing door; guaranteed to have only when the both sides of closing door stressed when identical; closing door can be opened; and the convex platform of closing door and elastic component make closing door both sides mutual restriction; when having only one pole to insert; closing door can not be opened, and after plug is extracted, again shutter is closed under the active force of elastic component.

Embodiment

Extremely shown in Figure 6 as Fig. 1; present embodiment has closing door 1; fender bracket compressing tablet 2; elastic component 3; these routine characteristics are that it also comprises rectangle fender bracket 4 with fender bracket compressing tablet 2 pin joints; the closing door 1 of rectangle is contained in the cavity that is surrounded by fender bracket compressing tablet 2 and fender bracket 4; respectively be provided with a cylindrical prominent rafter 1-2 on two sides of closing door 1; closing door 1 is provided with convex platform 1-1 with corresponding two limits of fender bracket jack 4-1; and the side at boss is provided with the inclined-plane; so that plug is when pressing down; produce a horizontal component in the horizontal direction; the guide rail 4-2 that two sides are provided with and the rafter 1-2 that dashes forward is complementary of fender bracket 4; under the active force that plug presses down; closing door 1 can move along guide rail, and the elastic component 3 in the present embodiment is springs, and it has two pin that are acute angle; short pin is " U " shape of sealing; be inserted in a side of fender bracket 4, two long pin pass below prominent rafter 1-2 in addition, under the effect of elastic force closing door 1 are pressed to fender bracket 4.

The operation principle of present embodiment is: when two latches of plug insert fender bracket jack 4-1 simultaneously; closing door 1 can move along the guide rail 4-2 of fender bracket 4 sides; behind translation one segment distance; the inclined-plane of the end contact closing door 1 of latch continues translation by closing door 1; thereby open shutter, make two latches of plug insert fender bracket jack 4-1 simultaneously smoothly.When two latches of plug are transferred to,, the torsion of elastic component 3 closes shutter owing to making closing door 1 be returned to reset condition along guide rail.

When the single latch of plug inserts any one shutter jack 4-1; rotate at closing door 1 center around prominent rafter 1-2 under the effect of latch; under one side direction of closing door 1; opposite side upwards; and the convex platform 1-1 of a side that makes progress catches on fender bracket jack 4-1; thereby closing door 1 can not moved along the guide rail 4-2 of fender bracket 4 sides, also just can not open shutter and allow single latch insert fender bracket jack 4-1.
