Abstract

The utility model discloses a manual protection door structure of a five-hole socket, which comprises a socket panel, a protection door and a protection cover. A pulling block is arranged on the protection door, a sliding groove for the pulling block to vertically slide is arranged on the socket panel, and a location structure enabling the protection door to be located at the specific position is arranged between the protection cover and the protection door. A manual protection door is adopted to replace automatic protection doors which are common on the market at present, so that the manual protection door structure not only is simple in structure, low in design cost and convenient in operation, but also can avoid safety hazards caused by the fact that the automatic protection doors cannot reset after a long time use and improve safety factors of the five-hole socket.

Description

A kind of manual shutter structure of five spring hole scokets

Technical field

The utility model relates to the shutter structure of supply socket, particularly a kind of manual shutter of five spring hole scokets.

Background technology

Shutter also is " emergency exit ", the socket promptly said at ordinary times " safety socket " of band shutter, and insulator is equipped with in the sleeve component top of this socket, need could insert plug with bigger power during use; After plug was pulled out, the insulation physical efficiency automatically reset, and also can not get an electric shock even finger has put in socket aperture because of carelessness, is particularly conducive to and prevents that child from getting an electric shock.

Socket in the market is of a great variety, even some product has shutter, but still can insert with screwdriver or key, because of unreasonable the causing of its shutter design.General technology better and the shutter of National standard needs to adopt anti-one pole to insert design.The two poles of the earth plug has only two pins to insert simultaneously and could shutter be backed down; The anti-one pole of three-terminal polarized plus plug inserts generally has two kinds of designs, and the one, earth electrode unprotect door, fire, zero the two poles of the earth also will be inserted simultaneously just and can be backed down shutter; Second kind is that three utmost points all have shutter, and when grounding pin backed down shutter, fire, zero the two poles of the earth shutter just can be opened.But above-mentioned requirements is to two hole socket and Three-hole socket, for the corresponding standards for safe use of the same needs of five spring hole scokets of two hole socket and Three-hole socket combination; But still there is following defective in the shutter in present five spring hole scokets: when Three-hole socket used, the conducting strip of two hole socket was exposed, and when two hole socket used, the conducting strip of Three-hole socket was exposed; There is potential safety hazard in the user in using the process of supply socket like this, and possibly have foreign matter and fall in the socket.Therefore above-mentioned shutter structure is to satisfy the requirement safe in utilization of plate connectors such as five spring hole scokets.It is CN201020188089.6 that China national Patent Office discloses the patent No. on December 15th, 2010; Name is called a kind of patent that is used for the shutter structure of five spring hole scokets; The disclosed technical scheme of this patent comprises base, pressing plate, shutter, spring, cover group; One end of spring props up shutter, and the other end props up cover; It adopts single piece type independent protective door, realizes the slotting defencive function of porous, is applicable to five spring hole scokets, and the defective of existence is: when one group of jack was opened, another group jack unavoidably also can be opened, and has potential safety hazard.

Summary of the invention

The utility model problem to be solved just provides a kind of manual shutter of five spring hole scokets, adopts the manual operation shutter, and structural design is simple, reasonable, easy to use, overcomes the existing existing defective of five spring hole scoket shutters.

For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of manual shutter structure of five spring hole scokets; Comprise socket panel, shutter and protective cover; It is characterized in that: said shutter is provided with shifting block, and said socket panel is provided with the chute that supplies shifting block to slide up and down, and is provided with the location structure that shutter is positioned at assigned address between said protective cover and the shutter.

Further, described location structure comprises several positioning convex that are located on the protective cover two side, and the shutter both sides are provided with positioning convex and cooperate location notch.

Further, respectively be provided with three positioning convex on the protective cover two side, the shutter both sides respectively are provided with a location notch, and when the positioning convex of protective cover the top engaged with the location notch of shutter, shutter blocked two utmost point jacks of socket; When the positioning convex in the middle of the protective cover engaged with the location notch of shutter, shutter blocked two utmost point jacks of socket and the L/N utmost point jack of three grades of jacks; Protective cover is when the positioning convex of below engages with the location notch of shutter, and shutter blocks the L/N utmost point jack of three utmost point jacks in the socket.

Further, three of corresponding shutter position locations are provided with three gears and indicate the guides user operation on the said socket panel.

Further, said shifting block surface is provided with anti-slip tank.Make things convenient for user's hand push.

The beneficial effect of the utility model: the utility model adopts manual shutter to replace comparatively general automatic shutter in the market, not only simple in structure, design cost is low, easy to operate; And can also avoid automatic shutter because of long-time the use causes the potential safety hazard that can't reset and cause, improved the coefficient of safety of five spring hole scokets.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is the assembling sketch map of the utility model;

Fig. 2 uses sketch map one for the utility model;

Fig. 3 uses sketch map two for the utility model;
