Description
Technical field
The utility model relates to shutter technical field of electric appliances, is specifically related to a kind of shutter.
Background technology
The shutter structure of current market circulation, opens shutter by E pole bolt driving usually.There is certain defect in design in this structure, when user's false touch E pole jack, very easily shutter can be opened, cause live part L/N pole jack unnormal unlocking, the electroshock-proof function of L/N pole jack lost efficacy, do not reach the object of protection against electric shock, most jack assembled arrangement is simultaneously: double-purpose the two poles of the earth jack and three pole insertion hole groups are combined, be commonly called as little five hole combinations, when with E pole bolt driving shutter, also double-purpose the two poles of the earth jack is opened, also the L/N pole jack unnormal unlocking of double-purpose the two poles of the earth jack can be caused, the electrocution-proof protection of the L/N pole jack of double-purpose the two poles of the earth jack is caused to lose efficacy.
In sum, adopt the structure of E pole bolt driving shutter, have certain functional defect, Consumer's Experience is not good, causes product can lose due competitiveness.
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and provides a kind of shutter.
The technical solution of the utility model is as follows:
A kind of shutter, comprises and protects box cover and protection box lower cover, cover the jack being provided with correspondence under described protection box cover and protection box; In described protection box lower cover, position placed in the middle is on the lower provided with three pole shutters, and three shutter upper ends, pole are provided with a pair second joint pins; Be provided with the two poles of the earth double-purpose shutter above described three pole shutters, double-purpose shutter lower end, the two poles of the earth is provided with a pair first joint pins; Described first joint pin is connected by spring with the second joint pin; Entirety is connected into by protection box cover above described protection box lower cover; Described jack is divided into the two poles of the earth jack and three pole jacks
.
Described protection box lower cover side is provided with a pair the 3rd joint pin for being connected with protection box cover.
The utility model beneficial effect is as follows: the utility model adopts the two poles of the earth jack and three pole jacks to be protected by independently shutter respectively; relatively independent in use; non-interference; user can by jack needed for selection; avoid all being opened by all jacks in little five holes because E pole jack drives of traditional protection door; reliably safer when allowing user use; driven by the L/N latch of plug when opening shutter simultaneously; can open; opening ways is science, hommization more, and fail safe is better.
