Abstract
The invention discloses two kinds of mechanical releasers which are applied to the socket of electric leakage protection. The releasers are composed of a releaser, a lock, a spring, and a release-bar. The release is a cylinder with a vertical hole on the top. There is a movable 'L' typed clasp across the release at the bottom. There is a hole on the top surface of the lock. There is a spring between the walls of the lock and the releaser. There is a hole on the top surface of the lock and a release-bar goes through the hole. The release-bar of the first mechanical releaser is '7' typed which locates under the test button of the socket of electric leakage protection. The head of the button pulls the release-bar downward till it is released when the test button is pressed. The release-bar of the second releaser turns around the fulcrum and pulls the lock moving till releasing when the test button is pressed.

Embodiment
As shown in Figure 1, the mechanical trip gear that is applied in the earth leakage protective socket (being called for short GFCI) disclosed by the invention is made of release 1, snap close 2, spring 3 and dropout lever 4.
In the bottom of release 1, cross release 1 and be provided with " L " type snap close 2 of movably making by metal material; It crosses the bottom of release 1, and to carry arm vertical with release 1 both sides.End face at snap close 2 is provided with a perforation 8.Between the sidewall of the sidewall 9 of snap close 2 and release 1, be provided with a spring 3.Be provided with a through hole 10 in the end of snap close 2 end faces, in through hole 10, be installed with the dropout lever 4 of one " 7 " font.
Between the sidewall of the sidewall of release 1 and dropout lever 4, on the sidewall of release 1, be provided with a leg-of-mutton fulcrum 11, dropout lever 4 can rotate around this fulcrum 11.
Described release 1, snap close 2, spring 3 and dropout lever 4 are interconnected to constitute one can free movable linkage.
As Fig. 2, shown in Figure 4, when above-mentioned mechanical trip gear was assembled in the earth leakage protective socket, release 1 was positioned at the below of earth leakage protective socket reset button 12, and the guiding lock 13 that is embedded in reset button 12 bottoms passes the through hole 5 at release 1 top, can move up and down.
The sidewall 9 of snap close 2 that crosses release 1 bottom is relative with iron core 15 in being built in earth leakage protective socket solenoid 14.The end face that passes the dropout lever 4 of snap close 2 top end through holes 10 be positioned at earth leakage protective socket test button 16 under.
As Fig. 2, shown in Figure 3; leak current fault appears in power supply circuits and the inner original paper of earth leakage protective socket breaks down and can't make earth leakage protective socket dropout/tripping operation; when cutting off its electric power output; the user can exert all one's effort to push test button 16 downwards, and the head compressing dropout lever 4 of test button 16 moves downward.Because snap close 2 is connected mutually with dropout lever 4; constitute a mobilizable linkage; so; snap close 2 just is moved to the left by 4 pullings of dropout lever; thereby the guiding lock 13 of reset button 12 bottoms is deviate from from the perforation 8 of snap close 2 end faces; release 1 falls; make and be placed on the elastic sheet metal of carrying in the earth leakage protective socket on the arm release 1 both sides and fall; fixed contact end on moving contact on it and the power supply output conductor is opened; and then make earth leakage protective socket power supply output conductor not charged; realize the tripping operation/dropout of earth leakage protective socket, cut off the electric power output of earth leakage protective socket.After finishing machinery dropout, release test button 16, mechanical trip gear is returned to original position under the effect of spring 3.
Fig. 5～Fig. 7 is the cutaway view of the mechanical trip gear of another kind disclosed by the invention.As shown in the figure, this mechanical trip gear is made of release 1, snap close 2, spring 3, dropout lever 4, dropout push rod 17 and a back-moving spring 18.
In the bottom of release 1, cross release 1 and be provided with " L " type snap close 2 of movably making by metal material; It crosses the bottom of release 1, and to carry arm vertical with release 1 both sides.End face at snap close 2 is provided with a perforation 8.Between the sidewall of the sidewall 9 of snap close 2 and release 1, be provided with a spring 3.Be provided with a through hole 10 in the end of snap close 2 end faces, in through hole 10, be installed with a dropout lever 4.
Between the sidewall of the sidewall of release 1 and dropout lever 4, on the sidewall of release 1, be provided with a triangle fulcrum 11, dropout lever 4 can rotate around this fulcrum 11.
On the push rod of dropout push rod 17 sides, be with a back-moving spring 18.
Described release 1, snap close 2, dropout lever 4 and spring 3 constitute one can free movable linkage.
As shown in Figure 6; leak current fault appears in power supply circuits and the inner original paper of earth leakage protective socket breaks down and can't make its dropout/tripping operation; when cutting off its electric power output; the user can exert all one's effort to push test button 16 downwards; make the head of test button 16 head on the inclined-plane of dropout push rod 17; force it to move, thereby, make the push rod of dropout push rod 17 sides promote fulcrum 11 rotations of dropout lever 4 on release 1 sidewall.Because snap close 2 is connected mutually with dropout lever 4; form a mobilizable linkage; so; snap close 2 just is moved to the left by 4 pullings of dropout lever; the guiding lock 13 of reset button 12 bottoms is deviate from from the perforation 8 of snap close 2 end faces; release 1 falls; make and be placed on the elastic sheet metal of carrying in the earth leakage protective socket on the arm release 1 both sides and fall; fixed contact end on moving contact on it and the power supply output conductor is opened; and then make earth leakage protective socket power supply output conductor not charged; realize earth leakage protective socket tripping operation/dropout, cut off the electric power output of earth leakage protective socket.After finishing machinery dropout, release test button, mechanical trip gear is returned to original position under the effect of spring 3, back-moving spring 18.
Two kinds of mechanical trip gears disclosed by the invention all can be finished the machinery of earth leakage protective socket reliably and thread off, and cut off the electric power output of earth leakage protective socket.
The above is specific embodiments of the invention and the know-why used, and is any based on the equivalent transformation on the technical solution of the present invention basis, all belongs within the protection range of the present invention.
