The specific embodiment

The present invention is further illustrated below in conjunction with accompanying drawing.

As shown in Figure 1 to Figure 3, elevator lift car door lock synchronization door edge of the present invention, its structure is that it comprises a tool arm 1, door tool arm 22, door tool arm 36, driving gate cutter mount pad 3, driven door cutter mount pad 8, swing arm 20 and latch hook 4; Described door tool arm 1, door tool arm 22, door tool arm 36 are arranged in parallel, and described door tool arm 22 is arranged between a tool arm 1 and door tool arm 36; The left end of described driving gate cutter mount pad 3 is articulated in the top of described door tool arm 1, the right-hand member of driving gate cutter mount pad 3 is articulated in the top of described door tool arm 36, the left end of described driven door cutter mount pad 8 is articulated in the middle and lower part of described door tool arm 1, the right-hand member of driven door cutter mount pad 8 is articulated in the middle and lower part of described door tool arm 36, and described door tool arm 1, door tool arm 36, driving gate cutter mount pad 3 and driven door cutter mount pad 8 form four-bar linkage; The left end of described latch hook 4 is articulated in the middle and upper part of described door tool arm 22, the middle part of latch hook 4 is articulated in the middle and upper part of described door tool arm 36, the left end of described swing arm 20 is articulated in the bottom of described door tool arm 22, and the right-hand member of swing arm 20 is articulated in the bottom of described door tool arm 36; Described door tool arm 22, door tool arm 36, latch hook 4 and swing arm 20 form four-bar linkage; The right-hand member of described latch hook 4 is provided with the clasp that the snap close 19 with gate door machine bottom board is complementary.

Further, the bottom of described door tool arm 22 is provided with the support 11 of unblanking, and conveniently by other instruments, stirs the support 11 of unblanking, and forces a tool arm 2 22 rotations, thereby opens gate.Further, the upper and lower of described door tool arm 36 is provided with rubber block 9, has both played and has prevented that a tool arm 36 and door tool arm 22 from colliding and damaging, and takes again effect spacing and the reduction noise to.Further, described driving gate cutter mount pad 3 and driven door cutter mount pad 8 are provided with back-up ring 7, and back-up ring 7 is arranged at the relevant position of jointed shaft, and the effect of back-up ring 7 is after axle and bearing install, and prevents that axle from separating with bearing.

Elevator lift car door lock synchronization door edge of the present invention, its principle of work is:

When gate is opened, door machine Timing Belt drives driving gate cutter mount pad 3 left-hand revolutions, at first tool arm 1 and door tool arm 36 shrink, driving simultaneously door tool arm 22 shrinks, door tool arm 1 and door tool arm 22 inner clip Room every balls, croquet is opened Room door lock, door tool arm 1 and door tool arm 36 form interlock with driving gate cutter mount pad 3, driven door cutter mount pad 8 simultaneously, the latch hook 4 of gate lock breaks away from snap close 19, electrical contact and touch base disconnect simultaneously, and door tool arm 1 is synchronizeed and opened the door with door tool arm 22 drive Room every balls.

When the door machine at closing time, before closing the door on earth, door tool arm 1 and door tool arm 36, door tool arm 22 still remain retracted, with Room door, be in engagement, after door-closing in-place, the door cutter is when door-closing in-place, door tool arm 1, door tool arm 36, door tool arm 22 open the engagement of exiting with Room door, the latch hook 4 of gate lock meshes with snap close 19 under gravity and extension spring effect simultaneously, by interlock mechanism, gate is locked simultaneously to the closed conducting of gate lock contact and touch base.

When the door machine during at non-flat stratification, the latch hook 4 of gate lock pins with snap close 19, can't open gate, can effectively prevent from gate being opened at the non-level position of elevator by personnel in car, in the up-and-down movement process or other disturb enabling signal maloperations and gate opened, thereby the personnel in car of stopping take off the fall potential safety hazard of hoistway of door when non-level position.

When the door machine during at level position, if the people takes off door in car, the door cutter will move with door-plate, when Room every ball knocked a tool arm 22, it moved downward in the four-bar linkage formed with swing arm 20, door tool arm 36, at first force the latch hook 4 of gate lock to break away from snap closes 19, while continuing again to take off, Room every ball rotation, open Room door lock, and in stranded car, personnel can save oneself.

When the door machine during at level position, in outage in emergency circumstances, can open Room door lock by triangular key, push the about 40mm of Room door aside, now see through the support 11 of unblanking that crack between a door and its frame can be seen a cutter, stir by other instruments the support 11 of unblanking, force a tool arm 22 rotations, the latch hook 4 of gate lock breaks away from snap close 19, and electrical contact and touch base disconnect simultaneously, and gate is pushed aside.

In sum, elevator lift car door lock synchronization door edge of the present invention, by door cutter and the design of door lock integral type, be applicable to elevator normal switch door, level position is saved oneself or cut off the power supply the situation such as open the door, non-level position prevents from opening the door, have simple in structure, convenient for installation and maintenance, can stop the advantage of potential safety hazard.

The above is only preferred embodiments of the present invention, therefore all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in patent claim of the present invention.
