As preferably, described door lock plastics be in the middle of the bulge loop of hollow, bulge loop projection down, sticks in the through hole of installing plate A, convex ring edge marginal zone has chamfering, and bulge loop projection length is less than the thickness of installing plate A.
As preferably, described stopping means be in the middle of the bulge loop of hollow, upward, bulge loop inside is provided with inner chamber to described bulge loop projection, described intracavity bottom has vertical disc, described vertical disc is the up big and down small round table surface of round platform radius above.
Use technical scheme of the present invention, design ingenious, novel structure, latch hook contact and disengaging contact are all very convenient, safe and reliable.
Brief description of the drawings
Fig. 1,2, the 3rd, structural representation of the present invention;
Fig. 4 is the structural representation of embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment
As Fig. 1, 2, a kind of door lock of elevator latch hook structure shown in 3, comprise lock crook plate 4 and latch hook installing plate 21, described lock crook plate 4 front portions are provided with latch hook A5, lock crook plate 4 rear portions are rotatably mounted on the side of latch hook installing plate 21, the vertical plane of the vertical plane of described lock crook plate 4 and latch hook installing plate 21 leaves spacing, lock crook plate 4 tops are provided with installing plate A7, described installing plate A7 below is provided with installing plate B22, described installing plate B22 is in latch hook installing plate 21 front end surface, between described installing plate A7 and installing plate B22, be provided with stopping means 13, installing plate B22 bottom is installed with screw 9, described screw 9 sees through installing plate B22 and sees through installing plate A7 successively through door lock plastics 14 through stopping means 13, spring base 8, spring 12, spring base 8 and nut, installing plate A7 front bottom end is provided with contact mount pad C6, described contact mount pad C6 front bottom end is provided with movable contact A2, installing plate B22 below is provided with in order to spacing gear screw 10, lock crook plate 4 rear portions are arranged on latch hook installing plate 21 by bearing block 24, lock crook plate 4 rear portions upwards extend outward installing plate C23, bearing block 24 is outwards provided with the spacing collar 25, on described installing plate C23 and the spacing collar 25, pulley is all installed, pulley is the use in order to coordinate a cutter.
Described door lock plastics 14 are bulge loops of middle hollow, and bulge loop projection down, sticks in the through hole of installing plate A7, and convex ring edge marginal zone has chamfering, and bulge loop projection length is less than the thickness of installing plate A7.
Described stopping means 13 is bulge loops of middle hollow, described bulge loop projection upward, bulge loop inside is provided with inner chamber, described intracavity bottom has vertical disc, and described vertical disc is the up big and down small round table surface of round platform radius above, and vertically disc is because one section of vertical cylindrical hollow out is arranged at bottom, round table surface is through truncated cone-shaped hollow out, round platform radius is up big and down small, is for fear of screw 9 frictions too much like this, affects life of product.
As shown in Figure 4, described plug-assembly comprises plug fixed head 11, connector assembly 29 and plug 15, connector assembly 29 attachment plug fixed head 11 and plug 15 respectively, plug 15 is metals, be used for the fixed contact of make contact mount pad B17, described switch module comprises mounting base 16 and containment vessel 28, described mounting base 16 lower face are provided with contact mount pad A18, movable contact A20 is towards the right side, mount pad A18 below in contact is provided with latch hook B19, described latch hook B19 surface is provided with at right angle setting plate 27, described at right angle setting plate 27 vertically one side is provided with contact mount pad B17, contact mount pad A18 lateral surface is provided with rubber slab, insulate safer, contact mount pad A18 is positioned at containment vessel 28, play the effect of guard block, contact mount pad A18 is connected by electric wire with contact mount pad B17.
