Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Referring to attached drawing 1-3, a kind of latching device of elevator door, including lock crook plate 5 and lock hook seat 6, lock crook plate 5 and latch hook Seat 6 is bolted on respectively in the left hanging plate 1 and main frame plate 2 of layer door, and is formed with fore shaft 12 therebetween.Left hanging plate 1 Latch hook body 4 is equipped with, latch hook body 4 is rotatablely connected by bearing fit shaft and left hanging plate 1；When latch hook body 4 is in water During level state, with 12 snapping of fore shaft, two are realized by way of this self-locking just for the one end of latch hook body 4 away from left hanging plate 1 The closure of layer door-plate 3.

Referring to attached drawing 2, latching device further includes to promote the unlocking component 7 of latch hook body 4 and 12 uncoupling of fore shaft, unlocks Component 7 includes drive link group 8 and the force piece 9 for driving drive link group 8；If necessary, force piece 9 can pass through drive link group 8 driving latch hook bodies 4 rotate clockwise and depart from fore shaft 12.

With reference to attached drawing 4, above-mentioned force piece 9 includes the sleeve 91 being arranged on layer door-plate 3, and sleeve 91 vertically wears a layer door-plate 3, the disc-shaped structure in one end away from drive link group 8, and push against the leading flank of layer door-plate 3；It is also threaded on sleeve 91 Clamp nut 92, clamp nut 92 push against the inside of layer door-plate 3 by gasket, so as to which sleeve 91 is fixed on layer door-plate 3.

Level is equipped with lock core shaft 93 in sleeve 91, clamp spring 94 is connected in lock core shaft 93, and lock core shaft 93 passes through clamp spring 94 push against sleeve 91 close to the end face of drive link group 8；Lock core shaft 93 is away from one end of drive link group 8 integrally formed with the portion of being screwed on 931, perpendicular to the section of its length direction structure triangular in shape in the portion 931 that is screwed on, and 93 integral level of lock core shaft is arranged in set In cylinder 91, and formed and be rotatablely connected with sleeve 91.

To improve the stability of lock core shaft 93, inner slide 95 is embedded in above-mentioned sleeve 91；Inner slide 95 is in sleeve 91 Sliding is set, and level offers to wear the upper delthyrium 951 in the portion of being screwed on 931 on inner slide 95；Inner slide 95 is covering The portion of being screwed on 931 can be effectively supported in cylinder 91, so as to improve the stability of the movement of lock core shaft 93.

With reference to attached drawing 5, to prevent inner slide 95 from coming off from lock core shaft 93, the above-mentioned portion 931 that is screwed on is away from drive link group 8 one The end at end is extended with card edge 932, and card edge 932 is in abut setting away from the end face of drive link group 8 with inner slide 95.

To realize the reset of inner slide 95, above-mentioned inner slide 95 is equipped with the first compression spring 96 close to 8 one side of drive link group, First compression spring 96 is sheathed in the portion of being screwed on 931, and its both ends pushes against 91 inner wall of sleeve and inner slide 95 close to transmission respectively The end face of bar group 8.After energency-unlocking is completed and triangular key is extracted, the first compression spring 96 can reversely promote inner slide 95 so that inner slide 95 blocks triangular key hole again, and protection triangular key hole is against damages.

Referring to attached drawing 2 and attached drawing 4, drive link group 8 includes swing rod 81 and locking bar 82；Wherein, one end of locking bar 82 is sheathed on Lock core shaft 93 deviates from the end of layer door-plate 3；The both sides of locking bar 82 are equipped with locking nut 10, and two groups of 10 equal screw threads of locking nut connect It is connected in lock core shaft 93, and pushes against the both sides of locking bar 82 respectively；Also, locking bar 82 and 93 connecting place of lock core shaft also correspondence form For the notch being mutually located, so as to fulfill being fixedly and coaxially connected for locking bar 82 and lock core shaft 93.The upper end of swing rod 81 passes through spiral shell Bolt is fixedly connected with latch hook body 4, and the lower end of swing rod 81 is mutually abutted with locking bar 82.

In work, when artificially rotating lock core shaft 93, lock core shaft 93 can drive locking bar 82 to rotate synchronously, and locking bar 82 can lead to It crosses swing rod 81 and promotes 4 synchronous hunting of latch hook body so that the uncoupling of latch hook body 4 and fore shaft 12, and then realize energency-unlocking.

With reference to attached drawing 6, buckling groove 911 is formed inside above-mentioned sleeve 91；When artificial inwardly pushing lock cylinder axis 93, lock core The portion 931 that is screwed on axis 93 is embedded at close to the end of drive link group 8 in buckling groove 911 just, and is locked further turn It is dynamic；In this way, after latch hook body 4 and 12 uncoupling of fore shaft, rescue personnel can be screwed on portion 931 with being clamped taking human as control Slot 911 is clamped, and is avoided 4 accidental counter rotation of latch hook body and is caused latch hook body 4 and fore shaft 12 again snapping.

Referring to attached drawing 7, after energency-unlocking is completed, to realize the reset of latch hook body 4, above-mentioned latch hook body 4 and left extension Bending forming has upper folded plate 41 and lower flap portion 101 respectively on plate 1；When latch hook body 4 and fore shaft 12 are in buckle state, upper folding Plate 41 is set in parallel with lower flap portion 101, and is equipped with that latch hook body 4 is promoted to reset between upper folded plate 41 and lower flap portion 101 Reset assembly 11.

With reference to attached drawing 8, reset assembly 11 includes bolt and nut group 111 and second and compresses spring 112；Wherein, bolt and nut Group 111 wears folded plate 41 and lower flap portion 101 simultaneously；Also, it is to wear bolt and nut group 111, it is vertical on above-mentioned upper folded plate 41 Offer kidney slot 411.The upper folded plate 41 of the locking of bolt and nut group 111 and lower flap portion 101, the second compression spring 112 are sheathed on spiral shell In bolt nut group 111, and its upper and lower ends pushes against folded plate 41 and lower flap portion 101 respectively.

In use, after completing energency-unlocking and being screwed on portion 931 and the disengaging clamping of buckling groove 911, the second compression spring 112 Meeting reverse push moveable lock hook body 4 so that latch hook body 4 rotates counterclockwise, and recovers snapping with fore shaft 12.

The operation principle of the present embodiment is：When the generation state of emergency causes elevator out of service, rescue personnel can incite somebody to action In triangular key insertion sleeve 91, triangular key can inwardly promote inner slide 95, so that triangular key passes through triangle thereon The hole of shape is socketed with the portion of being screwed on 931；At this point, rescue personnel can rotate lock core shaft 93 by triangular key, lock core shaft 93 can lead to It crosses locking bar 82 and swing rod 81 promotes latch hook body 4 to rotate clockwise, and realize energency-unlocking.

After latch hook body 4 and fore shaft 12 depart from snapping, rescue personnel can inside pushing lock cylinder axis 93 so that be screwed on portion In 931 end insertion buckling groove 911, prevent lock core shaft 93 from rotating backward, so that latch hook body 4 can be grown with fore shaft 12 Time keeps uncoupling state, convenient for rescuing stranded passenger.

After triangular key is extracted, the first compression spring 96 reversely can promote inner slide 95 to reset, and block three again Angle keyhole；Meanwhile lock core shaft 93 can and buckling groove 911 depart from be clamped, latch hook body 4 under the action of reset assembly 11 with lock Mouth 12 recovers snappings.

This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but As long as it is all protected in the right of the utility model be subject to Patent Law.
