If the patent No. is disclose a kind of door lock of elevator in the openly Chinese utility model patent document of 201020114670.3, it comprises lock box, be located at the contact in lock box and lower latch hook, correspondingly with lower latch hook hook tight upper latch hook, be located at the bottom roller of latch hook end side, with the latch hook base plate of bottom roller side center shaft Joint, upper roller center shaft one end and upper latch hook ending vertical riser upper end fix, the lower end of vertical wall can be rotated with bottom roller side center shaft and be contacted, bottom roller center shaft between the front end of latch hook base plate and upper latch hook end establishes a torsion spring, the head end card of described torsion spring hangs over latch hook and vertical wall joint portion, the end card of described torsion spring hangs on latch hook base plate.
Above-mentioned door lock of elevator when mounted, be fixed on layer door upper sill frame with the lock box of lower latch hook in its structure, latch hook base plate with upper latch hook is fixed on active layers door strap, being shunk by door cutter movable blades when layer door is normally opened moves on door lock, bottom roller, latch hook is lifted, lower latch hook deviate from by upper latch hook makes layer door open, if layer door is unnormal unlocking, such as external force hand takes off layer door, at this moment because retiring cam is not operating, therefore go up between latch hook and lower latch hook all the time in locking shape, layer door is effectively avoided to be opened by external force, but above-mentioned door lock of elevator still has significantly not foot point, after above-mentioned door lock of elevator being installed in the layer door system of elevator, there is not any safety locking mechanism between two layer door hanging plates in layer door system, that is elevator landing door system uses long-time or artificial destruction occurs, after shackle line between two layer door hanging plates breaks, the one-sided layer door be fixed on driven layer door hanging plate can easy to doly be pushed aside by external force, whole elevator landing door system is made to there is use safety hidden danger.
Therefore, applicant thinks and is necessary to make further structural development to above-mentioned existing elevator door lock device.
Utility model content
The purpose of this utility model be in order to solve above-mentioned the deficiencies in the prior art provide a kind of use in elevator landing door system after, a pair layer door hanging plate in elevator landing door system can be locked, synchronously layer door hanging plate and upper bank base plate can be carried out again the elevator door lock device of locking.
To achieve these goals, a kind of elevator door lock device designed by the utility model, comprise the latch hook base plate be fixed in elevator landing door on any layer door hanging plate, the locking bolt being hinged to the latch hook on above-mentioned latch hook base plate and being fixed on another layer door hanging plate, the hook head portions of above-mentioned latch hook is fixed with pin, the upper bank base plate of above-mentioned elevator landing door is fixed with switch baseplate, this switch baseplate is formed with inclined-plane and is positioned at the first one-sided breach of this inclined-plane, the inclined-plane of above-mentioned switch baseplate and the first breach all drop on the running orbit of above-mentioned pin, and when a pair above-mentioned layer door hanging plate carries out closed, above-mentioned pin falls in the first breach along the inclined-plane on switch baseplate, and synchronous and locking bolt interlocks.
Above-mentioned middle provided a kind of elevator door lock device, latch hook in its structure and locking bolt lay respectively on different layer door hanging plates, upper bank base plate has installed switch baseplate, and when a pair above-mentioned layer door hanging plate carries out closed, synchronous and switch baseplate and locking bolt interlock by pin for the hook head portions of above-mentioned latch hook.
As a kind of technological selection, the pin on the hook head portions of above-mentioned latch hook and the interlocking structure of locking bolt are: described locking bolt is provided with the second breach, and the first breach on this second breach and above-mentioned switch baseplate overlaps; When a pair above-mentioned layer door hanging plate carries out closed, above-mentioned pin synchronously falls in the first breach and the second breach along the inclined-plane on switch baseplate.
In above-mentioned technological selection scheme above-mentioned latch hook hook head portions on pin and the interlocking structure of locking bolt simple, locking good stability.
A kind of elevator door lock device that the utility model obtains, after it uses in elevator landing door system, a pair layer door hanging plate in elevator landing door system can be locked, synchronously layer door hanging plate and upper bank base plate can be locked again, thus make lift car not when elevator floor stops is stopped, whether the shackle line no matter between two layer door hanging plates breaks because of use problem, layer door corresponding on this stop all cannot be pushed aside by external force is rigid, hoisting elevator safety in operation, ensures the security of the lives and property of user.
