Abstract

The utility model relates to a vertical middle division door lock for a dumb waiter. The vertical middle division door lock comprises a lock knife and a fixed lock plate assembly. The fixed lock plate assembly comprises a lock plate, a lock hook, an electromagnet, a connection rod, a switch moving contact and a switch fixed contact. The electromagnet is located at the lower portion of the lock plate, an electromagnet mandrel is arranged at the bottom of the electromagnet, the electromagnet mandrel is connected to one end of the connection rod, and a reset spring is arranged on the electromagnet mandrel. The other end of the connection rod is connected with the lower left corner of the lock hook in a rotating mode through a connecting shaft, the lower right corner of the lock hook is connected to the lock plate in a rotating mode through the fixed shaft, and a switch moving contact is arranged in the middle of the lock hook. The vertical middle division door lock for the dumb waiter has the advantages of being simple in structure and enabling a mechanical lock to be in linkage with an electrical appliance verifying switch. The non-synchronous of the mechanical lock and the electric appliance verifying switch is avoided, and safety performance of the dumb waiter side opening door lock is improved.

The specific embodiment

As shown in Fig. 1-7, a kind of dumb waiter vertical centering control described in the utility model embodiment divides door lock, comprises lock cutter 1 and fixing jam plate assembly, and the behind of described lock cutter 1 is provided with pulls pin 14, the below on described lock cutter 1 right side is provided with stud 10, and described stud 10 tops are provided with opening; Described fixedly jam plate assembly comprises that jam plate 3, latch hook 2, electromagnet 5, connecting rod 7, switch movable contact 4 and switch determine contact 12, described electromagnet 5 is positioned at the bottom of jam plate 3, the bottom of described electromagnet 5 is provided with electromagnet mandrel 13, described electromagnet mandrel 13 is connected to one end of connecting rod 7, and described electromagnet mandrel 13 is provided with retracing spring 9; The other end of described connecting rod 7 is by adapter shaft 8 rotary connections in the lower left corner of latch hook 2, and the lower right corner of described latch hook 2 is by anchor shaft 6 rotary connections on jam plate 3, and the middle part of described latch hook 2 is provided with switch movable contact 4; The middle part in described jam plate 3 left sides is provided with flap, and described flap is provided with switch and determines contact 12, and the below and the right side that on described jam plate 3, are positioned at latch hook 2 are equipped with noise reduction rubber cushion 11.

The position that described switch movable contact 4 is determined contact 12 with switch is corresponding, and cooperatively interacts.

During installation, lock cutter be fixed on the upper door leaf of vertical center opening door, slide up and down together with upper door leaf, fixedly lock pull assembly be arranged on door slideway on, position maintains static.

During use, when upper door leaf and Xiamen need to be closed, the stud 10 of lock cutter 1 touches latch hook 2, and when upper and lower door leaf is gradually near to after cutting out, under the combined action of gravity and retracing spring 9, the upper of latch hook 2 directly snaps fit onto on stud 10.Switch movable contact 4 on latch hook 2 is determined contact 12 connections with switch simultaneously, and elevator can carry out call operation.When upper door leaf and lower door leaf need to be opened, electromagnet 5 energisings, shrink electromagnet mandrel 13, drivening rod 7 is upwards transported merit, and then be with moveable lock hook 2 to do clockwise rotation around anchor shaft 6, and the locked groove of latch hook 2 upper ends shifts out from the stud 10 of lock cutter 1, and mechanical lock is opened; Simultaneous Switching moving contact 4 leaves switch and determines contact 12, switch circuit breaking.Mechanical lock and electrical equipment checking synchro switch have been guaranteed.
