Abstract
The utility model relates to a novel door lock for a dumbwaiter lift. The novel door lock comprises a lockset connecting plate, a rotating arm, an unlocking wheel, a lock clamping slot and a lock clamp, wherein a reset heavy punch is arranged on the rotating arm and is fixedly connected with an upper end of the rotating arm; the lock clamping slot is arranged on a lower end of the rotating arm; and when a door is locked, the lock clamp is in contact connection with the lock clamping slot. The novel door lock is reset by adopting the heavy punch instead of a traditional spring tension rotating arm, so that the phenomenon that the rotating arm is not reset on the reset heavy punch is avoided, and the use is safer.
Description
Technical field
The utility model relates to a kind of door lock, particularly relates to a kind of dumb waiter new door lock.
Background technology
Traditional dumb waiter door lock adopts the spring tension cursor to reset, and spring loses intrinsic elastic force after stretching after a while, cause cursor not reset, and door lock lost efficacy, and produces dangerous.
Summary of the invention
The purpose of the utility model is exactly the defective to prior art, and a kind of dumb waiter new door lock is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of dumb waiter new door lock comprises: lockset junction plate, cursor, the wheel of unblanking, locking trough, pintle hook lock, and described cursor is provided with the weight that resets, and the weight that resets is fixedly connected with the upper end of cursor.
The lower end of described cursor is provided with locking trough, and pintle hook lock is connected with the locking trough contact when locking a door.
The beneficial effect of the utility model: adopt weight to reset, replace conventional springs pulling force cursor and reset, the phenomenon that arm does not reset because the weight that resets can not rotate is so use safer.
Description of drawings
Fig. 1 is in the schematic perspective view of the state of locking a door that resets for one of them embodiment cursor of the utility model.
Fig. 2 is in the schematic perspective view of unlocking condition for the foregoing description cursor.
Fig. 3 is the sketch map of the foregoing description disassembled.
The specific embodiment
Extremely shown in Figure 3 like Fig. 1; The utility model comprises: lockset junction plate 2, cursor 4, unblank to take turns 13, locking trough 14, pintle hook lock 6, described cursor 4 is provided with the weight 1 that resets, the weight that resets is fixedly connected with the upper end 9 of cursor; Under the action of gravity of the weight that resets; Cursor is rotated by the direction of arrow among Fig. 2 11 all the time, be in reset mode, press the direction of arrow 12 when unblanking.Cursor 4 middle parts flexibly connect through turning cylinder 10 and lockset junction plate 2, and the moving axis swing that can rotate, and lockset junction plate 2 is fixedly connected with elevator door 7, elevator framework 8 respectively with pintle hook lock 6.
The lower end of described cursor is provided with locking trough 14, and pintle hook lock is connected with the locking trough contact when locking a door, and promptly pintle hook lock gets in the locking trough, touches with the inboard edge joint of locking trough to be connected, and makes door obtain the location.
