The internal structure of elevator door lock.
Content of the invention
Technical problem to be solved in the utility model is:There is provided a kind of layer door unlocking apparatus, it solves current electricity
The lock core of terraced layer door is not provided with rotational angle limiting structure, thus leading to the problem that inside is easily damaged.
Technical problem to be solved in the utility model takes technical scheme below to realize:
A kind of layer door unlocking apparatus, it includes lock tube, rubber ring, lock tube nut, lock core, connector, lock core nut, card
Ring, back-moving spring,
Described lock tube inner bottom end surface is provided with stopper slot, and lock tube is externally provided with screw thread, and lock tube passes through the installing hole of layer door, then covers
Upper rubber ring, the fastening of lock tube nut,
Described lock core is made up of triangle lock nut, locking bar, and on locking bar, next-door neighbour triangulation chain cap position is provided with limited block, and locking bar is from layer
Outer side of door penetrates lock tube, and triangle lock nut falls in lock tube, and limited block falls in stopper slot, and stopper slot limits the angle of rotation of lock core
Degree, the locking bar other end passes lock tube position and is provided with draw-in groove, setting snap ring in draw-in groove, and locking bar is axially confined in lock tube by snap ring
In, locking bar end is provided with screw thread, is vertically and fixedly provided with connector by lock core nut, by being enclosed within locking bar between connector and lock tube
On back-moving spring connect.
As preferred embodiment, the span that described stopper slot limits the maximum angle that lock core rotates is 30-120 °.
The beneficial effects of the utility model are:By arranging the stopper slot cooperating and limited block, maintainer is made to open
During lock, perception lock core rotational angle limits, and prevents from blindly reversing damage lock core;Its structure is simple, easy for installation.
Brief description
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of lock tube in this utility model;
Fig. 3 is the structural representation of lock core in this utility model.
In figure:Lock tube 1, rubber ring 2, lock tube nut 3, lock core 4, connector 5, lock core nut 6, snap ring 7, back-moving spring 8,
Stopper slot 9, triangle lock nut 10, locking bar 11, limited block 12, draw-in groove 13.
Specific embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and this utility model is expanded on further.
As shown in Figure 1-Figure 3, a kind of layer door unlocking apparatus, it includes lock tube 1, rubber ring 2, lock tube nut 3, lock core 4, connects
Fitting 5, lock core nut 6, snap ring 7, back-moving spring 8,
Lock tube 1 inner bottom end surface is provided with stopper slot 9, and lock tube 1 is externally provided with screw thread, and lock tube 1 passes through the installing hole of layer door, then covers
Upper rubber ring 2, lock tube nut 3 fasten,
Lock core 4 is made up of triangle lock nut 10, locking bar 11, and on locking bar 11, next-door neighbour triangulation chain cap 10 position is provided with limited block 12,
Locking bar 11 penetrates lock tube 1 from layer outer side of door, and triangle lock nut 10 falls in lock tube 1, and limited block 12 falls in stopper slot 9, stopper slot 9
Limit the rotational angle of lock core 4, locking bar 11 other end passes lock tube 1 position and is provided with draw-in groove 13, setting snap ring 7 in draw-in groove 13, card
Locking bar 11 is axially confined in lock tube 1 ring 7, and locking bar 11 end is provided with screw thread, is vertically and fixedly provided with connection by lock core nut 6
Part 5, between connector 5 and lock tube 1, the back-moving spring 8 by being enclosed within locking bar 11 is connected.
The span that stopper slot 9 limits the maximum angle that lock core 4 rotates is 30-120 °.
Operation principle:When opening layer door, professional passes through special key, twists lock core 4, and band follower link 5 rotates,
Connector 5 drives the hook lock device unblock of elevator door, after maintainer perception lock core 4 turns to limited by maximum angle, stops
Rotate lock core 4, now elevator door be in can open mode, rotational angle limits can be prevented from blindly reversing damage lock core 4;Close
During layer door, by special key, lock core 4 is turned to maximum angle, is then shut off layer door, more gradually loosens private key,
Under back-moving spring 8 effect, connector 5 drives the hook lock device of elevator door to lock two fan layer door, prevents layer door to be opened accidentally.
The scope that stopper slot 9 limits the maximum rotation angle of lock core 4 is 30-120 °, chooses a reality in the range of this
