Description
Technical field
The utility model relates to a kind of lockset, particularly a kind of mechanical door lock.
Background technology
Door lock has a plurality of parts such as main hyoplastron and labella, in order in lock housing, to support and install the outward appearance that a plurality of parts can not destroy lock housing again, general door lock all is provided with a bigger backing plate in the bottom of lock housing, backing plate and lock housing are only riveted with lock housing on the lock core next door or are welded together, and more a plurality of parts are installed on backing plate.Such as a kind of door lock is arranged, 3 bearing pins have been adorned in its riveting on backing plate, and one with the horizontal mobile guide of the hyoplastron of deciding with the fanning strip return spring is installed, and one is used to install main hyoplastron braking spring, the rotating shaft as the labella driving chip; Because these 3 bearing pin phase mutual edge distances are distant, so the area of backing plate will be done greatlyyer; In addition owing to independently bring structure complicated on 3 bearing pin functions: its lock core drives a slice fanning strip earlier, and fanning strip removes to drive main hyoplastron by a roller again, and safeguard is transformed into reciprocating motion to rotatablely moving of stop button by an inclined-plane especially.The number of spare parts of this lock is more and size part is bigger, and raw materials consumption is more, is necessary to improve.
The utility model content
The purpose of this utility model is to provide the automatic door lock of a kind of compact conformation, saving material, the saving energy.
The utility model comprises lock housing, lock core, main hyoplastron, labella, and labella driving chip, handle are dialled plate, and safety plate and backing plate, backing plate are fixed in the lock housing; It is characterized in that described main hyoplastron has main hyoplastron drive hole and collision block, described handle is dialled plate and is penetrated main hyoplastron drive hole, and described backing plate has a bearing pin, and the slotted hole of main hyoplastron is enclosed within outside the bearing pin; Described labella driving chip has ratchet and pushes away edge, and ratchet is near the collision block on the main hyoplastron, pushes away edge and is positioned at handle and dials on the plate rotation path; The labella driving chip is hinged on the bearing pin; Having a back-moving spring to be biased in handle dials between plate and the lock housing.
As further improvement of the utility model, safety plate has hook, and safety plate is installed on the lock housing with stop button is coaxial; Main hyoplastron has clubfoot, and the rotary motion trace of hook and the motion track of clubfoot intersect.
The utility model only is equipped with a unique bearing pin on backing plate, make the area of backing plate do very for a short time; The slotted hole of main hyoplastron is enclosed within the outer dependence as translation of bearing pin, and the labella driving chip also is hinged on this bearing pin, has replaced two original special-shaped torsion springs with an extension spring in addition, makes the structure of lock become compact more.
The utlity model has labella automatic blocking function, can also be in outdoor lock chamber, easy to use outside indoor lock chamber, theftproof is strong, uses on the suitable gate that is installed in owned building.

The specific embodiment
Embodiment comprises lock housing 1, lock core 2, by lock core lug 19, main hyoplastron 3, the labella 4 that lock core 2 drives, labella driving chip 5, is enclosed within lock core 2 handles outer and that be connected with handle 20 and dials plate 6, safety plate 7 and backing plate 8.
Referring to Fig. 1 and Fig. 2, backing plate 8 bends out the round bar that one section wall is used to install labella 4, and backing plate 8 is riveted tightly by a bearing pin 11 and is fixed in the lock housing 1, and decorated lid 23 covers in the outside of lock housing 1 in the riveting point; Safety plate 7 is installed on the lock housing 1 by axle 21 with stop button 17.
Referring to Fig. 3, main hyoplastron 3 has main hyoplastron drive hole 9, slotted hole 12, collision block 10 and clubfoot 18, and handle is dialled plate 6 and penetrated main hyoplastron drive hole 9, and the slotted hole 12 of main hyoplastron 3 is enclosed within outside the bearing pin 11 winner's hyoplastron 3 can be horizontally slipped; Labella driving chip 5 has ratchet 13 and pushes away edge 14, ratchet 13 is near the collision block 10 on the main hyoplastron 3, can oppress ratchet 13 inclined-planes when collision block 10 moves to left makes ratchet 13 rises and labella driving chip 5 is rotated counterclockwise, push away edge 14 and be positioned at handle and dial on the rotation path of plate 6, dial plate 6 when handle and run into and labella driving chip 5 is rotated counterclockwise when pushing away edge 14; Labella driving chip 5 is hinged on the bearing pin 11; There is a back-moving spring 15 to be connected handle and dials between the carbine 22 of the aperture of plate 6 and lock housing 1, make main hyoplastron 3 always try hard to stretch out lock housing 1 to the right.
Referring to Fig. 4, with key rotation lock core 2 or directly turn handle when dialling plate 6 and clockwise rotating, main hyoplastron 3 moves to left, collision block 10 lifts ratchet 13, after collision block 10 is crossed ratchet 13, labella driving chip 5 resets under the labella spring action, and ratchet 13 falls and blocks collision block 10 and make main hyoplastron 3 rest on the enable possition, and at this moment key and handle 20 can not return stubborn.If at this moment compress labella 4 from the outside, thereby labella driving chip 5 will rotate counterclockwise ratchet 13 is risen, and discharges collision block 10 again, main hyoplastron 3 locking under the pulling force of back-moving spring 15.
Referring to Fig. 5, under Fig. 4 state, continue to clockwise rotate lock core 2 or directly turn handle when dialling plate 6, handle is dialled the edge 14 that pushes away that plate 6 continues rotation and then pushing labella driving chip 5 rotates counterclockwise labella driving chip 5, and labella driving chip 5 is stirred labella 4 and moved to left and open labella 4.
State when Fig. 6 and Fig. 7 illustrate safety plate 7 and turn to safety position, the afterbody of safety plate 7 has hook 16; Main hyoplastron 3 has clubfoot 18, and the motion track of the rotary motion trace of hook 16 and clubfoot 18 intersects.
Among Fig. 6, safety plate 7 had not turned to safety position when main hyoplastron 3 was opened, and at this moment the hook 16 of safety plate 7 is in and makes main hyoplastron 3 can not continue to move to left on the path that main hyoplastron 3 is moved to the left to play the effect unblanked forbidden.Among Fig. 7, open back safety plate 7 at main hyoplastron 3 and just turn to safety position, hook 16 retainings of safety plate 7 can not give prominence to outside the lock housing 1 main hyoplastron 3 on the right-hand of clubfoot 18, conveniently open the door from indoor.
The area of the backing plate 8 of present embodiment only be traditional automatic door lock the backing plate area 1/10th, the area of safety plate 7 only be traditional automatic door lock the safety plate area 1/3rd, add and cancelled fanning strip, roller, roller shaft and two parts such as bearing pin, make whole automatic door lock weight saving 1/3rd, saved steel, reduced cost.
