Abstract
The utility model discloses a multidirection automatic lock which comprises a lock body and a lock core, wherein, the lock core is connected with a crankshaft connecting rod mechanism, the connecting rods of the crankshaft connecting rod mechanism are respectively connected with lock bolts, wherein, one lock bolt and a positioning key form a locking mechanism, the lock bolt is provided with a return spring, a pin hole, and a positioning slot, wherein, a pin post is arranged in the pin hole, and the pin post is arranged on the lock body. The lock bolt passes through the pin hole and move horizontally along the pin post. The positioning key can rotate around a fulcrum, and one end of the positioning key can enter and extract the positioning slot of the lock bolt. The end arm of the positioning key is provided with a return spring. The other end of the positioning key contacts a movable contact arranged in the lock bolt. The movable contact is provided with a return spring.
Description
The utility model relates to a kind of lock, is a kind of multidirectional automatic locking that is used for door, cabinet specifically.
The dead bolt of conventional door, cabinet lock generally is a bevel, and purpose is conveniently to close.But the inclined-plane dead bolt has a shortcoming, pries open easily.If dead bolt is made flat dead bolt, then laying the key under the door must just can make dead bolt stretch out with key turns to lock.
The purpose of this utility model is to provide a kind of lock convenient and the good multidirectional automatic locking of theftproof performance.
To achieve these goals, the utility model adopts following technical scheme: a kind of multidirectional automatic locking, comprise lock body, lock core, it is characterized in that: lock core connects a crankshaft connecting rod system, the connecting rod of this crankshaft connecting rod system is connected with dead bolt respectively, wherein a dead bolt and positioning key are formed a locking mechanism, this dead bolt is provided with back-moving spring, pin-and-hole and locating slot, be provided with pin in this pin-and-hole, this pin is located on the lock body, make this dead bolt do translation along pin through pin-and-hole, positioning key can rotate around fulcrum, and an end of positioning key debouches in the locating slot of dead bolt, and is provided with a back-moving spring on this end arm, the other end of positioning key contacts with armature contact in being located at dead bolt, and this armature contact is provided with back-moving spring.
Good effect of the present utility model is: be provided with an armature contact in the dead bolt, at closing time, as long as armature contact contact doorframe, each dead bolt stretches out automatically, reaches a door leaf pass gently, can automatically lock, and uses easily.Simultaneously, owing to adopt crankshaft connecting rod system to connect a plurality of flat tongue lock points of different directions, thereby have theftproof preferably.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is crankshaft connecting rod system and a dead bolt drive connection structural representation in preferred embodiment of the utility model.
See also shown in the accompanying drawing, the utility model is made up of lock body (not shown), lock core (not shown), crankshaft connecting rod system and dead bolt.Lock body, lock core do not belong to inventive point of the present utility model, so do not elaborate.Crankshaft connecting rod system 10 is connected with lock core; Rotational lock core, i.e. rotatable crankshaft linkage.The connecting rod 11,12,13 of this crankshaft connecting rod system 10 is connected with dead bolt 111,121,131 respectively, and wherein a dead bolt 131 is formed a locking mechanism with positioning key 20, and this dead bolt 131 is provided with back-moving spring 132, pin-and-hole 133 and locating slot 134.Be provided with pin 135 in this pin-and-hole 133, this pin 135 is located on the lock body, makes this dead bolt 131 do translation through pin-and-hole 133 along pin 135.Positioning key 20 can rotate around fulcrum 21, and an end 22 of positioning key 20 debouches in the locating slot 134 of dead bolt 131, and is provided with a back-moving spring 23 on these end 22 arms 25.The other end 24 of positioning key 20 contacts with armature contact 136 in being located at dead bolt 131, and this armature contact 136 is provided with back-moving spring 137.
When the utility model uses, be contained in armature contact 136 in the dead bolt 131 when door is closed, contact 136 contact doorframes, contact 136 compression springs 137 are pushed away inward, one end 24 of pushing tow positioning key 20, make positioning key 20 rotate an angle around fulcrum 21, the other end 22 of positioning key 20 leaves the locating slot 134 of dead bolt 131.Then dead bolt 131 stretches out dead bolt 131 and locks under the promotion of back-moving spring 132.Simultaneously dead bolt 131 drives crankshaft connecting rod systems 10 through connecting rod 13 and rotates an angle, dead bolt 111,121 is together stretched out with dead bolt 131 lock, and multidirectionally lock out automatically thereby reach Men Yiguan.When unblanking, use key rotation lock core, lock core drives crankshaft connecting rod system 10 and rotates an angle, and each dead bolt 111,121,131 is regained, and under the effect of positioning key 20, keeps each dead bolt 111,121,131 at retrieving position.
