Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, for convenience of description, the lock body 100 of the present invention includes a base 1, a power part 2, a latch 3, a moving plate 4, and a first elastic member 5. The power part 2 is arranged on the base 1, is in transmission connection with the moving plate 4 and is used for driving the moving plate 4 to move. The bolt 3 can move telescopically and is provided with a limiting part 6. The moving plate 4 is arranged on the base 1 in a sliding mode, and the power part 2 is in transmission connection with the moving plate 4 and can drive the moving plate 4 to move. The moving plate 2 is further provided with a sliding groove 41, and the sliding groove 41 includes a first groove section 411 which is obliquely arranged relative to the moving direction of the bolt 3. The limiting part 6 penetrates through the sliding groove 41 to realize linkage of the lock tongue 3 and the moving plate 4. A guide inclined plane 42 parallel to the first slot section 411 or forming a small angle with the first slot section 411 is arranged on one side surface of the moving plate 4. One end of the first elastic element 5 is connected with the lock tongue 3, and the other end of the first elastic element abuts against the side face of the moving plate 4 provided with the guide inclined plane 42. The power unit 2 drives the moving plate 4 to move, and when the latch 3 is pushed to move telescopically, the limiting member 6 moves in the first slot segment 411, and the first elastic member 5 moves on the guide inclined surface 42 by abutting against one end of the side surface of the moving plate 4. During locking, the power part 2 drives the moving plate 4 to move, the first groove section 411 pushes the limiting piece 6 to move, the bolt 3 is driven to extend, and meanwhile, the first elastic piece 5 moves along the guide inclined plane 42; during unlocking, the power portion 2 drives the moving plate 4 to move, the first groove section 411 pushes the limiting piece 6 to move, the lock tongue 3 is driven to contract, and meanwhile, the first elastic piece 5 moves along the guide inclined plane 42. In the whole locking and unlocking process, when the first groove section 411 pushes the bolt 3 to move, the first elastic part 5 synchronously slides on the guide inclined plane 42, and because the guide inclined plane 42 and the first groove section 411 are inclined in parallel or form a small-angle included angle with the first groove section 411, the first elastic part 5 cannot deform or deform less, so that when the bolt 3 is contracted and unlocked, only the friction force between the bolt 3 and a lock hole needs to be overcome, the elastic force of the first elastic part 5 does not need to be overcome or overcome less, unlocking can be performed without large torsion, and unlocking is labor-saving.

As shown in fig. 1, the lock body 100 further includes a second elastic member 7, and the second elastic member 7 is installed on the base 1 and located on the side where the bolt 3 extends; after locking, the second elastic piece 7 is pressed against the door frame to deform. When the door is locked, the bolt 3 is inserted into the keyhole, the door plate is clamped, and the second elastic piece 7 is abutted against the door frame and deforms; when the door is unlocked, the lock tongue is withdrawn from the lock hole, the door plate is loosened, and the second elastic piece 7 is pushed out by the elastic force when being restored to deform. Thus, after unlocking, the door panel can be bounced by the second elastic piece 7, and the door panel is convenient to open.

As shown in fig. 4, the sliding groove 41 further includes a second groove section 412, and the second groove section 412 is parallel to the moving direction of the bolt 3 and smoothly transits to one end of the first groove section 411. In this scheme, when needing to lock again after the unblock, spring bolt 3 and door frame support the atress, and first elastic component 5 is compressed, and spring bolt 3 removes to shrink and drives locating part 4 and slide to in the second groove section 412. After the bolt 3 is aligned with the lock hole, the bolt 3 is inserted into the lock hole under the action of the first elastic piece 5, and the first elastic piece 5 restores to the initial state to complete locking. The moving plate 4 needs to be locked by moving the moving plate 4 by a mechanical key or a motor, and in the present embodiment, the second groove section 412 is provided so that locking can still be realized without moving the moving plate 4, and locking is convenient.

In the present embodiment, the inclined direction of the guide slope 42 is parallel to the inclined direction of the chute 41. Because the guide inclined plane 42 and the sliding groove 41 are inclined in parallel and have the same inclination angle, the first elastic element 5 cannot deform in the moving process of the moving plate 4, so that when the bolt 3 contracts and unlocks, only the friction force between the bolt 3 and the lock hole needs to be overcome, and the elastic force of the first elastic element 5 does not need to be overcome.

Further, the sliding groove 41 further includes a third groove segment 413, and the third groove segment 413 is perpendicular to the moving direction of the locking tongue 3 and is in smooth transition with the other end of the first groove segment 411. When the lock tongue 3 retracts, the moving plate 4 cannot stop moving in time due to inertia effect and the like, and when the moving plate needs to continue moving, the third groove section 413 can play a buffering role, so that the sliding groove 41 and the limiting part 4 are prevented from being excessively worn, and the moving plate 4 is further damaged.

As shown in fig. 5, the locking tongue 3 is provided with an accommodating cavity 31 and a limiting groove 32 penetrating through a side wall of the locking tongue 3, the moving plate 4 passes through the limiting groove 32 and can slide in the limiting groove 32, and the first elastic element 5 is arranged in the accommodating cavity 31 and abuts against between the accommodating cavity 31 and a side surface of the moving plate 4 provided with the guide inclined surface 42. The accommodating cavity 31 can limit the position of the first elastic piece 5, and prevent the first elastic piece 5 from moving left and right to affect the locking or unlocking effect. Preferably, the first elastic member 5 is a spring.

As shown in fig. 6 and 7, the latch bolt mechanism 100 further includes a bolt seat 8, and the bolt seat 8 is provided with a bolt cavity 82 having at least one end opening 81 and a plate slot 83 penetrating through a side wall of the bolt cavity 82. The bolt 3 is arranged in the bolt cavity 82 and can extend out of the opening 81 or retract into the bolt cavity 82; the moving plate 4 passes through the plate groove 83 and is slidable in the plate groove 83.

As shown in fig. 5, one of the tongue cavity 53 and the tongue 3 is provided with a guide protrusion extending along the moving direction of the tongue 3, and the other is provided with a guide groove 13 slidably fitted with the guide protrusion. Specifically, be equipped with guide way 33 on the spring bolt 3, be equipped with the direction arch in the tongue chamber 53, through the cooperation of direction arch and guide way 33, can restrict the moving direction of spring bolt 3, avoid the spring bolt 3 skew.

As shown in fig. 2 and 4, the moving plate 4 has a meshing portion 43 at one end thereof located outside the tongue seat 8, the lock body 100 further includes a gear 9, the power portion 2 is a motor, and the gear 9 is connected to a rotating shaft of the motor and meshed with the meshing portion 43. Specifically, during unlocking, the motor is switched on, so that the motor drives the gear 8 to rotate, and the moving plate 4 is driven to move, and the moving plate 4 moves, so that the limiting part 4 moves along the first groove section 411, and the bolt 3 is driven to retract.

As shown in fig. 4, a guide groove 44 for guiding the moving plate 4 is formed at one end of the moving plate 4 outside the tongue base 8, and a guide member is disposed on the base 1 and penetrates the guide groove 44 to prevent the moving plate 4 from shifting during moving.

The invention also provides an intelligent lockset, which comprises the lock body 100. Specifically, the intelligent lockset can comprise a password input module, a fingerprint input module or a face recognition module, and the intelligent lockset can be set according to requirements.
