Description

Technical Field

[0001] This invention relates to a lock body structure with a reversible deadbolt. Background Technology

[0002] See Figure 11 In existing smart spherical locks, when the lock is deadbolted, the deadbolt lever 50 is manually twisted. When the deadbolt lever 50 rotates, it drives the bracket 510 located in the front lock body to rotate. The bracket 510 is equipped with a sensing element. When the sensing element rotates to the deadbolt position, it senses the sensor on the circuit board 520. The circuit board 520 then controls the motor to drive the deadbolt mechanism to deadbolt the lock.

[0003] Based on the above, the existing technical problem is that the current spherical lock does not have a structure for automatically resetting the deadbolt 50. When the user turns the lock body to open the door without manually resetting the deadbolt, the deadbolt remains at the deadbolt angle, causing the sensing element on the bracket 510 to remain in the sensing position. When the user leaves and closes the door, because the sensing element remains in the sensing position, the circuit board 520 controls the motor to drive the deadbolt mechanism to lock again. In the deadbolt state, the user is outdoors and cannot directly open the door using fingerprint recognition; they must log in to the administrator mode to unlock the door, which is complex and has drawbacks, requiring further improvement. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a lock body structure with a resettable deadbolt.

[0005] A lock body structure with resetting deadbolt designed for this purpose includes a front lock body and a rear lock body. A rotating assembly is rotatably disposed on the front lock body, and a deadbolt rotating component that can rotate relative to the rotating assembly is disposed inside the rotating assembly. The anti-lock rotating component is connected to an anti-lock rod, the rotating assembly is connected to a square rod, and the other end of the square rod is connected to the rear lock body; The anti-locking rotating member is provided with a driven part, and the rotating assembly is provided with a driving part that can fit with the driven part. When the rotating assembly rotates in the first direction, the driving part drives the driven part to drive the anti-locking rotating member to rotate synchronously with the rotating assembly. The anti-locking rotating component is provided with a pin hole, and the rotating assembly is provided with a locking pin assembly that can be inserted into the pin hole. When the rotating assembly rotates to the anti-locking position in the second direction, the locking pin assembly can be inserted into the pin hole.

[0006] Preferably, the rotating assembly is provided with a mounting hole that can communicate with the pin hole. The locking pin assembly includes a connecting pin that is movably disposed in the mounting hole. A spring is connected to the mounting hole and the connecting pin. The spring applies a force to the connecting pin away from the pin hole. A driving member is provided on the front lock body for driving the connecting pin to be inserted into the pin hole.

[0007] Preferably, the driving element is a first magnet disposed on the front lock body, and a second magnet is disposed at one end of the connecting pin facing the front lock body, wherein the second magnet and the driving element are like poles that repel each other.

[0008] Preferably, the rotating assembly consists of a first rotating member and a second rotating member, with a mounting cavity formed between the first rotating member and the second rotating member, and the anti-locking rotating member is rotatably disposed within the mounting cavity; The first rotating member is provided with a driven tooth groove, and the second rotating member is provided with a drive tooth for insertion into the driven tooth groove.

[0009] Preferably, the square rod is connected to the second rotating member.

[0010] Compared with existing technologies, this invention, when the user rotates the rear lock body, causing the square rod to drive the rotating assembly to rotate in the first direction, the driving part drives the driven part to drive the anti-lock rotating member to rotate synchronously with the rotating assembly, thereby driving the anti-lock rod to reset. When the user rotates the rear lock body, causing the square rod to drive the rotating assembly to rotate in the second direction, the locking pin assembly moves to the anti-lock position under the drive of the rotating assembly. The locking pin assembly inserts into the pin hole. When the locking pin assembly is inserted into the pin hole, the rear lock body has already driven the bolt to complete the unlocking step. When the user releases the rear lock body, the rear lock body resets under the action of the torsion spring. During the reset process, the rotating assembly rotates in the first direction, driving the anti-lock rotating member to rotate synchronously with the rotating assembly, thereby driving the anti-lock rod to reset. This invention can drive the anti-lock rod to reset whenever the user rotates the rear lock body in either the first or second direction, so that the anti-lock can be automatically released in both left-opening and right-opening doors, avoiding the problem of forgetting to manually reset and causing the lock body to re-lock, locking the user outdoors, and avoiding the problem of accidental anti-locking.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] See Figures 1-10 A lock body structure with a resetting deadbolt includes a front lock body 10 and a rear lock body 70. A rotating assembly 100 is rotatably disposed on the front lock body 10, and a deadbolt rotating member 60 that can rotate relative to the rotating assembly 100 is disposed inside the rotating assembly 100. The anti-locking rotating component 60 is connected to the anti-locking rod 50, the rotating assembly 100 is connected to the square rod 40, the other end of the square rod 40 is connected to the rear lock body 70, and an anti-locking knob 80 is rotatably provided on the rear lock body 70, which is connected to the anti-locking rod 50. The anti-locking rotating member 60 is provided with a driven part 620, and the rotating assembly 100 is provided with a driving part 320 that can fit with the driven part 620. When the rotating assembly 100 rotates in the first direction, the driving part 320 drives the driven part 620 to drive the anti-locking rotating member 60 to rotate synchronously with the rotating assembly 100. The anti-locking rotating component 60 is provided with a pin hole 610, and the rotating assembly 100 is provided with a locking pin assembly 200 that can be inserted into the pin hole 610. When the rotating assembly 100 rotates to the anti-locking position in the second direction, the locking pin assembly 200 can be inserted into the pin hole 610.

[0014] When the user rotates the rear lock body in the first direction, it drives the square rod to rotate the rotating assembly in the first direction. The driving part drives the driven part to drive the anti-lock rotating member to rotate synchronously with the rotating assembly (e.g., Figure 6 As shown in the figure, this causes the anti-lock lever to reset.

[0015] When the user rotates the lock body in the second direction, it drives the square rod to rotate the rotating assembly in the second direction. When the locking pin assembly moves to the deadbolt position under the drive of the rotating assembly (e.g., ...), Figure 8 As shown), the locking pin assembly is inserted into the pin hole. When the locking pin assembly is inserted into the pin hole, the rear lock body has already driven the lock tongue to complete the unlocking step. When the user releases the rear lock body, the rear lock body resets under the action of the torsion spring. During the reset process, the rotating assembly rotates along the first direction to drive the anti-lock rotating part to rotate synchronously with the rotating assembly, thereby driving the anti-lock rod to reset.

[0016] The first direction of rotation is counterclockwise, and the second direction is clockwise. This setting is to match different door opening directions. When switching between left-hand and right-hand door opening, the direction of the lock body after turning is different, so that the deadbolt can be reset in both different door opening directions.

[0017] See Figure 2 , Figure 3 and Figure 5 The rotating assembly 100 is provided with a mounting hole 220, which can communicate with the pin hole 610. The locking pin assembly 200 includes a connecting pin 230 movably disposed in the mounting hole 220. A spring 240 is connected to the mounting hole 220 and the connecting pin 230. The spring 240 applies a force to the connecting pin 230 away from the pin hole 610. A driving member 110 is provided on the front lock body 10 for driving the connecting pin 230 to be inserted into the pin hole 610.

[0018] See Figure 6 When the anti-locking lever 50 is in the anti-locked state, the pin hole 610 corresponds to the driving member 110, and this position is the anti-locked position. When the locking pin assembly moves to the anti-locked position under the drive of the rotating component, the locking pin assembly is inserted into the pin hole under the drive of the driving member 110.

[0019] Under the force of spring 240, connecting pin 230 remains within mounting hole 220. When connecting pin 230 corresponds to driving member 110, driving member 110 drives connecting pin 230 to insert into pin hole 610. When connecting pin 230 is inserted into pin hole 610, rotating assembly 100 and anti-locking rotating member 60 rotate synchronously. Rear lock body 70 rotates to reset in the first direction under the action of torsion spring, thereby driving square rod 40 to drive rotating assembly to drive anti-locking rotating member to rotate synchronously, thereby driving anti-locking rod to reset.

[0020] In this invention, the driving component 110 is a first magnet disposed on the front lock body 10, and a second magnet 250 is disposed at one end of the connecting pin 230 facing the front lock body 10. The second magnet 250 and the driving component 110 are like poles that repel each other.

[0021] When the locking pin assembly 200 rotates to the anti-lock position with the rotating assembly 100, the connecting pin 230 is inserted into the pin hole 610 under the action of magnetic repulsion. When the rotating assembly 100 returns to its original position in the first direction after the rear lock body 70, the locking pin assembly 200 and the first magnet are misaligned, the mutual repulsion between the first magnet and the second magnet 250 is eliminated, and the locking pin assembly 200 is withdrawn from the pin hole 610 under the action of the spring 240.

[0022] See Figure 1 and Figure 2 The rotating assembly 100 is composed of a first rotating member 20 and a second rotating member 30, and a mounting cavity is formed between the first rotating member 20 and the second rotating member 30. The anti-locking rotating member 60 is rotatably disposed in the mounting cavity. The first rotating member 20 is provided with a driven tooth groove 210, and the second rotating member 30 is provided with a drive tooth 310 for inserting into the driven tooth groove 210.

[0023] See Figure 1 and Figure 2 The square rod 40 is connected to the second rotating member 30. When the rear lock body 70 rotates, it drives the square rod 40 to rotate, which in turn drives the second rotating member 30 to rotate. The second rotating member 30 drives the first rotating member 20 to rotate via the drive gear 310.
