Furthermore, the latch elastic element and the latch elastic reset element are respectively provided on both sides of the latch slider.

[0008] The starting assembly of this utility model includes a starting member and a starting elastic component. The starting member is rotatably disposed in the inner cavity of the lock housing assembly. One end of the starting member is connected to the starting elastic component and engages with the anti-locking component. The starting member is in close contact with the anti-locking component through the elastic force of the starting elastic component. The starting elastic component constitutes the reset mechanism of the starting member. The other end of the starting member is disposed near the inclined tongue sliding member, especially near the part of the inclined tongue sliding member parallel to the inclined tongue connecting member.

[0009] The deadbolt assembly of this utility model includes a square latch, a square latch connector, a square latch actuating assembly, and a square latch elastic assembly. The square latch is connected to the square latch connector, which is disposed in the inner cavity of the lock housing assembly.

The square latch connector has a sliding groove, and one end of the square latch actuating assembly reciprocates within the sliding groove of the square latch connector. The other end of the square latch actuating assembly is connected to the square latch elastic assembly, which constitutes the reset mechanism of the square latch actuating assembly.

[0010] The oblique tongue slider of this utility model has an L-shaped structure. The oblique tongue slider is provided with an oblique tongue sliding through hole, which is connected to the groove of the oblique tongue connector. The oblique tongue sliding through hole of the oblique tongue slider is smaller than the groove of the oblique tongue connector, so that the oblique tongue slider can move on the oblique tongue connector. An oblique tongue elastic reset member is provided at the upper end of the oblique tongue sliding through hole.

[0011] The diameter of the sliding through hole of the oblique tongue in this invention is smaller than the diameter of the oblique tongue connector, and the diameter of the sliding through hole of the oblique tongue is larger than the diameter of the groove of the oblique tongue connector, so that the oblique tongue slider is movable and fixed on the oblique tongue connector and will not detach from the oblique tongue connector.

[0012] When the latch retracts into the lock housing assembly, the latch connector moves backward. Since the latch elastic reset member and the latch connector are not on the same horizontal line, the latch elastic reset member applies a reverse force to the latch slider, causing the latch slider to tilt.

[0013] The square tongue actuating component of this utility model is rotatably disposed in the inner cavity of the lock housing component. The square tongue connector is provided with a sliding groove. One end of the square tongue actuating component is provided with a square tongue actuating slider. The square tongue actuating slider reciprocates within the sliding groove of the square tongue connector. The other end of the square tongue actuating component is connected to a square tongue elastic component.

[0014] In the automatic locking process of this utility model, under natural conditions, the latch retracts into the lock housing assembly under external force. The latch slider moves backward with the latch connector, and simultaneously, under the elastic force of the latch elastic reset component, the latch slider begins to gradually tilt. After the latch slider contacts and passes the actuator, the end face of the latch slider gradually moves to the same horizontal line as the actuator. Subsequently, without external force, the latch extends out of the lock housing assembly under the action of the latch elastic component, returning to its natural state. The latch slider moves forward with the latch connector, and simultaneously, the latch slider experiences less elastic force from the latch elastic reset component, causing the latch slider to gradually return to its normal position. The latch slider contacts and actuates the actuator. The actuator, actuated by the latch slider, disengages from the latch connector at its other end. Under the action of the latch actuation component and the elastic force of the latch elastic component, the latch connector extends out of the lock housing assembly, achieving automatic locking.

[0015] The lock housing assembly of this utility model includes a first lock housing component, a second lock housing component, and a third lock housing component. The first lock housing component and the second lock housing component are connected together. The third lock housing component is vertically connected and disposed on one side of the first lock housing component and the second lock housing component. The first lock housing component, the second lock housing component, and the third lock housing component are combined and connected to form a whole.

[0016] The oblique tongue slider of this utility model has an outwardly inclined curved part at one end, which increases the range of motion of the end of the oblique tongue slider around the oblique tongue connector.

[0017] The starting component of this utility model has an L-shaped structure, and the locking housing assembly is movably connected in the middle of the starting component, so that the starting component can rotate within the inner cavity of the locking housing assembly.

[0018] The automatic lock body of this utility model also includes a toggle assembly. The toggle assembly is rotatably disposed in the inner cavity of the lock housing assembly. The toggle assembly includes a toggle member and a square rod member. One end of the square rod member is connected to the toggle member, and the other end of the square rod member is connected to the door handle. When the door handle is rotated, the square rod member rotates simultaneously, and the movement of the square rod member drives the toggle member to rotate. The toggle member is positioned close to the latch slide member. When the toggle member rotates, the end of the toggle member contacts the latch slide member and the latch elastic reset member on the same horizontal line, causing the latch slide member to move backward. The latch slide member is simultaneously subjected to the elastic force of the latch elastic reset member and the latch elastic member. The latch slide member will not tilt or move backward, and the latch slide member will not contact the actuating member. The latch connector moves backward with the movement of the latch slide member, only causing the square tongue to retract into the lock housing assembly.

[0019] The mechanical automatic lock body of this utility model also includes a push assembly, which includes a push connector and a pusher. The pusher is rotatably disposed in the inner cavity of the lock housing assembly. One end of the push connector is connected to a toggle member, and the other end is connected to the pusher. The pusher contacts the square tongue toggle assembly.

[0020] In the locking and repositioning process of this utility model, in the locked state, the square tongue connector is subjected to the action of the square tongue actuating component and the elastic action of the square tongue elastic component, causing the square tongue to extend outside the lock housing assembly. When the user turns the door handle, the actuating component rotates, causing the oblique tongue sliding component to move backward. The oblique tongue connector moves backward with the oblique tongue sliding component, only causing the square tongue to retract into the lock housing assembly. On the other hand, by pushing the connector, the pushing component rotates, causing the square tongue actuating component to move, overcoming the elastic action of the square tongue elastic component. The square tongue connector moves backward, and the square tongue retracts into the lock housing assembly. After the square tongue connector moves backward a certain distance, the actuating component locks the square tongue connector, the deadbolt assembly is in a stable state, and the entire lock body returns to the unlocked state.

[0021] The mechanical automatic lock body of this utility model also includes a lock cylinder assembly. The lock cylinder assembly is inserted into the lock housing assembly and disposed on one side of the push connector. The lock cylinder assembly includes a lock cylinder component and a fork component. The fork component is rotatably disposed in the inner cavity of the lock cylinder component. When the fork component rotates, it can contact the push connector and drive the push connector to move.

[0022] In the locking and repositioning process of this utility model, when locked, the square tongue connector is subjected to the action of the square tongue actuating component and the elastic action of the square tongue elastic component, causing the square tongue to extend outside the lock housing component. When the user turns the key, the key rotation drives the fork to rotate, which in turn drives the push connector to move. The push connector then drives the push component to rotate, which in turn drives the square tongue actuating component to move, overcoming the elastic action of the square tongue elastic component. The square tongue connector moves backward, and the square tongue retracts into the lock housing component. After the square tongue connector moves backward a certain distance, the actuating component locks the square tongue connector, the deadbolt component is in a stable state, and the entire lock body returns to the unlocked state.

[0023] The beneficial effects of this utility model are: when the door is closed, it automatically locks, solving the trouble of users forgetting to lock it, and also greatly saving the time of lifting the handle to lock or using a key to lock it when closing the door. In addition, the mechanical locking is used throughout the process, ensuring long-term use without the need to replace batteries, reducing the cost of using the door and reducing the cost of manufacturing the door. It has high safety performance and strong practicality. Attached Figure Description
