Background
At present, a two-way sliding tongue device is usually adopted for the anti-theft door lock, and the two-way sliding tongue device is often fixed only by matching a trigger shifting piece with a trigger tongue when the door is closed, so that a key is still needed to be used for shifting the trigger shifting piece to drive the trigger tongue to retract when the door is opened after the door is opened, and the use is inconvenient.
Disclosure of Invention
In order to facilitate use, the invention provides a lock body which comprises a limiting frame, a tipping bucket tongue mechanism, a turnover part, a reset torsion spring and an unlocking poking part, wherein a left side plate and a right side plate of the limiting frame are clamped at two sides of a tipping bucket tongue notch on the side wall of the lock body;
the tipping bucket tongue mechanism comprises a tipping bucket tongue, a fixing piece and a return spring, wherein a limiting sliding groove is formed in the right side surface, facing the right side plate of the limiting frame, of the tipping bucket tongue, and the limiting sliding groove is opposite to the overturning clamping groove; the fixed part comprises a fixed seat and a sliding rod, a contact end of the fixed seat is in rotatable contact with an overturning end of the bucket tongue, and a free end of the sliding rod deviates from the contact end of the fixed seat and is inserted into the sliding through hole; the reset spring is sleeved on the sliding rod and clamped between the fixed seat and the limiting plate;
the turnover piece comprises a bottom block, a vertical plate and an upright post, wherein the vertical plate is fixedly connected with the bottom block at the connecting end of the bottom block, the upright post is positioned at the top of the bottom block and close to the reset end of the bottom block, and the reset end of the bottom block is provided with a reset clamping groove; a turnover transverse plate is arranged on the side surface of the vertical plate, which is far away from the upright post, and the turnover transverse plate can penetrate through the turnover clamping groove and be inserted into the limiting sliding groove;
the unlocking shifting piece comprises a shifting sleeve, a shifting piece and a shifting arm, wherein the shifting piece and the shifting arm are arranged on the shifting sleeve, and an accommodating shifting groove is formed between the shifting piece and the shifting arm; the shifting sleeve is sleeved on an unlocking upright post in the lock body, the shifting sheet is clamped between the vertical plate and the upright post, the upright post is inserted in the accommodating shifting groove, and the free end of the shifting arm extends to the driving device and can drive the shifting sleeve to rotate around the unlocking upright post under the driving of the driving device;
the reset torsion spring is sleeved on the shifting sleeve and pressed by the shifting piece and the shifting arm, one end of the reset torsion spring is pressed on the side wall of the lock body in a propping manner, and the other end of the reset torsion spring is inserted into the reset clamping groove on the overturning part.
In the process of opening the door, a door opener pulls the handle to enable the handle to drive a lock body driving gear in a driving device in the lock body to rotate, so that the lock body driving gear drives a shifting arm in an unlocking shifting piece to drive a shifting piece to rotate around an unlocking upright post so as to be away from the limiting frame, and the shifting piece can apply force to the upright post in the overturning piece to push the overturning piece to move in the direction away from the limiting frame when being away from the limiting frame, so that an overturning transverse plate in the overturning piece slides out of a limiting sliding groove in a tipping bucket tongue, at the moment, the door is pushed to enable the tipping bucket tongue to overturn under stress and slide out of a tipping bucket tongue accommodating groove in a door frame and retract into the limiting frame, and the door. In the door closing process, when a door closing person pulls the handle to enable the door plate to be buckled with the door frame, the tipping bucket tongue slides out of the limiting frame under the action of the reset spring and is inserted into the tipping bucket tongue accommodating groove on the door frame, at the moment, the door closing person loosens the handle, the lock body driving gear in the driving device reversely rotates and resets, the overturning piece moves towards the limiting frame under the action of the reset torsion spring until the overturning transverse plate on the overturning piece is inserted into the limiting sliding groove on the tipping bucket tongue, and the overturning transverse plate clamps the tipping bucket tongue to prevent the tipping bucket tongue from sliding out of the tipping bucket tongue accommodating groove. Therefore, the lock body is simple and convenient to open and close the door when the door is not locked.
Preferably, the side of the tipping tongue is provided with two parallel limiting sliding grooves, the right side plate of the limiting frame is provided with two turning clamping grooves, and the vertical plate of the turning piece is provided with two turning transverse plates. Therefore, the two overturning transverse plates are matched with the two limiting sliding grooves on the tipping bucket tongue to clamp the tipping bucket tongue, and the stability of the tipping bucket tongue when the tipping bucket tongue is clamped by the overturning part can be improved. Furthermore, the two sides of the tipping tongue are symmetrically provided with the limiting sliding grooves. Therefore, when the lock body is assembled, the installation direction of the tipping tongue does not need to be confirmed, the assembly efficiency can be improved, and the production cost of the lock body is reduced.
Preferably, in the turning piece, a top protrusion is arranged at the top of the vertical plate, and a bottom protrusion is arranged at the bottom of the vertical plate. Therefore, when the lock body is implemented specifically, the top lug can be inserted into the guide sliding groove on the top panel of the lock body, and the bottom lug can be inserted into the guide sliding groove on the bottom panel of the lock body, so that the turnover part moves along the guide sliding groove when being far away from or close to the limiting frame, and the influence on reset and even on use of the lock body due to dislocation of the turnover part in the moving process is avoided.
Preferably, the limiting frame is a U-shaped frame. The limiting frame is simple in structure and convenient to manufacture.
