Referring to fig. 1 to 2, the lock body capable of automatically locking in the embodiment of the utility model comprises a lock body shell 1, a bolt 2, a shifting fork 3 and a boosting torsion spring 4. The lock body shell 1 is used as a structural frame of the lock body capable of being automatically locked and has a protection effect on internal parts, and a part of the shell of the lock body shell 1 is hidden in the attached drawings so as to show the technical key point of the utility model. The bolt 2 is connected in the lock body shell 1 in a sliding mode, one end of the bolt can be exposed out of the lock body shell 1 and is abutted to a lock hole matched with the bolt, and the door locking effect is achieved. The fork 3 is rotatably connected in the lock body housing 1 and is provided with a push-pull strip 31 and a pressure strip 32. The push-pull strip 31 and the pressure strip 32 are both integrated convex structures on the shifting fork 3.

The push-pull strip 31 is used for driving the bolt 2 to slide. Specifically, the locking bolt 2 includes a tongue 21 and a locking bolt push plate 22, and the tongue 21 is connected with the locking bolt push plate 22. Wherein, the bolt pushing plate 22 is provided with a guiding sliding groove 221 and a driving groove 222. The guide sliding groove 221 is adapted to the guide pin 11 on the lock body housing 1, so that the latch bolt 2 can slide along the direction of the guide sliding groove 221. The push-pull strip 31 on the shifting fork 3 is provided with a convex block, when the shifting fork 3 rotates, the convex block on the push-pull strip 31 slides in the driving groove 222 and drives the lock tongue 2 to move, so that the control of the lock tongue is realized.

Two ends of the boosting torsion spring 4 are respectively hinged to the compression strip 32 and the lock body shell 1. Referring to fig. 2, at this time, the bolt 2 is completely exposed, the boosting torsion spring 4 is located at the extreme of the stroke thereof, and the posture of the boosting torsion spring 4 at this time is set as a first posture; referring to fig. 4, at this time, the latch 2 is completely retracted, the boosting torsion spring 4 is located at the other extreme of the stroke, and the posture of the boosting torsion spring 4 is set to be the second posture. The booster torsion spring 4 is always in a compressed state. In the process of changing the boosting torsion spring 4 from the first posture to the second posture, referring to fig. 3, the boosting torsion spring 4 is firstly compressed and then released, and the elastic potential energy thereof is firstly increased and then reduced. By adopting the design, the boosting torsion spring 4 can perform certain boosting in the rear half section of unlocking or the rear half section of locking, so that the hand feeling of the locking and unlocking is improved; and the boosting torsion spring 4 can force the bolt 2 to be positioned at an unlocking or locking position, and the bolt 2 can not change state even if the handle is loosened, so that the self-locking mechanism has a self-locking function.

In order to realize linkage control connection of the handle and the first shifting fork 3, further, the lock body capable of being automatically locked further comprises a linkage device 5, the linkage device 5 is provided with a square hole 51, the square hole 51 is used for being connected with the handle, the linkage device 5 is connected with the shifting fork 3, and therefore the handle can drive the shifting fork 3 through the linkage device 5 to realize locking and unlocking.

In order to rotate the handle and enable the handle to return automatically, furthermore, the lock body capable of automatically locking also comprises a reset torsion spring 6, and two ends of the reset torsion spring 6 are respectively connected to the linkage device 5 and the lock body shell 1, so that the linkage device 5 is driven to reset, and the handle is driven to reset along with the linkage device.

Further, the linkage device 5 is further provided with at least two side baffles 52, the side baffles 52 enclose an accommodating space, the reset torsion spring 6 is annular and is accommodated in the accommodating space, specifically, after the reset torsion spring 6 stores elastic potential energy, two extending feet (namely two ends) of the reset torsion spring are clamped at two sides of the two side baffles 52 and the fixing bulges inside the lock shell 1, after the reset torsion spring is installed, when the handle is in a natural horizontal state, the two side baffles 52 are overlapped with the fixing bulges inside the lock shell 1; after the external force driving the linkage device 5 to rotate is removed, the reset torsion spring 6 releases elastic potential energy, the extending foot which rotates pushes against and drives one of the side baffles 52 to drive the linkage device 5 to reset, the linkage device 5 is synchronously and rotatably connected with the handle, and therefore the linkage device 5 drives the handle to reset.

Further, the linkage device 5 can rotate relative to the shifting fork 3, the linkage device 5 is further provided with a linkage block 53, the shifting fork 3 is further provided with an avoiding empty groove 33, and the linkage block 53 is arranged in the avoiding empty groove 33. When a user unlocks the lock through the handle, the handle is pressed down, the linkage 5 is driven by the handle to rotate clockwise, the driving block 53 is contacted with one side of the avoidance empty groove 33 and drives the shifting fork 3 to rotate clockwise, and the bolt 2 retracts through the push-pull strip 31. When the external force on the handle is removed, the reset torsion spring 6 drives the linkage 5 to rotate anticlockwise, and the handle is reset. However, the linkage block 53 moves in the avoidance empty groove 33, and does not drive the shifting fork 3 to rotate together, so that the shifting fork 3 is kept static, and the bolt 2 is kept in a state. Thereby realizing the technical effect that the handle resets and the bolt 2 does not reset.

When the lock needs to be closed, the handle is lifted, the linkage device 5 rotates anticlockwise, the linkage block 53 is in contact with the other side of the avoidance empty groove 33 and drives the shifting fork 3 to rotate anticlockwise, and the lock tongue 2 extends out through the push-pull strip. When the external force on the handle is removed, the linkage 5 is driven by the reset torsion spring 6 to reset, and the bolt 2 keeps the state under the action of the boosting torsion spring 4.

Furthermore, the lock body capable of automatically locking also comprises a lock body panel 7, wherein the lock body panel 7 is connected with the lock body shell 1, and is provided with a mounting hole 71 for connecting with a door body to play a role of fixing the lock body.

Further, the lock body panel 7 is provided with a guide hole 72, and the latch bolt 2 is exposed through the guide hole 72. Through setting up guiding hole 72, can not take place the skew when guaranteeing that spring bolt 2 stretches out, the smooth degree when improving spring bolt 2 and sliding.

Further, the lock body capable of automatically locking further comprises a silencing sleeve 8, wherein the silencing sleeve 8 is arranged at the position of the guide hole 72 and used for buffering the collision of the lock bolt 2 on the lock body panel 7, and meanwhile, the noise generated when the lock is opened and closed is also reduced.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the utility model as set forth in the claims appended hereto.
