[0033] The following will describe in detail the specific embodiments of the present invention with reference to the drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0034] Unless otherwise clearly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0035] As Figures 1 to 4As shown in the figure, an embodiment of the present invention provides an automatically locking lock, which is composed of an automatically locking lock body 10 and a matching locking member 20. The automatically locking lock body 10 includes a lock shell 100, a lock tongue assembly 200, a locking assembly 300, and an unlocking assembly 400. The lock tongue assembly 200 is arranged in the lock shell 100 and can axially move relative to the lock shell 100 to partially protrude from the lock shell 100 and be locked in the locking member 20. The locking assembly 300 is arranged in the lock shell 100 and acts on the lock tongue assembly 200 to realize the automatic locking of the lock tongue assembly 200. The unlocking assembly 400 is arranged on the lock shell 100 and acts on the lock tongue assembly 200 to drive the lock tongue assembly 200 to move upward for unlocking operation.

[0036] The lock shell 100 is generally arranged in a cylindrical structure, and in other embodiments, it can also be arranged in the shape of a cuboid, etc. The present application does not limit this. A tongue cavity 101 is formed in the lock shell 100. A transmission sleeve 102 is arranged in the tongue cavity 101 in the lower half of the lock shell 100, and the transmission sleeve 102 is fixedly arranged with the lock shell 100. The transmission sleeve 102 is axially penetrated for the lock tongue assembly 200 to pass through.

[0037] As Figure 3 shown, a third keyway 1021 and a fourth keyway 1022 are formed on the transmission sleeve 102. The third keyway 1021 has a certain length in the axial direction of the transmission sleeve 102 and is used to cooperate with some components on the lock tongue assembly 200 to limit the axial movement distance of the lock tongue assembly 200. The fourth keyway 1022 is used to accommodate some components in the locking assembly 300.

[0038] In other embodiments, the transmission sleeve 102 can be integrally formed with the lock shell 100, or the transmission sleeve 102 can be not provided, and the thickness of the lock shell 100 can be appropriately increased, and the third keyway 1021 and the fourth keyway 1022 are directly formed on the lock shell 100.

[0039] As Figure 2 and Figure 3As shown, the bolt assembly 200 is disposed within the tongue cavity 101 (threaded through the transmission sleeve 102) and is slidable relative to the tongue cavity 101. The bolt assembly 200 includes a bolt body 201, a trigger rod 202, and a first elastic member 203. The bottom end of the trigger rod 202 is embedded within the bolt body 201, and a displacement space with a certain distance in the axial direction is formed between it and the bolt body 201. Specifically, an accommodation cavity 2011 is formed in the upper portion of the bolt body 201. The bottom end of the trigger rod 202 is embedded within the accommodation cavity 2011 of the bolt body 201 and slides up and down within the accommodation cavity 2011. The first elastic member 203 is disposed between the bolt body 201 and the lock housing 100 to provide a downward pressure to the bolt body 201. Specifically, the first elastic member 203 can be a spring. One end of the spring abuts against the upper end of the inner wall of the transmission sleeve 102, and the other end abuts against the upper end surface of the bolt body 201.

[0040] As Figure 3 and Figure 8 shown, a first keyway 2012 communicating with the internal accommodation cavity 2011 is formed on the bolt body 201. The first keyway 2012 is used for the partial components within the locking assembly 300 to pass through and be received. A third limiting member 2013 also protrudes from the surface of the bolt body 201. The third limiting member 2013 is correspondingly arranged with the third keyway 1021 on the transmission sleeve 102. And a part of the third limiting member 2013 extends into the third keyway 1021 and moves within the third keyway 1021 as the bolt body 201 moves. In a specific embodiment, the third limiting member 2013 can be a screw. After being threadedly connected with the bolt body 201, a part of it extends into the third keyway 1021. Axially symmetrically arranged slot holes 2014 are formed at the upper end of the bolt body 201. The slot holes 2014 have a certain length in the axial direction of the bolt body 201. When relative displacement occurs between the bolt body 201 and the trigger rod 202, the components of the trigger rod 202 extending into the slot holes 2014 can move in the length direction of the slot holes 2014 as the trigger rod 202 moves within the bolt body 201.

[0041] As Figure 3 and Figure 9 shown, a second keyway 2021 corresponding to the first keyway 2012 is radially formed through the bottom end of the trigger rod 202. The second keyway 2021 is also used to accommodate or receive some components within the locking assembly 300. Among them, the first keyway 2012, the second keyway 2021, and the fourth keyway 1022 are all coaxially arranged. A rack structure 2022 is formed at the top end of the trigger rod 202. The rack structure 2022 can cooperate with the unlocking assembly 400 to realize the upward movement and unlocking of the bolt assembly 200.

[0042] As Figure 3As shown in the figure, the locking assembly 300 includes a first limiting member 301, a second limiting member 302, a rotating member 303, and a second elastic member 304. The first limiting member 301 is disposed in the fourth keyway 1022 of the transmission sleeve 102 and is located at the lower end of the fourth keyway 1022. The first limiting member 301 is a horizontally arranged hanging post. The rotating member 303 is horizontally fixed in the second keyway 2021, and both ends of the rotating member 303 pass through the two side walls of the second keyway 2021, extend from the surface of the trigger rod 202 into the slot hole 2014, and can move in the length direction of the slot hole 2014 as the trigger rod 202 moves in the lock tongue body 201. The second limiting member 302 is disposed in the second keyway 2021 of the trigger rod 202. The second limiting member 302 can be a hook, one end of which is rotatably disposed on the rotating member 303, and the other end is hung on the first limiting member 301 (hanging post). At this time, the second limiting member 302 is in an inclined state, and one side thereof abuts against the bottom wall of the first keyway 2012. The second elastic member 304 is disposed in the first keyway 2012 of the lock tongue body 201 and acts on the second limiting member 302 to provide a holding force for the second limiting member 302 to approach the first limiting member 301 for locking. The second elastic member 304 can be a U-shaped spring.

[0043] Among them, when the automatic locking lock body 10 is in the unlocked state (as shown in Figure 3 and Figure 5 ), the second limiting member 302 passes through the first keyway 2012 and is locked with the first limiting member 301, so that the lock tongue assembly 200 remains relatively stationary with respect to the lock case 100, and the lock tongue assembly 200 will not move downward. At this time, the rotating member 303 is in a relatively upper position in the slot hole 2014. When the automatic locking lock body 10 triggers the locking operation, the lock tongue body 201 moves upward relative to the trigger rod 202 under the action of force. The second limiting member 302 is unlocked from the first limiting member 301 (detached from the first limiting member 301) under the abutment of the slot wall of the first keyway 2012. At the same time, because the rotating member 303 and the trigger rod 202 are integrally fixed, when the trigger rod 202 moves downward relative to the lock tongue body 201, the rotating member 303 moves downward in the slot hole 2014 on the lock tongue body 201, so that the second limiting member 302 is received in the first keyway 2012 and the second keyway 2021 under the abutment of the slot wall of the first keyway 2012. At this time, the lock tongue body 201 moves downward under the action of the first elastic member 203 and its own gravity, and drives the trigger rod 202 to move downward to perform locking.

[0044] Such as Figure 2 、 Figure 4 and Figure 6 and Figure 7 As shown in the figure, the unlocking assembly 400 includes a knob 401, a limiting seat 402, a trigger member 403, a third elastic member 404, and a gear set 405.

[0045] The gear set 405 includes an internal gear disk 4051, a driving disk 4052, planetary gears 4053, an input gear 4054, and an output gear 4055. The internal gear disk 4051 is fixed to the lock housing 100. The planetary gears 4053 and the input gear 4054 are both disposed within the internal gear disk 4051, and the input gear 4054 is coaxially disposed with the internal gear disk 4051. The planetary gears 4053 are internally engaged with the internal gear disk 4051 and externally engaged with the input gear 4054. The driving disk 4052 is fixedly connected to the planetary gears 4053 and rotatably connected to the input gear 4054. The output gear 4055 is synchronously rotationally connected to the input gear 4054 through a rotating shaft 4056, and the output gear 4055 is engaged with the rack structure 2022. A first limiting portion 40521 protrudes from the outer surface of the driving disk 4052. The first limiting portion 40521 can be an annular protrusion formed by splicing two semi-circular structures. The splicing portion of the two semi-circular structures is not connected, forming a limiting groove that can partially accommodate the trigger member 403.

[0046] The limiting seat 402 is fixed to the internal gear disk 4051 and covers the driving disk 4052. A through hole for accommodating the trigger member 403 is formed in the limiting seat 402. The trigger member 403 slidably passes through the through hole. One end of the trigger member 403 is fixedly connected to the knob 401, and a second limiting portion 4031 is formed at the other end, which is matched with the first limiting portion 40521 of the driving disk 4052. The second limiting portion 4031 can be a limiting protrusion adapted to the limiting groove. The limiting protrusion is clamped in the limiting groove, and the driving disk 4052 can be driven to rotate synchronously. A third elastic member 404 is disposed between the knob 401 and the limiting seat 402 to provide a force for the second limiting portion 4031 of the trigger member 403 to disengage from the first limiting portion 40521 of the driving disk 4052. The third elastic member 404 can be a conical spring.

[0047] Press the knob 401 to compress the third elastic member 404 and drive the trigger member 403 to engage with the driving disk 4052. Rotate the knob 401 to drive the driving disk 4052 to rotate. The rotation of the driving disk 4052 drives the planetary gears 4053 to rotate. The rotation of the planetary gears 4053 drives the intermediate input gear 4054 to rotate. Through the rotating shaft 4056, the rotation of the output gear 4055 is synchronously realized. The rotation of the output gear 4055 drives the trigger rod 202 to move upward for unlocking operation.

[0048] In this embodiment, by setting the gear set 405, the knob 401 can be rotated by a small angle to cause the lock tongue assembly 200 to rise significantly, achieving the unlocking operation. Specifically, the speed ratio is related to the sizes of the various gears set. At the same time, the trigger 403 is operably connected to the drive disk 4052 through the third elastic member 404 ("operably connected" means that two (or more) components are connected and cooperate with each other during the working process). This enables the knob 401 to directly act on the lock tongue assembly 200 during unlocking, facilitating unlocking; during locking, the knob 401 has no impact on the automatic locking of the lock tongue assembly 200.

[0049] As Figure 10 shown, the locking member 20 has a surface 21, on which a protrusion 22 is provided. The locking member 20 is provided with a lock hole 23 extending downward from the upper end of the protrusion 22. Due to the presence of the protrusion 22, the entrance end of the lock hole 23 is higher than the surface 21 of the locking member, and the side surface of the protrusion 22 is an inclined surface. When the lock tongue body 201 moves from the surface 21 towards the lock hole 23 and passes through this inclined surface, it is lifted by the protrusion 22, triggering the automatic locking operation, causing the first limiting member 301 and the second limiting member 302 to be unhooked and unlocked.

[0050] Since the unlocking of this automatically locking lock body 10 is achieved by manually rotating the knob 401, to improve the convenience of unlocking, a fourth elastic member 24 and a holding seat 25 are further provided in the lock hole 23. The upper end of the fourth elastic member 24 is connected to the holding seat 25, and the holding seat 25 can move within the lock hole 23. The elastic force of the fourth elastic member 24 is relatively small. While providing a certain resilience, it can avoid affecting the automatic locking of the lock tongue body 201.

[0051] Compared with the prior art, the automatically locking lock body of the embodiment of the present invention can simply and conveniently achieve the automatic locking of the lock body through the mechanical cooperation between components.

[0052] The automatically locking lock body of the embodiment of the present invention changes the speed ratio between the knob and the output gear by setting a gear set, achieving the quick unlocking of the automatically locking lock body.

[0053] For the automatically locking lock body of the embodiment of the present invention, during unlocking, the knob can be pressed to compress the third elastic member and drive the trigger to engage with the drive disk, and the knob is rotated to drive the drive disk to rotate, driving the output gear to rotate and engaging the gear structure of the trigger rod to perform the unlocking operation. After unlocking, the second limiting member locks with the first limiting member to maintain the raised state of the lock tongue body. During locking, the lock tongue body moves upward relative to the trigger rod under the action of force, causing the first limiting member and the second limiting member to be unlocked. The lock tongue body moves downward under its own gravity and the elastic force of the first elastic member to perform locking.

[0054] For the automatic locking lock body according to the embodiments of the present invention, during the locking process, the locking path and locking distance of the lock tongue body can be limited through the third keyway on the lock shell and the third limiting member on the lock tongue body.

[0055] The foregoing description of specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many changes and variations are possible in light of the above teaching. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical applications, so that those skilled in the art can implement and utilize the various different exemplary embodiments of the present invention, as well as various different selections and changes. The scope of the present invention is intended to be defined by the claims and their equivalents.
