Description

Technical Field

[0001] The present invention relates to the technical field of door lock cabinets, and in particular to a lock, an electrical connector, and a power supply or power consumption device. Background Art

[0002] For purposes such as anti-theft and restriction of usage permissions, many real-world scenarios use the locking and unlocking functions of lock mechanisms to control application scenarios. Due to structural and functional limitations and requirements, many scenarios require the design of unique, non-standard lock mechanisms. However, most existing lock mechanisms are cumbersome and unintelligent to unlock and unlock, complex in design, resulting in high costs and increased failure and damage rates due to multiple components, bulky in size and space, and difficult to achieve theoretical accuracy, leading to false locking or unlocking errors or loose locking.

[0003] Therefore, the lock mechanism has been continuously innovated and improved, especially the lock mechanism provided in the connector. Summary of the Invention

[0004] The present invention utilizes an ingenious mechanical linkage method to invent a very practical lock, an electrical connector that is compatible with the lock, and a power supply or power-consuming device. It can adapt to many application scenarios that require locks, and is easy to operate and functional.

[0005] A first aspect of the present invention provides a lock comprising: The circular lock cylinder has an inclined guide groove on its curved surface and a lock tongue protruding outward; the circular lock cylinder is also provided with a locking connection portion; A guide slide shaft is provided with a guide slide protrusion that fits into the guide groove; and the entire guide slide shaft is limited to being able to move back and forth only along the central axis of the circular lock cylinder under force without being separated from the circular lock cylinder; an elastic restoring member, which always applies an elastic force along one direction of the central axis to the guide slide shaft; a locking mechanism movably mounted near the locking tongue; Wherein, the circular lock cylinder is limited to being able to rotate only by itself under force; In the natural state, the guide slide shaft is moved in the opposite direction of the elastic force by the external force, and at the same time, the guide slide protrusion drives the circular lock cylinder to rotate adaptively along the guide groove, so that the locking connection part rotates to the locked state, and the lock tongue is driven to rotate to a range where the lock tongue can be automatically limited by the locking mechanism to rotate in the return direction; In the locked state, the locking mechanism is withdrawn from the lock tongue, and when the external force is withdrawn, the elastic force drives the guide shaft to return to the position in the natural state, and the entire round lock cylinder is driven to rotate reversely to the position in the natural state during the recovery process.

[0006] In some embodiments of the present invention, two monitoring switches are spaced apart within the rotation range of the lock tongue; One is used to monitor whether the lock tongue returns to the preset position in the natural state when in the natural state; and / or is used to monitor whether the locking mechanism successfully automatically limits the reverse rotation of the lock tongue in the locked state; The other is used to monitor whether the lock tongue is driven to rotate to the preset position in the locked state.

[0007] Furthermore, the locking mechanism includes a locking slider, an automatic rod, and a control rod portion; the automatic rod is respectively connected to the locking slider and the control rod portion; the automatic rod always automatically applies a thrust to the locking slider, and when there is no other force acting, the thrust is sufficient to drive the locking slider into the range where the reverse rotation of the lock tongue is limited; the control rod portion can adopt an electric control structure and / or a mechanical control structure; the control rod portion can be used to drive the automatic rod and the locking slider to withdraw from the range where the reverse rotation of the lock tongue is limited.

[0008] In some embodiments of the present invention, a positioning groove is provided on the locking slider; the locking mechanism further includes a positioning rod, the first end of which is fixed, and the second end is movable in and out of the positioning groove relative to the locking slider and along with the movement of the locking slider; in the locked state, when the control rod portion controls the locking slider to withdraw from the range where the reverse rotation of the lock tongue can be limited, the second end of the positioning rod enters into the positioning groove to position the locking slider and the automatic rod at this position; and at this time, if the external force applied to the guide shaft is withdrawn, the second end of the positioning rod can be separated from the positioning groove during the reverse rotation process of the lock tongue when it returns to the natural state.

[0009] Furthermore, two avoidance sliding grooves are respectively and communicatively provided at both ends of the positioning groove, and the two avoidance sliding grooves are respectively the two sliding strokes of the second end of the positioning rod before entering the positioning groove and after separating from the positioning groove.

[0010] Furthermore, the two avoidance sliding grooves and the positioning groove form a communicating annular groove, and the second end of the positioning rod is limited to slide in only one direction within the annular groove.

[0011] Further, at the junction of each slot section of the annular groove, there are formed high and low steps; at any junction of the slot sections, the slot section where the second end of the positioning rod is located is always the high-step surface of the high and low steps, and the next slot section into which the second end of the positioning rod is about to slide is the low-step surface of the high and low steps.

[0012] Further, the positioning groove is a V-shaped groove; the sliding stroke of the second end of the positioning rod before entering the positioning groove is a first avoidance sliding groove; the starting end of the first half slot section of the V-shaped groove is inclined towards the center line of the V-shaped groove, and this first half slot section is connected to the first avoidance sliding groove.

[0013] In a second aspect of the present invention, an electrical connector is disclosed, including: an energized connection part for realizing electrical connection between two objects; and a locking device, which adopts the locking device described in any one of the above, for realizing structural locking connection and unlocking of the two electrically connected objects.

[0014] In a third aspect of the present invention, a power supply or power-consuming device is disclosed, and the power supply or power-consuming device is equipped with the electrical connector described in the above paragraph; or the power supply or power-consuming device is equipped with the locking device described in any one of the above.

[0015] The technical solution provided by the embodiments of the present application may include the following beneficial effects: The present invention ingeniously designs the circular lock cylinder and the guide slide shaft into a combined structure that cooperates with each other. By using their linkage mode and configuring a locking mechanism capable of realizing the automatic locking function, the locking and unlocking are achieved. The guide slide protrusion provided on the guide slide shaft is adaptively inserted into the guide groove of the circular lock cylinder to ensure that the guide slide shaft cannot be separated from the circular lock cylinder (the guide slide protrusion is always within the guide groove), and the inclined guide groove becomes the sliding track of the guide slide protrusion on the curved surface of the circular lock cylinder. Additionally, the guide slide shaft is set to be only able to move back and forth along the central axis direction (linear reciprocating motion in this direction). Therefore, when the guide slide shaft is pushed by an external force, it will move along one direction of the central axis (the same as the direction of the external force and opposite to the direction of the elastic restoring force exerted on the guide slide shaft by the elastic restoring member). At the same time, since the circular lock cylinder is limited to only rotate itself (i.e., it cannot move along the central axis direction with the guide slide shaft), during the linear motion of the guide slide protrusion, it will conduct the external force received along and on the inner wall of the guide groove to drive the entire circular lock cylinder to rotate (the rotation angle is adapted to the linear movement distance of the guide slide protrusion); and the locking connection portion provided on the circular lock cylinder can be driven to rotate to the locked state; and the lock tongue is driven to rotate to a range where the locking mechanism can automatically limit the reverse rotation of the lock tongue. At this time, the locking mechanism installed near the lock tongue can automatically spring into the reverse rotation stroke of the lock tongue to form an obstacle to the reverse rotation of the lock tongue. Therefore, after an external object is adaptively docked with the locking connection portion, when the entire circular lock cylinder rotates to the locked state and the locking mechanism limits the reverse rotation of the lock tongue, the entire circular lock cylinder can be limited from rotating reversely, and the external object cannot be separated from the locking connection portion, thus achieving the locking of the external object and preventing it from being taken away.

[0016] Certainly, the lock of the present invention is also provided with an elastic restoring member that always exerts an elastic force on the guide slide shaft in the direction opposite to the external force (it can be understood that this elastic force gradually increases as the external force increases, that is, the greater the distance the guide slide shaft moves under the action of the external force, the stronger this elastic force). By using this elastic force acting on the guide slide shaft, when the locking mechanism withdraws from the lock tongue and the external force applied to the guide slide shaft is withdrawn, it can automatically drive the guide slide shaft to move reversely and return to the position before being subjected to the external force. Similar to the principle of locking by force rotation, during the reverse reset movement of the guide slide shaft, due to the movement of the guide slide protrusion in the guide groove, the guide slide shaft can simultaneously drive the entire circular lock cylinder to rotate reversely and return to the natural state position when not subjected to the external force. Thus, after unlocking, the external object can be taken away from the locking connection portion of the circular lock cylinder, and the linkage combination of the guide slide shaft and the circular lock cylinder can automatically reset to prepare for connecting and locking with the external object next time.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0021] Next, some embodiments of the present invention will be described in detail with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0022] A first aspect of the present application provides a lock, comprising: a circular lock cylinder 10, a guide slide shaft 20, an elastic restoring member 30, and a locking mechanism 40; on the curved surface of the circular lock cylinder 10, there are provided inclined guide grooves 13 and a locking tongue 14 protruding outward; the circular lock cylinder 10 is further provided with an upper locking connection portion 15; the guide slide shaft 20 is provided with a guide slide protrusion 21 that fits into the guide groove 13; and the entire guide slide shaft 20 is limited to only move back and forth along the direction of the central axis of the circular lock cylinder 10 (the central axis mentioned herein all refers to the central axis of the circular lock cylinder 10) under force and does not disengage from the circular lock cylinder 10; the elastic restoring member 30 always applies an elastic force to the guide slide shaft 20 along one of the directions of the central axis; the locking mechanism 40 is movably installed near the locking tongue 14; wherein, the circular lock cylinder 10 is limited to only rotate self-rotationally under force; in the natural state, the guide slide shaft 20 moves in the opposite direction of the elastic force (from the elastic restoring member 30) under an external force, and at the same time, the guide slide protrusion 21 drives the circular lock cylinder 10 to perform an adaptive self-rotation along the guide groove 13, so that the upper locking connection portion 15 rotates to the upper locking state, and the locking tongue 14 is driven to rotate to a range where the locking mechanism 40 can automatically limit the reverse rotation of the locking tongue 14; in the upper locking state, the locking mechanism 40 is withdrawn from the locking tongue 14, and when the external force applied to the guide slide shaft 20 is withdrawn, the elastic force applied by the elastic restoring member 30 to the guide slide shaft 20 drives the guide slide shaft 20 to return to the position in the above-mentioned natural state, and the recovery process drives the entire circular lock cylinder 10 to rotate reversely to the position in the natural state (that is, when the locking mechanism 40 is withdrawn from the locking tongue 14 and the external force is withdrawn, the elastic restoring member 30 automatically releases potential energy and transforms it into elastic force, acting on the connected guide slide shaft 20, driving the guide slide shaft 20 to move along the direction of the elastic force to return to the natural state where the guide slide shaft 20 is in force balance).

[0023] The present invention ingeniously designs the circular lock cylinder 10 and the guide shaft 20 into a combined structure that cooperates with each other. By using their linkage mode and a locking mechanism 40 configured to achieve an automatic locking function, locking and unlocking are realized. The guide protrusion 21 provided on the guide shaft 20 is adaptively inserted into the guide groove 13 of the circular lock cylinder 10 to ensure that the guide shaft 20 cannot disengage from the circular lock cylinder 10 (the guide protrusion 21 is always within the guide groove 13), and the inclined guide groove 13 becomes the sliding track of the guide protrusion 21 on the curved surface of the circular lock cylinder 10. Additionally, the guide shaft 20 is set to be able to move only back and forth along the central axis direction (linear reciprocating motion in this direction). Therefore, when the guide shaft 20 is pushed by an external force, it will move along one direction of the central axis (the same as the direction of the external force and opposite to the direction of the elastic restoring force exerted by the elastic restoring member 30 on the guide shaft 20). At the same time, since the circular lock cylinder 10 is limited to only rotate (i.e., it cannot move along the central axis direction with the guide shaft 20), during the linear movement of the guide protrusion 21, the external force received will be conducted along and on the inner wall of the guide groove 13 to drive the entire circular lock cylinder 10 to rotate (the rotation angle is adapted to the linear movement distance of the guide protrusion 21); the locking connection portion 15 provided on the circular lock cylinder 10 can be driven to rotate to the locked state; and the lock tongue 14 is driven to rotate to a range where the locking mechanism 40 can automatically limit the reverse rotation of the lock tongue 14. At this time, the locking mechanism 40 installed near the lock tongue 14 can automatically pop into the reverse rotation stroke of the lock tongue 14 to form an obstacle to the reverse rotation of the lock tongue 14. Therefore, after an external object is adaptively docked with the locking connection portion 15, the entire circular lock cylinder 10 rotates to the locked state and the locking mechanism 40 limits the reverse rotation of the lock tongue 14, the entire circular lock cylinder 10 can be limited from rotating reversely, and the external object cannot be separated from the locking connection portion 15, thus realizing the locking of the external object and preventing it from being taken away.

[0024] Certainly, the lock of the present invention is also provided with an elastic restoring member 30 that always exerts an elastic force on the guide shaft 20 in the direction opposite to the external force (it can be understood that this elastic force gradually increases as the external force increases, that is, the greater the distance the guide shaft 20 moves under the external force, the stronger this elastic force). By using this elastic force acting on the guide shaft 20, when the locking mechanism 40 withdraws from the lock tongue 14 and the external force applied to the guide shaft 20 is removed, it can automatically drive the guide shaft 20 to move reversely and return to the position before being subjected to the external force. Similar to the principle of rotating and locking under force, during the reverse reset movement of the guide shaft 20, due to the movement of the guide protrusion 21 in the guide groove 13, the guide shaft 20 can drive the entire circular lock cylinder 10 to rotate reversely and return to the natural state position when not subjected to external force. Thus, after unlocking, the external object can be removed from the locking connection portion 15 of the circular lock cylinder 10, and the linkage combination of the guide shaft 20 and the circular lock cylinder 10 can automatically reset to prepare for the next connection and locking with the external object.

[0025] For this set of linkage combination structures, specific reference can be made to, but not limited to, the following embodiment structures or solutions: In order to make the linkage between the round lock cylinder 10 and the guide slide shaft 20 smoother, in some embodiments of the present invention, the round lock cylinder 10 is sleeved on the outer periphery of the guide slide shaft 20, and the two are adaptively arranged with the same central axis. The guide slide protrusion 21 protrudes from the outer surface of the guide slide shaft 20, and the distance design between the round lock cylinder 10 and the guide slide shaft 20 needs to be adapted so that the guide slide protrusion 21 always extends into and can only move within the guide groove 13. Of course, this embodiment should not be understood as a limitation of the present invention. The combined design between the round lock cylinder 10 and the guide slide shaft 20 can also adopt other structures (for example, the sleeving positions of the round lock cylinder 10 and the guide slide shaft 20 are interchanged, and of course the structure needs to be adapted; and other solutions), but as long as the linkage method required to be protected by the present invention is adopted, it belongs to the protection scope of the present invention.

[0026] To facilitate the installation and linkage dynamics of this set of linkage combinations, further, for example, as Figure 1 and 2 shown in the embodiment structure, the round lock cylinder 10 includes a connected straight cylinder portion 11 and a rotating bearing portion 12; the guide groove 13 is obliquely opened on the curved surface of the straight cylinder portion 11, so that when the guide slide shaft 20 moves linearly along the central axis of the round lock cylinder 10, the position of the guide groove 13 is better adapted to the position of the guide slide protrusion 21 to drive the round lock cylinder 10 to rotate self - adaptively along with its sliding; the lock tongue 14 is arranged and protrudes from the outer peripheral surface of the rotating bearing portion 12, so that it can better adapt to the installation position of the locking mechanism 40, and does not occupy the outer peripheral space of the round lock cylinder 10, and the overall structure design is more optimized, which is beneficial to reducing the volume of the entire lock.

[0027] Further, in order to limit the guide slide shaft 20 to only move along the central axis direction, in some embodiments of the present invention, a fixed - positioned limit seat 22 is sleeved on the outer periphery of the guide slide shaft 20. The avoidance space opened on the limit seat 22 is slightly larger than the thickness of the guide slide shaft 20 to play a limiting role on the guide slide shaft 20; further, for the overall structural optimization of the lock, referring to the embodiment as Figure 2 shown, the limit seat 22 can be arranged at the end of the guide slide shaft 20 close to the rotating bearing portion 12; and the elastic recovery member 30 is connected between the limit seat 22 and the guide slide shaft 20. With such a design, it is convenient for the installation of each component and the force - applied movement and recovery movement of the guide slide shaft 20, and at the same time, it can be adapted to the linkage with the round lock cylinder 10, making the entire lock structure compact.

[0028] Further, the elastic recovery member 30 can adopt a spring, and in order to simultaneously take into account not hindering the movement of the guide slide shaft 20 and the structural optimization of the linkage combination, the guide slide shaft 20 can refer to the embodiment as Figure 2The shape structure of the illustrated embodiment: The main body part of the guide shaft 20 is shaped like a wooden handle grenade. The thicker part mainly adapts to the inner diameter of the round lock cylinder 10, which plays a certain auxiliary role in restricting the guide shaft 20 to only move linearly, and is also convenient for the guide convex to better adapt to the position of the guide groove 13. At the same time, it is the direct force-receiving point for the guide shaft 20 to receive external forces. The thinner part can be movably inserted into the limit seat 22, and a spring is sleeved on the outer periphery of the thinner part. The two ends of the spring respectively abut against the limit seat 22 and the thicker part of the guide shaft 20. Further, the thinner part of the guide shaft 20 can adopt the shape of a multi-prism, and the limit seat 22 is adapted to it, so as to better limit the guide shaft 20 and prevent it from rotating with the round lock cylinder 10. Further, in the natural state of the present invention, the spring is also in a certain elastic deformation state to ensure that a spring force opposite to the direction of the external force described in the present invention is always applied to the guide shaft 20, thereby ensuring that the lock has an automatic reset function.

[0029] For the convenience of installation, further, the guide projection 21 is detachably installed on the outer surface of the thicker part of the guide shaft 20. During installation, first put the guide shaft 20 into the round lock cylinder 10, and then align and install the guide projection 21 on the outer surface of the guide shaft 20. The convenient disassembly and assembly can be realized by referring to the structure of the threaded hole and the screw. Of course, other detachable connection structures can also be used.

[0030] For the convenience of operation and the optimization of the overall structure of the lock, in some embodiments of the present invention, refer to Figure 1 and 2 the illustrated embodiment. The locking connection part 15 is arranged at the end of the straight cylinder part 11 (the other end opposite to the rotating bearing part 12). A locking connection head 60 is installed on the external object introduced above; the locking connection head 60 is adaptively connected to the locking connection part 15 of the present invention. In the locked state described in the present invention, the external object can be locked to the assembly carrier installed with the present lock, and in the natural state, unlocking can be achieved and they can be separated from each other.

[0031] In some embodiments of the present invention, one of the locking connection part 15 of the present invention and the locking connection head 60 introduced above is provided with a plurality of convex tooth parts, and the other is provided with an avoidance notch adapted to the convex tooth parts; through the above linkage method, the following can be achieved during dynamic operation: in the natural state of the present invention, the convex tooth parts are aligned with the avoidance notch, so that an external object and the assembly carrier equipped with this lock can be mutually butted and inserted or separated; in the locked state of the present invention, the convex tooth parts are misaligned with the avoidance notch, and the two cannot be separated, so as to lock the external object on the assembly carrier equipped with this lock. Of course, it can be understood that the functional connection structure for locking connection and unlocking separation with an external object through the locking connection part 15 of this lock of the present invention is not limited to this, and other connection structures that can be adapted to this lock can also be referred to. And for the connection structure introduced in this paragraph, for example, as Figures 1 - 8 shown in the embodiment, since the locking connection head 60 is installed on the external object, lift the external object to align the locking connection head 60 and insert it into the locking connection part 15 at the end of the round lock cylinder 10. Operate the external object to apply the external force described in the present invention to the guide slide shaft 20 through the locking connection head 60, and push the guide slide shaft 20 to move along the central axis and towards the direction of the limit seat 22. The guide slide protrusion 21 will drive the round lock cylinder 10 to rotate adaptively along the guide groove 13, so that the avoidance notch of the locking connection part 15 is angularly misaligned with the convex tooth part of the locking connection head 60, and after the lock tongue 14 rotates a certain angle (preset according to the adaptation structure of the linkage combination) along with the round lock cylinder 10, the locking mechanism 40 can automatically pop into the range that hinders the return rotation of the lock tongue 14, so that the external object equipped with the locking connection head 60 cannot be pulled out from the assembly carrier equipped with this lock. At this time, it is the locked state described in the present invention (refer to Figure 5 ). Then, control the locking mechanism 40 to withdraw from the lock tongue 14, and there is no obstacle for the lock tongue 14 to return and recover (refer to Figure 7 ). Only need to pull the external object out of this lock. During the process of the locking connection head 60 retreating from the round lock cylinder 10 in the reverse direction (that is, the process of canceling the external force described in the present invention), the compressed spring (elastic recovery part 30) releases potential energy, and drives the guide slide shaft 20 to move in the reverse direction to return to the position in the natural state in the form of elastic force. During the recovery process, the action of the guide slide protrusion 21 on the guide groove 13 drives the round lock cylinder 10 to rotate in the reverse direction to return to the natural state (refer to Figure 3 , and the principle is the same as the locking linkage of the linkage combination).

[0032] To ensure the reliability of this lock in the application scenario, in some embodiments of the present invention, two monitoring switches are arranged at intervals within the rotation range of the lock tongue 14; one is used to monitor whether the lock tongue 14 returns to the preset position in the natural state when in the natural state (for example, as Figure 3In the illustrated embodiment, the locking tongue 14 in this state triggers the first monitoring switch 51 to indicate that the locking tongue 14 is in the normal condition of being restored in place; conversely, if in this natural state, the position of the locking tongue 14 does not trigger the first monitoring switch 51, it indicates that the locking tongue 14 is not reset in place, that is, the entire round lock cylinder 10 is not reset in place either, which is a fault state); and / or used to monitor whether the locking mechanism 40 can successfully automatically limit the return rotation of the locking tongue 14 in the locked state (for example, as Figure 5 In the illustrated embodiment, the locking tongue 14 in this state is limited to one side by the locking mechanism 40, and the other side of the locking mechanism 40 triggers the first monitoring switch 51 to indicate the normal condition that the locking mechanism 40 is locked in place; conversely, if in this locked state, the locking mechanism 40 does not trigger the first monitoring switch 51, it indicates that the locking mechanism 40 is not locked in place, and foreign objects can still be removed from this lock, which is a fault state); and the other monitoring switch is used to monitor whether the locking tongue 14 is driven to rotate to the preset position in the locked state (for example, as Figure 5 In the illustrated embodiment, the locking tongue 14 in this state has been driven to rotate to the position where the second monitoring switch 52 is triggered, to indicate that the rotation angle of the round lock cylinder 10 has caused the locking connection part 15 to rotate to the position of the locked state described in the present invention; it is also to monitor whether the insertion connection between the foreign object and this lock enters the preset position). Of course, for better identification and / or intelligent management, these two monitoring switches can also be connected to some alarm identification devices, control systems, etc. for further processing according to requirements.

[0033] The locking mechanism 40 of the present invention can be realized that when the guide sliding shaft 20 is stressed and enters the locked state, it can automatically spring into the range of limiting the return rotation of the locking tongue 14. The following embodiments can be referred to but are not limited to: The locking mechanism 40 includes a locking slider 41, an automatic rod 42, and a control rod part 43; the automatic rod 42 is respectively connected to the locking slider 41 and the control rod part 43; the automatic rod 42 always automatically applies a thrust force to the locking slider 41. In the case of no other force acting, the thrust force is sufficient to drive the locking slider 41 into the range of limiting the return rotation of the locking tongue 14; the control rod part 43 can adopt an electric control structure and / or a mechanical control structure (the control rod part 43 in the embodiment of the specification drawings adopts a dual-control structure); through the control rod part 43, the automatic rod 42 and the locking slider 41 can be driven to withdraw from the range of limiting the return rotation of the locking tongue 14. For example, it can be referred to as Figure 3 、 57, specifically, the automatic rod 42 includes a straight rod and a spring, the spring is sleeved outside the straight rod, and after storing elastic potential energy, it is connected between the control rod portion 43 and the locking slider 41 (of course, the two ends of the spring can also be connected between the control rod portion 43 and the straight rod, which can also achieve the effect of outputting elastic force); under the elastic force of the spring, the straight rod always tends to move away from the control rod portion 43; and the protruding lock tongue 14 is always in conflict with the locking slider 41 before entering the locked state (refer to Figure 3 ), so the relative position of the locking slider 41 and the straight rod relative to the control rod portion 43 will change with the rotation position of the lock tongue 14 (further, the contact surface between the locking slider 41 and the lock tongue 14 can be designed with an adaptive shape structure and assembly position according to their relative motion trajectory, for example Figure 3 and 5 As shown, the contact surface of the locking slider 41 is inclined, while the contact surface of the lock tongue 14 is a circular pulley. When the lock enters the locked state from the natural state, the pulley of the lock tongue 14 slides from the highest end of the inclined surface of the locking slider 41 to the lowest end and slides away from the inclined surface of the locking slider 41, so that the locking slider 41 can gradually approach the range of travel that can limit the return rotation of the lock tongue 14 as the lock tongue 14 rotates. In addition, the relative position of the straight rod relative to the control rod 43 can be controlled by the control rod 43, thereby changing the relative position of the locking slider 41 relative to the lock tongue 14. Therefore, in the locked state (refer to Figure 5 ), the straight rod can be pulled back by the control rod portion 43 to make the locking slider 41 withdraw from the lock tongue 14, thereby achieving unlocking (refer to Figure 7 It is understandable that the electric control structure and / or mechanical control structure adopted by the control rod portion 43 can be selected and adapted according to the functional requirements of the lock in the application scenario.

[0034] In order to adapt to the application scenarios of some locks - after the unlocking action is performed by the control rod part 43 in the locked state, the locking mechanism 40 needs to maintain the unlocked state position until the lock tongue 14 returns to the original position with the circular lock cylinder 10, and the unlocked state is cancelled; or the control rod part 43 performs the unlocking operation again. Therefore, in some embodiments of the present invention, a positioning groove is provided on the locking slider 41; the locking mechanism 40 also includes a positioning rod 44, the first end 441 of the positioning rod is fixed, and the second end 442 of the positioning rod is movable in and out of the positioning groove relative to the locking slider 41 and as the locking slider 41 moves; in the locked state, when the locking slider 41 is controlled by the control rod part 43 to withdraw from the range that can limit the return rotation of the lock tongue 14, the second end 442 of the positioning rod enters the positioning groove to position the locking slider 41 and the automatic rod 42 at this position; and at this time, if the external force on the guide slide shaft 20 is cancelled, the second end 442 of the positioning rod can be disengaged from the positioning groove during the reverse rotation process when the lock tongue 14 returns to its natural state. For example, refer to Figure 7and 8 In the embodiment shown, in this state of the figure, it can be understood that the first end 441 of the positioning rod is fixed on the housing of the lock and does not move. The straight rod and the locking slider 41 always tend to move away from the control rod portion 43 under the action of the spring. Therefore, when the control rod portion 43 performs an unlocking operation once, the locking slider 41 moves towards the control rod portion 43, causing the second end 442 of the positioning rod to enter the positioning groove. The length of the positioning rod 44 can be utilized to position the locking slider 41 in the middle of its travel and not hinder the return rotation of the lock tongue 14. During the process of the external object and the installed locking connector 60 being pulled away from this lock, the return rotation of the lock tongue 14 can push the locking slider 41 a short distance towards the control rod portion 43, causing the second end 442 of the positioning rod to exit the positioning groove. The locking slider 41 will be pushed by the elastic force of the automatic rod 42 towards and against the lock tongue 14 to return to the natural state position when the lock of this embodiment is unloaded. For a lock similar to the solution of this embodiment, it can be realized that only by the control rod portion 43 performing an unlocking operation once to move the locking slider 41 out of the range of the return rotation of the lock tongue 14, the cooperation between the positioning rod 44 and the positioning groove can keep the locking mechanism 40 in the unlocked state to meet the requirements of some application scenarios for a longer unlocking time. At the same time, during the process of the external force being withdrawn in the present invention, that is, when the external object is pulled away from this lock and the set linkage combination returns and restores, the positioning rod 44 can exit the positioning groove to cancel the unlocked state by the way, further upgrading the multi-functional linkage of this lock, with a clever design and practical functions.

[0035] Furthermore, in order to make the linkage dynamics of the positioning rod 44 entering and exiting the positioning groove smoother, in some embodiments of the present invention, (it should be noted that one end of the positioning rod 44 is fixed on the outer shell 70 of the lock, so it is always the movement of the locking slider 41 that causes the relative position of the second end 442 of the positioning rod with respect to the locking slider 41 to change, that is, the position of the positioning rod 44 on the lock does not shift.) Two avoidance chutes are respectively communicated at both ends of the positioning groove. The two avoidance chutes are respectively the two sliding strokes of the second end 442 of the positioning rod (relative to the locking slider 41) before entering the positioning groove and after leaving the positioning groove. By respectively arranging avoidance chutes at both ends of the positioning groove, the relative movement trajectory of the second end 442 of the positioning rod and the locking slider 41 can be accurately guided and controlled, thereby accurately ensuring that this function of the lock is not prone to BUGs or failures during practical use.

[0036] Further, in order to better ensure the repeated cyclic operation of the locking mechanism 40, in some embodiments of the present invention, the two avoidance sliding grooves and the positioning groove form a communicating annular groove (it can be understood that it is not limited to a circular ring or a completely enclosed ring), and the second end 442 of the positioning rod is limited to slide in only one direction in the annular groove, which can more accurately control the dynamic movement direction of the second end 442 of the positioning rod and the pause position of each state, thereby avoiding failures.

[0037] Specifically, reference can be made to, but not limited to, the following embodiments: On the basis of the previous paragraph, high and low steps are formed at the junction of each slot section of the annular groove; at the junction of any slot section, the slot section where the second end 442 of the positioning rod is located is always the high-order surface of the high and low steps, and the next slot section that the second end 442 of the positioning rod is about to slide into is the low-order surface of the high and low steps. Then, the second end 442 of the positioning rod can only fall from the previous high-order surface to the next low-order surface each time it passes through the slot section junction. In this way, when the second end 442 of the positioning rod slides along the track of the annular groove, it cannot slide back to the previous slot section in the reverse direction, thereby realizing the one-way movement limitation. In practical applications, with the repeated operation of the control rod portion 43, the second end 442 of the positioning rod always slides in a regular order, so that the locking slider 41 always changes its position regularly, and no disorder will occur to cause failures.

[0038] Further, in order to adapt to the functional requirements, in some embodiments of the present invention, the junction of each slot section is designed such that the two slot sections form a certain angle, so that the second end 442 of the positioning rod can better conform to the linear movement of the locking slider 41 and slide unidirectionally along the inner wall of the inclined slot section, and can better guide the second end 442 of the positioning rod to slide from the previous slot section into the next advancing slot section.

[0039] In order to improve the stability of the locking mechanism 40 to maintain the unlocked state after performing an unlocking operation, in some embodiments of the present invention, the positioning groove adopts a V-shaped groove 45; the sliding stroke of the second end 442 of the positioning rod before entering the positioning groove is the first avoidance sliding groove 46; the starting end of the front half slot section 451 of the V-shaped groove 45 is inclined towards the center line of the V-shaped groove 45, and the front half slot section 451 is connected to the end of the first avoidance sliding groove 46, so as to better ensure that as the locking slider 41 moves, the second end 442 of the positioning rod can be guided to the center of the V-shaped groove 45 regardless of which side inner wall of the front half slot section 451 it touches, so as to ensure that the second end 442 of the positioning rod can be accurately introduced and clamped at the center position of the V-shaped groove 45. For reference, see Figure 9The embodiments shown. To further ensure that the second end 442 of the positioning rod cannot slide reversely in the V-shaped groove 45, a high-low step as introduced above is also formed at the central concave portion of the V-shaped groove 45. The end section of the front half groove section 451 is a high-order surface, and the starting section of the rear half groove section 452 is a low-order surface.

[0040] To adapt to the movement laws of the automatic rod 42 and the locking slider 41 in the locking mechanism 40, the annular groove can refer to the specific embodiments shown in Figure 6 and 9 Further, at the starting end of the first avoidance chute 46, a stay groove 461 extends outward for the second end 442 of the positioning rod to stay in the locked state described in the present invention, and this section of the stay groove 461 can better adapt to the linear movement of the locking slider 41. A return angle 471 is also provided near the starting end of the second avoidance chute 47 (refer to Figure 9 ). When the second end 442 of the positioning rod is in the unlocked state while staying in the V-shaped groove 45 (refer to Figure 7 and 8 for the state positions); when the lock tongue 14 rotates back, it pushes the locking slider 41 to move a short distance in the direction of the control rod portion 43. After the second end 442 of the positioning rod slides from the rear half groove section 452 of the V-shaped groove 45 into the second avoidance chute 47, due to the cancellation of the external force, the lock tongue 14 returns to the natural state position, and the locking mechanism 40 also cancels the unlocked state and turns into the natural state; and under the elastic force of the automatic rod 42, the locking slider 41 always abuts against the lock tongue 14 and stays at the natural state position, ready to enter the locked state at any time as the lock tongue 14 rotates when an external object is inserted next time (refer to Figure 3 for the state position). Therefore, in the natural state, the second end 442 of the positioning rod always stays at this return angle 471 (refer to Figure 4 for the state position). Of course, the stay angle also guides and changes the direction of the second end 442 of the positioning rod to adapt to the movement of the locking slider 41.

[0041] Therefore, the principle of the linkage dynamic change for the recyclable operation of the lock in this embodiment is as follows: When the lock of this embodiment is in the natural state without load, under the elastic force of the elastic restoring member 30, the guide sliding protrusion 21 is located at the upper end of the guide groove 13 (refer to Figure 1 . It can be understood that this orientation term is relative to the downward movement of the guide sliding shaft 20 under external force). The lock tongue 14 is kept at the natural state position and triggers the first monitoring switch 51. The locking slider 41 abuts against the lower part of the lock tongue 14 under the action of the automatic rod 42; while the second monitoring switch 52 is in the off state (refer to Figure 3 ); the second end 442 of the positioning rod stays at the return angle 471 (refer to Figure 4); When an external object is aligned and inserted into the round lock cylinder 10, the upper locking connector 60 applies a force to the guide slide shaft 20, causing the guide slide shaft 20 to move closer to the limit seat 22. The guide slide protrusion 21 slides along the inner wall of the guide groove 13 to drive the entire round lock cylinder 10 to rotate. During this rotation process, the lock tongue 14 rotates along the inclined top surface of the locking slider 41 (downhill movement; refer to the transition from Figure 3 dynamic change to Figure 5 ). Since the top surface of the locking slider 41 is inclined, the locking slider 41 gradually approaches the round lock cylinder 10 as the lock tongue 14 rotates towards the second monitoring switch 52. Until before the guide slide shaft 20 is pushed to the farthest moving distance (to better ensure that the locking slider 41 can be automatically locked successfully), the rotation of the lock tongue 14 has left the top surface of the locking slider 41. Therefore, the locking slider 41 will be bounced into the range that obstructs the return rotation of the lock tongue 14 by the automatic rod 42. Thus, when the external object is docked and inserted into this lock, automatic locking can be successfully achieved. At this time, it is in the locked state. The lock tongue 14 triggers the second monitoring switch 52 to monitor whether the external object is inserted in place (the preset stable connection position, that is, the external object is inserted to the bottom) by the position of the lock tongue 14 at this time; the locking slider 41 triggers the first monitoring switch 51 to indicate that the locking is in place (refer to Figure 5 ); The second end 442 of the positioning rod slides into the stop groove 461 of the first avoidance chute 46 through the second avoidance chute 47 as the locking slider 41 moves upward (refer to Figure 6 ). Then, operate the control rod part 43 to pull the automatic rod 42, so that the locking slider 41 leaves the return rotation stroke of the lock tongue 14; as the locking slider 41 moves downward, the second end 442 of the positioning rod falls into the front half groove section 451 of the V-shaped groove 45 through the first avoidance chute 46. Since the starting end of the front half groove section 451 is inclined towards the center of the V-shaped groove 45, after the control rod part 43 completes the operation of pulling once (only move once), the elastic force of the automatic rod 42 drives the locking slider 41 to move away from the control rod part 43. At this time, the second end 442 of the positioning rod just slides to the center position of the V-shaped groove 45 along the front half groove section 451 (refer to Figure 8), since the first end 441 of the positioning rod and its length are fixed, the two ends of the positioning rod 44 can be used to position the locking slider 41 and the automatic rod 42 at this state position, so as to maintain the unlocked state and provide sufficient time for the user to operate and remove foreign objects. Finally, when the foreign object is removed, under the action of the elastic restoring member 30, the guide shaft 20 is driven to move backward. During the reset process, similarly, the guide protrusion 21 drives the round lock cylinder 10 to rotate backward to the position in the natural state, including the locking tongue 14 rotating back and moving uphill along the inclined top surface of the locking slider 41. Therefore, the locking slider 41 is pushed a short distance in the direction of the control rod portion 43 by the locking tongue 14. This small displacement enables the second end 442 of the positioning rod to move away from the center of the V-shaped groove 45 along with the movement of the locking slider 41 and slide out along the rear half groove section 452 and then fall into the return angle 471 (refer to Figure 4 ), and re-enter the natural state to prepare for the next insertion of a foreign object. In this way, the dynamic cycle of "inserting a foreign object to enter the locked state - operating the control rod portion 43 once to maintain the unlocked state - removing the foreign object and rotating to the natural state" of this lock is completed.
