Description

Technical Field

[0001] The utility model relates to the technical field of firearm safety locks, in particular to a locking mechanism and a firearm lock with enhanced stability. Background Art

[0002] The prior art discloses a variety of different mechanisms to prevent the accidental removal of a weapon from a gun lock. Most of the prior art structures are characterized by complex and cumbersome mechanisms, which are clumsy, inconvenient, and difficult to operate, especially difficult to achieve the rapid deployment of a weapon from a gun lock. Although such safety locks are required in all types of firearms to reduce the risk of unauthorized, inadvertent, or accidental opening of the gun lock to access the weapon. However, a gun lock that ensures higher security of the weapon usually results in a slower extraction or slower deployment of the weapon; while a gun lock that provides rapid deployment of the weapon usually results in lower security. Therefore, users usually need to make an undesirable trade-off between two essential characteristics, namely security and rapid deployment. So it is very necessary to use a gun lock that can provide high security and rapid deployment without compromising any essential features.

[0003] For example, the Chinese patent document with the publication number CN202403610U discloses a firearm trigger lock, which consists of an upper locking sleeve, an upper rubber pad, a lower rubber pad, a lower locking sleeve, and a key. Its feature is that the upper rubber pad is sleeved inside the upper locking sleeve, the lower rubber pad is sleeved inside the lower locking sleeve, a lock core is installed inside the lock head of the upper locking sleeve, a lock core column is connected thereto, and together with the lock core sleeve, it is inserted into the lock core column groove of the lower locking sleeve.

[0004] Although the trigger locks currently on the market can prevent unauthorized abuse, when an authorized user needs to use it, the gun lock product must be unlocked first, and then the entire lock body must be removed before the user can take out the firearm for shooting, which seriously affects the speed of the user to deploy the firearm.

[0005] When designing a new type of firearm lock that is both safe and convenient to deploy, how to enhance the stability of the locking mechanism is also a technical problem to be solved. Summary of the Utility Model

[0006] The utility model aims to provide a technical solution to overcome the above-mentioned deficiencies.

[0007] The present utility model provides a locking mechanism for enhancing stability, which is used to lock a lock beam mechanism. It includes a lock housing, a lock hook assembly, a lock tongue assembly, and an unlocking assembly. One end of the lock tongue assembly is rotatably connected to the lock housing, and the other end is provided with a lock groove, which is used to engage with the lock beam column of the lock beam mechanism to form a lock on the lock beam mechanism. One side of the lock groove is provided with an extension arm, and the extension arm and the lock hook assembly cooperate with each other to form a separable connection, so that the lock hook assembly can limit the lock tongue assembly. The unlocking assembly is installed on the lock housing and can drive the lock hook assembly to rotate a certain angle, thereby releasing the limit operation on the lock tongue assembly, and further enabling the lock tongue assembly to synchronously release the locking operation on the lock beam mechanism.

[0008] As a further scheme of the present utility model: The lock housing is provided with a first rotating column, the lock tongue assembly is rotatably connected to the first rotating column and is provided with a torsion spring. The torsion spring is sleeved on the first rotating column, one end of which abuts against the lock housing, and the other end abuts against the extension arm. The torsion force of the torsion spring drives the lock tongue assembly to maintain an unlocked state of rotating outwards.

[0009] As a further scheme of the present utility model: The lock housing is further provided with a second rotating column, the lock hook assembly is rotatably connected to the second rotating column, and the lock hook assembly is provided with a lock hook arm corresponding to the position of the extension arm, and the lock hook arm can engage with the extension arm.

[0011] As a further scheme of the present utility model: The lock hook assembly is further provided with an unlocking driven arm, and the unlocking driven arm can be driven by the unlocking assembly, so that the lock hook assembly rotates a certain angle to release the lock tongue assembly.

[0012] As a further scheme of the present utility model: The unlocking assembly is provided with a mechanical unlocking mechanism, which includes a mechanical lock core, a first gear, a first rack, and a first transmission block. The mechanical lock core is installed on the lock housing, and the first gear is sleeved on the linkage shaft of the mechanical lock core and is thus driven by the linkage shaft to rotate synchronously. One end of the first rack is meshed with the first gear, and the other end is provided with a sliding shaft. The first transmission block is rotatably connected to the lock housing, and a strip-shaped chute is provided at the position corresponding to the sliding shaft. The strip-shaped chute is sleeved on the sliding shaft, and the sliding shaft can slide along the inner wall of the strip-shaped chute, thereby driving the first transmission block to rotate a certain angle. The first transmission block is provided with an unlocking driving arm corresponding to the unlocking driven arm. The rotating first transmission block drives the unlocking driving arm to pry the unlocking driven arm, so that the unlocking driven arm drives the lock hook assembly to rotate a certain angle, and further enables the lock hook arm to release the engagement with the extension arm, and the lock tongue assembly returns to the unlocked state.

[0013] As a further solution of the present utility model: The unlocking assembly further comprises an electric unlocking mechanism, which includes an unlocking motor, a second gear and a second rack. The unlocking motor is fixedly connected to the lock housing, the second gear is fixedly connected to the output shaft of the unlocking motor, one end of the second rack is meshed with the second gear, and the other end thereof is provided with a push block. An unlocking bump is provided at a position of the lock hook arm corresponding to the push block. The unlocking bump abuts against the push block and can be rotated by a certain angle under the drive of the push block, thereby driving the lock hook assembly to rotate by a certain angle synchronously, and further enabling the lock hook arm to release the clamping of the extension arm, so that the lock tongue assembly returns to the unlocking state.

[0014] As a further solution of the present utility model: The lock hook assembly further comprises a locking arm and a compression spring. One end of the compression spring abuts against the lock housing, and the other end thereof abuts against the locking arm. The elastic force of the compression spring drives the lock hook assembly to maintain the limiting state of the lock tongue assembly.

[0015] As a further solution of the present utility model: It further comprises a microswitch and a control module. The microswitch is installed at a position of the lock housing corresponding to the locking arm, and the microswitch is electrically connected to the control module. When the lock hook assembly forms a locking state with the lock tongue assembly, the locking arm can trigger the microswitch, so that the microswitch sends a corresponding electronic signal to the control module.

[0016] The present utility model further provides a firearm lock, which includes the above-mentioned locking mechanism for enhancing stability, and further includes a lock beam mechanism and a lock body assembly. The lock body assembly is detachably and fixedly connected to an external firearm. The lock beam mechanism locks or unlocks the trigger part of the firearm, and the locking mechanism locks or unlocks the lock beam mechanism.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. By providing an independent lock groove and a lock beam column, and using the lock groove of the lock tongue assembly to independently lock the lock beam column, the locking strength of the locking mechanism can be improved, and its stability can also be improved. Because the lock tongue assembly is sleeved on the first rotating column, and the two sides of the lock groove have side edges with a certain thickness, which can strengthen the locking effect on the lock beam column, and its extension arm can also form a stable locking structure with the lock hook arm, further increasing the difficulty of forced unlocking.

[0019] 2. By further providing a hook-shaped bump, the locking strength of the extension arm is further improved, and at the same time, its locking stability with the lock beam column is enhanced. At the same time, a compression spring is also provided to drive the lock hook assembly to maintain the best limiting effect on the lock tongue assembly, improving its locking strength and stability.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a locking mechanism for enhancing stability is used to lock the lock beam mechanism 10, and includes a lock housing 31, a lock hook assembly 40, a lock tongue assembly 50 and an unlock assembly 60. The lock hook assembly 40 and the lock tongue assembly 50 are both rotatably connected to the lock housing 31. One end of the lock tongue assembly 50 is rotatably connected to the lock housing 31, and the other end thereof is provided with a lock groove 51. The lock groove 51 is used to engage with the lock beam column 11 of the lock beam mechanism 10, so as to form a lock on the lock beam mechanism 10. One side of the lock groove 51 is provided with an extension arm 52. The extension arm 52 and the lock hook assembly 40 cooperate with each other to form a separable snap connection, so that the lock hook assembly 40 can perform a limiting operation on the lock tongue assembly 50, and thus cooperate with each other to form a locking operation on the lock beam mechanism 10. The unlock assembly 60 is installed on the lock housing 31 and can drive the lock hook assembly 40 to rotate a certain angle, so as to release the limiting operation on the lock tongue assembly 50, and further enable the lock tongue assembly 50 to synchronously release the locking operation on the lock beam mechanism 10.

[0033] Specifically, in order to improve the safety of firearms, firearm locks are usually used to lock the firearms to prevent their unauthorized use. For example, in a firearm lock, a lock body assembly 20 can be detachably fixed to the corresponding Picatinny rail of the firearm, and then a lock beam mechanism 10 rotatably connected to the lock body is used to lock the trigger part of the firearm, thereby improving the safety of the firearm. In order to lock the lock beam mechanism 10 itself, a corresponding locking mechanism 30 needs to be provided to lock its lock beam column 11 to ensure that the lock beam mechanism 10 cannot be unlocked without authorization in the locked state. In order to improve the stability of the locking mechanism 30, a lock tongue assembly 50 can be provided, and a lock groove 51 with a certain depth can be provided on the lock tongue assembly 50 to completely snap the lock beam column 11 into it to prevent the lock beam column 11 from being violently opened.

[0034] Secondly, an extension arm 52 can be provided on one side of the lock groove 51. By using the clamping connection between the extension arm 52 and the lock hook assembly 40, a detachable clamping connection is formed for the lock tongue assembly 50, and the unlocking direction of the extension arm 52 is generally parallel to the radial direction of the lock hook assembly 40, that is, the unlocking stress formed by the extension arm 52 on the lock hook arm 41 is distributed along the radial direction of the lock hook assembly 40. Thus, the unlocking stress during violent unlocking can be mainly concentrated on the second rotating column 34, further enhancing the stability of the locking mechanism 30 and preventing the locking mechanism 30 from being violently unlocked.

[0035] As Figure 1 and Figure 2 shown, preferably, the lock shell 31 is provided with a first rotating column 32, the lock tongue assembly 50 is rotatably connected to the first rotating column 32, and a torsion spring 33 is provided. The torsion spring 33 is sleeved on the first rotating column 32, one end of which abuts against the lock shell 31, and the other end abuts against the extension arm 52. The torsion of the torsion spring 33 drives the lock tongue assembly 50 to maintain an unlocked state of rotating outward.

[0036] Specifically, the torsion of the torsion spring 33 can drive the lock tongue assembly 50 to rotate towards the outside of the lock shell 31, thereby performing a release operation on the lock beam column 11, enabling the lock beam column 11 to disengage from the lock groove 51, and further releasing the locking operation on the lock beam mechanism 10 to make the lock beam mechanism 10 form an unlocked state. Similarly, when the lock tongue assembly 50 maintains an unlocked state of rotating outward, its lock groove 51 is also in an open state facing the outside of the lock shell 31. When it is necessary to lock the lock beam mechanism 10, the lock beam mechanism 10 can be rotated first, and then the lock beam column 11 is snapped into the lock groove 51, and the lock tongue assembly 50 is pushed to rotate a certain angle to make the extension arm 52 form a clamping connection with the lock hook assembly 40, thereby forming a rotational restriction on the lock tongue assembly 50, and further performing a locking operation on the lock beam column 11 again to make the lock beam mechanism 10 form a locked state.

[0037] Secondly, in order to enable the extension arm 52 to better drive the hook assembly 40 to rotate a certain angle when driven by the locked beam column 11, preferably, a first ramp 53 is provided at the position where the extension arm 52 contacts the hook assembly 40. The first ramp 53 can be set as an inclined plane with a consistent angle or as an arc surface bent at a certain angle, so that when it rotates following the extension arm 52, it can better drive the hook assembly 40.

[0038] As Figure 2 and Figure 5 shown, preferably, the lock housing 31 is further provided with a second rotating column 34. The middle position of the hook assembly 40 is rotatably connected to the second rotating column 34. A hook arm 41 is provided at the position of the hook assembly 40 corresponding to the extension arm 52, and the hook arm 41 can latch the extension arm 52. At the position corresponding to latching the extension arm 52, the hook arm 41 is provided with a hook-shaped protrusion 42, and the hook-shaped protrusion 42 can latch the extension arm 52 to limit it at a preset position.

[0039] Specifically, the hook arm 41 can form a hook-shaped protrusion 42 to latch the extension arm 52. It can also be understood that a recessed space is formed between the hook-shaped protrusion 42 and the hook arm 41, so that when the extension arm 52 is locked, it can be received in the recessed space, and the hook-shaped protrusion 42 can prevent the extension arm 52 from leaving the recessed space.

[0040] In addition, a second ramp 43 is provided at the position of the hook-shaped protrusion 42 corresponding to the first ramp 53 of the extension arm 52. The second ramp 43 and the first ramp 53 cooperate with each other, so that when the extension arm 52 rotates, it can better drive the hook assembly 40 to rotate a certain angle, so that the front end of the extension arm 52 can enter the recessed space. At the same time, the elastic force of the compression spring 48 of the hook assembly 40 can drive the hook assembly 40 to rotate reversely by a certain angle, so as to limit the extension arm 52 inside the recessed space and complete the locking operation.

[0041] As Figure 2 、 Figure 3 and Figure 5 shown, preferably, the hook assembly 40 is further provided with an unlocking driven arm 46, and the unlocking driven arm 46 can be driven by the unlocking assembly 60, so that the hook assembly 40 rotates a certain angle to release the locking tongue assembly 50.

[0042] Specifically, the unlocking driven arm 46 is arranged on the side of the hook assembly 40 facing away from the locking tongue assembly 50, so as to facilitate the setting of a corresponding unlocking mechanism on the side where the unlocking driven arm 46 is located to perform an unlocking operation on the unlocking driven arm 46.

[0043] As Figure 2 、 Figure 3 and Figure 5As shown, preferably, the unlocking assembly 60 is provided with a mechanical unlocking mechanism 61. The mechanical unlocking mechanism 61 is provided with a mechanical lock core 62, a first gear 63, a first rack 64 and a first transmission block 66. The mechanical lock core 62 is installed in the lock housing 31. The first gear 63 is sleeved on the linkage shaft of the mechanical lock core 62 and is thus driven by the linkage shaft to rotate synchronously. One end of the first rack 64 is meshed with the first gear 63, and the other end is provided with a sliding shaft 65. The first transmission block 66 is rotatably connected to the lock housing 31. A strip-shaped chute 67 is provided at a position corresponding to the sliding shaft 65. The strip-shaped chute 67 is sleeved on the sliding shaft 65, and the sliding shaft 65 can slide along the inner wall of the strip-shaped chute 67, thereby driving the first transmission block 66 to rotate by a certain angle. An unlocking active arm 68 is provided at a position of the first transmission block 66 corresponding to the unlocking driven arm 46. The rotating first transmission block 66 drives the unlocking active arm 68 to pry the unlocking driven arm 46, so that the unlocking driven arm 46 drives the lock hook assembly 40 to rotate by a certain angle, and further the lock hook arm 41 releases the clamping of the extension arm 52, and the lock tongue assembly 50 returns to the unlocked state.

[0044] Specifically, in order to enable the unlocking active arm 68 to better drive the unlocking driven arm 46 to rotate by a certain angle, preferably, a third slope 69 can also be provided on the unlocking active arm 68 to drive the unlocking driven arm 46 by using the third slope 69.

[0045] In addition, the lock housing 31 is further provided with a limiting protrusion 35. The limiting protrusion 35 is arranged on the other side of the unlocking active arm 68 facing the unlocking driven arm 46, so as to form a reverse limiting effect on the unlocking active arm 68. When the lock hook assembly 40 is in the locked state, when the unlocking driven arm 46 drives the unlocking active arm 68 to rotate in the reverse direction, it can form a limit on the unlocking active arm 68 to prevent the unlocking driven arm 46 from disengaging.

[0046] As Figure 4 and Figure 5 shown, preferably, the unlocking assembly 60 is further provided with an electric unlocking mechanism 71. The electric unlocking mechanism 71 is provided with an unlocking motor 72, a second gear 73 and a second rack 74. The unlocking motor 72 is fixedly connected to the lock housing 31. The second gear 73 is fixedly connected to the output shaft of the unlocking motor 72. One end of the second rack 74 is meshed with the second gear 73, and the other end is provided with a pushing block 75. An unlocking convex block 44 is provided at a position of the lock hook arm 41 corresponding to the pushing block 75. The unlocking convex block 44 abuts against the pushing block 75 and can be driven by the pushing block 75 to rotate by a certain angle, thereby driving the lock hook assembly 40 to rotate synchronously by a certain angle, and further the lock hook arm 41 releases the clamping of the extension arm 52, and the lock tongue assembly 50 returns to the unlocked state.

[0047] Specifically, when the unlocking motor 72 operates, it can drive the second gear 73 to rotate synchronously, thereby driving the second rack 74 to move synchronously a certain distance, enabling the pushing block 75 to synchronously push the unlocking lug 44 to generate a certain displacement, and further driving the lock hook assembly 40 to rotate a certain angle around the second rotating column 34. That is, the lock hook arm 41 can be rotated synchronously a certain angle, thereby releasing the clamping state of the extension arm 52, enabling the lock tongue assembly 50 to rotate outward a certain angle under the torsion of the torsion spring 33, and further releasing the locking of the lock beam column 11, so that the lock beam assembly can complete the corresponding unlocking operation.

[0048] In addition, in order to make the driving of the unlocking lug 44 by the pushing block 75 smoother and enable the lock hook assembly 40 to rotate a certain angle synchronously, preferably, a fourth ramp 45 can be provided at the position of the unlocking lug 44 corresponding to the pushing block 75, so that the pushing block 75 can drive the lock hook arm 41 by using the fourth ramp 45 to rotate a certain angle to complete the unlocking operation. The fourth ramp 45 extends substantially along the radial direction of the lock hook assembly 40 to better drive the rotation of the lock hook assembly 40.

[0049] As Figures 1 to 3 shown, preferably, the lock hook assembly 40 is further provided with a locking arm 47 and a compression spring 48. One end of the compression spring 48 abuts against the lock housing 31, and the other end abuts against the locking arm 47. The elastic force of the compression spring 48 drives the lock hook assembly 40 to maintain the limiting state of the lock tongue assembly 50.

[0050] Specifically, the locking arm 47 is preferably arranged on the side of the lock hook assembly 40 facing the lock tongue assembly 50, so as to facilitate the arrangement of the compression spring 48 and the microswitch 21. The compression spring 48 can make the lock hook assembly 40 rotate around the second rotating column 34, so that it tends to rotate towards the state of locking the lock tongue assembly 50 until the locking arm 47 abuts against the microswitch 21, thereby limiting the lock hook arm 41 in the locked state.

[0051] As Figure 5 and Figure 6 shown, preferably, it further includes a microswitch 21 and a control module 22. The microswitch 21 is installed at the position of the lock housing 31 corresponding to the locking arm 47. The microswitch 21 is electrically connected to the control module 22. When the lock hook assembly 40 forms a locking state for the lock tongue assembly 50, the locking arm 47 can trigger the microswitch 21, so that the microswitch 21 sends a corresponding electronic signal to the control module 22.

[0052] Specifically, a push-button microswitch 21 can be used to detect the locked state between the locking hook assembly 40 and the locking tongue assembly 50, so as to determine whether the current state of the lock beam mechanism 10 is the locked state or the unlocked state. Since the electric unlocking mechanism 71 usually also needs to be provided with a corresponding user authentication module, in which the user authentication module can use one or more authentication methods such as password authentication, fingerprint authentication, face authentication, etc. in the prior art to confirm the authorized user before performing the electric unlocking operation. The control module 22 can be electrically connected to the electric unlocking mechanism 71 and the user authentication module respectively, and perform corresponding program control on them. Only the users who have passed the authentication can obtain the unlocking authorization and thus correctly complete the unlocking operation.

[0053] Secondly, in order to further improve the security, the following program can also be set. Only when the lock beam mechanism 10 is in the unlocked state, the control module 22 can perform corresponding setting operations on the user authentication module, such as setting a preset password or inputting a preset fingerprint, etc. When the lock beam mechanism 10 is in the locked state, that is, after the lock column 11 of the lock beam mechanism 10 is locked by the locking tongue assembly 50, the control module 22 cannot perform setting operations on the user authentication module and can only perform corresponding authentication operations, that is, it can perform the unlocking operation of the lock beam mechanism 10. Thus, it is prevented that when the lock beam mechanism 10 is in the locked state, unauthorized personnel accidentally, unexpectedly or without authorization perform setting operations on the lock beam mechanism 10, resulting in errors or non-responses of the control module 22 of the locking mechanism 30.

[0054] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
