Description

Technical Field

[0001] This utility model relates to locks, specifically locks and handcuff locks. Background Technology

[0002] A handcuff lock is a type of lock that resembles a handcuff, consisting of a lock body and a lever. Currently, this type of lock requires manual rotation of the lever after unlocking. Users must hold the lock body with one hand and turn the key with the other, then rotate the lever after unlocking. This unlocking method is inconvenient and negatively impacts the user experience. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lock, a handcuff lock, which can improve the problem of inconvenient unlocking operation and improve the ease of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A lock includes a housing, an unlocking component and a locking component both disposed within the housing, and a fan beam movably connected to the housing. The unlocking component has a driving part corresponding to the position of the locking component, and the locking component has a groove corresponding to the position of the driving part. The two side walls of the groove cooperate with the driving part, and the movement of the driving part drives the locking component to a locked or unlocked position. The fan beam has a locking groove corresponding to the position of the locking component, used to cooperate with the insertion or removal of the locking component to lock or unlock the fan beam. The housing also has a slider and a first elastic element corresponding to the position of the fan beam. The slider is connected to the first elastic element, which maintains the tendency to push the fan beam outwards. The unlocking component is in a locked state when in the locked state, restricting the movement of the locking component. This design allows the fan beam to automatically pop out after unlocking, facilitating user use. The cooperation between the driving part and the groove allows the driving part to be bound to the locking component, and the movement of the driving part synchronously drives the movement of the locking component. Moreover, the unlocking component has a locking function in the locked state, and the movement of the locking component can be restricted by the driving part, resulting in higher security.

[0005] As a further improvement of this utility model, a guide protrusion is provided on the side of the locking member corresponding to one end of the locking groove, and a slide is provided on the housing corresponding to the position of the guide protrusion. The guide protrusion is located in the slide and moves in cooperation with the slide. The slide can cooperate with the guide protrusion to guide the movement of the locking member more stably.

[0006] As a further improvement of this utility model, there are two guide protrusions and two slides. The two guide protrusions are located on the corresponding sides of the locking member, and the two slides are located on the housing at the positions corresponding to the guide protrusions. The cooperation of the two guide protrusions and the slides can further stabilize the movement of the locking member and also help to maintain a stable fit between the locking member and the driving part.

[0007] As a further improvement of this utility model, a limiting protrusion is also provided on the housing, which is located on the other side of the lock groove corresponding to the fan beam. The limiting protrusion can restrict the deformation of the fan beam, increasing the difficulty for unauthorized personnel to pick the lock.

[0008] As a further improvement of this utility model, a second elastic element is also provided inside the housing. This second elastic element is connected to the locking element and provides a tendency for the locking element to move toward the locking groove. The second elastic element enables the locking element to maintain its movement tendency, making the fit between the groove and the driving part more stable, and making the movement of the locking element more stable.

[0009] As a further improvement of this invention, the slide rails on the housing are formed by stamping. This processing method is simple and has high production efficiency.

[0010] As a further improvement of this utility model, the limiting protrusion on the shell is formed by stamping. This processing method is simple and has high production efficiency.

[0011] As a further improvement of this utility model, the slider, after being pushed out of the fan beam by the first elastic element, is positioned at the corresponding locking member, restricting the locking member's movement toward the locked position. This design allows the slider to restrict the movement of the locking member. If the fan beam is not reinserted into the housing, the unlocking component cannot reset to allow the locking member to extend, preventing accidental operation that could cause the locking member to move to the locked position, affecting the insertion of the fan beam, or even causing the fan beam to collide with the locking member at the locked position during insertion, resulting in deformation of the locking member and preventing it from properly engaging with the lock groove for locking.

[0012] As a further improvement of this utility model, the size of the locking groove is larger than that of the locking member, and the locking member cooperates with the locking groove to form a margin for the movement of the fan beam. This margin allows the locking member to more easily enter the locking groove and lock itself, and by utilizing the cooperation of the first elastic member and the slider, the fan beam can be pushed outward by a certain stroke, so that the locking groove of the fan beam in the locked state can maintain a mating state with the locking member.

[0013] A handcuff lock is also provided, which employs the locking mechanism described in any of the above claims, wherein the fan beam is rotatably connected to the housing.

[0014] The beneficial effects of this utility model are that the lock, through the cooperation of the first elastic element and the slider, allows the fan beam to automatically pop out after unlocking, reducing the manual operation steps of the user and making it convenient for the user to use; the cooperation between the drive part and the groove allows the drive part to be bound to the locking part, and the movement of the locking part is synchronously driven by the movement of the drive part, and the unlocking part has a locking function in the locked state, which can restrict the movement of the locking part through the drive part, thus helping to improve security.

[0021] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figure 1-5 As shown, a lock according to this embodiment includes a housing 1, an unlocking component 2 and a locking component 3 both disposed within the housing 1, and a fan beam 4 movably connected to the housing 1. The unlocking component 2 has a driving part 21 at the position corresponding to the locking component 3, and the locking component 3 has a groove 31 at the position corresponding to the driving part 21. The two side walls of the groove 31 cooperate with the driving part 21, and the locking component 3 moves to the locked position or the unlocked position as the driving part 21 moves. The fan beam 4 has a lock groove 42 at the position corresponding to the locking component 3, which is used to cooperate with the insertion or removal of the locking component 3 to lock or unlock the fan beam 4. The housing 1 also has a slider 5 and a first elastic member 6 at the position corresponding to the fan beam 4. The slider 5 is connected to the first elastic member 6, and the first elastic member 6 maintains the tendency to push the fan beam 4 out. When the unlocking component 2 is in the locked state, it is in the locked state, restricting the movement of the locking component 3.

[0023] The housing 1 can be formed by two half-shells interlocking, creating an internal mounting cavity. The unlocking component 2 can be a mechanical lock cylinder, and the locking component 3 can be a columnar structure. When locking, the fan beam 4 is inserted into the housing 1, compressing the first elastic element 6. At this time, the unlocking component 2 is in the locked state, and the driving part 21 restricts the movement of the locking component 3, keeping it in the position inserted into the lock groove 42, thus forming a lock. When unlocking, the unlocking component 2 is operated to change it from the locked state to the unlocked state. The driving part 21 moves with the unlocking component 2, engaging with the side wall of the groove 31, causing the locking component 3 to leave the lock groove 42. At this time, the first elastic element 6 releases its elastic potential energy, pushing the slider 5. The slider 5 pushes the fan beam 4 outward, achieving automatic unlocking and ejection. This scheme, through the engagement of the driving part 21 and the groove 31, creates a linkage between the driving part 21 and the locking component 3. The unlocking component 2, in the locked state, indirectly restricts the movement of the locking component 3 by restricting the movement of the driving part 21, which helps improve the security and reliability of the lock. Simultaneously, the automatic ejection of the fan beam 4 using the first elastic element 6 improves operational convenience.

[0024] In order to facilitate the stable movement of the locking member 3, in one optional scheme, a guide protrusion 32 is provided on the side of the locking member 3 corresponding to one end of the locking groove 42, and a slide rail 11 is provided on the housing 1 corresponding to the position of the guide protrusion 32. The guide protrusion 32 is located in the slide rail 11 and moves in cooperation with the slide rail 11.

[0025] The guide protrusion 32 can be integrally formed with the locking member 3, and the slide 11 can be a recessed structure on the side wall of the housing 1. When the locking member 3 moves with the drive unit 21, the guide protrusion 32 slides along the slide 11, and the slide 11 provides lateral restraint to the guide protrusion 32, causing the locking member 3 to reciprocate along a predetermined trajectory, reducing offset or jamming. This solution, through the guiding cooperation between the guide protrusion 32 and the slide 11, can improve the stability and smoothness of the movement of the locking member 3, and reduce the risk of cooperation failure caused by the misalignment of the locking member 3.

[0026] Specifically, further optimization can be achieved by selecting the following method: there are two guide protrusions 32 and two slides 11. The two guide protrusions 32 are located on the two sides of the locking member 3 respectively, and the two slides 11 are located on the housing 1 at the positions corresponding to the guide protrusions 32.

[0027] Two guide protrusions 32 can be symmetrically arranged on both sides of the locking member 3, and two slides 11 are correspondingly opened on the two side walls or different positions on the same side wall of the housing 1. The double-sided guide structure can support and limit the locking member 3 from both sides simultaneously, so that the locking member 3 maintains better balance during reciprocating movement. By increasing the guide mating points, this solution can further improve the smoothness of the movement of the locking member 3 and help maintain a stable engagement relationship between the locking member 3 and the drive unit 21.

[0028] In some options, the housing 1 is also provided with a limiting protrusion 12, which is located on the other side of the locking groove 42 corresponding to the fan beam 4.

[0029] The limiting protrusion 12 is located on the side of the fan beam 4 opposite to the locking groove 42. When an external force attempts to pry the fan beam 4, the limiting protrusion 12 can abut against the side wall of the fan beam 4, restricting the deformation of the fan beam 4 away from the locking member 3, making it difficult for the fan beam 4 to disengage from the locking member 3. This design, by adding the limiting protrusion 12, can increase the deformation resistance of the fan beam 4 when illegally pried, thus helping to improve the anti-pry performance.

[0030] To further improve the stability of the engagement between the locking member 3 and the locking groove 42, a second elastic member 7 is also provided inside the housing 1. The second elastic member 7 is connected to the locking member 3 and provides a tendency for the locking member 3 to move toward the locking groove 42.

[0031] The second elastic element 7 can be a compression spring, with one end abutting against the internal structure of the housing 1 and the other end abutting against or hooking against the locking element 3. During locking, when the locking groove 42 of the fan beam 4 aligns with the locking element 3, the second elastic element 7 releases its stored energy to push the locking element 3 towards the locking groove 42, allowing the locking element 3 to automatically insert into the locking groove 42. After unlocking, the second elastic element 7 also keeps the locking element 3 tightly fitted against the side wall of the groove 31 of the drive unit 21, reducing gap wobble. This solution, by providing auxiliary pushing force through the second elastic element 7, can improve the automatic alignment performance of the locking element 3 and the locking groove 42, and help maintain a stable fit between the drive unit 21 and the groove 31.

[0032] In terms of processing and manufacturing, the slide rail 11 on the housing 1 is formed by stamping.

[0033] Accordingly, the limiting protrusion 12 on the housing 1 is formed by stamping.

[0034] Stamping is a simple process with low manufacturing costs. It can be used to stamp metal materials to form concave or convex structures, resulting in high production efficiency.

[0035] To avoid accidental operation, the slider 5 pushes the fan beam 4 out through the first elastic element 6 and is positioned at the corresponding locking element 3, restricting the locking element 3 from moving toward the locked position.

[0036] The slider 5 can be block-shaped and installed inside the housing 1 to abut against the end of the fan beam 4. The first elastic element 6 can be a compression spring, installed between the slider 5 and the internal structure of the housing 1. After unlocking, the first elastic element 6 pushes the slider 5 and the fan beam 4 outward. When the slider 5 is in position, it stops at the position aligned with the locking element 3. At this time, the side wall of the slider 5 interferes with the movement path of the locking element 3, preventing the locking element 3 from moving in the extension direction. If the user attempts to reset the unlocking component 2 without pressing the fan beam 4 back into the housing 1, the locking element 3 cannot enter the locked position due to the obstruction of the slider 5, thus avoiding the collision between the locking element 3 and the end of the fan beam 4. This scheme utilizes the occupant function of the slider 5 in the pop-out position, which can reduce the risk of parts collision caused by misoperation and help extend the service life of the locking element 3. When using a mechanical lock cylinder as the unlocking component 2, if the fan beam 4 is not reinserted into position, the unlocking component 2 cannot be reset and the key cannot be removed. Only after the fan beam 4 is reinserted into position can the unlocking component 2 be reset, locked, and the key removed.

[0037] In addition, the size of the locking groove 42 is larger than that of the locking member 3. The locking member 3 and the locking groove 42 cooperate to form a margin space for the fan beam 4 to move.

[0038] The length of the locking groove 42 is greater than the size of the locking member 3, allowing the fan beam 4 to slide relative to the locking member 3 within a certain range after the locking member 3 is inserted into the locking groove 42. During locking, even if there is a slight deviation in the insertion position of the fan beam 4, the extra space in the locking groove 42 can accommodate the insertion of the locking member 3. After locking, the first elastic member 6 continuously applies an outward pushing force to the fan beam 4 through the slider 5, keeping one side wall of the locking groove 42 of the fan beam 4 in contact with the locking member 3. Simultaneously, the extra space allows the fan beam 4 to move slightly outward under the action of the first elastic member 6, forming a stable abutment fit between the locking groove 42 and the locking member 3. This design, by setting a dimensional difference to create extra space, reduces the alignment accuracy requirements between the fan beam 4 and the locking member 3, helps improve locking smoothness, and utilizes the first elastic member 6 to maintain the abutment state, thus improving locking stability.

[0039] Based on the above lock structure, this embodiment also provides a handcuff lock, which adopts any of the locks described above, with the fan beam 4 rotatably connected to the housing 1.

[0040] One end of the fan beam 4 is rotatably connected to the housing 1 via a hinge, pin, or rivet, while the other end is a free end that can be rotatably inserted into the lock hole of the housing 1. When unlocking, the fan beam 4 automatically pops out under the action of the first elastic element 6 and flips outward around the rotatable connection end, allowing the user to detach it from the housing 1 without manually moving the fan beam 4. When locking, the free end of the fan beam 4 is aligned with the lock hole of the housing 1 and pressed in. The fan beam 4 rotates around the rotatable end, compressing the first elastic element 6 until the locking element 3 is inserted into the lock groove 42 to form a lock. This design combines an automatic pop-out structure with a rotatable connection, simplifying the unlocking operation of the handcuff lock and improving the user experience.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
