Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of locks, in particular to a locking device and a lock. BACKGROUND

[0002] As an important device for ensuring the safety of articles, locks are widely used in various fields of society, such as doors and windows, luggage and mechanical equipment, etc. The locking device, as the core component of the lock, its structure design directly determines the performance and purpose of the lock.

[0003] At present, the existing locking devices on the market mainly include pin locking devices, leaf locking devices and edge column locking devices. The pin locking device is usually composed of a locking device shell, an inner core, pins, springs and a keyhole. When the key is inserted, the teeth push the pins upwards, align the interface between the pins and the contact surface of the locking device shell and the inner core, and the inner core can be rotated to unlock. The leaf locking device is usually composed of a leaf (spring leaf), a locking device slot, a spring and a key. The leaf replaces the pin as a locking element. When the key is inserted, the teeth push the leaf to translate, align the gap of all leaves with the shear line of the locking device, and the inner core can be rotated. The edge column locking device is usually composed of an edge column tenon, a leaf, a spring and a key (inner milled key). When the key is inserted, the leaf forms a specific gap due to the different heights of the teeth, and the edge column tenon falls into the gap to release the restriction of the locking device and realize rotation. The structure of the above-mentioned locking devices is relatively complex, mainly suitable for some scenes with high security requirements, such as doors and windows and valuable articles. However, for articles such as toys and wardrobes, the above-mentioned locking devices have relatively high use cost, and since they are usually in a relatively safe external environment (such as at home or carried on the body), they only need to prevent the locked articles from moving relatively to maintain a fixed locked state. Therefore, there is less demand for security and more demand for convenience and simplicity of the locking device.

[0051] As shown in Figures 1 to 18 The lock in the present application includes a first lock shell 41, a second lock shell 42 and a locking device as described below.

[0052] Referring to Figures 1 to 18 A locking device is inserted into the first lock shell 41 and the second lock shell 42 to limit the relative movement between the first lock shell 41 and the second lock shell 42, which includes:

[0053] A lock body 1 is provided with a limiting hole 11, a clamping block 12 located in the limiting hole 11 and a first locking protrusion to limit the relative rotation between the first lock shell 41 and the second lock shell 42;

[0054] A locking assembly 2 is provided with a clamping groove 211 and a second locking protrusion 221, and the locking assembly 2 is partially located in the limiting hole 11, and the locking assembly 2 moves between a locked position and an unlocked position;

[0055] When the locking assembly 2 is in the locked position, the clamping block 12 is inserted into the clamping groove 211, and the second locking protrusion 221 is used to clamp the first lock shell 41 to limit the locking device from being pulled out of the first lock shell 41 and the second lock shell 42;

[0056] When the locking assembly 2 is in the unlocking position, the clamping groove 211 is disengaged from the clamping block 12, the second locking protrusion 221 is used to detach from the first lock shell 41, and the second locking protrusion 221 is located in the initial position, so that the locking device can be pulled out of the first lock shell 41 and the second lock shell 42.

[0057] Through the above structure, a locking device with simple structure and convenient use is provided. When it is necessary to limit the relative movement between the first lock shell 41 and the second lock shell 42, the locking device is only needed to be inserted into the first lock shell 41 and the second lock shell 42, and the locking assembly 2 is moved to the locking position. At this time, the clamping block 12 on the lock body 1 is accurately inserted into the clamping groove 211 of the locking assembly 2, and the second locking protrusion 221 is clamped to the first lock shell 41, so as to limit the locking device from being pulled out of the first lock shell 41 and the second lock shell 42, thereby limiting the relative movement between the first lock shell 41 and the second lock shell 42. In addition, the first locking protrusion 16 also limits the relative rotation of the first lock shell 41 and the second lock shell 42, so as to form a reliable locking state, effectively prevent the locked object from being opened accidentally, and ensure the safety of the object. When it is necessary to unlock, the locking assembly 2 is moved to the unlocking position, so that the clamping groove 211 is disengaged from the clamping block 12, and the constraint between the locking assembly 2 and the lock body 1 is released. At the same time, the second locking protrusion 221 can be smoothly detached from the first lock shell 41, and is arranged corresponding to the first locking protrusion 16, so that the locking device can be pulled out of the first lock shell 41 and the second lock shell 42 to achieve quick unlocking. This design not only simplifies the operation process, but also makes the structure more stable, and further improves the user experience. For example, when the locking device of the present application is used to make the toy in a locked state, the toy can be effectively kept in a locked state, and the user only needs to perform a simple operation to unlock when it is necessary to unlock, so as to effectively balance the safety and convenience, and provide an effective solution for the use scene of this kind of demand.

[0058] Optionally, the clamping groove 211 is a non-circular clamping groove.

[0059] It should be understood that the second locking protrusion 221 corresponds to the first locking protrusion 16, which means that the second locking protrusion 221 is not limited in movement when the locking assembly 2 moves between the locked position and the unlocked position. For example, the first lock shell 41 and the second lock shell 42 are provided with a sliding groove that penetrates the first lock shell 41 and the second lock shell 42. When the second locking protrusion 221 is located in the sliding groove, the second locking protrusion 221 is in an initial position and is substantially in the same plane as the first locking protrusion 16. At this time, the second locking protrusion 221 does not limit the relative movement between the first lock shell 41 and the second lock shell 42, and the second locking protrusion 221 is clamped in the first lock shell 41. At this time, the second locking protrusion 221 and the first locking protrusion 16 are not in the same plane.

[0060] In this embodiment, the end edge of the locking assembly 2 away from the second locking protrusion 221 is recessed inward to form the clamping groove 211.

[0061] Through the above structure, the position and shape of the clamping groove 211 are matched with the stress direction of the locking assembly 2 and the structure of the clamping block 12 of the lock body 1. When the locking assembly 2 moves to the locked position, the clamping block 12 of the lock body 1 naturally falls into the recessed clamping groove 211. The geometric constraint of the edge recess makes the clamping block 12 and the clamping groove 211 more closely matched, effectively reducing the shaking of the locking assembly 2 in the locked state. The recessed clamping groove 211 uses the edge space at the end of the locking assembly 2, without the need to increase the radial or axial size of the locking device, thereby improving its application in small-sized locks.

[0062] It should be understood that the clamping groove 211 can also be located at other positions on the locking assembly 2, such as the middle part of the locking assembly 2, and the clamping block 12 corresponds to the clamping groove 211.

[0063] In this embodiment, the locking assembly 2 includes a locking piece 21 and a connecting piece 22, the connecting piece 22 is connected to the locking piece 21, and the second locking protrusion 221 is located on the end of the connecting piece 22 away from the locking piece 21.

[0064] Through the above structure, the locking assembly 2 is divided into two independent components, the locking piece 21 and the connecting piece 22, which can effectively reduce the manufacturing and maintenance costs through modular design, and provide more optimization space for safety, convenience and adaptability.

[0065] In the embodiment, the locking device further comprises an elastic member 3, the locking member 21 is provided with a receiving space 213, the elastic member 3 is located in the receiving space 213, and one end of the elastic member 3 is connected to the connecting member 22 and the other end is connected to the locking member 21, and the elastic member 3 drives the locking member 21 to have a movement trend of moving from the unlocking position to the locking position.

[0066] Through the above structure, the locking device has the functions of automatic reset and locking. For example, when the locking device is in the unlocking state, the locking member 21 is in the unlocking position. In this process, the elastic member 3 is deformed due to the action of the connecting member 22 and stores elastic potential energy. When the external force is removed, the elastic member 3 releases the elastic potential energy. Since one end of the elastic member 3 is connected to the connecting member 22 and the other end is connected to the locking member 21, the released force drives the locking member 21 to move towards the locking position, realizes automatic reset, and the elastic member 3 continuously provides a movement trend of the locking member 21 moving towards the locking position. Under normal circumstances, this movement trend enables the locking member 21 to stably remain in the locking position, thereby ensuring that the locking device is in the locking state and enhancing the security and reliability of the lock.

[0067] In the embodiment, the size and shape of the elastic member 3 correspond to the receiving space 213.

[0068] Through the above structure, it is ensured that the elastic member 3 always moves linearly along the axial direction during compression and reset, avoiding the problems of skewing, jamming caused by too large space or stress concentration caused by too small space. For example, a cylindrical spring matches a cylindrical receiving space 213, which can minimize radial deviation and ensure that the elastic force uniformly acts on the unlocking object. Moreover, by matching the size and shape of the receiving space 213 to the elastic member 3, it is also possible to effectively prevent external impurities such as dust from entering the receiving space 213, effectively avoiding the influence of external factors.

[0069] In the embodiment, the locking member 21 can move along the longitudinal axis of the limiting hole 11 between the locking position and the unlocking position.

[0070] Through the above structure, the longitudinal axis of the limiting hole 11 provides a clear and unique guide path for the horizontal movement of the locking member 21, and the locking member 21 can move along the longitudinal axis, which avoids unstable conditions such as deviation and shaking during movement. For example, in frequent locking and unlocking operations, the locking member 21 can always move along a fixed path, ensuring the stability and reliability of the locking device.

[0071] In the embodiment, the connecting member 22 and the locking member 21 can rotate around the longitudinal axis of the limiting hole 11 between the first position and the second position.

[0072] Through the arrangement of the above structure, the guiding and limiting functions of the locking assembly 2 during movement from the locked position to the unlocked position are further optimized, the safety, stability and operation precision of the locking device as a whole are improved, so that during the rotation of the locking assembly 2 around the longitudinal axis, the locking assembly 2 is provided with stable support and guidance by the limiting groove 223, and the locking assembly 2 can only rotate within the path specified by the limiting groove 223, avoiding shaking, deviation or jamming during rotation, ensuring smooth operation of the entire unlocking process. Such stability makes the wear between the components more uniform during long-term use, reducing damage caused by abnormal friction and collision, and prolonging the service life of the locking device.

[0073] It should be understood that when the connecting piece 22 and the locking piece 21 are in the first position, the second locking protrusion 221 is clamped in the first lock shell 41; when the connecting piece 22 and the locking piece 21 are in the second position, the second locking protrusion 221 is arranged corresponding to the first locking protrusion 16.

[0074] In this embodiment, the connecting piece 22 is provided with a limiting groove 223, which is used to allow the connecting piece 22 to rotate between the first position and the second position; the lock body 1 is provided with a limiting piece 13, which is inserted into the limiting groove 223, so that the connecting piece 22 is at least partially located in the limiting hole 11.

[0075] Through the arrangement of the above structure, the connecting piece 22 can be limited to rotate between the first position and the second position, which can precisely and effectively limit the movement of the locking assembly 2 between the locked position and the unlocked position. When the locking assembly 2 moves from the locked position to the unlocked position, the limiting piece 13 on the lock body 1 is inserted into the limiting groove 223, which defines a clear path and range for the movement of the locking assembly 2, ensuring its movement in the predetermined track and avoiding deviation, shaking or jamming during movement, thereby ensuring smooth operation of the locking and unlocking operation of the locking device.

[0076] Optionally, the limiting groove 223 has a length corresponding to the rotation from the first position to the second position.

[0077] In this embodiment, the limiting groove 223 is a fan-shaped groove, and the central angle of the fan-shaped groove is 30°-90°.

[0078] Through the arrangement of the above structure, a relatively reasonable rotation range is provided for user operation. If the angle is too small, the operation may be too fine, increasing the probability of user misoperation; if the angle is too large, the operation process may become cumbersome, prolonging the unlocking time. This angle range facilitates accurate control of the rotation of the locking assembly 2 by the user, without making the operation too complex, improving the user experience, and the shape of the fan-shaped groove conforms to the movement trajectory of the rotation of the locking assembly 2 around the shaft, thereby providing smooth guidance for the rotation of the locking assembly 2. During the rotation, the locking assembly 2 can naturally move along the arc of the fan-shaped groove, reducing the jamming and resistance, and making the unlocking and locking operation smoother.

[0079] Optionally, the central angle of the fan-shaped groove is 45°.

[0080] In this embodiment, the lock body 1 is provided with a socket 14, the socket 14 is communicated with the limiting groove 223, and the limiting piece 13 is detachably arranged in the socket 14; when the limiting piece 13 is located in the socket 14 and the end of the limiting piece 13 is inserted into the limiting groove 223, the connecting piece 22 is at least partially located in the limiting hole 11.

[0081] Through the arrangement of the above structure, the stable cooperation between the limiting piece 13 and the locking assembly 2 is ensured. During the movement of the locking assembly 2, the limiting piece 13 can always maintain a good contact and guiding relationship with the limiting groove 223, reducing the possibility of jamming or failure caused by shaking or deviation. Even during long-term use, the normal operation of the locking device can be ensured, improving the reliability and durability of the locking device, and when the limiting piece 13 is damaged, it can be easily replaced by being taken out of the socket 14, saving the use cost and facilitating the maintenance.

[0082] In this embodiment, the end of the connecting piece 22 away from the second locking protrusion 221 is a connecting end 222, the locking piece 21 is provided with a recess structure, the shape and size of the recess structure correspond to the connecting end 222, and the connecting end 222 is inserted into the recess structure.

[0083] By accurately corresponding the shape and size of the recess structure to the connecting end 222, the connecting end 222 can be tightly inserted into the recess structure, realizing seamless docking between the two. This precise fitting relationship reduces the gap at the connection site, avoiding the shaking or loosening of the connecting piece 22 during use, thereby ensuring the stability and reliability of the locking device during locking and unlocking. In addition, the recess structure can limit the movement of the connecting end 222 in the radial direction and provide stable support in the axial direction.

[0084] In this embodiment, the shape of the recess structure is non-circular.

[0085] Through the arrangement of the above structure, when the locking piece 21 rotates, the connecting piece 22 rotates together through the characteristics of the non-circular structure, which simplifies the structure of the locking device and facilitates the use of the user.

[0086] In the embodiment, the materials constituting the lock body 1 and the locking assembly 2 are non-metallic materials.

[0087] Through the arrangement of the above structure, the weight of the locking device is significantly reduced, the inertial force during movement or rotation is reduced, and the user operation such as key rotation, pushing and pulling is more convenient and smooth.

[0088] In the embodiment, the lock body is provided with a first lock hole 15, and the locking piece is provided with a second lock hole 212. The first lock hole 15 and the second lock hole 212 are correspondingly arranged, and the size and shape of the second lock hole 212 correspond to the unlocking object. The inner wall of the first lock hole 15 is not in contact with the unlocking object.

[0089] Through the arrangement of the above structure, the unlocking object only needs to cooperate with the second lock hole 212 to drive the locking piece 21 to act. The first lock hole 15 as a fixed positioning structure does not directly bear the insertion force or rotational force of the unlocking object, which not only ensures the relative positioning accuracy between the locking piece 21 and the lock body 1, but also avoids direct wear of the unlocking object on the lock body 1 during unlocking, thereby improving the overall structural stability and service life of the lock. At the same time, the specific size and shape design of the second lock hole 212 can match the specific unlocking object to form a unique unlocking logic, effectively enhancing the anti-misoperation performance and security level of the lock.

[0090] The above is one or more embodiments provided in combination with specific content, and it is not intended that the specific implementation of the present application is limited to these descriptions. Any approximation, similarity, or replacement based on the concept of the present application should be considered as the protection scope of the present application.
