Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to lock structure, and a bag lock having a lock structure. Background Technology

[0002] In existing lock products, especially those used in luggage, cabinet doors, and furniture, the internal structure typically includes key components for locking and unlocking, such as steel balls and compression springs. The proper functioning of these components is crucial to the reliability and security of the lock.

[0003] Taking wine cabinets as an example, locks are usually installed between the cabinet door and the cabinet body. The opening part generally refers to the movable part, such as the cabinet door, box lid or drawer. Users open and close the cabinet by operating the opening part. The main body is the fixed part, such as the cabinet body, box or furniture frame, which usually serves as the mounting base for the lock.

[0004] Currently, most locks use a small-diameter, spherical steel ball design. While this design satisfies the lock's requirements for the steel ball's flexibility and versatility to some extent, it introduces several problems during actual assembly. Most existing locks directly abut the steel ball against the end face of the compression spring to fix its position and provide elastic support. However, due to the small diameter and spherical shape of the steel ball, the contact area between the ball and the compression spring is limited during assembly, resulting in low friction. This makes it easily susceptible to rolling or displacement from even slight external forces, leading to the ball falling out. Furthermore, this direct contact method makes it difficult to guarantee the positioning accuracy of the steel ball during assembly. Lacking an effective limiting structure, the steel ball easily deviates from its intended position during assembly, affecting not only the lock's assembly efficiency but also potentially causing some steel balls to malfunction, thus impacting the overall performance of the lock.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] In existing lock products, especially those used in luggage, cabinet doors, and furniture, the internal structure typically includes key components for locking and unlocking, such as steel balls and compression springs. The proper functioning of these components is crucial to the reliability and security of the lock.

[0042] Taking wine cabinets as an example, locks are usually installed between the cabinet door and the cabinet body. The opening part generally refers to the movable part, such as the cabinet door, box lid or drawer. Users open and close the cabinet by operating the opening part. The main body is the fixed part, such as the cabinet body, box or furniture frame, which usually serves as the mounting base for the lock.

[0043] Currently, most locks use a small-diameter, spherical steel ball design. While this design satisfies the lock's requirements for the steel ball's flexibility and versatility to some extent, it introduces several problems during actual assembly. Most existing locks directly abut the steel ball against the end face of the compression spring to fix its position and provide elastic support. However, due to the small diameter and spherical shape of the steel ball, the contact area between the ball and the compression spring is limited during assembly, resulting in low friction. This makes it easily susceptible to rolling or displacement from even slight external forces, leading to the ball falling out. Furthermore, this direct contact method makes it difficult to guarantee the positioning accuracy of the steel ball during assembly. Lacking an effective limiting structure, the steel ball easily deviates from its intended position during assembly, affecting not only the lock's assembly efficiency but also potentially causing some steel balls to malfunction, thus impacting the overall performance of the lock.

[0044] Therefore, such as Figures 1 to 4As shown, the lock structure proposed in this utility model includes a connecting block 100, a latch 210, and a telescopic assembly 300. The connecting block 100 is fixedly connected to one of the opening portion and the main body portion, the telescopic assembly 300 is mounted on the connecting block 100, and the latch 210 is rotatably connected to the other of the opening portion and the main body portion. Specifically, the latch 210 is provided with a lock hole 2101, the telescopic assembly 300 includes a compression spring 310 and a plug block 320, and the plug block 320 includes a positioning portion 321 and a mating portion 323. The positioning portion 321 is inserted into one end of the compression spring 310, and the other end of the compression spring 310 is fixedly connected to the connecting block 100 and can drive the mating portion 323 to protrude from the connecting block 100. When the latch 210 rotates to engage the connecting block 100, the mating portion 323 can extend into the lock hole 2101 to lock the opening portion. It should be noted that, in terms of the locking function, the compression spring 310 is connected to the positioning part 321 of the plug-in block 320, which can stably drive the mating part 323 to protrude from the connecting block 100. When the latch 210 rotates and engages with the connecting block 100, the mating part 323 can accurately extend into the lock hole 2101 to complete the locking, ensuring the reliability and stability of the lock's locking state. From the perspective of structural stability, the plug-in block 320 is provided with a positioning part 321 that engages with the compression spring 310, which solves the problems of difficult assembly and easy detachment of the plug-in block 320, while taking into account both ease of assembly and stability of use.

[0045] Refer to Figure 1 In some embodiments of this utility model, the connecting block 100 is provided with a mounting hole 101, and the compression spring 310 and the plug-in block 320 are both mounted in the mounting hole 101. A first limiting structure is provided between the connecting block 100 and the plug-in block 320 to prevent the plug-in block 320 from dislodging from the mounting hole 101. It should be noted that by limiting the axial displacement of the plug-in block 320 through the first limiting structure, the compression spring 310 is effectively prevented from deforming or dislodging under long-term use or external impact, ensuring the structural integrity of the telescopic assembly 300.

[0046] In some existing designs, the protruding channel of the steel ball is a trumpet-shaped structure to limit the distance of the steel ball's protrusion. However, the fit between the trumpet-shaped structure and the steel ball is highly demanding, and the steel ball's diameter is small. Manufacturing errors can occur, easily resulting in smaller steel balls falling off directly or larger steel balls failing to protrude, thus failing to achieve the locking effect of engaging with the lock hole 2101. In some embodiments of this utility model, such as... Figure 1As shown, the first limiting structure includes a limiting part 322 disposed on the plug-in block 320 and an annular blocking part 110 disposed on the connecting block 100. The limiting part 322 is located between the positioning part 321 and the mating part 323, and the annular blocking part 110 is disposed around the mating part 323, located on the path of the limiting part 322 moving outward. By physically blocking the excessive movement of the plug-in block 320, the loss of lock function due to component separation is avoided, while reducing the dependence on precision during assembly and improving production efficiency and product consistency. The limiting part 322 serves as the axial constraint point of the insertion block 320, while the annular blocking part 110 allows the mating part 323 to protrude and engage with the lock hole 2101 to achieve the locking function. Simultaneously, the limiting part 322 prevents the insertion block 320 from disengaging due to the spring force of the compression spring 310 or external force. This optimizes the overall movement trajectory of the telescopic component 300, ensuring that the mating part 323 can accurately extend into the lock hole 2101 to complete the locking action, thereby improving the reliability and smoothness of operation of the lock. Optionally, the side of the mating part 323 facing away from the positioning part 321 is a spherical structure, and the shape of the lock hole 2101 matches the spherical structure. Utilizing the spherical contact characteristics reduces the frictional resistance between the mating part 323 and the lock hole 2101, making the lock 210 rotate more smoothly. Meanwhile, the adaptive nature of the spherical structure enhances the fault tolerance during locking. Even if there is a slight angular deviation in the latch 210, it can still be effectively locked, improving the convenience of user operation and the environmental adaptability of the lock, and reducing the risk of failure due to mechanical tolerances.

[0047] Refer to Figure 1 In some embodiments of this utility model, a stop 400 is fixedly provided inside the mounting hole 101. The stop 400 abuts against the end of the compression spring 310 opposite to the insertion block 320 to prevent the compression spring 310 from coming out of the mounting hole 101. This restrains the position of the compression spring 310 and prevents it from shifting or coming out due to vibration or external force. The fixing method of the stop 400 enhances the installation stability of the spring. For example, reliable fixing of the stop 400 can be achieved by welding or bonding, reducing production costs and improving product maintainability. Furthermore, the stop 400 is recessed into the mounting hole 101, i.e., its bottom surface is higher than the bottom end of the mounting hole 101, or, referring to... Figure 3When reversed, the top surface of the stop block 400 is lower than the top of the mounting hole 101, which reduces the risk of the stop block 400 loosening due to contact force with other components when the connecting block 100 is in contact with them. For example, the connecting block 100 is fixedly connected to the opening part, and the main body is fixedly connected to the mating block 200. When the opening part moves to a position suitable for locking with the main body, the mating block 200 abuts against the connecting block 100, thereby fitting against the end of the mounting hole 101. Since the stop block 400 is hidden inside the mounting hole 101, no external force is applied to the stop block 400, preventing it from shifting. Furthermore, the latch 210 is rotatably mounted on the mating block 200. One of the mating block 200 and the connecting block 100 is provided with a positioning block 201, and the other is provided with a positioning groove 102. The positioning block 201 and the positioning groove 102 are inserted into each other. For example, refer to... Figure 1 The positioning block 201 is disposed on the mating block 200, and the positioning groove 102 is disposed on the connecting block 100. When the opening part moves to a position suitable for locking with the main body, the positioning block 201 and the positioning groove 102 engage to align the connecting block 100 and the mating block 200, facilitating the rotation of the latch 210 to lock the connecting block 100 and the mating block 200. In other embodiments, the latch 210 may also be directly rotatably mounted on the main body. When the opening part moves to a position suitable for locking with the main body, the latch 210 is rotated to lock the connecting block 100.

[0048] Optionally, the outer peripheral wall of the stop 400 is provided with friction texture. The stop 400 and the mounting hole 101 are interference-fitted, which significantly improves the connection strength and sealing performance between the stop 400 and the connecting block 100. It should be noted that the friction texture design increases the friction of the contact surface, preventing the stop 400 from loosening due to vibration, while the interference fit further strengthens the mechanical fixing effect, ensuring a stable state during long-term use, thereby extending the service life of the lock and improving security.

[0049] However, in some applications, even with the positioning part 321 inserted into the compression spring 310, the insertion block 320 may still occasionally shift laterally under the thrust of the compression spring 310, causing the mating part 323 to fail to accurately align with the lock hole 2101. For example, during assembly: when the compression spring 310 drives the insertion block 320 to move, the steel ball, lacking a guiding structure, may easily deviate from its central path and become stuck in the space between the annular blocking part 110 and the lock hole 2101, unable to enter the lock hole 2101. As another example, during use: frequent opening and closing causes the latch 210 to vibrate, and the mating part 323 of the insertion block 320 may easily dislodge from the lock hole 2101 due to the deflection caused by the thrust of the compression spring 310, causing the lock to unlock unexpectedly.

[0050] The aforementioned problems cause the mating part 323 to frequently fail to fit into the lock hole 2101 during the assembly or use of the lock, which seriously affects the reliability of the locking function and may even cause safety hazards.

[0051] Therefore, such as Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the positioning part 321 is replaced by a guide groove 324. The guide groove 324 is disposed at one end of the plug-in block 320 away from the mating part 323. The guide groove 324 is countersunk and its center line coincides with the center line of the plug-in block 320. One end of the compression spring 310 extends into the guide groove 324 and pushes against the groove wall of the guide groove 324 to drive the mating part 323 to move outward along the center line of the plug-in block 320. It should be noted that replacing the positioning part 321 of the plug-in block 320 with the guide groove 324, and making the guide groove 324 countersunk and its center line coincide with the center line of the plug-in block 320, fundamentally changes the force transmission method between the compression spring 310 and the plug-in block 320. On the one hand, the countersunk push groove 324 increases the contact area between the compression spring 310 and the insertion block 320, making the thrust of the compression spring 310 evenly distributed on the end face of the insertion block 320, avoiding the problem of force dispersion caused by the small contact area in the traditional direct contact of steel ball and spring. On the other hand, the design of the center line coincidence further ensures that the thrust of the compression spring 310 is strictly transmitted along the axial direction of the insertion block 320, eliminating the interference of lateral force on the movement trajectory of the mating part 323. This structure ensures that the mating part 323 always moves along a straight path under the action of the thrust of the compression spring 310, accurately entering the lock hole 2101, completely solving the problem of the mating part 323 failing to enter the position due to the skew of the thrust, and significantly improving the stability and consistency of the lock's locking function. Specifically, a tapered guide groove surface 3241 is provided in the push groove 324, further optimizing the contact method between the compression spring 310 and the push groove 324. It is easy to understand that the tapered guide groove surface 3241 guides the end of the compression spring 310 to gradually fit against the groove wall when it is inserted, reducing the problem of uneven local force on the compression spring 310 caused by the initial installation angle deviation. At the same time, the tapered structure further increases the contact area between the end of the compression spring 310 and the guide groove 324, making the force transmission more uniform and stable, and avoiding the lateral component force generated by the force concentration of the compression spring 310. As a result, this design allows the mating part 323 to move strictly along the central axis direction under the thrust of the compression spring 310. Even under high vibration or frequent operation conditions, the mating part 323 can still accurately enter the lock hole 2101, completely eliminating the risk of locking failure caused by the deviation or dispersion of the thrust, and significantly improving the long-term reliability of the lock.

[0052] Furthermore, in some embodiments of this utility model, the periphery of the limiting part 322 facing the mating part 323 is provided with a chamfered structure to abut against the periphery of the annular blocking part 110, significantly optimizing the movement stability of the plug block 320 under the thrust of the compression spring 310. It can be understood that the chamfered structure guides the limiting part 322 to make smooth contact with the annular blocking part 110, reducing jamming during assembly and making it easier for the plug block 320 to move along the central axis under the thrust of the compression spring 310. Simultaneously, the design of the annular blocking part 110 around the mating part 323 further constrains the lateral displacement of the plug block 320, ensuring that the mating part 323 is always aligned with the center path of the lock hole 2101. This structure effectively solves the problem of the mating part 323 failing to enter the lock due to lateral displacement, such as a steel ball. Even under conditions of assembly vibration or frequent opening and closing, the mating part 323 can still accurately enter the lock hole 2101, significantly improving the reliability of the lock's locking function.

[0053] The bag lock according to the present invention includes a lock structure according to the present invention, which solves the problem of locking failure caused by easy displacement of steel balls in traditional bag locks, significantly improving the security and durability of bags. The structure simplifies the assembly process of bag locks, reduces production costs, and improves the convenience of user operation by optimizing the locking mechanism, thus meeting the modern bag demand for lightweight and high reliability.

[0055] The cabinet door lock according to an embodiment of the present invention includes a lock structure according to an embodiment of the present invention.

This design enhances the vibration resistance and long-term reliability of the cabinet door lock, while simplifying the maintenance process. It is suitable for cabinet door scenarios with frequent opening and closing, improving the user experience and product security.
