Description
Technical Field
[0001] This application relates to the field of zippers, and particularly to a zipper lock. Background Art
[0002] In zipper products, the slider lock, as a common protection mechanism, is usually used to prevent the zipper from opening under unexpected circumstances. However, the existing slider lock designs are prone to jamming during long-term use, affecting the user experience and product reliability.
[0003] Traditional slider lock structures are usually relatively simple, lacking effective buffering and unlocking mechanisms. As a result, when the slider slides within the slider lock, it is susceptible to external forces or frequent use, leading to problems such as friction and jamming between the slider and the lock body. Especially when the zipper is subjected to a large pulling force or the slider is repeatedly pulled and closed, the slider is likely to get stuck in the lock body and cannot be smoothly unlocked or continue to slide. This jamming phenomenon not only affects the smoothness of user operation but may also cause the zipper to be damaged or detached, affecting the overall service life of the zipper.
[0004] Specifically, traditional slider locks lack design structures such as "fitting curved surfaces" and "ejecting curved surfaces", which results in a lack of flexible transition in the sliding between the slider and the lock body. Due to the absence of elastic adjustment and buffering structures, when a large external force is applied, the slider cannot smoothly disengage from the lock body through deformation or reaction force, thus getting stuck in the lock body. This problem not only affects the durability of the product and the user experience but may even render the zipper completely unusable in certain scenarios. Summary of the Utility Model

[0044] An embodiment of the present application provides a zipper lock, including:
[0045] A slider, on which there is a fitting curved surface;
[0046] A lock body, on which a sliding groove and an elastic block groove are formed. When the slider is fixed in the sliding groove, the zipper lock is in a locked state, and the length direction of the sliding groove is perpendicular to the length direction of the elastic block groove;
[0047] An elastic block, which is slidably connected in the elastic block groove, elastically connected to the lock body, and has an ejection curved surface that cooperates with the fitting curved surface. When the zipper lock is in the locked state, the elastic block generates elastic deformation in the length direction of the elastic block groove;
[0048] When the zipper lock is unlocked, the ejection surface presses against the fitting surface, and the elastic block drives the slider to pop out of the sliding groove. The zipper lock provided above effectively alleviates the phenomenon of the slider being stuck inside the lock by setting the fitting surface and the ejection surface and using the elastic deformation of the elastic block. When the zipper lock is in the locked state, the elastic block undergoes elastic deformation in the length direction of the sliding groove, enabling the slider to maintain a good fitting state with the lock body. At the same time, when unlocking, through the pressing action of the ejection surface, the elastic block can effectively drive the slider to pop out, ensuring the smoothness and reliability of the unlocking operation.
[0049] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0050] Please refer to Figures 1-14 , an embodiment of the present application provides a zipper lock 100, including a slider 1, a lock body 2, and an elastic block 3. The slider 1 has a fitting surface 121. The lock body 2 is provided with a sliding groove 21 and a spring block groove 22. When the slider 1 is fixed in the sliding groove 21, the zipper lock 100 is in the locked state. The length direction of the sliding groove 21 is perpendicular to the length direction of the spring block groove 22. The elastic block 3 is slidably connected in the spring block groove 22. The elastic block 3 is elastically connected to the lock body 2. The elastic block 3 has an ejection surface 321 that cooperates with the fitting surface 121. When the zipper lock 100 is in the locked state, the elastic block 3 undergoes elastic deformation in the length direction of the spring block groove 22. When the zipper lock 100 is unlocked, the ejection surface 321 presses against the fitting surface 121, and the elastic block 3 drives the slider 1 to pop out of the sliding groove 21.
[0051] Specifically, the slider 1 is a part of the zipper that the user manually operates. The fitting curved surface 121 provided thereon enables the slider 1 to precisely match the ejection curved surface 321 in the lock body 2 when locked, ensuring a stable locking effect in the locked state. Through the design of the fitting curved surface 121, the contact area between the slider 1 and the lock body 2 can be effectively increased, thereby reducing the possibility of the slider 1 loosening in the locked state and improving the reliability of the locking. At the same time, the fitting curved surface 121 helps to connect more smoothly with the subsequent unlocking action. The lock body 2 is the main structure of the zipper lock 100, wherein the sliding groove 21 is used to guide and limit the movement of the slider 1, ensuring that the slider 1 can only move on a specified path. The block groove 22 is the channel for the movement of the elastic block 3, ensuring that the elastic block 3 can slide and produce elastic deformation during the unlocking or locking process. The setting of the sliding groove 21 and the block groove 22 provides a clear movement path, avoids the slider 1 and the elastic block 3 from deflecting or irregular movement, and improves the precision of the overall structure and the stability of operation. At the same time, the vertical arrangement design of the sliding groove 21 and the elastic block groove 22 increases the sliding resistance when unlocking, making the unlocking action more secure. The elastic block 3 is a key component to realize the pop-up unlocking function of the zipper lock 100, and can generate sufficient reaction force through elastic deformation to pop the slider 1 out of the sliding groove 21. The elastic connection of the elastic block 3 ensures the firmness when the zipper lock 100 is locked, and can provide sufficient elastic force to quickly push the slider 1 away from the lock body when unlocking, so as to avoid the user from using too much force or getting stuck when unlocking, and improve the convenience and smoothness of operation. The ejection curved surface 321 is a structure for pushing the slider 1 out of the lock body 2. When the zipper lock 100 is unlocked, the ejection curved surface 321 and the fitting curved surface 121 of the slider 1 squeeze each other, forming a reaction force to push the slider 1 to pop out. The design of the ejection curved surface 321 can ensure that the slider 1 pops out more smoothly and powerfully when unlocking, reduce the possibility of the slider 1 getting stuck, extend the service life of the zipper lock 100, and improve the user experience. When the zipper lock 100 is locked, the elastic block 3 undergoes elastic deformation in the block groove 22, ensuring that the locking state between the slider 1 and the lock body 2 is tight and seamless. The elastic deformation enables the slider 1 to achieve a tighter locking effect not only through mechanical locking when locked, but also through elastic force, thereby improving the stability of the zipper lock 100 when subjected to external forces and preventing the zipper from being accidentally unlocked during high-intensity use. During the unlocking process, the ejection surface 321 interacts with the fitting surface 121, and the reaction force of the elastic block 3 pushes the slider 1 away from the lock body 2 to achieve unlocking. This design ensures the smoothness of the unlocking action and avoids the problem of easy jamming of the traditional zipper lock 100. At the same time, the reaction force of the ejection surface 321 can ensure that the slider 1 is quickly and effectively disengaged from the sliding groove 21 when the user operates it, thereby improving the user experience.
[0052] In a specific example, the slider 1 includes a gripping rod 11 and a locking portion 12 protruding from the gripping rod 11. The fitting curved surface 121 is located on the locking portion 12, and the locking portion 12 can be slidably connected to the sliding groove 21;
[0053] A locking block 4 is slidably connected to the lock body 2. The sliding direction of the locking block 4 is perpendicular to the sliding direction of the sliding groove 21, and a locking hole 122 corresponding to the locking block 4 is formed in the locking portion 12;
[0054] When the locking block 4 slides into the locking hole 122, the slider 1 is fixed in the lock body 2.
[0055] Specifically, the gripping lever 11 is the part that the user grasps with their fingers when operating the zipper lock 100. Its function is to provide a gripping and force - applying point for the user, thus facilitating the operation of opening and closing the zipper. The locking part 12 is the part that extends from the gripping lever 11 and is responsible for connecting and sliding with the sliding groove 21 of the lock body 2. The design of the locking part 12 enables the slider 1 to be inserted into the lock body 2 and at the same time form a tight mechanical fit with the sliding groove 21, thereby ensuring that the zipper lock 100 remains stable when locked. The division of labor between the gripping lever 11 and the locking part 12 is clear, which is convenient for the user to grip and operate, and can also ensure that the slider 1 is firmly connected to the lock body 2, enhancing the operability and safety of the lock. The fitting curved surface 121 is a special curved - surface design located on the locking part 12, and its function is to cooperate with the ejection curved surface 321 on the elastic block 3. Through the contact between the fitting curved surface 121 and the ejection curved surface 321, precise positioning and sliding effects are generated during the locking and unlocking processes. The locking part 12 can be slidably connected to the sliding groove 21, indicating that the slider 1 can slide along the sliding groove 21 of the lock body 2 within a certain range. This sliding connection provides a structural basis for unlocking and locking the lock, enabling the slider 1 to move smoothly when locking or unlocking. The designs of the fitting curved surface 121 and the sliding groove 21 ensure a smooth transition of the slider 1 during locking and unlocking, not only reducing the possibility of mechanical jamming, but also improving the reliability and service life of the zipper lock 100. The locking block 4 is a key component located inside the lock body 2 and can slide in a certain direction. The sliding direction of the locking block 4 is perpendicular to the direction of the sliding groove 21, which means that its movement intersects with the sliding direction of the slider 1. The perpendicular - sliding design of the locking block 4 helps to effectively lock or unlock the slider 1 when the slider 1 is within the sliding groove 21, fixing it in the desired position. The vertical - direction locking mechanism enhances the anti - slip effect of the structure and ensures that the slider 1 can be smoothly released when unlocking. The locking hole 122 provided on the locking part 12 is a hole used to match the locking block 4. The locking block 4 can slide into the locking hole 122 to complete the fixation of the slider 1. The cooperation between the locking hole 122 and the locking block 4 ensures that when the locking block 4 slides into place, the slider 1 can be firmly locked inside the lock body 2, preventing the slider 1 from accidentally detaching. This mechanical locking mechanism greatly improves the safety and stability of the zipper lock 100. When the locking block 4 slides into the locking hole 122, the slider 1 will be completely fixed inside the lock body 2 and be in the locked state. At this time, the slider 1 cannot continue to slide or detach, ensuring the locking function of the zipper. This design, through the precise cooperation between the locking block 4 and the locking hole 122, ensures that the zipper lock 100 can achieve a stable locking effect during use, is not only easy to operate, but also can avoid accidental loosening caused by vibration or external force.
[0056] In a specific example, a locking groove 23 is formed in the lock body 2, and the locking block 4 is slidably connected in the locking groove 23;
[0057] A return spring 5 is provided between the locking block 4 and the lock body 2, and the elastic direction of the return spring 5 is parallel to the length direction of the locking groove 23;
[0058] When the zipper lock 100 is unlocked, the return spring 5 is in a compressed state.
[0059] Specifically, the locking groove 23 is a long and narrow channel located inside the lock body 2 for accommodating and guiding the sliding of the locking block 4. The length and width of the locking groove 23 should be designed to fit the locking block 4 to ensure that the locking block 4 can slide smoothly in the groove. The sliding connection between the locking block 4 and the locking groove 23 means that the locking block 4 can move in a specific direction within the locking groove 23. The sliding connection is usually designed as a linear slide so that the locking block 4 can smoothly enter or exit the locking hole 122, thereby realizing the locking or unlocking of the slider 1. The precise fit between the locking groove 23 and the locking block 4 makes the operation of the zipper lock 100 smoother and reduces the occurrence of jamming. This sliding design provides a fixed movement track for the locking block 4 to ensure that the locking block 4 can enter or exit the locking hole 122 at the appropriate time, ensuring the reliability of locking and unlocking. The return spring 5 is an elastic element located between the locking block 4 and the lock body 2, and its function is to automatically reset the locking block 4 to its initial position after it slides. The design of the spring ensures that the locking block 4 can quickly return to the standby state after unlocking or locking operations and is ready for the next operation. This indicates that the force-receiving direction of the return spring 5 is consistent with the sliding direction of the locking block 4. That is to say, when the locking block 4 slides, the spring is compressed; when the locking block 4 disengages from the locking hole 122, the elastic force of the spring will push it back to its original position. The design of the return spring 5 ensures that the locking block 4 can quickly return to its initial position after unlocking and prepares for the next locking. The parallel design of the elasticity of the spring and the locking groove 23 makes the movement smoother, effectively avoiding the delayed reset after manual operation and improving the operation efficiency and comfort. During the unlocking process, the user applies an external force to slide the locking block 4 outside the locking hole 122 and simultaneously compresses the return spring 5. When the return spring 5 is compressed, the locking block 4 is at the other end of the locking groove 23 and is ready to quickly reset after the unlocking operation ends. The return spring 5 is in a compressed state during the unlocking process and can provide sufficient elastic force to ensure that the locking block 4 quickly rebounds to its initial position after the external force is released. This design not only reduces the operation steps after unlocking but also ensures that the locking block 4 will not get stuck in the middle position, thereby increasing the reliability of the entire device.
[0060] In a specific example, a switch groove 24 is provided on the lock body 2, and the length direction of the switch groove 24 is parallel to the length direction of the locking groove 23. One side of the switch groove 24 is communicated with the locking groove 23, and the other side of the switch groove 24 is communicated with the outside;
[0061] A switch slider 6 is provided on the locking block 4, and the switch slider 6 is slidably connected to the switch groove 24.
[0062] Specifically, the switch groove 24 is a groove on the lock body 2, and its length direction is parallel to the length direction of the locking groove 23. This means that both extend along the same straight line direction, ensuring the coordinated movement between the switch slider 6 and the locking block 4. The design of the switch groove 24 being parallel to the locking groove 23 enables the switch slider 6 and the locking block 4 to perform sliding operations on the same plane, ensuring that the entire locking system has a compact structure and consistent movement trajectories. With the design of the switch groove 24 parallel to the locking groove 23, the operation of the entire device is smoother and more linear, avoiding complex sliding paths and making the connection between the switch slider 6 and the locking block 4 more stable. This design simplifies the mechanical structure and also improves the durability of the device. One side of the switch groove 24 is directly connected to the locking groove 23, ensuring the interaction between the locking block 4 and the switch slider 6. When the locking block 4 slides, it can interact with the outside world through the switch groove 24 to complete the locking or unlocking operation. The other side of the switch groove 24 is connected to the outside world, meaning that the switch slider 6 can slide under the action of an external force, thereby pushing the locking block 4 to move. Through external operations, the user can control the sliding of the locking block 4, and thus achieve the locking or unlocking of the slider 1. The connection of the switch groove 24 to the outside world enables the user to directly control the movement of the locking block 4 by sliding the switch slider 6 externally, simplifying the operation process of the lock. At the same time, the design of the switch groove 24 being connected to the locking groove 23 ensures that the movement of the switch slider 6 can directly affect the locking block 4, making the reaction of the entire device more sensitive and rapid. The switch slider 6 is an operating component located on the locking block 4, mainly used for the user to control the sliding of the locking block 4. By sliding the switch slider 6, the user can move the locking block 4 within the locking groove 23 to achieve the locking or unlocking operation. There is a sliding connection between the switch slider 6 and the switch groove 24, ensuring that the switch slider 6 can slide linearly along the switch groove 24. When an external force is applied by the user, the switch slider 6 pushes the locking block 4 to slide and is reset by the return spring 5 after the unlocking or locking operation is completed. The addition of the switch slider 6 provides an intuitive operation interface for the user, making the operation of the lock more convenient. By sliding the switch slider 6, the user can precisely control the movement of the locking block 4, thereby ensuring the accuracy of the locking or unlocking operation. The design of the sliding connection ensures the smoothness and flexibility of the movement, avoiding jamming caused by friction or resistance.
[0063] In a specific example, the switch slider 6 is bolted to the locking block 4.
[0064] Specifically, the bolt connection means that the switch slider 6 and the locking block 4 are connected together by bolts. This means that the switch slider 6 is fixed to the locking block 4 by bolts. When the user pushes or pulls the switch slider 6, the switch slider 6 will drive the locking block 4 to move together, realizing the control of the sliding of the locking block 4. The bolt passes through the holes of the switch slider 6 and the locking block 4, and the two are firmly connected together by tightening the nut or the bolt itself. This connection method ensures a firm connection between the switch slider 6 and the locking block 4, avoids the separation of the slider and the locking block 4 during operation, and ensures that the movement of the slider can be effectively transmitted to the locking block 4 to make it slide smoothly. The bolt connection provides high mechanical strength and can withstand a certain amount of external force, ensuring that the switch slider 6 and the locking block 4 will not loosen or fall off during long-term use. This high-strength connection method is especially suitable for lock structures that require frequent operation, which can effectively improve the durability and service life of the lock. Another advantage of the bolt connection is that it is convenient for disassembly and maintenance. The user can loosen the bolts as needed to replace or repair the components. This flexibility enhances the maintenance convenience of the lock. Once a component has a problem, the bolt connection can easily disassemble the switch slider 6 and the locking block 4, facilitating repair and replacement of components, and reducing the maintenance cost of the entire device. When the user slides the switch slider 6, the switch slider 6 is firmly connected to the locking block 4 by bolts, and the locking block 4 will slide in the locking groove 23 following the movement of the slider. The sliding direction of the switch slider 6 is the same as that of the locking block 4. Through the transmission of the bolt, the synchronous movement of the slider and the locking block 4 is ensured. During the unlocking operation, the user pushes the switch slider 6 to disengage the locking block 4 from the locking hole 122 to achieve unlocking; while during locking, the switch slider 6 drives the locking block 4 into the locking hole 122 to achieve locking.
[0065] In a specific example, a plurality of anti-slip protrusions 61 are provided on the side of the switch slider 6 close to the outside, and the anti-slip protrusions 61 are arranged at intervals on the switch slider 6.
[0066] Specifically, the switch slider 6 is provided with a plurality of anti-slip protrusions 61. The main function of these protrusions is to increase the surface friction and prevent the fingers from slipping during user operation. When the user pushes or pulls the switch slider 6, the fingers will come into contact with these protrusions. By increasing the friction, the user can better control the sliding of the slider. This design reduces the risk of operation errors caused by poor sliding or slipping. Especially when the fingers are wet, greasy or the environment is slippery, the anti-slip protrusions 61 can greatly improve the operation accuracy and comfort. The protrusions are arranged at intervals. This design helps to ensure the anti-slip function while avoiding the surface from being too rough and keeping the operation feel comfortable. The intervals between the protrusions enable the user to feel different levels on the surface of the slider during operation, which is beneficial for better holding the slider, and at the same time does not affect the overall aesthetics and feel of the slider. This interval design avoids the discomfort caused by overly dense protrusions on the slider surface and can, to a certain extent, reduce the weight of the slider and enhance the feel experience of the user during operation. The anti-slip protrusions 61 of the switch slider 6 are arranged on the side close to the outside. This means that these protrusions are the parts directly contacted by the fingers during user operation. This layout design is reasonable, and the position of the protrusions is just consistent with the finger contact area, thus maximizing its anti-slip effect and ensuring that the pushing and pulling operations of the slider can be more smooth. The anti-slip protrusions 61 close to the outside facilitate the user to quickly and accurately find the operation part of the slider without having to search or adjust the hand posture too much, thus improving the operation efficiency and convenience. Usually, the anti-slip protrusions 61 can be designed in different shapes and sizes to meet different design requirements. For example, the protrusions can be circular, square or strip-shaped, and the size and height can also be adjusted according to specific requirements. This flexible design can be customized according to the user's feel requirements and aesthetic considerations, so that the slider meets the ergonomic design while ensuring the function, and improves the use comfort. When the user needs to operate the lock, the switch slider 6 is pushed or pulled to lock or unlock. When the fingers move on the surface of the slider, the anti-slip protrusions 61 enhance the friction between the fingers and the slider, enabling the user to more stably control the sliding direction of the slider. Whether the user is pushing or pulling the slider, due to the existence of the anti-slip protrusions 61, even in the case of wet hands or sweating, the fingers can be prevented from slipping, thus successfully completing the operation.
[0067] In a specific example, the elastic block 3 includes a contact portion 32 and an elastic portion 31 provided on the contact portion 32. The length direction of the elastic portion 31 is parallel to the length direction of the elastic block groove 22, and the ejection curved surface 321 is located on the contact portion 32.
[0068] Specifically, the contact portion 32 is a main part of the elastic block 3 and directly contacts other components within the lock body (such as the sliding groove 21 and the ejector block groove 22). The design of the contact portion 32 ensures that the elastic block 3 can be correctly embedded and stabilized within the ejector block groove 22. The elastic portion 31 is a part of the elastic portion provided on the contact portion 32, and its main function is to provide the ability of elastic deformation. The design of the elastic portion 31 enables the elastic block 3 to deform when an external force is applied, thereby achieving a predetermined function. The ejection curved surface 321 is a special structure located on the contact portion 32. It is a surface of the elastic block 3, and by cooperating with the fitting curved surface 121 on the pull tab 1, it realizes the function of pushing or ejecting. The length direction of the elastic portion 31 is parallel to the length direction of the ejector block groove 22. This setting ensures that the elastic deformation of the elastic portion 31 within the ejector block groove 22 can occur along the axial direction consistent with the sliding direction, providing a stable and consistent elastic response. When an external force (such as the pulling force of the zipper) is applied, the elastic portion 31 can be compressed or extended along the axis parallel to its length direction, so that the elastic block 3 can effectively buffer the force transmission and achieve the required elastic rebound or pushing effect. The ejection curved surface 321 is located on the contact portion 32 of the elastic block 3. This means that on the outer side of the elastic block 3, where it directly contacts other components within the lock body (such as the fitting curved surface 121 of the pull tab 1). When the zipper lock 100 is in the locked state, the elastic deformation of the elastic portion 31 will cause the ejection curved surface 321 to squeeze the fitting curved surface 121 on the pull tab 1. This process can push the pull tab 1 out of the sliding groove 21 of the lock body, realizing the unlocking operation. The contact between the ejection curved surface 321 and the fitting curved surface 121, through elastic deformation and the cooperation of the curved surfaces, can buffer the direct transmission of external forces, reduce mechanical friction and jamming phenomena, thereby improving the smoothness and reliability of unlocking. In the locked state, the length direction of the elastic portion 31 is parallel to the length direction of the ejector block groove 22, ensuring that the elastic portion 31 can effectively perform elastic deformation within the ejector block groove 22. The ejection curved surface 321 contacts the fitting curved surface 121, keeping the pull tab 1 fixed within the lock body.
[0069] In a specific example, the gripping rod 11 includes a first section 111 and a second section 112. One end of the first section 111 is provided on the locking portion 12, and the other end of the first section 111 is provided on one end of the second section 112. In the first case, the included angle a between the length direction of the first section 111 and the length direction of the second section 112 satisfies the relation: 15° < a < 25°.
[0070] Specifically, the first section 111 is set on the locking part 12 and is the part connected to the core part of the slider 1. It is mainly used to transmit the pulling force to the locking part 12 when an external force is applied by the user. By setting the length and position of the first section 111, the force on the gripping rod 11 is ensured to be evenly distributed, so that the user can operate when locking or unlocking. The design of the first section 111 makes the structure of the gripping rod 11 more stable and not easily broken or deformed due to excessive pulling force. The second section 112 is another part of the gripping rod 11 and is usually located at the part held by the user's hand. This section can be designed and optimized according to the actual operating habits of the user. The existence of the second section 112 provides more areas for grasping, enabling the user to apply more control force, thereby improving the comfort and efficiency of the operation. The design of the included angle a is the core innovation of this structure. By controlling the included angle between the first section 111 and the second section 112 to be between 15° and 25°, the geometric structure of the gripping rod 11 can be effectively optimized to provide an ergonomic operating experience. The included angle range of 15° to 25° enables the gripping rod 11 to provide sufficient traction for unlocking operations at different angles, and can reduce the operating burden on the user when in the locked state. In addition, this angle design can maintain its stability when a greater external force is applied to the grip, and it is not easy to slip or deform.
[0071] In a specific example, in the second case, the length direction of the first section 111 is parallel to the length direction of the second section 112.
[0072] Specifically, when the length directions of the first section 111 and the second section 112 are parallel, the gripping rod 11 forms a straight-line structure. This structure has high stability during the force transmission process. Especially when the pulling force on the zipper increases, it can effectively prevent the gripping rod 11 from bending or twisting. The design of parallel lines can ensure that the gripping rod 11 can withstand greater external forces while keeping its deformation minimal. In this parallel state, the pulling force applied by the user can be transmitted more directly to the locking part 12, without consuming through bending or angle conversion. Therefore, the force transmission efficiency is higher, which can effectively reduce the unnecessary operating torque due to the angle, making it easier for the user to apply sufficient pulling force during the operation process, especially during unlocking or tightening, and reducing the unnecessary operating torque. In the series structure, the gripping rod 11 is suitable for scenarios where the user hopes to quickly and directly unlock or tighten, especially when no complex mechanical conversion is required. Compared with the structure with an included angle design in the first case, the parallel design is more suitable for the operation requirements of quick straight-line pulling or in a more compact space. The straight-line design of the gripping rod 11 provides the user with a more straightforward and direct operation method. This design can enable the slider 1 to slide smoothly within the lock body 2, without bringing additional friction or resistance due to angle changes, thereby reducing the hand fatigue of the user during long-term use.
[0073] In a specific example, the gripping lever 11 and the locking portion 12 are integrally formed.
[0074] Specifically, integrally formed means that in the production process, multiple components or structures are integrated into one whole through a one-step forming process, avoiding subsequent assembly or connection steps. The gripping lever 11 is part of the slider 1, the area that the user holds with their hand during operation, and is usually designed in an ergonomic shape to ensure comfortable operation. It is part of the slider 1 and cooperates with the sliding groove 21 or the locking block 4 in the lock body to achieve the locking function of the zipper. The integral formation of the gripping lever 11 and the locking portion 12 means that they are a continuous structure in design without an intermediate interface. This design can make the entire slider 1 more stable during use and reduce potential connection failures. It is usually formed using plastic, metal, or composite materials. The material selection depends on the durability requirements of the product and the manufacturing process. A common integrally formed method, especially suitable for plastic components. Molten plastic is injected into the mold through an injection mold, and an integrally formed component is obtained after cooling. For example, die casting is suitable for metal materials. Molten metal is injected into the mold through a die casting mold, and an integrated component is formed after cooling. Extrusion molding is used for the manufacture of some long or continuous profiles, and the material is extruded through the mold to obtain the desired shape.
[0075] The above are only the implementation manners of the present application. It should be noted here that for those of ordinary skill in the art, without departing from the creative concept of the present application, improvements can still be made, but these all fall within the protection scope of the present application.
