Description

Technical Field

[0001] This invention relates to the field of zippers, and more specifically to a zipper locking device and a zipper structure. Background Technology

[0002] Zippers, as a common connecting device, are widely used in clothing, bags, tents, and many other products. Traditional zippers typically consist of two strips with metal or plastic teeth; pulling a slider causes the two strips to interlock or separate, achieving the purpose of opening and closing. Although traditional zippers are relatively mature in design and use, some inconveniences and shortcomings still exist in practical applications.

[0003] First, during the use of traditional zippers, especially during the insertion process, the repeated friction between the positioning insert, the buckle, and the positioning stop is a major problem. This back-and-forth wear not only damages the positioning insert, the buckle, and the positioning stop, but also significantly reduces the overall lifespan of the zipper over time. This wear problem is particularly prominent in situations where zippers need to be used frequently, such as sportswear and outdoor equipment.

[0004] Secondly, a significant drawback of traditional zippers is that the positioning insert and the zipper connecting piece 100 are prone to tearing at the head connection point. This tearing is usually caused by repeated use, excessive force, or improper operation. Once a tear occurs, such as... Figure 7 As shown, once it tears, a tear C will be created, which will greatly reduce the overall structural integrity and functionality of the zipper, and sometimes even require complete replacement. This not only increases maintenance costs, but also affects the user experience.

[0005] In addition, traditional zippers have a significant inconvenience in actual operation. Because the positioning insert simply positions itself when inserted into the positioning stop, it has a degree of movement in the length direction without any limit. Therefore, during the pull-out and locking process, users often need to hold the positioning stop and the positioning insert with one hand to prevent them from separating during the pull-out process. This operation requires a high level of dexterity and may cause difficulties for users with weak hand dexterity or strength, and may even require multiple resets and restarts of the pull-out operation, which significantly affects the efficiency and comfort of use. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a zipper locking device and zipper structure that adopts a horizontal insertion method, changing the traditional interlocking method and effectively solving the shortcomings of the prior art.

[0007] This invention is achieved through the following technical solution: a zipper locking device, comprising:

[0008] A positioning stop is located at the very bottom of the zipper. The positioning stop includes a main body and a movable part. The movable part is located at the bottom of the main body and forms a space-adjustable first insertion cavity with the main body.

[0009] A buckle, installed on a zipper, the buckle includes a buckle body and a buckle movable part, the buckle movable part is located at the bottom of the buckle body, and the buckle body and the buckle movable part form a space-adjustable second insertion cavity;

[0010] The movable push-pull assembly is installed at the top of the latch and the positioning stop. The first insertion cavity and the second insertion cavity are opened by pressing the movable push-pull assembly, and the movable part of the latch is locked by pulling the movable push-pull assembly.

[0011] As a preferred technical solution, the main body of the latch is provided with a fixed connecting section in the middle. The fixed connecting section is provided with a movable assembly groove on one side of the movable part of the latch. The movable part of the latch is movably installed in the movable assembly groove. The movable part of the latch has a movable connecting section. The movable connecting section is inserted into the movable assembly cavity and forms a partition plate through the movable connecting section and the fixed connecting section.

[0012] As a preferred technical solution, the main body of the latch is provided with a first limiting stop on the side opposite to the movable part of the latch, and the movable part of the latch is provided with a second limiting stop on the side opposite to the main body of the latch, and the opposing surfaces of the first limiting stop and the second limiting stop form a first gap cavity.

[0013] As a preferred technical solution, the two sides of the main body of the stop are formed with downwardly extending third limiting edges, and the movable part of the stop is provided with a corresponding fourth limiting edge relative to the third limiting edge. The opposing surfaces of the third limiting edge and the fourth limiting edge form a second gap cavity, and the second gap cavity and the first gap cavity formed on both sides of the latch are connected to each other in the length direction.

[0014] As a preferred technical solution, the movable push-pull assembly includes a push-pull sleeve, a pull buckle is installed on the top of the push-pull sleeve, the push-pull sleeve is slidably installed on a first guide slide rod on the top of the buckle, and a second guide slide rod is provided on the top of the positioning stop opposite to the first guide slide rod;

[0015] The push-pull sleeve has a sliding push-pull cavity, which opens on the side opposite to the second guide slide rod. When the push-pull sleeve moves toward the second guide slide rod, the push-pull sleeve partially moves onto the second guide slide rod.

[0016] The first guide slide rod has a movable cavity, and the bottom surface of the movable cavity has multiple through holes. A first drive link is installed through each of the first through holes. One end of the first drive link extends into the movable cavity, and the other end passes through the first through hole and is fixedly connected to the upper end face of the latch movable part. Multiple sets of connecting springs are also provided between the top end face of the latch movable part and the latch body. The connecting springs are all installed in the spring mounting holes opened at the top of the latch movable part. One end of the connecting spring is fixedly connected to the top of the latch body, and the other end of the connecting spring is fixedly connected to the bottom surface of the spring mounting hole. The latch movable part and the latch body are connected by the connecting springs. When the spring is in an unstretched state, the gap of the second insertion cavity is minimized.

[0017] The movable cavity is also provided with a push-pull drive locking component. One end of the push-pull drive locking component is fixedly connected to the connecting end face of one side of the push-pull sleeve. The push-pull drive locking component drives the first drive linkage to press down or lock the first drive linkage. The connecting end face of the push-pull sleeve is also provided with a return spring. One end of the return spring is fixedly connected to the push-pull sleeve, and the other end is fixedly connected to the end face of the first guide slide rod.

[0018] As a preferred technical solution, the push-pull drive locking component includes a push-pull drive plate, a first drive pressing block, a locking hook, and a locking buckle. One end of the push-pull drive plate is fixedly connected to the connecting end face of the push-pull sleeve. The push-pull drive plate moves through the first guide slide rod and extends into the movable cavity. The first drive pressing block is fixedly installed at the bottom of the push-pull drive plate and away from the first drive connecting rod. The locking hook is set on the push-pull drive plate away from the first drive pressing block. The locking buckle is set on the side of the locking hook close to the first drive connecting rod. A locking hole is provided on the first drive connecting rod located at the closest end of the locking buckle.

[0019] When the push-pull drive plate is pushed, the first drive extrusion block contacts and extrudes the first drive linkage. At this time, the first drive linkage pushes out the bottom locking movable part, and the gap of the second insertion cavity gradually increases.

[0020] When the push-pull drive plate is pulled out, the latch engages into the lock hole. At this time, the movable part of the latch cannot move downward relative to the main body of the latch, which is used to lock the second insertion cavity.

[0021] As a preferred technical solution, a first inclined extrusion surface is formed on the lower end face of the first driving extrusion block, and a second inclined extrusion surface is formed on the top of the first driving connecting rod. When the first driving extrusion block contacts the second driving connecting rod, the first inclined extrusion surface contacts the second inclined extrusion surface.

[0022] As a preferred technical solution, a compression movable cavity is provided at the top of the stop body corresponding to the position of the second guide slide rod. The bottom surface of the compression movable cavity is provided with multiple second through holes. A second drive connecting rod is provided through each of the second through holes. One end of the second drive connecting rod extends into the compression movable cavity, and the other end of the second drive connecting rod passes through the through hole and is fixedly connected to the upper end face of the stop movable part. A second drive compression block is installed on the top of the compression movable cavity. The lower end face of the second drive compression block is fixedly connected to the top of the second drive connection. A support spring is fitted on each of the second drive connecting rods. The support spring pushes the second drive compression block upward and protrudes from the upper end face of the second guide slide rod.

[0023] The push-pull assembly has a third driving extrusion block at the opening of the push-pull sleeve. When the push-pull sleeve moves toward the second driving extrusion block, the third driving extrusion block and the second driving extrusion block press against each other, causing the second driving extrusion block to descend and expel the second driving link. At this time, the gap of the first insertion cavity gradually increases. The second driving extrusion block has a third inclined extrusion surface and a fourth inclined extrusion surface.

[0024] As a preferred technical solution, a first positioning post is provided on the side of the first insertion cavity, and a second positioning post is provided on the bottom surface of the second insertion cavity. A first positioning hole is provided on the positioning insert of the zipper corresponding to the position of the first positioning post, and a second positioning hole is provided on the position of the second positioning post. When the gap between the first insertion cavity and the second insertion cavity increases, the positioning insert of the zipper passes through the first gap cavity and the second gap cavity and is respectively inserted into the first insertion cavity and the second insertion cavity. At this time, the first positioning post is positioned and inserted into the first positioning hole, and the second positioning post is inserted into the second positioning hole.

[0025] The present invention provides a zipper structure, including a zipper body, wherein the zipper body includes the aforementioned zipper locking device.

[0026] The beneficial effects of this invention are as follows: The zipper of this invention, by setting a floating positioning stop and a latch, and through a push-pull movable component, opens the first and second gap cavities, thereby adjusting the size of the first and second insertion mouths. This allows the zipper's positioning insert to be inserted horizontally from one side, changing the traditional interlocking structure. It has the following advantages:

[0027] Because the zipper's positioning insert is inserted horizontally from one side, there is no interlocking link, which reduces friction between the positioning insert and the latch and positioning stop, increases service life, and reduces wear.

[0028] It has two insertion methods: you can use the interlocking method to lock the zipper, or you can use the flat insertion method to lock the zipper. This prevents the positioning insert and the zipper connecting piece from tearing at the head connection position due to frequent use of the interlocking method or frequent excessive force during interlocking.

[0029] Since the present invention can be inserted horizontally, it is simpler to operate. Because it can be inserted horizontally, after the positioning insert of the zipper is inserted horizontally, the first positioning post can be horizontally positioned and inserted into the first positioning hole for positioning. After the positioning insert of the zipper is moved horizontally and snapped into the first gap cavity and the second gap cavity, the movable push-pull assembly is released. At this time, the movable part of the positioning stop is reset, and the second positioning post can be inserted into the second positioning hole of the positioning insert.

[0030] Once the stop is reset, the zipper positioning insert is fully locked. This way, when we pull the zipper, the positioning insert will not separate from the stop. Therefore, when pulling the zipper, one hand does not need to hold the stop and the positioning insert, allowing the zipper to be pulled more smoothly and quickly. This makes it suitable for different users.

[0031] When the zipper pull is pulled, the first drive linkage can be locked by the latch, so that the latch's movable part cannot move, making the latch a fixed whole. During the zipper pulling process, it can be used as a normal latch to lock the zipper. Attached Figure Description

[0042] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0043] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0044] like Figure 1 and Figure 2 As shown, a zipper locking device of the present invention includes a positioning stop located at the bottom of the zipper. The positioning stop includes a stop body and a stop movable part. The stop movable part is located at the bottom of the stop body and forms a space-adjustable first insertion cavity with the stop movable part and the stop body.

[0045] It also includes a latch, which is installed on the zipper. The latch includes a latch body and a latch movable part. The latch movable part is located at the bottom of the latch body and forms a space-adjustable second insertion cavity with the latch body and the latch movable part. The zipper is closed by the latch. When closed, the latch can be pulled upward. The latch movable part can be opened relative to the latch body. Therefore, the internal space of the second insertion cavity is adjustable.

[0046] It also includes a movable push-pull assembly, installed at the top of the latch and the positioning stop. Pressing the movable push-pull assembly opens the first and second insertion chambers, while pulling the movable push-pull assembly locks the latch's movable part. During operation, simply squeezing the movable push-pull assembly relative to the latch and the positioning stop opens the first and second insertion chambers. Once the first and second insertion chambers are open, as... Figure 3 As shown, slide the positioning insert into the first and second insertion chambers, then release the movable push-pull assembly to lock the positioning insert. Then pull the lock upwards to close the zipper.

[0047] Among them, such as Figure 2 As shown, a fixed connecting section is provided in the middle of the main body of the latch. A movable assembly groove is provided on one side of the movable part of the latch, and the movable part of the latch is movably installed in the movable assembly groove. The movable part of the latch has a movable connecting section, which is inserted into the movable assembly cavity and forms a partition plate through the movable connecting section and the fixed connecting section. In order to increase the connection strength, a slider with a "T" shaped cross section can also be provided on the side of the movable connecting section opposite to the fixed connecting section in this embodiment. Then, a slide groove with a "T" shaped cross section is provided on the side of the movable assembly cavity, and the slider is inserted into the slide groove to increase the connection capability between the two.

[0048] Please continue reading. Figure 2 The main body of the latch is provided with a first limiting stop on the side opposite to the movable part of the latch, and the movable part of the latch is provided with a second limiting stop on the side opposite to the main body of the latch. The opposing surfaces of the first limiting stop and the second limiting stop form a first gap cavity h1.

[0049] The main body of the stop has downwardly extending third limiting edges on both sides. The movable part of the stop has a corresponding fourth limiting edge relative to the third limiting edge. The opposing surfaces of the third limiting edge and the fourth limiting edge form a second gap cavity h2. The second gap cavity and the first gap cavity formed on both sides of the buckle are connected to each other in the length direction. When the movable push-pull component is pressed, the distance between the first gap cavity and the second gap cavity can be increased. When it is large enough, the positioning insert of the zipper can be moved through the first gap cavity and the second gap cavity and finally snapped into the first insertion cavity and the second insertion cavity.

[0050] like Figure 4 As shown, the movable push-pull assembly includes a push-pull sleeve, a pull buckle is installed on the top of the push-pull sleeve, the push-pull sleeve is slidably installed on the first guide slide rod on the top of the buckle, and a second guide slide rod is provided on the top of the positioning stop opposite the first guide slide rod. When the push-pull sleeve is pushed, the push-pull sleeve can be pushed from the upper part of the first guide slide rod into the second guide slide rod.

[0051] Please continue reading. Figure 4 The push-pull sleeve has a sliding push-pull cavity, which opens on the side opposite to the second guide slide rod. When the push-pull sleeve moves toward the second guide slide rod, the push-pull sleeve partially moves onto the second guide slide rod.

[0052] Among them, such as Figure 4 and Figure 6 As shown, a movable cavity is provided inside the first guide slide rod. The bottom surface of the movable cavity is provided with multiple through holes. A first drive link is provided through each through hole. One end of the first drive link extends into the movable cavity, and the other end passes through the first through hole and is fixedly connected to the upper end face of the movable part of the latch. Multiple sets of connecting springs are also provided between the top end face of the movable part of the latch and the main body of the latch. The connecting springs are all provided in the spring mounting holes opened at the top of the movable part of the latch. One end of the connecting spring is fixedly connected to the top of the main body of the latch, and the other end of the connecting spring is fixedly connected to the bottom surface of the spring mounting hole. The movable part of the latch and the main body of the latch are connected by the connecting springs. When the spring is in an unstretched state, the gap of the second insertion cavity is the smallest, and it is in a normal locking state. When the push-pull drive locking component is pushed, the second insertion cavity opens, the first drive link pushes down, and the connecting spring is stretched. Therefore, when the push force on the movable push-pull component is removed, the first drive link is reset by the connecting spring, and then the movable part of the latch is reset.

[0053] Among them, such as Figure 6 As shown, a push-pull drive locking component is also provided inside the movable cavity. One end of the push-pull drive locking component is fixedly connected to the connecting end face on one side of the push-pull sleeve. The push-pull drive locking component drives the first drive linkage to press down or lock the first drive linkage. A return spring is also provided on the connecting end face of the push-pull sleeve. One end of the return spring is fixedly connected to the push-pull sleeve, and the other end is fixedly connected to the end face of the first guide slide rod. The return spring resets the entire push-pull sleeve. When the push-pull sleeve is compressed, the return spring is compressed. After the push-pull sleeve is released, the return spring can be used to reset the push-pull sleeve.

[0054] Please continue reading. Figure 6The push-pull drive locking component includes a push-pull drive plate, a first drive pressing block, a locking hook, and a locking buckle. One end of the push-pull drive plate is fixedly connected to the connecting end face of the push-pull sleeve. The push-pull drive plate moves through the first guide slide rod and extends into the movable cavity. The first drive pressing block is fixedly installed at the bottom of the push-pull drive plate and away from the first drive connecting rod. The locking hook is set on the push-pull drive plate away from the first drive pressing block. The locking buckle is set on the side of the locking hook close to the first drive connecting rod. A locking hole is provided on the first drive connecting rod located at the closest end of the locking buckle.

[0055] When the push-pull drive plate is pushed, the first drive extrusion block contacts and extrudes the first drive linkage. At this time, the first drive linkage pushes out the bottom locking movable part, and the gap of the second insertion cavity gradually increases.

[0056] When the push-pull drive plate is pulled out, the latch engages into the lock hole. At this time, the movable part of the latch cannot move downward relative to the main body of the latch, which is used to lock the second insertion cavity. At this time, the entire latch cannot be opened. Therefore, when the zipper needs to be pulled, simply pull the entire push-pull sleeve upward to allow the latch to engage into the lock hole. At this time, the movable part of the latch cannot be pushed downward, and the entire latch can become a whole.

[0057] The lower end face of the first driving extrusion block forms a first inclined extrusion surface, and the top of the first driving connecting rod forms a second inclined extrusion surface. When the first driving extrusion block contacts the second driving connecting rod, the first inclined extrusion surface contacts the second inclined extrusion surface, at which point the first driving connecting rod can be pushed down, thereby pushing out the locking movable part and opening the gap cavity.

[0058] A compression chamber is provided at the top of the main body of the stop corresponding to the position of the second guide slide rod. The bottom surface of the compression chamber is provided with multiple second through holes. A second drive link is provided through each of the second through holes. One end of the second drive link extends into the compression chamber, and the other end of the second drive link passes through the through hole and is fixedly connected to the upper end face of the stop. A second drive compression block is installed at the top of the compression chamber. The lower end face of the second drive compression block is fixedly connected to the top of the second drive link. A support spring is fitted on each of the second drive links. The support spring pushes the second drive compression block upward and protrudes from the upper end face of the second guide slide rod.

[0059] The push-pull assembly has a third driving compression block at the opening of the push-pull sleeve. When the push-pull sleeve moves toward the second driving compression block, the third driving compression block and the second driving compression block press against each other, causing the second driving compression block to descend and squeeze out the second driving link. At this time, the gap in the first insertion cavity gradually increases. The second driving compression block has a third inclined compression surface and a fourth inclined compression surface. When the push-pull sleeve is pushed and displaced to the position of the second driving compression block, the third driving compression block squeezes the second driving compression block. The second driving compression block descends and squeezes the support spring, causing the second driving link to push out and push out the bottom stop movable part, thereby realizing the opening and closing of the gap cavity.

[0060] like Figure 3 and Figure 5 As shown, a first positioning post is provided on the side of the first insertion cavity, and a second positioning post is provided on the bottom surface of the second insertion cavity. A first positioning hole is provided on the positioning insert of the zipper corresponding to the position of the first positioning post, and a second positioning hole is provided corresponding to the position of the second positioning post. When the gap between the first and second insertion cavities increases, the positioning insert of the zipper passes through the first and second gap cavities and is respectively inserted into the first and second insertion cavities. At this time, the first positioning post is positioned and inserted into the first positioning hole, and the second positioning post is inserted into the second positioning hole. To allow the positioning... The positioning pin is better inserted into the positioning hole. The opening of the positioning hole can be set as a flared opening for better positioning. After the gap cavity is opened, the positioning insert of the zipper is moved horizontally and inserted into the insertion mouth, so that the first positioning pin is engaged in the first positioning hole. Then, the push-pull sleeve is released, and the spring is used to reset. The moving part of the stop is reset upward, so that the second positioning pin is inserted into the second positioning hole, completing the limiting of multiple directions. In this way, when we pull the zipper pull, we do not need to pinch the positioning stop and the positioning insert with our hands. The positioning insert will not separate from the positioning stop, making the operation smoother and the bottom of the zipper will not open.

[0061] The present invention provides a zipper structure, including a zipper body, wherein the zipper body includes the aforementioned zipper locking device.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
