Technical Field
[0001] This utility model relates to the field of zipper technology, specifically to a metal-tooth-like zipper with a self-locking structure. Background Technology
[0002] Zippers offer an efficient way to connect and disconnect clothing. Traditional buttons require each buttonhole to be threaded through to secure clothing, a relatively cumbersome process, especially when dressing hastily or when clothing has many buttons. Zippers, on the other hand, allow for quick opening and closing of clothing simply by pulling the zipper pull. In many applications, preventing zippers from accidentally opening is crucial. In outdoor gear such as backpacks and tents, backpacks contain various essential items like food, warm clothing, and first-aid supplies. If the zipper lacks a self-locking mechanism, it may accidentally open due to shaking, impact, or snagging on branches during climbing, trekking through jungles, or in inclement weather, leading to the loss of equipment.
[0003] Chinese Utility Model Patent Publication No. CN 219613227 U discloses a multi-faceted toothed metal zipper. This zipper, through the installation of teeth A, teeth B, and protrusions, allows teeth A to enter the inner side of teeth B outside the chain belt A when the zipper head moves, resulting in close contact between teeth A and B. Simultaneously, the protrusions on the surfaces of teeth A and B increase the friction between them, thereby improving the zipper's lifespan. However, this multi-faceted toothed metal zipper does not automatically lock when closed, making it prone to accidental opening due to shaking, collisions, or external pulling. It also lacks manual locking, hindering users from selecting different locking methods for different usage scenarios, resulting in poor practicality. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a metal tooth zipper with a self-locking structure. It can effectively solve the problems in the prior art where when the zipper is closed, it is not easy for the two to lock automatically, and the zipper is easy to be accidentally opened due to shaking, collision or external pulling of the object. At the same time, it is not easy to lock manually, so it is not convenient for users to choose different locking methods according to different usage scenarios, resulting in poor practicality.
[0005] The technical solution adopted by this utility model is: a metal-tooth zipper with a self-locking structure, including a chain belt and a locking component. A chain is fixedly installed on the outer surface of the chain belt, a zipper head is provided on the outer surface of the chain, a stop block is fixedly installed on the outer surface of the zipper head, a first pull ring and a second pull ring are provided on the inner surface of the zipper head, a limit block is fixedly installed on the other end of the second pull ring away from the zipper head, a limit component is fixedly installed on the outer surface of the limit block, a slot one and a slot two are opened on the outer surface of the limit block, and a magnetic block one is fixedly installed on the inner surface of the limit block.
[0006] Preferably, the first pull ring and the second pull ring are located on the same horizontal plane, and the first pull ring and the second pull ring are located on both sides of the stop block.
[0007] The above technical solution, with pull rings located on the same horizontal plane and distributed on both sides of the stop, provides users with more diverse operating options, allowing them to flexibly select pull rings according to different usage scenarios and personal operating habits, thus improving the convenience and comfort of operation.
[0008] Preferably, there are two identical zipper heads, first pull rings, second pull rings, limiting blocks, and magnetic blocks. The two zipper heads, first pull rings, second pull rings, and limiting blocks have the same structure, and the two magnetic blocks are magnetically connected.
[0009] With the above technical solution, when the locking component is not used, the design of two magnetic blocks can automatically lock the zipper head when the zipper is closed by magnetically connecting the two, which can prevent the zipper from opening accidentally due to shaking, collision or other external forces. This improves the safety and stability of the zipper and is especially suitable for occasions where the zipper closure requirements are high, such as outdoor backpacks and sports equipment, to prevent items from falling and being lost.
[0010] Preferably, the limiting component includes a limiting box, a limiting frame is fixedly installed on the inner surface of the limiting box, a top cover is fixedly installed on the top of the limiting box, a spring is fixedly installed on the outer surface of the limiting frame, and a limiting post, a pull rod and a pull hook are fixedly installed on the other end of the spring away from the limiting frame. The limiting component is adapted to the locking component through the limiting post, and the limiting post passes through the limiting block and extends into the interior of the slot one.
[0011] Using the above technical solution, the zipper is pulled to the closed position, bringing the limiting blocks on the two zipper heads closer together. Then, the locking component's pin is aligned with slot one on the limiting block and gently inserted. During insertion, the pin presses against the limiting pin, compressing the spring. Once the pin is fully inserted into slot one, the limiting pin, under the spring's elasticity, engages in the positioning groove on the pin, achieving locking. To unlock, pull the lever; the lever will disengage the limiting pin from the positioning groove, and then the pin can be pulled out of slot one. The action of the spring and the limiting pin ensures a secure lock, effectively preventing the zipper from accidentally opening under external force.
[0012] Preferably, a sliding groove is formed through the outer surface of the top cover, and the sliding groove is slidably connected to the pull rod.
[0013] Through the above technical solution, the sliding connection design of the groove on the top cover and the pull rod provides a convenient way to unlock the device. Users can easily find the operating position of the pull rod through the groove, and when the pull rod is pulled, the groove can play a guiding and limiting role, making the movement of the pull rod more stable and accurate, and avoiding unlocking difficulties caused by the pull rod shaking or deviating from the direction.
[0014] Preferably, the locking assembly includes a locking frame and a plug, wherein the outer surface of the plug is provided with a positioning groove and a second magnetic block, and the second magnetic block is magnetically connected to the first magnetic block.
[0015] Through the above technical solution, during the insertion process, the second magnetic block will attract the first magnetic block, further assisting in positioning and fixing the position of the insertion post. Combined with the magnetic attraction connection between the first and second magnetic blocks, the stability is further enhanced.
[0016] Preferably, the outer surface of the locking frame is fixedly installed with a plug and a post, the plug and slot two are plugged in, and the post and slot one are plugged in.
[0017] With the above technical solution, after the zipper is closed, the insert on the locking frame is aligned with slot two on the limiting block, and the insert post is aligned with slot one. Then the locking frame is pushed towards the limiting block so that the insert is inserted into slot two and the insert post is inserted into slot one. The insertion and installation method of the insert and the insert post can limit the zipper head from multiple directions to prevent it from moving and coming off.
[0018] Compared with the prior art, this utility model provides a metal-tooth-like zipper with a self-locking structure, which has the following beneficial effects:
[0019] 1. This metal-tooth zipper with a self-locking structure has a first and a second pull ring at the same level and distributed on both sides of the stop block. Users can choose the pull ring according to their personal habits and ease of operation. Whether operating with one hand or two hands, it is easy to find the point of leverage, which improves the efficiency of opening and closing the zipper. The symmetrical arrangement of the two zipper heads and their related components, together with the magnetic connection of the first magnetic block, can automatically lock the zipper head when the zipper is closed, preventing the zipper from being accidentally opened due to shaking, collision or external pulling of the item. It is suitable for various occasions where the zipper needs to be kept closed.
[0020] 2. This metal-tooth zipper with a self-locking structure, featuring a combination of limiting and locking components, provides a reliable manual locking mechanism. The spring and limiting post ensure a secure lock, keeping the zipper closed even under significant external force. The sliding connection between the top cover's groove and the pull rod provides a convenient and intuitive unlocking method. Guided by the groove, the pull rod is pulled smoothly and accurately to unlock, avoiding operational errors and difficulties during the unlocking process. This allows users to choose different locking methods according to different usage scenarios. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1: As Figure 1-7 As shown, the present invention provides a metal tooth zipper with a self-locking structure, comprising a chain belt 1 and a locking component 12. A chain 2 is fixedly installed on the outer surface of the chain belt 1, a zipper head 3 is provided on the outer surface of the chain 2, a stop block 4 is fixedly installed on the outer surface of the zipper head 3, a first pull ring 5 and a second pull ring 6 are provided on the inner surface of the zipper head 3, a limit block 7 is fixedly installed at the other end of the second pull ring 6 away from the zipper head 3, a limit component 8 is fixedly installed on the outer surface of the limit block 7, a slot 1 9 and a slot 2 10 are provided on the outer surface of the limit block 7, and a magnetic block 11 is fixedly installed on the inner surface of the limit block 7.
[0031] Specifically, the first pull ring 5 and the second pull ring 6 are located on the same horizontal plane, and the first pull ring 5 and the second pull ring 6 are located on both sides of the stop block 4. The advantage is that the pull ring design, which is located on the same horizontal plane and distributed on both sides of the stop block 4, provides users with more diverse operating options, allowing them to flexibly select the pull ring according to different usage scenarios and personal operating habits, thereby improving the convenience and comfort of operation.
[0032] Specifically, the zipper head 3, the first pull ring 5, the second pull ring 6, the limiting block 7, and the magnetic block 11 are all identical. The two zipper heads 3, the first pull ring 5, the second pull ring 6, and the limiting block 7 have the same structure. The two magnetic blocks 11 are magnetically connected. The advantage is that when the locking component 12 is not used, the design of the two magnetic blocks 11 can automatically lock the zipper head 3 when the zipper is closed, preventing the zipper from being accidentally opened due to shaking, collision, or other external forces. This improves the safety and stability of the zipper and is especially suitable for occasions where the zipper closure requirements are high, such as outdoor backpacks and sports equipment, to prevent items from falling and being lost.
[0033] Specifically, the limiting component 8 includes a limiting box 801, a limiting frame 802 fixedly installed on the inner surface of the limiting box 801, a top cover 803 fixedly installed on the top of the limiting box 801, and a spring 804 fixedly installed on the outer surface of the limiting frame 802. A limiting post 805, a pull rod 806, and a hook 807 are fixedly installed at the other end of the spring 804 away from the limiting frame 802. The limiting component 8 is adapted to the locking component 12 via the limiting post 805. The limiting post 805 penetrates the limiting block 7 and extends into the interior of the slot 9. The advantage is that when the zipper is pulled to the closed position, the limiting blocks 7 on the two zipper heads 3 move closer to each other. Then, the insertion post 1203 of the locking component 12 is aligned with the slot 9 on the limiting block 7 and gently inserted. During insertion, the insert post 1203 presses against the limiting post 805, compressing the spring 804. When the insert post 1203 is fully inserted into the slot 9, the limiting post 805 will be locked into the positioning groove 1204 on the insert post 1203 by the elastic force of the spring 804. If unlocking is required, pull the lever 806. The lever 806 will drive the limiting post 805 out of the positioning groove 1204, and then the insert post 1203 can be pulled out of the slot 9. The action of the spring 804 and the limiting post 805 can ensure the firmness of the lock and effectively prevent the zipper from opening accidentally when pulled by external force.
[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.
[0035] Specifically, a sliding groove 808 is provided through the outer surface of the top cover 803. The sliding groove 808 is slidably connected to the pull rod 806. The advantage is that the sliding connection design between the sliding groove 808 on the top cover 803 and the pull rod 806 provides a convenient way for unlocking. Users can easily find the operating position of the pull rod 806 through the sliding groove 808. When pulling the pull rod 806, the sliding groove 808 can play a guiding and limiting role, making the movement of the pull rod 806 more stable and accurate, and avoiding unlocking difficulties caused by the pull rod 806 shaking or deviating from the direction.
[0036] Specifically, the locking assembly 12 includes a locking frame 1201 and a plug 1203. The outer surface of the plug 1203 is provided with a positioning groove 1204 and a second magnetic block 1205. The second magnetic block 1205 is magnetically connected to the first magnetic block 11. The advantage is that during the insertion process, the second magnetic block 1205 will attract the first magnetic block 11, which further assists in positioning and fixing the position of the plug 1203. Combined with the magnetic connection between the first magnetic block 11 and the second magnetic block 1205, the stability is further enhanced.
[0037] Specifically, the outer surface of the locking frame 1201 is fixedly equipped with a strip 1202 and a post 1203. The strip 1202 is inserted into the slot 10, and the post 1203 is inserted into the slot 9. The advantage is that after the zipper is closed, the strip 1202 on the locking frame 1201 is aligned with the slot 10 on the limiting block 7, and the post 1203 is aligned with the slot 9. Then the locking frame 1201 is pushed towards the limiting block 7, so that the strip 1202 is inserted into the slot 10 and the post 1203 is inserted into the slot 9. The insertion installation of the strip 1202 and the post 1203 can limit the zipper head 3 from multiple directions, preventing it from moving or detaching.
[0038] Working principle: In use, the chain 2 on the chain belt 1 opens and closes via the zipper head 3. The stop block 4 on the outer surface of the zipper head 3 prevents it from detaching from the chain belt 1. The user pulls the first pull ring 5 or the second pull ring 6, causing the zipper head 3 to move along the chain belt 1, making the teeth of the chain 2 mesh or disengage, thus opening and closing the zipper. When the zipper is fully closed, the magnetic blocks 11 on the two zipper heads 3 attract each other, initially fixing the position of the zipper head 3 and preventing accidental opening. When further locking of the zipper is required, the insert 1202 of the locking component 12 is inserted into the slot 10 of the limiting block 7, and the insert post 1203 is inserted into slot 9. During the insertion of the insert post 1203, the limiting post 805 in the limiting component 8 is compressed, causing the spring 804 to compress. When the insert 1203 is fully inserted, the limiting pin 805, under the elastic force of the spring 804, engages with the positioning groove 1204 of the insert 1203, thus locking it in place. Simultaneously, the magnetic block 1205 on the insert 1203 and the magnetic block 11 attract each other, further enhancing the stability of the lock. To unlock, pull the lever 806 in the sliding groove 808 on the top cover 803, causing the limiting pin 805 to disengage from the positioning groove 1204. Then, the insert 1203 can be pulled out of the slot 9, releasing the lock and allowing the zipper to open normally.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
