Description

Technical Field

[0001] This utility model relates to the technical field of slider zippers with a safety structure, and particularly to a slider zipper with a safety structure. Background Technology

[0002] In products such as suitcases, outdoor backpacks, and high-end storage boxes that require frequent opening and closing and have security requirements, slider zippers are the core components that realize the sealing and opening functions. Their security performance directly determines the product's anti-theft, anti-accidental opening, and reliability.

[0003] In real-world use, when the zipper is frequently pulled, the zipper pull moves back and forth on the zipper track. Due to insufficient friction between the bottom stop and the fabric tape, the zipper pull is prone to slipping when passing the bottom stop due to a lack of sufficient restraint. This slippage can seriously affect the normal function of the zipper, thereby impacting the overall product quality and user experience. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a slider zipper with a safety structure. This can solve the problem that in actual use scenarios, when the zipper is frequently pulled, the zipper head will move back and forth on the zipper track. Due to insufficient friction between the bottom stop and the fabric, the zipper head is prone to slipping when passing the bottom stop position due to insufficient restraint. This makes the zipper head prone to undesirable slippage at the bottom stop. Once this slippage occurs, it will seriously affect the normal use function of the zipper, and thus affect the quality of the entire product and the user experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slider zipper with a safety structure, comprising:

A locking groove is provided on the top of the pull tab.

[0007] The safety positioning component is located on the bottom stop of the zipper.

[0008] The safety positioning component includes two safety blocks, a top plate, and a blocking structure. The two safety blocks are fixedly connected to the top of the zipper stop and engage with the inside of the locking groove. The top of each safety block has a rotating groove, and one end of the top plate is rotatably connected to the inside of the corresponding rotating groove. The top plate is located inside the two rotating grooves. The blocking structure includes multiple rubber blocks, which are fixedly connected to both sides of the top plate. The inside of each of the two rotating grooves has multiple limiting grooves, and the multiple rubber blocks are interference-fitted with the inside of the corresponding limiting grooves.

[0029] Pull-down head 1: As the core moving part for opening and closing the zipper, it can slide along the zipper teeth to directly close or open the zipper; a docking groove 10 is provided at the top for cooperating with the docking slider 9 of the upper pull-down head 2, and at the same time, the internal hex bolt 8 passes through to fix the upper pull-down head 2; when it moves to the lower stop 6 of the zipper, it can be locked with the safety positioning component to prevent itself from sliding randomly.

[0030] Upper pull head 2: The top is fixedly connected to the ring column 3, which can move synchronously under the drive of the ring column 3; the bottom is fixedly connected to the docking slider 9, which slides into the docking groove 10 of the lower pull head 1 through the docking slider 9, and is fixed to the lower pull head 1 by means of the internal hex bolt 8, thereby transmitting its own moving force to the lower pull head 1, driving the lower pull head 1 to slide along the chain teeth;

[0031] Ring column 3: It has a "C" shaped structure, with the top fixedly connected to the upper pull head 2 and a pull ring 4 inside; it can move synchronously under the drive of the pull ring 4, thereby transmitting the pulling force to the upper pull head 2. At the same time, the "C" shaped structure can keep the pull ring 4 in a stable force state inside it.

[0032] Pull ring 4: It is fixedly connected to the pull plate 5 internally and set inside the ring post 3 externally; it can move synchronously under the drive of the pull plate 5, and transmit the pulling force of the pull plate 5 to the ring post 3. At the same time, it remains stable within the "C"-shaped structure of the ring post 3 to ensure effective force transmission.

[0033] Pull tab 5: for users to hold and apply pulling force, and drives the pull tab 4 to move through the fixed connection with the pull ring 4; a locking groove 7 is provided at the top, which can engage with the safety block 11 on the zipper stop 6, initially restricting the movement of itself and the pull head 1, and is the key trigger component for realizing the zipper safety lock;

[0034] Zipper bottom stop 6: As the end limiting structure of the zipper, it restricts the movement range of the pull-down head 1, so that the pull-down head 1 can be locked at this point; two safety blocks 11 are symmetrically fixedly connected at the top, and the top of the safety block 11 is provided with a rotating groove 15, which provides an installation base for the safety positioning component and is the core bearing component of the zipper safety locking function;

[0035] Locking groove 7: It is opened on the top of the pull tab 5 and can be fully engaged with the two safety blocks 11 on the zipper stop 6. The engagement initially restricts the movement of the pull tab 5 and the pull head 1, providing a basis for the subsequent covering and locking of the top plate 12. It is the key structure for achieving initial locking.

[0036] Hex socket bolt 8: passes through the pull-down head 1 and is threadedly connected to the docking slider 9 at the bottom of the pull-up head 2. The docking slider 9 is fixedly installed in the docking groove 10 of the pull-down head 1 through the thread fastening action, thereby realizing a stable connection between the pull-up head 2 and the pull-down head 1 and ensuring that the two move synchronously.

[0037] The docking slider 9 is fixedly connected to the bottom of the upper pull head 2 and can be slidably inserted into the docking groove 10 at the top of the lower pull head 1 to achieve the initial assembly of the upper pull head 2 and the lower pull head 1; at the same time, it is threadedly connected to the internal hex bolt 8. Through the fixing effect of the internal hex bolt 8, the upper pull head 2 and the lower pull head 1 form a stable whole, which facilitates the transmission of force.

[0038] The docking groove 10 is located on the top of the pull-down head 1, allowing the docking slider 9 at the bottom of the pull-up head 2 to slide and engage, providing guidance and space for the assembly of the pull-up head 2 and the pull-down head 1, ensuring precise docking, and also working with the hexagon socket bolts 8 to fix the two together.

[0039] Safety latch 11: There are two in total, both made of rubber and symmetrically fixed to the top of the zipper stop 6. They can engage with the locking groove 7 on the top of the pull tab 5. The properties of the rubber material enhance the stability of the engagement and initially restrict the movement of the pull tab 5 and the pull head 1. A rotating groove 15 is provided on the top to provide installation space for the rotation of the top plate 12. It is the core structure for initial locking in the safety positioning assembly.

[0040] Top plate 12: One end is rotatably connected to the rotating groove 15 on the top of the safety block 11, and can rotate within the rotating groove 15; after rotation, it can cover the locking part of the locking groove 7 and the safety block 11, preventing the safety block 11 from disengaging from the locking groove 7; rubber blocks 13 or embedded magnetic plates 17 can be fixedly connected to both sides, and together with the blocking structure, they are kept in the locked position, which is the key structure for secondary locking in the safety positioning assembly;

[0041] Rubber blocks 13: As a type of blocking structure, there are multiple blocks, which are fixedly connected to both sides of the top plate 12. When the top plate 12 is rotated to the locked position, the rubber blocks 13 form an interference fit with the limiting groove 14 inside the rotating groove 15. The elastic deformation of the rubber blocks 13 clamps the limiting groove 14, restricting the top plate 12 from rotating in the opposite direction and ensuring that the top plate 12 is stably kept in the locked position.

[0042] Limiting groove 14: As a cooperating part of the blocking structure, there are multiple grooves, which are opened inside the rotating groove 15; they can form an interference fit with the rubber blocks 13 on both sides of the top plate 12, and by accommodating the rubber blocks 13 and using the friction generated by their elastic deformation, the top plate 12 is restricted from rotating in the opposite direction, providing a clamping base for the rubber blocks 13 and ensuring that the blocking structure is effective.

[0043] Rotating groove 15: It is opened on the top of the two safety blocks 11, providing a rotating installation space for one end of the top plate 12, so that the top plate 12 can rotate around the rotating groove 15; a limiting groove 14 or an embedded magnetic piece 16 can be opened inside, which, together with the corresponding structure on the top plate 12, forms a block, which is the key spatial structure for the top plate 12 to achieve rotation and stable locking.

[0044] Magnetic suction piece 16: As another form of blocking structure, there are multiple magnetic suction pieces 16, which are embedded in the rotating groove 15 respectively. When the top plate 12 is rotated to the locked position, the magnetic suction piece 16 and the magnetic suction piece 17 embedded on both sides of the top plate 12 generate a magnetic attraction force. The magnetic attraction keeps the top plate 12 stably in the locked position and restricts the top plate 12 from rotating in the opposite direction.

[0045] Magnetic absorbing piece 2 17: As a cooperating part of the blocking structure, there are multiple pieces, which are embedded in both sides of the top plate 12 respectively; when the top plate 12 is rotated to the locked position, the magnetic absorbing piece 2 17 and the magnetic absorbing piece 16 inside the rotating groove 15 generate a magnetic attraction force, and the top plate 12 is stably kept in the locked position through magnetic force cooperation, preventing the top plate 12 from rotating at will and ensuring the stability of the safety locking function.

[0046] Example 1:

[0047] like Figure 1-5 As shown, the safety positioning component uses a rubber block 13 and a limiting groove 14 with an interference fit;

[0048] Two safety catch blocks 11 are symmetrically arranged at the top of the zipper stop 6, which engage with the locking groove 7;

[0049] The top plate 12 rotates through the rotating groove 15, and the rubber block 13 is embedded in the limiting groove 14 to achieve positioning. After the user closes the zipper, the top plate 12 is rotated to make the rubber block 13 lock into the limiting groove 14. The friction force is used to prevent the zipper head from sliding due to shaking, thus avoiding accidental exposure of items.

[0050] Example 2:

[0051] like Figure 6 As shown, outdoor hiking backpacks need to be opened and closed frequently to take out and put away equipment, and the backpacks are easily bumped and collided during the mountain climbing process. Therefore, a pull-top positioning structure is needed that is both stable and easy to unlock quickly.

[0052] After the climber puts the equipment into the backpack, he pulls the pull tab 5 to close the zipper with the pull head 1 until the pull head 1 is in contact with the bottom stop 6 of the zipper.

[0053] Push the pull tab 5 so that the safety block 11 of the zipper stop 6 engages with the locking groove 7 of the pull tab 5. Then rotate the top plate 12. The magnetic suction pieces 17 embedded on both sides of the top plate 12 quickly magnetically attract the magnetic suction pieces 16 in the rotation groove 15, instantly fixing the top plate 12 and completing the positioning of the zipper head.

[0054] When it is necessary to retrieve or put away equipment, the climber only needs to overcome the magnetic attraction of the magnetic plate with one hand, rotate the top plate 12 back to the rotating groove 15, pull the pull tab 5 to disengage the safety block 11 from the locking groove 7, and then quickly open the zipper.

[0055] The magnetic locator 16 and magnetic locator 27 have a fast magnetic positioning speed, which is suitable for the quick operation needs during mountaineering; and the magnetic force is strong enough to resist the vibration caused by the backpack's bumps, preventing the zipper from being accidentally unlocked. At the same time, unlocking does not require extra force, improving the convenience of outdoor use.

[0056] Furthermore, when using this device, during normal zipper opening and closing, the user applies pulling force by holding the pull tab 5. The pull tab 5 drives the pull ring 4, which is fixedly connected to it. The pull ring 4 maintains a stable force state within the "C"-shaped ring post 3, thereby driving the upper zipper head 2 to move synchronously through the ring post 3. Since the docking slider 9 at the bottom of the upper zipper head 2 is slidably inserted into the docking groove 10 at the top of the lower zipper head 1 and is fixed by the internal hex bolt 8, the movement of the upper zipper head 2 will directly drive the lower zipper head 1 to slide along the zipper teeth, ultimately realizing the zipper's closing or opening, meeting daily opening and closing needs.

[0057] When it is necessary to prevent the zipper pull from sliding freely, the pull tab 1 moves to the bottom stop of the zipper 6. The locking groove 7 at the top of the pull tab 5 aligns with the two safety blocks 11 symmetrically arranged at the top of the bottom stop of the zipper 6. Both safety blocks 11 are made of rubber. The user pushes the pull tab 5 so that the two safety blocks 11 are fully engaged in the locking groove 7, initially restricting the movement of the pull tab 5 and the pull tab 1. Then, the top plate 12 is rotated, and one end of the top plate 12 rotates in the rotating groove 15 at the top of the safety blocks 11 until the top plate 12 covers the engagement part of the locking groove 7 and the safety blocks 11.

[0058] At this time, if the blocking structure is a combination of rubber block 13 and limiting groove 14: multiple rubber blocks 13 on both sides of the top plate 12 will form an interference fit with the corresponding limiting groove 14 inside the rotating groove 15, and the limiting groove 14 will be locked by the elastic deformation of the rubber block 13, thus restricting the reverse rotation of the top plate 12; if the blocking structure is a combination of magnetic absorbing piece 16 and magnetic absorbing piece 17: the magnetic absorbing piece 17 embedded on both sides of the top plate 12 will generate a magnetic attraction force with the corresponding magnetic absorbing piece 16 embedded inside the rotating groove 15, so that the top plate 12 is stably kept in the locked position, preventing the safety block 11 from disengaging from the locking groove 7, and finally achieving the safety lock of the zipper to prevent accidental opening.

[0059] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
