Description

Technical Field

[0001] This utility model belongs to the technical field of zipper accessories, specifically relating to a zipper head with anti-slip function. Background Technology

[0002] As a connecting component of a zipper that can be opened and closed, the zipper pull is widely used in leather bags and garments due to its convenient operation. The existing zipper pull consists of a zipper head and a pull tab. The pull tab is made of zinc alloy metal body and has a plastic covering on the outside of the end connected to the zipper head. At the same time, the zipper pull is provided with a pull nose for the pull tab to hook and position the zipper head and pull tab in combination.

[0003] Common zipper pulls are prone to detaching from the zipper during use, causing inconvenience to users. Therefore, utility model patent (CN212280209U) proposes a zipper pull with an anti-detachment function, including a zipper pull body, a positioning block fixedly mounted on the zipper pull body, a pull ring passing through the positioning block, a connecting rod fixedly mounted on the pull ring, a pull tab mounted on the end of the connecting rod away from the pull ring, symmetrically arranged aggregation grooves inside the zipper pull body, a partition fixedly mounted between the aggregation grooves, a locking block below the partition, a first sliding groove inside the positioning block, a second sliding groove on one side of the first sliding groove, a pushing block inside the first sliding groove, one side of the pushing block fixedly connected to the locking block, and the side of the pushing block away from the locking block fixedly connected to a limiting block, the first limiting block fixedly mounted on the outside of the sliding rod, the second limiting block fixedly mounted on the outside of the sliding rod, and a return spring fixedly mounted on the outside of the sliding rod, located between the second limiting block and the inner wall of the first sliding groove. Beneficial effects: Prevents the zipper pull from easily falling off when not in use; simple structure and easy operation improve practicality.

[0004] In existing technologies, to prevent zipper pulls from automatically detaching, a spring is typically installed inside the zipper pull. This spring is pulled by the pull ring, and when the zipper pull is in position, the spring engages with the pull ring due to its own elasticity, thus preventing detachment. However, the spring's detachment prevention relies solely on its own elastic potential energy, which has limited elasticity and therefore a limited effectiveness. Furthermore, excessive force applied by the user during zipper pull pulling may cause irreversible deformation of the spring, rendering it ineffective. Therefore, an improved zipper pull design with an anti-detachment function has been developed. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a zipper head with anti-detachment function to solve the problems in the background technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A zipper head with anti-detachment function includes a zipper head composed of a base plate, a pressure plate and a connecting post. The upper part of the pressure plate is connected to a fixing ring, and the zipper head also includes a pull ring movably connected to the fixing ring. The pressure plate is provided with an anti-detachment component, which can press the zipper located between the base plate and the pressure plate or release the press when the pull ring is activated.

[0008] Furthermore, the pressure plate has a through-hole groove that penetrates the plate body, and the anti-detachment component is installed in the through-hole groove.

[0009] Furthermore, the anti-detachment component includes;

[0010] A fixed shaft is fixedly installed in a through-hole groove;

[0011] The movable rod is vertically movably disposed in the through-hole groove. A sliding groove is formed on the rod body, and the fixed axis is located in the sliding groove. The top of the movable rod is connected to a top plate located outside the pressure plate, and the bottom of the movable rod is connected to a pressure block located inside the pressure plate.

[0012] Furthermore, the side of the pressure block away from the movable rod is an inclined plate structure, which can engage with the zipper pull tab to achieve the function of preventing the zipper head from slipping off.

[0013] Furthermore, the top plate has a circular structure, the bottom edge of the top plate is rounded, and the pull ring is located between the top plate and the pressure plate.

[0014] Furthermore, a pull ring sleeve is connected to the pull ring, and the pull ring sleeve is provided with anti-slip texture.

[0015] Furthermore, the upper and lower ends of the groove are arc-shaped grooves.

[0016] Furthermore, the connecting column is connected between the base plate and the pressure plate, the base plate is provided with lower limit plates on both sides, and the pressure plate is provided with upper limit plates on both sides.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] This zipper pull consists of a base plate, a pressure plate, and a connecting post. A fixing ring is fixedly connected to the surface of the pressure plate for connection with the pull ring. An anti-detachment component is also installed on the pressure plate. This anti-detachment component is triggered by the pull ring to tighten or loosen the zipper. Specifically, when the zipper needs to be opened, the zipper is released from its tension, and the pull ring is pulled downwards. At this time, the pull ring is located between the top plate and the pressure plate and is pulled downwards. Simultaneously, the movable rod moves upwards and deflects around a fixed axis to the right, causing the pressure block at the bottom of the movable rod to rotate to the upper left, thus disengaging from the zipper and releasing the tension, allowing the zipper to be easily opened. When the zipper is not needed, due to the weight of the anti-detachment component, the movable rod and pressure block are in a downward state. The inclined plate structure at the bottom of the pressure block engages with the zipper pull tab to achieve the anti-detachment function of the zipper pull. Attached Figure Description

[0029] Example:

[0030] like Figure 1-4 As shown, this utility model is a zipper pull with an anti-detachment function. Specifically, it includes a zipper pull composed of a base plate 1, a pressure plate 2, and a connecting post 3. A fixing ring 4 is connected to the upper part of the pressure plate 2, and a pull ring 5 is movably connected to the fixing ring 4. An anti-detachment component 7 is provided on the pressure plate 2. The anti-detachment component 7 can press the zipper located between the base plate 1 and the pressure plate 2 or release the press when the pull ring 5 is activated.

[0031] The pressure plate 2 has a through-hole groove 202 that penetrates the plate body, and the anti-detachment component 7 is installed on the through-hole groove 202.

[0032] Anti-detachment component 7 includes;

[0033] Fixed shaft 701 is fixedly installed in through hole groove 202;

[0034] The movable rod 702 is vertically movably disposed in the through hole groove 202. A sliding groove 7021 is provided on the rod body of the movable rod 702, and the fixed shaft 701 is located in the sliding groove 7021. The top of the movable rod 702 is connected to the top plate 703 located outside the pressure plate 2, and the bottom of the movable rod 702 is connected to the pressure block 704 located inside the pressure plate 2.

[0035] The side of the pressure block 704 away from the movable rod 702 is an inclined plate structure. The inclined plate structure can engage with the zipper pull tab to achieve the function of preventing the zipper head from coming off.

[0036] The top plate 703 has a circular structure, and the bottom edge of the top plate 703 is rounded. The pull ring 5 is located between the top plate 703 and the pressure plate 2.

[0037] Pull ring 5 is connected to pull ring sleeve 6, and pull ring sleeve 6 is provided with anti-slip texture.

[0038] The upper and lower ends of the 7021 slide are arc-shaped grooves.

[0039] The connecting column 3 is connected between the base plate 1 and the pressure plate 2. The base plate 1 has a lower limit plate 101 on both sides, and the pressure plate 2 has an upper limit plate 201 on both sides.

[0040] Working principle: This zipper head consists of a base plate 1, a pressure plate 2, and a connecting post 3. A fixing ring 4 is fixedly connected to the surface of the pressure plate 2 for connection with the pull ring 5. An anti-detachment component 7 is also provided on the pressure plate 2. This anti-detachment component 7 is triggered by the pull ring 5 to tighten or loosen the zipper. Specifically, when the zipper needs to be opened, the zipper is loosened, and the pull ring 5 is pulled downwards. At this time, the pull ring 5 is located between the top plate 703 and the pressure plate 2 and is pulled downwards. Figure 4 As can be seen, even if the movable rod 702 moves upward and deflects around the fixed axis 701 to the right, the pressure block 704 at the bottom of the movable rod 702 rotates to the upper left, thereby disengaging from the zipper and releasing the pressing state, so that the zipper can be easily opened. When the zipper does not need to be opened, due to the weight of the anti-detachment component 7, the movable rod 702 and the pressure block 704 are in a downward state. The inclined plate structure at the bottom of the pressure block 704 engages with the zipper pull tab to achieve the anti-detachment function of the zipper head.
