Description

TECHNICAL FIELD

[0001] The utility model relates to a luggage accessory, in particular to a theftproof zipper. BACKGROUND

[0002] The two-way zipper is one of important accessories in luggage, which realizes fast and wide opening or closing of the luggage through two zipper heads. Due to the convenience of the zipper, theft personnel can easily steal by pulling open the zipper in the environment of crowded or mixed personnel, and the existing theftproof zipper has complex structure and numerous mechanisms, which not only has high cost and cannot be popularized, but also is easy to be damaged, further increasing the use cost of users.

[0003] Therefore, there is an urgent need for a new theftproof zipper, which has simple structure, certain theftproof effect, increases the opportunity for users to find theft and creates certain obstacles for theft personnel. UTILITY MODEL CONTENT

[0004] In order to solve the above technical problems, the utility model provides a theftproof zipper, which has simple structure, certain theftproof effect, increases the opportunity for users to find theft and creates certain obstacles for theft personnel.

[0005] The utility model adopts the following technical scheme:

[0006] A theftproof zipper, which comprises a zipper tape and two oppositely arranged zipper heads, the zipper head comprises a zipper head body, an intermediate piece connected with the zipper head body and a pull tab connected with the intermediate piece, the pull tab has an 8-shaped structure, the pull tab comprises a first pull tab block sleeved with the intermediate piece and two second pull tab blocks respectively connected with the edges of the first pull tab block through a first clamping mechanism, the first clamping mechanism comprises a clamping block arranged on the end face of the first pull tab block in an arc-shaped structure and a clamping hole arranged on the second pull tab block in an arc-shaped structure and abutting against the end face of the first pull tab block, and the second pull tab block is made of soft material.

[0007] Further, the intermediate piece and the zipper head body are fixedly connected or movably connected, when movable connection is needed, the intermediate piece and the zipper head body are connected through a second clamping mechanism, the intermediate piece has a U-shaped structure, and the second clamping mechanism comprises a clamping body arranged on the upper end face of the zipper head body in a T-shaped structure and a clamping groove arranged on the end face of the intermediate piece and matched with the clamping body.

[0008] Further, the clamping block and the first pull tab block are integrally formed, the clamping body and the zipper head body are integrally formed, the first pull tab block and the intermediate piece are made of hard metal material, the second pull tab block is made of soft silica gel material or soft rubber material, the clamping block is extruded into the variable clamping hole, and the connection between the first pull tab block and the second pull tab block is realized.

[0009] Preferably, one end of the intermediate component is rotatably connected to the slider body via a second snap-fit ​​mechanism, and the other end is separated from the slider body, so that the intermediate component can rotate. In order to prevent the pull tab that is sleeved with the intermediate component from detaching from the intermediate component, a limiting block is fixed on both sides of the upper surface of the slider body to limit the rotation range of the intermediate component. In order to improve the aesthetics, the limiting block adopts a sail-shaped structure.

[0010] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. The second pull tab is made of soft material, the first pull tab and the two second pull tabs form a connecting space, and the abutting parts of the two second pull tabs are separate structures. When anti-theft is required, the two zipper heads twist and squeeze into the connecting space through the gap between the two second pull tabs to form an interlocking structure, achieving a certain anti-theft effect, increasing the difficulty of theft for thieves, and increasing the chance of users discovering the theft; 2. The intermediate part achieves mutual rotation with the zipper head body through the second snap-fit ​​mechanism, increasing the range of movement between the pull tab and the zipper head body, which not only enhances the durability of the zipper, but also improves the convenience for users to interlock the two pull tabs; 3. This utility model has a simple structure, low cost, and is conducive to mass production. Attached Figure Description

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] See Figures 1 to 6 An anti-theft zipper includes a chain tooth belt 1 and two opposing zipper heads 2. Each zipper head 2 includes a zipper head body 21, an intermediate component 22 connected to the zipper head body 21, and a zipper tab 23 connected to the intermediate component 22. The zipper tab 23 has a figure-eight structure and includes a first zipper tab block 231 sleeved with the intermediate component 22 and two second zipper tab blocks 232 respectively engaged with the edges of the first zipper tab block 231 by a first engaging mechanism 3. The first engaging mechanism 3 includes an arc-shaped locking block 4 fixedly disposed on the end face of the first zipper tab block 231 and an arc-shaped locking hole 41 opened on the second zipper tab block 232 that abuts against the end face of the first zipper tab block 231. The second zipper tab block 232 is made of a soft material.

[0021] See Figure 2 , Figures 5 to 6 To further enhance the anti-theft effect, the intermediate component 22 adopts a wobbling and rotating design. The intermediate component 22 is connected to the zipper head 21 through the second snap-fit ​​mechanism 5. The intermediate component 22 has a U-shaped structure. The second snap-fit ​​mechanism 5 includes a T-shaped snap-fit ​​body 6 fixedly disposed on the upper end face of the zipper head 21 and a snap-fit ​​groove 7 opened on one end face of the intermediate component 22 and adapted to the snap-fit ​​body.

[0022] See Figures 2 to 6 The locking block 4 and the first pull tab block 231 are integrally formed, the locking body 6 and the pull head body 21 are integrally formed, the first pull tab block 231 and the intermediate part 22 are both made of hard metal, preferably stainless steel, and the second pull tab block 232 is made of soft silicone or soft rubber. The locking block 4 is squeezed into the variable locking hole 41 to realize the connection between the first pull tab block 231 and the second pull tab block 232. At the same time, in order to prevent the pull tab 23 that is sleeved with the intermediate part 22 from detaching from the intermediate part 22, a limit block 8 with a sail-shaped structure is fixed on both sides of the upper surface of the pull head body 21 to limit the rotation range of the intermediate part 22.

[0023] Working principle: This utility model uses a second pull tab 232 made of soft material to connect and interlock the two pull heads 2 through the pull tab 23. When thieves steal, they need to do more work to open it, which increases the difficulty of theft and also increases the chance for users to discover that theft has been discovered, thus achieving the anti-theft effect. At the same time, its structure is simple, not prone to failure, and low in cost, which is conducive to large-scale production and promotion by enterprises.

[0024] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
