Description

Technical Field

[0001] The utility model relates to the technical field of hardware, in particular to a T-shaped multi-chain zipper. Background Art

[0002] A zipper is composed of chain teeth, a slider, upper and lower stops (front and rear stops) or locking parts, among which the chain teeth are the key part, which directly determines the side pull strength of the zipper. Generally, a zipper has two chain belts, each of which has a row of chain teeth. The two rows of chain teeth are staggered with each other. The slider clamps the chain teeth on both sides, and the chain teeth on both sides can be engaged or disengaged with the help of the pull loop sliding. T-type zippers are the common mainstream zippers on the market.

[0003] The zipper head handles of existing zippers on the market cannot remain stable, and users need to manually return them to their original position to make them parallel to the zipper head after use. However, during use, the zipper head handle is prone to swing again due to the shaking, which is not only easy to scratch objects and collide with objects, but also easy to injure users, causing serious troubles to users.

[0006] The zipper body comprises two chain teeth and a zipper head mounted on the two chain teeth. Two hinge seats are symmetrically arranged on the top of the zipper head. A rotating cylinder is arranged inside the hinge seat through a spring. A zipper handle is movably arranged between the two rotating cylinders.

[0007] Furthermore, a circle of tooth grooves is provided inside the rotating drum, and gear shafts are provided on both sides of one end of the zipper handle, and one end of the gear shaft away from the zipper handle is movably inserted into the inside of the tooth groove.

[0008] Furthermore, an avoidance groove is provided at one end of the zipper handle.

[0009] Furthermore, a plurality of anti-slip strips are provided on the top and bottom of the zipper handle.

[0010] Furthermore, a circle of mounting grooves is provided on one side of the inner wall of the hinge seat, the spring is arranged inside the mounting groove and guide posts are provided at both ends of the spring.

[0011] Furthermore, a spacer block located between the two guide pillars is fixedly arranged inside the installation groove.

[0012] Furthermore, a driving rod is provided at one end of the rotating drum away from the gear shaft.

[0013] Furthermore, the driving rod is L-shaped, and one end of the driving rod away from the rotating drum extends to the inside of the mounting groove and is provided with a circular plate.

[0014] Compared with the prior art, the utility model provides a T-shaped multi-chain zipper, which has the following beneficial effects:

[0015] The T-shaped multi-chain zipper limits the zipper handle by a spring. When the user flips the zipper handle, the spring is compressed.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5The utility model discloses a T-shaped multi-chain zipper, including a zipper connecting belt 1, on which at least two zipper bodies 11 are arranged, and on which extension belts 12 located on both sides of one of the zipper bodies 11 are also arranged. The multi-chain design can increase the width of the entire zipper connecting belt 1 when the zipper body 11 corresponding to the extension belt 12 is pulled apart, making it more convenient to use.

[0024] The zipper body 11 includes two chain teeth and a zipper head 2 mounted on the two chain teeth, and two hinged seats 21 are symmetrically arranged on the top of the zipper head 2. A rotating drum 25 is arranged inside the hinged seat 21 through a spring, and a zipper handle 22 is movably arranged between the two rotating drums 25. When installing the zipper handle 22, the zipper handle 22 is kept parallel to the zipper head 2, and the two gear shafts 26 are brought close to each other by pinching the two sides of the zipper handle 22. The zipper handle 22 is moved from any side of the two sides of the zipper head 2 to between the two hinged seats 21, and then the two gear shafts 26 are connected to the two tooth grooves one by one. When the user flips the zipper handle 22 to pull the zipper head 2, the gear shaft 26 drives the rotating drum 25 to rotate, and the rotating drum 25 compresses the spring through the driving rod 29, and the zipper handle 22 is released. The spring rebound drives the zipper handle 22 to automatically reset.

[0025] Specifically, a circle of tooth grooves is provided inside the rotating drum 25 , and gear shafts 26 are provided on both sides of one end of the zipper handle 22 , and one end of the gear shaft 26 away from the zipper handle 22 is movably inserted into the inside of the tooth groove.

[0026] Specifically, an escape groove 24 is provided at one end of the zipper handle 22. The zipper handle 22 is made of an elastic metal material. The setting of the escape groove 24 allows the gear shaft 26 to be driven out of the tooth groove by pinching both sides of the zipper handle 22, which makes disassembly and assembly more convenient. If it is damaged later, it can be replaced independently without replacing the entire zipper head 2.

[0027] Specifically, a plurality of anti-slip strips 23 are provided at the top and the bottom of the zipper handle 22 . The provision of the anti-slip strips 23 makes it more stable for the user to hold the zipper handle 22 .

[0028] Specifically, a circle of mounting grooves 27 are provided on one side of the inner wall of the hinge seat 21, a spring is arranged inside the mounting groove 27 and guide posts 271 are arranged at both ends of the spring, a spacer 28 located between the two guide posts 271 is fixedly arranged inside the mounting groove 27, a driving rod 29 is arranged at one end of the rotating cylinder 25 away from the gear shaft 26, and the driving rod 29 is L-shaped, and the end of the driving rod 29 away from the rotating cylinder 25 extends to the inside of the mounting groove 27 and is provided with a circular plate, see Figure 4-5The spacer 28 separates the guide columns 271 at both ends of the spring, so that when one of the guide columns 271 is resisted, the position of the other guide column 271 is kept stable, thereby compressing the spring. One end of the drive rod 29 extends to the inside of the mounting groove 27. This design not only enables the rotating drum 25 to drive the circular plate to resist the guide column 271 when rotating, but also because one end of the drive rod 29 is limited by the mounting groove 27, the rotating drum 25 cannot be withdrawn from the inside of the hinge seat 21, thereby ensuring the stability of the rotating drum 25.

[0029] To summarize, the T-shaped multi-chain zipper limits the zipper handle 22 by a spring. When the user flips the zipper handle 22, the spring will be compressed. When the zipper handle 22 is released, the zipper handle 22 will automatically reset. This design can effectively prevent the zipper handle 22 from scratching objects and injuring users. The detachable zipper handle 22 is easy to assemble and disassemble, and can be replaced independently if damaged at a later time. There is no need to replace the entire zipper head 2. The use cost is low and meets the user's needs.
