[0001] The utility model relates to a zipper, in particular to a mutually - spliced different - tooth zipper structure. Background Art

[0002] A zipper is a connecting piece that relies on continuously arranged chain teeth to join or separate items, and is now widely used in clothing, bags, tents, etc. A zipper consists of chain teeth, a slider, upper and lower stops (front and rear codes) or locking pieces, etc. Among them, the chain teeth are the key part, which directly determines the side - pull strength of the zipper. Generally, a zipper has two tape bodies, each tape body has a row of chain teeth respectively, and the two rows of chain teeth are arranged in an interlaced manner. The slider clamps the chain teeth on both sides and slides along the pull tab, so that the chain teeth on both sides can be engaged or disengaged with each other.

[0003] At present, the left - and - right tooth structures of plastic - steel tooth zippers are mostly of the same shape and appearance. When processing zippers, only chains with the same tooth shape and size can be spliced and used correspondingly. Different - shaped teeth require different - shaped molds to be made, resulting in high production costs and poor combinability. For the above reasons, it is necessary to design a mutually - spliced different - tooth zipper structure that can combine zippers with a variety of different teeth to increase the combinability of zippers.

[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the following further describes the embodiments of the present disclosure in a clearer and more detailed manner with reference to the accompanying drawings of the present embodiment. Note: The described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0026] As shown in the attached Figure 1 and the attached Figure 2As shown, when the interlocking zipper with different teeth is used to splice multiple zippers with different teeth, the interlocking zipper with different teeth structure includes a first belt body 11 and a second belt body 21, one end of the first belt body 11 is provided with a socket 12, a zipper head 3 is slidably provided on the first belt body 11, and one end of the second belt body 21 is provided with a latch 22 that matches the socket 12. According to the existing zipper principle, it can be known that the current zipper mostly uses two chains with the same structure, and the connection of the zipper structure is achieved by the insertion of the latch 22 on one chain and the slot of the socket 12 on the other chain. After pulling the zipper head 3, the teeth on the two chains can be simultaneously passed through the grooves between the two fixing pins of the zipper head 3, and the chain teeth are staggered through the fixing pins. The chain teeth on one chain belt are pressed onto the chain teeth of the other chain belt, so that the two chain belts can be pulled together or apart. The first belt body 11 is provided with a first tooth 61, the second belt body 21 is provided with a second tooth 62 that matches the first tooth 61, a connecting groove 4 is provided in the slot of the socket 12, and a connecting piece 5 is provided in the connecting groove 4, which is used for the mutual connection of multiple different-tooth zippers. And the first tooth 61 and the second tooth 62 proposed in this embodiment are both made of plastic materials. When the two chain belts of the zipper are spliced ​​and used, the shapes and sizes of the teeth of the two chain belts that are spliced ​​can be the same or different. When the two chain belts are spliced ​​and used, the connecting piece 5 can limit and fix the pin 22 on the other chain of the splicing, so as to fix the ends of the two chain belts, so that the zipper head 3 can still pull the two chains together or apart, increase the application diversity of the zipper, realize the mutual splicing of multiple zipper chains, increase the combination of the zipper, and reduce the production cost of the chain.

[0027] It is worth noting that, in some embodiments, Figure 1 As shown, when the zipper uses two chains with the same teeth to splice, the first teeth 61 on the first belt body 11 will have the same structure as the second teeth 62 on the second belt body 21. By pulling the zipper head 3 back and forth, the teeth on the two belt bodies will be staggered and inserted into the gap between two adjacent teeth. The zipper can be opened or closed by the meshing connection of the teeth on the same two chains.

[0028] In other embodiments, Figure 2 As shown, when a zipper uses two chains with different teeth for splicing, the meshing connection of different teeth on the two chains is achieved through the common setting of the meshing parts on the two teeth, so that the zipper can be opened or closed, and the meshing parts between two adjacent teeth together form a gap. When the two chain belts are meshed and spliced, the teeth on the two chain belts will be staggered and stuck in the gap, which facilitates the meshing use of teeth with different structures and facilitates the combined use of multiple tooth chains.

[0029] In order to better facilitate the combined use of zipper chains, such as Figure 3As shown, a limiting end 23 can be provided at one end of the bolt 22 close to the second belt body 21 to increase the width of the bolt 22 near the tooth end, facilitating the limiting connection between the bolt 22 and the socket 12; and through the setting of the chamfer at the edge of the limiting end 23, it is convenient to insert and use the bolt 22 and the socket 12.

[0030] Furthermore, when the bolt 22 and the socket 12 are inserted and used, in some embodiments, the bolt 22 can be improved, such as Figure 3 As shown, by providing a convex block 24 on the bolt 22, the roughness of the surface of the bolt 22 can be increased, the connection friction between the bolt 22 and the socket 12 can be increased, the connection firmness between the bolt 22 and the socket 12 can be increased, the structural stability of the zipper chain combination can be improved, and the convex block 24 and the bolt 22 can be set as an integral structure of the same material, facilitating the production of its structure, reducing the production cost, and increasing the connection firmness between the bolt 22 and the convex block 24.

[0031] In order to better facilitate the splicing use between zipper chains, the structure of the connecting piece 5 will be further limited, such as Figure 4 As shown, the connecting piece 5 includes a fitting end 51 fixedly connected to the connecting groove 4, and the other end of the connecting piece 5 is provided with an inclined end 52, and the inclined end 52 inclines towards the slot of the socket 12. The fitting end 51 and the inclined end 52 form an acute angle. Through the inclined setting between the inclined end 52 and the fitting end 51, it is convenient for clamping when the bolt 22 is inserted into the socket 12, providing convenience for the connection between the chain and the first belt body 11, and increasing the convenience of mutual splicing use between the chains.

[0032] In order to further increase the insertion firmness between the socket 12 and the bolt 22, such as Figure 5 As shown, a plurality of rough strips 53 can be provided on the side of the inclined end 52 away from the connecting groove 4, and the heights of the plurality of rough strips 53 increase sequentially towards the opening of the connecting groove 4. Through the sequential increase of the plurality of rough strips 53 towards the opening of the connecting groove 4, it is convenient to increase the width of the connection between the fitting end 51 and the inclined end 52, increase the elasticity of the connection, and when the bolt 22 penetrates the slot, the plurality of rough strips 53 can be used to limit the bolt 22, facilitating the insertion of bolts 22 with different thicknesses in the slot, increasing the versatility of the socket 12, facilitating the mutual splicing use of various chains, and increasing the diversity of mutual splicing use of the zipper.

[0033] In order to further facilitate the mutual splicing connection between the socket 12 and the bolt 22, such as Figure 4 and 5As shown, in some embodiments, the adapter 5 can be improved. An arc-shaped plate 54 is provided at the tail end of the adapter 5, and an arc-shaped groove 411 matching the arc-shaped plate 54 is formed on the connection groove 4, which facilitates the adapter 5 to be received in the connection groove 4 when being squeezed, provides conditions for the angular offset of the inclined end 52, realizes the limit of the adapter 5 in the socket 12, avoids the offset of the adapter 5, and increases the connection firmness between the plug pin 22 and the socket 12.

[0034] Certainly, the above description is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications are also regarded as the protection scope of the present invention.
