Description

Technical Field

[0001] The utility model belongs to the technical field of zippers, and in particular relates to a chain tooth structure with explosion-proof teeth and a zipper. Background Art

[0002] Zippers, as the most common connection device in life, rely on continuously arranged chain teeth to achieve convenient merging and separation of objects. They are widely used in many fields such as clothing, bags, tents, etc. With the progress of the times, the structure and manufacturing materials of zippers are also constantly evolving, from traditional metal materials to modern non-metallic materials, and their functions and uses are becoming increasingly rich and diverse.

[0003] However, despite the dazzling array of zipper tooth structures on the market, there are some common defects that cannot be ignored. Although the tooth structure of a traditional zipper can achieve basic meshing functions, the teeth are prone to fall off or dislocation when subjected to external forces, causing the zipper to be unable to be used normally, which brings great inconvenience to the user. Moreover, in daily life, the zippers of certain items are opened and closed repeatedly at a high frequency, but the existing zippers have low strength, are easily worn and torn, have poor durability, and are quite troublesome to replace. For example, in the prior art, a Chinese patent with publication number CN202950113U discloses an explosion-proof zipper with a guide plate, which also mentions that existing zippers have defects such as easy damage and tearing, easy to explode, and not durable. In addition, the design of some tooth structures is too complicated, which not only increases manufacturing costs, but also reduces production efficiency.

[0004] Therefore, there is an urgent need for a chain tooth structure and a zipper with explosion-proof teeth to solve the above technical problems. Summary of the invention

[0005] In response to the problems in the related technology, the utility model proposes a chain tooth structure and a zipper with explosion-proof teeth to overcome the above-mentioned technical problems existing in the existing related technology. In the utility model, the setting of the second meshing groove, the side teeth, the first meshing groove and the special-shaped limiting groove is conducive to limiting the tooth head to be firmly embedded in the special-shaped limiting groove; moreover, through the dual effects of the second meshing groove, the side teeth and the first meshing groove, the chain tooth body has a stronger locking force when meshing, effectively preventing the chain teeth from falling off or dislocating.

[0006] The technical solution of the utility model is implemented as follows: a chain tooth structure of explosion-proof teeth, comprising a first chain belt and a second chain belt; each of the chain belts comprises a fabric core, and a plurality of chain tooth bodies arranged on the fabric core in sequence and at intervals; the chain tooth bodies of the first chain belt and the chain tooth bodies on the second chain belt are alternately meshed with each other;

[0007] The cloth core is used to wrap and fix the edges of each of the chain belts to prevent the threads at the edges from unraveling;

[0008] The chain element body comprises a tooth head, a tooth neck and a tooth body connected in sequence, wherein the tooth head is biased toward one side of the tooth body; each of the chain element bodies is connected to the cloth core through the tooth body; the tooth head comprises a first meshing portion and a second meshing portion; the tooth neck comprises a first meshing groove and a second meshing groove; one end of the first meshing groove is connected to the first meshing portion, and the other end of the first meshing groove is provided with a side tooth, and the side tooth protrudes in a direction away from the tooth body; the side tooth is located at the front side of the cloth core; the second meshing portion is connected to the second meshing groove;

[0009] On the same chain belt, the second meshing groove of one chain tooth body is combined with the side teeth and the first meshing groove of the next chain tooth body to form a special-shaped limiting groove; the special-shaped limiting groove is matched and connected with the corresponding tooth head on the other chain belt; the special-shaped limiting groove limits the upward and downward movement of the tooth head;

[0010] The arrangement of the second meshing groove, the side teeth, the first meshing groove and the special-shaped limiting groove is conducive to limiting the tooth head to be stably embedded in the special-shaped limiting groove; wherein, the second meshing groove is used to limit the deviation and fall-off of the second meshing part, and the side teeth and the first meshing groove are used to limit the deviation and fall-off of the first meshing part. Furthermore, a reinforcement part is provided at the bottom of the second meshing groove, and when the special-shaped limiting groove is matched and connected with the corresponding tooth head on another chain belt, the bottom of the tooth head is pressed against the reinforcement part;

[0011] Furthermore, on the same chain element body, the tooth body includes an upper tooth body and a lower tooth body, the tooth head and the tooth neck are connected to the upper tooth body; the lower tooth body covers the upper tooth body and the tooth neck;

[0012] Preferably, the lower tooth body is in a rectangular parallelepiped shape or a cube shape; the reinforcement portion is a platform structure of the lower tooth body exposed at the second engagement groove;

[0013] The provision of the reinforcement part is beneficial to improving the hardness of the tooth body. Even if the tooth body is hit by a sharp object, the provision of the reinforcement part prevents the tooth head from being deformed by the impact, thereby further preventing tooth bursting.

[0014] Furthermore, the side of the side tooth close to the first meshing portion is an arc surface; the arc surface is connected with the first meshing groove to form a U-shaped groove; wherein the U-shaped groove limits the left and right movement of the first meshing portion of the corresponding chain tooth body on the other chain belt.

[0015] Further, the side of the side teeth away from the first meshing portion is a plane; the plane abuts against the front side of the cloth core;

[0016] In the utility model, since the tooth head is biased toward one side of the tooth body, the weight distribution of the chain tooth body is uneven, and the design of the plane makes the contact area between the side tooth and the cloth core larger, which is beneficial to increase the force-bearing area. Under the same force, the larger the force-bearing area, the smaller the pressure per unit area, which helps to reduce local stress concentration and reduce the risk of damage to the side teeth; at the same time, the design of the plane can also increase the stability between the contact surface between the side teeth and the cloth core.

[0017] Furthermore, the tooth body includes a mounting portion connected to the cloth core, and the mounting portion includes a mounting hole for the cloth core to pass through; the height d of the side teeth covering the tooth body is not greater than the diameter of the mounting hole.

[0018] Furthermore, the first meshing portion and the second meshing portion are symmetrically arranged; and the top of the side teeth does not exceed the top of the first meshing portion.

[0019] Furthermore, the head of the tooth head is a curved surface, and the first meshing portion is connected to the second meshing portion through the curved surface.

[0020] A zipper with explosion-proof teeth comprises the above-mentioned chain tooth structure with explosion-proof teeth; wherein the first chain belt and the second chain belt are closed or opened by reciprocating sliding of a zipper head.

[0021] Further, the second engagement groove is provided with a plurality of curved surfaces matching the tooth head;

[0022] Furthermore, when the special-shaped limiting groove is matched and connected with the corresponding tooth head on the other chain belt, a gap is left between the side teeth and the corresponding tooth head on the other chain belt to facilitate smooth sliding of the zipper head.
