Preferably, two sets of sealing components are uniformly distributed on the sealing base along its thickness direction, two first sealing protrusions are provided on the right belt body, and a first sealing protrusion is formed between two adjacent first sealing protrusions. Two sealing grooves, two first sealing grooves are correspondingly formed on the left belt body by three evenly distributed second sealing protrusions, when the zipper is chained, the two first sealing protrusions are clamped in In the first sealing groove, the second sealing protrusion located in the middle is clamped in the second sealing groove.

Preferably, two groups of sealing components are uniformly distributed on the sealing base along the thickness direction thereof, and a first sealing protrusion and two second sealing protrusions are sequentially provided on the left belt body from top to bottom, so The right belt body is provided with two corresponding second sealing protrusions and one first sealing protrusion in sequence from top to bottom.

Preferably, the first sealing protrusion is evenly provided with a plurality of protrusions to prevent the zipper from being axially displaced, and the first sealing groove is provided with a clamping groove that cooperates with each of the protrusions.

Preferably, the cross section of the first sealing protrusion is spherical.

Preferably, when the zipper is closed, the upper and lower ends of the sealing bases on the left belt body and the right belt body are on the same horizontal plane.

By adopting the foregoing technical scheme, the beneficial effects of the present invention are:

The invention improves the sealing structure. By arranging multiple sets of sealing components between the left belt body and the right belt body, the first sealing protrusions, the first sealing grooves and the second sealing protrusions with different shapes in the thickness direction of the zipper are formed. The two sealing forms of the sealing protrusion and the second sealing groove cooperate with each other, and the two sealing forms cooperate and complement each other. Compared with the multi-group replication and the same form of sealing structure, the structure can have stronger structural stability. The sealing assembly can bear greater axial force, and has a stronger function of preventing the sliding and dislocation leading to the failure of the cooperation between the sealing assemblies.

Detailed ways

The embodiments of the present invention will be described in detail below with reference to specific examples, so as to fully understand and implement the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects.

Example 1

Referring to FIG. 1, a waterproof and airtight zipper includes a left belt body 1, a right belt body 2, and a zipper puller (not shown in the figure) provided on the left belt body 1 and the right belt body 2. The left belt body 1 and the The right belt body 2 is made of waterproof and airtight material, and the adjacent side of the left belt body 1 and the right belt body 2 is provided with a sealing base 3, and the sealing base 3 is uniformly distributed along its thickness direction. Two sets of sealing assemblies 4, each of which includes a first sealing protrusion 41 and a second sealing protrusion 42; when the zipper is connected, two adjacent second sealing protrusions 42 are formed for clamping In the first sealing groove 51 of the first sealing protrusion 41, a second sealing groove 52 for clamping the second sealing protrusion 42 is formed between two adjacent first sealing protrusions 41;

In this embodiment, two sets of sealing assemblies 4 are evenly distributed on the sealing base 3 along its thickness direction. A second sealing groove 52 is formed between a sealing protrusion 41 , and two first sealing grooves 51 are correspondingly formed on the left belt body 1 by the three evenly distributed second sealing protrusions 42 . When closed, the two first sealing protrusions 41 are clamped in the first sealing groove 51 , and the second sealing protrusion 42 located in the middle is clamped in the second sealing groove 52 . Specifically, the first sealing protrusion 41 is provided on the right belt body 2, the second sealing protrusion 42 is provided on the left belt body 1, and the sealing assembly 4 on the left belt body 1 and the right belt body 2 adopts Different structural designs;

Wherein, when the zipper is closed, the upper and lower ends of the sealing base 3 on the left belt body 1 and the right belt body 2 are on the same horizontal plane, that is, when the zipper is closed, the left belt body 1 and the right belt body 2 After the sealing base 3 and the sealing assembly 4 between them are matched, the upper and lower ends have a flat structure; this structure can reduce the matching gap between the sealing components, reduce the probability of the medium entering from the gap, and also reduce the impact of The situation that the gap becomes larger due to the action of foreign objects occurs;

Specifically, the cross-section of the first sealing protrusion 41 is spherical; correspondingly, the first sealing groove 51 is also a spherical groove-shaped structure; and the second sealing protrusion 42 is angular It has a convex structure, and the thickness of the end is slightly larger than that of the root. The second sealing protrusion 42 is embedded between the two first sealing protrusions 41, and the three second sealing protrusions 42 are connected with the two first sealing protrusions. The zippers 41 are constrained to each other after being chained together, the structure is stable, and the spherical cross-sectional structure is more conducive to the chaining of the zipper.

Embodiment 2
