Description

Technical Field

[0001] The utility model relates to the technical field of zipper manufacturing, and more specifically, to an explosion-proof and airtight zipper puller. Background Art

[0002] Because a layer of sealing rubber is arranged above the sprocket teeth of the airtight zipper, when the rubber passes through the slider together with the sprocket teeth, the contact area between the rubber and the slider upper plate is large, the friction is large, and it is difficult to pull and close. If the distance between the slider upper plate and the slider lower plate is increased to improve this problem, the sprocket teeth will fall off the slider more easily, and the overall effect is not good. Based on this, the utility model proposes an explosion-proof airtight zipper slider. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies in the prior art and provide an explosion-proof airtight zipper puller.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: the utility model relates to an explosion-proof airtight zipper pull head, comprising a pull head upper plate and a pull head lower plate, the pull head upper plate is provided with a pull nose head, the pull nose head comprises a positive pull head or a reverse pull head, a centrally arranged support core is connected between the pull head upper plate and the pull head lower plate, the support core is provided with a first pressure tooth wing on the left side and a second pressure tooth wing on the right side;

[0005] When a forward pull head is provided on the upper plate of the slider, the tooth pressing surfaces of the first and second tooth pressing wings are both facing upward; when a reverse pull head is provided on the upper plate of the slider, the tooth pressing surfaces of the first and second tooth pressing wings are both facing downward.

[0006] The utility model is further configured as follows: the cross-sectional shapes of the first pressing tooth wing and the second pressing tooth wing are triangle, trapezoid or rectangle.

[0007] The utility model is further configured as follows: the first pressing tooth wing and the second pressing tooth wing are configured to be bilaterally symmetrical.

[0008] The utility model is further configured as follows: the first pressing tooth wing and the second pressing tooth wing are left-right asymmetrical.

[0009] In summary, the utility model has the following beneficial effects: the explosion-proof and airtight zipper pull head involved in the utility model increases the height of the support core and arranges tooth-pressing wings on both sides of the support core. This not only enables the chain teeth with rubber parts to pass through the pull head smoothly, but also plays a role in explosion-proofing the zipper. The overall function is complete and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
