Description

TECHNICAL FIELD

[0001] The utility model relates to a nylon opening wingless zipper belongs to zipper technical field. BACKGROUND

[0002] Zipper is a fastener consisting of two strips each having a row of metal or plastic teeth for joining the edges of an opening (such as a garment or bag) and having a slide to draw the two rows of teeth into interlocking position to close the opening. A chain attached to something (as an object being hoisted or dropped) to tighten, steady, or guide it. A zipper is composed of chain elements, sliders, upper and lower stops (front and rear codes) or locking elements, etc. Among them, the chain element is the key part, which directly determines the side pulling strength of the zipper. Generally, the zipper has two chain strips, each of which has a row of chain elements. The slider clamps the chain elements on both sides, and the slider slides through the pull rod to make the chain elements on both sides interlock or separate.

[0003] In the prior art, the lower stop (inserting strip and inserting block) at the lower end of the first cloth tape and the second cloth tape is provided with resin block wings connected with the lower stop on both sides, which increases the manufacturing difficulty and production cost. However, once the resin block wings are directly removed, the lower end of the inserting strip connecting part is more likely to be worn out during the process of inserting the inserting strip into the inserting square hole on the inserting block, which affects the use effect of the zipper and reduces the use frequency of the zipper. Therefore, the utility model provides a nylon opening wingless zipper to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] Based on the above background, the purpose of the utility model is to provide a nylon opening wingless zipper to solve the problems in the background art.

[0005] The utility model provides the following technical scheme:

[0007] Preferably, the first fabric strip is provided with a left chain tooth at one end near the second fabric strip, and the lower end of the left chain tooth is aligned with the upper end of the connector strip.

[0008] Preferably, the left end of the left chain tooth on the first fabric strip is provided with a left upper stop.

[0009] Preferably, the second fabric strip has a right chain tooth at one end near the first fabric strip, the top surface of the plug block has a guide block near the right chain tooth, the lower end of the right chain tooth is aligned with the upper end of the guide block, and the upper end of the right chain tooth on the second fabric strip has a right upper stop.

[0010] Preferably, the left and right chain teeth are engaged, and a sliding pull head is slidably connected to the right chain tooth, with a pull tab movably disposed on the pull head.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model discloses a nylon open-end wingless zipper. By removing the resin blocks at the wing positions on both sides of the insert strip and insert block, the amount of resin raw materials is reduced, thus lowering production costs. At the same time, an L-shaped reinforcing block is set on the left side of the insert strip, and the inner side of the L-shaped reinforcing block is bonded to the inner wall of the first and second recesses. When the insert strip is inserted into the insertion square hole on the insert block, the L-shaped reinforcing block slides in the sliding opening, avoiding direct friction between the shaping layer or the inner wall of the sliding opening of the first fabric tape during the insertion process. This prevents damage to the first recess at the lower end of the first fabric tape and the shaping layer at the first recess position, which would affect the insertion effect, and increases the number of uses of the zipper.

[0021] like Figs. 1-3 As shown, a nylon open-end wingless zipper includes a first fabric strip 1 and a second fabric strip 2. Both ends of the first fabric strip 1 and the second fabric strip 2 have a first notch 3. A shaping layer 4 is adhered to both ends and both surfaces of the first fabric strip 1 and the second fabric strip 2. The shaping layer 4 has a second notch 5 of the same specification as the first notch 3. The first notch 3 and the second notch 5 correspond to each other. An insert strip 6 is provided on the lower right side of the surface of the first fabric strip 1, and an L-shaped reinforcing block 7 is provided on the left side of the insert strip 6. The L-shaped reinforcing block 7 is bonded to the shaping layer 4. The inner side of the L-shaped reinforcing block 7 is bonded to the inner wall of the first recess 3 and the second recess 5. The lower left side of the surface of the second fabric tape 2 is provided with an insertion block 8. The insertion block 8 is bonded to the shaping layer 4. The insertion block 8 is provided with an insertion square hole 9. The left end face of the insertion block 8 is provided with a sliding opening 10. The sliding opening 10 communicates with the insertion square hole 9. The insertion block 8 is inserted into the insertion square hole 9. The L-shaped reinforcing block 7 is located in the sliding opening 10.

[0022] In the above technical solution, this utility model reduces resin raw materials and production costs by removing the resin blocks at the wing positions on both sides of the insert strip 6 and the insert block 8. At the same time, it sets an L-shaped reinforcing block 7 on the left side of the insert strip 6 and makes the inner side of the L-shaped reinforcing block 7 bonded to the inner wall of the first recess 3 and the second recess 5. When the insert strip 6 is inserted into the insertion square hole 9 on the insert block 8, the L-shaped reinforcing block 7 slides in the sliding opening 10, avoiding direct friction between the shaping layer 4 or the first fabric tape 1 and the inner wall of the sliding opening 10 during the insertion process. This prevents damage to the first recess 3 at the lower end of the first fabric tape 1 and the shaping layer 4 at the position of the first recess 3, which would affect the insertion effect and increase the number of times the zipper can be used.

[0023] In this utility model, the first fabric tape 1 is provided with a left chain tooth 11 at one end near the second fabric tape 2, the lower end of the left chain tooth 11 is aligned with the upper end of the insert strip 6, and the upper end of the left chain tooth 11 on the first fabric tape 1 is provided with a left upper stop 12.

[0024] In the above technical solution, by setting a left upper stop 12 at the upper end of the left chain tooth 11, the zipper can be prevented from slipping out of the left chain tooth 11 during use.

[0025] In this utility model, the second fabric strip 2 is provided with a right chain tooth 13 at one end near the first fabric strip 1, the top surface of the plug block 8 is provided with a guide block 14 near the right chain tooth 13, the lower end of the right chain tooth 13 is aligned with the upper end of the guide block 14, and the upper end of the right chain tooth 13 on the second fabric strip 2 is provided with a right upper stop 15.

[0026] In the above technical solution, by setting a right upper stop 15 at the upper end of the right chain tooth 13, the zipper can be prevented from slipping out of the right chain tooth 13 during use.

[0027] In this utility model, the left chain tooth 11 and the right chain tooth 13 are engaged, and a sliding pull head 16 is slidably connected to the right chain tooth 13, and a pull tab 17 is movably disposed on the pull head 16.

[0028] In the above technical solution, by setting the zipper head 16, the zipper head 16 can be pulled by the pull tab 17 connected to the zipper to make the left chain tooth 11 and the right chain tooth 13 engage or disengage.

[0029] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model.
