Example 1

Referring to fig. 1, 2, 4 and 5, the present embodiment provides a quick zipper structure, including a left base 1 and a right base 2 with a plurality of mutually matched zipper teeth 3, and a slider 14 for controlling the zipper teeth 3 to be engaged or separated, the same as a general zipper, the bottom of the zipper is further provided with a lower stop portion, the bottom of the left base 1 is a pin, the bottom of the right base 2 is a slot, when the zipper is opened, the slider 14 is fixed on the right base 2, wherein the left base 1 and the right base 2 mainly play a role of connecting the zipper teeth 3, and the material can be common cloth, leather, and the like without limitation; the right base part 2 is provided with a right upper stop part 4 and a separation part 5 positioned above the right upper stop part 4, the left base part 1 is provided with a left upper stop part, the left upper stop part comprises a limit card 8 and a base 7 which are arranged in an up-down relationship, the limit card 8 has elasticity and rigidity and can be prepared by beryllium copper, spring steel or high polymer materials, the base 7 is abutted with the right upper stop part 4 and has the same thickness with the right upper stop part 4, wherein the width of the base 7 and the right upper stop part 4 can be the same as the width of the zipper teeth 3, the width of the upper end of the limit card 8 is smaller than the width of the lower end, the upper end extends to the outer side of the base 7, the vertical line of the end point of the upper end is also positioned at the outer side of the zipper teeth 3, the edge of the lower end of the limit card 8 is overlapped with the base 7 or positioned at the inner side of the base 7, namely, the zipper is characterized in that through grooves 11 for clamping the zipper teeth 3 are formed in two sides of the slider 14, the through groove 11 in the right side of the slider 14 is the same as a common slider 14 and is only clamped with the zipper teeth 3 of the right base part 2, a limiting hole 12 matched with the limiting clamping piece 8 is formed above the through groove 11 in the left side of the slider 14 (namely the through groove 11 clamped with the zipper teeth 3 on the left base part 1), namely the through groove 11 is larger than the thickness of the base part and is the same as or slightly larger than the sum of the thicknesses of the base part and the limiting clamping piece 8, a side wall 13 is arranged on the part, located above the base 7, of the through groove 11, the limiting hole 12 is arranged on the side wall 13, the limiting clamping piece 8 enters or is separated from the limiting hole 12 along with the movement of the slider 14, and the. When the slider 14 reaches the separating portion 5, a stopper portion 6 may be provided above the separating portion 5 in order to prevent the slider 14 from slipping out from the upper end of the slide fastener, and the stopper portion 6 may extend to the outside of the separating portion 5 away from the left base portion 1, that is, the width of the stopper portion 6 is larger than the maximum width of the right through groove 11 of the slider 14, so that the slider 14 cannot pass over the stopper portion 6, and the upper right stopper portion 4, the separating portion 5, and the stopper portion 6 may be provided separately in order to improve the comfort of use of the slide fastener.

The working principle is as follows: when the zipper is closed, when the slider 14 is pulled to the top of the zipper, the upper end of the slider 14 contacts with the lower ends of the base 7 and the limiting clamping piece 8 firstly, at this time, along with the upward movement of the slider 14, the limiting clamping piece 8 is pressed, so that the upper end of the limiting clamping piece 8 is retracted (namely, is propped against the side wall 13), along with the continuous upward movement of the slider 14, the upper end of the limiting clamping piece 8 extends into the limiting hole 12, at this time, an obvious blocking feeling is generated, the zipper is stopped to be pulled, the limiting clamping piece 8 can effectively prevent the slider 14 from automatically moving downwards, namely, the zipper is always kept in a closed state, when the zipper needs to be opened, the slider 14 is continuously pulled upwards by slight force, at this time, the limiting clamping piece 8 is separated from the limiting hole 12, the slider 14 smoothly reaches the separating part 5, the locking force between the zipper teeth 3 is lost, the zipper is directly pulled towards, the zipper is rapidly opened, the use experience of the zipper is greatly improved, and after the zipper is pulled open, the bottom of the zipper can be automatically returned to the bottom of the zipper under the action of gravity to be attached to the lower portion of the zipper, the resetting effect is good, and the zipper is convenient to pull and close again.

In the process of closing the zip fastener, if the distance between upper left stop portion and the chain tooth 3 of left basal portion 1 top is too big, can lead to this department chain tooth 3 laminating not tight, the easy bullet is opened, and to this, this embodiment is in base 7 and spacing card 8 lower extreme are provided with and chain tooth 3 complex arc wall 9 for realize seamless transition between upper left stop portion and the chain tooth 3, promote the locking performance of zip fastener.

Example 2

Referring to fig. 1 to 6, in the present embodiment, a first arc-shaped surface and a second arc-shaped surface are respectively disposed on two sides of the limit card 8, the first arc-shaped surface is located on one side of the limit card 8 close to the right base 2 and is bent toward the side far from the right base 2, the second arc-shaped surface is located on one side of the limit card 8 far from the right base 2 and is bent toward the side near the right base 2, the length of the first arc-shaped surface is smaller than that of the second arc-shaped surface, the connection strength between the limit card 8 and the base 7 is good, the limit card 8 has good elasticity, and the arc-shaped design enables the limit card 8 not to have a significant turning point, i.e., no significant stress concentration point, so as to prolong the service life of the limit card 8.

Further, the pull head 14 is provided with a spacing groove located above the through groove 11 near one side of the left base portion 1, the setting track of the spacing groove coincides with the through groove 11, the spacing groove is provided with a side wall 13 near one side of the left base portion 1, the other side is communicated with the through groove 11, the spacing hole 12 is arranged on the side wall 13 of the spacing groove, a partition board is arranged between the spacing groove and the through groove 11, the width of the partition board is smaller than the depth of the through groove 11, and a groove 10 matched with the partition board is arranged between the base 7 and the spacing card 8. Namely, when the slider 14 moves to the upper left stop part, the base part is positioned in the through groove 11, the groove 10 abuts against the partition plate, and the limiting clamping piece 8 is positioned in the limiting groove, so that the limiting clamping piece 8 can be effectively prevented from shaking up and down in the moving process of the slider 14 and being separated from the limiting hole 12 under the condition of non-artificial unlocking, and the locking capacity of the meshing state of the zipper is improved.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited thereto, the protection scope of the present invention is defined by the claims, and all structural changes equivalent to the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
