Abstract
Description
Technical Field
[0001] The present invention relates to the field of zippers, and more particularly to a snap - type opening zipper. Background Art
[0003] In the structure of traditional opening components (pins / boxes), the slider is first pulled to the box, then the pin is inserted into the slider cavity and reaches the bottom of the box. One hand holds the pin for the insertion action, while the other hand holds the pull tab of the slider for closing and opening the zipper. If opening, it is the reverse operation, and two hands are also required. This is the traditional common practice. Although there are magnetic opening structures on the market, they are costly and only convenient for single - hand operation. Summary of the Invention
[0004] The present invention provides a snap - type opening zipper, aiming to solve the disadvantages of the prior art, enabling users to operate the opening zipper quickly, stably, accurately, simply and rapidly.
[0005] The technical solution adopted by the present invention to solve its technical problems is as follows:
[0006] A snap - type opening zipper, characterized in that:
[0007] The box extends a tail backward, and the tail extends an elastic crossbar to the right. The crossbar has a convex portion.
[0008] The rear end of the pin extends an elastic pin tail, and the pin tail has a concave portion.
[0009] The box is fixed on the left zipper with a left chain tape. The slider is combined with the left chain tape and abuts above the box. The pin is fixed on the right zipper with a right chain tape.
[0010] When the box and the pin are combined, the above - mentioned convex portion is stuck in the concave portion, forming a buckling structure where the box blocks the pin.
[0011] The crossbar extends a convex portion downward, and the pin tail has an upward concave portion. The convex portion extended downward by the crossbar is stuck in the upward concave portion of the pin tail to form a longitudinal buckling structure.
[0012] The pin extends an upper - layer elastic rod and a lower - layer elastic rod. The box is provided with an upper - layer tail and a lower - layer tail. The upper - layer tail is provided with a downward convex portion to correspond to the upward concave portion of the upper - layer elastic rod, and the lower - layer tail is provided with an upward convex portion to correspond to the downward concave portion of the lower - layer elastic rod.
[0013] The crossbar extends a convex portion to the right, and the pin tail has a corresponding left - facing concave portion. The convex portion extended to the right by the crossbar is stuck in the corresponding left - facing concave portion of the pin tail to form a transverse buckling structure.
[0014] The cross bar is an elastic structural bar with an arc extending backward from the lower blocking part. The concave part of the structural bar faces forward, and a convex part extends rightward from the right end of the structural bar.
[0015] The surface of the end of the tail of the cutting tip adjacent to the concave part and facing the convex part is provided with an inclined surface.
[0016] The cutting tip and the tail of the cutting tip are integrally injection-molded using elastic plastic; or, when the cutting tip is a metal die-casting, the cutting tip is additionally provided with a cutting hole, and the tail of the cutting tip formed by plastic injection molding is fixed by dotting and inserting; or, the tail of the cutting tip is injection-molded with rubber coating on the cutting tip.
[0017] The beneficial effects of the present invention are as follows:
[0018] The present invention utilizes the concave part at the end of the cutting tip and the convex part at the tail of the lower blocking block to perform a "buckling and clamping" function with a concave-convex structure. It is injection-molded using plastic such as POM, and utilizes the elasticity of the plastic to perform a bouncing buckling or bouncing out "cutting and clamping" function for a single-handed operation to insert the cutting tip through the inner cavity of the pull head and through the lower blocking block until the concave part and the convex part are buckled and clamped as a "brake and stability" positioning. Ensure that the left and right chain tooth positions are at the correct tooth positions to be engaged, and then hold the pull tab with one hand to engage the teeth and start pulling or separate the teeth and pull out the cutting tip to separate. The operation of the open zipper can be fast, stable, accurate, simple and fast. Description of the Drawings

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0027] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as shown in Embodiment 1:
[0028] At the left end of the upper layer of the lower stop block 1, an upper layer tail 11 extends backward (
back
[0029] The lower stop block 1, the upper layer tail 11, the cross bar 13, the convex portion 14, and the lower layer tail 12 are integrally injection molded with elastic plastic. When the lower stop block 1 is a metal die casting, the upper layer tail 11 is provided with a plug hole for the cross bar 13 formed by plastic injection molding to be fixed by dotting and inserting, or the cross bar 13 is formed by overmolding on the lower stop block 1 so that the cross bar 13 has elasticity.
[0030] At the rear end of the plug 2, an elastic plug tail 21 extends backward. The plug tail 21 has an upward concave portion 23 and a terminal protrusion 22 adjacent to the concave portion 23. The upper surface of the terminal protrusion 22 of the plug tail 21 is provided with an inclined surface 221 facing obliquely upward.
[0031] The plug 2 and the plug tail 21 are integrally injection molded with elastic plastic. When the plug 2 is a metal die casting, the plug 2 is provided with a plug hole for the plug tail 21 formed by plastic injection molding to be fixed by dotting and inserting, or the plug tail 21 is formed by overmolding on the plug 2 so that the plug tail 21 has elasticity.
[0032] The lower stop block 1 is sewn and fixed on the left zipper cloth 41 (it can also be on the box body), and the left chain belt 51 of the left zipper is also sewn and fixed on the left zipper cloth 41.
[0033] The slider 3 is combined with the left tape 51 and is positioned above the lower stop 1.
[0034] The pin 2 is sewn and fixed on the cloth 42 of the right zipper (it can also be on the lid of the box), and the right tape 52 of the right zipper is also sewn and fixed on the cloth 42 of the right zipper.
[0035] When in use:
[0036] Insert the pin 2 into the slider cavity of the slider 3 and reach the bottom of the lower stop 1. Continuing to insert, the end protrusion 22 of the tail 21 of the pin will press against the protrusion 14 extending downward from the cross bar 13 of the lower stop 1. Since the tail 21 of the pin and the cross bar 13 are elastic, they will deform. The tail 21 of the pin moves downward, and the cross bar 13 moves upward. After the end protrusion 22 passes through the protrusion 14, the elastic deformation of the tail 21 of the pin and the cross bar 13 returns to its original position, that is, it bounces and latches. The protrusion 14 is stuck in the concave portion 23 of the tail 21 of the pin, and the lower stop 1 blocks the pin 22, so the pin 2 cannot be inserted further.
[0037] In this way, the concave portion 23 of the tail 21 of the pin and the protrusion 14 of the cross bar 13 form a "latching" function with the concave-convex structure, forming a "lateral pin latching", and the pin 2 and the lower stop 1 are relatively clamped and fixed to form a positioning. At this time, the left and right chain teeth are in the correct teeth positions to be joined, and the left tape 61 and the right tape 62 both enter the slider 3.
[0038] Then, hold the pull tab of the slider 3 with one hand and perform the teeth joining and pulling action. Since the pin 2 and the lower stop 1 are relatively clamped and fixed, they will not separate. Pulling the slider can join the left tape 51 and the right tape 52.
[0039] When it needs to be separated, as long as the slider 3 is pulled downward to separate the teeth, the slider 3 presses against the lower stop 1, and the elastic tail 21 of the pin is bent downward, the protrusion 14 leaves the concave portion 23, and the pin 2 returns to its original position, that is, it bounces out. Then pull the pin 2 forward to separate the pin 2 and the lower stop 1.
[0040] Operating the open zipper in this way can be fast, stable, accurate and simple and fast.
[0041] The design of the inclined surface 221 of the end protrusion 22 makes it easier for the tail 21 of the pin to deform downward and pass through the protrusion 14 when the inclined surface 221 presses against the protrusion 14.
[0042] In other embodiments, the pin extends out the upper elastic rod and the lower elastic rod, and the lower stop is provided with an upper tail and a lower tail. The upper tail is provided with a downward protrusion to correspond to the upward concave portion of the upper elastic rod, and the lower tail is provided with an upward protrusion to correspond to the downward concave portion of the lower elastic rod. That is, the pin and the lower stop can also be designed with upper and lower double concave portions and double protrusions to form an upper and lower double concave-convex blocking structure.
[0043] Such asFigure 5 Example 2 shown:
[0044] In addition, the lower stop 2 may also extend backward in an arc shape (inverted The elastic structure rod 15 of the structure rod 15 is of the shape of a steel plate, the concave portion of the structure rod 15 faces forward, and the right end of the structure rod 15 extends a convex portion 16 to the right.
[0045] The rear end of the skewer 2 extends backward to form an elastic skewer tail 21', which has a leftward recess 23' and a terminal protrusion 22' adjacent to the recess 23'. The upper surface of the terminal protrusion 22' of the skewer tail 21' is provided with a slope 221' facing left and rearward.
[0046] When using:
[0047] The skewer 2 is inserted into the slider cavity of the slider 3 and reaches the bottom of the lower block 1. If the skewer 2 is inserted continuously, the terminal protrusion 22' of the skewer tail 21' of the skewer 2 will press against the protrusion 16 extending to the right from the right end of the structure rod 15 of the lower block 1. Since the skewer tail 21' and the structure rod 15 are elastic, they will deform. The skewer tail 21' moves to the right and the structure rod 15 moves to the left. After the terminal protrusion 22' passes through the protrusion 16, the skewer tail 21' and the structure rod 15 are elastically deformed and reset, i.e., they bounce and snap together. The protrusion 16 is stuck in the concave portion 23' of the skewer tail 21', and the lower block 1 blocks the skewer 22, and the skewer 2 can no longer be inserted.
[0048] In this way, the concave portion 23' of the tail portion 21' of the skewer and the convex portion 16 of the rod 15 form a "buckle" function with a concave-convex structure, forming a "longitudinal skewer buckle", and the skewer 2 and the lower stopper 1 are relatively clamped and fixed to form a positioning. At this time, the left and right chain teeth are in the correct tooth position to be engaged, and the left chain belt 61 and the right chain belt 62 both enter the slider 3
[0049] Then, the pull tab of the slider 3 is held with one hand to engage the teeth and start pulling. Since the pin 2 and the lower stopper 1 are relatively fixed by clamping, they will not separate. By pulling the slider, the left chain belt 51 and the right chain belt 52 can be combined.
[0050] When separation is required, the pull head 3 is pulled downward to separate the teeth, the pull head 3 presses against the lower stopper 1, the elastic structure rod 15 is pressed downward or leftward, the protrusion 16 leaves the recess 23', the skewer 2 is reset, that is, it bounces out, and then the skewer 2 is pulled forward to separate the skewer 2 and the lower stopper 1.
[0051] This way of operating the zipper opening can be fast, stable, accurate, simple and quick.
[0052] The design of the inclined surface 221 ′ of the terminal protrusion 22 ′ makes it easier for the skewer tail 21 ′ to deform rightward and pass through the protrusion 16 when the inclined surface 221 ′ presses against the protrusion 16 .
[0053] The present invention is an essential auxiliary accessory that conforms to the principle of breaking up into parts for luggage, tents, ready-to-wear clothes and miscellaneous processed goods. It is very suitable for the design application of the mutual replacement of the box shells of luggage and the use of this open zipper for the inner lining cloth, and it is also possible to remove the left and right inner lining cloths and then combine them into a bag or a backpack. It achieves the best use of things and the smooth flow of goods.
