Description

Technical Field

[0001] This invention belongs to the field of snap fastener technology, specifically relating to a push-pull snap fastener. Background Technology

[0002] Snap fasteners are a type of button, commonly known as snap buttons, spring buttons, or sewn buttons, and are mostly used to fasten clothing.

[0003] Some technical solutions for snap fasteners have also emerged in the prior art, such as a Chinese patent with publication number CN107668845B, which discloses a snap fastener in which the first component has a snap fastener plate structure with an annular groove. With the guidance of the inner wall of the annular groove, the snap foot splits open and folds upward to form a retaining part, which is matched and embedded in the annular groove and is limited by the snap hole, thereby achieving a stable and firm fastening effect.

[0004] However, like other ordinary snap fasteners, this patent requires special tools or certain skills to install and replace, and it also damages the clothing. This is not convenient for elderly people who like to mend clothes, and it does not allow for quick and easy replacement of the snap fasteners. Summary of the Invention

[0005] The purpose of this invention is to provide a push-pull snap fastener in order to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A push-pull snap fastener includes a male snap and a female snap. Pushing the male snap into place aligns it with the female snap and locks it in place. Pulling the male snap unlocks it. Both the male and female snaps have clamping parts.

[0008] The clamping part includes a first clamping plate and a second clamping plate with a gap between them, and the ends of the first clamping plate and the second clamping plate are connected together.

[0009] Insert the edge of the garment into the gap between clamp plate number one and clamp plate number two of the clamping part, so that clamp plate number one and clamp plate number two clamp the garment, thereby fixing the male and female buttons to the garment.

[0010] Preferably, the second clamping plate has several mounting grooves on its plane facing the first clamping plate, and the mounting grooves have protrusions to improve the anti-slip performance of the clamping part, with the surface of the protrusions exposed in the mounting grooves.

[0011] Preferably, the bump has a plurality of protrusions facing different directions.

[0012] Preferably, the bump is made of magnetic material and the first clamp is made of iron.

[0013] Preferably, the female buckle includes a main body and two elastic elements located inside the main body;

[0014] The main body is provided with a through hole, and a pressing member connected to the elastic element is provided at the through hole. The pressing member squeezes the elastic element to deform the elastic element so that the male buckle can be smoothly separated from the female buckle.

[0015] Preferably, both the No. 1 clamping plate and the No. 2 clamping plate are provided with threaded holes, and bolts that fasten the No. 1 clamping plate and the No. 2 clamping plate together are threadedly connected to the threaded holes.

[0016] Preferably, the first clamping plate has a cavity, and both the male and female buckles have an installation channel that communicates with the cavity of the corresponding first clamping plate. An extrusion column is provided in the installation channel, and a movable plate is connected to the extrusion column by an elastic sheet. The movable plate is provided with several inserts for enhancing the stability of the clamping part.

[0017] The first clamping plate is provided with a through hole communicating with the cavity, and the second clamping plate is provided with a slot for limiting the position of the insert.

[0018] Preferably, the slot surface has burrs so that the insert is difficult to detach on its own after entering the slot.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention adds a clamping part to the snap fastener, making it easy to clamp onto clothing, replacing the traditional snap fastener installation method that requires drilling holes in the clothing. This not only protects the clothing but also improves the ease of installation of the snap fastener.

[0021] 2. The present invention increases the contact area between the snap fastener and the clothing by having the clamping part contact the clothing, thereby reducing the pulling on the clothing during the use of the snap fastener and providing further protection for the clothing.

[0022] 3. By modifying the female snap fastener of the snap fastener, the male snap fastener can be easily installed and removed, which not only makes the snap fastener have a greater locking effect, but also makes the snap fastener easier to undo. Attached Figure Description

[0029] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0030] Example 1

[0031] like Figure 1-5 As shown, a push-pull snap fastener includes a male snap 1 and a female snap 2. When the male snap 1 and the female snap 2 are pressed together, they form a locking structure.

[0032] Both the male buckle 1 and the female buckle 2 have a clamping part, which includes a first clamping plate 3 and a second clamping plate 4 with a gap between them. The ends of the first clamping plate 3 and the second clamping plate 4 are fixedly connected together.

[0033] It should be noted that the first clamp 3 and the second clamp 4 are elastic. When using, widen the gap between the first clamp 3 and the second clamp 4 by hand, and insert the edge of the garment parallel to the gap between the clamping parts. Then release the clamping part. Under the elastic force, the first clamp 3 and the second clamp 4 move closer together and clamp the garment, thus fixing the male buckle 1 and the female buckle 2 to different garments. Then fasten the male buckle 1 and the female buckle 2 together for use. To disassemble, simply widen the gap between the first clamp 3 and the second clamp 4 and remove the edge of the garment.

[0034] Furthermore, the second clamping plate 4 is provided with several mounting grooves 5 on the plane facing the first clamping plate 3. The mounting grooves 5 are provided with protrusions 6 to improve the anti-slip performance of the clamping part, and the surface of the protrusions 6 is exposed in the mounting grooves 5.

[0035] The protrusion 6 has several protrusions 7 facing different directions.

[0036] The bump 6 is made of magnetic material, and the first clamp 3 is made of iron.

[0037] In the above embodiment, when the first clamping plate 3 and the second clamping plate 4 clamp the clothing in the middle, the protrusion 6 comes into contact with the clothing, and under the action of the squeezing force, the protrusion 6 causes the clothing to deform under the squeezing force, thereby ensuring that the protrusion 6 is in full contact with the clothing. Under the action of the protrusion 7, the protrusion 6 is difficult to move on the surface of the clothing, thereby giving the second clamping plate 4 and the entire clamping part good stability, and the snap fastener will not shift significantly or easily during use.

[0038] At the same time, the protrusion 6 and the first clamping plate 3 have a magnetic attraction, which enhances the clamping force of the first clamping plate 3 and the second clamping plate 4, making the snap fastener less likely to detach from the clothing.

[0039] Furthermore, the female buckle 2 includes a main body 8 and two elastic elements 9 located inside the main body 8. When the convex ball on the male buckle 1 enters the main body 8, it is clamped by the elastic elements 9.

[0040] The main body 8 has a through hole, and a pressing member 10 connected to the elastic member 9 is provided at the through hole. The pressing member 10 compresses the elastic member 9, causing it to deform, so that the male buckle 1 can easily enter the female buckle 2. When the pressing member 10 is released, the elastic member 9 returns to its original shape, clamping the male buckle 1. To unfasten the snap fastener, simply push the pressing member 10 again to move the elastic member 9 away from the male buckle 1, allowing the male buckle 1 to separate smoothly from the female buckle 2.

[0041] Furthermore, both the first clamp plate 3 and the second clamp plate 4 are provided with threaded holes 11, and bolts 12 are threadedly connected to the threaded holes 11 to fasten the first clamp plate 3 and the second clamp plate 4 together. By tightening the bolts 12, the first clamp plate 3 and the second clamp plate 4 can fit more tightly together, further improving the stability of the snap fastener on the clothing.

[0042] Example 2

[0043] Unlike Embodiment 1, the first clamping plate 3 has a cavity 13. Both the male buckle 1 and the female buckle 2 have an installation channel that communicates with the cavity 13 of the corresponding first clamping plate 3. An extrusion column 14 is movably installed in the installation channel. An elastic sheet is fixedly connected to the extrusion column 14. A movable plate 15 is fixedly connected to the extrusion column 14 through the elastic sheet. Several inserts 16 for strengthening the stability of the clamping part are hinged on the movable plate 15.

[0044] The first clamping plate 3 is provided with a through hole 17 that communicates with the cavity 13 and leads to the outside. The second clamping plate 4 is provided with a slot 18 for limiting the insertion piece 16.

[0045] The groove surface of slot 18 has burrs so that the insert 16 is difficult to detach on its own after entering slot 18. The burrs increase the friction coefficient of the groove surface, making it difficult for the insert 16 to detach from the second clamp 4 during use.

[0046] It should be noted that when the male buckle 1 is pressed into the female buckle 2, the two pressing posts 14 press against each other, causing the pressing posts 14 to enter the male buckle 1 or the female buckle 2. The pressing posts 14, through the deformation of the elastic sheet, can drive the moving plate 15, which is perpendicular to it, to move within the cavity 13 of the first clamping plate 3. When the moving plate 15 moves, it drives the insert 16 to move. The end of the insert 16 is arc-shaped, and the end of the insert 16 moves downward at the through hole 17 of the first clamping plate 3. Limited by the through hole 17, the insert 16 rotates and finally inserts into the slot 18 at an angle perpendicular to the first clamping plate 3. The end of the insert 16 has a pointed tip. During the rotation, the insert 16 inserts into and passes through the clothing, finally contacting the second clamping plate 4 and passing through the middle of the clothing, making the clamping part more stable.

[0047] During disassembly, pliers are used to pull and squeeze the column 14 outward, thereby causing the moving plate 15 to move the insert 16 and pull the insert 16 out of the slot 18.

[0048] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
