[0002] A zipper, also known as a lock, is a connector that can be repeatedly closed and opened and consists of two flexible, intermeshing parts. The round-tooth zipper is characterized by round teeth. This type of zipper is common in life and is also called an ordinary zipper.

[0003] The existing Chinese patent publication number is: CN203597493U, which discloses a zipper with an automatic stop device, which includes a slider for opening and closing the chain teeth and a stop device. The slider includes an upper wing, a lower wing and a connecting column. A through hole is provided on the upper wing. The stop device includes an abutment column and an elastic member. The abutment column includes a column, a first stopper, a second stopper and an abutment portion. The column passes through the through hole and is arranged on the upper wing. The first stopper is detachably arranged at one end of the column and exposed on the surface of the upper wing facing away from the lower wing, and the second stopper is arranged between the first stopper and the abutment portion. The elastic member abuts between the upper wing and the second stopper. The abutment portion is arranged at one end of the column close to the chain teeth, and the size of the abutment portion head matches the gap between two adjacent chain teeth. Compared with the prior art, after the slider stops, the abutment portion is clamped between two adjacent chain teeth. At this point, the pull head needs to exert a certain amount of external force before it can be pulled again to avoid being pulled randomly or accidentally.

[0004] The above-mentioned zipper also has the following problems when in use: the abutment portion of the above-mentioned zipper always abuts against the teeth under the action of the elastic member, so a certain amount of force needs to be applied when pulling the zipper, which makes the use of the zipper inconvenient, and in the process of pulling the zipper, the abutment portion is always in a state of obstructed movement, which affects the service life of the abutment portion.

[0005] Therefore, it is necessary to invent a round tooth zipper stop assembly to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a round-tooth zipper stop assembly to solve the problem that the abutment portion of the zipper proposed in the above-mentioned background technology always abuts against the teeth under the action of the elastic member, so that a certain amount of force needs to be applied when pulling the zipper, resulting in inconvenience in the use of the zipper, and in the process of pulling the zipper, the abutment portion is always in a state of obstructed movement, resulting in affecting the service life of the abutment portion.

[0007] In order to achieve the above-mentioned object, the utility model provides the following technical solutions: a round-tooth zipper stop assembly, comprising an upper wing plate, a guide column is fixedly connected between the upper wing plate and the lower wing plate, a cavity is formed between the upper wing plate and the lower wing plate, a mounting cover is fixedly connected to the top of the upper wing plate, and a pull tab is rotatably connected inside the mounting cover, and further comprising:

[0009] The limiting assembly comprises a connecting rod rotatably connected in the end of the abutting column, and the two ends of the connecting rod are rotatably connected to the limiting block, and the limiting block is slidably connected to the limiting groove through a spring, and the limiting groove is communicated with the movable groove.

[0010] Preferably, the abutment column passes through a through hole preset inside the upper wing plate, the diameter of which is slightly larger than the outer diameter of the abutment column, and the lower end of the abutment column extends to the inside of the cavity formed between the upper wing plate and the lower wing plate.

[0011] Preferably, the abutment plate is located inside the cavity formed between the upper wing plate and the lower wing plate, and an end of the abutment plate close to the guide column is fixedly connected with an inclined elastic sheet, and an end of the elastic sheet not connected to the abutment plate is in contact with and slidably connected to the inner wall of the cavity.

[0012] Preferably, there are two limit blocks, and the two limit blocks are symmetrically arranged with reference to the abutment column as the symmetry axis, and the outer walls of the two limit blocks are in contact with and slidably connected to the inner walls of the limit grooves.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-4 A round-tooth zipper stop assembly shown includes an upper wing plate 1, a guide column 3 is fixedly connected between the upper wing plate 1 and the lower wing plate 2, a cavity is formed between the upper wing plate 1 and the lower wing plate 2, and a mounting cover 4 is fixedly connected to the top of the upper wing plate 1, and a pull tab 5 is rotatably connected inside the mounting cover 4 to facilitate the pulling tab 5, and also includes:

[0027] The abutment assembly 6 has a movable groove 61 reserved inside the pull tab 5, and an abutment column 62 is movably connected inside the movable groove 61, and an abutment plate 63 is fixedly connected to the lower end of the abutment column 62, and an edge block 65 is fixedly connected to the bottom of the abutment plate 63, and the edge block 65 is engaged with the gap between the zipper teeth. In this way, the edge block 65 is engaged with the gap between the zipper teeth, thereby completing the limitation of the overall position of the zipper head at any time;

[0028] The limiting assembly 7 has a connecting rod 75 rotatably connected to the end of the abutment column 62, and the two ends of the connecting rod 75 are rotatably connected to the limiting block 71, and the limiting block 71 is slidably connected to the limiting groove 72 through a spring 74, and the limiting groove 72 is connected to the movable groove 61 to ensure stability when the pull tab 5 is moved.

[0029] The abutment column 62 passes through a through hole preset inside the upper wing plate 1, the diameter of which is slightly larger than the outer circle diameter of the abutment column 62, so as to ensure the stability of the subsequent up and down movement of the abutment column 62, and the lower end of the abutment column 62 extends to the inside of the cavity formed between the upper wing plate 1 and the lower wing plate 2, so that the zipper teeth can pass through the cavity conveniently.

[0030] The abutment plate 63 is located inside the cavity formed between the upper wing plate 1 and the lower wing plate 2, and an end portion of the abutment plate 63 close to the guide column 3 is fixedly connected with an inclined elastic sheet 64, and an end portion of the elastic sheet 64 not connected to the abutment plate 63 is in contact with and slidably connected to the inner wall of the cavity, so that when the zipper on one side is passed through the cavity between the upper and lower wing plates, the zipper on one side will not move out of position due to the shielding effect of the inclined elastic sheet 64 (that is, the zipper will not pass through the top of the abutment plate 63), and the elastic sheet 64 moves synchronously with the abutment plate 63 when it is lifted and is deformed by the force, and is reset when the external force is lost, which facilitates the up and down movement of the abutment column 62.

[0031] There are two limit blocks 71 , and the two limit blocks 71 are symmetrically arranged with reference to the abutting column 62 as the symmetry axis, and the outer walls of the two limit blocks 71 are in contact with and slidably connected to the inner walls of the limit grooves 72 .

[0032] The inner wall of the limiting groove 72 is fixedly connected to a limiting rod 73 , and the limiting rod 73 passes through the limiting block 71 slidably connected inside the limiting groove 72 and is slidably connected to the limiting block 71 , ensuring the stability of the limiting block 71 during the movement of the pull tab 5 and the movement of the abutment column 62 .

[0033] The two ends of the spring 74 are fixedly connected to the outer wall of the limit block 71 and the inner wall of the limit groove 72 respectively, and the spring 74 is movably sleeved on the outer ring of the limit rod 73. When the pull tab 5 is lifted, the abutment column 62 moves and synchronously causes the limit block 71 to move inside the limit groove 72, and at the same time facilitates the subsequent reset movement of the limit block 71 and the abutment column 62.

[0034] The connecting rod 75 passes through the top of the abutment column 62, and the connecting rod 75 and the internal through-hole of the abutment column 62 are rotatably connected through a bearing, so that the abutment column 62, the connecting rod 75 and the limit block 71 are all rotatably connected, and the lifting movement of the abutment column 62 will not be affected during the process of moving the pull tab 5.

[0035] Working principle: When using a round-tooth zipper stop assembly, the pull tab 5 can be first moved, and the pull tab 5 tilts. At this time, the abutment column 62 movably connected inside the pull tab 5 is lifted synchronously, and then the edge block 65 fixedly connected to the lower end of the abutment plate 63 moves away from the gap between the zipper teeth. While the pull tab 5 is moved, the zipper head can also be pulled smoothly.

[0036] When it is necessary to limit the position of the zipper head, the pull tab 5 is released. At this time, the elastic sheet 64 fixedly connected to the side of the abutment plate 63 loses the effect of external tension, and then the elastic sheet 64 drives the abutment plate 63 to perform a reset movement, thereby driving the edge block 65 to engage with the gap between the zipper teeth, thereby completing the limitation of the zipper head position. At the same time, under the thrust of the reset force of the spring 74, the limit block 71 returns to its initial position, thereby making the abutment column 62 in a vertical state. At the same time, this also ensures that the abutment plate 63 and the edge block 65 are engaged with the gap between the zipper teeth to the greatest extent, thereby ensuring the stability of the zipper head limit.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
