[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 The quick-release zipper bottom stop assembly shown in the figure comprises a cloth belt 1, a zipper tooth 2 is sewn on the side of the cloth belt 1, a block 3 is fixedly connected to the lower end of the cloth belt 1, and a plug hole 5 is provided inside the block 3, and an insert block 4 is movably installed inside the plug hole 5, and also comprises:

[0027] Insert component 6, a movable gap 61 is reserved inside the block 3, and the inner wall of the movable gap 61 is fixedly connected to a fixed rod 62, and the outer wall of the fixed rod 62 is slidably connected to a movable block 63, the movable block 63 is located inside the movable gap 61, the bottom wall of the movable block 63 is fixedly connected to a gasket 66, and the gasket 66 is fixedly connected to the end of an elastic plastic sheet 67, and the elastic plastic sheet 67 matches the buckling groove 8, and the buckling groove 8 is located inside the plug block 4.

[0028] The end of the plug block 4 is fixedly connected with a sharp corner 9, and the outer wall of the sharp corner 9 is smooth. Such a smooth sharp corner 9 makes it easier to open two symmetrical elastic plastic sheets 67, and the resistance is smaller and more labor-saving when the elastic plastic sheets 67 are opened. The plug block 4 and the block 3 form a lower stop.

[0029] The three sides of the insertion hole 5 are open, and the insertion hole 5 divides the block 3 into two independent upper and lower blocks.

[0030] There are two groups of four movable notches 61 in total, and two movable notches 61 form a group and are symmetrically arranged on one of the independent blocks of the block 3 , and the movable notches 61 are arranged to penetrate from top to bottom.

[0031] The movable block 63 is fixedly connected with the limiting blocks 64 on both sides, and the thickness of the limiting blocks 64 is less than that of the movable block 63. The limiting blocks 64 move inside the limiting grooves 65, and the limiting grooves 65 are connected with the movable notches 61 to ensure the stability of the movable block 63 during subsequent movement.

[0032] The elastic plastic sheet 67 is arched, and the symmetrical blocks on both sides of the elastic plastic sheet 67 are tilted and unfolded, and the appearance of the elastic plastic sheet 67 is an open trapezoid, so that the symmetrical blocks on both sides of the elastic plastic sheet 67 are easier to open, which facilitates the matching of the elastic plastic sheet 67 with the buckling groove 8;

[0033] There are two elastic plastic sheets 67, and the two elastic plastic sheets 67 are symmetrically arranged, and the two side ends of the two elastic plastic sheets 67 are respectively fixedly connected to the outside of the movable block 63 that is movably connected inside the block 3. The two elastic plastic sheets 67 are both located inside the socket 5, ensuring that the movable block 63 is driven to move when the two elastic plastic sheets 67 move, and the movable block 63 moves inside the movable notch 61, thereby ensuring the stability of the movement of the elastic plastic sheet 67.

[0034] A side wall of the buckling groove 8 away from the cloth belt 1 is provided with an arc surface 10, and the horizontal plane of the notch of the buckling groove 8 provided with the arc surface 10 is lower than the horizontal plane of the plug block 4, so as to facilitate the engagement of the elastic plastic sheet 67 with the buckling groove 8, and at the same time, ensure that the opening movement of the inclined blocks on both sides of the elastic plastic sheet 67 when squeezed will not be affected by the plug block 4 itself;

[0035] The remaining surfaces of the inner wall of the buckling groove 8 are all in an inclined state, so as to facilitate the movement of the entire elastic plastic sheet 67 in the gap between the insert block 4 and the block 3 after the body blocks on both sides of the elastic plastic sheet 67 are unfolded.

[0036] Working principle: When using a quick-release zipper bottom stop assembly, firstly, the head of the cloth tape 1 on one side of the plug block 4 is passed through the inside of the zipper head, and by matching the plug block 4 with the insertion hole 5, when the plug block 4 moves toward the insertion hole 5, the end of the sharp corner 9 of the plug block 4 moves between the two symmetrical elastic plastic sheets 67, and as the plug block 4 moves, the sharp corner 9 moves synchronously and then spreads the two elastic plastic sheets 67, causing the ends of the two sides of the elastic plastic sheet 67 to tilt and push the movable block 63 to move inside the movable notch 61, and after the plug block 4 completely moves into the insertion hole 5, the elastic plastic sheet 67 is subsequently elastically reset to match the buckling groove 8 reserved inside the plug block 4, thereby ensuring the stability of the insertion of the block 3 and the plug block 4, thus ensuring the stability of the installation of the plug block 4 and the block 3;

[0037] At the same time, when it is necessary to open the zipper, the plug block 4 is pulled outward, and the plug block 4 moves in the direction away from the insertion hole 5. At the same time, since the inner wall of the fastening groove 8 is provided with a curved surface 10, and the other surfaces of the inner wall of the fastening groove 8 are inclined surfaces, when the elastic plastic sheet 67 moves with the plug block 4, the curved surface of the fastening groove 8 passes over the elastic plastic sheet 67, so that the elastic plastic sheet 67 also quickly leaves the inside of the fastening groove 8, and the overall operation is convenient and quick, and it is convenient for subsequent disassembly.

[0038] 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.
