A slider is slidably installed on the pair of chain teeth, and the meshing parts of the chain teeth mesh with each other by the passage of the slider. A stopper is provided at the end of the chain tooth row of the belt parts to prevent the slider from sliding. The stopper is also made of synthetic resin and installed on the belt parts by injection molding.

[0004] In the above scheme, the upper stops are arranged on both sides of the zipper, resulting in the following disadvantages: when the zipper puller is lifted to the position of the upper stopper, the zipper puller cannot move forward, and the zipper puller that loses power may gradually slide down, reducing the effect of the zipper when in use. Utility Model Content

[0005] The utility model aims to provide an invisible zipper anti-slip top stop to solve the problem that a zipper pull head which loses power may gradually slide down, thereby reducing the effect of the zipper when in use.

[0007] Preferably, a fixing groove is provided on one side of the anti-slip upper stop body, and the fixing groove is slidably inserted into the inner lining of the invisible zipper.

[0008] Preferably, installation openings are respectively opened on both sides of the interior of the fixing groove, a melting strip is arranged inside the installation opening, a plurality of connecting columns are respectively fixed on both sides of the melting strip, and the other end of the connecting column is fixed to one side of the interior of the installation opening.

[0009] Preferably, a pressing plate is slidably provided inside the connecting groove, and two spring sheets are fixed on the top surface of the pressing plate.

[0010] Preferably, a sliding hole is provided on the top surface of the spring sheet, a sliding rod is slidably inserted inside the sliding hole, the bottom end of the sliding rod is fixed to the inner bottom surface of the spring sheet, a spring is surrounded by the surface of the sliding rod, one end of the spring is fixed to the inner bottom surface of the spring sheet, and the other end of the spring is fixed to the inner top surface of the spring sheet, and two accommodating holes are provided on the top surface of the anti-slip upper stop body, and the accommodating holes are slidably inserted into the sliding rod.

[0011] Preferably, the four corners of the anti-slip upper stop body are respectively provided with protective obtuse angles.

[0012] Compared with the prior art, the invisible zipper anti-slip top stop adopting the above technical solution has the following advantages:

[0013] Beneficial effects:

[0014] 1. When the user pulls up the slider of the invisible zipper, the slider will move to the same height as the anti-dropping upper stop body, and then the user will guide the edge of the slider into the inside of the slide-in groove, and then the edge of the slider will slide through the slide-in groove into the inside of the connecting groove, and move horizontally inside the connecting groove, enter the inside of the limiting groove, and slide downward inside the limiting groove, so that the slider can be locked in the current position to prevent the slider from falling off;

[0015] Second, when the anti-slip upper stop body is installed on the invisible zipper lining, the invisible zipper lining will be inserted into the fixing groove, and then the user will heat-press the two melting strips so that the two melting strips are close to each other and melt and fuse with the invisible zipper lining, so that the anti-slip upper stop body can be fixed. If the user's chin contacts the anti-slip upper stop body, the protective obtuse angle can protect the skin of the user's chin, thereby increasing the firmness between the anti-slip upper stop body and the invisible zipper lining;

[0016] 3. When the slider of the invisible zipper is restricted inside the limiting groove, the pressing plate slides upward because the slider is pushed and compresses the spring sheet while sliding. When the slider is positioned inside the connecting groove, the compressed spring sheet pushes the pressing plate to exert a downward force on the slider, thereby pressing the slider to be restricted inside the connecting groove and preventing the slider from slipping out of the connecting groove.
