Abstract

The invention discloses an elastic piece slider, and relates to the field of self-locking sliders capable of automatically rebounding. The elastic piece slider comprises a slider base, a puller, a connecting shaft, an elastic piece and a spring, wherein the slider base is provided with a downwards-sunken semicircular concave surface and a downwards-sunken cambered concave surface; the elastic piece is arranged in the cambered concave surface; a circular groove is also formed in the cambered concave surface; the spring is arranged in the circular groove; a rotating part and a locking part are arranged at the top end of the puller, and are adjacent on left and right; the rotating part is provided with a cambered surface; the locking part is provided with a protruded corner higher than the cambered surface; the elastic piece is rectangular and flaky, and is arranged in the cambered concave surface of the slider base; when the puller is arranged flat, the rotating part is pressed against the elastic piece, and the elastic piece is in a slightly bent state to slightly press the spring. According to the elastic piece slider, the puller can automatically rebound to automatically lock a zipper after being pulled by approximately 90 degrees, so that the slider is prevented from sliding when not being used, and the elastic piece can be prevented from being separated from the slider even when being damaged.

Description

technical field [0001] The invention relates to the field of zippers, in particular to a slider that can automatically rebound and has a self-locking function. Background technique [0002] In the slider for zipper with automatic locking device, the hook structure is usually used to realize the function of automatic rebound of the card. Patent 103220932A discloses a slider for zipper with automatic braking device. The slide fastener slider of the stopper device includes: a main body formed with a fastener element guide passage through which the fastener elements can penetrate; It has a locking claw protruding from a locking window hole formed in the above-mentioned main body into the above-mentioned chain element guide passage; a force applying part that applies force to the above-mentioned locking member so that the above-mentioned locking claw is released from the above-mentioned locking window hole Protruding into the above-mentioned chain element guide passage, the slid...
