Abstract

A copper zipper slider having protrusions, comprising a slider body (1), an elastic piece (2), and a pull tab (3). The slider body (1) comprises a top board (11), a bottom board (12), and a guide post (13) connecting the front end of the top board (11) and the front end of the bottom board (12). The pull tab (3) consists of a pulling portion (31) and a rotating portion (32). The rear part of the top board (11) is provided with a protrusion block (4). The middle part of the top board (11) is provided with a protrusion layer (5) protruding upward from the upper surface of the top board (11). The front side (21) of the elastic piece (2) is riveted to the guide post (13). The rear side (22) of the elastic piece (2) is provided with a first through hole (23), and is movably fastened against the outer side of the protrusion block (4) by means of the first through hole (23). The rotating portion (32) is located between the elastic piece (2) and the top board (11) in the vertical direction, and between the protrusion block (4) and the protrusion layer (5) in the horizontal direction. When the pulling portion (31) is pulled forward, the rotating portion (32) can abut against an outer side wall of the protrusion layer (5). By providing the protrusion layer (5), when the pull tab (3) is rotated, the rotating portion (32) can directly abut against the outer side wall of the protrusion layer (5), without applying pressure to the elastic piece (2). Thus, the elastic piece (2) can be effectively prevented from plastic deformation, and the service life of a zipper can be prolonged.

Description

Copper slider with protrusion

Technical field

The present invention relates to the field of zippers, and more particularly to a copper slider having a projection.

Background technique

Most of the existing copper sliders are composed of a slider body, a spring piece and a pull tab. The quality of the spring piece is high. As long as the spring piece is deformed, the entire copper slider is declared damaged. Therefore, the copper slider design is heavy. The important thing is to avoid the deformation of the shrapnel in use, and the existing copper slider is difficult to solve this problem effectively.

The invention relates to a zipper slider with a locking device (authorization bulletin number CN1165252C), which comprises: a protruding member disposed on the rear portion of the upper plate of the slider body and a set of pawl holes; a groove in the front surface of the guide post and having an engaged portion: a leaf spring having an inverted U shape and including a locking pawl at one end thereof and a sagging portion having an engaging portion at the other end thereof a engaging tongue member disposed in a center substrate such that it extends from the center substrate to have a curved shape; a portion disposed adjacent to the locking pawl and the rear protruding member a freely and movably engaged hooking hole; the engaging portion of the hanging member engaged with the engaged portion: and a pivoting shaft having a pulling cam portion disposed at the rear projection Between the protruding member and the engaging tongue member; the zipper slider is characterized in that a contact portion is formed on the front portion of the upper plate by a protruding member or a through hole; the engaging tongue member is mounted on the upper portion The plate so that it can always slide with the contact contact. In the patent, when the pull tab is pulled, the pull tab directly acts on the leaf spring, and is used for a long time and is easily damaged.

The invention relates to a slider for a zipper with a locking device (authorization bulletin number CN1268249C), which discloses that a plate spring is mounted on the body, the locking claw of which is bent from one end thereof and the spring portion from the other end and the locking claw Bending in the same direction. The spring portion of the plate spring is fixed to the front end of the guide post of the body such that the bent portion is exposed to the guide post. The pull tab is mounted between the body and the plate spring. A cam is disposed on the bottom surface of the shaft of the pull tab. When the pull tab is placed on the front side of the body, a gap is formed between the side of the through hole and the bent portion to prevent plastic deformation of the leaf spring. However, this patent can only solve the plastic deformation of the plate spring when the pull tab is placed on the front side of the body, and the pulling force still needs to exert a force on the plate spring during use, which still accelerates the wear speed of the plate spring. .

The invention discloses a zipper slider with an automatic stopper (authorization bulletin number CN1301675C), which discloses a slinging member capable of accommodating a reed in a front surface of a guide post of the slider. In the main body of the slider, one upper piece and one lower piece are connected to each other by a guide post, and the front surface of the guide post is provided with a groove portion continuously open in a vertical direction. The sagging member formed by bending one end of the spring of the automatic stopper mechanism on the top surface of the upper sheet is engaged and located in the groove portion, and the bottom end of the groove portion is provided with a projecting portion which protrudes forward. The protruding portion is located below the hanging member to protect the front end of the hanging member, and the shape of the protruding portion prevents a sharp object from being inserted between the hanging member and the protruding portion, thereby protecting the slider from accidental damage. However, this patent can only prevent the sharp object from being inserted between the hanging member and the protruding portion to protect the slider, and can not effectively solve the problem that the elastic piece is deformed in long-term use.
