Description
Technical Field
The invention belongs to the technical field of zippers, and particularly relates to a cap and an anti-false-opening puller with the cap.
Background
In the technical field of zippers, a zipper head is used for restraining opening and closing of a zipper; the main body of the slider has two leading-in ports and a meshing outlet, an upper plate and a lower plate, the upper plate is provided with a pull nose and is connected with the lower plate into a whole through a support core. The sliders in the prior art are generally divided into a self-locking slider and a non-self-locking slider, wherein the self-locking slider can effectively prevent sliding under a non-manual operation condition through an arranged self-locking mechanism.
The self-locking type puller comprises a puller body, a pulling piece, an elastic element, a cap and a horse hook, wherein the elastic element is fixed between the cap and the puller body, the pulling piece is pulled to drive the horse hook to be acted on the horse hook when the puller is used, the horse hook is not lifted enough, the puller body is pulled through the pulling piece, and the puller body slides on the zipper to realize the opening and closing of the zipper. The elastic element generally is the spring leaf, the spring leaf installation back, the spring leaf middle part is downwards protruding, whole spring leaf is similar to the inverted arch shape, when the camber of spring leaf is great, need exert great power to the pulling-on piece and just can lift up the horse hook, when the camber of spring leaf is less, then the elasticity of spring leaf is less, can't become effectual roof pressure to the horse hook, the horse hook is difficult to carry out effectual braking to the zip fastener, the pull head gliding probably appears, and this kind of spring leaf extends when the atress, then cause the spring leaf can't reset and lose due elasticity when the atress is too big, finally influence the auto-lock function of pull head. When the spring leaf is installed in the cap, the cap is riveted from two sides of the cap, so that the local inward deformation of the cap is limited, when the riveting is excessive, the cap is excessively concave, the difficulty is increased when the cap is subsequently assembled to the pull head body, and even the assembly is difficult, therefore, the spring leaf is not easy to control when being assembled, the assembly difficulty is larger, and the spring leaf is mainly fixed through the cap, so that the difficulty of the cap is increased when being assembled.
