Description

Can increase the self-locking slider of zipper fastener of drawing strength

The utility model relates to a kind of self-locking slider of zipper fastener that increases drawing strength, refers to that especially a kind of be suitable for put nylon zipper, can effectively increase the self-locking slider of zipper fastener structure of drawing strength.

At present, existing self-locking slider of zipper fastener structure, it includes a slider of zipper fastener body, one draw ring and a shell fragment constitute, this draw ring is to be articulated on the slider of zipper fastener body, and can utilize draw ring to spur this slider of zipper fastener in order to control the closed of slide fastener or to separate, this shell fragment is to be positioned on this slider of zipper fastener body, this shell fragment is to have a blocking part, this blocking part can run through this slider of zipper fastener bodies top and be inserted into this slider of zipper fastener body interior, so that clip is on slide fastener, make this draw ring end when pulled slider of zipper fastener can be a clip stationary state, because the intensity of this shell fragment is limited, even slider of zipper fastener under the clip stationary state, still might cause its drawing strength relatively poor because of the external force effect produces unexpected moving.

The purpose of this utility model provides a kind of self-locking slider of zipper fastener that increases drawing strength, and it has preferable drawing strength.

For achieving the above object, the utility model is taked following design:

A kind of self-locking slider of zipper fastener that increases drawing strength is characterized in that: be provided with:

One slider of zipper fastener body, its inside is formed with two chutes, and this slider of zipper fastener bodies top is provided with a perforation;

One draw ring, the one end has an articulated section, and it is articulated in this slider of zipper fastener bodies top;

One shell fragment, it has a fixed part, this fixed part one end is connected with one first bend, this first bend, one end is connected with one second bend, this second bend, one end is connected with a blocking part, this second bend is provided with a groove that extends along its length, this shell fragment is to be positioned this slider of zipper fastener bodies top with fixed part, and second crooked position of this shell fragment is in top, the articulated section of this draw ring, and makes the perforation that the blocking part of this shell fragment runs through this slider of zipper fastener body be inserted between two chutes.

Because it is poor that a ditch is set on second bend of this slider of zipper fastener shell fragment, this groove can make second bend form concaveconvex shape, so have the effect of reinforcement, the intensity of second bend of shell fragment is significantly increased, better intensity can be provided under the principle that shell fragment thickness does not increase, make slider of zipper fastener under the clip stationary state, can effectively prevent unexpected moving, to have preferable drawing strength.

The utility model is described in further detail below in conjunction with accompanying drawing
