Description

A kind of self-locking zipper slider
Technical field
The utility model relates to a kind of slider of zipper fastener for slide fastener, is specifically related to a kind of self-locking zipper slider.
Background technology
Slide fastener is installed to the opening portion of bag, bag and clothes etc., and is made chain tooth be separated by the slide of slider of zipper fastener or engagement, makes this opening portion open or close.In order to prevent slider of zipper fastener from surprisingly opening, some slider of zipper fasteners are with auto-lock function.
Conventional self-locking zipper slider as shown in Figure 1, it comprises body 1 ', spring leaf 2 ' and draw ring 3 ', the tail end 21 ' of described spring leaf 2 ' is fixed on body 1 ', the front end 22 ' of spring leaf 2 ' is through draw ring 3 ', and bend downwards, the front end 22 ' of spring leaf 2 ' has lock pawl 23 ', draw ring 3 ' is limited between body 1 ' and spring leaf 2 ', the width of the frame 31 ' of draw ring 3 ' is greater than thickness, body 1 ' is provided with a pawl hole 15 ', lock pawl 23 ' extend into the chain alveolus 14 ' of body 1 ' from pawl hole 15 ', spring leaf 2 ' has a through hole 25 ' above lock pawl 23 ', body 1 ' is provided with the lug 16 ' of a upper-end bent, this lug 16 ' fastens mutually with through hole 25 ', the middle part of described spring leaf 2 ' has a pair shoulder 26 ', body 1 ' is provided with the spacing barb 18 ' that anti-ending shoulder 26 ' is excessively elevated, the front end 22 ' of the shoulder 26 ' and spring leaf 2 ' that draw ring 3 ' are limited in spring leaf 2 ' is downwards between bending place, prevent draw ring 3 ' from moving to the tail end 21 ' of spring leaf 2 ' and making spring leaf 2 ' produce plastic deformation.
Draw ring is lain on body, and lock pawl extend into the chain alveolus of body from pawl hole, and embeds in the chain teeth space gap of slide fastener, stops slider of zipper fastener to slide; Draw ring lifts, and is vertically placed on body, because the width of the frame of draw ring is greater than thickness, is lifted by spring leaf, and lock pawl departs from the chain teeth space gap of slide fastener, and slider of zipper fastener now can be pulled to be closed by slide fastener; Stop drag slider of zipper fastener, draw ring is set level again, and under the effect of spring leaf, lock pawl again in embedded chain teeth space gap, thus plays self-locking action.
The self-locking zipper slider of this structure, because barb is higher than the surface of spring leaf, barb is easily subject to external force and directly clashes into generation distortion or fracture, such as: when ironing clothes, when flatiron is through slider of zipper fastener, often barb collision deformation, thus spring leaf is compressed, draw ring cannot be relied on spring leaf jack-up, make slider of zipper fastener ineffective; Barb likely bumps against on neighbouring thing impaired in addition.Simultaneously because the shoulder bending part of spring leaf is the position that stress is concentrated, when external force applies repeatedly, spring leaf easily ruptures.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure, long service life, not easily loses efficacy when being subject to the shock of external force, and through the self-locking zipper slider of repeatedly Reusability spring leaf not easy fracture.
The technical solution realizing the utility model object is: a kind of self-locking zipper slider, comprise body, spring leaf and draw ring, the tail end of described spring leaf is fixed on body, the front end of spring leaf is through draw ring, and bend downwards, the front end of spring leaf has lock pawl, draw ring is limited between body and spring leaf, the width of the frame of draw ring is greater than thickness, body is provided with a pawl hole, lock pawl extend into the chain alveolus of body from pawl hole, it is characterized in that, the middle part of spring leaf is provided with a reclinate stop tongue, body is provided with the opening that an accommodation stops tongue, draw ring is limited in and stops between tongue and the downward bending place, front end of spring leaf.
Further, described body is provided with the block preventing draw ring to the movement of spring leaf tail end, and block is positioned at the below of spring leaf.
Described body is provided with the boss at support spring sheet rear portion.
A kind of self-locking zipper slider of the utility model has following beneficial effect: spring leaf is provided with stop tongue, draw ring is limited in and stops between tongue and the downward bending place, front end of spring leaf, prevent draw ring from moving to the tail end of spring leaf and causing spring leaf to produce plastic deformation; The topside perspective of spring leaf is straight, and there is not the position that stress is concentrated, spring leaf is Reusability repeatedly, also not easy fracture; Slider of zipper fastener upper flat, when the shock being subject to external force also not easily lost efficacy; Rational in infrastructure, long service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated;
Fig. 1 is the structural representation of the slider of zipper fastener of known conventional self-locking.
Fig. 2 is structural representation of the present utility model,
Fig. 3 is that structure of the present utility model splits schematic diagram, the tail end of the non-stationary spring of body in figure;
Detailed description of the invention
As Fig. 2, shown in Fig. 3, a kind of self-locking zipper slider, comprise body 1, spring leaf 2 and draw ring 3, described body 1 is made up of upper panel 11 and lower panel 12, upper flange 11 is connected with lower wing plate 12 by guide pillar 13, chain alveolus 14 is formed between upper flange 11 and lower wing plate 12, guide pillar 13 has holding tank 131, the tail end 21 of spring leaf 2 is placed in the holding tank 131 of guide pillar 13, by the tail end 21 of the both sides crimping of holding tank 131 by spring leaf 2 is fixedly clamped, the front end 22 of spring leaf 2 is through draw ring 3, and bend downwards, draw ring 3 is limited between body 1 and spring leaf 2, the width of the frame 31 of draw ring 3 is greater than thickness, the front end 22 of spring leaf 2 has lock pawl 23, body 1 is provided with a pawl hole 15, lock pawl 23 extend into the chain alveolus 14 of body 1 from pawl hole 15, spring leaf 2 has a through hole 25 above lock pawl 23, body 1 is provided with the lug 16 of a upper-end bent, this lug 16 fastens mutually with through hole 25, the middle part of spring leaf 2 is provided with a reclinate stop tongue 24, body 1 is provided with the opening 17 that an accommodation stops tongue 24, draw ring 3 is limited between downward bending place, the front end 22 stopping tongue 24 and spring leaf 2, described body 1 is provided with the block 18 preventing draw ring 3 to the movement of spring leaf 2 tail end, and block is positioned at the below of spring leaf, this block with stop that tongue cooperatively interacts, prevent crossing of draw ring 3 from stopping tongue 24, avoid obtaining spring leaf 1 plastic deformation and losing efficacy.
Described body is provided with the boss 19 at support spring sheet rear portion, described boss 19 to be placed between the opening 17 of body and guide pillar 11 and to be positioned at the below of spring leaf 2, be combined with above-mentioned block 18, support spring sheet 2, avoids spring leaf 2 be subject to downward pressure and produce plastic deformation simultaneously.
