Description

The Skidproof structure of slide fastener

The utility model relates to a kind of slide fastener, is a kind of Skidproof structure of slide fastener specifically.

The Skidproof structure of general traditional slide fastener, its device construction is a slider of zipper fastener, this slider of zipper fastener is provided with a fluting, be provided with a perforate that runs through slider of zipper fastener in this fluting, then respectively be provided with a breach in the fluting both sides, be equipped with a draw ring in this breach, this draw ring is arranged with a lamellar body that is fork-shaped on one end in fluting, the end that this lamellar body protrudes passes perforate and protruding being exposed in the slide fastener, the other end is resisted against on the inwall of fluting, moreover, be provided with the lid that is installed with on the fluting two ends on the lamellar body, this lid inwall is provided with a reed, and this reed just can be connected on the lamellar body.This kind device during fabrication, not only part increases manufacturing cost more, and need expend a large amount of artificial and process assembling man-hour, trouble very on making.In addition; in use; be to be arranged at versatilely in the fluting because of lamellar body especially; when the user spurs draw ring and strap body and upwards moves apart; not only lamellar body regular meeting departs from original position because of tearing of draw ring, more can be after the user unclasp draw ring, when reed presses lamellar body downwards by elastic reaction; lamellar body protrudes and can't pass slider of zipper fastener and protruding being exposed in the slider of zipper fastener, and is more undesirable in the use.

For improving above-mentioned defective, the inventor develops the utility model through permanent effort research and experiment constantly.

The purpose of this utility model is to provide a kind of Skidproof structure of slide fastener, and slider of zipper fastener can be fixed on the optional position of slide fastener, and makes slide fastener when upwards pullling, and can guarantee the condensation of draw ring energy in slotted eye, and then slider of zipper fastener can be slided on tooth bar smoothly; Should make in addition it easy to assembly and use simple.

The purpose of this utility model foot is realized like this; A kind of Skidproof structure of slide fastener, it includes a rank and attaches together and put and a draw ring, this rank attaches together to put and is provided with the opening that along continuous straight runs is offered, one end of this opening is provided with the retaining head that connects the framework both sides, it is characterized in that described rank attaches together to put on the end away from retaining head is provided with slotted eye, this slotted eye is connected with opening, and this rank is closed element and is provided with the pivot seat at contiguous slotted eye place, is provided with recessed breach in this pivot seat; Draw ring is hubbed on this pivot seat, and this draw ring is provided with the withstanding part that protrudes out along the draw ring horizontal direction in the breach of pivot seat; One fastens element, this fastens element one end and is fixed on rank and closes element and have on the end limit of retaining head, the other end is then through breach and be pressed against on the draw ring on the breach, and sleeve is in slotted eye, this fastens the element sleeve and is provided with the stopper section of protrusion in groove one end, in the opening that this stopper section just can protrudingly be exposed to slotted eye communicates.

The purpose of this utility model also can be by descending measure to realize that the described element that fastens can be rubber-like metal lamellar body.

Operation principle of the present utility model and effect are, when draw ring is upwards pullled, make and keep the withstanding part of equality in draw ring also contact is fastening on the element thereupon moving, move up fastening the end of element sleeve in slotted eye, and then make this end protrude out stopper section in opening originally to contract thereupon and retract in the slotted eye, allow rank close element and successfully slide on the tooth bar.Otherwise, closing element as rank arrives when giving fixed position, draw ring hangs naturally and closes on the element in rank, so that the withstanding part on the draw ring can move thereupon, no longer contact is got back in the opening and the stopper section that fastens element is stretched along slotted eye fastening element, and then is pressed on the tooth bar, so that closing element, rank can be fixed on the position at place unlikely downward landing.

In sum, prior art is compared in the utility model, and is simple in structure, and assembling is easy, and reliable in action.

The explanation of accompanying drawing drawing:

Fig. 1 three-dimensional exploded view of the present utility model;

The action schematic diagram that Fig. 2 is of the present utility model when implementing;

The action schematic diagram that Fig. 3 is of the present utility model when implementing;

It is as follows to describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof;

Please show that the utility model mainly comprises the slider of zipper fastener 10 of a control slide fastener folding referring to Fig. 1, this slider of zipper fastener 10 includes:

One rank is closed element 20, it is a framework that this rank is closed element 20, be provided with an opening 21 in this framework, these opening 21 both sides respectively are provided with the flange 22 that bends inwards, then be provided with a retaining 23 that connects the framework both sides at opening 21 1 ends, and the surface that rank is closed element 20 is provided with pivot seat 24, and this pivot seat 24 is provided with caulking groove 241, and this pivot seat 24 is provided with recessed breach 242; In addition the rank surface of closing element 20 is provided with grip slipper 25 on the other end of contiguous retaining 23, then is provided with a slotted eye 26 on the other end away from retaining 23, and this slotted eye 26 also is connected in opening 21, and this slotted eye 26 is arranged on contiguous pivot seat 24 places.

One draw ring 30, it is hubbed on the caulking groove 241 of pivot seat 24, and draw ring 30 is provided with the withstanding part 31 that protrudes out along draw ring 30 horizontal directions in the breach 242 of pivot seat 24.

One fastens element 40, it is one to close element 20 and rubber-like metal lamellar body across rank, fastening element 40 1 ends is fixed on the grip slipper 25, the other end is then through breach 242 and be pressed against draw ring 30 on the breach 242, and then sleeve is in slotted eye 26, this fastens element 40 sleeves in the stopper section 41 that an end of slotted eye 26 is provided with, and this stopper section 41 just can protrudingly be exposed in the opening 21 that is connected with slotted eye 26.

See also Fig. 1 to shown in Figure 3, operation principle of the present utility model is, when rank is closed element 20 and is interposed on the tooth bar, draw ring 30 upwards can be pullled, making draw ring 30 not close a end that element 20 articulates with rank closes element 20 away from rank and upwards lifts, and make draw ring 30 keep the withstanding part 31 of equality also to move thereupon, contact is fastening on the element 40, fasten the end of element 40 sleeves in slotted eye 26 and move up and make, and then make this end protrude out stopper section 41 in opening 21 originally to contract thereupon and retract in the slotted eye 26, allow rank close element 20 and successfully slide on the tooth bar, as shown in Figure 3.Otherwise, closing element 20 as rank arrives when giving fixed position, earlier with openhanded from draw ring 30, draw ring 30 is hung naturally close on the element 20 in rank, so that the withstanding part 31 on the draw ring 30 can move thereupon, no longer contact is fastening element 40, and can being stretched along slotted eye 26, the stopper section 41 that fastens element 40 1 ends gets back in the opening 21, and then be pressed on the tooth bar, so that closing element 20, rank can be fixed on the position at place unlikely downward landing.
