Description

The invisible zipper head improvement

The utility model system is relevant for haberdashery, particularly about slide fastener.

General CONCEAL ZIPPER sprocket often colludes by invisible zipper head and the pull handle gone up thereof and closes pulling-on piece and draw and open, and makes it to sew up or separately.But when in dress if the careless application of force arranged or move when excessive, the easy slippage of invisible zipper head causes and wears nation or inconvenience is arranged.Moreover, owing to the piece A1 that presses that practises that formula invisible zipper head A (as Fig. 1) central authorities are pivoted utilizes in it spring of installing to form to have elastic force, spur up and down via pulling-on piece A2 and press piece A1, make the closed or separation of zipper sprocket.Thus, though this invisible zipper head A can be when static, prevent landing or get loose that its invisible zipper head A part complexity is assembled inconvenience again, by contrast, labor intensive, man-hour and cost.

Be early dark in being denounced with the dealer with the mentioned disappearance of, traditional type invisible zipper head.Therefore, improved at its disappearance, with intention and the structure of earnestly hoping the best, and in order to do the product person who reaches practicality, progresses greatly.Based on aforementioned creation theory, aforementioned member complexity, the assembling of commonly using invisible zipper head of the artificial effectively improvement of the utility model design expends time in, the problem of cost, it is the active research innovation, gather many outer experience gains in depth of comprehension of being engaged in this product designing for manufacturing, break through the restriction of conventional art level, go through continuous effort and improve development, have breakthrough finally and initiate out the utility model.

Edge this, the utility model ties up to provides the improvement of a kind of invisible zipper head, it overcomes the above-mentioned disappearance of commonly using invisible zipper head, its purpose is to make the DE of its reed better, is easy to pulling-on piece pulling back reinstatement.Simple in structure, easy to assembly, can prevent that simultaneously latent table slider of zipper fastener from producing slippage or get loose in inactive state (pulling up and down).

The purpose of this utility model is achieved in that a kind of invisible zipper head improvement, include invisible zipper head body, reed, pulling-on piece and pull handle, it is characterized in that: the projection leading edge that distal process is established before this invisible zipper head body below base plate central authorities conduit upwards extends a below has draw-in groove, top that the block of bead is arranged, and these bead central authorities dig and are provided with perforation; This reed is to be provided with not-go-end and to fasten to hold and bend the strip shape body that takes the shape of the letter U; The not-go-end of this reed snaps in the draw-in groove of this invisible zipper head body block below, and it fastens end and then penetrates in the perforation of this block top bead, fastens to form a pull handle between bottom edge and bead and collude the elastic space that closes pulling-on piece pulling reed.

Above-mentioned invisible zipper head improvement is characterized in that: this reed upper punch is provided with the not disconnected piece that presses that is taper of disjunctor; This invisible zipper head body projection rear end is provided with for this and presses the breach that piece passes.

The utlity model has following advantage:

1. the reed that takes the shape of the letter U of bending is after installing on the invisible zipper head body, form a pull handle and collude the elastic space that closes pulling-on piece pulling reed, so make its DE better, help the recovery after pulling-on piece spurs, and make sprocket closed or separate fast, avoid because of the application of force or move invisible zipper head when excessive slide fastener that landing causes wear nation and embarrassment.

2. simple in structure, be convenient to assembling, saving of work and time reduces cost.

Below in conjunction with drawings and Examples the utility model is described below:

The invisible zipper head stereogram is commonly used by Fig. 1 system.

Fig. 2 is the three-dimensional exploded view of utility model.

Fig. 3 is that the utility model pulling-on piece upwards spurs the reed schematic diagram.

Fig. 4 is that the utility model pulling-on piece pulls down the movable contact spring schematic diagram.

At first, see also shown in Figure 2ly, the utility model includes invisible zipper head body 1, a shell fragment 2, a pulling-on piece 3 and a pull handle 4.Distal process is established projection 12 before the central conduit 11 of this invisible zipper head body 1 below base plate 10, and projection 12 leading edges upwards extend a below has draw-in groove 130 tops that the block 13 of bead 131 is arranged.Bead 131 central authorities dig and are provided with perforation 132, establish disconnected and be reed 2 that taper presses piece 20 for its upper punch to fasten end 21 and wear.These reed 2 cordings have not-go-end 22 and fasten the elongate body of end 21, and are bent into the U type by not-go-end 22 to the upper left side.Fastening of this reed 2 holds 21, penetrates in the perforation 132 of invisible zipper head body 1 block 13 top beads 131, at this moment, fastens 131 formation of end 21 root edges and bead, one pull handle 4 and colludes the elastic space 23 (as Fig. 3) that closes pulling-on piece 3 pulling reeds 2.The not-go-end 22 of this reed 2 snaps in the draw-in groove 130 of invisible zipper head body 1 projection 12 leading edge blocks 13 belows.These reed 2 upper punches be provided with disjunctor disconnected and be taper press piece 20.This presses piece 20 and is arranged in the breach 120 of projection 12 rear ends; By this with the block sprocket, prevent 1 landing of invisible zipper head body or get loose.Colluding the pull handle 4 that closes pulling-on piece 3 is nested with at the not-go-end 22 of reed 2 and fastens between the end 21.When pulling-on piece 3 upwards spurs reed 2 (as Fig. 3), press piece 20 and slide along the sprocket arc end, be about to make the sprocket closure.When pulling-on piece 3 pulls down movable contact spring 2 (as Fig. 4), pressing piece 20 upwards moves along with the elastic force of pulling-on piece 3 pulling reeds 2, making simultaneously to fasten holds 21 root edges to resist in bead 131, make sprocket separated fast, can avoid invisible zipper head body 1 because of the application of force or landing when excessive of moving, cause and wear nation or inconvenience is arranged, it is good to increase practicality, spurs invisible zipper head up and down to reach.So when static, then make invisible zipper head be the block shape, place and this main creation that is the utility model will be anticipated.

Claims (2)

1, a kind of invisible zipper head improvement includes invisible zipper head body, reed, pulling-on piece and pull handle; It is characterized in that: the projection leading edge that distal process is established before this invisible zipper head body below base plate central authorities conduit upwards extends a below has draw-in groove, top that the block of bead is arranged, these bead central authorities dig and are provided with perforation, this reed is to be provided with not-go-end and to fasten to hold and bend the strip shape body that is the U type, the not-go-end of this reed snaps in the draw-in groove of this invisible zipper head body block below, it fastens end and then penetrates in the perforation of this block top bead, fastens to form a pull handle between bottom edge and bead and collude the elastic space that closes pulling-on piece pulling reed.

2, invisible zipper head improvement according to claim 1 is characterized in that: this reed upper punch is provided with the not disconnected piece that presses that is taper of disjunctor, and this invisible zipper head body projection rear end is provided with for this and presses the breach that piece passes.
