Description

The bottom stop resistor of separable slide fastener

Technical field

The utility model relates to a kind of bottom stop resistor of separable slide fastener, is applicable to that the open-type slide fastener uses, and makes to reach the anticreep effect.

Background technology

The separable slide fastener of habit formula, shown in No. the 340314th, 294909, Taiwan patent announcement, its bottom resistor structural feature: a thermoplastic resin case, a side has the exterior wall of cracking and being positioned at the pin receiving hole, and the bottom end of this exterior wall has one and ends part; Other has the ridge of leading of a thermoplastic resin system, and one embed and to have thin part between the pin, embeds pin and can go in the lock receiving hole, and thin part then can enter along cracking, and its bottom is subjected to stopping of stops and reaches locking function.

Aforementioned stop resistor can not firmly mesh bilateral sprocket when being configured with and produces the phenomenon that do not get loose, and still need have other different design to promote effect.

Summary of the invention

The purpose of this utility model is to provide a kind of bottom stop resistor of novel separable slide fastener.

The utility model stop resistor structure, it comprises that retaining is formed with lower claw down, this time retaining is that the one ejection formation is in the chain belt bottom, extend laterally out a reinforcing chip and reinforcing block on film by a block seat, have a tenon before the block seat, have a pawl groove in the side of tenon, the inner side edge of block seat has a fluting again, fluting is intercommunication with the pawl groove, and the bottom land of fluting and pawl groove has block and only sealed.

Lower claw is shaped in another chain belt bottom, extends laterally out a calvus and rest shoe on film by a bird pawl; , the bottom intercalation of bird pawl is subjected to block backstop but going in the aforesaid pawl groove, again bird pawl top have a trip can with the groove fit of tenon upper end, outstanding hook part, trip upper end can be colluded in sprocket and fix, in addition calvus thickness fluting for little, so can be in going into to slot along with the interspersed of bird pawl.

Effect of the present utility model:

1. the pawl channel opening of block seat can enter for the bird pawl, and bottom block can stop that the bird pawl enters, so that the bird pawl rests in the pawl groove, stops bird pawl bottom to produce and breaks away from.

2. the hook part of the trip on bird pawl top can be colluded in the sprocket of opposite side chain belt, breaks away to stop bird pawl top to produce.

3. reinforcing chip and reinforcing block can be at the strengthening actions of block seat tool, and rest shoe and calvus then can be at the strengthening actions of bird pawl tool.

4. the fluting spacing of block seat is less than the thickness of bird pawl, promptly can't be pulled out by the side with the side direction pulling force after making the bird pawl go into the pawl groove.

The specific embodiment

Following according to described embodiment detailed description of drawing as back:

Fig. 1 is a three-dimensional exploded view of the present utility model, the resistor of stop shown in figure structure 10 comprises that retaining 20 is formed with lower claw 30 down, this time retaining 20 is that the one injection molding is in chain belt 41 bottoms, extend laterally out a thin type reinforcing chip 22 and reinforcing block 23 on film 42 by a block seat 21, has a tenon 24 before the block seat 21, tenon 24 top inner edges have a groove 29, and side has a pawl groove 25, the inner side edge of block seat 21 has a fluting 26 again, fluting 26 is intercommunications with pawl groove 25, and the bottom land of two

grooves

26,25 has block 27 and seal only.

Fig. 2 is 2～2 sectional drawings of Fig. 1, and the rear portion of block seat shown in Fig. 3 21 has block 27 only to be sealed, and makes that pawl groove 25 and fluting 26 are not the hole slots that runs through; In addition, tenon 24 is provided in a side of the side of pawl groove 25, so the madial wall of tenon 24 can be used as the guide slides of lower claw bird pawl 31.

As Fig. 3 is 3～3 sectional drawings of Fig. 1, and 26 the top of fluting shown in Fig. 3 has a stops 28, with the usefulness of the bird pawl 31 that stops lower claw 30 as side direction, so 26 the spacing of slotting is less than pawl groove 25.Secondly, earlier figures 1 also illustrates lower claw 30, and it is integrally formed in another chain belt 44 bottoms, extend laterally out a calvus 32 and rest shoe 33 on film 45 by a bird pawl 31, and the base of calvus 32 has a breach 35.The top inner edge of bird pawl 31 is protruding with a trip 34, this trip 34 cooperates with the groove symmetry of aforementioned tenon 24, bird pawl 31 bottoms are deflection one low-angle inwardly, makes bird pawl 31 be easy to import in the pawl groove 25 of pull head (not shown) rail groove and block seat 21 by this deflection bottom.

As shown in Figure 4, be the front view after the utility model combination, the pawl of bird shown in the figure 31 bottoms can be inserted in the pawl groove 25 of block seat 21 and stopped by block 27, but the bottom of calvus 32 because of jagged 35 so do not contact with block 27; Bird pawl 31 top trips 34 have outstanding hook part up again, this trip 34 can cooperate (as Fig. 6) with tenon 24 upper end grooves 29, and can embed in last sprocket 43 of other side chain band 41 with outstanding hook part, and sprocket 44 and sprocket 46 engagements, bird pawl 31 is under the state that all is blocked up and down and break away from Y in can't be by the pawl groove 25 of block seat 21, so can reach fixing anticreep effect.

As shown in Figure 5, it is 26 little that calvus 32 thickness are slotted, so can go into along with interting of bird pawl 31 in the fluting 26; But it is 26 big that the thickness of bird pawl 31 is slotted, so bird pawl 31 is subjected to stopping of stops 28 in pawl groove 25, and can prevent the drawing of side direction pulling force.

As shown in Figure 7, be the rearview after the utility model combination, bottom surface and calvus 32 bottom surfaces that can find bird pawl 31 among the figure are (also can be observed out by Fig. 5) that are horizontal stepless, but the thickness of bird pawl 31 is thick than calvus 32, and bird pawl 31 bottoms are subjected to stopping of pawl groove 25 side stops 28 and reach side direction anticreep effect.

Because enforcement of the present utility model can be obtained following result:

1. bird pawl lower end is subjected to stopping of block seat block, reaches the upper end and is subjected to trip to embed stopping of sprocket, and prevent that the bird pawl from producing Y and facing upward or downward disengaging.

2. the bird pawl is subjected to stopping of side stops in the pawl groove, and prevents that the bird pawl from producing X and breaking away from.

3. at block seat and bird pawl not under the disengaged position, bilateral sprocket can firmly be meshed and do not get loose.

Claims

1. the bottom stop resistor of a separable slide fastener, it comprises retaining and lower claw down, this time retaining is that the one ejection formation is in the chain belt bottom, following retaining extends laterally out reinforcing chip and reinforcing block on film by block seat, have tenon before the block seat, the side of tenon has the pawl groove, and tenon top inner edge has groove, the block seat inner side edge has fluting again, and fluting is intercommunication with the pawl groove; And lower claw is shaped in another chain belt bottom, and it extends laterally out a calvus and rest shoe on film by the bird pawl, and bird pawl top inner edge protrudes trip, and the groove on this trip and the block seat tenon cooperatively interacts; It is characterized in that:
