Abstract

Add groove flexible plastics shoe garrison backstay by force props before including, corrugated extension tube and heel, prop before, corrugated extension tube and heel be whole linking to each other, the corrugated extension tube top sets up the recess, makes every section corrugated crest of matching, the high B<of two crests, the high L of crest, B=0.1's - 0.3 L. The characteristic that had both kept original corrugated extension tube, the flexible ability at ripple top has been increased again, there has been the recess, shoe garrison backstay compression back, corrugated extension tube's both sides can reach sharp state, further strengthen corrugated extension tube's compression and resilience, utilize the width of recess, can control flexible distance, utilize the degree of depth of recess, can control the thickness of the wall, thereby make the product reach the flexible ability of the best, and can keep corrugated extension tube's elasticity, increase crooked ability, prolonged service life, the effort of ripplet is softer, it is easy to put into shoes, put into the shoes back, can not resist stubbornly anterior production of shoes, avoid the anterior of shoes to warp.

Description

Add groove strong telescopic plastic fillers

Technical field

This utility model relates to fillers, particularly relates to one and adds groove strong telescopic plastic fillers.

Background technology

In order to prevent vamp to be squeezed or natural depressed deformation, in footwear, generally put chock, such as with spitball or sponge etc., Such chock does not has self-regulation ability, and particularly toe cap etc. is difficult to relate to, and support effect is the best.For this problem, this A person of good sense once designed a kind of adjustable aerated shoe stretcher, its Patent No. ZL200420082093.9, solve original technically The non-retractable problem of fillers size, but easily leak after needing configuration tool, and inflation during the inflation of this fillers, support Ability reduces, and uses trouble.The footwear that the present inventor designed again a kind of simple in construction later, length can be stretched according to footwear size Support, its structure supports and heel before including, connects plastic ripple telescoping tube, but existing plastic ripple stretches between front support and heel Pipe often joint ripple size is consistent, and flexible ability puts into taking-up laborious.The present inventor develops again a kind of band spring still later Fillers, its Patent No. ZL201020114635.1, spring is set in telescoping tube, although this fillers enabling capabilities is good, but by Ever-changing in the shape of footwear, and fillers can not be made to perfect in every way, so the shape of fillers and footwear, the most inconsistent, Due to the long duration of action by spring force, being easy for the shape making footwear and deform along with fillers, and arrange spring, structure is multiple Miscellaneous, assembling trouble, cost is high.

Summary of the invention

The purpose of this utility model is the shortcoming in order to overcome prior art to exist, it is provided that a kind of contractility is strong, and compression is light, Good springiness, puts into footwear easy, footwear inner support soft add groove strong telescopic plastic fillers.

This utility model adds the technical scheme of groove strong telescopic plastic fillers, including front support, bellows and heel, its Front support, bellows and the heel being characterised by described is one to be integrally attached to, and arranges groove at the top of bellows, makes Often joint ripple forms dual waves, the L of the height L, B=0.1 0.4 of the height B < crest of dual waves.

The utility model discloses one and add groove strong telescopic plastic fillers, it is mainly technically characterized ny before making with plastics Support, bellows and heel are an all-in-one-piece fillers, arrange groove at the top of bellows, and groove is equivalent to small echo Stricture of vagina, makes often to save ripple and forms dual waves, be equivalent to have between big ripple ripplet, the height L, B=of the height B < crest of dual waves 0.1 0.4L, had both maintained the characteristic of original bellows, added again the flexible ability at ripple top, at big ripple The groove of ripplet has been arranged at top, and after fillers compression, the both sides of bellows can reach linear state, strengthens ripple further The compression of telescoping tube and resilience, utilize the width of groove, can control distance of stretch out and draw back, utilizes the degree of depth of groove, can control The thickness of wall processed, so that product reaches optimal flexible ability, and can keep the elasticity of bellows, increase bending energy Power, increases the service life, and the force ratio of ripplet is milder, puts into footwear easy, after putting into footwear, and will not be to shoes Anterior generation is resisted stubbornly, it is to avoid the anterior deformation of footwear.

Of the present utility model adding groove strong telescopic plastic fillers, the bottom of described groove is U-shaped arc transition.Circular arc mistake Cross, improve bonding strength, when fillers puts into footwear, make bellows when bend tension, it is to avoid tear.Described dual waves Top make circular arc, it is ensured that the thickness that dual waves top is certain, increase fastness, service life is long.The height of described dual waves Degree B is 1 6mm, and width C is 1 6mm.Described groove is triangular groove, the groove of triangle, compresses, stretches easily.

Detailed description of the invention

This utility model relates to one and adds groove strong telescopic plastic fillers, as shown in Fig. 1 Fig. 7, stretches including front support 1, ripple The draw 2 and heel 3, it is characterised in that described front support 1, bellows 2 and heel 3 is one to be integrally attached to, at bellows The top of pipe 2 arranges groove 4, makes often to save ripple and forms dual waves, the height L, B=0.1 of the height B < crest of dual waves 0.4L.It is mainly technically characterized ny support 1 before making, bellows 2 and heel 3 with plastics is an all-in-one-piece fillers, at ripple The top of stricture of vagina telescoping tube 2 arranges groove 4, and groove 4 is equivalent to ripplet, makes often to save ripple and forms dual waves, is equivalent to big ripple Between have ripplet, height L, the B=0.1 0.4L of the height B < crest of dual waves, both maintained original bellows 2 Characteristic, adds again the flexible ability at ripple top, has had the groove 4 of ripplet at the top of big ripple, after fillers compression, and ripple The both sides of stricture of vagina telescoping tube 2 can reach linear state, strengthens compression and the resilience of bellows 2 further, utilizes groove 4 Width, distance of stretch out and draw back can be controlled, utilize the degree of depth of groove, the thickness of wall can be controlled, so that product reaches optimal Flexible ability, and the elasticity of bellows can be kept, increase crooking ability, increase the service life, the force ratio of ripplet Milder, put into footwear easy, after putting into footwear, the anterior generation of shoes will not be resisted stubbornly, it is to avoid the anterior deformation of footwear.Institute The bottom stating groove is U-shaped arc transition.Arc transition, improves bonding strength, when fillers puts into footwear, makes bellows Pipe is when bend tension, it is to avoid tear.Circular arc 5 is made at the top of described dual waves, it is ensured that the thickness that dual waves top is certain, Increasing fastness, service life is long.The height B of described dual waves is 1 6mm, and width C is 1 6mm.Described groove 4 is triangle Groove 41, the groove of triangle, compresses, stretches easily.
