Abstract
This utility model discloses a kind of footwear sole construction having back heel shock-absorbing function, and including the end in EVA and damping projection, in EVA, the heel region at the end is provided with the damping groove of concave downward, and the sidewall of damping groove is provided with annular wall trench；Damping projection bottom is the outward extending annular flange flange of radial level, damping projection is inserted in damping groove and annular wall trench, and be connected between damping projection bottom and damping groove bottom wall and have stage clip, under non-stress annular flange flange and annular wall trench roof abut against and and annular wall groove bottom wall between leave deformation spacing, so that damping projection has ideal buffering deformation space under heel stress weight bearing situations, absorb componental movement energy by deformation and rebound to foot portion after going power, damping performance is good and energy rebound value is the highest, additionally can make in Repeated Compression springback process damping projection and annular flange flange all the time in damping groove and annular wall trench without departing from.
Description
Technical field
This utility model relates to footwear technical field, particularly relates to a kind of footwear sole construction having back heel shock-absorbing function.
Background technology
Showing according to biomechanics Research, most people are first to land with rear heel, and give on the initial stage ground of landing
The counteracting force of foot reaches 3～8 times of user's own body weight, if this impulsive force can not effectively disperse to reduce, uses in the course of time
Family is easy for tired impaired.To this end, the shock-absorbing function at spring heel position is a very important ring in the middle of footwear design.
Utility model content
The purpose of this utility model is to provide a kind of footwear sole construction having back heel shock-absorbing function, effectively promotes spring heel
The damping performance at position.
The technical solution that this utility model uses is:
A kind of footwear sole construction having back heel shock-absorbing function, including the end in EVA and damping projection, the end and the rear foot in described EVA
With being provided with the damping groove of concave downward at opposite position, the sidewall of described damping groove is provided with annular wall trench；Described subtract
Shake projection bottom be radial level stretch out arrange annular flange flange, described damping projection is inserted in damping groove and annular wall
In groove, and it is connected between described damping projection bottom and damping groove bottom wall and has stage clip, described convex annular under non-stress
Edge and annular wall trench roof abut against and and annular wall groove bottom wall between leave deformation spacing.
Preferably, it is provided with limited post protruding upward, described pressure at described damping bottom portion of groove and stage clip opposite position
Spring is set in outside limited post, and leaves deformation spacing between described limited post top and damping projection bottom surface.
Preferably, described annular flange flange bottom surface circumference uniform intervals is provided with two or more elastomer block, not
Under stress, primary leading between described elastomer block bottom surface and annular wall groove bottom is less than the maximum distortion length of stage clip.
Preferably, it is respectively equipped with annular groove, at pressurized shape at described annular wall groove bottom wall and elastomer block opposite position
Under state, described elastomer block presses in annular groove.
Preferably, described elastomer block is block rubber.
The beneficial effects of the utility model: owing to heel position is provided with damping groove in EVA, also set in damping groove
Having an annular wall trench, in damping groove and annular wall trench, adaptation is equiped with damping projection, and damping projection bottom surface and damping groove-bottom
Between wall connect have stage clip, the annular flange flange of damping projection bottom under non-stress with annular wall trench roof abut against and with
Deformation spacing is left, so that damping projection has ideal under heel stress weight bearing situations between annular wall groove bottom wall
Buffering deformation space, absorb componental movement energy rebound to foot after going power by deformation, damping performance is good and energy
Regressand value is the highest, and the annular flange flange additionally, due to damping projection is connected in the annular wall trench of damping groove so that repeatedly pressing
During retraction bullet damping projection all the time in damping groove without outer jumping, annular flange flange all the time annular wall trench in without
Departing from, each several part such as damping groove, annular wall trench, damping projection, annular flange flange and stage clip interacts, and collaborative strengthens, and composes
Give the damping performance that this utility model spring heel position is excellent.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1-2, the present embodiment provides a kind of footwear sole construction having back heel shock-absorbing function, including the end in EVA 20 He
Damping projection 10.Described EVA is provided with at the end 20 and rear heel opposite position the damping groove 30 of concave downward, described damping
The sidewall of groove 30 is provided with annular wall trench 40.Described damping projection 10 bottom be radial level stretch out arrange convex annular
Edge 11, described damping projection 10 is inserted in damping groove 30 and annular wall trench 40, and described damping projection 10 bottom and damping
Connecting between groove 30 diapire and have stage clip 50, under non-stress, described annular flange flange 11 abuts against with annular wall trench 40 roof
And and annular wall trench 40 diapire between leave deformation spacing.
In the present embodiment, bottom described damping groove 30 with stage clip 50 opposite position at be provided with protruding upward spacing
Post 31, described stage clip 50 is set in outside limited post 31, and leaves change between described limited post 31 top and damping projection 10 bottom surface
Shape spacing, by this limited post 31 ensure stage clip 50 in Repeated Compression springback process will not transposition, all the time with damping projection 10
Vertical connection.
In the present embodiment, described annular flange flange 11 bottom surface circumference uniform intervals is provided with two or more elasticity
Block 60, described elastomer block 60 is block rubber, and described annular wall trench 40 diapire is respectively equipped with ring at elastomer block 60 opposite position
Connected in star 41, the most described elastomer block 60 presses in annular groove 41, described elastomer block under non-stress
Primary leading between 60 bottom surfaces and annular wall trench 40 bottom surface is less than the maximum distortion length of stage clip 50, so that at pressurized shape
Under state, described elastomer block 60 i.e. can contact with annular wall trench 40 base pressure before stage clip 50 not yet reaches maximum distortion degree
And participate in bumper and absorbing shock process, so combine the material at the end 20 itself in elastomer block 60 and stage clip 50 and damping projection 10 and EVA
Material shock absorbing characteristics is greatly enhanced the damping effect of the present embodiment spring heel.
