Background technology
High-heeled shoes are as the symbol of fashion, deeply be subjected to liking of female consumer, but be subjected to the impact of design technology, many high-heeled shoes all are difficult to the padded coaming of space interpolation adequate thickness in narrow and small footwear, and the high-heeled shoes sole especially buffer problem of heel is perplexing shoe-making industry always.Prior art normally increases the back height of footwear, and then increases the volume in footwear chamber, in order to add padded coaming, but limited by style, and some footwear is also inapplicable.Also having a kind of way is that heel at footwear sets in advance a groove, by shoe tack heel is fixed at middle the end, this way often causes nail face of the middle end uneven, affects aesthetics, and the interpolation space of padded coaming is still less, does not reach best bradyseism effect.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem to be solved in the present invention provides the high-heeled shoes with the heel buffering of the more smooth and bradyseism better effects if of a kind of heel bookbinding connecting portion.
For this reason, high-heeled shoes with the heel buffering provided by the invention, comprise that upper, the middle end, steel collude the heart, footwear outer bottom and heel, the heel place is with the first depression, steel colludes the heart, and corresponding the first depression is bent downwardly distortion formation the second depression in the heel place, the bottom of the first depression of heel offers connecting hole, and dress passes steel with nail and colludes the heart and be connected with the connecting hole of heel, and second is filled with buffer unit in caving in.
In the high-heeled shoes with heel buffering provided by the invention, heel and steel collude the heart and jointly form depression, and therefore when the bookbinding heel, the dress at bookbinding position is difficult for projecting upwards too many with nail, make this position more smooth, wear more comfortablely, and structure is more firm.Simultaneously, the existence of depressed part can be filled more padded coaming, buffering effect can be adjusted to the best, can play preferably buffering and damping effect.
The specific embodiment
With reference to Fig. 1, shown in Figure 2, the high-heeled shoes with the heel buffering that the first embodiment of the present invention provides, comprise upper, the middle end, steel colludes the heart 3, footwear outer bottom and heel 5, heel 5 places are with the first depression 6, steel colludes the heart 3, and corresponding the first depression 6 is bent downwardly distortion formation the second depression 7 in heel 5 places, the bottom of the first depression 6 of heel offers connecting hole 9, dress passes steel with nail 8 and colludes the heart 3 and be connected with the connecting hole 9 of heel 5, be filled with buffer unit in the second depression 7, be to be filled in the padded coaming of the second depression in 7 at this buffer unit, this material can be polyurethane foam material etc.In the present embodiment, parcel steel of the middle end colludes the heart 3, and the front end that steel colludes the heart 3 is fixed at middle the end 2, and steel colludes the heart 3 certainly also can only have leading portion partly to be wrapped at middle the end, and the rear portion directly exposes above heel, and by the covering of the interior end.
With reference to Fig. 3, shown in Figure 4, the second embodiment of the present invention and the first embodiment are basic identical, its difference only is: buffer unit comprises headgear 10 and overcoat 11, headgear 10 upper ends are with supporting table 16, headgear 10 is pegged graft with overcoat 11, headgear 10 also is equipped with the clamping mechanism that prevents that both break away from overcoat 11, and headgear 10 relative overcoats 11 have certain flexible scope; Have internal thread 12 on headgear 10 inwalls, also be provided with spring 13, turning cylinder 14 is threaded with headgear 10, spring 13 is in turning cylinder 14 outboard ends, turning cylinder 14 with the external screw thread of internal thread 12 coupling, insert in the sliding sleeve 15 turning cylinder 14 rear ends, turning cylinder 14 can rotate relative to sliding sleeve 15, sliding sleeve 15 is arranged in the overcoat 11, and sliding sleeve 15 relative overcoats 11 are circumferentially fixing; The supporting table 16 of buffer unit protrudes from outside the depression 6.The buffer unit that the present embodiment provides adopts the screw-internal thread fit in screw rod 17 and the headgear 10, headgear 10 is further exerted pressure to screw rod 17 in the process that is extruded, because screw rod 17 can rotate relative to sliding sleeve, screw rod 17 rotates and impels headgear 10 to move down along the tendency of screw thread relative to headgear 10 in this process, because being the modes with threaded engagement, the movement of headgear 10 limits, no matter the pressure that closes that therefore headgear 10 is subject to is that the large or little headgear 10 that can both impel is slowly mobile, and the be stressed impact of size of its translational speed is very little; Spring 13 in the headgear 10 can make and close a buffer promote headgear 10 when being closed pressure in addition, makes its reinstatement, can continue to provide cushioning effect power for the heel place by above action, and durable degree is better than filling padded coaming.
In above-mentioned the second embodiment, turning cylinder 14 is made of screw rod 17 and slide bar 18 two parts, on the screw rod 17 with external screw thread, screw rod 17 is threaded with headgear 10, one end of slide bar 18 and sliding sleeve 15 are pegged graft, the other end of slide bar 18 and screw rod 17 end contacts, and both rubbing surfaces cooperate; Screw rod 17 ends are with rubber ring 19, and slide bar 18 ends are with anti-skidding projection 20, the rubber ring 19 of screw rod 17 and anti-skidding projection 20 tight fits of slide bar 18.
In above-mentioned the second embodiment, be marked with resistance oil in the sliding sleeve 15, slide bar 18 cover has sealing ring 21, sealing ring 21 cooperates with sliding sleeve 15 inwalls, resistance oil can be sealed thus headgear 10 and in, so that better cushioning effect to be provided; With steel ball cushion cap 22, steel ball 23 is arranged between steel ball cushion cap 22 and the spring 13 screw rod 17 near an end of spring 13, and steel ball 23 cooperates with spring 13 can prevent that spring 13 and the end of screw rod 17 from more rubbing action occuring; The formation that prevents the clamping mechanism that headgear 10 and overcoat 11 break away from is: be provided with screens projection 24 on headgear 10 outer peripheral faces, be provided with the chute that mates with screens projection 24 on overcoat 11 inwalls, be provided with the limited block 25 of smooth excessiveness on the chute.
