Background technology
High-heeled shoes are as the symbol of fashion, dark liking by female consumer, but by the impact of design technology, many high-heeled shoes are all difficult to space in narrow and small footwear and add the padded coaming of adequate thickness, the buffer problem of high-heeled shoes sole especially heel annoyings shoe-making industry always.Prior art normally increases the back height of footwear, and then increases the volume in footwear chamber, to add padded coaming, but limit by style, some footwear is also inapplicable.A kind of way is also had to be pre-set a groove at the heel of footwear, be fixed on by shoe tack by heel, this way often causes nail face, the middle end uneven, affects aesthetics at middle the end, and the interpolation space of padded coaming is still less, do 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 is to provide the high-heeled shoes of a kind of heel bookbinding connecting portion more smooth and band heel of bradyseism better effects if buffering.
For this reason, the high-heeled shoes of band heel buffering provided by the invention, comprise upper, the middle end, steel the hook heart, footwear outer bottom and heel, heel place is with the first depression, the steel hook heart is bent downwardly distortion formation second in heel place correspondence first depression and caves in, the bottom of the first depression of heel offers connecting hole, and dress hooks the heart with nail through steel and is connected with the connecting hole of heel, is filled with buffer unit in the second depression.
In the high-heeled shoes of band heel buffering provided by the invention, heel and steel hook the heart and jointly form depression, and therefore when binding heel, the dress at bookbinding position not easily projects upwards too many with nail, make this position more smooth, wear more comfortable, and structure is more firm.Meanwhile, the existence of depressed part can fill more padded coaming, buffering effect can be adjusted to the best, can play good buffering and damping effect.
Detailed description of the invention
With reference to Fig. 1, shown in Fig. 2, the high-heeled shoes of the band heel buffering that the first embodiment of the present invention provides, comprise upper, the middle end, steel hooks the heart 3, footwear outer bottom and heel 5, heel 5 place is with the first depression 6, the steel hook heart 3 is bent downwardly distortion formation second in heel 5 place correspondence first depression 6 and caves in 7, the bottom of the first depression 6 of heel offers connecting hole 9, dress hooks the heart 3 with nail 8 through steel and is connected with the connecting hole 9 of heel 5, buffer unit is filled with in second depression 7, be be filled in the padded coaming in the second depression 7 at this buffer unit, this material can be polyurethane foam material etc.In the present embodiment, parcel steel of the middle end hooks the heart 3, and the front end that steel hooks the heart 3 is fixed at middle the end, and certain steel hooks the heart 3 also can only have front section to be wrapped at middle the end, and rear portion is directly exposed above heel, and is covered by the interior end.
With reference to shown in Fig. 3, Fig. 4, the second embodiment of the present invention is substantially identical with the first embodiment, its difference is only: buffer unit comprises headgear 10 and overcoat 11, headgear 10 upper end is with supporting table 16, headgear 10 and overcoat 11 grafting, headgear 10 and overcoat 11 are also equipped with the clamping mechanism preventing both from departing from, and headgear 10 relatively overcoat 11 has certain telescopic extensions; Headgear 10 inwall has internal thread 12, also be provided with spring 13, turning cylinder 14 is threaded with headgear 10, spring 13 is in turning cylinder 14 outboard end, turning cylinder 14 is with the external screw thread mated with internal thread 12, and turning cylinder 14 rear end is inserted in sliding sleeve 15, and turning cylinder 14 can rotate relative to sliding sleeve 15, sliding sleeve 15 is arranged in overcoat 11, and overcoat 11 circumference is fixing relatively for sliding sleeve 15; The supporting table 16 of buffer unit protrudes from outside depression 6.The buffer unit that the present embodiment provides adopts screw rod 17 and the screw-internal thread fit in headgear 10, headgear 10 is made to apply pressure to screw rod 17 further in the process be extruded, because screw rod 17 can rotate relative to sliding sleeve, screw rod 17 rotates relative to headgear 10 and impels headgear 10 to move down along the tendency of screw thread in this process, movement due to headgear 10 limits in the mode of threaded engagement, no matter what therefore headgear 10 was subject to close, a pressure large or littlely can both impel headgear 10 slowly movement, and the be stressed impact of size of its translational speed is very little; Spring 13 in addition in headgear 10 can make to close a buffer and be promoted headgear 10 when not closing pressure, make it restore to the original state, can continue to provide cushioning effect power for heel place by above action, and robustness is better than filling padded coaming.
In above-mentioned the second embodiment, turning cylinder 14 is made up of, with external screw thread on screw rod 17 screw rod 17 and slide bar 18 two parts, screw rod 17 is threaded with headgear 10, one end of slide bar 18 and sliding sleeve 15 grafting, the other end of slide bar 18 and screw rod 17 end contact, both rubbing surfaces coordinate; Screw rod 17 end with rubber ring 19, slide bar 18 end with non-slip bumps 20, non-slip bumps 20 tight fit of the rubber ring of screw rod 17 19 and slide bar 18.
In above-mentioned the second embodiment, be marked with resistance oil in sliding sleeve 15, slide bar 18 cover has sealing ring 21, and sealing ring 21 coordinates with sliding sleeve 15 inwall, resistance oil can be enclosed in thus headgear 10 and within, to provide better cushioning effect; Screw rod 17 is close to one end of spring 13 with steel ball cushion cap 22, and steel ball 23 is arranged between steel ball cushion cap 22 and spring 13, and steel ball 23 coordinates with spring 13 and can prevent spring 13 from the end of screw rod 17, rubbing action more occurring; The formation of the clamping mechanism preventing headgear 10 and overcoat 11 from departing from is: headgear 10 outer peripheral face is provided with screens projection 24, overcoat 11 inwall is provided with the chute mated with screens projection 24, chute is provided with the limited block 25 of smooth excessiveness.
