Abstract
The utility model relates to an elastic extending and retracting shoe tree, which includes a front support and a heel part, wherein large connecting columns are manufactured on the front support and the heel part, and an extending and retracting tube is connected between the large connecting columns. The utility model is characterized in that small connecting columns are manufactured on the front support and the heel part, and a spring is connected between the small connecting columns. In the utility model, an extending and retracting mechanism with the spring is connected between the front support and the heel part, therefore, compared with an adjustable inflation shoe tree, the elastic extending and retracting shoe tree has the advantages of simple structure and good continuing effect; and compared with an extending and retracting mechanism with a plastic extending and retracting bellows only, the extending and retracting effect is better, the elastic extending and retracting shoe tree can relate to the area difficult to touch by a toe tip and the like, the support effect is good, the strength is larger, and the service life is prolonged.
Description
Technical field
The utility model relates to fillers, relates in particular to a kind of elastic telescopic fillers.
Background technology
Footwear are the most frequently used necessitys, kind is a lot, and most footwear all are afraid of to be squeezed, grown also and can be out of shape naturally standing time simultaneously, for example leather shoes, leather boots, leather sneakers etc. will directly sustain damage after vamp is squeezed on the one hand, produce concave deformation on the other hand, the while footwear have been put for a long time footwear nation and also can be out of shape naturally, and influence is used and be attractive in appearance.Therefore, people are squeezed and distortion naturally in order to prevent footwear, just put chock in footwear, and the footwear chock of morning is made by plastics or sponge, and big or small, the same typing of shape do not have self-regulation ability, and particularly toe cap etc. is located to be difficult to relate to, and support effect is not good.At this problem, the inventor once designed a kind of adjustable type inflatable shoe tree, its patent No. is zl200420082093.9, solved the non-retractable problem of original technical fillers size, but this fillers needs configuration tool when inflating, and leak easily the inflation back, and enabling capabilities is not good enough, uses trouble.Afterwards the inventor design a kind of simple in structure, length again can be according to the flexible fillers of footwear size, support and heel before its structure comprises, connect the plastic ripple telescoping tube between preceding support and the heel, but the plastic ripple telescoping tube is after being compressed, a little less than the bounce-back elongation ability, support effect is poor, cause toe cap difficulty relate to, often need in use with support and heel before the hand propelled, simultaneously this fillers is short service life.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, the elastic telescopic fillers that a kind of telescoping mechanism elasticity capacity is strong, intensity is high, support effect is good to be provided.
The technical scheme that the utility model adopted is to achieve the above object of the invention:
The elastic telescopic fillers, support and heel all are shaped on big joint pin before comprising on preceding support and the heel, connect telescoping tube between the big joint pin, it is characterized in that described preceding support and heel all are shaped on little joint pin, connect spring between the little joint pin, and spring is positioned at telescoping tube.
The utility model relates to a kind of elastic telescopic fillers, support and heel before comprising, connect elastic telescopic mechanism between preceding support and the heel with spring, compare with the adjustable type inflatable shoe tree have simple in structure, the advantage that lasting effect is good, compare with the telescoping mechanism that has only the plastic ripple telescoping tube, owing in telescoping tube, set up spring, spring rises preceding support and heel and is connected and supporting role, the spring enabling capabilities is strong, make this fillers can relate to the difficult zones that touch such as toe cap, and the maintenance holding state, even under external force extruding or weather influence footwear nation never is out of shape, and prolong service life.
Be shaped on spring clip on the described little joint pin, spring clip matches with spring, and there had spring clip to make that spring is connected with little joint pin to be more firm.
Described telescoping tube is the plastic ripple telescoping tube, further strengthens flexible effect.
The junction of described big joint pin and telescoping tube is shaped on and cooperates the plane, and big joint pin and telescoping tube are played positioning action, prevents to produce relatively between them to slide.
Support and heel are the hollow body that is made of plastics before described, have saved raw material.
Support and heel are the integral body that blowing is made before described, one-shot forming, and fabrication schedule is simple, and cost is low.
Support and heel are combination forming after the split injection moulding before described, strengthen fillers fastness and surperficial smoothness.
Described before the support and/or heel be shaped on pore, the Convenient shoe tree inner chamber in compression process exhaust and elongation process in air-breathing.

Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model elastic telescopic mechanism.
The specific embodiment
The utility model relates to a kind of elastic telescopic fillers, as Figure 1-3, the elastic telescopic fillers, support 5 and heel 6 before comprising, before all be shaped on big joint pin 2 on support 5 and the heel 6, connect telescoping tube 1 between the big joint pin 2, it is characterized in that described before support 5 and heel 6 all be shaped on little joint pin 3, connect spring 4 between the little joint pin 3, spring 4 is positioned at telescoping tube 1.Connect elastic telescopic mechanism between preceding support 5 that the utility model relates to and the heel 6 with spring 4, compare with the adjustable type inflatable shoe tree and to have advantage simple in structure, that lasting effect is good, compare with the telescoping mechanism that has only the plastic ripple telescoping tube, owing in telescoping tube, set up spring 4, support 5 is connected and supporting role with 6 of heels before 4 pairs on the spring, spring 4 enabling capabilities are strong, make this fillers can relate to the difficult zones that touch such as toe cap, and maintenance holding state, even under external force extruding or weather influence footwear nation never is out of shape, and prolong service life.Be shaped on spring clip 31 on the described little joint pin 3, spring clip 31 matches with spring 4, and there had spring clip 31 to make that spring 4 is connected with little joint pin 3 to be more firm.Described telescoping tube 1 is the plastic ripple telescoping tube, further strengthens flexible effect.The junction of described big joint pin 2 and telescoping tube 1 is shaped on and cooperates plane 32, big joint pin 2 and telescoping tube 1 are played positioning action, prevent to produce relatively between them and slide, the preceding support 5 of assurance fillers and heel 6 and coil tension spring 4 are in the same plane, and this structure also can be designed to square or en shape or groove location.Support 5 and the hollow body of heel 6 for being made of plastics have been saved raw material before described.Support 5 and heel 6 are the integral body that blowing is made before described, one-shot forming, and fabrication schedule is simple, and cost is low.Support 5 and heel 6 are combination forming after the split injection moulding before described, strengthen the smoothness on fillers fastness and surface.Described before the support 5 and/or heel 6 be shaped on pore, the Convenient shoe tree inner chamber in compression process exhaust and elongation process in air-breathing.
