Abstract

The utility model discloses a nest-hole type non-inflatable tyre which is composed of an inner ring (1), an outer ring and a nest-hole sandwich layer (4) composed of a vibration damping body with a hollow cylindrical body (3) between the inner ring and the outer ring. The utility model is characterized in that the elastic restoring force of the hollow cylindrical body is utilized by the vibration damping body to realize vibration damping and buffering; the utility model can be utilized without inflation, which not only has good vibration damping effect, but also avoids various defects of soild tyres.

Description

The nest cellular type does not have the gas tire

The utility model belongs to tire, and especially cycle tyre is made the field.

Present bicycle generally all adopts cover tire to add the basic structure of inflatable inner tube, owing to thrusting of the wearing and tearing of the inner tube of a tyre, hard thing, often causes inner tube of a tyre gas leakage, brings very big inconvenience for user's daily life.Though, adopt the solid rubber tire to address this problem to a certain extent, solid tyre uses the comparison heaviness, and the elastomeric material of itself is also more, mounting or dismounting inconvenience.

The purpose of this utility model is a kind of good and tire simple in structure of inflatable inner tube, damping effect that need not of design.

The purpose of this utility model realizes by following design.

The nest cellular type does not have the gas tire, by inner ring, outer ring and be clipped in inner ring and the outer ring between the nest hole interlayer that constitutes by open column shape body shock reducing structure formed.

After having adopted structure as above, be clipped in nest hole interlayer between the inside and outside circle and utilize the elastic resilience of an open column shape shock reducing structure will be from the vibrations and the impact absorption of outer ring, because nest hole interlayer is a hollow structure, whole tire be in light weight, and materials are economized.

Description of drawings is as follows.

Fig. 1 is the constructional drawing (the nest hole interlayer part of only drawing, other parts are omitted) of embodiment of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

Can see in Fig. 1 and Fig. 2, make inner ring 1 and outer ring 2 by elastomeric material, be clipped in the nest hole interlayer of being made up of some hollow cylinder shape shock reducing structures 34 between inner ring and the outer ring, shock reducing structure 2 can make with rubber and other material with certain elastic-restoring force.That the hollow cylindrical of shock reducing structure can be is cylindrical, honeycomb, elliptical cylinder-shape etc., is cylindrical in this example.Nest hole interlayer 4 can be made of (having drawn one deck in this example) the hollow shock reducing structure of multilayer.

Inner ring 1, outer ring 2 and nest hole are separable, but also the pressing mold once-forming is an one.For ease of the mounting or dismounting of carcass, also for inner ring is more mildly fitted with bicycle rim, can on inner ring 1, offer circular groove 5 simultaneously.Opened the twice circular groove in this example.

The cross sectional shape of inner ring 1 can design multiple variation with the difference of used bicycle ring cross-section shape, so that inner ring 1 can be with rim be chimeric well voluntarily.

Tire of the present utility model is compared with traditional tire, on fetalism and structure, all have bigger change, need not to be provided with again inflatable inner tube, be not afraid of the bore spine of hard thing such as nail, cullet, the various inconvenience of having avoided inflation tyre gas leakage to bring, convenient widely bicycle user.

Utilize basic scheme of the present utility model, choice structure material suitably, range of use of the present utility model also can expand on the tire of three-wheel vehicle, motor bike etc.

Claims

1, a kind of nest cellular type does not have the gas tire, it is characterized in that, by inner ring (1), outer ring (2) and be clipped in inner ring and the outer ring between the nest hole interlayer (4) that constitutes by open column shape body shock reducing structure (3) formed.

2, nest cellular type according to claim 1 does not have the gas tire, it is characterized in that, inner ring (1), outer ring (2) and nest hole interlayer (4) can be an integral body by the pressing mold one-shot forming.

3, nest cellular type according to claim 1 does not have the gas tire, it is characterized in that, open column shape snubber block (3) is cylindrical.

4, nest cellular type according to claim 1 does not have the gas tire, it is characterized in that, offers circular groove (5) on the inner ring (1).
