Abstract
The utility model discloses a bassinet has pneumatic tire that exempts from of inner bag aims at providing a simple structure, long service life, the risk of do not have gas leakage, blowing out, and can effectively solve the whole pneumatic tire that exempts from by rubber integrated into one piece weight is big, manufacturing cost is high problem of current bassinet solid tyre. It includes the cover tire and sets up the solid inner bag child of elasticity in the cover tire. The solid inner bag child of elasticity is EVA inner bag child.
Description
Technical field
This utility model relates to a kind of baby carriage tires, and being specifically related to a kind of perambulator has the non-inflatable tyre of inner bag.
Background technology
Baby carriage tires is divided into pneumatic tire and solid tyre.Pneumatic tire is divided into the pneumatic tire of the inner tube of a tyre and tubeless pneumatic tire, pneumatic tire shock-absorbing, good buffer effect, and comfortableness is high；But it needs inflation, the risk there is gas leakage, blowing out.
Solid tyre is a kind of tire corresponding with pneumatic tire, its carcass be one overall solid.Solid tyre is generally divided into adhesive type and non-adhesive type two kinds, and the former refers to that rubber directly vulcanizes the tire on wheel rim, and the latter is fixed on the tire on wheel rim after referring to sulfuration again.Solid tyre length in service life, the risk that there is not gas leakage, blow out；But common perambulator solid tyre is overall one-body molded by rubber, and its weight is big, cost of material is high, adds production cost.
Utility model content
The purpose of this utility model is the deficiency in order to overcome baby carriage tires in prior art to exist, it is provided that a kind of perambulator has the non-inflatable tyre of inner bag, and its simple in construction, service life are long, the risk there is not gas leakage, blowing out；And can effectively solve the problem that existing perambulator solid tyre entirety is big by the one-body molded weight of rubber, production cost is high.
The technical solution of the utility model is:
A kind of perambulator has the non-inflatable tyre of inner bag, including cover tire and the elastic solid inner bag tire that is arranged in cover tire.
The non-inflatable tyre simple in construction of this programme, service life are long, the risk there is not gas leakage, blowing out；And owing to tire is made up of cover tire and the elastic solid inner bag tire that is arranged in cover tire, and elastic solid inner bag tire can use the light weight such as EVA, good springiness, the material of low cost to make to material requirement is relatively low, can effectively solve the problem that existing perambulator solid tyre entirety is big by the one-body molded weight of rubber, production cost is high.
As preferably, elastic solid inner bag tire is EVA inner bag tire.
As preferably, also include wheel rim.
As preferably, the lateral surface of wheel rim has annular mounting groove, and the bottom surface of this annular mounting groove is provided with some limited posts, and the medial surface of described elastic solid inner bag tire is provided with some and limited post spacing hole one to one, and limited post is plugged in spacing hole.
Together with being press fit into by interference fit due to cover tire and elastic solid inner bag tire and wheel rim, cover tire and elastic solid inner bag tire expanded by heating may cause cover tire and elastic solid inner bag tire and wheel rim slipping ring；This programme improves for this problem, is coordinated by the spacing hole of the limited post of wheel rim with elastic solid inner bag tire, makes wheel rim be connected as a single entity with elastic solid inner bag tire, it is to avoid produce slipping ring phenomenon between wheel rim and elastic solid inner bag tire；Simultaneously because the contact area between cover tire and elastic solid inner bag tire is big, and together expanded by heating, thus slipping ring phenomenon will not occur between cover tire and elastic solid inner bag tire, cover tire and elastic solid inner bag tire thus can be avoided to produce slipping ring phenomenon with wheel rim.
As preferably, limited post radially extending along wheel rim.
As preferably, the medial surface of elastic solid inner bag tire abuts against on the bottom surface of annular mounting groove, and the bottom surface of described annular mounting groove is provided with some double wedges.The double wedge of this programme can increase the frictional force between wheel rim and elastic solid inner bag tire, can be prevented effectively between wheel rim and elastic solid inner bag tire generation slipping ring phenomenon further.
As preferably, wheel rim is plastics wheel rim.
As preferably, cover tire is rubbery cover tyre.
The beneficial effects of the utility model are: have simple in construction, service life long, the feature of the risk there is not gas leakage, blowing out；And can effectively solve the problem that existing perambulator solid tyre entirety is big by the one-body molded weight of rubber, production cost is high.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation that perambulator of the present utility model has the non-inflatable tyre of inner bag.
In figure: cover tire 1, elastic solid inner bag tire 2, wheel rim 3, annular mounting groove 31, limited post 32.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of perambulator has the non-inflatable tyre of inner bag to include cover tire 1, the elastic solid inner bag tire 2 being arranged in cover tire and wheel rim 3.Cover tire is rubbery cover tyre.Elastic solid inner bag tire is EVA inner bag tire.Wheel rim is plastics wheel rim.The lateral surface of wheel rim has annular mounting groove 31.Cover tire is arranged on wheel rim.
The medial surface of elastic solid inner bag tire abuts against on the bottom surface of annular mounting groove.The bottom surface of annular mounting groove is provided with some limited posts 32.Limited post radially extending along wheel rim.The bottom surface of annular mounting groove is provided with some double wedges.The medial surface of elastic solid inner bag tire is provided with some and limited post spacing hole one to one, and limited post is plugged in spacing hole.
The non-inflatable tyre simple in construction of the present embodiment, service life are long, the risk there is not gas leakage, blowing out；And owing to tire is made up of cover tire and the elastic solid inner bag tire that is arranged in cover tire, and elastic solid inner bag tire can use the light weight such as EVA, good springiness, the material of low cost to make to material requirement is relatively low, can effectively solve the problem that existing perambulator solid tyre entirety is big by the one-body molded weight of rubber, production cost is high.
