Abstract
The invention provides a child bike tire. The child bike tire comprises an inner tire, an outer tire and a wheel rim, wherein an arc-shaped segment section which can be conveniently supported on ground is formed on the outer side of a segment section of the outer tire, the arc-shaped segment section comprises two arc-shaped segments which are symmetrical in a radial direction and a straight segment connecting the two arc-shaped segments, the straight segment is symmetrical in the radial direction, and a plurality of annular slots which are convenient to increase friction force are formed on the circumference of the outer tire positioned on the straight segment. The child bike tire provided by the invention can improve the stability of a bike when the bike is supported on the ground on the premise of realizing free driving action, and can particularly improve safety for child driving, thereby having using values.
Description
Technical field
The invention belongs to bike tyre, particularly the transformation of child's bicycle tire.
Background technology
In prior art, bike tyre is made up of (as shown in Figure 1) the inner tube of a tyre, cover tire and steel ring, and cover tire is installed on steel ring, and the inner tube of a tyre is that air tyre is installed between cover tire and steel ring, and cover tire outer peripheral face forms thicker bearing surface, is convenient to support ground and rides.For child's bicycle, wheel rim smaller (general 10-16 inch), children hold bicycle directional ability to be had more weak, often can fall down by bike, can provide a kind of can the tire of light safety and stability again by bike, be the object that technical personnel is asked most always.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of baby carriage tires, under satisfied freedom of movement prerequisite by bike, improving the stability that driving supports ground, especially for children by bike, improve safety, have use value.
Technical scheme of the present invention is achieved in that a kind of baby carriage tires, comprise the inner tube of a tyre, cover tire and steel ring, the segmental arc cross section being convenient to support ground is formed outside the section cross section of this cover tire, this segmental arc cross section is made up of radial direction two segmental arcs symmetrically, the flat segments that connects this two segmental arc, and this flat segments radial direction symmetrically.
As a further improvement on the present invention, this outer tread ring week be positioned in this flat segments forms the annular groove that many are convenient to increase friction force.
As a further improvement on the present invention, in this segmental arc cross section, radian corresponding to this flat segments is 20 degree.
Advantageous Effects of the present invention is: described baby carriage tires comprises the inner tube of a tyre, cover tire and steel ring, the segmental arc cross section being convenient to support ground is formed outside the section cross section of this cover tire, and this segmental arc cross section is made up of radial direction two segmental arcs symmetrically, the flat segments that connects this two segmental arc, this flat segments radial direction symmetrically, adds by this flat segments the stability that children ride like this.
Accompanying drawing explanation
The section schematic cross-section that Fig. 1 is tire described in prior art;
The section schematic cross-section that Fig. 2 is tire described in the present invention.
Explanation is supplemented as follows to accompanying drawing:
1---steel ring 41,42---segmental arc
2---cover tire 43---flat segments
3---inner tube of a tyre 431---annular groove
4---segmental arc cross section
Detailed description of the invention
Composition graphs 2, do to describe in detail as follows:
A kind of baby carriage tires, comprise the inner tube of a tyre 3, cover tire 2 and steel ring 1, outside the section cross section of this cover tire 2 (namely to should the outer peripheral face of cover tire) form the segmental arc cross section 4 being convenient to support ground, this segmental arc cross section 4 by radial direction two segmental arcs 41 symmetrically, 42, the flat segments 43 that connects this two segmental arc 41,42 forms, this flat segments 43 radial direction is symmetrically.
When riding to increase, ground effect grabbed by tire, and this cover tire 2 ring week be positioned in this flat segments 43 forms the annular groove 431 that many are convenient to increase friction force.
More specifically, in this segmental arc cross section 4, the interval radian of this flat segments 43 correspondence is 40-60 degree (angles as in Fig. 2 folded by two dotted lines).
Claims (3)
1. a baby carriage tires, comprise the inner tube of a tyre (3), cover tire (2) and steel ring (1), the segmental arc cross section (4) being convenient to support ground is formed outside the section cross section of this cover tire (2), it is characterized in that, this segmental arc cross section (4) is made up of radial direction two segmental arcs symmetrically (41,42), the flat segments (43) that connects this two segmental arc (41,42), and this flat segments (43) radial direction symmetrically.
2. a kind of baby carriage tires as claimed in claim 1, is characterized in that, this cover tire (2) the ring week be positioned in this flat segments (43) forms the annular groove (431) that many are convenient to increase friction force.
3. a kind of baby carriage tires as claimed in claim 1, is characterized in that, in this segmental arc cross section (4), the interval radian of this flat segments (43) correspondence is 40-60 degree.
