Abstract

The utility model relates to an inner tire of landing mat for jumping, which consists of a bottom layer, a middle-lower layer, middle-upper layer and an upper layer up and down in sequence; every two neighboring layers are firmly stuck together through bond; both the middle-lower layer and the middle-upper layer are manufactured by a plurality of parallel strip normal plastic foaming bodies which are provided with clearances; and the strip normal plastic foaming bodies of the middle-lower layer and the strip normal plastic foaming bodies of the middle-upper layer are vertically crossed. The strip normal plastic foaming bodies of the middle-lower layer and the strip normal plastic foaming bodies of the middle-upper layer in the inner tire of landing mat for jumping are mutually and vertically arranged, which leads the inner tire to be strained more reasonably relatively to alignment; space is generated through the spacing arrangement of normal materials, which is equivalent to remove partial material and generates the effect of reducing the integral rigidity of the inner tire, thereby recovering the shortage of large rigidity of normal material, and achieving the flexibility equal to special plastic foaming body. However, as the cost is reduced and the price is proper, the inner tire of landing mat for jumping is very suitable to be popularized and applied in large scales.

Description

The high jump landing mat inner tube of a tyre

Technical field

The utility model relates to a kind of sports equipment, especially a kind of high jump landing mat inner tube of a tyre.

Background technology

High jump is divided into fosubry flop and Jackstay type high jump at present, and two kinds of high jumps all need to be provided with satisfactory landing mat at its landing area.The landing mat performance is neither too hard, nor too soft, and the sportsman is landed certain buffering, protects the sportsman can not fall pain tumble injury effectively.

The existing landing mat inner tube of a tyre needs special plastic material to form through special technology foaming, and the whole inner tube of a tyre is continuous, a uniform plasticity foaming body, and cost is very expensive, is unfavorable for promoting the use of; If use conventional material to form through foaming, the problem that its hardness is big can't resolve always, also is not suitable for using.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of neither too hard, nor too soft, save cost, can satisfy the high jump landing mat inner tube of a tyre of instructions for use again.

For achieving the above object, the utility model adopts following technical proposals:

A kind of high jump landing mat inner tube of a tyre, it is from bottom to top successively by bottom, middle lower floor, form with the upper strata at the middle and upper levels, between described each adjacent two layers by the adhesive good bond together; Lower floor and being made by the conventional plasticity foaming bodies of some strips that be arranged in parallel at the middle and upper levels in described, and conventional plasticity foaming body of the strip of middle lower floor and the routine of strip at the middle and upper levels plasticity foaming body square crossing setting with gap.

Described bottom and upper strata by continuous, the plasticity foaming body is made uniformly.

Middle lower floor in the utility model, at the middle and upper levels owing to used the conventional plasticity foaming body of strip interstitial structure, the one, played the effect of special plasticity foaming body with conventional plasticity foaming body, the 2nd, conventional plasticity foaming body has also been carried out saving, be to kill two birds with one stone.

Middle lower floor in the utility model, the conventional plasticity foaming body in strip gap are at the middle and upper levels carried out mutual arranged vertical, make inner tube of a tyre more reasonable stress with respect to arranging in the same way; Produced the space by being spaced of conventional material, be equivalent to remove the part material, the effect of its generation is that the integral hardness of the inner tube of a tyre reduces, thereby has remedied the big deficiency of conventional material hardness, has reached and the equal soft or hard degree of special plasticity foaming body.But moderate because its cost reduces, be suitable on a large scale very much and apply.

The utility model is on probation through the sportsman, and reaction is good, thinks to reach instructions for use fully.

Description of drawings

Fig. 1 is the local figure in the utility model cross section;

Fig. 2 is that A-A schemes to analysing and observe the part among Fig. 1;

Fig. 3 is a lower floor and arrange schematic isometric at the middle and upper levels in the utility model;

Wherein 1, the upper strata, 2, at the middle and upper levels, 3, middle lower floor, 4, bottom.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Among Fig. 1-3, the high jump landing mat inner tube of a tyre, its from bottom to top successively by bottom 4, middle lower floor 3, at the middle and upper levels 2 and upper strata 1 form, between described each adjacent two layers by the adhesive good bond together;

Lower floor

3 and 2 being made at the middle and upper levels in described, and conventional plasticity foaming body of the strip of middle

lower floor

3 and 2 strip routine plasticity foaming body square crossing setting at the middle and upper levels by the conventional plasticity foaming bodies of some strips that be arranged in parallel with gap.

Described bottom 4 and upper strata 1 by continuous, the plasticity foaming body is made uniformly.

Middle lower floor 3 in the utility model, at the middle and upper levels 2 owing to used the conventional plasticity foaming body of strip interstitial structure, the one, played the effect of special plasticity foaming body with conventional plasticity foaming body, the 2nd, conventional plasticity foaming body has also been carried out saving, be to kill two birds with one stone.

Middle lower floor 3 in the utility model, the conventional plasticity foaming body in 2 strip gap is carried out mutual arranged vertical at the middle and upper levels, makes inner tube of a tyre more reasonable stress with respect to arranging in the same way; Produced the space by being spaced of conventional material, be equivalent to remove the part material, the effect of its generation is that the integral hardness of the inner tube of a tyre reduces, thereby has remedied the big deficiency of conventional material hardness, has reached and the equal soft or hard degree of special plasticity foaming body.But moderate because its cost reduces, be suitable on a large scale very much and apply.

Claims

1. high jump landing mat inner tube of a tyre is characterized in that: it is from bottom to top successively by bottom, middle lower floor, form with the upper strata at the middle and upper levels, between described each adjacent two layers by the adhesive good bond together; Lower floor and being made by the conventional plasticity foaming bodies of some strips that be arranged in parallel at the middle and upper levels in described, and conventional plasticity foaming body of the strip of middle lower floor and the routine of strip at the middle and upper levels plasticity foaming body square crossing setting with gap.

2. the high jump landing mat inner tube of a tyre according to claim 1 is characterized in that: described bottom and upper strata by continuous, the plasticity foaming body is made uniformly.
