Description

Novel tire for wheelchair

Technical Field

The utility model belongs to the technical field of the wheelchair tire, especially, relate to a novel tire is used to wheelchair.

Background

For the weak or inconvenient people walking on the lower limbs, it is necessary to move with the help of the wheelchair, and during the use of the wheelchair, the stability of the wheelchair is required to be high because of ensuring the comfort and safety of the patient, wherein the importance of the tire is essential.

At present traditional pneumatic tire has a cover tire and an inner tube of a tyre, and the cover tire is made by the rubber material, and the inner tube of a tyre is hollow structure, need inflate the inner tube of a tyre earlier during the use, realize the sufficient state of tire promptly and can rotate the use, nevertheless also consequently, when the contact of tire and external sharp-pointed foreign matter or collision, very easily produce flat tire gas leakage, so not only need change the tire again, improved the use cost of wheelchair, secondly still use for the patient and bring very big potential safety hazard. Solid rubber tires are also known in the prior art, and tires of such a structure are usually reduced in weight by forming round holes in the tire. But only through the mode of seting up the round hole, accomplish minimum with weight when can't accomplish to guarantee intensity, it is not practical enough.

SUMMERY OF THE UTILITY MODEL

An object of the embodiment of the utility model is to provide a novel tire is used to wheelchair aims at solving also has solid rubber tire among the prior art, and the tire of this type of structure is offered the round hole on the tire usually and is subtract heavy. But only through the mode of seting up the round hole, accomplish minimum with weight when can't accomplish to guarantee intensity, not practical enough problem.

The embodiment of the utility model provides a realize like this, a novel tire is used to wheelchair, including the tire main part, a plurality of bradyseisms holes have been seted up to the ring row in the tire main part, the bradyseism hole is oval-shaped hole, just the major axis in bradyseism hole distributes along the circumference of tire main part, just the size in bradyseism hole reduces along the radial outside-in of tire main part gradually, the metal wheel rim is installed to the inner circle of tire main part, just a plurality of mounting holes have been seted up to the ring row on the metal wheel rim, the outer lane of tire main part is provided with anti-skidding line.

According to a further technical scheme, three rings of shock absorption holes are formed in the tire main body.

According to the further technical scheme, the distance between two adjacent circles of the shock absorption holes is 2.5mm.

According to a further technical scheme, the tire main body is made of TPE (thermoplastic elastomer) elastomer materials.

According to the further technical scheme, the anti-skid lines are herringbone anti-skid lines.

The embodiment of the utility model provides a pair of novel tire is used to wheelchair adopts TPE elastomer material, and the wearability is good, and the resilience is good, and is more wear-resisting than PU foaming child, and life is of a specified duration, and the noise is little, adopts solid tire main part, has solved the problem that the child was pricked to the inflatable tyre, more saves worry in the aspect of the use. The bradyseism hole adopts oval horizontal overall arrangement, and outer lane hole is big inner ring hole little, increases lightening hole on the inner wall, arranges the pitch-row in proper order from outer lane to inner circle and has done the minimum, when guaranteeing use strength, the maximize has accomplished that the weight of tire is lighter, the effectual shock attenuation effect that increases the tire.

fig. 2 is a front view of a novel tire for a wheelchair according to an embodiment of the present invention.

In the drawings: a tire main body 1; a metal rim 2; a mounting hole 21; a cushioning hole 3; and (4) anti-skid lines.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided for the specific embodiments of the present invention.

As shown in fig. 1 and 2, for the utility model discloses a novel tire for wheelchair that embodiment provided, including tire main body 1, tire main body 1 is made by TPE elastomer material, a plurality of bradyseism holes 3 have been seted up on tire main body 1 to the ring row, bradyseism hole 3 is oval hole, just the major axis of bradyseism hole 3 distributes along the circumference of tire main body 1, just the size of bradyseism hole 3 reduces along the radial outside-in of tire main body 1 gradually, metal wheel rim 2 is installed to the inner circle of tire main body 1, just a plurality of mounting holes 21 have been seted up on metal wheel rim 2 to the ring row, the outer lane of tire main body 1 is provided with anti-skidding line 4.

The embodiment of the utility model provides an in, be provided with three rings bradyseism hole 3 on the tire main part 1, and adjacent two rings the interval in bradyseism hole 3 is 2.5mm. Adopt TPE elastomer material, the wearability is good, and the resilience is good, and is more wear-resisting than PU foaming child, and life is of a specified duration, and the noise is little, adopts solid tire main part 1, has solved the problem that the child was pricked to the pneumatic tire, saves worry more in the aspect of the use.
