Description

Shock-proof wheel for wheelchair

Technical Field

The utility model relates to a wheel field of moving away to avoid possible earthquakes especially relates to a wheel of moving away to avoid possible earthquakes for wheelchair.

Background

The shock-absorbing wheel is widely applied to the industry fields of vehicles, industrial equipment, medical equipment and the like, and has the main function of improving the shock-absorbing capacity of the wheel, so that the stability and the comfort of the vehicles and the equipment are better.

But some on the existing market move away to avoid possible earthquakes the structure of wheel comparatively complicated, production and installation are inconvenient, and some move away to avoid possible earthquakes the wheel and rely on the material and the structure of tire to move away to avoid possible earthquakes, and the effect of moving away to avoid possible earthquakes is relatively poor, and some move away to avoid possible earthquakes the wheel and can't reach the spacing of stroke of moving away to avoid possible earthquakes in addition.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a wheel of moving away to avoid possible earthquakes for wheelchair has reliable performance height, stability height, compact structure, the effectual advantage of moving away to avoid possible earthquakes, has extensive market prospect in the application and the popularization of wheel of moving away to avoid possible earthquakes simultaneously.

In order to solve the technical problem, the utility model discloses a technical scheme be:

there is provided a suspension wheel for a wheelchair, comprising: a roller, a shock absorbing spring, a fork arm, an upper shock absorbing seat and a lower shock absorbing seat,

the fork arms are arranged on two sides of the bottom surface of the lower shock absorbing seat, the idler wheel is movably connected with the two fork arms through a wheel shaft, the upper shock absorbing seat is rotatably connected with the lower shock absorbing seat, a first groove is formed in the bottom of the upper shock absorbing seat, third grooves which are matched with the lower shock absorbing seat and are limited are formed in two sides of the first groove, a second groove is formed in the top of the lower shock absorbing seat, and a spring groove used for placing the shock absorbing spring is formed by the first groove and the second groove.

In a preferred embodiment of the present invention, the top surface of the upper shock absorbing base is provided with shock absorbing pads.

In a preferred embodiment of the present invention, the top surface of the upper shock absorbing base is provided with a wheel connecting shaft.

In a preferred embodiment of the present invention, the roller is rotatably connected to the yoke.

In a preferred embodiment of the present invention, the upper shock absorbing base and the lower shock absorbing base are movably connected by a connecting shaft.

In a preferred embodiment of the present invention, the upper limiting surface of the first groove forms a limiting included angle with the top surface of the lower suspension seat.

In a preferred embodiment of the present invention, the spring slot is provided with positioning blocks on the top and bottom surfaces thereof for fixing the spring.

The utility model has the advantages that: through the cooperation of last seat of moving away to avoid possible earthquakes, lower seat of moving away to avoid possible earthquakes and the spring of moving away to avoid possible earthquakes for the shock-proof performance of wheel obtains improving, and these three still have limiting displacement simultaneously, are difficult to wearing and tearing, have improved the stability and the practicality of wheel.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:

FIG. 1 is a schematic side view of a shock absorbing wheel according to a preferred embodiment of the present invention;

fig. 2 is a schematic cross-sectional view of a preferred embodiment of the shock absorbing wheel of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, an embodiment of the present invention includes:

a shock absorbing wheel for a wheelchair comprising: the shock absorbing device comprises a roller 1, a shock absorbing spring 2, a fork arm 3, an upper shock absorbing seat 4 and a lower shock absorbing seat 5, wherein the upper shock absorbing seat is movably connected with the lower shock absorbing seat through a connecting shaft, and the top surface of the upper shock absorbing seat is provided with a shock absorbing gasket 10 and a wheel connecting shaft 11.

The yoke set up in the both sides of seat bottom surface of moving away to avoid possible earthquakes down, the gyro wheel passes through the shaft and two yoke swing joint, the bottom of going up the seat of moving away to avoid possible earthquakes is provided with first recess 6, the both sides of first recess be provided with the spacing third recess 8 of seat cooperation of moving away to avoid possible earthquakes down, the last spacing face of first recess with the top surface of the seat of moving away to avoid possible earthquakes down forms a spacing contained angle, lifts on the seat of moving away to avoid possible earthquakes down when last spacing face contact, carries on spacingly to the seat of moving away to avoid possible earthquakes down, prevents that the seat of moving away to avoid possible earthquakes down excessively rises and makes spring, the seat of moving away to avoid.

The top of lower shock absorber seat is provided with second recess 7, first recess with the second recess constitutes and is used for placing the spring groove of shock absorber spring.

The top surface and the bottom surface of the spring groove are provided with positioning blocks 9 for fixing the spring, so that the spring is prevented from being separated from the shock absorbing seat when being stressed.

The utility model discloses shock-proof wheel's beneficial effect is: through the cooperation of last seat of moving away to avoid possible earthquakes, lower seat of moving away to avoid possible earthquakes and the spring of moving away to avoid possible earthquakes for the shock-proof performance of wheel obtains improving, and these three still have limiting displacement simultaneously, have improved the stability and the practicality of wheel.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
