Abstract

The invention discloses a medical caster which comprises a first wheel, a second wheel and a third wheel. A first bearing, a second bearing and a third bearing are inserted into the middle of the first wheel, the middle of the second wheel and the middle of the third wheel in a penetrating mode respectively, the two ends of the first bearing, the two ends of the second bearing and the two ends of the third bearing are all fixedly provided with triangular fixing frames and provided with first bearing seats, main shafts are inserted into the middles of the triangular fixing frames in a penetrating mode, the two ends of the main shafts are fixedly provided with protective shells, and the tops of the protective shells are provided with second bearing seats. According to the medical caster, the three wheels are fixed through the triangular fixing frames, the wheels can be replaced to cross the road surface when the caster encounters an obstacle, the damping effect of the caster is further improved by sleeving damping sleeves on the main shafts, the second bearing seats are arranged to be used as universal wheels, and therefore the caster is more flexible.

Description

A kind of medical castor

Technical field

The present invention relates to castor technical field, be specially a kind of medical castor.

Background technology

Castor is a kind of common mechanical Hardware fitting, usually the footing of furniture, go-cart, mechanical equipment, medical bed etc. is arranged on to facilitate the movement of object, when castor is used on medical bed and Medical trolley, when Medical trolley is executed the task out of doors, various road surface can be run into unavoidably, and aobvious no doubt important of the damping effect of castor, common castor is difficult to cross, once too jolt also can cause secondary injury to patient running into low-lying or protruding road surface.

Summary of the invention

For the technical matters of above-mentioned existence, the object of the invention is: the medical castor proposing a kind of High Performance use safety.

Technical solution of the present invention is achieved in that a kind of medical castor, comprises the first wheel, the second wheel and the 3rd wheel; The middle part of described first wheel, the second wheel and the 3rd wheel is interspersed with clutch shaft bearing, the second bearing and the 3rd bearing respectively, and the two ends of clutch shaft bearing, the second bearing and the 3rd bearing are all installed with three corner steady; The two ends of described clutch shaft bearing, the second bearing and the 3rd bearing are all provided with clutch shaft bearing seat; The middle part of described three corner steady is interspersed with main shaft, and main shaft extends to the outside of three corner steady; The outside face of described main shaft is socketed with shock-absorbing sleeve; The two ends of described main shaft are installed with screened housing, and the top of screened housing is provided with the second bearing seat.

Preferably, described first wheel, the second wheel and the 3rd wheel are equilateral triangle distribution.

Preferably, described three corner steady adopt stainless steel.

Preferably, the inside of described screened housing is added with stiffener skeleton.

Preferably, described shock-absorbing sleeve is rubber coating or silica gel sheath.

Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:

1, by three wheels are fixed together by three corner steady, can work as castor run into different road surfaces can more wheel change to spend road surface;

2, be socketed with shock-absorbing sleeve by the outside face at main shaft, further improve the damping effect of castor entirety;

3, by being provided with the second bearing seat at the top of screened housing, castor can be made to regard cardan wheel and to use, more flexibly.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solution of the present invention is described further:

Fig. 1 is the structural representation of medical castor of the present invention;

Fig. 2 is the left view of medical castor of the present invention.

In figure: 1, screened housing; 2, the first wheel; 3, the second wheel; 4, the 3rd wheel; 5, clutch shaft bearing; 6, the second bearing; 7, the 3rd bearing; 8, main shaft; 9, three corner steady; 10, shock-absorbing sleeve; 11, clutch shaft bearing seat; 12, the second bearing seat.。

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described.

Refer to Fig. 1-2, the invention provides a kind of technical scheme: a kind of medical castor, comprise the first wheel 2, second wheel 3 and the 3rd wheel 4, described first wheel 2, second wheel 3 and the distribution in equilateral triangle of the 3rd wheel 4, described first wheel 2, the middle part of the second wheel 3 and the 3rd wheel 4 is interspersed with clutch shaft bearing 5 respectively, second bearing 6 and the 3rd bearing 7, and clutch shaft bearing 5, the two ends of the second bearing 6 and the 3rd bearing 7 are all installed with three corner steady 9, described three corner steady 9 adopt stainless steel, by three wheels are fixed together by three corner steady 9, can work as castor run into different road surfaces can more wheel change to spend road surface, described clutch shaft bearing 5, the two ends of the second bearing 6 and the 3rd bearing 7 are all provided with clutch shaft bearing seat 12, the middle part of described three corner steady 9 is interspersed with main shaft 8, and main shaft 8 extends to the outside of three corner steady 9, the outside face of described main shaft 8 is socketed with shock-absorbing sleeve 10, described shock-absorbing sleeve 10 is rubber coating or silica gel sheath, by being socketed with shock-absorbing sleeve 10 at the outside face of main shaft 8, the damping effect of further raising castor entirety, the two ends of described main shaft 8 are installed with screened housing 1, and the top of screened housing 1 is provided with the second bearing seat 11, by being provided with the second bearing seat at the top of screened housing 1, 11 can make castor regard cardan wheel uses, more flexible, the inside of described screened housing 1 is added with stiffener skeleton.

The principle of work of this invention: normal be the second wheel 3 and the 3rd wheel 4 when travelling is drive wheel, when the second wheel 3 or the 3rd wheel 4 run into obstacle, first wheel 2 can rotate around main shaft 8 and make it land, and the outside face of main shaft 8 is provided with shock-absorbing sleeve 10 can play damping effect to castor, and be mutually used alternatingly by three wheels, also the wearing and tearing of same wheel can be reduced, can cross by pulsation-free when also can run into obstacle to castor, also be provided with the second bearing seat 12 simultaneously, when castor needs to turn to, the second bearing seat 12 pairs of castors can be had more rotate.

Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
