Wheelchair bearing protective cover

Abstract

The invention discloses a wheelchair bearing protective cover which adopts a structure that a protective cover shell is sectionally opened outwards and a bearing is hidden inwards, and after the wheelchair bearing protective cover is additionally arranged, in the rotating process of front wheels of a wheelchair, the situation that the rotating speed is affected due to the fact that hair is rolled up on the front wheels of the wheelchair and winds the bearing can be effectively prevented; and the segmented cleaning opening can be used for rapidly and conveniently cleaning hair winding, the bearing is hidden on the inner side of the bearing protection cover while sliding rotation of the bearing is not affected, and the bearing protection cover is used for protecting the center shaft bearing and preventing rainwater and dust from easily permeating into the bearing to cause corrosion. The device is novel in structural design, is researched and created from the fine feeling of using a wheelchair, and has an obvious bearing protection effect; the device is high in practicability, can help to solve the problem of daily maintenance of a wheelchair user on the bearing, remarkably prolongs the service life of the wheelchair bearing, can be widely applied to the field of wheelchair use of limb handicapped groups, improves the wheelchair use function, and increases welfare for the limb handicapped groups.

Description

TECHNICAL FIELD

[0001] The present application is widely used in the wheelchair use field of the limb disabled group;The structural design of the present application is novel, which is developed and created from the subtle feeling of using a wheelchair, and the protection effect of the bearing is obvious;The present application has strong practicability and can help solve the daily maintenance problem of the wheelchair user for the bearing, significantly improve the service life of the wheelchair bearing, and improve the performance of the wheelchair bearing. BACKGROUND

[0002] With the increase of the population aging population and the limb disabled group using wheelchairs, as an important home life travel tool, wheelchair plays an important role in bringing convenience to the disabled group, while some headaches appear in the daily use of wheelchair, because the front wheel of the wheelchair is close to the ground, when the front wheel rotates, the tire will stick to the hair and sundries and wrap around the front fork shaft close to the bearing position, which is difficult to clean after years of accumulation, and the mixture of dust and rainwater penetrates into the bearing, causing the bearing to rust and damage, which seriously affects the rotation speed of the front wheel bearing and the service life of the bearing. As the wheelchair user deeply feels the trouble, the wheelchair manufacturing enterprises usually do not pay attention to the subtle problems in the use process of the wheelchair, but the replacement of the bearing is a very difficult problem, which needs professional maintenance personnel to help complete the replacement work with professional tools;The present application is developed and created from the subtle feeling of using a wheelchair, and the installation of the wheelchair bearing protection cover can effectively solve the maintenance problem of the wheelchair bearing in use, reduce the maintenance cost, improve the service life of the wheelchair bearing, and hope that the wheelchair manufacturing enterprises pay attention to and learn from it, improve the performance of the wheelchair bearing, add happiness to the limb disabled group, and promote the development of the wheelchair industry. SUMMARY

[0003] The purpose of the present application is to provide a wheelchair bearing protection cover with compact structure and convenient use.

[0004] The technical scheme adopted by the present application is: the wheelchair bearing protection cover comprises a wheelchair bearing protection cover;Outwardly turned anti-winding wing;Segmented cleaning opening;Hooked winding induction area.

[0005] The wheelchair bearing protection cover hides the bearing position inside the bearing protection cover, which is used for hiding and protecting the shaft bearing.

[0006] The outwardly turned anti-winding wing is divided into three equal parts outside the bearing protection cover shell, which is used for preventing hair from winding around the shaft.

[0007] The segmented cleaning opening is divided into three equal parts outside the bearing protection cover shell, which is used for easily taking out the winding object.

[0008] The hooked winding induction area is divided into three equal parts outside the bearing protection cover shell, which is used for concentrating the winding object in the induction area. BRIEF DESCRIPTION OF DRAWINGS

[0009] The application is further described below in conjunction with specific embodiments in FIG. 1, FIG. 2, FIG. 3.

[0010] In FIG. 1: 1, wheelchair bearing protection cover 2, segmented cleaning opening 3, inverted hook winding induction area 4, everted anti-winding wing 5, everted anti-winding wing 6, segmented cleaning opening 7, middle shaft hole 8, everted anti-winding wing 9, segmented cleaning opening

[0011] FIG. 1 is a structural schematic diagram of the application.

[0012] FIG. 2 is a cross-sectional view and specific embodiment cross-sectional view of the application.

[0013] FIG. 3 is a specific embodiment assembly diagram of the application with a front fork. DETAILED DESCRIPTION

[0014] As shown in FIG. 1: a wheelchair bearing protection cover, the 2, 6, 9 segmented cleaning openings 3 inverted hook winding induction area 4, 5, 8 everted anti-winding wing is divided into three sections on the outside of the 1 wheelchair bearing protection cover shell, the 1 wheelchair bearing protection cover is passed through the 7 middle shaft hole, the middle shaft bearing is hidden in the 1 wheelchair bearing protection cover, the locking side fixed bolt, rotating the wheelchair front wheel test rotation smooth 1 wheelchair bearing protection cover installation is completed.

[0015] After installing the 1 wheelchair bearing protection cover, the hair and debris stuck in the tire during daily use will be brought into the 3 inverted hook winding induction area along the 1 wheelchair bearing protection cover shell, and the 4, 5, 8 everted anti-winding wing will prevent the hair from being wound into the middle shaft. If cleaning is required, the 2, 6, 9 segmented cleaning openings can be easily removed.

[0016] The specific installation can be executed by referring to FIG. 2, which is a cross-sectional view and specific embodiment cross-sectional view of the application, and FIG. 3, which is a specific embodiment assembly diagram of the application with a front fork.

[0017] The wheelchair bearing protection cover structure is scientific and novel in design, practical and convenient in function, and beautiful in modeling, and can be widely used for wheelchair bearing protection; the wheelchair bearing protection cover is developed and created from the subtle feeling of using a wheelchair, and can effectively solve the maintenance problem of the wheelchair bearing in use, reduce the maintenance and use cost, easily remove the winding, prevent the mixture of dust and rainwater from penetrating to cause bearing rust, make the wheelchair bearing rotate like silk after a long time, ensure the rotation speed of the wheelchair bearing and improve the service life of the bearing. It is believed that the invention of the product can be rapidly popularized and generalized, and wheelchair production enterprises can refer to it for reference to improve the performance of wheelchair bearings and add well-being to the physically disabled group, and promote the development of the wheelchair industry.
