Description
Technical field
The invention belongs to wheelchair field, relate to the universal wheel that wheelchair is used, the adjustment height ten thousand of a kind of wheelchair
To wheel.
Background technology
At present, the wheelchair that people with disability is used, its universal wheel is fixed, it is impossible to adjusts its height, therefore can not meet
Requirement for disabled.
By retrieval, finding that patent document related with the present patent application is more, close has following two:
1, a kind of adjustable angle universal wheel (CN104553612A), it includes universal wheels, and it also includes: one supports and adjusts
Saving unit, it includes a support connector, and described support regulation unit is connected with described universal wheels, described universal in order to adjust
The left and right of wheels and front and rear angles；One accommodating unit, it is connected with a car body, regulates unit in order to accommodate described support, and makes
Described support connector and described accommodating unit produce one and relatively rotate.
2, a kind of universal wheel (CN104825286A), it is adaptable to the instruments such as wheelchair, universal wheel includes wheel body, described wheel
Main body is polygon, and the edge of polygonal wheel body arranges extends some legs laterally；Described several
Round platform tire it is respectively arranged on foot.
First of patent documentation disclosed above, is four angular adjustment realizing universal wheel itself, solves because of welding deviation
The universal wheel caused and ground off plumb factor；Second is then need not to pass through wheel body transverse shifting problem, therefore
All differ with goal of the invention and the technical scheme of the present patent application.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of flexible, location wheel reliably
The adjustment height universal wheel of chair.
The present invention solves technical problem and be the technical scheme is that
The adjustment height universal wheel of a kind of wheelchair, including a stay tube, installs set, crotch and castor, props up stay tube and installs set
Coaxially connected, the lower bottom of this installation set is fixedly mounted with crotch, and this crotch installs castor, it is characterised in that: described stay tube and installation set
Between a coaxially connected screw shaft, this screw shaft upper end is connected with stay tube, and lower end is mounted, thus with installation set by mounting head
Realize screw shaft coaxial rotating in installing set and a stay tube；Radial direction at a stay tube at screw shaft position is fixedly mounted with an installation
Seat, is co-axially mounted a bevel gear shaft in this mounting seat, the axle head of this bevel gear shaft is fixedly mounted with a bevel gear, and this bevel gear is installing set
Interior engagement with screw shaft is connected.
And, the bevel gear axle head outside mounting seat is radially fixedly mounted with a hand crank.
The present invention with good effect is a little:
This universal wheel is set with a screw shaft supporting inner coaxial tube, and this screw shaft one end is connected with stay tube, the other end and
The installation set mounting of castor, installs a hand bevel gear at a stay tube outer radial, the screw rod in this bevel gear elongate support pipe
Axle, is achieved in oscilaltion during screw shaft engagement bevel gear, thus drives castor lifting in a stay tube, and total sets
Meter science, is skillfully constructed, and overcomes the technical barrier that existing universal wheel exists, and market prospect is the most wide.
Accompanying drawing explanation
Fig. 1 is the structural front view of the present invention；
Fig. 2 is the axis cross-sectional view of Fig. 1.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, and following example are descriptive
, it not determinate, it is impossible to limit protection scope of the present invention with this.
The adjustment height universal wheel of a kind of wheelchair, including a stay tube 1, installs set 6, crotch 7 and castor 8, stay tube and peace
Encapsulation is coaxially connected, and the lower bottom of this installation set is fixedly mounted with crotch, and this crotch installs castor.
The innovative point of the present invention is:
Propping up stay tube and install a coaxially connected screw shaft 5 between set, this screw shaft upper end is connected with a stay tube, and lower end is passed through
Mounting head 10 mounts with installing set, is achieved in screw shaft coaxial rotating in installing set and a stay tube；At screw shaft position
The radial direction of stay tube be fixedly mounted with a mounting seat 2, be co-axially mounted a bevel gear shaft 3 in this mounting seat, the axle head of this bevel gear shaft is solid
Filling a bevel gear 9, this bevel gear is connected with screw shaft engagement in installing set.
For ease of the rotation of bevel gear shaft, the bevel gear axle head outside mounting seat is radially fixedly mounted with a hand crank 4.
The operation principle of the present invention is:
Hand bevel gear shaft, the screw shaft in bevel gear elongate support pipe, be achieved in screw shaft engagement bevel gear time on
Lower lifting, thus drive castor lifting in a stay tube.
Claims (2)
1. an adjustment height universal wheel for wheelchair, including stay tube, installs set, crotch and castor, a stay tube with install set with
Axle connection, the lower bottom of this installation set is fixedly mounted with crotch, and this crotch installs castor, it is characterised in that: described stay tube and installation set
Between a coaxially connected screw shaft, this screw shaft upper end is connected with stay tube, and lower end is mounted with installation set by mounting head, thus reality
Existing screw shaft coaxial rotating in installing set and a stay tube；Radial direction at a stay tube at screw shaft position is fixedly mounted with a mounting seat,
