Abstract
The present invention relates to a wheelchair pedal driven to lift by a rack. A pedal tube is fixedly mounted on a frame of a wheelchair; a pedal is mounted on the lower end of the pedal tube; a telescopic tube is coaxially sleeved by the pedal tube; a rack is arranged on the upper part of the telescopic tube in the pedal tube; the pedal is fixedly mounted on the lower end of the telescopic tube; a mounting seat is fixedly arranged on the part, corresponding to the part with the rack of the telescopic tube, of the pedal tube; a straight gear is horizontally mounted in the mounting seat; and the straight gear is meshed with the rack arranged on the telescopic tube in the pedal tube, so that the telescopic tube lifts when the rack is meshed with the straight gear, and the pedal is driven to lift in the pedal tube. The entire structural design is scientific; the idea is ingenious; the technical problem of the existing pedal is overcome; and the market prospect is very broad.
Description
Technical field
The invention belongs to wheelchair field, relate to the improvement to Wheel chair pedal plate, the wheel of a kind of rack drives lifting
Chair pedal.
Background technology
Wheelchair is available to participate in the conventional medical rehabilitation instrument that patient or man at an advanced age are used, and is also the special of walking
With instrument, this kind of wheelchair is fitted with greatly pedal, and one facilitates the foot-operated use of above-mentioned crowd.Current pedal, mostly installs
In pedal tube bottom, pedal self can inwardly rotate, to reduce people's foot and the obstacle of leg.
By retrieval, finding that patent document related with the present patent application is more, close has following three:
1, a kind of wheel-chair pedal (CN202682221U), including pedal, also includes that lower limb tube, spring location fills
Putting, described pedal is arranged in lower limb tube, and wheelchair body is provided with spring-positioning device, and lower limb tube is provided with spacing hole,
Lower limb tube is sleeved on wheelchair body.2, a kind of Wheel chair pedal plate (CN203122809U), including pedal, arm, described pedal
Being connected by rotary apparatus with described arm, described rotary apparatus includes fixing seat, rotating seat, latch segment, described fixing seat, institute
State rotating seat, described latch segment three and side by side and connected the center of three in order by a bolt, in described rotating seat
Offering arc-shaped slot below the heart, described fixing seat, the central lower of described latch segment pass through another root bolt and described arcuate groove
Hole connects.
3, a kind of Wheel chair pedal plate mechanism (CN201312862), it includes the pedal that pedal tube and pedal tube lower end connect,
It is characterized in that, the described pedal tube other end is connected on the vehicle frame of described wheelchair by rotatable device, and described pedal can turn over
Turn and be connected to pedal tube one end.The present invention facilitate occupant have a meal near desk, the operation such as bookcase reading, decrease pedal
Occupy space.
Above-mentioned three patent documents, first is liftable pedal, and second is to increase the anglec of rotation, the 3rd
A piece is collapsible.Although above-mentioned three documents solve certain problem, but operation or even structure still have a unreasonable part, and with
The present patent application is different in technical scheme.
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 the wheelchair pedal of a kind of rack drives lifting
Plate, the lifting of this pedal is convenient, and processing ease is skillfully constructed.
The present invention solves technical problem and be the technical scheme is that
The Wheel chair pedal plate of a kind of rack drives lifting, the chair frame of described wheelchair is fixedly mounted with pedal tube, under this pedal tube
End installation foot pedal, it is characterised in that: described pedal realizes lifting by the lowering or hoisting gear being arranged on pedal tube, should
The structure of lowering or hoisting gear is: coaxial package one telescoping tube in pedal tube, and this telescoping tube top in pedal tube is shaped with tooth bar,
The lower end of telescoping tube is fixedly mounted with pedal；The pedal tube at telescoping tube made tooth bar position is fixedly mounted with a mounting seat, in this mounting seat
Being transversely mounted a spur gear, this spur gear engages the tooth bar that the telescoping tube in pedal tube is made.
And, the spur gear axle head outside mounting seat is fixedly mounted with a hand crank, and this hand crank rotates thus turn spur rotation
Turning, spur gear engagement drives the rack displacement that telescoping tube is made.
And, on the plate face of described pedal, longitudinally hinge fills a hinge, by this hinge, pedal is realized to both sides
Upset.
The present invention with good effect is a little:
This pedal is coaxial package one telescoping tube in pedal tube, and this telescoping tube top in pedal tube is shaped with tooth bar,
The lower end of telescoping tube is fixedly mounted with pedal；The pedal tube at telescoping tube made tooth bar position is fixedly mounted with a mounting seat, in this mounting seat
Being transversely mounted a spur gear, this spur gear engages the tooth bar that the telescoping tube in pedal tube is made, is achieved in rack shaft engagement straight
Oscilaltion during gear, thus drive pedal lifting in pedal tube.Total design science, is skillfully constructed, and overcomes
The technical barrier that existing pedal exists, market prospect is the most wide.
Accompanying drawing explanation
Fig. 1 is the structural front view of wheelchair of the present invention；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the A portion structure enlarged diagram of Fig. 1；
Fig. 4 is the cross-sectional schematic of Fig. 3.
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 Wheel chair pedal plate of a kind of rack drives lifting, the chair frame of described wheelchair 1 is fixedly mounted with pedal tube 2, this pedal tube
Lower end installation foot pedal 6, pedal realizes lifting by the lowering or hoisting gear 3 being arranged on pedal tube.
The structure of described lowering or hoisting gear is:
See Fig. 3,4, coaxial package one telescoping tube 4 in pedal tube, this telescoping tube top in pedal tube is shaped with tooth
Bar 9, the lower end of telescoping tube is fixedly mounted with pedal；The pedal tube at telescoping tube made tooth bar position is fixedly mounted with a mounting seat 7, this installation
Being transversely mounted a spur gear 10 in Zuo, this spur gear engages the tooth bar that the telescoping tube in pedal tube is made, is achieved in rack shaft
Oscilaltion during engagement spur gear, thus drive pedal lifting in pedal tube；Spur gear axle head outside mounting seat is solid
Filling a hand crank 8, this hand crank rotates thus turn spur and rotates, and spur gear engagement drives the tooth bar position that telescoping tube is made
Move, and then telescoping tube oscilaltion, drive the lifting of pedal.
On the plate face of described pedal, longitudinally hinge fills a hinge 5, makes pedal realize turning over to both sides by this hinge
Turn.
