Abstract

The utility model relates to a wheel chair allowing the seat angle to be adjusted. The wheel chair comprises large wheels, a horizontal bracket, a seat, a vertical bracket and a guide wheel; the large wheels are mounted at the two ends of a wheel shaft; one end of the horizontal bracket is mounted on the wheel shaft of the large wheel, and the other end is sleeved on the vertical bracket, wherein solenoidal valves are arranged on two sides of the other end; the seat is mounted on the horizontal bracket, and a pedal, an armrest and a backrest are arranged on the seat; the vertical bracket is mounted on the guide wheel, and a pushing handle is arranged at the top end of the vertical bracket; and the guide wheel is mounted at the lower end of the vertical bracket. The wheel chair has a simple structure, is comfortable and reliable, can allow the seat angle to be adjusted at will when going up or down a slope, can effectively reduce potential safety hazard, is applicable to people needing to use wheel chairs, and has a broad market prospect.

Description

Can regulate the wheelchair of chair angle

Technical field

This utility model relates to a kind of wheelchair, the especially a kind of wheelchair that can regulate chair angle.

Background technology

Wheelchair is the important tool of rehabilitation, and it is not only the walking-replacing tool of limbs the disabled, the more important thing is to make them carry out physical exercise and to participate in social activity by means of wheelchair.Wheelchair kind in the market is a lot, can be divided into aluminium alloy, lightweight material and steel by material, as can being divided into common wheelchair and specifical wheelchair by type.Specifical wheelchair can be divided into again: the outdoor activity wheelchair is serial, the electronics wheelchair is serial, seat side wheel chair is serial, help the wheelchair series etc. of stopping.

Traditional wheelchair seat is fixed on the lateral frame, and angle can't be regulated, during through upward slope or descending highway section; Because horizontal, vertical support relative position is fixed; Seat is with domatic parallel, like this health can be backward or turn forward, bring to health also to have potential safety hazard uncomfortable the time.

The utility model content

To the deficiency that the traditional push chairs chair angle can't be regulated, the purpose of this utility model provides a kind of wheelchair that can regulate chair angle, and it can be regulated the angle of seat, going up a slope or letting the health held stationary during descending, efficiently solves the problems referred to above.

For the technical scheme that purpose adopted that realizes this utility model is: a kind of wheelchair that can regulate chair angle is characterized in that: it is made up of bull wheel, lateral frame, seat, perpendicular support and directive wheel; Described bull wheel is installed in the two ends of wheel shaft; Described lateral frame one end is installed on the wheel shaft of bull wheel, and the other end is enclosed within on the perpendicular support, and its both sides are provided with screw valve; Described chair mounted which is provided with pedal, handrail and backrest on lateral frame; Described perpendicular support is installed on the directive wheel, and its top is provided with and pushes away handle; Described directive wheel is installed in the lower end of perpendicular support.

The beneficial effect of this utility model is: simple in structure, comfortable reliable, can be when last downslope the regulated at will chair angle, effectively reduce potential safety hazard, be applicable to the crowd who needs the use wheelchair, market prospect is wide.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment this utility model is described further.

1-pedal, 2-bull wheel, 3-wheel shaft, 4-seat, 5-handrail, 6-backrest, 7-push away handle, the perpendicular support of 8-, 9-draw-in groove, 10-lateral frame, 11-screw valve, 12-directive wheel, 13-slope, 14-screw thread among the figure.

The specific embodiment

In Fig. 1, Fig. 2, first embodiment shown in Figure 3, a kind of wheelchair that can regulate chair angle is characterized in that: it is made up of bull wheel, lateral frame, seat, perpendicular support and directive wheel; Described bull wheel is installed in the two ends of wheel shaft; Described lateral frame one end is installed on the wheel shaft of bull wheel, and the other end is enclosed within on the perpendicular support, and its both sides are provided with screw valve; Described chair mounted which is provided with pedal, handrail and backrest on lateral frame; Described perpendicular support is installed on the directive wheel, and its top is provided with and pushes away handle; Described directive wheel is installed in the lower end of perpendicular support.

In Fig. 1, Fig. 2, second embodiment shown in Figure 3, perpendicular support is provided with draw-in groove, and the draw-in groove inwall is provided with female thread; Screw valve is provided with external screw thread, can cooperate with draw-in groove, with the fixing position of lateral frame.

When using this utility model, before wheelchair was through the slope, the screw valve that will be positioned on the lateral frame was unscrewed, and according to the angle of slope gradient adjustment lateral frame, seat also changes the angle with the slope thereupon; When angle is suitable, make screw valve aim at corresponding draw-in groove on the perpendicular support, tighten screw valve, at this moment, move ahead on the slope just can not occur because of seat tilt to cause uncomfortable with have potential safety hazard; When wheelchair is got back to level road, readjust lateral frame to level angle, make seat remain level.Simple to operate, safe and practical.
