Abstract
The utility model discloses a slide bushing type brake device for a truckle of a wheelchair. The slide bushing type brake device for the truckle of the wheelchair comprises a pipe leg mounted on a wheelchair frame and the truckle mounted on the pipe leg. A slide bushing is mounted on the pipe leg in a sleeved mode and connected with the pipe leg in a longitudinal sliding mode. The side, next to the truckle, of the slide bushing is provided with a brake arm in a transverse extension mode, and a brake cable is mounted on the brake arm and can drag the slide bushing to slide toward or away from the wheel surface of the truckle. According to the slide bushing type brake device, the slide bushing is mounted on the pipe leg in a sliding and sleeved mode, the brake arm and the slide bushing are integrally formed, force fed back from a brake all acts on the pipe leg, and therefore the slide bushing type brake device can bear large braking force and has a good braking effect.
Description
Technical field
This utility model relates to the wheelchair technical field, relates in particular to the brake gear of castor of wheel chair.
Background technology
Walking-aided wheelchair is for handicapped personage provides auxiliary walking and wheelchair function, and auxiliary user is stood and gone out to walk, shopping, and the seat that allows user have a rest is provided, and also can be sitting in simultaneously to allow other people promote on the wheelchair.The brake gear of traditional push chairs castor mostly is to adopt oscillating rod type, and fork is installed on the pin by a fulcrum, and the swinging end of fork is equipped with brake glue, fork is connected with brake cable, drawing fork by brake cable and swinging, brake glue is pressed on the wheel face of castor, castor is being stopped extremely.Because this oscillating rod type brake structure is thiner, braking strength is not enough, causes braking effect not ideal enough, even the excessive brake gear damage phenomenon that causes of braking strength can occur.Therefore, be necessary existing brake gear is made improvement, to strengthen its structural strength, provide enough braking strengths.
The utility model content
The technical problems to be solved in the utility model provides the brake gear of the castor of wheel chair that a kind of structural strength is high, braking effect is good.
For solving the problems of the technologies described above the technical scheme that adopts: a kind of sleeve type brake gear of castor of wheel chair, include the pin that is installed in wheelchair frame and be installed in castor on the pin, it is characterized in that: be set with the sliding sleeve that is connected with its longitudinal sliding motion on the described pin, that side horizontal expansion one brake arm of sliding sleeve next-door neighbour castor is equipped with on the brake arm and can draws that sliding sleeve slides to or the brake cable of the castor wheel face that slips away.
The beneficial effect that adopts this utility model to bring: because this utility model adopts the sleeve type brake gear, sliding sleeve is that slip cap is contained on the pin, brake arm and sliding sleeve are one-body molded, the dynamics that brake feeds back all acts on the pin, as seen this utility model can bear larger braking strength, and braking effect is good.
Description of drawings
Fig. 1 is the structural representation of the sleeve type brake gear of this utility model castor of wheel chair.
The specific embodiment
As shown in Figure 1, a kind of sleeve type brake gear of castor of wheel chair, include the pin one that is installed in wheelchair frame and be installed in castor 2 on the pin one, be set with the sliding sleeve 3 that is connected with its longitudinal sliding motion on the described pin one, that side horizontal expansion one brake arm 4 of sliding sleeve 3 next-door neighbour's castors 2, be equipped with on the brake arm 4 and can draw that sliding sleeve 3 slides to or the brake cable of castor 2 wheel faces that slip away (common parts indicate among the figure).
During brake, brake cable tension sliding sleeve 3, sliding sleeve 3 slides towards castor 2, and brake arm 4 is pressed on the castor wheel face, and castor 2 can't be rotated, and castor 2 is stopped extremely.
Claims (1)
1. the sleeve type brake gear of a castor of wheel chair, include the pin that is installed in wheelchair frame and be installed in castor on the pin, it is characterized in that: be set with the sliding sleeve that is connected with its longitudinal sliding motion on the described pin, that side horizontal expansion one brake arm of sliding sleeve next-door neighbour castor is equipped with on the brake arm and can draws that sliding sleeve slides to or the brake cable of the castor wheel face that slips away.
