Abstract
The utility model relates to a wheel type walking aid combined with a drum brake assembly, which comprises a walking aid frame body, rolling wheels and a braking handle. The utility model is characterized in that the drum brake assembly arranged on wheel hubs of the rolling wheels is installed, and the braking handle is connected with the drum brake assembly through connecting pieces. The utility model has the advantages that drum braking operation is used, friction pieces are arranged in wheel rings. The reliability is enhanced, and the structure is simple. Thus, the operating safety of the wheel type walking aid can be enhanced.
Description
Affiliated technical field
This utility model relates to a kind of walking aid, especially in conjunction with the wheeled walker of drum brakes.
Background technology
At present, extensive use two-wheeled, three-wheel or four-wheel walking aid all are provided with brake gear, and its brake modes mainly is to utilize braking clamp clamping wheel frame, produces frictional force and brakes; Or utilize brake pad and tire friction to brake.The brake instability of this class formation for example, after wheel is stained with water, can form moisture film, and the coefficient of friction of wheel is significantly reduced, and braking quality is descended, and causes danger.
Summary of the invention
In order to overcome the deficiency of existing wheeled walker, this utility model provides a kind of wheeled walker in conjunction with drum brakes, and this walking aid is operation easily not only, and brake is reliable.
The technical scheme that its technical problem that solves this utility model adopts is: in conjunction with the wheeled walker of drum brakes, comprise the walking aid support body, roller, brake handle, it is characterized in that: be provided with the drum brakes assembly on the wheel hub that is installed in roller, brake is linking to each other with the drum brakes assembly by connector.
Described connector is a steel wire rope.
Described drum brakes assembly comprises wheel rim friction plate, brake strip, banking pin, alignment pin, dish seat, brake arm and haulage gear, the wheel rim friction plate is installed in wheel hub, banking pin, alignment pin are installed on the dish seat, brake arm one end connects with haulage gear, the other end connects with banking pin, brake strip is provided with and banking pin, mounting structure that alignment pin is corresponding, and is installed on the dish seat.
Described haulage gear comprises traction piece, locking nut and balance pipe, and balance pipe is installed on the dish seat, and traction piece passes balance pipe and utilizes locking nut to be fixed on the brake arm.
Described brake strip is a symmetrical structure.
Also be provided with cushion block, the through hole that described cushion block is provided with and banking pin, alignment pin are suitable and be arranged on brake strip and the dish seat between.
The beneficial effects of the utility model are, adopt drum brakes, and friction member is installed in the inside of wheel rim, improve reliability, and simple in structure; This has all improved the safety in utilization of wheeled walker.
