Coupled with the ageing of the population, the number of wheelchair users is increasing. It is very difficult to use a wheelchair, especially for the first-time users and the old and weak people living in the mountains: when the two push-type wheelchair users are on the slope of the τ, if they are: self-help or help, they will quickly fall back or rush. 'The situation is very dangerous. To solve the problem; == tender, tearing down to rest, break the number of people using wheelchairs in the year = more, so there are many new products, such as anti-wheel, bicycle brakes and oxygen transfer. =: Single::=Time---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Backward, prevent the wheelchair from slipping or rushing to the second, the month. Only to the front, not the device (two-knuckle type lever installed two users add a hand next to the tire is not afraid of slipping, and when pressing down the slope, when you encounter fatigue, you are not afraid of diving. Better overcome Now M433859 has the technical shortcomings. In order to achieve the above purpose, the author proposes: the other end of the connecting rod and the second connecting rod and the fourth joint, the first: the social _ 2 four miscellaneous materials - the end _ on Brake board brother - the private other end is pivotally connected to the lower brake plate, the job is on the top of the board, the other part of the board is ^;=: the brake wheel is mounted on the top, and the end of the lower brake board is pivotally connected to the shaft. = Set 2: Plate: - End mounted with board: ;:: Degree _ porous two == _ brother two pumping the lower brake plate below the brake plate and can be produced ==: contact · turn 'upper brake wheel and parking The wheel respectively has a brake pad and the fine contact contact point, a pivotal point of the fixed angle of the porous fixing plate, and a line with the upper brake wheel 2; the lower brake plate and the third The connecting rod: =: boring - point, and the parking groove, the fact that the cash wheel and the standing wheel table (four) are provided with a shaft groove or a mesh shape on the porous fixing plate 4 M433859 wherein the adjustable angle fixing plate has a fox-shaped through groove, wherein the one-way bearing comprises a ratchet wheel, wherein the brake wheel is an eccentric wheel, wherein the brake rod end is connected with a handle. With the domain of the above components, the creation does have an == and the creation has a simple structure, low cost, and money: = [Embodiment], the structure and characteristics of the structure are as shown in the figure, this The safety device 5 belongs to one of the wheels, and the tire is fixed by the adjustable angle fixing plate 61 or the perforated fixing plate 57. The tire of the traveling wheel 3 of the straight object 1 acts as a brake, parking: the three-link 54 of the board, parking The wheel 55, the τ brake plate 56, the porous=5=angle fixing plate 61, the upper brake wheel 58 (which is an eccentric wheel), and the first:=Τ link 60. Among them: the first link 52, connected to The second end is pivotally connected to the upper brake pad 59 at the other end of the fourth link 60. The first end/end is pivotally connected to the lower brake plate 56, and the upper brake plate 59 is 59. 5 simple fixing plate 61 or porous fixing plate 57, upper brake plate = 3;: mounted shaft (not shown), the axis on the Ancai The end of the wheel 4 plate 56 is pivotally connected to the adjustable angle fixing plate 61 or the porous fixing plate 5 M433859 57. The lower brake plate 56 is a one-way secret bearing (_ bicycle 2 is loaded (not shown), and the shaft is pushed Above the upper brake plate 59 - on the set of the standing wheel 55, the fourth link 60 is fixed (four) of the pivoting 'and: the angle adjustment plate 61 or the porous joint is the center of rotation, the loading of the second and second extension of the walking wheel 3 tire The mad soap wheel 55 acts on the wheelchair 〗 〖In the upper slope = double elbow (four) tree _4 === slip effect, when the lower slope is due to the standing wheel and two = 2 down when going up and down the slope can be used to double elbow The formula product = position. To prepare, use the off-axis brake wheel to press the tire, because the axis is biased to the side and the wheel and the brake wheel can be interchanged. Sex, this creation has its excellent progress in the same kind of products. Practical ==:: Shen: First, 'is a heart-only', the above is only the best practice of this creation, so the application This creation and application for the equivalent structural changes of the special fiber county should be included in the scope of this creation patent.
