Problems solved by technology
[0003] But existing tricycle axle is fixed with brake wheel and dead wheel, brakes wheel by brake band, thereby makes tricycle axle one end dead wheel not turn, because brake band is housed with fixing screw and brake wheel surface is smooth, will cause braking effect It is very poor, and the brake device of the existing tricycle is a single-wheel brake, and it is easy to turn the body when the brake is sudden, or cause an accident

Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] see Figure 1-2 As shown, a two-wheel brake device includes a ring bar 1 and a first brake disc 2 and a second brake disc 3 that cooperate with each other. One end of the ring bar 1 is provided with a number of pin holes 4, and the middle part of the pin hole 4 is provided with a fixing groove 5. One end of the ring bar 1 is fixedly connected to the external tricycle pull rod, and the other end of the ring bar 1 is connected to the frame of the tricycle...

The invention discloses a two-wheeled braking device and a rickshaw. The two-wheeled braking device comprises an annular strip, a first braking disc, a second braking disc, a pin hole, a fixing groove, a first screw hole, a second screw hole, a fixing hole, a clamping groove, a brake band, a spring piece, screws and nuts. In the two-wheeled braking device, the first braking disc and a movable hubare combined together to run, the second braking disc and a fixed wheel are combined together to run, a rickshaw pull rod can be pulled through the annular strip during braking, the first braking discand the second braking disc are clamped by utilizing the trapezoid annular strip, simultaneous braking of two wheels can be achieved, a braking effect is effectively improved, the shortcoming that only one wheel of an original rickshaw can be braked is overcome, the braking effect is effectively improved, the personable safety of a rider is ensured, the annular strip and the trapezoid brake bandare fixed by the arranged spring piece, the annular strip and the trapezoid brake band are firmer to fix, and mounting and dismounting of the device are facilitated.
Description
technical field [0001] The invention relates to a brake device, in particular to a two-wheel brake device of a tricycle, and belongs to the technical field of tricycle accessories application. Background technique [0002] A tricycle is a bicycle with three wheels, equipped with a compartment or a flat panel, and is used for carrying people or loading goods. Tricycle is divided into front and back two parts, and front part has a wheel that can steer, and handlebar, bicycle bell, brake, pedal and vehicle seat drive the wheel rotation of rear part with chain. The rear part of the tricycle is mainly a carriage, which is a wooden semicircle, and two people can ride side by side. A foldable rainproof canopy is installed on the carriage, and springs and two wheels are housed below. [0003] But existing tricycle axle is fixed with brake wheel and dead wheel, brakes wheel by brake band, thereby makes tricycle axle one end dead wheel not turn, because brake band is housed with fix...
