Background technology
Existing cart because of it conveniently, economical and environmentally friendly, is used, but the traffic of its manufacture by more and more people
Accident quantity is also very big, in addition to because road conditions, congestion, not observing traffic rules and regulations and technical problem of riding
Outside, the technological deficiency of vehicle brake itself is also major reason.Existing vehicle stop all using two parking brakes on headstock transverse tube come
Manipulate forward and backward brake respectively, somebody is unreal when cycling to hold handlebar, and Toe Transplantation for Segmental Finger rides over parking brake upper, both dangerous, also not just
Just the operation of speed control crank, somebody hold handlebar in fact, and an emergency situation is encountered can have little time handgrip brake lever, and winter wears gloves, summer
Hand is perspired, these problems just become apparent from.The use sequencing problem of also forward and backward parking brake, although producer is in vehicle operation instructions
On all emphasize it is inaccurate individually or first using preceding brake, when otherwise speed is fast can whipping or before turn over and cause danger, this Bi Jing is that vehicle stops this
The technological deficiency of body only points out it is inadequate on specification.
Tricycle, refer here to headstock transverse tube turn to, the tricycle of hand-braking, it is indicated above the problem of, greatly
Partly it also has.
Invention content
The purpose of the present invention, aiming at problem above, can be trusted when a kind of cycling is provided it is real hold handlebar, during brake before,
Trailing wheel is that autosynchronous synchronizing trolley is stopped.
The present invention synchronizing trolley stop, mainly by frame cross (1), rear profile tube (2), u-bracket (3), damping spring (4),
Damping spring stent (5), braking rope pulling plate (6) and braking rope pulling plate bracket (7) are formed, wherein the rear end of frame cross (1)
U-bracket (3) is welded with, the mounting hole (3-1) for there are two rear profile tubes (2) thereon, the side of rear profile tube (2) is welded with damping spring branch
Frame (5) is welded with axle sleeve (5-1) and is formed with the hole (5-2) of installation damping spring (4) thereon, and rear profile tube (2) passes through axle sleeve (5-1)
Hinged with axis and u-bracket (3) with hole (3-1), damping spring (4) upper end bolt is through hole (5-2) and damping spring stent (5)
Connection, lower end are fixed in Rear frame (9), the top of rear profile tube (2), and U-shaped branch is abutted against under the promotion of damping spring (4) elastic force
The upper edge of frame (3), in stable state, brake rope support (7) is welded on vehicle frame, braking rope pulling plate (6) and brake rope support
(7) hinged, the upper end is in contact by idler wheel (6-1) with rear profile tube (2), and two braking ropes (8) are each passed through braking rope pulling plate
(6) hole (6-2) in forward and backward two torque arm in lower section connects with forward and backward brake, and as cyclist, Yi leaves body backward, passes through saddle
(10), saddle pipe (11) drives rear profile tube (2) to be rotated clockwise with hole (3-1) for the garden heart, and passes through rear profile tube (2) lower end and push brake
Vehicle rope pulling plate (6) counterclockwise, so as to pull the forward and backward brake of forward and backward two braking ropes (8) synchronous drive being through thereon,
Brake vehicle.
Synchronizing trolley using the present invention is stopped, and advantage is:
1. because the braking rope (8) of forward and backward lock pulls simultaneously, the braking of forward and backward lock is synchronous.
2. Yi brakes after present invention body, meet in case of emergency, the instinct that body can retreat is anti-
Should, it will not be sluggish, it will not be at a loss, so acting naturally, the reaction time is short.
3. brake without hand grip, but use the strength of trunk, so brake it is light and handy, laborsaving, brake force is big, when long
Between brake, if lower long slope does not also tire out, fitting very much various carts and tricycle, particularly Moped Scooter and women and children makes
With.
4. both hands can relievedly hold handlebar in fact, make to drive more comfortable and safe.
5. there is no parking brake and braking rope on handlebar, make vehicle beautiful and clean, folding convenient.
Specific embodiment
Embodiment of the present invention is as follows, and u-bracket 3 is first welded in frame cross 1, and rear profile tube 2 is mounted in u-bracket
(3) after on, damping spring 4 is refilled, at this moment the top of rear profile tube 2 should abut against the rear edge suitable for reading of u-bracket 3, braking rope pulling plate 6
Idler wheel 6-1 should be in contact with rear profile tube 2, pulling rear profile tube 2 rotates clockwise it, should be able to push 6 inverse time of braking rope pulling plate
Needle rotates, and two braking ropes 8 being through in the 6-2 of hole is pulled to brake forward and backward brake.The stability of rear profile tube 2, can be by subtracting
4 elastic force of spring is shaken to adjust, and can also can also pass through increasing by the way that the mounting hole 5-2 of 4 upper end of damping spring is selected to adjust
Subtract the distance of axle sleeve 5-1 and rear profile tube 2 to adjust, it is big apart from big stability, it is small apart from small stability, according to the above, just
The synchronizing trolley that the present invention can be formed is stopped.
