Abstract

The utility model discloses a folding bicycle shock-reduction device whose bicycle frame is joggled with a rear fork. The rear fork is provided with an eject rod which can fasten the bicycle frame. The front end of the eject rod is ball-shaped raised head and the corresponding site of the bicycle frame is provided with a thick rubber bushing. The raised head may be inserted into the hole of the thick rubber bushing. When the bicycle is unfolding, the ball-shaped raised head on the front end of the rear fork eject rod is inserting into the thick rubber bushing on the bicycle frame. When the bicycle is running on the ragged road, the thick rubber bushing will adjust to it through proper elastic deformation; in addition, the friction between the raised head and the thick rubber bushing is large, under the function of friction, the raised head and the bushing will not come away and collide with each other so occasionally, therefore, the noise and vibration become even smaller and the riding turns out to much safe and comfortable.

Description

A kind of shock absorbing apparatus of folding bicycle

Technical field

This practical shock absorbing apparatus that newly relates to a kind of folding bicycle.

Technical background

Existing a kind of folding bicycle, as Fig. 1, its back vent 1 is hinged with vehicle frame 6, and when folding, back vent can be around hinge convolution forward, and during expansion, back vent 1 supports with vehicle frame by push rod 2 mutually at the arrow A place, and this kind folding bicycle is also referred to as volume type car.Existing volume type car, its push rod 2 and vehicle frame 6 are only by the contact surface support that offsets, as Fig. 2, when car is ridden on smooth surface, under the effect of people's gravity, it is good to guarantee that push rod and vehicle frame support, when so riding on rugged road surface, owing to jolt, push rod and vehicle frame break away from and collision easily, its vibration and noise are bigger, safety and comfort that influence is ridden.

The utility model content

It is more reliable that the purpose of this utility model is to provide a kind of back vent and vehicle frame to support, and during Uneven road, vibration and noise are less, and the folding bicycle shock absorbing apparatus of riding comparatively comfortable.

Folding bicycle shock absorbing apparatus of the present utility model, its vehicle frame and back vent are hinged, and the push rod that can push against vehicle frame is housed on the back vent, and the front end of its push rod is a plush copper spherical in shape, and the corresponding position is fixed with thick plastic casing-pipe on the vehicle frame, and plush copper can be inserted in the hole of thick plastic casing-pipe.

Folding bicycle shock absorbing apparatus of the present utility model, when car exhibition is opened, the spherical plush copper of back vent push rod front end inserts in the thick plastic casing-pipe on the vehicle frame, ride when jolting in the road surface of injustice when vehicle, its thick plastic casing-pipe can adapt to jolting of road by suitable elastic deformation, and plush copper is with afterwards the friction force between plastic casing-pipe is bigger simultaneously, under the friction force effect, its plush copper and sleeve pipe can be not regular disengagement and collision, thereby noise and vibration are littler, it is safer, comfortable to ride.

Description of drawings

Fig. 1 is a kind of structural representation of rolling up the type car;

Fig. 2 is existing volume type car extension bar and push rod connection structure scheme drawing;

Fig. 3 is the extension bar of volume type car of the present utility model and the connection structure scheme drawing of push rod.

The specific embodiment

As Fig. 3, a kind of folding bicycle shock absorbing apparatus, its vehicle frame 6 is hinged with back vent 1, the push rod 2 that can push against vehicle frame 6 is arranged on the back vent 1, the front end of push rod 2 has plush copper spherical in shape 4, and the corresponding position is fixed with thick plastic casing-pipe 3 on the vehicle frame 6, and plush copper 4 can be inserted in the hole 5 of thick plastic casing-pipe 3.

In order to strengthen the friction force between plush copper 4 and the thick plastic casing-pipe 3, make to be connected closelyr between plush copper 4 and the sleeve pipe 3, the diameter of the plush copper 4 of push rod 2 front ends can be slightly larger than the aperture of thick plastic casing-pipe 3.

Claims

1, a kind of shock absorbing apparatus of folding bicycle, cycle frame (6) is hinged with back vent (1), the push rod (2) that can push against vehicle frame is housed on the back vent (1), it is characterized in that: the front end of push rod (2) has plush copper spherical in shape (4), the fixing thick plastic casing-pipe (3) in corresponding position on the vehicle frame, plush copper (4) can be inserted in the hole (5) of thick plastic casing-pipe (3).

2, folding bicycle shock absorbing apparatus according to claim 1 is characterized in that: the slightly larger in diameter of described plush copper (4) is in the aperture of thick plastic casing-pipe (3).
