Abstract

The utility model relates to a hydraulic shock absorber for a bicycle, which comprises a hydraulic cylinder body. A piston composed of a piston rod and a piston ring for connecting the piston rod is arranged in the hydraulic cylinder body. The piston rod extends outwards, a spring seat is arranged at the rear end of the piston rod, and threads are arranged on the outer surface of the hydraulic cylinder body and provided with an adjusting bolt. A spring is sleeved on the hydraulic cylinder body, one end of the spring is connected with the spring seat, and the other end of the spring is connected with the adjusting bolt. The hydraulic cylinder body is connected with an oil storage barrel which is connected with an oil pressure adjuster. The hydraulic shock absorber for the bicycle utilizes a hydraulic structure to absorb the shock. Even though a rider has large body weight or the shock is large, the hydraulic shock absorber for the bicycle has good shock absorbing effect.

Description

A kind of hydraulic damper that is used for bicycle
(1) technical field
The utility model relates to a kind of hydraulic damper that is used on bicycle, the electric bicycle.
(2) background technique
Bicycle in the process of moving, owing to Uneven road etc. reason, have certain vibrations; Vibration damper is a kind of device that slows down bicycle, electric bicycle impact; Its major function has two aspects: the one, and can be as far as possible the impact on ground be alleviated to minimum level, thereby increase substantially comfort level by bike, the 2nd, can make tire be adjacent to ground as far as possible; It is had more grab the ground ability, and then improve the rideability of bicycle.Damping device of the prior art is fairly simple, just relies on damping spring to come support frame, if meet the tall and big knight of build, does not then have damping effect.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing technology, the utility model provides a kind of damping effect hydraulic damper preferably.
The technological scheme that the utility model solves its technical problem is:
A kind of hydraulic damper that is used for bicycle comprises hydraulic cylinder, is provided with piston in the described hydraulic cylinder; Described piston comprises piston rod and the piston ring that is connected piston rod, and described piston rod stretches out, and the rear end of piston rod is provided with a spring seat; The outer surface of described hydraulic cylinder is provided with screw thread, and a regulation cock is set on the screw thread, an also sheathed spring on the described hydraulic cylinder; One end of described spring connects spring seat; The other end connects regulation cock, and described hydraulic cylinder connects an oil storage cylinder, and described oil storage cylinder connects an oil pressure regulator.
As improvement, be provided with oil sealing and seal ring between piston rod and the hydraulic cylinder.
As improvement, the front end of hydraulic cylinder is provided with mounting hole, and the rear end of described piston rod also is provided with mounting hole.
Hydraulic damper is installed on the bicycle, can be installed in each position of vehicle body through the mounting hole at two ends, during use; Vehicle body shakes, and piston rod is travelled forward by force urges piston rod, piston ring, and then piston ring promotes hydraulic oil in oil storage cylinder; Spring seat is owing to be wholely set pressure spring, spring generation elastic strain with piston rod; When external force disappeared, piston rod was then because the effect of elastic force returns to original position.Oil pressure can be regulated through oil pressure regulator,, the elasticity coefficient of spring can be adjusted through the position of adjustment regulation cock on screw thread.
The beneficial effect of the utility model is: the utility model carries out damping through hydraulic structure, even knight's body weight is bigger, or vibrations are bigger, also can play good damping effect.
(4) description of drawings
Fig. 1 is the main TV structure schematic representation of the utility model.
Fig. 2 is the part-structure schematic representation of the utility model.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Like Fig. 1, shown in 2; A kind of hydraulic damper that is used for bicycle comprises hydraulic cylinder 3, is provided with piston in the hydraulic cylinder 3; Piston comprises piston rod 9 and the piston ring that is connected piston rod 8; Piston rod 9 extends back, and the rear end of piston rod is provided with a spring seat 5, and the rear of spring seat is provided with mounting hole 7.The outer surface of hydraulic cylinder 3 is provided with screw thread, and a regulation cock 2 is set on the screw thread, and regulation cock 2 can be adjusted at the position on the screw thread, thus the spacing between adjustment and the spring seat.An also sheathed spring 4 on the hydraulic cylinder, an end of spring connects spring seat 5, and the other end connects regulation cock 2, and hydraulic cylinder connects an oil storage cylinder 1, and oil storage cylinder connects an oil pressure regulator 6.Be provided with oil sealing 10 and seal ring between piston rod and the hydraulic cylinder.The front end of hydraulic cylinder is provided with mounting hole 7.
Hydraulic damper is installed on the bicycle, can be installed in each position of vehicle body through the mounting hole 7 at two ends, during use; Vehicle body shakes, and vibration damper is travelled forward by force urges piston rod 9, piston ring 8, and then piston ring promotes hydraulic oil in oil storage cylinder 1; Spring seat 5 is owing to be wholely set with piston rod, pressure spring 4 simultaneously, and elastic strains take place in spring 4; When external force disappeared, piston rod was then because the effect of elastic force returns to original position.Oil pressure can be regulated through oil pressure regulator,, the elasticity coefficient of spring can be adjusted through the position of regulation cock on screw thread.The utility model carries out damping through hydraulic structure, even knight's body weight is bigger, or vibrations are bigger, also can play good damping effect.

Claims (3)
