Abstract

The invention relates to a bicycle system. An air cylinder 3 is inserted in a bicycle saddle tube 8, and the lower end of a saddle stem is fixedly connected with a piston to serve as a piston push-pull rod 1 to implement an inflating function; an air outlet tube is provided with an air seal 7, which can seal the air in the air cylinder to implement pneumatic buffering and damping functions; the wall of the air cylinder 3 is provided with a limit notch 13, the piston push-pull rod 1 is provided with a limit pin 10, and the limit notch 13 and the limit pin 10 can cooperate with each other to rapidly switch a saddle limiting function and the inflating function; a lock body 4 is fixed on a bicycle frame, and a handle which is mounted on an air nozzle also serves as a lock cylinder head 5 to implement a locking function. According to the bicycle, the conventional bicycles are improved, inflation, damping and locking are integrated, the convenience, comfort, safety and cost performance of bicycles are improved, and the bicycle is economical and practical.

Description

A kind of bicycle device

Technical field

The present invention relates to a kind of bicycle device.

Background technology

Nowadays social life rhythm but comes faster, and a large amount of self-propelled vehiclees not only brings very large pressure to city traffic, also causes great harm to environment simultaneously, and consumes a large amount of natural resourcess.Bicycle is as a kind of vehicle of environmental protection, and be deeply subject to liking of broad masses of the people, the present invention improves standard bicycle, integrate inflate, vibration damping and lock, improve the convenience of bicycle, traveling comfort and safety, economical and practical, add the cost performance of bicycle.

Summary of the invention

The object of the present invention is to provide a kind of simple mechanism that bicycle is integrated to inflate, vibration damping and lock function.

For achieving the above object, the present invention adopts following technical scheme:

At bicycle saddle tube inner sleeve cylinder, car saddle bar lower end and cylinder piston connect firmly as piston push-pull rod, realize inflating function by upper and lower tension and compression saddle; Have vertical slot and transverse groove in cylinder wall upper end, transverse groove is opened in the middle part of vertical slot, and piston push-pull rod arranges locating dowel pin, and it is spacing and inflate power and energy that both cooperations conveniently can realize saddle; Freeing pipe is provided with obturating system, enables cylinder seal gas up for safekeeping, the vibration of effective buffer saddle; Under saddle, be connected with the stage clip of suitable rigidity, seal gas up for safekeeping and stage clip combined action realizes saddle vibration damping; Outlet nozzle be installed handle as lock column cap be fixed on lock body on vehicle frame, form safety lock device around the freeing pipe three of wheel, to realize lock function.

The present invention improves standard bicycle, integrate inflate, vibration damping and lock, improve the convenience of bicycle, traveling comfort and safety, economical and practical, add the cost performance of bicycle.

Accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present invention;

Fig. 2 is the concrete structure schematic diagram of the position-limited trough of falling H type shown in Fig. 1.

The concrete structure schematic diagram of Fig. 3 valve shown by Fig. 1.

In figure, 1 saddle bar is held concurrently piston push-pull rod, 2 vibration damping stage clips, 3 cylinders, 4 lock bodies, 5 lock heads, 6 freeing pipes, 7 obturating systems, 8 pipes, 9 cylinder locking devices, 10 locating dowel pins, 11 saddles, 12 outlet nozzles, 13 position-limited troughs.

Detailed description of the invention:

Below in conjunction with drawings and Examples, the invention will be further described.

As shown in Figure 1, bicycle saddle tube inner sleeve cylinder 3, car saddle bar lower end and piston connect firmly as piston push-pull rod 1; Vertical slot and transverse groove is had in cylinder wall upper end, transverse groove is opened in the middle part of vertical slot, forms the position-limited trough 13 of H-shaped, piston push-pull rod 1 arranges locating dowel pin 10, as shown in Figure 2, position-limited trough 13 and locating dowel pin 10 coordinate that conveniently to realize saddle spacing and inflate power and energy; Cylinder 3 air extractor duct place establishes obturating system 7, cylinder 3 air extractor duct can be closed, enable its inside seal gas up for safekeeping, the vibration of effective buffer saddle 11; Below saddle 11, be connected with the vibration damping stage clip 2 of suitable rigidity, itself and seal gas combined action up for safekeeping and realize saddle 11 vibration damping; As Fig. 3, outlet nozzle be installed handle as lock column cap 5 with the lock body 4 be fixed on vehicle frame, form safety lock device around freeing pipe 6 three of wheel, to realize lock function.

Principle of work: when needing bicycle inflating, close obturating system 7, receive on bicycle tyre valve by outlet nozzle 12, rotating piston pull bar 1 makes locating dowel pin 10 screw out position-limited trough 13, and upper and lower tension and compression saddle 11 can realize the inflation to bike tyre; When inflation terminates, open obturating system 7, pressing saddle 11 makes cylinder seal a certain amount of gas up for safekeeping, and locating dowel pin 10 is screwed in position-limited trough 13, utilize the gas sealed up for safekeeping to form air damping and slow down piston push-pull rod 1 up-down vibration, by vibration damping stage clip 2 with seal gas shared pressure up for safekeeping and realize vibration damping; When bicycle storing, by freeing pipe 6 around wheel, lock column cap 5 inserts in the fixing lock body 4 of bicycle rack, and restriction rear wheel, realizes lock function.

Above detailed introduction is done to the specific embodiment of the invention.Described detailed description of the invention just understands core concept of the present invention for helping.It should be pointed out that for those skilled in the art, under the prerequisite not departing from inventive principle, can also carry out some improvement and modification to the present invention, these improve and modify the protection domain also belonging to the claims in the present invention.
