Description

Height-adjustable convenient bicycle saddle

Technical Field

The utility model relates to a bicycle field, concretely relates to convenient saddle of height-adjusting.

Background

Saddle is for the people to take and with the bicycle accessory of hip direct contact, and in order to adapt to the people of different heights can both be comparatively comfortable seat and use the bicycle on the cushion, saddle adjusting device can all be installed to the saddle bottom, current cushion adjusting device is the mechanical structure of bolt tightening formula, the fastening bolt below the user unscrews saddle earlier, then the pull rod of adjustment cushion bottom stretches out the height of bicycle frame, it just can adjust and confirm the cushion height to screw up the bolt at last, this kind of traditional cushion adjusting device has simple structure, low cost's advantage, but the defect lies in, screw up or unscrew the bolt and need great drive power, if meet the rusty difficult twisting of bolt and move more, difficult to use to woman or child, the cushion is adjusted inconveniently, the dumb.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides a height-adjusting's convenient saddle, concrete technical scheme is as follows:

A height-adjustable bicycle saddle comprises a saddle body, a lifting cylinder body, a shell, a piston rod, an adjusting handle and an air chamber channel switch, wherein the lifting cylinder body is arranged at the bottom of the saddle body and is movably arranged in the shell, an air chamber is arranged in the lifting cylinder body, high-pressure nitrogen is filled in the air chamber, a piston is arranged in the air chamber and connected with a piston rod, the lower end of the piston rod penetrates through the bottom of a shell fixedly arranged on the lifting cylinder body, the piston divides the air chamber into an upper air chamber and a lower air chamber, an adjusting handle is hinged above the lifting cylinder body, one end of the adjusting handle is contacted with the upper end of an air chamber channel switch, the lower end of the air chamber channel switch extends into the lifting cylinder body, and the air chamber channel switch is blocked, when the cushion body needs to be heightened, the adjusting handle is rotated to enable the air chamber channel switch to move downwards to open the air chamber channel, and the upper air chamber is communicated with the lower air chamber to enable the lifting cylinder body to move upwards.

As an optimized proposal of the utility model, the bottom of the lifting cylinder body is provided with a cushion pad.

As an optimized scheme of the utility model, install the sealing washer between piston rod, air chamber channel switch and the lift cylinder body.

As a preferred aspect of the present invention, the housing is installed in a bicycle frame.

As an optimized proposal of the utility model, the cushion body is provided with a plurality of air holes.

Has the advantages that: for traditional bolt adjustment saddle altitude construction, the utility model discloses saddle structural design is reasonable, when the cushion body need heighten, rotate adjustment handle and make air chamber channel switch move down and open the air chamber passageway, go up the air chamber, the lower air chamber communicates with each other, thereby the effect that receives on the piston is greater than the lower extreme effort greatly and leads to the lift cylinder body to shift up, thereby the lift cylinder body takes the cushion body to rise to and loosens adjustment handle after suitable height, air chamber channel switch resets and closes the air chamber passageway, altitude mixture control is convenient, swiftly, need not very big drive power, be applicable to different crowds.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

As shown in figure 1, a height-adjustable bicycle saddle pad, including a saddle body 1, lift cylinder 2, shell 3, piston 4, piston rod 5, adjustment handle 6 and air chamber channel switch 7, seat body 1 bottom installation lift cylinder 2, lift cylinder 2 movable mounting is in shell 3, the inside air chamber that is equipped with of lift cylinder 2, the air chamber is equipped with high-pressure nitrogen gas in, air chamber internally mounted piston 4, piston 4 connects piston rod 5, the piston rod 5 lower extreme passes lift cylinder 2 fixed mounting shell 3 bottom, piston 4 divides the air chamber into upper air chamber 81 and lower air chamber 82, upper air chamber 81 and lower air chamber 82 pass through air chamber channel 83 intercommunication, lift cylinder 2 top articulates adjustment handle 6, adjustment handle 6 one end contacts with air chamber channel switch 7 upper end, air chamber channel switch 7 lower extreme stretches into in the lift cylinder 2.

specifically, 2 bottoms of lift cylinder body are installed blotter 9, and blotter 9 can effectively avoid 2 decline rigid collision shells 3 damages of lift cylinder body, and in addition, installation sealing washer 10 between piston rod 5, air chamber channel switch 7 and the lift cylinder body 2, sealing washer 10 reinforcing gas tightness avoids high-pressure nitrogen to leak.

Specifically, the shell 3 is installed in the bicycle frame, can be fine fix the position of shell 3, and the installation is nimble convenient, and in addition, the cushion body 1 is equipped with a plurality of bleeder vents, does not feel sultry when sitting.

The working principle is as follows: when the cushion body 1 needs to be heightened, the adjusting handle 6 is rotated to enable the air chamber channel switch 7 to move downwards to open the air chamber channel 83, the upper air chamber 81 and the lower air chamber 82 are communicated, the action on the upper end of the piston 4 is greatly larger than the action force on the lower end, so that the lifting cylinder body 2 is moved upwards, the lifting cylinder body 2 drives the cushion body 1 to ascend to a proper height, the adjusting handle 6 is loosened, the air chamber channel switch 7 resets to close the air chamber channel 83, and the upper air chamber 81 forms a closed space to meet the downward pressure of a rider sitting on the cushion body 1.

The above description is provided for the purpose of describing the present invention in more detail with reference to the preferred embodiments, and it should not be construed that the present invention is limited to these descriptions, and it will be apparent to those skilled in the art that the present invention can be implemented in many ways without departing from the spirit and scope of the present invention.
