Bicycle is very extensive as a kind of light vehicular applications, existing bicycle seat all is fixedly connected on the car body according to user's proper height mostly, so that bicycle about the user, make that so also the leg curvature degree was bigger when the user stepped on car at ordinary times, degree long or leg curvature through the long steeper road of the gradient time because when stepping on car makes that greatly stepping on ten minutes requires great effort when user's running time, often need with shank stretch step on car could be laborsaving, make the user not to be sitting in like this and step on car on the seat, and general bicycle seat bolt up is on car body, is not to use that the person can regulated at will when stepping on car.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, bicycle seat lifter that in motion can regulated at will bicycle seat height.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of bicycle seat lifter, comprise strut bar that is arranged on the bottom, seat and the connection pipe that is arranged on the vehicle body, this strut bar is sleeved in the connection pipe, be provided with spring in the described connection pipe, have guide groove at the sidewall of connection pipe, this guide groove side is provided with draw-in groove, described strut bar is provided with and the cooresponding locating dowel pin of draw-in groove, this strut bar is positioned at the spring top, and the locating dowel pin on it places between the guide groove, also is provided with fixture block on the strut bar rear wall.
The beneficial effects of the utility model are: the user is when stepping on car, by shank extruding strut bar, make the locating dowel pin on the strut bar break away from draw-in groove, strut bar rises under the elastic-restoring force of spring, drive the top that locating dowel pin rises to guide groove, the top that fixture block on its rear wall blocks connection pipe is positioned at this height with the seat, under this height, leg curvature is less when making the user step on car, step on car for a long time or when running into domatic long or steeper road surface, also can compare easily, can not make when stepping on car hard painstakingly because leg curvature is big, when the user need get off, forward lean drove strut bar and moves forward, and the fixture block on it leaves the connection pipe top, the seat moves downward with length of spring compressed strut bar under the gravity pressure of human body, locating dowel pin on the strut bar prolongs guide groove and glides, and when the moment shank extruding seat that the user gets off snaps in locating dowel pin in the draw-in groove, makes seat return to normal height, allow the user easily get off, very convenient to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of bicycle seat lifter, comprise strut bar 1 that is arranged on the bottom, seat and the connection pipe 2 that is arranged on the vehicle body, this strut bar 1 is sleeved in the connection pipe 2, is provided with spring 3 in the described connection pipe 2, sidewall at connection pipe 2 has guide groove 4, these guide groove 4 sides are provided with draw-in groove 5, and described strut bar 1 is provided with and draw-in groove 5 cooresponding locating dowel pins 6, and this strut bar 1 is positioned at spring 3 tops, locating dowel pin 6 on it places between the guide groove 4, also is provided with fixture block 7 on strut bar 1 rear wall.
The user is when stepping on car, by shank extruding strut bar 1, make the locating dowel pin 6 on the strut bar 1 break away from draw-in groove 5, strut bar 1 rises under the elastic-restoring force of spring 3, drive the top that locating dowel pin 6 rises to guide groove 4, the top that fixture block 7 on its rear wall blocks connection pipe 2 is positioned at this height with the seat, under this height, leg curvature is less when making the user step on car, step on car for a long time or when running into domatic long or steeper road surface, also can compare easily, can not make when stepping on car hard painstakingly because leg curvature is big, when the user need get off, forward lean drove strut bar 1 and moves forward, and the fixture block 7 on it leaves connection pipe 2 tops, the seat moves downward with length of spring compressed strut bar 1 under the gravity pressure of human body, locating dowel pin 6 on the strut bar 1 prolongs guide groove 4 and glides, and when the moment shank extruding seat that the user gets off snaps in locating dowel pin 6 in the draw-in groove 5, makes seat return to normal height, allow the user easily get off, very convenient to use.
The utility model is simple in structure, easy to use, extensively is installed in to be used for the bicycle seat lifter of regulated at will seat height in the process of moving on the bicycle.
