Abstract

The utility model relates to an automatic height adjustment device of a bicycle saddle, which is characterized in that the automatic height adjustment device is arranged between a vertical tube of the bicycle saddle and a vertical tube of the bicycle frame. The device consists of a pawl, a pawl base, a controller, a spring of a bicycle saddle tube and a bearing pin. A glide fit is between the vertical tube of bicycle saddle and the vertical tube of the bicycle frame. The pawl is arranged on the pawl base. The controller is connected with the pawl. The spring of the bicycle saddle tube is arranged in the vertical tube of the bicycle frame. The bearing pin is installed in the vertical pin slot of the bicycle saddle. The utility model has a plurality of advantages. The height of the bicycle saddle decides the riding efficiency, speed and comfortableness. In the noisy street full of people and red lights, to reduce the height of the bicycle saddle is needed so that the feet can touch the ground at any time. If being in a spacious place or being against wind, to raise the bicycle saddle is a good choice. The height of the bicycle saddle can be adjusted when riding by adopting the technology so as to satisfy the demand for riding under different circumstances. The utility model has a low cost, which accounts for only 8 percent of the price of the cheap bicycles.

Description

A kind of height self-reacting device of bicycle saddle

(1) technical field:

The utility model relates to bicycle saddle, particularly a kind of height self-reacting device of bicycle saddle.

(2) background technology:

Existing all kinds of bicycle, in the process of riding, saddle height all can not be regulated voluntarily, brings certain trouble and discomfort for the people that rides.

(3) summary of the invention:

The purpose of this utility model is to design a kind of height self-reacting device of bicycle saddle, but it makes height regulated at will in riding of bicycle saddle, has made things convenient for the user.

The technical solution of the utility model: a kind of height self-reacting device of bicycle saddle, comprise saddle, saddle standpipe and cycle frame standpipe, it is characterized in that being equipped with between saddle standpipe and cycle frame standpipe the self-reacting device of a saddle height, the self-reacting device of said saddle height is by ratchet, pawl base, control piece, seatpillar spring and bearing pin constitute, it between saddle standpipe and the seat tube bearing fit, ratchet places on the pawl base, control piece is connected with ratchet, the seatpillar spring places in the cycle frame standpipe, and bearing pin is contained in the saddle standpipe cotter way.

Above-mentioned said control piece can be opened spring by backguy, ratchet, ratchet closes spring and constituted, backguy by ratchet open spring, ratchet closes spring and is connected with ratchet.

Working process of the present utility model is: saddle can be under the effect of seatpillar spring or rise or descend under the human body action of gravity.The high and low position of saddle is decided by the location of ratchet.Ratchet is controlled by backguy, and when backguy was relaxed state, ratchet closed spring ratchet is compressed, and saddle is in a high position; When backguy was tension, ratchet closed spring and promptly breaks away from ratchet, and ratchet is opened spring and begun to work, and produces the power that ratchet is thrown off, and when health lifts slightly, ratchet is promptly thrown off, and saddle drops to low level (cotter way and bearing pin offset) in the health action of gravity.

Above-mentioned said bearing pin has multiple action, and it can prevent the saddle rotation and be pulled out; It can do accurately location for ratchet; No matter saddle is in a high position or low level, and it all is main supporting part.

Preceence of the present utility model is: the height of bicycle saddle determined to ride efficient, speed and level of comfort, many these the low saddle height of will begging to surrender of, red light many busy street stream of people, bipod can land at any time, as empty ore deposit, against the wind, preferably high low seat, adopt present technique, can in the process of riding, regulate saddle height voluntarily, to satisfy the requirement of riding of different situations; Cost is low, only is equivalent to 8% of cheap bicycle price.

(4) description of drawings:

Accompanying drawing 1 is the scheme drawing of the height self-reacting device of the related a kind of bicycle saddle of the utility model at bicycle integral position place.

Accompanying drawing 2 is the integral structure scheme drawing of the height self-reacting device of the related a kind of bicycle saddle of the utility model.

Accompanying drawing 3 is Fig. 2 A-A place section-drawing.

Wherein: II is the self-reacting device of saddle height, and 1 is saddle, and 2 is the saddle standpipe, and 3 is the cycle frame standpipe, and 4 is ratchet, and 5 is pawl base, and 6 for backguy, and 7 open spring for ratchet, and 8 for ratchet closes spring, and 9 is the seatpillar spring, and 10 is bearing pin, and 11 is cotter way.

(5) specific embodiment:

Embodiment: a kind of height self-reacting device of bicycle saddle (seeing Fig. 1-3), comprise saddle 1, saddle standpipe 2 and cycle frame standpipe 3, it is characterized in that 3 of saddle standpipe 2 and cycle frame standpipes are equipped with the self-reacting device II (see figure 1) of a saddle height, the self-reacting device of said saddle 1 height is by ratchet 4, pawl base 5, backguy 6, ratchet is opened spring 7, ratchet closes spring 8, seatpillar spring 9 and bearing pin 10 constitute, be bearing fit between saddle standpipe 2 and the seat tube 3, ratchet 4 places on the pawl base 5, backguy 6 is opened spring 7 by ratchet, ratchet closes spring 8 and is connected with ratchet 4, seatpillar spring 9 places in the cycle frame standpipe 3, and bearing pin 10 is contained in the saddle standpipe cotter way 11 (seeing Fig. 2-3).

Claims
