Technical Field

The invention relates to the field of bicycles, in particular to a beach bicycle.

Background

The bicycle as a vehicle is integrated into the life of people, and along with the change of life style of people, various bicycles with a special purpose, which are obtained by improving on the basis of the bicycle, gradually enter the life of people.

Current can refer to chinese patent that publication number is CN210310723U, it discloses a snowfield sandy beach electric bicycle, including the pillar, pillar one end is fixed with the base, pillar one side is fixed with the fender, fender one side is opened there is the mounting groove, the inside sliding connection of mounting groove has the mounting panel, mounting panel one end is fixed with the fixed plate, mounting groove one side is opened there is first screw hole, fixed plate one side is opened there is the second screw hole, mounting panel one side is fixed with first stopper, first stopper both sides all are fixed with the spout, the inside sliding connection of spout has the slider, slider one side is fixed with the regulating block, regulating block one side is fixed with the handle, the regulating block bottom is fixed with the kelly. The brush is fixed at the bottom of the fender through the action of the first limiting block and the second limiting block, and when the brush is used, silt or snow blocks clamped in the anti-skid lines can be swept away, so that tires are kept clean all the time, and the brush is convenient to detach and clean or replace by a user.

The above prior art solutions have the following drawbacks: because the height and the leg length of each rider are slightly different, the seat and the frame of the bicycle are relatively fixed, so that the bicycle is inconvenient for people with different heights to ride and is inconvenient to use.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a beach bicycle, which achieves the effect of conveniently adjusting the height of a seat.

The technical purpose of the invention is realized by the following technical scheme:

the utility model provides a sandbeach bicycle, which comprises a carriage body, be equipped with the frame on the automobile body, the intermediate position of frame is equipped with the seat pipe, seat pipe department is connected with the saddle, be equipped with the adjusting part of adjusting the saddle between saddle and the seat pipe, the adjusting part includes adjusting screw and adjustable ring, adjusting screw's one end and saddle fixed connection, the other end insert in the seat pipe with seat pipe sliding connection, the adjustable ring cover is established on adjusting screw with adjusting screw threaded connection, the adjustable ring rotates with the seat pipe to be connected, be equipped with the direction subassembly between adjusting screw and the seat pipe.

Through adopting above-mentioned technical scheme, when needing the adjustment saddle, rotate the adjustable ring, adjustable ring and adjusting screw threaded connection, the adjustable ring rotates for adjusting screw reciprocates, and adjusting screw removes and drives the saddle and reciprocate, thereby realizes adjusting the height of saddle. When adjusting screw, direction subassembly leads adjusting screw for adjusting screw can only move along its axis, prevents adjusting screw circumferential direction, thereby guarantees that the saddle is in the position of ajusting, improves and rides passerby's comfort level. In addition, the height of the saddle is adjusted by the aid of the adjusting screw and the adjusting ring in a threaded matching mode, stepless adjustment can be achieved, and therefore the bicycle is suitable for people with different heights to ride.

The utility model discloses further set up to, the direction subassembly includes guide bar, guide way and guide block, and the one end fixed connection of saddle is kept away from to the one end and the adjusting screw of guide bar, and the other end inlays in the seat pipe, and the guide way is seted up on the inner wall of seat pipe, and the one end of guide block inlays in the guide way with guide way sliding connection, and the other end is connected with the guide bar.

Through adopting above-mentioned technical scheme, guide bar and adjusting screw fixed connection, adjusting screw drives the guide bar when reciprocating and reciprocates, and the guide bar reciprocates and drives the guide block and slide along the guide way, and the guide way limits the guide block for the guide block can only vertical removal, and unable circumferential direction, and then makes the unable circumferential direction of adjusting screw, prevents to ride the in-process, and the saddle takes place to rotate, increases the stability of saddle, improves the comfort level of riding passerby.

This practicality further sets up to, the side of guide bar has been seted up and has been held the groove, and the guide block inlays and is equipped with the elastic component in holding the inslot and holding between the groove.

Through adopting above-mentioned technical scheme, when needs take out the guide bar from the seat pipe in to the saddle maintain the operation such as, when the guide bar removed to guide block and adjustable ring butt, the guide block can restrict the guide bar and remove, and at this moment, the compression elastic component inlays the guide block in holding the inslot for the side of guide block flushes with the side of guide bar, thereby makes the guide bar can follow the roll-off between the adjustable ring smoothly, easy operation, convenient to use.

This practicality further sets up as, the elastic component is elastic spring, elastic spring's one end with hold inslot wall fixed connection, the other end and guide block fixed connection.

Through adopting above-mentioned technical scheme, when elastic spring was compressed, the guide block can inlay completely in holding the inslot for the guide bar can be smoothly followed the seat pipe and slided out. When the guide block inlays in the guide way when sliding, elastic spring can make the inner wall butt of guide block and guide way, increases the stability of guide block, and then improves the stability of saddle.
