Technical Field

The invention belongs to the technical field of scooters, and particularly relates to a scooter with an adjustable seat height.

Background

The scooter is a common motion product, compares and masters in the slide easier, and the scooter is accepted by people gradually, and it is fit for the use on multiple age layer, and the scooter is developing perfect balanced system to children more has good exercise effect, and children's scooter's kind is various, has different classifications according to different age brackets, and to some low age children, the scooter that has the bedplate is more suitable, and its operation requirement is low, and stability is better.

However, the seat board of the existing scooter is fixed and can not be adjusted, the height of the seat can not be adjusted according to the requirements of different age groups, and the comfort degree of the child during exercise can not be guaranteed.

Disclosure of Invention

The invention mainly solves the technical problem of providing a scooter with an adjustable seat height, which adjusts the seat height and ensures the comfort of children during exercise.

In order to solve the technical problems, the invention adopts a technical scheme that: a scooter with an adjustable seat height comprises a base, front wheels, rear wheels, an operating pipe and a seat, wherein the front wheels and the rear wheels are respectively positioned on the front side and the rear side of the base;

the lower extreme rotatable coupling of lifter in the base, the upper segment cover of lifter has the stand pipe, the internal surface of stand pipe is equipped with a plurality of along the direction recess of the axial setting of stand pipe, the surface of lifter is equipped with the gib block so that the stand pipe slides from top to bottom along the direction of gib block, the upper end of stand pipe is equipped with the knob that the drive seat ascended and descended.

Furthermore, the support frame is "U" type support frame, the lower extreme rotatable coupling of support frame in the base, the lower surface on seat is equipped with a plurality of and support frame assorted draw-in groove, and the support frame card is gone into different draw-in grooves in order to adjust the height on seat.

Furthermore, a pressing plate is installed below the seat, a bolt penetrates through the pressing plate to be connected with the seat, and a pressing spring is arranged between the pressing plate and a raised head of the bolt so that the pressing plate presses the clamping groove to prevent the supporting frame from being separated from the clamping groove.

Furthermore, the upper end surface circumference of the operation tube is provided with a plurality of positioning grooves matched with the knob, and the knob is clamped in the positioning grooves to limit the rotation of the lifting rod.

Further, the outer diameter of the knob is larger than the inner diameter of the operation tube.

Further, the outer diameter of the guide tube is equal to the inner diameter of the operation tube.

Furthermore, the operation tube is provided with a yielding groove corresponding to the connecting piece.

Further, the front wheel is mounted on a connecting rod, the connecting rod is connected with a pipe sleeve, and the pipe sleeve is fixed on the operating pipe.

The invention has the following beneficial effects:

according to the invention, the connecting piece is arranged at the front end of the seat, the connecting piece is in threaded connection with the lifting rod, the lifting rod is positioned inside the operating tube, and the support frame for supporting the seat is arranged below the seat, so that the lifting rod is driven to rotate by rotating the knob after the guide tube is lifted, the height of the seat is adjusted, the support frame can be clamped into different clamping grooves to adapt to the height of the seat, and the comfort level of the child during exercise is ensured;

a pressing plate is arranged below a seat, a bolt penetrates through the pressing plate to be connected with the seat, and a pressing spring is arranged between the pressing plate and a raised head of the bolt so that the pressing plate presses a clamping groove to prevent a support frame from being separated from the clamping groove.
