Description

Technical Field

[0001] The utility model relates to the technical field of folding structures of scooters, in particular to a folding pole structure of a scooter. Background Art

[0002] A scooter is a means of transportation, mainly suitable for urban roads or relatively flat roads. Compared with other means of transportation such as bicycles, it is lighter in weight and smaller in size, making it easier to carry and store.

[0003] Scooters generally have a folding function for easy storage, but the upright pole and the wheel in the existing folding structure of the scooter are generally an integrated structure. When the upright pole is folded, the wheel fixed thereto will be lifted up together, so when carrying the folded scooter, the lifted wheel is easy to stain clothes; and the upright pole of the existing scooter generally has a telescopic function, which is to adjust the tightness of the top of the upright pole by a bolt clamp buckle, so as to achieve the height adjustment of the internal telescopic rod, but because the inner side of the upright pole is in direct contact with the outer side of the telescopic rod, and the scooter is folded and used frequently, it is easy to cause the paint layer on the outer side of the bottom end of the telescopic rod to wear off, resulting in the internal metal being exposed, which is easy to be affected by moisture and rust, affecting the telescopic. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the wheels of the existing folding scooter are easy to stain clothes after being folded, and the friction between the vertical rod and the telescopic rod is relatively frequent, which easily causes the telescopic rod to lose paint and rust.

[0005] To solve the above problems, the technical solution adopted by the utility model is a folding scooter upright pole structure, comprising a frame, a support frame fixed at one end of the frame, a front wheel frame being provided in the middle of the support frame for limited rotation, a folding structure being provided on the upper side of the frame next to the support frame, the folding structure comprising a support rod fixed on the upper side of the frame, a folding rod being hinged on the top end of the support rod, a limiting ring sleeve being fixed at one end of the folding rod, a rod sleeve being provided on the inner side of the limiting ring sleeve for limited rotation, an upright pole being provided on the inner side of the rod sleeve, a hexagonal mounting boss being fixed on the top end of the front wheel frame, a hexagonal mounting groove being provided on the lower side of the upright pole, a plug-in groove being provided on the top end of the upright pole, a telescopic rod being provided slidingly in the plug-in groove, and a bushing being fixed on the outer side of the telescopic rod at the inner top end of the plug-in groove.

[0006] As a further solution of the utility model: a front wheel is rotatably provided at the bottom end of the front wheel frame, a rear wheel frame is fixed at the other end of the frame, and a rear wheel is rotatably provided in the rear wheel frame.

[0007] As a further solution of the utility model: a handlebar is provided at the top of the telescopic rod to facilitate control of the driving direction.

[0008] As a further solution of the utility model: a clamping ring structure is provided on the outer side of the top end of the vertical pole, which is the same as the clamping ring structure in the prior art, and the structure is an open ring sleeve, which is fastened by bolts and is used to clamp the telescopic rod to fix its position.

[0009] As a further solution of the utility model: a fastening bolt is rotatably provided on the outer side of the rod sleeve, one end of the fastening bolt abuts against the outer side of the vertical pole, and the fastening bolt is rotated to hold the vertical pole, thereby preventing the vertical pole from moving in the rod sleeve.

[0010] As a further solution of the utility model: the vertical rod is inserted into the hexagonal mounting groove and connected to the front wheel frame through the hexagonal mounting boss, so that the vertical rod can drive the front wheel frame to rotate, so as to adjust the driving direction.

[0011] Compared with the prior art, the utility model has the following advantages: the utility model adds a bushing structure, and by arranging the bushing between the vertical pole and the telescopic pole, the friction force on the outer side of the telescopic pole can be reduced, so that the protective paint on the outer side of the telescopic pole is not easily rubbed off; and the utility model separates the vertical pole structure from the front wheel and adopts a combined structure, which can prevent the vertical pole from moving the position of the front wheel when folding, so that the front wheel will not tilt up, so it is not easy to dirty clothes when moving.
