Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power vehicles, in particular to a power vehicle which is convenient for adjusting the height. Background Art
[0002] "Fitness power bike" generally refers to a concept that combines fitness equipment and power vehicles. This vehicle combines the functions of an indoor fitness bike with the characteristics of a power vehicle, aiming to provide a way to exercise and drive the vehicle at the same time.
[0003] The existing seat post structure is mainly composed of two sections, namely a combining rod and a connecting rod. The connecting rod is connected to the bottom end of the seat, and the combining rod is fixed on the power bicycle frame. The connecting rod and the combining rod are clamped and fixed by a clamp. When the height needs to be adjusted, the clamp can be loosened and the relative position of the connecting rod and the combining rod can be adjusted to raise or lower the seat. After the adjustment is completed, it can be clamped again.
[0004] However, this structure mainly uses friction to fix the combining rod and the connecting rod. During riding, the seat of the power bike is easily offset due to the limited positioning function of the force of human body gravity, and when the friction gap is too large, the clamp cannot stably clamp the connecting rod, which poses certain safety hazards. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a power bike with easily adjustable height, which solves the problem that the seat of the power bike is easily offset during riding due to the limited positioning function of the force of human body gravity.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power bike that is easy to adjust in height, comprising a frame, a mounting tube, a connecting rod, a seat cushion and an adjustment assembly;
[0007] The mounting tube is vertically mounted inside the frame, the connecting rod is slidably connected inside the mounting tube, the seat cushion is assembled on the upper end surface of the connecting rod, and the adjustment assembly is arranged on the mounting tube to lock the connecting rod;
[0008] The adjustment assembly includes a threaded sleeve and a knob. The threaded sleeve is rotatably connected to the inside of the mounting tube, and the upper end of the threaded sleeve extends to the outside of the mounting tube. The knob is sleeved on the outside of the threaded sleeve. A threaded groove matched with the threaded sleeve is provided on the outer surface of the connecting rod, so that the threaded sleeve can drive the connecting rod to move up and down when it rotates, thereby adjusting the height of the seat cushion.
[0009] Furthermore, the installation tube is vertically provided with a cavity for the connecting rod to move up and down, and the upper end surface of the cavity is open.
[0010] Furthermore, a certain distance is maintained between the upper end surface of the threaded sleeve and the upper end surface of the mounting tube, and the knob is assembled at the distance between the threaded sleeve and the mounting tube.
[0011] Further, the adjustment assembly further comprises at least two guide rods and at least two side ears;
[0012] At least two of the guide rods are vertically mounted on the lower surface of the seat cushion, and at least two of the guide rods are arranged in a transverse interval, and at least two of the side ears are respectively mounted on both sides of the frame facing the at least two guide rods.
[0013] Furthermore, through holes for at least two guide rods to pass through are vertically opened inside at least two of the side ears.
[0014] Furthermore, the length of the guide rod is greater than the length of the connecting rod.
[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0016] The height-adjustable power bike can drive the threaded sleeve connected to the knob to rotate by rotating the knob. The threaded sleeve can drive the connecting rod and the seat cushion to move up and down during the rotation process through the effect of the threaded connection, so as to adjust the height of the seat cushion. At the same time, the seat cushion moves up and down, driving the two guide rods connected to the seat cushion to move up and down, and the guide rods slide up and down inside the two side ears respectively, so as to limit the seat cushion and improve the stability when the height is adjusted.
