Folding exercise bicycle

Abstract

The invention discloses a folding exercise bicycle, which comprises a pedal unit, a seat unit, a front support pipe and a rear support pipe which are rotatably connected through a rotating shaft. Thepedal unit is arranged at the lower part of the front support pipe, and the seat unit is arranged at the upper end of the front support pipe. At least one connecting rod is arranged between the frontsupport pipe and the rear support pipe, and the connecting rod is rotatably connected with the front support pipe at a place between the first end or the first end and the second end of the connectingrod; the rear support pipe is provided with a slider which slides up and down with respect to the rear support pipe, the second end of the connecting rod is rotatably connected with the slider, and alocking mechanism is arranged between the slider and the rear support pipe for locking the slider on the rear support pipe after the slider slides with respect to the rear support pipe for a certaindisplacement. The folding exercise bicycle has the advantages of strong load-bearing capacity, good structural stability, not easy to generate shaking when riding, good user experience sense, and canbe used by users with small height.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a folding exercise bike. Background technique [0002] An exercise bike, also called a riding platform, is a device with a damping system for in-situ riding exercises. It uses the damping system to give the bike a durable and stable riding resistance, simulating the actual riding state, and the training is not affected by the weather. And the impact of location, so that trainers can enjoy the fun of cycling at any time, so it is very popular. The exercise bike of the prior art is generally all arranged to be foldable for the convenience of packaging and transportation; its structure generally includes a frame unit composed of cross-hinged seat tubes and support tubes, and the bottom of the seat tube is provided with a stepping unit; When the frame unit is opened, it is limited by the stopper welded on the seat tube, so a scissors-like opening and closing mechanism is f...

AI Technical Summary

Problems solved by technology

The exercise bike with this structure has the following deficiencies during use: firstly, the fixing after adjusting the opening and closing angle between the front support tube and the rear support tube is to rely on the plug-in fit between the bolt and the through hole and the positioning hole to fix the front support Tube and rear support tube, the gravity carried by the front support tube and rear support tube is fully applied on the bolt, so the load-bearing of the exercise bike is small, and the maximum load-bearing does not exceed 220 pounds; The front support tube and the rear support tube are fixed by the insertion fit between them, which not only makes the structural stability between the front support tube and the rear support tube poor, it is easy to shake when riding, and the user experience is poor. It is also inconvenient to operate; moreover, the axis of rotation at the hinged place of the front support tube and the rear support tube is in the middle of the front support tube, and the front support tube is restricted by the lower limit mechanism when it rotates downwards, thus causing the top of the front support tube to The seat cannot be lowered to the lowest position, and the cooperation between the seat and the pedal unit is not coordinated, which cannot meet the needs of users with smaller heights
