Problems solved by technology

At present, there is no report about adding a hydraulic cylinder to the spinning bike. A conventional hydraulic cylinder is basically composed of a cylinder barrel, a cylinder head, a piston, a piston rod and a sealing device. The import and export of hydraulic oil is realized. To adjust the flow of hydraulic oil, a flow regulating valve must be added. The entire system occupies a large volume, is heavy and is inconvenient to install.

Abstract

The invention discloses an adjustable hydraulic damper, comprising a piston cartridge, wherein a guide sealing cover is arranged at the top of the piston cylinder; a bottom cover is arranged at the bottom of the piston cylinder; a piston body capable of axially moving is arranged in the piston cylinder; a piston rod is fixedly connected to the piston body; the piston rod penetrates out of the guide sealing cover and is connected with an external mechanism; the piston body is provided with two damping holes which are identical in size and symmetrical in the axial direction; a fan-shaped valve capable of shielding the damping holes is arranged on one surface, facing the bottom cover, of the piston body; the fan-shaped valve is formed by two axially and symmetrically arranged fan-shaped pieces; the surface of each fan-shaped piece is provided with a wire slot used for clamping a brake cable; the side surface of each fan-shaped piece is provided with a groove; the surface of the piston body is provided with two limiting protruding blocks capable of being clamped into the grooves; and the limiting protruding blocks are arranged between the two damping holes. The adjustable hydraulic damper is compact in structure and small in occupied area, hydraulic oil circulation of the adjustable hydraulic damper can be achieved, resistance can be controlled, and the weight of a spin bike is greatly reduced.

Description

technical field [0001] The invention belongs to the field of fitness equipment, and in particular relates to an adjustable hydraulic damper and a spinning bicycle thereof. Background technique [0002] Nowadays, as young people are more and more interested in sports, in terms of exercise bikes, affected by external factors, many models of indoor exercise bikes, also known as spinning bikes, have gradually emerged. This type of indoor exercise bicycle has been widely used in places such as fitness clubs and families. Current spinning bikes all use belts to drive the inertial flywheel to rotate to achieve fitness. The transmission efficiency is not high, and when a fitness accident occurs, because of the inertial effect of the inertial flywheel, it is easy to brake not in time. For example, 1. Application No.: 201710003274.X, Invention Name: Magneto-rheological Intelligent Adaptive Bicycle, still using the drive wheel (6) to connect the wheel (1) through the belt (2); 2. Appl...
