Abstract
The utility model discloses an adjustable backrest device of an exercise bicycle. The adjustable backrest device comprises a backrest body and a seat sliding base where the backrest body is installed. The seat sliding base comprises a top face and two mutually-parallel lateral faces connected below the top face. The backrest body comprises a U-shaped frame and a horizontal transverse rod which is connected to the position, close to the two end portions, of two lateral rods of the U-shaped frame, the lower end portion of the U-shaped frame is respectively hinged to the two lateral faces of the seat sliding base, and a backrest connecting piece is fixedly connected to the transverse rod. A self-locking gas spring is connected to the backrest connecting piece, and a gas spring connecting base connected to the other end of the self-locking gas spring is arranged on one lateral face of the seat sliding base. An L-shaped backrest adjusting rod abutting against a valve rod of the self-locking gas spring is hinged to the gas spring connecting base. Inclination angles of a backrest chair can be conveniently adjusted through the L-shaped backrest adjusting rod, and the adjustable backrest device is simple and firm in structure, convenient to use and low in production cost.
Description
Technical field
The utility model belongs to the body building car structure technical field, the adjustable back device that is specifically related to use on exercycle.
Background technology
Exercycle, also referred to as cycle ergometer, is divided into two kinds of vertical type, backrest-type exercycles, can adjust the intensity while moving, and plays the effect of body-building, so people call exercycle to it.The aerobic fitness equipment that belongs to typical simulation outdoor exercises also is called as the cardiorespiratory training equipment.Be mainly by the health long period, suitably the motion of intensity promotes cardiovascular motion, accelerates metabolism, strengthens heart and lung functions, thereby improves the physique of human body.Existing body building car structure is comparatively complicated, and parts are various, the assembling trouble, and production cost is high.The mechanisms such as the seat on exercycle, backrest regulate inconvenient in addition.
Summary of the invention
The purpose of this utility model is: the deficiency existed for prior art provides that a kind of structure is comparatively simplified, the adjustable back device of exercycle firmly.
For realizing the purpose of the utility model, be achieved by the following technical solutions: a kind of adjustable back device of exercycle, include backrest and in order to the seat slide of backrest to be installed, described seat slide includes an end face and two sides that are parallel to each other that are connected to the end face below; Described backrest includes a U-shaped framework and is connected to the horizontal cross bar of U-shaped framework two side levers near the position, both ends, and the bottom of U-shaped framework is hinged on respectively seat slide two sides, is fixedly connected with a backrest connector on cross bar; Be connected with a self-locking air spring on the backrest connector, on a side of seat slide, be provided with the air spring Connection Block be connected with the self-locking air spring other end; Be hinged with the L shaped backrest adjusting lever that a valve rod with the self-locking air spring offsets on the air spring Connection Block.
While needing to adjust the angle of backrest, only need upwards to pull the backrest adjusting lever, the backrest adjusting lever is pushed down the valve rod of self-locking air spring, the piston of self-locking air spring can be movable, at this moment can manually adjust the angle of backrest, after arriving proper angle, unclamp the backrest adjusting lever, the self-locking air spring is replied lockup state, and backrest is fixed on current angle.
As preferred version: two side levers middle parts of described U-shaped framework are provided with to the bent rod section of backrest rear direction bending, and on two side levers, the bar section of bent rod section upper and lower parallels.
Compared with prior art, the beneficial effects of the utility model are: by L shaped backrest adjusting lever, can to the angle of inclination of chair, be adjusted easily, simple in structure firm and very easy to use, production cost is low.
