Abstract

The utility model relates to a kind of stepless pressure regulation fitness equipment based on magnetic flow liquid.This device is comprised of frame, back cushion, handle, pressure damper, and wherein pressure damper is comprised of piston rod, housing, back-up ring, travel switch, back-moving spring, piston, solenoid, magnetic flow liquid.After solenoid energising, magnetic flow liquid becomes the Bingham fluid of high viscosity, lazy flow from original New ton fluid moment, forms the power of an obstruction arm motion.Described travel switch is arranged on the two ends of housing, when both sides piston movement is when being enough to touch the travel switch at housing two ends, and system auto-breaking, damping pressure pop-off, due to the effect of middle back-moving spring, thereby realizes automatically reseting of piston.This device can also pass through to change the size of electric current, thereby changes magnetic flow liquid magnetic field intensity around, realizes the electrodeless variation to damping pressure, reaches the arm strength requirement that meets different crowd, fully demonstrates the human features of this fitness equipment.

Description

A kind of stepless pressure regulation fitness equipment based on magnetic flow liquid
Technical field
The utility model relates to fitness equipment device, especially relates to the fitness equipment device that adopts magnetic flow liquid to produce damping pressure.
Background technology
Along with the lifting of people's living standard, body-building, fitness, motion have become an indispensable part in people's life.Just because of this, be flooded with on the market now various, principle and the different exercise and fitness equipment of function.Be exactly the most simply with pulling the elastic pulling force device of stretching, also have the chest expander of many other types.In fact, as the U.S. Patent No. 3 of authorizing Cencing on August 27th, 1963,101, described in 944, a kind of typical body-building device comprises a both hands sliding part, user can promote this both hands sliding part along a sliding surface, put, or the position of going down on one's kness is return in the position of in the past bowing thereby user's health is stretched over anterior prone position from the position of going down on one's kness.
But all there are some shortcomings in most of chest expanders.For example, this class body-building apparatus has very strong bounce-back, and this not only can cause spraining of health, and the result of exercise is often got half the result with twice the effort, and more serious also certain accident can occur.Also having, lack adjusting device accurately and fast, is also the major defect of most types of exercise device to adapt to different crowd or different operating environment.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can, by changing the parameter of self, temper thereby can adapt to different crowd the fitness equipment requiring.
In order effectively to solve the deficiency as above of fitness equipment, the utility model is realized as follows: a kind of stepless pressure regulation fitness equipment based on magnetic flow liquid is by frame, back cushion, handle, core apparatus pressure damper forms, and wherein the core pressure damper of device is by piston rod, housing, back-up ring, travel switch, back-moving spring, piston, solenoid, magnetic flow liquid forms.Described back-up ring, travel switch, back-moving spring, piston, solenoid, magnetic flow liquid is all arranged on enclosure interior.Travel switch is arranged on housing two ends, touches the travel switch at two ends, thereby realize auto-breaking when user shifts piston onto housing two ends by handle.Between two described pistons, with back-moving spring, connect, between them, be provided with again two back-up rings, effect due to back-moving spring when electric current power-off is withdrawn into original position by two pistons, finally by back-up ring and back-moving spring acting in conjunction, piston is placed in to a stable state, waits for circulation next time.Described solenoid, on piston, leaves the gap of 2mm and passes through for magnetic flow liquid between piston and housing internal diameter.When solenoid is switched on, at piston, between housing and gap, can form magnetic circuit.By changing, by the electric current of solenoid, can adjust damping pressure to adapt to the exercise requirement of different crowd.
The good effect of a kind of stepless pressure regulation fitness equipment based on magnetic flow liquid described in the utility model is: on the basis of original non-adjustable damping pressure fitness equipment, by regulating solenoid current size, thereby change magnetic flow liquid magnetic field intensity around changes the function that the viscosity of magnetic flow liquid reaches device stepless pressure regulation.Due to the response speed of magnetic flow liquid very fast (millisecond magnitude), and reversible special nature, this means and can select in a kind of mode of simple adjusting electric current the damping pressure of fitness equipment, thereby can adapt to various crowds' exercise requirement.
Accompanying drawing explanation
Fig. 1 is the utility model outside drawing.
Fig. 2 is the structural representation of the utility model core pressure damper.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
In Fig. 1, a kind of stepless pressure regulation body-building apparatus based on magnetic flow liquid of the utility model is by frame 1, back cushion 2, and handle 3, core pressure damper 4 forms.
In Fig. 2, a kind of stepless pressure regulation body-building apparatus based on magnetic flow liquid of the utility model, its core pressure damper 4 comprises piston rod 5, housing 6, back-up ring 7, travel switch 8, back-moving spring 9, piston 10, solenoid 11, magnetic flow liquid 14.
Back-up ring 7, travel switch 8, back-moving spring 9, piston 10, solenoid 11, magnetic flow liquid 14 are all arranged on housing 6 inside.Travel switch 8 is arranged on housing 6 two ends, touches the travel switch 8 at two ends, thereby realize auto-breaking when user shifts piston 10 onto housing 6 two ends by handle 3.Between two described pistons 10, with back-moving spring 9, connect, between them, be provided with again two back-up rings 7, effect due to back-moving spring 9 when electric current power-off is withdrawn into original position by two pistons 10, finally by back-up ring 7 and back-moving spring 9 actings in conjunction, piston 10 is placed in to a stable state, waits for circulation next time.Described solenoid 11, on piston 10, leaves the gap 13 of 2mm and passes through for magnetic flow liquid 14 between piston 10 and housing 6 internal diameters.When solenoid 11 energising, at piston 10, between housing 6 and gap 13, can form magnetic circuit 12.By changing, by the electric current of solenoid 11, can adjust damping pressure to adapt to the exercise requirement of different crowd.
First, solenoid 11 is in "on" position, now at piston 10, between housing 6 and gap 13, can form magnetic circuit 12, when user promotes piston 10 by handle 3 when, effect due to pressure, magnetic flow liquid 14 flows to middle by the two ends of housing 6 by gap 13, when flowing through gap 13, existence due to the magnetic field 12 of radial direction, the flow direction of magnetic flow liquid 14 is perpendicular to the direction in magnetic field 12, it is large that the viscosity of magnetic flow liquid 14 becomes rapidly, and then damping pressure strengthens, make user need to go to push away by previous set power from the moment of pushing handle 3, when piston 10 touches travel switch 8, system auto-breaking, travel switch 8 postpones a period of time (piston 10 moves to the required time of original position from housing 6 two ends) magnetic circuit and becomes the fluid state that liquid 14 returns to original low-viscosity at once.Because the effect of back-moving spring 9 is withdrawn into original position by two pistons 10, finally by back-up ring 7 and back-moving spring 9 actings in conjunction, piston 10 is placed in to a stable state, electric current is connected, and waits for circulation next time.
