Description

Magnetic control multifunctional trainer

Technical field

The utility model relates to a kind of health and fitness facilities, particularly a kind of magnetic control multifunctional trainer that provides different class resistances by magnetic control.

Background technology

At present, the fitness training machine structurally mainly comprises: frame, assembly pulley, the main stay cord of walking around assembly pulley and polylith balancing weight, the end of main stay cord is connected with the balancing weight lifting device.The pulling force of fitness equipment is to rely on the weight of balancing weight to provide, and the grade of pulling force size also is to rely on the quantity of adjusting balancing weight to regulate.The sporter uses this fitness equipment, at the maximal end point of exerting all one's strength a kind of strong pulling force is arranged, and when action is replied in operation, has a kind of sensation of being drawn meeting, if do not note causing easily muscle damage.

Deficiency between this traditional fitness training machine, the applicant has designed a kind of magnetic control system, its structure as shown in Figure 1, form and comprise magnetic control wheel 7 and tension, magnetic control wheel 7 comprises that flywheel 32, inwall are provided with the magnetite stator 34 of magnetite (not drawing among the figure), this magnetite stator 34 is corresponding with flywheel 32, and tension comprises back and colludes sheet 314, adjusts line 5, is fixedly coupled piece 345 with magnetite stator 34 movable ends.Pulling is adjusted line 5 to motionless gear, can adjust the distance between magnetite stator 34 and the flywheel 32, thereby obtain the gear of different dynamics by the quantity that changes cutting magnetic line, novel structure, the dynamics of this magnetic control system are easy to adjust, and stop Shi Buhui and produce pull-back forces, so the sporter can not pull a muscle.All the other labels schematically as follows among Fig. 1: be coupling sleeve pipe, 332-of 31-pedestal, 311-side plate, the external support of 313-, 321-center axle bed, 33-axle, 331-locks assembly, 341-fulcrum, 343-blend stop, 344-side strip, 41-pinch roller, 42-pinch roller stator, 43-extension spring, 8-pressing wheel device.

Nowadays, this magnetic control system relies on its outstanding having a few and performance, become the focus and the development trend in body-building apparatus field, the practice of this magnetic control system also becomes the difficult problem of a puzzlement several years simultaneously, and the technical bottleneck of its most critical is how to make the fitness equipment homing.

Through years of researches, the applicant designs the recovery that utilizes spring to realize fitness equipment, and applied for Chinese patent on June 25th, 2003: magnetic control weight puller system, the patent No.: 03264799.9, to the U.S. patent application is proposed subsequently, and (US 6,857,993B2) to have obtained the novel patent of U.S. utility.As Fig. 2, shown in Figure 3, the magnetic control puller system of this magnetic control weight puller system, mainly include magnetic control wheel 7 and tension 10 thereof, belt pulley 3 by the coaxial bearing connection, great wheel 2, little runner 22, also has a resetting means 9, this magnetic control wheel 7 is coaxially connected with a belt pulley 72, this belt pulley 72 is by belt 71 and belt pulley 3 sockets, be wound with stay cord 8 on the great wheel 2, one end of this wiring 8 and great wheel 2 are fixing, the other end is fixedlyed connected 81 with drawing, this resetting means 9 is located at little runner 22 1 sides, and it has two holders 13,14 and stay cord 95, one of them holder 13 is by adjusting bolt 94 interlockings one U type frame 93, another holder 14 is connected with movable pulley 92 by elastic parts 91, this stay cord 95 is walked around movable pulley 92, and the one end is fixedlyed connected with U type frame 93, and the other end is fixedlyed connected with little runner 22.The resetting means of this magnetic control weight puller system is realized resetting of fitness equipment by the contraction of its elastic parts.All the other labels schematically as follows among Fig. 2: 1-pedestal, 11-support, 12-support, 111-bearing fixing lid, 112-screw, 4-axostylus axostyle, 6-pulley assembly, 61 pulleys, 62-fixed pulley, 82-fastener.

In practice, thisly simple pass through method that elastic parts realizes that fitness equipment resets also tool is in certain drawback, 1), when fitness equipment resets outstanding behaviours the following aspects:, stay cord is comparatively lax, comes off from pulley easily; 2), move maximal end point to and stop after, the pull-back forces of stay cord is too little, makes the sporter produce sense of discomfort; 3), perform physical exercise with slower speed, the pulling force of stay cord is too small, does not reach train on.

Because above several shortcomings make existing magnetic control system can't be used on the various training airplanes, have limited the development of sport and body-building device greatly.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming that existing magnetic control system can't be applied to the technology on the training airplane, and a kind of magnetic control multifunctional trainer is provided.

The technical scheme that its technical problem that solves the utility model adopts is as follows: magnetic control multifunctional trainer, its composition comprises: frame, assembly pulley, walk around the main stay cord of assembly pulley, it is characterized in that also including the magnetic control puller system, main stay cord withdrawing device, and brace with three links, the end of main stay cord is fixedlyed connected with brace first link, described magnetic control puller system mainly includes magnetic control wheel and tension thereof, belt pulley by the coaxial bearing connection, great wheel, little runner, and resetting means, described magnetic control wheel is coaxially connected with a belt pulley, this belt pulley is by belt and belt pulley socket, be wound with wiring on the described great wheel, one end and the great wheel of this wiring are fixed, and the other end is fixedlyed connected with second link of brace; The composition of described main stay cord withdrawing device includes one group of fixed pulley, walks around the pull back rope and the balancing weight of this group fixed pulley, a described end of pulling back rope is connected with balancing weight, the other end is fixedlyed connected with the 3rd link of brace, described wiring, pull back the rope identical to the force direction of brace, opposite with main stay cord to the force direction of brace.

The beneficial effects of the utility model are as follows: this training airplane has main stay cord withdrawing device, it realizes pulling back to training airplane master stay cord by balancing weight, stable, lasting characteristic that the pull-back forces that balancing weight provides has, can make main stay cord remain tight state, eliminate the possibility that stay cord comes off from pulley; When the sporter used this training airplane, after moving maximal end point to and stopping, main stay cord still had certain pull-back forces, strengthen train on, the sporter can not produce sense of discomfort yet, and can be by adjusting the weight of balancing weight, regulate static pulling force size, adapt to individual's exercise custom and requirement; When the sporter performed physical exercise with slower speed, the pulling force of main stay cord can be therefore and not too small, so can reach corresponding train on fully, this training airplane is fit to the each age group crowd and performs physical exercise, and advantage is remarkable.
