Abstract

The utility model relates to an electro-magnetic pulling force exerciser, which belongs to the field of movement training instruments. The utility model comprises a frame, right and left handles, right and left pull ropes, right and left electrical machines and control units. One end of the right pull rope and one end of the left pull rope are respectively connected with the right and left handles, and the other end of the right pull rope and the other end of the left pull rope are respectively connected with the shafts of the right and left electrical machines. The electro-magnetic pulling force exerciser of the utility model can singly distinguish and regulate the training intensity of the right or the left hand. The utility model has the advantages of simple structure, low cost, long service life, and high quality.

Description

Electro-magnetic pulling force exerciser

The utility model relates to a kind of electromagnetic type tension trainer, belongs to training apparatus field.

Once there was a kind of sports-training apparatus to sell on the American market, it comprises framework, about the handle, left and right sides stay cord, about two or a flexible member, one end of left and right sides stay cord respectively with about shake hands to link to each other, the other end of left and right sides stay cord is connected with above-mentioned flexible member respectively, comply with the effect such as the flexible member of spring, the user can spur handle and train the health of oneself, and this training aids is called as spring reset formula chest expander, its shortcoming is: right-hand man's training strength can not be distinguished separately, regulate, in use, the spring easy fracture, clutch wherein is also easy to wear.

The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of right-hand man's training strength can distinguish separately, regulate, and is simple in structure, cheap, the electromagnetic type tension trainer of long service life.

The utility model electromagnetic type tension trainer comprises framework, about handle, left and right sides stay cord, about two motors and controller, an end of left and right sides stay cord respectively with about shake hands to link to each other, the other end of left and right sides stay cord respectively with spool being connected of left and right sides motor.

The training strength that the utility model electromagnetic type tension trainer can be distinguished separately, regulate the right-hand man, simple in structure, cheap, long service life provides certain guarantee for improving training quality.

For introducing the utility model in detail, describe below in conjunction with accompanying drawing:

Fig. 1 is the stereochemical structure sketch of electromagnetic type tension trainer of the present utility model;

Fig. 2 is the circuit block diagram of the controller in the training aids of the present utility model.

The electromagnetic type tension trainer of partly cutting open has been shown among Fig. 1, comprise framework 2, about shake hands 3,5, left and right sides stay cord 4,6, about two motor 10,10 ' (on figure, not illustrating) and controller 9, framework 2 sits supporting plate for sleeping in 13 by the trainer and installing rack 14 is formed, an end of left and right sides stay cord 4,6 respectively with about shake hands 3,5 to link to each other, the other end of left and right sides stay cord 4,6 respectively with left and right sides motor 10,10 ' axle 11,11 ' (on figure, not illustrating) be connected.

For safety and reason such as attractive in appearance, generally, also have a display 8 on the tank shell 7 at motor 10,10 ' and tank shell 7 of outer cup of controller 9, show merit and other data that need express of right-hand man's pulling force and work respectively.

Left and right sides stay cord 4,6 can directly be wrapped in respectively left and right sides motor 10,10 ' outrigger shaft 11,11 ' on, also can by one around the wheel (on figure, not illustrating) connect, stay cord be wrapped in around the wheel on, around the wheel be connected with motor shaft again.Stay cord 4,6 stride across the

back gear

1,1 that is positioned on the framework 2 ' with about shake hands 3,5 to be connected.

Electromagnetic type tension trainer of the present utility model has been used the principle of electromagnetic conversion, the double grading that has motor and generator according to direct current generator, input at motor adds a voltage, motor is in state of motor, the voltage that applies is removed at the motor two ends, and motor is applied external force rotates motor, at this moment, motor has the characteristic of generator again, motor is in the duty of generator again, the characteristic of this electromagnetic conversion is used on the tension trainer, embodies its electromagnetism reset feature, brings its advantage and good effect.

Wherein the controller of Ying Yonging is very important concerning electromagnetic type tension trainer of the present utility model, and two controllers 9 can be arranged, they respectively with motor 10,10 ' be connected; Controller 9 also can be one, and promptly controller is two road integrative-structures, two tunnel in the controller 9 respectively with motor 10,10 ' be connected, and control the work of two motors respectively.

When training, the people crouches on the supporting plate of framework, by handle pulling stay cord, be wrapped in the stay cord pulling motor on the motor shaft, at this moment, motor is in the duty of generator, generator applies resistance to the trainer, after loosing one's grip, controller action, the duty of conversion motor, make motor be in state of motor, the pulling stay cord resets handle, back and forth changes like this.

Certain variation takes place in the frame structure form, can make the exercising device of similar applications.

Referring to Fig. 2, the working method of electromagnetic type tension trainer of the present utility model is as follows: connect power supply, trigger reset in the controller is to the motor duty, the display automatic clear, motor rotates and drives the stay cord tension, motor will transship, electric current increases in the motor, sampling voltage in the controller will be above preset value, comparator output triggering signal changes flip-flop states through shaping, this triggering signal is through the analog line driver I, II disconnects power electronic switching (1), power electronic switching (2) is connected to enter automatically and is drawn wait state, motor enters the generator state, pulling this moment handle, the rope pulling is rotated motor shaft, motor applies resistance as generator to the trainer, the voltage of motor output is through sampling and through voltage--after the frequency inverted, obtain power signal after multiplying each other with displacement signal, through stored count, driving display directly shows the merit of being done, when the time that handle stops to surpass the time of presetting, the state turnover of trigger, the triggering signal of output is through the analog line driver I, II disconnects power electronic switching (2), power electronic switching (1) is connected, and motor is got back to the motor duty, drives stay cord and resets, enter again after the overload and draw wait state, so repeatedly.

Between trigger and analog line driver I, II, be connected to the photoelectricity isolated tube, shown in Figure 2 is a theory diagram, this professional those of ordinary skill can select for use suitable components and parts to process the controller of the job requirement that meets electromagnetic type tension trainer of the present utility model on this basis fully.
