Problems solved by technology

But the function of above-mentioned body-building equipment is relatively single, can not comprehensively and comprehensively exercise human upper limbs, this just makes many body-building enthusiasts need to buy multiple pieces of body-building equipment
In this way, on the one hand, the consumption cost of fitness enthusiasts is increased; on the other hand, because different parts of the human body are exercised separately through different fitness equipment, different parts of the human body cannot be exercised cooperatively, and the exercise intensity of each part is different. lead to poor fitness
[0003] Chinese utility model patent 91209488.5 discloses a screw-in torque device, which relies on both hands to hold the torque amplifier tightly, and twists in the opposite direction by overcoming the resistance of the spring to exercise the grasping force of human fingers, the twisting force of the wrist and The arm strength of the upper limbs, but its torque can only be adjusted by the angle of rotation, the range is small, and the strength is difficult to grasp. For beginners, too much force is easy to sprain, and too little force will not achieve the purpose of exercise. Empowering people to exercise step-by-step
[0004] Chinese utility model patent 201320194701.4 discloses a multifunctional arm-wrist trainer, the torque of which can only be adjusted by the relative rotation angle of both hands, and the structure is complex, which increases the number of failure points

Embodiment 1

[0035] Such as figure 1 and figure 2 As shown, the present invention installs the universal bearing 10 at the two ends of the mandrel 1, and the grip wheel 3 is installed on the universal bearing 10, and three snail springs 4 are arranged in the grip wheel 3, and the inner ends of each snail spring 4 are The connecting mandrel 1 and the outer end are provided with inserting handles 5; the grip wheel 3 is provided with a slot 6, the inserting handle 5 is inserted in the slot 6, and the inner wall of the slot 6 is processed with internal threads, and equipped with Bolt 7. An annular groove 16 is also provided in the grip wheel 3, and the outer ring of the snail spring 4 is clamped in the groove 16, so that the axial relative fixing of the snail spring 4 in the grip wheel 3 can be realized. A helical spring 2 is set on the mandrel 1 between the grip wheels 3, and the two ends of the helical spring 2 are connected to the grip wheels 3 on their respective sides, so that the tors...

Embodiment 2

[0042] The difference between this embodiment and the first embodiment lies in that the number of the control mechanism and the number of volute springs 4 used to control the socket handle 5 are different. Such as image 3Shown, present embodiment is provided with annular chute 14 in grip wheel 3, and the notch of annular chute 14 can switch, and slide block 15 is installed in the annular chute 14, and the other end of slide block 15 is fixed socket handle 5. When it is necessary to increase the torque, the notch is closed, and the slider 15 is clamped, so that the outer end of the volute spring 4 is relatively fixed with the grip wheel 3; when the torsion needs to be reduced, the notch is opened, and the slider 15 can freely slide in the annular chute 14, and release the restriction of the notch to the outer end of the spiral spring 4, so that the insertion handle 5 can slide freely in the grip wheel 3. Reciprocating in this way can also realize the adjustment of the number ...

Abstract

The invention discloses a method for adjusting the torsion of an arm-wrist exercise device and a torsion-adjustable arm-wrist exercise device, which belong to the field of fitness equipment. For the above snail spring, the inner end of the snail spring is connected to the mandrel, and the outer end is connected to the control mechanism; when the torque is increased, the control mechanism makes the outer end of the snail spring relatively fixed with the grip wheel; when the torsion is reduced, the control mechanism makes The outer end of the spiral spring is in a free state. The invention can flexibly increase or decrease the number of volute springs in the working state to adjust the torsion of the fitness equipment, so that the bodybuilder can complete step-by-step exercise.

Description

technical field [0001] The invention belongs to the field of fitness equipment, and in particular relates to a method for adjusting the torque of an arm-wrist fitness device and a torsion-adjustable arm-wrist fitness device. Background technique [0002] In recent years, along with the strengthening of people's awareness of fitness and physical fitness, various fitness equipment has emerged as the times require, including arm strength devices, wrist strength devices and dumbbells for exercising the upper limbs of the human body. But the function of above-mentioned fitness equipment is more single, can not comprehensively, comprehensively exercise human body upper limbs, this just makes many fitness enthusiasts need to buy multiple pieces of fitness equipment. In this way, on the one hand, the consumption cost of fitness enthusiasts is increased; on the other hand, because different parts of the human body are exercised separately through different fitness equipment, differen...
