Abstract
A tension fine-adjustable spring exerciser comprises a pair of handles and a group of tension springs. The group of tension springs consists of tension springs with different stiffness coefficients. The tension fine-adjustable spring exerciser has the advantages that as stiffness coefficients of the tension springs of the spring exerciser are different, different tension springs with different stiffness coefficients can be selected according to needs of body-building persons, and then the tension fine-adjustable spring exerciser can realize tension fine-adjustment, and bring convenience for the body-building persons.
Description
Technical field
The utility model relates to the body-building apparatus field.Relate in particular to the fine-tuning chest expander of a kind of pulling force.
Background technology
Existing chest expander is formed by a pair of handle and 4-5 root tension spring, and 4-5 root tension spring two ends hang on the hook ring of a pair of handle by hook.Hang over the pulling force that quantity on a pair of handle is regulated chest expander by regulating tension spring during use.1 of every increase or reduce by 1 tension spring and all can increase or reduce 1/4 or 1/5 pulling force, the pulling force amplitude of accommodation span of chest expander is excessive, can not finely tune neatly, has caused a lot of inconvenience to the user.
The utility model content
The purpose of this utility model is all identical at the pulling force of existing 5 tension springs of chest expander (also having 4), 1 of every increase or reduce by 1 tension spring and all can increase or reduce 1/5 pulling force, the pulling force amplitude that increases or reduce is excessive, the deficiency that pulling force can not be finely tuned, and provide a kind of pulling force fine-tuning chest expander.
The chest expander that a kind of pulling force of the utility model is fine-tuning comprises a pair of handle and one group of tension spring, and one group of tension spring is made up of the different tension spring of stiffness factor.
One group of tension spring is 3 tension springs; 3 tension springs are made up of 3 kinds of different tension springs of stiffness factor.
One group of tension spring is 4 tension springs; 4 tension springs are made up of 4 kinds of different tension springs of stiffness factor; Or 4 tension springs are made up of 3 kinds of different tension springs of stiffness factor; Or 4 tension springs are made up of 2 kinds of different tension springs of stiffness factor;
One group of tension spring is 5 tension springs; 5 tension springs are made up of 5 kinds of different tension springs of stiffness factor; Or 5 tension springs are made up of 4 kinds of different tension springs of stiffness factor; Or 5 tension springs are made up of 3 kinds of different tension springs of stiffness factor; Or 5 tension springs are made up of 2 kinds of different tension springs of stiffness factor.
The utility model has the advantages that: because the stiffness factor of each root tension spring of chest expander is inequality, can select the different tension spring of various stiffness factors for use, thereby can realize the pulling force fine setting, bring convenience to the body builder according to need body builder needs.

Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Embodiment 1: the utility model comprises that a pair of handle 1 and 2,5 tension springs 2 of 5 tension springs all select the tension spring of different stiffness factors for use.The diameter difference of tension spring and tension spring material difference all can make the stiffness factor difference of tension spring.
In the embodiment 2:5 root tension spring, select the identical tension spring of stiffness factor for use for 4, select stiffness factor and 4 tension springs that stiffness factor is inequality for use for 1 in addition.
In the embodiment 3:5 root tension spring, select the identical tension spring of stiffness factor for use for 3, in addition select stiffness factor and above-mentioned 3 tension springs that stiffness factor is inequality for use for 2, and this other 2 also select stiffness factor tension spring inequality for use.
In the embodiment 4:5 root tension spring, select the identical tension spring of stiffness factor for use for 2, in addition select stiffness factor and above-mentioned 2 tension springs that stiffness factor is inequality for use for 3, and other 3 also select stiffness factor tension spring inequality for use.
In the embodiment 5:5 root tension spring, select the identical tension spring of stiffness factor for use for 2, in addition select stiffness factor and above-mentioned 2 tension springs that stiffness factor is inequality for use for 3, and this other 3 also select the identical tension spring of stiffness factor for use.
In the embodiment 6:5 root tension spring, select the identical tension spring of stiffness factor for use for 2, select stiffness factor and above-mentioned 2 tension springs that stiffness factor is inequality for use for 2 in addition, and this in addition 2 also select the identical tension spring of stiffness factor for use, surplus 1 select the tension spring all inequality for use with other tension spring stiffness factor.
