Abstract
The utility model discloses a Magdeburg principle type exerciser of arm tension and clamping force, comprising a left handle (1) and a right handle (2). The inner sides of the left and the right handles (1, 2) are respectively connected to a left piston rod (3) and a right piston rod (4). The inner ends of the left and the right piston rods (3, 4) are respectively connected to a left piston (5) and a right piston (6), which are inserted into the same piston cylinder (7). A space of 10cm is remained between the opposite walls of the left and the right pistons (5, 6). The Magdeburg principle type exerciser can not only build the outward tension of two arms, but also build the clamping force of two arms. The Magdeburg principle type exerciser is simple in structure, small in volume, convenient in carrying and easy in use.
Description
Technical field
The utility model relates to a kind of improvement of chest-developer, specifically a kind of horse Debao principle formula arm pulling force and folder strength exerciser.
Background technology
Connect among the sportsman at physical education or instruction, also or during health care takes exercise, the exercise of arm strength is important one.Arm strength is tempered the normal chest-developer that adopts, and the bulky spring and the handle that generally comprise tight winding constitute, and handle is fixed on the two ends of bulky spring, and when tempering arm strength, two hands are held handle respectively, firmly is pulled outwardly, thereby reaches the purpose of tempering arm strength.The deficiency of this chest-developer is: have only and temper the outside function of two arms, can not temper the folder power of two arms, and volume big, be not easy to carry, use inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of outside pulling force that can temper two arms, can also temper the inside folder power of two arms, and simple in structure, volume is little, be easy to carry, horse Debao principle formula arm pulling force and folder strength exerciser easy to use.
For reaching above purpose, the technical scheme that the utility model adopted is: this horse Debao principle formula arm pulling force and folder strength exerciser, constitute by the left hand and right hand handle, it is characterized in that: connect left and right piston rod respectively in the inboard of left hand and right hand handle, left and right piston the inner of left and right piston rod difference is fixedly connected, left and right piston inserts in the same piston cylinder, leaves the space of 10cm between the relative wall of left and right piston.
The utility model is also implemented by following measure: the middle part at piston cylinder is provided with pressure vacuum gauge, and the pressure test pipe of pressure vacuum gauge inserts in the space between the relative wall of left and right piston, and is attached thereto logical.
When using the utility model, when left hand and right hand respectively hand take left hand and right hand when being pulled outwardly, left and right piston outwards moves, because the space between the left and right piston seals, so the atmospheric density between the left and right piston reduces, the pressure indicated value of pressure vacuum gauge reduces, according to horse Debao hemisphere principle, until draw motionless till, this moment, the reading on the pressure vacuum gauge was outer arm strength of drawing; When left hand and right hand difference hand is taken left hand and right hand inside folder, left and right piston inwardly pushes away mutually, because the space between the left and right piston seals, so air pressurized between the left and right piston, density increases, the pressure indicated value of pressure vacuum gauge increases, till folder is motionless, and the arm strength of folder in the reading on the pressure vacuum gauge is at this moment.
The beneficial effects of the utility model are: temper the chest-developer that uses with present athletic training, match or health care and compare, can not only temper the outside pulling force of two arms, can also temper the inside folder power of two arms, and simple in structure, volume is little, be easy to carry, easy to use.
Description of drawings
Fig. 1 is a structure front-view schematic diagram of the present utility model.
Fig. 2 is that axis of no-feathering of the present utility model is to office's cross-sectional schematic.
Among the figure: 1, left hand handle; 2, right handgrip; 3, left piston bar; 4, right piston rod; 5, left piston; 6, right piston; 7, piston cylinder; 8, pressure vacuum gauge.
The specific embodiment
Make the utility model with reference to Fig. 1, Fig. 2.This horse Debao principle formula arm pulling force and folder strength exerciser, constitute 1,2 by left hand and right hand, it is characterized in that: 1,2 inboard is connected left and right piston rod 3,4 respectively in left hand and right hand, left and right piston 5,6 the inner of left and right piston rod 3,4 difference is fixedly connected, left and right piston 5,6 inserts in the same piston cylinder 7, leaves the space of 10cm between left and right piston 5,6 relative walls.
As further improvement of the utility model, be provided with pressure vacuum gauge 8 at the middle part of piston cylinder 7, the pressure test pipe of pressure vacuum gauge 8 inserts in the space between left and right piston 5, the 6 relative walls, and is attached thereto logical, simultaneously, prevent that also left and right piston 5,6 from moving to an end of piston cylinder 7.
When using the utility model, when left hand and right hand when hand takes left hand and right hand to be pulled outwardly 1,2 respectively, left and right piston 5,6 outwards moves, because the space between the left and right piston 5,6 seals, so the atmospheric density between the left and right piston 5,6 reduces, the pressure indicated value of pressure vacuum gauge 8 reduces, according to horse Debao hemisphere principle, until draw motionless till, this moment, the reading on the pressure vacuum gauge 8 was outer arm strength of drawing; When left hand and right hand difference hand takes left hand and right hand inwardly to press from both sides 1,2, left and right piston 5,6 inwardly pushes away mutually, because the space between the left and right piston 5,6 seals, so air pressurized between the left and right piston 5,6, density increases, the pressure indicated value of pressure vacuum gauge 8 increases, till folder is motionless, and the arm strength of folder in the reading on the pressure vacuum gauge 8 is at this moment.
Claims (2)
- Horse Debao principle formula arm pulling force with the folder strength exerciser, by left hand and right hand (1,2) are constituted, it is characterized in that: the inboard of (1,2) is connected left and right piston rod (3,4) respectively in left hand and right hand, the fixedly connected respectively left and right piston (5,6) of in the inner of left and right piston rod (3,4), left and right piston (5,6) inserts in the same piston cylinder (7), leaves the space of 10cm relatively between the wall at left and right piston (5,6).
- 2. horse according to claim 1 Debao principle formula arm pulling force and folder strength exerciser, it is characterized in that being provided with pressure vacuum gauge (8) at the middle part of piston cylinder (7), the pressure test pipe of pressure vacuum gauge (8) inserts left and right piston (5,6) relatively in the space between the wall.
