Abstract
The utility model provides a dynamometer which is characterized that a cylinder body is included, an air-pressure valve is arranged at the middle part of the cylinder body, a pair of opposite pistons is arranged in the cylinder body, an outward connecting rod is fixed on each piston, a sliding pull-shaft is fixed at the end part of each connecting rod, fixed pull-shafts are fixed at the two ends of the cylinder body, and the sliding pull-shafts and the fixed pull-shafts form handles. The grip device has the advantages that the needed grip strength can be adjusted according to the requirements of different exerciser, the grip device can be easily used for exercise by the user with more or less strength, and the exercise effect is good.
Description
(1) technical field
The utility model belongs to the sport and body-building instrument, particularly a kind of spring-grip.
(2) background technology
Existing spring-grip mostly is made of handle and spring, and the open angle of the size of its spring force and handle can not be adjusted, and can't adapt to different body builders' needs, is difficult to the train on that reaches best.
(3) summary of the invention
The utility model provides a kind of spring-grip that can adjust required grip size according to different body builders' needs in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Spring-grip of the present utility model, its special character is: comprise cylinder body, be provided with air pressure valve in the middle of the cylinder body, be provided with the opposite piston of a pair of direction in the cylinder body, be fixed with outside connecting rod on each piston, the end of connecting rod is fixed with the slip pulling shaft, and the cylinder body two ends are fixed with fixedly pulling shaft, the slip pulling shaft and fixedly pulling shaft form handle.
Spring-grip of the present utility model, the structure of being made up of cylinder body, piston, connecting rod, air pressure valve is some covers, the cylinder body of each cover is fixed as one side by side, the slip pulling shaft that is positioned at cylinder body one end is one and is connected to a fixed with all connecting rods of this end, and the fixedly pulling shaft that is positioned at cylinder body one end is one and is connected to a fixed with two cylinder bodies in the outside of this end.
Spring-grip of the present utility model is shaped as circular arc.
The beneficial effects of the utility model are, can adjust required grip size according to different body builders' needs, and no matter the strength size can both use this spring-grip to perform physical exercise very easily, and train on is good.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 cylinder body, 2 pistons, 3 connecting rods, 4 slip pulling shafts, 5 air pressure valves, 6 fixing pulling shafts.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Spring-grip of the present utility model, comprise cylinder body 1, be provided with air pressure valve 5 in the middle of the cylinder body, be provided with the opposite piston of a pair of direction 2 in the cylinder body, be fixed with outside connecting rod 3 on each piston, the end of connecting rod is fixed with slip pulling shaft 4, and the cylinder body two ends are fixed with fixedly pulling shaft 6, the slip pulling shaft and fixedly pulling shaft form handle.The structure of being made up of cylinder body, piston, connecting rod, air pressure valve is 3 covers, the cylinder body of each cover is fixed as one side by side, the slip pulling shaft that is positioned at cylinder body one end is one and is connected to a fixed with all connecting rods of this end, and the fixedly pulling shaft that is positioned at cylinder body one end is one and is connected to a fixed with two cylinder bodies in the outside of this end.
Spring-grip of the present utility model, can be made into the two-way arc spring-grip of air pressure, also can make straight, there are three kinds of different pulling force to open or close by the air pressure valve in the middle of each cylinder body, make its cylinder body whether have the effect of pulling force, the number difference by valve open adapts to different body builders.The both hands that can realize the people carry out the grip exercise simultaneously, and pulling force is adjustable, and use angle is comfortable.Can realize vacuum in the cylinder, venting speed or intake velocity by adjusting air pressure valve.Handle by the slip pulling shaft and fixedly pulling shaft form, fixedly pulling shaft is fixed on the cylinder body by support, the slip pulling shaft is fixed on the connecting rod by support.Be preferably on the support of fixing pulling shaft chute is set, slidably reciprocate for the slip pulling shaft.Cylinder body, piston, connecting rod are made by anti-rust metal.
