Description
Technical field
Damping safety pulley weight, relates to body-building apparatus technical field.
Background technology
Take exercises, strengthening healthyly has become the general needs of existing social people.The chest expander of the body-building apparatus of prior art is the most generally sold for a long time and used chest expander to be still two ends always two handles, and centre is the form of several springs (or rubber band of high-tension) with hook.But such chest expander is large due to spring (or rubber band) elasticity, uses the control will depending on people during body-building completely, once strength is slightly inferior after pulling open, lose control of as easy as rolling off a log out of control, resilience once, encounters and cause danger on the face.
Summary of the invention
For overcoming the deficiency that prior art exists,
The object invention design of the application is a kind of easily to be controlled, safe and reliable chest expander.
The application adopts following technical scheme for achieving the above object:
1, damping safety pulley weight, comprising: oil cylinder cover 1, secondary oil cylinder 2, piston component 3, spring 4, piston rod 5, hook 6, bar side end cap 7, elementary oil cylinder 8, rodless side end cap 9;
It is characterized in that:
Piston component 3 comprises: piston tongue 3-1, return port 3-2, check-valves 3-3,
Elementary oil cylinder 8, secondary oil cylinder 2, piston component 3 is had in oil cylinder cover 1;
By piston tongue 3-1 separately, piston tongue 3-1 is connected side oil cylinder with piston rod 5 is elementary oil cylinder 8 for elementary oil cylinder 8 and secondary oil cylinder 2,
The oil cylinder that piston tongue 3-1 does not connect piston rod 5 side is secondary oil cylinder 2;
Piston rod 5 one end connects piston tongue 3-1, piston rod 5 other end coupling hook 6;

Piston rod 5 one end is at elementary oil cylinder 8, and the other end is passing bar side end cap 7 outside elementary oil cylinder 8;
Oil cylinder cover 1 is built with oil plant.(being mounted on by hook 6 during use is equipped with on the handle of hook, when body builder firmly pulls open, spring 4 is compacted, simultaneously oil plant, and body builder removes firmly, at spring 4 flexible effect lower piston assembly 3 to rodless side end cap 9 one lateral movement, oil plant in secondary oil cylinder 2 is extruded in elementary oil cylinder 8, because the oil plant be extruded has pressure, therefore substantially reduces the pulling force of spring, thus play chest expander can not resilience rapidly, avoid causing danger.Oil plant in oil cylinder cover 1 only flows between elementary oil cylinder 8 and secondary oil cylinder 2.)
2, damping safety pulley weight, is characterized in that: described piston tongue 3-1 has 8 ~ 12 return port 3-2.
3, described damping safety pulley weight, is characterized in that: described oil plant is machine oil.
4, described damping safety pulley weight, is characterized in that: described piston tongue 3-1 has 4 ~ 6 check-valves 3-3.(when making to pull open, resistance is less, when removing strength, during natural resilience, owing to having on the return port 3-2 of half, check-valves is housed, so the back-flow velocity of oil plant reduces, reaches the object of release resilience safety)
Beneficial effect
1, when body builder firmly pulls open, spring 4 is compacted, oil plant simultaneously, body builder removes firmly, at spring 4 flexible effect lower piston assembly 3 to rodless side end cap 9 one lateral movement, oil plant in secondary oil cylinder 2 is extruded in elementary oil cylinder 8, because the oil plant be extruded has pressure, therefore substantially reduce the pulling force of spring, thus play chest expander can not resilience rapidly, avoid causing danger, use safety.
