Abstract
The utility model discloses an extension gas spring, consisting of an external cylinder, an internal cylinder, a piston rod, a piston and a lip type seal ring. An external gas chamber is formed between the external cylinder and the internal cylinder, and an internal gas chamber is formed inside the internal cylinder. A throttle is arranged at the left end of the external and internal cylinder, and a pressure stabilizing hole is arranged at the right end of the internal cylinder. The piston and the piston rod are arranged in the internal cylinder, and the lip type seal ring seals the piston rod. The utility model has advantages of convenient use, easy manufacture, low cost and installation inside the door and window. When the utility model is manufactured, an inflation head is arranged at one end of the piston rod and connected with a gas source, and then inert gas can be inflated into a gas chamber via the lip type seal ring; the throttle can control the amount and velocity of gas flow and control the motion speed of the piston rod.
Description
Technical field:
The utility model belongs to a kind of gas spring.
Background technique:
Present air spring mostly is a compression type, in use can only be installed in the outside of equipment, and is so not only not attractive in appearance, and influences using effect sometimes.In addition, air spring also needs special device when inner inflatable, makes inconvenient.
Summary of the invention:
The purpose of this utility model is: a kind of stretching air spring is provided, and its using effect is good, makes easily, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it is by outer cylinder (1), inner cylinder tube (2), piston rod (3), piston (4), lip-type seal circle (5) is formed, air cavity (6) outside between outer cylinder (1), inner cylinder tube (2), forming, interior air cavity (7) is in inner cylinder tube (2), left end at outer cylinder (1) and inner cylinder tube (2) has throttle valve (8), right-hand member at inner cylinder tube (2) has pressure stable hole (9), piston (4) and piston rod (3) are contained in the inner cylinder tube (2), and lip-type seal circle (5) seals up piston rod (3).
The utility model compared with prior art has easy to usely, makes easily, and cost is low, can be installed in advantages such as door and window inside.During making, be contained in an end of piston rod with a pneumatic head, connect source of the gas, inert gas just can charge into air cavity from the lip-type seal circle; The flow and the flow velocity of throttle valve may command air-flow, thereby the movement velocity of control piston bar.
Description of drawings:
Accompanying drawing 1 is a structure principle chart of the present utility model.
Embodiment:
Embodiment of the present utility model: piston (4) and piston rod (3) are contained in the inner cylinder tube (2), form outer air cavity (6) between outer cylinder (1) and the inner cylinder tube (2), interior air cavity (7) is in inner cylinder tube (2), left end at outer cylinder (1) and inner cylinder tube (2) is equipped with throttle valve (8), right-hand member at inner cylinder tube (2) has pressure stable hole (9), and lip-type seal circle (5) seals up piston rod (3).
Claims (1)
1, a kind of stretching air spring, it is by outer cylinder (1), inner cylinder tube (2), piston rod (3), piston (4), lip-type seal circle (5) is formed, it is characterized in that: air cavity (6) outside between outer cylinder (1), inner cylinder tube (2), forming, interior air cavity (7) is in inner cylinder tube (2), left end at outer cylinder (1) and inner cylinder tube (2) has throttle valve (8), right-hand member at inner cylinder tube (2) has pressure stable hole (9), and piston (4) and piston rod (3) are contained in the inner cylinder tube (2), and lip-type seal circle (5) seals up piston rod (3).
