Abstract
A pressure vessel having a container, a cover and a control device for closing and opening of the cover of the container, wherein the control device consists of at least two driving arms movably mounted on the cover. A knob is pivotally mounted on a central axis of the cover, and a rotary plate is co-axially fixed at a lower end of the knob. The rotary plate is rotatably movable together with the knob and particularly formed with at least two rotary drivers corresponding to engagement posts formed on driving arms. Jaws fixed at outer ends of the driving arms driven by the rotary drivers of the rotary plate are movable in a radial direction relative to the central axis of the cover between a locking position in which the cover is locked to the container and an unlocking position in which the cover can be removed from the container.
Claims6
A pressure vessel comprising a container (10), a cover (20) and a control device (30) for closing and opening the cover (20) of the container (10), wherein the control device (30) having:
- at least two driving arms (31) movably mounted on a body (21) of the cover (20), each driving arm (31) having an inner end formed with an engagement post (311) and an outer end securely connected to a jaw (313);
- a knob (32), which is pivotally mounted on a central axis of the cover (20) and defined with multiple assembly holes (321) in the lower end thereof, the assembly holes (321) corresponding to multiple assembly pins (330) fixed on the rotary plate (33);
- a rotary plate (33) co-axially fixed at a lower end of the knob (32) and rotatably moveable together with the knob (32), and formed with at least two rotary drivers (331) corresponding to the engagement posts (311);
- a fixed frame (36) mounted on the body (21) of the cover (20) above the driving arms (31) and the rotary plate (33), and defined with multiple arc slots (361) corresponding to the assembly pins (330);
- and
- multiple elastic elements (34) respectively provided between driving arms (31) and fixed frame (36) to assure retraction of the driving arms (31);
- whereby
- the jaws (313) fixed with the driving arms (31) driven by the rotary drivers (331) of the rotary plate (33) are movable in a radial direction relative to the central axis of the cover (20) by turning the knob (32) manually between a locking position in which the cover (20) is locked to the container (10) and an unlocking position in which the cover (20) can be removed from the container (10).
