Abstract
The present invention realizes fast opening and slow closing of door with energy accumulating spring and simple non-return valve to produce damping. The moving parts are hidden inside tube and this makes it beautiful. In addition, when the small ring on one end of the pull rope is taken off from the small shaft, the door will restore its manual opening and closing state optionally. Therefore, the present invention has wide market foreground.
Description
Patent of the present invention belongs to the architectural decoration accessory.
The door of building units such as the air-conditioned room in the building, conference room, rest room, kitchen is opened the back as if closing automatically and is bound to be subjected to people's welcome, can realize this goal with the mode that installs automatic door closer additional.Existing automatic door closer, high-grade employing hydraulic structure, higher though performance is good because of price, be difficult to large-scale popularization; The middle-grade mechanical external hanging type of general employing, plug-in portion size is bigger, and is attractive in appearance inadequately, breaks down easily again, also do not see widely-used.
It is the quick-opening slow-closing type automatic door closer of energy storage unit with built-in extension spring that patent of the present invention is intended to provide a kind of.
The operating principle of patent of the present invention is, with built-in tension spring, and left end form the air chamber of a base closed and right-hand member to be the automatic door closer of open air chamber be installed in the doorframe inside front, independent bearing is installed in an inside front, and the metal ring of door closer stay cord one end is enclosed within bearing makes progress on the little axle that the Shen goes out.When opening the door, the moving fortune of the rotation of door becomes the Shen of drawing of spring to move by the role transformation of stay cord and pulley.After external force disappeared, extension spring began to shrink, and door is subjected to the traction of stay cord and closes automatically.Opening the door and closing in the process of door, because the effect of plain type one way valve makes the target that changes down the pass soon be achieved in the valve seat of door closer stage casing.
Described in detail below in conjunction with the structure and the course of work of accompanying drawing patent of the present invention.
Fig. 1 installs outside drawing for patent of the present invention.
Fig. 2 is the structure chart of patent main body of the present invention.
Fig. 3 is a patent A-A sectional drawing of the present invention.
Among the figure, 1-left socle, 2-O shape circle, 3-extension spring, 4-valve seat, 5-bearing pin, 6-small pressure spring, 7-sealing ring, 8-steel ball, 9-stack shell, 10-stay cord, 11-right support, the little pin of 12-(three places), 13-pulley (two places), the little ring of 14-, 15-bearing.
As seen from the figure, when door was opened, bearing (15) drove the effect pulling valve seat (4) of little ring (14) by stay cord (10) and pulley (13) and moves to right, and the steel ball (8) in valve seat this moment (4) is backed down by air-flow, and the Shi Buhui that therefore opens the door feels to have much resistances.After external force disappeared, extension spring (3) began to shrink, because air communication is when crossing the aperture of valve seat (4), what be subjected to small pressure spring (6) and steel ball (8) stops that resistance is bigger, so the process of closing the door is slower, just in time met people's slow requirement of closing the door.
Patent of the present invention is owing to adopted spring for accumulating energy and the principle of plain type one way valve generation damping, just the method with less expensive makes that changing down the pass function soon is achieved, and movement parts is ensconced in the stack shell that very easily beautifies basically, comparison operators is built the requirement of building decoration jointly, in addition, as long as the little axle of the little ring (14) on stay cord (10) termination from bearing (15) top taken off, door has just recovered the state of manual switching, thereby has increased user's selectivity.Based on above advantage, patent of the present invention should have vast market prospect.
