Abstract
The utility model relates to a non-step positioning, automatic, noiseless door closing device is a novel architectural hardware. The utility model is designed as an independent accessory of a door. Any doors can be provided with the utility model without any reconstruction. The non-step positioning, automatic, noiseless door closing device can cause the door to be closed automatically, slowly and noiselessly. Furthermore, when the door needs to keep opening, the user only needs to dial a positioning mechanism. Then the door can keep opening stably at any positions. The utility model collects three functions such as non-step positioning, automatism, and noiseless door closing as a whole body. The principle is advanced, and the structure is simple. The non-step positioning, automatic, noiseless door closing device can not only satisfy the requirement of hospitals, schools, hotels and advanced building facilities, but also can be quickly popularized to common companies and families. The working and living environment of people can become more civilized and exquisite.
Description
Can steplessly locate, automatic, noiseless door closer is a kind of novel architectural hardware.
Desirable door should be both to have opened conveniently, can automatic, mutingly close again, when needs open wide, also can open wide in the maintenance of arbitrary position stability.But up to now, also there is not a kind of product can make door have these functions on the market comprehensively.
Before decades, people have just designed door engines such as spring hinge, floor spring, most place then is that people simply nail on rubber or spring on door, yet these devices all can only make door closing rapidly, and people Chang Yin is too late to dodge and bumps pin, bumps hand.Sometimes even more serious accident takes place.Simultaneously, the scram of door and the impact sound that causes has caused new environment pollution again; These devices except that floor spring can door open 90 can locate when spending, and all powerless to the location of arbitrary open position, when people need keep door to open wide, have to go to stop with weights such as stooles, both inconvenient, uncivil again.
The present invention integrate can steplessly locate, automatically, noiseless three functions of closing the door, for people provide a kind of multiple functional, convenient and practical door closer, make people's work, living environment is civilization, graceful more.
The present invention is mainly by pull bar (1); Spacer (2); Cylinder body (3); Spring (4); One way valve (5); Piston (6); And hydraulic oil (7) forms, and pull bar (1) is contained in the hole of cylinder body (3) one ends and can axially reciprocating, and spring (4) is sleeved on pull bar (1) and is positioned on the end of cylinder body (3) oil pocket, has formed the door engine structure; Spacer (2) is contained in pull bar (1) and stretches on the outside end of cylinder body (3), and can go up at pull bar (1) and slide, and has constituted detent mechanism; The end that one way valve (5) and pull bar (1) are arranged in cylinder body (3) oil pocket one end connects and is installed in the hole of piston (6), and one way valve (5) maintains certain axial float in the hole of piston (6).On the end face of piston (6), have the unloading hole and the throttle orifice that communicate with the hole of adorning one way valve (5), add the hydraulic oil (7) that is full of cylinder body (3) cavity volume, formed the unidirectional speed limiting system of hydraulic pressure.
Operating principle of the present invention: door closer one end is contained on the doorframe, one is contained on the door, when opening the door, pull bar (1) is with stretching outdoors, traction one way valve (5) moves, one way valve (5) traction piston (6) again moves together, and at this moment unloading hole and throttle orifice all are in opening, and what the hydraulic oil (7) of the interior rod chamber of cylinder body (3) can be without hindrance freely goes into rodless cavity via two orifice flows.Meanwhile, spring (4) is compressed.After the external force that pushes removes, door is past swivel motion under spring (4) reset force effect, contract in the pull bar, promote one way valve (5), one way valve (5) blocks the off-load mouth earlier, promote piston (6) subsequently, at this moment, the hydraulic oil (7) of the interior rodless cavity of cylinder body (3) can only flow into rod chamber through throttle orifice, the speed that contracts in the pull bar (1) is subjected to the restriction of hydraulic oil flow velocity, make an energy slow thereby reached, merrily and lightheartedly, the purpose that noiseless is closed, when needs door during in a certain open position location, at first door is opened desired location, running fix sheet (2) makes it near cylinder body (3) end face then, remove the power of pushing, cylinder body (3) desire under the reset force effect of spring (4) continues motion, at this moment, spacer (2) produces beat and self-locking under the promotion of cylinder body (3) end face, thereby makes stable this open position that remains on of door.
The present invention utilizes fluid damping and speed limit, and utilize spring reset power to make the detent mechanism self-locking and locate, principle advanced person, simple in structure.
The present invention designs as a kind of separate accessories of door, and any Men Buxu transforms and all can install, and it can not only extensively replace traditional spring hinge, door engines such as floor spring.Better meet the demand of hospital, school, hotel and senior building facility.Simultaneously, also will spread to general unit and family rapidly, become the product of the indispensable indispensability of door.

Claims (1)
1, can steplessly locate, automatic, noiseless door closer: utilize fluid damping and speed limit, utilize spring reset power to make the spacer beat produce self-locking and locate, mainly by pull bar (1); Spacer (2); Cylinder body (3); Spring (4); One way valve (5); Piston (6); And hydraulic oil (7) forms, and it is characterized in that: pull bar (1) is contained in the hole of cylinder body (3) upper end, and can axially reciprocating, and spring (4) is sleeved on pull bar (1) and is positioned on the end of cylinder body (3) oil pocket, has formed the door engine structure; Spacer (2) is contained in pull bar (1) and stretches on the outside end of cylinder body (3), and can go up at pull bar (1) and slide, and has constituted detent mechanism; The end that one way valve (5) and pull bar (1) are arranged in cylinder body (3) oil pocket one end connects and is installed in the hole of piston (6), one way valve (5) maintains certain axial float in the hole of piston (6), on the end face of piston (6), have the unloading hole and the throttle orifice that communicate with the hole of adorning one way valve (5), add the hydraulic oil (7) that is full of cylinder body (3) cavity volume, formed the unidirectional speed limiting system of hydraulic pressure.
