Abstract
The invention discloses a kind of muscle-type automatic door closer, it comprises locator that is installed on the doorframe and the stressed seat that is installed on the door leaf; The rotating shaft that horizontally rotates is installed on the locator, connects a horizon bar in the rotating shaft, the other end of horizon bar is provided with rotating cylinder, and rotating cylinder inserts on the axle of stressed seat; Hang with two extension springs in the rotating shaft, an extension spring tension is on locator, and another root extension spring tension is on horizon bar.The present invention has realized the purpose of closing the door automatically.The installation site of stressed seat is far away apart from the horizontal level of door-hinge, makes power distance at closing time bigger, thereby door closer of the present invention also can be used for some bigger doors.
Description
Technical field
The present invention relates to the door in house.
Background technology
Existing house door all is made up of doorframe, door leaf and door.All be by human hand push door at closing time, very inconvenient.Especially in public, the switch of door is frequent, this often occurs and closes the door and the situation of not closing the door, and brings inconvenience for people's live and work.In order to realize closing the door automatically, also can hang over a spring on the door leaf, but like this, not only damage door leaf but also not attractive in appearance, bigger at the noise that produces at closing time.Door closer in the market is various, and pluses and minuses are all respectively arranged, and door check of the present invention is different with existing door closer structure on the market.
Summary of the invention
The purpose of this invention is to provide a kind of muscle-type automatic door closer.
The structure of muscle-type automatic door closer of the present invention is: comprise locator that is installed on the doorframe and the stressed seat that is installed on the door leaf; The rotating shaft that horizontally rotates is installed on the locator, connects a horizon bar in the rotating shaft, the other end of horizon bar is provided with rotating cylinder, and rotating cylinder inserts on the axle of stressed seat; Hang with two extension springs in the rotating shaft, an extension spring tension is on locator, and another root extension spring tension is on horizon bar.
Spring is elongated when opening the door, and door is closed automatically in the restorable process of spring.
Advantage of the present invention is: realized the purpose of closing the door automatically.The installation site of stressed seat is far away apart from the horizontal level of door-hinge, makes power distance at closing time bigger, thereby door closer of the present invention also can be used for some bigger doors.
