Description

Track-type automatic door closer

Technical field

The utility model 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 utility model is different with existing door closer structure on the market.

Summary of the invention

The purpose of this utility model provides a kind of track-type automatic door closer.

The structure of the utility model track-type automatic door closer is: comprise being installed in to have fan-shaped track pedestal on the doorframe and be installed in stressed seat on the door leaf; Be processed with deep-slotted chip breaker on the fan-shaped track pedestal, be processed with axis hole on the stressed seat, also comprise a bending axle, bending axle one end inserts deep-slotted chip breaker, and the other end inserts axis hole, and the bending axle is gone up and hung tension spring tension on the track pedestal.

For the bending axle is slided flexibly, on the bending axle bearing is housed.

During automatic door work, spring is elongated, and when the people unclamped hand, door was closed under the effect of spring automatically.When needs opened wide door, bearing was absorbed in an end of track, and door will be fixed.When making bearing skid off an end of track with the hand push door at closing time, will shut automatically with the back door.

The utility model has the advantages that: track-type automatic door closer has not only been realized closing the door automatically, can not keep the shortcoming of opening wide automatically but also overcome automatic door in the past.Simple in structure, the low cost of manufacture of track-type automatic door closer is easy to promote the use of.

Marginal data: 1---door leaf, 2---doorframe, 3 track pedestals, 4---the bending axle, 5---deep-slotted chip breaker, 6---bearing, 7---spring, 8---stressed seat.

The specific embodiment

As shown in the figure, the utility model comprises being installed in to have fan-shaped track pedestal 3 and the stressed seat 8 that is installed on the door leaf 1 on the doorframe 2.Be processed with deep-slotted chip breaker 5 on the track pedestal 3, be processed with axis hole on the stressed seat 8, bending axle one end inserts deep-slotted chip breaker 5, and the other end inserts axis hole, hangs a tension spring 7 tensions on the bending axle 4 on track pedestal 3.For bending axle 4 is slided flexibly, on the bending axle 4 bearing 6 is housed.

During automatic door work, spring 7 is elongated, and when the people unclamped hand, door was closed under the effect of spring 7 automatically.When needs opened wide door, bearing 6 was absorbed in an end of deep-slotted chip breaker 5, and door will be fixed.When making bearing 6 skid off an end of deep-slotted chip breaker 5 with the hand push door at closing time, will shut automatically with the back door.
