Abstract
The invention discloses a clockwork-type door self-closing device which comprises a clockwork case fixed on a doorframe and a stress base fixed on a door leaf; a shaft core is arranged in the clockwork case, a clockwork spring is wound around the shaft core, one end of the clockwork spring is fixed, the other end thereof is connected with a sleeve after extending from the clockwork case, and the sleeve is sheathed on a shaft of the stress base. The invention solves the problem that a door needs to be closed but actually not. The clockwork-type door self-closing device of the invention is simple in structure, small in volume and easy in installation.
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 Clockwork-type door self-closing device.
The structure of Clockwork-type door self-closing device of the present invention is: it comprises clockwork case that is fixed on the doorframe and the stressed seat that is fixed on the door leaf; A core is installed in the clockwork case, is wound with a clockwork spring and an end on the core and fixes, the other end of clockwork spring stretches out the back from clockwork case and links to each other with sleeve, and jacket casing is on the axle of stressed seat.When opening the door, along with the motion of stressed seat, clockwork spring generation deformation, rotating cylinder rotates along with the motion of clockwork spring.
In order to reduce the friction of clockwork spring, locating shaft and rotating cylinder are installed at the dew mouth place of clockwork case to clockwork case.In the restorable process of clockwork spring, meanwhile, door is just closed automatically.
Advantage of the present invention is: solved this and closed the door and the problem of not closing the door.Simple in structure, volume is less, is easy to install.Beam barrel has reduced to open the generation of noise at closing time, and the winder core can be regulated the state of clockwork spring easily, thereby can regulate speed and strength at closing time easily.
Description of drawings
Further specify structure of the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is a schematic perspective view of the present invention
Marginal data: 1---door leaf, 2---doorframe, 3---clockwork case, 4---the axle core, 5---locating shaft, 6---rotating cylinder, 7---clockwork spring, 8---sleeve, 9---stressed seat.
The specific embodiment
As shown in the figure, the present invention includes clockwork case 3 that is fixed on the doorframe 2 and the stressed seat 9 that is fixed on the door leaf 1.A core 4 is installed in the clockwork case 3, and axle is wound with clockwork spring 7 on the core 4 and an end is fixed, and the other end of clockwork spring 7 stretches out the back from clockwork case 3 and links to each other with sleeve 8, sleeve 8 be enclosed within stressed seat 9 spool on.When opening the door, along with the motion of stressed seat 9, deformation takes place in clockwork spring 7, and rotating cylinder 6 rotates along with the motion of clockwork spring 7.In order to reduce the friction of 7 pairs of clockwork case 3 of clockwork spring, locating shaft 5 and rotating cylinder 6 are installed at the dew mouth place of clockwork case 3.In clockwork spring 7 restorable processes, meanwhile, door is just closed automatically.
