Abstract
The utility model relates to an automatic door-closing device comprising a connecting rod movably connected with a door and a driving box fixedly arranged on a door frame or a wall body. The driving box is internally provided with a driving spring, a driving gear and a transmission gear matched with the driving gear; one end of the driving spring is connected with the driving box and the other end is connected with a wheel shaft of the driving gear; one end of the connecting rod is movably connected with a connecting seat arranged on the door and a driving cog matched with the driving gear is arranged at the other end of the connecting rod; and the connecting seat is provided with a positioning magnet for positioning. The utility model can automatically close the door at uniform speed and achieve the aim of stably closing the door; when the door is required to be opened for a long time, the positioning can be realized by only opening the door to the maximum degree, thereby increasing the positioning function and more conveniently using; in addition, the conversion between the position and automatic door closing is simple, thus the utility model is convenient to use.
Description
Technical field
The utility model relates to a kind of closing device, relates in particular to a kind of door engine that utilizes the gear drive in the mechanical-physical to realize.
Background technology
What use basically in existing civilian construction is that passive type is closed the door, and needs manually control to close the door, and uses extremely inconvenient.In public, realize closing the door automatically, generally adopt door closer is installed on door, but rely on door closer of the prior art to realize closing the door automatically also having more problem, as close a speed be difficult to control, always do not close the door automatically when having manpower control, the user can not be selected as required, function is more single, in ZL99204179.1, the slip working beam is set on the door closer, back-moving spring, slip working beam and rod hinge connection, connecting rod and operation block are hinged, operation block is by axle, bearing is arranged on the body, be positioned to be set with on this external and swinging block that operation block is fixedlyed connected and close a connecting rod, close a connecting rod and survive with movable sleeve and be connected, movable sleeve and fixed mount are hinged.This kind adopts the windproof door closer of frame for movement, though overcome many defectives of fluid pressure type door closer, the problems referred to above are not resolved, and makes the door closer can not extensive use.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that existing closing device exists, a kind of door engine is provided, the utility model is uniform and automatic closing the door, reach stable purpose of closing door, when needs open the door for a long time, only door need be reached maximum angle and can realize the location, increased positioning function, use conveniently, and location and the conversion of closing the door automatically are simple, easy to use.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of door engine, comprise the connecting rod that flexibly connects with door, it is characterized in that: also comprise the gear box that is fixedly installed on doorframe or the body of wall, the travelling gear that is provided with transmission clockwork spring, driven wheel in the described gear box and cooperates with driven wheel, transmission clockwork spring one end is connected with gear box, the other end is connected with the wheel shaft of driven wheel, connecting rod one end is gone up the Connection Block that is provided with door and is flexibly connected, the other end is provided with the driving cog that cooperates with travelling gear, and Connection Block is provided with the positioning magnet that is used to locate.
Described gear box is provided with rail groove, and the transmission increment of connecting rod is arranged in the rail groove and cooperates with travelling gear.
Described positioning magnet is two, is arranged on the Connection Block two ends and cooperates the location with the metal gear box.
Adopt advantage of the present utility model to be:
One, the utility model is provided with the transmission clockwork spring in gear box, the transmission clockwork spring is connected with driven wheel, and driven wheel drives travelling gear, and travelling gear drives connecting rod and realizes closing the door automatically, utilize the gear drive in the mechanical-physical to realize at the uniform velocity closing automatically of door, reach stable purpose of closing door.
Two, the utility model Connection Block is provided with the positioning magnet that is used to locate, and when door reached maximum, positioning magnet cooperated the location with the metal gear box, increased positioning function, use conveniently, and location and the conversion of closing the door automatically are simple, easy to use.
Three, the utility model is simple in structure, and Maintenance free owing to close the door at the uniform velocity closing automatically, makes and moves in the Men Zaiguan closed procedure steadily, and no rapid movement has been avoided the wearing and tearing of door, has increased the application life of door.

The specific embodiment
A kind of door engine, comprise the connecting rod 1 that flexibly connects with door 2, also comprise the gear box 4 that is fixedly installed on doorframe or the body of wall 3, the travelling gear 7 that is provided with transmission clockwork spring 5, driven wheel 6 in the described gear box 4 and cooperates with driven wheel 6, transmission clockwork spring 5 one ends are fixedlyed connected with gear box 4, the other end is connected with the wheel shaft of driven wheel 6, the Connection Block 8 that is provided with on connecting rod 1 one ends and the door 2 flexibly connects, the other end is provided with the driving cog that cooperates with travelling gear 7, and Connection Block 8 is provided with the positioning magnet 9 that is used to locate.
The course of work of the present utility model is as follows:
When opening the door, connecting rod 1 is in 10 motions of the thrust lower edge of door 2 rail groove, by 7 motions of the cogged drive belt nutating gear on the connecting rod 1, thereby travelling gear 7 drives driven wheel 6 motions and drives 5 motions of transmission clockwork spring, transmission clockwork spring 5 is in tightens up the state storage energy, when door loses motive force, transmission clockwork spring 5 releases energy, drive driven wheel 6 and rotate, driven wheel 6 drives travelling gears 7 and rotates, bar 1 motion that is dynamically connected of the cogged drive belt of travelling gear 7 on connecting rod 1, connecting rod 1 drives door through Connection Block 8 and closes automatically, when needing the location, door is reached maximum angle, make positioning magnet 9 cooperate the location with metal gear box 4.
