Abstract

The utility model relates to an automatic door opening and closing device, mainly comprising a bearing seat, a spring, a casing tube, a sliding bar, a sealing damping mechanism, and sealing pipe nuts. The automatic door opening and closing device can make the door automatically shut when the opening angle is less than 85 DEG, and can make the door in the wide open state when the opening angle is more than 85 DEG. The automatic door opening and closing device has damping and buffering action when the door is nearly closed, avoiding severe collision of the door. The utility model has the advantages of light structure, low cost and convenient installation.

Description

Automatic door opening and closing device
The utility model relates to a kind of automatic shutter door gear.
Except that floor spring, have only automatic door closing device in the prior art, still do not possess the opening and closing device of two kinds of functions of open and close simultaneously.And the floor spring complex process, the cost height is installed bothersome.
In view of the deficiency of above-mentioned prior art, the purpose of this utility model is that a kind of door that can make of design is closed automatically, can make door place the automatic shutter door gear of opening-wide state again.
The utility model is made up of supporting base, sleeve pipe, spring, slide bar and tube sealing nut, reaches sleeve pipe on the slide bar and is provided with the buffering damping unit of being made up of piston, air vent, damping hole, seal cartridge.
The utility model has two kinds of functions of shutter door compared with the prior art simultaneously, has the damping buffering effect at closing time, make the action of closing the door soft, and it is simple in structure, and is easy for installation.
Description of drawings:
Accompanying drawing is structural representation of the present utility model and installs and uses view.
Wherein: 1-doorframe, 2-door hinge, 3-door shoulder, 4-supporting base, 5-attachment pegs, 6-sleeve pipe, the 7-spring, 8-nut, 9-piston, 10-tube sealing nut, 11-seal cartridge, the 12-slide bar, 13-attachment pegs, 14-supporting base, 15-air vent, 16-damping hole.
Below in conjunction with accompanying drawing a most preferred embodiment of the present utility model is described.
Shown position is the critical condition (opening angle is 85 °) that this open/close device door leaf opens and closes, and when door opens the angle greater than 85 °, door opens wide, and opens wide extreme position shown in the dotted line of the left side; When door opening angle during less than 85 °, door is closed automatically, shown in the state di sopra dotted line when closing.If must change the critical angle that door is opened, can reach by the height a that changes supporting base 14.
Key component one sleeve pipe of the present utility model and slide bar are as shown in drawings.Wherein 6 is sleeve pipe, makes of cold-drawn steel pipe, and one end and attachment pegs 5 link, and the another port is shaped on screw thread and cooperates with tube sealing nut 10.7 are the compression spring, and it mainly provides the power of automatic opener.12 is slide bar, and its end and supporting base 14 link, and the other end is associated with a piston 9, is shaped on screw thread in this end of slide bar, and the nut of fastening piston 9 is housed.Be shaped on an air vent 15 vertically by threaded end face on the slide bar, radially also be shaped on a damping hole 16 on slide bar 12, damping hole 16 communicates with air vent 15.Slide bar 12 can be used A 3The garden steel is made.Be furnished with a tube sealing nut 10 at an end of sleeve pipe 6, its shape is pressed into a lining that seals 11 as shown in the figure in tube sealing nut 10, and lining 11 is closely spaced being slidingly matched with slide bar 12.
As shown in drawings, when door opening angle during less than 85 °, spring is by slide bar 12, supporting base 14 promotes door and closes automatically, at this moment, spring-loaded space constantly increases in the sleeve pipe 6, and the space at damping hole 16 places constantly is compressed, and air flows to the space at spring place by damping hole 16, air vent 15.When door was about to close, damping hole 16 just in time was in the seal cartridge 11, and the air that be between damping hole 16 and the piston 9 this moment is compressed and can't circulate (the slit micro-leakage is arranged), and this has just played the buffering damping action, made the unlikely fierce collision of door.

Claims (4)

1, a kind of automatic shutter door gear, it comprises supporting base and spring, its feature just is that this device is provided with thrust spring 7, sleeve pipe 6, tube sealing nut 10 and a slide bar 12 that has damping mechanism.
2, open/close device according to claim 1, it is characterized in that along slide bar 12 be axially arranged with air vent 15, radially be provided with damping hole 16, air vent 15 and damping hole 16 communicate.
3, open/close device according to claim 2 is characterized in that an end of slide bar 12 connects a piston 9.
4,, it is characterized in that the end of sleeve pipe 6 is provided with a seal cartridge 11 according to claim 2 or 3 described open/close devices.
