Abstract
The utility model discloses a quick speed door opener, which comprises a machine frame, a power output apparatus, a driving shaft, a driving bearing seat, a door shaft, and a door shaft seat, wherein the driving shaft is arranged in the driving bearing seat; the door shaft is arranged in the door shaft seat; the power output apparatus is connected with the driving shaft. The driving shaft is connected with a rocker arm, a connecting rod is fixedly installed on the door shaft and a sliding rail is arranged on the connecting rod. One end of the rocker arm slides in the sliding rail. The quick speed door opener of the utility model effectively solves the contradiction between the fast door opening speed and easy damage of the inertia of the door, and can achieve self locking effect of the door.
Description
Technical field
The utility model relate to speed that a kind of door gear of automatic switch in public, particularly clamshell doors device carry out control door opener fast.
Background technology
The present public arena access door control device that uses, general complex structure, volume ratio is bigger, as be used for the rotation gate inhibition of subway inlet, the double-acting door of entrance, this gating device, often since the space narrower and small, it is constant that the people who carries luggage is come in and gone out, and if the opening amplitude of this gating device is bigger, then can be owing to amplitude makes switching speed slow greatly, if and significantly improve switching speed, not only cost significantly promotes, and because inertia of door itself, make vibrations big, fragile.
The utility model content
At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of and opens the door fast but can not damage the door opener fast of door.
The technical solution adopted in the utility model is: a kind of door opener fast, comprise frame, power take-off, driving shaft, driving shaft bearing, door-hinge, the door-hinge seat, driving shaft is arranged in the driving shaft bearing, and door-hinge is arranged in the door-hinge seat, and described power take-off is connected with driving shaft, on described driving shaft, be connected with rocking arm, be installed with connecting rod on door-hinge, connecting rod is provided with slide rail, and an end of described rocking arm slides in described slide rail.
Described slide rail can be provided with a slide block that flexibly connects in the termination of described rocking arm for being opened in the chute on the connecting rod, and rocking arm slides in the chute of connecting rod by this slide block.
Described driving shaft can be connected for semifixed with rocking arm, and the opening axis hole is arranged on the rocking arm, uses bolt on the both sides on the opening axis hole, on this bolt regulating spring is housed.
Described slide block can be parallel with the corresponding opposite side of chute.
The minimum angles of rocking arm and connecting rod can be 90 degree.
Described rocking arm can be curved shape, and described connecting rod can be curved shape.
Door opener fast of the present utility model, owing between rocking bar and door-hinge, set up connecting rod, on connecting rod, be provided with slide rail, an end of rocking arm slides along described slide rail, the driving shaft pendulum rotating shakes arm, drivening rod rotates, and realizes the switching of door, efficiently solves the fast and flimsy contradiction of the inertia of door of the speed of opening the door own, in addition, because the minimum angles of rocking arm and connecting rod is 90 degree, this is that the power that acts on the connecting rod can't make the rocking arm swing effectively, thereby can reach the self-locking effect of door.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is rocking arm and connecting rod 90 degree self-locking schematic diagrames;
The specific embodiment
Shown in Fig. 1-2, door opener fast of the present utility model comprises frame 1, power take-off 5, driving shaft 3, drive shaft bearing seat 2, door-hinge 12, door-hinge bearing support 4, driving shaft 3 are arranged in the driving shaft bearing 2, door-hinge 12 is arranged in the door-hinge seat bearing 4, described power take-off 5 is connected with driving shaft 3, is connected with rocking arm 7 on driving shaft 3, is installed with connecting rod 8 on door-hinge 12, connecting rod is provided with chute 13; termination of rocking arm 7 is provided with a slide block 9 that flexibly connects, and rocking arm 7 slides in the chute 13 of connecting rod 8 by slide block 9, and driving shaft 3 pendulum rotating shake arm 7; drivening rod 8 rotates, and realizes the switching of door 6.
Described slide block 9 is substantially parallel with chute 13 corresponding corresponding sides, in the full swing position of rocking arm 7,8 one-tenth 90 degree of rocking arm 7 and connecting rod are because 8 one-tenth an angle of 90 degrees of rocking arm 7 and connecting rod, the power that acts on the connecting rod can't make rocking arm 7 swings effectively, thereby can reach the self-locking effect.Rocking arm 7 or connecting rod 8 itself can be crooked.
Can also further improve: driving shaft 3 is semifixed connection with being connected of rocking arm 7, when the load of rocking arm 7 surpasses certain value; rocking arm and driving shaft slide; described semifixed connection is such; the opening axis hole is arranged on the rocking arm, on the both sides on the opening axis hole fixed bolt hole is arranged, and spring 11 is arranged on the bolt 10; by the decrement of regulating spring 11, reach the load intensity of regulating rocking arm 7.
Can also further improve: described quick-opening device has one near switch, and this is installed on connecting rod 8 or the rocking bar 7 near switch, and this switch is connected with power take-off 5, and power take-off 5 is closed rapidly.
