Abstract

The utility model relates to an electric door positioning and locking mechanism, comprising a machine frame, a motor, a decelerator, a driving roller, a guide rail, etc. The drive transmission of the utility model has the characteristics that the motor is connected with an input shaft of the decelerator via a belt, and an output shaft of the decelerator is provided with a clutch and a driving sprocket which is connected with a driven sprocket on a mandrel via a chain. The utility model is characterized in that the front section and the rear section of the guide rail are provided with cross beams which are provided with limited slide blocks and rack bars, and the lower end of the machine frame is provided with guide wheels which are matched with slide ways on the slide blocks and gears engaged with the rack bars. The adjusting mechanism has the advantages of stable running, and proper and accurate opening and closing; the adjusting mechanism can effectively prevent the hanging guide rail type sliding door from being pushed and lifted by the external force, and the safety and protection function of the hanging guide rail type sliding door is increased.

Description

Electric door position and lock mechanism

The utility model relates to a kind of driving mechanism of electric door, exactly is the driving mechanism that is provided with fixing and locking device.

Opening and closing of all electric door all is to realize by dragging of driving mechanism.Used electric door, in its opening-closing process, when particularly being in open and close and putting in place, although closed drive motors, but under action of inertia, also can move a segment distance, what often be directed at door opens and closes not in place or carry collision, and carry collides, and has greatly influenced the application life of electric door.Moreover, the scroll wheel of electric door and driving mechanism, all be rest on guide rail, what constraint its level and vertical direction all do not have, and under the effect of external force, still can promote or lift driving mechanism, make its getaway, thereby such door does not have the safety precaution effect substantially.

The purpose of this utility model is, in the lower end of driving mechanism and the section of opening and closing of guide rail, is provided with gear, the tooth bar and position limiting slide block that matches and the guide wheel that are meshed, overcomes above-mentioned deficiency.

Its purpose is by following scheme implementation: electric door position and lock of the present utility model mechanism, comprise frame, and be contained in the drive motors on the frame, worm type of reduction gearing, transmission connection piece and be contained in active roller on the axle of frame lower end.Drive motors links to each other with reducer input shaft through belt, on the output shaft of reducer, clutch and drive sprocket is housed, and drive sprocket connects the driven sprocket that is contained on the active roller axle through chain, and the active roller device is being laid on the guide rail on ground.For overcoming this mechanism at the inertia that opens and closes when putting in place, reach external force and do moving and getaway of time spent, crossbeam is housed, position limiting slide block and tooth bar are housed on the guide rail at the front and rear sections place of guide rail, in the lower end of frame, be equipped with position limiting slide block on the guide wheel that matches of guide groove, with the tooth bar meshed gears.For making this mechanism be unlikely to lift getaway by the external force sled, guide groove on the position limiting slide block and the guide wheel that matches with it are processed into match "T"-shaped.For guaranteeing that guide wheel enters guide groove and do not send collision and hard friction, guide wheel with the touching mutually on the face of guide groove, be set with rubber ring and rubber washer.For making the stationarity of this mechanism when moving, below the vertical end of frame one end, to be equipped with one and laterally to play the capture moving axis, the auxiliary wheel with the guide rail interlock is equipped with at the two ends of floating axle.

Because this mechanism design has rack-and-pinion engagement, the guide groove of slide block and guide wheel interlock reach parts such as elastic floating auxiliary wheel, thereby have guaranteed the stationarity of this mechanism when dragging, and open and close the accuracy that puts in place.Simultaneously, mobile the reaching that has also prevented from effectively to try hard to recommend outside under moving prized leaving the right or normal track of lifting, and strengthened the safety precaution effect of door.

Electric door position and lock of the present utility model mechanism is provided by following examples and accompanying drawing thereof.

Fig. 1 is the structure chart according to the electric door position and lock mechanism that the utility model proposes.

Fig. 2 is the sectional view of Fig. 1 along B-B.

Fig. 3 is the sectional view of Fig. 1 along C-C.

Below in conjunction with the details of Fig. 1～3 detailed descriptions according to the electric door position and lock mechanism that the utility model proposes.

This mechanism comprises frame [2], is contained in the drive motors [16] on the frame, worm type of reduction gearing [3], transmission connection piece and be contained in active roller [15] on the axle of frame lower end, be laid on ground and with the guide rail [10] of active roller interlock.It is in transmission connection and is, drive motors links to each other with reducer input shaft through belt, on the output shaft of reducer, clutch [18] and drive sprocket [17] is housed, and drive sprocket is through chain, links to each other with driven sprocket [13] on being contained in the active roller axle.The active roller axle is installed in the lower end of frame through bearing support [12].At guide rail front and rear sections place, be welded with transverse beam [11], [14], be separately installed with tooth bar [5], position limiting slide block [9] on it.On the active roller axle, be equipped with and tooth bar meshed gears [4], below the frame front end, be equipped with position limiting slide block on the guide wheel [6] that matches of guide groove, guide groove on the position limiting slide block and the guide wheel that matches, be processed into match "T"-shaped, on the path of guide wheel, be set with rubber ring [7], rubber washer [8].Below frame rear end, a transverse elasticity floating axle [1] is housed, the auxiliary wheel with the guide rail interlock is equipped with at its two ends.

Claims
