Abstract
A rotation driving device of a door closer comprises an input shaft and an output shaft. A connector is arranged between the input shaft and the output shaft, both ends of the connector is provided with an upper connecting piece and a lower connecting piece, the upper connecting piece and the lower connecting piece are respectively connected with a roller through a vertical rotation shaft, the input shaft and the output shaft are respectively provided with a left connecting piece and a right connecting piece which are transversely connected onto the corresponding roller through a transverse rotation shaft. According to the rotation driving device of the door closer, the transmission between the input shaft and the output shaft is of a cardan joint structure which is high in transmission efficiency, small in size, easy to process, low in costs, smart in design and capable of avoiding roller breakdown caused by overhigh frequency or speed.
Description
Technical field
The utility model relates to a kind of door closer, and is especially a kind of for the rotating driving device on the door closer.
Background technique
At present, the use of door closer more and more widely, some concealed door closers particularly, this door closer can be hidden in door or the doorframe, by the rotation of concealed slide rail and rocking arm driving gate, keep the aesthetic feeling of door originally.Present technology generally is external mounted, adopts umbrella tooth engagement driving, realizes 90 ° of being in transmission connection of turning between input shaft and the output shaft.But this structure has certain shortcoming, and this structural volume of the first is big, and for concealed door closer, for ease of being installed in door or the doorframe, door closer is more little more attractive in appearance, so the volume size of door closer is extremely important; It two is that the umbrella gear transmission efficiency is low, and the required rotatory force of external mounted door closer is bigger, and transmission efficiency is low then to cause the driving load of door closer motor internal big, shortens the working life of motor so greatly.
The model utility content
The utility model will solve the shortcoming of above-mentioned prior art, and the rotating driving device on a kind of door closer is provided, and this drive unit adopts gimbal structure, and simple in structure, volume is little, and the transmission efficiency height.
The utility model solves the technological scheme that its technical problem adopts: the rotating driving device on this door closer, comprise input shaft and output shaft, wherein be provided with link between input shaft and the output shaft, the two ends of link are respectively equipped with connecting sheet and following connecting sheet, last connecting sheet and following connecting sheet are connected with roller by vertical rotating shaft, wherein be respectively equipped with left connecting sheet and right connecting sheet on input shaft and the output shaft, left connecting sheet and right connecting sheet laterally are connected on the roller by horizontal rotating shaft.Modular construction in this structure is simple, is convenient to processing, and parts are easy to assembly, and the volume of the joint after the assembling is equivalent to the volume of link, and overall volume is little; During transmission, the rotation of input shaft directly drives output shaft by link, has increased transmission efficiency.And this crooked angle that is in transmission connection can rotate flexibly, and is low for the position accuracy demand of the assembling of door closer.
For further perfect, wherein roller is provided with the through hole of decussate texture, wherein connecting sheet, through hole and following connecting sheet are passed in vertical rotating shaft successively, wherein have perforation in the vertical rotating shaft, wherein laterally the axle center of rotating shaft has the fixed hole that passes for rivet, wherein rivet pass fixed hole and perforation and with vertical rotating shaft and laterally rotating shaft be fixed together.Wherein laterally have keyway on the inner of rotating shaft, have draw-in groove in the vertical rotating shaft, wherein laterally rotating shaft is connected in the draw-in groove.This structural design is ingenious, and the disengaging roller phenomenon because of the too fast generation of frequency excessively high speed can not take place.
The effect that the utility model is useful is: being in transmission connection between the utility model input shaft and the output shaft adopted the structure of universal joint, this structure transmission efficiency height, volume is little, processing is simple, cost is low, this structural design is ingenious, and the disengaging roller phenomenon because of the too fast generation of frequency excessively high speed can not take place.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: the rotating driving device on this door closer, comprise housing 7, input shaft 1 and output shaft 2, input shaft 1 connects motor 8, wherein be provided with link 3 between input shaft 1 and the output shaft 2, the two ends of link 3 are respectively equipped with connecting sheet 3-1 and following connecting sheet 3-2, last connecting sheet 3-1 and following connecting sheet 3-2 are connected with roller 4 by vertical rotating shaft 5, wherein be respectively equipped with left connecting sheet 1-1 and right connecting sheet 1-2 on input shaft 1 and the output shaft 2, left connecting sheet 1-1 and right connecting sheet 1-2 laterally are connected on the roller 4 by horizontal rotating shaft 6.
Wherein roller 5 is provided with the through hole 5-1 of decussate texture, wherein connecting sheet 3-1, through hole 5-1 and following connecting sheet 3-2 are passed in vertical rotating shaft 5 successively, wherein have perforation 5-1 in the vertical rotating shaft 5, wherein laterally the axle center of rotating shaft 6 has the fixed hole 6-1 that passes for rivet 6-3, wherein rivet 6-3 pass fixed hole 6-1 and perforation 5-1 and with vertical rotating shaft 5 and laterally rotating shaft 6 be fixed together.Wherein laterally have keyway 6-2 on the inner of rotating shaft 6, have draw-in groove 5-2 in the vertical rotating shaft 6, wherein laterally rotating shaft 6 is connected in the draw-in groove 5-1.This structural design is ingenious, and the disengaging roller phenomenon because of the too fast generation of frequency excessively high speed can not take place.
Being in transmission connection between the utility model input shaft 1 and the output shaft 2 adopted the structure of universal joint, this structure transmission efficiency height, and volume is little, and processing is simple, and cost is low, and this structural design is ingenious, and the disengaging roller phenomenon because of the too fast generation of frequency excessively high speed can not take place.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
