Abstract
The utility model belongs to cabin door driving devices, in particular to a lead screw transmission cabin door driving device capable of being switched to automatic mode or manual mode, which aims at solving the problems that an electric cabin door is large in transmission resistance, low in transmission efficiency, prone to fault, short in service life, large in output power of motor and the like which exist in the prior art, and a cabin door driving device can not achieve switch between the manual mode and the automatic mode as required at any time. The technical scheme is that a magnetic attraction device arranged on a sliding block controls a magnetic attraction pressure rod to be pressed down or lifted, and the lower end of the magnetic attraction rod is connected with a lead screw nut capable of meshing with or separating from a lead screw. The lower portion of the lead screw nut is provided with a spring, and a slide block in clearance match with the lead screw is arranged on a slide box, thereby enabling a cabin door body to drive a transmission box to slide on the lead screw through a connecting rod. The lead screw transmission cabin door driving device capable of being switched to automatic mode or manual mode can be applied to manufacture and use of various cabin door driving devices and switch between the automatic mode and the manual mode as required at any time.
Description
Technical field: the utility model belongs to warehouse door driving device, particularly a kind of changeable be the lead screw transmission warehouse door driving device of automatic or manual pattern.
Background technology: existing storehouse door has manually and electronic two kinds.Manually the storehouse door is used the manpower switch, and is with low content of technology, operation inconvenience.Electric warehouse door is worn electric control box, generally is divided into two kinds of tooth bar transmission and chain drives, adopts machine driving such as gear, sprocket wheel to realize the storehouse door switch.The electric warehouse door of this transmission exists the transmission resistance big, and transmission efficiency is low, and easy fault, and application life is short, and the motor power output is big, problem such as special effort when power failure needs the hand switch door.And can't realize carrying out at any time as required warehouse door driving device manual or that automatic mode switches.
Summary of the invention: the purpose of the utility model is exactly the technical scheme that proposes a kind of warehouse door driving device of the lead screw transmission that can separate automatically; Exist with the solution background technology: the transmission resistance is big; Transmission efficiency is low, and easy fault, and application life is short; The motor power output is big, problem such as special effort when power failure needs the hand switch door.And can't realize carrying out at any time as required warehouse door driving device manual or that automatic mode switches.Solving this technical problem the technical scheme that is adopted is: a kind of changeable lead screw transmission warehouse door driving device of automatic or manual pattern that is; Storehouse every body connects with the slip case through coupling bar; Motor connects with leading screw on being positioned at fastening devices, and the slip case is connected on the leading screw, it is characterized in that the electromagnetism adhesive device control electromagnetism adhesive depression bar that is provided with on the sliding shoe presses down or rises; Electromagnetism adhesive depression bar lower end connect can with the feed screw nut of leading screw interlock or disengagement; Feed screw nut bottom is provided with spring, and the sliding shoe with the leading screw matched in clearance also is set on the slip case, makes the Ku Menmen body drive transmission case through connecting rod and on leading screw, slides.Wherein, the energising of electromagnetism adhesive device or the quick switching device of outage also are set on the sliding shoe.The feed screw nut Lower Half does not have screw thread.
The beneficial effect that the utility model and prior art comparison are had is: adopt technique scheme; When connecting electromagnetism adhesive device power supply, attract electromagnetism adhesive depression bar to move down, electromagnetism adhesive depression bar promotion feed screw nut moves down and is tight with the interlock of leading screw the first half simultaneously; Feed screw nut the latter half and leading screw are thrown off; Spring is compressed, and the forward and reverse rotation of motor-driven leading screw drives the transmission case move left and right; Because the Ku Menmen body connects with the slip case through connecting rod, realize the open and close of storehouse door automatic mode through slip case move left and right.When breaking off electromagnetism adhesive device power supply; Being compressed the spring promotion feed screw nut and the electromagnetism adhesive depression bar that tighten up moves up; Feed screw nut and leading screw the first half are thrown off, have only sliding shoe to contact on the slip case, promote the Ku Menmen body this moment with leading screw; Connecting rod drives transmission case and can on leading screw, be free to slide, and switches to the manual mode of open and close.Like this, whole device transmission resistance is little, and transmission efficiency is high, and noise is low, long service life, and rapid operation, and can carry out manually perhaps automatic mode switching as required at any time.
Description of drawings:
Fig. 1 is the utility model overall structure sketch map.
The specific embodiment:
With reference to figure 1; A kind of changeable be the lead screw transmission warehouse door driving device of automatic or manual pattern, Ku Menmen body 11 connects with slip case 5 through coupling bar 10, motor 9 connects with leading screw 1 on being positioned at fastening devices 8; Slip case 5 is connected on the leading screw 1; It is characterized in that on the sliding shoe 5 that the electromagnetism adhesive device 4 control electromagnetism adhesive depression bars 3 that are provided with press down or rise, electromagnetism adhesive depression bar 3 lower ends connect can with the feed screw nut 2 of leading screw 1 interlock or disengagement, feed screw nut 2 bottoms are provided with spring 6; Sliding shoe 7 with leading screw 1 matched in clearance also is set on the slip case 5, makes Ku Menmen body 11 drive on transmission cases 5 leading screws 1 and slide through connecting rod 10.The energising of electromagnetism adhesive device 4 or the quick switching device of outage also are set on the sliding shoe 5.Feed screw nut 2 Lower Halves do not have screw thread.
