Abstract
The utility model relates to an automatic air switch, which belongs to the technical field of an intelligent automatic air switch. A DC motor, a motor bracket and a casing are connected together. A pinion gear arranged on an output shaft of the DC motor is engaged with gears 3, 2 to make a driving shaft rotate. A sleeve barrel is sheathed on the driving shaft. The inner threads of the sleeve barrel are screwed and combined with the outer threads arranged on the driving shaft to make the sleeve barrel move, and a U-shaped steel sheet arranged on the sleeve barrel moves following the sleeve barrel to drive the air switch to be open and closed. The utility model can be used for industrialization automatic control.
Description
Affiliated technical field
The utility model belongs to intelligent automatic air-break switch technical field.
Background technology
Air switch in the prior art, a kind of is the intelligent automatic air-break switch that has stopping means, this product has following defective, the one, it can not be threaded off automatically, and motor is suppressed, and burns out motor, two be to use the life-span short, reliability is relatively poor, bring some inconvenience to use.
Summary of the invention
In order to overcome the defective of prior art, the utility model provides a kind of and can thread off automatically, protects motor, improves the intelligent air switch of useful life and reliability.
The technical solution of the utility model is to realize like this, the contrast accompanying drawing describes, automatic air-break switch is characterized in that, as shown in the figure: direct current machine 6 is fixed on the electric machine support 4, electric machine support is fixed on the housing 9, one pinion 5 is installed on the direct current machine output shaft, and it is meshed with gear 3, and the axle of inlaying gear 3 is fixed on the housing by bearing 1 and 18, gear 2 is embedded on the power transmission shaft 11, and gear 2 is meshed with gear 3.Power transmission shaft is fixed on the housing by bearing 19 and 10, position at power transmission shaft has external screw thread 21, and be with sleeve 12, on an end of sleeve, internal thread is arranged, it screws mutually with external screw thread on the power transmission shaft, it is moved on power transmission shaft, the other end at sleeve is equipped with plate washer 17, U-shaped steel plate 14 is enclosed within on the sleeve, back-moving spring 13 and 16 is contained in two places up and down of U-shaped steel plate, the keying handle 15 of air switch 7 is contained among the U-shaped steel plate, and housing 9 is fixed on the air switch by screw 20, and the 8th, the binding post of air switch.Air switch belongs to known technology and repeats no more.Pinion 5 on the direct current arbor is meshed with gear 3, gear 2 is meshed with gear 3, slow down and drive power transmission shaft and rotate, the internal thread of sleeve and the external screw thread on the power transmission shaft screw, sleeve is moved on power transmission shaft, when moving to two limit positions (even ending place, moving axis screw thread two ends) time, sleeve stops, back-moving spring 13 and 16 elastic force are in internal thread of sleeve and power transmission shaft external screw thread all the time and screw initial state, and positive engagement when guaranteeing counter-rotating at any time, on sleeve, be with the keying handle that the U-shaped steel plate is used to drive air switch and move back and forth, to realize the disconnection and the closure of air switch.
The beneficial effects of the utility model, when air switch disconnects and is closed, external screw thread is in two limit positions on the internal thread of sleeve one end and the power transmission shaft, i.e. external screw thread ending place on the power transmission shaft, power transmission shaft idle running at this moment, transmission mechanism is threaded off, to avoid transshipping the damage that motor is caused, reach the excessive damage of Motor torque to mechanical structure, also reduced waste simultaneously to the energy, make product component be in a kind of good working order all the time, prolonged the useful life of product.
