Description

The electric window-opening device

Technical field

The utility model relates to a kind of device that is used for Switch for door and window, especially a kind of electric window-opening device.

Technical background

Along with the progress of society, household electrical appliance are a large amount of enters family, brings great convenience for people's live and work.Yet the electric device that is applied to family's door and window automatic open and close seldom.Adopted by a lot of communal facilitys though use more glass door automatic open and close electric control mechanism on the market, it is only applicable to the rail mounted sliding door, and the cost height, generally is not suitable for average family.And chain type electric window-opening device, sliding intelligent window all exist complex structure, volume big, defectives such as poor sensitivity.

Summary of the invention

The purpose of this utility model is the deficiency at above-mentioned existence, and a kind of electric window-opening device that is applicable to the hinge engaging structure window is provided.

The utility model electric window-opening device, it is characterized in that: form by base, motor, Worm and worm-wheel gearing and the handle of cranking arm, described motor is fixedly mounted on the base, the worm screw of worm and gear transmission is installed on the base by bearing support, worm shaft end is docked with motor shaft, the worm gear of described Worm and worm-wheel gearing is installed on the main shaft, the coaxial installation handle of cranking arm on the main shaft, worm gear and cranking arm are provided with one between handle not only can make the handle of cranking arm rotate synchronously, but also can break away from the clutch of worm gear with worm gear.

The design principle and the using method of the utility model electric window-opening device are: utilize motor and transmission mechanism to handle to crank arm handle to promote window and open or close.This electric window-opening device is installed in frame bottom, the handle end of cranking arm of electric window-opening device is connected with window, is under the mated condition when regulating clutch, when motor is just changeing, then can the handle of cranking arm be rotated around the main shaft clockwise direction by transmission mechanism, the handle end be pushed window open by cranking arm; When changeing behind the motor, the handle of cranking arm is rotated around the spindle axis counterclockwise direction, by the handle end of cranking arm the window of opening be retracted and close.When the adjusting clutch was in released state, the handle of cranking arm disengaging cooperated with worm gear, and the handle of cranking arm promptly is in free state, and this moment, window just was in manual state, and people can use the keying of hand direct control window.

The utility model electric window-opening device design science, simple and reasonable for structure, transmission is sensitive reliable.Easy to use, by the keying that can realize window that turns to of control motor.This shows that this electric window-opening device utilizes software program control by the electronic signal of various kinds of sensors acquisition or the signal of Digiplex emission if join and corresponding automaton, can realize the intellectuality control of window by the control to the window opener motor.The instructions for use that window is closed automatically when satisfying people's far distance controlled dwelling house window or meeting with wind and rain.

The concrete structure of the utility model electric window-opening device is provided in detail by the following drawings and embodiment.

Description of drawings

Fig. 1 is the structural representation of electric window-opening device;

Fig. 2 is an A-A shown in Figure 1 position sectional structure schematic diagram.

Embodiment: can be clear that from Fig. 1, the electric window-opening device has a base 1, base 1 is provided with and is used for the through hole 2 that it is installed in frame bottom, motor 3 is installed on the base 1 by junction plate 4, the worm screw 6 of Worm and worm-wheel gearing 5 is installed on the base 1 by bearing support 7, worm screw 6 axle heads are connected by shaft coupling 8 with motor 3 axle heads, one main shaft 9 is vertically mounted on the base 1, be equipped with on the main shaft 9 with the worm gear 10 of worm screw 6 engagement with manner and be nested with thereon the handle 11 of cranking arm, the other end of handle 11 of cranking arm is provided with the hanging hole 12 that is connected with window, the worm gear 10 and 11 of the handles of cranking arm are provided with clutch 13, clutch 13 is by the gear 14 that is installed on the main shaft 9, ring gear 15, back-moving spring 16 and gland 17 constitute (see figure 2), the engagement that can be nested of gear 14 and ring gear 15, gear 14 is fixedlyed connected with worm gear 10 sides, ring gear 15 is fixedlyed connected with handle 11 sides of cranking arm, back-moving spring 16 is nested with on the main shaft 9 of 15 of gear 14 and ring gears, gland 17 is installed in handle 11 outside main shafts 9 ends of cranking arm, pressing the elastic force that gland 17 can impel the handle 11 of cranking arm to overcome back-moving spring 16 downwards moves down, the ring gear 15 that is arranged on handle 11 sides of cranking arm moves down and 14 engagements of worm gear 10 side gears synchronously, and this moment, worm gear 10 can drive handle 11 rotations of cranking arm.When no external force acted on gland 17, ring gear 15 broke away from gear 14 under the effect of back-moving spring 16, and this moment, worm gear 10 can not drive handle 11 rotations of cranking arm, and the handle 11 of cranking arm is in manual state.

The course of work of this electric window-opening device: the ring gear 15 of handle 11 sides of cranking arm is meshed with the gear 14 of worm gear 10 sides, this moment is when motor 3 is just changeing, driving worm screw 6 is just changeing, worm screw 6 drives worm gear 10 just to be changeed, worm gear 10 drives handle 11 clockwise directions of cranking arm by clutch 13 and rotates, and the handle 11 of cranking arm is pushed connected window open; When motor 3 counter-rotatings, drive worm screw 6 counter-rotatings, worm screw 6 drives worm gear 10 backward rotation, and worm gear 10 drives the handle 11 of cranking arm by clutch 13 and counterclockwise rotates, and the handle 11 of cranking arm retracts connected window and closes.This electric window-opening device can be realized the intellectuality control of window if join and corresponding automaton.
