CN2301934Y - Electric window curtain device - Google Patents

Abstract

The utility model relates to an electric window curtain device, composed of a curtain rail, a bearing, a motor, a control switch and a pulley wheel. The utility model is characterized in that the motor is connected and rotated with a shaft on the other end of the bearing via a thin screw-thread wire rope. A nut on the wire rope is driven to move in an opposite direction via the motor. The curtain then can be switched. The utility model has the advantages of simple structure, smooth transmission, strong pulling force, low noise, small vibration, small size, power consumption saving and safety. The electric window curtain device has no speed variation devices and is a splendent ornament for hotels, meeting rooms, offices and families.

Description

A kind of electrically driven curtain device

The utility model relates to a kind of electronic folding window shade arrangement.

At present, there is Yi Kasheng in the folding of existing hand-operated curtain device on the market, breaks, draws numbness diseases such as motionless.In recent years some electrically driven curtain device motor majorities that emerge in large numbers all have strap speed varying or speed change gear, and its annex is more, volume is big, complex structure, noise is big, fault is many.Another kind of core motor axle, original motor shaft is just very little, adds that again axle is hollow, so the central siphon wall is just very thin, rotor two does not have bearing again simultaneously, just two copper sheathings, when the motor high speed rotating drags curtain open/close, just some faults will inevitably occur, also difficulty is installed.Just directly change the principle of hand-operated curtain device into the motor transmission with upper type.

The purpose of this utility model provides the simple electrically driven curtain device of a kind of drive mechanism.

The purpose of this utility model is achieved through the following technical solutions, it comprises guide bead, respectively there is a box body at these rail two ends, bearing holder (housing, cover) rigid bearing in the one end box body, there is one on the bearing, motor and bearing are housed in the other end box body, an amount of pulley and corresponding hook are arranged on the guide bead, electric switch control motor changes or stops, be that screw steel wire rope by the very thin steel wire coiling of multiply links to each other between bearing, screw thread is therefrom turned round to two ends and is made two kinds of rotation directions, from middle equidistant one nut is arranged respectively on the screw steel wire rope, two nuts are loaded onto annex, and the electrical appliance switch is controlled the folding of curtain.

Screw steel wire rope of the present utility model is by 3 to 10 stainless steel wire coilings, and respectively there is a damping ring two ends box body and screw steel wire rope junction.

The isolation slide block is arranged between the pulley on the utility model guide bead.

Effect of the present utility model has been to reduce the structure of existing electrically driven curtain driving section complexity, is difficult for breaking down, and towing tension is strong, voice is low, power consumptive province, safe and reliable.

Further illustrate the utility model below in conjunction with accompanying drawing.

Figure one is a structure principle chart of the present utility model.

Figure two is enlarged drawings that the utility model screw steel wire rope cooperates with nut.

The utility model adopts rotating high speed 24V direct current generator (12), electric switch is given motor by 220V AC rectification transformation, guide bead (3) links to each other with the two ends box body, one end box body inner fixed bearing cover (1), bearing (2), fixed electrical machinery (12) and bearing (11) in the other end box body, axle on the bearing of two box bodys connects motion thread steel wire rope (7), two nut (6) and (8) that rotation direction is opposite are arranged on the screw steel wire rope (7), the nut top is pulley (4), place on the track, the below is a hook (5), some pulleys (4) are arranged on the track, following hanging hook (5), between the pulley (4) on the guide bead (3) isolation slide block (9) is arranged, connect motor (12) when electric switch and drive also rotation synchronously of screw steel wire rope (7), two nuts are just done oppositely to move along the screw steel wire rope, thereby realize the folding of curtain, by middle end one vibrationproof circle (10) is arranged respectively at box body.

Claims (3)

1, a kind of electrically driven curtain device, comprise guide bead (3), respectively there is a box body at these rail two ends, bearing holder (housing, cover) (1) rigid bearing (2) in the one end box body, there is one on the bearing (2), motor (12) and bearing (11) are housed in the other end box body, an amount of pulley (4) and corresponding hook (5) are arranged on the guide bead (3), electric switch control motor (12) changes or stops, it is characterized in that bearing (2), (11) axle on is that the screw steel wire rope (7) by the very thin steel wire coiling of multiply links to each other, screw thread is therefrom turned round to two ends and is made two kinds of rotation directions, and screw steel wire rope (7) is gone up respectively has a nut (6) from middle equidistant, (8), the thread rotary orientation of two nuts is opposite.

2, electrically driven curtain device according to claim 1 is characterized in that described screw steel wire rope is by 3 to 10 stainless steel wire coilings, and respectively there is a damping ring (10) two ends box body and screw steel wire rope (7) junction.

3, electrically driven curtain device according to claim 1 and 2 is characterized in that between the pulley (4) on the guide bead (3) isolation slide block (9) being arranged.
