The starting rotary button is switched on and dialed, and the small car drives the curtain to close and open. When arrive at the other end of the curtain, the small car automatically stops. The utility model has the characteristics of novel structure, and convenient operation, and the electric curtain box can be matched at the surface of a circular-arc-shaped window to be used.

Description

The electrically driven curtain box

It is essential that the utility model relates to the human lives, is a kind of electrically driven curtain box.

Have multiple pelmet commodity to select for use in the market, be used for protecting curtain and be convenient to mobile curtain for people, but all can only adapted on the window of plane.Occur novel arc balcony and window in the modern architecture, needed adapted arc pelmet.

The purpose of this utility model provides a kind of electrically driven curtain box, and it can be used in novel structure, easy to use on the arc window.

The purpose of this utility model is to realize like this, the electrically driven curtain box is made up of pelmet, dolly, track, control box, pelmet is oval arc, there is the cavity cavity bottom that moves for dolly to be provided with oval arc track in the pelmet, control box links to each other with dolly in the pelmet by electric wire and is provided with bidirectionally limited K switch 2 and micro machine M in the dolly, the dolly bottom is provided with rubber covered rollers, is provided with worm and gear deceleration train between micro machine M and the roller; Control box is provided with firing switch K1 and indicator lamp L.

The electrically driven curtain box is action like this, when the moved end of curtain ties up on the dolly, connects power supply, stirs starting turn-knob K1, dolly just moves along track in pelmet, drives curtain and closes, when dolly arrives the pelmet end, bidirectionally limited K switch 2 actions, so outage, dolly stops.When needing to open curtain, as long as oppositely stir K1, curtain will be opened, and arrives the other end until dolly

Characteristics of the present utility model are: the energy adapted is the window place of circular arc on the surface, novel structure is easy to use.

Embodiment further narrates below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of electrically driven curtain box;

Fig. 2 is the structure cross-sectional schematic of dolly;

Fig. 3 is the circuit theory diagrams of electrically driven curtain box.

Among the figure: 1-pelmet, 2-dolly, 3-track, 4-control box, 5-roller

6-worm and gear deceleration train K1-firing switch K2-bidirectionally limited switch

M-micro machine, 50W, direct current 220V, 1400 rev/mins of R-resistance

C-electrochemical capacitor D1, D2, D3, D4-diode L-indicator lamp

Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, be exemplary embodiments of the present utility model, pelmet is oval arc, long 5M, arc radius 4M, system makes with hard plastic board, the outer wide 70MM of form height 80MM of pelmet, and track is that aluminium section bar is made, the housing of dolly and control box is made by the ABS plastic mold pressing, the outer wide 50MM of form height 60MM of dolly, roller diameter 15MM, the electrically driven curtain box of present embodiment adopts the alternating current 220V power supply, be provided with in the control box by D1, D2, D3, the rectification circuit that D4 and C form is confessed the 220V direct current and is used to micro machine.When power connection, indicator lamp L is bright.Starting turn-knob K1 has three positions, left, center, right, if K1 is allocated to left position, the micro motor for driving roller is with 120 rev/mins of rotations, and curtain is moved to the left thereupon, and until arriving left end, limit switch K2 action this moment is cut off the circuit dolly and stopped; If K1 is dialled to the right, then micro machine counter-rotating, curtain moves right, until arriving right-hand member.

In the present embodiment, be remote control switch if start button K1 changed into, pelmet just has distant control function so, and this electrically driven curtain box is just more novel, made things convenient for.

Claims (1)

1. The electrically driven curtain box is made up of pelmet (1), dolly (2), track (3), control box (4), it is characterized in that:

   Pelmet is oval arc, and the cavity that moves for dolly is arranged in the pelmet, and cavity bottom is provided with oval arc track, and control box links to each other with dolly in the pelmet by electric wire; Be provided with bidirectionally limited K switch 2 and micro machine M in the dolly (2), the dolly bottom is provided with rubber covered rollers (5), is provided with worm and gear deceleration train (6) between micro machine M and the roller; Control box (4) is provided with starting turn-knob K1 and indicator lamp L.
