Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.

Referring to fig. 1-4, a hidden curtain device mainly comprises an electric curtain 1, a base 2 and an arm 3; the number of the bases 2 is 2, and the bases are respectively positioned at the left end and the right end of the electric screen 1; arm pole 3 is equipped with 2, and a base 2 connects an arm pole 3.

The electric curtain 1 is internally provided with a motor and a stroke limiting device; the lower end of the curtain 11 of the electric curtain is provided with a lower shaft 12, and the lower shaft 12 adopts a heavy object such as a stainless steel pipe. The two ends of the electric curtain 1 are provided with fixing frames 13, and the bottom edge of each fixing frame 13 is provided with a hollow first strip-shaped hole 14.

A screw hole is arranged above the base 2, and a first bolt 21 is correspondingly arranged; a first bolt 21 penetrates through a first strip-shaped hole 14 of the fixing frame to install the electric curtain 1 on the base 2; the fixing frame 13 adopts a strip-shaped hole, so that the electric curtain 1 has a certain adjustable space on the base 2. A row of limiting holes 22 are arranged in the front end of the base 2 in an inner measuring way, in the embodiment, 5 limiting holes 22 are arranged in one row in an inclined way, the position of the limiting hole which is most close to the front is lowest, and the position of the limiting hole which is most close to the back is highest; a limiting bolt 23 is further arranged, and the limiting bolt 23 is connected with one limiting hole 22 to limit the inclination angle of the arm rod 3 after being put down; when the limit bolt 23 is connected to the limit hole 22 at the most front (see fig. 2), the angle of the arm 3 which is put down is the largest, which is equivalent to horizontal; when the stop pin 23 is connected to the rear stop hole 22 (see fig. 3 and 4, and connected to the fourth stop hole), the arm 3 is lowered at a small angle and is in an inclined state. The connection between the limiting bolt 23 and the limiting hole 22 adopts a threaded connection structure. A fixing plate 24 is arranged on the base 2, a second strip-shaped hole 25 is arranged on the fixing plate 24, and a second bolt 26 is correspondingly arranged; the second bolt 26 passes through the second strip hole 25 to fix the base 2 to the hanger plate a1 below the ceiling light groove a.

One end of the arm lever 3 is hinged to the inner side of the base 2 through a third bolt 31, and the middle part of the third bolt 31 is not provided with threads so that the arm lever 3 can swing on the third bolt 31; the other end of the arm rod 3 is provided with a forked head 32 which is in a tiger mouth shape; the lower shaft 12 of the curtain is placed in the diverging head 32. A torsion spring 33 is arranged between the arm lever 3 and the base 2, and the torsion spring 33 acts on the arm lever 3 to enable the upper end of the arm lever 3 to incline forwards; the torsion spring 33 is fixed to the base 2 by a fourth bolt 34. First rollers 35 are arranged between the two arms 3 and at the bottom of the fork head 32 for connection, so that when the curtain 11 slides down between the two arms 3, damage caused by friction is reduced.

Further, the second roller 15 is disposed at the exit of the curtain 11 of the electric curtain 1 and below the curtain, so as to prevent the curtain 11 from directly rubbing against the electric curtain housing.

The rear side of the electric curtain fixing frame 13 is provided with a fixing hole 16, so that in the embodiment, after the base 2 is detached, the electric curtain 1 can be fixed on a wall or hung under a suspended ceiling like a common curtain.

The curtain outlet of the electric curtain 1 is positioned at the front upper part, so that the length of the arm 3 can be increased, and the curtain 11 can be hung after being moved forwards greatly.

With respect to the torsion spring 33, an appropriate torsion force is selected so that when the screen is being let out, the spring has a sufficient torsion force to tilt the arm 3 forward; when the curtain is retracted, the motor can pull the arm rod to retract the curtain.

The stroke limiting device of the electric curtain is conventional technology in the field, and the embodiment is not detailed.

During installation, the device is arranged in a light trough of a suspended ceiling, and the base 2 is fixedly arranged on a hanging plate A1 below the light trough A through bolts. In the structure of the ceiling lamp groove, some lower hanging plates A1 are flat (shown in figure 2), and the limiting bolt 23 is connected to the second screw hole 22 at the front, so that the arm rod 3 can be laid flat when the curtain is released; the edge of the hanging plate A1 below some light grooves is convex (see figure 3), and the limit bolt 23 is connected with the limit hole 22 at the back, so that the arm lever 3 is kept at a certain inclined angle when the curtain is released.

In the process of retracting and releasing the curtain 11, when the curtain is released, the arm rod is under the action of the torsion spring 33 and supports the lower shaft of the curtain to move forwards, and after the arm rod moves to the rigid outer side below the lamp groove, the curtain continuously drops along with the action of the weight of the lower shaft until the curtain completely drops; when the curtain 11 is retracted (indicated by the dotted arrow in fig. 3), the curtain is raised, and when the curtain is raised to a certain extent, the two ends of the lower curtain shaft 12 are embedded in the branch heads 32 of the arm rods 3, and the ends of the branch heads of the arm rods are supported until the branch heads of the arm rods abut against the housing of the electric curtain.

The above is only one embodiment of the present invention, and for those skilled in the art, the details of the changes made without departing from the principles of the present invention should be considered as belonging to the protection scope of the present invention.
