Abstract

The invention discloses an electric ceiling blind which comprises tracks arranged at two sides, wherein end covers are connected at two ends of the tracks; a belt is arranged in the tracks; and two ends of the belt are respectively connected to gears in the end covers and are driven by the gears. The electric ceiling blind is characterized in that the gear at one end of each track is connected with a motor for opening and closing the ceiling blind. The inner side of the belt is arranged to be tooth-shaped, so that the contact surface formed when a pulley and the belt are fixed is enlarged, and the stressing is uniform; the gears and the tooth-shaped belt are in meshing transmission, so that deformation of the belt can be avoided, and the service life of the belt is prolonged; double motors are arranged at one ends of the tracks of the ceiling blind, so that the load capacity of the ceiling blind is enhanced, and the electric ceiling blind has wide application range; and the other ends of the tracks of the ceiling blind are connected through a synchronous connecting shaft, so that the double motors are subjected to compulsory synchronous rotation in a mechanical mode, and tiny differences are eliminated.

Description

A kind of electric ceiling blind

Technical field

The present invention relates to a kind of ceiling blind, especially a kind of by the motor-driven electric ceiling blind of folding curtain.

Background technology

Electric ceiling blind is mainly used in the Motorized blind system of aspect, skylight, can be used for the large-scale lighting roofs such as market, hotel, office building, also can be used for the places such as senior house solaria, flower stand, lunar calendar balcony and regulate preference temperature in sunshade, holding chamber, avoid high light radiation, improve daylighting effect.

The single square motor of the many employings of existing ceiling blind drives, and stroke limit adopts mechanical type spacing, and easy stroke positioning causes light leak, and debugging is more difficult, the Shi Zehui that is hampered in motor operation course blocks so that damages motor, and single motor driving force is limited, has usually limited to it and has used.In addition, the transmission mechanism belt used is general as Figure 1-1, belt 1 ' is evenly equipped with multiple perforation 2 ', the dolly of fixing ceiling blind fabric is fixed on belt 1 ' by perforation 2 ' thus, but, such fixed form, the contact surface of dolly and belt 1 ' is less, and discontinuity, easily impacts transmission.Accordingly, with this kind of belt with the use of gear then as shown in Figure 1-2, the tooth 4 ' of gear 3 ' axis is in tip shape, through belt 1 ' perforation 2 ' thus drive belt 1 ' transmission, but, owing to being in the process of transmission, sharp-pointed tooth 4 ' is inserted in perforation 2 ', difficult alignment and easily by belt 1 ' lengthening deformation, affect the service life of belt 1 ', affect the service life of ceiling blind.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.

See Fig. 2, a kind of electric ceiling blind, comprise the track 1 being positioned at both sides, the two ends of track 1 are connected with end cap, and one end of every bar track 1 is provided with folding curtain motor 2, and the other end is connected by the track 1 of synchronous connecting shaft 3 by both sides.Owing to employing folding curtain motor 2, stroke limit is that electronic type is spacing, there will not be stroke positioning to cause light leak; and folding curtain motor 2 can be hampered and stop; effectively protect motor, track 1 also can be different from existing straight track thus, and becomes the curved track with radian.

See Fig. 3, be provided with belt 12 in track 1, the two ends of belt 12 connect end cap respectively.The inner side of belt 12 is profile of tooth, and coaster 41 is fixed on belt 12 by fixture 411, has larger contact surface between fixture 411 and belt 12, stressed relatively more even, makes transmission respond well.Be provided with gear 111 in the end cap of track 1, the tooth of gear 111 and the profile of tooth of belt 12 match, and both intermesh, and drive belt 12 to slide thus by the rotation of gear 111, owing to being engaged transmission, can not cause the distortion of belt 12 thus easily.

The fabric 4 of ceiling blind, be generally sunshade textile, the end of its both sides is fixed on coaster 41, the remainder of both sides is evenly provided with pulley 42, when the running of folding curtain motor 2 drives belt 12 to slide, the end of fabric 4 slides under the drive of belt 12 in track 1, remainder sliding through pulley 42 and can slide in track 1 then according to end.

Because folding curtain motor 2 is likely due to manufacturing process, small asynchrony phenomenon may be there is thus.Arrange synchronous connecting shaft 3 track 1 of both sides is connected, realize forced synchronism mechanically, thus eliminate small difference.See Fig. 4-Fig. 6, synchronous connecting shaft 3 comprises and connects main shaft 21, and connecting main shaft 21 can directly connect by heel end lid, and also can be that the two ends connecting main shaft 21 are connected with Coupling Shaft 22 respectively, Coupling Shaft 22 connects end cap more respectively.In order to make, without the need to regulating the length connecting main shaft 21 also can normally use, to connect main shaft 21 and adopt the mode be socketed, as being socketed in Coupling Shaft 22 by connection main shaft 21 with Coupling Shaft 22.Rotating shaft 221 diameter that the outside of Coupling Shaft 22 connects increases, and its end being arranged with jump ring 222, preferably, is C type, rotating shaft 221 to be fixed.End cap comprises the drive end bearing bracket 11 and rear end cap 23 that are connected to each other, and rotating shaft 221 is located through the centre bore 235 of rear end cap 12, and coordinates with the gear 111 in drive end bearing bracket 11.The outside bottom surface of rotating shaft 221 is symmetrically arranged with the first arc bulge loop 223, accordingly, the inside bottom surface of gear 111 is symmetrically arranged with the second arc bulge loop 112, first arc bulge loop 223 and the second arc bulge loop 112 is worked in coordination, form a full circle, and belt 12 is arranged on gear 111.Thus, when belt 12 driven gear 111 rotates, gear 111 can drive turning cylinder 22 to rotate, thus is delivered to the turning cylinder 22 of opposite side by connecting main shaft 21, forces to realize being synchronized with the movement of two side gears 111 and belt 12.

Carrying out conveniently is installed, and rear end cap 23 adopts buckle type to be connected with drive end bearing bracket 11.Rear end cap 23 is provided with hasp 231 near the side of fabric 4, be installed in rear end cap 23 by torsion spring 232 and positioning transfer axle 233, the outer circumference of the centre bore 235 of rear end cap 23 is symmetrically arranged with the first arc ring 234 extended radially outwardly from centre bore 235, the corresponding position, installing hole 113 position of the inner side of drive end bearing bracket 11 is symmetrically arranged with the second arc ring 114 extended internally from outer periphery.During installation, the second arc ring 114 is positioned at the first arc ring 234 outside radially, and its medial surface radially abuts with the first arc ring 234 lateral surface radially, thus prevents rear end cap 23 from moving up and down.Hasp 231 is placed in the breach 115 of drive end bearing bracket 11 side under the active force of torsion spring 232, does side-to-side movement to prevent rear end cap 23.When needs dismounting synchronous connecting shaft 3, only need rotate hasp 231 leaves breach 115.

The foregoing is only the preferred embodiment of the present invention, it should be pointed out that for the ordinary skill in the art, not departing under principle prerequisite of the present invention, can also make various deformation and improvement, this also should be considered as protection scope of the present invention.
