Detailed Description
The utility model provides an electric rotating shaft support.
Referring to fig. 1, fig. 1 is a perspective view of an embodiment of the present invention.
As shown in fig. 1, in an embodiment of the present invention, the electric spindle bracket includes: the projector fixing device comprises a fixing plate 100 fixedly connected with a mounting frame of the projector and a hanging bracket 200 fixedly connected with the projector, wherein the hanging bracket 200 is positioned below the fixing plate 100, and a first end of the fixing plate 100 is rotatably connected with a first end of the hanging bracket 200.
The second end of the fixing plate 100 is provided with a driving motor 300, an output rotating shaft of the driving motor 300 is coaxially connected with a screw rod 400, and the screw rod 400 vertically penetrates through the fixing plate 100 downwards. The screw rod 400 is connected with a driving block 500 in a threaded manner, two side walls of the driving block 500 are provided with sliding pins 510, and the two sliding pins 510 are coaxially arranged. Two limiting plates 600 are arranged at the top of the second end of the hanging bracket 200, the two limiting plates 600 are arranged at two sides of the driving block 500, the two limiting plates 600 are respectively provided with an elongated sliding hole 610 which is obliquely arranged, and the two sliding pins 510 respectively slide in the elongated sliding holes 610.
When the projection angle of the projector needs to be adjusted, the motor is controlled to rotate only through an external controller, so that the screw rod 400 is driven to rotate. The screw 400 rotates to drive the driving block 500 to move up and down, and the driving block 500 moves up and down to drive the hanging bracket 200 to rotate around the first end through the sliding fit of the sliding pin 510 and the strip-shaped sliding hole, so that the projection angle of the projector fixed at the bottom of the hanging bracket 200 can be adjusted.
Further, in this embodiment, first tab portions 110 extending downward are disposed at both sides of the first end of the fixing plate 100, second tab portions 210 extending upward are disposed at both sides of the first end of the hanger 200, and the first tab portions 110 and the second tab portions 210 are hinged by a pin 700. By providing the first and second tab portions 110 and 210, a sufficient space for rotation is provided between the fixing plate 100 and the hanger 200.
Further, in the present embodiment, the first tab portion 110 is integrally formed with the fixing plate 100 by a bending process, so that the first tab portion 110 has a sufficient connection strength with the fixing plate 100, and the second tab portion 210 is also integrally formed with the hanger 200 by a bending process, so that the second tab portion 210 has a sufficient connection strength with the hanger 200.
Further, in this embodiment, the pin 700 is sleeved with a damping washer 710 and an adjusting nut 720, the adjusting nut 720 is in threaded connection with the pin 700, and the adjusting nut 720 abuts the damping washer 710 against the corresponding second tab portion 210. Through setting up damping gasket 710 and adjusting nut 720, can adjust round pin axle 700 rotation in-process damping force size as required.
Further, in this embodiment, the damping pad 710 is provided with a limiting protrusion 711, the second tab portion 210 is provided with a limiting hole 211 corresponding to the limiting protrusion 711, and the limiting protrusion 711 is inserted into the limiting hole 211 corresponding to the limiting protrusion 711, so as to prevent the damping pad 710 from rotating together with the pin 700 and the adjusting nut 720, which may cause the damping pad 710 and the second tab portion 210 to generate an excessive damping force due to friction.
Further, in the present embodiment, the fixing plate 100 is further provided with a fan heat dissipation hole 120. During installation, a heat dissipation fan can be installed above the fan heat dissipation holes 120 according to needs, and the heat dissipation fan dissipates heat of the hanger 200 and the projector fixed at the bottom of the hanger 200 through the fan heat dissipation holes 120.
Preferably, in this embodiment, the damping pad 710 is a disc-shaped pad, and the deformable space of the disc-shaped pad is larger than that of a common pad, so that the damping adjustment range is larger, and the damping adjustment is more accurate.
Compared with the prior art, the utility model has the beneficial effects that: the electric rotating shaft support can drive the projector fixed on the electric rotating shaft support to swing at a certain angle, so that the projection angle of the projector can be adjusted.
