The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present application, it is to be understood that the terms "longitudinal," "lateral," "horizontal," "top," "bottom," "upper," "lower," "inner" and "outer" and the like are used in the orientation or positional relationship shown in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1-3, the utility model provides a projector support for teaching, including mounting panel 10, guide rail 20, slider 30, lead screw 40, motor 50 and controller 60. The mounting plate 10 is fixedly connected with the wall at the top of the classroom through a plurality of connecting rods 11. The guide rails 20 are provided with two, the two guide rails 20 are fixedly arranged at the bottom of the mounting plate 10 along the transverse direction, and the two guide rails 20 are kept parallel. The sliding block 30 is disposed on the two guide rails 20 and is slidably connected to both of the two guide rails 20. The projector 80 is fixedly mounted on the bottom of the slider 30. The first end of the screw rod 40 is rotatably connected with the mounting plate 10, the second end of the screw rod 40 is also rotatably connected with the mounting plate 10 after transversely penetrating through the sliding block 30, and the screw rod 40 is in threaded connection with the sliding block 30 and is parallel to the two guide rails 20. The motor 50 is fixedly installed on the mounting plate 10 and is used for driving the screw rod 40 to rotate. A controller 60 is mounted on top of the mounting plate 10 and is electrically connected to the motor 50, the controller 60 being capable of controlling the operation of the motor 50.

When the controller 60 controls the motor 50 to work, the output shaft of the motor 50 can drive the screw rod 40 to rotate. When the screw 40 rotates, under the action of the guide rail 20, the slider 30 moves back and forth on the mounting plate 10, and the projector 80 on the slider 30 also moves back and forth, so that the distance between the projector 80 and the curtain can be adjusted, and more requirements of a user can be met.

In one embodiment, a lift mechanism 70 is also included that is disposed on the slide 30. The lifting mechanism 70 comprises a fixed block 71, an electric push rod 72 and a bottom plate 73. The fixed block 71 is fixedly installed at the bottom of the slider 30, and an accommodating groove 74 extending upward is formed at the bottom of the fixed block 71. The two electric push rods 72 are respectively arranged on two sides of the fixed block 71 along the longitudinal direction and are electrically connected with the controller 60. The upper end of the electric push rod 72 is fixedly connected with the fixed block 71. The bottom plate 73 is transversely arranged below the fixed block 71 and is fixedly connected with the lower end of the electric push rod 72. The projector 80 is fixedly mounted on the top of the bottom plate 73 and located right below the accommodating groove 74, and the size of the projector 80 is adapted to the size of the accommodating groove 74.

After the user uses the projector 80, the controller 60 can control the two electric push rods 72 to simultaneously retract, so as to drive the bottom plate 73 to ascend. Eventually, the projector 80 on the base plate 73 enters the receiving groove 74. Therefore, on one hand, the excessive accumulation of dust in the air on the projector 80 can be prevented, and the situation of unclear projection in subsequent use is avoided; on the other hand, the projector 80 can be protected, and the projector 80 is prevented from being damaged when students are playful in classrooms.

In one embodiment, the size of the projector 80 is smaller than the size of the receiving groove 74, and there is a gap between the projector and the wall of the receiving groove 74 after entering the receiving groove 74. Thus, when the electric push rod 72 drives the bottom plate 73 to ascend, the projector 80 can smoothly enter the accommodating groove 74, and collision or friction between the projector 80 and the groove wall of the accommodating groove 74 is avoided.

In one embodiment, a gasket 75 is also mounted on the top of the bottom plate 73, and the gasket 75 is fitted to the bottom of the fixing block 71. When the projector 80 completely enters the accommodating groove 74, the accommodating groove 74 can be better isolated from the external environment due to the existence of the sealing gasket 75, dust in air is prevented from entering the accommodating groove 74, and cleanness of the projector 80 is further guaranteed.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
