Abstract
The utility model provides a projector lifting device capable of being remotely controlled during the English teaching and relates to a projector lifting device, particularly a projector lifting device capable of being remotely controlled during the English teaching. The utility model aims to solve the problem during the conventional English teaching process that, since the height of a projector is adjusted through manually adding objects at the bottom of the projector, the height adjustment of the projector is troublesome, time-consuming and labor-consuming. According to the technical scheme of the utility model, a drive motor is arranged at the middle part of the upper surface of a mounting platform. The rotating shaft of the drive motor is inserted into the lower end of a spiral lifting sleeve. The upper end of the spiral lifting sleeve is fixedly connected to the middle part of the lower surface of a lifting platform. A first supporting shaft seat is arranged at the middle part of the upper surface of the lifting platform. Two second supporting shaft seats are arranged side by side and parallel to each other on the lower surface of a projector bearing platform. The first supporting shaft seat is inserted between the two second supporting shaft seats. A rotating shaft sleeve sequentially passes through the first supporting shaft seat and the two second supporting shaft seats. The projector lifting device is adapted during the English teaching process.
Description
Technical field
The utility model relates to a kind of lifting/lowering device for projector, be specifically related in a kind of English teaching can long-distance remote control lifting/lowering device for projector.
