Problems solved by technology

[0003] Now, with the popularization and use of projectors, hanging projectors can no longer fully meet people's needs. It often happens that projectors are not installed in advance in places where projectors are needed. Temporary projector brackets will cause projectors to The playback effect of cannot meet the requirements
[0004] In order to solve the problem of inconvenient use of the projector bracket, a Chinese patent (publication number: CN207716003U) discloses a mobile projector bracket, which includes a tripod bracket, a lifting bracket and a projector bracket. By adjusting the tripod bracket and the lifting bracket, the Adjust the position of the projector, but after the projector is placed, it is easy to move up and down due to factors such as the weight of the projector when adjusting the height manually, making it difficult to adjust to an accurate position, which affects viewing

Abstract

The invention relates to the technical field of electronics, in particular to a movable projector bracket capable of finely adjusting the height. The movable projector bracket comprises an outer shell; the top of the outer shell is fixedly connected with a push rod motor; an output shaft of the push rod motor is fixedly connected with an inner shell; a first bevel gear is mounted in the inner shell; a screw cap is arranged in the first bevel gear; a screw rod is in threaded connection into the screw cap; the top of the screw rod is fixedly connected with a connecting rod; the top of the connecting rod is rotationally connected to a placing table; a self-locking motor is fixedly connected to the outer wall of the right side of the inner shell; and an output shaft of the self-locking motor is fixedly connected with a second bevel gear. The movable projector bracket is suitable for places requesting precise projection of projectors on screens; after the projectors move by proper distancesand angles, a push rod motor is controlled for rough adjustment of the height, and the self-locking motor is controlled to rotate; under the effects of gear engagement and threaded connection, the height is finely adjusted; and the device can randomly move to achieve convenience and flexibility, achieves high height adjusting precision, and can totally match the projectors on curtains to bring comfortable experiences for lookers.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a mobile projector bracket whose height can be finely adjusted. Background technique [0002] A projector is an optical instrument that uses optical components to enlarge the outline of a workpiece and project it onto a video screen. Projectors are currently widely used in homes, offices, schools and entertainment venues. According to different working methods, there are CRT, LCD , DLP and other different types. [0003] Now, with the popularization and use of projectors, hanging projectors can no longer fully meet people's needs. It often happens that projectors are not installed in advance in places where projectors are needed. Temporary projector brackets will cause projectors to The playback effect of cannot meet the requirements. [0004] In order to solve the problem of inconvenient use of the projector bracket, a Chinese patent (notification number: CN207716003U) dis...
