Description

Technical Field

[0001] This utility model relates to the field of projector installation equipment technology, specifically an auxiliary mounting bracket for a ceiling-mounted projector in a multimedia classroom. Background Technology

[0002] In multimedia classrooms, overhead projectors are widely used due to their advantages, such as not taking up classroom space and their projection effect not being disturbed by people walking around. However, the installation process of overhead projectors currently presents many inconveniences.

[0003] Traditional installation methods typically require installers to hold the projector at a height for positioning and fixation. Since the projector itself has a certain weight, holding it for a long time can easily cause arm fatigue for the installer, thus affecting installation accuracy and causing problems such as projector installation position deviation and inaccurate angle, which in turn affects the projection effect. Moreover, if it is necessary to make fine adjustments to the position or angle of the projector during the installation process, it is necessary to repeatedly disassemble and reinstall it, which is cumbersome, inefficient, and also increases the safety risks for the installer.

[0004] To address the problems existing in the above technologies, an auxiliary mounting bracket for a ceiling-mounted projector in a multimedia classroom is proposed. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an auxiliary mounting bracket for a ceiling-mounted projector in a multimedia classroom, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary mounting bracket for a ceiling-mounted projector in a multimedia classroom, comprising:

[0007] The crossbar has a slide rail fixedly installed at its bottom;

[0008] The projector adjustment mechanism is located below the slide rail and is used to adjust the position of the projector relative to the crossbar in the vertical direction.

[0009] The docking bracket, located at the bottom of the projector adjustment mechanism, is used to support the projector and has mounting holes for docking with the projector.

[0010] Raise the crossbeam to the top of the classroom and secure it with screws. Then place the projector on the mounting bracket, select the mounting hole corresponding to the projector's mounting position, and secure it with screws. Push the telescopic lever to slide it along the slide rail via the slider, precisely adjusting the projector's horizontal position. Move the front or rear of the tilt adjustment piece to adjust its pitch angle until the projected image is in the correct position and there is no obvious trapezoidal distortion. Tighten the first and third locking bolts to fix the projector's position. The installer climbs the ladder and, based on the precise positioning of the mounting bracket, easily completes the final tightening of the projector's hoisting screws or the connection to the fixed bracket. Disconnect the mounting bracket from the projector and remove the entire unit.

[0011] As a preferred embodiment of this utility model, the projector adjustment mechanism includes a slider that is slidably connected to the slide rail, a telescopic sleeve fixedly installed at the bottom of the slider, and an angle adjustment component that is rotatably installed at the bottom of the telescopic sleeve.

[0012] As a preferred embodiment of this utility model, the slider and the telescopic sleeve are respectively equipped with a first locking bolt and a second locking bolt.

[0013] As a preferred embodiment of this utility model, the bottom end of the tilt adjustment component is connected to the docking frame via a hinge, and a third locking bolt for locking the tilt adjustment component and the docking frame is installed on one side of the tilt adjustment component.

[0014] As a preferred embodiment of this utility model, a heat sink is fixedly installed on the upper surface of the docking frame.

[0015] As a preferred embodiment of this utility model, a thermally conductive pad is installed on the lower surface of the docking frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By transforming the tedious aerial fine-tuning work into convenient ground / low-level operations, the projector avoids repeated ladder climbing for adjustments. A single person can complete most of the fine-tuning work, significantly shortening installation time. Through a precise position adjustment mechanism, the projector's horizontal position and tilt angle can be adjusted very conveniently and accurately, ensuring that the projected image is centered and square (reducing trapezoidal distortion) and achieving the best projection effect. This reduces the time and number of times installers need to perform fine-tuning operations at heights and lowers the risk of falls. Attached Figure Description
