Embodiment

[0020] Embodiment: A projector suspension bracket, including a bottom plate 1 fixed under the ceiling, a lifting sleeve 2 and a suspension frame 3 for fixing the projector, with an inverted U-shaped hook on the basis of the direction of use 4. The top of the inverted U-shaped hook is fixed on the bottom plate, and the two sides of the inverted U-shaped hook are respectively provided with a central hole 41 and an arc-shaped groove 42. The central hole and arc-shaped groove on each side of the inverted U-shaped hook The grooves are distributed in concentric circles. The upper end of the lifting sleeve is provided with positioning holes and limit holes. The first bolt 51 passes through the positioning hole at the upper end of the lifting sleeve and the central hole on the side of the inverted U-shaped hook at the same time. The first nut Screwed with the first bolt, the lifting sleeve can rotate around the first bolt to adjust the vertical angle. The vertical angle is limited by t...

Abstract

The invention discloses a projector suspension bracket. The bottom plate of the projector suspension bracket is connected with a lifting sleeve by using an inverted U-shaped hook, so that the verticality of the lifting sleeve can be adjusted, that is, the suspension bracket And the verticality of the projector is adjustable; the length of the lifting sleeve is adjustable, so that the height of the suspension frame and the projector can be adjusted; the length of the telescopic arm is adjustable, so that the suspension frame can fix different types of projectors; the connecting plate A rotatable connection is adopted between the connection head and a friction plate is arranged between the two, so that the angle of the suspension frame and the projector can be adjusted.

Description

technical field [0001] The invention relates to a projector bracket, in particular to a projector bracket suspended under the ceiling. Background technique [0002] At present, projectors have been widely used in conference rooms and exhibition halls to project various flat images. The projector is generally used on the table, but for large-scale conferences, special exhibitions or certain occasions, the projector should not be placed on the table but is required to be hung under the ceiling, then a suspension bracket must be used. At present, there is a kind of suspension bracket, the boom is directly fixed under the ceiling, and the projector is directly connected to the mounting bracket under the boom, which lacks adjustment to each other, and the mounting bracket can only match a certain type of projector, so Difficulties can be encountered when adjusting and replacing projectors. Contents of the invention [0003] In order to overcome the above defects, the present ...
