Problems solved by technology

The traditional suspension bracket used to install the projector is mainly composed of a base, a lifting adjustment device, a positioning device and a suspension claw, which has the disadvantages of complex structure and high manufacturing cost; in addition, the traditional suspension projection Instrument bracket also has the following disadvantages:
[0004] 2. Defects in the positioning device
For example, the projector suspension bracket disclosed by the patent No. CN201120388230 uses a pair of U-shaped hooks as a positioning device; when the projector is installed, because the projector is heavy, the strength of the bracket to maintain positioning is mainly concentrated on the U-shaped hooks. On the bolts (equivalent to concentrating on one point), over time, the positioning of the projector is prone to deviation

Abstract

The invention discloses a simple suspension type projector bracket. The projector bracket comprises a pedestal and connecting pieces for connecting a projector, wherein the pedestal (1) is provided with a device for mounting the connecting pieces; the horizontal position of the device on the pedestal is adjustable; each connecting piece is provided with two universal joints (5, 6), of which one is positioned at the upper end and is connected with the pedestal and the other one is positioned at the lower end for connecting the projector; the universal joints (5, 6) at the upper and lower ends of each connecting piece are connected by arranging a lengthening rod (7); the two ends of the lengthening rods (7) are provided with connectors; the connectors at the two ends are matched, namely one lengthening rod can be connected with the other lengthening rod through the connectors. The projector bracket has the advantages of simple structure, reduced manufacturing cost, capability of lengthening infinitely and stability after mounting.

Description

technical field [0001] The invention belongs to the field of projection, and in particular relates to a suspension type projector bracket. Background technique [0002] The application of projectors has become very popular. For projectors used indoors, the projector is usually installed under the suspended ceiling of a building through a suspension bracket. The traditional suspension bracket used to install the projector is mainly composed of a base, a lifting adjustment device, a positioning device and a suspension claw, which has the disadvantages of complex structure and high manufacturing cost; in addition, the traditional suspension projection Instrument bracket also has the following disadvantages: [0003] First, the limitation of the adjustable range of the lifting adjustment device. For example, the projector suspension bracket disclosed by the patent No. CN200910030479 is a lifting adjustment device in the form of a casing, and its adjustable distance is equival...
