Problems solved by technology

[0004] Since the previously disclosed patents belong to the fact that each leg is independent of each other, it is necessary to adjust each leg repeatedly and in turn during adjustment to adjust the projected image to the most appropriate image, which is quite inconvenient in the adjustment operation. Therefore, a synchronous adjustment The inclination adjustment mechanism is required by the current market

Abstract

The invention relates to an inclination angle regulation mechanism for a projector. The inclination angle regulation mechanism comprises a shared pole, a pair of cam surfaces, a pair of driven parts and a pair of floor mats, wherein the shared pole is arranged in a shell in a reciprocating way; one cam surface is formed at each end of the shared pole; the pair of cam surfaces are symmetrical about the shared pole; one ends of the pair of driven parts are pressed against the cam surfaces, and the other ends of the pair of driven parts are extended out of the shell for the arrangement of the pair of floor mats; and the shared pole is driven to reciprocate to be pressed against the pair of driven parts through the pair of cam surfaces, and the pair of driven parts further drives the floor mats to synchronously regulate distances, namely a distance between the other floor mat and the shell is prolonged when a distance between one floor mat and the shell is shortened; therefore, the effectof synchronously and conveniently regulating an inclination angle of the projector is achieved.

Description

technical field [0001] The invention relates to a projector, in particular to an inclination adjustment mechanism of the projector. Background technique [0002] When setting up the projector, it is necessary to adjust the height, left and right inclination of the projected image according to the differences in environmental conditions, installation location, etc., so that users can watch the most appropriate image. [0003] A kind of inclination adjustment mechanism disclosed as China Taiwan Patent No. 528916 is to set independent adjustment screws in front of the projector housing to adjust the inclination angle of the projected image of the projector, and China Taiwan Patent No. I250369 discloses a This adjustment mechanism also belongs to the independent adjustment of each leg. [0004] Since the previously disclosed patents belong to the fact that each leg is independent of each other, it is necessary to adjust each leg repeatedly and in turn during adjustment to adjus...
