Projector light pipe fixing device and projector

Abstract

The invention discloses a projector light pipe fixing device and a projector and belongs to the field of light guide. The device comprises a light pipe covering part (1), a clamping element (2) and a stopping plate (3), wherein the light pipe covering part (1) comprises an accommodating cavity for accommodating a light pipe (4), a first end face (11), four lateral side faces and a first opening (12) are arranged at/in the periphery of the accommodating cavity, the first opening (12) is used for installing the light pipe (4), a second opening (11a) is formed in the first end face (11), and the size of the second opening (11a) is smaller than that of the first end face (11); the clamping element (2) comprises a clamping portion and a connecting portion arranged at the end of the clamping portion, the clamping portion encloses and clamps the light pipe covering part (1), and the connecting portion is used for being fixedly connected with a casing of the projector; the stopping plate (3) is used for being matched with the first opening (12), and the size of the stopping plate (3) is larger than that of the first opening (12).

Description

technical field [0001] The invention relates to the field of light guides, in particular to a projector light pipe fixing device and a projector. Background technique [0002] A projector is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal to achieve a large-screen projection display. way to provide viewers with excellent presentation and visual effects. With the development of electronic technology, projectors are widely used in education, business and home. According to the different working principles of projectors, they can be divided into cathode ray tube projectors (CRT), liquid crystal projectors (LCD) and digital optical processing projectors (DLP). Among them, the imaging principle of the digital optical processor projector is: the light emitted by the optics is transmitted to the digital microscopic device in the ope...

Problems solved by technology

Although the structure of the fixture is simple, due to the long cycle and unstable quality of the UV glue dispensing process, the position of the LP varies with the vibration and drop; secondly, when the amount of UV glue dispensing is too large, it will interfere with the external clamping components, causing Fixing is not firm; in addition, because the cover body 5 is fixed without glue, the cover body 5 has the risk of retreating, or the cover body 2 will be deformed, which will cause problems such as the optical path being blocked
