Projector light pipe fixing device and projector

Abstract

The invention discloses a projector light pipe fixing device and a projector, belonging to the field of light guiding. The device comprises a light pipe cladding part (1) and a clamping element (2), wherein the light pipe cladding part (1) is provided with a cavity for accommodating a light pipe (4); two first end faces (11) and second end faces (12) vertical to the center axis of the light pipe, three side faces parallel to the center axis of the light pipe and a third opening (13) are arranged on the periphery of the cavity; the first opening (13) is used for filling the light pipe (4); a second opening (11a) is formed in the first end face (11); a third opening (12a) is formed in the second end face (12); the area of the second opening (11a) is less than that of the first end face (11), and the area of the third opening (12a) is less than that of the second end face (12); and the clamping element (2) comprises a clamping part and a connecting part positioned at the end part of the clamping part; and the light pipe cladding part (1) is enclosed and clamped by the clamping part, and the connecting part is used for fixedly connecting a projector shell.

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, due to the way the cover 5 is fixed by dispensing glue, the cover 5 has the risk of retreating, or the cover 5 will be deformed, which will cause problems such as blocking the optical path
