Embodiment 1

[0017] The present invention is a projector with a side-mounted bulb, comprising a bulb cover 1, a cover screw 2, a bulb assembly 3, a handle 4, an assembly fixing screw 5, a bulb power socket 6, and a projector 7. On the side of the projector 7, there is The side opening 8 is provided with a light bulb power socket 6; the side has a side opening 8 in which the light bulb assembly 3 can be inserted or pulled out; the light bulb assembly 3 is connected to the projector 7 with assembly fixing screws 5, and the light bulb assembly There are cooling holes 9, positioning posts 13, power plugs and handles 4 on 3; there is a light bulb in the light bulb assembly 3, after the light bulb assembly 3 is inserted into the side opening 8, the power plug is inserted into the light bulb power socket 6 at the same time; there is a light bulb on the side opening 8 The cover plate 1 has buckles 10 on the bulb cover plate 1, and the buckle 10 clamps the bulb cover plate 1 on the projector and fix...

Embodiment 2

[0019] According to a kind of side-removable bulb projector described in Embodiment 1, a safety switch 11 is provided on the projector 7, and a safety switch ejector rod 12 is provided on the bulb cover 1. When the bulb assembly 3 is inserted, the switch is turned on, and the projection The projector can work normally, and the switch is disconnected when the bulb assembly 3 is pulled out, and all power is cut off in the projector to prevent electric shock accidents.

Embodiment 3

[0021] attached image 3 It is a schematic diagram of the structure of Embodiment 3 of the present invention. According to the side-mounted bulb projector described above, the projector 7 and the bulb cover 1 are connected by a hinge 14; question.

[0022] To sum up, the opening of the bulb in the present invention is placed on the side of the projector, and the maintenance personnel can stand on the side to disassemble and assemble, so that the maintenance of the bulb assembly and the replacement of the bulb can be easily realized, and the hazards of bulb debris and foreign objects can be avoided. Maintenance personnel.

Abstract

A projector with a bulb detached laterally comprises a bulb cover plate, cover plate screws, a bulb assembly, a handle, assembly fixing screws, a bulb power socket and a projector body. The projector is characterized in that the side face of the projector body is provided with a side open hole, the bulb power socket is arranged in the side open hole, the bulb assembly is inserted in the side open hole in the side face, the bulb assembly and the projector body are connected through the assembly fixing screws, the bulb assembly is provided with heat dissipation holes, locating pillars, a power plug and the handle, the bulb is arranged in the bulb assembly, the bulb cover plate is arranged on the side open hole, buckles are arranged on the bulb cover plate, and the bulb cover plate is fixed to the projector body through the cover plate screws. The projector has the advantages that a bulb opening is formed in the side edge of the projector body, so that maintenance of the bulb assembly and replacement of the bulb are realized conveniently, and it is avoided that bulb fragments and foreign matter harm maintenance personnel.

Description

technical field [0001] The invention relates to a projector, in particular to a structure for disassembling and replacing projection bulbs. Background technique [0002] At present, for projectors that use high-pressure mercury lamps as light sources, the bulbs need to be removed, dusted or replaced after the brightness has decayed. The existing projectors have a bulb cover on the top or bottom of the projector, so that the bulb assembly can be easily taken out for correlation. maintenance action. This design will cause some troubles when the maintenance personnel work. If the projector is operated upside down, the debris inside the bulb assembly (the bulb may burst out some broken glass, or there are foreign objects such as dust) may fall down and damage the operation. Personnel safety (e.g. in eyes or other body parts). Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a projector with s...
