The present invention relates to a lamp tube support structure and, more particularly, to a lamp tube support piece of low cost, simple structure, and easy assembly.
As shown in FIGS. 1 and 2, a prior art office business machine like a scanner la has a lamp seat 11a disposed therein. A lamp tube 12a used as a light source for scanning documents is disposed on the lamp seat 11a. The lamp tube 12a can be divided into single-tube type and double-tube type. A rack 13a for supporting the lamp tube 12a is disposed below the lamp tube 12a. In order to meet the compactness requirement of present products, the lamp tube 12a must be designed to be thinner. Therefore, the lamp tube 12a easily breaks because of vibration of the scanner 1a or careless fall during the transportation process.
Accordingly, the above lamp tube fixing structure has inconvenience and drawbacks in practical use. The present invention aims to resolve the problems in the prior art.
The primary object of the present invention is to provide a lamp tube support structure, which is slipped onto a lamp tube to add support positions at two ends of the lamp tube for effectively preventing breakage of the lamp tube. Moreover, clamping effect can be achieved to protect the lamp tube from impact from all directions.
To achieve the above object, the present invention provides a lamp tube support structure, which comprises mainly a support piece applying to office business machines for supporting and fixing a lamp tube thereof. The lamp tube support structure comprises a first half and a second half. The first half has a gap for placing a lamp tube. A clamping portion is formed at two extension ends of the gap. Grooves are disposed at left and right ends of the second half. A wing portion is formed below the grooves. After the wing portion is bent, it can be jammed into a hole of a rack for supporting the lamp tube so as to be erectly fixed on the rack.
