Detailed Description

In order to make the technical means, the original characteristics, the achieved purpose and the efficacy of the utility model easy to understand, the utility model is further described with reference to the specific drawings.

As shown in fig. 1, an optical module with a good dustproof effect comprises an optical module body, wherein protective sleeves are sleeved on the top, the bottom and two ends of the optical module body together, one side of each protective sleeve is further communicated with a corrugated pipe 2 used for sleeving the end part of the optical module body, a lantern ring 1 is further sleeved on each corrugated pipe 2, the top of each protective sleeve is further communicated with an inflation tube 8, and the bottom of each inflation tube 8 is communicated with the inside of each protective sleeve.

The protective sheath includes two diaphragms 4, arc portion 3, and one side both ends of arc portion 3 are connected with the tip of two diaphragms 4 respectively, are equipped with through-hole 5 on the arc portion 3, and the inner channel on the bellows 2 is linked together through-hole 5 and arc portion 3, is connected with hasp 7 on wherein the other end of a diaphragm 4, the detachable fixed connection in bottom of the other end of hasp 7 and another diaphragm 4.

The bottom of the gas-filled tube 8 is communicated with one of the transverse plates.

The two side walls of one transverse plate 4 are respectively hinged with a fixing plate, each fixing plate is fixedly installed on the side wall of the other transverse plate through screws, and the fixing plates corresponding to the two transverse plates 4 are provided with sealing strips.
