Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-4, a combined optical fiber collimator, including the main casing body 8, the middle part internal surface of the main casing body 8 is provided with the optical fiber bundle 7, the surface of one side of the main casing body 8 is provided with a protective wire section of thick bamboo 2, the surface of the protective wire section of thick bamboo 2 has been seted up and has been buffered 1, one side of the protective wire section of thick bamboo 2 is provided with assist drive device 3, assist drive device 3's surface has been seted up and has been retracted groove 9, the inside that retracts groove 9 is provided with folding the support 10, retract and be provided with loose axle 4 between groove 9 and the folding support 10, one side of assist drive device 3 is provided with lag 11, one side surface of lag 11 is provided with chassis 5, be provided with threaded zone 6 between chassis.

The inner surface of the protective sleeve 11 is movably connected with the outer surface of the main shell 8 through the threaded area 6, so that the protective position can be conveniently adjusted; the number of the buffer grooves 1 is a plurality of groups, which is beneficial to the movement in a certain range; the outer surface of one side of the folding support 10 is movably connected with the inner surface of one side of the retraction groove 9 through the movable shaft 4, and the number of the folding support 10 and the number of the retraction groove 9 are two, so that the folding support is convenient to assemble and disassemble in a labor-saving manner; the outer surfaces of the folding support 10 and the protecting sleeve 11 are both provided with anti-skid threads, so that better gripping is facilitated; the fiber core is arranged inside the optical fiber bundle 7, and the protective layer and the cavity are arranged inside the main shell 8, so that better connection is facilitated.

It should be noted that, the present invention is a combined optical fiber collimator, which needs to connect the whole device with the optical fiber bundle 7 before use, so as to be able to perform the conversion of the transmission light into the collimated light (parallel light) at the end, or couple the external parallel (approximately parallel) light into the single-mode optical fiber, and in the actual use process, it needs to connect the main housing 8 with other devices, but the conventional structure lacks a certain protection effect on the connection portion, which leads to the easy damage caused by twisting in the use process, and this problem can be improved by the protecting sleeve 11, the main housing 8 is normally connected in the actual operation, and then the protecting sleeve 11 is rotated and adjusted with the threaded area 6 through the chassis 5, so that the protecting sleeve 11 can play an effective isolation and protection role at the connection portion, and the rubber ring 12 can better contact with the planar structure, therefore, the protection effect is more ideal, besides the connection part of the collimator and the equipment needs to be protected, the leading-in end of the optical fiber bundle 7 is very fragile, but the protection effect of the existing similar products on the connection part is relatively poor, the problem can be improved through the wire protecting cylinder 2, compared with the structure that the traditional optical fiber bundle 7 is directly led into contact with the main shell 8, the wire protecting cylinder 2 can lead the introduced buffer distance to be longer, so that when the optical fiber bundle 7 is twisted under the influence of external force, the normal twisting range of the optical fiber bundle 7 can be ensured by the buffer groove 1, but when the wire protecting cylinder 2 is combined with the buffer groove 1, the twisting range and the twisting friction can be better reduced, the optical fiber bundle 7 is better prevented from being damaged by the twisting friction, the actual service life of the optical fiber bundle 7 is longer, and the whole volume of the collimator is smaller due to the actual use requirement, therefore, the disassembly and assembly are difficult, the problem can be solved through the power assisting mechanism 3, the folding support 10 can be erected in the retraction groove 9 through the movable shaft 4 in the actual disassembly and assembly, the moment can be longer to achieve the purpose of labor saving when the main shell body 8 is rotated after the operation, the folding support 10 can be retracted into the retraction groove 9 again after the text operation, the blocking effect caused by the convex structure is avoided, and the whole operation is simple, fast and practical.
