Detailed Description
The invention is further described with reference to the following figures and examples.
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following description will be made with reference to fig. 1 to 6 of the embodiments of the present invention to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
Each reference numeral in fig. 1 to 6 denotes:
1. a rubber sealing sleeve; 2. a tightening sleeve; 3. an elastic sealing gasket; 4. a rain cover; 5. a bolt; 6. a first rubber filling block; 7. a second rubber filling block; 8. a strip-shaped groove; 21. the lower section of the sleeve is tightened; 22. the upper section of the sleeve is tightly hooped; 23. an internal thread; 41. the lower section of the rain cover; 42. a middle section of a rain cover; 43 rain cover upper end.
The first embodiment is as follows:
the general rain-proof cap of optical cable protective pipe as shown in fig. 1 comprises a rubber sealing sleeve 1, a hooping sleeve 2, an elastic sealing gasket 3, a rain-proof cover 4 and a rubber filling block. As shown in fig. 2, the rubber sealing sleeve 1 is cylindrical and made of styrene butadiene rubber; as shown in fig. 3, the lower end 21 of the tightening sleeve is a sleeve with internal threads 23, and the upper end 22 of the tightening sleeve is a circular ring-shaped first flange. During installation, the rubber sealing sleeve 1 is sleeved on the optical cable protective pipe, the tightening sleeve 2 is sleeved on the rubber sealing sleeve 1 in a screwing mode, and the rubber sealing sleeve 1 is folded towards the center under the extrusion of the internal thread 23 and tightly wraps the optical cable protective pipe.
