Example 2
The applicant finds that the buckle 11 and the clamping groove 10 are arranged to close the protective cover 5 in a clamping manner, and after the protective cover is used for a long time, the buckle 11 or the clamping groove 10 is worn, deformed or even damaged, and the clamping is not tight enough, so that the protective cover 5 cannot be closed and loses the protective effect on the connecting joint 2 and the anti-falling device 4; secondly, after the tester is used and the protective cover 5 is closed, although the protective cover 5 has a certain protective effect on the connecting joint 2, when the tester is used in some dust and humid environments, on one hand, a special cleaning tool needs to be additionally prepared, and the optical port in the connecting joint 2 needs to be cleaned, so that the problem that the noise of the tester is increased and the curve is poor is avoided, and thus, the special cleaning tool needs to be prepared, which is very inconvenient; on the other hand, after the tester is used up, the test optical cable joint is taken down, after the protective cover 5 is closed, the optical port on the butt joint 2 is not protected, dust and water vapor in the protective cover 5 can still pollute the optical port of the connection joint 2, so that the optical port of the butt joint 2 must be cleaned before the tester is used next time, and the workload is increased; for this reason, the applicant has further developed the anti-drop device 4 and the protective cover 5.
As shown in fig. 5-7, through slots 17 are formed in two sides of the protective cover 5, the protective cover 5 is closed, the crank 13 connected with the button 16 passes through the through slots 17, the elastic block on the inner wall of the button 16 is tightly attached to the outer wall of the protective cover 5, the sealing block 25 is arranged on the crank 13 connected with the button 16, the protective cover 5 is closed, the elastic block on the inner wall of the button 16 and the sealing block 25 seal two sides of the through slots 17, on one hand, external dust or water vapor can be prevented from entering the protective cover 5 after sealing, the anti-falling device, the connecting joint 2, the optical port and the like in the protective cover 5 can be protected, and on the other hand, when the protective cover 5 is opened by pressing the button 16, the elastic block on the inner wall of the;
a fixed block 18 is arranged on the inner wall of the top of the protective cover 5, the fixed block 18 is in threaded connection with an upper connecting rod 19, the upper connecting rod 19 can be detached from the fixed block 18, and an elastic air bag 20, a lower connecting rod 21, a connecting block 22 and a cleaning block 23 which are connected by holding the upper connecting rod 19 by hand can be used for automatically cleaning places needing to be cleaned; a cylindrical elastic air bag 20 is connected below the upper connecting rod 19, and the distance between the two clamping blocks 14 is smaller than the diameter of the elastic air bag 20 under the natural state of the return spring 15, so that after the protective cover 5 is closed to enable the elastic air bag 20 to be clamped between the two clamping blocks 14, the two clamping blocks 14 can extrude the elastic air bag 20, and on one hand, cleaning liquid in the elastic air bag 20 is squeezed out to clean an optical port of the connecting joint 2; on the other hand, after the protective cover 5 is closed, the two clamping blocks 14 clamp the elastic air bag 20, and the elastic air bag 20 pulls the protective cover through the upper connecting rod 19 and the fixing block 18, so that the problem that after long-time use, the buckle 11 or the clamping groove 10 is worn, deformed or even damaged, the clamping connection between the buckle 11 and the clamping groove 10 is not tight enough, the protective cover 5 cannot be closed, and the protective effect on the connecting joint 2 and the anti-falling device 4 is lost is solved.
The elastic air bag 20 is filled with cleaning fluid which is formed by mixing alcohol and ether and is used for cleaning the light opening on the connecting joint 2; the elastic air bag 20 is provided with a lower connecting rod 21 below, the lower end of the lower connecting rod 21 is provided with a connecting block 22, a cleaning block 23 is arranged below the connecting block 22, the connecting block 22 is movably connected with the lower connecting rod 21 through threads, and the connecting block 22 is bonded with the cleaning block 23 made of absorbent cotton. On one hand, the connecting block 22 and the cleaning block 23 can be detached from the lower connecting rod 21, and the cleaning block 23 can be replaced after being polluted; on the other hand, after the connecting block 22 is removed, the end part of the suction pipe 24 is exposed, and the elastic air bag 20 is squeezed to suck new cleaning liquid into the elastic air bag 20; meanwhile, the absorbent cotton has good water absorption and can uniformly absorb the cleaning solution to clean the optical port of the connecting joint 2.
The lower connecting rod 21 is a hollow rod and is internally provided with a suction pipe 24, one end of the suction pipe 24 is communicated with the inside of the elastic air bag 20, and the other end of the suction pipe 24 penetrates through the connecting block 22 and is contacted with the cleaning block 23; the opening of the contact end of the suction pipe 24 and the cleaning block 23 is very small, and as the principle of a laboratory suction pipe is consistent, on one hand, the effect that the elastic air bag 20 is extruded, the cleaning liquid flows out of the elastic air bag 20, and when the elastic air bag 20 is not extruded, the cleaning liquid in the elastic air bag 20 cannot flow out can be achieved; on the other hand, the extruded cleaning liquid is prevented from dropping beyond the saturation of the cleaning block due to excessive amount, so that the influence on internal components is avoided; the cleaning block 23 and the connecting block 22 are provided with end covers which are fixedly connected with the lower connecting rod 21 through connecting ropes. When the protective cover 5 is opened and the anti-dropping device is used, in order to prevent the connecting block 23 and the cleaning block 23 from being polluted by dust and water vapor in the environment, the connecting block 23 and the cleaning block 23 can be covered by end covers and opened when needed.
After the measuring instrument is used, the protective cover 5 is closed, the button 16 is simultaneously squeezed, the crank 13 is used for poking the two clamping blocks 14 to be opened, the return spring 15 is compressed, the distance between the two clamping blocks 14 is increased, the elastic air bag 20 is clamped between the two clamping blocks 14, the cleaning block 23 is simultaneously squeezed to be in contact with the connecting joint 2, the button 16 is loosened, the return spring 15 is reset, the two clamping blocks 14 squeeze the elastic air bag 20, cleaning liquid in the elastic air bag 20 reaches the cleaning block 23 through the suction pipe 24 and is absorbed by the cleaning block 23, and as the cleaning block 23 is squeezed to be in contact with the connecting joint 2, an optical port on the connecting joint 2 can be cleaned; after closing the protective cover, the light opening on the connecting joint 2 can be further cleaned by pulling the button 16 outward separately or simultaneously, so that the crank 13 stretches the return spring 15 and the two clamping blocks 14 press the elastic airbag 20, and the cleaning liquid is squeezed onto the cleaning block 23.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
