[0030] EMBODIMENT

[0031] EMBODIMENT ONE

[0032] As​​Figure 2 and Figure 3 As shown in

[0033] As shown in Figure 3 and Figure 6 One end of the shell 1 is provided with a cleaning port 2, one end of the rack 6 is sleeved with a connecting piece 8 which is in sliding fit with the inner wall of the cleaning port 2, one end of the connecting piece 8 is installed in the connector 17 of the fiber end face, the connecting piece 8 can be installed in the connector 17 of the fiber end face by the way of insertion, which is convenient to operate. The other end of the rack 6 is in meshing connection with the gear 5, one end of the rack 6 penetrates through the connecting piece 8 and extends into the connector 17, the model of the gear 5 and the rack 6 is not limited here, which can meet the actual use requirements.

[0034] The two ends of the cleaning belt 7 are wound on the take-up reel 3 and the pay-off reel 4 respectively, the middle part of the cleaning belt 7 passes through one end of the rack 6 and contacts with the fiber end face in the connector 17. The material of the cleaning belt 7 is high-density textile fiber, the cleaning belt made of this material can effectively remove dust, oil stains and other small impurities on the fiber end face, and will not cause damage to the fiber end face.

[0035] By slidingly installing the connecting piece 8 in the cleaning port 2, the user can quickly drive the rack 6 to elastically slide when pushing the connecting piece 8, the rack 6 drives the gear 5 in meshing connection therewith to rotate, the take-up reel 3 in coaxial connection therewith rotates to wind the cleaning belt 7 around one end of the rack 6, the position of the cleaning belt 7 contacting with the fiber end face moves constantly, and then the fiber end face of the connector 17 is wiped by the moving cleaning belt 7, which effectively removes dust, oil stains and other small impurities on the fiber end face.

[0036] As shown in Figure 4 and Figure 6As shown, the rack 6 comprises a guide rod 9 and a connecting rod 10, the guide rod 9 is in sliding fit with the inner wall of the shell 1, one end of the guide rod 9 is connected with the connecting rod 10, and the other end is the rack end engaged with the gear 5, one end of the connecting rod 10 penetrates through the connecting piece 8 and extends into the connector 17, the middle part of the cleaning tape 7 passes around one end of the connecting rod 10 and contacts with the fiber end face in the connector 17. The other end of the connecting rod 10 is provided with a first compression spring 11 sleeved on the other end of the guide rod 9, one end of the first compression spring 11 abuts against the inner wall of the shell 1, and the other end abuts against the connecting rod 10. By providing the guide rod 9 on the rack and sleeving the first compression spring 11 on the guide rod 9, the elastic sliding of the rack 6 in the shell 1 is realized. The connecting rod 10 is arranged to assemble and connect the rack 6 with the guide rod 9 to the connecting piece 8.

[0037] In use, the connecting piece 8 is first inserted into the connector 17, and then the connector 17 is moved transversely to move the connecting piece 8 transversely along the cleaning port 2, at this time, the connecting rod 10 mounted on the connecting piece 8 also moves, and the guide rod 9 on the connecting rod 10 moves transversely along the inner wall of the shell 1, and finally the rack 6 on the guide rod 9 moves transversely, at this time, the first compression spring 11 is compressed. The transverse movement of the rack 6 drives the gear 5 engaged with the rack 6 to rotate, and the take-up reel 3 coaxially connected with the gear 5 rotates to wind the cleaning tape 7 on the releasing reel 4, and the inner wall of the connector 17 in which the fiber end face mounted on the connecting piece 8 is cleaned in the winding process of the cleaning tape 7. The distance of the winding movement of the cleaning tape 7 depends on the distance of the movement of the connecting piece 8 in the cleaning port 2.

[0038] After the cleaning work is completed, the first compression spring 11 loses the support of external force, drives the rack 6 to move to the direction of the cleaning port 2 and restores to the original position, and the rack 6 drives the gear 5 to rotate reversely, but since the shaft coaxially connected with the gear 5 is rotatably mounted on the shell 1 through a one-way bearing, the shaft does not rotate when the shaft rotates, so the take-up reel 3 does not rotate, which can ensure that the cleaning tape 7 can only be gradually wound on the take-up reel 3, and the repeated use of the used cleaning tape 7 is prevented.

[0039] In the specific implementation process, it is particularly worth pointing out that: when the use scene is that the connector 17 of the fiber end face cannot be moved, the connecting piece 8 is first inserted into the connector 17, and then the shell 1 is pushed to move to the connector 17, that is, the shell 1 moves transversely along the connecting piece 8, at this time, the rack 6 moves relative to the shell 1, the rack 6 is engaged with the gear 5, the gear 5 rotates to drive the take-up reel 3 coaxially connected with the gear 5 to rotate, and the cleaning tape 7 on the releasing reel 4 is wound, and the fiber end face in the connector 17 is cleaned in the winding process of the cleaning tape 7.

[0040] As shown in the drawings, Figure 3 and Figure 6As shown, the outer wall of the housing 1 on both sides of the rack 6 is respectively provided with a first guide column 14 and a second guide column 15 for guiding the cleaning belt 7 to pass the end of the connecting rod 10 back to the take-up reel 3. As shown Figure 3 As shown, the first guide column 14 is arranged above the rack 6, and the second guide column 15 is arranged below the rack 6. The cleaning belt 7 coming out of the take-up reel 4 can be wound on the take-up reel 3 after passing the first guide column 14, one end of the connecting rod 10 and the second guide column 15 in turn. Through the guidance of the first guide column 14 and the second guide column 15, the cleaning belt 7 moves stably in the housing 1. That is, it ensures that the cleaning belt 7 moves along the predetermined path and prevents the cleaning belt 7 from deviating from the track or winding.

[0041] As shown Figure 1 As shown, the housing 1 includes a lower housing 101 and an upper housing 102, and the lower housing 101 is sealingly engaged with the upper housing 102. By dividing the housing 1 into two upper and lower housings, the user can easily assemble the structure by a simple connection method such as a bolt, and then facilitate the maintenance and replacement of the internal parts or the cleaning belt as a consumable. And the lower housing 101 and the upper housing 102 are sealingly engaged, which ensures the sealing and prevents external dust and impurities from entering and contaminating the cleaning belt.

[0042] Example two

[0043] This embodiment is based on the above-mentioned embodiment one, the connecting rod 10 is divided into a fixed connecting rod 18 and a movable connecting rod 12, and the movable connecting rod 12 can elastically slide in the inner wall of the fixed connecting rod 18, but cannot be separated from the fixed connecting rod 18, and the rest is the same as the structure of embodiment one.

[0044] As shown Figure 4 And Figure 5 As shown, the connecting rod 10 includes a fixed connecting rod 18 and a movable connecting rod 12, one end of the fixed connecting rod 18 is connected with the movable connecting rod 12, and the other end is connected with the guide rod 9. A groove for loading the silica gel cleaning pad 16 is formed in one end of the movable connecting rod 12, and the middle part of the cleaning belt 7 passes around one end of the movable connecting rod 12 and contacts with the silica gel cleaning pad 16. The silica gel cleaning pad 16 is soft in material, which can avoid the cleaning belt 7 from being broken during wiping as much as possible.

[0045] The other end of the movable connecting rod 12 is in sliding fit with the inner wall of the connecting piece 8, and the other end of the movable connecting rod 12 is in sliding fit with the inner wall of the fixed connecting rod 18. A second compression spring 13 is sleeved on the movable connecting rod 12, one end of the second compression spring 13 abuts against the other end of the movable connecting rod 12, and the other end of the second compression spring 13 abuts against the inner wall of the fixed connecting rod 18. The other end of the movable connecting rod 12 is provided with a limiting piece for preventing the movable connecting rod 12 from separating from the fixed connecting rod 18.

[0046] During the process that the connecting piece 8 is inserted into the connector 17 of the fiber end face, the movable connecting rod 12 slides to the inner wall of the fixed connecting rod 18 under the pushing of the inner wall of the connector 17, and at this time, the second compression spring 13 is elastically deformed under the action of external force. The second compression spring 13 makes the movable connecting rod 12 obtain a force of naturally sliding outwards of the connecting piece 8, and further drives the silica gel cleaning pad 16 to extend outwards of the connecting piece 8 as far as possible, so that the cleaning belt 7 at the silica gel cleaning pad 16 can be more closely contacted with the fiber end face in the connector 17, and the cleaning belt 7 can better clean the dust, impurities or oil stains on the fiber end face in the connector 17 during the process of winding movement. And due to the setting of the limiting piece, the movable connecting rod 12 will not be separated from the inner wall of the fixed connecting rod 18 under the elastic action of the second compression spring 13 when sliding to the inner wall of the fixed connecting rod 18.

[0047] The fixed connecting rod 18 is internally provided with a long strip sliding cavity 19 extending along the length direction thereof, that is, the long strip sliding cavity 19 is consistent with the moving direction of the movable connecting rod 12 along the inner wall of the fixed connecting rod 18. The long strip sliding cavity 19 is provided with a first through hole 20 at one end close to the movable connecting rod 12, and the inner diameter of the first through hole 20 is smaller than the inner diameter or width of the long strip sliding cavity 19, so as to facilitate the subsequent limiting piece to be clamped in the long strip sliding cavity 19 through the first through hole 20. One end of the second compression spring 13 is in abutment with the other end of the movable connecting rod 12, and the other end is in abutment with the hole wall of the first through hole 20.

[0048] The limiting piece comprises two elastic rods 21 which are parallelly arranged and fixed at one end of the movable connecting rod 12, and the two elastic rods 21 are two parts formed by cutting grooves in the middle of a cylinder, and the diameter of the cylinder is not greater than the inner diameter of the first through hole 20, so as to facilitate the better sliding of the two elastic rods 21 into the long strip sliding cavity 19, and realize the relative sliding between the movable connecting rod 12 and the fixed connecting rod 18. One end of each of the two elastic rods 21 close to the fixed connecting rod 18 is provided with a clamping head 22 protruding to one side away from each other, and the protrusion is preferably in the form of an inclined surface, so as to facilitate the two clamping heads 22 to more smoothly pass through the first through hole 20 and then expand to be clamped at one end of the long strip sliding cavity 19, and the long strip sliding cavity 19 is used for accommodating the clamping head 22. At the same time, the length of the clamping head 22 is smaller than the length of the long strip sliding cavity 19, so that the clamping head 22 has a space for sliding in the long strip sliding cavity 19, and thus the relative sliding between the movable connecting rod 12 and the fixed connecting rod 18 can be realized.

[0049] The above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
