[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1-3 The embodiment of the utility model provides an indoor optical cable quality detection device, including a main body 1 and an optical connector 2 arranged on the main body 1, the main body 1 is configured with an inclined groove 3, a protective cover 4 is slidably connected in the inclined groove 3, and the protective cover 4 is configured with a groove 5.

[0026] Specifically, an optical cable is a telecommunication transmission line for transmitting optical signals, usually composed of one or more optical fibers, and one or more optical fibers are wrapped with a protective layer; an optical power meter is an instrument used to measure absolute optical power or the relative loss of optical power through a section of optical fiber. After the optical cable is installed, a connector structure is generally provided at its end, and the optical connector 2 is connected to the connector structure at the end of the optical cable. After the optical connector 2 is connected to the end of the optical cable, the relative loss of optical power of the section of optical fiber can be measured by the optical power meter. The above are all existing technologies and will not be repeated. The innovation of the embodiment of the utility model is that the protective cover 4 can move along the inclined groove 3 to approach or move away from the main body 1. When the protective cover 4 is close to the main body 1, the optical connector 2 is covered to avoid a large amount of dirt accumulating in the optical connector 2 as much as possible; when the protective cover 4 is away from the main body 1, the optical connector 2 can be exposed through the groove 5 to connect the optical cable and perform measurement; when connecting the optical cable, the protective cover 4 can approach the main body 1 again to contact and squeeze the end of the optical fiber through the groove 5 (the connector structure of the optical cable generally protrudes from the main body 1 of the optical cable, and the protective cover 4 can contact the connector structure through the inner wall of the groove 5 when it approaches the main body 1) to force the optical fiber end to be closer to the optical connector 2, thereby improving the stability of the connection between the optical connector 2 and the optical fiber end, and further improving the accuracy of detection.

[0027] The indoor optical cable quality detection device provided by the embodiment of the utility model can protect the optical connector 2 by arranging the protective cover 4, so as to avoid the accumulation of dirt in the optical connector 2 when the main body 1 is idle; when the optical connector 2 is in use, the protective cover 4 moves away from the main body 1 along the inclined groove 3 to allow the optical connector 2 to be exposed to connect the optical cable; after the optical connector 2 is connected to the optical cable, the protective cover 4 moves close to the main body 1 along the inclined groove 3 to squeeze the optical cable end through the groove 5, so as to force the optical cable end to be firmly connected to the optical connector 2.

[0028] In another embodiment provided by the utility model, further, one end of the inclined groove 3 close to the protective cover 4 is closer to the optical connector 2. Specifically, a connecting portion 11 is constructed on one side of the protective cover 4, and a connecting block is constructed on the inner wall of the connecting portion 11. The connecting block is slidably connected in the inclined groove 3, so that the protective cover 4 moves along the inclined groove 3 through the connecting block; the optical connector 2 is arranged at the top of the main body 1, and the protective cover 4 is arranged at the top of the optical connector 2. When the protective cover 4 moves upward along the inclined groove 3, the protective cover 4 will move to the side away from the center of the main body 1 while moving upward, so as to leak the optical connector 2 and drive the groove 5 away from the center of the main body 1, so as to facilitate the connection between the optical connector 2 and the optical cable end; after the optical cable end is connected to the position of the optical connector 2, the protective cover 4 moves down along the inclined groove 3 and drives the groove 5 close to the center of the main body 1, so as to resist the connector structure of the optical cable through the inner wall of the groove 5, thereby forcing the optical cable to be firmly connected to the optical connector 2.

[0029] Preferably, two protective covers 4 are provided. Specifically, a single protective cover 4 can cover the optical connector 2 or allow the optical connector 2 to be exposed, but the area of ​​the protective cover 4 required is relatively large. Therefore, a protective cover 4 is provided on both sides of the main body 1, so that the optical connector 2 can be covered or allowed to be exposed by the two protective covers 4, thereby reducing the area of ​​the protective cover 4 and its moving distance; it should be noted that the two protective covers 4 are staggered, and when the two protective covers 4 cover the optical connector 2, the two protective covers 4 cross-fit on the optical connector 2, and the grooves 5 of the two protective covers 4 are just staggered (such as Figure 1 As shown), try to avoid leakage of the optical connector 2.

[0030] Furthermore, two inclined grooves 3 are constructed on both sides of the main body 1, and two protective covers 4 are respectively slidably connected in the two inclined grooves 3. Specifically, the thickness of the main body 1 is limited, and the two inclined grooves 3 cannot be set on the same side of the main body 1 at the same time, which will increase the thickness of the main body 1. For this reason, the two inclined grooves 3 are respectively constructed on both sides of the main body 1, so that the two protective covers 4 are respectively slidably connected in the two inclined grooves 3, that is, the two protective covers 4 are respectively slidably connected on both sides of the main body 1; it should be noted that for the perspective view of the main body 1, from the side of the main body 1 with the inclined grooves 3, the two inclined grooves 3 cross to form an "X" shape, so that the two protective covers 4 can be guided to approach each other when approaching the optical connector 2, and to move away from each other when moving away from the optical connector 2.

[0031] Furthermore, when the two protective covers 4 are away from the main body 1, the two grooves 5 allow the optical connector 2 to leak out. The two protective covers 4 move synchronously along the two inclined grooves 3. Specifically, when the two protective covers 4 are synchronously close to the main body 1, the two protective covers 4 approach each other and approach the side of the optical connector 2 until the two protective covers 4 cover the optical connector 2 in an interlaced manner to protect the optical connector 2 (such as Figure 1When the two protective covers 4 are synchronously away from the main body 1, the two protective covers 4 move away from each other and move toward the side away from the optical connector 2 to leak out the optical connector 2 through the two grooves 5 (as shown); Figure 2 After the optical cable is connected to the optical connector 2, the two protective covers 4 are synchronously driven close to the main body 1, so that the two grooves 5 can be close to each other and close to the side of the optical connector 2, so that the inner walls of the two grooves 5 can resist the connector structure of the optical cable, thereby forcing the optical cable end to be firmly connected to the optical connector 2.

[0032] Preferably, a moving ring 6 is sleeved on the main body 1, and two through grooves 7 are symmetrically constructed on the moving ring 6. Both of the two protective covers 4 are constructed with protruding blocks 8, and the two protruding blocks 8 are respectively located in the two through grooves 7. Specifically, the inner wall of the moving ring 6 fits with the outer wall of the main body 1, and the moving ring 6 can move along the length of the main body 1. During the movement of the moving ring 6, the protruding blocks 8 and the protective cover 4 can be forced to move through the inner wall of the through groove 7, so that the protective cover 4 can be driven to move along the inclined groove 3. Correspondingly, during the movement of the protective cover 4 along the inclined groove 3, the protruding blocks 8 move relatively in the through groove 7; the effect of such a setting is that the movement of a single moving ring 6 along the length of the main body 1 can drive the two protective covers 4 to move synchronously along the corresponding inclined groove 3, thereby synchronously driving the two protective covers 4 to approach or move away from the main body 1, and then driving the two protective covers 4 to cover the optical connector 2 or leak the optical connector 2.

[0033] Preferably, a slide groove 9 is configured on the main body 1, and the moving ring 6 is slidably connected in the slide groove 9. Specifically, the slide groove 9 is configured along the length direction of the main body 1, so that the moving ring 6 can move along the length direction of the main body 1 through the slide groove 9, and then the two protective covers 4 are synchronously driven to move through the moving ring 6.

[0034] Furthermore, an elastic member 10 is provided between the main body 1 and the movable ring 6 . Specifically, the elastic member 10 is arranged on the side of the moving ring 6 away from the protective cover 4 and the elastic member 10 is in a stretched state. The elastic member 10 can select a structure such as an elastic telescopic rod in the prior art. Preferably, the elastic member 10 is a spring arranged in the slide groove 9, and the two ends of the spring are respectively fixed on the inner wall and the outer wall of the moving ring 6; the moving ring 6 can be stretched by the elastic member 10 to move to the side away from the protective cover 4, so that the two protective covers 4 can be driven by the moving ring 6 to synchronously approach the main body 1, thereby forcing the two protective covers 4 to cover and protect the optical connector 2 through the elastic member 10; conversely, when the optical connector 2 is leaked out when needed, the moving ring 6 can be pushed to one side of the protective cover 4, so that the moving ring 6 overcomes the elastic force of the elastic member 10 and drives the two protective covers 4 to synchronously move away from the main body 1, thereby leaking the optical connector 2 to connect the optical cable end; accordingly, after the optical cable is connected to the position of the optical connector 2, loosening the moving ring 6 can enable the elastic member 10 to drive the moving ring 6 away from the protective cover 4, thereby synchronously driving the two grooves 5 to resist the optical cable end, thereby improving the stability of the connection between the optical cable and the optical connector 2.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
