[0002] Optical fiber is a long, thin tube made of glass or plastic that can transmit a large amount of information. Fiber optic signal monitoring equipment is a device used to detect fiber optic transmission signals and can evaluate the transmission performance of the fiber optic network. Before and after the use of optical fiber, fiber optic signal monitoring equipment is generally required to measure and analyze the fiber optic transmission signal to evaluate the transmission performance of the fiber optic network. Fiber optic signal monitoring equipment can help maintenance personnel quickly locate problems in the fiber optic network to facilitate corresponding maintenance and repair.

[0003] Fiber optic signal monitoring equipment is a relatively sophisticated instrument, especially the display screen and detection socket of the equipment are generally relatively fragile. However, the display screen and detection socket of the existing fiber optic signal monitoring equipment are exposed to the outside when not in use, making the display screen and detection socket easily damaged by collision with external objects, thereby causing damage to the fiber optic signal monitoring equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a signal monitoring device for optical fiber communication equipment, so as to provide protection for a display screen and a detection socket when not in use, so as to avoid damage caused by collision with external objects.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides a signal monitoring device for optical fiber communication equipment, comprising:

[0007] A box body having an opening on one side;

[0013] The support assembly has an avoidance state and a support state. When the support assembly is in the avoidance state, the support assembly is disconnected from the signal detector so that the signal detector can move in a direction away from the box; when the support assembly is in the support state, the support assembly is connected to the signal detector so that the signal detector is fixed in the box or the signal detector is supported outside the box.

[0014] In some embodiments, a first elastic member is further included, one end of which is fixed in the box body and the other end is connected to the signal detector, and the expansion and contraction direction of the first elastic member is parallel to the moving direction of the signal detector.

[0016] In some embodiments, a fixing groove with a notch facing the side wall of the box body is opened on the side of the signal detector;

[0017] The supporting assembly includes a movable block and a driving member, wherein the movable block is arranged in the box body, and a side of the movable block facing the opening forms a supporting surface for supporting the signal detector, and the cross-sectional size of the movable block matches the fixed groove; the driving member is installed in the box body and connected to the movable block, and the driving member can drive the movable block to telescopic movement so that the movable block is inserted into the fixed groove or away from the fixed groove.

[0019] In some embodiments, the support assembly further includes a containing box fixed to a side wall of the box body, a box opening of the containing box is arranged toward the signal detector, and the movable block is movably inserted into the containing box and can extend out of the containing box.

[0020] In some embodiments, a slot is provided on the top wall of the box body, and a plug-in block matching the shape of the slot is provided on the side of the cover plate facing the box body. When the cover plate covers the opening, the plug-in block is inserted into the slot.

[0021] In some embodiments, it also includes:

[0022] A shielding component connected to a side of the signal detector where the detection socket is provided;

[0023] A shielding member is movably connected to the shielding assembly, and the shielding member has a shielding state and an open state. When the shielding member is in the shielding state, the shielding member fits and covers the detection socket; when the shielding member is in the open state, the shielding member avoids the detection socket to make the detection socket open.

When the signal detector is used, the support assembly is switched from the support state to the avoidance state by external force, so that the support assembly is disconnected from the signal detector, so that the signal detector can move in the direction away from the box. When the signal detector moves, the protection plate is driven to move, and the protection plate stops moving due to the blocking effect of the limiter during the movement process, and the signal detector continues to move until the signal detector moves to the outside of the box for detection. At this time, the support assembly is switched from the avoidance state to the support state again, and the signal detector is supported by the support assembly, so that the signal detector remains in a state fixed outside the box for optical fiber communication equipment signal monitoring.

[0032] The present application provides protection for the signal detector and its display screen and detection socket by setting up a box and a protective plate, and by setting up a supporting assembly, the signal detector can be switched between the position inside and outside the box, so that the signal detector can be moved from inside the box to outside the box for use, or moved from outside the box to inside the box for fixation, thereby preventing the signal detector from being damaged by collision with external objects due to long-term placement outside.

[0049] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0052] See also Figure 1 - Figure 7 As shown, an embodiment of the present invention provides a signal monitoring device for optical fiber communication equipment, including a box body 10, a cover plate 20, a signal detector 30, a protective plate 40, a limiter 11 and a support assembly 50, wherein one side of the box body 10 has an opening; the cover plate 20 is covered at the opening and is movably connected to the box body 10; the signal detector 30 is arranged in the box body 10 and fixed to the cover plate 20, and the signal detector 30 has a display screen 301 and a detection socket 302; the protective plate 40 is movably connected to a side of the signal detector 30 provided with the display screen 301 and the detection socket 302; the limiter 11 is fixed in the box body 10 and is located on the moving path of the protective plate 40 to stop the protective plate 40; the support assembly 50 is installed on the box body 10 and is movably connected to the signal detector 30.

[0053] The support assembly 50 has an avoidance state and a support state. When the support assembly 50 is in the avoidance state, the support assembly 50 is disconnected from the signal detector 30 so that the signal detector 30 can move away from the box 10; when the support assembly 50 is in the support state, the support assembly 50 is connected to the signal detector 30 so that the signal detector 30 is fixed in the box 10 or the signal detector 30 is supported outside the box 10.

[0054] The signal detector 30 is arranged in the housing 10, and a support assembly 50 is installed in the housing 10 and movably connected to the signal detector 30, and the support assembly 50 has an avoidance state and a support state. When the signal detector 30 is not in use, the support assembly 50 is in a support state, and the signal detector 30 is fixed in the housing 10 through the support assembly 50. The housing 10 provides protection for the signal detector 30, and the protection plate 40 provides additional protection for the display screen 301 and the detection socket 302 of the signal detector 30, so as to prevent the signal detector 30 from being damaged by collision with external objects when not in use. When the signal detector 30 is in use, the support assembly 50 is switched from the support state to the avoidance state by an external force, so that the support assembly 50 is disconnected from the signal detector 30, and the signal detector 30 can be moved away from the housing 10. When the signal detector 30 moves, it drives the protection plate 40 to move. During the movement of the protection plate 40, it stops moving due to the blocking effect of the limit member 11, and the signal detector 30 continues to move until the signal detector 30 moves to the outside of the box 10 for detection. At this time, the support assembly 50 is switched from the avoidance state to the support state again, and the support assembly 50 provides support for the signal detector 30, so that the signal detector 30 remains in a state fixed to the outside of the box 10 for signal monitoring of the optical fiber communication equipment.

[0055] The present application provides protection for the signal detector 30 and its display screen 301 and the detection socket 302 by setting up a box 10 and a protection plate 40, and by setting up a support assembly 50, the signal detector 30 can be switched between the position inside and outside the box 10, so that the signal detector 30 can be moved from inside the box 10 to outside the box 10 for use, and can also be moved from outside the box 10 to inside the box 10 for fixation, thereby preventing the signal detector 30 from being damaged by collision with external objects due to long-term placement outside.

[0056] It should be noted that, in the present application, the structure of the signal detector 30 and the detection principle of the optical fiber transmission signal are all existing technologies and will not be described in detail in the present application.

[0057] The opening of the box 10 is arranged at the top, so that the signal detector 30 moves from the top opening to the outside of the box 10. During the movement of the signal detector 30, the cover plate 20 is pushed upward, and the signal detector 30 can support the cover plate 20. Since the opening is arranged at the top of the box 10, when the cover plate 20 covers the opening, the box 10 can support the cover plate 20, thereby preventing the cover plate 20 from being disconnected from the box 10 under the action of its own gravity, and simplifying the connection structure between the cover plate 20 and the box 10. Figure 4 and Figure 6 As shown, in some embodiments, a slot 12 is provided on the top wall of the box body 10, and a plug-in block 21 matching the groove shape of the slot 12 is provided on the side of the cover plate 20 facing the box body 10. When the cover plate 20 is covered on the opening, the plug-in block 21 is inserted into the slot 12. The lateral movement of the cover plate 20 relative to the box body 10 can be limited by the cooperation between the plug-in block 21 and the slot 12, and when the cover plate 20 moves upward with the signal detector 30, the cooperation between the plug-in block 21 and the slot 12 can also play a certain guiding role in the movement of the cover plate 20. The slot 12 can be extended along the circumference of the box body 10, and the plug-in block 21 protrudes from the side of the cover plate 20 facing the box body 10 and extends along the circumference of the box body 10.

[0058] See also Figure 1 As shown, in order to facilitate the movement of the signal detector 30 in and out of the box 10, a storage groove 22 is provided on the side of the cover plate 20 facing away from the box 10, and a handle 23 is rotatably installed in the storage groove 22. When the handle 23 is not in use, the handle 23 is stored in the storage groove 22. When the handle 23 is used, the handle 23 is rotated so that the handle 23 extends from the storage groove 22. The handle 23 is U-shaped. The handle 23 facilitates the lifting or pushing of the cover plate 20, thereby facilitating the movement of the signal detector 30 in and out of the box 10.

[0059] See also Figure 2 and Figure 3As shown, in some embodiments, a fixed plate 31 is also provided on one side of the signal detector 30 where the display screen 301 and the detection socket 302 are provided, and the protective plate 40 is slidably connected to the fixed plate 31. Specifically, a sliding member 32 is slidably connected inside the fixed plate 31, and the sliding member 32 extends out of the fixed plate 31 and is fixedly connected to the protective plate 40. A fourth elastic member 33 is also provided between the sliding member 32 and the side wall of the fixed plate 31. The sliding member 32 cooperates with the fixed plate 31 to achieve the sliding connection between the protective plate 40 and the fixed plate 31. The fourth elastic member 33 is a spring. When the signal detector 30 moves out of the box 10, the signal detector 30 drives the protective plate 40 to move upward synchronously until the protective plate 40 abuts against the stopper 11. The signal detector 30 continues to move, and the protective plate 40 stops moving due to the blocking effect of the stopper 11. At this time, relative sliding occurs between the sliding member 32 and the fixed plate 31, and the fourth elastic member 33 is compressed until the support assembly 50 is supported below the signal detector 30, and the signal detector 30 stops moving. When the signal detector 30 is moved from the outside of the box body 10 to the inside of the box body 10, the fourth elastic member 33 loses the pressing effect of the fixing plate 31, and at the same time, the protection plate 40 is no longer blocked by the stopper 11. Under the elastic force of the fourth elastic member 33, the protection plate 40 is driven to reset, so that the protection plate 40 again protects the display screen 301 and the detection socket 302. The stopper 11 is a plate member, symmetrically arranged on two opposite side walls in the box body 10 to evenly block both sides of the protection plate 40.

[0060] See also Figure 4 As shown, in some embodiments, the optical fiber communication equipment signal monitoring device further includes a first elastic member 60, one end of the first elastic member 60 is fixed in the box body 10, and the other end is connected to the signal detector 30, and the extension direction of the first elastic member 60 is parallel to the moving direction of the signal detector 30. When the support assembly 50 is connected to the signal detector 30 so that the signal detector 30 is fixed in the box body 10, the signal detector 30 compresses the first elastic member 60. When the support assembly 50 is switched to the avoidance state and disconnected from the signal detector 30, the signal detector 30 moves upward under the elastic force of the first elastic member 60 until it moves to the outside of the box body 10, and then is supported at the bottom of the signal detector 30 by the support assembly 50. The first elastic member 60 enables the signal detector 30 to automatically and quickly move to the outside of the box body 10 without external interference. The first elastic member 60 is a spring.

[0061] See also Figure 4As shown, in some embodiments, the optical fiber communication equipment signal monitoring device further includes a damper 61, the damper 61 connects the box 10 and the signal detector 30, and the damping direction of the damper 61 is parallel to the moving direction of the signal detector 30. The damper 61 can buffer and reduce vibration of the movement of the signal detector 30. The damper 61 is a damping rod. When the first elastic member 60 is a spring, the first elastic member 60 is sleeved on the damper 61, and the damper 61 can also guide the elastic expansion and contraction of the first elastic member 60.

[0062] See also Figure 4 and Figure 5 As shown, in some embodiments, the side of the signal detector 30 is provided with a fixed groove 303 with a notch facing the side wall of the box body 10; the support assembly 50 includes a movable block 51 and a driving member 52, the movable block 51 is arranged in the box body 10, and the side of the movable block 51 facing the opening forms a support surface 511 for supporting the signal detector 30, and the cross-sectional size of the movable block 51 matches the fixed groove 303; the driving member 52 is installed in the box body 10 and connected to the movable block 51, and the driving member 52 can drive the movable block 51 to telescopically move, so that the movable block 51 is inserted into the fixed groove 303 or away from the fixed groove 303. When the movable block 51 is driven to be inserted into the fixed groove 303 by the driving member 52, the connection between the support assembly 50 and the signal detector 30 is realized, so that the signal detector 30 is fixed in the box body 10. When the movable block 51 is driven to be away from the fixed groove 303 by the driving member 52, the support assembly 50 is disconnected from the signal detector 30. When the signal detector 30 moves to the outside of the housing 10, the signal detector 30 is supported by the support surface 511 of the movable block 51. In order to provide a balanced support force to the signal detector 30 and to stabilize the signal detector 30 outside the housing 10, two groups of support components 50 are provided, which are symmetrically arranged on opposite sides of the signal detector 30. Specifically, corresponding fixing grooves 303 are provided on opposite sides of the signal detector 30, and each fixing groove 303 has a corresponding support component 50. The movable block 51 is plugged into the fixing groove 303 to simplify the connection structure between the support component 50 and the signal detector 30, and facilitate the telescopic driving operation of the movable block 51. In some embodiments, the cross-section of the movable block 51 is trapezoidal.

[0063] See also Figure 4 and Figure 5As shown, in some embodiments, the driving member 52 includes a handle 521 and a second elastic member 522. The handle 521 is slidably arranged on the side wall of the box body 10 and extends into the box body 10 to connect with the movable block 51. One end of the second elastic member 522 is connected to the box body 10, and the other end is connected to the movable block 51. When the handle 521 is pulled away from the box body 10, the handle 521 drives the movable block 51 to move synchronously, so that the movable block 51 close to the side wall of the box body 10 gradually disengages from the fixed groove 303, and the movable block 51 compresses the second elastic member 522. When the handle 521 is released, the movable block 51 is reset under the elastic force of the second elastic member 522, so that the movable block 51 is inserted into the fixed groove 303, or the movable block 51 is extended and supported at the bottom of the signal detector 30. The telescopic movement of the movable block 51 is driven by the cooperation of the handle 521 and the second elastic member 522, which is convenient for manual operation and enables the movable block 51 to reset automatically. Moreover, the purely mechanical structure can save energy consumption. The second elastic member 522 is a spring.

[0064] See also Figure 4 and Figure 5 As shown, in some embodiments, the support assembly 50 also includes a containing box 53, which is fixed to the side wall of the box body 10, and the box opening of the containing box 53 is arranged toward the signal detector 30, and the movable block 51 is movably inserted in the containing box 53 and can extend out of the containing box 53. The containing box 53 can support the movable block 51, and can also guide the telescopic movement of the movable block 51. The end of the second elastic member 522 can be fixed to the side wall of the containing box 53, and the handle 521 is slidably provided through the side wall of the box body 10 and the side wall of the containing box 53, and extends into the containing box 53 to connect with the movable block 51. After pulling the handle 521, the movable block 51 can move close to the containing box 53 until the movable block 51 is completely retracted into the containing box 53.

[0065] See also Figure 4 and Figure 7 As shown, in some embodiments, the optical fiber communication equipment signal monitoring device further includes a shielding component 70 and a shielding member 80, wherein the shielding component 70 is connected to a side of the signal detector 30 where the detection socket 302 is set; the shielding member 80 is movably connected to the shielding component 70, and the shielding member 80 has a shielding state and an open state. When the shielding member 80 is in the shielding state, the shielding member 80 fits and covers the detection socket 302; when the shielding member 80 is in the open state, the shielding member 80 avoids the detection socket 302 to make the detection socket 302 open. When the detection socket 302 is not in use, the detection socket 302 can be covered by the shielding member 80 to achieve dustproof treatment of the detection socket 302 and improve the service life of the detection socket 302. When the detection socket 302 needs to be used, the shielding member 80 is switched from the shielding state to the open state by external force, exposing the detection socket 302, so that the detection optical fiber can be inserted into the detection socket 302.

[0066] See also Figure 4 and Figure 7 As shown, in some embodiments, the shielding assembly 70 includes a first fixed block 71, a second fixed block 72 and a third elastic member 73, the first fixed block 71 is fixedly connected to the signal detector 30; the second fixed block 72 is fixedly connected to the signal detector 30 and is spaced apart from the first fixed block 71, and the detection socket 302 is located between the second fixed block 72 and the first fixed block 71; one end of the shielding member 80 is slidably connected to the second fixed block 72, and the other end is abutted against the first fixed block 71; one end of the third elastic member 73 is connected to the shielding member 80, and the other end is connected to the second fixed block 72; the shielding member 80 is slidable to switch the shielding member 80 between the shielding state and the open state. When the detection socket 302 is not in use, the shielding member 80 is in the shielding state and covers the detection socket 302. When the detection socket 302 is needed, slide the shielding member 80 to open the detection socket 302, insert the optical fiber into the detection socket 302, and then release the shielding member 80. The shielding member 80 resets under the elastic force of the third elastic member 73 until the shielding member 80 abuts against the optical fiber. The optical fiber can be abutted and fixed on the first fixing block 71, thereby improving the stability of the connection between the optical fiber and the detection socket 302, thereby improving the stability of monitoring the optical fiber transmission signal.

[0067] See also Figure 7 As shown, the first fixed block 71 is a block-shaped structure, and is arranged at the lower side of the detection socket 302. The second fixed block 72 is a block-shaped structure, and is arranged at the upper side of the detection socket 302. A slide groove 721 can be provided on the second fixed block 72, and a slider 81 matching the slide groove 721 is fixed on the side of the shielding member 80 facing the second fixed block 72. The slider 81 is slidably assembled in the slide groove 721 to achieve a sliding connection between the shielding member 80 and the second fixed block 72. The third elastic member 73 is fixed in the slide groove 721, one end of which is connected to the second fixed block 72, and the other end is connected to the slider 81. The slide groove 721 plays a role of accommodating the third elastic member 73. In addition, the cooperation between the slide groove 721 and the slider 81 plays a guiding role in the movement of the shielding member 80. The third elastic member 73 is a spring. The shielding member 80 is a plate-shaped structure.

[0068] See also Figure 7 As shown, in order to facilitate the moving operation of the shielding member 80, an operating plate 82 is fixed to the side of the shielding member 80 away from the detection socket 302. By pulling the operating plate 82, the shielding member 80 moves upward to expose the detection socket 302. At the same time, the third elastic member 73 is compressed during the upward movement of the shielding member 80. When the operating plate 82 is released, the shielding member 80 performs a downward reset movement under the elastic action of the third elastic member 73.

[0069] In order to facilitate the support of the optical fiber in the detection socket 302, the first fixing block 71 protrudes outward from the detection socket 302 on the side away from the signal detector 30. The protruding portion can be used to support the optical fiber in the detection socket 302. Combined with the abutment effect of the shielding member 80, the optical fiber can be stably inserted in the detection socket 302.

[0070] The working process of the present invention is:

[0071] When the signal detector 30 is not in use, the signal detector 30 is placed in the box 10 and is protected by the box 10 .

[0072] When the signal detector 30 is needed, the handle 521 is pulled away from the box 10, and the movable block 51 is driven to move to the outside of the fixed groove 303 by the handle 521, until the movable block 51 is retracted into the inside of the accommodating box 53. At this time, the second elastic member 522 is contracted, and the first elastic member and the damping rod in the contracted state are reset, and the signal detector 30 is driven to rise slowly, so that the signal detector 30 moves to the outside of the box 10, and the cover plate 20 is driven to move, so that the plug-in block 21 moves to the outside of the slot 12. At the same time, the signal detector 30 drives the protection plate 40 to move while moving. Since the limiter 11 is on the motion trajectory of the protection plate 40, the protection plate 40 resists the limiter 11 when moving, and the signal detector 30 continues to move to the outside of the box 10. The protection plate 40 no longer moves, and relative sliding occurs between the sliding member 32 and the fixed plate 31. At this time, the fourth elastic member 33 is contracted.

[0073] When the detection socket 302 moves to the outside of the box 10 along with the signal detector 30, the handle 521 can be released, and the second elastic member 522 in the contracted state is reset, and at the same time, the movable block 51 is reset, so that the movable block 51 moves to the bottom of the signal detector 30. At this time, the signal detector 30 can be supported by the supporting surface 511 of the movable block 51, and then the signal detector 30 can be used.

[0074] When it is necessary to insert the optical fiber into the detection socket 302 for monitoring, the shielding member 80 can be pulled through the operating panel 82, so that the shielding member 80 moves along the slide groove 721 through the slider 81 in the direction away from the first fixed block 71. At this time, the third elastic member 73 contracts until the slider 81 slides to the other end of the slide groove 721. At this time, the detection socket 302 can be exposed, and the optical fiber can be inserted into the detection socket 302 for monitoring. Then the operating panel 82 can be released, and the third elastic member 73 in the contracted state is reset. At the same time, the shielding member 80 is reset by the slider 81. The shielding member 80 can be fixed to the optical fiber through the force generated by the reset of the third elastic member 73, so that the optical fiber is inserted into the detection socket 302 for monitoring more stably, thereby avoiding the shaking of the optical fiber and affecting the monitoring effect.

[0075] When the optical fiber detection is completed, the optical fiber can be pulled out. When the optical fiber is pulled out to the outside of the detection socket 302, the third elastic member 73 which is in a contracted state continues to reset until the end of the shielding member 80 close to the first fixed block 71 is in contact with the first fixed block 71. At the same time, the shielding member 80 is in contact with the surface of the detection socket 302, so that the detection socket 302 can be protected from dust.

[0076] Then, pull the handle 521 to move the movable block 51 toward the side wall of the box 10, so that the movable block 51 no longer supports the signal detector 30. At this time, the cover plate 20 and the signal detector 30 are pushed toward the inside of the box 10 by lifting the handle 23 to overcome the elastic force of the first elastic member 60, until the plug-in block 21 is moved into the slot 12, so that the cover plate 20 and the top of the box 10 fit together, and the fixed slot 303 corresponds to the position of the movable block 51. Release the handle 521, the movable block 51 is reset, and the movable block 51 is inserted into the fixed slot 303 to fix the signal detector 30. At the same time, the protective plate 40 is no longer squeezed by the limit member 11, and the fourth elastic member 33 in the contracted state is reset, and the protective plate 40 is driven to reset at the same time, so that the box 10 and the protective plate 40 can protect the signal detector 30 again after use.

[0077] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
