[0015] Compared with the prior art, the present invention provides an infrared induction intelligent monitoring device for a wiring rack, which has the following beneficial effects: 1. The infrared induction intelligent monitoring device for the wiring rack monitors the insertion situation of the cable at the connection port through the infrared monitoring module. The setting of the baffle prevents dust from entering when the connection port is not in use, which may cause the infrared monitoring module to be covered with dust, ensuring the accuracy of the infrared monitoring results. 2. When the cable is inserted into the connection port, the baffle of the infrared induction intelligent monitoring device for the wiring rack is folded and placed flat in the storage shell, avoiding the baffle occupying too much area on the left and right sides or the upper and lower sides, thereby reducing the space occupied by the wiring rack. 3. When the cable is inserted into the connection port or pulled out from the connection port, the movement of the storage component can drive the dust removal component to move, enabling the dust removal component to discharge air from the inside of the connection port to the outside when the baffle is stored or reset, preventing dust from drifting into the connection port and ensuring the insertion and use effect of the connection port. 4. After the cable connector is inserted into the connection port, the cable connector applies a thrust to the extrusion inclined surface of the limiting block, causing the limiting block to move downward and be inserted into the limiting groove of the baffle to limit the baffle. The limiting block always applies an upward thrust to the cable connector under the elastic force of the elastic element, thereby increasing the movement resistance of the cable connector in the connection port and preventing the cable from loosening after being inserted. 5. When the limiting block moves downward, it drives the second toothed plate to mesh with the driven gear, causing the driven gear to drive the second rotating shaft to rotate. The first limiting plate on the second rotating shaft limits the rear side of the cable connector, and the second limiting plate limits the side of the cable connector, so that the cable connector is stably inserted into the connection port, ensuring the stability of the cable insertion and further ensuring the use effect of the wiring rack.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0020] Example 1: Refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 9, an infrared induction intelligent monitoring device for a patch panel, including a patch panel body 1, and further including: Connection ports 2, multiple connection ports 2 are provided and arranged equidistantly on the patch panel body 1, and induction lights 101 are arranged on the upper side of the patch panel body 1 at each connection port 2; An infrared monitoring module 3, the infrared monitoring module 3 is arranged in the connection port 2 and is used to monitor the plugging situation of the cable at the connection port 2. The infrared monitoring module 3 includes an infrared emission module and an infrared reception module; Baffles 4, multiple baffles 4 are provided and correspond to the connection ports 2 one by one, and are used to block the connection ports 2. A limiting block 5 for restricting the displacement of the baffle 4 is elastically arranged in the connection port 2; and A storage component, the storage component is arranged on the lower side of the patch panel body 1 and is used to fold and store the baffle 4; Wherein, a dust removal component for dust removal is arranged on the patch panel body 1, and the dust removal component is connected to the storage component.

[0021] Specifically, the infrared monitoring module 3 monitors the plugging situation of the cable at the connection port 2. The infrared emission module sends out infrared rays. If blocked, the infrared rays are reflected and received by the infrared reception module, indicating that a cable connector is plugged into the connection port 2. If the reflected infrared rays are not received, it means that no cable connector is plugged into the connection port 2. The setting of the baffle 4 prevents dust from entering when the connection port 2 is not in use, resulting in the infrared monitoring module 3 being covered with dust, ensuring the accuracy of the infrared monitoring result. When the cable is plugged into the connection port 2, the baffle 4 is folded and laid flat by the storage component, avoiding the baffle 4 occupying too much area on the left and right sides or up and down sides, thereby reducing the space occupied area of the patch panel; when the cable is plugged into the connection port 2 or pulled out from the connection port 2, the action of the storage component can drive the dust removal component to move, so that the dust removal component can discharge air from the inside of the connection port 2 to the outside when the baffle 4 is stored or reset, preventing dust from drifting into the connection port 2 and ensuring the plugging use effect of the connection port 2.

[0022] Example 2: Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 10 , an infrared induction intelligent monitoring device for a patch panel.

A first torsion spring for driving the main board body 403 to rotate back to its original position is arranged between the first rotating shaft 402 and the sliding block 401.

[0023] Furthermore, the storage assembly includes a storage shell 6 fixedly mounted on the lower side of the distribution frame body 1 , the sliding block 401 is slidably connected in the storage shell 6 , and a first elastic element 601 is arranged between the inner wall of the storage shell 6 and the sliding block 401 .

[0024] Furthermore, a movable groove 7 for sliding of the limit block 5 is provided on the inner wall of the connection port 2, a sliding groove 701 is provided on the inner wall of the movable groove 7, a sliding block 702 connected to the limit block 5 is slidably connected to the inner wall of the sliding groove 701, a second elastic element 703 is arranged between the inner wall of the sliding groove 701 and the sliding block 702, a limiting groove 4032 for plugging in the limiting block 5 is provided on the main board body 403, and an extrusion slope is provided on the top of the limiting block 5.

[0025] Specifically, when the cable connector needs to be plugged into the connection port 2, the main board body 403 is manually moved to flip the main board body 403 relative to the sliding block 401, so that the main board body 403 changes from being vertically attached to one side of the connection port 2 to being placed horizontally, and then the main board body 403 is pushed to shrink the main board body 403 into the storage shell 6. When the cable connector is plugged into the connection port 2, the cable connector applies a thrust to the extrusion slope of the limit block 5, so that the limit block 5 moves downward and is plugged into the limit groove 4032 of the baffle 4, and the baffle 4 is limited so that the baffle 4 is folded and stored flat in the storage shell 6, so as to avoid the baffle 4 occupying too much area on the left and right sides or the upper and lower sides, thereby reducing the space occupied by the wiring rack, and the limit block 5 always exerts an upward thrust on the cable connector under the elastic force of the second elastic element 703, thereby increasing the movement resistance of the cable connector in the connection port 2, and avoiding the loosening of the cable after plugging. The first elastic element 601 and the second elastic element 703 can be springs.

[0026] Example 3: Reference Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 , an infrared sensing intelligent monitoring device for a wiring frame, based on Example 2, further, the dust exhaust component includes a dust exhaust shell 8 fixedly mounted on the wiring frame body 1, a piston plate 801 slidably connected to the dust exhaust shell 8, a third elastic element 802 arranged between the piston plate 801 and the inner wall of the dust exhaust shell 8, a sliding rod 803 fixedly connected to the piston plate 801, and a movable plate 804 connected to one end of the sliding rod 803 away from the piston plate 801.

[0027] Furthermore, the piston plate 801 divides the internal cavity of the dust exhaust shell 8 into an upper cavity and a lower cavity, both of which are provided with an air inlet valve 805 and an air outlet valve 806, and an exhaust channel 9 for connecting the air outlet valve 806 and the inner cavity of the connection port 2 is opened in the wiring frame body 1.

[0028] Furthermore, the dust exhaust assembly also includes a rotating rod 10 rotatably connected to the wiring frame body 1, a movable gear 1001 and a reel 1002 arranged on the rotating rod 10, and a pull rope 1003 wound around the reel 1002, the end of the pull rope 1003 away from the reel 1002 passes through the wiring frame body 1 and is connected to the movable plate 804, and a first tooth plate 4031 meshing with the movable gear 1001 is arranged on the main board 403.

[0029] Specifically, when the baffle 4 is retracted into the storage shell 6, the movable gear 1001 on the main body 403 is meshed with the first tooth plate 4031 for transmission, and the movable gear 1001 drives the rotating rod 10 to rotate, and the reel 1002 on the rotating rod 10 reels the pull rope 1003, and the pull rope 1003 pulls the movable plate 804 downward, and the movable plate 804 drives the piston plate 801 to move downward through the sliding rod 803, so that the piston plate 801 squeezes the air in the lower cavity, and the air in the lower cavity is discharged to the inside of the connection port 2 through the outlet valve 806 and the exhaust channel 9; when the baffle 4 is reset and moved back, the main body 403 The movable gear 1001 on the upper part meshes with the first tooth plate 4031 in the reverse direction, the reel 1002 on the rotating rod 10 releases the pull rope 1003, the movable plate 804 is no longer subjected to force, and the piston plate 801 moves back under the elastic force of the third elastic element 802. The piston plate 801 squeezes the air in the upper cavity, and the air in the upper cavity is discharged to the inside of the connection port 2 through the exhaust channel 9 when the baffle 4 moves back, so that the dust exhaust component can discharge air from the inside of the connection port 2 to the outside when the baffle 4 is stored or reset, thereby preventing dust from drifting into the inside of the connection port 2 and ensuring the plug-in use effect of the connection port 2.

[0030] Example 4: Reference Figure 4 , Figure 5 , Figure 9 , Figure 10 , Figure 11 and Figure 11 , an infrared sensing intelligent monitoring device for a distribution frame, based on Example 3, further, a second rotating shaft 11 is rotatably connected in the distribution frame body 1, a driven gear 111 is provided on the second rotating shaft 11, a second tooth plate 501 meshing with the driven gear 111 is provided on the limit block 5, and one end of the second rotating shaft 11 away from the driven gear 111 passes through the distribution frame body 1 and is connected to the first limiting plate 112, and a second torsion spring is provided between the first limiting plate 112 and the second rotating shaft 11.

[0031] Furthermore, a second limiting plate 113 is disposed on the second rotating shaft 11 , and a third torsion spring is disposed between the second limiting plate 113 and the second rotating shaft 11 .

[0032] Further, a rubber pad 12 is fixedly arranged on the first limiting plate 112. An air cavity 121 is formed in the rubber pad 12. An air guide pipe 1211 is connected to the air cavity 121. A pneumatic elastic telescopic rod 13 communicated with the air guide pipe 1211 is fixedly arranged in the second rotating shaft 11. A plurality of positioning holes 131 matched with the pneumatic elastic telescopic rod 13 are uniformly formed in the inner side wall of the second limiting plate 113 in a circumferential manner.

[0033] Specifically, after the cable connector is inserted into the connection port 2, the cable connector applies a thrust to the extrusion inclined surface of the limiting block 5. When the limiting block 5 moves downward under the force, the second toothed plate 501 meshes with the driven gear 111 on the second rotating shaft 11 for transmission. The driven gear 111 drives the second rotating shaft 11 to rotate. The second rotating shaft 11 drives the first limiting plate 112 and the second limiting plate 113 to rotate. When the cable connector has not abutted against the inner wall of the connection port 2, the first limiting plate 112 and the second limiting plate 113 abut against the cable connector when rotating with the second rotating shaft 11. The second rotating shaft 11 still continues to rotate. After the cable connector abuts against the inner wall of the connection port 2, the first limiting plate 112 no longer abuts against the cable connector. The first limiting plate 112 abuts against one end of the cable connector far away from the inner wall of the connection port 2. The rubber pad 12 on the first limiting plate 112 touches the cable connector. The air cavity 121 of the rubber pad 12 is squeezed. The air in the air cavity 121 is introduced into the pneumatic elastic telescopic rod 13 through the air guide pipe 1211. The pneumatic elastic telescopic rod 13 stretches and is inserted into the positioning hole 131 on the second limiting plate 113, so as to lock the position of the second limiting plate 113, limit the rear side of the cable connector by the first limiting plate 112, and prevent the cable connector from moving backward in the connection port 2. The second limiting plate 113 limits the side of the cable connector to prevent the cable connector from shaking left and right, so that the cable connector is stably inserted into the connection port 2, ensuring the stability of the cable insertion and further ensuring the use effect of the wiring rack.
