[0003] In actual use, the connection port on the wireless transmitting device will be connected to a longer network cable. The network cable is generally laid on the wall or on the ground indoors. Half of the network cable will have extra length so that when the network cable connector is damaged, a new connector can be reinstalled at the end of the network cable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When laying the network cable, the excess length of the network cable can be wrapped around the sleeve to avoid arranging too long network cables indoors, thereby reducing the probability of people moving around accidentally pulling the network cable. When the network cable is pulled away from the box by external force, the slide plate will slide away from the box to buffer the external pulling force. The sleeve will rotate under the action of the external pulling force to buffer the external pulling force, thereby preventing the network cable inside the box from being pulled, and then preventing the network cable connector inside the box from being pulled, so as to prevent the network cable connector connected to the port body from loosening and the connection between the network cable connector and the connection port body from being disconnected, which is beneficial to the use of the wireless transmitting component; after the external pulling force disappears, the elastic force of the spring will pull the slide plate back, so that the slide plate returns to its original position. In addition, the elastic force of the torsion spring will cause the sleeve to rotate, so as to rewind the pulled network cable;

[0019] 2. When the temperature inside the box is too high, the electric telescopic rod will drive the moving plate to cyclically extend or shorten. When the electric telescopic rod is extended, the moving plate moves away from the box, thereby increasing the ventilation area, allowing more cold air to enter the box through the rectangular opening on the box, thereby enhancing the heat dissipation effect inside the box. At the same time, the airbag continuously absorbs the heat inside the box and continuously discharges the absorbed heat to the outside, thereby increasing the heat dissipation effect on the box;

[0020] 3. If the box falls accidentally, the side where the moving board is located will fall to the ground first. When the horizontal board falls to the ground, the airbag will cushion the impact, thereby cushioning the box and protecting the wireless transmitting components inside the box.

[0021] 4. When the moving plate moves away from or towards the box, the flexible bristles on the cleaning brush plate will repeatedly sweep the dustproof net to remove the dust on the dustproof net, making the ventilation performance of the dustproof net good, which is conducive to the external air passing through the dustproof net into the box, and is conducive to ventilation and heat dissipation inside the box.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-Figure 7 As shown, the present invention provides a connection port for wireless transmitting equipment inside a building, including a port body 11 for connecting a network cable, the port body 11 is arranged on the shell of a wireless transmitting component 10, the wireless transmitting component 10 is located inside a box body 1, the top of the box body 1 is connected to an upper cover plate 2, one side of the box body 1 has a rectangular opening, the port body 11 is located at the rectangular opening, the inside of the rectangular opening is slidably connected to a moving plate 7, the moving plate 7 is provided with a threading hole 26 corresponding to the port body 11, the threading hole 26 is provided with a dustproof mechanism, and the moving plate A horizontal plate 8 is connected to the bottom of the box body 1, and a cable harness mechanism for winding the network cable is provided at the top of the horizontal plate 8. An electric telescopic rod 12 for driving the movable plate 7 away from or close to the box body 1 is provided at the bottom of the upper cover plate 2. The electric telescopic rod 12 is connected to the movable plate 7 through a connecting mechanism. A heat dissipation mechanism is also provided at the bottom of the upper cover plate 2. A ventilation hole is provided on the vertical side wall of the box body 1 close to the movable plate 7. A dustproof net 6 for covering the outer opening of the ventilation hole is connected to the outer wall of the box body 1. Cleaning mechanisms for cleaning the dustproof net 6 are connected to both ends of the movable plate 7.

[0033] It should be noted that an exhaust fan (not shown) for extracting hot air from the inside of the box 1 is installed on the side wall of the box 1 away from its rectangular opening. The exhaust fan is used to extract the hot air from the inside of the box 1, while the cold air from the outside flows into the inside of the box 1 from the ventilation holes, thereby dissipating the heat inside the box 1; a temperature sensor (not shown) for monitoring the internal temperature of the box 1 and a controller (not shown) for controlling the operation of the electric telescopic rod 12 are also installed inside the box 1. When the temperature inside the box 1 is too high, the temperature sensor transmits the detected temperature signal to the controller. After processing the received temperature signal, the controller controls the electric telescopic rod 12 to cyclically perform an extension-contraction action. When the electric telescopic rod 12 pushes the movable plate 7 away from or close to the box 1, the ventilation area is increased, so that more cold air can enter the inside of the box 1 through the rectangular opening on the box 1, thereby enhancing the heat dissipation effect inside the box 1.

[0034] like Figure 1 and Figure 6 As shown, the dustproof mechanism includes an annular plate 27 fixedly connected to the inner circumference of the threading hole 26, and the inner side of the annular plate 27 has a circular hole for threading the network cable. The annular plate 27 is used to prevent dust and other debris from entering the box body 1.

[0035] like Figure 1 and Figure 6As shown, the annular plate 27 is composed of a plurality of fan-shaped plates arranged in an annular array, and the plurality of fan-shaped plates are made of soft rubber. The fan-shaped plates made of soft rubber can be bent, so that the network cable and the connector at the end of the network cable can be inserted into the threading hole 26 conveniently.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the cable bundling mechanism includes vertical plates 9 arranged in parallel, a connecting rod 21 is provided between the two vertical plates 9, the outside of the connecting rod 21 is provided with a sleeve 22 for winding the network cable, and the connecting rod 21 is provided with a torsion spring 25 on both sides of the sleeve 22, one end of the torsion spring 25 is fixedly connected to the circumference of the connecting rod 21, and the other end of the torsion spring 25 is fixedly connected to the vertical surface of the sleeve 22, and limiting rings 24 for preventing the network cable from escaping from the sleeve 22 are fixedly fixed on both sides of the outer circumference of the sleeve 22, and the two ends of the connecting rod 21 are connected to the two vertical plates 9 through buffer devices. When laying the network cable, the excess length of the network cable can be wrapped around the sleeve 22 to avoid the network cable of too long being arranged indoors, thereby reducing the probability of people moving around accidentally being involved in the network cable; when the network cable arranged indoors and located outside the box 1 is pulled away from the box 1 by an external force, the pulling force will act on the sleeve 22, and the sleeve 22 will rotate under the action of the external pulling force to buffer the external pulling force, thereby preventing the network cable located inside the box 1 from being pulled, and then preventing the network cable connector inside the box 1 from being pulled, thereby preventing the network cable connector connected to the port body 11 from loosening; when the network cable is pulled, the torsion spring 25 will limit the rotation angle of the sleeve 22 to prevent the sleeve 22 from rotating too much, and when the network cable is loosened, the elastic force of the torsion spring 25 will cause the sleeve 22 to rotate, thereby rewinding the pulled network cable.

[0037] like Figure 1 and Figure 4As shown, the buffer device includes a slide plate 20 fixedly connected to the end of the connecting rod 21, and a slide groove 19 is provided on the side wall of the vertical plate 9 facing the connecting rod 21. The slide plate 20 is slidably connected in the slide groove 19, and the side of the slide plate 20 facing the movable plate 7 is connected to the vertical side wall of the slide groove 19 close to the movable plate 7 through a spring 23. When the network cable arranged indoors and located outside the box body 1 is pulled away from the box body 1 by an external force, the slide plate 20 will slide away from the box body 1, thereby buffering the external pulling force, thereby preventing the network cable located inside the box body 1 from being pulled, and further preventing the network cable connector inside the box body 1 from being pulled, thereby preventing the network cable connector connected to the port body 11 from loosening; when the slide plate 20 slides away from the box body 1, the spring 23 is stretched, and when the network cable is loosened, the elastic force of the spring 23 will pull the slide plate 20 back, so that the sleeve 22 returns to its original position. When laying the network cable, a certain length of the network cable needs to be reserved inside the box 1. When the slide plate 20 slides in a direction away from the box 1, the network cable connector inside the box 1 will not be involved.

[0038] like Figure 1 , Figure 2 and Figure 7 As shown, the connection mechanism includes a limit plate 28 fixedly connected to one side of the movable plate 7 toward the box body 1, and a card slot is provided on the side of the limit plate 28 toward the electric telescopic rod 12, and a push plate 29 for being carded in the card slot is fixedly connected to the extended end of the electric telescopic rod 12. The length of the card slot along the extension direction of the electric telescopic rod 12 is greater than the thickness of the push plate 29 along the extension direction of the electric telescopic rod 12. When the push plate 29 pushes the card slot to approach the vertical side of the box body 1, the limit plate 28 will move toward the box body 1, and the movable plate 7 moves toward the box body 1 along with the limit plate 28. When the push plate 29 pushes the card slot to approach the vertical side of the movable plate 7, the limit plate 28 will move away from the box body 1, and the movable plate 7 will move away from the box body 1 along with the limit plate 28.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, the heat dissipation mechanism includes a first fixed plate 13 connected to the vertical side surface of the movable plate 7 toward the box body 1, a second fixed plate 15 fixedly connected to the bottom end of the upper cover plate 2, and an air bag 14 used to fix the first fixed plate 13 and the second fixed plate 15. The top of the air bag 14 is connected with an exhaust pipe 16, the top of the exhaust pipe 16 extends to the outside through the upper cover plate 2 and is connected with a first one-way valve 3. The first one-way valve 3 allows the air inside the air bag 14 to be discharged to the outside through the exhaust pipe 16, while the external air cannot enter the air bag 14 through the exhaust pipe 16. The bottom end of the air bag 14 is connected with an intake pipe 17, and the bottom of the intake pipe 17 is connected with a second one-way valve 18. The second one-way valve 18 allows the hot air inside the box body 1 to enter the air bag 14 through the intake pipe 17, while the air inside the air bag 14 cannot enter the box body 1 through the intake pipe 17. When the movable plate 7 is away from the box body 1, the first fixed plate 13 moves with the movable plate 7, thereby pulling the airbag 14 to make the airbag 14 stretch out, and then the airbag 14 inhales air, so that the hot air inside the box body 1 enters the airbag 14 through the intake pipe 17; when the movable plate 7 is close to the box body 1, the first fixed plate 13 moves with the movable plate 7, thereby squeezing the airbag 14 to make the airbag 14 contract, and then the airbag 14 discharges the hot air inside itself, and the hot air inside the airbag 14 is discharged to the outside through the exhaust pipe 16, thereby increasing the heat dissipation effect.

[0040] like Figure 1 and Figure 2 As shown, the cleaning mechanism includes a cleaning brush plate 4 for sweeping the dustproof net 6, the cleaning brush plate 4 is fixedly connected to the movable plate 7 through a connecting frame 5, and flexible bristles are provided on the side of the cleaning brush plate 4 facing the box body 1; in the process of the movable plate 7 moving away from or approaching the box body 1, the cleaning brush plate 4 will move with the movable plate 7, and in the process of the movement of the cleaning brush plate 4, the flexible bristles will sweep the dustproof net 6 to brush away the dust on the dustproof net 6, so that the ventilation performance of the dustproof net 6 becomes good, which is conducive to the external air passing through the dustproof net 6 into the interior of the box body 1, and is conducive to ventilation and heat dissipation of the interior of the box body 1.

[0041] like Figure 1 As shown, when the movable plate 7 seals the rectangular opening on the box body 1, the cleaning brush plate 4 is located on the side of the dustproof net 6 away from the movable plate 7. The cleaning brush plate 4 will not block the dustproof net 6, avoiding the cleaning brush plate 4 blocking the dustproof net 6 and affecting the ventilation effect of the dustproof net 6.

[0042] Working principle: The ring plate 27 is used to prevent dust and other debris from entering the box body 1. The ring plate 27 is composed of a plurality of fan-shaped plates made of soft rubber. The fan-shaped plates can be bent to facilitate the insertion of the network cable and the connector at the end of the network cable into the threading hole 26;

[0043] When laying the network cable, the excess length of the network cable can be wound around the sleeve 22 to avoid arranging the network cable of excessive length indoors, thereby reducing the probability of people moving around accidentally being involved in the network cable;

[0044] When the network cable arranged indoors and located outside the box body 1 is pulled away from the box body 1 by an external force, the slide plate 20 will slide away from the box body 1, thereby buffering the external pulling force. In addition, the pulling force will also act on the sleeve 22, and the sleeve 22 will rotate under the action of the external pulling force to buffer the external pulling force, thereby preventing the network cable inside the box body 1 from being pulled, and further preventing the network cable connector inside the box body 1 from being pulled, thereby preventing the network cable connector connected to the port body 11 from being loosened, and preventing the network cable connector from being loosened. The connection with the connection port body 11 is disconnected, which is beneficial to the use of the wireless transmitting component 10; when the network cable is pulled, the slide plate 20 will slide away from the box body 1, and the spring 23 will be stretched. In addition, the torsion spring 25 will limit the rotation angle of the sleeve 22 to prevent the sleeve 22 from rotating too much. When the network cable is loosened, the elastic force of the spring 23 will pull the slide plate 20 back, so that the slide plate 20 returns to its original position. In addition, the elastic force of the torsion spring 25 will cause the sleeve 22 to rotate, so as to rewind the pulled network cable;

[0045] When the temperature inside the box 1 is too high, the electric telescopic rod 12 will drive the moving plate 7 to cyclically extend or shorten. When the electric telescopic rod 12 is extended, the moving plate 7 is away from the box 1, thereby increasing the ventilation area, so that more cold air can enter the box 1 through the rectangular opening on the box 1, thereby enhancing the heat dissipation effect inside the box 1. At the same time, when the moving plate 7 is away from the box 1, the first fixed plate 13 moves with the moving plate 7, thereby pulling the airbag 14 to make the airbag 14 extend, thereby making the airbag 14 inhale air, so that the hot air inside the box 1 enters the airbag 14 through the suction pipe 17. When the electric telescopic rod 12 is shortened, the movable plate 7 approaches the box body 1, and the first fixed plate 13 moves with the movable plate 7, thereby squeezing the airbag 14 to make the airbag 14 contract, so that the airbag 14 discharges the hot air inside itself, and the hot air inside the airbag 14 is discharged to the outside through the exhaust pipe 16. The airbag 14 continuously absorbs the hot air inside the box body 1 and continuously discharges the absorbed hot air to the outside, thereby increasing the heat dissipation effect of the box body 1; after the temperature inside the box body 1 drops to a suitable temperature, the electric telescopic rod 12 drives the movable plate 7 to approach the box body 1 until the movable plate 7 seals the rectangular opening on the box body 1;

[0046] When the movable plate 7 seals the rectangular opening on the box body 1, the push plate 29 is close to the vertical side of the box body 1 close to the card slot. If the box body 1 falls accidentally, the cross plate 8 on the movable plate 7 and the wire harness mechanism on the cross plate 8 increase the weight of the side where the movable plate 7 is located, causing the center of gravity of the present invention to shift to the side where the movable plate 7 is located. During the falling process, the side where the movable plate 7 is located will fall to the ground first. When the cross plate 8 falls to the ground, the cross plate 8 will push the movable plate 7 to move closer to the box body 1 due to the impact force in the ground, causing the movable plate 7 to simultaneously apply a thrust to the limit plate 28 and the airbag 14. Since the card slot in the limit plate 28 is close to the vertical side of the movable plate 7 and the push plate 29 on the electric telescopic rod 12, the movable plate 7 will first apply a thrust to the airbag 14, and the airbag 14 will buffer the thrust received, thereby buffering the box body 1, thereby protecting the wireless transmitting component 10 inside the box body 1;

[0047] In addition, when the moving plate 7 moves away from or close to the box body 1, the cleaning brush plate 4 will move with the moving plate 7. During the movement of the cleaning brush plate 4, the flexible bristles will sweep the dustproof net 6 to brush away the dust on the dustproof net 6, so that the ventilation performance of the dustproof net 6 becomes good, which is conducive to the external air passing through the dustproof net 6 into the box body 1, and is conducive to ventilation and heat dissipation of the box body 1.

[0048] When the movable plate 7 seals the rectangular opening on the box body 1, the cleaning brush plate 4 is located on the side of the dustproof net 6 away from the movable plate 7; the cleaning brush plate 4 will not block the dustproof net 6, avoiding the cleaning brush plate 4 blocking the dustproof net 6 and affecting the ventilation effect of the dustproof net 6.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
