Description

Technical Field

[0001] The utility model belongs to the technical field of junction boxes, and in particular relates to a pressure-resistant and moisture-proof junction box for broadcasting and television engineering. Background Art

[0002] With the development of science and technology and society, various electrical equipment has been widely used. In the process of radio and television projects entering households, junction boxes on the wall can be seen everywhere. Most of them are made of metal and contain various wires. Junction boxes can facilitate the connection of cables and play an increasingly important role. In the radio and television transmitter room, due to the large number of lines, junction boxes are needed to store the lines.

[0003] However, during storage, due to the large number of lines and heavy load in the junction box, a large amount of heat is easily generated in the box. Therefore, the junction box is usually placed in a ventilated and cool place. Although this method can speed up heat dissipation, it is also easy to bring a large amount of moisture into the junction box, which can easily cause the cables to get damp and affect their use. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a pressure-resistant and moisture-proof junction box for radio and television engineering, and the technical solution adopted is:

[0005] A compression-resistant and moisture-proof cable junction box for broadcasting and television engineering, comprising a box body, a cover plate installed on the top of the box body, a plurality of hanging plates arranged inside the box body, a card table for supporting the hanging plates to slide arranged on both sides of the box body, a plurality of openings for cables to pass through are respectively opened on both sides of the box body and below each layer of hanging plates, and rubber sleeves are arranged in the openings;

[0006] A card slot for embedding a card block is provided on the lower surface of the hanging plate, a rectangular opening is provided in the box body and on one side of the card platform, a side frame is installed at a position corresponding to the rectangular opening outside the box body, a ventilation hole is provided on the surface of the side frame, and a filter plate is inserted into the inside of the side frame.

[0007] Furthermore, the width of the hanging plate is less than half of the width of the box body, and the length of the card platform is less than the width of the hanging plate, so when the hanging plate slides away from the card platform, it can be removed.

[0008] Furthermore, the opening positions in the box body where no cables are passed through are all provided with plugs in contact with the rubber sleeve.

[0009] Furthermore, the clamping block adopts a U-shaped structure with an opening at the top. Both sides of the opening are provided with convex plates extending outward, and the convex plates are embedded in the clamping slot to realize the lifting of the clamping block.

[0010] Furthermore, an opening for inserting the filter plate is provided on one side of the side frame. After the filter plate is inserted, the filter plate is located between the ventilation holes of the side frame and the rectangular opening of the box body. The filter plate is an activated carbon filter plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] When the utility model is in use, the outside air can circulate through the ventilation holes in the two side frames, avoiding the overheating of the cables in the box body, reducing potential safety hazards. At the same time, after the filter plate is inserted into the side frame, it is placed between the ventilation holes of the side frame and the rectangular opening of the box body, and the filter plate is an activated carbon filter plate. When the air passes through the side frame and enters the box body, it can isolate the dust and moisture in the air, thereby reducing the moisture in the box body and avoiding the safety hazards caused by dampness in the box body.

[0013] The utility model is provided with rubber sleeves in the openings on both sides of the box body. After the cables pass through, the rubber sleeves can tightly wrap the cables to avoid abrasion of the cables at the openings; when there is no cable passing through the corresponding rubber sleeve, a plug will be used to block it to prevent humid air from entering from here, which can reduce the influence of humid air on the cables in the box body.

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0024] As attached Figure 1-7 shown.

[0025] A pressure-resistant and moisture-proof junction box for broadcasting and television engineering includes a box body 1, a cover plate 11 is installed on the top of the box body 1, a multi-layer hanging plate 2 is arranged inside the box body 1, and a card table 12 for supporting the sliding of the hanging plate 2 is arranged on both sides of the box body 1. The width of the hanging plate 2 is less than half of the width of the box body 1. The hanging plate 2 is installed in a sliding manner. After the hanging plate 2 slides out of the position of the card table 12, the hanging plate 2 can be removed.

[0026] A plurality of openings for passing cables are provided on both sides of the box body 1 and below the lower surface of the hanging plate 2. Rubber sleeves 13 are provided in the openings. After the cables pass through, the rubber sleeves 13 can tightly wrap the cables to prevent humid air from entering from here and also prevent the cables from being worn at the openings. When no cable passes through the corresponding rubber sleeves 13, a plug 14 will be used to seal it.

[0027] A card slot 21 is provided on the lower surface of the hanging plate 2 at the position corresponding to the opening through which the cable passes. A card block 3 for supporting the cable is installed in the card slot 21 through a sliding connection. The card block 3 adopts a U-shaped structure with an opening on the top. Both sides of the opening are provided with convex plates extending outward. The convex plates are embedded in the card slot 21 to realize the hanging of the card block 3.

[0028] As attached Figure 7 As shown, due to the structural setting of the card block 3, the card block 3 is installed as follows: after the cables pass through the corresponding openings on both sides of the box body 1, the card block is placed under the corresponding cable, the cable is placed inside the card block, and then the card block 3 can be inserted into the card slot 21 at the corresponding position from one side of the hanging plate 2 to achieve the installation of the card block 3.

[0029] At the same time, when removing the hanging plate 2, it is necessary to first remove the block 3 from the bottom of the hanging plate 2, and then slide the hanging plate 2 to the side where the card platform 12 is not installed, so that the hanging plate 2 can be removed.

[0030] On both sides of the clamping platform 12 in the box body 1 and on one side of the clamping platform 12, rectangular openings are provided. On the outside of the box body 1, side frames 4 are respectively installed at positions corresponding to the rectangular openings. The side frames 4 are slightly larger than the rectangular openings. Vent holes are provided on the surface of the side frames 4. An opening for inserting a filter plate 5 is provided on one side of the side frames 4. After the filter plate 5 is inserted into the side frames 4, it is placed between the vent holes of the side frames 4 and the rectangular openings of the box body 1, and can filter the gas entering the box body 1 from the vent holes of the side frames 4.

[0031] After being used for a period of time, the filter plate 5 can be taken out for replacement.

[0032] The use process of this device is as follows: When using this device for cable collection, it is necessary to first thread the cables through the openings at the bottommost part. After the bottommost opening is filled, the lifting plate 2 is installed in the bottommost clamping platform 12, and then the cable ends are successively hoisted and fixed under the lifting plate 2 by using the clamping blocks 3 to prevent the cables from getting entangled.

[0033] After the installation structure of the lifting plate 2 and the clamping blocks 3 at this position, the cables are then threaded through the openings of the box body 1 above the lifting plate 2 at this time. Then, after completion, the lifting plate 2 and the clamping blocks 3 are installed in sequence. This installation method can ensure that the cables in the box body 1 are neatly arranged, and it is very convenient to add cables later. It only needs to be threaded next to the previous cable.

[0034] When this device is in use, the outside air can circulate through the vent holes in the two side frames 4, preventing the temperature of the cables in the box body 1 from being too high and reducing potential safety hazards. At the same time, the filter plate 5 uses an activated carbon filter plate, which can isolate dust and moisture in the air when the air passes through the side frames 4 and enters the box body 1, thereby reducing the moisture in the box body 1 and avoiding potential safety hazards caused by moisture in the box body 1.

[0035] To further improve the heat dissipation of the cables, the clamping blocks 3 used in the device adopt a design with multiple hollow openings, which can reduce the contact area with the cables while fixing and hoisting the cables, and reduce the working pressure of the cables.

[0036] And during the use process, the lifting plate 2 arranged in the box body 1 serves as a reinforcing rib, which can play a role in supporting the box body and protecting the cables, thus having a certain compressive performance. When the box body 1 is subjected to impact or collision, it can ensure the integrity of the box body 1, and is not easily deformed or extrude the cables.

[0037] Any technical solution using the technical solution of the present invention, or any technical solution designed by those skilled in the art inspired by the technical solution of the present invention and achieving the above technical effects falls within the protection scope of the present invention.
