Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment, and more specifically, to a waterproof top cover of an integrated distribution box. Background Art

[0002] Integrated distribution boxes are widely used in existing communication networks. Integrated distribution boxes rely on top covers to protect the equipment inside the box from external environmental influences such as rain, dust, and direct sunlight. Therefore, the design of the top cover must comprehensively consider multiple factors such as waterproofing, heat dissipation, strength, stability, corrosion resistance, opening and fixing mechanism, safety, and aesthetics.

[0003] The existing integrated distribution box top covers on the market have the following disadvantages. First, many existing top covers adopt a flat top structure. Although it is easy to install and use, it is easy to accumulate water. Second, the top cover must be fixed with glue to prevent rainwater from seeping in or accumulating, but this will restrict the opening of the top cover. In addition, there are structural defects in the ventilation holes, and the waterproof performance is poor. Figures 1 and 2 As shown, the existing ventilation hole 210 on the front of the existing top cover 200 is flush with the upper edge of the main box body 100. If there is splashing water, it is easy for water to enter the upper part of the main box body 100. Even if the ventilation hole is changed to a sunken structure, it is easy for water to enter the inside of the chassis due to splashing water. Utility Model Content

[0004] The utility model aims to overcome at least one of the deficiencies of the above-mentioned prior art and provides a waterproof top cover for an integrated wiring box, which improves the waterproof performance of the integrated wiring box while ensuring ventilation and heat dissipation.

[0005] The technical solution adopted by the present invention is to provide a waterproof top cover of an integrated distribution box, including a top cover body and a top cover mounting plate, which are used to cover and connect the main box body of the integrated distribution box. The top cover mounting plate is fixedly connected to the inner side of the rear end of the top cover body, and a waterproof structure is provided at the bottom of the front end of the top cover body. The waterproof structure is provided with ventilation holes opening toward the inner side of the top cover body, and the waterproof structure divides the front side wall of the top cover body into an upper section and a lower section.

[0006] In the above scheme, the fixed connection part composed of the top cover body and the top cover mounting plate has an overall inner cavity larger than the main box body, covering the entire main box body and effectively preventing rainwater from entering the main box body. The top cover mounting plate is fixedly connected to the inner side of the rear end of the top cover body, so that after installation, the waterproof top cover is completely covered outside the main box body, which can effectively prevent rainwater from entering the main box body; in addition, it also saves sealing material, avoiding the inconvenience of opening the cover for maintenance of the integrated wiring box. The front side wall of the top cover body is divided into an upper section and a lower section, with the upper section of the front side wall on the outside and the lower section of the front side wall on the inside. The waterproof structure containing ventilation holes is provided at the bottom front end of the top cover body, so that rainwater does not fall near the ventilation holes; the ventilation holes are provided to meet the ventilation and heat dissipation needs of the equipment in the integrated wiring box; the ventilation holes are opened towards the inside of the top cover body, making it difficult for splashing water to enter the ventilation holes. This waterproof structure design prevents splashing water from entering the top of the main box body through the top cover ventilation holes, effectively improving the waterproof performance of the integrated wiring box.

[0007] Furthermore, the waterproof structure has an inverted S-shaped cross-section and includes a drainage trough, a ventilation grille, and an arched bridge, connected sequentially from front to back. The drainage trough connects to the upper section of the front side wall of the roof body, the arched bridge connects to the lower section of the front side wall of the roof body, the ventilation grille is vertical or inclined, and the ventilation holes are provided at the lower end of the ventilation grille. The ventilation holes are square or arched. The inverted S-shaped waterproof structure uses the ventilation holes as drainage holes, located at the lower end of the ventilation grille. The lower end of the ventilation grille is connected to the drainage trough. Therefore, even if splashing water enters the front end of the roof through the ventilation holes, it can be drained away in a timely manner, preventing long-term water accumulation from causing roof corrosion.

[0008] Furthermore, the connection between the drainage groove and the ventilation grille is chamfered, which is conducive to draining the accumulated water and preventing the top cover from being rusted due to long-term water accumulation at the connection.

[0009] Furthermore, the ventilation hole is square or arched, the width of the ventilation hole does not exceed 3 cm, and the height is 2 to 10 cm.

[0010] Furthermore, the lower end of the vent hole is lower than or flush with the lower edge of the upper section of the front side wall of the top cover body. The lower end of the vent hole is lower than or flush with the bottom of the waterproof structure, forming an inclined surface to facilitate the drainage of rainwater or condensation water through the drainage trough, so that water does not accumulate in the top cover.

[0011] Furthermore, a top cover fixing hole is provided on the lower section of the front side wall of the top cover body for fixedly connecting to the main box body.

[0012] Furthermore, the top cover mounting plate is provided with mounting holes for fixedly connecting to the main box body.

[0013] Furthermore, the top cover fixing holes correspond to the mounting holes one-to-one, and the line connecting the top cover fixing holes and the corresponding mounting holes is parallel to the side of the top cover body. Since the top cover body is installed and is inserted into the outside of the main box, this design facilitates the alignment and close contact of the side of the top cover body with the main box.

[0014] Furthermore, the upper edge of the lower section of the front side wall of the top cover body is flush with or lower than the top cover mounting plate, so as to facilitate the installation of the top cover body on the main box body.

[0015] Furthermore, the upper portion of the top cover body is an inclined structure, which can prevent water from accumulating on the top cover and allow condensed water in the top cover to flow down the side along the inclined inner wall and be discharged from the drainage groove and ventilation holes.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This utility model provides a waterproof top cover for an integrated wiring box. This structure prevents water from accumulating on top of the cover through an inclined structure. The waterproof structure is located at the front bottom of the cover body and has ventilation holes facing the inside of the cover body, preventing rainwater and splashing water from entering. The waterproof structure has an inverted S-shaped cross section, and the ventilation holes also serve as drainage holes, allowing water accumulated at the front end of the cover to be promptly drained, preventing rust on the cover caused by long-term water accumulation. This waterproof top cover not only ensures ventilation and heat dissipation for the equipment within the integrated wiring box, but also provides excellent waterproof performance, making it worthy of widespread promotion.

DETAILED DESCRIPTION

[0026] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0027] like Figures 3 to 6 As shown, this embodiment provides a waterproof top cover of an integrated distribution box, including a top cover body 300 and a top cover mounting plate 400, which are used to cover and connect the main box body 100 of the integrated distribution box. The top cover mounting plate 400 is fixedly connected to the inner side of the rear end of the top cover body 300, and a waterproof structure is provided at the bottom front end of the top cover body 300. The waterproof structure is provided with a ventilation hole 331 with an opening toward the inner side of the top cover body 300. The waterproof structure divides the front side wall of the top cover body 300 into an upper section and a lower section.

[0028] In the above solution, the fixed connection member composed of the top cover body 300 and the top cover mounting plate 400 has an overall inner cavity larger than the main box body 100, covering the entire main box body 100, which can effectively prevent rainwater from entering the main box body 100. After the installation is completed, the top cover mounting plate 400 is fixedly connected to the inner side of the rear end of the top cover body 300. Figure 7 As shown, the waterproof top cover is integrally covered on the outside of the main box 100, which can effectively prevent rainwater from entering the main box 100; in addition, the sealing material is omitted, avoiding the inconvenience of opening the cover for maintenance of the integrated distribution box.

[0029] As shown in the figure, the front side wall of the top cover body 300 is divided into an upper section and a lower section, with the upper section 310 of the front side wall on the outside and the lower section 350 of the front side wall on the inside. A waterproof structure including ventilation holes 331 is provided at the front bottom of the top cover body 300 to prevent rainwater from falling near the ventilation holes 331. The ventilation holes 331 are provided to meet the ventilation and heat dissipation requirements of the equipment in the integrated wiring box. The ventilation holes 331 open toward the inside of the top cover body 300, making it difficult for splashing water to enter the ventilation holes 331. This waterproof structural design prevents splashing water from entering the top of the main box 100 through the top cover ventilation holes 331, effectively improving the waterproof performance of the integrated wiring box.

[0030] like Figures 4 and 5As shown, the cross-section of the waterproof structure is an inverted S-shape; the waterproof structure includes a drainage trough 320, a ventilation grille 330, and an arched bridge 340, which are connected in sequence from front to back. The drainage trough 320 connects to the upper section 310 of the front side wall of the top cover body 300, and the arched bridge 340 connects to the lower section 350 of the front side wall of the top cover body 300. The ventilation grille 330 is vertical or inclined, and the ventilation hole 331 is provided at the lower end of the ventilation grille 330. The ventilation hole 331 is square or arched. The inverted S-shaped waterproof structure uses the ventilation hole 331 as a drainage hole. The ventilation hole 331 is provided at the lower end of the ventilation grille 330, and the lower end of the ventilation grille 330 is connected to the drainage trough 320. Therefore, even if splashing water enters the front end of the top cover through the ventilation hole 331, it can be drained away in time, preventing long-term water accumulation from causing corrosion of the top cover.

[0031] like Figures 4 and 5 As shown, the connection between the drainage groove 320 and the ventilation grille 330 is chamfered, which is conducive to draining the accumulated water and preventing the top cover from rusting due to long-term accumulation of water at the connection.

[0032] The ventilation hole 331 is square or arched, and has a width of 3 cm and a height of 8 cm.

[0033] The lower section 350 of the front side wall of the top cover body 300 is provided with a top cover fixing hole 351 for fixing the top cover to the main box body 100 .

[0034] The top cover mounting plate 400 is provided with mounting holes 410 for fixedly connecting to the main box body 100 .

[0035] The top cover fixing holes 351 correspond to the mounting holes 410 one-to-one, and the line connecting the top cover fixing holes 351 and the corresponding mounting holes 410 is parallel to the side of the top cover body 300. Since the top cover body 300 is inserted into the outside of the main case 100 after installation, this design facilitates the alignment and close contact of the side of the top cover body 300 with the main case 100.

[0036] The upper edge of the front side wall lower section 350 of the top cover body 300 is flush with or lower than the top cover mounting plate 400 , so as to facilitate the installation of the top cover body 300 on the main box body 100 .

[0037] The upper portion of the top cover body 300 is an inclined structure. On the one hand, it can prevent water from accumulating on the upper portion of the top cover; on the other hand, it allows condensed water in the top cover to flow down the side along the inclined inner wall and be discharged from the drainage groove 320 and the ventilation hole 331.

[0038] This embodiment provides a waterproof top cover for an integrated wiring box. This structure prevents water from accumulating on top of the cover through an inclined structure. The waterproof structure is located at the front bottom of the cover body 300 and is provided with ventilation holes 331, which open toward the inside of the cover body 300, preventing rainwater and splashing water from entering. The waterproof structure has an inverted S-shaped cross-section, and the ventilation holes 331 also serve as drainage holes, allowing water accumulated at the front end of the cover to be promptly drained, preventing corrosion of the cover caused by long-term water accumulation. This embodiment's waterproof top cover not only ensures ventilation and heat dissipation for the equipment within the integrated wiring box, but also provides excellent waterproof performance, making it worthy of widespread promotion.
