Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a reliable and durable waterproof structure for an optoelectronic integrated wiring box. Background Technology

[0002] Currently, most of the waterproof structures on the top covers of existing optoelectronic integrated wiring boxes on the market adopt a flat-top structure. The height of the ventilation holes on the top cover is the same as the height of the main body of the integrated wiring box, with a height difference of only one material thickness. Due to factors such as the tilt of the box during installation, rainwater may enter the box through the ventilation holes.

[0003] The existing structure has the following drawbacks:

[0004] 1. Apply sealant between the top cover and the chassis to prevent water from seeping into the chassis or accumulating between the top cover and the chassis, which can cause the chassis to rust.

[0005] 2. To prevent water from seeping between the top cover and the chassis, sealant needs to be applied. This makes it difficult to disassemble and reassemble when replacing the top fan. Moreover, after installation, sealant needs to be applied again, which takes a long time and is inefficient on-site.

[0006] 3. The ventilation holes are only one material thickness from the chassis, making it easy for water to enter the chassis. In heavy rain, water can also easily splash inside the chassis. Utility Model Content

[0007] The purpose of this invention is to provide a reliable and durable waterproof structure for optoelectronic integrated wiring boxes.

[0008] To achieve the above objectives, the following technical solution is adopted:

[0009] A reliable and durable waterproof structure for an optoelectronic integrated wiring box is characterized in that the waterproof structure is wrapped around the top of the chassis, the waterproof structure includes a top cover and an L-shaped fixing plate, the middle of the top cover is bent upwards, both ends are bent downwards, and one end is bent into a groove shape with its edge extending to one side of the chassis, the bottom of the groove bend is provided with a ventilation hole, the ventilation hole is connected to the inside of the chassis, and the other end of the top cover is connected to the other side of the chassis through the L-shaped fixing plate.

[0010] Furthermore, one end of the top cover, which is bent into a groove shape, is fixed to the chassis with screws.

[0011] Furthermore, the chassis is provided with an irregularly shaped fastener, one side of which is bent upwards, and one end of the L-shaped fixing plate is inserted into the bend of the irregularly shaped fastener.

[0012] By adopting the above solution, the beneficial effects of this utility model are:

[0013] The system features an external waterproof structure, with the top cover completely encased outside the chassis. This effectively prevents rainwater from entering the chassis through the seams between the top cover and the chassis, ensuring efficient and reliable waterproofing. The top of the cover has a sloping design to prevent water accumulation and corrosion. The ventilation holes are located at the bottom of the sunken area, serving a drainage function. Even if splashed water enters the sunken area, it can be drained promptly, preventing water accumulation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5A reliable and durable waterproof structure for an optoelectronic integrated wiring box is characterized in that the waterproof structure is wrapped around the top of the chassis 200. The waterproof structure includes a top cover 11 and an L-shaped fixing plate 12. The middle part of the top cover 11 is bent upward, and both ends are bent downward. One end is bent into a groove shape, and its edge extends to one side of the chassis 200. A ventilation hole 111 is provided at the bottom of the bend of the groove shape. The ventilation hole 111 communicates with the inside of the chassis 200. The other end of the top cover 11 is connected to the other side of the chassis 200 through the L-shaped fixing plate 12.

[0024] The top cover 11 is bent into a groove shape at one end and fixed to the chassis 200 by screws 14.

[0025] The chassis 200 is provided with an irregularly shaped fastener 13, one side of which is bent upwards, and one end of the L-shaped fixing plate 12 is inserted into the bend of the irregularly shaped fastener 13.

[0026] This utility model adopts an external waterproof structure. The top cover 11 is completely wrapped around the outside of the chassis 200, which can effectively prevent rainwater from entering the chassis 200 through the joint between the top cover 11 and the chassis 200. The waterproof effect is efficient and reliable. The top of the top cover 11 adopts an inclined structure, which can prevent water from accumulating on the top of the top cover 11 and avoid corrosion of the top cover 11. The ventilation hole 111 is located at the lower end of the sunken trough, which can play a role in drainage. Even if splashed water enters the sunken trough, it can be discharged in time to avoid water accumulation in this area.

[0027] During installation, place the top cover 11 on the chassis 200 and push it from back to front to make the L-shaped fixing plate 12 and the irregular-shaped fixing piece 13 interlock and fix each other. Then, fix the top cover 11 to the chassis 200 through the mounting holes at the front end of the chassis 200.

[0028] In another embodiment, the L-shaped fixing plate 12 is welded to the top cover 11 and can be tenon-jointed and fixed to the irregularly shaped fixing piece 13 welded to the chassis 200. The upper part of the top cover 11 has a front-to-back inclined structure, which can effectively prevent water accumulation on the top cover 11. The irregularly shaped fixing piece 13 is fixed to the chassis 200 by welding.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
