Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a reinforced support frame for a distribution box with multi-layer protection. Background Technology

[0002] When reinforcing the support frame of a multi-layered protected distribution box, a multi-layered protective distribution box reinforcement support frame is often used. This product is designed to strengthen the distribution box structure. By adding multi-layered protective structures and reinforcing support components, it provides the distribution box with more stable physical support and more comprehensive protection. Its advantages include significantly improving the stability of the distribution box in complex environments or when subjected to external impacts, reducing the risk of damage to internal electrical components due to vibration, collisions, etc. At the same time, multi-layered protection can enhance the resistance to dust, moisture, electromagnetic interference, etc., ensuring the normal operation and use of electrical equipment inside the distribution box.

[0003] The multi-layered protection distribution box is reinforced with a support frame. The structure of each layer of protection and the layout of the support frame are determined. Appropriate materials are selected to build the main frame and the protective components of each layer. Then, the protective layers and the support frame are precisely combined and installed. After that, debugging and testing are carried out to check the function of each protective layer and the stability of the frame. Finally, it is put into use and regularly maintained to ensure that it continues to play its role in multi-layered protection and reinforcement.

[0004] Existing technologies include multi-layered protective reinforced support frame devices for distribution boxes. However, traditional support frame structures are simple and cannot meet the reinforcement requirements of distribution boxes in complex environments. When encountering extreme situations such as earthquakes or strong winds, the support frame cannot provide sufficient stable support for the distribution box, which can easily lead to the distribution box tipping over or being damaged, thereby affecting the normal operation of the power supply. On the other hand, the existing support frames have poor protective performance and lack effective waterproof, dustproof, and impact-resistant protective measures. They cannot resist the intrusion of external rainwater and dust, as well as the damage to the internal electrical components of the distribution box caused by accidental collisions, thus reducing the service life and operational reliability of the distribution box. Therefore, a multi-layered protective reinforced support frame for distribution boxes is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a reinforced support frame for a distribution box with multi-layer protection, aiming to improve the problem that some existing devices cannot provide reinforced support and protection for the distribution box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A reinforced support frame for a distribution box with multi-layer protection includes a distribution box body, a door fixedly connected to the outer right side of the distribution box body, a reinforced support mechanism inside the distribution box body, and a protective mechanism at the bottom of the distribution box body.
