Description

Technical Field

[0001] This utility model belongs to the field of electrical technology, specifically relating to an electrical waterproof box. Background Technology

[0002] In the field of electrical engineering, waterproof boxes are key components protecting electrical elements such as sockets and switches, and their performance directly affects the safety, waterproofing effect, and service life of the equipment. Traditional waterproof boxes are usually made of plastic, which, while possessing a certain degree of waterproofing capability, has significant deficiencies in corrosion resistance, mechanical strength, and durability. To address this issue, some existing waterproof covers use metal to improve their corrosion resistance, mechanical strength, and durability. However, the hinged structure design between the metal waterproof cover and the mounting frame faces challenges: typically, a thin metal sheet is spot-welded to the inside of the waterproof cover, and hinge holes are provided on the metal sheet. The hinge axis on the mounting frame is hinged to the hinge holes. However, this design has significant drawbacks in practical applications: the welded points may crack due to stress concentration or corrosion during long-term use, affecting the stability of the hinged structure. Utility Model Content

[0003] The purpose of this utility model is to provide an electrical waterproof box, which improves structural stability by optimizing its hinge structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] The electrical waterproof box structure of this utility model embodiment is as follows: Figures 1 to 6 As shown, the structure includes a mounting frame 1 and a waterproof cover 2. The mounting frame 1 has a socket / switch mounting position 11, which can be used to install a socket 3 or a switch. The upper end of the waterproof cover 2 is connected to the upper end of the mounting frame 1 by a hinge structure, and the waterproof cover 2 is opened and closed by flipping it. The hinge structure includes a hinge shaft 12 mounted on the mounting frame 1 and a bushing 21 provided on the waterproof cover 2, with the bushing 21 sleeved on the hinge shaft 12. The waterproof cover 2 is made of metal, and the bushing 21 is bent and integrally formed with the waterproof cover 2. In this embodiment, the bushing 21 and the waterproof cover 2 are designed to be integrally formed, which effectively avoids the potential problems of traditional welding schemes and significantly improves the performance of the structure. Specifically, welding processes, due to the existence of a heat-affected zone, may cause local deformation of the material, stress concentration, or welding defects (such as porosity, cracks, etc.), thereby weakening the overall strength and durability of the structure. The one-piece molding process not only eliminates the weak points of the welding interface, but also ensures a seamless connection between the bushing 21 and the waterproof cover 2, improving the reliability and service life of the product.

[0027] In a preferred embodiment, the mounting frame 1 is provided with a hinge shaft hole 13 and a stop structure. One end of the hinge shaft 12 is provided with a stop portion 14. The hinge shaft 12 and the hinge shaft hole 13 are inserted into each other. The stop structure cooperates with the stop portion 14 to restrict the hinge shaft 12 from exiting the hinge shaft hole 13. That is, the hinge shaft 12 is limited by the insertion design of the hinge shaft hole 13 and the hinge shaft 12, and the cooperation of the stop structure and the stop portion 14. This method simplifies the assembly process of the hinge structure, improves its stability and durability, and provides a reliable guarantee for the long-term stable operation of the waterproof box.

[0028] See Figure 3 and Figure 4 To further simplify the structure, the stop part 14 is formed by bending the end of the hinge shaft 12, and the stop structure is a stop groove 15 provided on the mounting frame 1. The stop part 14 is confined within the stop groove 15, thereby axially limiting the hinge shaft 12. This ensures that the hinge shaft 12 will not move axially and loosen during use. Moreover, the bend-formed stop part 14 and the stop groove 15 have a simple and reliable fit, reducing manufacturing costs and improving production efficiency.

[0029] Continue reading Figure 3 and Figure 4 A pressure plate 16 is fixed on the mounting frame 1. The pressure plate 16 blocks and restricts the stop part 14 within the stop groove 15, thereby limiting the hinge shaft 12 and preventing the stop part 14 from exiting the stop groove 15, thus ensuring the reliability of the hinge shaft 12 installation.

[0030] Combination Figures 2 to 4 To enhance the stability of the waterproof cover installation, two hinge shafts 12 are installed on the mounting frame 1, with the stop portions 14 of the two hinge shafts 12 close to each other. Corresponding to the stop portions 14, the mounting frame 1 is provided with two stop grooves 15. A pressure plate 16 covers both stop grooves 15 simultaneously and forms a limiting stop on the two stop portions 14. By covering and fixing the pressure plate 16 on the two stop grooves 15, the two stop portions 14 are effectively limited and stopped, thereby preventing the hinge shafts 12 from accidentally exiting from the hinge shaft holes 13, ensuring that the hinge shafts 12 always maintain a stable position during use, and improving the stability of the structure.

[0031] See Figure 3 and Figure 4To ensure that the pressure plate 16 is reliably positioned on the mounting frame 1, a protruding positioning post 17 and a screw hole 18 are further provided on the mounting frame 1. The pressure plate 16 is provided with a positioning insertion hole 161 and a screw through hole 162. When installing the pressure plate 16, the positioning is initially positioned by inserting it into the positioning post 17 through the positioning insertion hole 161. Then, a fastening screw (not shown in the figure) is used to screw through the screw through hole 162 and into the screw hole 18 to ensure that the pressure plate 16 is tightly connected to the mounting frame 1.

[0032] See Figure 1 The surface of the pressure plate 16 is covered with a sealing gasket 19, which can cover the gap between the pressure plate 16 and the mounting frame 1 to provide a sealing and protection function. Moreover, compared with the gap between the pressure plate 16 and the mounting frame 1, the positioning hole 161 and the exposed part of the fastening screw, the overall structure is simpler and more beautiful, combining practicality and decoration.

[0033] Continue reading Figure 1 The mounting frame 1 has a drainage groove 10 on the outside of the socket / switch mounting position 11, and a drain outlet is provided at the lower end of the drainage groove 10; a water-blocking strip 110 is formed between the drainage groove 10 and the socket / switch mounting position 11; the drainage groove 10 is located on the outside of the socket / switch mounting position 11, and its lower end is provided with a drain outlet, the main function of which is to collect and guide water that seeps in from the outside; the water-blocking strip 110 is located between the drainage groove 10 and the socket / switch mounting position 11, and plays the role of blocking water flow.

[0034] like Figure 1 and Figure 2 As shown, the waterproof cover 2 has a wire passage 22 at its lower end, so that the waterproof cover 2 can be closed when the external plug is plugged into the socket, and the wire connected to the plug is led out through the wire passage 22.

[0035] As a preferred embodiment, a sealing ring is provided on the rear surface of the mounting frame 1. When the electrical waterproof box is installed on the mounting surface, the sealing ring is pressed between the mounting frame 1 and the mounting surface to form an effective seal, preventing water from entering through the gap between the mounting frame 1 and the mounting surface.

[0036] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the scope of protection of this invention.
