Description

Technical Field

[0001] This utility model relates to the field of waterproof box technology, specifically a waterproof box. Background Technology

[0002] Outdoor electrical installation typically involves the installation of various electrical devices. Most of these devices require high levels of waterproofing, but these devices themselves cannot adequately meet these requirements. Therefore, additional waterproofing equipment is necessary to achieve their waterproofing function.

[0003] A waterproof box, as disclosed in authorization announcement number CN205320419U, includes a box body for housing electrical components, a box cover that mates with the box body, and a locking device for locking the box cover to the box body. The beneficial effects of this utility model, achieved by adopting the above technical solution, are: it can effectively realize the positioning and installation function while ensuring the waterproof effect of the electrical components inside the box.

[0004] While the aforementioned patent provides quick installation and positioning and a simple locking structure, it lacks an elastic sealing element between the lid and the body, relying solely on the locking device to achieve a rigid "hard contact" closure. This structure makes it difficult to form a uniform and effective sealing pressure on the joint surface, resulting in an inability to reliably compensate for the processing deformation of the body itself or the vibration and impact during use, and it is very easy to generate tiny gaps at the joint. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0010] Preferably, the magnetic attraction mechanism includes limiting rods fixedly connected to the upper two sides of the inner wall of the four sides of the box, and waist-shaped holes opened at both ends of the four sides of the sealing frame. The limiting rods are slidably connected to the waist-shaped holes. A frame groove is opened at the bottom of the box cover. A frame-shaped magnet is fixedly connected to the inner top wall of the frame groove. A magnetic plate that cooperates with the frame-shaped magnet is embedded in the upper part of the four sides of the sealing frame.

[0011] Preferably, the locking mechanism includes a locking seat fixedly connected to the lower surface of the box cover, and a flip groove formed below the center of the four sides of the locking seat. The interior of the flip groove is rotatably connected to a rotating shaft via a bearing. A limiting claw is fixedly connected to the bottom end of the rotating shaft. A bottom groove is formed below the center of the four sides of the sealing frame strip. Limiting plates are fixedly connected to the upper and lower ends of the bottom grooves on the inner wall of the box body.

[0024] 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.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution:

[0026] A waterproof box includes a box body 1 with a box cover 2 at its top. A locking mechanism is provided between the box cover 2 and the box body 1. The locking mechanism includes a locking seat 9 fixedly connected to the lower surface of the box cover 2, and a flip groove 10 formed below the center of the four sides of the locking seat 9. A rotating shaft 11 is rotatably connected to the inside of the flip groove 10 via bearings. A limiting claw 12 is fixedly connected to the bottom end of the rotating shaft 11. Bottom grooves 13 are formed below the center of the four sides of the sealing frame 3. Limiting plates 14 are fixedly connected to the upper and lower ends of the bottom grooves 13 on the inner wall of the box body 1, respectively. The thickness of the limiting claw 12 matches the distance between the two limiting plates 14, and the width of the limiting claw 12 is greater than the width of the limiting plates 14. Small gears 15 are rotatably connected to the four sides of the inside of the box cover 2 via bearings. A small gear 15 is rotatably connected to the center of the inner side of the box cover 2 via bearings. A large gear 16 meshes with four small gears 15. The top end of the rotating shaft 11 is fixedly connected to the small gears 15. A circular hole 17 is opened in the middle of the top of the box cover 2. A knob 18 is rotatably connected to the middle of the circular hole 17 through a sealed bearing. The bottom end of the knob 18 is fixedly connected to the large gear 16. A sealing frame 3 is set on the upper inner wall of the box body 1. A magnetic attraction mechanism is set between the box cover 2 and the sealing frame 3. The magnetic attraction mechanism includes a limiting rod 4 fixedly connected to the upper two sides of the inner wall of the four sides of the box body 1, and an oblong hole 5 opened at both ends of the four sides of the sealing frame 3. The limiting rod 4 is slidably connected to the oblong hole 5. A frame groove 6 is opened at the bottom of the box cover 2. A frame magnet 7 is fixedly connected to the inner top wall of the frame groove 6. A magnetic plate 8 that works with the frame magnet 7 is embedded in the upper part of the four sides of the sealing frame 3.

[0027] In this embodiment, by using the magnetic attraction mechanism in conjunction with the limiting rod 4 and the waist-shaped hole 5, the sealing frame strip 3 can be automatically attracted and lifted when the box cover 2 is closed, so that it fits tightly against the upper part of the inner wall of the box body 1 to form an initial seal, which solves the problem of poor initial sealing caused by the lack of effective pre-tightening force in traditional structures.

[0028] Through the coordinated action of the locking mechanism and the magnetic attraction mechanism, the limiting claw 12 provides a stable mechanical support for the sealing frame strip 3 that is lifted by the magnetic attraction force, and together maintains the compression state of the sealing material, thus solving the problem of sealing failure caused by vibration or deformation.

[0029] Working principle: Rotating knob 18 drives the large gear 16 to rotate 90 degrees clockwise. The large gear 16 simultaneously drives four small gears 15 to rotate. The small gears 15, through shaft 11, drive the limiting pawl 12 to rotate, causing the limiting pawl 12 to disengage from the two limiting plates 14, thus releasing the lock between the cover 2 and the body 1. Simultaneously, the limiting pawl 12 releases its limiting support on the lower part of the sealing frame strip 3. When the cover 2 is opened, as it is lifted, the magnetic attraction between the frame magnet 7 and the magnetic plate 8 rapidly weakens and disappears. The upper inner wall of the oblong hole 5 is blocked by the limiting rod 4, ensuring that the sealing frame strip 3 does not move with the cover 2. The lid is lifted to reliably detach from the cover 2. When the cover 2 is closed, the cover 2 moves the frame magnet 7 close to the magnetic plate 8. The magnetic attraction overcomes gravity and pulls the sealing frame strip 3 up and into the frame groove 6, so that its bottom is higher than the limiting plate 14. Then, the reverse knob 18 is driven by the large gear 16, the small gear 15 and the rotating shaft 11, so that the limiting claw 12 rotates between the two limiting plates 14 and is supported on the sealing frame strip 3 and close to the lower sides of the bottom groove 13. At this time, the sealing frame strip 3 is tightly attached to the upper part of the inner wall of the box 1 under the combined action of the top magnetic attraction and the bottom mechanical support, forming a stable seal, and finally achieving a reliable waterproof effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
