Description

Technical Field

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

[0002] In the field of electrical engineering and electronic equipment, junction boxes are an important electrical connection component, widely used for the connection, branching, and protection of various circuits.

[0003] Junction box structures typically use bolted connections to secure the box body and cover. While simple and reliable, this method has significant waterproofing drawbacks. In real-world environments, junction boxes may be exposed to outdoor or damp conditions, such as building exteriors, basements, and industrial workshops. In these environments, rainwater, moisture, or accidental splashes can easily seep into the junction box through the bolt holes. Once moisture enters the junction box, it can cause short circuits and corrosion of electrical components, affecting the normal operation of the entire circuit system and even leading to safety accidents. Therefore, a waterproof junction box structure is proposed to address these issues. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a junction box structure with waterproof performance, which has the advantages of preventing water from seeping into the box body through the bolt holes, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waterproof junction box structure includes a box body and a box cover. Connecting plates are fixedly connected to both sides of the box cover, and a connecting component for connecting to the box cover is provided at the bottom of the box body.

[0007] The connecting assembly includes a bottom frame fixedly connected to the bottom of the box body. A rotating wheel is provided on the inner side of the bottom frame. Threaded shafts are fixedly connected to both the left and right sides of the rotating wheel. Threaded blocks are threadedly connected to the outer side of the threaded shafts.

[0008] Furthermore, the top of the inner side of the box has an opening, and the bottom of the box cover is fixedly connected with a sealing gasket that matches the opening.

[0009] Furthermore, a water-guiding block is fixedly connected to the top of the box cover, and water-guiding plates are fixedly connected to the opposite sides of the connecting plates on both the left and right sides. The surfaces of the water-guiding block and the water-guiding plates are coated with a hydrophobic coating.

[0010] Furthermore, wiring holes are present on both the front and rear sides of the box body, and a partition is fixedly connected between the front and rear inner side walls of the box body, with the two partitions located on the left and right sides of the wiring holes, respectively.

[0011] Furthermore, a desiccant is placed between the left-side partition and the inner left side wall of the box, and a desiccant is also placed between the right-side partition and the inner right side wall of the box. An adsorption port is provided on the inner side of the partition.

[0012] Furthermore, a frame door is hinged to the front of the bottom frame, and a rubber sleeve is fixedly connected to the outer side of the rotating wheel. The top of the rubber sleeve is in contact with the inner top wall of the bottom frame, and the bottom of the rubber sleeve is in contact with the inner bottom wall of the bottom frame.

[0013] Furthermore, the left end of the threaded shaft on the left is rotatably connected to the inner left side wall of the bottom frame, and the right end of the threaded shaft on the right is rotatably connected to the inner right side wall of the bottom frame.

[0021] 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.

[0022] Please see Figures 1 to 3 The junction box structure with waterproof performance in this embodiment includes a box body 1 and a box cover 2. Connecting plates 3 are fixedly connected to both the left and right sides of the box cover 2. The bottom of the box body 1 is provided with a connecting component for connecting with the box cover 2.

[0023] Please see Figure 1 In this embodiment, the connecting component includes a bottom frame 4 fixedly connected to the bottom of the box 1. A rotating wheel 5 is provided on the inner side of the bottom frame 4. Threaded shafts 6 are fixedly connected to both the left and right sides of the rotating wheel 5. Threaded blocks 7 are threadedly connected to the outer side of the threaded shafts 6. Locking shafts 8 are fixedly connected to the opposite sides of the threaded blocks 7 on both the left and right sides.

[0024] Specifically, the top of the inner side of the box body 1 has a box opening, and the bottom of the box cover 2 is fixedly connected with a sealing gasket 9 that matches the box opening.

[0025] It should be noted that the sealing gasket 9 is designed to provide a good seal when the cover 2 and the body 1 are closed, filling the gap between the cover 2 and the opening of the body 1, preventing moisture from seeping into the junction box through this gap, and ensuring the waterproof performance of the junction box.

[0026] Specifically, a water guide block 10 is fixedly connected to the top of the cover 2, and water guide plates 11 are fixedly connected to the opposite sides of the left and right connecting plates 3. The surfaces of the water guide block 10 and the water guide plate 11 are coated with a hydrophobic coating.

[0027] It should be noted that the design of the water guide block 10 and the water guide plate 11 guides the direction of water flow, allowing water falling on the junction box to flow away quickly along the water guide block 10 and the water guide plate 11, preventing water from accumulating on the surface of the junction box. The application of the hydrophobic coating further enhances the water guiding effect, reduces the adhesion between water and the surfaces of the water guide block 10 and the water guide plate 11, and reduces the time water stays on the surface, thereby reducing the risk of water seeping into the junction box.

[0028] Specifically, wiring holes are present on both the front and rear sides of the box body 1. A partition 12 is fixedly connected between the front and rear inner walls of the box body 1. The two partitions 12 are located on the left and right sides of the wiring holes, respectively. A desiccant 13 is placed between the left partition 12 and the inner left wall of the box body 1, and a desiccant 13 is also placed between the right partition 12 and the inner right wall of the box body 1. An adsorption port is provided on the inner side of the partition 12.

[0029] It should be noted that the desiccant 13 can absorb any moisture that may be present inside the box, maintaining a dry environment inside the box. The adsorption port on the partition 12 facilitates full contact between the desiccant 13 and the air inside the box, improving the moisture absorption effect and ensuring the normal operation of the electronic components inside the junction box.

[0030] Specifically, a frame door is hinged to the front of the bottom frame 4, and a rubber sleeve 14 is fixedly connected to the outside of the rotating wheel 5. The top of the rubber sleeve 14 is in contact with the inner top wall of the bottom frame 4, and the bottom of the rubber sleeve 14 is in contact with the inner bottom wall of the bottom frame 4.

[0031] It should be noted that the frame door on the front of the base frame 4 facilitates the maintenance and operation of the connecting components inside the base frame 4, such as rotating the rotating wheel 5. The rubber sleeve 14 also increases the friction of the rotating wheel 5, enabling the rotating wheel 5 to maintain a relatively stable position after rotation, preventing the rotating wheel 5 from rotating on its own due to external vibrations or other factors, thereby affecting the locking state of the locking shaft 8.

[0032] Specifically, the left end of the left threaded shaft 6 is rotatably connected to the inner left side wall of the bottom frame 4, and the right end of the right threaded shaft 6 is rotatably connected to the inner right side wall of the bottom frame 4.

[0033] Specifically, the inner side of the connecting plate 3 is provided with a locking hole that matches the locking shaft 8, and the left and right sides of the inner side of the bottom frame 4 are provided with through holes that match the locking shaft 8, and the through holes are connected to the corresponding locking holes.

[0034] It should be noted that the through hole provides a channel for the locking shaft 8 to enter the locking socket inside the connecting plate 3 from inside the bottom frame 4. When the locking shaft 8 passes through the through hole and is inserted into the locking socket, it can firmly connect the cover 2 and the box body 1 together, preventing the cover 2 from being opened accidentally. It also avoids the problem of water seepage in the bolt holes that may exist due to the traditional bolt connection method, thus improving the waterproof performance of the junction box.

[0035] The working principle of the above embodiments is as follows:

[0036] Place the lid 2 on top of the box body 1, ensuring the sealing gasket 9 at the bottom of the lid 2 fits tightly against the opening at the top of the box body 1. Then, manually rotate the wheel 5. As the wheel 5 rotates, it drives the threaded shafts 6 on both sides to rotate synchronously. When the threaded shafts 6 rotate, the threaded block 7, which is threaded to the threaded shaft 6, moves along the axial direction of the threaded shaft 6. As the threaded block 7 moves, the locking shaft 8, which is fixedly connected to one side of the threaded block 7, also moves accordingly. The locking shaft 8 is inserted into the locking socket on the inner side of the connecting plate 3 through the through hole on the inner side of the bottom frame 4. Once the locking shaft 8 is fully inserted into the locking socket, the lid 2 is fixedly connected to the box body 1. During the connection between the lid 2 and the box body 1, since the traditional bolt connection method is not used, there are no bolt holes, thus avoiding the problem of water seeping in through bolt holes. At the same time, the sealing gasket 9 at the bottom of the lid 2 seals the gap between the lid 2 and the box body 1, further preventing water from seeping in.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
