Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a moisture-proof and humidity-proof structure of a marine junction box. Background Art

[0002] A junction box is a box used to connect and connect cables for various devices in power transmission, distribution, control, and protection systems. It is a crucial component of electrical systems, protecting electrical equipment and maintaining the safety of electricians. Existing junction boxes use a hinged connection between the door and the box body, leaving a gap between the box body and the door. The humid air and strong waves at sea make it easy for moisture and water to enter the junction box on board, causing damage to the internal electrical components. To address this problem, we have proposed a moisture-proof and humidity-resistant structure for marine junction boxes. Utility Model Content

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A moisture-proof and humidity-proof structure for a marine junction box is designed, comprising a box cover, a sealing gasket being provided on the box cover, the sealing gasket being in contact with the box body, threaded sleeves being rotatably connected on both sides of the box body via bearings, a plurality of threaded sleeves being threadedly connected with threaded columns, a plurality of threaded columns being fixedly connected to the box cover, the threaded directions of the threaded columns on both sides of the box cover being opposite, a plurality of threaded sleeves being fixedly connected with gears, a rack being meshed with the gears, and the rack being moved by a moving mechanism.

[0006] Preferably, the moving mechanism includes a threaded rod, which is rotatably connected to the box body through a bearing, and a moving plate is connected through a thread on the threaded rod, and the moving plate is fixedly connected to the rack, and the moving plate is limited by a limiting mechanism.

[0007] Preferably, the limiting mechanism includes a limiting column, the limiting column is fixedly connected to the box body, and the limiting column passes through the movable plate.

[0008] Preferably, a fixing plate is fixedly connected to the box body, two positioning columns are fixedly connected to the fixing plate, and two positioning holes are provided on the box cover, and the two positioning columns can be respectively inserted into the two positioning holes.

[0010] Preferably, a placement box is fixedly connected to the box body, and the placement box is used to place the box cover.

[0011] Preferably, a reinforcing rib is fixedly connected between the placement box and the fixing plate.

[0012] The utility model proposes a moisture-proof and humidity-proof structure for a marine junction box, which has the beneficial effects of: the rack is driven to move by a moving mechanism, thereby driving a plurality of threaded sleeves to move, so that the threaded column is moved, and the position of the threaded column in the threaded sleeve is adjusted; the box cover applies pressure to the sealing gasket to seal the box cover and the box body, thereby ensuring the sealing performance, preventing the ingress of water vapor and water, and ensuring the moisture-proof and humidity-proof effect.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1: Reference Figure 1-4 A moisture-proof and humidity-proof structure of a marine junction box includes a box cover 1, a sealing gasket is provided on the box cover 1, and a handle 7 is fixedly connected to the box cover 1 for grasping and removing the box cover 1.

[0020] The sealing gasket abuts against the box body 2, and the sealing gasket plays a role of abutting and sealing between the box body 2 and the box cover 1. A wire entry hole is provided on the box body 2. After the wire enters, it is sealed with sealant. The fixing plate 3 is fixedly connected to the box body 2 and is fixedly connected to the ship by bolts. Both sides of the box body 2 are rotatably connected to threaded sleeves 11 through bearings. Multiple threaded sleeves 11 are threadedly connected to threaded columns 12. Multiple threaded columns 12 are fixedly connected to the box cover 1. The thread directions of the threaded columns 12 on both sides of the box cover 1 are opposite. 11 are all fixedly connected with gears 10, and gears 10 are meshed with racks 9. Racks 9 are moved by a moving mechanism, and the moving mechanism drives racks 9 to move, thereby driving multiple threaded sleeves 11 to move, so that the threaded column 12 is moved, and the position of the threaded column 12 in the threaded sleeve 11 is adjusted. The box cover 1 applies pressure to the sealing gasket to seal the box cover 1 and the box body 2, ensuring the sealing, preventing the entry of water vapor and water, and ensuring the moisture-proof and humidity-proof effect. In order to ensure the dryness of the inside of the box body 1, a desiccant can be put in.

[0021] The moving mechanism includes a threaded rod 6, which is rotatably connected to the box body 2 through a bearing. A moving plate 14 is connected through a thread on the threaded rod 6. The moving plate 14 is fixedly connected to the rack 9. The moving plate 14 is limited by a limiting mechanism. When the electrical box needs to be opened for use, the position of the moving plate 14 on the threaded rod 6 is adjusted by rotating the threaded rod 6, thereby driving the rack 9 to move, which will drive the threaded sleeve 11 to rotate.

[0022] The limiting mechanism includes a limiting column 13, which is fixedly connected to the box body 2 and passes through the movable plate 14. The limiting column 13 limits the movable plate 14 and prevents the movable plate 14 from rotating.

[0023] Example 2: In Example 1, when removing and installing the box cover 1, it is necessary to align the threaded sleeve 11 with the threaded column 12 before installation, which increases the difficulty of operation. Figure 1-3 As another preferred embodiment of the present utility model, on the basis of embodiment 1, a fixing plate 3 is fixedly connected to the box body 2, two positioning columns 8 are fixedly connected to the fixing plate 3, and two positioning holes are provided on the box cover 1. The two positioning columns 8 can be respectively inserted into the two positioning holes. The positioning columns 8 and the positioning holes are used to position the box cover 1 so that the threaded sleeve 11 and the threaded column 12 are aligned.

[0024] When opening the box cover 1: by grasping the handle 7, rotating the threaded rod 6, adjusting the position of the movable plate 14 on the threaded rod 6, thereby driving the rack 9 to move, driving the threaded sleeve 11 to rotate, adjusting the position of the threaded column 12 in the threaded sleeve 11, disengaging the threaded column 12 from the threaded sleeve 11, and removing the box cover 1.

[0025] Example 3: Reference Figure 1-3 As another preferred embodiment of the present invention, on the basis of Example 2, a placement box 5 is fixedly connected to the box body 2, and the placement box 5 is used to place the box cover 1. A reinforcing rib 4 is fixedly connected between the placement box 5 and the fixed plate 3. By adopting the placement box 5, the box cover 1 can be placed after being removed.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
