Technical Field

[0001] The utility model relates to the technical field of electrical box auxiliary devices, in particular to a ship electrical box door cover limiting support device. Background Art

[0002] A ship is a man-made means of transportation that mainly operates in geographical waters. Its interior mainly includes a storage space, a supporting structure, and a drainage structure. It has a propulsion system that utilizes external or self-provided energy. There are many electrical boxes on the ship that require watertightness. They need to be opened during use and closed immediately after use. As the service life of the electrical box increases, the electrical box needs to be maintained and inspected regularly. When maintaining and inspecting the electrical box, it is necessary to ensure that the electrical box cover is in an open state to ensure the maintenance and inspection of the electrical box.

The telescopic spring, the first connecting rod, the first sliding block, the first support rod, the support plate, the second support rod and the connecting plate can play a good supporting effect when the protective door is opened, thereby preventing the protective door from shaking after opening. Subsequently, a second connecting rod and a second sliding block are provided, and the second connecting rod and the second sliding block can play a certain limiting effect when the first sliding block slides on the outer surface of the first connecting rod.

[0004] Although the above-mentioned device can provide good support when the protective door is opened and can limit the position by setting a telescopic spring, a first connecting rod, a first sliding block, a first support rod, a support plate, a second support rod and a connecting plate, the electrical box door cover sometimes opens automatically due to a collision, thereby damaging the internal structure. While limiting the opening process, it is also necessary to ensure that when closing, the automatic door opening phenomenon caused by some additional conditions can be prevented. For this reason, we propose a new type of ship electrical box door cover limit support device. Utility Model Content

[0027] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a ship electrical box door cover limit support device, installed on the electrical box 2, including:

[0028] A door cover 1 is installed at one end of the electrical box 2;

[0029] A corner mechanism 3 is arranged at the bottom inner side of the electrical box 2 and is used to assist the door cover 1 in rotating;

[0030] The limiting mechanism 4 is arranged on the inner side of the door cover 1 and is used for limiting the position of the door cover 1 during the opening and closing process.

[0031] The corner mechanism 3 comprises:

[0032] A base 309 is installed at the bottom inner side of the electrical box 2. Fixing bolts 304 are installed around the base 309. A fixing column 406 is installed at the top of the base 309. A connecting rod 302 is installed on the outer wall of the fixing column 406. A limiting plate 301 is installed on the top of the connecting rod 302. The limiting plate 301 is located on the outer wall of the top of the fixing column 406.

[0033] The limiting mechanism 4 comprises:

[0034] A moving bar hole 402 is set in the door cover 1, and limiting blocks 401 are installed at both ends of the moving bar hole 402. A moving strip plate 413 is installed on the inner side of the moving strip hole 402, and a stair seat 403 is installed on the outer side of the moving strip plate 413. A first fixed plate 404 is installed on one end of the stair seat 403 through a fixed column 406, and a first limiting groove 407 is set on the first fixed plate 404.

[0035] A rotating bolt 305 is installed at the other end of the connecting rod 302, and a rotating rod 303 is installed on the outer wall of the rotating bolt 305. The rotating rod 303 is located at the top of the connecting rod 302. A transmission rod 306 is installed on the inner side of the other end of the rotating rod 303. The other end of the transmission rod 306 is installed on the inner side of the adapter 307. An electric push rod 308 is installed at one end of the adapter 307.

[0036] like Figure 2 As shown, it should be noted that: when the door cover 1 rotates, the transmission rod 306 at the other end of the adapter 307 is driven to move by the electric push rod 308, and the transmission rod 306 drives the rotating rod 303 to rotate during the movement, and the rotating rod 303 drives the connecting rod 302 to move during the rotation, thereby assisting the door cover 1 to perform the switch operation on the electrical box 2.

[0037] A mounting seat 418 is installed at the top of the stair seat 403, a second fixing plate 410 is installed at one end of the mounting seat 418 through a fixing column 406, a second limiting groove 409 is provided on the second fixing plate 410, a sliding plate 419 is installed at the top of the mounting seat 418, and a sliding groove 412 is provided on one side of the sliding plate 419.

[0038] A guide rail 414 is installed on the inner side of the sliding groove 412, a sliding block 411 is installed on the outer side of the guide rail 414, a connecting plate 415 is installed on the bottom end of the sliding block 411, a rotating bolt 305 is installed on the other end of the connecting plate 415, a moving plate 417 is installed on the outer wall of the rotating bolt 305, a fixing rod 408 is installed on one end of the moving plate 417, and a first rolling wheel 405 and a second rolling wheel 416 are staggeredly installed on both sides of the fixing rod 408 through the rotating bolt 305.

[0039] like Figure 3 As shown, it should be noted that: when the door cover 1 is in the closed state, the first rolling wheel 405 is located in the first limiting groove 407, and the second limiting groove 409 is located at a position slightly to the right above the first limiting groove 407. At this time, since the first rolling wheel 405 is restricted in the first limiting groove 407, the door cover 1 can be limited to ensure that the door cover 1 and the electrical box 2 are in contact. When the door cover 1 is to be opened, the handle on the door cover 1 is held and the corner mechanism 3 is used to drive the door cover 1 to rotate. At this time, the electric push rod 308 drives the mounting seat 418 to move in the moving strip hole 402 through the moving strip plate 413. During the movement, the second limiting groove 409 on the mounting seat 418 When it is located directly above the first limiting groove 407, the second rolling wheel 416 enters the second limiting groove 409. At this time, the electric push rod 308 continues to drive the mounting seat 418 to move, and the first rolling wheel 405 comes out of the first limiting groove 407. Then the first rolling wheel 405 moves on the stair seat 403. At this moment, the second rolling wheel 416 is completely installed in the second limiting groove 409, and the second rolling wheel 416 fits with the inner wall of the second limiting groove 409. Even if the second rolling wheel 416 moves forward or backward on the stair seat 403, the second rolling wheel 416 will not be detached, so the door cover 1 is supported and limited, thereby preventing the corner mechanism 3 from rotating.

[0040] To sum up, the ship electrical box door cover limit support device can support and limit the door cover 1 by arranging the first rolling wheel 405 and the second rolling wheel 416 to move in the first limit groove 407 and the second limit groove 409 respectively. The electric push rod 308 drives the mounting seat 418 to move, which can stagger the limiting work of the first rolling wheel 405 and the second rolling wheel 416, and can ensure that the door cover 1 can be limited and supported in both states when opening and closing, thereby improving the practicability of the device, avoiding the automatic opening of the door cover 1 due to emergencies, and improving the utilization rate of the device.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
