[0032] The locking member 1 3 comprises a positioning block 31 fixedly connected to the outer end of the steel door panel 1, and a positioning pin shaft 32 fixedly connected to the side end of the positioning block 31;
[0033] The locking member 4 includes a base 41 fixedly connected to the outer end of the column 2, a limiting hole 42 is provided at the front end of the base 41, a limiting plate 43 is rotatably connected between the inner walls of the limiting hole 42, a top plate 44 is fixedly connected to the upper end of the limiting plate 43, a positioning member 45 is installed between the inner walls of the limiting hole 42, the positioning member 45 is located at the lower side of the limiting plate 43, and a limiting member 46 is provided inside the limiting plate 43.
[0034] During use of the present scheme, in order to make it more convenient for existing personnel to close the steel door of a ship, in the present embodiment, when the steel door panel 1 is closed, the personnel can first rotate the limit plate 43 to make the limit plate 43 no longer block the closing opening of the base 41, and then rotate the positioning pin 32 to the notch of the base 41, and then the personnel reset the limit plate 43 again to make the limit plate 43 rotate to above the positioning member 45, and at the same time, on one side of the positioning pin 32, limit the positioning pin 32 to make the steel door panel 1 unable to continue to rotate, and then the personnel press the limit member 46 to make the limit member 46 engage with the surface of the positioning member 45, thereby completing the limitation of the limit plate 43 and making it unable to rotate, so as to achieve the closed locking of the steel door panel 1.
[0035] See also Figure 1-3 The positioning member 45 includes a base 2 451 fixedly connected between the inner bottom walls of the limiting hole 42, a connecting rod 1 452 is fixedly connected to the upper end of the base 2 451, a connecting rod 2 453 is fixedly connected to the upper end of the connecting rod 1 452, a positioning ring 454 is sleeved on the outer end of the connecting rod 2 453, and a hemisphere 455 is fixedly connected to the top of the connecting rod 2 453.
[0036] More specifically: a receiving groove 431 is provided at the bottom end of the limiting plate 43, the limiting member 46 includes a limiting sleeve 461 provided inside the receiving groove 431, a receiving groove 462 is provided at the bottom end of the limiting sleeve 461, two symmetrically distributed limiting members 463 are installed on the side ends of the receiving groove 462, a connecting rod 3 464 is fixedly connected to the upper end of the limiting sleeve 461, the connecting rod 3 464 passes through the top of the top plate 44, a spring 2 465 is fixedly connected between the limiting sleeve 461 and the top wall of the receiving groove 431, the spring 2 465 is sleeved on the outside of the connecting rod 3 464, and a connecting block 466 is fixedly connected to the upper end of the connecting rod 3 464.
[0037] More specifically, the positioning ring 454 is composed of two mirror-image frustums, and the interior of the hemisphere 455 is hollow.
[0038] During the use of this solution, when the personnel need to close and lock the steel door panel 1, after the limit plate 43 is located on one side of the positioning pin shaft 32 to limit it, the connecting block 466 can be pressed, so that the limit sleeve 461 is continuously moved downward, and the spring 2 465 is stretched by force until the limit pieces 463 on both sides are located on the lower side of the hemispherical body 455 under the resistance. When the personnel no longer press the connecting block 466, under the reset characteristic when the spring 2 465 is not under force, the limit piece 2 463 is limited to the lower side of the hemispherical body 455 to be locked, so that the limit plate 43 as a whole can no longer continue to rotate at this time, and the positioning pin shaft 32 is prevented from falling out of the notch at the base 1 41;
[0039] When the personnel need to release the limit and open the steel door panel 1, the personnel can continue to press the connecting block 466 downward, so that the limiting sleeve 461 continues to move downward, and again presses against the positioning ring 454 to prompt the limiting member 2 463 to be located under the table below the positioning ring 454. Then the personnel no longer presses against the connecting block 466, so that the positioning ring 454 is hooked upward under the action of the resetting spring 2 465, and until the upper positioning ring 454 is located inside the hemisphere 455, at this time, the limiting sleeve 461 slides on the surface of the hemisphere 455 and no longer engages with its surface. Therefore, the personnel can rotate the limiting plate 43 again to open and close the steel door panel 1.
[0040] See also Figure 1-5 The second limiting member 463 includes a built-in cavity 4631 opened inside the limiting sleeve 461, a connecting rod 4632 is inserted into the inside of the built-in cavity 4631, one end of the connecting rod 4632 passes through the outside of the limiting sleeve 461, the other end of the connecting rod 4632 is fixedly connected to the limiting block 4634, and the limiting block 4634 passes through the inner side of the limiting sleeve 461, and a spring 4633 is fixedly connected between the front and rear inner walls of the built-in cavity 4631, and the spring 4633 is sleeved on the outside of the connecting rod 4632.
[0041] During use of the present solution, when the limiting sleeve 461 is moving downward, the limiting block 4634, due to its bottom being an inclined surface, contacts the hemispherical body 455 below, and the limiting block 4634 is forced to be accommodated in the built-in cavity 4631, and presses the spring 1 4633, causing it to be compressed. Then, when the position is at the lower side of the hemispherical body 455, the limiting block 4634 rebounds again under the action of the spring 1 4633 without being forced, so that it is engaged with the lower side of the hemispherical body 455 and cannot continue to move upward, thereby limiting the position of the limiting plate 43.
[0042] When the personnel need to release the position limit of the limit plate 43, they can further press the limit plate 43 to force the limit block 4634 to pass over the top of the positioning ring 454 again and be stored until it is located on the lower side of the hemisphere 455 and then pops out. At this time, the positioning ring 454 is driven by the support of the limit block 4634 and the rebound of the spring 2 465 until it is located inside the hemisphere 455. At this time, the positioning ring 454 of the lower side cone contacts the outer arc surface of the hemisphere 455, and the limit block 4634 is located above the hemisphere 455 under continuous upward movement and resistance, completing the unstuck phenomenon. After that, the positioning ring 454 falls again to the top of the connecting rod 1 452 under the action of gravity.
[0043] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
