At present, the internal locking devices of door covers at the entrances and exits such as steel doors and small hatch covers on ships are generally locked by steel latches. Since the hull is often impacted by water and shakes during navigation, the hatches and hatch covers locked by latches are easily caused to collide with the door frames and produce noise due to loose locking and long-term collisions. In addition, the contact between the hatch cover and the door frame may be damaged. Utility Model Content

[0028] The utility model provides a marine hatch cover locking mechanism, see Figure 1-3 , including a cover plate 100, a locking component 200 and an adjusting component 300;

[0029] Please continue reading Figure 1-3 , as a cover plate 100 connected to the base frame, the front end of the cover plate 100 is integrally formed with a protrusion, and the door frame 110 cooperates with the cover plate 100 to limit the end of the cover plate 100. The door frame 110 has a groove (not marked in the figure) at the position corresponding to the end of the cover plate 100. After the cover plate 100 and the door frame 110 are covered, the front end protrusion of the cover plate 100 is just located in the groove;

[0030] The outer side of the door frame 110 is connected to a limiting seat 111, which is arranged corresponding to the front end of the handle 320 and cooperates with the handle 320 to fix the position of the cover plate 100 and the door frame 110, that is, when the handle 320 is rotated to contact the limiting seat 111, the cover plate 100 and the door frame 110 are locked;

[0031] Please continue reading Figure 1-2 , the locking component 200 is placed on the cover plate 100, locking the cover plate 100 and the door frame 110 to close the hatch position;

[0032] The locking component 200 includes a locking nut 210 embedded in the inner side of the cover plate 100, and a locking bolt 220 threadedly engaged with the locking nut 210. The locking bolt 220 passes through the bottom of the locking nut 210, and the bottom end of the locking bolt 220 is connected to a connecting rod 221.

[0033] The locking nut 210 is fixed in position. When the adjusting component 300 rotates the locking bolt 220, the locking bolt 220 moves along the inner side of the locking nut 210 under the action of the thread, thereby locking the cover plate 100 and the door frame 110.

[0034] Please continue reading Figure 1-2 The adjusting component 300 is connected to the locking component 200 to adjust the opening and closing state between the cover plate 100 and the door frame 110;

[0035] The adjusting component 300 includes a sleeve 310 threadedly connected to the outside of the connecting rod 221, the sleeve 310 drives the connecting rod 221 to move synchronously, and a handle 320 is clamped at the center of the sleeve 310;

[0036] The handle 320 drives the sleeve frame 310 to rotate, and then drives the connecting rod 221 and the locking bolt 220 to rotate, and cooperate with the locking nut 210 to achieve the locking opening and closing operation;

[0037] Please continue reading Figure 3 In order to facilitate the protection of the cover plate 100, an auxiliary component 400 is connected to the groove of the door frame 110. The auxiliary component 400 includes a sleeve 410 connected to the inner side of the groove of the door frame 110. The sleeve 410 is movably connected to a movable rod 411. The bottom of the movable rod 411 is connected to a compression spring 420. The bottom end of the compression spring 420 contacts the door frame 110.

[0038] Action 1:

[0039] When the cover plate 100 is closed, the front end of the cover plate 100 presses the movable rod 411, so that the movable rod 411 and the compression spring 420 are in a compressed state. The movable rod 411 and the compression spring 420 play a buffering role, which can effectively prevent the cover plate 100 from directly hitting the door frame 111, causing damage to both.

[0040] Action 2:

[0041] When the cover 100 is opened, the compression spring 420 releases its elastic potential energy, driving the movable rod 411 to lift the cover 110, thereby facilitating the opening and closing operation of the cover 100.

[0042] When the locking bolt 220 is actuated, the locking bolt 220 will move along the inner side of the locking nut 210 under the action of the thread, and when the handle 320 is rotated to contact the limit seat 111, the cover plate 100 and the door frame 110 are locked, which is simple and convenient to operate. In addition, when the cover plate 100 is closed, the front end of the cover plate 100 presses the movable rod 411, so that the movable rod 411 and the compression spring 420 are in a compressed state. The movable rod 411 and the compression spring 420 play a buffering role, which can effectively prevent the cover plate 100 from directly hitting the door frame 111 and causing damage to both. When the cover plate 100 is opened, the compression spring 420 releases its elastic potential energy, driving the movable rod 411 to lift the cover plate 110, which is convenient for opening and closing the cover plate 100.

[0043] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
