[0042] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0043] See also Figure 1-7 The utility model provides a technical solution: a marine rotary oil tank cover, comprising a hatch seat 1, a cover body 2, multiple groups of clamping components 3, a bent support rod 4 and a turntable 5.

[0044] A plurality of pairs of fixing plates 11 are provided on the outer wall of the hatch seat 1 , an extension platform 12 is fixed on the outer wall of the hatch seat 1 , a vertical tube 13 is fixed on the extension platform 12 , an annular boss 131 is provided on the outer side of the end of the vertical tube 13 away from the extension platform 12 , and an annular groove 1310 is opened on the annular boss 131 .

[0045] The cover body 2 is covered on the hatch seat 1, and a plurality of latch teeth 21 are provided at the edge of the outer end surface of the cover body 2. An arc-shaped through groove 2101 is opened on the latch teeth 21, and a sunken groove 2102 is opened at one end of the arc-shaped through groove 2101 of the latch teeth 21. A screw 22 is fixed at the center of the circle of the outer end surface of the cover body 2, and a plurality of vertical grooves 220 are opened on the side of the screw screw 22.

[0046] The clamping assembly 3 includes a bolt 31, a rotating shaft 32 and a nut 33. The rotating shaft 32 is rotatably connected to one end of the bolt 31, and the nut 33 is engaged with the bolt 31. Extension rods 34 are symmetrically fixed on both sides of the nut 33. The rotating shaft 32 is rotatably connected to the fixing plate 11, and the bolt 31 is stuck in the arc-shaped through groove 2101.

[0047] One end of the bent support rod 4 is inserted into the vertical tube 13, and the other end of the bent support rod 4 is fixed with a ring 1 41 and a ring 2 42. The ring 2 42 and the ring 1 41 are fixed to each other in a way that the central axis coincides. A plurality of clips 421 are provided on the inner side wall of the ring 2 42. A support frame 43 is provided on the inner side of the turning part of the bent support rod 4. One end of the support frame 43 is suspended and rotatably connected to a turntable 432. The turntable 432 abuts against the bottom wall of the annular groove 1310. A plurality of inner rods 431 are fixed on the support frame 43. The end of the inner rod 431 away from the support frame 43 is fixed to the bent support rod 4.

[0048] A plurality of connecting rods 51 are fixed on the inner side of the turntable 5, and a nut seat 52 is fixed at the connection point of the connecting rods 51. The inside of the nut seat 52 is provided with a thread, and the nut seat 52 is rotatably connected to the ring 1 41. The screw 22 passes through the ring 2 42 and the nut seat 52, and the clamping strip 421 in the ring 2 42 is embedded in the vertical groove 220 of the screw 22, and the nut seat 52 is engaged with the screw 22.

[0049] By rotating the turntable 5 , the lead screw 22 is restricted by the clamping strip 421 and meshes with the nut seat 52 . The turntable 5 can drive the lead screw 22 to move in the vertical direction through the nut seat 52 , that is, drive the cover body 2 to move up and down.

[0050] When the oil tank cover needs to be opened, the turntable 5 is rotated to move the cover body 2 upward, and then the bent support rod 4 is rotated to drive the entire cover body 2 to move to one side of the hatch seat 1, so that the cover body 2 can be quickly opened. In the process of opening the cover body 2 to one side of the hatch seat 1, there is no need to move the cover body 2. Opening the oil tank cover in this way is more labor-saving.

[0051] Moreover, when the cover body 2 is opened toward one side of the hatch seat 1, the rotating wheel 432 rotates in the annular groove 1310, and the support of the support frame 43 and the inner rod 431 assists the cover body 2 in turning and opening with less effort. Moreover, with the support of the support frame 43 and the inner rod 431, the load-bearing capacity of the bent support rod 4 is enhanced. In some embodiments, in order to ensure the sealing, the cover body 2 will be improved to have good sealing. However, after its structure is changed, its weight will generally increase. After the load-bearing capacity of the bent support rod 4 is enhanced, it can also adapt to the support requirements of the heavier cover body 2.

[0052] When the oil tank cover needs to be closed, the cover body 2 is moved downward by rotating the turntable 5 until the cover body 2 covers the hatch seat 1, and then the bolt 31 is inserted into the arc-shaped groove 2101 of the latch 21, and the nut 33 is screwed so that the nut 33 is pressed against the latch 21, so that the cover body 2 can be pressed against the hatch seat 1. Since a sunken groove 2102 is provided at the end of the arc-shaped groove 2101, the nut 33 is finally pressed into the sunken groove 2102 to prevent the nut 33 from falling off from the latch 21.

[0053] By adding an extension rod 34 to the nut 33, it is easier to turn the nut 33 without the need for tools. The nut 33 can be quickly and effortlessly twisted by simply grasping the extension rod 34, and the cover 2 can be quickly pressed against the latch teeth 21.

[0054] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
