In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0032] The present application discloses a ship oil cover mechanism which can realize the opening and closing of an opening on a ship bulkhead 10 for realizing oil access, and a lubricating oil tank is formed on the inside of the ship bulkhead 10, which is used for oil storage. Specifically, as shown in the drawings, Figures 1 to 4 The ship oil cover mechanism includes a refueling seat 100 and an opening and closing structure 200, the refueling seat 100 is used to be installed at the opening of the ship bulkhead 10, and the refueling seat 100 is provided with a refueling port 101 penetrating in a first direction, the first direction is shown in Figure 1 The refueling seat 100 includes a first limiting structure formed in the refueling port 101 and a first sealing surface. The two ends of the refueling port 101 in the first direction are respectively an inlet end and an outlet end, and the first limiting structure is optionally arranged close to the inlet end and extends in a second direction, the second direction is shown in Figure 1As shown in FIG. 1B, the first sealing surface is arranged close to the outlet end, and the first sealing surface can be a plane extending in the second direction. The opening and closing structure 200 includes a limiting member 210 and a blocking cover 220, and the opening and closing structure 200 is rotatably installed in the oil filler port 101 about a first straight line, and the first straight line is parallel to the second direction. Figure 1 As shown in FIG. 1C, the limiting member 210 is provided with a second limiting structure, and the blocking cover 220 is provided with a second sealing surface.

[0033] Under the driving of an external force, the opening and closing structure 200 can rotate about the first straight line and can rotate to a limiting position and an opening position. When the opening and closing structure 200 rotates to the limiting position, the second limiting structure and the first limiting structure abut and limit in the first direction, and the second sealing surface and the first sealing surface abut to seal the oil filler port 101. The second limiting structure and the first limiting structure abut and limit in the first direction, so that the opening and closing structure 200 and the oil filler seat 100 can be fixed and limited in the first direction, which is beneficial to improve the sealing between the opening and closing structure 200 and the oil filler seat 100, and avoid oil leakage of the oil filler port 101 due to poor sealing. When the opening and closing structure 200 rotates to the opening position, the second limiting structure and the first limiting structure are arranged in a staggered manner, and the second limiting structure and the first limiting structure are disengaged from the limiting. At this time, the opening and closing structure 200 is forced outward, and the opening and closing structure 200 can smoothly separate from the oil filler port 101, so that the first sealing surface and the second sealing surface are disengaged from the abutment and sealing, and the oil filler port 101 is opened, and the user can supplement oil into the lubricating oil tank inside the ship bulkhead 10 through the opened oil filler port 101.

[0034] Compared with the oil cover mechanism in the prior art which is installed at the opening of the ship bulkhead through a threaded connection fixing mode, the ship oil cover mechanism provided by the present application not only has high opening and closing efficiency of the oil filler port 101, but also is convenient and easy to use during the opening and closing process.

[0037] Continuing to refer to Figure 1 As shown in some embodiments, the limiting member 210 includes a first limiting plate 211 and a second limiting plate 212 connected in a stepped manner in the first direction, the length of the first limiting plate 211 is less than the length of the second limiting plate 212, and the limiting slot 201 is formed between the end of the first limiting plate 211 and the end of the second limiting plate 212. Specifically, the second limiting plate 212 is vertically connected to the side wall surface of the first limiting plate 211 at the upper end surface outside the first limiting plate 211 to form an L-shaped limiting slot 201.

[0038] In one embodiment, the first limiting plate 211 and the second limiting plate 212 are both rectangular plates, and in another embodiment, the first limiting plate 211 and the second limiting plate 212 are both waist-shaped plates. It should be noted that the shapes of the first limiting plate 211 and the second limiting plate 212 can be the same or different, for example, one of the first limiting plate 211 and the second limiting plate 212 is a rectangular plate, and the other is a waist-shaped plate. In addition, the first limiting plate 211 and the second limiting plate 212 can be separate pieces or integrally formed pieces.

[0039] In one embodiment, the cross section of the first hole section perpendicular to the first straight line direction is circular; in another embodiment, the cross section of the first hole section perpendicular to the first straight line direction is elliptical. It should be noted that as long as the maximum dimension of the cross section of the first hole section perpendicular to the first straight line direction is greater than the maximum length on the limiting member 210, the limiting member 210 in the open position can be separated from the first hole section.

[0040] Further, two limiting blocks 102 are oppositely arranged in the oil filler port 101, two limiting slots 201 are arranged to form two ends of the limiting member 210, and two limiting slots 201 and two limiting blocks 102 are arranged one by one.

Of course, in other embodiments, the number of limiting blocks 102 can also be more than two, and preferably an even number and oppositely arranged in pairs, as long as the gap between the adjacent two limiting blocks 102 allows the limiting member 210 to enter the oil filler port 101.

[0041] In order to enable the blocking cover 220 in the limiting position to realize sealing on the oil filling port 101 of the oil filling seat 100, in some embodiments, continuing to refer to Figure 1 As shown, the oil filling seat 100 includes a sealing protrusion 104 in the form of a ring, which is arranged in the main body structure 103 and close to the outlet end, and the inner wall surface of the sealing protrusion 104 surrounds to form a third hole section of the oil filling port 101, and the ring surface of the sealing protrusion 104 in the first direction forms a first sealing surface. The blocking cover 220 includes a sealing part 221 and a guide part 222 connected in a stepped manner in the first direction, the size of the sealing part 221 is larger than that of the guide part 222, and the ring surface of the sealing part 221 in the first direction forms a second sealing surface. In the process of inserting the opening and closing structure 200 into the oil filling seat 100, the second sealing surface gradually approaches and abuts against the first sealing surface, at this time, the sealing part 221 is located in the second hole section, and the guide part 222 is located in the third hole section. Further, a first sealing ring 700 is arranged between the first sealing surface and the second sealing surface, and in the process of the second sealing surface gradually approaching the first sealing surface, the first sealing ring 700 is deformed by being extruded, thereby improving the sealing effect. Optionally, the first sealing ring 700 is a rubber ring.

[0042] In some parallel embodiments, as shown in Figure 4 The blocking cover 220 is provided with a ring-shaped sealing groove 202 on the end surface in the first direction, and a second sealing ring 800 is arranged in the ring-shaped sealing groove 202, and the oil filling seat 100 includes a sealing protrusion 104 in the form of a ring, which can be inserted into the ring-shaped sealing groove 202 along the first direction and pressed on the second sealing ring 800. Optionally, the second sealing ring 800 is a rubber ring.

[0043] Continuing to refer to Figure 1 and Figure 3 In order to realize the relative fixation of the limiting part 210 and the blocking cover 220, in some embodiments, the ship oil cover mechanism further includes a fixing shaft 300, and the limiting part 210 and the blocking cover 220 are fixedly connected through the fixing shaft 300.

[0044] Optionally, the fixing shaft 300 includes a threaded section, and a threaded hole is arranged on the limiting part 210, and the fixing shaft 300 is threadedly connected with the limiting part 210. Further optionally, the length of the threaded section is greater than the depth of the threaded hole, so that the threaded section is partially located outside the limiting part 210.

[0045] Optionally, the fixing shaft 300 further includes an insertion section, and an insertion hole is arranged on the blocking cover 220, and the insertion section is insertedly matched with the insertion hole.

[0046] With reference back to Figures 1 to 3 As shown in some embodiments, the ship oil cover mechanism further comprises a handle 400 connected to the fixed shaft 300 and located outside the oil filler hole 101. A user can easily drive the entire opening and closing structure 200 to rotate around the first straight line by applying force to the handle 400. Optionally, the handle 400 is disc-shaped or rod-shaped.

[0047] In order to prevent the opening and closing structure 200 from being accidentally lost after being detached from the oil filler hole 101, in some embodiments, with reference back to Figures 1 to 3 As shown, the ship oil cover mechanism further comprises an anti-loss chain 500, one end of which is sleeved on the fixed shaft 300 and the other end of which is fixed on the oil filler seat 100.

[0049] The process of installing the opening and closing structure 200 of the ship oil cover mechanism into the oil filler seat 100 is as follows:

[0050] Firstly, a user rotates the opening and closing structure 200 to a position where the first limiting structure is misaligned with the second limiting structure, i.e., a position opposite to the open position and spaced apart by a distance; then, the user directly holds the handle 400 to move the opening and closing structure 200 as a whole into the oil filler hole 101 of the oil filler seat 100 until the second sealing surface of the blocking cover 220 is close to the first sealing surface of the sealing protrusion 104 and realizes the extrusion of the first sealing ring 700, or until the sealing protrusion 104 is inserted into the annular sealing groove 202 and realizes the extrusion of the second sealing ring 800, at this time, the opening and closing structure 200 is in the open position; finally, the user rotates the opening and closing structure 200 around the first straight line, so that the opening and closing structure 200 is rotated from the open position to the limiting position, at this time, the limiting groove 201 at the end of the limiting piece 210 and the limiting block 102 on the oil filler seat 100 realize limiting abutment in the first direction, and the opening and closing structure 200 cannot be detached from the oil filler seat 100.

[0051] When a user needs to perform oiling operation, the opening and closing structure 200 can be removed from the oil filler seat 100 by reversing the above steps, and after opening the oil filler hole 101, the user can perform oiling operation.
