[0004] According to the embodiment of the utility model, the following technical scheme is adopted:

[0005] The ship hatch cover limiting device includes a cover body hinged at the opening of the ship cabin and a limiting mechanism for limiting the opening angle of the cover body, the limiting mechanism includes a mounting plate, a limiting rod hinged on the mounting plate, a supporting block slidingly connected on the limiting rod and a limiting block slidingly connected on the mounting plate, the limiting block is used to limit the deflection angle of the limiting rod, and the supporting block is used to support the deflection of the cover body, the supporting block includes a cylindrical portion sleeved and slidingly connected on the limiting rod and a supporting portion mounted on the cylindrical portion, and the supporting portion is a telescopic structure;The side surface of the cover body is provided with a slot, a plurality of through holes for aligning with the slot are formed on the limiting rod along the axial direction, and the limiting mechanism further includes a limiting pin for penetrating through the through hole and inserting into the slot.

[0007] In the scheme, a plurality of through holes are arranged on the limiting rod to align with the slot, by adjusting the angle of the limiting rod, different through holes and the slot are aligned to limit the different opening angles of the cover body, the limiting pin is inserted into the slot through the through hole to limit, the cover body and the limiting rod are triangular structure, and are limited to each other to meet the various opening angle requirements of the cover body.

[0008] Since both the cover and the limiting rod can be deflected, to facilitate the insertion of the limiting pin after aligning the through hole and slot, the limiting rod is first deflected and initially limited by the limiting block.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0021] like Figure 1 , Figure 2 As shown, the ship hatch cover limiting device includes a cover 6 hinged to the hatch opening and a limiting mechanism for limiting the opening angle of the cover 6. The limiting mechanism includes a mounting plate 1, a limiting rod 2 hinged to the mounting plate 1, a support block 10 slidably connected to the limiting rod 2, and a limiting block 3 slidably connected to the mounting plate 1. The limiting block 3 is used to limit the deflection angle of the limiting rod 2. Specifically, when the limiting rod 2 deflects, the limiting block 3 can slide to the bottom of the limiting rod 2 to support the limiting rod 2 (see...). Figure 1 As shown in the figure, this creates a limiting effect on the limiting rod 2. In the actual design process, by designing the weight of the limiting block 3 and the coefficient of friction between the limiting block 3 and the mounting plate 1, the limiting block 3 can be prevented from sliding due to the influence of the limiting rod 2 when supporting the limiting rod 2.

[0022] In the actual design process, in order to ensure that the limiting block 3 provides more stable support for the limiting rod 2, a connecting block 4 is fixed to the side of the limiting block 3. A screw 5 is threaded onto the connecting block 4. The connecting block 4 and the mounting plate 1 do not contact each other. The end of the screw 5 passes through the connecting block 4 and abuts against the mounting plate 1. By tightening the screw 5, the screw 5 abuts against the mounting plate 1, thereby increasing the frictional force of the limiting block 3 relative to the mounting plate 1 and reducing the movement of the limiting block 3.

[0023] The support block 10 is used to support the deflection of the cover 6. Specifically, the support block 10 includes a cylindrical part 8 sleeved and slidably connected to the limiting rod 2, and a support part 9 installed on the cylindrical part 8. The support part 9 is a telescopic structure. In actual design, the support part 9 can be an electric telescopic rod or a conventional telescopic rod in the prior art. A handle 11 is fixed on the cylindrical part 8, which facilitates sliding the cylindrical part 8 on the limiting rod 2.

[0024] The cover 6 has a slot on its side, and the limiting rod 2 has several through holes 15 along its axial direction for alignment with the slot. The limiting mechanism also includes a limiting pin 7 for passing through the through holes 15 and inserting into the slot. A connecting rope 12 connects the limiting pin 7 and the support block 10 to prevent the limiting pin 7 from being lost.

[0025] In practical use, first deflect the limiting rod 2, and then initially limit the limiting rod 2 through the limiting block 3. Next, deflect the cover 6 to open it. Extend the support part 9 so that it abuts against the cover 6, thus supporting the cover 6. Then slide the cylindrical part 8, causing the support block 10 to push the cover 6 to deflect and support it after deflection. At this point, the operator only needs one hand to control the deflection of the cover 6 through the support block 10, aligning the appropriate through hole 15 on the limiting rod 2 with the slot on the cover 6. With the other hand, pass the limiting pin 7 through the through hole 15 and insert it into the slot to achieve the limiting position. One person can complete the operation. When the cover 6 needs to be closed, to avoid interference with the support block 10, the support part 9 can be retracted, causing it to be offset from the cover 6.

[0026] In another embodiment of this utility model, combined with Figure 3 As shown, the support part 9 is slidably connected to the cylindrical part 8 along the outer wall of the cylindrical part 8. In actual design, a semi-circular groove can be provided on the outer wall of the cylindrical part 8, and the end of the support part 9 is slidably connected in the groove, thereby adjusting the position of the support part 9 on the cylindrical part 8.

[0027] A pressure plate 13 is detachably connected to the support part 9. The pressure plate 13 is used to press the cover 6 after it is closed onto the cabin opening. Specifically, the support part 9 has a first insertion hole, and the pressure plate 13 has a second insertion hole for aligning with the first insertion hole. It also includes a plug 14 for passing through the first insertion hole and inserting into the second insertion hole. After the cover 6 is closed, the support part 9 is slid so that the support part 9 faces upwards. Figure 3 (The direction shown is forward), then the pressure plate 13 is pressed onto the cover 6, and the cover 6 and the support part 9 are connected by the insert block 14 to limit the pressure plate 13 and prevent it from moving on the cover 6. In actual design, the weight of the pressure plate 13 can be designed to make the pressure plate 13 have a better pressing effect on the cover 6, thereby enhancing the sealing effect of the cover 6 on the ship's cabin.

[0028] In another embodiment of this utility model, combined with Figure 2 As shown, there are two sets of limiting mechanisms located on both sides of the cover 6. The two sets of limiting mechanisms support the cover 6 from both sides, making the support more stable and reducing the shaking of the cover 6.

[0029] In another embodiment of this utility model, a first scale line is provided on the limiting rod 2 along its axial direction, and a second scale line is provided on the mounting plate 1 along the sliding direction of the limiting block 3. The design of the first scale line and the second scale line makes it easy to observe the sliding distance of the support block 10 and the limiting block 3, and thus makes it easy to adjust the deflection angle of the limiting rod 2.
