The watertightness, strength and reliability of the hatch cover are related to the quality of cargo transportation and the safety of the ship.

[0003] In actual shipboard operations, compared with large cargo hold covers that are electrically controlled or even partially automated, small devices such as hatch covers are used more frequently. Therefore, in order to improve the convenience of using hatch covers, such small hatch covers are generally difficult to have a high-strength sealing effect. Utility Model Content

[0004] Based on the above problems existing in the prior art, an object of the embodiments of the utility model is to provide a watertight rotating rod type hatch cover, which can enhance the closing effect of the hatch cover and maintain the stability of the closing effect of the hatch cover.

[0008] The pressure assembly includes a buckle plate and a lead screw, a rotating shaft is fixed to one end of the buckle plate, a pressure plate is fixed to the end of the buckle plate away from the rotating shaft, a threaded tube is fixed to the pressure plate, the lead screw is threadedly engaged in the threaded tube, and both ends of the rotating shaft are respectively passed through a ring buckle.

[0009] Furthermore, a top plate is fixed to one side of the pinch plate close to the end cover, and when the pressure plate is rotated to be parallel to the end cover, an end of the top plate away from the pinch plate abuts against the end of the end cover.

[0010] Furthermore, a pressure plate is fixed to one end of the screw close to the rotating shaft, and a circular boss is fixed to one end of the pressure plate away from the screw. A circular groove is opened on the end cover. When the pressure plate is rotated to be parallel to the end cover, the circular boss is embedded in the circular groove.

[0011] Furthermore, a turntable is fixed to one end of the lead screw away from the pressure plate, and a plurality of gripping rods are fixed to the outer side of the turntable, and the plurality of gripping rods are arranged along the circumference of the turntable.

[0012] Furthermore, the pressurizing assembly also includes a long rod, one end of which is fixed with a sleeve, and the sleeve is sleeved on the holding rod.

[0013] Furthermore, the end cover is provided with an arched handle and an insertion rod, the arched handle is fixed on the end cover, a plurality of slots are provided on the end surface of the arched handle away from the end cover, and the ends of the insertion rod fit into the slots.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] 1. After closing the end cover on the hatch seat, the lead screw is rotated to drive the pressure plate to move in the vertical direction under the meshing action of the threaded pipe. That is, by controlling the downward displacement of the pressure plate, the pressure plate can be pressed on the end surface of the end cover. By continuously rotating the lead screw, the end cover can be continuously pressurized, so that the sealing effect between the end cover and the hatch seat is gradually strengthened;

[0016] 2. The turntable and the gripping rod can assist the user to turn the lead screw in a labor-saving manner to achieve pressurization of the end cover;

[0017] 3. By providing a circular boss, when the lead screw presses the end cover, the circular boss can be embedded in the circular groove, so that the entire pressure plate is not easy to shake when pressing the end cover, and its pressurization effect is more stable, and it can stably apply pressure to the end cover;

[0018] 4. The top plate can enhance the overall strength of the entire gusset plate and also improve the stability of the pressure plate on the end cover;

[0019] 5. Put the sleeve on the holding rod, and then push or pull the long rod to rotate the turntable, so that the lead screw drives the end cover of the pressure plate to apply pressure. In this way, it is more labor-saving to rotate the turntable;

[0020] 6. After the end cover is pressurized, the rod can be inserted into the slot closest to the long rod to prevent the long rod from reversing after the thrust or pull is removed, thereby maintaining the stability of the hatch cover after pressurization and improving its sealing performance more stably.
