[0003] However, traditional protruding watertight hatch covers reduce the usable deck area and waste deck space, while flush-deck welded hatch covers are difficult to open. Each time the main and auxiliary engines are unloaded, the deck must be cut and re-welded, which is very costly. Therefore, it is necessary to develop a new installation structure for flush-deck watertight hatch covers to solve this problem. Utility Model Content
[0004] In view of the above technical problems, the utility model provides an installation structure of a flush deck type watertight hatch cover, which is used to solve the problem that the flush deck welded hatch cover is difficult to open and has a high re-welding cost.
[0005] The utility model provides an installation structure of a flat deck type watertight hatch cover, comprising a deck hatch, an annular groove, a deck hatch cover, a sealing ring and a plurality of self-locking components. The annular groove is arranged along the edge of the deck hatch, the opening of the annular groove is upward, the outer annular wall of the annular groove is vertically connected to the bottom of the edge of the deck hatch, the inner annular wall of the annular groove is located at the inner circle of the deck hatch, the sealing ring is arranged in the annular groove, and the thickness of the sealing ring is less than the height of the inner annular wall of the annular groove. The deck hatch cover comprises a circle of folded edges around it. When the deck hatch cover is closed on the deck hatch, the folded edges pass through the notches of the annular groove and then cover the sealing ring. The self-locking components are evenly distributed along the edge of the deck hatch cover, and each self-locking component includes a self-locking handle, a rotating shaft sleeve, a rotating shaft and a wedge-shaped stop block. The rotating shaft sleeve is inserted and fixed on the deck hatch cover, and the rotating shaft is rotatably hung in the rotating shaft sleeve, and the top of the rotating shaft does not exceed the top of the deck hatch cover.

[0018] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.
[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0020] Please refer to Figure 1 and Figure 2 As shown, a mounting structure 100 of a flush deck type watertight hatch cover comprises a deck hatch 1, an annular groove 2, a deck hatch cover 3, a sealing ring 4 and a plurality of self-locking components 5.
[0021] The annular groove 2 is arranged along the edge of the deck hatch 1 , with the opening of the annular groove 2 facing upward. The outer annular wall of the annular groove 2 is vertically connected to the bottom of the edge of the deck hatch 1 , and the inner annular wall of the annular groove 2 is located at the inner circle of the deck hatch 1 .
[0022] The sealing ring 4 is arranged in the annular groove 2 , and the thickness of the sealing ring 4 is smaller than the height of the inner ring wall of the annular groove 2 .
[0023] The deck hatch cover 3 includes a circle of folded edges 31 around it. When the deck hatch cover 3 is closed on the deck hatch 1, the folded edges 31 pass through the notches of the annular groove 2 and cover the sealing ring 4. This ensures the watertightness of the deck hatch cover after closing.
[0024] Multiple self-locking assemblies 5 are evenly distributed along the edge of the deck hatch cover 3. Each self-locking assembly 5 includes a self-locking handle 51, a rotating shaft sleeve 52, a rotating shaft 53, and a wedge-shaped stop block 54. The rotating shaft sleeve 52 is inserted and fixed to the deck hatch cover 3. The rotating shaft 53 is rotatably mounted within the rotating shaft sleeve 52, with the top of the rotating shaft 53 not protruding from the top of the deck hatch cover 3. The self-locking handle 51 includes a locking handle 511, which is fixed to the bottom of the rotating shaft 53 and can rotate with the rotating shaft 53. The upper end of the wedge-shaped stop block 54 is fixed to the bottom of the annular groove 2, and the lower end of the wedge-shaped stop block 54 includes an inclined surface. When the locking handle 511 rotates with the rotating shaft 53, it gradually pushes the annular groove 2 upward along the inclined surface of the wedge-shaped block 54, thereby locking the sealing ring 4 and the folded edge 31 together. This ensures the watertightness of the deck hatch cover 3 to the deck hatch 1 after it is closed.
[0025] Optionally, a socket wrench 6 is further included, and a polygonal nut 531 is fixed to the top of the rotating shaft 53. The socket wrench 6 is used to be sleeved on the polygonal nut 531 and then rotate the rotating shaft 53. The socket wrench is used to facilitate rotating the rotating shaft outside the deck cabin.
[0026] Preferably, the socket wrench 6 includes a T-shaped handle 61 and a nut sleeve 62. The nut sleeve 62 opens downward and is used to be sleeved on the polygonal nut 531. The T-shaped handle 61 is fixed to the top of the nut sleeve 62 and is used to rotate the nut sleeve 62. This configuration is simple and easy to rotate.
[0027] Optionally, the height of the inner ring wall of the annular groove 2 is lower than the height of the outer ring wall of the annular groove 2. This arrangement facilitates the taking and placing of the deck hatch cover.
[0028] Optionally, the self-locking handle 51 further comprises a hand-held handle 512, which is fixedly connected to the locking handle 511. The hand-held handle is provided to facilitate opening the deck hatch cover from inside the cabin.
[0029] Preferably, the locking handle 511 and the hand-holding handle 512 are formed as an integral part, which makes the structure more solid.
[0030] Optionally, the self-locking handle 51 is fixed to the bottom of the rotating shaft 53 through a self-locking nut.
[0031] Optionally, the sealing ring 4 is made of rubber, which is economical, practical and has good water tightness.
[0032] Optionally, the outer ring wall of the annular groove 2 is vertically connected to the edge bottom of the deck hatch 1 by welding. Such a structure is firm and has good watertightness.
[0033] Optionally, the shaft sleeve 52 is welded and fixed on the deck hatch cover 3. Such a structure is convenient for the installation and fixation of the shaft sleeve and has good watertightness.
[0034] The installation structure of the flush deck type watertight hatch cover of the utility model does not affect the use area of the deck and is convenient to open and close. At the same time, the hatch cover has good watertight performance when closed and is not easy to enter with water.
[0035] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
