[0005] A push rod fixing block for the linkage push rod to pass through is arranged on the inner side of the door panel.

[0006] The lock head is connected to one end of the linkage push rod through a connecting ear and is fixed by a bolt.

[0007] The linkage push rod and the ball pressure head are connected via bolt 2.

[0008] The lock head located on the outside of the door panel is connected to one end of the lock tongue, and the other end of the lock tongue is locked or released with the decorative panel.

[0009] An embedded frame is provided at the connection between the door panel and the decorative panel.

[0010] Compared with the prior art, the utility model has a neat and beautiful appearance, the hinge is hidden in the plate, the outer surface is not abrupt, the opening method is one lock with multiple linkages, one lock head is provided with multiple clamping points, it only needs to be opened once, and the multiple clamping points can evenly clamp the door frame and the door panel, effectively preventing noise when the ship vibrates.

[0019] The utility model is further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 8 As shown, an inlet and outlet 7 is provided on one side of the decorative panel 1, a door panel 2 is provided in the inlet and outlet 7, a mounting hole is provided at the connection between the door panel 2 and the decorative panel 1, a hinge 3 is provided in the mounting hole, one end of the door panel 2 is connected to the decorative panel 1 through the hinge 3, and a lock 4 is provided at the other end of the door panel 2. The left and right sides of the lock 4 located on the inner side of the door panel 2 are respectively connected to one end of a linkage push rod 5, the other end of the linkage push rod 5 is connected to one end of a ball pressure head 6, and the other end of the ball pressure head 6 is pressed on the decorative panels 1 on both sides of the inlet and outlet 7.

[0021] A push rod fixing block 8 for the linkage push rod 5 to pass through is provided on the inner side of the door panel 2. The push rod fixing block 8 is fixed on the inner side of the door panel to prevent the elastic shaking of the linkage push rod 5 so that the force can only act in one direction.

[0022] The lock head 4 is connected to one end of the linkage push rod 5 through a connecting ear 9 and fixed by a bolt 10. The linkage push rod 5 and the ball pressure head 6 are connected by a bolt 2 11.

[0023] The lock head 4 located on the outer side of the door panel 2 is connected to one end of the lock tongue 12 , and the other end of the lock tongue 12 is locked or released with the decorative panel 1 .

[0024] An embedded frame 13 is provided at the connection between the door panel 2 and the decorative panel 1 .

[0025] In the utility model, the hinge 3 is arranged in the installation hole, hidden in the embedded frame 13 between the door panel 2 and the decorative panel 1, and the sight outside the door is only a whole door panel and a lock hole, without other protrusions. The aesthetics is greatly improved, and when the door panel 2 is opened, the hinge flips inward along the center of the hinge, and there will be no interference with other objects.

[0026] When the door panel 2 needs to be opened, the lock head 4 is turned to drive the linkage push rod 5 to act on the ball pressure head 6, and the ball pressure head 6 and the decorative panel 1 will be pressed tighter and tighter, and the lock tongue 12 will also be linked to press the decorative panel 1. The above multiple pressing points reduce the overall shaking of the door panel 2. When the ship is sailing, it will not be affected by the vibration of the ship's main engine or other machines to make noise, greatly improving the quiet performance of the inspection door.

[0027] When installing Figure 8 As shown, first determine the required size of the inspection door, use a jigsaw to open an inlet and outlet 7 of corresponding size on the decorative panel 1, then insert the embedded frame 13 into the decorative panel 1 with the opening, and finally install the door panel 2 to check its closure. When used specifically, the opening size can also be designed in advance, and the decorative panel manufacturer can install it when it is supplied in the factory, which greatly improves the internal outfitting integrity when the ship is assembled in sections.

[0028] The utility model is easy to manufacture and install, has outstanding silent performance and quick opening function, and has the advantage of beautiful appearance. The size of the inlet and outlet can be freely selected according to the design needs, which can meet the use scenarios of most ship maintenance doors.
