Description

Technical Field

[0001] The utility model relates to the technical field of hatch covers, in particular to a hatch cover capable of replenishing oxygen. Background Technique

[0002] A ship is the general term for various vessels. A ship is a means of transportation that can sail or berth in water areas for transportation or operations. A ship is a man-made means of transportation mainly operating in geographical waters. A hatch refers to a door or grid cover that can vertically enter the cabin, that is, an opening on the ship's deck for loading and unloading goods, machine parts or personnel to enter and exit. Generally, a hatch cover is equipped, which is a device for closing the hatch on the ship.

[0003] Medical oxygen cylinders are usually placed inside the cabin. When the oxygen cylinders are consumed, they need to be replenished. When replenishing the oxygen cylinders through the hatch, the staff outside the cabin pass the oxygen cylinders to the staff inside the cabin through the hatch. In this process, the oxygen cylinders are easy to slip out of the hand and fall to the ground, and are also easy to injure the staff, with low safety. Therefore, we have developed a hatch cover capable of replenishing oxygen. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hatch cover capable of replenishing oxygen, which is convenient for replenishing oxygen cylinders. The oxygen cylinders are not easy to slip out of the hand and fall to the ground and cause damage during the replenishment process, and have high safety, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A hatch cover capable of replenishing oxygen includes a hatch and a hatch cover. One end of the hatch cover is hinged to the hatch through a hinge. A sliding rod is fixedly arranged at a position close to one side of the hinge at the lower end of the hatch. A bottom plate is fixedly arranged at the lower end of the sliding rod. A horizontal moving plate is slidably arranged on the rod wall of the sliding rod. A limiting frame is arranged inside the hatch. The lower end of the limiting frame is fixedly connected to the moving plate. A rectangular hole is formed at a position between the limiting frame and the sliding rod at the upper end of the moving plate. A rectangular plate is slidably arranged in the rectangular hole. Both the upper and lower ends of the rectangular plate extend outside the rectangular hole. A traction belt is fixedly arranged at the end of the hatch cover far from the hinge. The other end of the traction belt is fixedly connected to the upper end of the rectangular plate. Rectangular grooves are formed on both sides of the rectangular plate. Strip-shaped holes are formed on the lower side walls of the rectangular grooves. A locking mechanism is arranged in the rectangular grooves.

[0007] Preferably, the locking mechanism includes a locking block which is slidably arranged in a rectangular groove. One end of the locking block extends outside the rectangular groove, and the end of the locking block outside the rectangular groove abuts against the bottom of the moving plate. A spring is fixedly arranged at the bottom of the rectangular groove, and the other end of the spring is fixedly connected to the locking block. A push rod is fixedly arranged at the lower end of the locking block, and one end of the push rod passes through the strip-shaped hole.

[0008] Preferably, an inclined surface is formed at one end of the locking block outside the rectangular groove.

[0009] Preferably, the angle of the inclined surface is set to 45°.

[0010] Preferably, a limiting block is fixedly arranged on one side of the upper end of the bottom plate close to the limiting frame, and a limiting hole is formed on one side of the upper end of the moving plate away from the limiting frame. The limiting hole is matched with the limiting block.

[0011] Preferably, a handle is fixedly arranged on the upper end of the hatch cover.

[0012] Preferably, stoppers are fixedly arranged on both sides of the rectangular plate at the upper side of the moving plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] For the oxygen-supplementable hatch cover, by arranging a sliding rod, a limiting block, a bottom plate, a moving plate, a handle, a hatch cover, a traction belt, a hatch, a rectangular plate, a limiting frame, a locking block, a push rod, a spring, and a stopper, the oxygen cylinder is placed in the limiting frame, and then the hatch cover is closed. After the hatch cover is closed, the traction belt drives the moving plate to slowly descend. After the moving plate moves to the lower side of the sliding rod, it is convenient for the personnel inside the cabin to take down the oxygen cylinder. When the oxygen cylinder is replenished, both push rods are pushed simultaneously. While the push rods drive the locking block to squeeze the spring, the locking block moves into the rectangular groove. At this time, the rectangular plate can be taken out from the rectangular hole. Then, the moving plate rotates 180° around the sliding rod, and the limiting block is inserted into the limiting hole, so that the moving plate will not affect the normal use of the hatch, which is convenient for replenishing the oxygen cylinder. The oxygen cylinder is not easily dropped to the ground and damaged during the replenishment process, and the safety is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS
