A hand held hatch cover structure and its opening and closing method

Abstract

The invention provides a hand supporting hatch cover structure and an opening and closing method thereof, and belongs to the ship equipment field. The hand supporting hatch cover structure and the opening and closing method thereof solve the problems that sailors cannot conveniently enter and exit out of a hatch cover structure, and a hand supporting mechanism additionally arranged occupies spacein a cabin. The hand supporting hatch cover structure comprises an inner cabin and a cabin barrel, wherein a hatch cover is hinged at the top end of the cabin barrel through a hinged piece. The hand supporting hatch cover structure further comprises a handrail mechanism, wherein the handrail mechanism comprises a pull hand rod and two arc handrail rods, two handrail holes are formed in the cabin barrel, the two handrail rods are arranged in the two handrail holes in a penetration mode, each handrail rod comprises a fixing rod and a moving rod, the length of each fixing rod is as same as that of each handrail hole, the top ends of the two fixing rods are fixed on the inner side face of the hatch cover, the bottom ends of the two fixing rods are hinged with the top ends of the moving rods through spherical hinges, two ends of each handrail rod are hinged with the bottom end of the each moving rod through hinged pieces II, a clamp seat is fixed on the inner wall of the inner cabin, and aclamp groove is formed in the clamp seat. The hand supporting hatch cover structure optimizes a folding structure, can further reduce the size of space in the cabin, and facilitates entering and exiting of the sailors.

Description

technical field [0001] The invention belongs to the technical field of ship equipment, and relates to a hand-held hatch cover structure and an opening and closing method thereof. Background technique [0002] The hatch cover includes the tank tube whose bottom end is fixed on the inner cabin. The top of the tank tube is usually hinged to the hatch cover through hinges. The hatch cover has the function of waterproofing and sealing. After the traditional hatch cover is opened, it does not have a hand-held mechanism. Inconvenient to get in and out. [0003] The existing application number is 201910233409.0, which is a Chinese invention patent titled "A hatch cover with an adjustable hand-held mechanism and its use method", which provides a hatch cover that is convenient for sailors to enter and exit, which is hinged at the bottom of the cover plate The hand-held mechanism, by unfolding or folding the hand-held mechanism, uses the hand-held mechanism to enter and exit the hatch...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the handrail mechanism has a curved handrail tube, the bottom end of the folded handrail tube will inevitably touch the inner wall of the inner cabin, so the middle part of the handrail tube will protrude and affect the space in the cabin. In order to reduce the occupied space in the cabin, the length of the handrail tube It needs to be shortened, and the handrail tube that is too short is not convenient to use;

[0005] 2. And the length of the handrail tube directly determines the opening angle of the cover plate, so the too short handrail tube will also reduce the opening angle of the cover plate, which will affect the entry and exit of sailors;

[0006] 3. After the hand-held mechanism is folded, it still cannot be attached to the inner cabin, and it will still take up a lot of space in the cabin
