[0022] The following further describes the present application in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and are not intended to limit the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0023] Please refer to the attached Figure 1-2, an embodiment of the present application provides a cargo door structure for opening and closing a cargo hold. The cargo door structure includes a door body 100, a hold door lock, a stopper, and a lock. The hold door lock is disposed on the door body 100. The hold door lock includes a lock body, a first rotating handle 200, and a second rotating handle 300. Both the first rotating handle 200 and the second rotating handle 300 are installed on the lock body and are respectively located on the inner and outer sides of the door body 100. Among them, the first rotating handle 200 is located on the outer side of the door body 100 for a crew member outside the cargo hold to operate the hold door lock, and the second rotating handle 300 is located on the inner side of the door body 100 for a crew member inside the cargo hold to operate the hold door lock. The first rotating handle 200 has a locked position and an unlocked position in its rotation direction. The rotation direction of the first rotating handle 200 from the locked position to the unlocked position by rotating upward is the unlocking direction, and the rotation direction of the first rotating handle 200 from the unlocked position to the locked position by rotating downward is the locking direction. The unlocking direction can be the counterclockwise direction, and the locking direction can be the clockwise direction. When in the locked position, the first rotating handle 200 can, but is not limited to, be in a vertical state or close to a vertical state. When in the unlocked position, the first rotating handle 200 can, but is not limited to, be in a horizontal state or close to a horizontal state. The stopper is disposed on the outer side of the door body 100. The stopper is located on the downstream side of the locked position along the locking direction of the first rotating handle 200, that is, the locked position and the stopper are arranged along the locking direction of the first rotating handle 200. The stopper is disposed close to the locked position so that the stopper can perform a stopping fit on the first rotating handle 200 to limit the first rotating handle 200 from continuing to rotate along the locking direction. When the first rotating handle 200 rotates to the locked position, the lock can lock between the first rotating handle 200 and the stopper. The first rotating handle 200 is restricted from rotating along the unlocking direction under the locking of the lock, thereby avoiding the situation that the first rotating handle 200 rotates along the unlocking direction due to misoperation.

[0024] In this embodiment, the stopper can limit the rotation of the first rotating handle 200 in the locking direction, avoiding the situation that the handle rotates downward excessively when the crew locks the cargo door, improving the protection effect on the hold door lock, extending the service life of the hold door lock. At the same time, the presence of the stopper can also play a role in prompting the unlocking rotation direction of the first rotating handle 200. In addition, the first rotating handle 200 in the locked position and the stopper can be locked by a lock, so that the first rotating handle 200 will not be in an unlocked state due to misoperation by the crew, avoiding the collision noise between the door and the cabin during the operation of the ship and the situation that the goods slide out of the cabin, reducing the safety hazards of the ship.

[0025] Among them, the smaller the distance between the stopper and the locked position, the better. This distance can be, but is not limited to, within 2 cm.

[0026] The stopper may be, but is not limited to, a stopper plate 110 or a stopper block. Preferably, the stopper plate 110 is a stopper plate 110 .

[0027] The first rotating handle 200 and the second rotating handle 300 may be, but are not limited to, rod-shaped structures. Preferably, the first rotating handle 200 and the second rotating handle 300 may be round rod structures.

[0028] The door body 100 may be, but is not limited to, a wire mesh door type door body 100 or the like.

[0029] The stopper and the door body 100 can be fixedly arranged, for example, welded therebetween. Of course, in other embodiments, the stopper can be telescopically arranged to adjust the protruding distance of the stopper relative to the door body 100. Specifically, the door body 100 is provided with a mounting groove, and the stopper is movably inserted in the mounting groove. The user can pull the stopper out of the mounting groove to the stop position and push the stopper back into the mounting groove to the avoidance position. The stopper at the stop position can stop the first rotating handle 200, and the stopper at the avoidance position is partially exposed from the mounting groove to facilitate the user to drive the stopper. The outer surface of the stopper is provided with a limiting protrusion, the groove wall of the mounting groove is provided with a guide groove, and there is a spacing between the guide groove and the groove opening of the mounting groove, and the limiting protrusion is slidably arranged in the guide groove. When in the stop position, the limiting protrusion abuts against the groove wall of the guide groove to prevent the stopper from detaching from the groove opening of the mounting groove.

[0030] In some embodiments of the present application, the first rotary handle 200 includes a mounting section 210, a gripping section 220, and a stopper matching section 230 connected in sequence, the mounting section 210 is mounted in the lock body of the hatch lock, and the stopper matching section 230 is used to match with the stopper, wherein the stopper matching section 230 is located on the side of the gripping section 220 close to the door body 100. Through the above arrangement, the portion for the user to grip on the first rotary handle 200 and the stopper matching portion matching with the stopper can be staggered, so as to prevent the crew from accidentally touching the stopper when operating the first rotary handle 200, thereby improving the operational safety of the cargo door.

[0031] In some embodiments of the present application, the lock is a padlock 400, the stop member is provided with a first through hole, the stop mating section 230 is provided with a second through hole 231, the first through hole and the second through hole 231 are for the lock beam of the padlock 400 to pass through, and after passing through the first through hole and the second through hole 231, the lock beam is locked into the locking upper lock hole, thereby completing the locking between the first rotating handle 200 and the stop member.

[0032] In order to facilitate the opening of the second through hole 231 , the end of the stop fitting section 230 close to the door body 100 may be set as a disc structure, and the second through hole 231 is opened in the middle of the disc structure.

[0033] Among them, the holding section 220 is vertically arranged, which is not only convenient for the user to hold, but also enables the first rotating handle 200 to have a relatively small unfolded volume, reducing potential safety hazards. Of course, in other embodiments, the holding section 220 can also be arranged obliquely relative to the vertical direction, etc.

[0034] Among them, both the connection between the holding section 220 and the installation section 210 and the connection between the holding section 220 and the stop cooperation section 230 are arc-transition connections, so that the first rotating handle 200 has no right-angle structure, increasing the safety of the first rotating handle 200.

[0035] The present application also provides a ship, which has a cargo hold, and the cargo hold is configured with the above-mentioned cargo hold door structure.

[0036] It should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. in the above text is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model.
