Abstract
Description
Technical Field
[0001] This application relates to the field of ship hatch technology, and more particularly to a hatch. Background Technology
[0002] Ships include passenger ships, cargo ships, engineering vessels, etc., and their hatches serve to prevent wind and water from entering the cabin.
[0003] In related technologies, hatches can be opened or closed from inside the ship's cabin or from outside the ship's cabin, i.e., from the deck.
[0004] Therefore, the relevant technologies suffer from poor anti-theft performance of the hatches. Utility Model Content
[0005] This application provides a hatch designed to solve the technical problem of poor anti-theft performance of hatches, thereby improving the anti-theft performance of hatches.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] This application provides a hatch, suitable for ships, comprising:
[0008] Door frames provide passageway space;
[0009] A door leaf is disposed within the passage space and is movably connected to the door frame. The door leaf is configured to open or close the passage space. The side of the door leaf facing the interior of the ship's cabin has a first handle, which is rotatably connected to the door leaf.
[0010] A locking device is movably disposed on the side of the door leaf facing away from the outside of the ship cabin. The locking device is connected to a first handle. The locking device has a locking part. When the first handle rotates relative to the door leaf, the first handle drives the locking device to move, so that the locking part locks or unlocks the door frame.
[0011] A limiting member is fixedly installed on the side of the door facing the interior of the ship's cabin. When the locking part is locked to the door frame, the limiting member is connected to the first handle so that the first handle is fixed relative to the door.
[0012] In some embodiments, the first handle has a limiting structure, and when the locking part and the door frame are in the locked state, the limiting member is connected to the limiting structure.
[0013] In some embodiments, the limiting structure is a limiting hole, and the limiting member is a limiting pin. When the locking part and the door frame are in the locked state, the limiting pin is inserted into the limiting hole.
[0014] In some embodiments, the peripheral wall of the limiting pin has one of a limiting protrusion and a limiting groove, and the wall of the limiting hole has the other of the limiting protrusion and the limiting groove. When the limiting pin is inserted into the limiting hole, the limiting protrusion and the limiting groove cooperate.
[0015] In some embodiments, the limiting member further includes a connecting portion, the length of which is adjustable, so that the limiting member can adapt to different positions of the limiting structure relative to the door leaf.
[0016] In some embodiments, the locking part has a first electromagnetic component, and the door frame has a second electromagnetic component at a corresponding position. When the locking part and the door frame are in the locked state, the first electromagnetic component and the second electromagnetic component are magnetically attracted.
[0017] In some embodiments, the hatch further includes a threshold, which is disposed on the side of the passage space near the ground, is movably connected to the door frame, and is sealed to the door leaf. The threshold can be opened or closed relative to the passage space.
[0018] In some embodiments, the threshold has a stop structure on the side facing the interior of the ship's cabin, and a stop portion is provided on the deck outside the ship's cabin. When the threshold is in a closed state relative to the passage space, the stop structure abuts against the door frame. When the threshold is in an open state relative to the passage space, the stop structure abuts against the stop portion.
[0019] In some embodiments, the door leaf has a first locking structure, and when the locking part and the door frame are in the locked state, the door leaf is locked to the door frame by the first locking structure; and / or,
[0020] The threshold has a second locking structure, which locks the threshold to the door frame when the threshold is closed relative to the passage space.
[0021] In some embodiments, at least one of the following is included:
[0022] The connecting part is at least one of a chain, rope, flexible tube, and telescopic spring;
[0023] The stopping structure is at least one of columnar structure, block structure, and plate structure;
[0024] The stop portion is at least one of a groove or a protrusion.
[0025] The hatch provided in this application includes a door frame, a door leaf, a locking device, and a limiting member. The door frame has a passage space; the door leaf is disposed within the passage space and is movably connected to the door frame. The door leaf is configured to open or close the passage space. A first handle is provided on the side of the door leaf facing the interior of the ship's cabin, and the first handle is rotatably connected to the door leaf. The locking device is movably disposed on the side of the door leaf facing away from the exterior of the ship's cabin. The locking device is connected to the first handle and has a locking part. When the first handle rotates relative to the door leaf, the first handle drives the locking device to move, so that the locking part locks or unlocks the door frame, thereby locking or unlocking the door leaf and the door frame. The limiting member is fixedly disposed on the side of the door leaf facing the interior of the ship's cabin. When the locking part and the door frame are in a locked state, the limiting member is connected to the first handle, so that the first handle is in a fixed state relative to the door leaf. In this application, after the first handle rotates relative to the door leaf, locking the locking part of the locking device against the door frame, i.e., after the door leaf is locked relative to the door frame, a limiting member set on the door leaf is connected to the first handle to fix the first handle relative to the door leaf, restricting the movement of the first handle. During the continuous connection between the limiting member and the first handle, the locking part of the locking device can remain locked to the door frame. Only by releasing the connection between the limiting member and the first handle can the lock between the locking part and the door frame be released, allowing the door leaf to be opened relative to the door frame. The limiting member is set on the side of the door leaf facing the interior of the ship's cabin. Therefore, when the limiting member is connected to the first handle, the connection between the limiting member and the first handle can only be released from inside the ship's cabin, allowing the locking part to be unlocked from the door frame. It is impossible to release the connection between the limiting member and the first handle from outside the ship's cabin, preventing personnel outside the ship's cabin from entering the cabin, thus achieving the function of theft prevention and improving the anti-theft performance of the cabin door.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0047] The hatches on a ship serve to protect against wind and water, preventing seawater, rainwater, and wind from entering the cabin. The types of ships include, but are not limited to, passenger ships, cargo ships, and engineering vessels used at sea.
[0048] This application provides a ship hatch. In some embodiments, the hatch can be opened or closed from inside the ship's cabin or from outside the cabin, i.e., on the deck. Therefore, anyone can open the hatch from the outside and enter the ship's cabin. As a result, the ship hatch has the technical problem of poor anti-theft performance.
[0049] In addition, the hatch has a threshold. According to the 1966 International Load Line Convention, the load line determination rules are as follows: Position 1 is on open freeboard decks and aft riser decks, and on open superstructure decks up to one-quarter of the ship's length from the forward perpendicular; Position 2 is on open superstructure decks after one-quarter of the ship's length from the forward perpendicular. In Position 1, the threshold should be at least 600mm above the deck; in Position 2, it should be at least 380mm above the deck. Because the threshold has a certain height and is fixed relative to the hatch, it cannot be moved, thus hindering the passage of pedestrians and cargo. Therefore, this ship's hatch also presents a technical problem of poor passageability.
[0050] To address the aforementioned issues, this application presents a hatch design suitable for ships.
[0051] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.
[0052] Figure 1 A schematic diagram of a door in a locked state, provided as an embodiment of this application, from the perspective of the ship's cabin towards the deck; Figure 2 This is a structural schematic diagram of a hatch provided in an embodiment of this application from another perspective. (See attached diagram.) Figure 1 and Figure 2 As shown, the hatch 10 includes a door frame 100, a door leaf 200, a locking device 300, and a limiting member 400.
[0053] The door frame 100 has a passage space; the door leaf 200 is disposed in the passage space and is movably connected to the door frame 100. The door leaf 200 is configured to open or close the passage space. The side of the door leaf 200 facing the interior of the ship cabin 610 has a first handle 210, which is rotatably connected to the door leaf 200; the locking device 300 is movably disposed on the side of the door leaf 200 away from the exterior of the ship cabin. The locking device 300 is connected to the first handle 210 and has a locking part 310. When the first handle 210 rotates relative to the door leaf 200, the first handle 210 drives the locking device 300 to move, so that the locking part 310 locks or unlocks the door frame 100, thereby fixing or unlocking the door leaf 200 relative to the door frame 100.
[0054] The limiting member 400 is fixedly installed on the side of the door leaf 200 facing the interior of the ship's cabin 610. When the locking part 310 is locked to the door frame 100, the limiting member 400 is connected to the first handle 210, so that the first handle 210 is fixed relative to the door leaf 200. Since the first handle 210 is connected to the locking device 300, when the first handle 210 is fixed to the door leaf 200 by the limiting member 400, the state of the locking device 300 is also fixed. That is, during the period when the first handle 210 is fixed relative to the door leaf 200, the locking part 310 of the locking device 300 remains locked to the door frame 100. At this time, the door leaf 200 cannot be opened relative to the door frame 100. And because the limiting member 400 is installed on the door leaf 200... The door 200 faces the side of the ship's cabin 610. Therefore, only personnel inside the ship's cabin 610 can release the connection between the limiting member 400 and the first handle 210, so that the locking part 310 of the locking device 300 is unlocked from the door frame 100, and the door 200 can be opened relative to the door frame 100. Personnel outside the cabin, that is, personnel on the deck 600, lock the door between the locking part 310 and the door frame 100. When the limiting member 400 is connected to the first handle 210, the door 200 cannot be opened to enter the ship's cabin 610. Therefore, the addition of the limiting member 400 prevents external personnel from entering the ship's cabin 610 at will, thereby improving the anti-theft performance of the cabin door 10.
[0055] It should be noted that the opening direction of the door 200 is only towards the outside of the ship's cabin, that is, the hatch 10 provided in this application embodiment is an outward-opening door.
[0056] In some embodiments, the number of door panels 200 can be one, two, etc., for example, such as Figure 1As shown, there are two door leaves 200 along the horizontal direction. The two door leaves 200 are symmetrically arranged about the center line of the door frame 100. The two opposite sides of the two door leaves 200 are movably connected to the door frame 100. Thus, opening either one of the two door leaves 200 or both of them can open part of the passage space to allow people or goods to pass through. However, only when both door leaves 200 are closed can the passage space corresponding to the door leaf 200 be closed. In this embodiment of the application, the example of setting two door leaves 200 in the door frame 100 is used for explanation. Opening only one door leaf 200 has the same beneficial effect as opening both door leaves 200, and will not be elaborated here.
[0057] It should be noted that the number of locking devices 300, the number of first handles 210, and the number of limiting members 400 are consistent with the number of door leaves 200 provided in the door frame 100. Each door leaf 200 corresponds to one locking device 300, one first handle 210, and one limiting member 400. Specifically, the first handle 210 corresponding to one door leaf 200 is connected to the locking device 300. For example, if two door leaves 200 are provided in the door frame 100, then they correspond to two locking devices 300, two first handles 210, and two limiting members 400, respectively. When the operator is inside the ship's cabin 610 and both door leaves 200 are configured to be open, the operator needs to turn the two handles relative to the door leaves 200. The movement of the door 200 causes the corresponding locking device 300 to move, thereby releasing the locking part 310 of the corresponding locking device 300 from the door frame 100. This allows the two doors 200 to open the passageway by pushing the corresponding first handle 210, enabling people or goods to enter or exit the cabin. Similarly, when the operator is inside the cabin 610 and the two doors 200 are configured to be closed, the operator first pulls the two doors 200 to the passageway position of the door frame 100, and then rotates the two first handles 210 to move the corresponding locking device 300, locking the locking part 310 of the corresponding locking device 300 from the door frame 100, thereby closing the passageway and preventing people or goods from entering or exiting the cabin.
[0058] Furthermore, when the passage space is opened or closed by the two doors 200, the corresponding limiting members 400 fixedly installed on each door 200 are connected to the corresponding first handles 210, so that the two first handles 210 are fixedly connected to the corresponding doors 200, thereby locking the locking parts 310 of the two locking devices 300 connected to the two first handles 210 to the door frame 100, thus completing the locking of the doors 200. Since the two limiting members 400 corresponding to the two doors 200 are both set on the side of the doors 200 facing the interior of the ship's cabin 610, personnel outside the ship's cabin, i.e., on the deck 600, cannot open the cabin door 10, thereby improving the anti-theft performance of the cabin door 10.
[0059] In other embodiments, the door 200 consists of two door panels and side panels disposed at the edges of the two door panels for connecting the two door panels. The two door panels and the side panels together enclose an accommodating space. The first handle 210 and the limiting member 400 are both disposed on the side of the door panel facing the ship's cabin 610, which is closer to the cabin interior 610. The locking device 300 is disposed in the accommodating space and is not limited to being movably connected to either of the two door panels. This method conceals the locking device 300, making the hatch 10 more aesthetically pleasing while increasing the protection of the locking device 300. In some embodiments, see further. Figure 1 The first handle 210 includes a grip portion 211 and a locking portion 212. The grip portion 211 is a bent rod shape. One end of the grip portion 211 is rotatably connected to the door leaf 200. One end of the locking portion 212 is fixedly connected to the end of the grip portion 211. The extension direction of the locking portion 212 forms an angle with the grip portion 211. The angle range is 120° to 150°. For example, the angle between the two is 120°, 135°, 150°, etc.
[0060] The locking device 300 also includes a plurality of first links 320 and an equal number of second links 330. The first links 320 and second links 330 are connected sequentially to form a linkage system. For example, a locking device 300 includes four first links 320 and four second links 330, which are connected sequentially in a movable connection that allows relative rotation. The second links 330 are T-shaped with three ends, the two ends of which are respectively connected to the corresponding links on the same horizontal line. The two adjacent first links 320 are connected, and the third end of the second link 330 is rotatably connected to the door leaf 200, so that the linkage system can rotate relative to the door leaf 200. The end of the interlocking part 212 away from the grip part 211 is rotatably connected to one of the first links 320 in the linkage system, so that when the operator applies external force to the grip part 211 of the first handle 210, the interlocking part 212 is rotated, thereby causing the linkage system to rotate around the third end of the second link 330, and then causing the locking part 310 to rotate relative to the door leaf 200.
[0061] Additionally, for example, such as Figure 1As shown, the locking part 310 of the locking device 300 consists of multiple latch structures. The latches include, but are not limited to, plate-shaped pieces, shaft-shaped pieces, or plate-shaped pieces with corners. They are connected to the door leaf 200 via a pivot and can rotate relative to the door leaf 200. The pivot is located at a corner. One end of the latch has a groove, and the first connecting rod 320 has a slider. The groove and the slider are matched. Multiple latch structures are respectively located between the door leaf 200 and the door frame 100, between two door leaves 200, and between the door leaf 200 and the threshold 500. Corresponding positions on the door frame 100, threshold 500, and door leaf 200 can be provided with grooves, allowing the end of the latch away from the connecting rod to engage with the groove, thereby locking the door leaf 200 to the door frame 100.
[0062] The above embodiments are implemented as follows: Figure 1 As shown, along the horizontal direction, taking the left door 200 as an example, when the operator is inside the ship's cabin 610, and the door 200 is in the locked state ( Figure 1 (As shown in the diagram), firstly, rotate the first handle 210 clockwise by 90°, causing the gripping part 211 of the first handle 210 to extend vertically. The entire linkage system rotates clockwise relative to the door leaf 200 around the third end of all the second links 330 in the linkage system. This causes the sliders on each first link 320 in the linkage system to rotate clockwise, and the sliding grooves on each latch slide relative to the sliders on the first link 320, causing each latch to rotate counterclockwise relative to the door leaf 200 around its corresponding pivot. This causes the end of the latch away from the first link 320 to retract from the corresponding groove on the door frame 100 and the threshold 500, thus completing the unlocking step between the locking device 300 and the door frame 100. Similarly, the unlocking principle between the right door leaf 200 or the locking device 300 on the right door leaf 200 and the door frame 100 is the same as that of the left door leaf 200. However, the difference is that the right door leaf 200 corresponds to the first handle... 210. The rotation direction of the linkage system and the locking part 310 is opposite to that of the left door leaf 200. When the right door leaf 200 needs to be unlocked from the door frame 100, the corresponding first handle 210 needs to be rotated 90° counterclockwise, so that the grip part 211 of the corresponding first handle 210 extends in the vertical direction, thereby driving the corresponding linkage system to rotate counterclockwise relative to the door leaf 200 around the third end of all the second links 330 in the linkage system. The corresponding locking part 310 rotates clockwise and withdraws from the grooves on the corresponding door frame 100, threshold 500, and left door leaf 200, thereby completing the unlocking of the right door leaf 200 relative to the door frame 100. When both doors 200 need to be opened, the two doors 200 on the left and right sides can be opened in accordance with the above steps. After completion, push the corresponding first handle 210 towards the outside of the ship's cabin to open the door leaf 200 and expose the passage space, so as to facilitate the entry and exit of people or goods into the ship's cabin 610.
[0063] When it is necessary to close the opened door 200 and lock it to the door frame 100, the method is as follows: Taking the left door 200 as an example, in the horizontal direction, with the operator inside the ship's cabin 610, first pull the first handle 210 corresponding to the left door 200 towards the ship's cabin 610, pulling both doors 200 into the passageway. Then, rotate the first handle 210, which extends vertically along the grip portion 211 on the left door 200, counterclockwise by 90°. Figure 1 At the designated position, the corresponding linkage system rotates counterclockwise relative to the door leaf 200 around the third end of all the second links 330 in the linkage system, and the corresponding locking part 310 rotates clockwise to insert into the groove on the corresponding door frame 100 and threshold 500, thereby completing the locking of the left door leaf 200 relative to the door frame 100; similarly, the first handle 210 extending vertically from the grip part 211 on the right door leaf 200 is rotated 90° clockwise to... Figure 1 At the designated position, the corresponding linkage system rotates clockwise relative to the door leaf 200 around the third end of all the second linkages 330 in the linkage system. The corresponding locking part 310 rotates clockwise and inserts into the groove on the corresponding door frame 100, threshold 500, and left door leaf 200, thereby locking the right door leaf 200 relative to the door frame 100. After locking both door leaves 200 relative to the door frame 100, the corresponding limiting part 400 on each door leaf 200 is connected to the corresponding first handle 210, thereby fixing the corresponding first handle 210 relative to the corresponding door leaf 200. Then, the corresponding linkage system and the locking part 310 are fixed relative to the door leaf 200, thereby completing the locking and limiting of both door leaves 200 relative to the door frame 100. Moreover, personnel outside the ship's cabin, i.e., on the deck 600, cannot open the hatch 10, thus improving the anti-theft performance of the hatch 10.
[0064] In the above embodiments, the movable connection between the door leaf 200 and the door frame 100 can be a hinge connection; the rotatable connection between the first handle 210 and the door leaf 200, between the interlocking part 212 and the first connecting rod 320, between the first connecting rod 320 and the second connecting rod 330, between the second connecting rod 330 and the door leaf 200, and between the locking part 310 and the door leaf 200 can all be a pivot connection; the fixed connection between the gripping part 211 and the interlocking part 212 includes, but is not limited to, bolt and nut connection, snap connection, pin connection, bonding, welding, etc.
[0065] Additionally, in some embodiments, such as Figure 3 and Figure 4As shown, each door panel 200 has a second handle 220 on the side facing outwards from the ship's cabin. This second handle 220 only has a grip portion 211. The shape of the second handle 220 is identical to that of the first handle 210; both are plate-like, shaft-like, or plate-like components with corners. One end of the second handle 220 passes through the door panel 200 and is fixedly connected to that end of the first handle 210. This allows personnel outside the ship's cabin to access the second handle 220 even without connecting the limiting member 400 to the first handle 210. The rotation of the door leaf 200 allows the door frame 100 to open or close, thereby increasing the flexibility of opening and closing the door leaf 200. It should be noted that when the limiting member 400 is connected to the first handle 210, the operator cannot rotate it through the second handle 220. The setting of the second handle 220 does not affect the anti-theft performance of the hatch 10. The fixed connection between the second handle 220 and the first handle 210 includes, but is not limited to, bolt and nut connection, snap connection, pin connection, bonding, welding, etc.
[0066] Specifically, the first handle 210 has a limiting structure. When the locking part 310 is locked to the door frame 100, the limiting member 400 is connected to the limiting structure so that the first handle 210 is fixed relative to the door leaf 200 through the connection between the limiting structure and the limiting member 400.
[0067] Combination Figure 1 and Figure 4 As shown, the limiting structure is provided on the interlocking part 212 of the first handle 210. For example, the locking structure is the limiting hole 213, and the limiting member 400 is the limiting pin 420. When the locking part 310 and the door frame 100 are in the locked state, the limiting pin 420 is inserted into the limiting hole 213.
[0068] Of course, when the locking part 310 and the door frame 100 are in the locked and open states, the limiting hole 213 on the interlocking part 212 of the first handle 210 is provided with a groove at the position corresponding to the door leaf 200, so that when the limiting member 400 is the limiting pin 420, it can be inserted into the limiting hole 213 and the limiting groove 214, thereby fixing the first handle 210 relative to the door leaf 200, and also fixing the linkage system and the locking part 310 relative to the door leaf 200. The setting of the limiting structure and the limiting member 400, on the one hand, makes the door leaf 200... When in a stable open or closed state, the first handle 210, linkage system, and locking part 310 are all stable and controllable and will not rotate on their own. On the other hand, when the door leaf 200 is locked relative to the door frame 100, personnel outside the ship's cabin, i.e., on the deck 600, cannot open the hatch 10, thus improving the anti-theft performance of the hatch 10. Furthermore, the setting of the limiting structure as the limiting hole 213 and the limiting member 400 as the limiting pin 420 makes the structure of the first handle 210 and the limiting member 400 plugged and fixed together simple, easy to implement, and low in cost.
[0069] Additionally, in some embodiments, such as Figure 5 As shown, the peripheral wall of the limiting pin 420 has one of a limiting protrusion 421 and a limiting groove 214, and the wall of the limiting hole 213 has the other of a limiting protrusion 421 and a limiting groove 214. When the limiting pin 420 is inserted into the limiting hole 213, the limiting protrusion 421 and the limiting groove 214 cooperate, so that when the limiting pin 420 and the limiting hole 213 are connected, they are engaged by the limiting protrusion 421 and the limiting structure, thereby enhancing the connection strength between the limiting member 400 and the limiting structure, and preventing the limiting member 400 from falling off due to the swaying of the hull when it is connected to the first handle 210.
[0070] For example, such as Figure 5 As shown, when the limiting pin 420 is inserted into the limiting hole, a limiting protrusion 421 is provided on the peripheral wall of the limiting pin 420 near the door leaf 200 along the extension direction of the limiting pin 420. A limiting groove 214 is provided on the hole wall of the limiting hole 213 near the door leaf 200 in the thickness direction of the limiting hole 213. This allows the limiting pin 420 to engage with the limiting hole 213 when the limiting member 400 is connected to the first handle 210, thereby enhancing the connection strength between the limiting pin 420 and the limiting hole 213 and preventing the limiting pin 420 from accidentally falling out of the limiting hole 213.
[0071] Furthermore, in some embodiments, the return Figure 1As shown, the limiting member 400 also includes a connecting part 410, the length of which is adjustable to adapt the limiting member 400 to different positions of the limiting structure relative to the door leaf 200. To reiterate, when the locking part 310 of the locking device 300 is locked or unlocked with the door frame 100, because the first handle 210 is connected to the locking device 300, the locking or unlocking between the locking device 300 and the door frame 100 is achieved by the rotation of the first handle 210, which applies a force to the locking device 300. This causes the locking part 310 of the locking device 300 to engage or disengage with the corresponding groove on the door frame 100, adjacent door leaf 200, or threshold 500. Therefore, when the locking part 310 is in a locked or unlocked state with the door frame 100, the first handle 210 relative to the door frame 100... The positions on the door frame 100 are different, but in order to improve the anti-theft performance of the hatch 10 when the locking part 310 is locked to the door frame 100, the limiting member 400 needs to be fixed in the position of the first handle 210 relative to the door leaf 200 in this state. Furthermore, in order to improve the stability of the locking device 300 when the locking part 310 is unlocked to prevent the locking device 300 from shaking due to hull swaying or vibration, the position of the first handle 210 relative to the door leaf 200 also needs to be fixed in this state. Therefore, the connection position of the limiting member 400 and the limiting structure on the first handle 210 on the door leaf 200 is different in different states. The addition of the connecting part 410 on the limiting member 400 can meet this requirement. In addition, the length of the connecting part 410 is adjustable by setting a redundant length for the connecting part 410 or by making the connecting part 410 retractable.
[0072] For example, the connecting part 410 is at least one of a chain, rope, flexible tube, or telescopic spring with redundant length.
[0073] Furthermore, in order to strengthen the connection between the door leaf 200 and the door frame 100 after locking, the locking part 310 is provided with a first electromagnetic component, and the corresponding position of the door frame 100 is provided with a second electromagnetic component. When the locking part 310 and the door frame 100 are in the locked state, the first electromagnetic component and the second electromagnetic component are magnetically attracted, thereby improving the locking strength between the locking part 310 and the door frame 100. Moreover, this arrangement can also help the locking part 310 resist the displacement tendency caused by external forces such as ship swaying and vibration, thereby enhancing the stability of the locking between the locking part 310 and the door frame 100.
[0074] In this design, the first and second electromagnetic components, when energized, form an "S" pole (S) and an "N" pole (N), respectively, thus attracting each other magnetically. Therefore, when the locking part 310 is locked to the door frame 100, the first and second electromagnetic components are energized; when it is necessary to unlock the locking part 310, the first and second electromagnetic components are de-energized. The energization and de-energization of the first and second electromagnetic components are not limited to a switch button; a manual control method is also possible. The addition of the first and second electromagnetic components enhances the locking strength between the locking part 310 and the door frame 100 when they are locked.
[0075] In some embodiments, the first and second electromagnetic components can also be replaced by two permanent magnets made of magnetic materials, requiring no external energy drive. The closer the locking part 310 is to the door frame 100, the greater the magnetic force; the farther the locking part 310 is from the door frame 100, the smaller the magnetic force. Of course, the size of the first and second electromagnetic components must be considered to avoid them being too large, resulting in excessive magnetic attraction and making unlocking the locking part 310 from the door frame 100 too difficult.
[0076] In addition, in some embodiments, the locking part 310 and the door frame 100 can be connected by adding bolt holes, buckles, pin holes, etc., so that after the locking part 310 and the door frame 100 are locked, they can be fixed by manual operation.
[0077] In some embodiments, such as Figures 1 to 3 As shown, the hatch 10 also includes a threshold 500, which is located on the side of the passage space closest to the ground, i.e., vertically. In the passage space, the threshold 500 is located below the door leaf 200. The threshold 500 is movably connected to the door frame 100 and sealed to the door leaf 200. The threshold 500 can be opened or closed relative to the passage space. With this configuration, when the threshold 500 is open relative to the passage space, it facilitates the passage of people and goods, especially for children, the elderly, wheelchair users, and heavy goods, thereby improving the accessibility, practicality, and applicability of the hatch 10. It should be noted that when the threshold 500 needs to be opened relative to the passage space, the door leaf 200 on the same hatch 10 also needs to be opened relative to the passage space. However, when the threshold 500 is closed relative to the passage space, there is no restriction on the opening or closing of the door leaf 200.
[0078] For example, the connection between the threshold 500 and the door frame 100 is a hinge connection. The threshold 500 and the door leaf 200 can be sealed together by providing a seal 700 on at least one of the side of the door leaf 200 facing the threshold 500 and the side of the threshold 500 facing the door leaf 200. This ensures that when both the door leaf 200 and the threshold 500 are closed relative to the passage space, the two are sealed together to prevent seawater, rainwater and wind from entering the ship's cabin 610 from the gaps between them, thereby improving the sealing performance of the hatch 10.
[0079] Additionally, in some embodiments, such as Figures 1 to 3 As shown, the hatch 10 also includes a step 800. The step 800 is provided on both sides of the threshold 500 facing the interior 610 and the exterior of the ship's cabin, and is detachably connected to the threshold 500. When the hatch 10 does not need to open the threshold 500 for passage, because the threshold 500 has a certain height, people entering and exiting the cabin can step over the threshold 500 by stepping on the step 800, thereby increasing the applicability of the hatch 10. When the threshold 500 needs to be opened, and there is a large flow of people or a wide cargo area, the step 800 on the threshold 500 can be removed to avoid the step board affecting the passage space, thereby further improving the applicability of the hatch 10.
[0080] In some specific embodiments, reference continues to be made to Figures 1 to 3 As shown, the number of thresholds 500 on the hatch 10 is one, two, etc., and the number of steps 800 on the side of the hatch 10 facing the interior 610 of the ship and the side facing the exterior of the ship are the same as the number of thresholds 500.
[0081] For example, the hatch 10 is provided with two thresholds 500. The two thresholds 500 are symmetrically arranged about the center line of the door frame 100. The two sides of the two thresholds 500 are respectively hinged to the door frame 100. Thus, opening either or both of the two thresholds 500 can open part of the passage space. When the flow of people needing to pass is small or the width of the goods is narrow, only half of the passage space can be opened by opening one of the thresholds 500 and one door leaf 200. When the flow of people needing to pass is large or the width of the goods is wide, all the door leaves 200 and thresholds 500 in the passage space can be opened, thereby further improving the applicability and passage of the hatch 10.
[0082] Here is a supplementary explanation: when multiple door panels 200 and multiple thresholds 500 are installed in the passage space of hatch 10, such as... Figure 2 , Figure 4 and Figure 6As shown, the connections between door leaf 200 and door frame 100, between threshold 500 and door frame 100, between two adjacent door leaves 200, between two adjacent thresholds 500, and between adjacent door leaves 200 and thresholds 500 are all sealed. The sealing method involves installing a sealing element 700 at the connection point. The sealing element 700 is installed on at least one of the door leaf 200 and door frame 100, at least one of the threshold 500 and door frame 100, at least one of two adjacent door leaves 200, at least one of two adjacent thresholds 500, and at least one of adjacent door leaves 200 and thresholds 500. This improves the overall sealing performance of the hatch 10, preventing seawater, rainwater, and wind from entering the ship's cabin 610 through gaps in the hatch 10. For example, the sealing element 700 can be a rubber sealing strip, silicone sealing strip, etc.
[0083] In addition, combined Figure 1 and Figure 7 As shown, the threshold 500 has a stop structure 510 on the side facing the interior 610 of the ship's cabin. When the threshold 500 is closed relative to the passage space, the stop structure 510 abuts against the door frame 100. It should be noted that the threshold 500 can only open or close the passage space in the direction facing outwards from the ship's cabin. That is, the thresholds 500 on the hatch 10 provided in this application embodiment are all outward-opening thresholds 500. The setting of the stop structure 510 on the threshold 500 allows the threshold 500 to be fixed to the door frame 100 when the threshold 500 is closed relative to the door frame 100. When the door 200 is closed, the stop structure 510 can only be released from the door frame 100 from inside the ship's cabin 610. Personnel outside the ship's cabin cannot perform this operation. Therefore, while increasing the passage of the hatch 10, it also enhances the relative fixation strength and anti-theft performance between the threshold 500 and the door frame 100.
[0084] In some embodiments, the stop structure 510 is at least one of a columnar structure, a block structure, and a plate structure. For example, the stop structure 510 is a stop pin with a columnar structure. The stop pin can move relative to the threshold 500. When the threshold 500 is in a closed state relative to the passage space, the stop pin extends relative to the threshold 500 to abut against the door frame 100, thereby restricting the threshold 500 from moving in the direction toward the outside of the ship's cabin and locking the threshold 500 in the passage space.
[0085] Combination Figure 1 and Figure 8As shown, when the sill 500 is open relative to the passage space, the sill 500 has a stop structure 510 on the side facing the ship's cabin 610, and a stop part 520 on the ship's outer deck 600. When the sill 500 is open relative to the passage space, the stop structure 510 and the stop part 520 abut against each other, thereby preventing the sill 500 from rotating relative to the door frame 100 due to the swaying and vibration of the ship when it is open, thus improving the stability of the sill 500 when it is open and improving the stability of the cabin door 10.
[0086] For example, the stop portion 520 is at least one of a groove and a protrusion, such as... Figure 8 As shown, the stop part 520 is a protrusion with a slot. When the threshold 500 is opened relative to the passage space, the stop structure 510 retracts into the threshold 500. When the threshold 500 is in the open state relative to the passage space, the stop structure 510 extends out of the threshold 500, inserts into the slot, and abuts against the protrusion. Of course, the stop part 520 may not have a slot on the protrusion, but the position of the protrusion should correspond to the maximum position that the threshold 500 can open. When the threshold 500 is opened to the maximum position relative to the passage space, the stop structure 510 extends out of the threshold 500 and abuts against the side of the protrusion away from the threshold 500 to fix the position of the threshold 500 in the open state.
[0087] To further improve the locking strength of the entire hatch 10 when it is closed, that is, the strength when both the door leaf 200 and the threshold 500 are fixed relative to the door frame 100, the door leaf 200 has a first locking structure. When the locking part 310 is locked to the door frame 100, the door leaf 200 is locked to the door frame 100 through the first locking structure, thereby enhancing the connection strength between the door leaf 200 and the door frame 100.
[0088] In addition, the threshold 500 has a second locking structure 530. When the threshold 500 is in a closed state relative to the passage space, the threshold 500 is locked to the door frame 100 through the second locking structure 530, thereby further enhancing the connection strength between the threshold 500 and the door frame 100.
[0089] In some embodiments, the door leaf 200 has a first locking structure while the threshold 500 has a second locking structure 530. When the door leaf 200 and the threshold 500 are in a closed or locked state relative to the door frame 100, the door leaf 200 is locked to the door frame 100 by the first locking structure, and the threshold 500 is locked to the door frame 100 by the second locking structure 530, thereby enhancing the connection strength of the entire hatch 10.
[0090] For example, the first locking structure and the second locking structure 530 include, but are not limited to, a reverse-pull lock, a telescopic arm, etc., wherein, the return Figure 1 and Figure 2 As shown, the reverse-locking buckle includes a screw bolt and a reverse plate. The screw bolt passes through the reverse plate and is rotatably connected to the door leaf 200 or the sill 500. When the sill 500 or the door leaf 200 and the door frame 100 are in the closed state, the reverse plate is rotated relative to the screw bolt so that one end of the reverse lock rests on the door frame 100. Then, the screw bolt is rotated relative to the door leaf 200 or the sill 500 to tighten the screw bolt, so that the reverse plate exerts a force on the door frame 100 towards the outside of the ship's cabin. Conversely, the reverse plate and the door leaf 200 or the sill 500 will be subjected to a reaction force exerted by the door frame 100 towards the inside of the ship's cabin 610, thereby locking the door leaf 200 or the sill 500 to the door frame 100, thereby enhancing the connection strength between the door leaf 200 or the sill 500 and the door frame 100; in addition, the first When the locking structure and the second locking structure 530 are telescopic arms, one end of the telescopic arm is fixedly installed on the door leaf 200 or the threshold 500, and the other end is fixedly installed on the door frame 100. The fixing methods include, but are not limited to, bolt and nut connection, snap connection, pin connection, bonding, welding, etc. In addition, the telescopic arm is equipped with a drive device, including, but not limited to, hydraulic drive device, pneumatic drive device, electromagnetic drive device, etc. When the door leaf 200 or the threshold 500 is in the closed state relative to the door frame 100, the drive device can drive the telescopic arm to retract to the length corresponding to the relative distance between the two in the locked state, so that the telescopic arm gives the door leaf 200 or the threshold 500 a pulling force towards the ship cabin 610, thereby improving the connection strength between the door leaf 200 or the threshold 500 and the door frame 100.
