Abstract
Description
Technical Field
[0001] This invention relates to the field of marine technology, and in particular to a door lock assembly and a method for ship escape. Background Technology
[0002] Ship anti-piracy devices are typically accessed through anti-piracy doors to secure areas, and can be locked or opened from the inside. However, when the path to the secure area is not limited to the door structure but also includes escape routes, anti-piracy devices that only support locking or opening from the inside will cause significant inconvenience.
[0003] In such situations, crew members must first enter the escape route through the anti-piracy door, close the fire door and the anti-piracy door and lock them from the inside, and then enter the safe area via the vertical ladder in the escape route. This process is not only cumbersome, but also far less efficient than entering the safe area directly through the anti-piracy door. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to address the issue that in the prior art, anti-piracy doors on ships are difficult to lock from the outside only, the door closing process is complicated, resulting in low escape efficiency and high risk factor, and to provide a door lock component and a ship escape method.
[0005] The present invention solves the above-mentioned technical problems through the following technical solution:
[0006] A door lock assembly includes a first locking part and a second locking part. The first locking part is disposed on a door panel, and the second locking part is disposed on a door frame or wall. The first locking part is used to connect with the second locking part. The second locking part includes a groove. The first locking part includes a latch and a spring. The spring is disposed within the first locking part, and one end of the spring is connected to the latch. The spring controls the extension and retraction of the latch. The latch is adapted to the groove, and the groove engages with the extended latch. The latch has a bevel mechanism on its surface, facing outwards from the door panel, and corresponding to the end of the second locking part near the first locking part. The latch includes two or more latch structures. The first locking part also includes a control part connected to the latch and disposed on the interior side of the door panel. The control part adjusts the position of the latch, and the end of the spring away from the latch is connected to the control part.
[0007] In this solution, by setting a latch with a beveled mechanism, and aligning the beveled mechanism with the end of the second locking part closest to the first locking part, when the door panel is pulled from the outside, the edge of the second locking part can be pushed by external force to push the beveled mechanism, thereby compressing the latch into the first locking part and simultaneously compressing the spring. When the beveled mechanism slides until the latch is inserted into the slot, the spring is released from its constraint and automatically returns to an unconstrained state, and the latch engages with the slot, thus achieving the effect of locking the door. In addition, by setting two or more latch structures, the strength, security, and anti-theft performance of the lock can be improved. At the same time, a control part is set on the first locking part to facilitate opening the door from the inside, making the operation convenient and efficient while also ensuring security.
[0008] Preferably, the control unit further includes a movable end, which is disposed on the side of the control unit away from the locking tongue. The movable end is provided with a pull buckle and is used to drive the control unit to move.
[0009] In this solution, by setting a mobile end on the control unit, and setting a pull buckle on the mobile end, the efficiency of opening the anti-piracy door from the inside is improved. The pull buckle makes it easy to use both hands to pull the high-elasticity spring at the same time, which makes the door opening more efficient and the operation more convenient.
[0010] Preferably, the first locking part further includes a housing, and a portion of the spring member and the locking tongue member are disposed inside the housing. The housing has an opening for the spring member and the control part to move.
[0011] In this solution, by setting a housing on the first locking part and placing the spring inside the housing, the spring is prevented from being exposed to air and rusting or being damaged by external forces, thus improving the safety performance of the lock.
[0012] Preferably, the second locking part further includes a latch body, the slot is formed in the latch body, and the latch body is installed on the side of the door frame or the wall facing the interior.
[0013] Preferably, the first locking part is bolted to the door panel; and / or, the second locking part is bolted to the door frame or the wall.
[0014] Preferably, the slot further includes a top end and a bottom end, and a roller mechanism is provided on the top end and / or the bottom end, the roller mechanism being in contact with the surface of the extended locking tongue.
[0015] In this solution, a roller mechanism is provided on the top and / or bottom surface of the slot, so that the roller mechanism contacts the surface of the extended locking tongue. After the door panel is closed from the outside, when the spring pushes the locking tongue into the slot, the locking tongue can be more smoothly and quickly locked into the slot, completing the locking step at high speed and improving locking efficiency.
[0016] Preferably, the inclined plane mechanism is further provided with chamfered structures at both ends; and / or, the surface of the inclined plane mechanism is coated with a lubricant.
[0017] In this solution, by setting chamfered structures at both ends of the inclined mechanism, the friction between the latch and the second locking part is reduced during the process of the inclined mechanism contacting the second locking part and the latch sliding into the slot when the door is closed, thus reducing the possibility of component damage and improving closing efficiency.
[0018] Preferably, the first locking part is installed on the interior side of the door panel, and the second locking part is installed on the interior side of the door frame or the wall.
[0019] A ship escape method, which enables escape by operating an anti-piracy door having a door lock assembly as described above, the ship anti-piracy escape method comprising the following steps:
[0020] S1: Pull and close the anti-piracy door from the outside of the cabin;
[0021] S2: The anti-piracy door automatically locks after being closed, completing the locking operation of the anti-piracy door in the safe area;
[0022] S3: Crew members enter the safe area via the stairs.
[0023] Preferably, the staircase is adjacent to the anti-piracy door and located outside the cabin, and the staircase is a step staircase.
[0024] In this solution, when pirates board the ship, crew members can pull and close the anti-piracy door from the outside of the cabin and then enter the safe area via the stairs. This effectively solves the problems of long escape times, high difficulty, and high danger associated with current ships that have both anti-piracy doors and stairs. Crew members need to close the anti-piracy door from the outside of the cabin and then lock it inside before they can climb the ladder in the escape passage to the safe area. This solution greatly improves the efficiency of crew escape. Moreover, crew members can enter the safe area via stairs, which is more convenient and faster than climbing the ladder in the escape passage in existing technologies.
[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.
[0026] The positive and progressive effects of this invention are as follows:
[0027] This invention features a latch with a beveled mechanism, positioned so that the beveled mechanism corresponds to the end of the second locking part closest to the first locking part. When the door panel is pulled from the outside, the edge of the second locking part can be pushed by external force against the beveled mechanism, compressing the latch into the first locking part and simultaneously compressing the spring. Once the beveled mechanism slides into the latch's slot, the spring is released from its constraint and automatically returns to an unconstrained state, allowing the latch to engage with the slot, thus locking the door. Furthermore, by using two or more latch structures, the strength, security, and anti-theft performance of the lock are improved. A control unit is also provided on the first locking part, facilitating opening the lock from the inside, making operation convenient and efficient while maintaining security.

[0048] The present invention is further illustrated below by way of embodiments, but the invention is not limited to the scope of the embodiments described herein. Experimental methods in the following embodiments that do not specify specific conditions were performed according to conventional methods and conditions, or as selected according to the product instructions.
[0049] like Figures 1-4As shown, this embodiment provides a door lock assembly 01, which includes a first locking part 001 and a second locking part 002. The first locking part 001 is disposed on the door panel, and the second locking part 002 is disposed on the door frame or wall. The first locking part 001 is used to connect with the second locking part 002, and the second locking part 002 includes a slot 21. The first locking part 001 includes a latch 11 and a spring 12. The spring 12 is disposed inside the first locking part 001, and one end of the spring 12 is connected to the latch 11. The spring 12 is used to control the extension and retraction of the latch 11. When the door is closed, the latch 11 and the second locking part 002 are engaged. 02 is pushed into the first locking part 001 by the pressure of the second locking part 002. At this time, the locking tongue 11 simultaneously compresses the spring. When the locking tongue 11 aligns with the slot 21, the locking tongue 11 slides into the slot 21, and at the same time, the spring 12 releases pressure, pushing the locking tongue 11 into the slot 21, completing the locking step. The locking tongue 11 is adapted to the slot 21, and the slot 21 is used to engage with the protruding locking tongue 11. The surface of the locking tongue 11 is provided with a bevel mechanism 111, which faces outward of the door panel. The bevel mechanism 111 is corresponding to the end of the second locking part 002 near the first locking part 001. In this embodiment, the end of the inclined mechanism 111 near the outside corresponds to the section of the second locking part 002 near the first locking part 001. When the door is closed, when the latch 11 contacts the second locking part 002, the edge of the second locking part 002 applies a partial pushing force towards the door panel and parallel to the door panel to the inclined mechanism 111, causing the latch 11 to be pushed into the first locking part 001 by this pushing force. The inclined mechanism 111 plays the role of transmitting the pushing force and reducing resistance. When the end of the inclined mechanism 111 facing the inside is aligned with the slot 21, the latch 11 is completely aligned with the slot 21. The locking tongue 11 slides into the slot 21 to complete the locking operation. The locking tongue 11 includes two or more locking tongue structures 112. In this embodiment, two locking tongue structures 112 are interconnected and both are connected to the spring 12. The two locking tongue structures 112 are the same size, parallel to each other, and corresponding to the slot 21. The first locking part 001 also includes a control part 13, which is connected to the locking tongue 11. The control part 13 is located on the interior side of the door panel and is used to adjust the position of the locking tongue 11. The end of the spring 12 away from the locking tongue 11 is connected to the control part 13. The spring 12 can be stretched to a length of ( Figure 1 (The range indicated by the middle arrow) exceeds 135mm. In this embodiment, the end of the control unit 13 facing the second locking member is connected to the latch member 11. The control unit 13 is connected to the latch member 11 through the spring member 12. When the latch member 11 is displaced, it will drive the control unit 13 to move. At the same time, the movement of the control unit 13 can also control the relative displacement of the latch member 11. The first locking part 001 is installed on the indoor side of the door panel, and the second locking part 002 is installed on the indoor side of the door frame or wall.
[0050] In this embodiment, by providing a latch 11 with a bevel mechanism 111, and by arranging the bevel mechanism 111 corresponding to the end of the second locking part 002 near the first locking part 001, when the door panel is pulled from the outside, the edge of the second locking part 002 can be pushed by external force to push the bevel mechanism 111, thereby compressing the latch 11 into the first locking part 001 and compressing the spring 12. When the bevel mechanism 111 slides into the slot 21 where the latch 11 is inserted, the spring 12 is released from its constraint and automatically returns to an unconstrained state, and the latch 11 engages with the slot 21, thereby achieving the effect of locking the door. In addition, by providing two or more latch structures 112, the strength, security performance, and anti-theft performance of the lock can be improved. At the same time, a control part 13 is provided on the first locking part 001, which facilitates the door lock to be opened from the inside, making the operation convenient and efficient, while also ensuring security.
[0051] In other embodiments, the inclined surface mechanism 111 may be provided with pulley assemblies, gear assemblies, or other mechanisms to reduce friction and collision between the inclined surface mechanism 111 and the second locking part 002. The end of the spring member 12 away from the latch member 11 may also be connected to the first locking part 001 or other parts of the door panel to fix the relative position of the spring member 12 and prevent the spring member 12 from deviating from its position when the latch member 11 is displaced. In addition, the latch structures 112 may not be connected to each other. At the same time, the number of control units 13 can be adaptively adjusted according to the latch structure 112, and each latch can be controlled separately. This will not be elaborated further here.
[0052] like Figures 1-2 As shown, in this embodiment, the control unit 13 also includes a movable end 131. The movable end 131 is located on the side of the control unit 13 away from the latch 11. The movable end 131 is provided with a pull buckle. The movable end 131 is used to drive the control unit 13 to move. When closing the door, the latch 11 receives pressure from the second locking part 002. The latch 11 transmits a pushing force away from the second locking part 002 to the control unit 13, causing the control unit 13 to move accordingly. At this time, the movable end 131 also moves relative to other fixed parts of the first locking part 001. The end of the movable end 131 facing the latch 11 is connected to the spring 12. When opening the door, by operating the pull buckle on the movable end 131, the spring 12 is driven, which in turn drives the latch 11 to disengage from the slot 21, completing the door opening operation. The pull buckle form makes it easy to use both hands to pull the high-elasticity spring at the same time, resulting in higher door opening efficiency and more convenient operation.
[0053] Furthermore, in this embodiment, the first locking part 001 is bolted to the door panel. The first locking part 001 also includes a housing 14. A portion of the spring member 12 and the latch member 11 are disposed inside the housing 14. The housing 14 has an opening for the spring member 12 and the control part 13 to move. During the opening and closing of the door, the moving end 131 and the latch member 11 are both relatively displaced relative to the fixed part of the first locking part 001. Therefore, the housing 14 needs to reserve holes for the left and right movement of these two parts at the corresponding positions. At the same time, the spring member 12 is disposed inside the housing 14 so that the spring member 12 will not be exposed to the air and rust or be damaged by external forces, thereby improving the safety performance of the lock.
[0054] In other embodiments, the first locking part 001 can be fixedly connected to the door panel by means of screws or welding, and the spring member 12 can be partially or completely exposed without the protection of the housing 14 in order to realize part of the function of controlling the door opening and closing, or the housing 14 can be omitted, which will not be described in detail here.
[0055] like Figures 3-4 As shown, the second locking part 002 also includes a latch body 22, with a slot 21 formed in the latch body 22. The latch body 22 is installed on the side of the door frame or wall facing the interior. The second locking part 002 is bolted to the door frame or wall. The slot 21 also includes a top end and a bottom end. A roller mechanism 211 is provided on the top end. The roller mechanism 211 contacts the surface of the extended latch 11. When the latch 11 slides into the slot 21, the roller mechanism 211 provides a sliding thrust to the upper and lower surfaces of the latch 11 to reduce the friction between the upper and lower surfaces of the latch 11 and the top and bottom surfaces of the slot 21. This allows the latch 11 to be more smoothly and quickly engaged in the slot 21 when the spring 12 pushes the latch 11 into the slot 21 after the door panel is closed from the outside. This completes the locking process at high speed and improves locking efficiency.
[0056] In other embodiments, the second locking part 002 can be fixedly connected to the door panel by means of screws or welding, and the slot 21 can also be provided with a roller mechanism 211 on both the top and bottom surfaces or only on the bottom surface, or with a track or other structure that can reduce the friction of the locking tongue 11 being stuck in the slot 21, which will not be described in detail here.
[0057] like Figures 1-2 As shown, in this embodiment, the two ends of the inclined surface mechanism 111 are also provided with chamfer structures 1101 and the surface of the inclined surface mechanism 111 is coated with lubricant. The chamfer structure 1101 reduces the friction between the locking tongue 11 and the second locking part 002 during the process of the inclined surface mechanism 111 contacting the second locking part 002 and the locking tongue 11 sliding into the slot 21 when the door is closed, thereby reducing the possibility of component damage and improving the closing efficiency.
[0058] This invention also provides a ship escape method, which achieves escape by operating an anti-piracy door having the door lock assembly 01 described above. The ship anti-piracy escape method includes the following steps: S1: Pulling and closing the anti-piracy door from the outside of the cabin; S2: The anti-piracy door automatically locks after being closed, completing the locking operation of the anti-piracy door in the safe area; S3: Crew members enter the safe area via the stairs. The stairs are adjacent to the anti-piracy door and located on the outside of the cabin, and the stairs are step stairs.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
