Description

Technical Field

[0001] The invention relates to a locking anti-theft component, an anti-theft door and a ship comprising the same. Background Art

[0002] The traditional anti-theft lock nose adopts the structure of bolt and pentagonal nut. The head of the bolt is welded to the door frame, and the connecting plate is welded on the door plate. A connecting hole is opened at the corresponding position of the bolt. The screw part of the bolt passes through the connecting hole, and the nut is tightened and fixed from the other side of the connecting plate, thereby achieving the purpose of anti-theft. In actual use, the nut must be completely removed to open the anti-theft door, which is inconvenient for actual operation. At the same time, the nut is easy to lose after being completely removed.

[0003] The anti-theft lock nose is mainly used on ships. The actual working environment of the ship is humid, and the anti-theft lock nose is easily corroded, requiring frequent maintenance and lacking in aesthetics. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the nuts of anti-theft doors which are locked and protected against theft by bolts and nuts must be completely disassembled during use, which is inconvenient for actual operation and the nuts are easy to be lost, and to provide a locking anti-theft component, an anti-theft door and a ship comprising the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A locking anti-theft assembly, comprising a first locking member, a second locking member and a locking device;

[0007] The first locking member is used to be fixedly connected to the door frame, the second locking member is used to be detachably connected to the door panel and can move between a locked position and an unlocked position relative to the door panel, the second locking member is connected to the first locking member through the locking device, and when the second locking member switches between the locked position and the unlocked position, the locking device is always connected to the first locking member and the second locking member;

[0008] When the second locking member is located at the locking position, the second locking member is connected to the door panel, and the locking device is used to limit the movement of the second locking member relative to the first locking member;

[0009] When the second locking member is located at the unlocking position, the second locking member is disconnected from the door panel to avoid the movement trajectory of the door panel relative to the door frame, and the locking device is used to allow the second locking member to move relative to the first locking member.

[0010] In this solution, the locking anti-theft assembly includes a first locking member, a second locking member and a locking device, and the first locking member and the second locking member are locked by the locking device. The second locking member is detachably connected to the door panel and can move between a locked position and an unlocked position relative to the door panel. When the second locking member is connected to the door panel, the second locking member is in a locked position; when the second locking member is not connected to the door panel, the second locking member is in an unlocked position. The second locking member is movably connected to the first locking member or the second locking member is movably connected to the first locking member through the locking device. This connection method avoids the loss of parts that may be caused by complete disassembly, simplifies the use of the locking anti-theft assembly, and helps to improve the user experience of the locking anti-theft assembly.

[0011] When the second locking member is in the locked position, the second locking member is connected to the door panel, the locking device restricts the second locking member from moving relative to the first locking member, and the door panel is fixed to the door panel by the locking anti-theft assembly, thereby playing a locking anti-theft role.

[0012] When the second locking member is in the unlocking position, the locking device is used to allow the second locking member to move relative to the first locking member to avoid the movement track of the door panel relative to the door frame, and the second locking member is disconnected from the door panel. At this time, the door panel can be opened and closed normally according to its actual opening mode.

[0013] Preferably, the second locking member includes a snap-fit ​​connection with the door panel.

[0014] In this solution, the second locking member and the door panel are fixed by respectively providing corresponding protruding parts and recessed parts on the door panel and the second locking member, so that when the second locking member is in the locked position, the connection between the second locking member and the door panel is more reliable, thereby achieving a better locking and fixing effect.

[0015] Preferably, the second locking member is switched between the locking position and the unlocking position by rotating relative to the first locking member.

[0016] In this solution, the second locking member is rotatable relative to the first locking member. When the second locking member needs to switch between the locked position and the unlocked position, the locking device allows the second locking member to rotate relative to the first locking member. When the door panel needs to be unlocked relative to the door frame, the second locking member rotates relative to the first locking member to reach the unlocked position, avoiding the movement trajectory of the door panel relative to the door frame, so that the door panel can be opened and closed relative to the door frame; when the door panel needs to be locked relative to the door frame, after the second locking member rotates relative to the first locking member to reach the locked position, the locking device locks and fixes the first locking member and the second locking member, so that the door panel is locked relative to the door frame, achieving the effect of anti-theft locking.

[0017] Preferably, the locking device comprises a first locking portion and a second locking portion, the first locking portion comprises a matching hole, and the second locking portion is passed through the matching hole and connected to the first locking portion.

[0018] In this solution, the first locking portion includes a matching hole, the second locking portion is inserted into the matching hole and connected to the first locking member, and the second locking portion can be fixedly connected to the first locking portion through the matching hole to achieve locking of the locking device. By setting a physical structure lock, the structure of the locking anti-theft component is simplified, the manufacturing cost of the locking anti-theft component is reduced, and the actual use process of the locking anti-theft component can also be simplified, which is convenient for actual use and operation.

[0019] Preferably, the first locking member includes a connecting member, a volume cavity is arranged inside the connecting member, and the first locking portion is inside the volume cavity.

[0020] In this solution, the first locking member includes a connecting member, which is fixed to the door frame. A volume cavity is arranged inside the connecting member, and the connecting member realizes the connection between the locking device and the door frame, and the first locking part is protected by the volume cavity, so as to prevent the first locking part from being directly corroded by dust, rain or humid environment in the use environment, thereby extending the service life of the locking device; and avoiding the operation of completely disassembling the locking device relative to the door frame during actual use, thereby simplifying the actual use experience of the locking anti-theft component and avoiding the problem of parts loss of the locking anti-theft component.

[0021] Preferably, the first locking member comprises a connecting plate, the connecting plate is fixedly connected to an end of the connecting member away from the door frame, and the first locking portion is fixed to the connecting plate;

[0022] When the second locking member is in the locking position, the connecting plate abuts against the second locking member.

[0023] In this solution, the first locking part is fixed to the connecting plate. When the second locking part is locked or unlocked relative to the first locking part, sliding between the second locking part and the first locking part is avoided, resulting in failure to lock or unlock smoothly. This facilitates the operation of the staff during actual use and improves the use experience of the locking anti-theft component.

[0024] When the second locking piece is in the locked position, the connecting plate abuts against the second locking piece, which facilitates the locking and unlocking of the locking device and avoids excessive squeezing or stretching of the locking device, thereby ensuring the anti-theft locking effect of the locking device and extending the service life of the locking and anti-theft components.

[0025] The connecting plate protects the connecting piece and the first locking part inside the volume cavity of the connecting piece, preventing the connecting piece from being deformed due to excessive local force during the door panel and switching process, thereby affecting the locking effect of the locking anti-theft component; at the same time, it can better protect the first locking part from corrosion and pollution from the external environment, thereby extending the service life of the locking anti-theft component.

[0026] Preferably, the second locking portion includes a limiting member;

[0027] The second locking portion is disposed through the first locking member and the second locking portion;

[0028] The limiting member is disposed at the end of the second locking portion close to the first locking portion, and the limiting member is used to prevent the first locking portion from falling off relative to the second locking portion.

[0029] In this solution, the second locking part is inserted through the first locking member and the second locking member, and is connected to the first locking member inside the volume cavity of the first locking member. A stopper is provided at the end of the second locking member close to the first locking member to prevent the second locking member from falling off relative to the first locking member, thereby avoiding the loss of parts of the locking anti-theft assembly during use and improving the user experience of the locking anti-theft assembly.

[0030] A theft-proof door comprises the above-mentioned locking and theft-proof assembly.

[0031] In this solution, the anti-theft door is locked and unlocked by means of a locking anti-theft component. In actual use, the locking anti-theft component can prevent the loss of parts and components, and is easy to operate and convenient for staff to operate.

[0032] Preferably, when the anti-theft door is a hinged door, the second locking member is switched between the locked position and the unlocked position by rotating relative to the first locking member;

[0033] Alternatively, when the anti-theft door is a sliding door, the second locking member is switched between the locked position and the unlocked position by moving relative to the first locking member.

[0034] In this solution, when the anti-theft door is a hinged door, the second locking member avoids the movement trajectory of the door panel relative to the door frame by rotating relative to the first locking member, and after the rotation, there is no obstruction in the direction perpendicular to the front of the door panel, thereby realizing the switching between the locked position and the unlocked position;

[0035] When the anti-theft door is a sliding door, the second locking member moves relative to the first locking member to avoid the movement trajectory of the door panel relative to the door frame, thereby achieving switching between the locked position and the unlocked position.

[0036] The positive and progressive effects of the present invention are: a locking anti-theft assembly, the anti-theft assembly comprising a first locking member, a second locking member and a locking device;

[0037] The first locking member is used to be fixedly connected to the door frame, the second locking member is used to be detachably connected to the door panel and can move between a locked position and an unlocked position relative to the door panel, the second locking member is connected to the first locking member through a locking device, and in the process of the second locking member switching between the locked position and the unlocked position, the locking device is always connected to the first locking member and the second locking member;

[0038] When the second locking member is in the locked position, the second locking member is connected to the door panel, and the locking device is used to limit the movement of the second locking member relative to the first locking member;

[0039] When the second locking member is located at the unlocking position, the second locking member is disconnected from the door panel to avoid the movement trajectory of the door panel relative to the door frame, and the locking device is used to allow the second locking member to move relative to the first locking member.

[0040] The locking anti-theft assembly includes a first locking member, a second locking member and a locking device, and the first locking member and the second locking member are locked by the locking device. The second locking member is detachably connected to the door panel and can move between a locked position and an unlocked position relative to the door panel. When the second locking member is connected to the door panel, the second locking member is in a locked position; when the second locking member is not connected to the door panel, the second locking member is in an unlocked position. The second locking member is movably connected to the first locking member or the second locking member is movably connected to the first locking member through the locking device. This connection method avoids the loss of parts that may be caused by complete disassembly, simplifies the use of the locking anti-theft assembly, and helps to improve the user experience of the locking anti-theft assembly.

[0041] When the second locking member is in the locked position, the second locking member is connected to the door panel, the locking device restricts the second locking member from moving relative to the first locking member, and the door panel is fixed to the door panel by the locking anti-theft assembly, thereby playing a role of locking and anti-theft;

[0042] When the second locking member is in the unlocking position, the locking device is used to allow the second locking member to move relative to the first locking member to avoid the movement track of the door panel relative to the door frame, and the second locking member is disconnected from the door panel. At this time, the door panel can be opened and closed normally according to its actual opening mode.

[0043] A ship comprises a hull and the above-mentioned anti-theft door.

[0044] In this solution, the anti-theft door and the locking anti-theft device are used for steel doors with anti-theft requirements on ships. The environment on the ship is relatively humid. The use of the above-mentioned locking anti-theft components and anti-theft doors can extend the service life of the locking anti-theft device, ensure a reliable anti-theft effect, simplify the operation of the staff, and is also beneficial to the appearance of the anti-theft door and the ship.

[0059] In specific implementation, Figure 1As shown, the locking anti-theft assembly includes a first locking member 1, a second locking member 2 and a locking device 3, and the first locking member 1 and the second locking member 2 are locked by the locking device 3. In specific implementation, the locking assembly can achieve locking connection by means of a mechanical structure, or by means of magnetic adsorption or adhesive connection.

[0060] In this embodiment, the first locking member 1 and the second locking member 2 are directly connected through the locking device 3, and a connecting component can also be provided to realize the movable connection between the first locking member 1 and the second locking member 2, for example, a hinge is provided at the side end of the second connecting member 11 away from the door panel 4 and is movably connected to the first connecting member 11. In this case, the locking device 3 only needs to have a locking function.

[0061] The second locking member 2 is detachably connected to the door panel 4 and can move between a locked position and an unlocked position relative to the door panel 4. When the second locking member 2 is connected to the door panel 4, the second locking member 2 is in a locked position; when the second locking member 2 is not connected to the door panel 4, the second locking member 2 is in an unlocked position. The second locking member 2 is movably connected to the first locking member 1 or the second locking member 2 is movably connected to the first locking member 1 through the locking device 3. This connection method avoids the loss of parts that may be caused by complete disassembly, simplifies the use of the locking anti-theft component, and is conducive to improving the user experience of the locking anti-theft component.

[0062] When the second locking member 2 is in the locked position, the second locking member 2 is connected to the door panel 4, and the locking device 3 limits the movement of the second locking member 2 relative to the first locking member 1. The door panel 4 is fixed to the door panel 4 through the locking anti-theft assembly, which plays a role in locking and anti-theft. When the second locking member 2 is in the unlocked position, the locking device 3 is used to allow the second locking member 2 to move relative to the first locking member 1 to avoid the movement trajectory of the door panel 4 relative to the door frame 5, and the second locking member 2 is disconnected from the door panel 4. At this time, the door panel 4 can be opened and closed normally according to its actual opening method.

[0063] In specific implementation, Figure 1 As shown, the second locking member 2 and the door panel 4 are fixed by respectively providing corresponding protruding parts and recessed parts on the door panel 4 and the second locking member 2, so that when the second locking member 2 is in the locked position, the connection between the second locking member 2 and the door panel 4 is more reliable, and a better locking and fixing effect is achieved. Among them, the protruding part can be provided on the second locking member 2, and the corresponding recessed part can be provided on the door panel 4; or the recessed part can be provided on the second locking member 2, and the corresponding protruding part can be provided on the door panel 4.

[0064] In this embodiment, a concave portion is provided on the second locking member 2, and a corresponding convex portion is provided on the door panel 4. Such a setting does not need to destroy the structure of the door panel 4 itself, and can be directly set after the door panel 4 is installed relative to the door frame 5, and when the locking anti-theft component needs to be replaced, it can be directly removed for replacement, which is convenient for the actual use of the locking anti-theft component.

[0065] As a preferred embodiment, the second locking member 2 is switched between the locked position and the unlocked position by rotating relative to the first locking member 1. When the second locking member 2 needs to switch between the locked position and the unlocked position, the locking device 3 allows the second locking member 2 to rotate relative to the first locking member 1. When the door panel 4 needs to be unlocked relative to the door frame 5, the second locking member 2 rotates relative to the first locking member 1 to reach the unlocked position, avoiding the movement trajectory of the door panel 4 relative to the door frame 5, so that the door panel 4 can be opened and closed relative to the door frame 5; when the door panel 4 needs to be locked relative to the door frame 5, after the second locking member 2 rotates relative to the first locking member 1 to reach the locked position, the locking device 3 locks and fixes the first locking member 1 and the second locking member 2, so that the door panel 4 is locked relative to the door frame 5, achieving the effect of anti-theft locking.

[0066] In this embodiment, the locking device 3 connects the first locking member 1 and the second locking member 2, and the locking device 3 is set as a cylinder at the connection end of the first locking member 1 and the second locking member 2, which can directly realize the rotation of the second locking member 2 relative to the first locking member 1. Another connecting component can also be set to realize the rotation of the second locking member 2 relative to the first locking member 1.

[0067] In specific implementation, Figure 1 As shown, the locking device 3 includes a first locking portion 31 and a second locking portion 32. The first locking portion 31 includes a matching hole. The second locking portion 32 is inserted into the matching hole and connected to the first locking portion 31. The second locking portion 32 can be fixedly connected to the first locking portion 31 through the matching hole to achieve locking of the locking device 3. By setting a physical structural lock, the structure of the locking anti-theft component is simplified, the manufacturing cost of the locking anti-theft component is reduced, and the actual use process of the locking anti-theft component can also be simplified, which is convenient for actual use and operation.

[0068] In a specific implementation, the first locking member 1 includes a connecting member 11, a volume cavity 12 is arranged inside the connecting member 11, and the first locking portion 31 is inside the volume cavity 12. The first locking member 1 includes a connecting member 11, and the connecting member 11 is fixed to the door frame 5. The volume cavity 12 is arranged inside the connecting member 11, and the connecting member 11 realizes the connection between the locking device 3 and the door frame 5, and the first locking portion 31 is protected by the volume cavity 12.

[0069] In this embodiment, the locking anti-theft component is installed on the anti-theft door of the hull with anti-theft requirements. The use environment is relatively humid, which is easy to cause corrosion to the locking anti-theft component. The provision of the volume cavity 12 can protect the first locking part 31 and extend the service life of the locking device 3; avoid the operation of completely disassembling the locking device 3 relative to the door frame 5 during actual use, simplify the actual use experience of the locking anti-theft component, and avoid the problem of loss of parts of the locking anti-theft component.

[0070] In the case of specific facts, Figure 1 As shown, the first locking member 1 includes a connecting plate 13, the connecting plate 13 is fixedly connected to an end of the connecting member 11 away from the door frame 5, and the first locking portion 31 is fixed to the connecting plate 13;

[0071] When the second locking member 2 is in the locking position, the connecting plate 13 abuts against the second locking member 2 .

[0072] In this solution, the first locking portion 31 is fixed to the connecting plate 13. When the second locking portion 32 is locked or unlocked relative to the first locking portion 31, sliding between the second locking portion 32 and the first locking portion 31 is avoided, resulting in failure to lock or unlock smoothly. This facilitates the operation of the staff during actual use and improves the use experience of the locking anti-theft component.

[0073] When the second locking member 2 is in the locked position, the connecting plate 13 abuts against the second locking member 2, which facilitates the locking and unlocking of the locking device 3 and avoids excessive squeezing or stretching of the locking device 3, thereby ensuring the anti-theft locking effect of the locking device 3 and extending the service life of the locking and anti-theft components.

[0074] The connecting plate 13 protects the connecting member 11 and the first locking portion 31 inside the volume cavity 12 of the connecting member 11, thereby preventing the connecting member 11 from being deformed due to excessive local force during the door panel 4 and the switching process, thereby affecting the locking effect of the locking anti-theft component; at the same time, it can better protect the first locking portion 31 from corrosion and pollution from the external environment, thereby extending the service life of the locking anti-theft component.

[0075] As a preferred implementation, Figure 1 As shown, the second locking portion 32 is provided through the first locking member 1 and the second locking member 2, and is connected to the first locking portion 31 inside the volume cavity 12 of the first locking member 1. A stopper 321 is provided at the end of the second locking portion 32 close to the first locking portion 31, which is used to prevent the second locking portion 32 from falling off relative to the first locking portion 31, thereby avoiding the loss of parts of the locking anti-theft assembly during use and improving the user experience of the locking anti-theft assembly.

[0076] The anti-theft door is locked and unlocked by a locking anti-theft component. In actual use, the locking anti-theft component can avoid the loss of parts and is easy to operate, making it convenient for staff to operate.

[0077] In specific implementation, when the anti-theft door is a hinged door, the second locking member 2 rotates relative to the first locking member 1. When it is necessary to unlock the anti-theft locking assembly, unlock the locking device 3, move the second locking member 2 away from the door panel 4 and rotate the second locking member 2, so that the long side of the second locking member 2 is perpendicular to the ground, avoiding the movement trajectory of the door panel 4 relative to the door frame 5, and after the second locking member 2 is rotated, it does not restrict the rotation of the door panel 4 relative to the door frame 5 in the direction perpendicular to the front of the door panel 4. When it is necessary to lock the anti-theft locking assembly, turn the second locking member 2 back to the locked position and engage it with the door panel 4, fix the second locking member 2 and the door panel 4, lock the locking device 3, restrict the movement of the second locking member 2 relative to the first locking member 1, and lock the door panel 4 relative to the door frame 5.

[0078] When the anti-theft door is a sliding door, the second locking member 2 is movable relative to the first locking member 1. When it is necessary to unlock the anti-theft locking assembly, in addition to locking the locking device 3, the second locking member 2 is moved in a direction away from the door panel 4, so that there is a certain space between the second locking member 2 and the first locking member 1, and the space can be used for the door panel 4 to move in a direction away from the door frame 5, and the extension of the side of the door panel 4 toward the door frame 5 will not contact the extension of the side of the door frame 5 toward the door panel 4, and the door panel 4 can be pushed and pulled relative to the door frame 5. When it is necessary to lock the anti-theft locking assembly, the second locking member 2 is moved in a direction close to the door panel 4 to a locking position and is engaged with the door panel 4, the second locking member 2 and the door panel 4 are fixed, the locking device 3 is locked, the movement of the second locking member 2 relative to the first locking member 1 is restricted, and the door panel 4 is locked relative to the door frame 5.

[0079] In specific implementation, the anti-theft door and the locking anti-theft device are used for steel doors with anti-theft requirements on ships. The environment on the ship is relatively humid. The use of the above-mentioned locking anti-theft components and anti-theft doors can extend the service life of the locking anti-theft device, ensure a reliable anti-theft effect, simplify the operation of the staff, and is also beneficial to the appearance of the anti-theft door and the ship.
