Example one

The marine door lock device provided by the embodiment is used for a marine translation door.

Referring to fig. 1 to 11, the marine door lock device includes a mechanical lock mechanism and a trigger mechanism.

The triggering mechanism is connected between the driving mechanism of the marine sliding door and the mechanical lock mechanism, and when the mechanical lock mechanism is switched from a non-operation state to an operation state, the triggering mechanism can control the driving mechanism of the marine sliding door to be started and enable the mechanical lock mechanism to be unlocked or locked.

The non-operation state is a state in which the mechanical lock mechanism is not operated by an external force, and the operation state is a state in which the mechanical lock mechanism is operated by an external force. Generally, the non-operation state of the mechanical lock mechanism corresponds to a state in which the door 71 is opened or closed, and the operation state corresponds to an intermediate state in which the door 71 is switched between the opened state and the closed state, and the trigger mechanism is capable of unlocking the mechanical lock mechanism at the start time of switching the door 71 from the closed state to the opened state, and capable of locking the mechanical mechanism at the start time of switching the door 71 from the opened state to the closed state.

Because the mechanical lock mechanism needs external force to maintain the operation state, the mechanical lock mechanism is unlocked or locked through the trigger mechanism, the external force applied to the mechanical lock mechanism is cancelled after the trigger mechanism starts the driving mechanism of the marine sliding door, the purposes of automatic unlocking and automatic door opening can be achieved without keeping the operation state for a long time, labor can be saved, and the comfort degree of automatic door opening and closing is improved. Optionally, the external force is manual force.

The marine door locking device in this embodiment includes mechanical latch mechanism and trigger mechanism, only needs to exert external force to mechanical latch mechanism and makes mechanical latch mechanism switch over to there being the operating condition, touches trigger mechanism through the inside motion of mechanical latch mechanism, can make actuating mechanism be started to drive door leaf 71 removes and opens the door or closes the door, and in addition, trigger mechanism can make mechanical latch mechanism unblock or lock, thereby need not external force maintenance operating condition opening, closing the door in-process, can unblock before opening the door, lock after closing the door. Therefore, the marine door lock device can automatically unlock, lock and open and close the door on the basis of keeping the mechanical lock mechanism, thereby not only overcoming the problem of difficult manual opening, but also improving the use safety and reliability of the marine translation door under the marine bump ring.

In an alternative of this embodiment, the mechanical lock mechanism includes a first lock member 10 and a second lock member 11 that can be locked to or separated from each other.

The trigger mechanism comprises a switch member, a trigger member and a first drive member 13. The actuating member is connected to the first locking member 10 and moves toward or away from the switching member as the first locking member 10 moves, and the actuating member triggers the switching member in a contact manner and releases the switching member in a separated manner. The switch component is used for electrically connecting the driving mechanism, and when the switch component is triggered, the driving mechanism controls the driving mechanism to start. The first driving member 13 is connected with the second locking member 11 and can drive the second locking member 11 to move to the locking position or the unlocking position.

Wherein the locking position is the position of the mechanical lock mechanism in the inoperative state and the first locking member 10 and the second locking member 11 when they are locked to each other. The unlocking position is other than the locking position. Since any one of the first locking member 10 and the second locking member 11 is moved away from the locking position and reaches the corresponding unlocking position, the first locking member 10 and the second locking member 11 are in the unlocking state, and therefore, the function of unlocking the mechanical lock mechanism can be achieved regardless of whether the first locking member 10 or the second locking member 11 is moved away from the locking position. On the contrary, when the first locking member 10 and the second locking member 11 are located at the corresponding locking positions, the first locking member 10 and the second locking member 11 are in the locking state.

Specifically, in the process that a sailor automatically opens the marine sliding door through the marine door locking device, the mechanical lock mechanism is operated to enable the first locking member 10 to move, the touch member can be driven to be close to the switch member until the switch member is triggered, then the first locking member 10 is released, and due to the fact that no external force is applied, the first locking member 10 resets and drives the touch member to reset, at the moment, on one hand, the switch member is started to drive the driving mechanism to open the marine sliding door through the driving mechanism, on the other hand, the mechanical lock mechanism returns to the locking state due to the fact that the external force is removed from the first locking member 10, the switch member starts the first driving member 13, so that the first locking member 10 and the second locking member 11 are unlocked again, and the situation that the locking state of the mechanical lock mechanism obstructs the automatic door opening function of the driving mechanism can.

It can be understood that, during the automatic closing process of the translational marine door by the marine door locking device, the crew moves the first locking member 10 by operating the mechanical lock mechanism, on one hand, the switch member activates the driving mechanism to close the translational marine door by the driving mechanism, on the other hand, the switch member activates the first driving member 13 to move the second locking member 11 to the unlocking position until the first locking member 10 moves to the locking position, and then the first driving member 13 drives the second locking member 11 to move to the locking position, so that the first locking member 10 and the second locking member 11 are locked, and the mechanical lock mechanism is locked.

Optionally, the switch member comprises a micro switch, a push switch or a toggle switch or the like.

Optionally, the mechanical lock mechanism further comprises a lock box 201 with a handle 200, the lock box 201 is configured to be disposed on the door leaf 71, the first locking member 10 is disposed in the lock box 201, and the second locking member 11 is disposed in the door frame 70 for hidden installation.

In an alternative embodiment, the mechanical lock mechanism comprises a handle 200 connected to the first locking member 10, wherein rotating the handle 200 rotates the first locking member 10, the first locking member 10 is a first hook, and the trigger member is pivotally connected to the first locking member 10. The second locking member 11 includes a first pivot 12 and a second locking hook, the first driving member 13 is a retractable driving member, and the first driving member 13 can drive the second locking hook to rotate around the first pivot 12, so as to engage or disengage the first locking hook and the second locking hook.

The mechanical lock mechanism comprises a first lock hook and a second lock hook, the first lock hook and the second lock hook achieve the purposes of unlocking and locking through relative pivoting, and meanwhile, the purpose of driving a touch member to be close to or far away from a switch member can be achieved through a simple pivoting structure. Specifically, the first latch hook pivots toward the side of the switch member to drive the activating member to approach the switch member, and the first latch hook pivots away from the side of the switch member to drive the activating member away from the switch member.

Optionally, the second latch hook is pivotally connected to the door frame 70 by the first pivot shaft 12.

Further, the first driving member 13 is pivotally connected to the door frame 70 by a second pivot shaft 130.

In an alternative of this embodiment, the mechanical lock mechanism includes a handle 200 connected to the first locking member 10, the handle 200 is pushed and pulled to enable the first locking member 10 to slide toward or away from the second locking member 11, the first locking member 10 is a latch, and the trigger member abuts against the latch through the driving inclined plane to enable the moving direction of the trigger member to face or depart from the switch member; the second locking member 11 is a slider with an insertion hole and the first driving member 13 is capable of driving the slider closer to or away from the first locking member 10.

The mechanical lock mechanism comprises a bolt and a jack, wherein the bolt and a jack hook achieve the purposes of unlocking and locking through sliding, and meanwhile, the purpose of driving a touch component to be close to or far away from a switch component can be achieved through a simple driving inclined plane. Specifically, the pin slides towards the socket, driving the actuation member close to the switch member, and the pin slides away from the socket, driving the actuation member away from the switch member. In the using process, the latch is disposed in the lock case 201 and installed on the door 71, and the slider is slidably disposed in the door frame 70 to achieve the purpose of hidden installation.

Optionally, the driving ramp is angled at 45 ° to the sliding direction of the latch such that the direction of movement of the actuating member is perpendicular to the direction of movement of the latch.

It is understood that the first locking member 10 and the second locking member 11 may be in other forms besides the two forms of the first locking hook and the second locking hook, the latch and the receptacle, as long as the mutual locking and unlocking functions can be achieved. Accordingly, the connection relationship between the touch member and the first locking member 10, and the connection relationship between the first driving member 13 and the second locking member 11 are changed according to the structures of the first locking member 10 and the second locking member 11 and the locking manner, and are not limited to the above two manners. Any structure that can actuate the trigger member by the movement of the first locking member 10 to thereby trigger the switch member falls within the scope of the inventive concept of the present application, and any structure that can actuate the second locking member 11 by the first actuating member 13 to thereby lock or separate the second locking member 11 from the first locking member 10 falls within the scope of the inventive concept of the present application.

In an alternative of this embodiment, the triggering member includes a guide base 23 having a guide groove, a U-shaped wrapping 24, a first limiting portion 25, a second limiting portion 26, a triggering push rod 27, and a triggering plate 28.

That is, when the touch push rod 27 moves, the touch push plate moves along with the touch push rod 27, and meanwhile, the U-shaped edge 24 also moves synchronously, so that on one hand, the switch component can be triggered by the touch push plate, so that a sufficient contact area is ensured between the touch push plate and the switch component, and reliable triggering is realized, and on the other hand, the part in the installation space is separated from the external space by the U-shaped edge 24, so that the part in the installation space and a person outside the installation space can be protected at the same time.

The first limiting part 25 is connected with the guide base 23 and is positioned between the touch plate 28 and the first locking member, the second limiting part 26 is connected with the U-shaped edge 24 and is positioned between the first limiting part 25 and the touch plate 28, and when the first locking member 10 is in a non-operation state, the first limiting part 25 is abutted with the second limiting part 26. When the guide direction is the up-down direction, the second stopper portion 26 can reciprocate between the second stopper portion 26 and the opening and closing member along with the U-shaped wrapping 24.

Through the butt effect between first spacing portion 25 and the spacing portion 26 of second, on the one hand, can play the supporting role to U-shaped bordure 24, touch board 28 and touch push rod 27 under no operating condition to alleviate the bearing burden of first locking-component 10, on the other hand, when first locking-component 10 switched to no operating condition from having operating condition, first spacing portion 25 was the spacing portion 26 of second fall back and has played the stroke limit effect, avoided first spacing portion 25 excessively to fall back, thereby alleviateed the impact effect to first locking-component 10.
