DETAILED DESCRIPTION

[0042] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0043] At present, shipboard equipment generally requires locks to fix the equipment on the ship to prevent the equipment from being stolen. However, since the shipboard equipment does not originally have a locking function, an external lock is needed to lock the shipboard equipment. The general external lock is a padlock, but the padlock is generally only suitable for openable and closable door covers. Padlocks are not suitable for shipboard equipment with relatively large size. Therefore, the traditional method requires an additional iron chain to be wrapped around the shipboard equipment and then locked with a padlock, which makes the opening and closing operations relatively complicated.

[0044] In order to solve the above problems, this embodiment provides a marine lock, which includes two main bodies: a lock tube 1 and a lock body.

[0045] like Figure 1-2 As shown, the lock tube 1 has an open port, and the end of the lock tube 1 opposite to the open port is set as a closed port. The lock tube 1 is hollow so that a lock cavity is formed inside the lock tube 1. The open port is connected to the lock cavity, and the equipment on the ship can enter the lock cavity from the open port.

[0046] A slot 12 is provided on the side of the lock tube 1. The width of the slot 12 on the radial cross section of the lock tube 1 is a first width. On the radial cross section of the lock tube 1, the maximum width of the lock tube 1 is a second width. The first width is smaller than the second width. Figure 3 , Figure 4 As shown, the lock cavity is used to accommodate a local marine component 100. The radial cross-sectional width of the local marine component 100 needs to be smaller than the second width and larger than the first width. After the local marine component 100 is placed in the lock cavity, it is confined in the lock cavity. At this time, the local marine component 100 can be exposed outside the lock tube 1 through the slot 12. The local marine component 100 can be connected to other onboard equipment through the slot 12, and is used to lock onboard equipment such as engines.

[0047] The lock body is connected to the open port, and the lock body and the open port are detachably connected. When the lock body is connected to the open port, it is used to restrict the local marine component 100 in the lock cavity, so that the local marine component 100 cannot be taken out of the lock tube 1; when locking is not needed, the lock body is removed from the open port, and the local marine component 100 can be taken out of the lock tube 1.

[0048] In this embodiment, the lock tube 1 is set to a cylindrical structure. At this time, on the radial section of the lock tube 1, the maximum width of the lock tube 1 is the diameter of the lock tube 1. At this time, the width of the local marine component 100 on the radial section only needs to be smaller than the diameter of the lock tube 1 and larger than the first width.

[0049] In other embodiments, the lock tube 1 can also be set to a rectangular structure, in which case the maximum width of the lock tube 1 on the radial section can be the diagonal length of the lock tube 1 on the radial section; assuming that there is a local marine component 100 at this time, the width of the local marine component 100 on the radial section is smaller than the diagonal length of the lock tube 1 and larger than the side width of the lock tube 1 on the radial section, this type of local marine component 100 can also be inserted into the lock cavity along the diagonal direction.

[0050] In this embodiment, the slot 12 is set as a long strip slot, and the slot 12 is formed by opening along a set direction starting from the open port, and the set direction is the axial direction of the lock tube 1, so that the local marine component 100 inserted into the lock tube 1 moves along the axial direction of the lock tube 1.

[0051] In this embodiment, the marine component includes a partial marine component 100 and a connecting part 200. The partial position of the marine component for being placed in the lock tube 1 is called the partial marine component 100, and the partial position exposed outside the lock tube 1 is the connecting part 200; the diameter of the connecting part 200 on the radial cross section of the lock tube 1 is smaller than the first width, the partial marine component 100 is confined in the lock cavity, and the connecting part 200 extends to the outside of the lock tube 1 through the slot 12 to connect to the designated marine equipment. During assembly, the partial marine component 100 and the connecting part 200 can be connected in advance, the partial marine component 100 is partially placed in the lock tube 1, and then the lock body is connected to the open port of the lock tube 1, and the connecting part 200 extends to the outside of the lock tube 1 through the slot 12 to connect to the designated marine equipment, so as to achieve the effect of locking the designated marine equipment.

[0052] In addition, the local marine component 100 and the connecting part 200 can be separated. The local marine component 100 is provided with a threaded hole, and the connecting part 200 is a bolt. After the local marine component 100 is placed in the lock cavity, the connecting part 200 is screwed into the threaded hole of the local marine component 100. The connecting part 200 is connected to a designated marine equipment, and the designated marine equipment can also be locked.

[0053] The lock tube 1 may be provided with an upper locking position, through which the lock tube 1 can be locked with the lock body. In this embodiment, the upper locking position is an opening on the lock body, through which the lock tube 1 and the lock body are locked together to prevent the partial marine component 100 from falling out of the lock tube 1. One end of the lock body is placed in the lock cavity through the open port, and the lock body is provided with a first pin hole 33; the upper locking position is a second pin hole 11 provided on the side of the lock tube 1; when the first pin hole 11 is directly opposite to the second pin hole 33, the first pin hole 11 is connected with the second pin hole 33 to insert the lock pin 9. In the axial direction of the lock tube 1, the length of the slot 12 is greater than the depth of the lock body in the lock cavity, so as to provide sufficient space for the connecting part 200 to extend.

[0054] In this embodiment, Figure 5 to Figure 15 As shown, the lock body includes:

[0055] The lock core has a first lock hole, and the first lock hole is used to insert a key to drive the lock core to rotate; a first groove 52 is provided on the side of the lock core;

[0056] The lock head 3, the lock tube 1 is sleeved on the lock head 3, and a first pin hole 33 is provided on the side surface of the lock head 3;

[0057] A second groove 91 is provided on the side of the locking pin 9. When the lock core is rotated until the first groove 52 is opposite to the first pin hole 33, the locking pin 9 is inserted into the first pin hole 33 through the second pin hole 11; when the locking pin 9 is inserted into the first pin hole 33, the lock core is rotated until the lock core is inserted into the second groove 91 to achieve locking.

[0058] Among them, Figure 8 As shown, the lock head 3 has a first cavity 34 and a first pin hole 33, the first cavity 34 partially overlaps with the first pin hole 33, and the lock core is located in the first cavity 34; in the axial direction of the first pin hole 33, the projection surface of the first pin hole 33 is the first projection surface; the projection surface of the lock core in the axial direction of the first pin hole 33 is the second projection surface;

[0059] When the first projection plane and the second projection plane do not overlap at all, the locking pin 9 can be inserted into or taken out of the first pin hole 33; when the locking pin 9 is located in the first pin hole 33, the lock core is rotated until the first projection plane and the second projection plane partially overlap so that the lock core and the locking pin 9 are locked with each other.

[0060] Specifically, Figure 7 to Figure 9As shown, the lock head 3 includes a lock cover 8, a first lock part 31 and a second lock part 32. The diameter of the first lock part 31 is larger than that of the second lock part 32. The lock cover 8 is clamped on the first bottom surface of the first lock part 31. The lock cover 8 is provided with an opening for inserting a key. The second lock part 32 is fixed on the second bottom surface of the first lock part 31. A first cavity 34 is provided in the lock head 3. The first cavity 34 axially passes through the first lock part 31 and the second lock part 32 and is used to accommodate the lock core.

[0061] A hole is opened on the side wall of the second lock portion 32 and extends in the radial direction to form a first pin hole 33, which extends radially and passes through a first cavity 34 for accommodating the lock core, so that the internal space of the first pin hole 33 partially intersects with the internal space of the first cavity 34.

[0062] like Fig. 9 As shown, a hole groove 35 is provided on the bottom surface of the end of the second lock portion 32, and the hole groove 35 is located opposite to the first cavity 34 for accommodating the lock core and is connected to the first cavity 34; the hole groove 35 is set to an incomplete circular structure, and the area of ​​the hole groove 35 is smaller than the area of ​​the same circle, which is used to limit the rotation angle of the lock core.

[0063] like Figure 8 As shown, in this embodiment, the position of the first cavity 34 is located on one side of the radial center line of the lock head 3, providing sufficient space for the first pin hole 33, so that the first pin hole 33 spans the radial center line of the second lock part 32, making full use of the limited space in the lock head 3.

[0064] A lock core is provided in the first cavity 34 of the lock head 3, and a first lock hole 71 is provided on a side of the lock core facing the lock cover 8. The position of the first lock hole 71 faces the opening position of the lock cover 8, so that the key can be inserted into the first lock hole 71 to drive the lock core to move. In this embodiment, the rotation of the key can drive the lock core to rotate in the first cavity 34 of the lock head 3, and the rotation angle is determined by the hole groove 35 on the bottom surface of the end of the second lock part 32. In this embodiment, the hole groove 35 is set to three quarters of the area of ​​a circle, and a limit block 54 is provided on a side of the lock core facing the bottom surface of the end of the second lock part 32. The limit block 54 is inserted into the hole groove 35. When the lock core rotates, when the limit block 54 abuts against any edge of the hole groove 35, the lock core reaches the maximum rotation angle in the rotation direction.

[0065] like Fig. 9 , Fig.15As shown, in this embodiment, the lock core includes a lock housing 7, a lock core 5 and a plurality of lock pieces 6; a first lock hole 71 is provided on the lock housing 7, one end of the lock core 5 is inserted into the lock housing 7, and a cavity is formed between the lock core 5 and the lock housing 7, and the cavity is used to accommodate a plurality of lock pieces 6. A second lock hole 62 is provided at the central position of each lock piece 6, and a plurality of lock pieces 6 are stacked together and placed in the cavity together, and the second lock holes 62 of all lock pieces 6 are aligned to form a key channel for inserting a key; some lock pieces 6 have the same locking pieces 61 extending outward in the same direction, and when all the lock pieces 6 are stacked together, the locking pieces 61 in the same direction are used to be stuck between the two pressing pieces of the lock core 5, so that the rotation of the lock piece 6 is synchronized with the rotation of the lock core 5.

[0066] like Fig.14 , Fig.15 As shown, the lock core 5 includes a first lock core part 51 and a second lock core part 53. A first groove 52 is provided on the peripheral side of the first lock core part 51, and the first groove 52 can be a semicircular groove; the second lock core part 53 is composed of two pressing plates surrounding the edges of the first lock core part 51. Each pressing plate can be set to an arc surface structure so that the second lock core part 53 can be fully inserted into the lock shell 7 and tightly attached to the inner wall of the lock shell 7. At this time, the lock plate 6 is inserted into the cavity formed between the pressing plate and the lock shell 7, and the unlocking and locking states can be switched after the key is inserted.

[0067] The unlocking and locking state switching of this embodiment is realized by the cooperation between the lock core and the lock pin 9. The lock pin 9 is formed by high-strength stainless steel, and the diameter of the lower side of the lock pin 9 is less than or equal to the diameter of the first pin hole 33 so that the lock pin 9 can be inserted into the first pin hole 33. Fig.13 As shown, two symmetrical second grooves 91 can be provided on the cylindrical circumferential side of the lock pin 9, and the second grooves 91 can be semicircular or annular grooves. A first pin hole 33 is provided on the side wall of the lock head 3, and the lock pin 9 can be inserted into the first pin hole 33 of the lock head 3. When the second groove 91 on the lock pin 9 is engaged with the column of the first lock core part 51 of the lock core 5, the lock pin 9 can be locked, and the lock pin 9 cannot be taken out at this time, achieving the locking effect; at this time, when the lock core 5 is rotated so that the first groove 52 on the column of the first lock core part 51 is directly opposite to the second groove 91 on the lock pin 9, the engagement state between the two is released, and the lock pin 9 can be taken out from the first pin hole 33 of the lock head 3 at this time, achieving the unlocking effect.

[0068] Among them, the first pin hole 33 extends radially in the lock head 3, passes through the first cavity 34 axially extending in the lock head 3 for accommodating the lock core, and the internal space of the first pin hole 33 partially intersects with the internal space of the first cavity 34; at this time, it is assumed that the first pin hole 33 and the first lock core part 51 are projected along the axial opening direction of the first pin hole 33, and in the axial opening direction of the first pin hole 33, the projection surface of the first pin hole 33 is the first projection surface; the first lock core part 51 is projected along the axial opening direction of the first pin hole 33 to obtain the second projection surface; when the lock pin 9 is not inserted into the first pin hole 33, if the first projection surface corresponding to the first pin hole 33 partially overlaps with the second projection surface corresponding to the first lock core part 51, the space in the first pin hole 33 is blocked by the column body of the first lock core part 51, so that the lock pin 9 cannot be inserted into the first pin hole 33. The first lock core part 51 is continuously rotated. When the first lock core part 51 is rotated to a position where the first groove 52 thereof faces the first pin hole 33, the first projection surface corresponding to the first pin hole 33 and the second projection surface corresponding to the first lock core part 51 do not overlap at all. At this time, the space inside the first pin hole 33 is not blocked, and is sufficient for the lock pin 9 to be inserted into the first pin hole 33. When the lock pin 9 is inserted into the first pin hole 33, the first lock core part 51 is continuously rotated. The second projection surface corresponding to the first lock core part 51 and the first projection surface corresponding to the first pin hole 33 partially overlap. At this time, the column of the first lock core part 51 can be inserted into the second groove 91 of the lock pin 9. At this time, the lock pin 9 cannot be removed from the first pin hole 33, and the locked state is achieved.

[0069] The function of the lock core in the lock is to rotate synchronously with the rotation of the key after the key is inserted. During the rotation process, it cooperates with the lock pin 9 to achieve the unlocking and locking effects of the lock, and can also drive the first sensing component 4 installed at the tail end of the lock core to rotate synchronously.

[0070] In some embodiments, the lock core can also be a digital lock or a pin lock or other structures to achieve rotation. The structures of digital locks and pin locks have been disclosed in the prior art, and the structures of digital locks and pin locks are not described in detail here. It is only necessary that they can be rotated under the action of the key, and cooperate with the lock pin 9 during the rotation process to achieve unlocking and locking.

[0071] In the case of the above-mentioned lock body structure, during the actual assembly process of the lock tube 1, the local marine component 100, which may be a lock handle on the ship lock engine, is first inserted into the lock cavity from the open port of the lock tube 1 and snapped into the slot 12, thereby limiting the lock handle on the ship lock engine in the lock cavity of the lock tube 1, and then the lock tube 1 is sleeved on the end of the lock head 3 from the open port of the lock tube 1. At this time, the second pin hole 11 on the lock tube 1 is opposite to the first pin hole 33 on the lock head 3. The lock pin 9 is inserted into the second pin hole 11 and the first pin hole 33, and the key is turned to clamp the lock core and the lock pin 9 to achieve the locking effect.

[0072] The combined structure of the lock head 3, the lock pin 9 and the lock tube 1 in this embodiment has the characteristics of simple structure, simple and reasonable use and convenient disassembly, which is different from the traditional integrated boat lock; the base 2 is included in the lock, and various electronic components are built into the base 2. An alarm component, such as a speaker 21, can also be provided on the base 2 to allow the boat lock to have an alarm function; the base 2 adopts a modular design, which is more convenient and quick to repair, replace or charge, so that the boat lock has a safe and not easy to be damaged effect.
