Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and particularly relates to an anti-piracy lock for steel doors of ships. Background Art

[0002] At present, the door locks on ships are generally steel door locks, which have poor anti-theft performance and deficiencies such as being easy to open. Since most pirates aim to rob property, when a ship sails and enters areas with pirates, the cabins on the open deck of the ship, such as storage rooms, spare parts rooms, paint rooms, and bosun's stores, etc., are the main targets of their robbery, and the property is extremely easy to be robbed. In addition, after the ship docks at the wharf, the ship's staff are busy loading and unloading goods and neglect management, resulting in the theft of open deck cabins. These cabins all use ordinary locks, which can be easily opened by hand or with a hammer or crowbar. Based on this situation, an anti-piracy lock for steel doors that can prevent smashing, prying, and theft is designed, which has important practical significance. Summary of the Invention

[0003] The purpose of the utility model is to solve the deficiencies of the existing steel door locks on ships, such as poor anti-theft performance and being easy to open, and to provide an anti-piracy lock for steel doors of ships that is simple to manufacture, convenient to operate, has good anti-theft effect, high safety performance, and low cost.

[0022] First of all, it should be noted that the following will specifically illustrate the specific structure, characteristics, and advantages of the present utility model by way of examples. However, all descriptions are only for the purpose of explanation and should not be construed as forming any limitation to the present utility model. In addition, any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the drawings, can still be arbitrarily combined or deleted between these technical features (or their equivalents) to obtain more other embodiments of the present utility model that may not be directly mentioned herein. Additionally, for the sake of simplifying the drawings, the same or similar technical features may only be marked in one place in the same drawing.

[0023] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] Embodiment 1

[0025] As Figures 1-5 shown, a pirate-proof lock for a ship steel door provided in this embodiment includes a lock body 1 and a lock core; a sunken locking space 6 is provided on the lock body, a threaded mounting hole 7 is provided at the bottom of the locking space, and a bolt insertion groove 8 is opened on the side wall of the locking space;

[0026] The lock core includes a threaded post 9, one end of the threaded post is fixedly provided with a head 10, and the peripheral side of the head forms a polygonal shape;

[0027] When locking, the bolt is inserted into the locking space through the bolt insertion groove, the threaded post of the lock core passes through the bolt and is connected to the threaded mounting hole, and by screwing in the lock core, the head realizes pressing on the bolt, and after locking the bolt, the head is located in the locking space.

[0028] It further includes a key 3, and a groove 2 matching the polygonal structure of the head is formed on the key.

[0029] It should be noted that the external shape structure of the lock body is not important. The purpose of setting the sunken locking space is to make the head located in the locking space after locking the bolt, so that non-staff members cannot unlock the lock or increase the difficulty of unlocking without suitable tools when unlocking, and try to avoid the loss of property in a short time; in this embodiment, preferably, the lock body can adopt a columnar structure, a cylindrical sunken locking space is provided at one end of the lock body, and a bolt insertion groove is opened on one side of the locking structure for inserting the bolt. The height of the insertion groove matches the thickness of the bolt. It should be noted that in order to better achieve the bolt locking effect, holes can be considered to be opened on the bolt. When the lock core is locked, the threaded post passes through the hole on the bolt and is screwed into the threaded mounting hole. When the threaded post is screwed in, the head presses on the bolt, increasing the locking effect on the bolt.

[0030] As an example, in this embodiment, as Figure 3 shown, the peripheral side of the head forms a regular pentagon structure. Correspondingly, a groove structure matching the regular pentagon structure is formed on the key, and the inner wall of the groove structure is also a regular pentagon structure;

[0031] In addition, to make it more convenient to lock or unlock the bolt, it can be considered that a support body 4 is fixedly connected to the key, and a wrench 5 is installed on the support body; in this embodiment, to make the key more labor-saving during use, it can be considered that the key is machined from an iron rod, the support body is welded to the end, the support length is fixed, a φ12mm round hole is opened at the end of the support body, the wrench is inserted into the round hole and is perpendicular to the support body, and the wrench is made of φ10mm round steel, which is simple to manufacture, increases the force arm, and saves time and effort.

[0032] When using this anti-pirate lock, the bolt M is inserted into the lock body through the bolt insertion groove, the lock core is slowly inserted along the direction of the lock body and the bolt, inserted to the threaded mounting hole, and the lock core is slowly screwed in so that the lock core is completely meshed with the threads of the lock body. Finally, the key is used to increase the torque to make the connection between the lock core and the lock body firm. When unlocking is required, the key is used to cooperate for unlocking.

[0033] For the anti-pirate lock for ship steel doors in this application, the lock core is completely embedded in the lock body to form a concave shape, and the key adopts an internal polygon structure, with a unique form. Outsiders cannot unlock it without a special key. This anti-pirate lock is simple in structure and good in anti-theft performance compared with existing mechanical locks and brass locks.

[0034] It can be considered that the lock body is machined from an iron rod to reduce the amount of welding. The manufacture and use of this anti-pirate lock are very convenient and can be reused multiple times.

[0035] The above embodiments have described the present invention in detail, but the above content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
