Description

Technical Field

[0001] The utility model relates to the technical field of masts, in particular to a mast mechanism with a convenient disassembly and assembly structure. Background Art

[0002] A mast is a tall pole on a ship that is used to hang sails and flags, install antennas, and support observation platforms. It is a long wooden pole or a metal pole, usually erected vertically from the keel or centerboard of the ship, and can support the lower girders of the cross sails, the booms or the diagonal girders. The mast on a ship has many uses. For example, it is used to install signal lights, hang flags, and set up telegraph antennas. In addition, it can also support the cargo boom for hoisting and unloading cargo. The main function of the mast of a modern ship is to provide an installation platform for detection equipment such as radar. Therefore, based on the detection performance requirements of radar, the mast is naturally the higher the better. However, at the same time, any form of mast is a structure with its own inherent structural mechanical characteristics. The selection and design of the mast must meet mechanical indicators such as structural strength, vibration, and fatigue. Under the premise of similar loads, the mechanical properties of several structural forms are quite different. In terms of structural strength, the tower mast has an unshakable advantage. The tower mast is structurally integrated with the superstructure, and is designed with longitudinal and transverse frames like the hull structure. The wall plates and frames are subjected to stress at the same time, and both contribute to the strength. Therefore, compared with the lattice mast that relies on steel structure to balance the stress (including the tower-shaped mast with a skin applied on the lattice mast) and the relatively slender, small-cross-section cylindrical mast, the tower mast has the best structural strength and the greatest load-bearing capacity.

[0003] At present, when assembling ship parts on the market, the mast needs to be installed on the ship. In actual use, when the mast is installed on the ship, lighting components, radar and other parts need to be installed on the mast to facilitate the subsequent use of the mast mechanism. When installing the lighting components on the mast, multiple bolts are usually used to fix the lighting components one by one, and the bolts will be exposed to the outside for a long time, causing the bolts to rust and lock when the subsequent lighting components are disassembled and assembled for the second time, making the subsequent lighting components difficult to disassemble.

[0023] A mast mechanism with an easy-to-disassemble structure comprises a mast body 1 and a mounting ring 2 arranged on the outer wall of the mast body 1, a groove body 3 is opened inside the mounting ring 2, a disc 4 is arranged inside the groove body 3, a first magnet 5 is fixedly connected to the outer wall of the disc 4, a second magnet 6 is fixedly connected to the outer wall of the disc 4 away from the first magnet 5, a fixing rod 7 is fixedly connected to the inside of the groove body 3, a positioning block 8 is slidably connected to the outer wall of the fixing rod 7, a connecting rod 9 is fixedly connected to the outer wall of the positioning block 8, and a third magnet 10 is fixedly connected to the connecting rod 9 away from the positioning block 8, so that the disc 4 can drive the third magnet 10 to move inside the groove body 3 through the first magnet 5 and the second magnet 6.

[0024] In a preferred embodiment, the end of the positioning block 8 away from the fixing rod 7 passes through the outer wall of the mounting ring 2 and the positioning block 8 is slidably connected to the mounting ring 2. A positioning groove 11 is provided on the outer wall of the mast body 1. The positioning block 8 is slidably connected to the positioning groove 11. When the connecting rod 9 moves, the connecting rod 9 will move inside the groove body 3, so that the connecting rod 9 can drive the positioning block 8 to move inside the groove body 3.

[0025] In a preferred embodiment, a rotating rod 12 is fixedly connected to the outer wall of the disc 4, one end of the rotating rod 12 passes through the outer wall of the mounting ring 2 and the rotating rod 12 is rotatably connected to the mounting ring 2, and a first spring 13 is provided between the disc 4 and the slot body 3. When the rotating rod 12 moves, the rotating rod 12 will drive the disc 4 to move inside the slot body 3, and the disc 4 can drive the first spring 13 to move, and at the same time, the disc 4 drives the first magnet 5 and the second magnet 6 to move.

[0026] In a preferred embodiment, a stabilizing groove 14 is opened inside the mounting ring 2, a mounting groove 15 is opened on the outer wall of the mounting ring 2, a pull rod 16 is provided inside the stabilizing groove 14, and both ends of the pull rod 16 respectively pass through the mounting groove 15 and the outer wall of the mounting ring 2. The pull rod 16 is slidably connected to the mounting ring 2. When the pull rod 16 moves, the pull rod 16 will move inside the stabilizing groove 14, and at the same time, the pull rod 16 will move inside the mounting groove 15.

[0027] Working principle of the utility model: when the device is used and the mounting ring 2 needs to be disassembled for the second time, the rotating rod 12 is rotated at this time to make the rotating rod 12 rotate inside the slot body 3, and the rotating rod 12 drives the disc 4 to move at the same time, so that the disc 4 rotates inside the slot body 3, and the disc 4 drives the first spring 13 to move at the same time, so that the first spring 13 is twisted, and at this time the disc 4 can drive the first magnet 5 and the second magnet 6 to move, so that the first magnet 5 and the second magnet 6 move in a small circular motion inside the slot body 3, so that the first magnet 5 is away from the third magnet 10, so that the second magnet 6 reaches the side of the third magnet 10, and the second magnet 6 and the third magnet 10 repel each other, so that the third magnet 10 slides inside the slot body 3, and then the subsequent third magnet 10 can drive the connecting rod 9 to move, so that the connecting rod 9 slides inside the slot body 3, and the connecting rod 9 drives the positioning block 8 to move at the same time. The positioning block 8 slides inside the slot body 3, and the positioning block 8 slides on the outer wall of the fixing rod 7 at the same time, causing one end of the positioning block 8 to separate from the positioning slot 11. When the positioning block 8 is separated from the inside of the positioning slot 11, the mounting ring 2 is pulled at this time so that the mounting ring 2 can slide out from the outer wall of the mast, so that the new mounting ring 2 or the mounting ring 2 after overhaul returns to the initial position outside the mast. At this time, the positioning block 8 is located on one side of the positioning slot 11, and the rotating rod 12 is released. The twisting force of the first spring 13 causes the disc 4 to return to the initial position. The disc 4 will drive the first magnet 5 and the second magnet 6 to return to the initial position, so that the first magnet 5 is located on one side of the third magnet 10. The first magnet 5 and the third magnet 10 attract each other, so that the third magnet 10 drives the positioning block 8 to enter the inside of the positioning slot 11 through the connecting rod 9, so that the subsequent mounting ring 2 is convenient for secondary disassembly and installation, thereby facilitating the disassembly of the lighting components on the subsequent mast.

When the third magnet 10 moves, the third magnet 10 can drive the connecting rod 9 to move, so that the connecting rod 9 can drive the positioning block 8 to move.

[0030] The working principle of the utility model is as follows: when it is necessary to disassemble a single lighting lamp 21, the pull rod 16 is pulled at this time to make the pull rod 16 slide inside the stable groove 14, and the pull rod 16 simultaneously drives the extrusion plate 17 to move, so that the extrusion plate 17 slides inside the stable groove 14, and the extrusion plate 17 simultaneously squeezes the second spring 18, and one end of the pull rod 16 is simultaneously moved out from the inside of the engaging groove 20, and at this time, the lighting lamp 21 is pulled, so that the lighting lamp 21 drives the installation rod 19 to move, so that one end of the installation rod 19 is moved out from the inside of the installation groove 15, so that the lighting lamp 21 is convenient to disassemble and replace.
