Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of locking mechanisms, specifically a flipping locking mechanism for a ship's sheet metal platform that is resistant to vibration and strong impact. Background Technology
[0002] In the shipboard operating environment, sheet metal platforms need to be able to flip to adapt to different working conditions, while also meeting stringent requirements for vibration and impact resistance. However, traditional flipping and locking mechanisms have the following defects and shortcomings under the high dynamic loads, strong vibrations, and impacts of ships:
[0003] 1) Insufficient impact resistance. Existing locking mechanisms mostly use ordinary bolts or simple pin structures, which are prone to loosening or even failure when ships encounter strong vibrations such as wave impacts or weapon launches, leading to accidental overturning of the platform and posing a safety hazard.
[0004] 2) Low locking reliability. Traditional mechanisms rely on manual locking, which is cumbersome and makes it difficult to ensure uniform locking force. Under long-term vibration, slight displacement may occur, affecting the stability of the equipment.
[0005] 3) Poor dynamic adaptability. Existing mechanisms typically employ rigid locking methods and lack buffer design, making them prone to stress concentration under continuous vibration or instantaneous impact, leading to structural deformation or fatigue damage.
[0006] 4) Limited rapid operation. While some hydraulic or electric locking mechanisms can improve the degree of automation, they are complex in structure, difficult to maintain, and prone to corrosion in the high salt spray and high humidity marine environment, leading to mechanism failure and reduced reliability.
[0007] 5) Structural limitations. Ordinary steel or aluminum alloy locking components are prone to wear under long-term impact loads, and existing mechanisms lack modular design, resulting in high replacement costs after damage and affecting the efficiency of ship operations. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a flipping and locking mechanism for a shipboard sheet metal platform that is resistant to vibration and strong impact, thus solving the problem of poor vibration resistance of the sheet metal platform.
[0009] To achieve the above objectives, this utility model provides the following technical solution: a flipping and locking mechanism for a shipboard sheet metal platform that is resistant to vibration and strong impact, comprising a control body and a control surface. The control surface is located on the left side of the control body. Rotary shaft brackets are fixedly installed at both ends of the left side of the control body. Rotary shafts are rotatably connected inside the platform surfaces at both ends of the left side of the platform. The ends of the rotating shafts are rotatably connected to the upper ends of the rotating shaft brackets. Brackets are fixedly installed inside the bottom surface of the control surface, and gas springs are rotatably connected between adjacent brackets and rotating shaft brackets.
[0010] Preferably, the bottom of the control panel is symmetrically fixed with fixing blocks. The right sidewalls of the fixing blocks are all horizontal and fit against the sidewalls of the control panel. The lower end of each fixing block is provided with a threaded hole. The threaded hole is threaded with an anti-loosening hand-tightening bolt. The right end of the anti-loosening hand-tightening bolt is threaded through the inside of the fixing block and connected to the inside of the sidewall of the control panel, thereby facilitating the stable installation of the control panel.
[0011] Preferably, the anti-loosening hand-tightening bolt consists of a threaded post, a connecting rod, and a nut, and the diameter of the threaded post is larger than the diameter of the connecting rod. An auxiliary spring is sleeved on the outside of the anti-loosening hand-tightening bolt, and one end of the auxiliary spring is fixedly connected to the nut, thereby ensuring that the anti-loosening hand-tightening bolt is stable after installation.
[0012] Preferably, a shaft washer is sleeved between the shaft and the shaft bracket, and a table shaft baffle is fixedly installed on the outer side wall of the shaft bracket, thereby limiting the position of the shaft.
[0013] This utility model provides a flipping and locking mechanism for a sheet metal platform for ships that is resistant to vibration and strong impact. It has the following beneficial effects:
[0014] 1. This type of vibration-resistant and impact-resistant sheet metal platform tilting and locking mechanism for ships utilizes a gas spring-mechanical linkage composite locking mechanism. By combining a high-impact-resistant gas spring with a mechanical tilting and locking device, it retains the buffering advantages of the gas spring while ensuring absolute fixation under extreme conditions through mechanical hard locking, thus improving reliability.
[0015] 2. The flipping and locking mechanism of the ship's sheet metal platform, which is resistant to vibration and strong impact, has a quick release mechanism and adopts a gas spring-assisted design to achieve rapid lifting of the platform during use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 This utility model provides a flipping and locking mechanism for a shipboard sheet metal platform that is resistant to vibration and strong impact. It includes a control body 9 and a control surface 10. The control surface 10 is located on the left side of the control body 9. Rotary shaft brackets 2 are fixedly installed at both ends of the left side of the control body 9. Rotary shafts 4 are rotatably connected inside the platform surfaces at both ends of the left side of the platform 9. The ends of the rotating shafts 4 are rotatably connected to the upper ends of the rotating shaft brackets 2. Brackets 12 are fixedly installed inside the bottom surface of the control surface 10, and gas springs 5 are rotatably connected between adjacent brackets 12 and rotating shaft brackets 2. Fixing blocks 6 are symmetrically fixedly installed at the bottom of the control surface 10. The right sidewalls of the fixing blocks 6 are horizontal and fit against the sidewalls of the control body 9. Threaded holes 11 are provided inside the lower ends of the fixing blocks 6, and anti-loosening hand-tightening bolts 8 are threadedly connected inside the threaded holes 11. The right end of each component is connected to the inside of the side wall of the control panel 9 via an internal thread penetrating the fixing block 6. The anti-loosening hand-tightening bolt 8 consists of a threaded post, a connecting rod, and a nut, with the diameter of the threaded post being larger than that of the connecting rod. A secondary spring 7 is sleeved on the outside of the anti-loosening hand-tightening bolt 8, and one end of the secondary spring 7 is fixedly connected to the nut. A rotating shaft washer 3 is sleeved between the rotating shaft 4 and the rotating shaft bracket 2. A table rotating shaft baffle 1 is fixedly installed on the outer side wall of the rotating shaft bracket 2. This structure achieves the flipping function through the rotating shaft 4 and the locking function through the fixing block 6, allowing the anti-loosening hand-tightening bolt 8 to enter the inside of the threaded hole 11 until it is threadedly connected to the inside of the side wall of the control panel 9. The angle of flipping is limited by the gas spring 5. Compared with other similar support or buffer mechanisms, the gas spring 5 has advantages such as strong impact resistance, self-locking safety, and maintenance-free operation, providing buffer support for the equipment.
[0022] It should be noted that, in this embodiment, as Figure 1-3 As shown, the structure achieves the flipping function through the rotating shaft 4 and the locking function through the fixing block 6, so that the anti-loosening hand-tightening bolt 8 enters into the interior of the threaded hole 11 until it is threaded into the interior of the side wall of the control console body 9. The flipping angle is limited by the gas spring 5. Compared with other similar support or buffer mechanisms, the gas spring 5 has the advantages of strong impact resistance, self-locking safety, and maintenance-free operation, providing buffer support for the equipment.
