Description

Anti-vibration and anti-strong-impact overturning locking mechanism for sheet metal table body for ship Technical Field The utility model relates to the technical field of locking mechanisms, in particular to an anti-vibration and anti-strong-impact overturning locking mechanism for a sheet metal platform body for a ship. Background In the ship operation environment, the sheet metal table body needs to have a turnover function to adapt to different working conditions, and meanwhile, strict requirements of vibration resistance and impact resistance must be met. However, the conventional flip locking mechanism has the following defects and disadvantages under the conditions of high dynamic load, strong vibration and impact of the ship: 1) The impact resistance is insufficient. The existing locking mechanism adopts a common bolt or a simple bolt structure, when a ship encounters strong vibration working conditions such as wave impact or weapon emission, the locking mechanism is easy to loosen or even lose efficacy, so that the platform body is turned accidentally, and potential safety hazards exist. 2) The locking reliability is low. Traditional mechanism relies on manual locking, and complex operation just is difficult to ensure that locking force is even, and slight displacement probably appears under long-term vibrations environment, influences equipment stability. 3) The dynamic adaptability is poor. The existing mechanism usually adopts a rigid locking mode, lacks of a buffer design, and is easy to generate stress concentration under continuous vibration or instant impact, so that structural deformation or fatigue damage is caused. 4) Fast operation is limited. Although the degree of automation can be improved by partial hydraulic or electric locking mechanisms, the structure is complex, the maintenance is difficult, and the mechanism is easy to corrode in the marine environment with high salt fog and high humidity, so that the mechanism is invalid and the reliability is reduced. 5) Structural limitations. The common steel or aluminum alloy locking part is easy to wear under long-term impact load, and the existing mechanism lacks of modularized design, has high replacement cost after damage, and affects the operation efficiency of the ship. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides an anti-vibration and anti-strong-impact turnover locking mechanism of a sheet metal table body for a ship, which solves the problem of poor anti-vibration effect of the sheet metal table body.
