Description

Technical Field

[0001] The utility model belongs to the technical field of supplies for cruise ships, in particular to a table leg fixing structure for cruise ships. Background Art

[0002] On a cruise ship, a table is an essential piece of interior furniture.

[0003] When a cruise ship encounters wind and waves while sailing on the sea, it will cause severe turbulence. Ordinary tables will inevitably cause large displacement or even tipping, posing a great safety hazard. Therefore, on cruise ships, bolts, anti-wave hooks, and lashing straps are usually used to fix the table to the cruise ship.

[0004] Existing furniture fixing devices for interior decoration of cruise ships, such as CN114104207B, adopt a structure in which a slider and a slide groove are set at the bottom of the chair. This solution requires making grooves on the bottom plate, which is very destructive to the cruise ship floor, and the inside of the groove is prone to water accumulation and impurities, etc. This fixing structure is relatively complex and has poor aesthetics. In addition, since the floor is connected with two supporting legs, the bottom space utilization rate is small, which is not suitable for the fixed use of a single table. Therefore, based on the above situation, it is of great significance to propose a cruise table leg fixing structure with simple structure, high strength, good stability and aesthetics, little destructiveness to the cruise ship floor, not easy to accumulate water and impurities, high space utilization, and easy installation and disassembly for fixing the table on the cruise ship.
