Lifting type tribed

Abstract

The invention relates to a lifting type tribed which comprises two end racks. Back plates are arranged between vertical edges on the same sides of the two end racks, lower, middle and upper beds are arranged between the end racks and the back plates, and four corners of the lower bed are connected to two ends of the lower edges of the two end racks. The lifting type tribed is characterized in thatthe end racks are of cavity platy structures, and vertical guide rails are arranged in the two vertical edges; upper wheel seats and upper pulleys are arranged at two ends of the inner side faces oftop plates of the end racks, and two lower wheel seats and two lower pulleys are arranged at two ends of the inner sides of bottom plates of the end racks; upper and lower slide blocks are arranged inthe vertical guide rails, and two corresponding rope holes are formed in the upper and lower slide blocks in the same end rack and four corners of the upper, middle and lower beds; vertical straightslots are formed in the inner side walls of the end racks, and the four corners of the upper and middle beds are separately connected to the corresponding upper and lower slide blocks through the vertical straight slots; annular steel wire ropes wind between the four upper pulleys and the eight lower pulleys; and the upper and lower slide blocks are separately locked to the annular steel wire ropes in corresponding positions. The lifting type tribed can convert between two-layered bed and the tribed, and is small in occupied area and can save the space.

Description

technical field [0001] The invention relates to a three-layer bed. Specifically, it is a liftable three-layer bed that can adjust the distance between the upper and lower bunks. Especially suitable for ships or occasions with small spaces. Background technique [0002] As everyone knows, the beds for people to have a rest on ships mainly contain bunk beds or triple beds at present. These bunk beds or triple beds are all fixed, and can not be converted between bunk beds and triple beds with the number of users, so that it takes up a lot of space and wastes the valuable space on the ship. Contents of the invention [0003] The problem to be solved by the present invention is to provide a marine descending three-layer bed. The lift-type three-layer bed can be converted between two-layer and three-layer beds, occupies less space and can save space. [0004] The above-mentioned problem to be solved by the present invention is realized by the following technical solutions: ...

Problems solved by technology

These bunk beds or triple beds are all fixed, and cannot be converted between bunk beds and triple beds according to the number of users, which makes it take up more space and wastes the valuable space on the ship.
