Description

Technical Field

[0001] The utility model relates to the technical field of roto-molded water tanks, in particular to a thick-walled, hollow, lightweight roto-molded water tank. Background Art

[0002] Traditional water tanks are usually made of metal or hard plastic. These materials are often deformed due to collisions or bumps in daily use, which reduces the service life of the water tank. In addition, metal water tanks may cause water pollution due to rust, and some low-quality hard plastic materials may also have adverse effects on water quality. Therefore, thick-walled hollow roto-molded water tanks have appeared on the market. Thick-walled hollow roto-molded water tanks adopt roto-molding technology and are made of special plastic mixed materials. The inner wall thickness is moderate, and the center part remains in a cavity state, which can reduce the overall weight of the water tank. Due to the particularity of its materials and processes, this water tank has good pressure resistance and corrosion resistance, and a long service life. The wall thickness of the thick-walled hollow roto-molded water tank is thicker than that of the traditional plastic water tank, but the interior is hollow. The purpose of this is to maintain good stability and avoid instability and deformation after being filled with water.

[0003] The patent with publication number CN215945381U discloses a new type of roto-molded water tank, including a roto-molded water tank body, a through groove, a first groove, a water tank cover and a hinge. A placement rod is arranged on the outside of the roto-molded water tank body, a limiting groove is provided on the roto-molded water tank body, a water tank cover is arranged on the outside of the roto-molded water tank body, a moving rod is arranged on the outside of the water tank cover, a handle is arranged on the outside of the water tank cover, a second groove is provided on the water tank cover, a spring is arranged inside the water tank cover, a connecting rod is arranged on the outside of the roto-molded water tank body, a rubber pad is arranged on the outside of the placement rod, and a hinge is arranged on the outside of the roto-molded water tank body. The new type of roto-molded water tank is provided with a limiting block, through which the water tank cover can be easily installed, and after installation, the moving rod can be moved to facilitate the disassembly of the water tank cover, and a limiting groove is provided, so that the water tank cover is more convenient to install and use.

[0004] In the above-mentioned prior art, when it is necessary to remove the water tank cover, the staff needs to move the two moving rods relative to each other at the same time, so that the two limit blocks are completely moved out of the two limit grooves respectively, and then move the water tank cover upward by the handle to separate the water tank cover from the rotationally molded water tank body. However, this operation requires the cooperation of two people, which is not convenient for a single staff member to operate. In view of this, we propose a thick-walled hollow lightweight rotationally molded water tank. Utility Model Content
