Description

A lifting and heat-insulating cover device Technical Field

[0001] This utility model relates to the field of massage pools and mobile swimming pools, and in particular to a lifting and heat-insulating cover device. Background Technology

[0002] Jacuzzis and portable swimming pools are typically equipped with insulated covers. When not in use, the covers prevent dust, leaves, and rainwater from entering and contaminating the pool water. Furthermore, the insulated covers significantly reduce water evaporation and enhance insulation, thus saving water and electricity. However, because jacuzzis and portable swimming pools are usually quite large, the insulated covers need to be designed to be quite thick to ensure their strength, making them difficult to move. To address this, automatic lifting and lowering mechanisms for the insulated covers have been developed, but these suffer from structural complexity. Summary of the Invention

The operation panel 25 and the lifting control box 22 can be connected via an operation connecting line 251. The operation connecting line 251 is located on the outside of the lifting column assembly. Preferably, the operation connecting line 251 is a spring wire, which can straighten and lengthen when the lifting control box 22 rises and bend and shorten when it descends, preventing the operation line 251 from becoming too long and obstructing operation during descent. The multi-stage telescopic lifting device can use existing multi-stage telescopic lifting devices, specifically those with a screw and rope structure. Multi-stage telescopic lifting devices are existing technology and will not be described in detail here.
