Description

TECHNICAL FIELD

[0001] The utility model is suitable for the field of cosmetic or home display cabinet, especially for the small lifting structure of the counter top. BACKGROUND

[0002] In today's era, the decoration industry is booming, showing a trend of change with each passing day. Customers' requirements for product surface integrity are increasingly stringent, and they require not only aesthetics but also hidden automation. As a result, future decorative products are increasingly becoming more sophisticated and automated.

[0003] In the field of display cabinet design in high-end shopping malls and luxury goods industries, more and more lifting mirrors have become a trend. However, this design trend has brought many unavoidable problems to the production and on-site assembly of enterprises. Chinese patent "folding bed makeup table" (ZL2022221725881) realizes the lifting of the makeup table and the mirror through the connection of the table leg and the lifting structure, although the makeup table occupies a small area and is suitable for bed office, but since the table is connected by a single table leg, the mirror will shake at different amplitudes when lifting, thereby affecting the use effect of the makeup table. To ensure the stability of the mirror, the lifting structure generally uses a sliding limiting mechanism. Chinese patent "dressing table with liftable mirror" (ZL2023231663265) starts the electric push rod, the electric push rod drives the bracket to move, the bracket drives the mirror to move, and the bracket drives the stabilizing plate and the limiting rod to slide on the surface of the stabilizing rod and the inner cavity of the limiting block, respectively, but the lifting structure is relatively complex, requires a bracket and two electric push rods, and the limiting sliding uses contact sliding between surfaces, which is easily blocked.
