Description

Technical Field

[0001] The utility model relates to a retaining frame for a lifting table, a lifting table leg and a lifting table, and belongs to the technical field of lifting tables. Background Art

[0002] At present, lifting tables have increasingly entered into daily production and life. Lifting table legs are the main components for realizing the lifting and adjustment of the lifting table top. The rolling components composed of rolling friction are easier to reduce resistance than sliding friction components, so they are increasingly used in the lifting system of the table legs of lifting tables. In addition, customer requirements vary greatly, and various demands for various usage scenarios and aesthetic requirements emerge in an endless stream. At present, lifting table legs use various sizes of rectangular tubes and pipe fittings with special cross-section shapes, such as triangles, pentagons and other special-shaped pipe fittings; the gap size of the sliding inner and outer sleeves of the lifting table legs required by each customer is also different. At the same time, the manufacturing size tolerances of the table leg pipe fittings of each manufacturer and each batch during the production process are different. Therefore, in order to adapt to the lifting table products composed of sliding inner and outer sleeve pipe fittings of lifting table legs with various cross-sectional shapes.

[0003] The Chinese utility model patent with authorization announcement number CN210034171U discloses a retainer, including two side plate assemblies arranged opposite to each other, the two side plate assemblies are detachably connected, the side plate assemblies are hinged by a first side plate and a second side plate, the upper ends of the first and second side plates are provided with a first rolling group, the lower ends of the first and second side plates are provided with a second rolling group, the first rolling group and the second rolling group each include a waist-shaped annular groove arranged on the left and the right, and a plurality of balls are evenly distributed in the waist-shaped annular groove. If the ball retainer for the lifting table with authorization announcement number CN210034171U is used, the factory must develop and store the corresponding cross-sectional shape of the sliding inner and outer sleeves of the lifting table legs Ball retainers for pipe fittings, each cross-sectional shape of pipe fittings must develop ball retainers for pipe fittings with the cross-sectional shape of the sliding inner and outer sleeves of the lifting table legs, and each cross-sectional size of pipe fittings must develop corresponding different series of ball retainers. At the same time, in order to adapt to the different gap sizes of the sliding inner and outer sleeves of the lifting table required by each customer and the different manufacturing size tolerances of the table leg pipe fittings of each manufacturer and each batch, it is necessary to develop ball retainers of the same series but different sizes. The wide variety and complex sizes of ball retainers bring great troubles to the factory's warehouse storage, distribution and correct production of the production line. At the same time, mold development, semi-finished product manufacturing and storage consume a lot of space, huge expenses, and high costs. Summary of the invention
