Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an embodiment of the present invention provides a technical solution: the utility model provides a lifting table, includes four heel posts 1, the holding tank has been seted up to 1 undercut in heel post top, the holding tank content is equipped with

table leg

2, 2 tops of table leg are provided with desktop 3, be provided with bearing frame 4 between the

heel post

1, 4 left and right ends symmetries of bearing frame are provided with left lifting means and right lifting means, left side lifting means is the same with right lifting means structure, 4 centers in bearing frame are provided with actuating mechanism, actuating mechanism is used for synchronous drive lifting means to drive 3 upshifts of desktop.

In this embodiment, left side lifting unit is including two positioning seats 5 that set up side by side around, be provided with dwang 6 between positioning seat 5 of left side lifting unit and the positioning seat 5 of right side lifting unit, 6 both ends of dwang are all run through the positioning seat 5 that corresponds one side and are articulated to have rocking arm 7, rocking arm 7 is articulated with table leg 2.
