and the motion part still has the transmission of adopting lead screw and complicated rhombus extension subassembly, and stability is difficult to control, and the structure is complicated moreover, makes whole desk heavy, and the installation is dismantled inconveniently, and more importantly children experience is relatively poor, can't in time adjust to suitable angle.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a parallel elevating system, its specific scheme is as follows:
a parallel lifting mechanism comprises a cross shaft bracket, mounting seats are arranged at two ends of the cross shaft bracket, an upper arm and a forearm are mounted on the mounting seats, the upper arm and the forearm are connected by a joint structure, wherein,
a first cylinder is arranged in the upper arm; a second cylinder is arranged in the front arm; a pair of connecting discs is arranged in the joint structure; a plurality of guide posts are arranged between the pair of connecting discs, and the two guide posts are respectively fixedly connected with the pair of connecting discs;
the fixed end of the first cylinder is hinged with the mounting seat, and the telescopic end of the first cylinder is connected to the guide pillar;
the telescopic end of the second cylinder is hinged to the guide pillar, the fixed end of the second cylinder is connected with the desktop, and the first cylinder and the second cylinder are connected to different guide pillars to form a parallel lifting mechanism.
Furthermore, the number of the guide columns is three, and the guide columns are uniformly distributed by taking the circle center of the connecting disc as the center.
Furthermore, the connecting line of the connecting points of the guide post and the connecting disc is in an equilateral triangle shape.
The utility model has the advantages of that:
the utility model discloses a double cylinder design in upper arm and the forearm, the cylinder and the articulated design of guide pillar, the position selection design of guide pillar, the quick adjustment desktop displacement of being convenient for carries out position adjustment when realizing the desktop height control, reaches the lift effect of parallel four sides form.
