Description

Technical Field

[0001] The utility model belongs to the field of foldable workbenches, in particular to a flip workbench. Background Art

[0002] In the information network cabling practice and competition, the installation, wiring and debugging of each subsystem of building intelligence are designed to strengthen students' engineering capabilities in installation, electrical wiring, debugging, troubleshooting and maintenance of each module of the building intelligent system. It is suitable for the teaching and training of building intelligent equipment installation and operation, property management, and security-related majors. In the process of students' practical training, various tools are needed and applied in the training process or competition. Stacking tools on the training platform will affect the normal training process, progress, and hinder students' operating speed. It is not convenient to use tools placed on the ground or other areas in a timely manner. Moreover, if the parts used in the training process are placed on a flat workbench, it will be difficult for students to see the specifications and models of the parts. If the workbench can be displayed at a certain angle, it will be more convenient for students to use. Utility Model Content

In order to realize the displacement of this group of workbenches, a propulsion assembly is arranged in the support seat, and the screw rod is rotated by the turning handle, and the other end of the screw rod rotates in the screw hole in the movable head, and the upper end of the movable head is connected to the fixed seat. In order to prevent the screw rod from moving back and forth during the rotation of the screw rod, a limit head is arranged on the screw rod, and the through hole on the support seat is located between the limit head and the turning handle, and the limit Due to the limiting effect of the head, the screw can only rotate in a fixed position. The rotation of the screw can drive the movable head to drive the fixed seat to move. Therefore, the workbench on this group of fixed seats can be moved. The two groups of workbenches can be spliced ​​into an integral plane. Even when the relatively fixed workbench is placed flat, the movable workbench can be adjusted to a specific angle, and the movable workbench can be moved to one end through the propulsion component to abut against the relatively fixed workbench, forming a combined workbench with one side flat and the other side angled. It is suitable for different students to change different forms according to their habits during practical training to meet their usage needs.
