Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 4, the pneumatic rod for a lifting table of the present invention comprises a table board 1, a supporting base 2 and an adjusting mechanism 3 disposed at the lower end of the table board 1. The supporting seat 2 is used for supporting the table board 1, and supporting legs are further arranged at the lower end of the supporting seat 2. The adjusting mechanism 3 is used for changing the height of the pneumatic rod 4 so as to adjust the height of the table board 1.

The support seat 2 is arranged at the lower end of the table board 1, a pneumatic rod 4 is arranged inside the support seat 2, and a pressing handle 5 is arranged on the pneumatic rod 4. The lifting state of the pneumatic rod 4 can be adjusted by adjusting the pressure handle 5.

The adjusting mechanism 3 consists of a hinge rod 6, a rotating rod 7, a rotating disk 8 and a connecting piece 9. The two ends of the hinge rod 6 are hinged with the pressing handle 5. The rotary disk 8 is provided with a spiral part 10, the connecting piece 9 is arranged in the middle of the hinge rod 6, and the connecting piece 9 is provided with an arc-shaped groove 11 matched with the spiral part 10. When the rotary disk 8 is rotated, the connection with the arc-shaped groove 11 can be moved by the spiral part 10. At the lower end of the table 1, there is a guide bar 12, and the guide bar 12 is installed in the middle of the hinge bar 6. When the hinge rod 6 is moved by the connecting piece 9, the guide rod 12 can only make the hinge rod 6 move up and down, thereby limiting the position of the hinge rod 6.

The dwang 7 is installed at the rear end of rotary disk 8, and the dwang 7 is installed at the lower extreme of table 1 through bearing frame 13. The end portion of the turning lever 7 has a through groove 14, the through groove 14 has a driving member 15 therein, the driving member 15 has a strip hole 16 in the middle, and the driving member 15 is mounted on the turning lever 7 by a screw 17 through the strip hole 16.
