Detailed ways

The installation tool for the SF6 gas-taking joint of the utility model is composed of a torque rod part 1, a tool execution body part 2, and a torque arm 3 connected in sequence, wherein:

The torque rod part 1 is mainly composed of a hexagonal column 4 with a threaded rod and a torque rotation hole 5, which drives the tool to perform the clockwise or counterclockwise rotation of the main body part 2 and the torque arm 3.

The implement body part 2 of the tool is mainly composed of an adjusting nut 6 , a moment arm pin 7 and a support spring 8 . The main function of this part is to achieve the effect of adjusting the radial diameter of the torque arm 3 through the different rotation modes of the adjusting nut 6 on the thread of the torque rod 1. The torque spring 8 is used to give the torque arm a radial force when the adjusting nut 6 is adjusted. The thrust in the direction makes it easy to operate the adjustment of the adjustment nut 6, and the moment arm pin 7 is the fulcrum to facilitate the radial movement of the moment arm 3.

The moment arm 3 is mainly composed of the main moment arm 3a, the extension moment arm 9, the transmission pin 10 and the movable grasping block 11. The extension moment arm 9 is inserted into the rectangular box where the SF6 gas intake port is located when in use, and the torque is adjusted by the adjustment nut 6. Under the adjustment of the arm 3, the movable grasping block 11 on the extended moment arm 9 and its rotating pin 10 cooperate to firmly grasp the air-taking joint screw, and apply force to the joint screw under the drive of the torque rod 1 so as to realize the installation and tightening of the joint screw. Fixing and loosening and dismantling.

Further, in the installation tool, by adding the hexagonal column 4 and the torque rotation hole 5 at the moment bar 1, the tool can not only be operated with a simple tool such as a screwdriver, but also can be operated with a ratchet wrench, a socket wrench, etc. It can be operated with a portable electric hand drill, and even a torque wrench can be used to quantify the torque when there is a torque requirement for the joint screw.

The utility model is composed of a moment bar part 1, a tool executive body part 2 and a moment arm part 3 connected in sequence. Its working principle:

1) The torque rod part 1 is mainly composed of a threaded hexagonal square column 4 and a torque rotation hole 5.
