Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The bar bending angle measuring tool shown in fig. 1 to 7 includes a bottom plate 1, a telescopic plate 2, two fixed columns 3 and a movable column 4 having the same diameter as the fixed columns 3.
The base plate 1 is provided with feet 16, which feet 16 are used to support the base plate 1. The bottom plate is provided with circular arc-shaped measuring groove 5, the central angle of measuring groove 5 is 90 degrees in this embodiment, and measuring groove 5 is a through groove. The movable column 4 is slidably connected in the measuring tank 5 and extends upward above the base plate 1. The two fixed posts 3 and the movable post 4 have the same diameter. The fixed column 3 is connected above the bottom plate 1. The expansion plate 2 is arranged on one side of the two fixing columns 3 and is parallel to the circular connecting lines of the two fixing columns 3. And fixing the bent bar 17 between the fixed column and the expansion plate. One of the fixed columns 3 is arranged at the center of the measuring groove 5.
In order to facilitate the sliding of the movable column 4, a connecting rod 6 is also provided. The connecting rod 6 is arranged below the bottom plate, one end of the connecting rod 6 is rotatably connected to the circle center of the measuring groove 5, the other end of the connecting rod extends towards the measuring groove 5, and a connecting column 7 is upwards arranged. The connecting column 7 penetrates through the measuring groove 5 and is arranged above the bottom plate 1 to be sleeved and connected with the movable column 4.
