[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0021] Example 1
[0022] This invention provides a novel calibration device for a wire mesh tension meter, such as... Figures 1 to 5 As shown, the system includes a frame 1, with bolts 2 threadedly connected to all four sides of the frame 1. A force gauge 3 is mounted on one end of each bolt 2, and an adjusting handwheel 4 is fixedly connected to the other end of each bolt 2. Several rotating wheels 5 are rotatably connected inside the frame 1, with two of the rotating wheels 5 located on either side of each bolt 2. A lead screw 6 is fixedly connected inside each rotating wheel 5. A limit block 7 is rotatably connected to one end of the lead screw 6, and a slider 8 is threadedly connected to the outer surface of the lead screw 6. The slider 8 is slidably connected inside the frame 1.
[0023] like Figure 4 and Figure 5 As shown, the slider 8 is divided into two sections. One section of the slider 8 is rotatably connected to the surface of the lead screw 6, and the other section of the slider 8 is slidably connected to the outer surface of the limiting block 7. When the lead screw 6 is rotated, one end of the slider 8 moves on the surface of the lead screw 6, while the other end slides on the outer surface of the limiting block 7. The limiting block 7 limits the slider 8, thus preventing the slider 8 from moving to the outside of the frame 1 and causing the slider 8 to separate from the frame 1.
[0024] like Figure 4 and Figure 5 As shown, the inner wall of the slider 8 and the outer surface of the limiting block 7 are in contact with each other. When the slider 8 moves, the outer surface is limited by the frame 1, and the inner wall is limited by the limiting block 7, which makes the slider 8 more stable when it moves and avoids the problem of displacement when the slider 8 moves, thereby improving the stability of the slider 8.
[0025] like Figures 2 to 5 As shown, a rack 9 is fixedly connected to the bottom of a single slider 8. A gear 10 is meshed with the surface of the rack 9. A rotating shaft 11 is rotatably connected to both ends of the gear 10. Mounting blocks 12 are fixedly connected to the surfaces of the two rotating shafts 11. The mounting blocks 12 are fixedly connected inside the frame 1. Hexagonal grooves are provided inside the gear 10, the rotating shaft 11, and the mounting blocks 12. A hexagonal bolt 13 is slidably connected inside the hexagonal groove. By installing the hexagonal bolt 13 inside the gear 10, the rotating shaft 11, and the mounting blocks 12, the gear 10 is restricted from rotating by the hexagonal bolt 13, and the movement of the rack 9 and the slider 8 is restricted. This makes the slider 8 locked after movement, avoiding the problem of retraction when the expanded frame 1 is used.
[0026] like Figure 1 and Figure 2As shown, the frame 1 is designed with four sides. Protrusions are provided at both ends of the edge of each side frame 1. The protrusions at both ends of the frame 1 are fixedly connected to the slider 8. When the slider 8 slides inside one of the frames 1, it drives the adjacent frame 1 to move, so that the frame 1 expands as a whole. The slider 8 is limited by one of the frames 1, so that the slider 8 drives the other frame 1 to expand outward more stably.
[0027] like Figure 3 As shown, a rubber pad is attached to the outer surface of a single rotating wheel 5. When the worker moves the rubber pad on the surface of the rotating wheel 5 by hand, the rotating wheel 5 will rotate. This makes the process of the worker moving the rotating wheel 5 more stable and avoids the problem of slippage when the worker moves the rotating wheel 5, thereby improving the stability when the worker moves the rotating wheel 5.
[0028] Working principle: When using this device, the operator clamps and fixes the wire mesh using the wire mesh clamp and rotates the adjusting handwheel 4. The adjusting handwheel 4 drives the bolt 2 to rotate, and the bolt 2 drives the force gauge 3 to move towards the edge of the frame 1. The force gauge 3 drives the wire mesh clamp with the wire mesh installed to move synchronously, and the force gauge 3 tests the wire mesh tension and converts it into a tension value. When the shape of the wire mesh is large, two operators turn the rotating wheels 5 in opposite directions by hand. The rotating wheels 5 drive the corresponding screw 6 to rotate, and the screw 6 drives the slider 8 to move on the surface of the screw 6 and pushes the protrusion to move. The protrusion pushes the corresponding frame 1 to move, so that the frames 1 on both sides expand outward at the same time. The expanded frame 1 can calibrate larger wire meshes, thereby improving the flexibility of the frame 1. This avoids the need to constantly change tension gauges of different sizes to calibrate the wire mesh, thus improving work efficiency.
[0029] When slider 8 slides inside one of the frames 1, it drives rack 9 to move. Rack 9 drives gear 10 to rotate. Gear 10 rotates between two shafts 11. When the worker installs hexagonal bolt 13 inside gear 10, shaft 11 and mounting block 12, gear 10 and shaft 11 are limited by hexagonal bolt 13. Gear 10 and shaft 11 cannot continue to rotate and restricts the movement of rack 9. At this time, slider 8 cannot move, so that slider 8 is locked after movement, avoiding the problem of shrinkage when the expanded frame 1 is used.
[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
