[0028] like Figure 1 to Figure 3 As shown, this embodiment proposes a hardness measuring device, including a workbench 1, a fixed plate 2 is fixedly connected to the top of the workbench 1, a fixed column 3 is fixedly connected to the top of the fixed plate 2, a top plate is fixedly connected to the top of the fixed column 3, a cylinder 4 is fixedly connected to the top of the top plate, a sliding column 5 is slidably connected inside the cylinder 4, a pressure detection head 6 is fixedly connected to the bottom of the sliding column 5, a bottom plate 7 is fixedly connected to one side of the top of the workbench 1, four columns 8 are fixedly connected to the top of the bottom plate 7, a connecting plate 9 is fixedly connected to the top of the four columns 8, vertical plates 10 are fixedly connected to both sides of the top of the connecting plate 9, and the two vertical plates 10 are connected internally by bearings There is a threaded rod 11, and the threads on both sides of the outside of the threaded rod 11 are in opposite directions. Threaded blocks 12 are connected to the outside of the threaded rod 11 through threads. The bottoms of the two threaded blocks 12 are fixedly connected to limit rods 13. Gears 14 are fixedly connected to both sides of the outside of the threaded rod 11. Racks 15 are provided at the bottom of the two gears 14. The gears 14 and the racks 15 are meshed. One side of the two racks 15 is fixedly connected to a pull rod 17, one side of the two threaded blocks 12 is fixedly connected to a moving rod 18, one end of the two moving rods 18 is fixedly connected to a moving plate 19, and one side of one of the moving plates 19 is fixedly connected to a clamping plate 20.

[0029] In this embodiment, the sliding column 5 passes through one side of the interior of the top plate, and the outer surface of the sliding column 5 is in contact with the interior of the top plate, which can facilitate the sliding operation of the sliding column 5 .

[0030] In this embodiment, the two vertical plates 10 are symmetrically distributed, and limiting grooves are provided on both sides of the top of the connecting plate 9 to facilitate subsequent limiting work.

[0031] In this embodiment, the two limiting rods 13 extend into the two limiting grooves respectively, and the outer surfaces of the two limiting rods 13 are in contact with the insides of the two limiting grooves respectively, which can facilitate the limiting work of the limiting rods 13 on the threaded block 12.

[0032] In this embodiment, a sliding block 16 is fixedly connected to one side of the bottom of the rack 15 , and sliding grooves are provided on both sides of the top of the connecting plate 9 , so that the rack 15 can drive the sliding block 16 to slide.

[0033] In this embodiment, the two sliding blocks 16 are respectively slidably connected to the inside of the two sliding grooves, and the two pull rods 17 are both set to be L-shaped, which can facilitate the staff to pull the pull rods 17.

[0034] In this embodiment, the two threaded blocks 12 are symmetrically distributed, and the sliding groove and the limiting groove are respectively located on two sides of the outside of the vertical plate 10.

[0035] In this embodiment, the two movable plates 19 are both set to be H-shaped, and the bottoms of the two movable plates 19 are respectively in contact with the two sides of the top of the connecting plate 9, which can facilitate the movement of the movable plates 19.

[0036] During use, when it is necessary to measure the hardness of the housing material, the staff first needs to place the material on the top of the connecting plate 9, and then the staff pulls the pull rod 17. The pull rod 17 will synchronously drive the rack 15 and the sliding block 16 to move during the movement. The rack 15 will synchronously drive the gear 14 to rotate during the movement. The gear 14 will synchronously drive the threaded rod 11 to rotate during the rotation. The threaded rod 11 will synchronously drive the threaded blocks 12 on both sides to move toward the middle during the rotation. During this process, the limit rod 13 will limit the threaded block 12. During the movement, block 12 will synchronously drive moving rod 18 to move, and moving rod 18 will synchronously drive moving plate 19 to move, and moving plate 19 will synchronously drive clamping plate 20 to move. When the distance between clamping plate 20 and another moving plate 19 is sufficient to hold the material of the house, the material will be clamped, thereby ensuring the fixation of materials of different shapes. Then the staff stops pulling pull rod 17 and opens oil cylinder 4. After opening, oil cylinder 4 will control sliding column 5 to slide downward, and sliding column 5 will synchronously drive pressure detection head 6 to measure the hardness of the house material during the sliding process.

[0037] Example 2

[0038] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the bottom of the splint 20 is in contact with one side of the top of the connecting plate 9, and a brush 21 is fixedly connected to the bottom of one of the movable plates 19, which can facilitate the splint 20 to clamp the material and the brush 21 to clean the residue.

[0039] In this embodiment, the clamping plate 20 and the brush 21 are in the same plane, and the bottom of the brush 21 is in contact with one side of the top of the connecting plate 9, which can facilitate the coordinated use between the clamping plate 20 and the brush 21.

[0040] During use, after the hardness measurement is completed, the staff needs to push the pull rod 17 in the opposite direction for a certain distance to take out the house material, and then push the pull rod 17 again. During the movement, the pull rod 17 will again move the rack 15 and rotate the gear 14. During the rotation, the gear 14 will synchronously drive the threaded rod 11 to rotate. During the rotation, the threaded rod 11 will synchronously drive the threaded block 12 to move. During the movement, the threaded block 12 will synchronously drive the moving rod 18 and the moving plate 19 to move. Then the splint 20 will push the residue on the top of the connecting plate 9 toward the moving brush 21. When the splint 20 and the residue have slid through the inside of the brush 21, the pull rod 17 is pulled in the opposite direction, and then the splints 20 on both sides will expand outwards. At this time, the brush 21 will clean up the excess residue, so that it is convenient to collect the residue.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
