DETAILED DESCRIPTION

[0022] The utility model discloses a convenient to replace's scale body mounting device, the technical scheme of the utility model is:

[0023] The utility model discloses a convenient to replace's scale body mounting device, the technical scheme of the utility model is:

[0024] As Figures 1-4 The utility model discloses a convenient to replace's scale body mounting device, the technical scheme of the utility model is:

[0025] Further, as Figure 2 And Figure 3 The utility model discloses a convenient to replace's scale body mounting device, the technical scheme of the utility model is:

[0026] Further, as Figures 2-4 The utility model discloses a convenient to replace's scale body mounting device, the technical scheme of the utility model is:

[0027] Further, as Figures 2-4 The utility model discloses a convenient to replace's scale body mounting device, the technical scheme of the utility model is:

[0028] Furthermore, such as Figures 2-4 As shown, the connecting plate 2 has two grooves 16, and the two half-threaded bolts 6 have two sliding grooves 17 respectively. Two limiting rods 18 are slidably connected in the two grooves 16 respectively. The width of the limiting rods 18 is the same as the width of the sliding grooves 17. The two limiting rods 18 are symmetrical about the fixing block 11 and pass through the two sliding grooves 17 respectively.

[0029] Furthermore, such as Figure 4 As shown, four limiting plates 19 are fixedly connected to the two limiting rods 18 respectively, and four springs 20 are fixedly connected to the four limiting plates 19 respectively. The two adjacent limiting plates 19 are symmetrical about the limiting rods 18, and the four springs 20 are fixedly connected to the two grooves 16 respectively.

[0030] The specific working method is as follows: When installing the device, first insert the fixing block 11 into the slot 10. The slot 12 is pushed into the fixing block 11 by the mounting plate 3. After the fixing block 11 is fully embedded in the slot 10, the slot 12 is reset under the action of the spring 15 and embedded in the slot 10, thus completing the fixing of the connecting plate 2 and the mounting plate 3. At this time, pull the limiting rod 18 so that the limiting rod 18 moves towards the spring 20 and away from the through hole 4. Set the spring washer 8 and the flat washer 9 onto the half-threaded bolt 6. Then insert the half-threaded bolt 6 into the through hole 4 and the through hole 5. Release the limiting rod 18 so that the limiting rod 18 moves towards the through hole 4. Rotate the half-threaded bolt 6 so that the sliding groove 17 and the limiting rod 18 are in the same vertical position. On the surface, the limiting rod 18 then passes through the slide groove 17, preventing the half-threaded bolt 6 from rotating. At this time, the nut 7 can be threadedly connected to the half-threaded bolt 6. Rotating the nut 7 causes it to move downwards. When the bottom of the nut 7 is in contact with the top of the mounting plate 3, continue rotating the nut 7, and the half-threaded bolt 6 will move upwards, clamping and fixing the connecting plate 2 and the mounting plate 3. When the half-threaded bolt 6 breaks, the root of the half-threaded bolt 6 will not fall into the through hole 4 or through hole 5 due to the action of the nut 7. The root can be removed from through hole 5. At this time, the limiting rod 18 can be pulled to release the restriction on the half-threaded bolt 6. The half-threaded bolt 6 falls with its own weight, and the broken half-threaded bolt 6 can be easily removed. A new half-threaded bolt 6 can then be replaced.

[0031] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Any matters not covered in this utility model are common knowledge to those skilled in the art.
