[0023] The utility model provides a fixing device for a differential scanning calorimeter that is easy to disassemble through improvement. The technical solution of the utility model is:

[0024] like Figures 1 to 3As shown, a fixing device for a differential scanning calorimeter that is easy to disassemble includes a mounting base 1 and a differential scanning calorimeter 2. The mounting base 1 is provided with a placement groove 3, which is a groove with a rectangular structure. The differential scanning calorimeter 2 is located inside the placement groove 3. The differential scanning calorimeter 2 is movably installed inside the mounting base 1 through the placement groove 3. The mounting base 1 is provided with a fixing mechanism, which includes two movable grooves 4, a fixing block 5, a spring 6 and a fixing groove 7. The movable groove 4 is a groove with a rectangular structure. The two movable grooves 4 are symmetrically arranged on the inner wall of the placement groove 3. The fixing block 5 is an "L"-shaped block. The two fixing blocks 5 are movably installed inside the two movable grooves 4 respectively, and the side wall surface of the two fixing blocks 5 corresponding to the differential scanning calorimeter 2 is an inclined surface. The two springs 6 are movably mounted in the two movable grooves 4 and fixedly connected with the two fixed blocks 5. The fixed grooves 7 are rectangular grooves. The two fixed grooves 7 are respectively opened at the positions corresponding to the two fixed blocks 5 on the differential scanning calorimeter 2. The differential scanning calorimeter 2 can be fixed on the mounting seat 1 through the fixing mechanism. When installing, the differential scanning calorimeter 2 is placed in the placement groove 3. Since the fixed block 5 has an inclined surface, the fixed block 5 will move toward the inside of the movable groove 4 and press the spring 6 after being squeezed by the differential scanning calorimeter 2. When the differential scanning calorimeter 2 stops moving, the fixed block 5 will move to the inside of the fixed groove 7 under the action of the spring 6, so that the differential scanning calorimeter 2 is fixed in the placement groove 3. The mounting seat 1 is provided with a disassembly mechanism;

[0025] like Figure 2 and Figure 3As shown, the disassembly mechanism includes a transmission groove 8, an extrusion block 9, a connecting plate 10 and a transmission bolt 11. The transmission groove 8 is a groove of a rectangular structure. The transmission groove 8 is arranged at the lower part of the interior of the mounting seat 1. The transmission groove 8 is connected to the interior of the spring 6. The extrusion block 9 is a block of a trapezoidal structure. There are two extrusion blocks 9. The two extrusion blocks 9 are movably installed in the transmission groove 8 at positions corresponding to the two fixed blocks 5. The wall surface of one side of the extrusion block 9 corresponding to the fixed block 5 is an inclined surface, and the wall surface of the fixed block 5 corresponding to the extrusion block 9 is an arc surface. The connecting plate 10 is a plate of a rectangular structure. The connecting plate 10 is arranged at the lower part of the transmission groove 8. The connecting plate 10 and the extrusion block 9 are fixedly connected. The transmission bolt 11 is movably installed on the bottom wall of the mounting seat 1. The bolt 11 penetrates upwardly through the upper and lower wall surfaces of the connecting plate 10 and is threadedly connected with the connecting plate 10. Through the setting of the disassembly mechanism, when the differential scanning calorimeter 2 needs to be disassembled from the mounting base 1, the transmission bolt 11 can be rotated, and the transmission bolt 11 is threadedly connected to the connecting plate 10. The connecting plate 10 will drive the extrusion block 9 to move upward inside the transmission groove 8. The upward movement of the extrusion block 9 will squeeze the fixed block 5. Since the extrusion block 9 has an inclined surface, the fixed block 5 will leave the inside of the fixed groove 7 and return to the inside of the movable groove 4 after being squeezed by the extrusion block 9. At this time, the differential scanning calorimeter 2 will not be fixed by the fixed block 5, and the differential scanning calorimeter 2 can be disassembled from the mounting base 1, thereby achieving the effect of easy disassembly.

[0026] like Figure 1 and Figure 4 As shown, in one embodiment, a base 12 is provided below the mounting seat 1, and four supporting legs 13 are fixedly installed on the top of the base 12. The tops of the supporting legs 13 are fixedly connected to the mounting seat 1, and the base 12 and the supporting legs 13 can support the mounting seat 1;

[0027] A first mounting groove 14 is provided in the middle of the bottom wall of the base 12. The first mounting groove 14 is a rectangular groove. A hydraulic rod 15 is fixedly installed on the upper part of the first mounting groove 14. A support plate 16 is fixedly installed on the output end of the hydraulic rod 15. The support plate 16 is a rectangular plate. An anti-slip bottom pad 22 is fixedly installed on the bottom of the support plate 16.

[0028] A plurality of second mounting grooves 17 are provided around the bottom wall of the base 12. The second mounting grooves 17 are rectangular grooves. A roller seat 18 is movably installed inside the second mounting groove 17. The roller seat 18 is a rectangular structure. A rotatable roller 19 is movably installed inside the roller seat 18. The roller 19 is a cylindrical structure. A motor 20 is installed at a position corresponding to the roller seat 18 inside the mounting base 1. A drive shaft 21 is fixedly installed on the output end of the motor 20. The drive shaft 21 is a cylindrical structure. The drive shaft 21 penetrates downward through the wall of the roller seat 18 and is threadedly connected to the roller seat 18. Through the setting of the hydraulic rod 15, when the device needs to be moved, the hydraulic rod 15 can be started, and the hydraulic rod 15 drives the support plate 16 to move downward. , and then the base 12 can be lifted from the ground, and the motor 20 is started at this time. The motor 20 drives the drive shaft 21 to rotate, and the drive shaft 21 is threadedly connected to the roller seat 18. The roller seat 18 will drive the roller 19 to move downward inside the second mounting groove 17. When the roller 19 contacts the ground, the hydraulic rod 15 will drive the support plate 16 back to the inside of the first mounting groove 14. At this time, the device can be moved by the roller 19. After the movement is completed, the hydraulic rod 15 can be started again to make the support plate 16 contact the ground, and then the motor 20 is started to retract the roller 19 into the second mounting groove 17. Finally, the hydraulic rod 15 is started to retract the support plate 16, which not only facilitates the movement of the device, but also improves the stability of the device.

[0029] The specific working methods are:

[0030] By providing a fixing mechanism, during installation, the differential scanning calorimeter 2 is placed in the placement groove 3. Since the fixing block 5 has an inclined surface, the fixing block 5 will move toward the inside of the movable groove 4 and squeeze the spring 6 after being squeezed by the differential scanning calorimeter 2. When the differential scanning calorimeter 2 stops moving, the fixing block 5 will move to the inside of the fixing groove 7 under the action of the spring 6, so that the differential scanning calorimeter 2 is fixed in the placement groove 3. At the same time, a disassembly mechanism is provided. When it is necessary to disassemble the differential scanning calorimeter 2 from the mounting seat 1, the transmission bolt 11 can be rotated. The transmission bolt 11 is threadedly connected to the connecting plate 10, and the connecting plate 10 will drive the squeezing block 9 to move upward in the transmission groove 8. The squeezing block 9 moves upward and squeezes the fixing block 5. Since the squeezing block 9 has an inclined surface, the fixing block 5 will leave the inside of the fixing groove 7 and return to the inside of the movable groove 4 after being squeezed by the squeezing block 9. At this time, the differential scanning calorimeter 2 will not be fixed by the fixing block 5, and the differential scanning calorimeter 2 can be disassembled from the mounting seat 1.
