Description

Technical Field

[0001] The utility model relates to the technical field of calorimeters, in particular to an adiabatic accelerating calorimeter. Background Art

[0002] A calorimeter is a thermal analyzer that is mainly used to measure the heat generated by chemical substances during storage and release, as well as the heat release rate. The sample to be tested is placed in the calorimetric chamber, and then the calorimeter is heated. The temperature difference between the sample and the surrounding area is then compared and adjusted to a state of equilibrium with the sample to achieve the insulation function.

[0003] Current tests basically place samples directly in the calorimetric chamber, but there is no relative limiting structure. This causes the samples to topple over during processing due to machine vibration or impact, which directly affects the efficiency and safety of the test. For this purpose, an adiabatic accelerating calorimeter is established. Utility Model Content

[0005] As an optimal technical solution of the utility model, a bottom groove is set in the calorimetric chamber and below the placement plate, and the side walls of the bottom groove are rotatably connected to two rotating shafts. One end of the linkage rod extends into the bottom groove and is fixedly connected to one side wall of the rotating shaft. An active rod is fixedly connected to the side wall of the rotating shaft away from the linkage rod, and a connecting column is rotatably connected to the top edge of the active rod away from one end of the rotating shaft. The connecting column is rotatably connected to a pressing plate through its top end, and a telescopic stud is fixedly connected to the bottom side wall of the pressing plate. The bottom end of the telescopic stud is telescopically inserted and connected in the middle of the bottom side wall of the calorimetric chamber.

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] Please refer to Figure 1-3The utility model discloses an adiabatic accelerating calorimeter, comprising a calorimetric chamber 1, wherein a vertical plate 2 is fixedly connected to the bottom of the calorimetric chamber 1 and near both side edges, a placement plate 5 is fixedly connected to the inner wall of the calorimetric chamber 1 near the bottom, and movable grooves 6 are provided through the placement plate 5 near both side edges thereof, and a linkage rod 9 is movably connected in the movable groove 6, and the linkage rod 9 is an arc-shaped structure, and one end of the linkage rod 9 is fixedly connected to a docking plate 17, and both ends of the docking plate 17 away from the linkage rod 9 are rotatably connected to a rotating shaft 18, and one side of the rotating shaft 18 is fixedly connected to a clamping plate 16, and the clamping plate 16 is an arc-shaped structure, and a side wall of the clamping plate 16 away from the rotating shaft 18 is fixedly connected to a slide pad 19;

[0015] An installation box 3 is fixedly connected to the outer wall of the bottom of the calorimetric chamber 1 and on the side wall on one side of the telescopic stud 4. A motor 14 is detachably connected to the installation box 3. A driving gear 15 is fixedly connected to the output end of the motor 14. A driven gear 13 is meshedly connected to one side of the driving gear 15. The driven gear 13 is rotatably connected to the middle of the bottom side wall of the calorimetric chamber 1. A screw hole is opened in the middle of the driven gear 13, and the driven gear 13 is threadedly sleeved on the telescopic stud 4 through the screw hole.

[0016] The technical effect of this solution is that the sample is placed on the placement plate 5. After the placement is completed, the motor 14 installed in the installation box 3 is started to drive the driving gear 15 to rotate, and the driving gear 15 drives the driven gear 13 to rotate synchronously through the meshing connection. Because the driven gear 13 and the telescopic stud 4 are in a threaded connection, the rotation of the driven gear 13 can drive the telescopic stud 4 to rise and fall synchronously. As the telescopic stud 4 drives the pressing plate 12 and the connecting column 11 to descend synchronously, one end of the active rod 10 is pressed down, and the linkage rod 9 is driven to move through the rotating shaft 8 to drive the clamping plate 16 to clamp the sample, thereby ensuring the stability of the sample placement and avoiding the sample from tipping over during the test, which may cause inaccurate test data and safety problems.

[0017] A bottom groove 7 is provided in the calorimetric chamber 1 and below the placement plate 5. The side walls of the bottom groove 7 are rotatably connected to two rotating shafts 8. One end of a linkage rod 9 extends into the bottom groove 7 and is fixedly connected to one side wall of the rotating shaft 8. An active rod 10 is fixedly connected to the side wall of the rotating shaft 8 away from the linkage rod 9. A connecting column 11 is rotatably connected to the top edge of one end of the active rod 10 away from the rotating shaft 8. The connecting column 11 is rotatably connected to a pressing plate 12 through its top end. A telescopic stud 4 is fixedly connected to the bottom side wall of the pressing plate 12. The bottom end of the telescopic stud 4 is telescopically inserted and connected in the middle of the bottom side wall of the calorimetric chamber 1.

[0018] The technical effect of this solution is that the clamping plate 16 is connected to the docking plate 17 through the rotating shaft 8 of the calorimetric chamber 1, and every two clamping plates 16 form a pair. When the clamping plate 16 contacts the sample, it will rotate along the rotating shaft 8 of the calorimetric chamber 1, so that the clamping plate 16 can adapt itself to fit tightly on the outer wall of the sample, and because it can rotate, it can also clamp samples of different sizes, effectively improving the flexibility and practicality of the equipment application.

[0019] Specifically, when the utility model is used, a rubber pad is embedded and fixed in the middle of the top side wall of the placement plate 5 for placement and sliding, so as to increase the friction. When the telescopic stud 4 drives the pressing plate 12 to descend, it can drive the two connecting columns 11 to descend synchronously, and as the connecting column 11 goes down, one end of the active rod 10 can be pressed down. To ensure the smoothness of the movement, as the active rod 10 goes down, it will also drive the connecting column 11 to rotate and tilt synchronously, thereby avoiding movement interference. To ensure the stability of the clamping plate 16 on the sample, a sliding pad 19 is fixed on one side of the clamping plate 16. When the clamping plate 16 clamps the sample, the sliding pad 19 can increase the friction between the clamping plate 16 and the sample, thereby improving the clamping effect. Because it is driven by the motor 14, the efficiency of the operation can be improved. The lifting and lowering activities of the telescopic stud 4 can be adjusted as needed, and the tightness of the clamping of the sample by the clamping plate 16 can be adjusted, which can be flexibly adjusted according to the properties of the sample.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
