Description

Technical Field

[0001] The utility model relates to the field of test tube brackets, in particular to a bracket. Background Art

[0002] Adiabatic calorimeter is a device used to measure the thermal stability of chemicals. The chemical to be tested is placed in the test cell of the adiabatic calorimeter, and the test cell containing the chemical is placed in a heating furnace. The chemical is heated by the heating furnace, and the temperature of the test cell is monitored by a temperature sensor. When the temperature sensor monitors that the temperature of the test cell is different from the temperature provided by the heating furnace, it can be determined that the chemical has undergone thermal decomposition at this temperature, thereby determining the thermal stability of the chemical.

[0003] The test pool of the adiabatic calorimeter includes a sample loading ball, a sample loading tube and a sample loading port. One end of the sample loading tube is connected to the sample loading ball, and the other end of the sample loading tube is connected to the sample loading port. The sample loading ball is used to load the chemical to be tested. The volume of the sample loading ball is 8-10 ml, and the diameter of the sample loading port is 1-4 mm. The chemical to be tested enters the sample loading ball through the sample loading port and the sample loading tube. However, since the sample loading ball is spherical, the sample loading ball itself cannot stand stably to ensure that the sample loading port is vertically upward, and a person needs to hold the test pool by hand to load the sample, which is very inconvenient to operate, and the hand may shake during the operation, causing the chemical to be tested to leak out, thereby polluting the environment. A bracket that can fix the sample loading ball and is easy to install is now provided. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a bracket.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A bracket comprises a bracket, the bracket is in a hollow cone shape, an opening is formed on the side of the bracket, an opening is formed on the top of the bracket, the inner side of the opening is connected to the opening, the bottom of the bracket has a supporting surface, and the bracket supports a test pool;

[0007] The test pool comprises a sample loading tube which is arranged at the opening and coaxial with the opening, one end of the sample loading tube located inside the bracket is fixedly connected with a sample loading ball, and the other end of the sample loading tube is connected with a sample loading port.

[0008] Furthermore, the width of the opening gradually decreases from the outside to the inside, the width of the outermost side of the opening is greater than the outer diameter of the sample tube, the width of the innermost side of the opening is less than the outer diameter of the sample tube, and the aperture of the opening is greater than the outer diameter of the sample tube.

[0009] Furthermore, the outermost width of the opening is 0.01-1.5 mm larger than the outer diameter of the sample tube, and the width of the opening is 1-7 mm.

[0010] Furthermore, a mounting groove is provided at the top of the inner wall of the bracket, a limiting groove is provided at the top of the mounting groove, an incomplete tooth ring is rotatably connected to the mounting groove, a limiting convex ring is provided at the top of the incomplete tooth ring, and the limiting convex ring is rotatably connected to the limiting groove.

[0011] Furthermore, a sliding rod is slidably connected to the side wall of the bracket near the top, a second protrusion is provided at the bottom end of the sliding rod, a first protrusion is provided at the side end of the incomplete tooth ring, the first protrusion is snap-connected with the second protrusion, and a spring is sleeved on the sliding rod.

[0012] Furthermore, a rotating shaft is rotatably connected to the top of the bracket, a driving gear is provided at the bottom of the rotating shaft, the driving gear is meshed and connected with the incomplete gear ring, a rotating handle is provided at the top of the rotating shaft, and a torsion spring is sleeved on the rotating shaft.

[0013] Beneficial effects of the utility model:

[0014] 1. First, place the sample ball of the test pool into the hollow part of the bracket. Since the width of the outermost side of the opening is larger than the outer diameter of the sample tube, the width of the opening gradually decreases from the outside to the inside. The sample tube of the test pool can be pushed into the inside of the opening from the outside to the inside. Since the width of the innermost side of the opening is smaller than the outer diameter of the sample tube, a certain external force is required to clamp the sample tube into the opening. Since the aperture of the opening is larger than the outer diameter of the sample tube, the sample tube can be clamped into the opening, so that the chemical to be tested can be conveniently loaded into the test pool.

[0015] 2. The incomplete toothed ring can be driven to rotate by meshing the driving gear with the incomplete toothed ring, and the inner wall of the incomplete toothed ring is pressed against the sample tube. When the incomplete toothed ring rotates a certain angle, the inclined surface of the first protrusion pushes the second protrusion to move the sliding rod. Then, under the reset action of the spring, the first protrusion is engaged with the second protrusion. Through the reset action of the torsion spring and the spring, the first protrusion is clamped with the second protrusion, and the inner wall of the incomplete toothed ring is pressed against the sample tube to fix it, which can prevent the sample tube from falling off due to external force or improper operation.

Since the innermost width of the opening 11 is smaller than the outer diameter of the sample tube 22, a certain external force is required to clamp the sample tube 22 into the opening 12.

When the incomplete toothed ring 3 rotates a certain angle, the inclined surface of the first protrusion 312 pushes the second protrusion 321 to move the sliding rod 32. Subsequently, under the resetting action of the spring 323, the first protrusion 312 is engaged and connected with the second protrusion 321, and the inner wall of the incomplete toothed ring 3 is pressed against the sample loading tube 22 to fix it, which can prevent the sample loading tube 22 from falling off due to external force or improper operation.
