Description

Technical Field

[0002] Low temperature constant temperature water bath is widely used in research departments such as petroleum, chemical industry, electronic instrumentation, physics, chemistry, bioengineering, medicine and health, life science, light industry and food, physical property testing and chemical analysis, colleges and universities, enterprise quality inspection and production departments. It provides users with a field source with controlled heat and cold and uniform and constant temperature when working, and can perform constant temperature tests or tests on test samples or products. It can also be used as a heat source or cold source for direct heating or cooling and auxiliary heating or cooling.

[0003] During the test, the operator placed the pycnometer and viscometer in a constant temperature water tank by hand, and kept them still until the constant temperature operation was completed. With this method, on the one hand, manually holding the two experimental instruments consumes the operator's time, energy and physical strength, making the operation time-consuming, laborious and inconvenient. On the other hand, the handheld method cannot control the accurate depth. Even if a bracket is used, it is difficult to flexibly control the preset change of the depth, which reduces the accuracy of the test.

[0004] This case was created to solve the above problems. Utility Model Content

[0020] The utility model is further described in detail below through the drawings and embodiments.

[0021] like Figure 1-2 As shown: a thermostatic bath suitable for specimen inspection, including a thermostatic bath body 1, in which a clamping mechanism is pivotally connected via a rotating rod 2, a support block 3 is provided on the rotating rod 2 to support the bottom of the clamping structure, and a gap is left between the support block 3 and the bottom of the thermostatic bath body 1 to facilitate unobstructed rotation.

[0022] The clamping mechanism includes an insert tube 4 as a bottom support, an extension rod 5 is movably mounted on the insert tube 4 through a bolt 11, and a placement slot 6 is provided at the distal end of the extension rod 5. There are multiple extension rods 5, which are circumferentially mounted on the insert tube 4, each extension rod 5 is independently arranged as required, and two adjacent extension rods 5 have a displacement difference in the vertical direction.

[0023] A rotating handle 7 is also provided on the top of the insert tube 4. The rotating handle 7 can be rotated by an operator to change the position of the tube to be tested in the constant temperature bath.

[0024] The clamping mechanism also includes a fixed plate 8 as an upper limit, and a plurality of arc-shaped through grooves 9 are opened in the circumferential direction of the outer edge of the fixed plate 8, and the position of each arc-shaped through groove 9 corresponds to the position of the lower placement groove 6. A limit ring 10 is hinged at each arc-shaped through groove 9, and the limit ring 10 cooperates with the arc-shaped through groove 9 to form a clamping groove.

[0025] A silicone pad is arranged on the inner side of the limiting ring 10 to form a tight clamping force. Secondly, the limiting ring 10 and the outer edge of the fixing plate 8 can be fixed in a conventional buckling manner.

[0026] The setting of the clamping mechanism eliminates the need for manual adjustment of the lifting and lowering, and the height of the placement slot 6 can be preset in advance before placing it in the constant temperature bath (the bolt 11 is tightened on the outer wall of the insert tube 4 to achieve tightening). At the same time, the specimen can be switched to be placed in different placement slots 6 during use to achieve flexible testing of specimens at different depths, and the detection position can be quickly switched by rotation to change the depth, without the need for manual hand-held experimental specimens for testing, which greatly improves the accuracy of the detection.

Each extension rod 5 is arranged at equal angles along the circumference of the central axis of the cannula 4. Arranging multiple placement grooves 6 of the same depth can be used as a comparative test between specimens.
