[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a liquid constant temperature bath flange. The flange includes a substrate 1. A plurality of mounting holes 2 are provided at the top of the substrate 1 according to actual use requirements. A positioning structure 3 is provided below each mounting hole 2 at the bottom of the substrate 1. The positioning structure 3 is a special-shaped frame body. A through space is provided on the positioning structure 3. At least part of the through space is directly communicated with the mounting hole 2. A clamping elastic piece 4 is installed in the through space. One end of the clamping elastic piece 4 is installed on the inner side wall of the positioning structure 3. The other end of the clamping elastic piece 4 is inclined downward and faces the space where the through space is directly communicated with the mounting hole 2, so that one end of the sensor to be inspected passes through the mounting hole 2 and is inserted into the positioning structure 3, and the inclined part of the clamping elastic piece 4 is squeezed downward, thereby realizing the clamping and fixing of the sensor to be inspected, improving the work efficiency of operators and reducing the labor intensity.

[0026] In the above, the clamping elastic piece 4 has a fixing part 5 and a tensioning part 6. The fixing part 5 is detachably installed on the inner side wall of the positioning structure 3 by screws, which is convenient for replacing and maintaining the clamping elastic piece 4. At least one tensioning part 6 is provided. One end of the tensioning part 6 is inclined and installed on the fixing part 5, and the included angle between the tensioning part 6 and the fixing part 5 is less than 90°. The other end of the tensioning part 6 is bent downward to be provided with a pressure-bearing part 7, which is used to improve the service life of the tensioning part 6 and prevent the sensor to be inspected from bending the movable end of the tensioning part 6. In the above, on the opposite sides of the top of the uppermost tensioning part 6, guiding parts 8 are respectively extended upward, forming an inverted V-shaped structure on the top side of the tensioning part 6, and the two groups of guiding parts 8 are located on the opposite sides of the fixing part 5, which is convenient for guiding the sensor to be inspected, so that the sensor to be inspected presses the tensioning part 6 downward along the inverted V-shaped structure, making the tensioning part 6 stressed evenly, and preventing the tensioning part 6 from shifting to one side after long-term use, resulting in unstable clamping of the sensor to be inspected. In this embodiment, two tensioning parts 6 are provided. The two tensioning parts 6 are integrally formed at the upper and lower ends of the fixing part 5 respectively, and the two tensioning parts 6 are arranged in parallel; by adopting a double-layer manganese steel clamping elastic piece 4, it is ensured that each point of the clamping elastic piece 4 is stressed evenly, the sensor to be inspected can be prevented from shifting, and the reliable fixing of the sensor to be inspected is further ensured.

[0027] In the above, as Figure 3As shown, an arc-shaped limiting portion 9 is convexly provided on the side of the positioning structure 3 away from the fixing portion 5. The center line of the arc-shaped limiting portion 9 coincides with the center line of the mounting hole 2, which can increase the effective contact area between the positioning structure 3 and the sensor under test, and further ensure the reliable fixation of the sensor under test. A mesh hole 10 is provided on the peripheral side of the positioning structure 3 to reduce the liquid flow resistance, thereby reducing the influence of the liquid on the temperature field and the fluctuation degree. A lifting lug 11 is extended outward from the top of the positioning structure 3. The positioning structure 3 is detachably installed with the substrate 1 through the lifting lug 11, which is convenient for replacing and maintaining the positioning structure 3; at the same time, a handle 12 is provided on the top of the substrate 1 to facilitate the handling of the flange and assemble it into the liquid thermostat for use.

[0028] In the above embodiment, a convex platform is extended downward from the bottom of the substrate 1 for use in cooperation with the refrigeration tank; when the substrate 1 is used in cooperation with the oil tank, no convex platform is provided at its bottom, aiming to reduce the heat dissipation problem brought by the metal material to the working chamber of the oil tank, while reducing the weight and the processing cost.

[0029] In the above embodiment, the diameter range of the sensor under test is φ3 - φ16. Among them, the aperture sizes of the mounting holes 2 are sequentially set as follows: the number of mounting holes 2 with a φ17mm aperture is 9, the number of mounting holes 2 with a φ12.5mm aperture is 12, and the number of mounting holes 2 with a φ7.5mm aperture is 4; the mounting hole 2 with a φ17mm aperture can fix the sensor under test with a minimum diameter of φ5mm at least, and the mounting hole 2 with a φ7.5mm aperture can fix the sensor under test with a minimum diameter of φ2mm at least.
