Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, and particularly relates to a temperature equalizing block bracket for calibrating the temperature of a constant temperature water bath. Background Art

[0002] A constant temperature water bath is an important instrument for laboratory temperature tests, which is a device that maintains the sample at a constant temperature by heating and precisely controlling the water temperature. It is widely used in the fields of biology, chemistry, medicine, and environmental science for operations such as dissolving samples, enzyme reactions, cell culture, and chemical reactions. The constant temperature water bath has functions of uniform heating and safety protection to ensure the stability and safety of the experimental process.

[0003] Currently, there is no calibration specification and calibration device for constant temperature water baths in the country. Each time of calibration, it is measured by holding a thermometer or using a temperature patrol instrument. Since the constant temperature water bath is an electric heating tube heating measuring instrument, the temperature near the heating wire will become higher, and the temperature field in the constant temperature water bath box is uneven and has large fluctuations. When measuring with a hand-held thermometer or using a temperature patrol instrument, it is impossible to fix the thermometer or the temperature patrol instrument on the same plane, resulting in different measurement heights of the thermometer up and down during the calibration of the constant temperature water bath, causing operation errors and being not conducive to on-site measurement of the constant temperature water bath. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a temperature equalizing block bracket for calibrating the temperature of a constant temperature water bath, which can firmly fix the temperature sensor, ensure that it remains on the same plane and at the same position during the measurement process, and avoid operation errors caused by hand-held measurement.

[0005] To solve the above problems, a temperature equalizing block bracket for calibrating the temperature of a constant temperature water bath of the utility model includes a base and a housing arranged on the base. A temperature measuring cavity is arranged in the housing, and a clamping cylinder is arranged in the temperature measuring cavity. The clamping cylinder includes an internal thread pipe, and an external thread pipe is threadedly connected to the internal thread pipe. A lifting slider extending downward is arranged at the center of the external thread pipe, and a clamping groove for inserting a temperature sensor is arranged at the center of the lifting slider. A lifting sliding groove is arranged at the center of the internal thread pipe, and the lifting slider is slidably arranged in the lifting sliding groove. A first conical surface is arranged on the lifting sliding groove, and the internal thread pipe moves downward and presses the lifting slider to make the clamping groove tighten inward.

[0006] The external thread pipe includes a top plate, a side wall is arranged on the top plate, external threads are distributed on the side wall, corresponding internal threads are arranged on the internal thread pipe, and the lifting slider is arranged at the center of the top plate.

[0007] A second conical surface is arranged on the lifting slider, and the second conical surface abuts against the first conical surface.

[0008] The lifting slider is provided with a deformation groove.

[0009] The housing is provided with a plurality of first diversion grooves.

[0010] A tripod is provided under the base. The tripod includes a support. A support rod is hinged on the support. A lifting rod passes through the center of the support. The base is connected to the lifting rod.

[0011] The support rod includes a telescopic cylinder. A telescopic rod is slidably arranged in the telescopic cylinder. A buckle for fixing the telescopic rod is arranged at the lower end of the telescopic cylinder.

[0012] The internally threaded tube is provided with a plurality of second diversion grooves. The lifting chute communicates with the temperature measurement cavity through the second diversion grooves.

[0013] The housing is provided with scales.

[0014] When the utility model is in use, select an appropriate height according to the experimental requirements for temperature calibration. If further adjustment of height or stability is required, extend or retract the support rod, pull out or push back the telescopic rod to the required length, and fix the telescopic rod through the buckle to ensure that the support rod will not slide or retract during use. Next, place the device in a water bath, ensure that the base and the tripod are in a horizontal and stable state, and check whether the connections of all parts are firm and there are no loose components. Next, insert the temperature sensor into the clamping groove in the center of the lifting slider, rotate the internally threaded tube to make it move downward. The first conical surface on the internally threaded tube will squeeze the second conical surface on the lifting slider, causing the lifting slider to move inward. The deformation groove on the lifting slider will produce an appropriate deformation, making the clamping groove tighten and firmly clamp the temperature sensor to ensure that it will not move during the operation for measurement.

[0015] The beneficial effects brought by the utility model are:

[0016] Through the cooperation of the thread and the conical surface, the temperature sensor can be firmly fixed, ensuring that it remains in the same plane and position during the measurement process, and avoiding operation errors caused by manual holding measurement.

[0017] The flow of the internal liquid is optimized through a plurality of diversion grooves, making the entire temperature measurement cavity more uniform, and improving the stability and accuracy of the measurement.

[0018] Through the tripod, the height of the device can be flexibly adjusted to ensure that the temperature sensor can measure at an ideal height, further reducing errors caused by height differences. Description of the Drawings

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] According to Figures 1 to 5As shown in the figure, a temperature equalizing block bracket for temperature calibration of a constant temperature water bath pot of the present utility model includes a base 1 and a housing 2 provided on the base 1. A temperature measuring cavity 3 is provided inside the housing 2. A clamping cylinder 4 is provided inside the temperature measuring cavity 3. The clamping cylinder 4 is composed of an internal threaded tube 5 and an external threaded tube 6. The external threaded tube 6 is threadedly connected to the internal threaded tube 5. By means of threaded connection, the vertical height of the external threaded tube 6 can be adjusted. A lifting slider 7 extending downward is provided at the center of the external threaded tube 6. A clamping groove 8 is provided at the center of the lifting slider 7. The clamping groove 8 is used for inserting a temperature sensor. A lifting chute 9 is also provided at the center of the internal threaded tube 5. The lifting chute 9 cooperates with the lifting slider 7, enabling the lifting slider 7 to slide smoothly within the chute. A first conical surface 10 is provided on the lifting chute 9. When the internal threaded tube 5 moves downward, due to the extrusion of the first conical surface 10, the lifting slider 7 will be extruded, and the clamping groove 8 will tighten inward accordingly, thereby firmly clamping the inserted temperature sensor and ensuring the accuracy and stability of temperature measurement.

[0028] The external threaded tube 6 includes a top plate 11. Side walls 12 are provided on the top plate 11. External threads 13 are evenly distributed on the side walls 12. These external threads 13 correspond to the internal threads 14 on the internal threaded tube 5. Through this threaded connection, the internal and external threaded tubes 6 can be tightly meshed to achieve smooth rotation and adjustment. A lifting slider 7 is provided at the central position of the top plate 11. The lifting slider 7 can move up and down at the center of the top plate 11. A second conical surface 15 is provided on the lifting slider 7. The second conical surface 15 precisely abuts against the first conical surface 10 of the internal threaded tube 5. When the internal threaded tube 5 moves downward, the first conical surface 10 extrudes the second conical surface 15, causing the lifting slider 7 to move inward, thereby tightening the clamping groove 8. A deformation groove 16 is also provided on the lifting slider 7, enabling the lifting slider 7 to generate appropriate deformation when being extruded, ensuring that the clamping groove 8 can firmly clamp the temperature sensor, adapting to minor dimensional changes, and improving the stability and reliability of clamping.

[0029] According to Figure 6 As shown in the figure, a tripod 18 is provided below the base 1. The tripod 18 includes a support 19. A plurality of support rods 20 are connected to the support 19 in a hinged manner, enabling the support rods 20 to flexibly adjust the angle to adapt to different ground environments and usage requirements. A lifting rod 21 passes through the center of the support 19. The base 1 is firmly connected to the lifting rod 21. The lifting rod 21 can move up and down, thereby realizing the adjustment of the height of the base 1. The support rod 20 includes a telescopic cylinder 23. A telescopic rod 24 is slidably arranged inside the telescopic cylinder 23, enabling the length of the support rod 20 to be adjusted as needed. A buckle 26 for fixing the telescopic rod 24 is provided at the lower end of the telescopic cylinder 23. After the telescopic rod 24 is adjusted to the required length, it is fixed by the buckle 26 to ensure that the support rod 20 will not slide or retract during use, thereby improving the stability of the overall structure.

[0030] A plurality of first flow guiding grooves 17 are provided on the housing 2, and a plurality of second flow guiding grooves 25 are provided on the internally threaded tube 5. The lifting sliding groove 9 communicates with the temperature measuring cavity 3 through these second flow guiding grooves 25, enabling the temperature sensor in the temperature measuring cavity 3 to accurately sense and reflect the actual temperature of the fluid, ensuring the accuracy and real-time nature of temperature measurement. A scale is also provided on the housing 2, facilitating intuitive height adjustment by the operator, thereby improving the convenience and accuracy of operation.

[0031] When the present utility model is in use, select an appropriate height according to experimental requirements for temperature calibration. If further adjustment of height or stability is required, extend or retract the telescopic support rod 20, pull out or push back the telescopic rod 24 to the required length, and fix the telescopic rod 24 through the buckle 26 to ensure that the support rod 20 does not slide or retract during use. Next, place the device in a water bath, ensure that the base 1 and the tripod 18 are in a horizontal and stable state, and check whether the connections of all parts are firm and there are no loose components. Next, insert the temperature sensor into the clamping groove 8 at the center of the lifting slider 7, rotate the internally threaded tube 5 to move it downward. The first conical surface 10 on the internally threaded tube 5 will squeeze the second conical surface 15 on the lifting slider 7, causing the lifting slider 7 to move inward. The deformation groove 16 on the lifting slider 7 will undergo appropriate deformation, causing the clamping groove 8 to tighten and firmly clamp the temperature sensor, ensuring that it does not move during operation for measurement.

[0032] The beneficial effects brought by the present utility model are:

[0033] Through the cooperation of the thread and the conical surface, the present utility model can firmly fix the temperature sensor, ensuring that it remains in the same plane and position during measurement, avoiding operation errors caused by hand-held measurement.

[0034] The flow of the internal liquid is optimized through a plurality of flow guiding grooves, making the entire temperature measuring cavity more uniform, and improving the stability and accuracy of measurement.

[0035] The height of the device can be flexibly adjusted through the tripod, ensuring that the temperature sensor can measure at an ideal height, further reducing errors caused by height differences.
