However, the traditional Ubbelohde viscometer often faces problems such as unstable fixation, inconvenient adjustment, and inconvenient carrying during use, which affects the measurement accuracy and efficiency. These problems are particularly prominent in field operations or mobile laboratory environments. Therefore, it is particularly important to develop a Ubbelohde viscometer fixture that is both portable and has efficient adjustment and stable fixing functions.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0005] In order to achieve the above-mentioned purpose of the present invention, the following technical solutions are particularly adopted: The invention provides an Ubbelohde viscometer fixing device, comprising: a swastika clamp, the swastika clamp is connected to a folding adjustment frame, the bottom of the folding adjustment frame is arranged on a machine box; a display and a display switch are arranged on the machine box; a press-type box opener is arranged on the surface of the machine box, and a storage space is arranged inside the machine box.

[0006] In the present invention, the swastika clamp is a core device, which is used to adjust and fix the Ubbelohde viscometer according to its size. The folding adjustment frame is convenient for storage and folding, and its height can be adjusted according to the operating habits of the operator. The display and display switch on the machine box can display the situation of the entire device, such as the rotation angle of the swastika clamp, ambient temperature, etc., and can detect the impact of environmental changes on measurement accuracy in real time. The storage space in the machine box can store the Ubbelohde viscometer, matching test tubes, calibration tools, etc., to keep the experimental environment clean and orderly; a portable handle can also be installed according to actual needs to facilitate overall transportation and carrying. Preferably, as a further specific implementation, the fixed edge of the swastika clamp is provided with an arc groove 1, an arc groove 2 and an adjustment surface, and the side corresponding to the fixed edge is provided with two arc grooves, and the size and shape of the two arc grooves are respectively the same as the size and shape of the arc groove 1 and the arc groove 2 set on the fixed edge; the adjustment edge of the swastika clamp is provided with a single semicircular groove, and the side corresponding to the adjustment edge is provided with a semicircular groove of exactly the same shape and size.

[0007] The arc groove 1 and the arc groove 2 are both used to fix different pipes of the Ubbelohde viscometer, wherein the arc groove 1 is used to fix the larger pipe in the Ubbelohde viscometer, and the arc groove 2 is used to fix the smaller pipe. The single semicircular groove is used to fix the swastika clamp on the folding adjustment frame, so that the swastika clamp can be rotated 360 degrees on the folding adjustment frame; at the same time, the swastika clamp can also be stored.

[0008] Preferably, as a further specific implementation, the diameter of the arc-shaped groove 1 is greater than the diameter of the arc-shaped groove 2; and the central angles of the arc-shaped groove 1 and the arc-shaped groove 2 are both 240°.

[0009] The actual diameter of the arc-shaped groove of the swastika clamp can be selected according to the size of the selected Ubbelohde viscometer, but the central angle of the two is 240°, which can better wrap the groove around the Ubbelohde viscometer to achieve fixation and stability of the experimental device.

[0010] Preferably, as a further specific implementation, an adjustment rod is provided on the adjustment surface of the swastika clamp, and the adjustment rod is connected to an adjustment ring; the adjustment ring is located at the center of the swastika clamp.

[0011] The adjustment ring can be adjusted by adjusting the adjustment rod: the adjustment ring itself is a buckle structure, which can be enlarged or extended by adjusting the adjustment rod, so as to fix Ubbelohde viscometers of different sizes.

The maximum arc length of this metal arc is fixed, and the size of the adjusting ring can be changed according to actual use needs. The adjustment base is used to support and fix the elastic expander to prevent the elastic expander from losing its function due to inability to fix.

[0014] Preferably, as a further specific implementation, each of the adjustment bases is connected to an elastic expander; the outside of the elastic expander is a retractable support column, and the inside of the elastic expander is provided with a spring.

[0015] The elastic retractor connects the internal elastic buffer ring and the external adjustable buckle, and can support the two at the same time; in addition, the elastic retractor can also adjust the size of the concentric circles, thereby further achieving the perfect fit and fixation of Ubbelohde viscometers of different sizes.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In order to more clearly explain the technical solution of the present invention, it is described in the form of specific embodiments below.

[0028] Example like Figure 1 As shown, Figure 1 The figure is the overall structure diagram of the Ubbelohde viscometer fixture. It can be seen that the main body of the Ubbelohde viscometer fixture is a machine box 15, on which a display 3 and a display switch 4 are provided. A push-type box opener 18 is provided on the side of the machine box 15. The machine box 15 can be opened by lightly pressing the push-type box opener 18. The machine box 15 has a built-in storage space, which can store the Ubbelohde viscometer, matching test tubes, calibration tools or corresponding maintenance equipment. The display 3 can display various data returned by the sensor 10, such as environmental conditions, the temperature of the Ubbelohde viscometer, the angle of the Ubbelohde viscometer, etc.; at the same time, the display 3 itself is a touch-sensitive display, and the parameters displayed in the display 3 can be touched to adjust the angle of the swastika clip 2 and other related parameters. The display switch 4 is controlled by pressing the display switch 4.

[0029] The side of the machine box 15 is provided with a mounting interface of the folding adjustment frame 1, and the folding adjustment frame 1 is mounted on the mounting interface. The folding adjustment frame 1 itself can be telescopically folded, so as to adjust the height of the Ubbelohde viscometer. A swastika clip 2 is installed on the folding adjustment frame 1 to fix the Ubbelohde viscometer.

[0030] like Figure 2 and Figure 3 As shown, Figure 2 and Figure 3The structure of the swastika clamp can be seen in the figure. One side of the swastika clamp 2 is set as a fixed side, and two arc grooves are set on the fixed side, arc groove 1-16 and arc groove 2-17, the diameter of arc groove 1-16 is greater than arc groove 2-17, in this embodiment, the diameter of arc groove 1-16 is selected to be 2.76mm, the diameter of arc groove 2-17 is selected to be 2.44mm, and the central angle of the two arc grooves is 240°, so as to achieve better coating and fixation of the experimental pipeline of the Ubbelohde viscometer. There is no contact between the arc groove 1-16 and the arc groove 2-17, and there is an adjustment surface between the two, and there is a hole in the adjustment surface, and the adjustment rod 5 of the adjustment ring 7 extends from the hole, and the same arc groove 1-16, arc groove 2-17 and adjustment rod 5 are also set at the corresponding position of the swastika clamp 2.

[0031] A hollow adjustment ring 7 is arranged at the center of the swastika clip 2. The outermost circle of the adjustment ring 7 is an outer metal ring 8. The outer metal ring 8 is composed of four 1 / 4 metal arcs of equal arc length. The metal arcs are provided with threads, and an adjustable buckle 13 is designed between the metal arcs. The metal arcs can be extended and retracted through the adjustable buckle 13 to achieve the adjustment of the outer metal ring 8. A support rod 6 is arranged at a position corresponding to the adjustment buckle 13. A support rod is also arranged at a corresponding position opposite to the support rod 6. The support rod 6 passes through the swastika clip 2 to fix the adjustment ring 7 on the swastika clip 2. The support rod 6 itself does not play a role in actively adjusting the metal arcs. Its main role is to fix the adjustment ring 7 on the swastika clip 2. The clockwise or counterclockwise rotation process of the support rod 6 can realize the swastika clip 2 to rotate 360° on the folding adjustment frame 1.

[0032] A base 14 is provided at the position connected to the inside of the adjustable buckle 13. The base 14 connects the elastic expander 11 and the external metal arc. The base 14 is used to fix and support the elastic expander 11. At the same time, it can also play a buffering role for the elastic expander 11, thereby extending the service life of the elastic expander 11. The elastic expander 11 is a cylindrical elastic retractable device. The elastic expander 11 has a built-in spring 12. The elastic expander 11 is used to adjust the distance between the elastic buffer ring 9 and the outer metal ring 8. In addition, it can also play a supporting and fixing role for the concentric circle structure. The top of the elastic expander 11 passes through the elastic buffer ring 9 and is connected to the sensor 10. The sensor 10 is located inside the elastic buffer ring 9 and is in direct contact with the Ubbelohde viscometer to be fixed.

[0033] The sensor 10 is an integrated sensor 10 that integrates a temperature sensor, an angle sensor, an environment sensor, and a correction sensor. The operator can replace the sensor in the sensor 10 according to actual usage requirements.

[0034] Workflow: The Ubbelohde viscometer itself is divided into three-tube and two-tube types.

[0035] When a three-tube Ubbelohde viscometer is used for fixing, the middle pipeline of the Ubbelohde viscometer is inserted into the elastic buffer ring 9, which can achieve the initial fixation of the middle pipeline of the Ubbelohde viscometer and play a buffering role. At the same time, the thicker pipeline of the Ubbelohde viscometer is fixed in the arc groove 1-16, and the other pipeline is fixed in the arc groove 2-17. The Ubbelohde viscometer is fixed in the swastika clamp 2 in an inclined manner.

[0036] Or, when using a two-tube Ubbelohde viscometer, the thickest pipeline in the Ubbelohde viscometer is fixed in the middle of the elastic buffer ring, and the other thinner pipeline is fixed in the arc groove 2-17, and the Ubbelohde viscometer is fixed in the swastika clamp 2 in an inclined manner.

[0037] When the operator feels that the middle pipeline of the Ubbelohde viscometer is not fixed stably, the operator gently rotates the adjusting rod 5, and the adjusting rod 5 causes the adjustable buckle 13 to shrink or expand.

[0038] When the adjusting rod 5 is rotated to shrink the adjustable buckle 13, the adjustable buckle 13 can screw the thread on the metal arc to shrink it. After shrinking, the base 14 pushes the elastic expander 11 and the built-in spring 12 of the elastic expander 11 to shrink; at the same time, the shrinkage of the elastic expander 11 can drive the elastic buffer ring 9 to shrink, thereby achieving the locking of the small-diameter Ubbelohde viscometer.

[0039] When the adjusting rod 5 is rotated to expand the adjustable buckle 15, the adjustable buckle 13 can screw the thread on the metal arc to expand it. After expansion, the base 14 pushes the elastic expander 11 and the built-in spring 12 of the elastic expander 11 to expand; at the same time, the expansion of the elastic expander 11 can drive the elastic buffer ring 9 to expand, thereby achieving the expansion of the small-diameter Ubbelohde viscometer.

[0040] After fixing the Ubbelohde viscometer, adjust the folding adjustment frame 1 to adjust the height of the Ubbelohde viscometer. Then turn on the display switch 4, and the sensor 10 can display the status of the Ubbelohde viscometer in real time, including the angle, temperature and environmental changes of the Ubbelohde viscometer at this time, and return these data to the display screen 3, so that the operator can record the experimental data and make further adjustments to the experimental process; the system installed in the display screen 3 can process the return data of the sensor 10, and rotate the support rod 6 to assist in adjusting the angle of the Ubbelohde viscometer.

[0041] Compared with the traditional Ubbelohde viscometer fixture, the Ubbelohde viscometer fixture designed in the present invention has a storage space for storing the supporting equipment, which is convenient for overall transportation and carrying. At the same time, the display device contained therein can achieve real-time monitoring of environmental changes, temperature changes and angle changes of the Ubbelohde viscometer through sensors and the software carried thereon. The built-in angle sensor can also assist the operator in calibrating the angle of the Ubbelohde viscometer to ensure the accuracy of the experiment.

[0042] The internal structure of the swastika clamp can adapt to a variety of Ubbelohde viscometers of different sizes and can be adjusted in time according to different devices; at the same time, the adjustment method is simple, and only simple operations are required to achieve adjustment, thereby improving the efficiency of fixing and installation.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
