Technical Field

[0001] This utility model belongs to the field of viscometer technology, specifically an adjustable viscometer. Background Technology

[0002] Viscosity measurement is a key step in assessing fluid properties, monitoring production processes, and ensuring product quality in various fields such as industrial production, scientific research, and quality control.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides an adjustable viscometer. A base is used to load and support telescopic rods and a support frame. Multiple telescopic rods fixedly installed on the top of the base load a support platform, enabling the platform to be raised and lowered. The support platform, fixedly mounted on the top of the telescopic rods, loads containers of the viscometer's test products and moves the containers up and down together, achieving adjustability in the viscometer's use. An electric push rod fixedly installed on the base and below the support platform drives the platform's raising and lowering.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4 This utility model provides an adjustable viscometer, including a base 1, a plurality of telescopic rods 2 fixedly installed on the top of the base 1, a support platform 3 fixedly installed on the top of the telescopic rods 2, an electric push rod 10 fixedly installed on the base 1 and below the support platform 3, the top of the electric push rod 10 being connected to the support platform 3, a loading seat 4 fixedly installed on the top of the support platform 3, an adjustment mechanism being provided on the loading seat 4, an arc plate 8 being provided on the support platform 3 and inside the loading seat 4, a support frame 11 fixedly installed on the top of the base 1 and outside the support platform 3, a top seat 12 fixedly installed on the top of the support frame 11, a viscometer 13 fixedly installed on the top of the top seat 12, and a limit mechanism being provided at the bottom of the top seat 12;

[0025] During operation, the base 1 is used to load and support the telescopic rods 2 and the support frame 11. Multiple telescopic rods 2, fixedly installed on the top of the base 1, are used to load the support platform 3 and enable its lifting and lowering. The support platform 3, fixedly mounted on the top of the telescopic rods 2, is used to load the container for the viscometer test product and can move the container up and down together, achieving adjustable operation of the viscometer. The test product container is typically a glass bottle, which is mature existing technology and will not be elaborated upon further in this paper. An electric push rod 10, fixedly mounted on the base 1 and located below the support platform 3, drives the support platform 3 to lift and lower. Since the top of the electric push rod 10 is connected to the support platform 3... Connected, as the support platform 3 rises and falls, the electric push rod 10 retracts synchronously to ensure the stability of the support platform 3 during the rising and falling process. The loading seat 4 fixedly installed on the top of the support platform 3 is used to load the adjustment mechanism. The adjustment mechanism set on the loading seat 4 is used to control the retraction of the arc plate 8 to clamp the container and ensure the stability of the container when it moves. The arc plate 8 set on the support platform 3 and located on the inner side of the loading seat 4 is in direct contact with the container. The support frame 11 fixedly installed on the top of the base 1 and located on the outer side of the support platform 3 is used to load the top seat 12. The top seat 12 fixedly installed on the top of the support frame 11 is used to load the viscometer 13.

[0026] The viscometer 13 mainly consists of a rotor, a motor, a rotating shaft, and a display. The liquid to be tested is placed in a container, and then the motor is started. The motor drives the rotating shaft to rotate, and the rotating shaft drives the rotor to rotate. When the rotor rotates, the liquid is forced to rotate with the rotor, generating shear force and causing the liquid to flow. By measuring the rotor speed and rotor torque, the rotational viscometer can calculate the viscosity of the liquid.

[0027] The limiting mechanism set at the bottom of the top seat 12 is used to limit the rotation shaft 21 to ensure the accuracy of the test data.

[0028] Furthermore, such as Figure 3 As shown, the adjustment mechanism includes a threaded hole 5 through the loading seat 4, a handle screw 6 threadedly connected to the inside of the threaded hole 5, a rotating connecting seat 7 rotatably mounted on the handle screw 6, and the rotating connecting seat 7 fixedly mounted on the arc plate 8.

[0029] During operation, the threaded hole 5 through the loading seat 4 is used to load the handle screw 6 and to limit the extension length of the handle screw 6. The handle screw 6 connected by the inner thread of the threaded hole 5 is used to load the rotating connecting seat 7 and drive the rotating connecting seat 7 to hold the arc plate 8, so as to realize the clamping of the container by the arc plate 8.

[0030] Furthermore, such as Figure 3As shown, the top of the support platform 3 is provided with an anti-slip groove 9;

[0031] During operation, the anti-slip groove 9 on the top of the support platform 3 serves to prevent slippage when the container is first placed on the support platform 3, thus preventing the container from falling before it is clamped.

[0032] Furthermore, such as Figure 4 As shown, the limiting mechanism includes a limiting seat 14 fixedly installed at the bottom of the top seat 12. A limiting groove 15 is provided on the limiting seat 14. A sliding ball 16 is slidably installed on the inner side of the limiting groove 15. A first connecting rod 17 is fixedly connected to the sliding ball 16. A second connecting rod 18 is hinged to the end of the first connecting rod 17 away from the sliding ball 16. A limiting plate 19 is fixedly installed on the second connecting rod 18. A sliding hole 20 is provided in the middle of the limiting plate 19.

[0033] During operation, the limiting seat 14 fixedly installed at the bottom of the top seat 12, in conjunction with the limiting groove 15, is used to load the sliding ball 16. The sliding ball 16 can move in a circular path inside the limiting groove 15. The sliding ball 16, which is slidably installed inside the limiting groove 15, is used to load the first connecting rod 17. The first connecting rod 17, which is fixedly connected to the sliding ball 16, is used to load the second connecting rod 18 and can drive the second connecting rod 18 to move together. The second connecting rod 18, which is hinged to the end of the first connecting rod 17 away from the sliding ball 16, can make the limiting plate 19 rise and fall. It also works with the sliding hole 20 opened on the limiting plate 19 to limit the rotating shaft 21, ensuring the accuracy of the device during testing.

[0034] Furthermore, such as Figure 1 As shown, a rotating shaft 21 is provided on the viscometer 13, and a rotor 22 is provided at the bottom of the rotating shaft 21. The rotating shaft 21 passes through the inner side of the sliding joint hole 20.

[0035] During operation, the rotor 22 is mounted on the rotating shaft 21 on the viscometer 13, and the rotor 22 directly contacts the liquid to test its viscosity.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
