Technical Field

[0001] The utility model relates to the technical field of viscometers, in particular to a rotary viscometer. Background Art

[0002] A rotary viscometer is a commonly used viscosity testing instrument, usually used to measure the viscosity of liquids or semi-solids. Its principle is to rotate a rotating cylinder or sphere in the substance to be tested, and then measure the required torque or force to determine the viscosity of the substance, which can help laboratories and production sites determine the viscosities of different substances to ensure product quality and production process stability.

[0003] In order to facilitate the detection of the viscosity of substances, a rotary viscometer needs to be used for detection. For example, the Chinese patent publication number "CN205246486U" in the prior art discloses a rotary viscometer, and the key points of its technical solution are: including a base, a column is vertically arranged on the base, a detection motor is slidably arranged on the column, the output shaft of the detection motor is connected with a rotor for detecting the viscosity of the liquid in the beaker, and a clamping component for fixing the beaker is arranged on the base. By setting the clamping component, when detecting the liquid in the beaker, the clamping component can clamp the beaker, and the beaker can be stably fixed below the rotor, which can avoid the beaker from tipping during detection and improve the safety of the equipment.

[0004] Some rotary viscometers fix the beaker through a pair of feet arranged on the base. However, in specific operations, considering that it is necessary to adjust the screws on both sides to adjust the distance between the feet, and it is impossible to adjust a pair of feet simultaneously, which causes inconvenience in operation. In addition, considering that the viscosities of different substances are different, if there is no measure to close the beaker when the rotation speed of the detection motor is too fast, the substances in the beaker may splash. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art that it is impossible to adjust a pair of feet simultaneously, resulting in inconvenient operation, and when the rotation speed of the detection motor is too fast, the substances in the beaker may splash, and a rotary viscometer is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a rotary viscometer, including a base, a detection motor is arranged on the top of the base through a driving member, the driving member is used to drive the detection motor to lift, a detection container is placed below the detection motor on the top of the base, and a fixing component for clamping the detection container is arranged inside it;

[0008] Among them, the fixing component further includes a splash-proof component, and the splash-proof component is used to close the opening of the detection container.

[0009] Furthermore, the fixing component includes an installation groove formed inside the base. A fixing seat is fixedly installed in the installation groove. On both sides of the detection container at the top of the base, a pair of sliding grooves communicating with the installation groove are opened. On both sides of the top of the fixing seat, clamping blocks are slidably connected in the sliding grooves through slide rails, and the pair of clamping blocks can clamp and fix the detection container.

[0010] Furthermore, a movable seat is slidably connected below the fixing seat in the installation groove. L-shaped rods are rotatably connected to both sides of the end face of the fixing seat.

Connecting shafts are fixedly installed on the sides of the movable seat and the pair of clamping blocks, and the pair of connecting shafts are respectively slidably connected in the long sliding groove and the short sliding groove.

[0011] Furthermore, a lead screw and a worm are rotatably connected in the installation groove. The lead screw is threadedly connected to the movable seat, and a worm gear is fixedly installed at the bottom of the lead screw. The worm meshes with the worm gear and rotates, and a hand wheel is provided at the other end of the worm.

[0012] Furthermore, the splash-proof component includes a support frame. One end of the support frame is fixedly connected to the driving member, and the other end extends towards the side of the detection container. Connecting arms are slidably connected to both sides of the support frame. A cover plate is fixedly installed at the top of the connecting arm, and a spring is sleeved around the periphery of one end of the top of the connecting arm.

The advantage of this is that it can avoid the situation that the materials in the detection container are splashed due to the too fast rotation speed of the detection motor. The structure is simple, the operation is convenient, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0021] 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.

[0022] Refer to Figures 1-5 , a rotary viscometer, including a base 1, a detection motor 3 is arranged on the top of the base 1 through a driving member 2, the driving member 2 is used to drive the detection motor 3 to lift, a detection container 4 is placed below the detection motor 3 on the top of the base 1, and a fixing component 5 for clamping the detection container 4 is arranged inside it;

[0023] Among them, the fixing component 5 further includes an anti-sputtering component 6, and the anti-sputtering component 6 is used to close the opening of the detection container 4.

[0024] It is worth mentioning that the driving member 2 includes an electric push rod 21 fixedly installed on one side of the top of the base 1, the output end of the electric push rod 21 is fixedly installed with the detection motor 3 through a cross plate, the output end of the detection motor 3 is connected with a detection rotor 31, and the height of the detection motor 3 can be adjusted by using the electric push rod 21.

[0025] Furthermore, the fixing component 5 includes an installation groove 51 formed inside the base 1. A fixing seat 52 is fixedly installed in the installation groove 51. On the top of the base 1, a pair of sliding grooves 53 communicating with the installation groove 51 are formed on both sides of the detection container 4. On both sides of the top of the fixing seat 52, clamping blocks 55 are slidably connected in the sliding grooves 53 through sliding rails 54. The pair of clamping blocks 55 can clamp and fix the detection container 4.

[0026] Furthermore, a movable seat 56 is slidably connected below the fixing seat 52 in the installation groove 51. On both sides of the end face of the fixing seat 52, L-shaped rods 57 are rotatably connected. Long sliding grooves 571 and short sliding grooves 572 are respectively formed at both ends of the L-shaped rod 57. Connecting shafts 58 are fixedly installed on the sides of the movable seat 56 and the pair of clamping blocks 55. The pair of connecting shafts 58 are respectively slidably connected in the long sliding groove 571 and the short sliding groove 572.

[0027] More specifically, a lead screw 59 and a worm 591 are rotatably connected in the installation groove 51. The lead screw 59 is threadedly connected to the movable seat 56, and a worm gear 592 is fixedly installed at the bottom of the lead screw 59. The worm 591 meshes with the worm gear 592 for rotation, and a handwheel is provided at the other end of the worm 591.

[0028] It is worth mentioning that by rotating the worm 591 through the handwheel, the worm gear 592 is driven to drive the lead screw 59 to rotate. The purpose is to drive the movable seat 56 to move up and down due to the threaded connection between the lead screw 59 and the movable seat 56. In this way, the movable seat 56 drives the L-shaped rod 57 to rotate by means of the connecting shaft 58 provided on its own side.

[0029] It should be noted that because one end of the bottom of the L-shaped rod 57 is pulled by the sliding of the movable seat 56, the other end of the top then drives the clamping block 55 to move by means of the connecting shaft 58, and the pair of clamping blocks 55 can clamp the detection container 4.

[0030] Among them, an anti-slip pad is provided between the opposite sides of the pair of clamping blocks 55.

[0031] Generally speaking, the anti-sputtering component 6 includes a support frame 61. One end of the support frame 61 is fixedly connected to the driving member 2, and the other end extends towards the side of the detection container 4. Connecting arms 62 are slidably connected to both sides of the support frame 61. A cover plate 63 is fixedly installed at the top of the connecting arm 62, and a spring 64 is sleeved around one end of the top of the connecting arm 62. Both ends of the spring 64 are fixedly connected to the side of the cover plate 63 and the support frame 61 respectively.

[0032] Finally, at the bottom of a pair of the connecting arms 62, a connecting rod 65 is rotatably connected through a rotating seat 621. The other end of the connecting rod 65 is rotatably connected to the top of the clamping block 55. One side of one end of the bottom of a pair of the connecting rods 65 facing each other is inclined.

[0033] It is worth mentioning that because one side of one end of the bottom of a pair of the connecting rods 65 facing each other is inclined, when a pair of the clamping blocks 55 move towards each other, the connecting rods 65 can be driven to rotate, and then the connecting rods 65 pull the connecting arms 62 to make the cover plate 63 close the opening of the detection container 4.

[0034] Among them, it should be noted that the cover plate 63 has a circular structure, and both sides thereof are fixedly connected to the connecting arms 62 through connecting ears. An avoidance groove is formed at the center point of the end face of the cover plate 63 to prevent the detection rotor 31 from being stuck and rotating.

[0035] Working mode: During work, the detection container 4 containing substances is placed above the base 1 and below the cover plate 63. The electric push rod 21 drives the detection motor 3 to descend to insert the detection rotor 31 into the detection container 4.

[0036] Then, the worm 591 is rotated through the handwheel, and then the worm wheel 592 is driven to drive the lead screw 59 to rotate. Due to the threaded connection between the lead screw 59 and the movable seat 56, the movable seat 56 is driven to lift and lower. The movable seat 56 uses a pair of L-shaped rods 57 to drive a pair of clamping blocks 55 to move towards each other simultaneously to clamp and fix the detection container 4.

[0037] Finally, when a pair of clamping blocks 55 move towards each other, the connecting rods 65 will be driven to rotate. Under the action of the rotating seats 621, a pair of the connecting rods 65 pull the connecting arms 62 to make the connecting arms 62 drive the cover plate 63 to descend, achieving the effect of closing the opening of the detection container 4.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
