[0025] As Figures 1-5The utility model discloses a temperature control device for standard viscosity of viscometer, including base 1, the top slidingly connected with the measurer main part 11 of base 1, the middle part of base 1 is installed heating platform 12, the middle part of base 1 is fixed with two groups of supports 13, the end of support 13 is equipped with two groups of fixed plate 14, two groups of rotating wheels 15 are rotatably connected in the middle part of fixed plate 14, and the middle part of rotating wheel 15 is concave, the inner wall of support 13 is slidably connected with slide rod 16, the end of slide rod 16 is fixedly connected with clamping plate 17, and clamping plate 17 is semicircular, the outer wall of clamping plate 17 is fixedly connected with spring 18, and the other end of spring 18 is fixed on the side wall of support 13, the inner wall of slide rod 16 is fixedly connected with pull rope 19, and pull rope 19 is throughly arranged in the middle part of support 13 and two groups of rotating wheels 15, the end of pull rope 19 is fixedly connected with support plate 110, and support plate 110 is fixedly connected with the side wall of measurer main part 11, when working, after the base 1 is fixed to the workbench surface, can be connected power supply, and the instrument cup with the solution to be detected is placed in the center area of heating platform 12, then after starting heating platform 12 switch, the solution is heated, by being provided with two groups of support plate 110 on the side wall of measurer main part 11, when measurer main part 11 is located at the top, the clamping plate 17 can be expanded and pulled to the outside by the tension of pull rope 19, and then when measurer main part 11 is adjusted, support plate 110 moves downward synchronously, and the tension of pull rope 19 gradually becomes smaller, and the reset force of squeezed spring 18 can make two groups of clamping plate 17 close to the center area of base 1, until the instrument cup on the top of heating platform 12 is fixed, then measurer main part 11 can continue to move downward, until the output end of measurer main part 11 is completely immersed in the solution, and the rotor of output end is rotated, so that the viscosity of the solution is measured, the two groups of clamping plate 17 can move synchronously with measurer main part 11, so that the two groups of clamping plate 17 are closed when measurer main part 11 works, and vice versa, so that the flexibility of clamping plate 17 is improved when fixing the instrument cup, the solution adhered to the rotor is reduced, and the problem of position deviation and sliding of the instrument cup is solved, and the accuracy of viscosity measurement is improved.

[0026] As Figures 1-5As shown, a frame plate 2 is fixedly connected to the outer wall of the bracket 13; a movable rod 21 is slidably connected to the middle of the frame plate 2, and the end of the movable rod 21 is fixedly connected to two sets of fixed plates 14; a support member 22 is fixedly connected to the end of the movable rod 21; an adjusting plate 23 is fixedly connected to the top of the bracket 13; multiple sets of slots 24 are opened in the middle of the adjusting plate 23; a locking pin 25 matching the shape of the slot 24 is slidably connected to the middle of the support member 22; during operation, by setting the adjusting plate 23 on the top of the bracket 13, when the operator needs to adjust the two sets of working positions, the operator can pull the locking pin 25 upwards. After the pin 25 is completely disengaged from the inner wall of the slot 24, the movable rod 21 slides along the inner wall of the frame plate 2, and the locking pin 25 is moved to the designated inner wall of the slot 24. At the same time, the positions of the two sets of rotating wheels 15 are adjusted synchronously. This step, together with the two sets of slidable rotating wheels 15, can improve the flexibility of the pull rope 19 position guidance. The clamping force of the instrument cup can be adjusted according to the different fixed positions of the locking pin 25. At the same time, when the locking pin 25 is locked in the inner wall of the slot 24 at the farthest end, the clamping plate 17 can be completely pulled open to facilitate subsequent maintenance and cleaning.

[0027] like Figures 1-5 As shown, a rotating rod 3 is rotatably connected to the bottom of the support plate 110; multiple sets of top plates 31 are fixed to the middle of the rotating rod 3, and the top plates 31 are set close to the pull rope 19; during operation, by setting a rotatable rotating rod 3 at the bottom of the support plate 110, and the multiple sets of top plates 31 can limit the position of the loose pull rope 19, and the rotating rod 3 can continuously impact the middle of the pull rope 19 while shaking. This step, together with the multiple sets of top plates 31, can reduce the loose pull rope 19 from bending inward and prevent the subsequent operation of the measuring instrument body 11 and the problem of resetting.

[0028] like Figures 1-5 As shown, a counterweight ball 4 is fixedly connected to the top of the locking pin 25; an elastic rope 41 is fixedly connected to the middle of the counterweight ball 4, and both ends of the elastic rope 41 are fixedly connected to the top of the support member 22. During operation, by setting the counterweight ball 4 at the top of the locking pin 25, when the locking pin 25 needs to be pulled, the middle of the counterweight ball 4 can be held directly and the middle of the elastic rope 41 can be stretched. When the locking pin 25 is locked in the inner wall of the designated slot 24, the gravity generated by the counterweight ball 4 and the downward pressure of the elastic rope 41 for resetting will limit and fix the position of the locking pin 25. This step, together with the counterweight ball 4, can improve the stability of the locking pin 25 when it is placed and operated, and further reduce the problem of the locking pin 25 detaching from the slot 24 during its service life.

[0029] like Figures 1-5As shown, two sets of baffles 5 are fixed to the side wall of the rotating wheel 15. During operation, the two sets of baffles 5 are set on the side wall of the rotating wheel 15 and can fix the pull rope 19 in its inner wall area. Under the action of the two sets of baffles 5, the position of the pull rope 19 during operation can be further limited, reducing the problem of it detaching from the rotating wheel 15.

[0030] like Figures 1-5 As shown, a gasket 6 is fixedly connected to the middle of the top plate 31. During operation, the gasket 6 is provided in the middle of the top plate 31. When the gasket 6 collides or contacts the pull rope 19, the soft material gasket 6 can first make contact with the pull rope 19. This step can reduce the wear generated when the two come into contact under the action of the soft material gasket 6.

[0031] Working principle: After fixing the base 1 to the workbench, it can be connected to a power source. The instrument cup containing the solution to be tested is placed in the center of the heating platform 12. Then, the heating platform 12 is turned on to heat the solution. Two sets of support plates 110 are provided on the side wall of the measuring instrument body 11. When the measuring instrument body 11 is at its highest position, the pulling force generated by the pull rope 19 can pull the clamping plate 17 outward. When the measuring instrument body 11 is lowered and adjusted, the support plates 110 will move downward synchronously, causing the pull rope 19 to exert force. As the pulling force gradually decreases, and in conjunction with the restoring force of the compressed spring 18, the two sets of clamping plates 17 can be closed synchronously towards the center area of ​​the base 1 until the top of the heating platform 12 and the instrument cup matching the shape of the two sets of clamping plates 17 are limited and fixed. Then, the measuring instrument body 11 can continue to move downwards until the output end of the measuring instrument body 11 is completely immersed in the solution. Then, the rotor at the output end of the measuring instrument body 11 is rotated to complete the viscosity measurement of the solution. An adjustment plate 23 is set on the top of the bracket 13. Afterwards, the staff will need to adjust the two sets of working positions. When adjusting the position, the operator can pull the locking pin 25 upwards until it is completely disengaged from the inner wall of the slot 24, allowing the movable rod 21 to slide along the inner wall of the frame plate 2, and then move the locking pin 25 to the designated inner wall of the slot 24. Simultaneously, the positions of the two sets of rotating wheels 15 are adjusted synchronously. A rotatable rotating rod 3 is provided at the bottom of the support plate 110, and multiple top plates 31 can limit the position of the loose pull rope 19. The rotating rod 3 continuously impacts the middle of the pull rope 19 while swaying. A counterweight ball 4 is provided at the top of the locking pin 25, and subsequent adjustments are needed. During the pulling of the locking pin 25, the middle part of the counterweight ball 4 can be held directly and the middle part of the elastic rope 41 can be stretched. When the locking pin 25 is locked in the inner wall of the designated slot 24, the gravity generated by the counterweight ball 4 and the downward pressure of the elastic rope 41 returning to its original position will limit and fix the position of the locking pin 25. The two sets of rotating wheels 15 are provided with unfolded baffles 5 on their side walls, and the two sets of baffles 5 can fix the pull rope 19 in their inner wall area. In conjunction with the pad 6 provided in the middle of the top plate 31, when the pad 6 collides or contacts the pull rope 19, the soft material pad 6 can first contact the pull rope 19.
