[0028] The titration device for polymer lubricating material quality test includes:

[0029] Test subject 1;

[0030] Lifting adjustment mechanism, the lifting adjustment mechanism is provided on both sides of the test body 1, the lifting adjustment mechanism includes a rack 2, a rotating shaft 3, a gear 4, a docking device 5 and a test tube fixing platform 6, the rack 2, the rotating shaft 3, the gear 4 and the docking device 5 are each provided with two, the two racks 2 are respectively provided on both sides of the test body 1, the two rotating shafts 3 are respectively rotatably connected to the two side ends of the test body 1, the two gears 4 are respectively fixedly connected to the circumferential surface of the two rotating shafts 3, the gear 4 and the rack 2 are meshed, the front ends of the two docking devices 5 are respectively fixedly connected to the two racks 2, the test tube fixing platforms 6 are fixedly connected to the lower ends of the two docking devices 5, and the test tube fixing platform 6 is slidably connected to the test body 1;

[0031] Locking structure: The locking mechanism is provided on both sides of the test body 1.

[0032] In a specific embodiment of the present invention, one of the core parts of the polymer lubricating material quality test titration device is a lifting and adjusting mechanism, which is arranged on both sides of the test body 1 and consists of a rack 2, a rotating shaft 3, a gear 4, a docking device 5 and a test tube fixing platform 6. The two racks 2 are respectively placed on both sides of the test body 1, and correspondingly, the two rotating shafts 3 are rotatably connected to the two side ends of the test body 1. The circumferential surface of the rotating shaft 3 is fixedly connected with a gear 4, and the gear 4 is meshed with the rack 2 to form a transmission chain. The front ends of the two docking devices 5 are respectively fixedly connected to the two racks 2. The setting of the docking device 5 ensures the stable lifting and lowering of the test tube fixing platform 6, and the test tube fixing platform 6 is slidably connected to the test body 1. To ensure stability during the lifting process, when the height of the test tube fixing platform 6 needs to be adjusted, the operator only needs to rotate the rotating shaft 3, and through the engagement of the gear 4 and the rack 2, the rotational motion of the rotating shaft 3 is converted into the linear motion of the rack 2, thereby driving the docking device 5 to move up and down, and finally realizing the lifting and lowering of the test tube fixing platform 6. This linkage mechanism ensures the precise adjustment of the height of the test tube fixing platform 6, adapts to different experimental requirements, and improves the accuracy and flexibility of the titration test. The locking structure is provided on both sides of the test body 1, and the test tube fixing platform 6 can be locked after it is adjusted to the appropriate position to avoid the experimental results being affected by accidental movement during the test, thereby enhancing the stability and reliability of the experiment.

[0033] For details, please refer to Figures 1-4The locking mechanism includes a matching slider 7, a rebounder 8, a locking block 9 and a toggle pull tab 10. There are two matching sliders 7, rebounder 8, locking block 9 and toggle pull tab 10. The two matching sliders 7 are respectively fixedly connected to the two side ends of the test body 1, the two rebounders 8 are respectively slidably connected to the two matching sliders 7, the two locking blocks 9 are respectively fixedly connected to the front ends of the two rebounders 8, and the two toggle pull tabs 10 are respectively fixedly connected to the outer surfaces of the two rebounders 8.

[0034] In this embodiment: the locking mechanism is composed of a matching slider 7, a rebounder 8, a locking block 9 and a toggle pull tab 10. There are two of these components, which are respectively installed on both sides of the test body 1. The two matching sliders 7 are fixedly connected to the two side ends of the test body 1, providing a sliding track for the rebounder 8. The rebounder 8 is slidably connected to the matching slider 7. Its internal spring structure can generate a rebound force after being subjected to force, ensuring the stability of the locking block 9. The locking block 9 is fixedly connected to the front end of the rebounder 8. When the rebounder 8 moves in the matching slider 7, the locking block 9 also moves accordingly and can be stuck in the corresponding groove or interface of the gear 4 to achieve locking of the test tube fixing platform 6.

[0035] For details, please refer to Figures 1-4 The front ends of the two rotating shafts 3 are fixedly connected to two turning handles 11 respectively.

[0036] In this embodiment: the front ends of the two rotating shafts 3 are respectively fixedly connected to two turning handles 11, which provides an intuitive and convenient control means for the operator. The setting of the turning handles 11 enables the operator to easily apply force to the rotating shafts 3 and drive the rotating shafts 3 to rotate by rotating the turning handles 11.

[0037] For details, please refer to Figures 1-4 Two sliding grooves 12 are respectively provided on both side ends of the test body 1, and two first limit sliders 13 are respectively slidably connected in the two sliding grooves 12, and the front ends of the two first limit sliders 13 are respectively fixedly connected to two racks 2.

[0038] In this embodiment: the two sliding grooves 12 respectively opened at the two side ends of the test body 1 provide sliding tracks for the first limit slider 13, ensuring the smooth movement of the rack 2. The sliding connection between the first limit slider 13 and the sliding groove 12 not only limits the movement direction of the rack 2, ensuring that it can only move in a straight line along a predetermined trajectory, but also provides guidance and support for the movement of the rack 2 through the contact between the slider and the groove wall, thereby enhancing the stability and accuracy of the entire transmission system.

[0039] For details, please refer to Figures 1-4 A rubber fixing ring 14 is fixedly connected to the test tube fixing platform 6, and two side ends of the test tube fixing platform 6 are respectively fixedly connected to two second limiting sliders 15, and two second limiting sliders 15 are slidably connected to the test body 1.

[0040] In this embodiment: the rubber fixing ring 14 fixedly connected inside the test tube fixing platform 6 is designed to provide flexible fixation of the test tube, ensuring that the test tube is stable and not damaged during the test process. The selection of rubber material, due to its good elasticity and friction coefficient, can adapt to test tubes of different diameters, provide sufficient gripping force, and avoid scratching the surface of the test tube. It is particularly suitable for the gentle fixation of test tubes in the quality test of polymer lubricating materials. The two second limiting sliders 15 fixedly connected to the two side ends of the test tube fixing platform 6, and the sliding connection design in the test body 1, together constitute a limiting system during the platform lifting process. The sliding of the second limiting slider 15 in the test body 1 not only guides the vertical movement of the test tube fixing platform 6, ensuring the linearity and stability of its lifting path, but also improves the rigidity and precision of the entire system by limiting the lateral movement of the platform.

[0041] For details, please refer to Figures 1-4 The upper end of the test body 1 is fixedly connected to a magnetic cover 16 , and the front end of the test body 1 is fixedly connected to a controller 17 .

[0042] In this embodiment: the magnetic cover 16 fixedly connected to the upper end of the test body 1 provides a closed environment during the experiment, which is particularly important for the quality testing of polymer lubricating materials. The magnetic cover 16 is adsorbed on the test body 1 by magnetic force, ensuring the tight closure of the cover. The controller 17 fixedly connected to the front end of the test body 1 is the operating center of the entire device.

[0043] The working principle and usage process of the present invention are as follows: first, the experimental parameters, such as the target titration volume, rate, etc., are preset through the controller 17. Then, according to the experimental requirements, the operator rotates the handle 11 to drive the rotating shaft 3 to rotate, and adjusts the test tube fixing platform 6 to a suitable height through the engagement of the gear 4 and the rack 2 to accommodate test tubes of different lengths. At this time, the first limit slider 13 slides in the sliding groove 12 to ensure the linearity and stability of the platform lifting. When the test tube fixing platform 6 is adjusted to the right position, the operator controls the rebounder 8 by toggling the pull tab 10 to extend the locking block 9 and engage the locking point of the gear 4 to fix the platform. The rubber fixing ring 14 ensures that the test tube is stable on the platform without being damaged. The second limit slider 15 is in the test main The sliding inside the body 1 further improves the accuracy and stability of the platform lifting. During the experiment, the magnetic cover 16 remains closed, providing a closed environment for the experiment and reducing interference from external factors. After the titration is completed, the operator unlocks it by toggling the pull tab 10 again, adjusts the height of the test tube fixing platform 6, and conducts the next round of experiments or cleaning. By using this device, the problem of traditional lubricating material quality test titration device being unable to adapt to test tubes of different sizes will be solved, which will limit its scope of use, thereby affecting its versatility and practicality. Because the tester cannot adapt to test tubes of various sizes, it may not be able to test samples of certain sizes, which makes it less flexible and universal under diverse testing needs.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
