[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] In view of the problem that the existing prior art cannot control the constant temperature of lubricating oil, resulting in uncertainty of test results, the embodiment provides a kinematic viscosity tester for lubricating oil, please refer to Figures 1-6The embodiment provides a kinematic viscosity tester for lubricating oil, which can improve test accuracy. The kinematic viscosity tester for lubricating oil comprises a detection head 2 installed above a base 1, a detection mechanism 3 for constant-temperature detection of the kinematic viscosity of lubricating oil is arranged on the detection head 2, and a leveling mechanism 4 for overall leveling of the detection mechanism 3 is arranged at the bottom of the base 1. Before the test, the leveling mechanism 4 is used to level the device, so that the device is not slightly inclined and the accuracy of the test is affected. Then the detection mechanism 3 is used to keep the lubricating oil to be detected at a constant temperature, so that the accuracy of the test is improved.

[0032] Since the prior art cannot control the temperature of the lubricating oil, the test result has variables, therefore, the device is provided with the detection mechanism 3. The detection mechanism 3 comprises a threaded connecting sleeve 301 installed at the bottom rear side of the detection head 2, an electric contact 302 is installed on the top wall of the threaded connecting sleeve 301, a temperature sensor 303 is threadedly connected in the threaded connecting sleeve 301, an electrode sheet 304 matched with the electric contact 302 is installed at the top of the temperature sensor 303, an electric heating plate 305 is installed in the mounting bin formed in the base 1, a detection assembly 306 for detecting the kinematic viscosity of the lubricating oil is further arranged on the detection head 2, a lifting assembly 307 for lifting and adjusting the detection head 2 is arranged on the base 1. First, the temperature sensor 303 is screwed into the threaded connecting sleeve 301 at the bottom of the detection head 2 until the electrode sheet 304 at the top of the temperature sensor 303 is in contact with the electric contact 302 on the top wall of the threaded connecting sleeve 301. Then, the electric heating plate 305 is started to heat the lubricating oil in the measuring cup 3064 located thereon. Then, the temperature sensor 303 is immersed in the lubricating oil in the measuring cup 3064. Therefore, the accurate temperature of the lubricating oil in the measuring cup 3064 measured by the temperature sensor 303 can be directly displayed through the digital display controller 308. According to the type and purpose of the lubricating oil, the specific heating temperature of the electric heating plate 305 is set through the digital display controller 308 on the detection head 2, and the temperature is maintained constant, so that the accuracy of the test result is improved.

[0033] The detection assembly 306 comprises a shaft sleeve 3061 installed at the bottom of the detection head 2, a threaded connecting head 3062 is installed at the bottom of the shaft sleeve 3061, a detection rotor 3063 is threadedly connected on the threaded connecting head 3062, and a measuring cup 3064 is placed in the placing groove formed in the base 1. The lubricating oil is poured into the measuring cup 3064 and placed in the placing groove formed in the base 1. Then, the detection rotor 3063 is screwed on the threaded connecting head 3062 at the bottom of the shaft sleeve 3061. The kinematic viscosity of the lubricating oil in the measuring cup 3064 can be detected by rotating the detection rotor 3063 driven by the detection head 2. The detection rotor 3063 is threadedly connected with the threaded connecting head 3062, which is convenient for disassembly and cleaning.

[0034] The outer side of the top connecting part of the detection rotor 3063 is equipped with anti-slip protrusions, and a groove is opened in the middle of the detection rotor 3063, on which a dial is installed. The anti-slip protrusions make it easier to disassemble and install the detection rotor 3063. When measuring the kinematic viscosity of the oil, it is only necessary to observe that the groove in the middle of the detection rotor 3063 is submerged in the oil. When measuring the viscosity of the liquid, the detection rotor 3063 will rotate and drive the oil to move together. At this time, the friction and adhesion of the surface of the detection rotor 3063 will affect the accuracy of the measurement. The groove can reduce the measurement error caused by excessive viscosity and improve the accuracy of the measurement.

[0035] Traditional viscosity testers often require manual adjustment of the height of the test head 2 to submerge the test rotor 3063 into the oil, which is cumbersome. Furthermore, after prolonged use, the locking assembly may loosen, affecting test accuracy. Therefore, this device also includes a lifting assembly 307. The lifting assembly 307 includes a lifting column 3071 mounted on the base 1. A lead screw 3072 is rotatably connected to a U-shaped guide groove on the lifting column 3071, and the lead screw 3072 is threaded with a sliding connection to the guide groove. The inner wall of the groove has a threaded slide 3073, and the front end of the threaded slide 3073 is connected to the detection head 2. The top of the lifting column 3071 is equipped with a lifting motor 3074 that drives the lead screw 3072 to rotate. When it is necessary to control the lifting and adjusting of the detection head 2, the lifting motor 3074 is started to drive the lead screw 3072 to rotate in the guide groove opened on the lifting column 3071, thereby driving the threaded slide 3073 on the lead screw 3072 to move up and down along the inner wall of the guide groove, thereby driving the detection head 2 to move up and down, making the operation simpler and more convenient.

[0036] A digital display controller 308 is installed on the detection head 2, and the detection mechanism 3 is electrically connected to the digital display controller 308. The normal operation of the device is controlled by the digital display controller 308 on the detection head 2.

[0037] Example 2

[0038] Based on Example 1, such as Figures 1-6 As shown, if the platform on which the device is placed is not flat enough, the device may tilt slightly, which will also affect the accuracy of the test. Therefore, the device is also equipped with a leveling mechanism 4. The leveling mechanism 4 includes a bubble level 401 installed on the test head 2, a threaded sleeve 402 installed at the bottom of the base 1, and a threaded rod 403 threadedly connected to the threaded sleeve 402. A round foot 404 is installed at the bottom of the threaded rod 403. When the bubble in the bubble level 401 becomes skewed, the threaded rod 403 is turned up and down to make fine adjustments within the threaded sleeve 402 until the bubble in the bubble level 401 is in the center of the bubble level 401. This ensures the levelness of the device and further improves the accuracy of the test results.
