[0002] In existing technologies, the dropping point refers to the lowest temperature at which a lubricating grease begins to drip after melting when heated. It is one of the important indicators of lubricating grease, reflecting its fluidity. The dropping point determines the highest permissible temperature for the lubricating grease during use. Current lubricating grease testing equipment involves placing the lubricating grease in a heated environment and recording the dripping time and temperature by observing the grease's dripping. During the experiment, the experimenter must constantly monitor the dropper to observe and record the experimental data in a timely manner. Furthermore, simultaneous observation is very inconvenient when multiple control groups are included in the experiment. Therefore, a technical solution is needed to address these problems. Utility Model Content

[0020] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-4 As shown, this embodiment discloses a grease dropping point test device, including a heating device 1, a dropper 2, a thermometer 3, a receiving box 4, a weight sensing component 5, a second weight sensor 6, and a housing 7. The heating device 1 is provided with multiple heating channels 11, which can simultaneously conduct multiple sets of experiments, setting up a control group for the dropping point experiment, making the experimental results more accurate and reducing experimental errors. Heating oil can be introduced into the heating device 1 as a heat source, or it can be heated by an electric heating wire. The heating channels 11 connect the upper end face and the lower end face of the heating device 1. The dropper 2 is at least partially located in the heating channel 11. The upper end of the heating channel 11 is opened in the dropper 2, and the lower end of the dropper 2 is provided with a dropping port 21. Grease is added to the dropper 2 before it is placed in the heating channel 11.

[0022] The weight sensing component 5 includes a connecting frame 51 and a first weight sensor 52. The first weight sensor 52 is mounted on a base inside the device, and the connecting frame 51 is mounted on the first weight sensor 52. The first weight sensor 52 can sense the weight change of the connecting frame 51, that is, the weight change of the dropper 2. When the grease in the dropper 2 reaches the dropping point, it drips, and the weight of the grease decreases. The first weight sensor 52 senses the weight change and sends a signal to the control system. The control system records the temperature data on the thermometer 3 at that time and automatically calculates the temperature of the dropping point. Part of the connecting frame 51 extends into the heating channel 11. The upper end of the connecting frame 51 supports the dropper 2. The connecting frame 51 includes a support ring 511 and a support plate 512. The support ring 511 and the support plate 512 are arranged vertically at intervals. The support ring 511 is located inside the heating channel 11, and the support plate 512 is located outside the heating channel 11. The support plate 512 is installed on the first weight sensor 52. The support ring 511 supports the dropper 2. The support ring 511 is annular. The center of the support ring 511 can allow the drip nozzle 21 to pass through. The support ring 511 forms a limit for the dropper 2 inside the heating channel 11. The lower end of the drip nozzle 21 is higher than the lower opening of the heating channel 11, so that the temperature of the drip nozzle 21 can be maintained.

[0023] The thermometer 3 is located inside the dropper 2. The lower end of the thermometer 3 is close to the dropper opening 21. The thermometer 3 can more accurately measure the temperature at the drop point. The upper end of the dropper 2 has an opening. The upper end of the dropper 2 is higher than the upper opening of the heating channel 11, making it convenient to pick up the dropper 2.

[0024] The receiving box 4 is located below the dropper 2. The receiving box 4 includes a box body 41 and a mounting base 42. The box body 41 has a receiving groove 411 facing the drip nozzle 21. The receiving groove 411 can receive the grease dripping from the drip nozzle 21. The support plate 512 has a through hole 5121 through which the box body 41 passes, allowing the box body 41 to be close to the drip nozzle 21, reducing the distance between the receiving groove 411 and the drip nozzle 21, and reducing the time for the grease to drip. The lower end of the box body 41 has a screw 412, and the upper end of the mounting base 42 has a threaded seat 421. The screw 412 and the threaded seat 421 are threadedly connected. The box body 41 can be close to or away from the mounting base 42. When the box body 41 is in the lowest position, the upper end of the box body 41 is lower than the lower end of the support plate 512. The receiving box 4 can be disassembled and installed for easy cleaning after testing.

[0025] Mounting base 42 is detachably mounted on the second weight sensor 6. The receiving box 4 is mounted on the second weight sensor 6. The second weight sensor 6 can sense the weight change of the receiving box 4 and also obtain the temperature of the drip point. This prevents the first weight sensor 52 from malfunctioning. The second weight sensor 6 can also sense the dripping of lubricating grease in a timely manner, thus playing a safety role.

[0026] The outer casing 7 serves to protect the internal components. The upper surface of the outer casing 7 is provided with a through groove 71. The upper end of the dropper 2 extends out of the through groove 71. The outer casing 7 is provided with a bracket 72, which is detachably installed on the outer casing 7. Part of the bracket 72 is located above the through groove 71. The thermometer 3 is installed on the bracket 72. The upper end of the thermometer 3 can abut against the upper surface of the bracket 72. The bracket 72 limits the height of the lower end of the thermometer 3.
