Description

Technical Field

[0001] This utility model relates to the field of windshield washer fluid testing technology, and in particular to a windshield washer fluid antifreeze testing device. Background Technology

[0002] Automotive windshield washer fluid is widely used for the rapid cleaning and brightening of various types of glass, including automotive glass, rearview mirrors, household glass, office glass, door and window glass, and decorative glass. It boasts comprehensive functions and is easy to use. Generally, windshield washer fluid on the market is divided into three main categories: the first is 0℃ windshield washer fluid for summer use; the second is antifreeze windshield washer fluid specifically designed for winter use, ensuring it will not freeze at -20℃; and the third is a high-efficiency antifreeze windshield washer fluid, ensuring it will not freeze at -40℃.

[0003] To ensure the quality of windshield washer fluid production, antifreeze testing is necessary for winter-use fluid to guarantee its proper function in cold winter conditions. Antifreeze testing is typically conducted in a laboratory. A container filled with windshield washer fluid is placed in a refrigerator and left to stand for a period of time. The fluid is then removed and observed to determine if it has frozen, thus providing the antifreeze test result. To quickly test the antifreeze of windshield washer fluid at various temperature gradients, existing antifreeze testing equipment uses multiple refrigerators simultaneously, adjusting their cooling temperatures to create a gradient. This process requires personnel to move back and forth between the refrigerators, which is not only physically demanding but also time-consuming. Furthermore, personnel are prone to spilling windshield washer fluid, causing contamination of the laboratory. Utility Model Content

[0004] The purpose of this application is to provide an antifreeze testing device for automotive windshield washer fluid, in order to conduct antifreeze testing of windshield washer fluid under various temperature gradients in a short time. Existing antifreeze testing devices for windshield washer fluid use multiple refrigerators simultaneously to conduct experiments, and adjust the cooling temperature of multiple refrigerators to change in a gradient to conduct antifreeze testing of the same windshield washer fluid under multiple temperature gradients. In this process, the experimenter needs to go back and forth between multiple refrigerators, which not only consumes too much physical strength, but also takes a long time. When the experimenter goes back and forth, the windshield washer fluid is easily spilled, causing pollution to the laboratory.

[0005] To achieve the above objectives, this application provides the following technical solution: an automotive windshield washer fluid antifreeze detection device, comprising a base and a power plug. A carrier column is rotatably connected to the upper surface of the base via a bearing. An insulating block is fixedly sleeved on the outside of the carrier column. Three contact rings are installed on the insulating block, arranged parallel from top to bottom. The power plug is tightly fitted with the three contact rings. A support plate is fixed to the top of the carrier column, and a first gear is fixedly sleeved on the outside of the carrier column. A drive assembly is installed on the base, used to drive the first gear to rotate. Several refrigerators are placed on the upper surface of the support plate, and a power socket is installed on the upper surface of the support plate. The power socket is connected to the three contact rings via a wire.

[0006] Furthermore, an insulating protective shell is fixed on the base, the insulating protective shell is sleeved on the outside of the carrier column and the insulating block, and the power supply plug is fixedly installed on the insulating protective shell.

[0007] Furthermore, the upper surface of the tray is provided with several reserved slots, and the refrigerator is placed in the reserved slots.

[0008] Furthermore, the drive assembly includes a drive motor, which is mounted on the base, and a second gear is fixed to the output shaft end of the drive motor, the second gear meshing with the first gear.

[0009] Furthermore, a number of columns are fixed on the upper surface of the base, and the columns are arranged in a circular array. The top of each column is embedded with a ball bearing, which can rotate freely at the top of the column.

[0010] Furthermore, the lower surface of the tray is provided with an annular groove, and the ball is in close contact with the inner wall of the annular groove.

[0011] Furthermore, a carrier plate is fixed to the periphery of the base, a support rod is fixed to the top of the carrier plate, and a supplementary light is installed at the top of the support rod.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, a tray is used to simultaneously support several refrigerators. With the help of a drive component, the first gear can be rotated, which in turn drives the carrier column and the tray on it to rotate. In this way, the several refrigerators supported on the tray can rotate as needed. The experimenter only needs to stand still in the designated position to extract the glass cleaner stored in several refrigerators in an orderly manner and obtain the antifreeze test results of the glass cleaner. The experimenter does not need to walk back and forth, which not only saves time and effort, but also makes it less likely to cause the glass cleaner to spill.

[0014] 2. In this utility model, three connecting rings installed on the insulating block are connected to the power supply plug, so that the city power supply can be conducted to the connecting rings along the power supply plug. The connecting rings then conduct the power to the power socket, which can supply power to several refrigerators, so that the power supply to the refrigerators will not be affected when the tray rotates.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: Reference Figure 1-5The illustrated automotive windshield washer fluid antifreeze testing device includes a base 1 and a power plug 2. The power plug 2 is electrically connected to a city power supply line. A carrier column 3 is rotatably connected to the upper surface of the base 1 via a bearing. An insulating block 4 is fixedly sleeved on the outside of the carrier column 3. Three contact rings 5 ​​are installed on the insulating block 4, arranged parallel from top to bottom, and corresponding to the neutral wire, live wire, and ground wire, respectively. The power plug 2 is tightly fitted with the three contact rings 5 ​​to supply power to them. A support plate 6 is fixed to the top of the carrier column 3, and a first gear 7 is fixedly sleeved on the outside of the carrier column 3. A drive assembly is installed on the base 1 to drive the first gear 7 to rotate. Multiple ice cubes are placed on the upper surface of the support plate 6. The refrigerator 9 is placed in a tray 6, and a power socket 8 is installed on the upper surface of the tray 6. The upper surface of the tray 6 has multiple reserved slots. The refrigerator 9 is placed in the reserved slots, which makes the refrigerator 9 more stable when placed on the tray 6. The power socket 8 is connected to three contact rings 5 ​​through wires. The power plug 2 can supply power to the power socket 8 through the contact rings 5. The power socket 8 can supply power to multiple refrigerators 9. The models of the multiple refrigerators 9 are: Haier DW-86L338J refrigerator, temperature range: -40℃ to -86℃; Xinyu XY-40-158L refrigerator, temperature range: -15℃ to -45℃; Midea BD / BC-102KWH refrigerator, temperature range: -26℃ to 10℃.

[0024] Multiple refrigerators 9 can be supported simultaneously using a pallet 6. With the help of a drive assembly, the first gear 7 can be rotated, which in turn drives the carrier column 3 and the pallet 6 on it to rotate. In this way, the multiple refrigerators 9 supported by the pallet 6 can rotate as needed. The experimenter only needs to stand still in the designated position to extract the glass cleaner stored in the multiple refrigerators 9 in an orderly manner and obtain the antifreeze test results of the glass cleaner without the experimenter having to walk back and forth.

[0025] The three connecting rings 5 ​​installed on the insulating block 4 are connected to the power supply plug 2, so that the city power supply can be conducted to the connecting rings 5 ​​along the power supply plug 2. The connecting rings 5 ​​then conduct the power to the power socket 8. The power socket 8 can supply power to multiple refrigerators 9, so that the rotation of the tray 6 will not affect the power supply of the refrigerators 9.

[0026] The base 1 is fixed with an insulating protective shell 10. The insulating protective shell 10 is sleeved on the outside of the carrier column 3 and the insulating block 4. It will not affect the normal rotation of the carrier column 3. The power supply plug 2 is fixedly installed on the insulating protective shell 10. The purpose of the insulating protective shell 10 is to wrap the power supply plug 2 and the three contact rings 5 ​​to prevent dust from entering and to avoid accidental contact between the power supply plug 2 and the contact rings 5.

[0027] The drive assembly includes a drive motor 11, which is mounted on the base 1. A second gear 12 is fixed to the output shaft of the drive motor 11. The second gear 12 meshes with the first gear 7. The drive motor 11 drives the second gear 12 to rotate. Since the second gear 12 meshes with the first gear 7, the rotating second gear 12 can drive the first gear 7 to rotate, thereby driving the column 3 and the support plate 6 to rotate.

[0028] The base 1 has multiple columns 13 fixed on its upper surface. The columns 13 are arranged in a circular array, and the top of each column 13 is fitted with a ball bearing 14. The ball bearing 14 can rotate freely at the top of the column 13. The lower surface of the support plate 6 has an annular groove 15. The ball bearing 14 fits tightly against the inner wall of the annular groove 15. The columns 13 and the ball bearing 14 can help support the support plate 6 and share the force of the support column 3.

[0029] The base 1 has a carrier plate 16 fixed to its periphery, a support rod 17 fixed to the top of the carrier plate 16, and a supplementary light 18 installed at the top of the support rod 17. The carrier plate 16 supports the glass water container, and the supplementary light 18 makes it easier for the experimenters to see the results of the glass water antifreeze test more clearly.

[0030] Working principle of this utility model:

[0031] The experimenters placed the glassware containing glass cleaner in an orderly manner on the carrier plate 16, adjusted the cooling temperature of multiple refrigerators 9 so that the cooling temperature of multiple refrigerators 9 decreased in a gradient, and activated the drive motor 11 to drive the second gear 12 to rotate intermittently. The second gear 12 meshed with the first gear 7, so it could drive the first gear 7 to rotate intermittently. The first gear 7 drove the carrier column 3 and the support plate 6 to rotate, so that the multiple refrigerators 9 held on the support plate 6 changed positions intermittently. In this way, it was convenient for the experimenters to place the glassware containing glass cleaner into the multiple refrigerators 9 in an orderly manner.

[0032] After the glass cleaner is frozen in multiple refrigerators 9 for a period of time, the drive motor 11 is activated again to drive the second gear 12 to rotate intermittently, changing the position of the multiple refrigerators 9. The experimenter can take out the glass cleaner from the multiple refrigerators 9 one by one and place it on the carrier plate 16. With the supplementary light 18 turned on, the experimenter can clearly observe the antifreeze test results of the glass cleaner under different temperature gradients.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
