Description

Technical Field

[0001] This utility model relates to the field of antifreeze filling technology, and in particular to an auxiliary tool for filling antifreeze into automobiles. Background Technology

[0002] The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the car is parked in cold winter. Antifreeze is a coolant containing special additives and is mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as preventing freezing in winter, preventing boiling in summer, preventing scale buildup year-round, and preventing corrosion.

[0003] Antifreeze evaporates naturally under the high temperatures of the engine, causing the amount of antifreeze in a car to decrease as the car ages. To prevent damage due to low antifreeze levels, it's necessary to top up the antifreeze regularly. The traditional method of topping up antifreeze involves manually lifting the container and aligning it with the filler neck. This method often results in spillage due to inaccurate alignment, wasting antifreeze and potentially contaminating the vehicle, making it inefficient for adding antifreeze. Utility Model Content

[0004] The purpose of this application is to provide an auxiliary tool for adding antifreeze to automobiles, in order to solve the problem mentioned in the background art that the traditional method of adding antifreeze to automobiles involves manually picking up the container containing antifreeze and aligning it with the antifreeze filler neck to complete the antifreeze filling operation. This often results in antifreeze overflow due to the worker not accurately aligning the filler neck, leading to waste of antifreeze and causing some pollution to the automobile, thus being detrimental to the problem of adding antifreeze to automobiles.

[0005] To achieve the above objectives, this application provides the following technical solution: an auxiliary device for filling antifreeze in automobiles, comprising a supply assembly, a first stud mounted on the supply assembly, a first knob fixed to the top of the first stud, a carrier block rotatably connected to the bottom of the first stud via a bearing, a fixed cylinder fixed to the circumferential side of the carrier block, a telescopic plate slidably inserted into the open side of the fixed cylinder, a second stud threadedly connected to the fixed cylinder, a second knob fixed to the top of the second stud, and the second stud used for locking the fixed cylinder and the telescopic plate, an injection pipe fixedly inserted into the telescopic plate, a valve mounted on the injection pipe, a delivery pipe fixedly connected between the injection pipe and the supply assembly, the supply assembly for delivering antifreeze to the injection pipe, and a pressurizing assembly mounted on the supply assembly for pressurizing the supply assembly.

[0006] Furthermore, a limit rod is fixed on the telescopic plate, and a limit groove for sliding the limit rod is provided on the fixed cylinder.

[0007] Furthermore, the liquid supply assembly includes a liquid supply cylinder, the infusion tube is fixed to and communicates with the bottom of the liquid supply cylinder, a plurality of support columns are fixed to the outer wall of the liquid supply cylinder, a base is fixed to the bottom end of the plurality of support columns, a support plate is fixed to the upper surface of the base, the first stud is vertically inserted into the support plate and threadedly connected to the support plate, an electric push rod is installed on the support plate, a sealing cap is fixedly installed at the output end of the electric push rod, the sealing cap is located directly above the liquid supply cylinder, and the pressurization assembly is installed on the support plate.

[0008] Furthermore, the sealing cap is placed over the top of the liquid supply cylinder, and a sealing ring is installed at the joint between the sealing cap and the liquid supply cylinder.

[0009] Furthermore, the bottom of the base is equipped with several omnidirectional casters, and the upper surface of the base is provided with grooves.

[0010] Furthermore, the pressurization assembly includes an air pump, which is mounted on a support plate and has a filter screen installed at its air inlet. The air outlet of the air pump is fixedly connected to an air delivery pipe, and the sealing cap is fixedly sleeved on the outside of the air delivery pipe.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, by pulling outwards the telescopic plate, the combined length of the fixed cylinder and the telescopic plate is adjusted, and a simple lock is made with the second stud. The telescopic plate is rotated and the position of the injection pipe is moved with the help of several universal casters, so that the injection pipe is moved directly above the car antifreeze filling port. When the first knob is turned to drive the first stud to rotate, the fixed cylinder is held still, so that the first stud pushes the load block, the fixed cylinder, the telescopic plate and the injection pipe to move vertically downwards. In this way, the injection pipe can be inserted into the filling port, which facilitates the subsequent filling of antifreeze. This not only avoids the overflow of antifreeze during filling, but also eliminates the need for manual lifting during the antifreeze filling process, thus better meeting the needs of replenishing car antifreeze.

[0013] 2. In this utility model, an electric push rod is used to push the sealing cover down, so that the sealing cover covers the top of the liquid supply cylinder, thereby sealing the liquid supply cylinder. An air pump is used to pressurize the inside of the liquid supply cylinder, thereby increasing the air pressure inside the liquid supply cylinder. This allows the antifreeze to be delivered along the delivery pipe to the injection pipe, and the antifreeze can be discharged along the injection pipe, thus completing the work of adding antifreeze to the car.

[0020] 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.

[0021] Example: Reference Figure 1-4 The illustrated automotive antifreeze filling accessory includes a supply assembly with a first stud 1 mounted on it. A first knob 2 is fixed to the top of the first stud 1, and a carrier block 3 is rotatably connected to the bottom of the first stud 1 via a bearing. A fixing cylinder 4 is fixed to the circumferential side of the carrier block 3. A telescopic plate 5 is slidably inserted into the open side of the fixing cylinder 4. A limit rod 10 is fixed on the telescopic plate 5, and a limiting groove 11 is provided on the fixing cylinder 4 for sliding the limit rod 10. The limit rod 10 and the limiting groove 11 work together. To prevent the fixed cylinder 4 from completely separating from the telescopic plate 5, a second stud 6 is threaded onto the fixed cylinder 4. A second knob 7 is fixed to the top of the second stud 6, and the second stud 6 is used to lock the fixed cylinder 4 and the telescopic plate 5. An injection pipe 8 is fixedly inserted into the telescopic plate 5. A valve is installed on the injection pipe 8. An infusion pipe 9 is fixedly connected between the injection pipe 8 and the liquid supply assembly. The liquid supply assembly is used to deliver antifreeze to the injection pipe 8. A pressurization assembly is installed on the liquid supply assembly. The pressurization assembly is used to pressurize the liquid supply assembly.

[0022] By pulling the telescopic plate 5, adjust the combined length of the fixed cylinder 4 and the telescopic plate 5, and lock it simply with the second stud 6. Rotate the telescopic plate 5 and move the position of the injection pipe 8 with the help of multiple universal casters 18, so that the injection pipe 8 is moved directly above the antifreeze filling port of the car. When turning the first knob 2 to drive the first stud 1 to rotate, hold the fixed cylinder 4 and keep it still, so that the first stud 1 pushes the carrier block 3, the fixed cylinder 4, the telescopic plate 5 and the injection pipe 8 to move vertically downward. In this way, the injection pipe 8 can be inserted into the filling port, which is convenient for subsequent antifreeze filling.

[0023] The liquid supply assembly includes a liquid supply cylinder 12, with an infusion tube 9 fixed to and connected to the bottom of the liquid supply cylinder 12. Multiple support columns 13 are fixed to the outer wall of the liquid supply cylinder 12, and a base 14 is fixed to the bottom end of each support column 13. A support plate 15 is fixed to the upper surface of the base 14. A first stud 1 is vertically inserted into the support plate 15 and threadedly connected to the support plate 15. An electric push rod 16 is mounted on the support plate 15, and a sealing cap 17 is fixedly installed at the output end of the electric push rod 16. The sealing cap 17 is fastened... The sealing cap 17 is placed on top of the liquid supply cylinder 12, and a sealing ring is installed at the joint between the sealing cap 17 and the liquid supply cylinder 12. The sealing ring is used to ensure that the top of the liquid supply cylinder 12 can be better sealed when the sealing cap 17 covers the liquid supply cylinder 12. Multiple universal casters 18 are installed at the bottom of the base 14. A groove 19 is opened on the upper surface of the base 14. The groove 19 is opened to facilitate the placement of the antifreeze storage tank. The antifreeze in the antifreeze storage tank can be replenished into the liquid supply cylinder 12 for use in a timely manner.

[0024] The pressurization assembly includes an air pump 20, which is mounted on a support plate 15. The air pump 20 has a filter screen installed at its air inlet and an air supply pipe 21 is fixedly connected to its air outlet. A sealing cap 17 is fixedly sleeved on the outside of the air supply pipe 21.

[0025] The sealing cap 17 is pushed down by the electric push rod 16, so that the sealing cap 17 covers the top of the liquid supply cylinder 12, thereby sealing the liquid supply cylinder 12. The air pump 20 pressurizes the liquid supply cylinder 12, thereby increasing the air pressure inside the liquid supply cylinder 12. This increases the air pressure inside the liquid supply cylinder 12, allowing antifreeze to be delivered along the infusion pipe 9 to the injection pipe 8. The antifreeze can then be discharged along the injection pipe 8, completing the work of adding antifreeze to the car.

[0026] Working principle of this utility model:

[0027] In use, the electric push rod 16 is operated to move the sealing cap 17 upward, pouring the antifreeze from the antifreeze storage tank into the supply cylinder 12. Because the top of the supply cylinder 12 has a large opening and is located in an open area, it is much easier for workers to add antifreeze into the supply cylinder 12 than to add antifreeze directly into the car. After the supply cylinder 12 is full of antifreeze, the electric push rod 16 is operated to push the sealing cap 17 downward, so that the sealing cap 17 covers the top of the supply cylinder 12 and seals it. The antifreeze storage tank is placed in the groove 19 so that it can move with the supply cylinder 12, making it convenient to add antifreeze into the supply cylinder 12.

[0028] Using multiple omnidirectional casters 18, move the injection pipe 8 to a suitable position. Pull out the telescopic plate 5, adjust the combined length of the fixed cylinder 4 and the telescopic plate 5, and lock it simply with the second stud 6. Rotate the telescopic plate 5 to adjust the position of the injection pipe 8 so that the injection pipe 8 is directly above the car's antifreeze filling port. While turning the first knob 2 to rotate the first stud 1, the worker holds the fixed cylinder 4 and keeps it still, so that the first stud 1 pushes the injection pipe 8 vertically downward until the injection pipe 8 is inserted into the car's antifreeze filling port. Use the air pump 20 to pressurize the inside of the supply cylinder 12. After the air pressure inside the supply cylinder 12 increases, the antifreeze inside can enter the injection pipe 8 along the infusion pipe 9 and finally be added to the car along the injection pipe 8. Observe the amount of antifreeze added at any time. When the car's antifreeze is added to the appropriate position, close the valve on the injection pipe 8, turn the first knob 2 in reverse to move the injection pipe 8 upward, and remove the device to complete the car's antifreeze replenishment work.

[0029] 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.
