Description

Technical Field

[0001] This utility model relates to the field of antifreeze testing technology, and in particular to an antifreeze freezing point testing device. Background Technology

[0002] Antifreeze is a type of antifreeze with special additives, widely used in the antifreeze systems of various engines such as automobiles, diesel locomotives, and tractors. It is mainly composed of antifreeze agents, corrosion inhibitors, defoamers, and colorants, and functions to prevent freezing, prevent boiling, and resist corrosion. Antifreeze freezing point testing devices are professional equipment specifically used to determine the freezing point temperature of antifreeze. The common testing principle is to indirectly calculate its freezing point by measuring the density of the antifreeze, or to infer the freezing point by using the different refractive indices of light in the antifreeze, which correspond to different antifreeze components and concentrations.

[0003] While existing antifreeze freezing point testing devices are equipped with a suction mechanism at the front end to facilitate the extraction of sufficient antifreeze from the car's radiator, in actual use, antifreeze often undergoes stratification after long-term use or storage. This results in varying antifreeze concentrations at different depths and in different areas. Consequently, the freezing point detected by the suction mechanism on a local sample deviates from the actual freezing point of the entire antifreeze system.

[0004] Therefore, this utility model proposes an antifreeze freezing point detection device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an antifreeze freezing point detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an antifreeze freezing point detection device, comprising a detection component and a liquid suction component, wherein the liquid suction component comprises a liquid suction cylinder, one end of the liquid suction cylinder is threadedly connected to a rotary joint, the end of the rotary joint away from the liquid suction cylinder is threadedly connected to a hollow tube, the hollow tube being Z-shaped, and an outer cylinder being rotatably fitted to the circumferential side of the liquid suction cylinder.

[0007] Furthermore, a shaft lock is fixedly installed at one end of the outer cylinder, and the hollow tube passes through the shaft lock and the outer cylinder in sequence.

[0008] Furthermore, a first groove is provided on the peripheral side of the liquid suction cylinder, and a sliding plate is slidably fitted in the first groove.

[0009] Furthermore, a sliding rod is fixedly connected to one end of the slide plate, and an anti-slip groove is provided on the other end of the slide plate.

[0010] Furthermore, a spiral groove is provided on the inner circumferential side of the outer cylinder, and the spiral groove is slidably engaged with the slide rod.

[0011] Furthermore, a support plate is fixedly connected to one end of the liquid suction cylinder, and a second groove communicating with the first groove is opened on one side of the support plate. The support plate is fixedly connected to the detection component.

[0012] This utility model has the following beneficial effects: During testing, this invention involves pressing a finger onto the anti-slip groove and moving the sliding plate, causing it to slide within the first groove. The sliding plate moves the sliding rod in the same direction, and as the rod moves, it slides along the spiral direction of the spiral groove, causing the outer cylinder to rotate. The outer cylinder, in turn, rotates the hollow tube via the locking shaft, thus agitating the cryo-liquid within the container and ensuring uniform distribution of the substances. This guarantees good uniformity of the sample drawn by the suction cylinder and effectively reduces testing errors. Attached Figure Description

[0015] Figures 1 to 5 As shown, an antifreeze freezing point detection device is disclosed, comprising a detection component 1 (the detection component 1 consists of a cover plate, a prism, a lens tube and an eyepiece, which is prior art and will not be described in detail here) and a liquid absorption component 2; Specifically, the liquid suction assembly 2 includes a liquid suction cylinder 3 (the liquid suction principle of the liquid suction cylinder 3 is mainly based on atmospheric pressure difference and its internal piston movement, which is existing technology and will not be elaborated here). One end of the liquid suction cylinder 3 is threadedly connected to a rotary joint 4, and the end of the rotary joint 4 away from the liquid suction cylinder 3 is threadedly connected to a hollow tube 5. The rotary joint 4 is structurally divided into a stator and a rotor. Its stator is fixedly connected to the liquid suction cylinder 3, and the rotor of the rotary joint 4 is connected to the end of the hollow tube 5 by a threaded connection. In this way, when the hollow tube 5 rotates, only the rotor will rotate with the hollow tube 5, while the liquid suction cylinder 3 is kept stable by the stationary stator. At the same time, the liquid suction cylinder 3 can draw antifreeze from the container through the hollow tube 5.

[0016] The hollow tube 5 is Z-shaped, and the outer cylinder 6 is rotatably fitted around the side of the suction cylinder 3. A locking device 14 is fixedly installed at one end of the outer cylinder 6. The hollow tube 5 passes through the locking device 14 and the outer cylinder 6 in sequence. The locking device 14 is a bolt-type locking mechanism. By tightening the bolt, the internal parts of the locking device 14 are tightly fitted with the hollow tube 5, thereby fixing the hollow tube 5 and the outer cylinder 6. In this way, when the outer cylinder 6 rotates, the hollow tube 5 will also rotate.

[0017] Furthermore, the aspiration cylinder 3 has a first groove 7 on its circumference, and a slide plate 8 is slidably fitted inside the first groove 7. A slide rod 9 is fixedly connected to one end of the slide plate 8, and an anti-slip groove 10 is provided on the other end of the slide plate 8. The anti-slip groove 10 increases the friction between the finger and the slide plate 8. A spiral groove 11 is provided on the inner circumference of the outer cylinder 6, and the spiral groove 11 is slidably fitted with the slide rod 9. In order to ensure that the sample characteristics of each local area are the same, the finger can be pressed on the anti-slip groove 10 and the slide plate 8 can be moved to make the slide plate 8 slide in the first groove 7. The slide plate 8 drives the slide rod 9 to move in the same direction. While the slide rod 9 moves, it will slide along the spiral direction of the spiral groove 11, thereby causing the outer cylinder 6 to rotate. The outer cylinder 6 will drive the hollow tube 5 to rotate through the shaft locking device 14, so that the hollow tube 5 stirs the cryo-liquid in the container, making the substances in it evenly distributed and ensuring that the collected sample has good uniformity.

[0018] One end of the suction cylinder 3 is fixedly connected to a support plate 12. A second slide groove 13 communicating with the first slide groove 7 is opened on one side of the support plate 12. The support plate 12 is fixedly connected to the detection component 1 to provide support for the suction component 2.

[0019] The operation process in this embodiment is as follows: When drawing antifreeze from the car's water tank, the antifreeze in the water tank should be stirred first. That is, first insert the hollow tube 5 into the antifreeze in the water tank, then press your finger on the anti-slip groove 10 and move the sliding plate 8 so that the sliding plate 8 slides in the first sliding groove 7. The sliding plate 8 drives the sliding rod 9 to move in the same direction. While the sliding rod 9 moves, it will slide along the spiral direction of the spiral groove 11, thereby causing the outer cylinder 6 to rotate. The outer cylinder 6 will drive the hollow tube 5 to rotate through the locking shaft 14, thereby stirring the antifreeze in the container through the hollow tube 5. After stirring, the antifreeze in the car's water tank is drawn into the suction tube 3 through the hollow tube 5. Then, the cover plate at the front end of the detection component 1 is opened, and the antifreeze sample in the suction tube 3 is dripped onto the surface of the prism. The amount of dripping should be just enough to cover the surface of the prism. The cover plate is carefully closed to ensure that the cover plate and the prism are in close contact, so that the antifreeze forms a uniform thin layer between the prism and the cover plate. Observe through the eyepiece, and at the same time slowly rotate the adjustment knob on the instrument until a clear light-dark boundary line appears in the field of view. Read the freezing point value of the antifreeze according to the indication on the instrument's scale or display screen.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
