Description

Technical Field

[0001] This utility model relates to the field of automotive oil plug technology, specifically to an automotive oil plug sealing performance testing device. Background Technology

[0002] In daily use, the oil plug's sealing performance is highly demanding, requiring the oil plug cover to have excellent sealing properties. The oil plug is sealed using a sealing rubber ring or paper gasket. The function of the oil plug cover is solely to ensure the reliability of the oil plug's seal. However, due to the inherent instability of sealing rubber rings or paper gaskets, leakage problems can easily occur. Therefore, in practical applications, multiple sensors are used to detect the oil plug's sealing performance, but the detection results are not intuitive enough. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automotive oil plug sealing performance testing device, which has the advantage of being able to easily test the sealing performance of oil plugs. It solves the problem that existing technologies use multiple sensors to test the sealing performance of oil plugs, but the test results are not intuitive enough.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An automotive oil plug sealing performance testing device includes an oil plug body for testing and a base plate for supporting the entire device. A connecting ring for easy airtightness testing is installed on the oil plug body. A connecting tube capable of vertical directional movement is installed at the bottom of the connecting ring. A fixing rod is detachably installed on the top of the base plate. A rubber piston that is in close contact with the inner wall of the connecting tube is installed on the top of the fixing rod. The connecting tube is made of transparent material and has scale lines on the outside to reflect the displacement changes of the internal rubber piston. A pressure sensor is embedded inside the connecting tube to reflect changes in the internal pressure value.

[0005] Preferably, a receiving container is fixedly connected to the outside of the connecting ring, and the receiving container can hold clean water.

[0006] Preferably, two electric telescopic rods are installed on the top of the base plate, and fixed plates are fixedly connected to the movable ends of the two electric telescopic rods. Two connecting plates are fixedly connected to the connecting pipe, and the two connecting plates and the two fixed plates are connected by bolts.

[0007] Preferably, the two electric telescopic rods are electrically connected to an external control switch for synchronous control of the two electric telescopic rods.

[0008] Preferably, the pressure sensor is electrically connected to an external display to reflect the changes in the internal pressure curve during the compression of the rubber piston in real time.

[0009] Preferably, when the rubber piston moves relative to the connecting pipe, the sealing performance of the oil plug body can be visually determined by observing whether air bubbles are generated in the water in the receiving container.

[0010] By employing the above technical solution, this utility model provides an automotive oil plug sealing performance testing device, which has at least the following beneficial effects: 1. This utility model simplifies the installation between the oil plug body and the connecting ring. Two electric telescopic rods drive the connecting pipe and the rubber piston to move in opposite directions, allowing the pressure sensor to detect the internal air pressure. If the air pressure tends to be stable, it indicates that the oil plug body has good sealing performance; otherwise, it proves that the oil plug body has insufficient sealing performance. At the same time, the displacement value of the rubber piston can be further observed through the scale line, so as to intuitively obtain the sealing effect of the piston body.

[0011] 2. This utility model allows for a more direct and visual inspection of the sealing performance of the oil plug body by setting up a receiving container. By adding clean water into the receiving container, when the electric telescopic rod drives the connecting pipe and the rubber piston to move relative to each other, it is possible to observe whether there are air bubbles at the oil plug body, thereby further determining the sealing performance of the piston.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The following describes, with reference to the accompanying drawings, some embodiments of an automotive oil plug sealing performance testing device provided by this utility model.

[0016] Example 1: To facilitate the testing of the sealing performance of the oil plug body 1, combined with Figures 1-4 As shown, an automotive oil plug sealing performance testing device is proposed. The device uses an oil plug body 1 for testing its sealing performance and a base plate 2 for supporting the entire device. A connecting ring 9 is installed on the oil plug body 1. The installation of the oil plug body 1 via the connecting ring 9 facilitates airtightness testing.

[0017] A vertically movable connecting pipe 4 is installed at the bottom of the connecting ring 9, and a fixing rod 3 is detachably installed at the top of the base plate 2. A rubber piston 11 that is in close contact with the inner wall of the connecting pipe 4 is installed at the top of the fixing rod 3. The internal pressure change is detected by the relative movement of the connecting pipe 4 and the rubber piston 11. The connecting pipe 4 is made of transparent material and has scale lines 5 on the outside to reflect the displacement change of the internal rubber piston 11. A pressure sensor 12 is embedded inside the connecting pipe 4 to reflect the internal pressure value change.

[0018] By installing and connecting the oil plug body 1 to the connecting ring 9, the connecting pipe 4 and the rubber piston 11 are moved towards each other. The initial and final positions of the rubber piston 11 are observed and compared with the scale line 5 to confirm the internal pressure environment. The pressure sensor 12 reflects the internal pressure changes in real time, thereby judging the overall sealing effect so as to know the sealing performance of the rubber piston 11.

[0019] To enable the connecting pipe 4 and the rubber piston 11 to move easily towards each other, two electric telescopic rods 6 are installed on the top of the base plate 2. The movable ends of the two electric telescopic rods 6 are fixedly connected to the fixing plates 7. Two connecting plates 8 are fixedly connected to the connecting pipe 4. The two connecting plates 8 and the two fixing plates 7 are connected by bolts. The two electric telescopic rods 6 are electrically connected to an external control switch for synchronous control of the two electric telescopic rods 6. Thus, the connecting pipe 4 and the rubber piston 11 can move easily towards each other, which facilitates detection.

[0020] To easily obtain the internal pressure change curve, the pressure sensor 12 is electrically connected to an external display to reflect the changes in the internal pressure curve during the compression of the rubber piston 11 in real time.

[0021] Example 2: Based on Example 1, the technical solution proposed in Example 1 is used to solve the problem that in the prior art, due to the certain stability of the use of sealing rubber rings or paper gaskets, leakage is easy to occur. Therefore, in practical applications, multiple sensors are used to detect the sealing performance of the oil plug, but the detection results are not intuitive enough. However, in order to further detect the sealing effect of the oil plug body 1, the detection needs to be further strengthened.

[0022] To further enhance the sealing performance of the oil plug body 1, combined with Figures 1-4 As shown, a receiving container 10 is fixedly connected to the outside of the connecting ring 9. Water can be placed in the receiving container 10. When the rubber piston 11 moves relative to the connecting pipe 4, it can be observed whether air bubbles are generated in the water in the receiving container 10. If air bubbles are generated, it indicates that the oil plug body 1 is not sealed properly, which can be used to further intuitively determine the sealing performance of the oil plug body 1.
