[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] Please see Figure 1-3 This utility model provides a technical solution: In this technical solution, a PVC oil resistance testing device includes an oil storage tank 1 and a cover 2. The cover 2 is placed over the upper opening of the oil storage tank 1. An electric control push rod 3 is installed on the upper wall of the cover 2. The output end of the electric control push rod 3 passes through the lower wall of the cover 2 and is installed with a placement basket 4. The external PVC item to be tested is placed in the placement basket 4. A rotating shaft 5 is inserted into the side wall of the placement basket 4. The two ends of the rotating shaft 5 pass through the left and right side walls of the placement basket 4 respectively. A stirring rod 6 is installed on the outside of the rotating shaft 5. The stirring rod 6 is set inside the placement basket 4. An impeller 7 is installed on the outside of one end of the rotating shaft 5. The impeller 7 is set on the outside of the placement basket 4. In this technical solution, the electrically controlled push rod 3 can drive the placement basket 4 to move up and down inside the oil storage tank 1, realizing the immersion and removal of the PVC item to be tested. At the same time, when the placement basket 4 moves in the oil, the oil will impact the impeller 7, drive the rotating shaft 5 to rotate, and then make the stirring rod 6 rotate inside the placement basket 4, which will play a stirring role in the oil, so that all parts of the PVC item to be tested can be evenly contacted with the oil, ensuring the accuracy of the test.

[0016] In some technical solutions, a cover 8 is fastened to the upper end of the basket 4, and locking plates 9 are installed on both the front and rear sides of the cover 8. The locking plates 9 can fix the position of the cover 8.

[0017] In this technical solution, the cover 8 can seal the upper end of the placement basket 4 to prevent the PVC items to be tested from falling out of the placement basket 4 during the movement of the placement basket 4 or the stirring of the oil, while the locking plate 9 can effectively fix the position of the cover 8 to prevent the cover 8 from being opened accidentally, thus enhancing the stability of the device during use. In this article, the locking plate 9 is made of plastic, which can be slightly deformed when it is bent, so that its positioning pin 10 can be inserted into the through hole 92; In this article, the placement basket 4 is made of woven wire mesh, which allows the oil to enter the placement basket 4 and fully contact the PVC item to be tested; In this article, the pin 12 is made of iron wire. After being inserted into the hole 11, the two ends of the pin 12 can be bent to prevent the plate 91 from detaching from the positioning pin 10.

[0018] In some technical solutions, the locking plate 9 includes a plate body 91 and a through hole 92. The plate body 91 has an L-shaped cross section. One end of the plate body 91 is installed on the side wall of the cover 8, and the other end of the plate body 91 has a through hole 92. A positioning pin 10 is installed on the side wall of the basket 4, and the positioning pin 10 can be inserted into the through hole 92.

[0019] In this technical solution, the L-shaped plate 91 is designed to fit well against the side walls of the cover 8 and the placement basket 4. When the positioning pin 10 is inserted into the through hole 92, the locking plate 9 can be connected to the placement basket 4, thereby fixing the cover 8. This fixing method is simple in structure, convenient to operate, and facilitates quick opening and closing of the cover 8.

[0020] In some technical solutions, the positioning pin 10 has a hole 11 at the end away from the placement basket 4, and a pin 12 is inserted into the hole 11 to block the plate 91.

[0021] In this technical solution, after the pin 12 is inserted into the hole 11, it can block the plate 91 and prevent the plate 91 from falling off the positioning pin 10. This further strengthens the fixing effect of the locking plate 9 on the cover 8, and prevents the cover 8 from loosening due to vibration or other reasons during the operation of the device, ensuring that the PVC item to be tested is always in the placement basket 4.

[0022] In some technical solutions, the upper wall of the cover 2 is provided with a through groove 13, and a transparent glass 14 is installed in the through groove 13.

[0023] In this technical solution, the transparent glass 14 allows the operator to clearly observe the testing status of the PVC items to be tested inside the oil storage tank 1 without opening the cover 2, including the state of the items and changes in the oil, so as to facilitate timely monitoring of the testing progress and detection of abnormalities.

[0024] In some technical solutions, lifting rings 15 are installed on both the left and right sides of the upper wall of the cover 2, and the lifting rings 15 can be connected to the hooks of an external crane.

[0025] In this technical solution, when it is necessary to move the cover 2, the hook of the external crane can be connected to the lifting ring 15, and the cover 2 can be easily lifted and moved by the crane, which reduces the labor intensity of manually handling the cover 2. It is particularly convenient and efficient when the cover 2 is large or heavy.

[0026] In some technical solutions, the lower end of the side wall of the oil storage tank 1 is inserted into one end of the oil drain pipe 16, and the other end of the oil drain pipe 16 is equipped with a valve 17.

[0027] In this technical solution, when the test is completed or the oil needs to be replaced, the valve 17 is opened and the oil in the oil storage tank 1 can be discharged through the oil drain pipe 16, which facilitates the treatment or replacement of the oil without the need to empty the oil storage tank 1, making the operation simple and convenient.

[0028] Working principle: When using this PVC oil resistance tester, first place the PVC item to be tested into the placement basket 4, close the cover 8, connect the cover 8 to the placement basket 4 through the plate 91 on the locking plate 9, insert the positioning pin 10 into the through hole 92, and then insert the pin 12 into the hole 11 of the positioning pin 10 to fix the cover 8. Then, using the lifting ring 15, the cap 2 is hoisted to the upper opening of the oil storage tank 1 and closed. The electric control push rod 3 is activated, and its output end drives the placement basket 4 to move up and down in the oil. During the up and down movement of the placement basket 4, the oil impacts the impeller 7, causing the rotating shaft 5 to rotate, which in turn drives the stirring rod 6 to rotate inside the placement basket 4, stirring the PVC items and oil inside, ensuring that the PVC items to be tested are evenly soaked. At the same time, the operator can observe the test process through the transparent glass 14 on the cap 2.
