[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 3 As shown:

[0020] Example 1: This utility model provides an oil casing sealing test device, including a main body 1. A control panel 10 is fixedly installed at the middle position of one end of the front of the main body 1. A test component 2 is installed at the middle position of the top of the main body 1. Airbags 23 are symmetrically installed on both sides inside the main body 1. An exhaust pipe 27 is connected to the middle position of the top of the airbags 23 and extends to the outside of the main body 1. A sealing cover 22 is provided on the outside of the exhaust pipe 27. An installation chamber 26 is installed at the middle position of the bottom of the main body 1. A second air pump 25 is installed at the bottom of the installation chamber 26. The output end of the second air pump 25 is connected to a second air pipe 24. The two ends of the second air pipe 24 away from the second air pump 25 are respectively connected to the inside of the two sets of airbags 23. Moving components 3 are symmetrically installed on the top and bottom of both sides of the main body 1.

[0021] Preferably, a first air pump 21 is installed on the inner top of the detection component 2, the output end of the first air pump 21 is connected to a first air pipe 20, and the end of the first air pipe 20 away from the first air pump 21 extends into the interior of the main body 1.

[0022] Preferably, handles are symmetrically fixedly installed on the top and bottom of one side of the front of the main body 1, and anti-slip texture is provided in the middle of the outer side of the handle. The handle makes it easy for the operator to hold the device, and the anti-slip texture makes it more convenient for the operator to hold it.

[0023] Preferably, the installation chamber 26 has symmetrical heat dissipation holes at both ends, and a dustproof net is provided on the inner side of the heat dissipation holes. The heat generated by the second air pump 25 during use can be discharged through the heat dissipation holes, and the dustproof net can block dust.

[0024] Preferably, the airbag 23 is made of rubber and has a circular ring shape. The rubber material of the airbag 23 allows it to be sealed when it is attached to the oil casing, and the circular ring structure allows the device to be properly fitted onto the outside of the oil casing.

[0025] As can be seen from the above, when using the device, it is first placed on the outside of the oil casing to be tested. After the device is placed, the moving component 3 is used to move the device to the position to be tested. After the movement is completed, the second air pump 25 is turned on. Then, the second air pump 25 inflates the air bag 23 through the second air pipe 24. After inflation, the air bag 23 is tightly fitted with the oil casing to be tested to form a sealed space. Then, the first air pump 21 is turned on to inflate the sealed space. The oil casing is tested by inflation, which allows the operator to obtain the test results more quickly, thereby improving the working efficiency of the device.

[0026] Example 2: This example is basically the same as the previous example, except that an electric push rod 32 is fixedly installed at a position where multiple sets of moving components 3 are far apart from each other. An installation block 33 is fixedly installed at the output end of the electric push rod 32. An installation groove 34 is fixedly installed on the side of the installation block 33 away from the main body 1. An installation frame 31 is fixedly installed on the inner side of the installation groove 34. An electric drive roller 30 is rotatably connected to the inner side of the installation frame 31.

[0027] As can be seen from the above, during the inspection, the device is first placed on the outside of the oil casing to be inspected. After placement, the electric push rod 32 is opened, and the electric push rod 32 drives the mounting groove 34 to move up and down, so that the mounting groove 34 drives the electric drive roller 30 to fit against the outside of the oil casing. After fitting, the electric drive roller 30 is opened, and the electric drive roller 30 drives the device to move. There is no need for the operator to manually move the device, which makes it more convenient for the operator to use.

[0028] Working principle: During testing, the device is first fitted onto the outside of the oil casing to be tested. After fitting, the electric push rod 32 is opened, which drives the mounting groove 34 to move up and down, causing the mounting groove 34 to drive the electric drive roller 30 to fit against the outside of the oil casing. After fitting, the electric drive roller 30 is opened, and the electric drive roller 30 drives the device to move, eliminating the need for manual movement by the operator, thus making it more convenient for the operator to use. After moving, the second air pump 25 is opened, and then the second air pump 25 inflates the air bag 23 through the second air pipe 24. After inflation, the air bag 23 fits tightly against the oil casing to be tested to form a sealed space. Then, the first air pump 21 is opened to inflate the sealed space. The oil casing is tested by inflation, allowing the operator to obtain the test results more quickly, thereby improving the working efficiency of the device.
