The fuel tank is an essential part of the automobile, and its quality directly affects the safety of automobile use. During the production process, fuel tanks need to undergo airtightness testing to check for potential safety hazards.

[0003] The detection device is inconvenient to adjust the height of the oil tank during use, making it difficult to detect oil tanks of different sizes. Furthermore, directly immersing the oil tank in water for testing requires time to observe bubbles, resulting in a slow detection rate and affecting the usability of the detection device.

[0004] Therefore, there is an urgent need for a fuel tank airtightness testing device to solve the problem that testing devices are inconvenient for testing fuel tanks of different sizes. Utility Model Content

The outer surface of the support rod is slidably connected to the inner side of the partition.

[0008] By adjusting the height of the threaded rod, the threaded rod drives the support plate to move up and down via the support rod. The support plate then drives the oil tank to move up and down. When the support plate drives the oil tank to move down, it is submerged in water, thus allowing the detection device to detect oil tanks of different sizes.

[0009] Preferably, the outer surface of the threaded sleeve is rotatably connected to a fixing plate via a bearing, and the two ends of the fixing plate are welded to the inside of the testing box.

[0010] Preferably, a guide sleeve is fixedly connected to the top of the fixing plate by screws, a guide rod is slidably connected to the top of the guide sleeve, and the top of the guide rod is fixedly connected to the bottom of the support plate by screws.

[0011] Preferably, the outer surface of the guide rod is slidably connected to the inner side of the partition.

[0012] Preferably, the ventilation mechanism includes an air pump, a hose, and a plug. The air pump is installed on one side of the test box, and the air pump is connected to the plug through the hose. The hose is installed on a plate on one side of the test box.

The other end of the threaded rod 113 is welded to the bottom of the support rod 114. The top of the support rod 114 is fixedly connected to the support plate 115 by screws. The outer surface of the support rod 114 is slidably connected to the inner side of the partition 2. The outer surface of the threaded sleeve 112 is rotatably connected to a fixing plate 116 through a bearing. Both ends of the fixing plate 116 are welded to the inner side of the test box 1. The top of the fixing plate 116 is fixedly connected to a guide sleeve 117 by screws. The top of the guide sleeve 117 is slidably connected to a guide rod 118. The top of the guide rod 118 is fixedly connected to the bottom of the support plate 115 by screws. The outer surface of the guide rod 118 is slidably connected to the inner side of the partition 2.

[0027] With the above technical solution, when the oil tank is placed on top of the support plate 115, the drive motor 111 is started. The drive motor 111 drives the threaded sleeve 112 to rotate. When the threaded sleeve 112 rotates, it drives the threaded rod 113 to move up and down. By adjusting the height of the threaded rod 113, the threaded rod 113 drives the support plate 115 to move up and down through the support rod 114. The support plate 115 drives the oil tank to move up and down. When the support plate 115 drives the oil tank to move down, it is submerged in water, so that the detection device can detect oil tanks of different sizes. The threaded sleeve 112 rotates inside the fixed plate 116. When the support plate 115 moves up and down, the support plate 115 drives the guide rod 118 to slide inside the guide sleeve 117.

[0028] Specifically, the ventilation mechanism includes an air pump 211, a hose 212, and a plug 213. The air pump 211 is installed on one side of the test box 1.

[0029] With the above technical solution, the fuel tank is sealed and an air inlet adapted to plug 213 is reserved. Plug 213 is connected to the fuel tank. When air pump 211 is started, air pump 211 introduces air into the fuel tank through hose 212 and plug 213. When the fuel tank is submerged in water, bubbles can be observed to determine the airtightness of the fuel tank.

[0030] Specifically, the drying mechanism includes a fixed frame 311, a hot air blower 312, a connecting pipe 313, and an exhaust box 314. The fixed frame 311 is fixedly connected to the back of the test box 1 by screws. The hot air blower 312 is installed on the back of the test box 1. The hot air blower 312 is connected to the exhaust box 314 through the connecting pipe 313. The exhaust box 314 has several sets of exhaust holes 315 on its front.

[0031] With the above technical solution, after the oil tank is inspected, the hot air blower 312 is started. The hot air blown out by the hot air blower 312 enters the air outlet box 314 through the connecting pipe 313. The hot air is sprayed out from the air outlet 315, thereby drying the oil tank and making it easy to recycle.

[0032] In use, by adjusting the height of the threaded rod 113, the threaded rod 113 drives the support plate 115 to move up and down through the support rod 114. The support plate 115 drives the oil tank to move up and down. When the support plate 115 drives the oil tank to move down, it is submerged in water, so that the detection device can detect oil tanks of different sizes.
