[0029] As Figure 1 shown, manually install fuel filler pipe to simulation mechanism, realize the intercommunication of fuel filler pipe and simulation mechanism, pour into appropriate gasoline in oil tank 1, start water pump 201, water pump 201 will gasoline in oil tank 1 be sent into fuel filler pipe through connecting hose 202, external thread pipe 601 and connector 602, then gasoline flows back to oil tank 1 through connecting pipe 203, whether there is gasoline outside fuel filler pipe is observed, no is eligible, otherwise unqualified.
[0030] Meanwhile when staff needs to check different specifications of fuel filler pipe, fuel filler pipe is taken off from simulation mechanism from connecting mechanism, replace fuel filler pipe, manually cone-shaped connector 602 and different diameter fuel filler port end are pasted, can low cost fast check different specifications of fuel filler pipe.
[0031] Among them, the model of water pump 201 can select 1K0919051MS, staff can also select different models according to actual market demand.Water pump 201 is electrically connected with external power supply, and since water pump 201 is the common knowledge of the person skilled in the art, the specific structure, switch mode and working principle are not described in detail.
[0032] Specifically, connecting mechanism includes connecting frame 603, connecting frame 603 is screw-connected outside external thread pipe 601, connecting frame 603 one end is installed with mounting bracket 604, and mounting bracket 604 is installed on fuel filler pipe.The mounting bracket 604 is installed to the cross plate at fuel filler port of fuel filler pipe, rotating external thread pipe 601, then external thread pipe 601 and connector 602 move to fuel filler port, realize the intercommunication of fuel filler pipe and connector 602, then do not need manual auxiliary simulation mechanism in testing process, improve the security of inspection to a certain extent.

Since there is a certain pressure in the fuel pipe during the refueling process, the worker closes the valve 204, and the water pump 201 continuously operates, so that the gasoline in the fuel pipe applies a certain pressure to the fuel pipe. The pressure environment that the fuel pipe may encounter during actual use can be simulated, so as to test whether the sealing performance of the fuel pipe during use meets the requirements. The application of pressure can also improve the accuracy of the test. When a small leakage is difficult to detect, a certain pressure is applied, and the leakage amount is correspondingly increased, so that it is easier to be detected.
[0034] As shown in Figure 4 The outer wall of the connecting head 602 is provided with a sealing gasket 6021. The sealing gasket 6021 makes the connection between the connecting head 602 and the fuel port more tight, and avoids the gasoline flowing out from the gap between the connecting head 602 and the fuel port during the test as much as possible, so as to avoid the test personnel mistakenly thinking that the fuel pipe leaks, and affecting the test result.

[0038] As shown in Figure 5As shown, the oil storage tank 1 is provided with a second support seat 401, the bottom of the second support seat 401 is provided with a first moving assembly for moving the position of the second support seat 401, the two sides of the second support seat 401 are provided with a second limiting rod 402, the second limiting rod 402 is provided with a second clamping piece 403, the second support seat 401 is rotatably connected with a second bidirectional screw rod 404, the second bidirectional screw rod 404 is threadedly connected in the second clamping piece 403, one side of the second clamping piece 403 is provided with a second clamping block 405 matched with the oil filling pipe, and the second clamping piece 403 is provided with a second moving assembly for moving the second clamping block 405. By rotating the second bidirectional screw rod 404, the two groups of second clamping pieces 403 are close to each other under the cooperation of the second limiting rod 402, so that the oil filling pipe is fixed, and the connection between the oil filling pipe and the connector 602 during the test is more stable. And because the bending degree of the oil filling pipe is different, the worker can move the first clamping block 305 through the first moving assembly and the second moving assembly, so that the first clamping block 305 can fix the oil filling pipe more stably.
[0039] Specifically, as shown in the drawings, Figure 5 The first moving assembly comprises a first sliding block 4011, the first sliding block 4011 is installed at the bottom of the second support seat 401, and the oil storage tank 1 is provided with a first sliding groove 4012 matched with the first sliding block 4011.

The gasoline attached to the inner wall of the oil filling pipe after the inspection can avoid rusting of the oil filling pipe to a certain extent, which is beneficial to the preservation and storage of the oil filling pipe.
[0042] When the sealing performance of oil filling pipes of different specifications needs to be checked, the clamp 501 is unscrewed, the connector 602 and the oil filling port are separated, the oil filling pipe to be checked is installed on the simulation mechanism through the clamp 501 provided on the oil filling pipe, and the connector 602 is connected with the oil filling port manually, so that the purpose of checking the sealing performance of oil filling pipes of different specifications can be achieved.
