Embodiment 1
[0017] Such as figure 1 As shown, an oil tank for air leakage inspection includes a square hollow box 2 with an open upper end, and the box 2 has a cavity 4 for accommodating liquid. The fuel tank also includes a gas pipe fixing frame that can be erected on the upper end of the casing 2 . The trachea fixing frame includes a plate-shaped body 6 and four support plates 8 uniformly arranged on the circumference of the body 6 and extending laterally outward. The middle part of the body 6 is provided with a trachea fixing hole 12, and the free end of the support plate 8 is provided with a flange 14 vertically. wall.
[0018] When installing the trachea fixing frame, make the four support plates 8 perpendicular to the four sides of the box body 2 and place them on the upper end of the box body 2, and the flange 14 extends downward relative to the support plate 8, just close to the corresponding side of the box body 2 wall outside the wall. Since the four support plates 8 have fl...
Embodiment 2
[0022] Such as Figure 1-2 As shown, a fuel tank for air leakage inspection differs from Embodiment 1 in that: a support plate 8 is vertically provided with a block support seat 22, and the top end of the support seat 22 is provided with a groove. The bottom surface 24 of the groove is an arc-shaped curved surface vertically recessed to the support plate 8 . The rear end of the air pipe inserted into the air pipe fixing hole 12 can be erected in the groove of the support seat 22 to prevent the air pipe from shaking left and right under the influence of the air flow, stirring the oil and affecting the inspection results. The arc-shaped curved surface fits the shape of the circular trachea better and increases stability.
Embodiment 3
[0024] Such as figure 1 , 3 As shown, a fuel tank for air leakage inspection differs from Embodiment 2 in that: the support base 22 is provided with a hook 26 that can cooperate with the groove to form a closed loop, and one end of the hook 26 is axially connected to the support base 22 , the other end is provided with a fixed hook 28, and the fixed hook 28 can be movably connected with a fixed ring 32 provided on the support seat 22. During use, at first the crotch 26 is opened relative to the groove, the trachea is erected in the groove, and stretched into the fixing hole, then the crotch 26 is closed relative to the groove, the fixing hook 28 is connected with the fixing ring 32, and then firmly Lock the position of the trachea firmly and prevent the trachea from bouncing up and down.
