Detailed description of the invention
As shown in Figure 1 to Figure 3, the mounting structure of the built-in part of the utility model plastic fuel tank comprises built-in part mounting bracket 2 and the welding base 1 of fixing built-in part, the bottom surface of welding base 1 is welded in plastic fuel tank inwall, the welding end face of base 1 and the bracket base 2a phase clamping of built-in part mounting bracket 2.
As shown in Figure 4, Figure 5, the end face center of welding base 1 is provided with along the axis of welding base 1 central boss 1a protruding upward, and central boss 1a is up-small and down-big truncated cone-shaped.The end face of welding base 1 is also provided with arc-shaped slot 1b, and arc-shaped slot 1b extends along by the circumference welded centered by base axis.
As shown in Figure 6 to 8, the bottom center of bracket base 2a is provided with bracket base centre hole 2a1, bracket base centre hole 2a1 is suitable with the central boss 1a shape size welding base 1, and the bottom surface of bracket base 2a is also provided with corresponding with arc-shaped slot 1b and can the arc-shaped claws 2a2 of clamping mutually.Arc-shaped slot 1b and arc-shaped claws 2a2 centered by the axis welding base 1 asymmetric be provided with two right.Unsymmetrical arrangement can play installation direction error-disable function.
The upper surface of bracket base 2a is provided with flange, and the edge of flange is provided with positive stop spring plate 2a3, and the free end of positive stop spring plate 2a3 stretches out formation opening downwards, and the opening direction of positive stop spring plate 2a3 is contrary with the opening direction of arc-shaped claws 2a2; The end face of welding base 1 is provided with positive stop 1c protruding upward, and when arc-shaped claws 2a2 and arc-shaped slot 1b clamping put in place, the open end of positive stop spring plate 2a3 withstands on the side of positive stop 1c.
It is two right that positive stop spring plate 2a3 and positive stop 1c is arranged with centered by the axis welding base 1, makes the combination of welding base 1 and built-in part mounting bracket 2 more reliable.
The side that positive stop 1c and the root of positive stop spring plate 2a3 first contact is provided with inclined-plane 1c1.Positive stop spring plate 2a3 is along sliding on inclined-plane 1c1, and when crossing positive stop 1c, the open end of positive stop spring plate 2a3 ejects and realizes non-return, and inclined-plane 1c1 makes sliding of positive stop spring plate 2a3 light more smoothly.
During installation, first welding base 1 is welded on fuel tank inwall, then built-in part is fixed on built-in part mounting bracket 2, again built-in part mounting bracket 2 is sent into fuel tank inner chamber from oil pump mouth, the bracket base 2a of built-in part mounting bracket 2 is connected to the combination namely welding base 1 achieving both.
Built-in part mounting bracket 2 with the clamping process of welding base 1 is, bracket base centre hole 2a1 is sleeved on the central boss 1a of welding base 1, achieve built-in part mounting bracket 2 and the centralized positioning of welding base 1, then built-in part mounting bracket 2 is rotated a certain angle, along with bracket base 2a rotates on the end face of welding base 1, first the arc-shaped claws 2a2 of bracket base 2a falls into the arc-shaped slot 1b of welding base 1, continue rotational support base 2a, the open end of arc-shaped claws 2a2 inserts the end of arc-shaped slot 1b, and both put in place in clamping.When bracket base 2a rotates, positive stop spring plate 2a3 is along sliding on the inclined-plane 1c1 of positive stop 1c, and when crossing positive stop 1c, the open end of positive stop spring plate 2a3 ejects and realizes non-return.When arc-shaped claws 2a2 and arc-shaped slot 1b clamping put in place, the open end of positive stop spring plate 2a3 just in time ejects the side withstanding on positive stop 1c, because the opening direction of positive stop spring plate 2a3 is contrary with the opening direction of arc-shaped claws 2a2, positive stop spring plate 2a3 and arc-shaped claws 2a2 forms interlocking when clamping simultaneously puts in place, built-in part mounting bracket 2 is firmly fixed on welding base 1, and can not gets loose.
The foregoing is only the better possible embodiments of the utility model, non-ly therefore limit to scope of patent protection of the present utility model.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
