Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Example 1

As shown in Figures 1 to 6, a side door position-limiting and fixing mechanism for an engine guard includes a side door assembly 1, a side door fixing pin 2 and a side door fixing plate 4, and a limit pin 3 is provided inside the side door fixing plate 4; The side door assembly 1 includes a side door 11 and a handle 14. The side door 11 includes a door panel 111, a fixing block 113 fixed on the outside of the door panel and a limit plate 112. The bottom edge of the door panel 111 is provided with a pin hole that matches the side door fixing pin. 5. The limit plate 112 is provided with a limit hole 114 that cooperates with the limit pin 3, and the limit hole 114 is provided with a rubber sleeve 12. The setting of the rubber sleeve makes the cooperation between the limit shaft and the limit plate more closely and stable.

The side door fixing pin 2 is arranged on the bottom edge of the engine guard, and the side door fixing plate 4 is fixed on the side of the engine guard.

The handle 14 is L-shaped, and a screw hole 140 is provided at the bend of the handle 14 , and the bolt 13 passes through the screw hole 140 to install the handle 14 on the fixing block 113 . The diameter of the screw hole 140 is larger than that of the bolt 13 , and the handle 14 can freely rotate between the fixing block 113 and the bolt 13 .

When closing the side door assembly 1, rotate the handle 14 and lay it flat, as shown in Figure 1, the pin hole 5 on the bottom edge of the door panel 111 is aligned with the side door fixing pin 2, and then the door panel is pressed down, and the limit pin 3 passes through the rubber sleeve 12 , then release the handle 14, only when there is no other external force under the action of gravity, the long side of the L-shaped handle hangs down naturally, in the state shown in Figure 2, and the side door assembly 1 is limited and fixed by the side door fixing plate 4.
