DETAILED DESCRIPTION

[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art belong to the protection scope of the present application.

[0022] As shown in the figure, Figures 1 to 7 The heat insulation device for gasoline engine is installed in front of the heat dissipation outlet 7-1 of the gasoline engine 7, and comprises a hollow box 1, a first bottom plate 2, a connecting bracket 3, a first connecting bolt 4, and a second connecting bolt 6. The hollow box 1 is internally provided with a heat insulation cavity. One end of the connecting bracket 3 is clamped between the hollow box 1 and the first bottom plate 2, and the hollow box 1, the connecting bracket 3 and the bottom plate are connected together through the first connecting bolt 4. The other end of the connecting bracket 3 is connected with the gasoline engine through the second connecting bolt 6.

[0023] In the present application, the heat insulation device is installed on the heat dissipation outlet of the gasoline engine, the hollow box 1 is arranged on the heat insulation device, the hollow box 1 is internally provided with a heat insulation cavity, the heat insulation cavity is filled with air, the air is a poor conductor of heat, the heat insulation cavity in the hollow box 1 enables the heat insulation device to have good heat insulation effect, and the hollow box 1 has a large thickness. The existence of the hollow box 1 plays a certain repelling role on personnel, so that personnel cannot approach the heat dissipation outlet of the gasoline engine. Even if the personnel touch the surface of the heat insulation device, there will still be a certain distance between the skin of the personnel and the heat dissipation outlet of the gasoline engine at this time. The existence of the distance ensures that the personnel will not be scalded by hot air, thereby achieving good heat insulation effect. One end of the connecting bracket 3 is clamped between the hollow box 1 and the bottom plate. This arrangement mode realizes the connection between the connecting bracket 3 and the hollow box 1 and the first bottom plate 2 on the one hand, and on the other hand, since the connecting bracket 3 is located between the hollow box 1 and the first bottom plate 2, a certain interval distance is formed between the hollow box 1 and the first bottom plate 2. The existence of the interval distance reduces the heat conduction efficiency between the first bottom plate 2 and the hollow box 1, thereby avoiding that the surface temperature of the hollow box 1 is too high. In this way, even if the personnel come into contact with the surface of the hollow box 1, the personnel will not be scalded.

The connecting bracket 3 is provided with a third bolt through hole 3-1a, and the first bottom plate 2 is provided with a fourth bolt through hole 2-1. The connecting bolt passes through the first bolt through hole 1-1a, the second bolt through hole 1-2a, the third bolt through hole 3-1a and the fourth bolt through hole 2-1 at the same time. The box body 1-1, the second bottom plate 1-2, the connecting bracket 3 and the first bottom plate 2 are fastened and connected together to form an integral whole through the first connecting bolt 4.
