[0023] See also Figure 1-4 The utility model provides a technical solution: an easily disassembled engine hot air isolation baffle, comprising an engine 1 and a hot air isolation mechanism, a muffler 2 is fixedly installed on the top of the engine 1, a radiator 3 is arranged on the right side of the engine 1, a radiator bellows 4 is fixedly installed on the surface of the radiator 3, and a cooling fan 15 is installed inside the radiator bellows 4.

[0024] The power of the cooling fan 15 is provided by the power output shaft of the engine 1. The cooling fan 15 rotates and blows toward the surface of the heat sink inside the radiator 3 to achieve the purpose of rapid heat dissipation.

[0025] The hot air isolation mechanism includes a hot air isolation baffle 5, two connecting plates 6, two trapezoidal blocks 8, a trapezoidal fixing plate 10, a protrusion 11 and a spring 12. The hot air isolation baffle 5 is fixedly installed on the surface of the radiator bellows 4. The two connecting plates 6 are fixedly connected to the surface of the hot air isolation baffle 5. Trapezoidal slots 7 are provided on the surfaces of the two connecting plates 6. The two trapezoidal blocks 8 are fixedly connected to the surface of the radiator bellows 4. The two trapezoidal blocks 8 are respectively slidably connected to the inside of the two trapezoidal slots 7.

[0026] The hot air isolation baffle 5 is fixedly installed on the surface of the two trapezoidal blocks 8 by fixing the two connecting plates 6 on the surface of the two trapezoidal blocks 8, and then the hot air isolation baffle 5 is fixedly installed on the surface of the radiator bellows 4, and the hot air isolation baffle 5 is located on the upper side of the cooling fan 15. When the cooling fan 15 inside the radiator bellows 4 rotates, the hot air isolation baffle 5 is added to separate the cold air and the hot air at the cooling air inlet to the greatest extent, thereby reducing the heat of the cooling air and improving the heat dissipation effect.

[0027] A slide groove 9 is provided inside the two connecting plates 6, and a trapezoidal fixed plate 10 is slidably connected inside the slide groove 9. A protrusion 11 is fixedly connected to the bottom of the trapezoidal fixed plate 10, and a spring 12 is fixedly connected to the surface of the trapezoidal fixed plate 10. One end of the spring 12 away from the trapezoidal fixed plate 10 is fixedly connected to the inner wall of the slide groove 9.

One end of the trapezoidal fixed plate 10 away from the spring 12 is slidably clamped inside the fixed card groove 14.

[0028] When installing the hot air isolation baffle 5, the staff first places the two connecting plates 6 on the upper side of the two trapezoidal blocks 8, and then the staff only needs to slide the hot air isolation baffle 5 downward and drive the two connecting plates 6 to slide downward and get stuck on the surfaces of the two trapezoidal blocks 8 through the two trapezoidal slots 7. When the connecting plate 6 slides downward, it drives the trapezoidal fixing plate 10 to slide downward, and makes the inclined surface 13 squeeze the top of the trapezoidal block 8. The trapezoidal fixing plate 10 is squeezed by the top of the trapezoidal block 8 and slides to squeeze the spring 12. When the trapezoidal fixing plate 10 slides to the position of the fixed slot 14, the spring 12 can release the elastic force and push the trapezoidal fixing plate 10 to slide into the inside of the fixed slot 14, so that the hot air isolation baffle 5 can be fixedly installed on the surfaces of the two trapezoidal blocks 8 and the radiator bellows 4.

[0029] When the staff needs to disassemble the hot air isolation baffle 5, the staff only needs to use two fingers to slide the two trapezoidal fixing plates 10 through the two protrusions 11 at the same time to disengage them from the inside of the fixing slot 14, and then directly slide the hot air isolation plate 5 to the upper side to complete the disassembly.

[0030] Working principle: the engine hot air isolation baffle which is easy to disassemble, the hot air isolation baffle 5 is located at the upper side of the cooling fan 15. When the cooling fan 15 inside the radiator bellows 4 rotates, the hot air isolation baffle 5 is added to separate the cold air and the hot air at the cooling air inlet to the greatest extent. The staff only needs to slide the hot air isolation baffle 5 downward and drive the two connecting plates 6 to slide downward and get stuck on the surfaces of the two trapezoidal blocks 8 through the two trapezoidal slots 7. When the connecting plate 6 slides downward, it drives the trapezoidal fixing plate 10 to slide downward, and makes the inclined surface 13 squeeze the top of the trapezoidal block 8. The trapezoidal fixing plate 10 is squeezed by the top of the trapezoidal block 8 and slides to squeeze the spring 12. When the trapezoidal fixing plate 10 slides to the position of the fixed slot 14, the spring 12 can release the elastic force and push the trapezoidal fixing plate 10 to slide into the inside of the fixed slot 14, and the hot air isolation baffle 5 can be fixedly installed on the surfaces of the two trapezoidal blocks 8 and the radiator bellows 4.
