One end of the sliding column 4 is fixedly connected with a limiting column 3 for limiting the sliding column 4, and the sliding column 4 is externally fixedly connected with a tooth 5 for meshing with the gear 9. The top of the base 2 is fixedly connected with a base 2 6, and the base 2 6 is internally rotatably connected with a fixed column 7 for driving the extrusion strip 12 to rotate. The fixed column 7 is provided with a special-shaped groove 8 for sliding the fixing bolt 10. The bottom of the fixed column 7 is fixedly connected with a gear 9 for driving the gear 9 to rotate and move up and down. The internal rotation of the base 2 is connected to the outside of the gear 9. The outside of the gear 9 meshes and intersects with the outside of the teeth 5. The top of the fixed column 7 is fixedly connected with an extrusion strip 12 for extruding and clamping the fixed plate 21. The outside of the outer shell 1 is fixedly connected with two fixed plates 21 for being clamped and fixed to connect the outer shell 1. The top of the fixed plate 21 is fixedly connected to the bottom of the extrusion strip 12 and is fixed. The inside of the base 2 6 is fixedly connected with a fixing bolt 10. A notch 11 is provided inside the base 2 6 for the sliding of the gear 9. The outside of the outer shell 1 is fixedly connected with a buffer assembly.

[0025] like Figure 3 , Figure 4As shown: the buffer assembly includes a plurality of square plates 13, and a movable plate 14 is fixedly connected to the bottom of the plurality of square plates 13 in the same row for moving left and right to relieve vibration. The bottom of the movable plate 14 is fixedly connected to a chassis 17 for sliding of a movable column 18. The outside of the chassis 17 is fixedly connected to a lubricating coating 24 for facilitating the sliding of the movable column 18 on the chassis 17. The lubricating coating 24 is made of a polymer film. The bottom of the chassis 17 is fixedly connected to the movable column 18. A plurality of holes 15 are provided inside the movable plate 14 for placing springs 16. The bottom of the plurality of square plates 13 in the same row is fixedly connected to a plurality of springs 16 for reducing the shaking of the movable plate 14.

The inside of the housing 1 is fixedly connected to two pipes 22, and the inside of the housing 1 is connected to two rubber rings 23 to enhance the sealing of the housing 1.

[0026] Compared with some devices in the prior art, the above content solves the problem that some automobile heating devices are time-consuming and laborious to install and disassemble and generate loud noise during operation.

[0027] Working principle: First, align and splice the two shells 1 along the rubber ring 23, and at the same time, the fixing plates 21 are in contact, and the limiting column 3 is held and pushed forward inside the base 1 2, so that the sliding column 4 and the teeth 5 are also driven forward, and the teeth 5 are engaged with the special-shaped groove 8 to make the gear 9 rotate and move upward in the notch 11, so that the extrusion bar 12 is driven to rotate to squeeze and clamp the two fixing plates 21. When a certain height is reached, the fixing bolt 10 inside the base 2 6 limits the fixing column 7 in the special-shaped groove 8. When disassembling, you only need to hold the limiting bolt 10 to limit the fixing column 7 in the special-shaped groove 8. The positioning column 3 moves it outward, and the fixing plate 19 is fixed to the outer shell 1 and the interior of the vehicle body with bolts 20 and nuts 25 respectively. When the air conditioning and heating device is running, the warm air is transmitted through the pipe 22, and the device produces slight vibrations, causing the movable plate 14 to shake left and right. The internal movable column 18 slides inside the chassis 17 through the lubricating coating 24, thereby reducing the shaking of the movable plate 14. At the same time, the two ends of the spring 16 are fixed to the square plate 13 and also move with the movable plate 14 inside the hole 15, so that the noise generated when the air conditioning and heating device is running is reduced.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
