[0026] Reference Figure 1-4 This utility model provides a central air conditioning structure that is easy to maintain, comprising: an air conditioning housing 1, an installation groove 2 on the lower surface of the air conditioning housing 1, a grille 3 slidably connected to the inner surface of the installation groove 2, a slot 4 on the right surface of the grille 3, a filter 5 slidably connected to the inner surface of the slot 4, a buckle seat 6 fixedly connected to the lower surface of the air conditioning housing 1, an opening groove 16 on the outer surface of the buckle seat 6 to facilitate the installation of the grille 3, and a slot 17 on the inner surface of the opening groove 16.

[0027] The snap-fit ​​assembly 7 includes a fixing box 8, a pressure rod 9, a pressure plate 10, a wedge block 11, a slide rod 12, a spring 13, an L-shaped snap-fit ​​14, and a trapezoidal inclined block 15. The inner surface of the fixing box 8 is slidably connected to the pressure rod 9, the lower end of the pressure rod 9 is fixedly connected to the pressure plate 10, and the upper end of the pressure rod 9 is fixedly connected to the wedge block 11. The slide rod 12 is fixedly connected inside the fixing box 8, the outer surface of the slide rod 12 is provided with a spring 13, and the outer surface of the slide rod 12 is slidably connected to the L-shaped snap-fit ​​14. The outer surface of the L-shaped snap-fit ​​14 is fixedly connected to... There is a trapezoidal inclined block 15, and the inner surface of the slot 17 is adapted to the L-shaped buckle 14 to facilitate the fixing of the grid plate 3. There are two buckle components 7 and they are symmetrically distributed. The lower surface of the grid plate 3 is fixedly connected to the fixing box 8. The outer surface of the wedge block 11 is slidably connected to the trapezoidal inclined block 15, the outer surface of the wedge block 11 is slidably connected to the fixing box 8, the outer surface of the trapezoidal inclined block 15 is slidably connected to the fixing box 8, the outer surface of the L-shaped buckle 14 is slidably connected to the fixing box 8, and both ends of the spring 13 are fixedly connected to the L-shaped buckle 14.

[0028] Working principle: When it is necessary to inspect the internal components of the air conditioner housing 1, simply press the pressure plate 10 on both sides of the latch assembly 7. This drives the pressure rod 9 to slide the wedge block 11 along the inclined surface of the trapezoidal inclined block 15. This causes the corresponding two L-shaped latches 14 to move towards each other along the slide rod 12, compressing the spring 13. This disengages the L-shaped latches 14 from the inside of the latch groove 17, thus releasing the restriction on the mounting groove 2. Then, the grille plate 3 can be directly removed along the mounting groove 2 to expose the internal components of the air conditioner housing 1 for inspection. After the grille plate 3 is removed, it can be directly... Tilt the grille plate 3 to empty the filter 5 inside the slot 4 for cleaning, improving practicality. After the internal components of the air conditioner housing 1 are repaired, simply insert the cleaned filter 5 into the slot 4, then press the pressure plate 10 again and align the L-shaped buckle 14 with the opening slot 16 and snap it in. When the grille plate 3 is fully inserted into the mounting slot 2 and the L-shaped buckle 14 corresponds to the slot 17, release the pressure plate 10. Under the rebound force of the spring 13, the L-shaped buckle 14 will automatically insert into the corresponding slot 17, thus completing the installation of the grille plate 3. It is simple, convenient, and requires no tools, making it highly practical.
