[0026] The connecting mechanism 9 includes a second mounting groove 901, which is symmetrically arranged on the back of the connecting plate 7. A movable plate 906 is slidably connected to the inner side of the second mounting groove 901. A clamping block 905 is fixedly installed on one side of the movable plate 906. The clamping end of the clamping block 905 slides through the groove wall of the second mounting groove 901. The clamping end of the clamping block 905 and the clamping hole 402 are clamped together. A sleeve rod 903 is symmetrically fixedly installed on the side of the movable plate 906 away from the clamping block 905. A sleeve 902 is fixedly installed on the inner side of the second mounting groove 901. One end of the sleeve rod 903 away from the movable plate 906 is slidably connected to the inner side of the sleeve 902. The outer sides of the sleeve rod 903 and the sleeve 902 are sleeved with the same second spring 904. The pushing mechanism 5 and the clamping end of the clamping block 905 are movably connected. When the air curtain machine body 1 is initially installed, First, install and fix the fixing plate 4 on the designated wall, and then insert the air curtain machine body 1 into the connecting groove 401 of the fixing plate 4 through the connecting plate 7. During insertion, the inclined surfaces of the clamping blocks 905 on both sides of the connecting plate 7 are squeezed, so that the movable plate 906 connected to the clamping block 905 slides inside the second installation groove 901. At the same time, the sleeve rod 903 connected to the movable plate 906 slides at the sleeve 902 of the second installation groove 901, and the movable plate 906 compresses the sleeve rod 903 and the second spring 904 outside the sleeve 902. When the connecting plate 7 is inserted into the connecting groove 401, the clamping end of the clamping block 905 corresponds to the position of the clamping hole 402. At this time, the second spring 904 elastically returns to push the clamping block 905 connected to the movable plate 906 to clamp into the clamping hole 402 to fix it, thereby facilitating the rapid installation of the air curtain machine body 1.

[0027] The ejection mechanism 5 includes a first mounting groove 501 and a pressing plate 502. The first mounting groove 501 is opened on one side of the hole 402.

A guide rod 506 is fixedly installed on the inner side of the side groove 505. The movable plate 504 is slidably connected to the outer side of the guide rod 506. A first spring 507 is sleeved on the outer side of the guide rod 506. A ejection block 503 is fixedly installed on the side of the pressing plate 502 facing the hole 402. The ejection block 503 is away from one end of the pressing plate 502. By extending the pressing plate 502 into the inner side of the card hole 402, when disassembling the air curtain machine body 1, it is only necessary to squeeze the pressing plates 502 on both sides of the fixing plate 4, so that the pressing plate 502 slides on the guide rod 506 at the side groove 505 of the first installation groove 501 through the movable plate 504 and compresses the first spring 507. Then, the pressing plate 502 can easily push out the card block 905 at the card hole 402 through the pushing block 503, and finally pull the air curtain machine body 1 out of the connecting groove 401 of the fixing plate 4, thereby realizing the rapid disassembly and maintenance of the air curtain machine body 1 without the aid of any external tools.

[0028] refer to Figure 3 The connecting plate 7 is plugged into the connecting groove 401 on the side away from the air curtain body 1, and the plug-in end of the clamping block 905 is inclined toward the side of the connecting groove 401. The connecting plate 7 and the connecting groove 401 of the fixing plate 4 are plugged in, which makes it convenient to insert the air curtain body 1 into the fixing plate 4 and connect and fix it with the connecting mechanism 9.

[0029] refer to Figure 3 A sliding groove 11 is symmetrically opened on the inner side of the second mounting groove 901, and the end of the connecting plate 7 is slidably connected to the inner side of the sliding groove 11. By sliding the end of the connecting plate 7 on the sliding groove 11 in the second mounting groove 901, the stability of the movement of the connecting plate 7 can be further improved.

[0030] refer to Figure 4 The movable plate 504 is slidably connected to the inner side of the side groove 505. A rod groove 14 is provided on the side of the side groove 505 close to the card hole 402. One end of the guide rod 506 and the first spring 507 are both provided on the inner side of the rod groove 14. By providing the rod groove 14 at the side groove 505, the rod groove 14 facilitates the storage of the first spring 507 sleeved on the guide rod 506 on one side of the pressing plate 502.

[0031] refer to Figure 4 A sliding hole 13 is provided on the inner side of the movable plate 504, and the movable plate 504 is slidably connected to the outer side of the guide rod 506 through the sliding hole 13. The sliding hole 13 on the movable plate 504 can facilitate the sliding of the movable plate 504 on the guide rod 506 at the side groove 505.

[0032] refer to Figure 2 and Figure 4The front of the fixed plate 4 is symmetrically fixed with a matching block 12, and the back of the air curtain machine body 1 is provided with a matching groove 10. The matching block 12 and the matching groove 10 are plug-in connected. The matching block 12 on the fixed plate 4 can be conveniently plugged into the matching groove 10 on the air curtain machine body 1, thereby facilitating the docking operation between the connecting plate 7 on the air curtain machine body 1 and the connecting groove 401 on the fixed plate 4.

[0033] refer to Figure 2 , countersunk holes 8 are symmetrically opened on the inner side of the connecting groove 401, and handles 6 are fixedly installed on the ends of the air curtain machine body 1. The countersunk holes 8 on the inner side of the connecting groove 401 can be used to facilitate the installation of the fixing plate 4 on the wall, and the handle 6 on the air curtain machine body 1 can facilitate the disassembly operation of the air curtain machine body 1.

[0034] Principle and advantages of use: During use, when the air curtain body 1 is installed for the first time, the fixing plate 4 is first fixed on the designated wall, and then the air curtain body 1 is inserted into the connecting groove 401 of the fixing plate 4 through the connecting plate 7. At this time, the installer can use the matching block 12 and the matching groove 10 to align and plug in the outside to make the connecting plate 7 quickly inserted into the connecting groove 401. During insertion, the inclined surfaces of the clamping blocks 905 on both sides of the connecting plate 7 are squeezed, so that the movable plate 906 connected to the clamping block 905 slides inside the second installation groove 901. At the same time, the sleeve rod 903 connected to the movable plate 906 slides at the sleeve 902 of the second installation groove 901, and the movable plate 906 compresses the sleeve rod 903 and the second spring 904 outside the sleeve 902. When the connecting plate 7 is inserted into the connecting groove 401, the clamping end of the clamping block 905 corresponds to the position of the clamping hole 402. At this time, the second spring 904 elastically returns to push the clamping block 905 connected to the movable plate 906 to clamp into the clamping hole 402 to fix it.

[0035] During the later disassembly and maintenance of the air curtain machine body 1, it is only necessary to squeeze the pressing plates 502 on both sides of the fixing plate 4, so that the pressing plates 502 slide on the guide rods 506 at the side grooves 505 of the first installation groove 501 through the movable plate 504 and compress the first spring 507. Then, the pressing plate 502 passes through the pushing block 503, which can easily push out the clamping end of the clamping block 905 at the clamping hole 402. Finally, the handle 6 is engaged to pull the air curtain machine body 1 out of the connecting groove 401 of the fixing plate 4 to remove it, which is simpler and more convenient to use and operate.
