[0006] Preferably, the second insert plate is inserted inside the first limiting plate, and the first insert plate is located between the second positioning plate and the inner side of the exhaust fan housing.
[0007] Preferably, the aforementioned limiting component includes a limiting seat and two third inserts, with the two third inserts disposed on both sides of the limiting seat. One side of the limiting seat abuts against the outer side of the enclosure body and is provided with a second limiting plate.
[0008] Preferably, the exhaust fan housing is provided with a third limiting plate on each of the two adjacent inner sides, and the two third insert plates are respectively inserted into the interior of the third limiting plate.
[0009] Preferably, the top of the limiting seat is provided with a wiring hole, and the upper parts of both sides of the limiting seat are provided with limiting grooves.
[0010] Preferably, the exhaust fan housing is provided with limit brackets on both adjacent inner sides, and a limit protrusion is provided on one side of the limit bracket.
[0011] Preferably, the aforementioned limiting protrusion matches the limiting groove, and the limiting protrusion is engaged inside the limiting groove.
[0012] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:
[0013] 1. This utility model completes the assembly of the enclosure body by inserting the first and second insert plates at both ends of the enclosure body into the space between the second positioning plate and the inner side of the exhaust fan housing and the space between the inner side of the first limiting plate and the first positioning plate, respectively. Then, the enclosure body can be fixed by a fan mounting bracket and a limiting seat. The enclosure body can be installed without welding, which improves the assembly efficiency of the enclosure body.

[0025] Example
[0026] Please see Figure 1-6 This utility model provides a technical solution: an exhaust fan enclosure fixing structure, including an exhaust fan housing 1, an enclosure body 2 installed inside the exhaust fan housing 1, an integrally bent support plate 3 at the bottom of the enclosure body 2, an integrally bent first insert plate 4 and a second insert plate 5 at both ends of the enclosure body 2, and a plurality of fan mounting supports 6 on the exhaust fan housing 1. By folding three fan mounting supports 6, one of the fan mounting supports 6 abuts against the top side of the enclosure body 2, which can limit the enclosure body 2.
[0027] One of the fan mounting brackets 6 abuts against the upper side of the enclosure body 2. One side of the exhaust fan housing 1 is respectively provided with an integrally bent first positioning plate 8 and a second positioning plate 9. One side of the first positioning plate 8 is provided with an integrally bent first limiting plate 7. The second insert plate 5 is inserted into the inside of the first limiting plate 7. The first insert plate 4 is located between the second positioning plate 9 and the inner side of the exhaust fan housing 1. By inserting the first insert plate 4 and the second insert plate 5 at both ends of the enclosure body 2 into the space between the second positioning plate 9 and the inner side of the exhaust fan housing 1 and between the inner side of the first limiting plate 7 and the first positioning plate 8, and then the support plate 3 at the bottom of the enclosure body 2 abuts against the bottom of the exhaust fan housing 1, the assembly of the enclosure body 2 can be completed. Limiting components are provided on the outer side of the enclosure body 2 and the inner side of the exhaust fan housing 1.
[0028] To fix and limit the enclosure body 2, the limiting assembly includes a limiting seat 10 and two third insert plates 11. The two third insert plates 11 are disposed on both sides of the limiting seat 10. One side of the limiting seat 10 abuts against the outer side of the enclosure body 2 and is provided with a second limiting plate 13. The two adjacent inner sides of the exhaust fan housing 1 are provided with third limiting plates 14. The two third insert plates 11 are respectively inserted into the interior of the third limiting plates 14. The limiting seat 10 is inserted to the outer side of the exhaust fan housing 1 and the enclosure body 2, so that the third insert plates 11 at both ends of the limiting seat 10 are respectively inserted into the inner side of the third limiting plates 14. When the bottom of the limiting seat 10 abuts against the inner bottom of the exhaust fan housing 1, the second limiting plate 13 is engaged with the enclosure body 2, thereby fixing the enclosure body 2 a second time, improving the stability of the enclosure body 2 installation, and completing the installation of the enclosure body 2 without welding, improving the assembly efficiency of the enclosure body 2 and reducing the assembly cost of the enclosure body 2.
[0029] To improve the reliability of fixing the enclosure body 2, the top of the limiting seat 10 is provided with a wiring hole 12, and the upper parts of both sides of the limiting seat 10 are provided with limiting grooves 15. The two adjacent inner sides of the exhaust fan housing 1 are provided with limiting brackets 16, and one side of the limiting bracket 16 is provided with a limiting protrusion 17. The limiting protrusion 17 matches the limiting groove 15 and is engaged inside the limiting groove 15. During the downward movement of the limiting seat 10, the ends of the two third inserts 11 abut against the outer side of the limiting bracket 16, thereby pushing the limiting bracket 16 to undergo elastic deformation. When the limiting seat 10 does not move, the limiting protrusion 17 moves to the outer side of the limiting groove 15. The limiting bracket 16 resets and causes the limiting protrusion 17 to abut against the inside of the limiting groove 15, thus fixing the position of the limiting seat 10.
[0030] The working principle or structural principle is as follows: When assembling the enclosure body 2, the first insert plate 4 and the second insert plate 5 at both ends of the enclosure body 2 are inserted between the second positioning plate 9 and the inner side of the exhaust fan housing 1, and between the inner side of the first limiting plate 7 and the first positioning plate 8, respectively. Then, the support plate 3 at the bottom of the enclosure body 2 abuts against the bottom of the exhaust fan housing 1, thus completing the assembly of the enclosure body 2. Furthermore, by folding down the three fan mounting supports 6, with one of the fan mounting supports 6 abutting against the top side of the enclosure body 2, the enclosure body can be further assembled. 2. Limit the position, and then insert the limiting seat 10 to the outside of the exhaust fan housing 1 and the enclosure body 2, so that the third insert plates 11 at both ends of the limiting seat 10 are inserted into the inside of the third limiting plate 14 respectively. When the bottom of the limiting seat 10 abuts against the bottom of the inner side of the exhaust fan housing 1, the second limiting plate 13 is engaged with the enclosure body 2, thereby fixing the enclosure body 2 a second time, improving the stability of the enclosure body 2 installation, and the enclosure body 2 can be installed without welding, thus improving the assembly efficiency of the enclosure body 2.
[0031] During the downward movement of the limiting seat 10, the ends of the two third insert plates 11 abut against the outer side of the limiting frame 16, thereby pushing the limiting frame 16 to undergo elastic deformation. When the limiting seat 10 does not move, the limiting protrusion 17 moves to the outer side of the limiting groove 15. The limiting frame 16 resets and causes the limiting protrusion 17 to abut against the inside of the limiting groove 15, thus fixing the position of the limiting seat 10 and improving the reliability of fixing the enclosure body 2. After the enclosure body 2 and the limiting seat 10 are installed, the fan can be installed on the fan mounting bracket 6 with screws.
