DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a technical solution:

[0026] See also Figures 1 to 3A chassis mechanism for a duct machine comprises a duct machine body 1, a ventilation duct 2 is passed through the front end of the duct machine body 1, telescopic rods 3 are fixed to the four corners of the bottom end of the duct machine body 1, a chassis 4 is connected below the telescopic rods 3, and an adjustment mechanism 5 for adjusting the position of the chassis 4 is arranged between the chassis 4 and the duct machine body 1; protective mechanisms 8 for protecting the duct machine body 1 are arranged on both sides of the adjustment mechanism 5; the adjustment mechanism 5 comprises a fixing sleeve 501, four fixing sleeves 501 are fixed on the top of the chassis 4, a rotating rod 502 is passed through the inside of the fixing sleeve 501, and the rotating rod 502 penetrates into the fixing sleeve 5 A support shaft 503 is passed through the inner wall of one end of 01, and a damping spring 504 is embedded in one end of the rotating rod 502 passing through the fixed sleeve 501. The end of the damping spring 504 away from the rotating rod 502 is connected to a connecting head 505, and the outer wall of the connecting head 505 is rotatably connected to a roller 506. The rotating rod 502 forms a rotating structure with the fixed sleeve 501 through the support shaft 503. The structure of the fixed sleeve 501 is a U-shaped structure. The connecting head 505 forms an elastic structure with the rotating rod 502 through the damping spring 504, and the connecting head 505 forms a sliding structure with the duct machine body 1 through the roller 506.

[0027] By adopting the above technical scheme, the air duct machine body 1 is fixed to the top of the building by the hanging rod, and the telescopic rod 3 makes it easy for the chassis 4 to slide and adjust the position between the air duct machine body 1, so that it contacts the ceiling keel. The rotating rod 502 is turned to rotate through the support shaft 503, and rotates inside the fixing sleeve 501 to maintain a vertical state with the chassis 4. During the rotation, the damping spring 504 elastically pushes the connecting head 505 to allow the roller 506 to slide against the bottom end of the air duct machine body 1 and penetrate into the reserved reserved hole for limiting. The elastic push of the damping spring 504 makes it easy to adjust according to the position of the ceiling keel, so that the chassis 4 can always contact the ceiling keel, and after being fixed by bolts, it has a certain supporting force. The damping spring 504 has a certain shock-absorbing effect when it is hit or vibrated, and the ventilation duct 2 and the outer wall of the ceiling are flush to achieve an aesthetic effect.

[0028] Specifically, Figure 1 , Figure 2 and Figure 4As shown, a placement groove 6 is provided on one side of the fixing sleeve 501 at the top of the chassis 4, and a telescopic plate 7 is fixed on the other side of the fixing sleeve 501 at the top of the chassis 4. The protective mechanism 8 includes an extension rod 801, and the extension rod 801 is fixed to the two ends of the support shaft 503 passing through the fixing sleeve 501, and a limiting rod 802 is fixed to the end of the extension rod 801 away from the support shaft 503. The protective mechanism 8 also includes a limiting groove 803, and the limiting groove 803 is provided on the inner wall of the limiting rod 802. A protective side plate 804 is penetrated into the limiting groove 803, and an anti-collision pad 805 is fixed to the protective side plate 804 facing the outer wall of the duct machine body 1. The protective side plate 804 forms a sliding structure with the limiting groove 803 and the limiting rod 802, and the protective side plate 804 is bonded and connected to the anti-collision pad 805.

[0029] By adopting the above technical scheme, the return air duct of the duct machine body 1 is conveniently placed and limited by the placement groove 6, and a wind circulation is formed with the ventilation duct 2 to keep the duct machine body 1 working. When the rotating rod 502 rotates, the extension rod 801 is driven by the support shaft 503 to rotate the limiting rod 802. Therefore, the rotating rod 502 can be adjusted and rotated by manually rotating the limiting rod 802. When the limiting rod 802 is rotated to a vertical state with the chassis 4, it slides into the protective side plate 804 through the limiting groove 803, so as to protect both sides of the outer wall of the duct machine body 1. At the same time, the two ends of the anti-collision pad 805 bonded to the protective side plate 804 abut against one side of the two limiting rods 802 to prevent the limiting rod 802 from sliding by itself, thereby improving the stability of the rotating rod 502 and the limiting rod 802. At the same time, the anti-collision pad 805 prevents the protective side plate 804 from colliding with the duct machine body 1 and causing damage.

[0030] Working principle: After the air duct machine body 1 is fixed by the hanging rod, the limit rod 802 is moved, thereby driving the extension rod 801 to make the support shaft 503, driving the rotating rod 502 to rotate in the fixing sleeve 501, and the damping spring 504 elastically pushes the connecting head 505 to slide through the roller 506 at the bottom end of the air duct machine body 1 and penetrate into the reserved hole for limiting, so that the distance between the chassis 4 and the air duct machine body 1 can be adjusted, so that the chassis 4 can fit the ceiling keel, and is fixed by bolts, and cooperates The telescopic rod 3 and the telescopic plate 7 prevent the air duct machine body 1 and the chassis 4 from being separated. The placement groove 6 facilitates the placement of the return air duct and forms a circulation with the ventilation duct 2. When the extension rod 801 rotates and is perpendicular to the chassis 4, it slides into the protective side plate 804 through the limit groove 803 to protect the side of the air duct machine body 1. The anti-collision pad 805 prevents excessive collision during collision. The anti-collision pad 805 is in contact between the two limit rods 802 to prevent the limit rods 802 from rotating or loosening.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
