Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, in particular to a ventilation duct which is easy to install. Background Art

[0002] In the construction of ventilation systems, the installation of ventilation ducts is a crucial part. Traditional ventilation duct installation methods usually rely on fixing frames to fix the ducts on the wall or ceiling. However, in actual applications, due to the uneven flatness of the wall, this brings many challenges to the installation of ventilation ducts.

[0003] First, the unevenness of the wall makes it difficult for the ventilation duct to remain horizontal or vertical after installation, resulting in deviations in the butt joints between the ducts. This deviation not only affects the overall aesthetics of the ventilation system, but may also affect the ventilation effect.

[0004] Secondly, due to the deviation of the pipe joint surface, the joint screw holes cannot be aligned, making it impossible to make screw connections. To solve this problem, installers usually need to repeatedly adjust the position of the pipe and use fillers or additional support structures to compensate for the unevenness of the wall. This not only increases the difficulty of installation, but also prolongs the installation time. Utility Model Content

[0009] Preferably, the outer ends of the first connecting plate and the second connecting plate are both arc-shaped, and the arc-shaped outer ends increase their safety and prevent scratches during installation.

[0010] Preferably, a filter is installed on the inner wall of the second ventilation duct body, and the filter can prevent dust, debris, etc. from entering the interior of the ventilation duct, thereby maintaining the cleanliness and ventilation effect of the ventilation system.

[0011] Preferably, both ends of the second ventilation duct body are fixedly mounted with a snap-fit ​​frame, and the outer surface of the snap-fit ​​frame is wrapped with rubber. The design of the snap-fit ​​frame makes it easier to position and fix the ventilation duct during connection, thereby improving installation efficiency. The rubber wrapping increases the tightness and sealing of the connection, reducing the risk of air leakage.

[0012] Preferably, an inspection door is movably installed on the outer surface of the second ventilation duct body, and a handle is fixedly installed on the outer surface of the inspection door.

[0015] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0016] 1. The utility model uses the adjustment plate to cooperate with multiple sets of springs and dampers, so that the ventilation duct can flexibly adapt to the unevenness of the wall or installation surface, without repeatedly adjusting the duct position or using additional support structures. This not only speeds up the installation speed, but also improves the installation accuracy.

[0017] 2. The utility model allows fine adjustment during installation through the design of the slide groove and movable block on the second connecting plate. Even if there is a certain deviation, the alignment of the screw holes can be ensured, so that the installation can be completed smoothly. This feature greatly increases the flexibility and fault tolerance of installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Furthermore, the outer ends of the first connecting plate 8 and the second connecting plate 9 are both arc-shaped, which increases their safety and prevents scratches during installation.

[0028] Furthermore, a filter screen 6 is installed on the inner wall of the second ventilation duct body 2, and the filter screen 6 can prevent dust, debris, etc. from entering the interior of the ventilation duct, thereby maintaining the cleanliness and ventilation effect of the ventilation system.

[0029] Furthermore, both ends of the second ventilation duct body 2 are fixedly mounted with a snap-fit ​​frame 5, and the outer surface of the snap-fit ​​frame 5 is wrapped with rubber. The design of the snap-fit ​​frame 5 makes it easier to position and fix the ventilation duct during connection, thereby improving installation efficiency. The rubber wrapping increases the tightness and sealing of the connection, reducing the risk of air leakage.

[0030] Furthermore, an inspection door 3 is movably installed on the outer surface of the second ventilation duct body 2, and a handle 4 is fixedly installed on the outer surface of the inspection door 3. The arrangement of the inspection door 3 enables it to be conveniently opened and closed when the ventilation duct needs to be inspected or maintained, thereby improving the convenience of maintenance. The handle 4 makes operation easier, and the inspection door can be easily opened without using additional tools.

[0031] Furthermore, the outer surface of the handle 4 is wrapped with rubber. The rubber-wrapped handle 4 not only increases the friction force, making the grip more stable, but also improves the comfort during use and prevents hand injuries.

[0032] Furthermore, the width of the snap-fit ​​frame 5 is smaller than the width of the inner wall of the first ventilation duct body 1, ensuring that the snap-fit ​​frame 5 can be smoothly inserted into the interior of the first ventilation duct body 1 to achieve a tight connection. At the same time, it also avoids the risk of installation difficulties or damage to the duct due to size mismatch during the installation process.

[0033] Working principle: During the installation of the ventilation duct, first, place the first ventilation duct body 1 and the second ventilation duct body 2 in a predetermined position. Due to the unevenness of the wall or the installation surface, there may be a gap or tilt between the duct and the wall. At this time, the multiple groups of springs 711 installed between the adjustment plate 7 and the first ventilation duct body 1 and the second ventilation duct body 2 play an important role. The spring 711 can be extended and retracted according to the actual situation of the wall. Through the cooperation of the adjustment plate 7 and the damper 712, the duct and the wall are well fitted, thereby ensuring the horizontality and verticality of the duct. Next, the first connecting plate 8 of the first ventilation duct body 1 is docked with the second connecting plate 9 of the second ventilation duct body 2. Since the outer surfaces of the first connecting plate 8 and the second connecting plate 9 are provided with multiple groups of screw holes, screw connection can be conveniently performed. At the same time, the design of the slide groove and the movable block 911 on the second connecting plate 9 makes it possible to fine-tune the alignment of the screw holes by sliding the movable block 911 in the slide groove even if there is a certain deviation during the docking process. Once the screw holes are aligned, the first connecting plate 8 and the second connecting plate 9 can be firmly connected together by screws to complete the installation of the ventilation duct. The entire installation process does not require repeated adjustment of the duct position or the use of additional support structures, which greatly improves the installation efficiency and stability. In addition, due to the buffering effect of the spring 711 and the damper 712, the ventilation duct can resist certain external forces and vibrations after installation, thereby ensuring the long-term stable operation of the ventilation system.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
