[0035] This embodiment discloses an installation structure and a range hood including the installation structure, as Figures 1 to 10 shown. The range hood further includes a smoke collecting cavity 7, a connecting pipe 8 and a chassis 9. The installation structure includes a first connecting member 1, a second connecting member 2, a rotating buckle 3, an installation shaft 4 and a push rod 5. The second connecting member 2 is detachably connected to the first connecting member 1. One of the first connecting member 1 and the second connecting member 2 is disposed on the smoke collecting cavity 7, and the other of the first connecting member 1 and the second connecting member 2 is disposed on the connecting pipe 8; and / or, one of the first connecting member 1 and the second connecting member 2 is disposed on the connecting pipe 8, and the other of the first connecting member 1 and the second connecting member 2 is disposed on the chassis 9.

[0036] That is, at least one end of the connecting pipe 8 is provided with an installation structure. Through relevant structures such as the rotating buckle 3 of the installation structure, the quick connection between the smoke collecting cavity 7 and the connecting pipe 8, and between the connecting pipe 8 and the chassis 9 can be realized. Only by aligning one component with another component and then pushing it in the direction of the other component can the connection be completed. The disassembly and assembly efficiency is high, solving the problem that the installation between the components of the existing split range hood is inconvenient; there is no need to reserve space for connectors such as screws, the application range is wider, and the use experience is good.

[0037] Specifically, a fixed buckle 21 is provided on one of the first connecting member 1 and the second connecting member 2, and the rotating buckle 3 is movably connected to the other of the first connecting member 1 and the second connecting member 2. The rotating buckle 3 can be engaged with and separated from the fixed buckle 21 to connect the first connecting member 1 and the second connecting member 2 together and divide them into two independent individuals.

[0038] The mounting shaft 4 can be provided on the other one of both the first connecting member 1 and the second connecting member 2, or can be provided on the rotary buckle 3, as long as it allows the rotary buckle 3 to rotate around the axis of the mounting shaft 4. The push rod 5 can be used to drive the rotary buckle 3 to rotate around the axis of the mounting shaft 4 to release the engagement with the fixed buckle 21, making disassembly and assembly more convenient.

[0039] The specific shape of the rotary buckle 3 is not limited, as long as it can be engaged with and separated from the fixed buckle 21. In this embodiment, as Figures 2 to 4 shown, the rotary buckle 3 includes a hook 31 and a connecting rod section 32. The driving shaft 6 is provided on one of the push rod 5 and the connecting rod section 32, and a driving shaft mounting hole 51 is provided on the other one of the push rod 5 and the connecting rod section 32. The end of the driving shaft 6 is inserted into the driving shaft mounting hole 51. When the push rod 5 moves, the driving shaft 6 can move synchronously with the push rod 5, and the rotary buckle 3 can rotate around the axis of the driving shaft 6. At this time, the rotary buckle 3 also rotates around the axis of the mounting shaft 4, so as to realize that the push rod 5 drives the rotary buckle 3 to be engaged with and separated from the fixed buckle 21.

[0040] In order to improve the connection stability, the mounting structure includes at least two groups of rotary buckles 3, and correspondingly at least two driving shafts 6 and at least two driving shaft mounting holes 51 are provided. All the driving shaft mounting holes 51 are evenly spaced, and the force on the push rod 5 is more balanced. All the rotary buckles 3 can rotate synchronously, making disassembly more convenient.

[0041] On the basis of the above structure, the hook 31 includes a hook inclined surface 311 and a hook engaging surface 312. As Figure 7 shown, the fixed buckle 21 is provided with a buckle inclined surface 211 and a buckle engaging surface 212. Among them, the buckle inclined surface 211 cooperates with the hook inclined surface 311, and the hook inclined surface 311 can slide along the buckle inclined surface 211 to make the hook 31 swing; the buckle engaging surface 212 cooperates with the hook engaging surface 312 to prevent the hook 31 and the fixed buckle 21 from being separated.

[0042] In order to make the push rod 5 drive the rotary buckle 3 to rotate around the axis of the mounting shaft 4 more labor - saving, the mounting shaft 4 is arranged between the hook 31 and the connecting rod section 32. That is, the hook 31 and the connecting rod section 32 are connected, the mounting shaft 4 is located at the connection of the hook 31 and the connecting rod section 32, and the driving shaft 6 is located at the free end of the connecting rod section 32. The push rod 5 is connected to the rotary buckle 3 through the driving shaft 6. The distance between the connection point of the push rod 5 and the rotary buckle 3 and the mounting shaft 4 is basically equal to the length of the connecting rod section 32. The push rod 5 can make the rotary buckle 3 rotate a large angle by translating a small distance, and the response speed is faster.

[0043] On the basis of the above structure, as Figure 3 and Figure 4As shown in the figure, the push rod 5 includes a rod body 52, an extension section 53 and a handle 54. There is an included angle between the extending direction of the extension section 53 and that of the rod body 52. Specifically, the extension section 53 forms a right angle with the rod body 52 and is respectively attached to two adjacent side wall surfaces of the first connecting member 1 (or the second connecting member 2), which not only provides a large enough installation base for the handle 54 but also makes full use of the space around the first connecting member 1 and the second connecting member 2, making the overall structure more compact. The handle 54 is installed on the extension section 53, and the handle 54 and the rod body 52 are respectively connected to opposite sides of the extension section 53. The push rod 5 can be translated by pulling the handle 54.

[0044] The drive shaft mounting hole 51 is provided on the rod body 52. In order to keep the overall strength of the rod body 52 as much as possible without affecting the rotation of the rotary buckle 3, an avoidance groove 55 is provided on the push rod, and the drive shaft mounting hole 51 is located in the avoidance groove 55. After the end of the connecting rod section 32 is connected to the drive shaft mounting hole 51 through the drive shaft 6, the avoidance groove 55 leaves a rotation space for the rotary buckle 3 to prevent the rotary buckle 3 from being unable to rotate.

[0045] The specific way to realize the reset of the rotary buckle 3 is not limited. In this embodiment, the installation structure further includes a torsion spring (not shown), and the elastic force of the torsion spring is used to drive the rotary buckle 3 to reset. Specifically, a connecting member torsion spring installation groove 11 is provided on the other one of the first connecting member 1 and the second connecting member 2, and a buckle torsion spring installation groove 33 is provided on the rotary buckle 3. One end of the torsion spring is located in the connecting member torsion spring installation groove 11 and the other end is located in the buckle torsion spring installation groove 33, and the installation shaft 4 is passed through the torsion spring. When the rotary buckle 3 is separated from the fixed buckle 21 under the action of the push rod 5, the torsion spring is compressed and stores elastic force; when the pulling force applied to the push rod 5 disappears or is less than the elastic force of the torsion spring, the torsion spring releases the elastic force to make the rotary buckle 3 rotate in the reverse direction, realizing the reset of the rotary buckle 3.

[0046] To ensure that the push rod 5 can only move horizontally and will not move up and down, as Figure 5 shown, a limiting convex rib 12 is provided on the other one of the first connecting member 1 and the second connecting member 2, and a limiting groove 13 is formed between the other one of the first connecting member 1 and the second connecting member 2 and the limiting convex rib 12. The push rod 5 is located in the limiting groove 13. The limiting convex rib 12 can not only support the push rod 5 but also guide it, making the push rod 5 can only be translated.

[0047] The distance between the drive shaft 6 and the installation shaft 4 is basically equal to the length of the connecting rod section 32, that is, the distance between the drive shaft 6 and the installation shaft 4 remains unchanged. When the rotary buckle 3 rotates, the drive shaft 6 will move up and down within a certain range. To avoid the movement of the push rod 5 being jammed, as Figure 7 shown, the width L of the limiting groove 13 is greater than the width H of the push rod 5, and the limiting groove 13 leaves a space for the push rod 5 to float up and down.

[0048] To avoid affecting the normal use of the range hood, both the first connecting piece 1 and the second connecting piece 2 are hollow cylindrical structures inside, and the oil fume airflow can pass through the middle cavity. In one structure, a plurality of rotary buckles 3 are arranged in a circle around the first connecting piece 1 or the second connecting piece 2, making disassembly and assembly more convenient. In another structure, as Figure 5 shown, the cross-section of the first connecting piece 1 and the second connecting piece 2 perpendicular to their own extension directions is rectangular, and the fixed buckle 21 and the rotary buckle 3 are located on one side of the rectangle. Specifically, the fixed buckle 21 and the rotary buckle 3 are on the side close to the wall, and the other sides are connected by connecting pieces such as screws, and the connection structure is more stable and the cost is low.

[0049] Figures 6 to 10 Shown is the installation process of the first connecting piece 1 and the second connecting piece 2. Specifically, Figure 6 and Figure 7 shown are the first connecting piece 1 and the second connecting piece 2 being aligned and ready to start installation. The hook inclined surface 311 abuts against the buckle inclined surface 211. As the first connecting piece 1 gradually approaches the second connecting piece 2, the buckle inclined surface 211 exerts a force F on the hook inclined surface 311, and the rotary buckle 3 starts to rotate around the axis of the installation shaft 4.

[0050] Figure 8 Shown is the hook inclined surface 311 sliding down to the bottom end of the buckle inclined surface 211, and the rotary buckle 3 is about to be separated from the fixed buckle 21. Figure 9 Shown is the hook inclined surface 311 completely disengaging from the buckle inclined surface 211. Under the action of the torsion spring, the rotary buckle 3 starts to reset. Figure 10 Shown is the rotary buckle 3 reset, and the hook engaging surface 312 abuts against the buckle engaging surface 212 from below, realizing the snap connection between the rotary buckle 3 and the fixed buckle 21, and making the first connecting piece 1 and the second connecting piece 2 form an integral structure.

[0051] During disassembly, move the push rod 5 to rotate the rotary buckle 3 until the hook engaging surface 312 is completely disengaged from the buckle engaging surface 212, and then the first connecting piece 1 and the second connecting piece 2 can be separated.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention.
