Example 1

Referring to fig. 1 to 4, a range hood comprises a housing 1 and a panel bracket 2 arranged at the front side of the housing 1, wherein an air inlet 21 is formed in the panel bracket 2, a fan (not shown) can be arranged in the housing 1, and the panel bracket 2 is usually a sheet metal part.

The panel bracket 2 is provided in front with a smoke baffle 3 which can turn over to open and close the air inlet 21, and in this embodiment, the smoke baffle 3 is of a single stage, i.e., the smoke baffle 3 covers the front side portion of the entire housing 1 (panel bracket 2). Alternatively, a glass panel may be provided on the front side of the panel bracket 2, the smoke barrier 3 may be provided under the glass panel, or the smoke barrier 3 may be located between two glass panels. A decorative shaft 4 is provided on the panel bracket 2 at a position on top of the smoke baffle 3 to avoid exposure of a gap between the smoke baffle 3 and the panel bracket 2 (housing 1).

The panel bracket 2 and the decoration shaft 4 are connected through the connecting component 5, and the panel bracket 2, the decoration shaft 4 and the connecting component 5 form a decoration shaft installation structure. Referring to fig. 4 to 8, the panel bracket 2 has a first mounting hole 22 formed at the top thereof, and in this embodiment, the first mounting hole 22 is square, and may have at least two mounting holes arranged at intervals in the left-right direction. The second mounting holes 41 are formed in corresponding positions on the decoration shaft 4, and the second mounting holes 41 can be circular.

The connecting assembly 5 comprises a connecting piece 51 and a screw 52, wherein the connecting piece 51 can be made of stainless steel, cold-rolled plates or other materials, and has certain elasticity. The connector 51 includes a main body 511 and a bending portion 512 formed at one end of the main body 511, the bending portion 512 having an arched shape with respect to the main body 511, as shown in the present embodiment, the bending portion 512 having an S-shape for pressing the panel bracket 2. The main body 511 is provided with a through hole 513 through which the screw 52 passes. The other end of the main body 511 opposite to the bent portion 512 is formed with a flange 514. The direction in which the bent portion 512 arches is opposite to the direction in which the flange 514 is folded. The decorative shaft 4 is further provided with a limiting hole 42 at a position adjacent to the second mounting hole 41 for matching with the flanging 514.

When in installation, firstly, the screw 52 passes through the connecting piece 51 to fix the connecting piece with the decoration shaft 4; the connecting member 51 is then passed through the first mounting hole 22 in the panel bracket 2, and then the connecting member 51 is moved along the length direction of the connecting member 51 (the direction in which the bent portion 512 and the flange 514 are connected) so that the bent portion 512 is moved to a position where the panel bracket 2 is located at the periphery of the first mounting hole 22, thereby being able to abut against the side of the panel bracket 2 away from the decorative shaft 4. Because the connecting piece 51 is elastic, the influence of the powder layer material thickness of the panel bracket 2 is small, the design and the installation are convenient and quick, and the reject ratio of the installation of the decoration shaft can be effectively reduced.

Example two

Referring to fig. 9 to 11 and 14, in the present embodiment, the difference from the first embodiment is that the connector 51 is in the form of a turnbuckle, and is made of a material such as nylon, and has a certain elasticity. The connecting piece 51 comprises a fastener body 515, the lower end (the joint with the panel bracket 2) is large, the upper end (the joint with the decoration shaft 4) is small, and a counter bore 516 is arranged in the middle and is matched with the screw 52 for installation. And the lower end portion is unequal in length and width and is not circular. In this embodiment, the fastener body 515 is generally shoe-shaped. The first mounting holes 22 on the panel bracket 2 have a diamond shape.

The fastener body 515 is transversely parallel to the length direction of the decoration shaft 4, when the decoration shaft is installed, after the fastener body 515 is out of the first installation hole 22 of the panel bracket 2, the fastener body 515 is rotated by a certain angle, such as 90 degrees, as shown in fig. 12-14, and the fastener body 515 is clamped with the wall surface of the first installation hole 22.

Because of the characteristics of the diamond-shaped holes, the length of the long diagonal line is larger than that of the short diagonal line, and the length of the short diagonal line is larger than the distance between the two parallel sides, the connecting piece 51 is in a self-locking state after being installed, and if no external force is interfered, the connecting component 5 cannot fall off.
