[0026] Please refer to Figure 1-2 , a universal fixing device for range hood hanging pieces applicable to different positions, including an adjustment box 3. The upper part of the adjustment box 3 is fixedly installed on the overhead wall panel A through a back fixing piece 1 and a fixing bolt 2. The adjustment box 3 is an open structure, and the open side is closely attached to the overhead wall panel A. A connecting piece 304 is provided inside the box body. The upper end of the connecting piece 304 is connected to the upper inner side of the box body through a connecting piece spring 303, and a hanger fixing piece 4 is fixedly installed at the lower end. A fixing piece 302 is inserted on the inner side wall of the box body. The lower end of the fixing piece 302 is connected to the inner bottom of the box body through a fixing piece spring 301. The fixing piece 302 and the connecting piece 304 are snap-connected, and a fixing button 5 is inserted at the lower part outside the adjustment box 3.

[0027] The fixing member 302 has a trapezoidal structure, and a plug-in block is provided at the lower part. The two sides of the connecting member 304 are provided with locking teeth, and the locking teeth are engaged with the top angles of the corresponding trapezoidal structures on the two sides of the fixing member 302. The middle part of the fixing knob 5 is cylindrical, and the two sides are respectively a rectangular section and a cylindrical section.

[0028] A plug-in hole and a fixing knob mounting hole 306 are formed in the side wall of the adjusting box 3. The plug-in hole is matched with the plug-in block at the lower part of the fixing member 302. The fixing knob mounting hole 306 has a lock-shaped structure, with a circular hole at the upper part and a rectangular hole at the lower part. The diameter of the cylindrical part in the middle of the fixing knob 5 is smaller than the width of the rectangular hole at the lower part of the fixing knob mounting hole 306. The hanging piece fixing member 4 has an L-shaped structure. The cylindrical section on the fixing knob 5 is placed on the horizontal section of the hanging piece fixing member 4, and the fixing member spring 301 is located outside the hanging piece fixing member 4.

[0029] The back fixing member 1 is placed inside the overhead wall panel A. The upper part of the adjusting box 3 is provided with a mounting plate 305 that cooperates with the back fixing member 1, and a mounting through hole for the fixing bolt 2 is formed in the mounting plate 305.

[0030] An installation method for a universal fixing device for a smoke exhaust fan hanging piece applicable to different positions includes the following steps:

[0031] Step 1: Before installation, prefabricate installation holes in the overhead wall panel A.

[0032] Step 2: Place the open end of the box body of the adjusting box 3 closely against the overhead wall panel A, and fix the mounting plate 305 on the upper part of the adjusting box 3 to the overhead wall panel A through the back fixing member 1 and the fixing bolt 2.

[0033] Step 3: After determining the position of the installation point on the back of the smoke exhaust fan B, connect the rectangular section of the fixing knob 5 to the installation hole on the back of the smoke exhaust fan B. The cylindrical section is inserted into the interior of the adjusting box 3 along the circular hole at the upper part of the fixing knob mounting hole 306, and slides down along the rectangular hole at the lower part of the fixing knob mounting hole 306 to the installation point position. At the same time, pull out the fixing member 302 outward, so that the locking teeth on the connecting member 304 are separated from the corresponding mating top angles on the fixing member 302. During the sliding-down process, the inner cylindrical section of the fixing knob 5 contacts the horizontal section of the L-shaped hanging piece fixing member 4 to form a support.

[0034] Step 4: After the installation position of the smoke exhaust fan B is adjusted, loosen the connecting member 304, so that the locking teeth on the connecting member 304 are engaged with the corresponding mating top angles on the fixing member 302, and the smoke exhaust fan B can be fixed.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
