Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fans, in particular to a panel bracket mesh cover component of an axial flow fan. Background Art

[0002] Axial flow fans, with their wide range of uses, direct airflow in the same direction as the fan's axis. Examples include electric fans and air conditioner outdoor fans. They're called "axial flow" because the air flows parallel to the fan's axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure. Axial flow fans are fixed in position and move air. They primarily consist of a fan impeller and a casing. While simple in structure, they require very high performance.

[0003] Protective mesh covers are installed at both ends of the fan casing to isolate and protect the impeller. After long-term use, dust will accumulate on the surface of the protective mesh covers, and the surface of the protective mesh covers needs to be cleaned in time. However, the existing counter-rotating axial flow fans require multiple bolts to be tightened separately during use to remove the mesh covers. In the process of disassembling and installing the protective mesh covers, many bolts need to be turned repeatedly, resulting in low cleaning efficiency. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See Figure 1-5 , an axial flow fan panel bracket mesh assembly, including a main body assembly 1; the main body assembly 1 includes a shell 11, an organic leaf body 12 is arranged on the inner side of the shell 11; a mesh cover 13 is arranged at one end of the shell 11; a disassembly assembly 2 is provided on the shell 11, and the disassembly assembly 2 includes: a mounting plate 21, fixedly connected to the outer wall of the shell 11; a gear ring 22, rotatably connected to the outer wall of the mounting plate 21; a gear 23, rotatably connected to the outer wall of the mounting plate 21, and a plurality of gears are evenly arranged; a bolt 24 passes through the gear 23 and is engaged with the gear The wheel 23 is slidably connected; the limiting groove 25 is opened on the outer wall of the bolt 24; the clamping mechanism 26 is arranged on the mounting plate 21; the limiting block 27 is fixedly connected to the inner side of the gear 23, and the limiting block 27 is slidably connected to the inside of the limiting groove 25; the clamping mechanism 26 includes: a pressing plate 261, which is arranged on the mounting plate 21; a spring 262, which is arranged on the mounting plate 21, and is provided in plurality, and both ends of each spring 262 are respectively fixedly connected to the outer wall of the pressing plate 261 and the outer wall of the mounting plate 21.

[0029] When ready for use, the housing 11 is placed in the designated position, and the air outlet function is realized through the blade body 12. When the mesh cover 13 needs to be cleaned, the operator manually rotates the gear ring 22 on the mounting plate 21. The rotation of the gear ring 22 drives multiple gears 23 to rotate at the same time. The gear 23 rotates through the limit block 27 and slides in the limit groove 25, thereby driving the bolt 24 to rotate, so that the multiple bolts 24 rotate at the same time, thereby driving the bolt 24 to rotate out of the mesh cover 13, thereby disassembling the mesh cover 13. When the cleaning is completed, the operator puts the mesh cover 13 back to its original position and then rotates the gear ring in the opposite direction. 22 drives multiple bolts 24 to rotate simultaneously, and squeezes the bolts 24 through the clamping mechanism 26, and the auxiliary bolts 24 enter the interior of the mesh cover 13 for spiral fixation, so that the operator does not need to twist the multiple bolts 24 separately for disassembly or fixation, thereby improving the operator's work efficiency; when the operator rotates the ring gear 22 to drive the multiple bolts 24 to rotate simultaneously, the spring 1 262 always tightens the pressure plate 261, so that the pressure plate 261 squeezes the multiple bolts 24 at the same time, and the compression of the bolts 24 by the pressure plate 261 assists the bolts 24 to enter the mesh cover 13 for fixation, thereby improving the stability of the device.

[0030] Example 2

[0031] See Figure 1-5 , based on the first embodiment, an auxiliary fixing function is added;

[0032] An auxiliary component 3 is provided on the mounting plate 21, and the auxiliary component 3 includes: a U-shaped plate 31, fixedly connected to the outer wall of the mounting plate 21; an extrusion block 32, slidably connected to the inside of the U-shaped plate 31; a second spring 33, provided inside the U-shaped plate 31, and with both ends fixedly connected to the outer wall of the extrusion block 32 and the inside of the U-shaped plate 31 respectively; a pull rod 34, fixedly connected to the outer wall of the extrusion block 32, and slidably connected to the U-shaped plate 31; air vents 4 are provided on both the U-shaped plate 31 and the extrusion block 32, and multiple air vents 4 are provided; a placement plate 5 is fixedly connected to the outer wall of the mounting plate 21; and friction patterns are provided on the outer wall of the gear ring 22.

[0033] When installing the mesh cover 13, the operator pulls the pull rod 34 to drive the extrusion block 32 into the interior of the U-shaped plate 31, and drives the extrusion block 32 to squeeze the spring 2 33. Then the operator places the mesh cover 13 on the inside of the U-shaped plate 31, and then the operator releases the pull rod 34. The spring 2 33 drives the extrusion block 32 to squeeze the mesh cover 13. The mesh cover 13 is pre-fixed by the extrusion block 32 to prevent the operator from rotating the gear ring 22 to install the mesh cover 13. It is inconvenient to press the mesh cover 13 with one hand and rotate the gear ring 22 with the other hand, thereby improving the convenience of the device; the U-shaped plate 31 and the extrusion block 32 are both provided with air vents 4, so that the airflow generated by the rotation of the blade body 12 can be discharged through the air vents 4, reducing the installation of the U-shaped plate 3 1, which affects the normal exhaust of the device, thereby improving the stability of the device; the outer wall of the mounting plate 21 is fixedly connected to the placement plate 5, and the operator passes the mesh cover 13 through the U-shaped plate 31 and contacts the placement plate 5. After the mesh cover 13 is placed on the placement plate 5, the mesh cover 13 can be placed in the correct position through the positioning of the placement plate 5, so that the operator does not need to spend time looking for the correct installation position, thereby improving the work efficiency of the operator; the outer wall of the gear ring 22 is provided with friction grooves, and when the operator rotates the gear ring 22 by hand, the friction grooves can increase the friction between the gear ring 22 and the operator's palm, thereby reducing the slippage of the operator's palm when rotating due to the smooth surface of the gear ring 22, thereby improving the stability of the device.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
