Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fans, in particular to an assembly structure of an axial flow fan. Background Art

[0002] An axial flow fan is a fluid machine that uses a rotating impeller to increase the speed and pressure of the fluid. The working principle of this fan is to use an electric motor to drive the impeller to rotate. The blades on the impeller exert pressure on the gas during rotation, causing the gas to move along the axial direction of the impeller. The gas flow direction in the axial flow fan is parallel to the axis of the fan, which is why it is called "axial flow".

[0003] The existing patent number CN219013003U discloses an axial flow fan that is easy to assemble, and relates to the technical field of axial flow fans, including a connecting box, a positioning column is arranged on the side of the connecting box, a louver fan is arranged in the middle of the connecting box, and installation grooves are provided in the internal openings at the upper and lower ends of the connecting box, and limiting grooves are provided at both ends of the installation groove. A rotating bracket is arranged inside the installation groove, and a connecting rod is arranged on the outside of the rotating bracket. A pressing head is installed at one end of the connecting rod, and a reset spring is arranged on the outside of the pressing head. The utility model presses the pressing head first to move one end of the connecting rod downward, thereby lifting the fixed head at the other end, and then the connecting box can be sleeved on the outside of the connecting frame, and then the pressing head is released, and the reset spring will push the fixed head to move downward, allowing it to enter the inside of the fixing hole, thereby connecting the connecting box and the mounting frame together. This is convenient and quick to install, can reduce installation time, and improve efficiency.

[0004] The prior art disassembly is performed by pressing a pressing head. When an object is placed on the upper surface of the fan, the object will hit the pressing head, causing the connection box to be automatically disassembled, thereby causing the blinds to fall off from the mounting frame, exposing the fan blades. Not only will the fan blades be unprotected, but the rotating fan blades will also create a safety hazard. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

[0031] The structural unit 200 includes lower arc plates 201 arranged on both sides of the support plate 103, the upper sides of the two groups of lower arc plates 201 are fixedly connected to upper arc plates 202, and the upper arc plates 202 are movably connected to the support plate 103, and protective nets 204 are fixedly connected between the two groups of lower arc plates 201 and the upper arc plates 202, the upper surfaces of the two groups of upper arc plates 202 are movably connected to arc clamping plates 205, and one end of the arc clamping plate 205 is rotatably connected to a fixed seat 203, the fixed seat 203 is fixedly connected to a group of support plates 102, and the other end of the arc clamping plate 205 is provided with a locking assembly 206, and the upper sides of the two groups of upper arc plates 202 are fixedly connected to handles 207.

[0032] Among them, the locking assembly 206 includes a connecting block 206a fixedly connected to the other end of the arc-shaped clamping plate 205, and the outer side of the connecting block 206a is locked and connected with a locking seat 206b, the locking seat 206b is fixedly connected to another support plate 102, and the inside of the locking seat 206b is slidably connected with an insertion rod 206c, and the insertion rod 206c is slidably connected to the connecting block 206a. By slidingly connecting and locking the insertion rod 206c with the connecting block 206a and the locking seat 206b, the arc-shaped clamping plate 205 can fix the upper arc plate 202.

[0033] Furthermore, one end of the insertion rod 206c is fixedly connected to a circular plate 206d, and the circular plate 206d is fixedly connected to a spring 206e on one side of the insertion rod 206c, and the other end of the spring 206e is fixedly connected to the locking seat 206b.
