Problems solved by technology

However, for micro fans, there is generally no matching buckle or fan frame without barbs to limit the fan rotor, and there is no buckle or buckle to limit the wire, so it is impossible to effectively prevent the rotor from being damaged. Flying out of the fan frame and fixing wires

Embodiment Construction

[0034] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

Abstract

The invention relates to a rotor dash-off preventing and wire clamping structure for an axial-flow fan, which comprises a first fan frame and a second fan frame. On the premise of not changing the design of a fan, the fan frame of the axial-flow fan is disassembled to form the first fan frame and the second fan frame. An accommodation hole is formed in the middle of the first fan frame, and the inside wall of the accommodation hole protrudes to form a convex part which can effectively prevent a fan rotor from dashing off. The second fan frame and the first fan frame are connected in the way that positioning posts and positioning holes are matched with each other, at least one wire clamping groove is formed after the positioning posts and the positioning holes are matched, and wires connected with a circuit board can be clamped in the wire clamping grooves, so that limiting and fixing of the wires are completed, the wires are effectively prevented from getting loose, the consumption of glue is reduced and the material cost is lowered. As the first fan frame and the second fan frame are assembled, the fan assembly process is simplified on the premise of not influencing the properties of the fan, the difficulty in producing a micro-fan is effectively reduced, and the production efficiency and yield are improved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an axial flow fan and its rotor flying-out preventing and wire-clamping structure. Background technique [0002] Fans can be divided into two types: axial flow and radial flow, which are divided according to the flow direction of the air when the fan is working: when the axial flow fan is working, the blades push the air to flow in the same direction as the shaft, so it is called an axial flow fan; When the radial fan works, the blades push the air to flow in a direction perpendicular to the axis (that is, radial direction), so it is called a radial fan. [0003] Most of the traditional axial flow fans have a groove on the axis of the rotor. When the fan is assembled, the groove on the axis of the rotor is either buckled with the buckle, or buckled with the barb on the fan frame to secure the fan. The rotor is limited so that it will not fly out of the fan body; and the wire is lim...
