Improved structure of fan bearing

Abstract

This invention relates to a structural improvement of a fan bearing seat. A bearing seat is provided within the housing of a frame, and a bearing for assembling a fan is assembled into the inner hole of the bearing seat. The assembly section at the bottom of the bearing seat has multiple insertion slots, each with a locking channel surrounding the bearing seat on one side. A screw cap is then assembled in the assembly section, and the screw cap abuts against the bottom edge of the bearing. The body of the screw cap stops at the bottom of the inner hole of the bearing seat. Multiple wing plates are provided around the body, allowing for alignment and locking into each insertion slot. The screw cap then rotates radially around the center of the bearing seat and slides to each locking channel. The side edges of each wing plate act as locking parts, abutting against the end of each locking channel to form a limit. An operating section is provided on the body for operation with a pre-set hand tool, facilitating the assembly or disassembly of the bearing at the bearing seat via the screw cap.

Claims

1. An improved structure of a fan bearing housing, comprising a frame, a bearing housing located inside the frame, and a screw cap assembled at the bearing housing, wherein: The frame has an internal accommodating space, and within this accommodating space is a bearing seat for assembling a pre-set fan shaft. The bearing seat has an inner hole for assembling the shaft, and at the bottom of the bearing seat on one side of the inner hole, there is an assembly part with a plurality of insert slots. Each insert slot of the assembly part has a locking channel surrounding the bearing seat. The cap is assembled at the assembly part of the bearing seat and abuts against the end edge of the shaft. It includes a body that stops at the bottom of the inner hole of the bearing seat, a plurality of wing plates located around the periphery of the body for alignment and locking into each insert slot, and then rotating around the center of the bearing seat and sliding to each locking channel. The side edge of each wing plate has a locking part that abuts against the end of each locking channel. The body also has an operating part for a pre-set hand tool to operate its rotation.

2. The improved structure of the fan bearing as described in claim 1, wherein the assembly part provided at the bottom of the bearing of the frame includes at least three or more fan-shaped insert grooves, and each insert groove has a locking channel cut along the same axis on its inner side. A predetermined width of isolation section is formed between the end of each locking channel and the adjacent insert groove. At least two or more fan-shaped wing plates are provided around the periphery of the cap, for each wing plate to be aligned and locked into each insert groove.

3. The improved structure of the fan bearing as described in claim 1, wherein the assembly part provided at the bottom of the bearing of the frame is provided with a plurality of recessed grooves that are recessed inward from the bottom of the bearing, and each recessed groove is provided with a locking channel.

4. The improved structure of the fan bearing as described in claim 1, wherein the thickness of the cap is less than the groove depth of each locking channel, and there is a height difference between the center and the periphery of the cap plane to ensure that the cap can be tightly inserted into the locking channel.

5. The improved structure of the fan bearing as described in claim 1, wherein the swivel cover has a locking portion protruding from the surface of each of the blades in the shape of an arc, a column, or a polygon.

6. The improved structure of the fan bearing as described in claim 1, wherein the cap is made of metal and the body has at least one or more operating parts in the form of a groove, hole or protrusion, for the corresponding preset hand tool to operate the operating parts to drive the cap to rotate.

7. The improved structure of the fan bearing as described in claim 6, wherein the operating part is in the form of a slot, cross slot, polygonal slot or round hole, rectangular hole, polygonal hole or round rod, quadrilateral rod or polygonal rod, so that the operating part can be operated by the corresponding screwdriver, wrench, jig or ratchet wrench.
