Description
Technical field
The utility model relates to a kind of anti-dropout pivot structures for fan, belong to fan structure connector technology
Field.
Background technique
Existing small-sized fans, such as dedicated for the fan for carrying out heat transmission in computer housing, he includes one rectangular outer
Shell, inside are fixedly installed with rotatable wind wheel by shaft warp beam sleeve, but with the continuous rotation of wind wheel, wind wheel and shaft
Between fixation can be easy to happen loose or dislocation because of the rotation of wind wheel, and used shaft is conventional shaft, nothing in structure
Method guarantees the fastness of connection.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and it is simple to provide a kind of structure, uses peace
Dress is conveniently used for the anti-dropout pivot structure of fan.
The purpose of this utility model is completed by following technical solution, a kind of anti-dropout shaft knot for fan
Structure, it includes a shaft, and one end end surface jackshaft of the shaft is screwed on to being provided with threaded hole in the threaded hole
There is a screw fastening end cap for fixing wind wheel component of configuration, the described screw fastening end cap can be in screw thread hole by front end
The circular ring shape end cap that screw or screw rod and rear end integrally form is constituted, the steering of thread rotary orientation and shaft in the threaded hole
It is reversed.
As preferred: the chamfered annulus in outer ring of the circular ring shape end cap, and it is outer small interior big, adjacent to the interior big of roller end
Diameter is not more than the diameter of shaft；The other end of the shaft is provided at least one positioning ring recess for mating retainer ring.
The features such as the utility model belongs to improvements over the prior art, it has structure simple, easy to install and use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 1, a kind of use described in the utility model
In the anti-dropout pivot structure of fan, it includes a shaft 1, and one end end surface jackshaft of the shaft 1 is to being provided with spiral shell
Pit 2, and it is screwed in the threaded hole 2 the screw fastening end cap 3 for fixing wind wheel component of configuration, the screw fastening
End cap 3 by front end can the circular ring shape end cap 5 that integrally forms of screw in screw thread hole or screw rod 4 and rear end constitute, it is described
The steering of thread rotary orientation and shaft 1 in threaded hole 2 is reversed, to guarantee that screw fastening end cap 3 and the connection of shaft 1 are got over
Rotation more fastens.
As shown in the figure, the chamfered annulus in outer ring of circular ring shape end cap 5 described in the utility model, and it is outer small interior big, it is neighbouring to turn
The interior major diameter of 1 end of axis is not more than the diameter of shaft 1；The other end of the shaft 1 is provided at least one for mating card
The positioning ring recess 6 of circle.
