Description
Technical field
The utility model relates to a kind of fan structures, and in particular to a kind of mounting structure of fan connecting rod and pedestal.
Background technique
Fan generally includes fan main body, fan connecting rod and pedestal, and fan main body is mounted on the top of fan connecting rod, fan
The bottom of connecting rod is connected on pedestal.Since fan length of connecting rod is larger, the torque that fan main body is formed is very big, thus it requires
The bonding strength of fan connecting rod and pedestal is very high, is not so easy to appear the situations such as shaking or fan link tilt.Currently, fan
The connection type of connecting rod and pedestal is plug in construction, is equipped with connecting hole at the middle part of pedestal, the bottom insertion of fan connecting rod should
Blending bolt is fixed in connecting hole, although the structure has many advantages, such as that structure is simple, convenient for disassembly and assembly, its tightness connected
Not enough, there are biggish joint gaps, and fan can generate vibration and noise when rotating, especially after being dismounted for multiple times, vibration
It is more obvious with noise.
Utility model content
One kind that in order to overcome the deficiencies of the prior art, the utility model provides is structurally reasonable, degree of being completely embedded is high, dismounting
The mounting structure of convenient fan connecting rod and pedestal.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of mounting structure of fan connecting rod and pedestal, including fan connecting rod and discoid pedestal, in the pedestal
Portion is equipped with the connection through-hole connecting with fan connecting rod, and the aperture of the connection through-hole gradually decreasees from top to bottom, and the fan connects
The bottom of bar is the cone cell that diameter is gradually reduced, and the convex ribs of a plurality of protrusion, institute are arranged at intervals on the inner wall of the connection through-hole
The side wall that convex ribs withstand on fan connecting rod bottom is stated, the bottom of the pedestal is equipped with fixing bolt, fixed spiral shell is equipped in fan connecting rod
Line connector, fixing bolt are inserted into out of connection through-hole and are connected on fixed thread connector.
In the present invention, it raises upward to form rotary table in the middle part of the base upper surface.
In the present invention, the height of the rotary table is greater than base diameter 1/10th.
In the present invention, the upwardly recessed formation pit in the middle part of the base lower surface.
In the present invention, the pedestal includes base body and the lid shell for covering on base body upper surface.
The beneficial effects of the utility model are: the connection through-hole diameter of the utility model is gradually reduced, fan connecting rod and bottom
Being connected under the action of fan main body and motor vibration for seat can be fastened increasingly, and connective stability is high, even across repeatedly tearing open
Dress is also able to maintain preferable cooperation；Further, the convex ribs that a plurality of protrusion is arranged at intervals on the inner wall of through-hole are connected, convex ribs withstand on wind
The side wall for fanning connecting rod bottom, by the cooperation of convex ribs and fan rod surface, reduction fan rod surface with connect through-hole wall
Contact area, reduce frictional force, be difficult to the phenomenon that extracting when avoiding the occurrence of disassembly；Further, the middle part of base upper surface
It raises upward to form rotary table, connection through-hole is located at the middle part of rotary table, and raised height increases connection through-hole and fan connecting rod
Length of fit keeps its buckle resistance more preferable.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the present embodiment；
Fig. 2 is A-A sectional view of Fig. 1；
Fig. 3 is the structural schematic diagram of pedestal；
Fig. 4 is the cross-sectional view of pedestal；
Fig. 5 is the cross-sectional view of shell pedestal with cover.
Specific embodiment
Referring to figs. 1 to Fig. 4, a kind of mounting structure of fan connecting rod and pedestal provided by the present embodiment, including fan connect
Bar 1 and discoid pedestal 2, the pedestal 2 are made of plastics and are solid construction, have the effect of clump weight.The bottom
The middle part of seat 2 is equipped with the connection through-hole 3 connecting with fan connecting rod 1, and the aperture of the connection through-hole 3 gradually decreasees from top to bottom,
Its gradient is greater than 1/10 less than 1/3, and too small gradient is easy to cause fan connecting rod 1 to penetrate and connects through-hole 3, and excessive gradient
It is easy to cause connection unstable, the bottom of the fan connecting rod 1 is the cone cell that diameter is gradually reduced.The inner wall of the connection through-hole 3
On be arranged at intervals with six to eight raised convex ribs 4, the height of 4 protrusion of convex ribs is 1-2mm, and the convex ribs 4 withstand on fan
The side wall of 1 bottom of connecting rod.The bottom of the pedestal 2 is equipped with fixing bolt 5, and the bottom of the fan connecting rod 1 is thin-walled tubular knot
Structure fills in fixed thread connector 6 in pipe, the bottom of pipe is then pressed into frustum and wraps fixed thread connector 6 passes through weldering again
Connect fixation, when installation, after fan connecting rod 1 is inserted into connection through-hole 3, fixing bolt 5 is inserted into and is connected to from connection 3 bottom of through-hole
On fixed thread connector 6.
As preferred embodiment, raise upward to form rotary table 7 in the middle part of 2 upper surface of pedestal, the rotary table 7 and bottom
Seat 2 is integrally formed and outer ring is transition circle arcuation, and the height of the rotary table 7 is greater than 2 diameter 1/10th of pedestal, raised height
Degree increases the length of fit of connection through-hole 3 and fan connecting rod 1, keeps its buckle resistance more preferable.In 2 lower surface of pedestal
The upwardly recessed formation pit 8 in portion, the depth of the pit 8 are greater than the thickness on 5 head of fixing bolt, avoid 5 head of fixing bolt
