Abstract
The utility model embodiment discloses a kind of electric fan new line shaft, comprising: bracket, the bracket are U-shaped, and upper part is equipped with the positioning shaft hole of a pair of of alignment；Locating shaft, the locating shaft pass through the positioning shaft hole of bracket, and locating shaft is flat, and one end is equipped with the cylindrical structure that diameter is greater than locating shaft aperture, and the other end is equipped with axial trough；Snap ring, the snap ring are located at the axial trough of the side of locating shaft；Roll film, the roll film are fixed on the outside of locating shaft, when electric fan head comes back, are driven roll film rotation to loosen, are increased its tension, play the role of supporting electric fan head.The utility model structure is simple, is increasing the roll film opposite with dynamics when electric fan head new line in original shaft, when electric fan head comes back, with roll film inner tensions on the contrary, making electric fan head can be with easy adjustment to required pitch angle.
Description
Technical field
The utility model relates to electric fan shaft, specially a kind of electric fan new line shaft.
Background technique
Previous electric fan new line shaft, pitch regulation is unstable, and required dynamics is unbalanced, and electric fan new line is to pass through hand
Dynamic to adjust, undue force can damage electric fan head, and user experience is bad.Therefore our company determines that research new product solves this and asks
Topic.
Utility model content
The purpose of this utility model is to provide a kind of electric fan new line shafts, mitigate pitch of head of electric fan and adjust when institute
The dynamics needed realizes that user's operation is exerted oneself lightweight.
To achieve the above object, the utility model proposes a kind of electric fan new line shafts, comprising:
Bracket, the bracket are U-shaped, and upper part is equipped with the positioning shaft hole of a pair of of alignment；
Locating shaft, the locating shaft pass through the positioning shaft hole of bracket, and locating shaft is flat, and one end is equipped with diameter greater than fixed
The cylindrical structure of position aperture axis, the other end are equipped with axial trough；
Snap ring, the snap ring are located at the axial trough of the side of locating shaft；
Roll film, the roll film are fixed on the outside of locating shaft, when electric fan head comes back, are driven roll film rotation to loosen, are made it
Tension increases, and plays the role of supporting electric fan head.
Further, the bracket is respectively equipped with the position-limit mechanism of a locating shaft on the inside of two positioning shaft holes, described
It is equipped with flat through-hole and locating shaft among position-limit mechanism to cooperate, two sides are equipped with rectangular cylindrical structures to be fixed on bracket.
Further, the bracket is respectively equipped with the position restrainer of rectangular through-hole and locating shaft above and below positioning shaft hole
Rectangular cylindrical structures on structure match.
Further, the branch is provided with screw hole, is fixed by bolts in electric fan base.
Further, the snap ring is specially E shape snap ring.
Compared with prior art, the utility model has the beneficial effects that the utility model increases and electricity in original shaft
Dynamics opposite roll film when fan head comes back, when electric fan head comes back, with roll film inner tensions on the contrary, making electric fan machine
Head can be with easy adjustment to required pitch angle.Conversely, generating compression to roll film when electric fan head is bowed, roll film is continued to rotate
It is obstructed, forms position-limiting action.Realize positioning function.Damping dynamics and any position needed for the utility model meets each side are fixed
Bit function improves the service life of product, increases practical performance.
Detailed description of the invention

Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
It mutually combines, the utility model is described in further detail in the following with reference to the drawings and specific embodiments.
If directional instruction (such as up, down, left, right, before and after ...) is only used for explaining in the utility model embodiment
In relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, if the specific appearance
When state changes, then directionality instruction also correspondingly changes correspondingly.
If in addition, the description for being related to " first ", " second " etc. in the present invention is used for description purposes only, and cannot manage
Solution is its relative importance of indication or suggestion or the quantity for implicitly indicating indicated technical characteristic.Define as a result, " the
One ", the feature of " second " can explicitly or implicitly include at least one of the features.
Please refer to Fig. 1 ~ 3, a kind of electric fan new line shaft, comprising:
Bracket, the bracket are U-shaped, and upper part is equipped with the positioning shaft hole of a pair of of alignment；
Locating shaft, the locating shaft pass through the positioning shaft hole of bracket, and locating shaft is flat, and one end is equipped with diameter greater than fixed
The cylindrical structure of position aperture axis, the other end are equipped with axial trough；
Snap ring, the snap ring are located at the axial trough of the side of locating shaft；
Roll film, the roll film are fixed on the outside of locating shaft, when electric fan head comes back, are driven roll film rotation to loosen, are made it
Tension increases, and plays the role of supporting electric fan head.
As an implementation, the bracket is respectively equipped with the position restrainer of a locating shaft on the inside of two positioning shaft holes
Structure, the position-limit mechanism centre are equipped with flat through-hole and locating shaft and cooperate, and two sides are equipped with rectangular cylindrical structures and are propped up with being fixed on
On frame.
As an implementation, the bracket is respectively equipped with rectangular through-hole and locating shaft above and below positioning shaft hole
Position-limit mechanism on rectangular cylindrical structures match.
As an implementation, the branch is provided with screw hole, is fixed by bolts in electric fan base.
As an implementation, the snap ring is specially E shape snap ring.
When electric fan head comes back, with roll film inner tensions on the contrary, making electric fan head can be with easy adjustment needed for
Pitch angle.Conversely, generating compression to roll film when electric fan head is bowed, roll film, which continues to rotate, to be obstructed, and forms position-limiting action.It is real
Existing positioning function.Damping dynamics and any position positioning function needed for the utility model meets each side, improve the longevity of product
Life increases practical performance.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
