Abstract
The utility model discloses an electric fan comprising a motor, a motor shaft and fan blades, wherein the fan blades are arranged on the motor shaft; a pin is arranged between the fan blades and the motor shaft; and the pin is inserted in a pin hole on the motor shaft. The utility model is characterized in that the diameter of the right end and the left end of the pin is smaller than that of the middle section; the pin is in a cylinder hollow wall structure, and a groove is arranged on the longitudinal direction of a cylinder hollow wall; the pin is embedded and tightly arranged in the pin hole through the middle section; and the pin is made of manganese steel material. The diameter of the right end and the left end of the pin on the motor shaft in the electric fan is smaller than that of the middle section, the pin is in the cylinder hollow wall structure, the groove is arranged on the longitudinal direction of the cylinder hollow wall, and the pin is embedded and tightly fixed in the pin hole through the middle section when in arrangement. The pin in the structure is very convenient to arrange, and can not fall off. Because the pin is made of the manganese steel material, the pin is convenient to maintain; the balance of two sides of each fan blade can be kept; and meanwhile the elastically is enough, so the pin is more convenient to be tightly fixed in the pin hole.
Description
Technical field
The utility model relates to a kind of electric fan, specifically the pin on the motor shaft in the electric fan is carried out improved technology.
Background technique
At present, the part of shaking the head of electric fan mainly is made up of motor, motor shaft and flabellum, and motor shaft is installed on the motor, and the driven by motor motor shaft rotates.Flabellum is installed on the motor shaft, in the position that motor shaft and flabellum join one pin is installed laterally, the middle end of pin is positioned at the pin hole on the motor shaft, and the two ends of pin are positioned at the protruding colored groove on the middle axial wall of flabellum, and the main effect of pin is to prevent that flabellum from rotating on motor shaft.Existing pin mainly contains three kinds of structures, and a kind of is cylindrical body, about diameter with the centre the same; Another kind is big, a little structure, and this pin is installed more convenient; Also has a kind of circular body that is, the middle cost that protrudes.All there is different shortcomings in the pin of these three kinds of structures: first kind of cylinder hollow steel body pin exists installs inconvenience, the dismounting maintenance is cumbersome, in addition, because pin is a steel body material, motor shaft also is a steel body material, and in use, it is big that the pin hole on the motor shaft can become, thereby cause pin that imprecision is installed, influence the quality of product; Second kind of pin be because of big, a minor structure, installs more conveniently, but occurs coming off, becomes flexible phenomenon easily in installation, transportation, maintenance process; The third pin exists installs very inconvenient shortcoming, is difficult to that promptly pin is aimed at protruding colored groove and squeezes into, and also protruding colored groove might be damaged even pack into by force, and when loading and unloading once more and keeping in repair, and can occur loosening and produces quality problems.
Summary of the invention
The purpose of this utility model provides and a kind ofly can make the electric fan that pin is easy for installation and improve the quality of products.
The purpose of this utility model is to realize like this.
A kind of electric fan, comprise motor, motor shaft and flabellum, flabellum is installed on the motor shaft, is provided with pin between flabellum and the motor shaft, pin is inserted in the pin hole on the motor shaft, and it is characterized in that: described pin is the pin of two, left and right sides diameter less than the intermediate section diameter.
Described pin is a column hollow wall construction, and the longitudinal direction of column hollow wall has groove.
Described pin embeds fastening being installed in the pin hole by intermediate section.
Described pin is made by the manganese steel material.
The utility model compared with prior art has the following advantages:
Pin in the utility model electric fan on the motor shaft is the pin of two, left and right sides diameter less than the intermediate section diameter, and pin is a column hollow wall construction, and the longitudinal direction of column hollow wall has groove, embeds fastening being installed in the pin hole by intermediate section when mounted.The pin of this structure is installed very convenient, and can not come off.Owing to make with the manganese steel material, be convenient to maintenance, can keep flabellum both sides balance, simultaneously, elastic force is pure, and the pin of being more convenient for is fastened in the pin hole.
Description of drawings
Fig. 1 is the structure for amplifying schematic representation of the utility model pin;
Fig. 2 is installed in structural representation on the motor shaft for the utility model pin.
Embodiment
Below in conjunction with accompanying drawing the concrete real mode example of the utility model is elaborated.
As Fig. 1 and shown in Figure 2, the pin 1 on the utility model motor shaft is cylindric hollow wall construction, and pin 1 is made up of the three sections cylindrical bodys in left center right, about two sections cylindrical diameter identical, the diameter of intermediate section greater than about the cylindrical diameter of section.The longitudinal direction of pin 1 has the groove of indentation.Pin 1 is made by the manganese steel material.When mounted, the intermediate section of pin 1 is embedded in the pin hole that is installed on the motor shaft 2,,, utilize this tension force, pin 1 is fastened in the pin hole when it inwardly shrinks the tension force that the back existence expands outwardly because intermediate section is the hollow wall construction.Pack in the protruding colored groove on the axial wall of flabellum center in the two ends of pin 1.After the installation, can make flabellum and motor shaft 2 keep relatively-stationary position, flabellum can not rotated on motor shaft 2.Not only easy installation and removal of pin 1 on the utility model motor shaft, and can securely being installed in the pin hole on the motor shaft 2, the phenomenon that can occur coming off has not improved the quality of product.
Claims (3)
1. electric fan, comprise motor, motor shaft and flabellum, flabellum is installed on the motor shaft, is provided with pin between flabellum and the motor shaft, pin is inserted in the pin hole on the motor shaft, and it is characterized in that: described pin is the pin of two, left and right sides diameter less than the intermediate section diameter.
2. electric fan according to claim 1 is characterized in that: described pin is a column hollow wall construction, and the longitudinal direction of column hollow wall has groove.
3. electric fan according to claim 1 is characterized in that: described pin embeds fastening being installed in the pin hole by intermediate section.
