Abstract

The utility model discloses a fan blade which comprises a blade, a connecting piece connected with the blade through a fixing device, and a positioning device for positioning the blade and the connecting piece. The fixing device comprises a cupboard button and a knob; a detention table is arranged on the inner wall of cupboard button, an L-shaped groove matched with the detention table is arranged on the surface of a stem, the detention table can be embedded in the groove, and the cupboard button and the knob can be locked or separated through turning the cupboard button. In addition, a damper is arranged between the blade and the connecting piece. During use, the damper can automatically correct the deflection of the blade and a motor, thereby bringing about the steadier rotating speed of a fan. Simultaneously, due to the sound absorption of the damper, the fan does not give off vibratory noise during the working process, thereby improving the service life of the motor, reducing use cost, bringing about quick and easy assembly and disassembly, and saving time. Ordinary persons can assemble the blade with much convenience in assembly and transportation.

Description

A kind of electric fan

Technical field

The utility model relates to a kind of fan, particularly a kind of electric fan and linkage structure in flakes.

Background technique

At present, its flabellum of fan on the market roughly has three kinds of structures with being connected in flakes: the one, by rivet together, the 2nd, link together by bolt, the 3rd, directly weld together, and these three kinds of structures make flabellum with non-dismountable or dismounting is inconvenient in flakes, during installation fee, and need the professional and technical personnel to adjust the swing of flabellum and motor, this brings many inconvenience usually for assembling, transport.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of reliable, dismounting and electric fan easy for installation of using.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of electric fan, comprise flabellum, by fixing device be connected with flabellum in flakes and to flabellum and the positioning device that positions in flakes, flabellum and be respectively arranged with hole and flabellum hole in flakes in flakes, the knob that described fixing device comprises spinner and interts in hole and flabellum hole in flakes and be complementary with spinner, wherein knob comprises that one can lean at flabellum or surperficial in flakes jacking block, jacking block is provided with the stem stem that can insert in the spinner, the spinner inwall is provided with Ka Tai, the stem stem surface is provided with " L " type groove that matches with Ka Tai, Ka Tai can be embedded in the groove, and the locking that can realize spinner and knob when rotating spinner with separate.

As further improvement of the utility model, described flabellum and in flakes between the shock-absorbing sheet is installed, the shock-absorbing sheet is provided with the mounting hole that matches with hole in flakes.

The beneficial effects of the utility model are: the knob that fixing device of the present utility model comprises spinner and interts in hole and flabellum hole in flakes and be complementary with spinner, wherein knob comprises that one can lean at flabellum or surperficial in flakes jacking block, jacking block is provided with the stem stem that can insert in the spinner, the spinner inwall is provided with Ka Tai, the stem stem surface is provided with " L " type groove that matches with Ka Tai, Ka Tai can be embedded in the groove, and the locking that can realize spinner and knob when rotating spinner with separate; In addition, flabellum and in flakes between the shock-absorbing sheet is installed, in use the shock-absorbing sheet makes rotation speed of the fan more stable from the beat of normal moveout correction flabellum and motor, simultaneously because the sound absorption of shock-absorbing sheet, can not send the sound of vibration in the fan work process, increased motor life-span, reduced user cost, its dismounting and rapidity, convenience are installed is saved time, the ordinary person also can install, and brings many convenience for assembling and transport.
