Abstract
The utility model provides a connecting structure for a rear heat radiating cover of a fan, which is reasonable in structure, convenient to machine and stable to connect. The connecting structure comprises a motor shell and a rear heat radiating cover, wherein a plurality of threaded holes are formed at the rear end of the side surface of the motor shell; a plurality of connecting holes corresponding to the threaded holes are formed at the front end of the side surface of the rear heat radiating cover; and the front end of the rear heat radiating cover is sleeved on the rear end of the motor shell and is fixed through bolts. According to the connecting structure provided by the utility model, the threaded holes and bolts at the rear end of the side surface of the motor shell are directly connected with the rear heat radiating cover. Compared with the traditional structure, the connecting structure provided by the utility model has the advantages of simple structure, convenience and quickness for mounting, reduced intermediate connecting pieces, capabilities of reducing production cost and increasing production efficiency, stable and firm connection, reduced vibration and long service life.
Description
Technical field
The utility model relates to a kind of fan, is specifically related to the linkage structure of dissipating cover behind a kind of fan.
Background technique
The family expenses fan generally is made up of flabellum, fan guard and motor, and the front portion of motor is provided with the fan cover that is connected with fan guard, and the rear portion of motor is connected with the back dissipating cover.In the existing technology; Interconnect through L type connecting sheet between motor and the back dissipating cover; Edge at the ear end face of motor casing is drilled with tapped hole, and L type connecting sheet is through on the ear end face that is bolted to motor casing, and the front end of back dissipating cover side is provided with a plurality of attachment holes; Screw passes attachment hole and is connected with L type connecting sheet, thereby the back dissipating cover is fixed on the motor.
Because motor interconnects through intermediate connector (being L type connecting sheet) between the dissipating cover with the back, the centre how individual parts, not only increase processing cost, need more manpower and materials, and connective stability is not high, the probability that increase goes wrong.
Summary of the invention
In order to overcome the deficiency of existing technology, the utility model provides a kind of rational in infrastructure, easy to process, linkage structure of connecting dissipating cover behind the stable fan.
The utility model solves the technological scheme that its technical problem adopted:
The linkage structure of dissipating cover behind a kind of fan; Comprise motor casing and back dissipating cover; The rear end, side of said motor casing is provided with a plurality of tapped holes; The side front end of back dissipating cover is provided with a plurality of and the corresponding attachment hole of tapped hole, and the front end sleeve of back dissipating cover is located on the rear end of motor casing and passes through bolt.
In the utility model, the rear end, side of said motor casing is provided with the step that concaves, and tapped hole is positioned on the step, and the front end sleeve of back dissipating cover is located on the step.
In the utility model, the edge of said motor casing ear end face is provided with the annulus to outer lug, and tapped hole is positioned at the side of this annulus.
In the utility model, the ear end face of said annulus is provided with a plurality of positioning holes.
The beneficial effect of the utility model is: the utility model directly is connected with the back dissipating cover with bolt at the tapped hole of rear end, motor casing side, compares with traditional structure, and it is simple in structure; Easy for installation, quick, reduce intermediate connector, reduce production costs; Enhance productivity; And it is firmly firm to connect, and reduces vibrations, long service life.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is further specified:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the explosive view of Fig. 1;
Fig. 3 is another angle explosive view of Fig. 1.
Embodiment
Referring to figs. 1 through Fig. 3; That present embodiment provided was a kind of rational in infrastructure, easy to process, connect the linkage structure of dissipating cover behind the stable fan; Comprise motor casing 1 and back dissipating cover 2; The rear end, side of said motor casing 1 is provided with a plurality of tapped holes 11, and the side front end of back dissipating cover 2 is provided with a plurality of and tapped hole 11 corresponding attachment holes 21, and the front end sleeve of back dissipating cover 2 is located on the rear end of motor casing 1 and through bolt 3 and fixes.
As preferred embodiment; The rear end, side of said motor casing 1 is provided with the step 12 that concaves, and tapped hole 11 is positioned on the step 12, and the front end sleeve of back dissipating cover 2 is located on the step 12; The front-end face of back dissipating cover 2 is against on the facade on step 12 next doors, plays the effect of axially locating.
Further, for ease processing with do not influence machine operation, the edge of said motor casing 1 ear end face is provided with the annulus 13 to outer lug, tapped hole 11 is positioned at the side of this annulus 13.Simultaneously, the excircle diameter of annulus 13 is less than the excircle diameter of motor casing 1, thus formation step 12.Circumferential location for ease, the ear end face of said annulus 13 is provided with a plurality of positioning holes 14, can with the cooperatively interacting of inboard locating stud of back dissipating cover 2 and so on, further facilitate and install and maintenance.
The above is merely the preferential mode of execution of the utility model, as long as realize that with basic identical means the technological scheme of the utility model purpose all belongs within the protection domain of the utility model.
