Abstract
The utility model relates to a connecting mechanism for connecting a fan rear casing with a motor casing, which is characterized in that the connecting mechanism comprises a connecting support which is engaged with the fan rear casing, a supporting arm and a hole which can be penetrated by a motor shaft are arranged on the connecting support, the connecting support is equipped with a mounting hole which can be penetrated by a connecting screw bolt and a mounting hole of the supporting arm, the two mounting hole mutually correspond, and thereby the fan rear casing and the motor casing are connected via the screw bolt. The connecting mechanism structure has the function of heat insulation, and parts such as impellers and the like can be mounted in an inner chamber of the structure, which is in favor of heat insulation of the motor, thereby achieving the purpose of increasing the service life of the motor with low cost.
Description
Technical field
The utility model relates to a kind of bindiny mechanism that blower fan back cover and motor casing are used that connects.
Background technique
The prior motor shell is directly to be fixed on the blower fan back cover, and motor is a natural heat dissipation, and itself does not have sink yet.And when entering Blower Housing, can directly pass to motor to heat as hot blast (heat).This structure is very unfavorable to motor radiating, thereby influences the operating life of motor.
The model utility content
The utility model is to overcome the deficiencies in the prior art and a kind of bindiny mechanism that blower fan back cover and motor casing are used that connects is provided, because this bindiny mechanism has been arranged, played heat insulation effect, and component as impeller and so on can be installed at this structure inner chamber, heat radiation to motor is very favourable, has reached the purpose that little cost just can improve electrical machinery life.
In order to achieve the above object, the utility model is to realize like this, it is a kind of bindiny mechanism that blower fan back cover and motor casing are used that connects, it is characterized in that: comprise the support that is connected with the cooperation of blower fan back cover, be provided with the hole that support arm and motor shaft can pass on the support connecting, be provided with the mounting hole that connecting bolt can pass and the mounting hole of support arm on the support connecting; The position of two mounting holes in correspondence with each other, thereby blower fan back cover and motor casing are connected by bolt.
On described connection support, also be provided with passive support block or support tube, on support block, be provided with the hole that connecting bolt can pass; Described support arm is " 7 " font.
On the side of described support arm, also be provided with the installing and locating hole, thereby can itself and heat radiation protective net be fixed by bolt.
Thereby being provided with the flange edge at described connection support at opening end makes connection support rigidity stronger.
The utility model advantage compared with prior art is, this structure has played heat insulation effect, and at this structure inner chamber component as impeller and so on can be installed, and is very favourable to the heat radiation of motor, reached the purpose that little cost just can improve electrical machinery life.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is an A-A sectional view of the present utility model;
Fig. 3 is a stereogram of the present utility model;
Fig. 4 is that the utility model is installed in the structural representation on the blower fan.
Embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
Shown in Fig. 1 to 4, it is a kind of bindiny mechanism that blower fan back cover and motor casing are used that connects, comprise with blower fan back cover 6 cooperates and be connected support 1, on the connection support, be provided with the hole 11 that support arm 2 and motor shaft can pass, on connection support and support arm, be provided with the mounting hole 12 and 21 that connecting bolt can pass; The position of two mounting holes in correspondence with each other, thereby blower fan back cover and motor casing are connected by bolt; Support arm is " 7 " font.In the present embodiment, on connection support 1, also be provided with passive support block 3, on support block, be provided with the hole 31 that connecting bolt can pass, thereby play the effect of strengthening and supporting; On support arm, also be provided with positioning hole 22, thereby can itself and heat radiation protective net be fixed by bolt; Connect support and be provided with flange edge 13, thereby make connection support rigidity stronger at opening end.
