Abstract

The utility model discloses a motor casing of ceiling fan formed by connection of an upper hood and a lower hood; the upper hood and the lower hood are formed by injection molding and are provided with reinforcing ribs from middle to circumference. The edge of the upper hood and the lower hood is provided with a connection hole. The edge of the center hole in the top part of the upper hood heaves and the part which heaves forms a positioning concave position of an upper bearing; the concave position is fixed with a bearing inside; the middle of the bottom of the lower hood is provided with a positioning concave position of a lower bearing. The upper hood and the lower hood of the utility model are both provided with a radiation hole and both appear a satellite dish shape structure. With above structure, the utility model has advantages of more convenient and fast installation, firm structure and low cost, etc., in addition, it is an ideal accessory structure of ceiling fan at present.

Description

The motor case cover of ceiling fan

Technical field

The utility model relates to ceiling fan, is specifically related to the motor case cover structure of ceiling fan.

Background technique

The jacket of its motor of ceiling fan of prior art generally adopts metallic plate punching to be shaped, it is made of two halves housing fit up and down, and last lower shell body is fastened together by screw, and the rotor of motor and stator place in this housing, have the hole in the middle of the upper encloser top, this hole is passed in rotating shaft.Though the motor housing case structure of said structure is comparatively firm, cost is higher, is difficult to guarantee shaft concentricity preferably, and the motor radiating effect is bad.As application number be 01224738, the applying date is that May 25 calendar year 2001, denomination of invention are the patent of the fixed structure of ceiling fan motor rotor and shell, the shell that it mainly includes motor rotor, stator and is combined by upper and lower cover body.Shell is provided with an apical axis hole in its top centre, and is reference point with the center in apical axis hole, and the pre-subpunch in appropriate position around it is recessed countersunk head groove, the certain embedding of formation district between each countersunk head groove and shell interior sidewall surface.Motor rotor is provided with hitching post in the appropriate position of each countersunk head groove of corresponding shell, and convexes with a location lug at the external side brim of hitching post.Though said structure has certain concentricity and locating effect, also increased the structural strength of shell simultaneously, complex structure, same cost is higher, the loading and unloading trouble, and also profile is stiff.

Summary of the invention

The purpose of this utility model is exactly to provide in order to solve above-mentioned deficiency a kind of sound construction, cost low, has the motor case cover structure of the ceiling fan of better concentricity and locating effect simultaneously.

In order to achieve the above object, the utility model has adopted following technical solution: the motor case cover of this ceiling fan is connected and composed by two cover caps up and down of injection molded, up and down in two cover caps from the middle part to around be equipped with stiffening rib, two cover cap edges have attachment hole up and down, upper cover top center nose end edge protuberance, the inner formation of its boss upper bearing (metal) location recess, the recess internal fixation has bearing, is being provided with lower bearing location recess in the middle of the cover cap inner bottom part down.

As the further improvement of such scheme, all have radiation hole on up and down two cover caps of the present utility model; Above-mentioned two cover caps up and down are the star disc structure.

Adopt said structure to the utlity model has following advantage:

1, sound construction is difficult for getting loose, the concentricity height; Rotor by motor is embedded in up and down between the cover cap by the stiffening rib button, stator is fixed by the bearing location recess of cover cap up and down, can effectively guarantee firm casing structure and motor rotor and stator concentricity preferably by its inner set stiffening rib again, it is more steady that ceiling fan is rotated.

2, loading and unloading are efficient and convenient, only need motor is fastened on up and down that the solid screw of spiral shell gets final product in the cover cap; Or adopt the upper and lower cover male and female mode of buckleing to link closely.

3, cost is low, makes simply, and cover cap up and down of the present utility model all can adopt the injection moulding single forming;

4, the utility model has adopted star disc structure, beautiful shape.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described

Fig. 1 is a form structure schematic representation of the present utility model;

Fig. 2 is the A-A sectional structure schematic representation of the utility model Fig. 1.

Embodiment

As Fig. 1-shown in Figure 2, the motor case cover of ceiling fan of the present utility model is connected and composed by two

cover caps

2,4 up and down of injection molded, all has radiation hole 5 on two

cover caps

2,4 up and down; Two

cover caps

2,4 are the star disc structure up and down; Up and down in two

cover caps

2,4 from the middle part to around be equipped with stiffening ribs 8,11, two cover caps, 2,4 edges have attachment hole 3 up and down, upper cover 2 top center nose end edge protuberance, the inner formation of its boss upper bearing (metal) 7 location recess 6, recess 6 internal fixation have bearing 7, are being provided with lower bearing 13 location recess 12 in the middle of cover cap 4 inner bottom parts down; Rotor 10 sides of motor all are located at step up and down, and stiffening rib 8,10 and step adapt rotor is fastened between two cover caps, by bolt and nut two cover caps are tightened together, and make the utility model sound construction, motor rotor, stator concentricity height.

Above-mentioned up and down two

cover caps

2,4 tighten together by screw, also can adopt to cover male and female mode up and down and be fastened together.

Claims

1, a kind of motor case cover of ceiling fan, two cover caps up and down by injection molded connect and compose, two cover cap edges have attachment hole up and down, it is characterized in that, up and down in two cover caps from the middle part to around be equipped with stiffening rib, upper cover top center nose end edge protuberance, the inner formation of its boss upper bearing (metal) location recess is being provided with lower bearing location recess in the middle of the cover cap inner bottom part down.
