Description

The fixed mechanism of ceiling fan flabellum

The utility model relates to fan, more specifically to a kind of fixed mechanism of ceiling fan flabellum.

The present ceiling fan that uses, flabellum relies on screw to be connected with motor.Common installation is, operator take off screw and spring washer from motor, then the screw of flabellum fixed end with after the fixing threaded hole on the motor is aimed at, screw passes the screw of spring washer and flabellum fixed end and the fixing threaded hole on the motor earlier, screw-driving, promptly finish the fixed installation of ceiling fan flabellum at last.Because of flabellum has certain weight, the screw of flabellum fixed end be aimed at the screw on the motor is not to be easy to; Must stand in because of operator that ladder is gone up again or support platform on work, the sphere of activities of both feet is limited, if the time is long, may be soft or neck is aching and limp, again if be not steady on one's legs, just can dangerously take place at any time.In addition, when set screw, tend to from screw, deviate from, drop on the ground because of undue force makes screw.At this moment, need oneself to climb down or make others pick up screw, row is fixing again.Seeming very bothers and inconvenience, and needization are taken the long period.

In view of existing the problems referred to above in the prior art, the purpose of this utility model provides a kind of fixed mechanism of ceiling fan flabellum, makes the steady job of ceiling fan flabellum easy, quick safety again.

The purpose of this utility model is achieved in that by means of in two fixing threaded holes that are preset on the ceiling fan motor and by corresponding to two holes of motor fixed hole setting flabellum being fixed on the screw on the ceiling fan motor on the described ceiling fan flabellum fixed end and being socketed in packing ring on the screw, the ceiling fan flabellum is fixed.On the described flabellum fixed end corresponding to the aperture in two holes of motor fixed hole setting greater than the diameter that is preset in the screw cap portion on the motor and the external diameter of packing ring, there is an abducent recess the same side on the circumference in these two holes, and the size of this recess just can allow described screw rod portion move therein.

Adopt the fixed mechanism of above-mentioned ceiling fan flabellum, only need the fixed hole on the flabellum fixed end of every flabellum is socketed on the screw that motor presets, again the flabellum fixed end is moved to a thruster, make screw enter the recess of flabellum fixed hole, and then one by one screw is got final product.Operator's convenient power-saving ground is fixed on flabellum on the motor, has improved Security again.

Below in conjunction with accompanying drawing a preferred embodiment of the present utility model is specifically described, wherein:

Fig. 1 is a ceiling fan flabellum fixed mechanism schematic representation of the present utility model;

Fig. 2 is thrust device on the utility model motor and the decomposing schematic representation that presets screw; And

Fig. 3 is the screw schematic perspective view of the utility model fastener tapes packing ring.

Every flabellum fixed mechanism of ceiling fan of the present utility model as depicted in figs. 1 and 2 comprises two screws 3 in two fixing threaded holes 2 that are preset on the ceiling fan motor 1.Described here presetting, the meaning are before a whole set of ceiling fan equipment dispatches from the factory, and all screws 3 are screwed to only surplus a few circle screw threads in the fixing threaded hole 2 of motor 1.As shown in Figure 3, be socketed with a packing ring 4 on the screw 3, this packing ring internal diameter is less than screw 3 screw threads diameter partly, and is provided with a plurality of regularly arranged detent projection on the packing ring excircle, is used to improve the screw check ability.

As shown in Figure 1, there are two holes 6 position corresponding to two fixing threaded holes 2 on the motor 1 on the flabellum fixed end 5 of ceiling fan, and the aperture in this hole is greater than the diameter that is preset on the motor 1 the screw 3 cap portions in two screws 2 and the external diameter of packing ring 4; There is an abducent recess the same side on the circumference in this hole, and its end semicircular in shape, the size of recess (or width) just can allow described screw 3 screw part move therein.When the installation flabellum was on motor, as long as screw 3 and packing ring 4 are passed in two holes 6 of flabellum fixed end 5, and promotion flabellum fixed end 5 made screw 3 enter the extension recess in hole 6, just can be placed on flabellum on the fixed position of motor, then, tighten screw, only several circles get final product.

As shown in Figures 1 and 2, a side of position also is provided with a thrust device 7 after flabellum is fixed on the motor.This thrust device 7 comprise one from the motor the fixing circumferential surface of flabellum can enter the thrust spring sheet 9 that groove can stop flabellum to move again to recessed rectangle groove 8 and.Spring sheet 9 one ends are fixed on the motor circumferential surface with Screw 10, and are slope shape to the other end and extend, and extended vertically downward by sloping top, and vertical extent partly are thrust surface again, stop flabellum to be moved further.The vertical end of this spring sheet partly can enter in the rectangular recess 8 when pressurized and be adjacent to a sidewall of groove.If pressure relief, spring sheet relies on self elastic force, rises from groove 8, is in the thrust position.When promoting flabellum fixed end 5 and make screw 3 enter in the recess in hole 6 fully, the vertical end of the spring sheet of being pushed down by flabellum fixed end 59 just can be in the thrust position by ejecting in the rectangular recess 8, and when fan operates, flabellum fixed end 5 is played the thrust effect, make it not and can promote to make screw 3 to move to hole 6 forward by the centrifugal force when rotating, make the running of ceiling fan safer, reliable from recess.

As shown in Figure 1, in order further to guarantee safety, also be provided with two locating studs 11 at flabellum fixed end 5, there are two positioning pin holes 12 position corresponding to 5 two locating studs 11 of flabellum fixed end on the position that flabellum on the motor 1 is fixed.When promotion flabellum fixed end 5 made screw 3 enter into hole 6, flabellum fixed end bottom surface was pushed down thrust spring sheet 9 and along the spring sheet slope spring sheet 9 is entered in the groove 8.In case screw rod enters in the recess in hole 6, spring sheet 9 is not subjected to fixed end 5 compressings, promptly ejects from groove 8, is in the thrust position.At this moment, the locating stud 11 on the flabellum fixed end 5 also embeds in the positioning pin hole 12 of relevant position on the motor 1 simultaneously, and flabellum is stabilized on the motor.On the other hand, also withstood by thrust spring sheet 9.At last, tighten screw, finish the flabellum steady job.

Above-described is the whole fixing operation process of the fixed mechanism and the flabellum of a slice flabellum.Fixed mechanism and operating process for second and third sheet flabellum are identical with the above.

In sum, the utlity model has simple in structure, easy for installation, processing ease, safety, effect is good The advantage such as good because having saved manpower and time, makes it to have economic benefit.
