Abstract
The utility model relates to the motor fan technology, in particular to an improvement of the stator screw in the motor fan with gentle breeze. The utility model is composed of a hollow screw, the end nozzles of which are embedded with shaft housings. The utility model is characterized in that a concave convex cooperating structure is arranged between the shaft housing and the screw nozzle joint. The utility model ensures that the shaft housing do not rotate with the rotating shaft and serves as the bearing all along, thus prolonging the service life of the product.
Description
Technical field:
The utility model relates to the improvement of screw stator in the electric fan technology, particularly Soft wind electric fan.
Background technique:
Existing Soft wind electric fan adopts synchronous machine, and coil is as stator, be enclosed within the outer magnetic sheet of coil in company with shell as rotor, and drive the fan blade rotation.Outer casing bottom is fixed in the hollow type screw stator that a rotating shaft penetrates hub of a spool.Usually to rotate flexibly in order making, to embed the Nylon axle sleeve at screw stator center hole two ends, play the bearing effect of rotating shaft.Because the nylon sleeve outer wall is smooth, after heating is turned round in rotating shaft for a long time, the nylon sleeve endoporus that engages is sticked together, thereby make nylon sleeve with the rotation of rotating shaft relative stator screw rod, lost the effect of bearing, cause the electric fan premature damage.
Summary of the invention:
The Soft wind electric fan screw stator that order of the present utility model provides a kind of nylon sleeve not rotate with rotating shaft.
The utility model is made of the hollow type screw rod of two ends mouth of pipe setting-in axle sleeve, and it is characterized in that has concavo-convex cooperating structure between axle sleeve and the screw rod hollow mouth of pipe junction point.The both ends of the surface of screw rod have groove or pit, and the relative capping of axle sleeve is shaped on corresponding fin or projection, both concavo-convex cooperations.
Above-mentioned concavo-convex fit form has various ways, and concavo-convex relative position is also interchangeable, belongs to the general knowledge technology.
The utility model is owing to become concavo-convex matching relationship with axle sleeve with screw design, make axle sleeve and the screw rod can't relative movement, thereby guaranteed that axle sleeve plays the bearing effect all the time, prolonged product working life.
Description of drawings:
Fig. 1 is the example structure schematic representation.
Fig. 2 is the axle sleeve plan view.
Fig. 3 is Fig. 2 plan view.
Embodiment:
With reference to Fig. 1, hollow pipe 1-1 is arranged in the screw stator 1, its both ends of the surface respectively have along diametric groove 1-2, and two ends pipeline 1-1 oral area respectively embeds Nylon axle sleeve 2, and axle sleeve 2 relative cappings are shaped on radially fin 2-1, and cooperate with groove 1-2 is concavo-convex.Axle sleeve 2 is shaped on axis hole 2-2, is used for that rotating shaft is bottom-up to be run through, as Fig. 2, shown in Figure 3.
Claims (2)
1, a kind of Soft wind electric fan screw stator is made of the hollow type screw rod of two ends mouth of pipe setting-in axle sleeve, it is characterized in that between axle sleeve (2) and screw rod (1) the hollow mouth of pipe junction point concavo-convex cooperating structure being arranged.
2, screw stator according to claim 1 is characterized in that the both ends of the surface of screw rod (1) have groove (1-2) or pit, and axle sleeve (2) capping relatively is shaped on corresponding fin (2-1) or projection, both concavo-convex cooperations.
