For routine, the upgradeable fan of head, it generally all has telescopic tubular structure, and namely the head of fan is fixed on the top of telescoping inner, and telescoping inner is arranged in fan footstool, and can move up and down in fan footstool.The utility model makes concrete improvement based on to the elevating control mode of telescoping inner in fan footstool, and the embodiment of concrete scheme is as follows:
Embodiment one,
A kind of lowering or hoisting gear of fan, comprise motor 1, worm screw 21 and worm gear 31, wherein, as shown in Figure 1, motor 1 is arranged in the chassis of fan bottom, it is inner that worm screw 21 is vertically arranged on outer tube 7, its bottom is fixedly connected with the main shaft of motor 1, can along with its main shaft rotates under the rotation of motor 1, worm gear 31 is fixed on the telescoping inner 6 of fan, and worm gear 31 engages with worm screw 21, limited location snap ring 5 is provided with on the top of outer tube 7, for preventing the horizontal jitter of telescoping inner 6, in fan, control system is set, for controlling rotating and reverse of motor 1, according to the lifting rotating and reverse control telescoping inner 6 of motor 1, such as, when motor 1 rotates forward, motor 1 main shaft drives worm screw 21 to rotate, meanwhile, the worm gear 31 engaged with worm screw 21 is under the rotation of worm screw 21, move up and down along worm screw 21 entire body, because worm gear 31 is fixed on telescoping inner 6, therefore, in the process that worm gear 31 moves up and down along worm screw 21 entire body, telescoping inner 6 is also just along with worm gear 31 moves up and down, and the head of fan is fixed on telescoping inner 6 top, therefore, fan head also just can realize upgrade function along with moving up and down of worm gear 31.
The first embodiment of the lowering or hoisting gear of a kind of fan of the utility model is applied in situation in fan as shown in Figure 1, the schematic diagram of the head lifting fan namely in the utility model, in the drawings, worm gear 31 has risen to the phase diagram at worm screw 21 top, and now the head of fan is in extreme higher position.As shown in the figure, in order to better fix worm screw 21, that the outer tube 7 of fan can be done is comparatively thick, present one excessively step-like, from outer tube 7 outside, step-like excessive top is as fan footstool 4, when installing worm screw 21, worm screw 21 is arranged on the step-like excessive inside of outer tube 7, namely the partial interior that its body given prominence to by outer tube 7 is in, its top is against on outer tube 7, for this, the position that can contact with worm screw 21 at outer tube 7 arranges a concave point (not shown), worm screw 21 top is arranged in this concave point, ensure while worm screw 21 is fixed, can also rotate under the drive of motor 1 main shaft, certainly, also can arrange in the position of the concave point of outer tube 7 bearing or other can also make its existing apparatus rotated or structure by fixing for worm screw 21 simultaneously, accordingly, when installing motor 1, also to ensure that its main shaft is positioned at below worm screw 21, make the two be fixedly connected with, when motor 1 rotates, its rotating shaft drives worm screw 21 to rotate.
In Fig. 1, when hotwire 1, it is made to start to rotate in the mode moved downward by worm gear 31, the flexible long tube 6 of fan moves downward jointly along with worm gear 31, make fan head start to decline, until worm gear 31 moves to the bottom of worm screw 21, the head of fan is also down to least significant end, reach state as shown in Figure 2, complete the decline adjustment process of fan; Rotate backward motor 1, the uphill process of fan head can be completed.
Embodiment two,
A kind of lowering or hoisting gear of fan, as shown in Figure 3, comprise motor 1, screw mandrel 22 and nut 32, wherein, motor 1 is fixed in the chassis (not indicating in figure) of fan, further, can a motor bracket 8 be set in fan chassis, motor 1 is fixed in motor bracket 8, the main shaft of motor 1 towards vertical direction, simultaneously, the main shaft of screw mandrel 22 one end and motor 1 is fixed together, guarantee that screw mandrel 22 is positioned at vertical direction, when motor 1 rotates, its main shaft can drive screw mandrel 22 to rotate at the main shaft of vertical direction along with motor 1, nut 32 is screwed on screw mandrel 22 by its tapped hole, simultaneously, nut 22 entirety is fixed on nut and fixes on snap ring 9, and nut is fixed snap ring 9 and is fixed on telescoping inner 6 simultaneously, like this, when unlatching motor 1, the entry into service of motor 1 main shaft, thus drive screw mandrel 22 to rotate, in the rotation process of screw mandrel 22, be enclosed within the rotation of the nut 32 above screw mandrel 22 along with screw mandrel along the rising of screw mandrel entire body (or decline), nut 32 drives nut to fix snap ring 9 successively, telescoping inner 6 rises (or decline), thus make the control to fan head, control motor 1 counterrotating, nut 32 can be made to decline (or rising), then nut is driven to fix snap ring 9 and telescoping inner 6 declines (or rise), fan head is comprehensively made to realize the function rising or decline.
As shown in Figure 3, on the top of fan footstool 4, its position contacted with telescoping inner 6, be provided with limited location snap ring 5, for limiting the movement of the substantially horizontal of telescoping inner 6, prevent it from the uphill process along with nut 32, occurring horizontal jitter, guarantee that telescoping inner 6 can stretch out stably or shrink from fan footstool 4.
Fig. 4 is the schematic diagram that the head of fan in the utility model the second embodiment is in extreme higher position, nut 32 rises to its top along screw mandrel 22, fan head is in state during highest point, if now control motor 1 to rotate backward, make it drive screw mandrel 22 to rotate, this back nut 32 just can decline along screw mandrel 22, thus drive nut fixes snap ring 9 and telescoping inner 6 declines jointly, finally make the head of fan decline, be in the state shown in Fig. 3.
In this embodiment, the lowering or hoisting gear of above-mentioned fan applied by the liftable fan of head, and its structural representation can refer to shown in Fig. 3 and Fig. 4, no longer repeats at this.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those skilled in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
