Abstract
The utility model relates to a lift device for a fan upright column, in which the upright column is made into a supporting column and a bushing which are mutually connected in bell socket. The design is characterized in that a spiral spring is arranged between the supporting column and the bushing, one end of the spiral spring is fixed on the inner wall of the bushing, and the other free end is curled in the opening on the lower end of the supporting column, the spiral spring can curl or stretch with the elevating of the supporting column, maintaining a stable upward elasticity which counteracts the weight of the fan, and making the elevating easily. Because the function of friction force, the fan can stay at any position without external force, so the fastening screw can be saved.
Description
The utility model relates to a kind of lowering or hoisting gear of electric fan column.
Existing tableland formula and pedestal fan generally are to fix a root post on base, and the fan head is installed in the top of column.Use height in order to regulate, be provided with lowering or hoisting gear on the column mostly, for example column is made mutual socket two sections or three sections, for sake of convenience, can be called pillar with thinner one section, the thicker sleeve pipe that is called, pillar is inserted in the sleeve pipe, by insertion portion how much change the column height, locate with fastening screw again.Though this device can satisfy the needs of regulating height, each lifting all will be unclamped fastening screw earlier, tightening the screw again after the lifting, and it is very inconvenient to use.During each lifting, also the weight highland because of the electric fan main frame is in the column top, makes lifting very painstaking.
In order to overcome the deficiencies in the prior art, task of the present utility model provides a kind of new electric fan column lifting device, and it should be able to realize the lifting of electric fan column with very easy mode, realizes one drawing, one by promptly finishing lifting, do not need to go again to unclamp, fix, deduct original troublesome operation.New structure also should make operation very light laborsaving.
The scheme that realizes the foregoing invention purpose is as follows: same as the prior art, column is made the pillar and the sleeve pipe of mutual socket, and pillar inserts in the sleeve pipe.The design's feature is: a wind spring is installed between pillar and sleeve pipe, and an end of wind spring is fixed on the internal surface of sleeve pipe, and its free end is crispaturaed in the pillar lower ending opening, pillar lower ending opening place, install a lower cover additional, covered an opening down, it is flexible that wind spring passes this opening.This wind spring can be crispaturaed along with the lifting of pillar or stretch, and remains a more constant upwards elastic force, and this elastic force and fan pillar are cancelled each other with the weight on top, make the lifting of fan free and relaxed.Because the effect of friction is not having external force to do the time spent, fan can be stablized and rests on the arbitrary position, can not go up bullet or downslide, so can save fastening screw, uses very convenient.On slide fan, the sleeve portion of column can be made an integral body with base, and structure is compact more.
The utility model has overcome the deficiencies in the prior art, makes the lifting of electric fan pillar freely, and is simple, convenient, also very laborsaving simultaneously.
Now be described further with embodiment in conjunction with the accompanying drawings.
Fig. 1 is the column lifting device structural representation.
Embodiment 1, the slide fan column lifting device, and with reference to Fig. 1: the electric fan column is inserted in the sleeve pipe 2 by pillar 1 to be formed, and sleeve pipe 2 is made an integral body with base 5.One end of wind spring 3 is fixed on the top of internal surface of sleeve pipe, and its free end is crispaturaed in the opening of pillar lower end.In order to obtain maximum lifting distance, the immovable point of wind spring should be tried one's best near the sleeve pipe upper edge.The length of wind spring should be inserted the extreme length of sleeve pipe greater than pillar.Pillar lower ending opening place installs a lower cover additional, has covered an opening down, and it is flexible that wind spring passes this opening.The effect of lower cover be in wind spring is packed the pillar mouth into after, prevent that wind spring from coming off.Wind spring is crispaturaed with the oscilaltion of fan height or is stretched, and remains a more constant upwards elastic force, cancels each other with the weight on top, makes the lifting of fan free and relaxed.Do not having external force to do the time spent, fan is stabilized on the arbitrary position by the effect of friction.
Claims (3)
1, a kind of electric fan column lifting device, column is made the pillar and the sleeve pipe of mutual socket, pillar inserts in the sleeve pipe, it is characterized in that: a wind spring is installed between pillar and sleeve pipe, and an end of wind spring is fixed on the internal surface of sleeve pipe, and its free end is crispaturaed in the pillar lower ending opening, pillar lower ending opening place, install a lower cover additional, covered an opening down, it is flexible that wind spring passes this opening.
2, according to the described electric fan column lifting device of claim 1, it is characterized in that: sleeve portion and base are made an integral body.
3, according to claim 1 or 2 described electric fan column lifting devices, it is characterized in that: the immovable point of wind spring is near the sleeve pipe upper edge, and the length of wind spring is inserted the extreme length of sleeve pipe greater than pillar.
