Abstract
A fan stand column lifting device comprises an outer adapter assembly, an inter stand column pipe and an outer stand column pipe. The device is characterized by further comprising an elastic clamping device, the elastic clamping device is arranged on the inner stand column pipe in a sleeved mode and is fixed after the inner stand column pipe is inserted into the outer stand column pipe, reinforcing ribs are arranged on the inner wall of the outer stand column pipe, and the degree of tightness of the elastic clamping device is controlled through the rotation of the outer adapter assembly, matched threads are arranged at the upper end of the outer wall of the outer stand column pipe and on the inner wall of the outer adapter assembly respectively, the outer adapter assembly and the outer stand column pipe are fixed in a screwing mode, and multiple deformation gaps parallel to the inner stand column pipe are formed in the surface of the elastic clamping device. Due to the fact that the elastic clamping device is pressed to clamp the inner stand column pipe by rotating the outer adapter assembly and the elastic clamping device is formed by integral stamping with plastic, production is easy. Compared with the prior art, the fan stand column lifting device has the advantages of being simple in structure, low in production cost and convenient to maintain.
Description
Technical field
The utility model relates to a kind of lowering or hoisting gear for fan pillar stand.
Background technique
At present, the lifting regulating mechanism of vertical pole of electric fan has three kinds.The first is to adopt screw thread positioning knob, on external riser, process tapered thread and open clip slot, the mode of its lift adjustment is: unclamp screw thread positioning knob, with the electric fan handle of having handed up to needed height, and then locking screw positioning knob, complete the action of fan upgrading; When column will descend timing, first to unclamp screw thread positioning knob, under the effect of fan gravity, column drops to needed height, and then locking screw positioning knob, completes the action that fan declines.This lift in height mechanism structure is complicated, is difficult for assembling, and while particularly the electric fan of two columns being carried out to lift adjustment, both sides are difficult for being adjusted on sustained height, operating difficulties, spended time.
The second is to adopt limited bolt and lifting button.When column need to raise, as long as fan handle is upwards lifted, limited bolt can automatically exit the groove of giving up the throne under the effect of limit spring, completes column vertical motion; When column will descend timing, with hand, pull out lifting button, limited bolt automatically exits restraining groove under the effect of limit spring, decline along with column, limited bolt is when running into higher level's restraining groove, limited bolt automatically snaps in and is locked in the restraining groove of column under the effect of limit spring, completes column down maneuver.This up-down mode is very convenient when fan raises operation, but during decline fan due to one-handed operation, the elastic force that people will overcome spring is stretchy lifting button, operates more difficult.
The third is to adopt spring and limited bolt.When needs raise, as long as fan handle is upwards lifted, limited bolt can automatically exit restraining groove under the effect of limit spring, completes column vertical motion; When column will descend timing, with the hands to pressing down fan, when pressure is greater than the pressure of limit spring, limited bolt exits restraining groove automatically, decline along with column, limited bolt is when running into upper level restraining groove, and limited bolt automatically snaps in and is locked in the restraining groove of column under the effect of limit spring, completes column down maneuver.This lift in height mechanism is simple, easily assembling, rising fan is very easily, but decline fan be need to be larger strength.
Model utility content
The purpose of this utility model is to provide a kind of elevation and subsidence regulating device of simple in structure, the vertical pole of electric fan of producing easy, easy to use, rapid operation.
The utility model is realized with the following methods: a kind of lowering or hoisting gear of fan pillar stand, comprise socket assembly, inner column pipe and outer column pipe, characterized by further comprising elastic clamp device, described elastic clamp device is enclosed within on inner column pipe, along with inner column pipe inserts in outer column pipe fixing, column tube inwall is provided with on stiffening rib outside, by the rotation of socket assembly, controls elastic clamp device degree of tightness.
In the lowering or hoisting gear of above-mentioned fan pillar stand, on described outer column pipe outer wall upper end and socket assembly inwall, be respectively provided with the screw thread matching, described socket assembly and outer column pipe are by being tightened.
In the lowering or hoisting gear of above-mentioned fan pillar stand, described elastic clamp device surface is provided with some the deformation gaps that are parallel to inner column pipe.
In the lowering or hoisting gear of above-mentioned fan pillar stand, described stiffening rib upper end slopes inwardly and forms the spacing inclined-plane matching with elastic clamp device bottom surface.
In the lowering or hoisting gear of above-mentioned fan pillar stand, described elastic clamp device is that plastics integrated injection molding forms.
The beneficial effects of the utility model are: the fan pillar stand that uses the utility model structure, by rotation socket assembly compressing elastic clamp device, clamp inner column pipe, and elastic clamp device plastics integrated punching forms, produce easily, compared with prior art, have simple in structurely, cost of production is low, advantage easy to maintenance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of the lowering or hoisting gear of the utility model fan pillar stand.
Fig. 2 is the enlarged view of Fig. 1.
Fig. 3 is that the utility model screws view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
A kind of lowering or hoisting gear of fan pillar stand, comprise socket assembly 1, inner column pipe 2 and outer column pipe 3, characterized by further comprising elastic clamp device 4, described elastic clamp device 4 is enclosed within on inner column pipe 2, along with inner column pipe 2 inserts in outer column pipe 3 fixing, column tube 3 inwalls are provided with stiffening rib 5 outside, by socket assembly 1 rotary squeezing, control elastic clamp device 4 degrees of tightness.
In the lowering or hoisting gear of above-mentioned fan pillar stand, on described outer column pipe 3 outer wall upper ends and socket assembly 1 inwall, be respectively provided with the screw thread 6 matching, described socket assembly 1 and outer column pipe 3 are by being tightened.
