Detailed description of the invention
One of core of the present utility model is to provide down tube Su Jin mechanism in one, so as to make the locking of down tube
More convenient, promote Consumer's Experience.
Another core of the present utility model is to provide a kind of electric fan with above-mentioned upper down tube Su Jin mechanism.
In order to make those skilled in the art be more fully understood that this utility model scheme, below in conjunction with the accompanying drawings and be embodied as
The utility model is described in further detail for mode.
Please also refer to Fig. 1 and Fig. 2, Fig. 1 is the quick-fried of upper down tube Su Jin mechanism disclosed in this utility model embodiment
Fried schematic diagram, Fig. 2 is the cross-sectional view of upper down tube Su Jin mechanism disclosed in this utility model embodiment.
In upper down tube Su Jin mechanism disclosed in this utility model embodiment, including hoop body, pull bar 4 and rotation hands
Handle 7, concrete, hoop body can fixing with any one in upper pipe or down tube 9 be connected, and is provided with on hoop body for other one
The hoop 1 that pipe penetrates, the two ends (head end and tail end) of hoop 1 have support brace 3 positioned opposite, and pull bar 4 passes support brace 3,
And one end of pull bar 4 is provided with the locating part preventing self abjection support brace 3, and the other end is provided with the first locking termination 6, rotation
Changing hands handle 7 to be located on pull bar 4, and rotary handle 7 can rotate around pull bar 4, rotary handle 7 is positioned at the first locking termination 6 He
Between support brace 3, rotary handle 7 is coordinated with the first locking termination 6 by the second locking termination 8, and the first locking termination 6 and
The cooperation face of the second locking termination 8 is the inclined-plane of α at an acute angle with the axis of pull bar 4.
As shown in Figure 2, hoop body is fixedly connected in pipe or down tube 9, and the first locking termination 6 and the second lock
The cooperation face of not-go-end head 8 is and the inclined-plane of pull bar 4 axis α at an acute angle, when rotary handle 7 rotates around pull bar 4, and the second locking end
8 will promote the first locking termination 6 to move up at the axle of pull bar 4, thus drive pull bar 4 to strain or unclamp hoop 1, and with
Another in upper pipe that hoop 1 coordinates or down tube 9 will which achieves the fast of top tube and down tube 9 by quick locking or unclamp
Speed is locked or unclamps.
It can be seen that upper down tube Su Jin mechanism disclosed in above-described embodiment, only can be fast by rotation rotary handle 7
Speed realizes the locking of upper down tube easily and unclamps, and compared to prior art, on this, the operation of down tube Su Jin mechanism is more convenient,
In hgher efficiency, thus Consumer's Experience is also the most more preferably.
It will be appreciated by persons skilled in the art that the size of sharp angle α can be determined according to actual needs, but,
If the angle too small of α, then coupling mechanism force is the least, may result in and be not sufficiently stable at the link position of down tube, and if the angle of α
Spending big, that coupling mechanism force will be excessive, is unfavorable for the rotation of rotary handle 7, to this end, the sharp angle α in the present embodiment arrives at 30 °
Between 60 °, including endpoints thereof, being more highly preferred to, sharp angle α is 45 °, and this angle can ensure that rotary handle 7 rotates 1/4th
The locking of down tube can be realized, it is ensured that Su Jin mechanism has higher locking efficiency about circle.
In this utility model one embodiment, the lower end of hoop body is specially and a hoop 1 hoop seat 2 being connected, and this hoop seat 2
Can embed down tube 9 internal, hoop seat 2 is fixing with down tube 9 card dress.The mode that hoop seat 2 is fixed with down tube 9 card dress is not limited to one
Kind, such as claw is set on hoop seat 2, down tube 9 relevant position arranges the bayonet socket adaptive with claw, or on hoop seat 2
Resilient key is set, down tube 9 relevant position arranges the card dress that the lock-joint adaptive with resilient key all can realize binding round seat 2 with down tube 9
Coordinate.
It should be appreciated that on the one hand the effect being arranged on the locating part of pull bar 4 one end is pretension support brace 3, the opposing party
Face is to prevent pull bar 4 from coming off from support brace 3, and therefore the form of locating part can have multiple choices, such as elastic bayonet lock, nut
5 etc., it is contemplated that the convenience of installation, this utility model embodiment preferably use nut 5 screw as locating part, nut 5
End at pull bar 4.Nut 5 will cause after excessively screwing in pull bar 4 binding round 1 tension, thus be inconvenient to go up between down tube relative
The regulation of position, excessively screws in pull bar 4, ensures nut 5 pretension pull bar 4 simultaneously, also drawing in the present embodiment in order to avoid nut 5
Spacing convex shoulder 10 it is provided with, as shown in Figure 2 on bar 4.
When rotary handle 7 rotates, the first locking end on pull bar 4 will be given in the second locking termination 8 on rotary handle 7
6 apply bigger active force, in order to reach locking effect, need to avoid pull bar 4 to follow rotary handle 7 and rotate, to this end, this reality
Execute example is offered on support brace 3 for the through hole that passes for pull bar 4 be anti-rotating hole, the shape of the cross section of pull bar 4 and anti-rotation
The shape in hole is consistent, thus is prevented effectively from pull bar and rotates.
It is true that as long as non-circular Kong Junke plays anti-rotation effect, it is contemplated that the convenience of processing, this utility model
Anti-rotating hole in embodiment recommends shape changeable hole or D type hole, as shown in Figures 1 and 2.
The invention also discloses a kind of electric fan, such as stand fan, this electric fan include upper pipe that suit connects and
The disclosed tight machine of upper down tube speed it is additionally provided with in above-mentioned any one embodiment at down tube, and the binding site of top tube and down tube
Structure.
Owing to have employed above-mentioned upper down tube Su Jin mechanism, thus this electric fan to have above-mentioned upper down tube Su Jin mechanism concurrently corresponding
Technological merit, no longer repeats this herein.
Above electric fan provided by the utility model and upper down tube Su Jin mechanism are described in detail.Herein should
Being set forth principle of the present utility model and embodiment by specific case, the explanation of above example is only intended to side
Assistant solves method of the present utility model and core concept thereof.It should be pointed out that, for those skilled in the art,
On the premise of without departing from this utility model principle, it is also possible to this utility model is carried out some improvement and modification, these improve
Also fall in this utility model scope of the claims with modification.
