Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
Body embodiment purpose, it is not intended that in limitation the present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
Referring to Fig. 1, the embodiment of the present invention provides a kind of power switch 100, including rotary body 10, switch block 20 and
Two wiring bodies 30.In actual use, two wiring bodies 30 are respectively intended to external cord 200, and switch block 20 can control two
Whether a wiring body 30 is electrically connected, and then controls whether two electric wires 200 being connected respectively with two wiring bodies 30 are electrically connected
It is logical.
Specifically, referring to Figure 2 together, rotary body 10 can be driven is rotated centered on own rotation axis 11, this reality
It applies in example, rotary shaft 11 is the central axis of rotary body 10.Switch block 20 is contained in rotary body 10 and deviates rotary shaft 11, opens
Closing component 20 can rotate together with rotary body 10, i.e. during switch block 20 is with rotary shaft 11 under the drive of rotary body 10
Heart rotation.
Referring to Fig. 3, switch block 20 includes the first elastic component 21, the sliding block 22 set gradually along the radial direction of rotary body 10
And second elastic component 23, wherein the first elastic component 21 is located at sliding block 22 close to the side of rotary shaft 11, and the second elastic component 23 is located at
Side of the sliding block 22 far from rotary shaft 11.
Specifically, wherein one end of the first elastic component 21 connects with sliding block 22, and the other end is connected with a wiring body 30.
Wherein one end of second elastic component 23 connects with sliding block 22, and the other end extends towards the direction for remaining next wiring body 30, and with
This remains the separable contact of next wiring body 30.
In the present embodiment, the first elastic component 21 and the second elastic component 23 are spring.Sliding block 22 includes sliding part 221, the
One insertion section 222 and the second insertion section 223, the first insertion section 222 and the second insertion section 223 are located at the sliding part 221
Both ends.First insertion section 222 is inserted into the helical spring hole of the first elastic component 21, the second elasticity of the second insertion section 223 insertion
In the helical spring hole of part 23.
The working principle of power switch 100 provided by the invention is: rotary body 10 is driven centered on rotary shaft 11
When rotation, the centrifugal force radial along rotary body 10 by one of sliding block 22, and sliding block 22 is only limited close to one end of rotary shaft 11
In the first elastic component 21, the first elastic component 21 has stretchable function, therefore, when the rotation speed of rotary body 10 reaches one in advance
If value makes centrifugal force be in contact with it the maximum static friction force between face equal to sliding block 22, continuing increase rotation speed later will
Sliding block 22 is set to stretch the first elastic component 21 and radially sliding along rotary body 10.Specifically, sliding block 22 drives the second elastic component 23
Next movement of wiring body 30 is remained towards mentioned-above, so that the second elastic component 23 remains next 30 phase of wiring body with this
Contact, realizes the electric connection of two wiring bodies 30.
It is appreciated that sliding block 22 loses centrifugal force and in the elasticity of the first elastic component 21 when rotary body 10 stops rotating
Restoring force acts on lower slider, so that the second elastic component 23 remains next connect far from mentioned-above as sliding block 22 moves together
Wire body 30, at this point, two wiring bodies 30 are in non-electrical connection status.In addition, it is necessary to explanation, sliding block 22 is along rotary body 10
Radial movement is not influenced by 10 direction of rotation of rotary body, and therefore, rotary body 10 can bidirectional rotation.
Referring to Figure 4 together, switch block 20 further includes insulation sleeve 24, insulation sleeve 24 along rotary body 10 be arranged radially and
Close to one end of rotary shaft 11 offers the first container 241, the other end offers the second container 242.Two wiring bodies 30
It is respectively accommodated in the first container 241 and the second container 242.
Further, what insulation sleeve 24 was also provided with perforation the first container 241 and the second container 242 is connected to chamber 243.

Cooperation.
Specifically, connection chamber 243 includes being sequentially connected the first logical cavity 2431, the second cavity 2432 and third cavity
2433, wherein the first cavity 2431 and the first container 241 are adjacent, and third cavity 2433 is adjacent with the second container 242
It connects.First elastic component 21 is partially housed in the first cavity 2431, and the second elastic component 23 is partially housed in third cavity 2433, sliding block
22 sliding part 221 is contained in the second cavity 2432.
In the present embodiment, the cross sectional shape and size of the first cavity 2431 correspond to the first elastic component 21, to the first bullet
Property part 21 plays certain position-limiting action.The cross sectional shape and size of third cavity 2433 correspond to the second elastic component 23, with right
Second elastic component 23 plays certain position-limiting action.
In the present embodiment, insulation sleeve 24 includes the insulating cover 244 and insulating base 245 contacted.Specifically, the first receiving
Slot 241 is opened in the one end of insulating cover 244 far from insulating base 245, and the second container 242 is opened in insulating base 245 far from insulation
One end of lid 244.First cavity 2431 is opened on insulating cover 244, and the second cavity 2432 and third cavity 2433 are opened in absolutely
On edge seat 245.
It should be noted that the insulation sleeve 24 formed in such a way that insulating cover 244 is contacted with insulating base 245 is conducive to
The filling of sliding block 22 assembles, but not limited to this.
Further, the present invention also provides a kind of measuring device (not shown), which includes any of the above-described implementation
