Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that the present invention is protected
The limitation of scope.
The present invention proposes a kind of scalable icing detection rod, and with reference first to Fig. 1, it includes the icing detection of V belt translation tooth
Rod body 1, sleeve pipe 2, band spring gear 3, the electric connector 4 engaged with the gear of detector bar body 1, the detector bar sheet
Body, such as the Part I for including carrying indicator lamp successively from left to right in Fig. 1, the Part II being wrapped in described sleeve pipe 2, with
And the Part III with the sliding contact of electric connector 4, through hole 11, icing detection rod are provided with the side wall of described sleeve pipe 2
The left end of body 1 can stretch out sleeve pipe 2, to realize the purpose of the spy icing of icing detection rod.
In the present embodiment, the Part II of the detector bar body 1 includes two blind holes, with reference to figure 2 and Fig. 3, pacifies respectively
Equipped with the first alignment pin 5 and the second alignment pin 8, first alignment pin 5 connects the first electromagnet 7, institute by the first spring 6
State the second alignment pin 8 and second electromagnet 10 is connected by second spring 9, the alignment pin 8 of the first alignment pin 5 and second can be
In blind hole corresponding to being fallen under spring-force driven dual and corresponding to protrusion outside blind hole；
First alignment pin 5, the first electromagnet 7, the second alignment pin 8, the second electromagnet 10 and the indicator lamp are equal
Electric connector 4 described in Electricity Federation, the icing detection rod body 1 have：
State is pressed into, as shown in Fig. 2 under the state that is pressed into, the electric connector 4 powers off, and first alignment pin is in bullet
The blind hole of the lower protrusion detector bar body 1 of spring force effect, and stretch into the through hole 11 of described sleeve pipe, second alignment pin is in spring
Fallen under power effect in the blind hole of detector bar body 1, the band spring gear 3 is in energy accumulating state；
By doing well, as shown in figure 3, under by doing well, or as under ejection state, the electric connector 4 is powered,
Under electromagnetic force, compression spring is simultaneously fallen into the corresponding blind hole of the detector bar body 1 first alignment pin, and second is fixed
Position pin is under electromagnetic force, extension spring and the corresponding blind hole for protruding detector bar body 1, and then stretches into the through hole of described sleeve pipe
In 11, the band spring gear 3 is in free state.
It is understood that applying pressure when being pressed into be artificial, the now band accumulation of energy of spring gear 3, electric connector 4 is not to two
Individual electromagnet power supply, the first spring 6 has the elastic potential energy of the inner wall compressive of sleeve 2, and is moved to through hole in the first alignment pin
When at 11, above-mentioned elastic potential energy is released, and the end of the first alignment pin is stretched into the through hole 11, limits detector bar body 1
The motion relative to sleeve pipe 2；Second spring 9 is in free state, and under the free state, the second alignment pin 8 income freezes
In corresponding blind hole on detector bar body, the motion to icing detection rod body 1 will not produce restriction effect.Ejection state acts on
Principle is similar, repeats no more.
In the present embodiment, described sleeve pipe 2 is axially disposed bar-shaped trough, and the icing detection rod body 1 is being pressed into state
During with by being changed between doing well, the alignment pin 8 of the first alignment pin 5 or second slides in the bar-shaped trough.It is appreciated that
, bar-shaped trough is provided on the inwall of sleeve pipe, to provide the guide effect of the first alignment pin and the second alignment pin, is being had
In the case of having bar-shaped trough, under corresponding spring or electromagnetic force, its end is somewhat for the first alignment pin and the second alignment pin
It can protrude corresponding to icing detection rod body outside blind hole, even if i.e. the first alignment pin and the second alignment pin are from the through hole 11
When place is withdrawn, in the corresponding blind hole that will not also fall completely within icing detection rod body 1, but expose a part of and above-mentioned bar-shaped trough
Coordinate and be oriented to, to prevent icing detection rod body 1 from being rotated relative to sleeve pipe 2 position-limiting action of two alignment pins is lost.
In the present embodiment, for the above-mentioned function of protrusion, that is, rotation of the icing detection rod body 1 relative to sleeve pipe 2 is prevented, is only protected
Stay moving axially relative, to be made up of the first alignment pin 5, the first spring 6 and the first electromagnet 7 the first pin assembly edge knot
Circumferentially having for ice detector bar body 1 is multiple, and equally, bar-shaped trough is also disposed with a plurality of.It is understood that by the second positioning
Pin 8, the electromagnet 10 of second spring 9 and second form the second pin assembly along icing detection rod body 1 circumferentially
Have multiple.
Corresponding, in the present embodiment, the through hole 11 is multiple along circumferentially having for sleeve pipe 2, to receive above-mentioned multiple
One alignment pin or multiple second alignment pins.
In alternate embodiment, if icing detection rod body 1 needs to rotate relative to sleeve pipe 2, above-mentioned multiple circumferences point
The through hole of cloth can connect to form annular groove, it is to be understood that now no longer need or be not in guiding function
Bar-shaped trough.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
The present invention is described in detail with reference to the foregoing embodiments for pipe, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from the essence of various embodiments of the present invention technical scheme
God and scope.
