A kind of travel switch of plastic draining board electromagnet cutter
Technical field
Used present invention is mainly used for plastic draining board of being constructed in Soft foundation treatment engineering.
Background technology
The patent of invention " plastic draining board electromagnet cutter " applied, application number:2017106872977 need one
Travel switch is planted, when leading proposition mud top surface on boots, the power supply of plastic draining board electromagnet cutter is connected, by plastic row
Water plate is cut off at mud top surface.
The content of the invention
The present invention is exactly this travel switch, and it mainly includes shell fragment(1), push rod(2), anti-water pocket(3), point driving switch
(5), slide bar(6), spring(7), baffle plate(8);Shell fragment(1)By short side(10), long side(11)Composition, short side(10)With leading boots(12)
Short side lateral surface fix, long side(11)With leading boots(12)Short side lateral surface into a downward oblique angle, push rod(2)Right-hand member
With shell fragment(1)Long side(11)Bottom fix, push rod(2)Left end through leading boots(12)Short side hole, push rod(2)Can be with
Slided along its hole, push rod(2)Left end be fixed with bulb(9), point driving switch(5)Shell(4)With leading boots(12)Inwall consolidate
It is fixed, point driving switch(5)Slide bar is installed(6), slide bar(6)Right-hand member be fixed with baffle plate(8), spring(7)Through slide bar(6), bullet
Spring(7)One end and baffle plate(8)It is fixed, spring(7)The other end and point driving switch(5)Shell(4)It is fixed, slide bar(6)Can
With in point driving switch(5)Inside horizontally slip, slide bar(6)Left end can drive point driving switch(5)Wire contact connect and disconnected
Switch power supply, anti-water pocket(3)Opening surface and lead boots(12)It is fixed, anti-water pocket(3)It can prevent seawater or mud from invading stroke
In switch;Its operation principle is:Leading boots(12)Drop to mud bottom and above carry to mud top surface during this, bullet
Piece(1)Long side(11)Under the extruding of mud, long side(11)In downward case of bending, push rod(2)Bulb(9)Head on
Baffle plate(8), spring(7)In compressive state, point driving switch(5)It is off, electromagnet cutter are in off-position,
When leading boots(12)During upper proposition mud top surface, shell fragment(1)Long side(11)Lose the squeezing action of mud, shell fragment(1)'s
Long side(11)Resilience resets, and drives push rod(2)Turn right an angle, while spring(7)Resilience extends, band moving slide-bar
(6)And baffle plate(8)Move right, slide bar(6)Left end drive point driving switch(5)Wire contact switch on power, to electromagnet
Cutter are powered and cut off plastic draining board, then point driving switch(5)Power-off, electromagnet cutter reset;Need explanation:Leading
Boots(12)Referred in continuation during dropping to mud top surface again, although shell fragment(1)Long side(11)There is no mud
Squeezing action, shell fragment(1)Long side(11)In open configuration, but in this course, point driving switch(5)In disconnection shape
State, electromagnet cutter are in off-position.
