Abstract
The utility model relates to a device for automatically preventing bush burning of a gasoline engine. In a hollow cavity which is composed of a housing (7) and an insulated blanking adapter (20), a power switch spring (21), a movable ejector rod (14), an electromagnetic lid (12) and a movable ferrite core (1) are arranged from top to bottom; a switch sheet copper (15) which is in insulated connection with the movable ejector rod is arranged on the movable ejector rod, and a pressure spring (11) wound on the movable ejector rod (14) is arranged in a centre hole of the electromagnetic lid; an electromagnetic coil (10) is wound outside the movable ferrite core (1); an oil cylinder (5) and a piston (4) are arranged below the housing (7); a lighting coil wiring terminal (19) and an ignition switch wiring terminal (22) pass through the insulated blanking adapter (20) and are fixed on the insulated blanking adapter (20). When lubricating oil pressure is below a defined lower limit value, the ignition circuit of the device for automatically preventing bush burning can realize automatic power-off, and the gasoline engine immediately stops working to prevent bush burning. The utility model has the advantages of simple structure and reliable working.
Description
Technical field
The utility model belongs to petrol engine and prevents tile kilning device field automatically.
Background technique
On the petrol engine unit that does not prevent the tile kilning device automatically, the operator of machinery must pay close attention to the demonstration situation of bayonet gauge constantly, not only divert one's attention to divert attention, and accidents happened easily.Though some have also occurred at present the technology that prevents the tile kilning function is automatically arranged, some device structure more complicated, some work is reliable inadequately, is unfavorable for promoting.
Summary of the invention
The utility model petrol engine prevents that automatically technical problem that the tile kilning device will solve from providing a kind of simple in structure, reliable operation and the not high petrol engine of price prevents the tile kilning device automatically.
The utility model solves the problems of the technologies described above with following technological scheme: in the cavity of being made up of shell 7 and insulation plug 20, power switch spring 21, movable push rod 14, electromagnetism lid 12, movable core 1 are installed from top to down, the switch copper sheet 15 that has insulation with it to connect on the movable push rod, stage clip 11 around movable push rod 14 is arranged in the electromagnetism lid center hole, and movable core 1 is around with electromagnetic coil 10; Oil cylinder 5 and piston 4 are arranged below shell 7; Ignition terminals 19 and ignition switch wiring terminal 22 pass and are fixed on the insulation plug 20.
Petrol engine of the present utility model prevents the tile kilning device automatically, and when in-oil cylinder oil pressure was lower than the regulation lower limit, ignition circuit can be realized outage automatically, and petrol engine quits work immediately, has prevented tile kilning., reliable operation simple in structure because of it, fabricating cost are cheap, very are beneficial to popularization.
Description of drawings
Fig. 1 is the structural representation that petrol engine of the present utility model prevents the tile kilning device automatically.
Circuit diagram when Fig. 2 is to use petrol engine of the present utility model to prevent the tile kilning device automatically.
Embodiment
In the cavity of forming by shell 7 and insulation plug 20, power switch spring 21, movable push rod 14, electromagnetism lid 12, movable core 1 are installed from top to down; There is an insulation laminate 16 the movable push rod upper end that is positioned at electromagnetism lid center by adjustment nut 13, and insulation laminate outer rim is fixed with switch copper sheet 15, and stage clip 11 is arranged on every side at movable push rod bottom; Outside the movable core 1 copper sleeve 8, coil covering 9 and electromagnetic coil 10 are arranged, electromagnetic coil two line ends connect solenoid feed terminal both positive and negative polarity 18 and 23 respectively; Ignition terminals 19, ignition switch wiring terminal 22 are fixedlyed connected with insulation plug 20.Screw 17 is connected insulation plug 20 and electromagnetism lid 12 with 24.Oil cylinder 5 and piston 4 are arranged below shell 7.On the insulation plug port 25 is arranged.Screw 6 is the set screws that prevent tile kilning device complete machine.
When opening petrolic ignition switch 26 with key to some A, power connection ignition switch wiring terminal 22, motor 28 startings when key continues to push a some B, electromagnetic coil 10 has simultaneously, the magnetic force that coil produces pulls to the top with movable core 1, movable core promotion activity push rod 14 and switch copper sheet 15 are up, and switch copper sheet 15 is connected ignition terminals 19 and ignition switch wiring terminal 22, gasoline engine ignition system 27 proper functioning.Motor and electromagnetic coil dead electricity when key is returned to a some A, but because the oil pump of motor presses the machine oil import 3 in screw thread filler opening 2 to enter in the oil cylinder 5 in the machine oil of normal pressure in starting, to oil cylinder top, ignition terminals 19 and ignition switch wiring terminal 22 continue to connect with piston 4 tops.In case lubrication pressure is lower than the regulation lower limit in the oil cylinder, stage clip 11 and power switch spring 21 all can be through movable core 1 with piston 4 to pressing down, make ignition terminals 19, ignition switch wiring terminal 22 break away from switch copper sheet 15, the firing circuit outage, petrol engine shuts down automatically, has prevented the generation of tile kilning.
