Abstract
The utility model relates to a spray gun shutoff device for a high-pressure washer. The spray gun shutoff device comprises a safety valve rod, a return spring, a seal ring, an unloading valve cap, a switch box and a power cut contact, wherein the safety valve rod, the unloading valve cap and the power cut contact are coaxially arranged. The spray gun shutoff device can be directly installed in a high-pressure washer and is positioned on the rear side of a valve rod, and the valve rod is propped against on a movable end of the safety valve rod in the spray gun shutoff device; a push inclined surface at a pushing end of the power cut contact terminal in the spray gun shutoff device is positioned in front of a contact of a microswitch in the high-pressure washer, and the microswitch is connected with a power source of the high-pressure washer. When a high-pressure water pump is shut off, the valve rod pushes the safety valve rod in the spray gun shutoff device backwards, the safety valve rod drives the power cut contact to act, to push the contact of the microswitch, so as to shut off the power supply of a motor while the spray gun of the high-pressure washer is shut off, thereby greatly reducing the friction loss generated in the pump, and the service life of parts and accessories in the pump can be obviously enhanced.

Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, a kind of compact conformation is provided, can cooperates with jetting machine, realizes closing the pass rifle arresting gear that spray gun trigger is the purpose of automatic powered-down.
For achieving the above object; the utility model adopts a kind of pass rifle arresting gear of jetting machine; comprise safety lever; back-moving spring; sealing ring; the off-load bonnet; switch enclosure; the outage contact; safety lever; off-load bonnet and the coaxial setting of outage contact three; one end of off-load bonnet forms the endoporus step; the other end forms lower counterbore; be connected by through hole between endoporus step and the lower counterbore; the safety lever shape is cylindricality; comprise movable end and positive stop end; safety lever passes the through hole of off-load bonnet; the movable end of safety lever and positive stop end are positioned at off-load bonnet both sides; form step on the movable end of safety lever; back-moving spring is set on the safety lever; back-moving spring one end is pressed on the step of safety lever; the other end is pressed on the endoporus step of off-load bonnet; corresponding endoporus step one side is provided with sealing ring in the through hole of off-load bonnet; switch enclosure is arranged in the lower counterbore of off-load bonnet; offer jack in the switch enclosure vertically; outage contact front end offers and the suitable endoporus of the positive stop end of safety lever; outage contact lower end forms the promote-side; the outage contact inserts in the jack of switch enclosure, and the positive stop end of safety lever stretches in the endoporus of outage contact and constitutes the spacing cooperation of step with it.
For fixed reset spring better; make it reliable operation; the utility model further is set to close the rifle arresting gear and comprises spring pressuring ring, and spring pressuring ring is arranged on the endoporus step of off-load bonnet and is positioned at the sealing ring front end, and the rear end of back-moving spring is pressed on the spring pressuring ring.
For the outage contact is cooperated with microswitch on the jetting machine better, the utility model is set to further that the formation of one side pushes away the inclined-plane in the promote-side of outage contact.
The utility model closes the rear side that the rifle arresting gear can directly be packed in the jetting machine and is positioned at valve rod; valve rod withstands on the movable end that closes the safety lever in the rifle arresting gear; close the outage contact in the rifle arresting gear the promote-side push away contact the place ahead that the inclined-plane is positioned at the jetting machine microswitch, the motor power of microswitch connection jetting machine.When high-pressure hydraulic pump closes rifle; valve rod promotes to close the safety lever in the rifle arresting gear backward; safety lever drives the action of outage contact; promote the contact of microswitch; make jetting machine when closing spray gun, disconnect motor power, finish close rifle after power cutoff carry out simultaneously; reduce the sassafras loss that rubs that produces in the pump greatly, the part and accessory life-span is able to obvious raising in the pump.And solved simultaneously and close the hydraulic giant trouble of powered-down more subsequently in the operation, bring convenience to operation, but saves energy and reduce noise, and improve the reliability of whole jetting machine.
