Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-pressure washer components, in particular to a high-pressure hose for a high-pressure washer resistant to pressure and corrosion. BACKGROUND

[0002] A high-pressure washer generates high-pressure water through a high-pressure pump or a pressure booster, which is then transmitted to a nozzle through a high-pressure hose. The high-pressure hose transmits the high-pressure water flow generated by the high-pressure pump to the nozzle to form a high-pressure water jet. This high-pressure water jet has strong impact force and can effectively flush and remove dirt, oil stains and other substances. When the high-pressure washer is not needed, the high-pressure hose is often detached and stored separately.

When the plurality of clamping blocks 305 are not clamped with the clamping hole 302, the rotating ring 303 can be stopped, and then the connecting sleeve 2 is moved to disengage the positioning column 301 and the positioning hole 307, so that the hose body 7 can be quickly disassembled, avoiding the need to use a wrench of a specific specification to twist the threaded sleeve to disassemble the hose body 7, thereby effectively shortening the disassembly time and improving the disassembly efficiency.

[0036] During installation of the hose body 7, the connecting sleeve 2 can be positioned by the plurality of positioning columns 301 passing through the positioning hole 307. When the connecting sleeve 2 moves to a certain position, the rotating ring 303 can be rotated, and the rotating ring 303 drives the plurality of clamping blocks 305 to be clamped with the clamping hole 302. At this time, the connecting sleeve 2 cannot be separated from the connecting seat 1. At this time, the sealing gasket 6 is elastically deformed after being extruded, one side of the sealing gasket 6 is tightly abutted with the connecting seat 1, and the other side is tightly abutted with the connecting sleeve 2, so that the sealing property between the connecting seat 1 and the connecting sleeve 2 can be improved, and the water leakage can be avoided.

Since the outer side of the sleeve 401 extends to the outside of the rotating ring 303, the finger can be conveniently hooked on the sleeve 401, so that the movement of the sleeve 401 is facilitated. In the movement process of the sleeve 401, the reset spring 403 is contracted. By setting the blocking ring 404, the end of the reset spring 403 can be blocked, and the moving card slot 402 of the sleeve 401 will not be with the protruding block 306 between the card. Then the rotating ring 303 can be rotated, the rotating ring 303 drives the plurality of clamping blocks 305 to move, and the positioning column 301 moves in the recess 304. When the plurality of clamping blocks 305 are not clamped between the clamping holes 302, the rotating ring 303 can be stopped, then the connecting sleeve 2 is moved to make the positioning column 301 and the positioning hole 307 disengage, so that the quick disassembly of the hose body 7 is realized, and the disassembly of the hose body 7 by means of a wrench of a specific specification is avoided, so as to effectively shorten the disassembly time and improve the disassembly efficiency.
