Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

The utility model discloses be applied to high-pressure spray gun adjust the subassembly to the position as shown in fig. 1-5, include with injection assembly fixed connection's slip pipe 41, install perpendicularly in the rotation of slip pipe 41 position 42 and be used for the fixed subassembly of fixed rotation position 42 position, rotatory can move different positions and rotate different positions round slip pipe 41 to position 42 on slip pipe 41 to make the rotation position 42 can support and lean on different health positions at operating personnel, thereby reduced high-pressure spray gun's rocking. High pressure water cleaning spray gun on the existing market needs both hands to support at operation process, and keep certain posture, just can resist great recoil effect, long-time use can make the people tired out, and even can't bear, operation form is single, this subassembly can assemble high pressure water cleaning spray gun on the existing market, assemble preceding back end to the position, the staff can adjust two kinds of mode work of shoulder centre gripping and belly support as required, high pressure water jet's recoil has been reduced, the at utmost reduces the work load that operating personnel both hands held, greatly improve cleaning efficiency.

The handle position adjusting assembly in the embodiment is used for providing two working modes of shoulder clamping and abdomen supporting, and adjusting different working modes to reduce the injection resistance of the high-pressure water cleaning spray gun; the handle position adjusting assembly adjusts the distance and the position of the rotating handle 42 in the following two ways (corresponding to the first embodiment and the second embodiment respectively), so as to generate two modes of shoulder clamping and abdomen supporting work:

example one (see fig. 1):

the fixed ring 421 of the position 42 of the rotating handle of the embodiment is provided with a threaded hole, the fixed assembly is an adjusting screw matched with the threaded hole, during adjustment, only the adjusting screw needs to be loosened, the rotating direction of the position 42 of the rotating handle is adjusted, and the adjusting screw is screwed down after the distance between the rotating handle and the front handle is adjusted, so that the position 42 of the rotating handle is fixed on the sliding tube 41, and the switching of different working modes is completed.

Example two (see fig. 2, 3):

the fixing assembly of this embodiment includes an annular shrinking wedge block 45 sleeved on the sliding tube 41 and a fixing upper cover 44 for connecting and fixing with the fixing ring 421, the annular shrinking wedge block 45 is in a horn shape with a large upper end opening and a small lower end opening, the fixing upper cover 44 is sleeved on the sliding tube 41 and is located at the front end of the annular shrinking wedge block 45, a wedge block which is inclined outwards and used for compressing the annular shrinking wedge block 45 is arranged on the inner wall of the fixing ring 421 of the rotating handle 42, when adjusting, the rotating direction of the rotating handle 42 and the distance from the front handle are adjusted, at this time, the fixing upper cover 44 is downward, the annular shrinking wedge block 45 is pressed into the fixing ring 421, and simultaneously the internal thread of the fixing upper cover 44 is adapted to the external thread on the upper portion of the fixing ring 421 (the connection mode of the fixing upper cover and the fixing ring in this embodiment is not limited to the threaded connection in this embodiment, at this time, the upper cover 44 is screwed down, the annular contracting wedge block 45 is also continuously pressed into the fixing ring 421, and the inclined wedge block on the inner wall of the fixing ring 421 enables the contracting wedge block 45 to tightly hold the sliding tube 41 to fix the rotating handle 42, thereby completing the switching of different working modes. The annular contraction wedge-shaped block 45 is annularly and uniformly distributed with strip-shaped grooves 451 used for providing contraction gaps. Through the design, when the fixed upper cover 44 and the fixed ring 421 are screwed, the annular contraction wedge-shaped block 45 has larger contraction space.

During shoulder centre gripping mode (as figure 4), unscrew adjusting screw, adjust the rotation and be the position 42 distance on the pipe that slides, adjust simultaneously the rotation position 42 and preceding position perpendicular, it is rotatory to position 42 surface adhesion or spraying elastic material, increase the operation travelling comfort, make whole rifle body keep in the armpit, it is rotatory to position 42 and shoulder contact, one only handheld position in the front, another only handheld annular knurl department in preceding barrel, but furthest reduces operating personnel's work load, greatly improve cleaning efficiency.

When the abdominal support needs to be switched to, the adjusting screw is unscrewed, the direction and the distance of the rotating handle position 42 on the sliding pipe are adjusted, after the proper distance is adjusted and the rotating handle position 42 is parallel to the front handle position, the adjusting screw is screwed down, the position and the direction of the rotating handle position 42 are fixed, and then the abdominal support mode is switched to (as shown in figure 5). During operation, whole rifle body keeps in waist abdomen position, and rotatory position 42 and the contact of waist abdomen portion are held in the front to one, and the knurling department of barrel before the other is held in the hand, but furthest reduces operating personnel's work load, greatly improves cleaning efficiency. The support part 422 of the rotating handle 42 in this embodiment is designed as an arc-shaped hollow circular tube, so that the rotating handle 42 can be attached to the body of the operator in the two working modes, and pain of the operator in contact with the rotating handle 42 when the operator is stressed is reduced.

The high-pressure water conveying assembly comprises a high-pressure hose and a high-pressure joint assembly, wherein one end of the high-pressure hose is communicated with the gun barrel, and the other end of the high-pressure hose is communicated with the high-pressure water pump; when installed, the high pressure hose passes through the sliding tube 41 and is secured in communication with the barrel by a high pressure fitting assembly. The shape of the end of the sliding pipe 41 is a horn shape with an outward opening, and due to the huge recoil generated in the high-pressure water spraying process, the high-pressure hose can not be clamped to the sliding pipe 41 when moving backwards due to the fact that the front nozzle assembly compresses the elastic piece backwards, and can freely move in the circumferential direction without direction limitation.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
