For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0027] See also Figure 1-5,The utility model provides a technical solution:

[0028] An adjustable cleaning spray rod for sanitation flushing vehicles includes a water pipe 1, a section of the water pipe 1 is rotatably connected to a connecting pipe 2, the inner wall of the connecting pipe 2 is rotatably connected to a locking assembly 3, the locking assembly 3 includes a rotating pipe 301, a plurality of card slots 302 are provided in a ring array on the outer wall of the rotating pipe 301, a through hole 303 is provided on the outer wall of the connecting pipe 2, a card ball 304 is slidably connected inside the through hole 303, a retaining ring 305 is fixedly provided on the outer wall of the connecting pipe 2, a spring 306 is fixedly welded to the side wall of the retaining ring 305 and a sleeve 307 is welded to the other end of the spring 306, a hose 4 is fixedly provided on the inner wall of the connecting pipe 2, a nozzle 5 is fixedly provided on the other end of the hose 4, and a rotating assembly 6 is fixedly provided on the side wall of the connecting pipe 2. The utility model adjusts the angle of the nozzle 5 to adapt to the roadside feet and raised stone platforms by rotating the connecting pipe 2. The connecting pipe 2 squeezes the card ball 304 to move upward, thereby driving the sleeve 307 to move. After rotating to the required position, the card ball 304 falls into the inside of the card slot 302, and the sleeve 307 is reset by the rebound force of the spring 306, thereby facilitating the rapid locking of the adjustable cleaning spray rod and delivering water to the nozzle 5 through the hose 4 for cleaning.

[0029] Specifically, the rotating assembly 6 includes two fixed bases 601, each of which is rotatably connected to a fixed shaft 602 located on the outer wall of the nozzle 5. A gear 603 is welded to the top of the outer wall of one of the fixed shafts 602. The gear 603 engages with a toothed plate 604. A cylinder 605 is fixed to the side wall of the toothed plate 604 and is electrically connected to an external power source. By turning on the cylinder 605, the toothed plate 604 moves, thereby driving the gear 603 to rotate. In turn, the fixed shaft 602 drives the nozzle 5 to rotate back and forth, facilitating the simultaneous cleaning of the curbstones from top to bottom.

[0030] Furthermore, a stop ring 308 is fixed to one end of the outer circumference of the rotating tube 301, and the stop ring 308 is rotatably connected to the inner circumference of the connecting tube 2. The stop ring 308 rotatably connected to the connecting tube 2 prevents the rotating tube 301 from being separated.

[0031] It is worth noting that the positions of the two fixed shafts 602 match, and the length of the fixing seat 601 is greater than the radius of the nozzle 5. The fixing seat 601 having a length greater than the radius of the nozzle 5 facilitates the nozzle 5 to be unobstructed when half-rotating.

[0032] It's worth noting that hose 4 is made of TPE, with the inner circumference of the hose 4 coated with an ABS base material. TPE (Thermoplastic Elastomer) is a thermoplastic elastomer material that not only possesses the high elasticity, strength, and resilience of rubber, but also has the characteristics of being injection moldable. It is also environmentally friendly, non-toxic, and safe, has a wide hardness range, excellent colorability, a soft touch, and is resistant to weather, fatigue, and temperature. The ABS base material enhances toughness.

[0033] In addition, the diameter of the locking ball 304 is greater than the height of the through hole 303, and the size and position of the locking groove 302 match the size and position of the locking ball 304. The locking ball 304, which matches the size of the locking groove 302, facilitates the rapid positioning and locking of the rotating tube 301 and the connecting tube 2.

[0034] In addition, the circuits, electronic components, and modules involved in this utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to the internal structure and method.

[0035] The device or equipment models involved in this article are as follows:

[0036] The model of cylinder 605 may be: 4-72-5 / A.

[0037] Working principle: When this device is needed to use the adjustable cleaning spray rod for sanitation washing vehicles, rotate the connecting pipe 2 and adjust the angle of the nozzle 5 to adapt to the roadside feet and irregular raised stone platforms. The connecting pipe 2 squeezes the card ball 304 to move upward, driving the sleeve 307 to move. After rotating to the required position, the card ball 304 falls into the inside of the card slot 302, and the sleeve 307 is reset by the rebound force of the spring 306. The water in the water pipe 1 is transported from the hose 4 to the nozzle 5 for cleaning. When it is necessary to clean the roadside stone platform up and down at the same time, start the cylinder 605 to drive the tooth plate 604 to move back and forth, thereby driving the gear 603 to rotate, and then the fixed shaft 602 drives the nozzle 5 to rotate back and forth.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
