[0002] Nozzle assemblies are widely used in daily life. For example, they are installed on sanitation vehicles to wash the road surface, installed on sprinkler trucks to spray water on the road surface to cool it down, or to water green belts, etc. The nozzle assembly includes components such as pipes and nozzles. During actual use, it is often necessary to adjust the direction of the nozzle to spray water in different directions. In the prior art, universal ball joints or double flange structures are usually used to connect different pipes to adjust the direction of the nozzle spraying water. However, the universal ball joint has a small adjustable angle, the double flange structure is complex and the disassembly and assembly are unchanged, and the installation takes a long time. Therefore, the nozzle assembly in the prior art has the defects of a small adjustable angle of the nozzle and inconvenient disassembly and assembly during the adjustment process. Utility Model Content

[0003] In view of this, the utility model provides a nozzle assembly with adjustable direction and a sanitation vehicle to solve the problem that the nozzle assembly has a small adjustable angle of the nozzle and is inconvenient to assemble and disassemble during the adjustment process.

[0004] In the first aspect, the utility model provides an adjustable direction nozzle assembly, comprising: a water inlet pipe, a transfer pipe and a water outlet pipe connected in sequence, wherein the two adjacent pipes have a connected state fixedly connected to each other and a relatively rotatable split state, and at the connection of the two adjacent pipes, a first meshing portion is constructed on one of the two oppositely arranged pipe ports and a second meshing portion is constructed on the other, and the second meshing portion and the first meshing portion are engaged when the two adjacent pipes are in the connected state, and disengaged when the two adjacent pipes are in the split state; a clamp is detachably sleeved on the connection of the two adjacent pipes to switch the two adjacent pipes between the connected state and the split state; a nozzle is connected to one end of the water outlet pipe away from the transfer pipe.

[0005] Beneficial effects: By constructing one pipe port at the connection of two pipes as a first meshing portion and the other pipe port as a second meshing portion, the first meshing portion and the second meshing portion are engaged with each other to achieve the positioning connection of the two adjacent pipes, which can prevent the two adjacent pipes from rotating relative to each other when they are in a connected state, thereby improving the stability of the connected state, and by adjusting the meshing rotation direction, 360° full-angle adjustment can be achieved, and the adjustable angle of the nozzle is large, which meets the direction adjustment requirements of the nozzle. At the same time, by detachably fitting a clamp at the connection of the adjacent pipes, the two adjacent pipes can be switched between the connected state and the separated state by buckling and locking the clamp or loosening the clamp. The clamp has a simple structure and is easy to disassemble and assemble, which facilitates the adjustment of the positional relationship between the two adjacent pipes.

[0006] In an optional embodiment, both the first meshing portion and the second meshing portion are meshing teeth circumferentially arranged around the pipeline port.

[0007] Beneficial effect: By setting the first meshing portion and the second meshing portion as matching meshing teeth, the meshing teeth have good stability and high reliability after meshing, and a plurality of meshing teeth are arranged circumferentially around the pipeline port, which can ensure that the two adjacent pipelines can still be meshed together after relative rotation along the circumference of the pipeline, thereby ensuring 360° full-angle adjustment between the two adjacent pipelines.

[0008] In an optional embodiment, the meshing teeth are straight teeth or helical teeth.

[0009] Beneficial effects: Both straight teeth and helical teeth can achieve stable engagement of the two meshing parts, with a simple structure, easy processing and high reliability.

[0010] In an optional embodiment, the transfer pipe and the water outlet pipe are both curved pipes.

[0011] Beneficial effect: By setting the transfer pipe and the water outlet pipe to be curved pipes, the transfer pipe is rotated relative to the water inlet pipe and the water outlet pipe is rotated relative to the transfer pipe, so as to realize the multi-directional rotation of the nozzle in three-dimensional space. The water spraying direction can be adjusted arbitrarily according to actual needs, with high flexibility and wide application range.

[0012] In an optional embodiment, the clamp includes: two clamp parts arranged opposite to each other, the two clamp parts having a locking state for locking the two adjacent pipelines in a connected state and a disengaged state for placing the two adjacent pipelines in the split state; a locking assembly, detachably connected to the two clamp parts, so that the two clamp parts can switch between the locking state and the disengaged state.

[0013] Beneficial effect: By setting the clamp to have two relatively set clamp parts and two clamp parts, when using the clamp, it is only necessary to buckle the two clamp parts and connect and lock them through the locking assembly. The structure is simple, the operation is convenient, and it is easy to adjust the water spray assembly.

[0014] In an optional embodiment, each of the clamp parts includes a clamp body and a connecting ear, and a connecting hole is provided on the connecting ear; the locking assembly includes a bolt and a nut, and the bolt can be selectively passed through the corresponding connecting holes on the two clamp parts, and the nut is suitable for locking the bolt.

[0015] Beneficial effect: by setting a connecting hole on the connecting ear, and after the two clamps are buckled together, the connecting hole on the connecting ear of one clamp corresponds to the connecting hole on the connecting ear of the other clamp, and the bolt in the locking assembly can pass through the corresponding connecting holes on the two clamps, thereby connecting the two clamps together, and further locking the bolt with the two connecting ears connected to it through a nut, thereby locking the two clamps through the locking assembly, replacing the traditional connection method through flanges, with a simple structure and easy disassembly and assembly.

[0016] In an optional embodiment, the clamp is a groove clamp, and the clamp body has flanges protruding from the inner ring surface of the clamp on both sides along the axial direction of the clamp; the pipeline includes a pipeline body and a clamping section, the clamping section is connected to the engaging portion, and the outer diameter of the clamping section is larger than the outer diameter of the pipeline body; when the two clamps are in the locked state, an accommodating space is formed between the flanges on the two clamps, the flanges abut against the pipeline body and the clamping sections on the two adjacent pipelines are located in the accommodating space.

[0017] Beneficial effects: Grooved clamps are more common, easy to obtain, and easy to use. By constructing a clamping section with an outer diameter larger than the outer diameter of the pipeline body on the pipeline, the flange on the clamp body abuts against the pipeline body, that is, the flange is clamped to the side of the clamping section away from the meshing portion, so that after the two clamps are buckled to form a clamp, the clamping section is located in the accommodating space surrounded by the flanges on the two clamps, thereby realizing the clamp limiting the clamping section along the axial direction of the clamp, and by arranging the clamping sections on two adjacent pipelines to be located in the accommodating space of the same clamp, the two adjacent pipelines are simultaneously limited, that is, a fixed connection between the two adjacent pipelines is realized, the structure is simple, the disassembly and assembly are convenient, the fixing effect is good, and the reliability is high.

[0018] In an optional embodiment, the clamp further includes a sealing ring, which is arranged on the inner ring of the clamp and located between the two flanges on the clamp body. The inner ring of the sealing ring is provided with a sealing groove for the clamping section to be embedded.

[0019] Beneficial effect: By arranging a sealing ring on the inner side of the clamp and sleeved on the two clamping sections, that is, sleeved on the meshing part of the two adjacent pipelines, the sealing performance of the connection between the two adjacent pipelines is improved, preventing the nozzle assembly from leaking during use, and further improving reliability.

[0020] In an optional embodiment, the nozzle is a duckbill nozzle.

[0021] Beneficial effects: The duckbill nozzle has a large flow rate and good water spraying effect, which can ensure the effective use of water resources during the water spraying process, improve work efficiency and save costs.

[0022] In a second aspect, the present invention further provides a sanitation vehicle comprising the above-mentioned adjustable nozzle assembly.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] Traditional sprinkler assemblies usually use flange structures to connect adjacent pipes, such as Figure 6 As shown, a set of flanges 5 are connected between the water inlet pipe 101 and the transfer pipe 102, and between the transfer pipe 102 and the water outlet pipe 103. The flanges 5 are fixed by multiple bolts. When adjusting the water spraying direction of the nozzle 3, multiple bolts need to be disassembled and assembled. The structure is complicated, the disassembly and assembly are inconvenient, and it takes a long time.

[0034] The following combination Figures 1 to 5 , describing the embodiments of the present utility model.

[0035] According to an embodiment of the present invention, a spray head assembly with adjustable direction is provided, comprising: a water inlet pipe 101, a transfer pipe 102, and a water outlet pipe 103, which are connected in sequence; a clamp 2; and a spray head 3. Two adjacent pipes are in a state of fixed connection and a state of relative rotation. At the connection point of the two adjacent pipes, one of the two oppositely disposed pipe ports is configured with a first meshing portion 104 and the other with a second meshing portion 105. The second meshing portion 105 engages with the first meshing portion 104 when the two adjacent pipes are in the connected state and disengages when the two adjacent pipes are in the disconnected state. The clamp 2 is detachably mounted on the connection point of the two adjacent pipes to switch the two adjacent pipes between the connected state and the disconnected state. The spray head 3 is connected to the outlet pipe 103 at one end away from the transfer pipe 102. Among them, the two adjacent pipelines refer to the adjacent water inlet pipeline 101 and the transfer pipeline 102, or the adjacent transfer pipeline 102 and the water outlet pipeline 103; the two relatively arranged pipeline ports refer to the water outlet end of the previous pipeline and the water inlet end of the latter pipeline; the relative rotation of the two adjacent pipelines refers to the coincidence of the respective axes of the two pipelines, and one of the pipelines rotates around its axis.

[0036] The adjustable direction nozzle assembly of the present embodiment is applied, by constructing one pipe port at the connection of the two pipes as a first meshing portion 104 and the other pipe port as a second meshing portion 105, the positioning connection of the two adjacent pipes is achieved through the meshing of the first meshing portion 104 and the second meshing portion 105, which can prevent the two adjacent pipes from rotating relative to each other when they are in a connected state, thereby improving the stability of the connected state, and by adjusting the meshing rotation direction, 360° full angle adjustment can be achieved. The adjustable angle of the nozzle is large, which meets the direction adjustment requirements of the nozzle 3. At the same time, by detachably fitting the clamp 2 at the connection of the adjacent pipes, the two adjacent pipes can be switched between the connected state and the separated state by buckling and locking the clamp 2 or loosening the clamp 2. The clamp 2 has a simple structure and is easy to disassemble and assemble, which facilitates the adjustment of the positional relationship between the two adjacent pipes.

[0037] It should be noted that the two adjacent pipelines rotate relative to each other when in the split state, so that the meshing position between the first meshing portion 104 and the second meshing portion 105 changes, and then after the first meshing portion 104 and the second meshing portion 105 are meshed again, the relative position relationship between the two adjacent pipelines can be rotated.

[0038] In one embodiment, the first engagement portion 104 and the second engagement portion 105 are both engagement teeth circumferentially arranged around the pipeline port. Specifically, the first port of the water inlet pipe 101 is connected to the water pipe 4, the first port of the transfer pipe 102 is connected to the second port of the water inlet pipe 101, the second port of the transfer pipe 102 is connected to the first port of the water outlet pipe 103, and the second port of the water outlet pipe 103 is connected to the nozzle 3, wherein the second port of the water inlet pipe 101 is constructed with a first meshing portion 104, the first port of the transfer pipe 102 is constructed with a second meshing portion 105 and the second port is constructed with a first meshing portion 104, the first port of the water outlet pipe 103 is constructed with a second meshing portion 105, the first meshing portion 104 on the second port of the water inlet pipe 101 is meshed with the second meshing portion 105 on the first port of the transfer pipe 102, and the first meshing portion 104 on the second port of the transfer pipe 102 is meshed with the second meshing portion 105 on the first port of the water outlet pipe 103, wherein the first port and the second port are ports located at different ends of the same pipe. By setting the first meshing portion 104 and the second meshing portion 105 as matching meshing teeth, the meshing teeth have good stability and high reliability after meshing, and a plurality of meshing teeth are arranged circumferentially around the pipeline port, which can ensure that the two adjacent pipelines can still be meshed together after relative rotation along the circumference of the pipeline, thereby ensuring 360° full-angle adjustment between the two adjacent pipelines.

[0039] It should be noted that after the water flows into the water pipe 4 from the water inlet 401 of the water pipe 4, it flows into the water inlet pipe 101 through the first port of the water inlet pipe 101, and then flows through the transfer pipe 102 and the water outlet pipe 103 in sequence before being sprayed out through the nozzle 3.

[0040] In one embodiment, the meshing teeth are straight teeth or helical teeth. Both straight teeth and helical teeth can achieve stable meshing of the two meshing parts, have a simple structure, are easy to process and have high reliability.

[0041] It should be noted that the first meshing portion 104 or the second meshing portion 105 includes a plurality of meshing teeth, and the angle difference between two adjacent teeth along the circumference of the pipeline port is no more than 5°, so as to further ensure the flexibility of the adjustable angle of the nozzle 3.

[0042] In one embodiment, both the transfer pipe 102 and the outlet pipe 103 are bent pipes. Figure 2As shown, by setting the transfer pipe 102 as a curved pipe, the transfer pipe 102 rotates relative to the water inlet pipe 101, thereby driving the nozzle 3 to rotate about the first axis 601; by rotating the water outlet pipe 103 relative to the transfer pipe 102, thereby driving the nozzle 3 to rotate about the second axis 602; the centerline of the nozzle 3 coincides with the third axis 603 on the water outlet pipe 103; wherein, the angle between the first axis 601 and the second axis 602 is the bending angle of the transfer pipe 102, and the angle between the second axis 602 and the third axis 603 is the bending angle of the water outlet pipe 103. By setting both the transfer pipe 102 and the water outlet pipe 103 as curved pipes, the nozzle 3 can be rotated in multiple directions in three-dimensional space by rotating the transfer pipe 102 relative to the water inlet pipe 101 and the water outlet pipe 103 relative to the transfer pipe 102. The water spray direction can be adjusted arbitrarily according to actual needs, with high flexibility and a wide range of applications.

[0043] Preferably, the transfer pipe 102 and the water outlet pipe 103 are both 90° elbows, then the first axis 601, the second axis 602, and the third axis 603 are perpendicular to each other, so that the water spraying direction of the nozzle 3 can be adjusted in the horizontal plane and the vertical plane, and the nozzle 3 can be adjusted 360° full angle, thereby ensuring all-round water spraying.

[0044] In one embodiment, the clamp 2 includes: two opposing clamp members 210 and a locking assembly 220. The two clamp members 210 have a locking state that locks two adjacent pipelines in a connected state, and a disengaged state that separates the two adjacent pipelines. The locking assembly 220 is detachably connected to the two clamp members 210 to switch the two clamp members 210 between the locked state and the disengaged state. By configuring the clamp 2 with two opposing clamp members 210 and two clamp members 210, when using the clamp 2, it is only necessary to buckle the two clamp members 210 and connect and lock them via the locking assembly 220. This provides a simple structure, easy operation, and facilitates adjustment of the water spray assembly.

[0045] In one embodiment, each clamp member 210 includes a clamp body 211 and a connecting ear 212, and a connecting hole is provided on the connecting ear 212; the locking assembly 220 includes a bolt 221 and a nut 222, and the bolt 221 can selectively pass through the corresponding connecting holes on the two clamp members 210, and the nut 222 is suitable for locking the bolt 221. The clamp body 211 is in the form of a semicircular ring. Two clamp bodies 211 are arranged opposite each other to lock onto the pipeline. The connecting ears 212 extend outward from the outer surface of the clamp body 211. By providing connecting holes on the connecting ears 212, and after the two clamp members 210 are fastened together, the connecting holes on the connecting ears 212 of one clamp member 210 correspond to the connecting holes on the connecting ears 212 of the other clamp member 210. By providing a bolt 221 in the locking assembly 220, the bolt 221 can pass through the corresponding connecting holes on the two clamp members 210 to connect the two clamp members 210 together. The bolt 221 is further locked to the two connecting ears 212 connected to it by a nut 222, and the two clamp members 210 are locked together by the locking assembly 220, replacing the traditional connection method through flanges. The structure is simple and easy to assemble and disassemble. The outer surface of the clamp body 211 refers to the outer ring of the ring.

[0046] Specifically, each clamp 210 includes two connecting ears 212, and the number of locking assemblies 220 is two groups, that is, the clamp 2 has two groups of connecting ears 212, and the corresponding groups of connecting ears 212 on the two clamps 210 are connected through a group of locking assemblies 220.

[0047] In one embodiment, the clamp 2 is a groove clamp, and the clamp body 211 has flanges 214 protruding from the inner ring surface of the clamp part 210 on both sides along the axial direction of the clamp 2; the pipeline includes a pipeline body 110 and a clamping section 120, the clamping section 120 is connected to the meshing portion, and the outer diameter of the clamping section 120 is larger than the outer diameter of the pipeline body 110; when the two clamp parts 210 are in a locked state, an accommodating space is formed between the flanges 214 on the two clamp parts 210, the flanges 214 abut against the pipeline body 110 and the clamping sections 120 on the two adjacent pipelines are located in the accommodating space. Among them, the meshing portion refers to the first meshing portion 104 or the second meshing portion 105, and each meshing portion is connected to a clamping section 120; each clamp body 211 has two flanges 214, and the flanges 214 are located on the edges of the clamp body 211 on both sides of the axial direction of the clamp 2 and extend radially toward the center of the circle where the clamp body 211 is located; after the two clamp parts 210 are buckled together to form the clamp 2, the corresponding flanges 214 on the two clamp parts 210 are spliced to form a closed circle.

[0048] Groove clamps are more common, easy to obtain, and easy to use. By constructing a clamping section 120 with an outer diameter larger than the outer diameter of the pipe body 110 on the pipeline, the flange 214 on the clamp body 211 abuts against the pipe body 110, that is, the flange 214 is clamped to the side of the clamping section 120 away from the meshing portion, so that after the two clamp parts 210 are buckled to form the clamp 2, the clamping section 120 is located in the accommodating space surrounded by the flanges 214 on the two clamp parts 210, thereby realizing the axial limitation of the clamping section 120 by the clamp 2, and by arranging the clamping sections 120 on two adjacent pipelines to be located in the accommodating space of the same clamp 2, the simultaneous limitation of the two adjacent pipelines is realized, that is, a fixed connection between the two adjacent pipelines is realized, the structure is simple, the disassembly and assembly are convenient, the fixing effect is good, and the reliability is high.

[0049] In one embodiment, the clamp 2 further includes a sealing ring 230, which is disposed on the inner ring of the clamp 210 and located between the two flanges 214 on the clamp body 211. The inner ring of the sealing ring 230 is provided with a sealing groove 231 for the clamping section 120 to be embedded in. During installation, the sealing ring 230 is simply placed on the connection between the two adjacent pipelines and fastened and compressed using the groove clamp to complete the installation. By providing the sealing ring 230 on the inner side of the clamp 2 and fitting it onto the two clamping sections 120, that is, fitting the sealing ring 230 onto the meshing portion of the two adjacent pipelines, the sealing performance of the connection between the two adjacent pipelines is improved, water leakage during use of the spray head assembly is prevented, and reliability is further improved.

[0050] In one embodiment, the nozzle is a duckbill nozzle, which has a large flow rate and good water spraying effect, can ensure the effective use of water resources during the water spraying process, improve work efficiency, and save costs.

[0051] According to an embodiment of the present invention, on the other hand, a sanitation vehicle is provided, comprising: the above-mentioned direction-adjustable nozzle assembly.

[0052] The direction-adjustable nozzle assembly of this embodiment can realize the direction adjustment and fixation between two adjacent pipelines by designing matching meshing teeth at the mating ends of two adjacent pipelines, thereby realizing the direction adjustment requirement of the nozzle 3; and a groove clamp is used to connect the two adjacent pipelines at the connection point, replacing the traditional connection method through the flange 5; a structural clamp form of a groove clamp and a matching sealing ring 230 is used to replace the traditional double flange and O-ring structure to seal the connection part between the two adjacent pipelines, which has low cost, simple structure, convenient disassembly and assembly, and simple and labor-saving adjustment of the water spraying direction of the nozzle 3.

[0053] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
