Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a vehicle urea nozzle that is easy to disassemble and install. Background Technology

[0002] With the deterioration of the atmospheric environment, selective catalytic reduction (SCR) aftertreatment systems have been widely used as a major aftertreatment technology to effectively reduce nitrogen oxides in exhaust gases. SCR is currently recognized as one of the most effective aftertreatment technologies for reducing NOx emissions from diesel engines.

[0003] Urea SCR involves injecting a certain amount of urea solution into the exhaust pipe. The urea solution then undergoes evaporation, pyrolysis, and hydrolysis to produce the reducing agent NH3. Under the action of a catalyst, NH3 selectively reduces NOx to N2, thereby reducing the NOx content in the exhaust. The urea injector, as a crucial component, has always received considerable attention. However, the installation method of existing automotive urea injectors is rather cumbersome, requiring a significant amount of time for assembly. Furthermore, disassembly and repair are time-consuming and labor-intensive for workers, reducing their work efficiency. Utility Model Content

[0025] Example 1

[0026] like Figures 1-4 As shown:

[0027] A vehicle urea nozzle that is easy to disassemble and install includes a nozzle 1, a urea nozzle body 2, and a connecting block 3. One end of the urea nozzle body 2 is fixed with the nozzle 1, and the other end of the urea nozzle body 2 is threadedly connected to the connecting block 3.

[0028] Specifically, a threaded groove 8 is provided on the inner surface of the connecting block 3, and a threaded sleeve 5 is fixedly connected to the outer surface of the urea nozzle body 2. The outer surface of the threaded sleeve 5 is threadedly connected to the inner wall of the threaded groove 8, thereby realizing the threaded connection between the urea nozzle body 2 and the connecting block 3, which facilitates disassembly and installation.

[0029] A limiting component is also provided between the urea nozzle body 2 and the connecting block 3. The limiting component includes a fixed plate 4 and a rotating ring 6 fixedly connected to the outer surface of the urea nozzle body 2. A slot 9 is provided on the outer surface of the connecting block 3. The inner wall of the slot 9 is engaged with the outer wall of the rotating ring 6. A limiting screw hole is provided on the inner wall of the slot 9. A limiting bolt 10 is threadedly connected to the limiting screw hole.

[0030] A rotating ring 6 is fitted onto the outer surface of the fixed disk 4. A rotating groove 7 is formed on the inner wall of the rotating ring 6. The outer surface of the fixed disk 4 is rotatably connected to the inner wall of the rotating groove 7, allowing the rotating ring 6 to rotate freely relative to the fixed disk 4. Positioning blocks 11 are fixedly connected to opposite ends of the outer surface of the rotating ring 6. One of the positioning blocks 11 has a circular through hole on its outer surface, through which a limiting bolt 10 can pass. The limiting bolt 10 connects the positioning block 11 to the limiting screw hole.

[0031] A loop frame 12 is fixedly connected to the side of the connecting block 3 opposite to the limiting screw hole. A pull plate 13 is provided on the outer surface of the loop frame 12. A slide rod 14 is fixedly connected to the outer surface of the pull plate 13. A spring 15 is sleeved on the outer surface of the slide rod 14. One end of the spring 15 is fixedly connected to the inner wall of the loop frame 12. A limiting block 16 is fixedly connected to one end of the spring 15.

[0032] In this embodiment, the rotating ring 6 is made of steel, specifically spring steel sheet, which has good rigidity. At the same time, the positioning blocks 11 on both sides of the rotating ring 6 have a certain elasticity, and the positioning blocks 11 can be pressed into the inner side of the limiting block 16 by pressing.

[0033] The rotating ring 6 is rotatably connected to the fixed plate 4 via the rotating groove 7. The fixed plate 4 limits the rotation of the rotating ring 6, preventing it from moving back and forth and allowing it to rotate. This ensures that the positioning blocks 11 installed on both sides of the rotating ring 6 can align with the two ends of the slot 9. When the movable block 3 is tightened in place, the rotating ring 6 and the slot 9 are engaged. The positioning rings 11 at both ends of the rotating ring 6 are fixed to the slot 9, thus limiting the movable block 3 and preventing it from falling off the urea nozzle body 2. Specifically, the positioning block 11 is connected to the limiting screw hole on the slot 9 by the limiting bolt 10, thus fixing the rotating ring 6 and ensuring that the rotating ring 6 will not rotate during operation. At the same time, another positioning block 11 on the rotating ring 6 is snapped into the inside of the limiting block 16. Through the cooperation of the two positioning blocks 11, the movable block 3 is limited by the rotating ring 6, preventing it from falling off the urea nozzle body 2.

[0034] When using this utility model:

[0035] like Figures 1-4 As shown, firstly, the threaded sleeve 5 on the outer surface of the urea nozzle body 2 is threadedly connected to the threaded groove 8 on the inner surface of the connecting block 3, thus initially realizing the connection between the urea nozzle body 2 and the connecting block 3; the rotating ring 6 is rotatably connected to the fixed disk 4 through the rotating groove 7, so that the rotating ring 6 can rotate normally, and the positioning block 11 is moved by the rotation of the rotating ring 6.

[0036] When the connecting block 3 rotates relative to the urea nozzle body 2 to a position close to the fixed plate 4, the positioning block 11 with the circular hole on the rotating ring 6 is connected to the limiting screw hole on the inner wall of the slot 9 through the limiting bolt 10, thereby limiting the rotating ring 6. When the rotating ring 6 is engaged with the slot 9 and moves, pressing down on another positioning block 11 will squeeze the limiting block 16, causing the limiting block 16 to move. At the same time as the limiting block 16 moves, it squeezes the spring 15, and the slide rod 14 also moves accordingly. When the positioning block 11 passes the limiting block 16, the spring 15 will rebound and drive the limiting block 16 to reset, thereby blocking the positioning block 11 and fixing the urea nozzle body 2, thus completing the quick installation of the urea nozzle. When the operator needs to disassemble the urea nozzle, the operator pulls the pull plate 13 to release the limiting block 16 from the positioning block 11, thereby facilitating the disassembly of the urea nozzle.

[0037] This utility model achieves the fixation of the urea nozzle body by setting a threaded sleeve and a threaded hole for threaded connection, thereby enabling workers to install quickly and improving work efficiency. The urea nozzle body 2 sprays urea liquid, and the nozzle head 1 ensures that the urea nozzle can work normally and that the vehicle can be used normally. The connecting block 3 facilitates the quick installation of the urea nozzle body by workers. By setting a slot 9 and engaging with the rotating ring 6, a secondary fixation of the urea nozzle body 2 is achieved, ensuring that the urea nozzle body will not fall off during operation and facilitating the disassembly and maintenance of the urea nozzle by workers. The U-shaped frame 12 provides a good installation environment for other components. A pull plate 13 is set to drive the slide rod 14 to move, which facilitates the disassembly of the urea nozzle body 2 by workers. A slide rod 14 is set to drive the movement of the limiting block 16. A spring 15 is set to drive the movement of the limiting block 16. The limiting block 16 limits the rotating ring 6, thereby fixing the urea nozzle body 2.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
