[0002] A fan nozzle is a commonly used nozzle type in engineering design. Its nozzle opening shape is arc-shaped or fan-shaped, and the nozzle opening width is larger than that of traditional circular nozzles. It can be used to evenly spray liquids or gases. This design enables the nozzle to cover a wider area, and is commonly found in irrigation systems, painting equipment, and air cooling systems, improving the spraying efficiency and coverage area.

[0003] In the prior art, the fan nozzles usually have pre-drilled screw holes, and the nozzles are fixed on brackets or mounting seats through bolts. However, the nozzles fixed by mounting bolts usually require tools to tighten the bolts, thus requiring more steps for installation and replacement. Moreover, due to vibrations in the environment or loosening during use, the bolts-fixed nozzles need to be re-tightened. To solve the above problems, the technical personnel in this field have proposed a positioning and installation structure of a fan nozzle. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a positioning and installation structure of a fan nozzle, aiming to improve the problem that the fan nozzles in the prior art usually require tools to tighten bolts for installation.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figure 1 , an embodiment provided by the present utility model: a sector nozzle positioning and installation structure, including a nozzle body 1, a plurality of guide blocks 2 are fixedly connected to the outside of the nozzle body 1, and the plurality of guide blocks 2 are axially symmetrically distributed along the center point of the nozzle body 1. A connector 3 is slidably connected to the outside of the nozzle body 1, an installation block 4 is fixedly connected to the front end of the connector 3, and the outside of the nozzle body 1 is slidably connected to the inside of the installation block 4. A plurality of guide grooves 5 are opened in the inside of the connector 3 and the installation block 4, and the outside of the guide block 2 is slidably connected to the inside of the guide groove 5.

[0027] Specifically, the connector 3 and the installation block 4 play a limiting role on the nozzle body 1, so that the nozzle body 1 will not deviate when moving. The plurality of guide blocks 2 on the nozzle body 1 move in the guide grooves 5 in the connector 3 and the installation block 4, so that the nozzle body 1 can be stabilized inside the connector 3 and the installation block 4.

[0028] Referring to Figures 1 - 3, on both the left and right sides inside the mounting block 4, limiting grooves 6 are provided. On the inner wall of the limiting groove 6, a first spring 7 is fixedly connected. The adjacent ends of the two first springs 7 are both fixedly connected with a first limiting block 8. The inner part of the limiting groove 6 is slidably connected to the outer part of the first limiting block 8. The separated ends of the two first limiting blocks 8 are both fixedly connected with a clamping block 9. The inner part of the limiting groove 6 is slidably connected to the outer part of the clamping block 9. On both the left and right sides inside the nozzle body 1, clamping grooves 10 are provided. The outer part of the clamping block 9 is engaged with the inner part of the clamping groove 10. The separated sides of the two first limiting blocks 8 are both fixedly connected with a pull rope 11. The inner part of the mounting block 4 is slidably connected to the outer part of the pull rope 11. The adjacent ends of the two pull ropes 11 are fixedly connected with a rotating rod 12. The inner part of the mounting block 4 is rotatably connected to the outer part of the rotating rod 12.

[0029] Specifically, the limiting groove 6 and the first limiting block 8 fix the first spring 7, enabling the first spring 7 to stably undergo elastic deformation. The limiting groove 6 limits the first limiting block 8 and the clamping block 9, preventing the first limiting block 8 and the clamping block 9 from shifting during movement. Through the engagement of the clamping block 9 with the clamping groove 10, the nozzle body 1 is fixed within the mounting block 4. The first limiting block 8 limits the pull rope 11 and the rotating rod 12, ensuring the stability of the pull rope 11 during movement and the rotating rod 12 during rotation. By rotating the rotating rod 12, the two pull ropes 11 are driven to move towards the adjacent side, thereby driving the two first limiting blocks 8 to move towards the separated side, and further driving the two clamping blocks 9 to move accordingly, so that the clamping block 9 is disengaged from the clamping groove 10, and thus the nozzle body 1 can be conveniently taken out for maintenance.

[0030] Refer to Figures 4 - 6 , on the outer part of the nozzle body 1, a sealing groove 13 is provided. Inside the connecting member 3, a sealing assembly 14 is provided. The sealing assembly 14 seals the connection between the nozzle body 1 and the connecting member 3. The sealing assembly 14 includes a mounting groove 1401, which is provided inside the connecting member 3. On the inner wall of the mounting groove 1401, a plurality of second springs 1402 are fixedly connected. The plurality of second springs 1402 are axially symmetrically distributed along the center point of the connecting member 3. The inner sides of the plurality of second springs 1402 are fixedly connected with a second limiting block 1403. The inner part of the mounting groove 1401 is slidably connected to the outer part of the second limiting block 1403. The inner side of the second limiting block 1403 is fixedly connected with a sealing ring 1404. The inner part of the mounting groove 1401 is slidably connected to the outer part of the sealing ring 1404. The outer part of the sealing ring 1404 abuts against the inner part of the sealing groove 13.

[0031] Specifically, during installation, the spring 1402 is elastically deformed, so that the spring 1402 can be reset inside the installation groove 1401. The installation groove 1401 and the limit block 1403 fix the spring 1402, so that the spring 1402 can be stably reset. The installation groove 1401 limits the limit block 1403 and the sealing ring 1404, so that the limit block 1403 and the sealing ring 1404 will not deviate when moving. The limit block 1403 is inside the installation groove 1401, so that the sealing ring 1404 will not be separated from the installation groove 1401. The sealing ring 1404 abuts against the sealing groove 13, so that the connection between the nozzle body 1 and the connecting member 3 is sealed.

[0032] Working principle: When the nozzle body 1 needs to be installed and fixed, the two pull ropes 11 are driven to move toward the adjacent side by rotating the rotating rod 12, thereby driving the two limit blocks 8 to move toward the separated side, and then squeezing the spring 7 to make elastic deformation, thereby driving the two clamping blocks 9 to move toward the separated side, and then placing the nozzle body 1 inside the connecting piece 3, so that the spring 7 performs a reset activity, thereby driving the two limit blocks 8 to move toward the adjacent side, thereby driving the clamping block 9 to move with it into the clamping groove 10, and then making the clamping block 9 engage with the clamping groove 10, so that the nozzle body 1 can be conveniently installed and fixed;

[0033] In addition, when it is necessary to seal the connection between the nozzle body 1 and the connecting piece 3, the spring 2 1402 is elastically deformed during installation, so that the spring 2 1402 performs a reset activity to drive the limit block 2 1403 to move toward the inside of the connecting piece 3, thereby driving the sealing ring 1404 to move with it, so that the sealing ring 1404 can fit tightly with the sealing groove 13, thereby completing the sealing of the connection between the nozzle body 1 and the connecting piece 3.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
