[0001] This utility model relates to the field of water jet loom technology, specifically a nozzle for a water jet loom. Background Technology

[0002] As a key piece of equipment widely used in the textile industry, the water jet loom's nozzle assembly is the core component for realizing water jet weft insertion and ensuring the quality and efficiency of fabric weaving. During the long-term operation of the water jet loom, the nozzle body needs to continuously withstand the impact of high-pressure water flow, and is prone to problems such as reduced water spray accuracy and abnormal water atomization due to factors such as the accumulation of impurities in the water and wear from loom vibration. Therefore, it is necessary to regularly disassemble, inspect, clean, or replace the nozzle body to maintain the stable operation of the loom.

[0003] Currently, most water jet loom nozzles on the market use traditional bolt fastening and snap-fit ​​designs for installation and fixing. Some nozzles use multiple sets of bolts to lock the nozzle body to the mounting base, requiring the use of wrenches and other tools to loosen the bolts one by one during disassembly, which is a cumbersome process.

[0004] Therefore, we propose a water jet loom to solve the above problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a water jet loom nozzle includes a mounting base 1 and a nozzle body 2. A groove 3 is machined on one side of the mounting base 1. One end of the nozzle body 2 is installed inside the groove 3. A prism groove 4 is machined on one end of the groove 3. A prism head 201 is provided at one end of the nozzle body 2, and one end of the prism head 201 is plugged into the prism groove 4. A handle 6 is provided on one side of the mounting base 1. One end of the handle 6 is fixedly connected to a limit ring 7, and one side of the limit ring 7 is fixed... A connecting shaft 8 is connected, one end of the connecting shaft 8 is movably connected to a sleeve 9, one end of the sleeve 9 is fixedly connected to a gear 10, both ends of the gear 10 are meshed with a rack 11, one end of the rack 11 is fixedly connected to a connecting block 12, one end of the connecting block 12 is fixedly connected to a locking tongue 13, one end of the locking tongue 13 is snapped into the middle of the nozzle body 2, and one end of the prism groove 4 is fixedly connected to a water inlet 5, which is plugged into the inside of the prism head 201. When the nozzle body 2 needs to be installed, one end of the nozzle body 2 is inserted into the interior of the groove 3, and one end of the prism head 201 is inserted into the interior of the prism groove 4. Due to the prism structure of the prism head 201 and the prism groove 4, the rotation of the nozzle body 2 can be restricted. When the nozzle body 2 enters the interior of the prism groove 4, the prism head 201 will press the locking tongue 13, causing the locking tongue 13 to retract into the interior of the movable groove 15. When the prism head 201 is completely inserted into the interior of the prism groove 4, the locking tongue 13 resets to limit and fix the nozzle body 2. At the same time, the water inlet 5 is inserted into the interior of the prism head 201 and communicates with the prism head 201. A rubber ring is provided on the outside of the water inlet 5 to seal the connection between the water inlet 5 and the prism head 201. When it is necessary to disassemble the nozzle body 2, pull the handle 6 outward. The handle 6 will drive the limiting ring 7 and the connecting shaft 8 to move outward. Then rotate the handle 6. The handle 6 will drive the limiting ring 7 to rotate. The limiting ring 7 will drive the connecting shaft 8 to rotate. The connecting shaft 8 will drive the sleeve 9 to rotate through the slider 18. The sleeve 9 will drive the gear 10 to rotate. The rotation of the gear 10 will drive the two racks 11 to move. The racks 11 will drive the connecting block 12 to move. The connecting block 12 will drive the locking tongue 13 to move, so that the locking tongue 13 will disengage from the middle of the nozzle body 2, thereby releasing the limiting of the nozzle body 2 and making it easy to disassemble and remove the nozzle body 2. Furthermore, a limiting groove 14 is machined on one side of the mounting base 1, and a limiting ring 7 is plugged into the inside of the limiting groove 14. When the handle 6 moves the limiting ring 7 outward, the limiting ring 7 disengages from the inside of the limiting groove 14, releasing the limiting ring 7 from its position, thereby allowing the handle 6 and the limiting ring 7 to rotate. Furthermore, the inner walls on both sides of the groove 3 of the mounting base 1 are machined with movable grooves 15. The locking tongue 13 is movably connected to the inside of the movable groove 15. When the locking tongue 13 moves, the locking tongue 13 will move along the inside of the movable groove 15. The movable groove 15 will limit the movement of the locking tongue 13, so that the locking tongue 13 remains stable when it moves. Furthermore, a connecting groove 16 is machined at one end of the movable groove 15, and the connecting block 12 is movably connected inside the connecting groove 16. When the connecting block 12 moves, the connecting block 12 will move along the inside of the connecting groove 16, and the connecting groove 16 will limit the movement of the connecting block 12. Furthermore, a return spring 17 is provided inside the sleeve 9. One end of the return spring 17 is fixedly connected to the inner wall of one end of the sleeve 9, and the other end of the return spring 17 is fixedly connected to one end of the connecting shaft 8. With the return spring 17 provided, when the handle 6 is pulled, the connecting shaft 8 drives the return spring 17 to stretch, and the limiting ring 7 will disengage from the inside of the limiting groove 14. When the handle 6 is released, the return spring 17 returns to its original position and contracts. The return spring 17 will drive the connecting shaft 8 to move, thereby allowing the limiting ring 7 to insert into the inside of the limiting groove 14. Furthermore, one end of the connecting shaft 8 is fixedly connected to two sliders 18, and the inner wall of the sleeve 9 is machined with two grooves 19. The sliders 18 are movably connected to the grooves 19. When the limiting ring 7 drives the connecting shaft 8 to move, the connecting shaft 8 will drive the sliders 18 to move. The sliders 18 will move along the inside of the grooves 19. The grooves 19 will limit the movement of the connecting shaft 8 through the sliders 18, so that the limiting ring 7 will drive the sleeve 9 to rotate through the connecting shaft 8.

[0018] Working principle: When it is necessary to disassemble the nozzle body 2, pull the handle 6 outward. The handle 6 will drive the limiting ring 7 and the connecting shaft 8 to move outward. Then rotate the handle 6. The handle 6 will drive the limiting ring 7 to rotate. The limiting ring 7 will drive the connecting shaft 8 to rotate. The connecting shaft 8 will drive the sleeve 9 to rotate through the slider 18. The sleeve 9 will drive the gear 10 to rotate. The rotation of the gear 10 will drive the two racks 11 to move. The racks 11 will drive the connecting block 12 to move. The connecting block 12 will drive the locking tongue 13 to move, so that the locking tongue 13 is disengaged from the middle of the nozzle body 2, thereby releasing the limiting of the nozzle body 2 and facilitating quick disassembly and removal of the nozzle body 2.
