[0002] The nozzle is a key component in many types of spraying, misting, oiling, sandblasting, spraying and other equipment, and plays an important role. The nozzle is widely used in the industry. The materials range from stainless steel, plastic to silicon carbide, polytetrafluoroethylene, aluminum alloy and tungsten steel, etc. The application range is generally commonly used in various industries such as automobiles, electroplating, surface treatment, high-pressure cleaning, dust removal, cooling, desulfurization, humidification, mixing, gardening, etc. The existing spray pipe nozzles can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] The widely used spray pipe nozzles on the market are prone to radioactive substances being adsorbed on the nozzle surface when used in a radiation environment. When the radioactive substances are in contact with the nozzle surface for a long time, the nozzle surface is easily corroded and needs to be replaced in time. During the nozzle replacement process, the human body is prone to accidentally touch the nozzle surface, which poses a certain safety hazard. For this reason, we propose a new type of spray pipe nozzle for radiation environment to solve the above problem. Utility Model Content

The front end of the spray pipe end 4 is provided with four groups of guide grooves 14. The four groups of limit blocks 15 can all be inserted into the limit blocks 15.

[0021] When the device is used, the spray pipe end 4 can be installed on the external spray pipe first, and then the connection port 2 on the spray pipe nozzle 1 can be put on the outside of the spray pipe end 4, so that the four groups of limit blocks 15 inside the spray pipe nozzle 1 are aligned with the four groups of guide grooves 14 on the spray pipe end 4, and then the spray pipe nozzle 1 can be pushed in the reverse direction of the spray pipe end 4, so that the spray pipe nozzle 1 drives the four groups of limit blocks 15 to slide along the four groups of guide grooves 14 on the spray pipe end 4, and the limit blocks 15 can be driven by the spray pipe nozzle 1 to slide along the four groups of guide grooves 14 on the spray pipe end 4. During the movement of 5, the inner wall of the connecting port 2 pushes the top plate 5, so that the top plate 5 drives the four sets of guide slide bars 10 to slide along the guide slide holes 9 on the sleeve 8, and the return springs 12 outside the four sets of guide slide bars 10 are squeezed and deformed by the top plate 5 to store force. When the limit block 15 moves to the end of the guide groove 14, the four sets of protrusions 3 are also inserted into the four sets of through grooves 6 on the top plate 5, and then the spray pipe nozzle 1 can be rotated clockwise to allow the four sets of limit blocks 15 to enter the extension groove of the end of the guide groove 14. The four groups of bosses 3 are moved into the slot, and the four groups of bosses 3 are displaced along the through slot 6 and the water drop-shaped hole 7. The four groups of bosses 3 are moved to the ends of the four groups of water drop-shaped holes 7. The four groups of water drop-shaped holes 7 form a connection between the spray pipe nozzle 1 and the top plate 5. The installation of the spray pipe nozzle 1 can be completed. When the spray pipe nozzle 1 needs to be disassembled, a wrench can be used to cover the hexagonal flat head cap 13 outside the spray pipe nozzle 1, and the wrench can be turned counterclockwise to rotate the spray pipe nozzle 1 counterclockwise, so that the spray pipe nozzle 1 can drive The four groups of protrusions 3 move to the large end of the teardrop-shaped hole 7, and the return springs 12 outside the four groups of guide slide bars 10 release the elastic force to push the top plate 5, so that the top plate 5 pushes the spray pipe nozzle 1 outside the spray pipe end head 4 to move forward, allowing the spray pipe nozzle 1 to be quickly ejected from the spray pipe end head 4, allowing the spray pipe nozzle 1 to quickly detach from the spray pipe end head 4, without the need for hands to contact the surface of the spray pipe nozzle 1, and at the same time facilitating and quickly disassembling the spray pipe nozzle 1, thereby improving the safety during device replacement.

[0022] In other embodiments, the protrusions 3 in the four sets of connection ports 2 can all be inserted into the through slots 6;

[0023] With this design, the spray pipe nozzle 1 can drive the four groups of bosses 3 to quickly align with the four types of through grooves 6 on the top plate 5, thereby facilitating the four groups of bosses 3 to quickly enter the four groups of through grooves 6.

[0027] In other embodiments, the outer diameter of the guide slide rod 10 is the same as the inner diameter of the guide slide hole 9 on the sleeve 8, and the guide slide rod 10 and the guide slide hole 9 on the sleeve 8 form a sliding connection.

[0028] With this design, when the guide slide rod 10 slides along the guide slide hole 9 on the sleeve 8, it can effectively prevent the top plate 5 from shaking, ensuring that the top plate 5 can push the spray pipe nozzle 1 outward.

[0029] In other embodiments, the diameter of the positioning plate 11 is larger than the diameter of the guide sliding hole 9 on the sleeve 8;

[0030] This design can prevent the guide slide rod 10 from being separated from the guide slide hole 9 on the sleeve 8, thereby ensuring that the top plate 5 can be normally sleeved on the outside of the spray pipe end 4.

[0031] In other embodiments, the inner wall of the through groove 6 is provided with an anti-slip rubber pad;

[0032] With this design, when the boss 3 is inserted into the through groove 6 , the friction between the inner wall of the through groove 6 and the outer wall of the boss 3 can be increased, thereby preventing the spray pipe nozzle 1 from reversing.
