[0001] The utility model relates to the technical field of nozzles, in particular to a new type of nozzle that is easy to disassemble in a radioactive environment. Background Technique

[0002] The nozzle is a very crucial component in many kinds of spraying, atomizing, oil spraying, sandblasting, spraying and other equipment, playing an important role. The nozzle is widely used in the industry, and its materials range from stainless steel, plastic to silicon carbide, aluminum alloy and tungsten steel, etc. The application scope is generally commonly used in various industries such as automobiles, electroplating, surface treatment, high-pressure cleaning, dust removal, cooling, desulfurization, humidification, stirring, gardening, etc. The existing nozzles can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] When the widely used nozzles on the market are used in a radioactive environment, the inside of the nozzle is prone to corrosion and blockage, so the nozzle needs to be replaced frequently. Most of the existing nozzle installation methods use bolt fixation, and specific tools are required for disassembly, which is time-consuming and laborious. Therefore, we propose a new type of nozzle that is easy to disassemble in a radioactive environment to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of nozzle that is easy to disassemble in a radioactive environment to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A new type of nozzle that is easy to disassemble in a radioactive environment, including a nozzle, spray ports and connectors arranged at both ends of the nozzle. An external connector is arranged inside the connector. An external thread is arranged on the outer part of the rear end of the external connector. A collar is arranged in the middle of the external connector. Activity cavities are arranged on both the upper and lower sides of the collar. Activity blocks are arranged in the two activity cavities. Plug rods are fixed at the opposite ends of the two activity blocks. Return springs are arranged at the opposite ends of the two plug rods. Push blocks are arranged on the outer walls of the rear ends of the two activity blocks. Positioning holes are arranged on both the upper and lower sides of the inner wall of the connector. The ends of the two plug rods can be inserted into the two positioning holes.

[0006] As a further preference of this technical solution, a rotating ring is rotatably connected to the outer part of the rear end of the external connector. Two baffle plates are fixed on the outer wall of the rotating ring. Convex strips are arranged on the outer walls of the two baffle plates. The two baffle plates can be rotated to the outside of the two push blocks.

[0007] As a further preference of this technical solution, the outer walls of the two activity blocks are fully attached to the inner walls of the two activity cavities on the collar, and the two activity blocks are slidably connected to the two activity cavities.

[0008] As a further preference of the present technical solution, the opposite ends of the two groups of insertion rods are both subjected to arc treatment.

[0009] As a further preference of the present technical solution, the diameter of the insertion rod is the same as the inner diameter of the positioning hole.

[0010] As a further preference of the present technical solution, both ends of the return spring are respectively connected to the outer wall of the movable block and the inner wall of the movable cavity, and the movable block forms an elastic connection with the inner wall of the movable cavity through the return spring.

[0011] As a further preference of the present technical solution, anti-slip patterns are provided on the outer walls of the two groups of push blocks.

[0012] The present utility model provides a novel nozzle that is easy to disassemble in a radioactive environment, and has the following beneficial effects:

[0013] 1. By providing two groups of positioning holes inside the connection head of the nozzle in the present utility model, in cooperation with the outer joint that can be quickly installed, when the nozzle needs to be disassembled, the two groups of push blocks can be pushed towards each other, so that the two groups of push blocks can drive the two groups of movable blocks to move towards each other, and the two groups of insertion rods can be retracted into the interior of the movable cavity. When the two groups of insertion rods completely leave the two groups of positioning holes inside the connection head, the connection between the outer joint and the nozzle can be released, and thus the nozzle and the outer joint can be quickly separated and disassembled. When the nozzle needs to be installed, the two groups of return springs are allowed to release elastic force to push the two groups of movable blocks to move away from each other, and the two groups of insertion rods are quickly inserted into the two groups of positioning holes inside the connection head, and thus the connection between the nozzle and the outer joint can be quickly completed, so that the whole nozzle can be quickly disassembled and replaced without using tools, saving time and effort, and effectively improving the convenience of the device during use.

[0014] 2. By installing a rotatable rotating ring on the outside of the outer joint and installing two groups of baffles on the rotating ring in the present utility model, the rotating ring can be driven to drive the two groups of baffles to rotate to the outside of the two groups of push blocks, so that the two groups of baffles can effectively protect the outside of the push blocks, effectively preventing external accidental touch and ensuring the stability of the device during use.

[0021] 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

[0022] The present utility model provides a technical solution: As Figures 1 to 5 shown, in this embodiment, a new type of nozzle that is easy to disassemble in a radiation environment includes a nozzle 1, nozzle orifices 2 and connectors 3 provided at both ends of the nozzle 1. An outer connector 4 is provided inside the connector 3. An external thread 5 is provided outside the rear end of the outer connector 4. A collar 6 is provided in the middle of the outer connector 4. Movable inner cavities 7 are provided on both the upper and lower sides of the collar 6. Movable blocks 8 are provided in the two movable inner cavities 7. Insertion rods 9 are fixed to the opposite ends of the two movable blocks 8. Return springs 11 are provided at the opposite ends of the two insertion rods 9. Push blocks 10 are provided on the outer walls of the rear ends of the two movable blocks 8. Positioning holes 12 are provided on both the upper and lower sides of the inner wall of the connector 3. The ends of the two insertion rods 9 can be inserted into the two positioning holes 12

[0023] By providing two positioning holes 12 inside the connector 3 of the nozzle 1 and cooperating with the outer connector 4 that can be quickly installed, when it is necessary to disassemble the nozzle 1, the two push blocks 10 can be pushed towards each other, so that the two push blocks 10 can drive the two movable blocks 8 to move towards each other, so that the two insertion rods 9 retract into the movable inner cavity 7, and the movable blocks 8 apply pressure to the two return springs 11, causing the two return springs 11 to contract and store energy. When the two insertion rods 9 completely leave the two positioning holes 12 inside the connector 3, the connection between the outer connector 4 and the nozzle 1 can be released, and thus the nozzle 1 and the outer connector 4 can be quickly separated and disassembled. When it is necessary to install the nozzle 1, the nozzle 1 can be sleeved outside the outer connector 4, and the two positioning holes 12 on the connector 3 are aligned with the two insertion rods 9. When the two positioning holes 12 move to the positions of the two insertion rods 9, the thrust on the two push blocks 10 can be released, and the two return springs 11 release their elastic force to push the two movable blocks 8 to move away from each other, so that the two insertion rods 9 quickly insert into the two positioning holes 12 inside the connector 3, and the connection between the nozzle 1 and the outer connector 4 can be quickly completed, so that the whole nozzle 1 can be quickly disassembled and replaced, effectively improving the convenience of the device during use

[0024] In other embodiments, a swivel ring 13 is rotatably connected to the outside of the rear end of the outer joint 4. Two groups of baffles 14 are fixed to the outer wall of the swivel ring 13. Convex strips 15 are provided on the outer walls of the two groups of baffles 14. The two groups of baffles 14 can be rotated to the outside of the two groups of push blocks 10.

[0025] By installing a rotatable swivel ring 13 on the outside of the outer joint 4 and installing two groups of baffles 14 on the swivel ring 13, the swivel ring 13 can drive the two groups of baffles 14 to rotate to the outside of the two groups of push blocks 10, so that the two groups of baffles 14 can effectively protect the outside of the push blocks 10, effectively preventing external accidental touch and ensuring the stability of the device during use.

[0026] In other embodiments, the outer walls of the two groups of movable blocks 8 are fully attached to the inner walls of the two groups of movable cavities 7 on the collar 6. The two groups of movable blocks 8 are slidably connected to the two groups of movable cavities 7.

[0027] Through this design, when the movable block 8 moves horizontally along the inside of the movable cavity 7, it can effectively prevent the movable block 8 from shaking during the movement, improving the stability of the device during use.

[0028] In other embodiments, the opposite ends of the two groups of insertion rods 9 are processed into arcs.

[0029] Through this design, the ends of the two groups of insertion rods 9 can quickly slide into the positioning holes 12, facilitating the docking between the insertion rods 9 and the positioning holes 12.

[0030] In other embodiments, the diameter of the insertion rod 9 is the same as the inner diameter of the positioning hole 12.

[0031] Through this design, after the end of the insertion rod 9 is inserted into the positioning hole 12, it can effectively prevent the insertion rod 9 from shaking in the positioning hole 12, improving the stability of the device during use.

[0032] In other embodiments, the two ends of the return spring 11 are respectively connected to the outer wall of the movable block 8 and the inner wall of the movable cavity 7. The movable block 8 is elastically connected to the inner wall of the movable cavity 7 through the return spring 11.

[0033] Through this design, the two groups of return springs 11 can continuously apply mutually opposite elastic forces to the two groups of movable blocks 8, enabling the two groups of movable blocks 8 to drive the insertion rods 9 thereon to quickly insert into the two groups of positioning holes 12 inside the connector 3.

[0034] In other embodiments, anti-slip patterns are provided on the outer walls of the two groups of push blocks 10.

[0035] Through this design, the friction between the two groups of push blocks 10 and the user's hand can be effectively increased, facilitating the effective pushing of the two groups of push blocks 10.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
