Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application. EMBODIMENT

[0031] Please refer to Figures 1-7 The present application provides the following technical solutions: an aircraft part spraying mechanism, comprising a spray cover body 1, a spray pipe body 2 connected to one end of the spray cover body 1, and a spray body 3 connected to the other end of the spray cover body 1 away from the spray pipe body 2, wherein the provision of the spray body 3 can provide a power source for the spraying operation, which is indispensable. A fixed mounting groove 8 is provided on the side of the spray pipe body 2 close to the spray body 3, the fixed mounting groove 8 is provided through, and return compression spring elements 14 are symmetrically arranged on the outside. Two return compression spring elements 14 are provided on each side, which have a certain contraction effect and provide favorable conditions for the normal movement of the shielding external assembly 4 during operation. The fixed mounting groove 8 has a screw rod 9 fixed therein, the outside of the screw rod 9 is sleeved with a movement limiting block 10 and a swivel ring 11, the swivel ring 11 is threadedly connected with the screw rod 9, and the movement limiting block 10 moves together with the swivel ring 11 when the swivel ring 11 rotates. The inside of the movement limiting block 10 is provided with a through hole 18, and the screw rod 9 does not contact the inner wall of the through hole 18, which provides favorable conditions for the normal movement of the movement limiting block 10.

[0032] Please refer to Figures 1-6The outer part of the spray cover body 1 is sleeved with two symmetrical shielding external components 4. In the embodiment, one side of the shielding external component 4 is integrally connected with a semicylindrical connecting threaded block 5. The outer sides of the two semicylindrical connecting threaded blocks 5 are spirally connected with a spiral sleeve body 6. The threads on the outer part of the block body combined by the two semicylindrical connecting threaded blocks 5 are matched with the threads on the inner wall surface of the spiral sleeve body 6. Meanwhile, the joint of the two shielding external components 4 is embedded with a magnetic strip, and the two parts of the magnetic strip are magnetically connected, so that the two shielding external components 4 can be closely abutted together. The side of the spiral sleeve body 6 away from the shielding external component 4 is rotationally connected with a connecting ring 7. Two transmission rods 15 are symmetrically arranged through the connecting ring 7. One end of the transmission rod 15 passes through the two shielding external components 4 and is provided with a cleaning brush body 22 at the end of the transmission rod 15. The other end of the transmission rod 15 passes through a movement limiting block 10. A matching through slot 19 is arranged at the position of the connecting ring 7 corresponding to the transmission rod 15. When the spiral sleeve body 6 is rotated, the connecting ring 7 moves under the limitation of the transmission rod 15, so that the spiral sleeve body 6 can be stably detached from the two semicylindrical connecting threaded blocks 5, and then the two shielding external components 4 can be disassembled and replaced or cleaned.

[0033] As shown in Figure 6 , a rotating groove 17 is arranged in the solid block. A screw knob 16 is rotationally arranged in the rotating groove 17. One end of the screw knob 16 is integrally formed with a cylindrical plug connecting block 20. A plug groove 21 is arranged in the transmission rod 15 corresponding to the cylindrical plug connecting block 20. One end of the cylindrical plug connecting block 20 is inserted into the plug groove 21. The combination of the transmission rod 15 and the cleaning brush body 22 can be disassembled, and the front end or the whole of the shielding external component 4 can be further brushed and cleaned.

[0034] One side of the connecting ring 7 is integrally formed with a first integral connecting piece 12. The outer side of one end of the spray pipe body 2 away from the spray cover body 1 is integrally formed with two symmetrical second integral connecting pieces 13. The two ends of the return compression spring 14 are respectively embedded into the first integral connecting piece 12 and the second integral connecting piece 13. The return compression spring 14 is arranged on both sides, so that part of the fixed mounting groove 8 can be better exposed. At this time, the rotation design of the rotating ring 11, the threaded connection between the movement limiting block 10 and the screw rod 9, and the rotation between the rotating ring 11 and the movement limiting block 10 are used, so that the movement limiting block 10 can be finely adjusted and moved along the axis of the spray pipe body 2, and can be better locked at the appropriate position. The operation is simple and fast.

[0035] As shown in Figure 1 , the cleaning brush body 22 is a fan-shaped structure, which is convenient for efficient brushing.

[0036] The working principle and use process of the present application: in the process of use, the spraying mechanism is connected with the spraying body 3 at one end, and the normal spraying operation can be realized by using the spraying pipe body 2 and the spraying cover body 1 under the action of the external power supply. When spraying the recesses on the aircraft parts, such as grooves, holes and other positions, the spraying cover body 1 needs to be inserted into the recess. At this time, the shielding external assembly 4 is blocked on the outer surface of the part, and the spraying pipe body 2 is continuously inserted, the compression spring 14 is compressed, the shielding external assembly 4 is adaptively moved, and the sputtered raw materials can also be well shielded. Due to the structural design of the recovery compression spring 14, the shielding part will not directly cover the part outside when the spraying pipe body 2 is inserted into the recess, and it is not easy to block the line of sight of the spraying operator, which will not affect the normal spraying. The above description is the existing technical means, and there is no need to make too much repetition;

[0037] At the same time, when the part of the movement limiting block 10 needs to be adjusted, the part of the rotating ring 11 is manually rotated, which can drive the part of the movement limiting block 10 to move, and then conveniently move to the appropriate position and keep a certain stability, which provides the required limiting effect for the movement of the shielding external assembly 4;

[0038] When the part of the shielding external assembly 4 is damaged, the part of the screw sleeve body 6 is manually rotated, the screw sleeve body 6 is rotatably connected between the connecting ring 7, and the transmission rod 15 is inserted into the through slot 19 of the connecting ring 7, so that the part of the semicylindrical connecting threaded block 5 is exposed, and then the two symmetrical shielding external assemblies 4 and the semicylindrical connecting threaded block 5 thereon can be separated, so that the damaged shielding external assembly 4 can be conveniently disassembled and replaced. In the daily use process, due to the protection of the part of the shielding external assembly 4, the inner wall of the shielding external assembly 4 is often stained, at this time, the part of the shielding external assembly 4 can be washed by using the external water spraying equipment, and the screw knob 16 is rotated outwardly, so that the cylindrical insertion block 20 at the end of the screw knob 16 is separated from the corresponding insertion slot 21, then the part of the transmission rod 15 is moved or rotated, and the part of the cleaning brush body 22 is rotated together, so that the inner wall of the shielding external assembly 4 is washed thoroughly. At the same time, the two shielding external assemblies 4 can be disassembled, and the combination of the transmission rod 15 and the cleaning brush body 22 can be disassembled, so that the front end or the whole of the shielding external assembly 4 can be further washed, which has high practicability;

[0039] And the transmission rod 15 is inserted between the two shielding external assemblies 4, and is also inserted between the connecting ring 7 and the movement limiting block 10, which provides favorable conditions for the stable movement of the shielding external assembly 4 along the length axis direction of the spraying pipe body 2;

[0040] Therefore, by using the above structure and connection mode, the safety and convenience of the aircraft part spraying mechanism during use are further improved, and the aircraft part spraying process can be efficiently and orderly performed.

[0041] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
