[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figures 1 to 5 The pneumatic needle rust removal device shown includes a housing assembly 1, a vibration damping assembly 2, a pushing assembly 3, a quick-release assembly 4, and a rust removal assembly 5. The vibration damping assembly 2 is provided inside the housing assembly 1, and the pushing assembly 3 is provided on one side of the vibration damping assembly 2. The quick-release assembly 4 is provided on the side of the pushing assembly 3 away from the vibration damping assembly 2, and the rust removal assembly 5 is installed inside the quick-release assembly 4.

[0025] Among them: the vibration damping component 2 can reduce the vibration generated by the equipment during use and improve the user experience. The quick-release component 4 allows the equipment to quickly replace the rust removal facilities, thereby speeding up the work efficiency. Furthermore, the rust removal component 5 can be quickly fixed or replaced, further accelerating the work efficiency.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0028] In a preferred embodiment, the housing assembly 1 includes an air inlet 11, a cylindrical handle 12, and a metal shell 13, with the cylindrical handle 12 mounted on one side of the air inlet 11 and the metal shell 13 mounted on the side of the cylindrical handle 12 away from the air inlet 11.

[0029] In a preferred embodiment, the vibration damping component 2 includes a fixed frame 21, a cylindrical groove 22, a fixed shaft 23, and a metal ring 24. The fixed frame 21 has a cylindrical groove 22 inside, and the fixed shaft 23 is fixed inside the cylindrical groove 22. The outer diameter surface of the fixed shaft 23 is fitted with a metal ring 24. When the device is running, the vibration effect is transmitted from the device body to the handle position. At this time, the metal ring 24 fitted on the fixed shaft 23 fixed inside the cylindrical groove 22 will absorb part of the vibration potential energy. In addition, the handle is also fitted with a soft material to achieve the vibration damping effect.

[0030] In a preferred embodiment, the pushing component 3 includes an air chamber 31, a cylindrical shell 32, a piston 33, a sealing ring 34, a first spring 35, and an exhaust port 36. The cylindrical shell 32 is installed on one side of the air chamber 31, and the piston 33 is disposed inside the cylindrical shell 32. The sealing ring 34 is fixed on the outer diameter surface of the piston 33, and the first spring 35 is fixed at the edge of the piston 33. The exhaust port 36 is opened through the outer wall of the cylindrical shell 32. When the airflow enters the air chamber 31, the air pressure will push the piston 33 and compress the first spring 35. When the sealing ring 34 reaches the position of the exhaust port 36, the airflow will be discharged, the air pressure will drop sharply, and the first spring 35 will extend to push the piston 33 back.

[0031] In a preferred embodiment, the quick-release assembly 4 includes an inner retaining ring 41, a second spring 42, a hollow groove 43, an arc-shaped locking block 44, and an outer ring 45. The second spring 42 is installed at the edge of the inner retaining ring 41, and the hollow groove 43 is formed through the outer wall of the inner retaining ring 41. The arc-shaped locking block 44 is slidably installed inside the hollow groove 43. The outer ring 45 is fitted onto the outer side of the inner retaining ring 41. Pulling the outer ring 45 away from the rust removal assembly 5... On one side, the second spring 42 is contracted, allowing the protruding part on the outer ring 45 to avoid the arc-shaped locking block 44. At this time, the mounting block 51 is installed into the inner fixing ring 41. The mounting block 51 will press the six sets of arc-shaped locking blocks 44 outward, thus entering between the inner fixing rings 41. At this time, the outer ring 45 is released, and the six sets of arc-shaped locking blocks 44 abut against the embedded groove 52 opened on the outer wall of the mounting block 51. The protruding part on the outer ring 45 restricts the position of the six sets of arc-shaped locking blocks 44, thus completing the fixation of the rust removal component 5.

[0032] In a preferred embodiment, the rust removal component 5 includes a mounting block 51, an inner groove 52, a hollow chamber 53, a pneumatic needle 54, a first convex ring 55, a second convex ring 56, a third convex ring 57, and a third spring 58. The outer wall of the mounting block 51 has an inner groove 52, and the interior of the mounting block 51 has a hollow chamber 53. The pneumatic needle 54 is installed through the inner side of the hollow chamber 53. The outer diameter surface of the pneumatic needle 54 is fixed with the first convex ring 55, and the second convex ring 56 is slidably disposed on one side of the first convex ring 55. The third convex ring 57 is fixed on the side of the second convex ring 56 away from the first convex ring 55, and the third spring 58 is fixed at the edge of the third convex ring 57.

[0033] The working process of this utility model is as follows: When in use, connect the air pump's air pipe to the air inlet 11, and then install the appropriate model of rust removal component 5 on the quick-release component 4 according to actual needs. By pulling the outer ring 45 away from the side of the rust removal component 5, the second spring 42 is contracted, allowing the protruding position on the outer ring 45 to avoid the arc-shaped locking block 44. At this time, the mounting block 51 is installed into the inner fixing ring 41. The mounting block 51 will press the six sets of arc-shaped locking blocks 44 outward, thereby entering between the inner fixing rings 41. At this time, the outer ring 45 is released, and the six sets of arc-shaped locking blocks 44 abut against the embedded groove 52 opened on the outer wall of the mounting block 51. The protruding position on the outer ring 45 restricts the position of the six sets of arc-shaped locking blocks 44, thus completing the fixation of the rust removal component 5.

[0034] During rust removal, multiple sets of pneumatic needles 54 are pressed against the rust spots. The air pump is started to pump air into the equipment. The airflow enters from the air inlet 11, enters the inside of the cylindrical handle 12, and then enters the metal shell 13. The air pressure then pushes the piston 33, causing the first spring 35 to contract. This causes the piston 33 to move, pushing the third convex ring 57 of the multiple sets of pneumatic needles 54, causing the third spring 58 to contract. The pneumatic needles 54 move forward. When the sealing ring 34 on the piston 33 reaches the position of the exhaust port 36 opened on the outer wall of the cylindrical shell 32, the internal gas is quickly discharged. The first spring 35 and the third spring 36... The three springs 58 will quickly extend, causing the piston 33 to retract and the multiple sets of pneumatic needles 54 to retract, completing one reciprocating motion. Then, by controlling the airflow, multiple reciprocating motions can be completed, and the pneumatic needles 54 will be vibrated quickly to complete the rust removal work. When the equipment is running, the vibration effect will be transmitted from the equipment body to the handle position. At this time, the metal ring 24 sleeved on the fixed shaft 23 fixed in the cylindrical groove 22 will absorb part of the vibration potential energy. In addition, the handle is also covered with a soft material to achieve the vibration reduction effect. The above is the working principle of this pneumatic needle rust removal equipment.
