[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figs. 1 to 3 As shown, this utility model provides a valve body internal quantitative grease application structure, including a workbench 1, with fixed bending pieces 11 fixedly connected to the front and rear sides of the upper end of the workbench 1, and a cylinder structure 2 fixedly connected to one side of the fixed bending pieces 11 close to each other. The front end of the cylinder structure 2 is provided with a grease chamber block 21, the rear end of the grease chamber block 21 is connected to the cylinder body 22, the rear end of the cylinder body 22 is fixedly connected to an air inlet block 23, and the rear end center position of the air inlet block 23 is movably connected to a telescopic rod 24.

[0025] The grease chamber block 21 has a coating column 3 at the center of its front end. The coating column 3 is hollow inside and has coating holes 31 evenly distributed on its surface.

[0026] Furthermore, a grease cavity 211 is provided at the center of the grease chamber block 21. The grease cavity 211 is cylindrical, and an oil injection channel is provided on the upper side of the grease cavity 211. A sealing rubber gasket 212 is provided at the upper end of the oil injection channel. When the sealing rubber gasket 212 is opened, the oil injection channel is exposed. An external oil injection pipe can be connected to the oil injection channel to inject grease into the grease cavity 211. After the grease is filled, the sealing rubber gasket 212 can be sealed to the upper hole of the oil injection channel, making the grease cavity 211 a sealed chamber, which facilitates the cylinder to push the grease out of the grease cavity 211.

[0027] Furthermore, a compression plate 213 is provided at the rear end of the grease cavity 211, and a sealing sliding plate 241 of the same size is provided at the rear end of the compression plate 213. A telescopic rod 24 is fixedly connected to the center of the rear end of the sealing sliding plate 241. The compression plate 213 is a thin rubber sheet. The compression plate 213 is used to seal the grease cavity 211 to prevent grease inside the grease cavity 211 from flowing into the cylinder body 22 and affecting the movement of the entire cylinder. Then, the sealing sliding plate 241 can press the internal air pressure onto the compression plate 213, causing the compression plate 213 to deform, thereby squeezing the grease cavity 211 and causing the grease to be extruded from the coating hole 31. The principle is simple and the cost is low.

[0028] Furthermore, the upper end of the air intake block 23 is provided with an air intake hole 231, and the upper end of the grease chamber block 21 is provided with a second air hole 214. The lower end of the second air hole 214 is provided with an air outlet channel, which connects to the cylinder body 22. The air intake hole 231 allows air to enter the air intake block 23. The piston inside the air intake block 23 pushes the telescopic rod forward, thereby causing the sealing sliding plate 241 to move forward and squeeze out the grease. Then, the gas enters from the second air hole 214 and exits from the air intake hole 231, and the telescopic rod 24 returns to its normal position. During the resetting process, grease is also squeezed out, allowing workers to apply it to the inner wall of the valve body, which is simple and efficient.

[0029] Furthermore, the air outlet channel is connected to the front end of the sealing sliding plate 241, which facilitates the reset of the telescopic rod 24, facilitates cyclic operation, and improves efficiency.

[0030] Furthermore, the coating column 3 has a cylindrical hollow channel inside, and the coating holes 31 are symmetrically arranged on the left and right sides, which facilitates the precipitation of grease and facilitates the contact between the coating column 3 and the inner wall of the valve body. Then, the worker rotates the column to evenly coat the inner wall with the precipitated grease, which is simple and efficient.

[0031] Working process: first, the oil cavity 211 is filled with oil, the sealing rubber pad 212 is opened, the external oil inlet pipe is connected with the oil cavity 211, the sealing rubber pad 212 is covered after filling, then the cylinder structure 2 starts to work, the air inlet block 23 inhales air, the gas in the air inlet channel pushes the telescopic rod to move to the front end, so that the sealing sliding sheet 241 is pushed to the front end, then the extrusion sheet 213 extrudes the oil cavity 211 to the front end, so that the oil can be separated from the coating hole 31 of the coating column 3, the worker needs to sleeve the valve body and the coating column 3, then rotates the valve body to realize uniform coating of the inner wall of the valve body, which is simple and efficient, the whole structure occupies small space, the structure is simple, and the oil coating is convenient and fast.
