The pressing assembly 200 is arranged on the base assembly 100. The bearing surface of the bolt 210 of this sealing device rotates following the one-way thrust ball bearing 270, without direct dry friction with the sealing plate 110, will not drop powder, and effectively eliminates the hidden danger of cleanliness.

[0033] Please refer to Figure 1 , Figure 2 and Figure 4 , the base assembly 100 includes a sealing plate 110. The base assembly 100 further includes a handle 120, and the handle 120 is fixed on the outer wall of the sealing plate 110. The handle 120 facilitates the lifting of this sealing device. The base assembly 100 further includes a first hexagon socket head cap screw 130, and the handle 120 is fixed on the sealing plate 110 through the first hexagon socket head cap screw 130. The first hexagon socket head cap screw 130 facilitates the installation and fixation of the handle 120 on the sealing plate 110.

[0034] Please refer to Figure 1 , Figure 3 and Figures 5-9, the pressing assembly 200 includes a bolt 210, a pressing seat 220, a gasket 250, a pressing sleeve 260, a single-direction thrust ball bearing 270 and a small round nut 280. The pressing seat 220 is fixed on the sealing plate 110. There are multiple pressing seats 220, and they are evenly distributed on the sealing plate 110. The multiple pressing seats 220 fix the sealing plate 110 more firmly on the cylinder block. The pressing assembly 200 further includes a second hexagon socket head cap screw 230. The pressing seat 220 is fixed on the sealing plate 110 by the second hexagon socket head cap screw 230. The second hexagon socket head cap screw 230 facilitates the installation and fixation of the pressing seat 220 on the sealing plate 110. A third through hole 291 is formed in the pressing seat 220, and the second hexagon socket head cap screw 230 passes through the third through hole 291. The third through hole 291 facilitates the second hexagon socket head cap screw 230 to pass through the pressing seat 220. The small round nut 280 is welded inside the pressing seat 220. The single-direction thrust ball bearing 270 is inserted into the pressing seat 220. The pressing sleeve 260 is inserted into the single-direction thrust ball bearing 270. The bolt 210 is inserted into the pressing sleeve 260. The bolt 210 also threadedly penetrates the small round nut 280. A first through hole 140 is formed in the sealing plate 110, and the bolt 210 passes through the first through hole 140. The first through hole 140 facilitates the bolt 210 to pass through the sealing plate 110. The gasket 250 is fixed on the sealing plate 110. The gasket 250 includes a gasket body 251 and a hexagon socket countersunk head screw 252. The gasket body 251 is fixed on the sealing plate 110 by the hexagon socket countersunk head screw 252. The hexagon socket countersunk head screw 252 facilitates the installation and fixation of the gasket body 251 on the sealing plate 110. A second through hole 290 is formed in the gasket 250, and the second through hole 290 is arranged corresponding to the first through hole 140. The second through hole 290 facilitates the bolt 210 to pass through the gasket 250. The area of the sealing plate 110 is less than or equal to the area of the gasket 250, and the thickness of the sealing plate 110 is greater than the thickness of the gasket 250. The gasket 250 makes the sealing between the sealing plate 110 and the cylinder block better.

[0035] Specifically, the working principle of the cylinder block leak detection and sealing device is as follows: When in use, before assembly, clean the sealing plate 110, the first hexagon socket head cap screw 130, the bolt 210, the pressing seat 220, the gasket 250, the pressing sleeve 260, the single-direction thrust ball bearing 270, and the small round nut 280. Apply lubricating oil to the bolt 210, the pressing sleeve 260, and the single-direction thrust ball bearing 270. Install and fix the gasket 250 on the sealing plate 110, install and fix the pressing seat 220 on the sealing plate 110. Then, insert the single-direction thrust ball bearing 270 with the side having a gap facing the pressing seat 220 into it. Next, insert the pressing sleeve 260 into the single-direction thrust ball bearing 270. Finally, insert the bolt 210 into the pressing sleeve 260 and rotate the bolt 210 to screw it into the cylinder block. The bearing surface of the bolt 210 of this sealing device rotates following the single-direction thrust ball bearing 270, without direct dry friction with the sealing plate 110, and no powder will fall off, effectively eliminating the hidden danger of cleanliness.
