[0018] A new type of circular oil level indicator, such as Figure 1 and Figure 3 As shown, the device includes a cylindrical shell 1, which is horizontally axially positioned. One end of the outer wall of the shell 1 is a threaded fixed end, and the other end face of the shell 1 is provided with an observation window 10. An observation mark is provided inside the shell 1. The observation window 10 includes an annular boss 5 integrally formed at the port of the inner wall of the shell 1 and a transparent sheet 4 sleeved at the port. The annular boss 5 stops at the outer edge of the transparent sheet 4. A U-shaped groove 2 is threaded into the shell 1, and the inner end face of the U-shaped groove 2 abuts against the inner edge of the transparent sheet 4. An observation cavity is formed between the groove of the U-shaped groove 2 and the transparent sheet 4. A float 3 is provided in the observation cavity, which serves as the observation mark. The two sides of the float 3 are close to the transparent sheet 4 and the bottom surface of the U-shaped groove 2, respectively. To facilitate the observation and confirmation of the position of the float 3, the float 3 is preferably red. Through holes 21 for communicating with the observation cavity are distributed on the bottom wall of the U-shaped groove 2 to facilitate the entry of liquid into the observation cavity. Figure 2 As shown, through holes 21 are evenly distributed on the bottom wall of the U-shaped trough 2.

[0019] Among them, such as Figure 3 As shown, to facilitate sealing the gap between the transparent sheet 4 and the housing 1, a first annular groove 51 is provided on the annular boss 5 at the position between it and the transparent sheet 4. A first sealing ring 52 is embedded in the first annular groove 51. The transparent sheet 4 presses against the first sealing ring 52, causing the first sealing ring 52 to be sealed between the transparent sheet 4 and the bottom surface of the first annular groove 51, thereby preventing liquid from flowing out of the housing 1 through the gap between the transparent sheet 4 and the housing 1; to seal the gap between the side of the transparent sheet 4 and the inner wall of the housing 1, such as Figure 4 As shown, a second annular boss 22 is provided on the inner edge of the inner end face of the U-shaped groove 2. The platform of the second annular boss 22 is an outer arc surface. The second annular boss 22 and the outer sidewall of the U-shaped groove 2 are connected by an annular inclined surface 23.

A second sealing ring 6 is provided in the annular placement groove. The annular inclined surface 23 and the second sealing ring 6 are pressed and adhered together, and the other sides of the second sealing ring 6 are respectively adhered to the transparent sheet 4 and the inner wall of the shell 1, so that the second sealing ring 6 forms a sealing structure between the annular inclined surface 23, the transparent sheet 4 and the inner wall of the shell 1.

[0020] In addition, combined Figure 2 and Figure 3As shown, to facilitate the fixed connection of the housing 1 to the side wall of the hydraulic oil tank, a threaded section 13 is provided on the outer wall of the fixed end of the housing 1, and a limit ring 12 is integrally provided on the outer wall of the observation end of the housing 1. A second annular groove 121 is provided on the inner end face of the limit ring 12. The second annular groove 121 is used to embed an annular sealing gasket. The groove opening of the second annular groove 121 faces downwards towards the threaded section 13. To facilitate the screwing of the housing 1, an annular locking platform 11 for locking a wrench is integrally provided on the outer end face of the limit ring 12. The outer ring of the annular locking platform 11 is hexagonal or quadrangular, and the inner ring of the annular locking platform 11 coincides with the observation window 10. Two oblong holes 111 are provided on the outer end section of the annular locking platform 11. The two oblong holes 111 are located on both sides of the observation window 10.

[0021] During installation, in conjunction with Figure 5 As shown, the housing 1 is threaded into the mounting hole on the side wall of the hydraulic oil tank 7, and the annular sealing gasket 71 provided in the second annular groove 121 is pressed and sealed between the limiting ring 12 and the side wall of the hydraulic oil tank 7. During operation, when the liquid level is higher than the through hole 21, the liquid in the hydraulic oil tank 7 enters and exits the observation chamber through the through hole 21, and the float 3 floats up and down near the transparent plate 4. The change in the position of the float 3 can be observed through the observation window 10, thereby understanding the liquid level position in the hydraulic oil tank 7.
