Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description:
referring to fig. 1-6, the water drill sealing structure comprises a power tool shell 1, wherein the power tool shell 1 comprises a framework oil seal 5, a sealing ring 6, a water seal 7 and a wool ring 8.
As shown in fig. 3 and 5, the skeleton oil seal 5 is disposed between the front end of the electric tool housing 1, the intermediate cover 12, and the output shaft 13.
In this embodiment, one of the frame oil seals 5 is disposed between the inner wall of the front end of the electric tool housing 1 and the output shaft 13 of the electric tool, and a gap is left between the frame oil seal 5 and the outer vertical surface of the front end of the electric tool housing 1, so that the frame oil seal 5 is disposed in a built-in manner, and damage to the frame oil seal 5 is prevented.
For the two framework oil seals arranged at different positions, in this embodiment, the framework oil seals each include a first portion attached to the corresponding first wall and a second portion attached to the corresponding second wall, and a gap is formed between the first portion and the second portion, that is, as shown in a cross-sectional view in the figure, a schematic cross-sectional view of a single side is in a U shape.
As shown in fig. 4, the sealing ring 6 is disposed between the head shell 14 and the middle cover 12, in this embodiment, in order to improve the sealing effect of the sealing ring 6, a mounting groove is formed in the head shell 14 and/or the middle cover 12, the sealing ring is tightly attached to the inner wall of the mounting groove, and after mounting, the outer wall of the sealing ring is attached to the corresponding wall of the head shell 14 and the wall of the middle cover 12.
As shown in fig. 5, the water seal 7 is disposed between the faucet assembly 15 and the output shaft 13, in this embodiment, the output shaft 13 is provided with an annular groove 131, the outer wall of the water seal 7 is abutted against the inner wall of the annular groove 131, the inner wall is abutted against the outer wall of the faucet assembly 15, the annular groove is provided on the output shaft 13, and the processing is more convenient, and the water channel pipe of the faucet assembly is not slotted, so that the smoothness of the water channel flow can be improved, namely, the sealing effect is enhanced on the premise of ensuring the overall performance.
As shown in fig. 6, the wool loop 8 is disposed between the rotor 16 and the inner wall of the electric tool housing 1, and specifically, the electric tool housing 1 includes a receiving groove in which the wool loop 8 is disposed.
Through the sealing member at different positions, adopt rather than the more adaptation to make the sealed cooperation effect between the two better, thereby can effectually promote sealed effect.
