[0021] See also Figure 1-Figure 5 The utility model discloses a charging pile cable fastening device, comprising a mounting seat 1, a charging cable 3 connected to one end of the mounting seat 1, and a connecting seat 2, the connecting seat 2 is fixed to one end of the mounting seat 1, and a slot 5 is provided on the connecting seat 2; it also comprises a fixing sleeve 4, the fixing sleeve 4 is installed at one end of the connecting seat 2, and a through hole adapted to the charging cable 3 is provided at one end of the fixing sleeve 4, a waterproof pad is provided between the through hole and the charging cable 3 to prevent water stains and dust from penetrating into the fixing sleeve 4 from the through hole, and the other end of the fixing sleeve 4 extends into the slot 5, thereby improving the sealing effect of the connection between the other end of the fixing sleeve 4 and the connecting seat 2, in addition, a second wedge block 10 is fixed at equal intervals in the fixing sleeve 4 away from one end of the connecting seat 2, and the second wedge block 10 is an inclined structure on the side opposite to the charging cable 3;

[0022] Furthermore, the charging pile cable fastening device provided in this embodiment also includes a fixing tube 7, which is fixed to one end of the connecting seat 2, and the fixing tube 7 is provided with through grooves 13 adapted to the second wedge block 10 at equal intervals, that is, the through grooves 13 on the same side are on the same straight line as the second wedge block 10, and a first wedge block 8 is slidably installed inside the through groove 13, and the first wedge block 8 is an inclined structure on the side opposite to the second wedge block 10, and one end of the first wedge block 8 is inserted into the fixing tube 7 and is installed with a U-shaped spring piece 9, which pushes the fixing sleeve 4 to move, and further makes the second wedge block 10 abut against the first wedge block 8, so that the first wedge block 8 drives the U-shaped spring piece 9, so that the U-shaped spring piece 9 is tightly abutted against the charging cable 3, thereby realizing the clamping of the charging cable 3. By setting the U-shaped spring piece 9, the stability of the charging cable 3 when clamped can be increased. In addition.

[0023] like Figure 4As shown, in order to improve the stability of the connection between the U-shaped spring piece 9 and the charging cable 3, a fixed sleeve 4 is passed through one end of the charging cable 3 and a rubber bushing 6 is installed. The rubber bushing 6 is glued to the charging cable 3, which can not only increase the outer diameter of the charging cable 3 to prevent the charging cable 3 from detaching from the through hole, but also increase the friction between the charging cable 3 and the U-shaped spring piece 9, thereby improving the stability of the U-shaped spring piece 9 when clamped. In order to further improve the stability of the charging cable 3 after installation, an anti-skid pad is installed on the side of the U-shaped spring piece 9 opposite to the charging cable 3, and the anti-skid pad is against the rubber bushing 6, thereby further improving the stability of the connection between the U-shaped spring piece 9 and the charging cable 3.

[0024] like Figure 2 and Figure 3 As shown, in order to facilitate the installation of the fixed sleeve 4, a guide groove 12 slidably connected to one end of the first wedge block 8 is opened on the inner wall of the fixed sleeve 4, which can prevent the fixed sleeve 4 from rotating and causing the clamping effect of the charging cable 3 to decrease, and can also achieve guidance during the installation of the fixed sleeve 4, so as to facilitate the installation of the fixed sleeve 4.

[0025] In addition, to prevent the first wedge block 8 from falling off from the through slot 13, one end of the first wedge block 8 passes through the through slot 13 and is installed with a limiting column. The setting of the limiting column can prevent the first wedge block 8 from slipping and improve the stability of the first wedge block 8 after installation.

[0026] like Figure 3 and Figure 5 As shown, in order to further improve the stability of the fixed sleeve 4 after installation, guide rails 14 are provided at equal intervals on the inner wall of the slot 5, and the guide rails 14 are slidably connected to the guide grooves 12. The sliding connection between the guide rails 14 and the guide grooves 12 facilitates the stable insertion of the fixed sleeve 4 into the slot 5.

[0027] like Figure 2 As shown, in order to improve the sealing of the connection between the charging cable 3 and the connecting seat 2, a sealing ring is installed at the end of the fixed sleeve 4 inserted into the slot 5, thereby improving the sealing of the connection between the fixed sleeve 4 and the slot 5, and a sealing gasket 11 is provided at the end of the fixed sleeve 4 away from the connecting seat 2, and the sealing gasket 11 is adapted to the fixed tube 7. Through the setting of the sealing gasket 11, the end of the fixed tube 7 away from the connecting seat 2 is sealed, thereby improving the sealing effect after the fixed sleeve 4 is installed.

[0028] like Figure 1 and Figure 2 As shown, in order to facilitate the stability of the fixed sleeve 4 after installation, a first bolt connecting plate is fixed at equal intervals on the outside of the fixed sleeve 4, and a second bolt connecting plate is fixed at equal intervals on the outside of the connecting seat 2. A fastening bolt is provided between the first bolt connecting plate and the relative second bolt connecting plate. The first bolt connecting plate and the relative second bolt connecting plate are connected by the fastening bolt, thereby achieving the fixation of the fixed sleeve 4.

[0029] The working principle and use process of the utility model are as follows: when in use, insert one end of the charging cable 3 into the fixed sleeve 4. At this time, the rubber bushing 6 is sleeved on the outside of the charging cable 3 and fixed by gluing, and the fixed sleeve 4 is pushed. The sliding connection between the first wedge block 8 and the guide groove 12 facilitates the movement of the fixed sleeve 4, and further makes the second wedge block 10 abut against the first wedge block 8, so that the first wedge block 8 drives the U-shaped spring piece 9, so that the U-shaped spring piece 9 is tightly abutted against the charging cable 3, thereby realizing the clamping of the charging cable 3, and continuing to push The movable fixing sleeve 4 allows one end of it to be inserted into the slot 5, and the sliding connection between the guide rail 14 and the guide groove 12 improves the stability of the fixing sleeve 4 when connected to the slot 5. At this time, the sealing gasket 11 abuts against one end of the fixing tube 7, thereby achieving the sealing of the port of the fixing tube 7, and then the first bolt connecting plate is connected to the opposite second bolt connecting plate by tightening bolts, thereby achieving the installation of the fixing sleeve 4, and then improving the sealing effect of the connection between the charging cable and the connecting seat 2 to avoid water stains and dust infiltration, thereby improving the stability of the charging cable when connected.
