A spring 7 is fixedly connected between the connecting block 22 and the top inside the connector 1. A limit slider 23 is fixedly connected to the side of the connecting block 22 near the outside. Limit grooves 11 are provided at the front and rear ends of the left and right sides inside the connector 1.

[0028] The limiting slider 23 is set inside the limiting slide groove 11. The limiting slider 23 slides up and down inside the limiting slide groove 11. The movable cover 3 is set at the bottom outside the connector 1. The movable cover 3 slides outside the connector 1. A reserved groove 18 is opened at the top right side inside the movable cover 3. The reserved groove 18 and the left side of the connecting line 12 cooperate with each other.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the movable cover 3 and the waterproof sleeve 5 can shield the connector 1 and the plug 2, thus protecting them. When using this power cord, the plug 2 needs to be inserted into the hole of the socket. When the plug 2 is inserted, the movable cover 3 will rise by squeezing the spring 7 through the connecting block 22. After the plug 2 is inserted, the spring 7 will press the movable cover 3 against the surface of the socket through its own elasticity, sealing the socket and the movable cover 3. This can prevent external water from entering the interior of the movable cover 3 and affecting the use of the connector 1 and the plug 2. The sealing gasket 4 can further improve the sealing between the movable cover 3 and the socket.

[0030] The top of the top cover 6 is fixedly connected to a threaded sleeve 10, and the top of the waterproof sleeve 5 is fixedly connected to a fixing block 19. The fixing block 19 has a second threaded groove 21 inside, and the threaded sleeve 10 has a first threaded groove 20 inside. The second threaded groove 21 and the first threaded groove 20 are provided with threaded rods 9 inside. The top of the threaded rod 9 is fixedly connected to a rotating plate 8. The threaded rod 9 cooperates with the second threaded groove 21 and the first threaded groove 20 respectively. The threaded rod 9 rotates inside the threaded sleeve 10 through the thread.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, when it is necessary to fix the connector 1, the bottom end of the threaded rod 9 is placed inside the threaded sleeve 10, and then the connector 1 is fixed by rotating the rotating plate 8. The rotating plate 8 can drive the threaded rod 9 to rotate inside the threaded sleeve 10 and the second threaded groove 21. Since the threaded rod 9 is engaged with the second threaded groove 21 and the first threaded groove 20 respectively, and the fixing block 19 outside the second threaded groove 21 is fixed to the top of the waterproof sleeve 5, the rotation of the threaded rod 9 can make the bottom end of the threaded rod 9 embedded inside the threaded sleeve 10, thereby fixing the connector 1 inside the waterproof sleeve 5.

[0032] A fixing sleeve 17 is provided on the left side of the outside of the connecting line 12. The two ends of the top of the fixing sleeve 17 are fixedly connected to the limiting plate 13. The front and rear ends of the limiting plate 13 are fixedly connected to the limiting block 15. A binding elastic band 16 is wound around the outside of the fixing sleeve 17. A fixing hole 14 is opened at the top of the inside of the binding elastic band 16. The top of the binding elastic band 16 is set outside the limiting plate 13 through the fixing hole 14. The limiting block 15 limits the binding elastic band 16 through the fixing hole 14. The binding elastic band 16 is wound around the outside of the connecting line 12. A corrosion-resistant coating 24 is provided on the outside of the connecting line 12. A waterproof membrane 25 is provided on the outside of the corrosion-resistant coating 24.

[0033] Specifically, such as Figure 1 and Figure 5 As shown, when packaging and transporting the power cord or when the power cord is long, the excess connecting wire 12 is folded up, and then the elastic strap 16 is wrapped around the outside of the connecting wire 12. After wrapping, the top of the elastic strap 16 is put over the outside of the limiting plate 13 through the fixing hole 14. The limiting blocks 15 at the front and rear ends of the limiting plate 13 can limit the elastic strap 16, thereby fixing the elastic strap 16 and preventing the connecting wire 12 from becoming loose due to accidental loosening of the elastic strap 16. Folding and limiting the connecting wire 12 can prevent the connecting wire 12 from becoming tangled together. The corrosion-resistant coating 24 and the waterproof membrane 25 can protect the connecting wire 12.

[0034] Working Principle: In use, the bottom end of the threaded rod 9 is placed inside the threaded sleeve 10. Then, the fixed connector 1 is rotated by rotating the rotating plate 8. The rotating plate 8 drives the threaded rod 9 to rotate inside the threaded sleeve 10 and the second threaded groove 21. Since the threaded rod 9 cooperates with both the second threaded groove 21 and the first threaded groove 20, and the fixing block 19 outside the second threaded groove 21 is fixed to the top of the waterproof sleeve 5, the rotation of the threaded rod 9 allows its bottom end to be embedded inside the threaded sleeve 10, thus fixing the connector 1 inside the waterproof sleeve 5. The movable cover 3 and the waterproof sleeve 5 can shield the connector 1 and the plug 2, thus protecting them. When using this power cord, the plug 2 needs to be inserted into the hole of the socket plate. When the plug 2 is inserted, the movable cover 3 will rise by squeezing the spring 7 through the connecting block 22. After the plug 2 is inserted, the spring 7 will use its elasticity to press the movable cover 3 against the surface of the socket plate, sealing the socket plate and the movable cover 3, thereby preventing external... Water entering the interior of the movable cover 3 affects the use of connector 1 and plug 2. The sealing gasket 4 can further improve the sealing between the movable cover 3 and the plug plate. The limiting slider 23 will slide up and down inside the limiting groove 11, thereby improving the stability of the movable cover 3 lifting and lowering. When packaging and transporting the power cord or when the power cord is long, fold up the excess connecting wire 12, and then wrap the elastic strap 16 around the outside of the connecting wire 12. After wrapping, put the top of the elastic strap 16 on the outside of the limiting plate 13 through the fixing hole 14. The limiting blocks 15 at the front and rear ends of the limiting plate 13 can limit the elastic strap 16, thereby fixing the elastic strap 16 and preventing the elastic strap 16 from accidentally loosening and causing the connecting wire 12 to loosen. Folding and limiting the connecting wire 12 can prevent the connecting wire 12 from being scattered and tangled together. The corrosion-resistant coating 24 can increase the corrosion resistance of the surface of the connecting wire 12, and the waterproof membrane 25 can prevent water from seeping into the interior of the connecting wire 12 and affecting the connecting wire 12.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
