[0018] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The chrome-plated protective anti-oxidation coating device mainly coats a uniform and dense chromium layer on the metal surface through electrolysis or chemical methods. This chromium layer can isolate air and moisture, prevent the metal substrate from contacting with oxygen, and thus effectively prevent the occurrence of oxidation reactions. At the same time, the chromium layer itself has excellent corrosion resistance and wear resistance, which can further improve the service life of the metal. The chrome-plated layer itself has good antioxidant properties and can protect the base metal from oxidation corrosion in high temperature or corrosive environments. The chrome-plated layer can significantly improve the corrosion resistance of the base metal, especially in harsh environments such as humidity and salt spray.

[0020] See also Figures 1-4 As shown, this embodiment provides a chrome plating protective anti-oxidation coating device, including a chrome plating coating device body 1 and a connecting pipe 10, the end of the connecting pipe 10 is fixedly connected to a telescopic tube 11, and the end of the telescopic tube 11 is fixedly connected to a nozzle pipe 12. The chrome plating protective anti-oxidation coating device is not convenient to carry in some outdoor occasions to chrome-plate metal parts. The existing chrome plating spray can is not convenient to fix the metal parts when in use, and is easily exposed to human body due to environmental factors during operation, which has low safety. Therefore, the details are as follows: a clamping assembly 2 is provided on the outside of the chrome plating coating device body 1, and the clamping assembly 2 is used to clamp the metal parts for chrome plating. The clamping assembly 2 includes a bidirectional screw rod 23 and a clamping plate 24, wherein:

[0021] The clamping plates 24 move on the bidirectional screw rod 23 along its length direction. The two clamping plates 24 clamp the metal piece on the outside of the chrome coating device body 1, making it convenient for users to chrome-plate the metal piece.

[0022] The improvement of this embodiment is that:

[0023] Rotating the bidirectional screw rod 23 drives the two clamping plates 24 of the outer wall to move in opposite directions to clamp the placed metal parts. The two clamping plates 24 clamp the metal parts in the middle to fix the position of the metal parts to prevent them from being accidentally touched and falling, making it convenient for users to use the nozzle tube 12 to chrome-plate the metal parts.

[0024] The chrome plating device 20 is fixedly connected to the outside of the chrome plating device body 1, and the side plate 201 is fixedly connected to the outside of the base 20. The side plate 201 is fixedly connected to the placement plate 21. Two mounting plates 22 are provided above the placement plate 21, and a two-way screw rod 23 is rotatably connected between the two mounting plates 22. The outer wall of the two-way screw rod 23 is symmetrically rotatably connected to two clamping plates 24. Two clamping plates 24 are fixedly connected to two sliding blocks 241 on both sides. Two sliding grooves 211 are symmetrically provided above the placement plate 21. The outer walls of the two sliding blocks 241 slide and adapt to the inner walls of the two sliding grooves 211 respectively. A handle is provided above the side plate 201, and holding the handle makes it convenient for the user to carry the chrome plating device body 1. The two-way screw rod 23 rotates between the two mounting plates 22. When the two-way screw rod 23 rotates, it drives the two clamping plates 24 of the outer wall to move in opposite directions, driving the two sliding blocks 241 to slide on the inner walls of the sliding grooves 211, and the two clamping plates 24 clamp the metal parts in the middle.

[0025] Considering that it is inconvenient for users to rotate the bidirectional screw rod 23, a first motor 25 is fixedly installed on the outside of the mounting plate 22. The end of the first motor 25 extends into the inner wall of the mounting plate 22, and the output shaft is fixedly connected to the end of the bidirectional screw rod 23. The output shaft at the end of the first motor 25 drives the bidirectional screw rod 23 to rotate between the two mounting plates 22.

[0026] Considering that both sides of the metal part need to be chrome-plated, two fixed plates 26 are fixedly connected above the placement plate 21, and a rotating rod 261 is rotatably connected between the two fixed plates 26. The inner walls of the two mounting plates 22 are fixedly sleeved on the outer walls of the rotating rod 261, and a second motor 27 is fixedly installed on the outside of the fixed plate 26. The end of the second motor 27 extends into the inner wall of the fixed plate 26, and the output shaft is fixedly connected to the end of the rotating rod 261. Turn on the second motor 27, and the output shaft at the end of the second motor 27 drives the rotating rod 261 to rotate between the two fixed plates 26. The rotating rod 261 drives the clamping assembly 2 to rotate as a whole. After the clamping assembly 2 is flipped 180° as a whole, the second motor 27 is turned off and the back of the metal part is chrome-plated.

[0027] Taking into account that the nozzle tube 12 is easily affected by the flowing air during chrome plating and splashes onto the human body, a threaded tube 28 is fixedly sleeved on the outer wall of the nozzle tube 12, and a mounting tube 29 is threadedly connected to the outer wall of the threaded tube 28. A protective cover 291 is fixedly connected to the end of the mounting tube 29. The protective cover 291 is in the shape of a "cone". Hold the outer wall of the mounting tube 29, align the opening of the mounting tube 29 with the end of the nozzle tube 12, and put the mounting tube 29 on the outside of the nozzle tube 12. Align the end of the mounting tube 29 with the end of the threaded tube 28 and rotate it. The mounting tube 29 rotates on the outer wall of the threaded tube 28, and install the protective cover 291 on the outside of the nozzle tube 12. Open the main body 1 of the chrome plating coating device. The protective cover 291 blocks the outside and rear of the nozzle tube 12 to prevent the chromium solution from contacting the operator and improve safety.

[0028] In summary, the working principle of this solution is as follows:

[0029] When the chrome-plated protective anti-oxidation coating device of the present invention is used, a handle is provided above the side panel 201, and the user can carry the chrome-plated coating device body 1 by holding the handle. The metal part is placed above the placement plate 21 and the first motor 25 is turned on. The output shaft at the end of the first motor 25 drives the bidirectional screw 23 to rotate between the two mounting plates 22. When the bidirectional screw 23 rotates, the two clamping plates 24 on the outer wall move in opposite directions, driving the two sliding blocks 241 to slide on the inner wall of the sliding groove 211. After the two clamping plates 24 clamp the metal part in the middle, the first motor 25 is turned off, the outer wall of the mounting tube 29 is held, the opening of the mounting tube 29 is aligned with the end of the nozzle tube 12, the mounting tube 29 is put on the outside of the nozzle tube 12, the end of the mounting tube 29 is aligned with the end of the threaded tube 28 and rotated, the mounting tube 29 rotates on the outer wall of the threaded tube 28, and the protective cover 291 is installed on the nozzle tube 12. Externally, open the chrome plating coating device body 1, and the chromium solution inside the chrome plating coating device body 1 flows along the connecting pipe 10 to the nozzle pipe 12. Pull the telescopic tube 11 to adjust the spray distance of the nozzle pipe 12. When the nozzle pipe 12 chrome-plates the metal parts, the liquid sprayed out will be affected by the flowing air and spread around. The protective cover 291 blocks the outside and the rear of the nozzle pipe 12 to prevent the chrome solution from contacting the operator, thereby improving safety. After the chrome plating of one side of the metal part is completed, turn on the second motor 27. The output shaft at the end of the second motor 27 drives the rotating rod 261 to rotate between the two fixed plates 26. The rotating rod 261 drives the clamping assembly 2 to rotate as a whole. After the clamping assembly 2 is flipped 180° as a whole, turn off the second motor 27, chrome-plate the back of the metal part, wait for the chrome solution to dry, turn on the first motor 25 to release the clamping of the metal part.
