[0012] Compared with the prior art, the present invention provides a new type of anti-rust cap, which has the following beneficial effects: 1. For this new type of anti-rust cap, by placing an anti-rust adsorption material at the bottom of the sealing cavity of the protective cap to make an anti-rust adsorption sealing plug, and then successively installing the upset end of the brake pipe and the connector into the protective cap, in this way, the problem that the upset end of the brake pipe rusts when encountering water vapor in the air can be well solved through these two methods of anti-rust oil and the sealing cavity.

[0013] 2. For this new type of anti-rust cap, when installing the protection cap, the internal air can be discharged through the exhaust pipe, thus avoiding the situation where the protection cap cannot be installed due to the inability to discharge the internal air.

[0014] 3. For this new type of anti-rust cap, the sealing plate a can seal the short pipe a. When installing the protection cap, the internal air is discharged through the exhaust pipe. The discharged air will push the sealing plate a to move to the right and then discharge the air.

[0015] 4. For this new type of anti-rust cap, first move the moving pipe to the left, then block the air groove and move the moving pipe to the right. In this way, negative pressure will be generated inside the moving pipe, which will drive the sealing plate a to move to the right and then suck out the air inside the sealing cap. In this way, the sealing ring can further fit with the sealing head for sealing.

[0016] 5. For this new type of anti-rust cap, when the internal air is squeezed by the two left moving pipes, it will drive the sealing plate b to move to the right, and then discharge the air inside the moving pipe. When the moving pipe is moved to the right again, the rebound of the pressure spring b will drive the sealing plate a to seal the short pipe b, so that negative pressure can be generated to suck out the air inside the protection cap.

[0017] 6. For this new type of anti-rust cap, the shielding pipe and the filter plate can protect mechanisms such as the sealing plate b from being scratched by external objects. The magnet can adsorb the metal ring when it approaches. Although it is laborious to move the moving pipe to the right due to the adsorption force, it can effectively fix the moving pipe to prevent it from shaking back and forth for effective use.

[0018] 7. For this new type of anti-rust cap, by moving the rotating ring to the right, the protection cap can be rotated back and forth through the movable column. After the protection cap is rotated and installed, the rotating ring can be moved to the left to drive the limiting rod to move to the left and insert into the corresponding circular groove, so as to prevent the rotating cap from rotating and falling off.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Example 1, please refer to Figures 1 - 2, the present invention provides a technical solution: a new type of anti-rust cap, which includes an end upset head 1. A sealing head 14 is provided at the right end of the end upset head 1. A connecting head 2 is sleeved on the end upset head 1. A threaded groove 27 is provided on the connecting head 2. A protective cap 6 is threadedly sleeved on the threaded groove 27. A sealing cavity 28 is provided inside the protective cap 6. An anti-rust adsorption sealing plug 15 is installed in the sealing cavity 28. The sealing head 14 is arranged in the sealing cavity 28 and is in contact with the anti-rust adsorption sealing plug 15. The anti-rust adsorption sealing plug 15 is made of anti-rust adsorption material. By placing the anti-rust adsorption sealing plug 15 made of anti-rust adsorption material at the bottom of the sealing cavity 28 of the protective cap 6, and then successively installing the end upset head 1 of the brake pipe and the connecting head 2 into the protective cap 6, in this way, the situation that the end upset head 1 of the brake pipe rusts when encountering water vapor in the air can be well solved through these two methods of anti-rust oil and the sealing cavity 28; Example 2, please refer to Figures 3 - 7, on the basis of the first embodiment, an exhaust pipe 16 is fixedly penetrated on the rust-proof adsorption sealing plug 15. The exhaust pipe 16 is fixedly penetrated through the protective cap 6. A sealing ring 41 is fixedly installed inside the protective cap 6. The sealing ring 41 is attached to the left side of the sealing head 14. Through the exhaust pipe 16, the internal air can be discharged when the protective cap 6 is installed, thus avoiding the situation that the protective cap 6 cannot be installed due to the inability to discharge the internal air. A short pipe a20 is fixedly installed on the right side of the protective cap 6. A blocking ring a33 is fixedly installed inside the short pipe a20. A short rod a32 is movably connected inside the blocking ring a33. A circular plate a34 is fixedly installed on the left side of the short rod a32. A pressure spring a30 is fixedly installed on the right side of the circular plate a34. The left and right ends of the pressure spring a30 are fixedly connected to the circular plate a34 and the blocking ring a33 respectively. A sealing plate a31 is fixedly installed at the right end of the short rod a32. The sealing plate a31 is attached to the right side of the short pipe a20. Two arc-shaped plates a29 are attached to the circular plate a34. Both arc-shaped plates a29 are fixedly connected to the blocking ring a33. The sealing plate a31 can seal the short pipe a20. When the protective cap 6 is installed, the internal air is discharged through the exhaust pipe 16. In this way, the discharged air will push the sealing plate a31 to move to the right and then discharge the air. When the air is discharged, the rebound of the pressure spring a30 will drive the sealing plate a31 to fit with the blocking ring a33 for sealing to prevent external water vapor and the like from entering the protective cap 6. A moving pipe 4 is movably sleeved on the protective cap 6. An annular wall groove 21 is formed on the inner side wall of the moving pipe 4.

A baffle 5 is fixedly installed at the right end of the moving pipe 4. An air groove 17 is formed on the baffle 5. By first moving the moving pipe 4 to the left and then blocking the air groove 17 and moving the moving pipe 4 to the right, a negative pressure will be generated inside the moving pipe 4, thereby driving the sealing plate a31 to move to the right and then the air inside the sealing cap 6 can be sucked out. In this way, the sealing ring 41 can be further attached to the sealing head 14 for sealing. A short pipe b42 is fixedly installed inside the air groove 17. A blocking ring b39 is fixedly installed inside the short pipe b42. A short rod b38 is movably connected inside the blocking ring b39. A circular plate b40 is fixedly installed on the left side of the short rod b38. A pressure spring b36 is fixedly installed on the right side of the circular plate b40.

A sealing plate b37 is fixedly installed at the right end of the short rod b38. The sealing plate b37 is attached to the right side of the short pipe b42. Two arc-shaped plates b35 are attached to the circular plate b40. Both arc-shaped plates b35 are fixedly connected to the blocking ring b39. By moving the moving pipe 4 to the left twice, the internal air is squeezed and will drive the sealing plate b37 to move to the right, and then the air inside the moving pipe 4 is discharged. In this way, when the moving pipe 4 is moved to the right again, due to the rebound of the pressure spring b36, the sealing plate a31 seals the short pipe b42, and thus a negative pressure can be generated to suck out the air inside the protective cap 6. A shielding pipe 19 is movably sleeved on the short pipe b42. The shielding pipe 19 is fixedly connected to the baffle 5.A filter plate 18 is fixedly installed inside the shielding tube 19. A metal ring 7 is fixedly installed on the left side of the moving tube 4. A fixing ring 25 is fixedly installed on the protective cap 6. A number of magnets 24 are inlaid on the right side of the fixing ring 25. A soft plate 23 is fixedly installed on the right side of each magnet 24. The shielding tube 19 and the filter plate 18 can protect mechanisms such as the sealing plate b37 from being scratched by external objects. When the metal ring 7 approaches, it can be adsorbed by the magnets 24. Although it is laborious to move the moving tube 4 to the right due to the adsorption force, it can effectively fix the moving tube 4 to avoid shaking back and forth for effective use. A rotating ring 8 is movably sleeved on the protective cap 6. A number of movable columns 9 are fixedly installed on the rotating ring 8. A number of limiting rods 10 are fixedly installed on the left side of the rotating ring 8. A small ring 11 is fixedly sleeved on each limiting rod 10. An annular block 26 is movably sleeved on a number of limiting rods 10. The annular block 26 is fixedly connected to the protective cap 6. A circular ring 12 is fixedly sleeved on the connector 2. A number of circular grooves 13 are formed on the circular ring 12. Each limiting rod 10 is respectively movably connected to each circular ring 12. By moving the rotating ring 8 to the right, the protective cap 6 can be rotated back and forth through the movable columns 9. After the protective cap 6 is rotatably installed, the rotating ring 8 can be moved to the left to drive the limiting rods 10 to move to the left and insert into the corresponding circular grooves 13, thereby preventing the rotating cap 6 from rotating and falling off.

[0024] When in use, the first step: By placing an anti-rust adsorption seal plug 15 made of anti-rust adsorption material at the bottom of the sealing cavity 28 of the protective cap 6, and then successively installing the upset head 1 of the brake pipe end and the connector 2 into the protective cap 6, in this way, the problem that the upset head 1 of the brake pipe end rusts when encountering water vapor in the air can be well solved through these two methods of anti-rust oil and the sealing cavity 28.

[0025] The second step: Through the exhaust pipe 16, the internal air can be discharged when installing the protective cap 6, thereby avoiding the situation that the protective cap 6 cannot be installed due to the inability to discharge the internal air.

[0026] The third step: Through the sealing plate a31, the short pipe a20 can be sealed. When installing the protective cap 6, the internal air is discharged through the exhaust pipe 16. In this way, the discharged air will push the sealing plate a31 to move to the right and then discharge the air. After the air is discharged, the rebound of the pressure spring a30 will drive the sealing plate a31 to fit with the blocking ring a33 for sealing to prevent external water vapor and the like from entering the protective cap 6.

[0027] The fourth step: By first moving the moving tube 4 to the left, then blocking the air groove 17 and then moving the moving tube 4 to the right, a negative pressure will be generated inside the moving tube 4, thereby driving the sealing plate a31 to move to the right and then the air inside the sealing cap 6 can be sucked out. In this way, the sealing ring 41 can further fit with the sealing head 14 for sealing treatment.

[0028] Step 5: When the internal air is squeezed by the two left-moving moving pipes 4, the sealing plate b37 will be driven to move to the right, and then the air in the moving pipe 4 will be discharged. When the moving pipe 4 is moved to the right again, the sealing plate a31 will be driven by the rebound of the pressure spring b36 to seal the short pipe b42, so that negative pressure can be generated to suck out the air in the protective cap 6.

[0029] Step 6: The shielding pipe 19 and the filter plate 18 can protect mechanisms such as the sealing plate b37 from being scratched by external objects. When the metal ring 7 approaches, it can be adsorbed by the magnet 24. Although it is laborious to move the moving pipe 4 to the right due to the adsorption force, it can effectively fix the moving pipe 4 to avoid shaking back and forth for effective use.

[0030] Step 7: By moving the rotating ring 8 to the right, the protective cap 6 can be rotated back and forth through the movable column 9. After the protective cap 6 is rotated and installed, the rotating ring 8 can be moved to the left to drive the limiting rod 10 to move to the left and insert into the corresponding circular groove 13, so as to prevent the rotating cap 6 from rotating and falling off.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
