[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Please refer to the appendix. Figures 1-5 The present invention provides a pneumatic lifting door, including a lifting door body 1 and a side mounting bracket 2, and also includes a pneumatic lifting assembly. The pneumatic lifting assembly is fixedly installed on the lifting door body 1. The pneumatic lifting assembly and the lifting door body 1 are slidably connected through a first guide rail assembly. The lifting door body 1 and the side mounting bracket 2 are slidably connected through a second guide rail assembly. A first guide rail care assembly is detachably installed on the first guide rail assembly, and a second guide rail care assembly is detachably installed on the second guide rail assembly.

[0026] The pneumatic lifting assembly includes a vertically arranged cylinder 3, which is fixedly installed on the side of the lifting door body 1 away from the side mounting bracket 2. A door panel connector 4 is fixed to the top of the output shaft of the cylinder 3. The door panel connector 4 is fixedly installed on the side of the lifting door body 1. Specifically, when the cylinder 3 is running, it can drive the lifting door body 1 to move up and down through the door panel connector 4, thereby effectively realizing the opening and closing of the lifting door body 1.

[0027] The first guide rail assembly includes a vertically arranged first guide rail 5, which is fixed to the side of the lifting door body 1 near the cylinder 3. A cylinder connector 6 is fixed to the top of the cylinder 3, and a first sliding block 7 is fixed to the surface of the cylinder connector 6. The first sliding block 7 slides on the surface of the first guide rail 5. Specifically, when the cylinder 3 operates and drives the lifting door body 1 to move up and down, the first guide rail 5 on the lifting door body 1 slides relative to the first sliding block 7 on the cylinder connector 6.

[0028] The second guide rail assembly includes a vertically arranged second guide rail 8, which is fixed to the surface of the side mounting bracket 2. A right-angle connector 9 is fixed to one end of the lifting door body 1 near the side mounting bracket 2. A second sliding block 10 is fixed to the surface of the right-angle connector 9. The second sliding block 10 slides on the surface of the second guide rail 8. Specifically, when the cylinder 3 operates to drive the lifting door body 1 to move up and down, the second sliding block 10 can also slide synchronously on the surface of the second guide rail 8. That is, the pneumatic lifting door uses a combination of linear guide rail and cylinder to achieve stable lifting of the lifting door body 1, ensuring the stability and accuracy of the lifting door during the movement process, reducing noise, reducing wear parts, extending the service life of the lifting door, and making it easy to operate and highly safe.

[0029] The first guide rail care assembly includes a first connecting plate 11 and a first connecting piece 12. The upper and lower ends of the first connecting piece 12 are respectively fixed to the bottom end of the cylinder connector 6 and the top end of the first connecting plate 11 by first fixing screws 13. A first sliding frame 14 is fixed to the surface of the first connecting plate 11, and a first sponge 15 is fixed to the inner surface of the first sliding frame 14. The surface of the first sponge 15 abuts against the surface of the first guide rail 5. Specifically, when the first guide rail 5 slides relative to the second sliding block 7, the first sponge 15 on the first sliding frame 14 moves synchronously relative to the first guide rail 5. The sliding mechanism allows the first sponge 15 to wipe and clean the surface of the first guide rail 5. The operator can also apply a small amount of lubricating oil to the first sponge 15 to lubricate the surface of the first guide rail 5, thus providing good care for the surface of the first guide rail 5. The operator only needs to remove and install the first fixing screw 13 to control the disassembly and assembly of the first connecting plate 11, which facilitates the disassembly and assembly of the first sliding frame 14 and the first sponge 15, making it convenient to replace the first sliding frame 14 and the first sponge 15 regularly.

[0030] The second guide rail care assembly includes a second connecting plate 16 and a second connecting piece 17. The upper and lower ends of the second connecting piece 17 are respectively fixed to the bottom end of the right-angle connector 9 and the top end of the second connecting plate 16 by second fixing screws 18. A second sliding frame 19 is fixed to the surface of the second connecting plate 16, and a second sponge 20 is fixed to the inner surface of the second sliding frame 19. The surface of the second sponge 20 abuts against the surface of the second guide rail 8. Specifically, when the second sliding block 10 slides on the surface of the second guide rail 8, the second sponge 20 on the second sliding frame 19 moves synchronously relative to the second guide rail 8. The sliding mechanism allows the second sponge 20 to wipe and clean the surface of the second guide rail 8. Operators can also apply a small amount of lubricant to the second sponge 20 to lubricate the surface of the second guide rail 8, thus providing excellent surface care. Furthermore, operators can easily disassemble and assemble the second connecting plate 16 by removing and installing the second fixing screw 18, facilitating the disassembly and assembly of the second sliding frame 19 and the second sponge 20, and enabling regular replacement of both.

[0031] The operating principle of this utility model is as follows: When the cylinder 3 is running, it can drive the lifting door body 1 to move up and down through the door panel connector 4, thereby realizing the opening and closing of the lifting door body 1. When the cylinder 3 drives the lifting door body 1 to move up and down, the first guide rail 5 on the lifting door body 1 slides relative to the first sliding block 7 on the cylinder connector 6. When the cylinder 3 drives the lifting door body 1 to move up and down, the second sliding block 10 can also slide synchronously on the surface of the second guide rail 8. That is, this pneumatic lifting door uses a combination of linear guide rail and cylinder to realize the stable lifting of the lifting door body 1, ensuring the stability and accuracy of the lifting door during the movement process, reducing noise, reducing wear parts, extending the service life of the lifting door, and is easy to operate and highly safe.

[0032] When the first guide rail 5 slides relative to the second sliding block 7, the first sponge 15 on the first sliding frame 14 slides synchronously relative to the first guide rail 5. This allows the first sponge 15 to wipe and clean the surface of the first guide rail 5. Furthermore, the operator can apply a small amount of lubricant to the first sponge 15 to lubricate the surface of the first guide rail 5, thus effectively protecting its surface. The operator only needs to remove and install the first fixing screw 13 to control the disassembly and assembly of the first connecting plate 11, facilitating the disassembly and assembly of the first sliding frame 14 and the first sponge 15, and enabling convenient periodic replacement of both. When the second sliding block 10 slides on the surface of the second guide rail 8, the second sponge 20 on the second sliding frame 19 slides synchronously relative to the second guide rail 8, so that the second sponge 20 can wipe and clean the surface of the second guide rail 8. The operator can also apply a small amount of lubricating oil to the second sponge 20, so that the second sponge 20 can also lubricate the surface of the second guide rail 8, thus providing good care for the surface of the second guide rail 8. The operator only needs to remove and install the second fixing screw 18 to control the disassembly and assembly of the second connecting plate 16, which facilitates the disassembly and assembly of the second sliding frame 19 and the second sponge 20, and makes it convenient to replace the second sliding frame 19 and the second sponge 20 regularly.
