Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion equipment technology, and more specifically, to a protective sleeve with vacuum anti-corrosion effect. Background Technology

[0002] In certain industrial environments, equipment and components often face corrosion problems, which not only shorten the service life of the equipment but may also lead to safety hazards. In particular, nuts and screws exposed to humid or corrosive gas environments are easily corroded, thus affecting their performance and operational reliability.

[0003] Based on the above, the inventors have discovered that for nuts and screws exposed to humid or corrosive gas environments, traditional anti-corrosion measures often rely on coatings or chemical treatments. However, these methods may gradually fail over long-term use, especially under complex working conditions, resulting in poor anti-corrosion effects. Furthermore, after anti-corrosion treatment of nuts and screws exposed to humid or corrosive gas environments, it is generally inconvenient to monitor changes in the surrounding environment in real time, leading to unreliable anti-corrosion effects. Therefore, in view of this, the inventors have researched and improved existing structures to provide a protective sleeve with vacuum anti-corrosion effects, aiming to achieve greater practical value. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figures 1-4 A protective sleeve with vacuum corrosion protection includes an outer protective sleeve for protecting the internal hexagonal nut and screw. The outer protective sleeve consists of an upper part 1 and a lower part 2. An annular groove 3 is formed on the inner side of the top opening of the upper part 1, and an O-ring 4 is embedded in the annular groove 3. An opening 5 is formed at the bottom of the lower part 2, which is connected to the interior of the lower part 2. An annular groove 6 is formed on the inner wall of the opening 5, and an O-ring 7 is embedded in the annular groove 6. An air humidity detector 8 is installed at the bottom of the lower part 2. In use, the application of O-ring 4 and O-ring 7 further improves the sealing performance, ensures the long-term stability of the vacuum environment, and avoids the sealing failure caused by changes in the external environment.

[0034] See Figure 1 The lower part 2 of the outer protective sleeve is located at the bottom of the upper part 1 of the outer protective sleeve, and the two are integrally formed. When in use, the integral forming design of the upper part 1 and the lower part 2 of the outer protective sleeve not only enhances the strength of the overall structure, but also simplifies the installation and disassembly process and improves the convenience of use.

[0035] See Figure 2 The upper part 1 of the outer protective sleeve has a hemispherical structure, and the internal hexagonal nut is located inside the upper part 1 of the outer protective sleeve. In use, the design of combining the hemispherical upper part 1 of the outer protective sleeve and the columnar lower part 2 of the outer protective sleeve not only conforms to the shape characteristics of the nut and the screw, but also minimizes the internal space, thereby reducing the cost of maintaining the vacuum environment.

[0036] See Figure 2 The lower part 2 of the outer protective sleeve has a columnar structure, and the screw is located inside the lower part 2 of the outer protective sleeve.

[0037] See Figure 3 The inner wall of the lower part 2 of the outer protective sleeve is provided with an internal thread that matches the external thread of the screw. The inner wall of the lower part 2 of the outer protective sleeve is connected to the screw through the internal thread. In use, the internal thread ensures a stable connection between the lower part 2 of the outer protective sleeve and the screw, preventing it from falling off.

[0038] See Figure 1 The probe of the air humidity detector 8 extends through the opening 5 into the interior of the lower part 2 of the outer protective sleeve.

[0039] See Figure 4 The probe of the air humidity detector 8 is sealed to the lower part 2 of the outer protective sleeve by an O-ring 7.

[0040] In use: After installing the hexagonal nut and screw onto the metal surface, place the hexagonal nut inside the upper part 1 of the outer protective sleeve, ensuring its stable position and matching the hemispherical structure of the upper part 1. Next, insert the screw into the lower part 2 of the outer protective sleeve, and connect it to the external thread of the screw through the internal thread on the inner sidewall of the lower part 2, thus achieving a secure fixation. During this process, it is necessary to ensure a tight connection between the screw and the lower part 2 of the outer protective sleeve to avoid any gaps that may affect the formation of the vacuum environment.

[0041] Subsequently, an external miniature vacuum pump is used to extract the air from inside the outer protective sleeve through the opening 5 at the bottom of the lower part 2, creating a stable vacuum environment. In this operation, O-ring 4 and O-ring 7 are respectively embedded in annular groove 3 and annular groove 6, playing a crucial sealing role to prevent the intrusion of external moisture or corrosive gases, while maintaining the long-term stability of the vacuum environment.

[0042] After vacuum extraction is completed, the air humidity detector 8 is installed at the bottom of the lower part 2 of the outer protective sleeve, with its probe extending through the opening 5 into the interior of the lower part 2 of the outer protective sleeve to monitor the humidity changes of the internal environment in real time. If an abnormal increase in humidity is detected, it indicates that there may be a seal failure or external gas intrusion. At this time, the user can take appropriate measures to maintain the system in a timely manner to ensure the reliability of the anti-corrosion effect.
