Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder sealing technology, and in particular to a cylinder dust seal with waterproof function. Background Technology

[0002] Hydraulic cylinder dust seals are sealing elements installed on hydraulic cylinders to prevent external impurities, dust, water, and moisture from entering the cylinder. The FW type dust seal, as a waterproof hydraulic cylinder dust seal, plays several crucial roles. Its unique outer baffle design effectively prevents water, vapor, and impurities from entering the system through the groove bottom diameter, avoiding rust and corrosion of internal seals and guide components due to water erosion, and accelerated wear due to impurities entering, ensuring normal cylinder operation. It offers significant advantages in humid or underwater operating environments. Simultaneously, the FW type dust seal has excellent dust-scraping performance and is highly wear-resistant, efficiently removing dust from the piston rod surface. It is not easily damaged even with long-term use, reducing maintenance costs. Furthermore, it is a standard component, compatible with standard mounting grooves for easy installation, and its waterproof properties make it suitable for various water-contacting equipment scenarios such as construction, shipbuilding, and agricultural irrigation, comprehensively improving equipment performance and reliability.

[0003] The dust seals currently used in hydraulic cylinders have structural design flaws, lacking a flange for protection on the outer side. This allows dust and impurities from the external environment to easily penetrate the cylinder body. The entry of these impurities disrupts the cylinder's seal, causing it to fail. In the event of seal failure, the dust seal will be subjected to additional pressure and wear, leading to damage and significantly shortening its lifespan. Therefore, a waterproof dust seal for hydraulic cylinders is proposed to address these issues. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a waterproof dust seal for hydraulic cylinders, aiming to improve the existing hydraulic cylinder dust seal structure, which has defects such as no outer flange, allowing dust and impurities to easily enter the cylinder body, causing seal failure, wear and damage to the dust seal, and shortening its service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waterproof cylinder dustproof ring, comprising a dustproof ring body, wherein a first reinforcing rib is fixedly connected inside the dustproof ring body, a second reinforcing rib is fixedly connected to the lower surface of the dustproof ring body, an extension is fixedly connected to one side of the upper surface of the dustproof ring body, and a barrier strip is provided on the inner wall of the dustproof ring body.

[0006] Furthermore, the dustproof ring body includes a baffle portion, which is disposed on the outside of the dustproof ring body. A dustproof lip is fixedly connected to one side of the outer wall of the baffle portion, and an installation groove is formed inside the dustproof ring body.

[0007] Furthermore, the reinforcing rib is disposed inside the baffle portion, and the reinforcing rib is L-shaped.

[0008] Furthermore, the barrier strip is disposed on the inner wall of the mounting groove, and the barrier strip is corrugated, and the barrier strip is used to block dust and water flow.

[0009] Furthermore, the mounting groove is provided on one side of the barrier portion, and the mounting groove is used to install mechanical components.

[0010] Furthermore, the dustproof lip is inclined and is used to block dust.

[0011] Furthermore, the extension is integrally formed with the upper surface of the dustproof ring body, and the extension is used to enhance the sealing performance of the dustproof ring.

[0012] Furthermore, the second reinforcing rib is disposed on one side of the lower surface of the dustproof ring body, and the second reinforcing rib is used to enhance the compressive strength of the dustproof ring.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the internal reinforcing ribs one and two enhance the compressive and tensile strength of the dustproof ring, improving its mechanical properties and sealing effect. The integrally molded extension further strengthens the seal, preventing the intrusion of external dust and moisture. The inclined dustproof lip effectively blocks dust entry, improving the dustproof effect. The mounting groove design facilitates the installation of mechanical components and enhances structural stability. The corrugated barrier strip better blocks dust and water flow, ensuring the cleanliness and dryness of the equipment's interior and preventing damage to internal cylinder components. Furthermore, the L-shaped reinforcing rib, located inside the baffle section, helps improve the strength and durability of the dustproof ring, providing longer-lasting protection suitable for high-load working environments.

The second reinforcing rib 3 primarily improves the compressive strength of the dustproof ring, especially under external pressure, effectively dispersing pressure and reducing the risk of deformation. An extension portion 4 is fixedly connected to one side of the upper surface of the dustproof ring body 1. The extension portion 4 is designed to improve the sealing performance of the dustproof ring. Through its integral molding structure with the dustproof ring body 1, the extension portion 4 provides a stronger sealing effect, preventing external dust and moisture from entering the cylinder. A barrier strip 5 is provided on the inner wall of the dustproof ring body 1. The barrier strip 5 has a corrugated structure, mainly used to block the entry of dust, water, and other impurities, ensuring... The working fluid inside the hydraulic cylinder is cleaned.

The dustproof lip 102 is inclined, effectively blocking external dust and impurities and preventing them from entering the hydraulic cylinder, further enhancing the dustproof effect. An installation groove 103 is provided inside the dustproof ring body 1. The installation groove 103 is used to install other mechanical parts or fixing devices, ensuring that the dustproof ring body 1 can be firmly fixed in the corresponding position of the hydraulic cylinder during use, maintaining the stability of the overall structure.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The first reinforcing rib 2 is located inside the baffle 101 and is L-shaped. The barrier strip 5 is located on the inner wall of the mounting groove 103 and is corrugated. The barrier strip 5 is used to block dust and water flow.

[0024] Specifically, reinforcing rib 2 is installed inside the baffle part 101.

These two reinforcing ribs are located inside the dust cover ring and on its lower surface, respectively, enhancing the compressive and tensile strength of the dust cover ring, thereby improving its mechanical properties and enabling it to work effectively under high pressure. Reinforcing rib 1 2 has an L-shaped structure, further improving the overall strength of the dust cover ring body 1, giving it better resistance to deformation, and ensuring that the hydraulic cylinder is not easily deformed or damaged during use.

[0026] Secondly, an extension 4 is provided on one side of the upper surface of the dustproof ring body 1. The extension 4 is integrally formed with the dustproof ring body 1, which enhances the sealing performance of the dustproof ring and effectively prevents external dust and moisture from entering the oil cylinder, avoiding contamination of the oil and protecting the normal operation of the internal components of the oil cylinder. The design of the extension 4 also effectively improves the service life of the dustproof ring. On the inner wall of the dustproof ring body 1, barrier strips 5 are provided, and these barrier strips 5 adopt a corrugated structure, which can effectively block external dust and water flow, further improving the dustproof effect.

[0027] In addition, the position of the barrier strip 5 is set on the inner wall of the mounting groove 103 to ensure that it can continue to function during operation and prevent impurities from entering the oil cylinder.
