Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically a hydraulic connector protective device. Background Technology

[0002] Hydraulic connectors are key components in hydraulic systems that enable detachable connections between pipelines and hydraulic components (such as pumps, valves, and cylinders). Their core function is to stably transmit high-pressure hydraulic oil while ensuring a leak-free system with minimal pressure loss, directly impacting the efficiency and safety of the hydraulic system. Common types include pipe fittings (such as welded and compression fittings, suitable for rigid pipe connections) and quick couplings (which allow for rapid insertion and removal without tools, often used in engineering machinery for accessory replacement). They are widely used in excavators, injection molding machines, machine tools, agricultural machinery, and other equipment. In the aerospace field, lightweight alloy materials are also used to meet the demands of harsh operating conditions.

[0003] As the core connecting component between pipelines and elements in a hydraulic system, the working state of the hydraulic connector directly affects the stability of the system. Existing hydraulic connector protection mostly adopts a simple one-piece sleeve structure, which requires disassembling the entire pipeline during disassembly, making it impossible to quickly inspect or replace the connector. Moreover, the sealing protection effect is not good, and external dust and moisture can easily penetrate into the interior, leading to aggravated damage to the connector. Therefore, a hydraulic connector protection device is proposed. Utility Model Content

[0023] Please see Figure 1-5This utility model provides a technical solution: a hydraulic connector protective device, including a protective housing 1, a protective housing 2, and a hydraulic connector body 3. One side of the hydraulic connector body 3 is connected to a pipe 13, and the other side is connected to a pipe 2 14. Four connecting blocks 14 are symmetrically fixedly connected to the outer wall of the protective housing 1, and four connecting blocks 25 are symmetrically fixedly connected to the outer wall of the protective housing 2. A connecting bolt 15 connects each pair of connecting blocks 14 and 25. A sealing strip 6 is adhered to the front surface of the protective housing 1, and a sealing groove 7 is formed on the rear surface of the protective housing 2. Outer sealing rings 8 and inner sealing rings 9 are adhered to both sides of the inner walls of the protective housing 1 and the protective housing 2. The hydraulic connector body 3 connects the pipe 13 and the pipe 25. The connection 14 uses connecting bolts 15 to connect protective housing 1 and protective housing 2 into a whole, protecting the hydraulic connector body 3 inside. This provides protection for the hydraulic connector, preventing it from being directly impacted by external forces. Unscrewing connecting bolts 15 allows for the removal of protective housing 1 and protective housing 2, facilitating quick and easy maintenance or replacement of the hydraulic connector. When connecting protective housing 1 and protective housing 2, the sealing strip 6 is compressed, filling the sealing groove 7. The outer sealing ring 8 and inner sealing ring 9 are also compressed and deformed, filling the gaps between protective housing 1 and protective housing 2 and pipe body 13 and pipe body 24. This prevents external dust and moisture from corroding the hydraulic connector, further improving the protective effect and providing a safe working environment for the hydraulic connector.

[0024] In this embodiment, specifically: four positioning strips 10 are fixedly connected to the inner sidewalls of both the protective housing 1 and the protective housing 2; this facilitates the positioning strips 10 to move synchronously with the protective housing 1 and the protective housing 2.

[0025] In this embodiment, specifically: eight positioning blocks 11 are symmetrically fixedly connected to the outer side wall of the hydraulic connector body 3, and positioning holes 12 are opened on the outer side wall of the positioning blocks 11; when installing the protective housing 1 and the protective housing 2, the positioning strip 10 is inserted into the positioning hole 12 to complete the rapid and accurate positioning of the protective housing 1 and the protective housing 2.

[0026] In this embodiment, specifically: both the protective shell 1 and the protective shell 2 are made of stainless steel; with the help of the high strength, deformation resistance and corrosion resistance of stainless steel, the protective shell 1 and the protective shell 2 can adapt to high pressure impact, oil corrosion and external environmental erosion.

[0027] In this embodiment, specifically: the sealing strip 6 is made of nitrile rubber; by utilizing the high elasticity of nitrile rubber, it can be inserted into the sealing groove 7 while ensuring that the sealing surface is always tightly fitted.

[0028] In this embodiment, specifically: the outer sealing ring 8 is made of polyurethane; with the help of the high wear resistance, excellent elasticity, tear resistance and strong weather resistance of polyurethane, the outer sealing ring 8 can be wear-resistant and tear-resistant when in contact with the external environment, ensuring interface sealing, resisting the scratching of external dust particles, and having good resistance to ultraviolet rays, ozone and common industrial pollutants. It is not easy to age and crack when exposed to the outdoor environment for a long time, which helps to extend the replacement cycle.

[0029] In this embodiment, specifically: the inner sealing ring 9 is made of fluororubber; with the help of the fluororubber's super oil resistance, wide temperature range adaptability and chemical corrosion resistance, the inner sealing ring 9 is oil-resistant, temperature-resistant and chemical-resistant, suitable for high-pressure sealing. Even if the hydraulic system experiences temperature rise due to overload or continuous operation, it can still maintain elasticity, avoid high-temperature aging and hardening leading to leakage, and resist anti-wear agents, extreme pressure agents and other additives in hydraulic oil, preventing chemical corrosion that could cause cracks and peeling of the inner sealing ring 9, ensuring long-term sealing reliability.

[0030] The working principle of this utility model is as follows: The hydraulic connector body 3 connects pipe body 13 and pipe body 14, and the connecting bolts 15 connect protective housing 1 and protective housing 2 into a whole, protecting the hydraulic connector body 3. This provides protection for the hydraulic connector, preventing direct external impact. The protective housing 1 and protective housing 2 can be removed by unscrewing the connecting bolts 15, facilitating quick and easy maintenance or replacement of the hydraulic connector. During the connection of protective housing 1 and protective housing 2, the sealing strip 6 is compressed, filling the sealing groove 7. The outer sealing ring 8 and inner sealing ring 9 are also compressed and deformed, filling the gaps between protective housing 1 and protective housing 2 and pipe body 13 and pipe body 14, preventing external dust and moisture from corroding the hydraulic connector, further improving the protective effect and providing a safe working environment for the hydraulic connector. Both protective housing 1 and protective housing 2 are made of stainless steel. The high strength, deformation resistance, and corrosion resistance of stainless steel allow protective housing 1 and protective housing 2 to be suitable for... To withstand high-pressure impacts, oil corrosion, and external environmental erosion, the sealing strip 6 is made of nitrile rubber. Utilizing the high elasticity of nitrile rubber, it can be inserted into the sealing groove 7 while ensuring a tight seal. The outer sealing ring 8 is made of polyurethane. Utilizing the high wear resistance, excellent elasticity, tear resistance, and strong weather resistance of polyurethane, the outer sealing ring 8 is wear-resistant and tear-resistant when in contact with the external environment, ensuring interface sealing, resisting scratches from external dust particles, and exhibiting good resistance to ultraviolet radiation, ozone, and common industrial pollutants. It is not prone to aging and cracking even after long-term exposure to outdoor environments, thus extending the replacement cycle. The inner sealing ring 9 is made of fluororubber. Utilizing the superior oil resistance, wide temperature range adaptability, and chemical corrosion resistance of fluororubber, the inner sealing ring 9 is oil-resistant, temperature-resistant, and chemical-resistant, suitable for high-pressure sealing. Even if the hydraulic system experiences temperature rise due to overload or continuous operation, it can still maintain elasticity, avoiding high-temperature aging and hardening that could lead to leakage. It can resist anti-wear agents, extreme pressure agents, and other additives in the hydraulic oil, preventing chemical corrosion that could cause cracks and peeling of the inner sealing ring 9, ensuring long-term sealing reliability.
