Technical Field

[0001] This utility model relates to the technical field of high-pressure oil pipes, and in particular to a high-pressure oil pipe with a double-layer protection structure. Background Technology

[0002] High-pressure oil pipes are a component of high-pressure oil circuits. They are generally composed of a steel wire winding skeleton layer and inner and outer oil-resistant and corrosion-resistant synthetic rubber. They are used for conveying media such as hydraulic oil pipes for engineering machinery, submarine natural gas, petroleum, irrigation, steel plants, and chemical plants.

[0003] Currently, traditional high-pressure oil pipes are in direct contact with the external environment during use, making them susceptible to corrosion and wear, which can lead to pipe rupture or leakage, affecting the normal operation of the equipment. Therefore, staff need to perform regular maintenance and inspections, and replace damaged high-pressure oil pipes with new ones in a timely manner. This not only increases maintenance costs but also reduces work efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a high-pressure oil pipe with a double-layer protection structure. By setting up the protective mechanism, the protective performance of the high-pressure oil pipe is improved, the oil pipe is prevented from directly contacting the external environment, and the risk of oil pipe damage is reduced.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a high-pressure oil pipe with a double-layer protection structure, comprising: an oil pipe and a protective mechanism, wherein the protective mechanism includes a sleeve, a first fixing member, a first connecting member, a fixing block, an anti-corrosion layer, and a waterproof layer, wherein the sleeve is wrapped around the outer wall of the oil pipe, the first fixing member is installed outside the sleeve, the first connecting member is threadedly connected to the first fixing member, the fixing block is installed on the outer wall of the first connecting member, the anti-corrosion layer is wrapped around the outer wall of the second connecting member, and the waterproof layer is wrapped around the outer wall of the anti-corrosion layer.

[0007] In addition, the high-pressure oil pipe with a double-layer protection structure proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the second fixing member is threadedly connected to the sleeve, the first base is installed inside the second fixing member, the first firing pin is installed on the first base, the first spring is sleeved on the outside of the first firing pin, the outer wall of the second fixing member has a groove, the second connecting member is sleeved on the outside of the second fixing member, the sliding block is installed on the outer wall of the second connecting member, the inside of the second connecting member has a storage groove, the steel ball is installed inside the storage groove, the second base is installed at the bottom of the second connecting member, the second firing pin is installed on the second connecting member, and the third spring is sleeved on the outside of the second firing pin.

[0009] Specifically, the fixing block is equipped with anti-slip grooves.

[0010] Specifically, a second spring is installed inside the sliding block.

[0011] Specifically, a dust cover is installed at the other end of the second connector.

[0012] Specifically, a sealing ring is fitted onto the outside of the sleeve.

[0013] Compared with existing technologies, this utility model has the following beneficial effects: The protective mechanism significantly enhances the durability and service life of the high-pressure oil pipe.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following description, with reference to the accompanying drawings, describes a high-pressure oil pipe with a double-layer protective structure according to an embodiment of the present invention.

[0023] like Figures 1-4 As shown in the figure, a high-pressure oil pipe with a double-layer protection structure according to an embodiment of the present invention includes: an oil pipe 1 and a protective mechanism 2.

[0024] The protective mechanism 2 includes a sleeve 21, a first fastener 22, a first connector 23, a fixing block 24, an anti-corrosion layer 26, and a waterproof layer 27.

[0025] Among them, the sleeve 21 is wrapped around the outer wall of the oil pipe 1, the first fixing member 22 is installed on the outside of the sleeve 21, the first connector 23 is threadedly connected to the first fixing member 22, the fixing block 24 is installed on the outer wall of the first connector 23, the anti-corrosion layer 26 is wrapped around the outer wall of the first connector 23, and the waterproof layer 27 is wrapped around the outer wall of the anti-corrosion layer 26.

[0026] Specifically, to further enhance the structural strength and durability of the oil pipe 1, a sleeve 21 is used to completely cover the oil pipe 1. During operation, the operator only needs to fix the protective layer, composed of the anti-corrosion layer 26 and the waterproof layer 27, into the gap reserved in the fixing block 24 on the first connector 23. Subsequently, the first fixing member 22 located on the outer wall of the first connector 23 is tightened in the threaded direction, causing the fixing block 24 to gradually compress until it is flush with the protective layer, thereby ensuring that the protective layer can be firmly fixed to the oil pipe 1. In addition, the anti-slip groove 25 on the fixing block 24 effectively increases the friction of the contact surface, which further increases its practicality and ensures its safety and reliability under high pressure.

[0027] In one embodiment of this application, such as Figure 1 As shown, the second fixing member 31 is threadedly connected to the sleeve 21, the first base 32 is installed inside the second fixing member 31, the first firing pin 33 is installed on the first base 32, the first spring 34 is sleeved on the outside of the first firing pin 33, the outer wall of the second fixing member 31 has a groove 35, the second connecting member 36 is sleeved on the outside of the second fixing member 31, the sliding block 37 is installed on the outer wall of the second connecting member 36, the inside of the second connecting member 36 has a storage groove 39, the steel ball 310 is installed inside the storage groove 39, the second base 311 is installed at the bottom of the second connecting member 36, the second firing pin 312 is installed on the second connecting member 36, and the third spring 313 is sleeved on the outside of the second firing pin 312.

[0028] Specifically, to further enhance the stability and safety of the oil pipe 1 during the docking process, the second connector 36 is tightly fitted to the outer wall of the second fixing member 31 via the sliding block 37. During the docking process, when the first striking pin 33 is subjected to external force, it will move along the first base 32 and compress the first spring 34 until it collides with the second striking pin 312. At this time, the second striking pin 312 will also be subjected to impact force, move along the second connector 36, and compress the third spring 313. The steel ball 310 is fixed in the groove 35 opened in the second fixing member 31 to play a fixing role, effectively preventing the second connector 36 from shaking or falling off during the docking process. In addition, the second spring 38 is installed inside the sliding block 37, which further increases the elasticity and stability of the sliding block 37, making the second connector 36 more stable and smooth when docking. When the oil pipe 1 needs to be removed, the sliding block 37 needs to be slid so that the steel ball 310 inside returns from the groove 35 in the second fixing member 31 to the storage groove 39 of the sliding block 37, thereby canceling the connection. At the same time, the dust cover 4 is installed at the other end of the second connector 36, which effectively prevents dust or debris from entering the oil pipe 1, ensuring the cleanliness and service life of the oil pipe 1.

[0029] In one embodiment of this application, such as Figure 4 As shown, anti-slip grooves 25 are installed on the fixing block 24.

[0030] Understandably, the design of the anti-slip groove 25 enhances the friction when installing the protective layer on the outside of the oil pipe 1, further ensuring the stability and reliability of the installation process.

[0031] In one embodiment of this application, such as Figure 3 As shown, a second spring 38 is installed inside the sliding block 37.

[0032] Understandably, the second spring 38 provides better cushioning and rebound force to the sliding block 37 during movement, ensuring stability and safety during docking.

[0033] In one embodiment of this application, such as Figure 1 As shown, a dust cover 4 is installed at the other end of the second connector 36.

[0034] Understandably, the dust cover 4 effectively prevents external dust or impurities from entering the oil pipe 1 when it is not in use, keeping the inside of the oil pipe 1 clean and extending its service life.

[0035] In one embodiment of this application, such as Figure 1 As shown, a sealing ring 5 is fitted on the outside of the sleeve 21.

[0036] Understandably, the sealing ring 5 further enhances the sealing performance of the high-pressure oil pipe 1 at the connection, effectively preventing oil leakage under high pressure, thereby ensuring the safety and stability of the high-pressure oil pipe 1 during operation.

[0037] Working Principle: To further enhance the structural strength and durability of the oil pipe 1, the sleeve 21 completely covers the oil pipe 1. During operation, the operator only needs to fix the protective layer, composed of the anti-corrosion layer 26 and the waterproof layer 27, into the gap reserved by the fixing block 24 on the first connector 23. Subsequently, the first fixing member 22 located on the outer wall of the first connector 23 is tightened in the thread direction, causing the fixing block 24 to gradually compress until it is flush with the protective layer, thereby ensuring that the protective layer can be firmly fixed to the oil pipe 1. In addition, the anti-slip groove 25 on the fixing block 24 effectively increases the friction of the contact surface, which further increases practicality and ensures its safety and reliability under high pressure. When docking, the second connector 36 is tightly fitted to the outer wall of the second fixing member 31 through the sliding block 37. During the docking process, when the first striking pin 33 is subjected to external force, it will move along the first base 32 and compress the first spring 34 until it collides with the second striking pin 312. At this time, the second firing pin 312 will also be impacted, moving along the second connector 36 and compressing the third spring 313. The steel ball 310 is fixed in the groove 35 in the second fixing member 31, which plays a fixing role and effectively prevents the second connector 36 from shaking or falling off during the docking process. In addition, the second spring 38 is installed inside the sliding block 37, which further increases the elasticity and stability of the sliding block 37, making the docking of the second connector 36 more stable and smooth. When it is necessary to remove the oil pipe 1, the sliding block 37 needs to be slid to return the steel ball 310 from the groove 35 in the second fixing member 31 to the receiving groove 39 of the sliding block 37, thereby canceling the connection. At the same time, the dust cover 4 is installed at the other end of the second connector 36, which effectively prevents dust or debris from entering the oil pipe 1, ensuring the cleanliness and service life of the oil pipe 1.
