Technical Field
[0001] This utility model relates to the field of engine oil pipe connectors, specifically an engine oil pipe connector that is easy to disassemble and assemble. Background Technology
[0002] The engine is the core power component in vehicles and various mechanical equipment, and its normal operation depends on a stable and reliable fuel supply system. Within the fuel supply system, the fuel line connector, as a key component connecting the fuel line to the engine, directly affects the engine's efficiency and safety. Traditional engine oil pipe fittings often present many inconveniences during disassembly and assembly, such as complex operation and long time consumption, which affects their maintenance time. Furthermore, if the internal pressure increases during use, additional pressure relief operation is required to release the pressure, as they cannot automatically relieve pressure, which may lead to safety hazards due to pressure accumulation. Utility Model Content
[0003] The purpose of this invention is to provide an engine oil pipe connector that is easy to install and disassemble, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the following technical solution is provided: an engine oil pipe connector that is easy to assemble and disassemble, comprising an oil pipe and a connector. A connector is provided at one end of the oil pipe, and an outer tube is provided on the outer side of both ends of the oil pipe at the connector. L-shaped locking blocks facing the connector are evenly distributed on the inner side of the other end of each outer tube, and a locking post is provided at the other end of each L-shaped locking block. The L-shaped locking block and the locking post form a U-shape. A transverse positioning groove is provided on the outer wall of the oil pipe corresponding to the locking post and the L-shaped locking block. The locking post and the L-shaped locking block are engaged with the oil pipe through the corresponding positioning groove. A compression groove is provided at the middle position of the top and bottom of the inner side of the connector, and a spring strip is provided at the middle position of each compression groove. The other end of each strip is provided with an arc-shaped extrusion block, and the size of the extrusion block is consistent with the extrusion groove. The middle position of each side of the extrusion groove away from the extrusion block is provided, so that the inner tubes at both ends of the connector can be inserted between the two sets of oil pipes. The L-shaped locking block and locking post can be slidably locked onto the outside of the oil pipe and locked in place by rotating clockwise. This allows for convenient assembly and disassembly of the connector and oil pipes, facilitating their maintenance and repair. When the pressure of the internal circulating medium increases, it can squeeze the extrusion block and spring strip, causing the extrusion block to move and expose the pressure relief port. This allows some medium to be discharged to the outside of the connector through the pressure relief port, L-shaped pressure relief pipe and connecting pipe, enabling pressure relief operations and preventing damage to the oil pipes and connectors due to excessive internal pressure.
[0005] As a further technical solution of this utility model, the inner side of the oil pipes at both ends of the connector is provided with an inner pipe, and an annular sealing block is provided between the outer pipe and the inner pipe at both ends of the connector to fit with the oil pipe, so that the annular sealing block between the outer pipe and the inner pipe fits with the oil pipe, and can seal the oil pipe to prevent leakage.
[0006] As a further technical solution of this utility model, an annular block is provided on the outer side of the oil pipe at the other end of the outer tube, and threaded holes are evenly provided at the corresponding positions of the annular block and the outer tube. Fixing bolts are threadedly connected to the corresponding threaded holes of the annular block and the outer tube. After the outer tube is rotated and locked in place, the threaded holes on the outer tube and the annular block can be aligned. Then, the fixing bolts can be screwed into the corresponding threaded holes to fix the outer tube and the oil pipe. This secondary fixation can prevent them from loosening.
[0007] As a further technical solution of this utility model, each of the L-shaped locking blocks is provided with an arc-shaped groove three in the oil pipe in the clockwise direction, and each of the L-shaped locking blocks is engaged with the oil pipe through the arc-shaped groove three, so that when the L-shaped locking block moves in the clockwise direction, it can be engaged into the arc-shaped groove three, which facilitates subsequent engagement.
[0008] As a further technical solution of this utility model, an arc-shaped groove is provided on the outer wall of the oil pipe in the clockwise direction at the end of the L-shaped block away from the locking post, and the L-shaped block is engaged with the oil pipe through the arc-shaped groove, so that the end of the L-shaped block away from the locking post is engaged in the arc-shaped groove in the clockwise direction, which facilitates the movement of the L-shaped block.
[0009] As a further technical solution of this utility model, an arc-shaped groove is provided on the outer wall of the oil pipe in the clockwise direction of the locking pin, and the locking pin is engaged with the oil pipe through the arc-shaped groove. The L-shaped locking block drives the locking pin to rotate clockwise and engage into the arc-shaped groove, which can improve the locking effect.
[0010] As a further technical solution of this utility model, a limiting block is provided at the middle position of the other two sides of the bottom of the extrusion block, and a limiting groove is provided in the corresponding connector of the limiting block. The limiting block is slidably connected to the corresponding limiting groove, so that when the extrusion block moves, it can drive the limiting block to move in the limiting groove, thereby limiting the movement of the extrusion block and preventing it from deviating, thus affecting its movement effect.
[0011] As a further technical solution of this utility model, each of the connectors corresponding to the pressure relief ports on both sides of the extrusion groove is provided with an L-shaped pressure relief pipe, and the other end of each L-shaped pressure relief pipe extends to the outside of the connector and is provided with a connecting pipe, so that some medium enters the L-shaped pressure relief pipe through the pressure relief port and flows into the connecting pipe through the L-shaped pressure relief pipe, thereby discharging some medium and performing pressure relief operation.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By aligning the L-shaped locking block on the inner side of the outer tube with the positioning groove, the inner tubes at both ends of the connector can be inserted between the two sets of oil pipes. The L-shaped locking block and the locking pin can slide and engage in the positioning groove. Then, the connector and the outer tube can be rotated clockwise, causing the outer tube to drive the L-shaped locking block and the locking pin to rotate clockwise and engage in the arc groove three, arc groove two and arc groove one. This allows for the initial fixing of the connector and the oil pipe. Then, fixing bolts can be used to fix it. This allows for convenient assembly and disassembly of the connector and the oil pipe, facilitating maintenance and repair. 2. By applying internal pressure to the extrusion block, the extrusion block moves into the extrusion groove after being pressurized. At the same time, the extrusion spring strip undergoes elastic deformation to generate elastic force, which can cause the extrusion block to be extruded to expose the pressure relief port. This allows some of the medium to enter the L-shaped pressure relief pipe through the pressure relief ports on both sides of the extrusion groove, and then be discharged to the outside of the connector through the connecting pipe. This can be used for pressure relief operations and can prevent damage to the oil pipe and connector caused by excessive internal pressure. Attached Figure Description

[0015] Please see Figures 1-5This utility model provides an embodiment of an engine oil pipe connector that is easy to assemble and disassemble, comprising an oil pipe 1 and a connector 2. The connector 2 is provided at one end of the oil pipe 1, and both ends of the connector 2 have outer tubes 3 on the outer sides of the oil pipe 1. Both ends of the connector 2 have inner tubes 4 on the inner sides of the oil pipe 1. An annular sealing block 8 is provided between the outer tube 3 and the inner tube 4 at both ends of the connector 2, fitting snugly against the oil pipe 1. The inner side of the other end of the outer tube 3 is evenly provided with L-shaped locking blocks 17 facing the connector 2, and the other end of the inner side of each L-shaped locking block 17 has a locking post 16. The L-shaped locking block 17 and the locking post 16 form a U-shape. The locking post 16 and the L-shaped locking block 17 correspond to the oil... The outer wall of pipe 1 is provided with a transverse positioning groove 14, and the locking post 16 and the L-shaped locking block 17 are locked with the oil pipe 1 through the corresponding positioning groove 14. The L-shaped locking block 17 is provided with an arc groove 3 18 in the oil pipe 1 in the clockwise direction, and the L-shaped locking block 17 is locked with the oil pipe 1 through the arc groove 3 18. The outer wall of the oil pipe 1 in the clockwise direction of the end of the L-shaped locking block 17 away from the locking post 16 is provided with an arc groove 2 15, and the L-shaped locking block 17 is locked with the oil pipe 1 through the arc groove 2 15. The outer wall of the oil pipe 1 in the clockwise direction of the locking post 16 is provided with an arc groove 13, and the locking post 16 is locked with the oil pipe 1 through the arc groove 13. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the annular sealing block 8 is positioned between the outer tube 3 and the inner tube 4 at both ends of the connector 2. Then, the L-shaped locking block 17 on the inner side of the outer tube 3 can be aligned with the positioning groove 14. The inner tubes 4 at both ends of the connector 2 can be inserted between the two sets of oil pipes 1. During insertion, the L-shaped locking block 17 and the locking pin 16 can slide and engage within the positioning groove 14. After the positioning is complete, the connector 2 and the outer tube 3 can be rotated clockwise, causing the outer tube 3 to rotate clockwise and engage with the L-shaped locking block 17 and the locking pin 16 into the arc-shaped groove 3 18 and the arc-shaped groove 2 15. Within the arc-shaped groove 13, the L-shaped locking block 17 and the locking post 16 can be tightly engaged with the arc-shaped groove 18, the arc-shaped groove 15 and the arc-shaped groove 13 respectively, which can initially fix the connector 2 and the oil pipe 1, and facilitate the assembly and disassembly of the connector 2 and the oil pipe 1, making it convenient for maintenance and repair. During connection, the annular sealing block 8 can undergo elastic deformation under external pressure during the connection process, tightly filling the gap between the outer pipe 3, the inner pipe 4 and the oil pipe 1 to form a sealing structure, which can prevent oil leakage. A compression groove 10 is provided at the middle position of the top and bottom of the inner side of the connector 2, and a spring strip 11 is provided at the middle position of the compression groove 10. The other end of the spring strip 11 is provided with an arc-shaped compression block 9, and the size of the compression block 9 is the same as that of the compression groove 10. A pressure relief port is provided at the middle position of both sides of the end of the compression groove 10 away from the compression block 9. An L-shaped pressure relief pipe 7 is provided in the connector 2 corresponding to the pressure relief port on both sides of the compression groove 10, and the other end of the L-shaped pressure relief pipe 7 extends to the outside of the connector 2 and is provided with a connecting pipe 6. Specifically, such as Figure 1 and Figure 4 As shown, the medium flows through the oil pipe 1 and connector 2. When the internal pressure increases, it acts on the extrusion block 9. After being pressurized, the extrusion block 9 moves into the extrusion groove 10 and simultaneously extrudes the spring strip 11. The spring strip 11 undergoes elastic deformation and generates elastic force. When the pressure reaches a certain level, the extrusion block 9 extrudes the pressure relief port, allowing some medium to enter the L-shaped pressure relief pipe 7 through the pressure relief ports on both sides of the extrusion groove 10, and then be discharged to the outside of the connector 2 through the connecting pipe 6, thereby performing a pressure relief operation. This prevents damage to the oil pipe 1 and connector 2 due to excessive internal pressure, ensuring the normal use and safety of the engine oil pipe connector. When the pressure returns to normal, the spring strip 11 rebounds, causing it to move the extrusion block 9 inward again to block the pressure relief port, preventing further leakage of the medium and maintaining the normal pressure environment inside the engine oil pipe connector. An annular block 5 is provided on the outer side of the oil pipe 1 at the other end of the outer pipe 3, and threaded holes are evenly provided at the corresponding positions of the annular block 5 and the outer pipe 3, and fixing bolts 12 are threadedly connected in the corresponding threaded holes of the annular block 5 and the outer pipe 3. Specifically, such as Figure 1 As shown, after the outer tube 3 is rotated and engaged with the oil pipe 1, the threaded hole on the annular block 5 can be aligned with the threaded hole inside the outer tube 3. Then, the fixing bolt 12 can be screwed into the threaded hole inside the annular block 5 and the outer tube 3 for secondary fixation, making the connection more stable and effectively preventing loosening or falling off during use. This can improve the speed of installation and disassembly. The fixing bolt 12 is made of high-strength material, which has sufficient strength and wear resistance and can maintain its position for a long time. Limiting blocks 20 are provided in the middle of the other two sides of the bottom of the extrusion block 9, and limiting grooves 19 are provided in the connectors 2 corresponding to the limiting blocks 20, and the limiting blocks 20 are slidably connected to the corresponding limiting grooves 19. Specifically, such as Figure 4 As shown, when the extrusion block 9 moves, it can drive the limiting blocks 20 on both sides of the bottom to move within the limiting groove 19, which can make the extrusion block 9 move more smoothly and prevent the extrusion block 9 from deviating or getting stuck during the movement, thus affecting the movement of the extrusion block 9.
[0016] The working principle of this utility model is as follows: In use, align the L-shaped locking block 17 on the inner side of the outer tube 3 with the positioning groove 14. Then, insert the inner tubes 4 at both ends of the connector 2 between the two sets of oil pipes 1. During insertion, the L-shaped locking block 17 and the locking pin 16 can slide and engage within the positioning groove 14. After proper engagement, rotate the connector 2 and the outer tube 3 clockwise. This causes the outer tube 3 to rotate clockwise, engaging the L-shaped locking block 17 and the locking pin 16 into the arc-shaped grooves 18, 15, and 13 respectively. This allows the L-shaped locking block 17 and the locking pin 16 to engage tightly with the arc-shaped grooves 18, 15, and 13, respectively, enabling the connector 2 to engage with the oil pipe 1. After initial fixing, the connector 2 and oil pipe 1 can be easily assembled and disassembled, facilitating maintenance and repair. During connection, the annular sealing block 8 undergoes elastic deformation under external pressure, tightly filling the gap between the outer pipe 3, inner pipe 4, and oil pipe 1 to form a sealing structure, preventing oil leakage. After rotation and locking, the threaded hole on the annular block 5 can be aligned with the threaded hole inside the outer pipe 3. Then, the fixing bolt 12 can be screwed into the threaded holes of the annular block 5 and the outer pipe 3 for secondary fixing, making the connection more stable and effectively preventing loosening or detachment during use, thus improving efficiency. The installation and disassembly speed is fast, and the fixing bolt 12 is made of high-strength material with sufficient strength and wear resistance, which can maintain its position for a long time. When it is put into use, it can allow the medium in the oil pipe 1 and the connector 2 to flow. When the internal pressure increases, it can make its internal pressure act on the extrusion block 9. After being pressured, the extrusion block 9 moves into the extrusion groove 10. When the extrusion block 9 moves, it can drive the limit blocks 20 on both sides of the bottom to move in the limit groove 19, which can make the extrusion block 9 move more smoothly and prevent the extrusion block 9 from deviating or getting stuck during the movement, thus affecting the movement of the extrusion block 9. At the same time, it can make the extrusion block 9 compress the spring strip 1. 1. The spring bar 11 undergoes elastic deformation to generate elastic force. When the pressure reaches a certain level, the extrusion block 9 extrudes the pressure relief port, allowing some medium to enter the L-shaped pressure relief pipe 7 through the pressure relief ports on both sides of the extrusion groove 10, and then be discharged to the outside of the connector 2 through the connecting pipe 6, thereby performing pressure relief operation. This prevents damage to the oil pipe 1 and connector 2 due to excessive internal pressure, ensuring the normal use and safety of the engine oil pipe joint. When the pressure returns to normal, the spring bar 11 rebounds, causing it to move the extrusion block 9 inward again to block the pressure relief port, preventing further leakage of the medium and maintaining the normal pressure environment inside the engine oil pipe joint.
