[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0022] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a connector blank for an oil pipe connector, including a connector body 1, an oil pipe 2 threadedly connected to the outer left side of the connector body 1, a connecting groove 5 opened inside the left side of the connector body 1, a plurality of retaining grooves 6 opened on the inner wall of the connecting groove 5, a retaining block 7 being engaged inside the retaining groove 6, a connecting ring 8 being slidably connected to the outside of the retaining block 7, so that the connecting ring 8 is limited, a sealing ring 9 being fixedly connected to the inner side of the connecting ring 8, the sealing ring 9 being in contact with the outside of the oil pipe 2, so that the connecting ring 8 can seal the connection between the connector body 1 and the oil pipe 2, a placement groove 3 opened on the left side of the connector body 1, a placement ring 4 being inserted into the placement groove 3, the left side of the placement ring 4 being fixedly connected to the oil pipe 2, so that the placement ring 4 can re-seal the connection between the connector body 1 and the oil pipe 2.
[0023] After the connector body 1 is installed on the oil pipe 2, the placement ring 4 slides into the placement groove 3 to achieve a seal. By moving the locking block 7 inward, it slides into the connecting ring 8, thus freeing the connecting ring 8 from its limit. Then, the connecting ring 8 is pulled to the left, allowing it to slide inside the connecting groove 5. Subsequently, the locking block 7 is moved outward, engaging with the inside of the locking groove 6, thus limiting the connecting ring 8. This allows the sealing ring 9 to fit against the oil pipe 2, achieving a seal again. This prevents the liquid inside the oil pipe 2 from leaking to the outside, resulting in higher safety and a longer service life for both the oil pipe 2 and the connector, thus improving economic efficiency.
[0024] Example 2: Based on Example 1, to facilitate the pulling of the locking block 7, the connecting ring 8 has multiple mounting slots 11 inside. The locking block 7 is slidably connected inside the mounting slots 11, which provide mounting space for the locking block 7. A mounting piece 12 is fixedly connected to the end of the locking block 7 away from the slot 6. The mounting piece 12 is slidably connected inside the mounting slot 11, which limits the mounting piece 12, allowing it to slide smoothly. The end of the mounting piece 12 away from the locking block 7 is fixedly connected... A pull rope 13 is attached, which is slidably connected inside the mounting groove 11. The mounting groove 11 limits the pull rope 13 so that it will not deviate when sliding. The other end of the pull rope 13 is fixedly connected to a pull ring 15, which is slidably connected to the outside of the left side of the connecting ring 8. The connecting ring 8 provides installation space for the pull ring 15. An elastic element 14 is sleeved on the outside of the pull rope 13. One end of the elastic element 14 is fixedly connected to the mounting plate 12, and the other end of the elastic element 14 is fixedly connected to the inner wall of the mounting groove 11.
[0025] When the locking block 7 needs to be pulled, the pull ring 15 is pulled to the left, causing one end of the pull rope 13 to move to the left, and the other end of the pull rope 13 to pull the mounting piece 12 to move inward. This causes the mounting piece 12 to compress the elastic element 14 and deform, thus causing the locking block 7 to slide into the interior of the mounting groove 11. Conversely, by releasing the pull ring 15, the elastic element 14 is reset, causing the elastic element 14 to push the mounting piece 12 to move outward, so that the mounting piece 12 can push the locking block 7 to engage with the interior of the locking groove 6.
[0026] Example 3: Based on Example 2, in order to further improve the sealing performance, a sealing ring 9 is fixedly connected to the inner side of the connecting ring 8. A limiting groove 16 is opened on the inner side of the sealing ring 9, and a sealing groove 10 is opened on the outer side of the oil pipe 2. The sealing ring 9 fits in close with the inside of the sealing groove 10, so that the sealing ring 9 has a higher sealing effect on the joint body 1 and the oil pipe 2. A limiting ring 17 is fixedly connected to the inner wall of the sealing groove 10. The sealing ring 9 slides in close with the outer side of the limiting ring 17, so that the sealing ring 9 can be squeezed and deformed. The limiting ring 17 fits in close with the inside of the limiting groove 16, so that the sealing ring 9 can be limited again.
[0027] When the sealing ring 9 slides into the sealing groove 10, the sealing groove 10 is deformed by the limiting ring 17, which allows the sealing ring 9 to fill the interior of the sealing groove 10, and the limiting ring 17 to fit into the interior of the limiting groove 16, thereby improving the sealing effect of the connecting ring 8.
[0028] The working process of this utility model is as follows:
[0029] After the connector body 1 is installed on the oil pipe 2, the placement ring 4 slides into the placement groove 3, thus achieving a seal. Pulling the pull ring 15 to the left moves one end of the pull rope 13 to the left, causing the other end of the pull rope 13 to pull the mounting plate 12 inward. This causes the mounting plate 12 to compress the elastic element 14, deforming it and causing the locking block 7 to slide into the mounting groove 11. This removes the limiting effect on the connecting ring 8, allowing it to slide inside the connecting groove 5. The sealing ring 9 then slides outside the oil pipe 2 and is deformed by the pressure of the oil pipe 2. When the sealing ring 9 reaches the position of the sealing groove 10, the sealing groove 10 resets. The sealing ring 9 is deformed by the limiting ring 17, which allows the sealing ring 9 to fill the interior of the sealing groove 10. This allows the limiting ring 17 to fit into the interior of the limiting groove 16, resulting in a better sealing effect for the connecting ring 8. At this time, by releasing the pull ring 15, the elastic element 14 can perform a reset movement, which allows the elastic element 14 to push the mounting piece 12 to move outward. This allows the mounting piece 12 to push the locking block 7 to engage with the interior of the locking groove 6, thereby limiting the connecting ring 8. This allows the sealing ring 9 to fit into the oil pipe 2, thus sealing it again. This prevents the liquid inside the oil pipe 2 from flowing out, resulting in higher safety and a longer service life for the oil pipe 2 and the connector, thus increasing economic efficiency.
