DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example
[0024] See also Figure 1-4The present embodiment provides an oil pipe joint with an anti-slip structure, including a sleeve 1, one end of the sleeve 1 is connected to a connecting pipe 4, and positioning slide plates 5 are symmetrically installed on both sides of one end of the connecting pipe 4. A ferrule 7 is sleeved and installed on the outer ring surface of the connecting pipe 4, and a clamping block 8 is symmetrically installed on the top and bottom of one end of the ferrule 7. Slide grooves 701 are symmetrically opened on both sides of the inside of the ferrule 7, and a spring 9 is fixedly connected to one end of the ferrule 7. The spring 9 is slidably sleeved on the outside of the connecting pipe 4, and one end of the spring 9 is fixedly connected to one end of the sleeve 1. A hexagonal nut 10 is sleeved and installed on the outer ring surface of one end of the connecting pipe 4, and an annular groove 1010 is opened on one side surface of the hexagonal nut 10, and a clamping groove 1011 is symmetrically opened on the top and bottom of the inner side of the annular groove 1010, and the inner side surface size composed of the annular groove 1010 and the clamping groove 1011 matches the size of one end of the ferrule 7 and the clamping block 8. After the hexagonal nut 10 is threadedly connected to the oil pipe threaded head of the equipment, one end of the spring 9 squeezes the sleeve 7 to move in the direction of the hexagonal nut 10. At this time, the slide groove 701 inside the sleeve 7 slides on the positioning slide plate 5. When one end of the sleeve 7 and the block 8 are in contact with one side of the hexagonal nut 10, the orientation of the hexagonal nut 10 is adjusted so that one end of the sleeve 7 and the block 8 are respectively inserted into the inner sides of the annular groove 1010 and the groove 1011. At this time, the sleeve 7 cannot be rotated due to the connection structure of the slide groove 701 and the positioning slide plate 5, and the groove 1011 on the hexagonal nut 10 is stuck by the block 8. Therefore, when the sleeve 7 cannot rotate, the hexagonal nut 10 cannot rotate either, thereby effectively preventing the vibration generated during the operation of the equipment from causing the hexagonal nut 10 to rotate counterclockwise, and solving the problem of the hexagonal nut 10 loosening and falling off.
[0025] In this embodiment, if Figure 1 and Figure 2 As shown, a circular nut 2 is installed at the end of the sleeve 1 away from the connecting tube 4, a tapered thread 101 is opened at the inner end of the sleeve 1, and a forked thread seat 3 is installed at one end of the circular nut 2. The edge of one end of the circular nut 2 coincides with the edge of one end of the sleeve 1, and the inner hollow hole grooves of the circular nut 2 and the sleeve 1 match the outer size of the rubber tube. After the inner side of the sleeve 1 is sleeved on the outside of the rubber tube, the forked thread seat 3 on the circular nut 2 is threadedly connected with the tapered thread 101. During installation, the circular nut 2 is first sleeved on the rubber tube, and then the inner side of the sleeve 1 is sleeved on the rubber tube, and then the forked thread seat 3 is threadedly connected with the tapered thread 101. At this time, the more the forked thread seat 3 is tightened, the more it is affected by the tapered thread 101 and deformed, and the rubber tube is tightly clamped, thereby preventing the sleeve 1 from falling off the rubber tube.
[0026] In this embodiment, if Figure 2As shown, one end of the connecting tube 4 is inserted into the interior of the sleeve 1, and the part of the connecting tube 4 located inside the sleeve 1 is in the shape of a threaded tube, and one end of the threaded tube can squeeze the inner side of one end of the rubber tube. One end of the sleeve 1 is provided with a hexagonal surface. When the sleeve 1 is sleeved on the rubber tube, the threaded tube end of the connecting tube 4 is inserted into the interior of the rubber tube, and the sleeve 1 is rotated clockwise by tapping. During this process, a helper can be used to clamp the hexagonal surface at one end of the sleeve 1 and rotate it, so that one end of the connecting tube 4 is tightly connected to the inside of the rubber tube by tapping.
[0027] In this embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, one end of the ferrule 7 is fixedly installed with an annular edge plate, and the two ends of the spring 9 are respectively fixedly connected between the edge plate of the ferrule 7 and the sleeve 1. After one end of the ferrule 7 squeezes the spring 9, the slide groove 701 inside the ferrule 7 will not separate from the positioning slide plate 5. When the hexagonal nut 10 is removed, it is only necessary to squeeze the ferrule 7 in the reverse direction to separate one end of the ferrule 7 from the annular groove 1010 and the clamping groove 1011 on the hexagonal nut 10, so that the hexagonal nut 10 can be rotated again, thereby facilitating the disassembly of the joint.
[0028] Working principle: When the oil pipe joint is in use, first put the round nut 2 on the rubber tube, and at the same time insert the threaded end of the connecting pipe 4 into the inside of the rubber tube, and turn the sleeve 1 clockwise by tapping. During this process, you can use a helper to clamp the hexagonal surface of one end of the sleeve 1 and rotate it, so that one end of the connecting pipe 4 is tightly connected to the inside of the rubber tube by tapping, and then thread the forked thread seat 3 with the tapered thread 101. At this time, the more the forked thread seat 3 is tightened, the more it is affected by the tapered thread 101 and deformed, and the rubber tube is tightly clamped, thereby preventing the sleeve 1 from falling off the rubber tube. At this time, connect the hexagonal nut 10 to the oil pipe threaded joint of the equipment. When the hexagonal nut 10 is threadedly connected to the oil pipe thread head of the equipment, the spring 9 squeezes the ferrule 7 to move in the direction of the hexagonal nut 10. At this time, the groove 701 inside the ferrule 7 slides on the positioning slide 5. When one end of the ferrule 7 and the block 8 fit with one side of the hexagonal nut 10, the orientation of the hexagonal nut 10 is adjusted to make one end of the ferrule 7 and the block 8 insert into the inner sides of the annular groove 1010 and the groove 1011 respectively. At this time, the ferrule 7 cannot be rotated due to the connection structure of the groove 701 and the positioning slide 5, and the groove 1011 on the hexagonal nut 10 is stuck by the block 8. Therefore, when the ferrule 7 cannot be rotated, the hexagonal nut 10 cannot be rotated either, thereby effectively preventing the hexagonal nut 10 from rotating counterclockwise due to vibration generated during the operation of the equipment, and solving the problem of the hexagonal nut 10 loosening and falling off.
[0029] All technical features in this embodiment can be freely combined according to actual needs.
[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
