[0018] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in conjunction with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0019] According to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes a tubing nipple that is convenient to install, including a tubing nipple main body 1, a connecting pipe 2, and a clamp 3. One end of the tubing nipple main body 1 is provided with a connecting pipe 2, and a clamp 3 is provided between the tubing nipple main body 1 and the connecting pipe 2. The clamp 3 is provided with a clamping mechanism, and one end of the tubing nipple main body 1 adjacent to the connecting pipe 2 is provided with a clamping mechanism. First, the tubing nipple main body 1 and the connecting pipe 2 are initially fixed together through the clamping mechanism, and then the clamp 3 is sleeved on the connection between the tubing nipple main body 1 and the connecting pipe 2. The clamping mechanism is used to clamp the connection between the tubing nipple main body 1 and the connecting pipe 2, so that the tubing nipple main body 1 and the connecting pipe 2 are completely fixed together, and the installation process is convenient.

[0020] The clamping mechanism includes an insertion block 4, a slot 5, an annular groove 6, and a connecting ring 7. Symmetrically fixed to one end of the tubing nipple main body 1 are insertion blocks 4. Symmetrically opened at one end of the connecting pipe 2 are slots 5. The tubing nipple main body 1 is snap-connected to the connecting pipe 2 through the insertion blocks 4. Both the insertion blocks 4 and one end of the connecting pipe 2 are provided with annular grooves 6. Inside the annular grooves 6 is a connecting ring 7. The material of the connecting ring 7 is rubber, and the thickness of the connecting ring 7 is equal to that of the annular groove 6. The diameter of one end of the tubing nipple main body 1 is equal to that of the connecting pipe 2. Insert the insertion blocks 4 along the inner wall of the slot 5 into the inside of one end of the connecting pipe 2. Then, expand the connecting ring 7 and sleeve it on the outside of the connecting pipe 2. Push the connecting ring 7 into the inside of the annular groove 6. The connecting ring 7 contracts inward due to its own elasticity, and the insertion blocks 4 and one end of the connecting pipe 2 are clamped by the connecting ring 7, initially fixing the tubing nipple main body 1 and the connecting pipe 2 together, which is more convenient than aligning the flange plates and then sequentially screwing in multiple connecting bolts.

[0021] The clamping mechanism includes a fixing ring 8, a screw hole 10 and a fastening bolt 11. A fixing ring 8 is provided inside the clamp 3. A screw hole 10 is provided at the top of the clamp 3. The screw hole 10 is internally threaded with a fastening bolt 11. The material of the fixing ring 8 is set as an elastic reed. A plurality of clamping teeth 9 are equidistantly distributed in a circular shape on the inner side of the fixing ring 8. The inner diameter of the clamping teeth 9 is equal to the diameter of the connecting pipe 2. The clamp 3 is sleeved at the connection between the oil pipe nipple main body 1 and the connecting pipe 2. The clamping teeth 9 on the inner side of the fixing ring 8 are in contact with the outer walls of the oil pipe nipple main body 1 and one end of the connecting pipe 2. The clamping teeth 9 can increase the friction with the oil pipe nipple main body 1 and one end of the connecting pipe 2. Turn the fastening bolt 11 to move inward into the screw hole 10. The fastening bolt 11 drives the two sides at the top of the clamp 3 to approach each other, so as to drive the clamp 3 to contract inward. The clamp 3 clamps the connection between the oil pipe nipple main body 1 and the connecting pipe 2 through the clamping teeth 9, so that the oil pipe nipple main body 1 and the connecting pipe 2 are completely fixed together.

[0022] Both ends of the oil pipe nipple main body 1 and the connecting pipe 2 are symmetrically and fixedly connected with limit blocks 12. Both ends of the oil pipe nipple main body 1 and the connecting pipe 2 are sleeved with positioning rings 13. A compensation mechanism is provided between the two positioning rings 13. The compensation mechanism includes a connecting ear 14 and a threaded rod 15. Connecting ears 14 are symmetrically and fixedly connected to both sides of the positioning ring 13. A threaded rod 15 is penetrated between the front and rear parallel connecting ears 14. Nuts are symmetrically threaded at both ends of the threaded rod 15. The two positioning rings 13 are respectively sleeved on the oil pipe nipple main body 1 and the connecting pipe 2, and are fitted on the outside of the limit blocks 12. The threaded rod 15 is inserted into the connecting ear 14 and penetrates out of the connecting ear 14 in front of it. Nuts are tightened at both ends of the threaded rod 15 to clamp the positioning ring 13 with the nuts. At this time, it can drive the oil pipe nipple main body 1 and the connecting pipe 2 to approach each other, avoiding the increase of the gap between the oil pipe nipple main body 1 and the connecting pipe 2 during long-term use and weakening its sealing performance.

[0023] For this oil pipe nipple, insert the insertion block 4 into the inside of one end of the connecting pipe 2 along the inner wall of the slot 5. Then expand the connecting ring 7 and sleeve it on the outside of the connecting pipe 2. Push the connecting ring 7 into the inside of the annular groove 6. The connecting ring 7 contracts inward by its own elastic force. The connecting ring 7 clamps the insertion block 4 and one end of the connecting pipe 2 to initially fix the oil pipe nipple main body 1 and the connecting pipe 2 together. The clamp 3 is sleeved at the connection between the oil pipe nipple main body 1 and the connecting pipe 2. Turn the fastening bolt 11 to move inward into the screw hole 10. The fastening bolt 11 drives the two sides at the top of the clamp 3 to approach each other, so as to drive the clamp 3 to contract inward. The clamp 3 clamps the connection between the oil pipe nipple main body 1 and the connecting pipe 2 through the clamping teeth 9, so that the oil pipe nipple main body 1 and the connecting pipe 2 are completely fixed together.
