[0021] The technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment, and in the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it should not be understood as a limitation on the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments.

[0022] As Figure 1 , Figure 2 and Figure 3As shown, the application provides a fastening oil nozzle connector, which comprises a connecting head 1, a connecting ring 2 and a pipe body 3. The connecting head 1 is fixed on the oil nozzle, and the pipe body 3 is connected with the oil pump. In use, the pipe body 3 penetrates through the connecting ring 2, the connecting head 1 extends into the connecting ring 2 and abuts against the pipe body 3, the connecting head 1 is threadedly connected with the connecting ring 2, the connecting head 1 abuts against the pipe body 3, and the pipe body 3 abuts against the connecting ring 2 under the pressure of the connecting head 1, so that the connecting head 1 and the pipe body 3 are finally connected. The oil output by the oil pump enters the connecting head 1 through the pipe body 3 and is finally sprayed out through the oil nozzle. The connecting head 1 and the pipe body 3 are provided with a sealing ring one 4, and the pipe body 3 and the connecting ring 2 are provided with a sealing ring two 5. The sealing ring one 4 and the sealing ring two 5 are deformed under abutment, so as to increase the sealing effect between the connecting head 1 and the pipe body 3 and between the pipe body 3 and the connecting ring 2, and reduce the probability of accidental oil leakage.

[0023] As shown in Figure 2 , Figure 3 and Figure 4 , a ring groove 6 is formed in the inner side of the connecting ring 2 and corresponds to the position between the connecting head 1 and the pipe body 3. The ring groove 6 is provided with a balance port 7 which penetrates to the outside of the connecting ring 2. The balance port 7 is located at the edge of the ring groove 6 away from the connecting head 1 and the pipe body 3. An operating member is arranged in the balance port 7. The operating member comprises a stop block 8, a steel ball 9 and a spring 10. The spring 10 is connected with the steel ball 9 and the stop block 8. In the initial state, the stop block 8 abuts against the pipe body 3 under the action of the spring 10, and the steel ball 9 abuts against the side wall of the balance port 7. At the same time, part of the steel ball 9 extends to the outside of the connecting ring 2. The steel ball 9 blocks the balance port 7, so that dust and water outside cannot enter the ring groove 6 through the balance port 7.

[0024] As shown in Figure 3 and Figure 4 , the stop block 8 has a ring structure, and the stop block 8 is formed with a flow gap 11. Through the gap, the balance port 7 is always in communication with the ring groove 6.

[0025] When the pipe body 3 and the connecting head 1 need to be separated, the spring 10 is pressed to overcome the elastic force of the spring 10, so as to unblock the balance port 7 by the steel ball 9. At this time, the balance port 7 and the ring groove 6 are in communication with the outside. At this time, the connecting ring 2 is rotated by a tool. The threaded connection between the connecting ring 2 and the connecting head 1 is loose, and the degree of compression of the sealing ring one 4 is small. The oil in the connecting head 1 and the pipe body 3 under high pressure flows into the ring groove 6 through the gap between the connecting ring 2, the connecting head 1 and the sealing ring one 4. The original air in the ring groove 6 flows out to the outside through the balance port 7.

[0026] In summary, the oil nozzle connecting piece provided by the embodiment can reduce the probability of oil spraying through the gap between the threads of the connecting ring 2 and the connecting head 1, so that the oil is not easy to pollute and interfere with the equipment and the disassembler, and subsequent disassembly is facilitated.

[0027] The preferred embodiments of the utility model are described above, the protection scope of the utility model is not only limited to the above-mentioned embodiments, and all technical solutions belonging to the utility model idea are within the protection scope of the utility model. It should be noted that for ordinary skilled persons in the art, some improvements and decorations without departing from the principles of the utility model can also be considered as the protection scope of the utility model.
