The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and therefore only serve as examples, and cannot limit the protection scope of the utility model.

[0023] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be the usual meaning understood by the technical personnel in the field to which the utility model belongs.

[0024] Referring to Figures 1-3 , the anti-twist pipe locking connector comprises:

[0025] The locking connector main body 1 is provided with threaded connecting ends at both ends;

[0026] The threaded connecting ends are provided with a first threaded connector 2 and a second threaded connector 3, and the second threaded connector 3 is provided with a connecting pipe 4 extending on the locking connector main body 1; and

[0027] The second threaded connector 3 is provided with a matching locking nut 5, the connecting pipe 4 is sequentially provided with uniformly distributed first anti-skid teeth 6 and uniformly distributed second anti-skid teeth 7 in the length direction of the pipe face, and gaps are provided between the locking nut 5 and the first anti-skid teeth 6 and the second anti-skid teeth 7.

[0028] By providing the threaded connecting ends on the locking connector main body 1, the connection of the pipeline is realized. Specifically, since the threaded connecting ends are provided with the first threaded connector 2 and the second threaded connector 3, and the connecting pipe 4 extending on the locking connector main body 1 is arranged at the second threaded connector 3, the external air pipe is connected with the connecting pipe 4, and the air pipe is locked by the threaded connection between the locking nut 5 and the second threaded connector 3. At the same time, since the connecting pipe 4 is sequentially provided with uniformly distributed first anti-skid teeth 6 and uniformly distributed second anti-skid teeth 7 in the length direction of the pipe face, the connecting pipe 4 is connected with the connecting pipe 4 by the first anti-skid teeth 6 and the second anti-skid teeth 7, which not only ensures the sealing of the air pipe to be connected, but also provides good friction force to prevent the air pipe from sliding radially, thereby preventing the air pipe from being twisted with the locking nut 5.

[0029] Preferably, the locking connector main body 1 is provided with a fixed force nut sleeve 8 on the circumferential side surface.

[0030] With reference to the display in Figure 1 , a force nut sleeve 8 is arranged on the locking connector body 1, which is conducive to the connection of the trachea or the connection between the locking nut 5 and the locking connector body 1. Optionally, the force nut sleeve 8 is fixedly connected to the locking connector body 1, and in the fixed connection arrangement, the force nut sleeve 8 and the locking connector body 1 are integrally arranged.

[0031] As a preferred, the diameter of the connecting pipe 4 is smaller than the diameter of the second threaded connector 3 at the central axis position of the second threaded connector 3.

[0032] The connecting pipe 4 is arranged on one side of the second threaded connector 3, so that the locking connector body 1 has a terminal for connecting with the external trachea. Specifically, the connecting pipe 4 is arranged at the central axis position of the second threaded connector 3, and the diameter of the connecting pipe 4 is smaller than the diameter of the second threaded connector 3. Thus, the external trachea can be sleeved on the connecting pipe 4, and the second threaded connector 3 can pass through the external trachea and the connecting pipe 4 and be threadedly connected with the locking nut 5. Thus, the inner wall of the locking nut 5 and the connecting pipe 4 can be relatively tightly fixed to the trachea on the connecting pipe 4.

[0033] As a preferred, the connecting pipe 4 includes a main pipe body 9 and a tapered connecting end 10 arranged at the end of the main pipe body 9. The first anti-skid teeth 6 are distributed on the length direction of the main pipe body 9, and the length of the first anti-skid teeth 6 is the same as that of the main pipe body 9.

[0034] In order to better connect the connecting pipe 4 with the external trachea to be connected, the connecting pipe 4 is composed of the main pipe body 9 and the tapered connecting end 10. The first anti-skid teeth 6 are distributed on the length direction of the main pipe body 9, and the length of the first anti-skid teeth 6 is the same as that of the main pipe body 9. Thus, the external trachea sleeved on the connecting pipe 4 can be relatively sleeved on the first anti-skid teeth 6.

[0035] As a preferred, the second anti-skid teeth 7 are arranged at the position close to the main pipe body 9 of the tapered connecting end 10, and the circumferential diameter formed by the plurality of first anti-skid teeth 6 is the same as the circumferential diameter formed by the plurality of second anti-skid teeth 7.

[0036] Based on the basis of distributing the first anti-skid teeth 6 on the side of the groove of the length direction of the main pipe body 9, the second anti-skid teeth 7 are arranged on the taper connecting end 10, and the taper connecting end 10 is located at the position close to the main pipe body 9, and then, through the cooperation between the first anti-skid teeth 6 and the second anti-skid teeth 7, the external trachea can be more stably sleeved on the connecting pipe 4.

[0037] As a preferred mode of the embodiment, the spacing between the plurality of first anti-skid teeth 6 is greater than the spacing between the plurality of second anti-skid teeth 7.

[0038] As preferred, the outer diameter of the locking nut 5 is greater than the outer diameter of the force receiving nut sleeve 8.

[0039] Through the setting in this way, it is more convenient to relatively rotate the locking nut 5 with the locking connector body 1 through the clamping force receiving device, and then relatively threadedly connected, so that better force receiving rotation is realized.

[0040] As preferred, the end of the internal thread in the locking nut 5 is provided with a limiting groove 11.

[0041] It can be understood that by providing the limiting groove 11 at the end of the internal thread in the locking nut 5, the relative sleeving installation position can be maintained after the thread connection between the locking nut 5 and the second threaded connector 3.

[0042] The working principle and working process of the utility model:

[0043] The anti-twist pipe locking connector provided by the utility model is used, the trachea to be connected is connected with the connecting pipe 4 at the center axis position of the second threaded connector 3, at this time, the external trachea is sleeved on the connecting pipe 4, the second threaded connector 3 passes through the external trachea and the connecting pipe 4, and is threadedly connected with the locking nut 5, so that the inner wall of the locking nut 5 and the connecting pipe 4 can be relatively tightly fixed and arranged on the trachea on the connecting pipe 4.

[0044] Since the threaded connection end is provided with the first threaded connector 2 and the second threaded connector 3, and the connecting pipe 4 extending on the locking connector body 1 is arranged at the second threaded connector 3, thus realizing the locking of the external air pipe through the connection with the connecting pipe 4, and the locking of the air pipe through the direct threaded connection of the locking nut 5 and the second threaded connector 3; at the same time, since the first anti-skid teeth 6 and the second anti-skid teeth 7 are arranged in turn on the connecting pipe 4 in the length direction of the pipe surface, the connecting pipe 4 is connected with the connecting pipe 4 through the first anti-skid teeth 6 and the second anti-skid teeth 7, which not only ensures the sealing of the air pipe to be connected, but also provides good friction force to ensure that the air pipe cannot slide radially, so as to prevent the air pipe from twisting with the locking nut 5.
