The provision of the seal 5 helps to further enhance the sealing effect between the first and second bodies 1, 3.

In some embodiments of the invention, the first engagement portion comprises a wave-shaped tooth or a saw-shaped tooth. In this embodiment, the first engaging portion only uses the wave-shaped tooth profile as the connecting structure of the first pipe body 1 and the second pipe body 3, so that the difficulty of the second body rotating relative to the first body when the bent pipe body 4 is adjusted to turn is reduced, and the assembling efficiency of the directional rotary joint assembly can be improved. Of course, saw-shaped teeth are also used as the first meshing part, but the use effect of the wave-shaped teeth is better.

In some embodiments of the present invention, the connecting assembly includes a fixing member 6 and an elastic member 7. Wherein the fixing member 6 is detachably mounted to one of the first pipe body 1 and the second pipe body 3. One end of the elastic member 7 abuts against the fixing member 6, and the other end of the elastic member 7 abuts against the other of the first pipe body 1 and the second pipe body 3. Through setting up coupling assembling into elastic component 7 and mounting 6 to utilize the fixed knot structure that elastic component 7 and the cooperation of mounting 6 formed, not only can be for the sealed packing force that provides of combination of first body 1 and second body 3, ensure that second body 2 and first body are fixed relatively, also guarantee that second body 3 can return naturally behind the direction of rotation.

In the present embodiment, one end of the elastic member 7 abuts on the annular boss 311, and the other end of the elastic member 7 abuts on the fixing member 6. As shown in fig. 6, the fixing member 6 includes a cylinder wall 61, a second mounting plate 62, and a baffle 63. Wherein, one end of the cylinder wall 61 is provided with a second mounting plate 62, and the second mounting plate 62 can be matched with the first mounting plate 111 to form a fixed connection between the fixing element 6 and the first pipe body 1. A baffle 63 is provided at the other end of the cylindrical wall 61, the top end of the elastic member 7 abuts against the lower surface of the baffle 63, and the bottom end of the elastic member 7 abuts against the upper surface of the annular boss 311. Through making one end butt baffle 63 of elastic component 7, other end butt annular boss 311 to based on the effect that resets of elastic component 7, can restrict the displacement of second body 3, the skew phenomenon can not appear when making it rotate the regulation.

In some embodiments of the present invention, the elastic member 7 is sleeved on the outer peripheral surface of the second tube body 3, and the fixing member 6 is sleeved outside the elastic member 7 and fixed on the first tube body 1 by the fastening member 8. Specifically, as shown in fig. 3 and 6, the elastic member 7 is provided as a spring, and the inner diameter of the spring is larger than the outer diameter of the second pipe body 3. In this embodiment, the fixing member 6 is sleeved outside the spring, the fixing member 6 is provided with a second mounting plate 62, the fastening member 8 can be screwed on the first mounting plate 111 through the second mounting plate 62, and the second mounting plate 62 is fixed on the first mounting plate 111. At this time, the elastic member 7 is in a compressed state. Through setting up the elastic component to the spring of a cover in the outside of second body 3, not only can simplify the equipment flow of directional rotary joint subassembly, and can ensure that annular boss 311 receives even external force to the skew condition is difficult for appearing in the realization when turning to the regulation.

It should be noted that the elastic member 7 may have other structures, such as a plurality of springs uniformly arranged around the outer circumferential surface of the second tube 3. However, the spring according to the present embodiment is superior to other types of elastic members in terms of assembly and input.

In some embodiments of the present invention, the fixing member 6 is set to be a sleeve structure, and the cylinder wall 61 of the sleeve structure is provided with an avoiding opening for the bending pipe to pass through the sleeve structure. In the present embodiment, since the bent pipe body 4 is integrally configured with the second body 2, and the elastic member 7 is required to abut against the baffle 63 and the annular boss 311 at the same time, the fixing member 6 is required to pass through the bent pipe body 4 and reach the mounting position. Therefore, as shown in fig. 6, a first avoiding notch 64 is formed in the cylindrical wall 61 of the fixing member 6 so that the bent portion of the bent pipe body 4 can smoothly pass through the fixing member 6. Meanwhile, in order to further facilitate the installation of the fixing member 6, a second avoidance gap 65 is further provided on the cylinder wall 61, and in order to ensure the structural strength of the fixing member 6, the first avoidance gap 64 and the second avoidance gap 65 are symmetrically provided at both ends of the cylinder wall 61. Certainly, mounting 6 can set up to two of mutually supporting, nevertheless compare in setting up mounting 6 to one, and seted up and dodge the opening, and input cost and packaging efficiency all can receive the influence.
