[0011] In the diagram, 1. Corrugated body; 2. Connector body; 3. Movable ring; 4. Limiting ring; 5. Connecting rod; 6. Snap ring; 7. Spring; 8. Movable cap. Detailed Implementation
[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0013] like Figure 1 As shown, this corrugated pipe includes a corrugated body 1 and a connector body 2 connected to the corrugated body 1. A movable ring 3 is provided on the outer peripheral wall of the connector body 2, which slides and engages with it. Limiting units are provided on the outer peripheral walls of the connector body 2 at both ends, which are connected to and restrict the position of the movable ring 3. Connecting units are provided on the movable ring 3, which are connected to and can be connected to other structures. Through these connecting units, the corrugated pipe is suspended at the connection point, facilitating assembly. The limiting unit includes two limiting rings 4 connected to the connector body 2. The outer diameter of the movable ring 3 is larger than the outer diameter of the limiting rings 4. The connecting unit includes a flexible connecting rod 5 connected to the movable ring 3 and a retaining ring 6 connected to the connecting rod 5, facilitating connection to other structures. The connecting rod 5 is located outside the limiting rings 4. The retaining ring 6 can also be a hook or a snap-fit structure, depending on actual needs. The other structures mentioned above need to be compatible with the corrugated pipe itself. To prevent the connecting unit from malfunctioning, the number of connecting rods 5 can be set according to actual needs. The connector body 2 is equipped with a movable unit that is movably connected to it and used to restrict the movement of the movable ring 3. This movable unit includes a spring 7 and a movable cap 8. The spring 7 is sleeved on and connected to the connector body 2, and its two ends respectively abut against the corresponding limiting ring 4 and movable ring 3. The movable cap 8 is set on and movably connected to the connector body 2. A handle can be provided on the movable cap 8 to facilitate its movement. The movable cap 8 controls the contact between the movable ring 3 and the spring 7. When the orientation of the connecting rod 5 needs to be adjusted, the movable cap 8 is loosened to reduce the contact force between the movable ring 3 and the spring 7, thereby rotating the movable cap 8 to allow for a certain degree of orientation change. After adjustment, the movable cap 8 can be used to limit the movement of the movable ring 3, while ensuring the service life of the spring 7.
[0014] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0015] Although the same terms are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for the convenience of describing and explaining the essence of the present application; it is contrary to the spirit of the present application to interpret them as any kind of additional limitation.
