The fastening body 100 is supported to ensure that the movable ring 210 provides a locking force for the connection of the pipe 300. The flexible belt 200 and the fastening body 100 jointly form a fastening clamp for the connection of the pipe 300. This alleviates the technical problems in the prior art that the fastening connection of the pipe 300 is relatively troublesome, time-consuming, labor-intensive, and inefficient, and that direct plugging is prone to loosening and leakage.

[0030] On the basis of the above embodiments, further, in a preferred embodiment of the utility model, the fastening body 100 includes a fastening rod 110 and a fastening sleeve 120; the fastening sleeve 120 is sleeved on the outside of the fastening rod 110, and the first limiting channel 111 and the second limiting channel 112 are both arranged between the fastening rod 110 and the fastening sleeve 120, and the first limiting channel 111 and the second limiting channel 112 are respectively arranged on opposite sides of the fastening rod 110.

[0031] In this embodiment, the fastening rod 110 serves as an axial fixing structure, and the fastening sleeve 120 is sleeved on the outside of the fastening rod 110 through one end of the fastening rod 110, and the first limiting channel 111 and the second limiting channel 112 are located between the fastening sleeve 120 and the fastening rod 110. Since the first limiting channel 111 and the second limiting channel 112 both pass through the same end of the fastening rod 110, that is, when the fastening sleeve 120 is sleeved on the outside of the fastening rod 110 along the end, the flexible belt 200 can extend through the end into the first limiting channel 111 and the second limiting channel 112 respectively, and the fastening sleeve 120 can provide a radial clamping force on the flexible belt 200.

[0032] In a preferred embodiment of the present invention, the flexible belt 200 corresponds to the fastening sleeve 120 to form a movable ring 210, and the flexible belt 200 is connected to the fastening rod 110, the fastening rod 110 abuts against the side wall of the pipe 300, and the fastening sleeve 120 can reciprocate relative to the fastening rod 110 in a direction toward or away from the pipe 300, so that the movable ring 210 is fastened to the outside of the pipe 300.

[0033] In this embodiment, after the flexible belt 200 extends into the first limiting channel 111 and the second limiting channel 112 respectively through the inner wall of the fastening sleeve 120, the flexible belt 200 and the fastening rod 110 form a closed movable ring 210. At the same time, when the fastening rod 110 abuts against the side wall of the pipe 300, the tightening effect of the flexible belt 200 is utilized to make the movable ring 210 and the pipe 300 form an annular locking. At this time, the fastening sleeve 120 is moved in the direction toward the pipe 300. The fastening sleeve 120 can apply a radial force to the flexible belt 200, so that the two ends of the flexible belt 200 are clamped in a direction close to each other, so that the movable ring 210 can better provide a tightening force to the pipe 300, thereby ensuring the stability of the pipe 300.

[0035] Optionally, the fastening rod 110 can be a screw, and the fastening sleeve 120 can be a nut. Grooves are provided on both sides of the end of the screw, and the nut is threadedly connected to the screw, forming a first limiting channel 111 and a second limiting channel 112 between the nut and the screw. After the flexible belt 200 passes through the first limiting channel 111 and the second limiting channel 112, the nut is first screwed onto the screw. At this time, the end of the screw is abutted against the side wall of the pipe 300. After the flexible belt 200 is tightened and fixed, the nut is rotated along the direction of the pipe 300 until the nut is completely fitted with the pipe 300. The screw provides an extrusion force to the pipe 300 along its own axial direction, and the movable ring 210 can apply an annular tightening force to the pipe 300. At the same time, the nut ensures the fixation, tightening and support of the flexible belt 200 through the threaded connection of the screw, thereby realizing the tightening of the connection of the pipe 300.

[0036] In addition, there are multiple ways to connect the fastening rod 110 and the fastening sleeve 120. In a preferred embodiment of the present invention, a plurality of limiting grooves are arranged at intervals along the side wall of the fastening rod 110, and elastic protrusions are correspondingly arranged on the inner wall of the fastening sleeve 120. The elastic protrusions can be engaged with any of the limiting grooves to fix the fastening sleeve 120 to the corresponding position of the fastening rod 110.

[0037] In this embodiment, a plurality of limiting grooves are provided at intervals on the side wall along the axis of the fastening rod 110, and an elastic protrusion is provided on the inner wall of the fastening sleeve 120. The elastic protrusion can be separated from the limiting groove by applying a force in the radial direction of the fastening rod 110. At the same time, when the elastic protrusion is engaged with any limiting groove, it can ensure the fixing requirements of the connection between the fastening rod 110 and the fastening sleeve 120; a first limiting channel 111 and a second limiting channel 112 are formed between the fastening sleeve 120 and the fastening rod 110. After the flexible belt 200 passes through the first limiting channel 111 and the second limiting channel 112, the fastening sleeve 120 is first connected and fixed with the limiting groove of the fixing rod in a direction away from the pipe 300. At this time, the end of the fastening rod 110 is abutted against the side wall of the pipe 300, and after the flexible belt 200 is tightened and fixed, the fastening sleeve 120 is moved along the direction of the pipe 300 until the fastening sleeve 120 is completely fitted with the pipe 300. At this time, the fastening sleeve 120 can form a snap connection with the limiting groove at the corresponding position through the elastic protrusion, and the fastening rod 110 provides an extrusion force on the pipe 300 along its own axial direction. The movable ring 210 can apply an annular fastening force to the pipe 300. At the same time, the fastening sleeve 120 ensures the fixation, tightening and support of the flexible belt 200 through the elastic snap connection of the fastening rod 110, thereby realizing the fastening of the connection of the pipe 300.

[0038] In a preferred embodiment of the present invention, a side wall of the limiting groove close to the pipe 300 is provided with an inclined chamfer, and the fastening sleeve 120 can move along the inclined chamfer toward the pipe 300 through the elastic protrusion.

[0039] In this embodiment, by utilizing the inclined chamfer in the limiting groove, the fastening sleeve 120 can be conveniently moved in the direction toward the pipe 300. As long as the fastening sleeve 120 is squeezed hard, the elastic protrusion will retract under the action of the inclined chamfer, thereby facilitating the unidirectional movement of the fastening sleeve 120. On the contrary, when the fastening sleeve 120 moves in the direction away from the pipe 300, the elastic protrusion will form a snap connection with the side wall of the limiting groove, thereby ensuring the stability of the connection between the fastening sleeve 120 and the fastening rod 110.

[0040] In a preferred embodiment of the present invention, one end of the fastening rod 110 corresponding to the pipe 300 has a clamping groove, and the fastening rod 110 is clamped on the outside of the pipe 300 through the clamping groove.

The fixing hole 113 is respectively connected to the first limiting channel 111 and the second limiting channel 112, and the flexible belt 200 is connected to the fastening rod 110 through the fixing hole 113.

[0043] In this embodiment, the fixing hole 113 penetrates along the radial direction of the fastening rod 110, and the fixing hole 113 serves as the end focus of the first limiting channel 111 and the second limiting channel 112. When the flexible belt 200 extends into the first limiting channel 111 and the second limiting channel 112 through the end of the fixing rod, in order to facilitate the connection of the two free ends of the flexible belt 200, by passing one of the free ends of the flexible belt 200 through the fixing hole 113, the two ends of the flexible belt 200 can be wrapped and fixed together, which is convenient for tightening and fixing the movable ring 210.

[0044] In a preferred embodiment of the present invention, the flexible belt 200 includes a metal wire, one end of the metal wire passes through the fixing hole 113 and is connected to the other end.

[0045] Optionally, the flexible belt 200 can be made of steel wire or iron wire, etc., taking advantage of the flexible winding and tight locking properties of the metal wire. That is, when the movable ring 210 formed by the flexible belt 200 is sleeved on the outside of the pipe 300, a cross closed port can be formed by rotation, so as to form a complete closed loop of the movable ring 210, which can better ensure the tight clamping of the pipe 300.

[0046] In a preferred embodiment of the present invention, one end of the fastening rod 110 away from the fastening sleeve 120 has a connecting protrusion, and both ends of the flexible belt 200 are fixedly connected to the connecting protrusion respectively.

[0047] In this embodiment, the connecting protrusion can be set at the end of the fastening rod 110 close to the end away from the pipe 300. The connecting protrusion can be radially extended along the side wall of the fastening rod 110, which can better facilitate the fastening or winding and fixing of the flexible belt 200, making it easier for the staff to operate.
