Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings or the orientations or positional relationships that the products of the present invention are conventionally placed in use, and are only used for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
Furthermore, the terms "parallel," "perpendicular," and the like do not require that the components be absolutely parallel or perpendicular, but may be slightly inclined.

The clamping block 121 is located on one side of the clamping groove 120 in the circumferential direction of the connector 100, the clamping jaws 630 are arranged towards one end of the reinforcing member 600, and irregular deformation force can be shared in the circumferential direction of the connector 100, so that acting force between the clamping jaws 630 and the clamping groove 120 is offset mutually by means of the strip-shaped structural characteristics of the reinforcing member 600, and the reinforcing member 600 can be fully attached to the fastening ring 160 and the connector 100 tightly. And the gap that leaves between the both ends of reinforcement 600 can provide certain deformation elasticity space for reinforcement 600 when reinforcement 600 cooperates in connector 100 and fastening ring 160, avoids reinforcement 600 to appear the condition of local uplift.
It should be noted that, when the reinforcement 600 is fitted to the connecting head 100 and the fastening ring 160, the width of the gap left between the two end portions of the reinforcement 600 is smaller than the distance between the two adjacent clamping grooves 120, and further, when the reinforcement 600 is fitted to the connecting head 100 and the fastening ring 160, the width of the gap left between the two end portions of the reinforcement 600 is smaller than half of the distance between the two adjacent clamping grooves 120.
Further, referring to fig. 12, the two ends of the supporting member 400 are provided with guide sections 410, the guide sections 410 are arc-shaped, and one ends of the guide sections 410 far away from the middle of the supporting member 400 are respectively close to the first reference bar 200 and the second reference bar 300. Through this design, when relative slip takes place between support 400 and bellows 500, support 400 can guide bellows 500 to stretch out and draw back better, avoids damaging bellows 500.
In another embodiment of the present invention, if two pipe bodies of the drain pipe are in an up-down position, the first reference rod 200 may be fitted to the upper pipe body, and the second reference rod 300 may be fitted to the lower pipe body, as shown in fig. 13. At this time, the annular flange 180 is disposed on the periphery of the spherical hinge portion 130 engaged with the first reference bar 200, the annular flange 180 is sleeved on the first reference bar 200, the inner diameter of the annular flange 180 is larger than the outer diameter of the first reference bar 200, and the annular flange 180 extends from the spherical hinge portion 130 to the side of the second reference bar 300. The inner diameter of the annular flange 180 is required to be such as not to impede normal deflection of the first extension rod.
Correspondingly, the guide sleeve 310 may be fixedly disposed on the rod body of the second reference rod 300, the guide sleeve 310 is formed by protruding the surface of the second reference rod 300, the guide sleeve 310 extends towards one side away from the first reference rod 200 while protruding towards the surface away from the second reference rod 300, and the guide sleeve 310 is continuously disposed along the circumference of the second reference rod 300 to be in a conical cover shape and shield the spherical hinge portion 130 engaged with the second reference rod 300.
Through the above design, it is possible to effectively prevent sewage from entering the two spherical hinge portions 130, thereby contributing to ensuring the smoothness of the offset of the first reference lever 200 and the second reference lever 300.
In summary, the novel flexible connection device 1000 for the drainage pipe at the bridge expansion joint provided by the embodiment of the invention has the advantages of simple structure, convenience in installation, capability of effectively reducing the probability of structural collapse of the flexible connection part, capability of effectively reducing the probability of problems of loosening, water leakage and the like of the flexible connection part, good use stability, high reliability and positive effect on ensuring the normal work of the drainage system for the bridge expansion joint.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
