The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
In the description of the present application, it should be noted that, directions or positional relationships indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are directions or positional relationships based on those shown in the drawings, or are directions or positional relationships conventionally put in use of the inventive product, are merely for convenience of describing the present application and simplifying the description, and are not indicative or implying that the apparatus or element to be referred to must have a specific direction, be constructed and operated in a specific direction, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
Furthermore, the terms "parallel," "perpendicular," and the like, do not denote that the components are required to be absolutely parallel or perpendicular, but may be slightly inclined. For example, "parallel" merely means that the directions are more parallel than "perpendicular" and does not mean that the structures must be perfectly parallel, but may be slightly tilted.
Furthermore, the terms "horizontal," "vertical," "overhang," and the like do not denote a requirement that the component be absolutely horizontal or overhang, but rather may be slightly inclined.

The terms "substantially," "essentially," and the like are intended to be interpreted as referring to the fact that the term is not necessarily to be construed as requiring absolute accuracy, but rather as a deviation. For example: the term "substantially equal to" does not merely mean absolute equality, but is difficult to achieve in actual production and operation, and generally has a certain deviation. Thus, in addition to absolute equality, "approximately equal to" includes the above-described case where there is a certain deviation. In other cases, the terms "substantially", "essentially" and the like are used in a similar manner to those described above unless otherwise indicated.

Through the above design, can strengthen the cooperation compactness of reinforcement 600 with connector 100, clamping ring 160 effectively, two sealing pads 640 respectively with the outside of clamping ring 160, the outside laminating of connector 100, sealing strip 650 can further be with the gap shutoff between clamping ring 160 and the connector 100, further improves structure seal effect and stability.
In addition, in the embodiment, the clamping block 121 is located at one side of the clamping groove 120 along the circumferential direction of the connector 100, and the clamping claws 630 are all disposed toward one end of the reinforcement member 600. Since the force between the claw 630 and the clamping groove 120 is mainly concentrated between the abutting surfaces of the clamping teeth 632 and the clamping block 121 and between the abutting surfaces of the base post 631 and the side wall of the clamping groove 120, irregular deformation may occur after interference fit between the claw 630 and the clamping groove 120. The clamping blocks 121 are located on one side of the clamping grooves 120 along the circumferential direction of the connector 100, the clamping claws 630 are arranged towards one end of the reinforcing member 600, and the irregular deformation force can be distributed along the circumferential direction of the connector 100, so that acting forces between the clamping claws 630 and the clamping grooves 120 are mutually offset by means of the strip-shaped structural characteristics of the reinforcing member 600, and the reinforcing member 600 is guaranteed to be fully tightly attached to the fastening ring 160 and the connector 100. The gap left between the two ends of the reinforcement member 600 when the reinforcement member 600 is engaged with the connector 100 and the fastening ring 160 can provide a certain deformation elastic space for the reinforcement member 600, so as to avoid the situation of local bulge of the reinforcement member 600.
It should be noted that, when the reinforcement member 600 is mated with the connector 100 and the fastening ring 160, the width of the gap left between the two ends of the reinforcement member 600 is smaller than the distance between the two adjacent clamping grooves 120, and further, when the reinforcement member 600 is mated with the connector 100 and the fastening ring 160, the width of the gap left between the two ends of the reinforcement member 600 is smaller than half the distance between the two adjacent clamping grooves 120.
Further, referring to fig. 12, both ends of the support 400 are provided with guide sections 410, the guide sections 410 are arc-shaped, and one ends of the guide sections 410 away from the middle of the support 400 are close to the first reference bar 200 and the second reference bar 300, respectively. By this design, when the relative sliding occurs between the support 400 and the bellows 500, the support 400 can better guide the bellows 500 to expand and contract, avoiding damaging the bellows 500.
In other embodiments of the present application, if the two pipes of the drain pipe are in a vertical positional relationship, the first reference bar 200 may be coupled to the upper pipe, and the second reference bar 300 may be coupled to the lower pipe, as shown in fig. 13. At this time, the circumferential edge of the ball hinge 130 engaged with the first reference bar 200 is provided with an annular flange 180, 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 ball hinge 130 toward the second reference bar 300. The inner diameter of the annular flange 180 is required to be such that normal deflection of the first extension rod is not impeded.
Correspondingly, the rod body of the second reference rod 300 may be fixedly provided with a guide cover 310, the guide cover 310 is formed by protruding the surface of the second reference rod 300, the guide cover 310 protrudes towards the surface far away from the second reference rod 300 and extends towards one side far away from the first reference rod 200, and the guide cover 310 is continuously provided with a conical cover shape along the circumferential direction of the second reference rod 300 and shields the spherical hinge part 130 matched with the second reference rod 300.
With the above design, it is possible to effectively prevent sewage from entering the two ball hinge parts 130, thereby helping to ensure 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 application has the advantages of simple structure and convenient installation, can effectively reduce the probability of structural collapse of the flexible connection part, can effectively reduce the probability of loosening, water leakage and other problems of the flexible connection part, has good use stability and high reliability, and has positive effects on guaranteeing the normal operation of a drainage system of the bridge expansion joint.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
