[0002] At present, for the water supply and drainage pipelines in buildings, a connecting sleeve is generally used for connection, and glue is used for fastening and sealing. This connection structure has the advantages of simplicity and low cost, but there are still some disadvantages: due to the influence of time, the glue is prone to embrittlement, and combined with the settlement factor of the building itself, etc., when the pipelines are pulled, the glued part is prone to cracking, resulting in damaged sealing performance. Therefore, it can be seen that there is still room for improvement in the current technology. In view of this, the utility model provides a water supply and drainage pipeline connection structure to better realize the connection of the current water supply and drainage pipelines.

[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present utility model in conjunction with the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0026] Furthermore, the present utility model is described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, the three-dimensional spatial dimensions of length, width and depth should be included.

[0027] Referring to Figures 1-5 , an embodiment of the present utility model provides a water supply and drainage pipe connection structure for connecting the pipe body 1 of the water supply and drainage pipe. At the same time, in order to cooperate with the use of the present utility model, a convex ring 2 needs to be fixedly arranged in a circle on the circumferential surface at the port of the pipe body 1. The present utility model includes the following parts:

[0028] A sleeve 3, which is used to accommodate the pipe body 1. In actual production, the inner diameter of the sleeve 3 is slightly larger than the maximum diameter of the convex ring 2, so as to ensure that the pipe body 1 can extend into the sleeve 3;

[0029] A first flexible pad 4 and a second flexible pad 5. The first flexible pad 4 is annular and is attached to the inside of the sleeve 3; the second flexible pad 5 is arranged on the side of the sleeve 3. Both of them are provided with a hollow inside, and the two hollow parts are kept in communication;

[0030] A holding portion 6 is movably arranged on the peripheral side of the sleeve 3, the second flexible pad 5 is located between the outer peripheral wall of the sleeve 3 and the holding portion 6, and a limiting end 7 is constructed on the holding portion 6, which is used to resist the convex ring 2, so as to achieve a limiting effect;

[0031] The fastening assembly 8 is used to enable the sleeve 3 and the pressing portion 6 to maintain relative movement through the fastening assembly 8;

[0032] According to the above part, if Figure 5 As shown, when the utility model is in use, the ends of the two tube bodies 1 to be connected extend into the sleeve 3, and the holding part 6 is moved on the sleeve 3 through the fastening assembly 8, and the holding part 6 cooperates with the peripheral side of the sleeve 3 to squeeze the second flexible pad 5, so that the internal air is squeezed into the first flexible pad 4, and the first flexible pad 4 expands and thickens, thereby simultaneously tightening the peripheral surfaces of the two tube bodies 1 to achieve a sealed docking effect between the two tube bodies 1. At the same time, when the holding part 6 is active, the limiting end 7 moves to one side of the convex ring 2, thereby limiting the convex ring 2, so that the tube body 1 cannot be separated from the inside of the sleeve 3, thereby simultaneously achieving a locking effect between the two tube bodies 1, making it impossible to separate;

[0033] Compared with the prior art, the utility model has flexibility in the flexible pad itself. Even if the two tube bodies 1 form a slight relative movement at the joint, the first flexible pad 4 can be adaptively adjusted, so that when resisting deformation, the two tube bodies 1 can still maintain a good sealing effect. At the same time, when connecting the two tube bodies 1, the utility model relies on the mutual interference between the limit end 7 and the convex ring 2, which has a better locking effect than the adhesive method; in the utility model, the first flexible pad 4 and the second flexible pad 5 can both be made of silicone, such as the sleeve 3 and the holding part 6 can be made of a material with stronger rigidity, such as steel or alloy.

[0034] Further, see Figure 3 The first flexible pad 4 and the second flexible pad 5 are connected as one piece, and the one-piece connection makes the stability and firmness between the two better.

[0035] Further, see Figures 1-3 and Figure 5 There are two pressing parts 6, which are symmetrically distributed around the sleeve 3. There are also two second flexible pads 5, which are consistent with the distribution of the two pressing parts 6. Therefore, when the pressing part 6 is moved on the sleeve 3, it can be achieved by adjusting the distance between the two pressing parts 6, so that the movement of the two pressing parts 6 relative to the sleeve 3 is synchronously achieved. At the same time, the setting of the two second flexible pads 5 makes the inflation effect of the first flexible pad 4 tighter and more effective.

[0036] Further, see Figure 1 and Figure 2 The fastening assembly 8 includes a stud 801, which is threadedly matched with the two pressing parts 6 respectively, so that when the stud 801 is rotated, the distance between the two pressing parts 6 can be tightened or enlarged, making the adjustment process simple and convenient, thereby facilitating use.

[0037] Further, see Figure 1 A rotational cooperation relationship is also established between the stud 801 and the sleeve 3, so that the position of the stud 801 on the sleeve 3 remains unchanged, and the two pressing parts 6 always form a symmetrical relationship with respect to the sleeve 3 when moving, so that the pressing effect on the two second flexible pads 5 remains uniform and consistent, making the inflation process more uniform and stable.

[0038] Further, see Figure 1 , Figure 2 and Figure 5 The length of the sleeve 3 is greater than the length between the two limit ends 7 on the holding portion 6, and an avoidance hole 9 is constructed on the sleeve 3, so that the limit end 7 is always located in the avoidance hole 9 when it is moving. The cooperation of the avoidance hole 9 can provide force protection for the limit end 7 to prevent the limit end 7 from being crushed or deformed when the tube body 1 is subjected to a large escape force on the sleeve 3. Therefore, the cooperation of the avoidance hole 9 can improve the overall locking effect of the utility model on the tube body 1.

[0039] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
