[0047] Example

[0048] Reference Figures 1 to 4In this embodiment, to address the issue of connection displacement or pipe deformation caused by rigid pipe connections in the prior art, this utility model provides a rubber expansion joint 1 connection structure, including: an expansion joint 1, a first connecting component 3, a second connecting component 5, and a locking component. The expansion joint 1 is made of rubber and is sleeve-shaped. Both ends of the expansion joint 1 are provided with first connecting members 11, and both ends of the expansion joint 1 are respectively fitted with second connecting members 12. The two second connecting members 12 are located between the two first connecting members 11, and each of the two second connecting members 12 abuts against one side of a first connecting member 11. That is, each end of the expansion joint 1 has one first connecting member 11 and one second connecting member 12, facilitating subsequent alignment and connection of the expansion joint 1 with the first connecting component 3 and the second connecting component 5. The first connecting component 3 is located at one end of the expansion joint 1, with one end connected to the expansion joint 1 and the other end connected to a pipe. The second connecting component 5 is disposed at the other end of the expansion joint 1. One end of the second connecting component 5 is connected to the expansion joint 1, and the other end is connected to another pipe. That is, the expansion joint 1 is connected to two pipes that need to be connected via the first connecting component 3 and the second connecting component 5, respectively, to allow normal flow between the two pipes. Multiple locking components are respectively disposed on the first connecting component 3 and the second connecting component 5. The first connecting component 3 is locked to one end of the expansion joint 1 via the multiple locking components, and the second connecting component 5 is locked to the other end of the expansion joint 1 via the multiple locking components. That is, the first connecting component 3 and the second connecting component 5 are connected to both ends of the expansion joint 1 via the multiple locking components. In this embodiment, since the two pipes that need to be connected are connected as a whole by an expansion joint 1 through a first connecting component 3 and a second connecting component 5, the two pipes that need to be connected are flexibly connected by the expansion joint 1. Therefore, in order to ensure the stability of the connection between the two pipes, the expansion joint 1 structure further includes: a plurality of limiting connecting components 2. The plurality of limiting connecting components 2 are disposed on the outside of the expansion joint 1. The first connecting component 3 and the second connecting component 5 are respectively located at both ends of the plurality of limiting connecting components 2. The outer sides of the first connecting component 3 and the second connecting component 5 are respectively limited and connected to the plurality of limiting connecting components 2 by the plurality of locking components.In this embodiment, the two pipes that need to be connected are flexibly connected together by an expansion joint 1 through a first connecting component 3 and a second connecting component 5, which satisfies the connection requirements between the pipes and avoids the situation where the connection is easily displaced or the pipe is deformed during use. At the same time, multiple limiting connecting components 2 are provided on the outside of the expansion joint 1 to prevent the expansion joint 1 from deforming excessively, which could cause the connection to be easily displaced or the pipe to deform during use.

[0049] Reference Figure 1 and Figure 2In this embodiment, the first connecting component 3 and the second connecting component 5 have the same structure. The first connecting component 3 and the second connecting component 5 are respectively disposed at both ends of the expansion joint 1, and the first connecting component 3 and the second connecting component 5 are symmetrically arranged at both ends of the expansion joint 1. Specifically, the first connecting component 3 is described as an example. The first connecting component 3 includes a third connecting member 31 and a mating sleeve 32. The third connecting member 31 is annular and is disposed on one end of the expansion joint 1, and the third connecting member 31 fits against the first connecting member 11. In order to ensure the stability of the connection between one end of the expansion joint 1 and the pipeline through the first connecting component 3, the first connecting member 11, the second connecting member 12, and the third connecting member 31 are all provided with a plurality of locking holes. The plurality of locking holes on the first connecting member 11, the second connecting member 12, and the third connecting member 31 are aligned one by one, so that the locking component can lock the first connecting member 11, the second connecting member 12, and the third connecting member 31 as a whole through the plurality of locking holes (not shown in the figure). One end of the mating sleeve 32 is located on the third connecting member 31 away from the expansion joint 1. One end of the mating sleeve 32 is connected to the third connecting member 31, and the other end of the mating sleeve 32 is connected to a pipe, so that one end of the expansion joint 1 is connected to a pipe through the mating sleeve 32, the first connecting member 11, the second connecting member 12, and the third connecting member 31. That is, one end of the expansion joint 1 is connected to the mating sleeve 32 on the third connecting member 31 through the first connecting member 11, the second connecting member 12, and then the mating sleeve 32 is connected to a pipe, so that the expansion joint 1 is connected to the pipe. Similarly, the second connecting assembly 5 also includes a third connecting member 31 and a mating sleeve 32. The third connecting member 31 on the second connecting assembly 5 abuts against and fits against the first connecting member 11 on the other end of the expansion joint 1, while the mating sleeve 32 on the second connecting assembly 5 is connected to another pipe, so that the two ends of the expansion joint 1 are connected to two pipes that need to be connected through the mating sleeves 32 in the first connecting assembly 3 and the second connecting assembly 5, respectively. In this embodiment, in order to ensure the connection between the docking sleeve 32 and the two pipes that need to be connected, the docking sleeve 32 is in the shape of a conical opening. The large opening of the docking sleeve 32 is close to the expansion joint 1, and the small opening of the docking sleeve 32 is located inside the pipe, so as to facilitate the alignment and connection of the docking sleeve 32 and the pipe.

[0050] Reference Figure 1 and Figure 4In this embodiment, multiple locking components are respectively disposed at both ends of the expansion joint 1. These multiple locking components sequentially pass through the third connecting member 31, the first connecting member 11, and the second connecting member 12, respectively connecting and locking the first connecting member 3 and the second connecting member 5 to both ends of the expansion joint 1. For ease of description, one locking component is used as an example. Specifically, the locking component includes: a second connecting rod 4 and two locking nuts 41. The second connecting rod 4 passes through the third connecting member 31, the first connecting member 11, and the second connecting member 12 sequentially via locking holes. The multiple second connecting rods 4 are used to lock the first connecting member 3 and the second connecting member 5 to both ends of the expansion joint 1, respectively. The two locking nuts 41 are threadedly connected to both ends of the second connecting rod 4. One locking nut 41 abuts against the end of the second connecting member 12 away from the expansion joint 1, and the other locking nut 41 abuts against the end of the third connecting member 31 away from the expansion joint 1. The third connector 31, the first connector 11, and the second connector 12 are positioned between two locking nuts 41. The two locking nuts 41 are used to lock the third connector 31, the first connector 11, and the second connector 12 together, so that the two ends of the expansion joint 1 are connected to the first connecting component 3 and the second connecting component 5 respectively. In this embodiment, to ensure the locking effect of the two locking nuts 41, the locking assembly further includes two snap-fit ​​plates 42, each with a snap-fit ​​protrusion 421 on one side. Both snap-fit ​​plates 42 are sleeved on the second connecting rod 4. One snap-fit ​​plate 42 is positioned between the locking nut 41 and the third connecting member 31, with the snap-fit ​​protrusion 421 snapping into the third connecting member 31. The other snap-fit ​​plate 42 is positioned between the locking nut 41 and the second connecting member 12, with the snap-fit ​​protrusion 421 snapping into the second connecting member 12. This allows the snap-fit ​​protrusion 421 on the snap-fit ​​plate 42 to cooperate with the locking nut 41 to limit and lock the positions of the first connecting member 11, the second connecting member 12, and the third connecting member 31. Preferably, in this embodiment, the second connecting rod 4 is a screw.

[0051] Reference Figure 1 , Figure 2 and Figure 3To ensure the stability of the connection between two pipes that need to be connected, two or more limiting connection components 2 can be provided on the outside of the expansion joint 1. These limiting connection components 2 cooperate with the deformation of the expansion joint 1 to provide support and ensure the stability of the connection between the two pipes. For ease of description, this embodiment uses one limiting connection component 2 as an example. Specifically, the limiting connection component 2 includes: a first limiting plate 21, a second limiting plate 22, a first connecting rod 23, and two limiting grooves. The first limiting plate 21 is disposed on the first connecting component 3 and is locked to the first connecting component 3 by a locking component. The second limiting plate 22 is disposed on the second connecting component 5 and is locked to the second connecting component 5 by a locking component. Limiting grooves are provided at both ends of the first connecting rod 23. The first connecting rod 23 passes through the first limiting plate 21 and the second limiting plate 22 in sequence. The first limiting plate 21 and the second limiting plate 22 slide within the two limiting grooves respectively to meet the distance requirements of the dynamic compensation expansion joint 1 under different deformation conditions. In this embodiment, in order to make the distance of the limiting grooves on the first connecting rod 23 adjustable to meet the usage requirements under different conditions, the limiting grooves at both ends of the first connecting rod 23 can be configured by providing a first limiting sleeve 231 and a second limiting sleeve 232 at both ends of the first connecting rod 23, with the first limiting sleeve 231 and the second limiting sleeve 232 spaced apart at both ends of the first connecting rod 23. Specifically, one end of the first limiting sleeve 231 is connected to one side of the first limiting plate 21, and one end of the second limiting sleeve 232 is connected to the other side of the first limiting plate 21; and one end of the first limiting sleeve 231 is connected to one side of the second limiting plate 22, and one end of the second limiting sleeve 232 is connected to the other side of the second limiting plate 22. In other words, a first limiting sleeve 231 and a second limiting sleeve 232 are provided on one end of the first connecting rod 23, allowing the first limiting plate 21 or the second limiting plate 22 to slide between the first limiting sleeve 231 and the second limiting sleeve 232, thereby making the limiting groove adjustable to meet the different requirements of the expansion joint 1's operating environment and enhancing the practicality of the expansion joint 1 structure.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
