[0031] Example 1

[0032] Combined with Figure 1-4 , this embodiment provides a pipeline connection structure, including:

[0033] A first clamp 1, wherein the first clamp 1 is provided with a first through groove 11 and a first groove 12 which are interconnected;

[0034] A second clamp 2 detachably connected to the first clamp 1, wherein the second clamp 2 is provided with a second through groove 21 and a second groove 22 which are in communication with each other, wherein the second through groove 21 is in communication with the first through groove 11, and the second groove 22 is in communication with the first groove 12;

[0035] A first sealing member 31 is located in the first groove 12, and an axial dimension of the first groove 12 is smaller than an axial dimension of the first sealing member 31;

[0036] The second sealing member 32 is located in the second groove 22 , and the axial dimension of the second groove 22 is smaller than the axial dimension of the second sealing member 32 .

[0037] Specifically, the first clamp 1 and the second clamp 2 cooperate with each other to connect adjacent pipe bodies; the first through groove 11 and the second through groove 21 are connected to each other to form a pipe accommodating groove, which is used to accommodate adjacent pipe bodies; the first groove 12 is used to prevent the first seal 31 from moving axially, and the second groove 22 is used to prevent the second seal 32 from moving axially. The first seal 31 and the second seal 32 are used to jointly increase the sealing of the connection between adjacent pipe bodies. Since the axial size of the first groove 12 is smaller than the axial size of the first seal 31, it is convenient for the first groove 12 and the first seal 31 to achieve a tight fit and prevent the first groove 12 and the first seal 31 from separating from each other. Since the axial size of the second groove 22 is smaller than the axial size of the second seal 32, it is convenient for the second groove 22 and the second seal 32 to achieve a tight fit and prevent the second groove 22 and the second seal 32 from separating from each other. Among them, the materials of the first seal 31 and the second seal 32 can be fluororubber, silicone rubber, etc.

[0038] Further, such as Figure 1 , also includes:

[0039] A first gap 41 formed between one end of the first sealing member 31 and one end of the second sealing member 32;

[0040] A second gap 42 is formed between the other end of the first sealing member 31 and the other end of the second sealing member 32 .

[0041] Specifically, when assembly is completed, the adjacent pipe bodies will radially squeeze the first seal 31 and the second seal 32. The first gap 41 and the second gap 42 are convenient for accommodating the squeezed parts of the first seal 31 and the second seal 32 to prevent excessive interference between the first seal 31 and the second seal 32 after squeezing.

[0042] Further, such as Figure 1-3 The radial dimension of the first sealing member 31 is larger than the radial dimension of the first groove 12 , and the radial dimension of the second sealing member 32 is larger than the radial dimension of the second groove 22 .

[0043] Specifically, it is convenient to make the first sealing member 31 and the second sealing member 32 closely contact the connection between the adjacent pipe bodies, thereby further improving the sealing performance of the connection between the adjacent pipe bodies.

[0044] Further, such as Figure 1 , also includes:

[0045] Two first connecting ears 13 respectively connected to the two ends of the first clamp 1;

[0046] Two second connecting ears 23 respectively connected to the two ends of the second clamp 2;

[0047] The two first connecting ears 13 and the two second connecting ears 23 are detachably connected to each other via the fasteners 6 .

[0048] Specifically, the two first connecting ears 13, the two second connecting ears 23 and the fastener 6 are used to jointly realize a detachable connection between the first clamp 1 and the second clamp 2. The fastener 6 can be a hexagonal head bolt assembly, a round head bolt assembly, etc.

[0049] Further, such as Figure 2-3 The two first connecting ears 13 are respectively provided with two groups of first through holes 131 , and the two second connecting ears 23 are respectively provided with two groups of second through holes 231 . The two groups of first through holes 131 and the two groups of second through holes 231 are both used to accommodate the fasteners 6 accordingly.

[0050] Further, such as Figure 1-3 The two first connecting ears 13 are integrally connected to the first clamp 1 , and the two second connecting ears 23 are integrally connected to the second clamp 2 .

[0051] Specifically, the one-piece connection facilitates increasing integrity, thereby facilitating ensuring strength.

[0052] Further, such as Figure 1 and 4 , and also includes a kit 5 wrapped around the first clamp 1, the second clamp 2, the two first connecting ears 13 and the two second connecting ears 23. The kit 5 and the two first connecting ears 13 and the two second connecting ears 23 are all detachably connected via fasteners 6.

[0053] Specifically, the kit 5 is used to increase the connection firmness of the first clamp 1, the second clamp 2, the two first connecting ears 13 and the two second connecting ears 23 to prevent them from falling apart.

[0054] Further, such as Figure 1 and 4 , and also includes two groups of accommodating holes 51 respectively arranged at both ends of the kit 5, and the two groups of accommodating holes 51 are used to accommodate the fasteners 6.

[0055] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
