[0038] The first hole segment 11 , the second hole segment 21 , the third hole segment 31 , and the slot segment are connected.

[0039] In a specific embodiment, as shown in the figure, before testing, one end of the pipe to be tested is inserted into the first hole section 11 of the first clamp 1, and then the second hole section 21 of the middle clamp 2 is sleeved on the middle part of the pipe, and the third hole section 31 of the second clamp 3 is sleeved on the other end of the pipe. During testing, the test liquid is injected from the first hole section 11 into the burst test fixture of the pipe, and the test liquid enters the pipe to be tested to test whether the pipe to be tested explodes under the hydraulic pressure, so as to conveniently, quickly and accurately judge whether the bursting ability of the pipe to be tested is qualified. When the pipe to be tested explodes, the fragments of the pipe to be tested enter the groove section. The burst test fixture of the pipe adopts a split structure design, which is conducive to the installation of the pipe to be tested, has a simple structure, and is easy to repair or replace parts.

[0040] The structure, shape and position of the slot section in the present application are not limited. In a specific embodiment, the slot section includes a first slot section 41, which is arranged on the side of the first clamping block 1 close to the middle clamping block 2, and the cross-sectional area of ​​the first slot section 41 is larger than the cross-sectional area of ​​the first hole section 11. As shown in the figure, the slot section is arranged on the right side of the first clamping block 1, and the slot section is not only conducive to inserting the pipe into the first hole section 11 from the right side, but also conducive to collecting pipe fragments when the pipe explodes.

[0048] The first mounting hole 12, the second mounting hole 22, and the third mounting hole 32 are connected;

[0049] The bursting test fixture for the pipe also includes mounting bolts, which pass through the first mounting hole 12, the second mounting hole 22, and are threadedly connected to the third mounting hole 32, so as to fix the first clamping block 1, the second clamping block 3, and the third clamping block as a whole.

[0050] In the present application, the positions and numbers of the first mounting hole 12, the second mounting hole 22, and the third mounting hole 32 are not limited. In a specific embodiment, the first clamping block 1 includes four first mounting holes 12, and any of the first mounting holes 12 is disposed at a corner of the first clamping block 1.

[0051] The middle clamp block 2 is provided with four second mounting holes 22.

[0052] The second clamping block 3 is provided with four third mounting holes 32.

[0053] The positions of the first mounting hole 12, the second mounting hole 22 and the third mounting hole 32 correspond one to one. This structure can ensure that the first clamping block 1, the middle clamping block 2 and the second clamping block 3 are more firmly connected, which is convenient for testing the performance of the pipe to be tested.

[0054] Finally, it should be noted that the above specific implementation methods 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 examples, 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.
