[0014] Example 1

[0015] like Figures 1 to 4 The multifunctional pressure testing machine shown includes an upper top plate 1, an upper bearing plate 2, a lower bearing plate 3, and a lower bottom plate 4 arranged in sequence from top to bottom. The upper top plate 1 and the lower bearing plate 3 are horizontal plates of the same size, and the upper bearing plate 2 and the lower bottom plate 4 are vertical plates of the same size. The upper top plate 1 and the lower bearing plate 3 and the upper bearing plate 2 and the lower bottom plate 4 are distributed in a cross-like manner. A plurality of columns 5 for connecting and fixing are provided between the upper top plate 1 and the lower bearing plate 3; the lower bottom plate 4 is also fixedly connected to the upper bearing plate 2 by a plurality of columns 5, and a plurality of slidingly connected guide rods 6 are provided between the upper bearing plate 2 and the lower bearing plate 3. This structural design makes the equipment more stable in force during operation, thereby improving the accuracy and stability of the test.

[0016] A first clamping block 9 is provided on the lower side of the upper bearing plate 2 and the upper side of the lower bearing plate 3. The two first clamping blocks 9 are opposite to each other up and down, and are used to clamp the test piece for pressure testing; a second clamping block 10 is provided on the lower side of the lower bearing plate 3 and the upper side of the lower base plate 4. The two second clamping blocks 10 are opposite to each other up and down, and are used to clamp the test piece for tension testing.
