[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1As shown, the structure of the combustible material for testing in this example includes a placement frame, which includes a base plate 1, a backing plate 2, and a pressure frame 4. The backing plate 2 is fixed longitudinally on the right side of the base plate 1, and the two are L-shaped. The pressure frame 4 is installed on the backing plate 2, and the right side of the backing plate 2 is installed with a lifting mechanism 3. In this example, the lifting mechanism adopts a common manual screw lift on the market, of course, it can also be replaced by an electric screw lift or a cylinder lift. The movable end of the lifting mechanism 3 is connected to the pressure frame 4, and the lifting mechanism moves the pressure frame up and down in the longitudinal direction.

[0020] In this example, the pressure frame 4 includes a horizontal portion 42 , a longitudinal portion 43 and a connecting portion 41 . The right end of the horizontal portion 42 is fixed to the upper end of the connecting portion 41 , and the left bottom surface of the horizontal portion 42 is connected to the longitudinal portion 43 .

[0021] like Figure 1 As shown, the connecting portion 41 is U-shaped, the top end of the back plate 2 extends into the U-shaped cavity of the connecting portion 41, and the right end of the connecting portion 41 is connected to the movable end of the lifting mechanism 3 on the right side of the back plate 2.

[0022] The right side of the horizontal part of the pressure frame 4 is grid-shaped, and a connecting hole is formed on the left side of the horizontal part 42. The longitudinal part such as the main body 430 is grid-shaped, and a fixing plate 431 is installed on the top surface of the longitudinal part main body 430. The head end of the fixing plate 431 is pivotally connected to the horizontal part 42 at the connecting hole.

[0023] A T-shaped slot 44 is formed on the left top surface of the connecting hole, and the slot 44 extends along the width direction of the horizontal part 42. The lower part of the push block 6 is in the slot 44 and the two are slidably matched. A through hole is formed at the bottom wall of the slot 44, and the bottom end of the push block 6 extends from the through hole and protrudes outside the bottom surface of the horizontal part. The head end of the connecting rod 5 below the horizontal part 42 is pivotally connected to the bottom end of the push block 6, and the tail end of the connecting rod 5 is pivotally connected to the fixed plate 431 in the longitudinal part 43. A waist hole 432 is formed in the middle part of the fixed plate 431 along the length direction, and the shaft at the tail end of the connecting rod 5 extends into the waist hole 432 to form a pivot connection.

[0024] When in use, the pressing frame is moved downward by the lifting mechanism, and the pushing block can be pushed to adjust the angle between the longitudinal portion and the horizontal portion.

[0025] In order to improve the stability of the movement of the pressing frame, a guiding mechanism 8 can be added, such as installing a guiding mechanism 8 between the transverse part of the connecting part 41 and the top of the lower support plate 2. The guiding mechanism is a common guide column and guide cylinder combination type. In addition, a cavity 21 can be preformed in the support plate 2, which helps to insulate.
