[0035] The working principle of the present utility model:

[0036] When the template is short and needs to be adjusted upward, by pulling the support plate 3 upward to the right, the support plate 3 moves on the surface of the slide bar 42 through the sliding grooves 41 opened on both sides. At the same time, the support plate 3 drives the box body 51 to move. When the box body 51 moves, the left end of the chuck 522 extending out of the box body 51 will be squeezed by the left inner wall of the adjustment groove 6, so that the chuck 522 is squeezed and slides into the box body 51 on the surface of the positioning rod 521, and at the same time, the push spring 523 is squeezed and compressed. In this way, it moves upward. After moving the chuck 522 to a suitable adjustment position, the push spring 523 will rebound and push the chuck 522 downward on the surface of the positioning rod 521, so that the chuck 522 is inserted into the corresponding adjustment groove 6 to fix the support plate 3, thus completing the adjustment. When the template is long and needs to be adjusted downward, by pulling the pull button 545 downward to the left, the slider 542 is driven to move leftward on the surface of the slide rod 541. While the slide rod 541 moves, it drives the two pull rods 543 in the two extrusion grooves 534 to move and squeeze the two extrusion grooves 534, so that the two rotating parts 532 are squeezed and rotate upward at the right end with the two fixed rods 531 as the center on the surface of the two fixed rods 531. At the same time, it drives the two pressure rods 533 in the two stroke grooves 524 to move and squeeze the two stroke grooves 524, so that the chuck 522 is squeezed and moves upward on the surface of the two positioning rods 521, thus releasing the positioning of the support plate 3. Then, the support plate 3 is pulled downward until the chuck 522 corresponds to a suitable adjustment. After that, the pull button 545 is released, so that the spring 544 rebounds to push the slider 542 back and forth, and at the same time, the pull rod 543 no longer squeezes the extrusion groove 534. The rotating part 532 rotates back to its original position. At the same time, the push spring 523 pushes the chuck 522 downward into the corresponding adjustment groove 6 to position the support plate 3, so as to adjust downward.

[0037] In summary, for the detection device of the fireproof performance of building materials, by the combined use of the chassis 1, the support frame 2, the support plate 3, the adjustment sliding assembly 4, the sliding groove 41, the slide bar 42, the adjustment positioning device 5, the box body 51, the clamping assembly 52, the positioning rod 521, the chuck 522, the push spring 523, the stroke groove 524, the linkage assembly 53, the fixed rod 531, the rotating part 532, the pressure rod 533, the extrusion groove 534, the control assembly 54, the slide rod 541, the slider 542, the pull rod 543, the spring 544, the pull button 545 and the adjustment groove 6, the problem that when the existing small chamber method fireproof coating tester tests templates with different lengths, it is necessary to adjust the position of the support plate on the support frame, but its support plate is usually adjusted and fixed in cooperation with the support frame by bolts. In this way, tools need to be repeatedly used to tighten the bolts during adjustment, which is rather troublesome and thus affects the adjustment work efficiency during the test is solved.
