The top end of the lifting rod extends out of the top end wall of the fixed housing and connects to a lifting device. The bottom end of the lifting rod is fixedly connected to a mounting block, which is cylindrical. A pressure plate is rotatably connected to the bottom end of the mounting block. A movable plate is installed above the pressure plate, with a central hole at its center, through which it fits onto the outside of the mounting block. Several longitudinally arranged nail teeth are provided at the bottom end of the movable plate, with the top ends of the nail teeth connecting to the bottom end of the movable plate and the bottom ends of the nail teeth inserting into several longitudinal through holes provided on the pressure plate. A power mechanism is provided at the upper end of the movable plate, driving the movable plate to rotate. A lifting mechanism is provided between the movable plate and the pressure plate, adjusting the height of the movable plate.

[0004] The existing compression rebound testing equipment uses adhesive bonding to bond the specimens, which easily damages the specimens and can only test one specimen at a time, resulting in low efficiency. Therefore, it does not meet the current requirements. To address this, a compression rebound device for rubber and plastic insulation boards is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a compression rebound device for rubber and plastic insulation boards, so as to solve the problems mentioned in the background art that the existing compression rebound test equipment uses an adhesive method to easily damage the test specimens, and can only test one test specimen at a time, resulting in low efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber and plastic insulation board compression and rebound device, comprising: an assembly frame, an upper pressure plate for compressing and limiting test specimens is provided below the assembly frame, an adjusting component for adjusting the height of the upper pressure plate is installed above the upper pressure plate, a lower pressure plate for supporting the test specimens is provided below the upper pressure plate, a separating component for separating and placing test specimens is installed above the lower pressure plate, and a steel rod support is installed between the upper pressure plate and the lower pressure plate.

[0007] Preferably, the partition component includes a frame, and a plurality of vertical partition strips for dividing the internal space are installed inside the frame. A plurality of assembly openings are provided on the outer wall of the vertical partition strips, and horizontal partition strips are installed inside the assembly openings.

[0008] Preferably, the frame has several slots on its edge for engaging the ends of the vertical and horizontal dividing strips.

[0009] Preferably, the separator is made of alkali-resistant plastic and has the following dimensions: 5mm high, 155mm long, 155mm wide, 2mm thick, and 50x50mm spaced apart.

[0010] Preferably, a plurality of balance bolts for adjusting the level are installed below the lower pressure plate, and a level bubble for observing the levelness is installed above the lower pressure plate.

[0011] Preferably, the adjusting component includes an adjusting screw installed in the screw hole of the mounting bracket, an adjusting handwheel is installed at the upper end of the adjusting screw, and an adjusting nut for combination with the lower bottom of the adjusting screw is installed above the upper pressure plate.

[0012] Preferably, the steel rod support is 100mm long, and the front end face of the steel rod support is provided with a scale with an accuracy of 1mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the pixel insulation board specimen is restricted at the partition component. By adjusting the handwheel, the adjusting screw is rotated, which causes the upper pressure plate to move downward and contact the specimen below, applying downward pressure to the specimen and conducting a compression rebound test. By adjusting the handwheel, the adjusting screw is reversed, causing the upper pressure plate to move upward. After the specimen recovers, the thickness is measured again, and the rebound rate is calculated. The above structure can freely position different compression thicknesses to meet the needs of various thickness samples, especially for testing non-standard thickness samples.

[0015] (2) In this utility model, the space of the frame is divided by several vertical and horizontal dividing strips at the dividing component. The ends of each vertical and horizontal dividing strip are restricted and fixed by the buckles located on the frame edge. After the specimen is placed in each cavity, it will also be blocked by each dividing strip. This not only makes it convenient for users to test multiple specimens at one time in the compression rebound test, but also ensures the consistency of the results by having multiple samples in a unified compression state, avoiding the inconsistency of compression state caused by independent operation of a single sample. It also makes it more convenient to conduct control tests. In addition, it also makes it convenient for users to distinguish different specimens. According to the size of the specimen being tested, users can also easily adjust the position of the dividing strips to change the size of the dividing cavity. The overall operation is simple and easy for users to use.

[0016] (3) In this utility model, when the user conducts a pressure rebound test, the scale can be used to conveniently observe the scale to control the compression thickness, and the reading can be taken quickly, thus improving the test efficiency. Attached Figure Description

A leveling bolt 401 is used for adjusting the level, and a level bubble 402 for observing the levelness is installed above the lower pressure plate 4. A 50*50mm pixel insulation board specimen is placed into each compartment of the partition assembly 5. The adjusting handwheel 202 drives the adjusting screw 201 to rotate, causing the upper pressure plate 6 to move downwards and contact the specimen below, applying downward pressure. During the test, 50% compression is maintained. After 72 hours, the adjusting handwheel 202 is reversed to reverse the adjusting screw 201, causing the upper pressure plate 6 to move upwards. After the specimen recovers, the thickness is measured again, and the rebound rate is calculated. The closer the recovery height is to the original thickness, the better the rebound rate, the better the product's compressive strength, and the better the insulation performance after actual use. The above structure can freely position different compression thicknesses to meet the needs of various thickness samples, especially for testing non-standard thickness samples.

Several latches 502 are provided on the frame 501 for engaging the ends of the vertical separator bars 503 and the horizontal separator bars 504. The separator assembly 5 is made of alkali-resistant plastic and has dimensions of 5mm high, 155mm long, 155mm wide, and 2mm thick, spaced 50x50mm apart. The space of the frame 501 is divided by several vertical dividing strips 503 and horizontal dividing strips 504. The ends of each vertical dividing strip 503 and horizontal dividing strip 504 are restricted and fixed by the snap-fit ​​502 located on the frame 501.

In addition, it also makes it easy for users to distinguish different specimens. According to the size of the specimen being tested, users can also easily adjust the position of the dividing strips to change the size of the dividing cavity. The overall operation is simple and easy for users to use.
