[0024] Example 1, as Figure 1 - Figure 4 As shown, the utility model provides a concrete freeze-thaw resistance test device, including a test box 1, the interior of the test box 1 is provided with a convenient disassembly and assembly component 2, the convenient disassembly and assembly component 2 includes a test box 201, the bottom surface of the test box 201 is provided with a sealing groove 202, the inner walls of both sides of the test box 201 are provided with slots 203, the bottom of the test box 201 is connected to a bottom plate 204, the bottom outer surface of the bottom plate 204 is connected to a sealing ring 205, the inside of both sides of the bottom plate 204 are connected to two sets of springs 206, the two sets of springs 206 Push rods 207 are inserted into the interior of the two groups of push rods 207, one side of the push plate 208 is connected to the plug block 209, and the other side of the two groups of push rods 207 is connected to the handle 210. The position and size of the sealing ring 205 match the position and size of the sealing groove 202, and the sealing ring 205 and the sealing groove 202 form a snap-fit connection. An oblique opening is provided on one side of the plug block 209, and the plug block 209 and the slot 203 form a plug-fit connection. An elastic structure is formed between the push plate 208 and the spring 206.
[0025] The effect achieved by the entire embodiment 1 is that when the concrete test is completed and the concrete needs to be taken out, the test box 201 can be directly pulled out of the test box 1, and then the two sets of handles 210 are pushed inward at the same time, so that the handles 210 can drive the push plate 208 to move inward through the push rod 207, and squeeze the spring 206, so that the push plate 208 can drive the insert block 209 to be pulled out from the slot 203, and then the bottom plate 204 is pushed by a rod-shaped tool, and the bottom plate 204 slides from the bottom to the top along the inner wall of the test box 201, so that the concrete sample is smoothly and completely pushed out of the test box 201, and then the subsequent During the test, when the bottom plate 204 needs to be pushed toward the bottom of the test box 201, the oblique position of the insert block 209 will automatically retract into the bottom plate 204 after being squeezed. When the bottom plate 204 is completely pushed to the bottom of the test box 201, the spring 206 will push the push plate 208 through its own elastic force to drive the insert block 209 to be inserted into the slot 203 for fixation, thereby completing the installation and fixation of the bottom plate 204.
