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

[0014] 1. Precise clamping and stable testing: This device uses a main-auxiliary dual clamping structure. Clamping plate one and rubber pad one achieve initial clamping. Clamping plate two adapts to the edge shape of the test block and presses the test block tightly under the action of spring force. Rubber pad two increases friction and effectively prevents the test block from shifting laterally, ensuring the stability of the concrete test block during the testing process and providing a reliable guarantee for accurate testing.

[0015] 2. Multi-dimensional Precision Positioning Testing: The testing mechanism uses a combination of components such as crossbeam one, crossbeam two, threaded rod, motor, and electric telescopic rod to achieve precise positioning in three directions: front and back, left and right, and up and down. This allows the concrete rebound hammer to accurately align with different positions of the test block, supports continuous testing at multiple points, improves the comprehensiveness and accuracy of the testing, and enables a more accurate assessment of the overall performance of the concrete.

[0016] 3. Simulated Temperature Environment Testing: This device can simulate high and low temperature environments to test the strength of concrete specimens under different temperature conditions. High-temperature air and cold air are supplied to the chamber by a hot air blower and a cold air blower, respectively. Combined with real-time temperature monitoring by a thermometer, the temperature of the testing environment can be precisely controlled, simulating extreme temperature conditions that may be encountered in actual engineering projects. This provides strong support for evaluating the performance of concrete under different temperature environments and helps to more comprehensively understand the performance variation patterns of concrete.

[0017] 4. Efficient environmental switching and rapid cooling: When simulating a low-temperature environment, the electric telescopic rod retracts, causing the baffle to disengage from the lower port of the exhaust chamber. The electric fan starts to accelerate the discharge of hot air from the casing, effectively shortening the cooling preparation time and improving the detection efficiency. This allows the device to quickly switch to the low-temperature detection state to meet different detection needs.

[0018] 5. Convenient operation and visualization: The front face of the shell is equipped with a door for easy placement and removal of concrete test blocks; the door is equipped with an observation window for operators to observe the testing process in real time; the thermometer provides real-time feedback of the temperature data inside the shell, enabling operators to accurately grasp the testing environment and adjust the testing parameters in a timely manner to ensure the smooth progress of the testing process.

[0019] In summary, through the aforementioned series of innovative designs, this utility model possesses numerous significant advantages, including precise clamping and stable detection, multi-dimensional precise positioning detection, detection in simulated different temperature environments, efficient environment switching and rapid cooling, convenient operation and visualization. These advantages make the device highly practical in the field of concrete performance testing, with a very broad application prospect, and it can provide solid and powerful support for engineering quality assurance.

[0033] When using this utility model, open the switch door on the front end of the housing 1, place the concrete test block horizontally on the inner bottom surface of the housing 1 between the two clamping mechanisms, ensuring that the center of the test block is aligned with the testing mechanism, rotate the threaded rod 3 of the two clamping mechanisms respectively, and push the crossbar 4 along the slide groove 7 towards the test block through the threaded transmission. The crossbar 4 drives the clamping plate 5 and the rubber pad 6 to fit against the side of the test block. The rubber pad 6 can increase the friction and achieve initial clamping. When the crossbar 4 moves, the connecting rod 8 simultaneously pushes the slide bar 9 to slide along the outer sleeve rod 10, compressing the spring 11.

[0035] When a simulated high-temperature environment is required, the hot air blower 16 is started to deliver high-temperature air into the interior through the side wall of the shell 1. The thermometer monitors the temperature inside the cavity in real time. When the temperature reaches the preset value (such as 40℃ / 60℃ / 80℃), the concrete rebound hammer 29, driven by the electric telescopic rod 28, performs a strength retest on the heated test block.

[0036] When a simulated low-temperature environment is required, the electric telescopic rod 20 retracts, causing the baffle 19 to disengage from the lower port of the exhaust chamber 17. The electric fan 18 starts, accelerating the exhaust of hot air from the housing 1 through the filter structure, shortening the cooling preparation time. The baffle 19 resets and seals the exhaust chamber 17. The air cooler 15 delivers cold air into the housing 1. The thermometer feeds back low-temperature data (e.g., -10℃ / 0℃ / 10℃). The concrete rebound hammer 29 performs the low-temperature environment test.
