Description

Technical Field

[0001] The utility model relates to the field of tensile testing machines, in particular to a high and low temperature wet heat box specially used for an automatic lifting tensile testing machine. Background Art

[0002] A tensile testing machine is also called a tensile testing machine or a universal material testing machine. The tensile test of a tensile testing machine: The tensile test strain test is generally to clamp the two ends of the material sample on two fixtures spaced a certain distance apart. The two fixtures separate and stretch the sample at a certain speed, and measure the stress change on the sample until the sample is damaged. Different materials need to be tested for their tensile force under high and low temperature environments, so a high and low temperature humidity chamber dedicated to the tensile testing machine is required. A high and low temperature humidity chamber dedicated to the tensile testing machine is a tensile testing machine that includes an environmental simulation function, that is, it can test the tensile and bending properties of the material under different temperatures or temperature changes.

[0003] After searching, a high and low temperature tensile testing machine with a publication number of CN218546403U is found, which specifically discloses a high and low temperature tensile testing machine, including a constant temperature box and a tensile component, the constant temperature box has a constant temperature chamber and a sample placement port, the constant temperature chamber is connected to the sample placement port, and there are protective doors and sealing doors inside and outside the sample placement port, the protective door has a vent, the vent is provided with a pressure relief component, and the vent is blocked after the sealing door is closed, the tensile component includes two fixing clamps and a tensile driving unit, the two fixing clamps are both arranged in the constant temperature chamber, the tensile driving unit is used to drive the two fixing clamps to move away from or close to each other, after the test, take out the test product, open the sealing door first, the sealing door no longer blocks the vent, the gas in the constant temperature chamber is discharged from the pressure relief component to reduce the pressure, and will not be directly discharged from the side where the sealing door is opened, thereby avoiding burns to the skin.

[0004] During the use of the existing high and low temperature humidity chamber dedicated to the tensile testing machine, different materials require different tensile testing machine fixtures when conducting tensile tests. If the high and low temperature chamber and the tensile testing machine are integrated into a structure, the replacement of the tensile testing machine fixture is not only cumbersome, but also delays the test time. In the above-mentioned comparative case, the tensile testing machine and the high and low temperature humidity chamber were not separated for use. This is not only inconvenient for maintenance when a fault occurs, but also the high and low temperature humidity chamber is easily deviated from its position on the load-bearing platform due to the influence of tension during use, thereby affecting the material test results.

[0005] Therefore, it is necessary to invent a high and low temperature humidity box for an automatic lifting tensile machine to solve the above problems. Utility Model Content

Through a fixed plate, a threaded rod, a clamping plate, a bearing platform, a fixed slider, a high-low temperature and humidity heat box body and a clamping plug block, the tensile testing machine and the high-low temperature and humidity heat box body can be disassembled for use, and it is also convenient to replace the clamp according to different material clamping requirements. At the same time, during the tensile test of the material, the stability of the high-low temperature and humidity heat box body on the machine platform is enhanced. In this way, the high-low temperature and humidity heat box body is prevented from easily deviating from its position on the bearing platform due to the influence of the tensile force during use, thereby affecting the material test results. The effect is to solve the problem in the prior art that during the use of the high and low temperature humidity chamber dedicated to the tensile testing machine, different materials require different tensile testing machine fixtures when conducting tensile tests. If the high and low temperature chamber and the tensile testing machine are integrated into a structure, the replacement of the tensile testing machine fixture is not only cumbersome, but also delays the test time. In the above-mentioned comparative case, the tensile testing machine and the high and low temperature humidity chamber are not separated for use, which is not only inconvenient to repair when a fault occurs, but also the high and low temperature humidity chamber is easily deviated from its position on the load-bearing platform due to the influence of tension during use, thereby affecting the material test results.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a tension machine frame 5 is fixedly installed on the top of the machine platform 1, and a sliding groove 6 is opened inside the tension machine frame 5. A sliding block 7 is movably connected inside the sliding groove 6.
