[0042] Referring to Figures 3 to 4 The limiting plate 14 is fixedly connected to the top of the experimental table 15, which is a core operation platform for conducting fire cause experiments, and is generally made of materials with high temperature resistance, corrosion resistance and certain strength, such as stainless steel or ceramic composite material. The experimental table 15 is fixedly connected to the top of the placing plate 16, which is used for placing experimental samples, instruments and equipment or experimental tools, and is made of the same high-temperature-resistant material as the experimental table 15. The experimental table 15 is fixedly connected to the outside of the front side of the socket 17, which is an interface for providing power connection for experimental instruments and equipment, and the type can be selected according to experimental requirements, such as ordinary AC socket or special DC socket 17. The socket 17 is generally made of engineering plastic or metal, and the engineering plastic socket has the advantages of good insulation performance and low cost, which can effectively prevent electric shock accidents;
[0043] The button 18 is externally fixedly connected to the experimental bench 15, and is generally made of plastic or metal as a component for controlling certain functions or operations of the experimental device. The plastic button has the advantages of low cost, comfortable feel, good insulation performance, etc. The sliding rod 12 is externally slidably connected to the inside of the base 1, and the limiting plate 14 is externally slidably connected to the inside of the base 1. The edge of the limiting plate 14 is treated to make it have a smooth contact surface with the inside of the base 1 and high adhesion, thereby reducing friction and jamming. During the experiment, when the experimental bench 15 is subjected to an external force or has a displacement trend due to internal structural changes, the limiting plate 14 can slide along the predetermined track in the base 1. The outer rotating plate 5 is rotatably connected to the inside of the top cover 3, and the outer anti-collision plate 8 is in contact with the inside of the top cover 3. One end of the spring 10 is fixedly connected to the outside of the anti-collision plate 8, and the other end of the spring 10 is fixedly connected to the outside of the damping block 7.
[0044] When the anti-collision plate 8 is subjected to an impact force, the spring 10 is compressed to store elastic potential energy, and at the same time, the damping block 7 is deformed due to the force to consume part of the impact energy. Through the synergistic effect of the spring 10 and the damping block 7, the impact on the experimental device is effectively reduced, and the safety of the device is protected. The outer anti-collision plate 8 is in contact with the outside of the experimental bench 15, and when the anti-collision plate 8 is subjected to an impact force, the damping block 7 will slide on the fixed rod 9, consume a large amount of impact energy through its deformation and friction with the fixed rod 9, and play a role in buffering and shock absorption, effectively protecting the experimental device from serious damage. The outer damping block 7 is slidably connected to the outside of the fixed rod 9, and the outer anti-collision plate 8 is in contact with the outside of the connecting frame 4.
[0045] Working principle: First, the base 1 serves as the supporting structure of the entire device, providing a solid foundation to withstand various forces and vibrations during the experiment. The experimental bench 15 is located inside the base 1 and is connected to the base 1 through the limiting assembly. The limiting plate 14 can slide within the base 1 to accommodate the displacement of the experimental bench 15 due to external forces or internal structural changes. When the experimental bench 15 is subjected to an impact, the limiting plate 14 will slide along the predetermined track to ensure that the experimental bench 15 remains in a safe position.
[0046] During the experiment, the protection mechanism plays a key role. The anti-collision plate 8 directly contacts the experimental bench 15 and can absorb part of the energy when subjected to external impact. At this time, the compression of the spring 10 stores elastic potential energy, and the deformation of the damping block 7 consumes impact energy, thereby effectively reducing the impact on the entire device. The deformation of the damping block 7 and the friction between the damping block 7 and the fixed rod 9 work together to further reduce the impact force and protect the integrity of the experimental device.
[0047] In addition, the protection mechanism on the top cover 3 is combined by the connecting frame 4 and the rotating plate one 5, by pushing the experiment table 15 into the inside of the base 1, at this moment, by rotating the top cover 3, the anti-collision plate 8 outside the top cover 3 can be in contact with the experiment table 15, then the anti-collision plate 8 can extrude the spring one 10, then the damping block 7 drives the rotating plate one 5 to rotate, so that the anti-collision plate 8 can be in contact with the experiment table 15, and the safety of the device is enhanced, and accidental collision is prevented. The design of the experiment table 15 enables it to withstand high temperature and corrosion, which meets the requirements of fire cause experiment. The socket 17 and the control button 18 in the device provide power and operation convenience, so that the experiment process is more efficient and safe.
[0048] By rotating the connecting rod 20 outside the top cover 3, the connecting rod 20 can drive the clamping rod 22 outside the rotating plate two 21 to be clamped with the outside of the base 1, then the installation of the top cover 3 can be realized, and the experiment table 15 is prevented from being popped out. Overall, the device ensures the smooth progress of the fire cause experiment through the coordinated work of various components, and maximally reduces the potential safety risk.
