A fan is fixedly connected to one side of the top of the composite shell near the output pipe, the middle of the inner side of the composite shell is connected to the output pipe, and the fan is connected to the top of the output pipe. Wind is generated by the fan to ventilate the inside of the composite shell, which, on the one hand, plays a role in heat dissipation and keeps the interior dry. On the other hand, internal dust is absorbed by wind force, so as to achieve the effect of cleaning the internal dust.

When the rotating block falls, the buffer top plate squeezes and compresses the spring coil, and the elastic material plays a shock-absorbing and buffering role, reduces the amplitude of the components, and maintains structural stability. A ring-shaped groove is opened in the middle of the top of the buffer top plate, and the inner side of the ring-shaped groove is rotatably connected to a cylindrical rotating block. When the fan stops operating, the rotating block falls onto the buffer top plate, and the wear of the components is reduced by the silicone block.

Paddle boards are fixedly connected between the opposite surfaces of the outer side of the connecting bracket, and the wind force generated by the fan drives the rotating mechanism to rotate, and the contact area with the air is increased through the paddle boards, thereby improving the rotation efficiency.

[0010] Preferably, the processing mechanism includes a receiving plate, the bottom of which is fixedly connected to the top of the cabinet, and the inner wall of the receiving plate is fixedly connected with an adjusting mechanism.

When the cylindrical block rotates inside the receiving shell, the square slide groove and the square slider are in friction contact, so as to limit the rotation speed of the component and avoid excessive rotation affecting the stability of the material inside the equipment. The outer side of the square slider is slidably connected to the inner side of the square slide groove, and when the square slider is supported by the elastic structure of the connecting rod, it has a certain elastic shaking, which can reduce direct collision of components while buffering the rotation speed and extend the service life of the equipment.

[0014] The present invention provides a display cabinet having the following beneficial effects: 1. The display cabinet, through the composite structure design, places the materials inside the composite shell for closed display, avoids bumping against the materials and reduces dust entry. The output pipe is connected to the middle of the inner side of the composite shell, and the fan is connected to the top of the output pipe. The fan generates wind to ventilate the inside of the composite shell. On the one hand, it plays a role in heat dissipation and keeps the interior dry. On the other hand, the wind absorbs the internal dust to achieve the effect of cleaning the internal dust. The wind generated by the fan drives the rotating block to slide, and the annular block rubs the inner wall of the pipe to reduce dust accumulation and avoid affecting the ventilation effect. A square incision is opened, and the chip removal effect is increased by grooving, reducing impurities and avoiding affecting the friction effect. By opening a groove on the block surface, the force area of ​​the component surface is increased, and the rotation friction effect is improved. The silicone block is made of silicone material and has a certain shock absorption effect, so as to achieve the effect of shock absorption and buffering, reduce component wear, and extend the service life of the equipment.

[0015] 2. The display cabinet is designed with a buffer mechanism. When the fan stops working, the rotating block falls onto the buffer top plate, and the wear of the components is reduced by the silicone block. At the same time, the silicone block is connected to the inside of the ring-shaped groove and rubs against the columnar bricks, so as to limit the movement of components, reduce the activity space of components, and reduce internal collision noise. When the rotating block falls, the buffer top plate squeezes and compresses the spring coil, and the elastic material plays a shock-absorbing and buffering role, reducing the amplitude of the components and maintaining structural stability.

[0016] 3. The display cabinet is designed with a protective mechanism. By placing the filter plate into the connecting shell, when the fan blows wind through the protective shell, it contacts the filter plate, thereby filtering impurities and moisture, reducing internal impurities, and protecting objects. At the same time, it is easy to replace and operate for a long time. By opening a filter plate groove and increasing the contact area through the grooving, the filtering effect is improved. By pushing the filter plate to squeeze the elastic rod, the component is pushed through the elastic structure of the elastic rod, thereby facilitating the removal of the component. The external block is made of plastic material to increase the friction effect and improve the stability of the component.

[0017] Fourth, the display cabinet is designed with a rotating mechanism. The wind force generated by the fan drives the rotating mechanism to rotate, and the paddle increases the contact area with the air to improve the rotation efficiency. Then, it drives the connecting bracket to rotate, so that the curved scraper rubs against the inner wall of the pipe, thereby cleaning the inner wall of the pipe, reducing dust accumulation during operation, and maintaining ventilation efficiency.

[0018] 5. The display cabinet is designed with a processing mechanism, and the top of the adjustment mechanism is connected to the bottom of the composite shell. The composite mechanism is rotated by the adjustment mechanism to facilitate the adjustment of the exhibition direction and improve the viewing effect. When the external force impacts the equipment, the rocker drives the counterweight to shake. The counterweight generates an opposite force when the structure vibrates through inertia, and works together with other parts of the processing mechanism to consume vibration energy, thereby reducing the vibration amplitude of the equipment under the impact, ensuring the stability and safety of the components, and improving the safety of the equipment, thereby maintaining the safety of the exhibition materials.
