[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is China's customary abbreviation for gas compression and gas delivery machinery. The fans usually mentioned include ventilators, blowers, and wind turbines. Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selection of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc.

[0003] The fan needs to use a fan soft connector during use to better transport gas. The fan soft connection is an important way to connect the fan with pipelines, machines and other equipment. It uses elastic materials such as hoses to connect the fan and other equipment. Its function is to reduce the vibration and noise between the fan and other equipment, thereby protecting the safety and normal operation of the equipment.

[0004] However, the use of soft connections at the fan inlet may affect safety performance. Although the soft connection has a certain degree of flexibility and can adapt to a certain degree of deformation, its tensile strength is relatively poor. For the safe operation of the fan, the soft connection is not as durable as the hard connection, has poor safety performance, is easy to break, and causes safety hazards. Therefore, a fan soft connector with anti-leakage function is proposed to solve the above problems. Utility Model Content

[0009] Furthermore, the tightening assembly includes a shell, an elastic rope installed inside the shielding sleeve and passing through the shell, a piston rod movably installed inside the shell, two pressure plates symmetrically arranged inside the shell, and a return spring and a telescopic rod fixedly installed between the two pressure plates.

[0010] Furthermore, the shell and the piston rod are both provided with through holes, and both ends of the elastic rope penetrate the shielding sleeve and penetrate the shell and the piston rod through the through holes.

[0012] Furthermore, two mounting blocks are symmetrically installed inside the shell, and two piston rods penetrate the inside of the two mounting blocks. A guide rod penetrating the inside of the two pressure plates is fixedly installed between the two mounting blocks.

[0013] Furthermore, the return spring surrounds the outside of the telescopic rod, and both ends of the shielding sleeve pass through.

[0014] Furthermore, the number of the reinforcement structures is five, and the five reinforcement structures are equidistantly distributed between the two connecting flanges.

[0015] Compared with the prior art, the utility model provides a fan soft connector with anti-leakage function, which has the following beneficial effects:

[0016] 1.
