The dynamic ring and the static ring are pressed tightly together by elastic elements such as springs or air bags to prevent liquid or gas leakage from the inside of the machine.

[0003] According to the "A Mechanical Seal Detection Device" with Chinese Patent Publication No. CN212963893U, it mainly describes that the connecting head inside the connecting mechanism is changed into a boss-shaped structure, and the cross-sectional diameter at the upper end of the connecting head is larger than the connecting diameter at the lower end, so that when plugging in, the connecting heads with different cross-sectional diameters can be connected to the connecting holes more tightly, avoiding the phenomenon of inaccurate detection caused by loose connection; a lifting mechanism is arranged at the upper end axis of the cross bar, and a pressure rod is arranged at the inner bottom end of the lifting mechanism, so that after the connecting head is tightly plugged in, the lifting mechanism drives the pressure rod at the bottom end to contact with the support plate, so that under the action of the pressure rod, the connecting mechanism can be fixed more tightly, effectively avoiding the phenomenon of air leakage during detection. In this process, the mechanical seal is in a static state, and the state of the mechanical seal cannot be well simulated, resulting in poor detection effect.

[0004] Therefore, a mechanical seal detection device is proposed to solve the problem that during this process, the mechanical seal is in a static state and the state of the mechanical seal cannot be well simulated, resulting in poor detection effect. Utility Model Content

A protrusion is fixedly connected to the connecting rod 11 on the side away from the arc-shaped bar 12. A single adjustment of the connecting rod 11 can make the two arc-shaped bars 12 in a dislocated structure, so that the protrusion of the mechanical sealing device can be stuck between the two arc-shaped bars 12.
