Description

Technical Field

[0001] The utility model relates to the technical field of sterilization equipment, in particular to a locking structure of a sterilization tank. Background Art

[0002] When the sterilization tank is in use, it is necessary to ensure that the sterilization tank can operate normally and stably, so a locking structure of the sterilization tank is required.

[0003] For example, the locking structure of a steam sterilization tank with patent announcement number CN205832212U pushes the U-shaped hoop lock downward through the swing shaft in the middle of the locking handle. When the cross arm of the U-shaped hoop lock is lower than the protrusion, the U-shaped hoop lock is flipped inward to clamp the cross arm of the U-shaped hoop lock in the groove on the bottom surface of the protrusion. Then the locking handle is flipped inward, and the lid of the steam sterilization tank is locked on the tank body.

[0004] However, during actual use of the above-mentioned locking structure, manual support is required when the U-shaped hoop lock and the groove on the bottom surface of the protrusion are engaged with each other, and the operator's hand may be clamped during this process. In addition, during long-term use, the U-shaped hoop lock and the groove on the bottom surface of the protrusion will continue to rub against each other, reducing the service life of the U-shaped hoop lock. For this reason, the applicant proposes a locking structure for a sterilization tank. Utility Model Content

[0021] With the continuous development of science and technology, more and more industries are now using sterilization tanks. When the sterilization tank is in use, a locking mechanism needs to be installed on the sterilization tank to ensure the stability of the sterilization tank. Therefore, a locking structure for the sterilization tank is needed. In the actual use of most traditional locking structures, the locking mechanism of the device is relatively cumbersome, and the operator is required to clamp the locking mechanism in different ways, which reduces the convenience of the device. For this reason, the applicant proposes a locking structure for the sterilization tank.
