Problems solved by technology

With the development of science and technology, people consider the retrospective requirements of medical biological sample storage devices, and apply smart lock technology to medical biological sample incubators as a locking structure for the cover and cover of the incubator. However, traditional smart locks cannot be separated from the power supply. Drive, among them, traceability, identification, driving lock switch and other actions need to be realized by power-driven machinery or communication units. Active smart locks are easily limited by accidents such as power outages, short circuits, and faults, and there is greater instability. Once this instability occurs in the biological incubator, for example, if the circuit of the predestined intelligent lock in the incubator loaded with test samples fails, it needs violent destruction or maintenance to unlock it, and violent destruction will lead to traceability and identification functions Ineffective, and maintenance will take a long time, which will easily affect the quality of the test samples and seriously affect the insulation effect of the sample incubator. Therefore, the intelligent locking structure of the incubator in the prior art lacks practicability and needs to be improved urgently

[0003] At the same time, the traditional sample incubator locking structure generally includes a lock tongue and a hasp. The lock tongue is driven by the driving source and hooked into the buckle of the hasp when the limit cover is required. In this structure, the lock tongue It is directly connected with the buckle. When the buckle is dragged by the cover body, it will exert this force on the lock tongue. Over time, the lock tongue is prone to deformation. The traditional lock tongue is driven by the driving source and mostly moves along a straight line. Therefore, , the deformed lock tongue has a negative impact on the overall movement path of the lock tongue, which may easily cause the lock tongue to fail to disengage from the buckle, resulting in invalid unlocking, which seriously affects the use of the sample incubator, and needs to be improved urgently

[0004] Moreover, most of the driving sources adapted to the above-mentioned dead bolt and hasp are linear telescopic driving sources, and mechanical linear telescopic driving sources generally tend to overdrive, for example, when the driving dead bolt is inserted into the hasp When using the buckle, the stroke length of the output end of the general driving source is much longer than the moving path length of the lock tongue, so as to ensure that the drive source can drive the lock tongue to the preset buckle smoothly, which makes the lock tongue easy to impact the buckle. On the inner wall of the cavity, over time, it is easy to damage the locking structure and affect the use of smart locks, which needs to be improved urgently
