The invention belongs to the field, and particularly relates to a fire-fighting signal butterfly valve which comprises a valve body, a valve rod and a butterfly plate, a cover is arranged outside the valve body, two fixing pieces used for clamping the valve rod are arranged at the position, located at the bottom of a transmission wheel, of the valve rod, and a clamping groove is formed in the face, opposite to the fixing pieces, of the bottom of the transmission wheel. The butterfly valve is installed and used for a long time, if a loose tooth is corroded and loosened under other conditions that water, external air and the like pass through the outside of the valve rod, the butterfly valve cannot be opened after a master end drive transmits a signal to a controller to start a driving motor during temporary fire-fighting application, and the valve rod cannot be opened. At the moment, the two fixing pieces can move at the same time to clamp the valve rod, the fixing pieces can be driven to rotate at the same time after the transmission wheel rotates, the clamped valve rod is driven, and therefore the standby effect is achieved, it is guaranteed that the valve rod can be continuously used when meeting the fire fighting problem, and the situation that the valve rod cannot be opened due to damage is avoided. And fire rescue or fire emergency is delayed.

A cable saddle anti-sliding structure with a movable adjusting function comprises a bunching cable saddle (1) and is characterized in that a first anti-sliding pressing plate (4) is arranged at one end of the bunching cable saddle (1), a second anti-sliding pressing plate (5) is arranged at the other end of the bunching cable saddle (1), counter bores (6) are formed in the anti-sliding pressing plates corresponding to steel strand penetrating holes of the bunching cable saddle (1) respectively, and the counter bores (6) are connected with the first anti-sliding pressing plate (4) and the second anti-sliding pressing plate (5). The counter bores (6) on the first anti-sliding pressing plate (4) and the second anti-sliding pressing plate (5) are internally provided with spherical cylinders (7) respectively, the outer side of the spherical cylinder (7) on the first anti-sliding pressing plate (4) is provided with a fixer (10), and the outer side of the spherical cylinder (7) on the second anti-sliding pressing plate (5) is provided with a movable regulator (13). And stress concentration can be effectively avoided, single cable replacement can be achieved, and the safety and reliability of the structure are improved.

This utility model relates to the field of medical testing technology and aims to solve the problems of low information signing efficiency, high labor and time costs, and easy introduction of errors in the existing technology of manually entering sample information into the system. The utility model provides a sample ring, which is a ring-shaped structure used to fit over a sample tube. The sample ring has a built-in NFC chip that stores sample information data. The NFC chip is used to cooperate with an NFC device, enabling the NFC device to read the data in the NFC chip and sign for the sample information. This utility model uses an NFC chip to store sample information, accurately recording the sample information. When the NFC chip is brought close to an NFC device, the NFC device can quickly receive the data in the NFC chip and obtain the sample information, eliminating the need for manual entry, improving information signing efficiency, and saving human resources and time costs.
