This utility model discloses a pressure test device for hydrogeological engineering surveys, including a main body and a support mechanism located on one side of the main body. This support mechanism reduces the sagging caused by the device connecting to the hose through bottom support, ensuring the stability of the connection end. The support mechanism includes a side frame fixedly connected to one side of the foot pad. Water is introduced through an external hose when the valve body is opened. Water is introduced into the pressure test air chamber at one end of the water inlet pipe through a water meter and the valve body. After being pressurized in the pressure test air chamber, water is discharged through a drain pipe. This effectively reduces the sagging caused by the device connecting to the external hose during the assembly and use of pressure tests in hydrogeological engineering surveys. This also ensures that during long-term use, the connection end is not affected by external force accidental contact or impact force generated during water supply, thus reducing the shaking amplitude caused by the impact force. This improves the confidentiality of the connection and reduces the occurrence of water leakage after loosening.

This invention relates to a compact spring return actuator, and more particularly to an actuator for emergency reset of a valve in the event of an emergency such as a power outage. The actuator is equipped with differential planetary gear reducers in both the drive shaft (operated by a motor) and the working shaft (operated by an elastic body of the emergency reset assembly), and these differential planetary gear reducers are meshed together. This duality allows the power transmission of the motor and the elastic body to be independent of each other, thereby reducing motor capacity and miniaturizing the components of the power transmission system. Ultimately, this results in a compact spring return actuator that is lightweight and miniaturized as a whole. To achieve the objectives described above, the compact spring return actuator of the present invention is characterized by comprising: a drive shaft that receives power from a motor and rotates; a driven shaft that rotates by means of the drive shaft and opens and closes a valve; a reduction assembly that reduces the rotational force transmitted to the driven shaft, including a differential planetary gear reducer mounted on the drive shaft; and an emergency reset assembly equipped with an elastomer and a working shaft that converts the elastic force of the elastomer into a rotational force for transmission and engagement with the differential planetary gear reducer, for rotating and resetting the valve when the power is disconnected.

The invention mainly discloses a reinforced supporting sheet and a foldable display comprising the same, and the reinforced supporting sheet is integrated in the foldable display to be attached to the bottom surface of a display panel and is used for supporting the display panel. According to the invention, the reinforced support sheet comprises a substrate and a corrugation structure, and the top surface of the substrate is used for being attached to and connected with the display panel, so that the corrugation structure covers a bending area of the display panel. According to the design, when the display panel is bent, the corrugation structure buffers stress applied to the bending area, so that residual stress accumulated in the bending area is reduced, and creases and cracks in the bending area are avoided. Due to the fact that the corrugated structure has high strength and rigidity, the display panel can be well supported.
