The electric heating device of the present invention includes a heating panel, a heating element, a heat insulation component, a fixing shell, a temperature measuring element, and a socket. The heating element is located on the lower side of the heating panel and has a power receiving part. The heat insulation component has a heat insulation cavity with an upper opening for covering the heating element. The fixing shell has a shell cavity with an upper opening for accommodating the heat insulation component, and the upper end of the fixing shell is connected to the heating panel by an adhesive material. The temperature measuring element is installed at the bottom of the heat insulation component. The socket is fixed to the side of the fixing shell and electrically connected to the power receiving part and the temperature measuring element respectively through a power supply wire and a detection wire. The power supply wire is arranged in a power supply groove, and the detection wire is arranged in a detection groove. The interface end of the socket faces the side of the fixing shell. By providing a socket on the fixing shell, external wiring can be quickly connected to the socket of the electric heating device through a plug during assembly. This assembly method is simple, quick, reliable, and interchangeable, achieving modular packaging and good overall product integrity.

This utility model describes a thin wall socket with a storage state and a use state. The thin wall socket includes: a housing with a through hole extending to the outside; a floating member with a socket for inserting an external plug; and a plug assembly for inserting with an external connector. In the storage state, the floating member is located inside the housing, and the plug assembly rotates to be partially retracted into the housing. In the use state, the floating member protrudes from the housing through the through hole, and the plug assembly rotates to extend beyond the housing. In the storage state, the thin wall socket has a relatively small and lightweight size, making it easy for users to carry. When needed, the thickness of the thin wall socket increases to allow the insertion of an external connector, and the plug assembly extends to allow insertion into an external power strip. Therefore, the size of the thin wall socket can be flexibly changed, significantly improving its portability and applicability.

The utility model provides an ultrathin alarm, which relates to the technical field of alarms and comprises a shell and a piezoelectric plate. A first stepped groove is formed in the bottom surface of the shell; a second stepped groove is formed in the groove bottom of the first stepped groove; the first stepped groove and the second stepped groove are coaxially arranged; a sounding hole is formed in the groove bottom of the second stepped groove in a penetrating manner; the groove bottom of the first stepped groove is provided with a positioning convex ring protruding downwards. The piezoelectric plate is placed in the first stepped groove, the upper end face of the piezoelectric plate abuts against the lower end face of the positioning convex ring, the lower end face of the piezoelectric plate is flush with the lower end face of the shell, and the outer circumferential wall of the piezoelectric plate is adhered to the inner circumferential wall of the shell through an adhesive. The ultra-thin alarm has the advantages that the piezoelectric patch is flush with the shell, and an original cover body structure is omitted, so that the structure is simpler, the thickness is lighter and thinner, lead transmission is more convenient, and meanwhile, the production cost of the whole alarm is also greatly reduced.

The application discloses a cavity type prefabricated segment assembled pier top beam and a construction method thereof. The top plate of the pier top beam is divided into a first top plate and a second top plate, the second top plate is located in the middle of the first top plate, the bottom plate is divided into a first bottom plate and a second bottom plate, the second bottom plate is located in the middle of the first bottom plate, the web plate is divided into a first web plate and a second web plate which are mutually attached, the pier top beam structure comprises a shell and an inner cavity part, the shell comprises the first top plate, the first bottom plate, the first web plate and a flange plate, and the shell is a prefabricated reinforced concrete component; the inner cavity part comprises the second top plate, the second bottom plate and the second web plate, and the inner cavity part is a cast-in-situ reinforced concrete structure. The prefabricated shell is light and thin, the prefabricated shell reduces the weight of the prefabricated segment by 30-50% compared with the prefabricated pier top beam, and is convenient for transportation and hoisting; the pier top segment beam has global stability and seismic performance, the wet joint design of the cast-in-situ beam is removed, the installation speed of the segment assembly is ensured, and the longitudinal splicing joint of the beam is reduced, and the safety of the beam is ensured.

Embodiments of the present application disclose a display module and a display device. The display module comprises a driving substrate, a cathode and a touch structure layer. The cathode is arranged on the driving substrate. The touch structure layer is arranged on a side of the cathode layer away from the substrate. The touch structure layer is provided with a first touch electrode and a second touch electrode arranged perpendicularly to each other. When the touch structure layer is subjected to an external pressing force, at least one of the first touch electrode and the second touch electrode is multiplexed as a first pressure sensing electrode, and the cathode is multiplexed as a second pressure sensing electrode. The present application aims to provide a functional layer capable of realizing touch and pressure sensing at the same time, so as to improve the integration of the display module.
