The invention relates to a molding mold for manufacturing bathroom washbasins, including a molding mold, a docking mold, an isolator, a docking assembly and a sealing body. The number of the molding molds is two, and the middle part of the molding mold is provided with a cavity. The combination of the cavity of the mold corresponds to the structure of the washbasin. The middle, lower, upper and upper ends of the forming mold are respectively provided with a round hole and a forming groove. The upper end of the forming mold is provided with a sprue. The cavities of the molding dies are connected. The present invention can solve the following problems existing in the molding of the existing bathroom washbasin: most of the forming molds are disposable molds, which makes the processing cost of the washbasin too high, and the mold of the washbasin is two forming molds butted, and the forming molds are butted. The accuracy cannot be effectively positioned, which makes the molding effect of the washbasin poor. When the molding mold is pouring the ceramic mixed slurry, the mixed slurry will leak, and the pressure maintaining process cannot be carried out during the forming process of the washbasin.

The invention relates to a service-oriented power distribution network information physical system, consisting of a device layer, a support layer, an application layer and an interface layer, wherein the device layer, the support layer, the application layer and the interface layer are separately communicated to one another through an IEC61968 standard interface; the device layer, the support layer, the application layer and the interface layer can serve as service users. According to the service-oriented power distribution network information physical system provided by the invention, the power distribution network information physical system is integrated based on the encapsulation of components or elements at specific operational levels and aiming at the interfaces and associations of services or the components, and a composite multifunctional application system can be formed through the step-by-step assembly and process planning of application service components.

A dry connection method for a concrete slab of a steel-concrete composite beam and a steel beam, the steps of which are: A, making a positioning template; B, making a steel plate connector: welding the lower end of the shear connector to the connecting plate surface; insert the connecting rod into the positioning hole of the positioning template, temporarily fix the connecting rod and the positioning template, and then fix the connecting rod with the lower surface of the connecting plate, then remove the temporary fixation, and remove the positioning template; C, steel plate connection The connection between the device and the concrete slab: pre-embed the shear connector in the concrete slab; and expose the connecting rod and the connecting slab; D. The connection between the concrete slab and the steel beam: clamp the positioning formwork on the upper flange of the steel beam, and The position of the positioning hole of the positioning template is drilled to connect the through hole; the positioning template is removed; the connecting rod is inserted into the connecting through hole, and finally the connecting rod is fixed on the lower surface of the upper flange plate of the steel beam to form a steel-concrete composite beam. The method can reduce the site construction amount and environmental pollution, and accelerate the construction speed.

The invention discloses a bracket for bagged Escherichia coli test paper. The bracket comprises a base, a press strip and pre-brackets, wherein a fixed anti-slip belt and a V-shaped through hole are arranged at a transverse side surface of the base, the V-shaped through hole is disposed under the fixed anti-slip belt, and the lengths of the holes on both sides of the V-shaped through hole are notequal; the press strip and the pre-brackets are respectively disposed on the fixed anti-slip belt and the V-shaped through hole at the transverse side surface, the press strip is in a recessed shape,two ends of the press strip are connected to the longitudinal side surface of the base, the surface of the press strip facing the fixed anti-slip belt is provided with a moving anti-slip belt, and thepre-brackets are connected by the V-shaped through hole and an elastic connecting mechanism provided on the inner side of the transverse side surface; a strip-shaped through hole is formed at the longitudinal side surface of the base, the strip-shaped through hole includes a horizontal section and a vertical section, and both ends of the press strip are connected by the strip-shaped through holeand the longitudinal side surface. The bracket can reduce the operation steps of operators and reduce the risk of the person being infected by a sample, uses mechanical friction to substitute the operation of human hand, and reduces the risk of sample pollution due to personnel operation.
