The invention discloses a structure of an electronic product casing and a processing technology thereof. The structure and processing technology of the electronic product casing fully combine a composite composite material with the advantages of high strength, thin thickness, light weight, corrosion resistance, good radiation resistance and the like. The material panel and the plastic parts with the characteristics of light texture and easy structural processing are realized by injection molding on the surface of the composite material panel through the intermediate film medium layer, and the purpose of fixing the composite material panel and the plastic part is achieved. The electronic product casing with the composite material panel as the outer surface of the casing and the plastic part as the structural member makes the electronic product casing not only retain the good radiation protection effect of the composite material panel, high strength, thin thickness, light weight, corrosion resistance, resistance It has the advantages of high temperature and beautiful appearance, and also forms plastic parts with complex structure through the film dielectric layer and injection molding process, which overcomes the defect that the composite material panel cannot form complex structural parts.

The head at one end of the liquid storage tank is provided with a liquid inlet hole, and the tank wall of the liquid storage tank body is Both the direction and the circumference satisfy the sine wave curve equation. The invention also discloses the manufacturing method of the pressure-resistant liquid storage tank, which mainly adopts the forming method of water injection and pressurized bulging. excellent.

The invention discloses a rear test bed structure of a motorcycle shifting fork checking fixture. The structure is characterized in that a whole rear test bed is cylindrical and is fixed to a bottom plate, the upper end face of the rear test bed is provided with a shifting fork stress shaft test vertical groove right towards the direction of a shifting fork assembly hole test shaft, the rear test bed under the shifting fork stress shaft test vertical groove is provided with a shifting fork stress shaft test annular groove along the circumferential direction, and the bottom of the shifting fork stress shaft test vertical groove at the upper end of the rear test bed is provided with a locating through hole arranged downward. The rear test bed structure can achieve test and locating of a shifting fork locating shaft twice, and the locating does not interfere with each other. The rear test bed structure can achieve test of a plurality of parameters of the shifting fork through match with a front test bed, and meanwhile has the advantages of being convenient to install and locate, convenient to process, capable of lowering processing loss and the like.

The invention relates to a method and a device for detecting the elasticity modulus of corn stalks, which belong to the technical field of modern agricultural equipment. The invention adopts a cantilever beam as a theoretical model, external force is horizontally applied to corn stalks with fixed roots, and the calculation formula of the elasticity modulus of the stalks is calculated according torelevant mechanical principles; according to the measurement principle, a relevant measurement device is designed; and during measurement, the external force with a horizontal action is applied to the corn stalks by a push rod, the corn stalks are bent, the applied external force is transformed by a sensor, an automatic display instrument and the like to display the numerical value of the elasticity modulus of the corn stalks, and the numerical value of the stress intensity of the corn stalks obtained by measurement can be used as one parameter for a corn seed breeding expert to select and breed high-quality corn. The invention has simple operation, scientific measurement principle, reliable measurement result, simple structure and low production cost.

The invention discloses a structure of an electronic product enclosure panel and a manufacturing process thereof. In the invention, metal with characteristics of good radiation protection effect, high strength, high-temperature resistance and the like, and plastic cements with characteristics of light weight, convenience of structure machining and the like are fully combined to realize injection molding on the metal surface through an intermediate medium hot melt adhesive membrane, so that a purpose of fixing and combination of a metal panel and a plastic element is reached, and an electronic product enclosure panel using the metal panel as the enclosure external surface and using the plastic element as the structural element is manufactured, therefore, the electronic product enclosure panel has the advantages of good radiation protection effect, high strength, corrosion resistance, high-temperature resistance, attractiveness, light weight, convenience for machining and the like and can manufacture complex structural elements and the like.

The invention discloses a recirculating double-wire screwing device, comprising a base mechanism and a rotating mechanism. The base mechanism includes a pressure-bearing bracket and a positioning inner cylinder. A first through hole is opened in the middle of the pressure-bearing bracket, and the positioning inner cylinder is fixed connected to the lower end surface of the pressure bearing bracket outside the first through hole; the rotating mechanism includes a rotating outer cylinder and a rotating handle, the rotating handle is connected to the lower end of the rotating outer cylinder, and the outer ends of the rotating outer cylinder on both sides of the rotating handle are respectively provided with There are a first wire hanging buckle slot and a second wire hanging buckle slot; a rotating auxiliary component is arranged at the connection end of the positioning inner cylinder and the pressure bearing bracket, and a toggle rod is connected to the inner end of the rotating outer cylinder; After the cylinder sleeve is positioned outside the inner cylinder, the rotating outer cylinder is connected with the rotating auxiliary assembly through a toggle rod. When the machine is used to screw the steel wire of the fixed formwork, the damage of the original components and the steel wire is reduced, the material is saved, and the safety is higher. Especially when looking up and working at a high place, the effect of screwing is better, and the workers work more efficiently. Effortless.
