The invention discloses a pressure-resistant liquid storage tank, which comprises a liquid storage tank body and a head arranged at both ends of the liquid storage tank. 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 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.
