The utility model discloses an adjustable electrophoretic spraying device which comprises a supporting frame, the supporting frame is connected to external equipment, an adjusting mechanism is arranged on the supporting frame, the adjusting mechanism comprises a transverse plate, a follow-up block, a threaded sleeve, a threaded ring, a fixing rod, a push disc, an attaching disc, a tension spring and a fixing mechanism, the transverse plate is attached to the supporting frame, and the follow-up block is arranged on the transverse plate. A transverse groove is formed in the supporting frame, the follow-up block is clamped in the transverse groove, the adjusting mechanism allows a user to easily adjust the position of the hook through the ingenious design of a transverse plate, the follow-up block, a threaded sleeve, a threaded ring, a fixing rod, a push disc and a tension spring so as to adapt to workpieces of different sizes and shapes, the transverse plate is tightly attached to the supporting frame, and the adjusting mechanism is convenient to use. The stability of the whole mechanism is ensured, the tension spring keeps continuous tension, and it is ensured that the adjusted position is stable and reliable.

This application relates to the field of battery manufacturing technology, and in particular to a quick-change positioning structure for high-precision electrode molds. The structure includes a base, on the top of which a mold assembly is mounted. The mold assembly is installed on the top of the base via a quick-release assembly. This application utilizes components such as a turntable, knob, lead screw, cross-shaped push block, and inclined slider. Through the fixed connection between the turntable and a threaded sleeve, and the threaded engagement between the lead screw and the threaded sleeve, rotating the knob drives the lead screw to move axially, thereby pushing the cross-shaped push block to press against the inclined slider. The acute-angle contact surface design between the inclined slider and the cross-shaped push block converts axial movement into radial movement, causing it to press against the limiting ring of the mold assembly. Therefore, this device allows for quick tightening or loosening of the inclined slider against the mold assembly through simple knob rotation, significantly improving the convenience and efficiency of mold replacement.

The application relates to the technical field of valves, in particular to a top-mounted wear-resistant shear valve which comprises a valve body, a valve cover fixed at the top of the valve body and a shear gate located in a vertical installation cavity in the valve body; the bottom end of the shear gate is provided with a bevel shear blade which is built up with a hard alloy layer, a detachable valve seat with a scraper surface is arranged on the downstream side of a flow passage of the valve body, a longitudinal guide rail matched with the shear gate is arranged on the inner wall of the vertical installation cavity, and a slag discharge groove is arranged at the bottom of the valve body. The top-mounted structure can realize integral hoisting and maintenance of internal components without disassembling pipelines, thereby shortening the maintenance time; the cooperation of the bevel shear blade and the scraper surface can forcibly cut off hard particles in the medium, and the cooperation of the guide rail support and the slag discharge design can significantly improve the wear resistance, sealing tightness and operation reliability of the valve.

The utility model relates to building equipment technical field discloses a kind of building materials transfer equipment for construction site, including bottom plate, the mounting bracket is fixedly connected on bottom plate upper surface, the wheel shaft is arranged on bottom plate lower surface, the walking wheel is rotatably connected in the both ends of wheel shaft, the support frame is symmetrically arranged on the outer wall of bottom plate, the adjusting assembly is arranged on the inner wall of support frame, the adjusting assembly includes slide bar and guide rail one, the outer wall of guide rail one is fixedly connected in the inner wall of support frame, the inner wall of slide bar is slidably connected in the outer wall of guide rail one, the auxiliary wheel is arranged on the lower surface of slide bar.In the utility model, by operating hydraulic rod drive slide bar sliding, adjusting auxiliary wheel height to change transfer bucket gravity center, while slide bar sliding drives connecting rod one and connecting rod two to make hand push rod angle automatically adapt auxiliary wheel height, to improve the slope transfer stability and security, simultaneously optimize hand push rod angle to improve push and pull comfort, improve practicality.
