This utility model discloses a prefabricated fiberglass meter well, relating to the technical field of fiberglass meter wells. It includes a base, a lower well body, an upper well body, and a cover. The base has an installation groove with a raised water guide pipe on the bottom surface of the groove. The water guide pipe has a water inlet on its side wall. The bottom of the lower well body sits within the installation groove, and its bottom surface has an insertion hole corresponding to the water guide pipe. The water guide pipe is inserted into the insertion hole, and the water inlet on the water guide pipe is located inside the lower well body. A positioning component is connected to the water guide pipe, which presses the bottom wall of the lower well body tightly into the installation groove. The upper well body is detachably connected to the lower well body, and its top has a well opening. The cover is fastened to the well opening. This utility model uses prefabricated components for on-site assembly, greatly shortening the construction period and reducing the impact of construction on the environment and traffic. The design of the water inlet not only solves the drainage problem, but the overall structure combines drainage and assembly structures, making assembly more convenient.

This utility model relates to a mechanical structure for locking a side door from inside a cabinet. It includes a base, a rocker arm, a pivot screw, fasteners, and a side door connecting plate. The base is fixed inside the cabinet side door via a bottom slot. The pivot screw is fixed to the rocker arm via a groove, forming a sliding lever structure. The side door connecting plate engages with the head of the rocker arm via a square hole. By screwing in the fastener and pushing the tail of the rocker arm, the longitudinal pressure is converted into a lateral pressing force on the side door connecting plate by the head of the rocker arm, achieving concealed locking. The innovative design of this utility model lies in the fact that all components are built into the cabinet, with no exposed locking structure, improving safety and aesthetics. The fasteners and rocker arm work together to achieve linear adjustment of the locking force, adapting to complex working conditions such as vibration and temperature differences. This device has a simple structure and low cost, solving the problems of exposed and easily damaged traditional cabinet door locks and inconvenient adjustment. It is particularly suitable for outdoor equipment with high protection requirements, such as DC charging piles.
