This application relates to a pole-mounted integrated distribution box with compensation, belonging to the technical field of smart grids. It includes a box body and a door rotatably mounted on the front side of the box body. The box body has several heat dissipation vents on its left and right sides, a wiring port on its bottom surface, and several lifting rings fixed on its top surface. Protective plates, in a vertically protected state, are detachably installed on the left and right sides of the box body. The protective plates have vertically oriented clearances on their sides facing the box body for dangling cables to pass through. In this application, when the protective plates are in a vertically protected state, they can confine dangling cables within the clearances, forming a physical barrier that effectively prevents accidental contact by the elderly, children, and other people with weak safety awareness, thus avoiding the risk of electric shock at the source and meeting the safety needs of outdoor densely populated scenarios.

This application discloses an embedded outdoor anti-theft parcel delivery port structure, relating to the field of building facility technology. It includes an outer frame for fixed connection to a pre-reserved hole in a wall, with a delivery channel on the outer frame. A door leaf is hinged to the inner wall of the delivery channel.
