Abstract: A passage barrier includes a frame and a gate engaged in the frame. The four corners of the frame are provided with mounting holes for receiving pressurized fasteners. An adjustment member can be rotated on a rod of the pressurized fastener. The mounting hole and the rod are designed so that the rod can only slide in the mounting hole but cannot rotate. In the installation process, a user is reminded not to press the frame on both sides of the passage by rotating the rod of the pressurized fastener, but to press the frame on both sides of the passage by rotating the adjustment member, so that the user can quickly find the correct the installation method.

Abstract: A pet drinking fountain includes a tank for storing water, a pump arranged in the tank to pump water, a pipe connected to the pump through which the water pumped by the pump flows, and a plate for presenting drinking water to pets disposed above the tank and in fluid communication with the pipe. A tray is arranged between the plate and the tank. Water in the tank is pumped upwards from the pump into the pipe and then flows out to the plate and then overflows into the tank.
