And a plurality of limiting clamping grooves are formed in the two side walls in the food area, third partition plates are further installed between the limiting clamping grooves, and the problem that due to the fact that the interior of an existing distribution box is a complete inner cavity, food in the food distribution box is shaken and collided in the transportation process, the food in the food distribution box is collided with one another, and the food in the food distribution box is scattered is solved.

This utility model discloses a corrosion-resistant prestressed concrete pipe pile for soft soil foundations, relating to the field of pile foundation technology. The corrosion-resistant prestressed concrete pipe pile for soft soil foundations includes a pile body, a pile tip, a pile cap, and prestressing tendons. The pile body includes a buffer layer, an anti-corrosion layer, and a steel pipe layer distributed radially from the outside to the inside. A pouring cavity for concrete is formed within the steel pipe layer, and a reinforcing cage is installed within the pouring cavity. The pile tip has a pointed end and a connecting end at opposite ends, connected to the bottom of the steel pipe layer via a connecting plate. The pile cap is connected to the top of the steel pipe layer, and a grouting hole communicating with the pouring cavity is opened on the pile cap. The prestressing tendons are inserted within the reinforcing cage, extending axially along the pile body, and are connected between the pile cap and the connecting plate. The concrete, reinforcing cage, and prestressing tendons form an integrated load-bearing structure, improving the structural strength of the pile body. The buffer layer prevents the anti-corrosion layer from wearing away during pile driving, extending the service life of the pipe pile.

This invention discloses a power fitting fixing device, including a base and a device body. The device body includes a power housing, a connecting block, and two housing anchor points. The connecting block is disposed on the inner wall of the power housing, and the two housing anchor points are symmetrically disposed on the inner wall of the power housing. This invention achieves power steering through a bevel gear, driving a hollow screw, which in turn pushes the clamping assembly. This allows the end locking tongue to generate a large axial locking force that increases non-linearly at the end of its stroke, forming a structural self-locking upon completion of the action. Simultaneously, by integrating a torque-limiting clutch, the final clamping force is precisely anchored at a preset threshold, achieving mechanical standardization of the fastening operation and effectively avoiding human error. This purely mechanical force-amplifying and protective structure not only ensures the long-term durability of the equipment in harsh environments but also significantly reduces on-site construction intensity and maintenance costs through efficient automated operation.
