This utility model discloses a sealed food storage container, including a container body, a lid that fits with the container body, and a flexible sealing ring. The lid is a downward-opening cover structure. An annular groove with the opening facing downwards is provided around the outer edge of the container body's opening. The upper part of the sealing ring is embedded in the annular groove, while the lower part of the sealing ring protrudes outside the annular groove, sealing with the inner wall of the lid when the lid is placed on the container body's opening. This sealed food storage container achieves a seal while preventing the sealing ring from contacting the food inside the container, thus effectively preventing food stains from remaining on the sealing ring and preventing contamination of the food inside the container. Therefore, frequent disassembly and cleaning of the sealing ring is unnecessary, reducing the user's maintenance burden. Furthermore, since the edge of the lid and the sealing ring are not located within the internal space of the container body, the container body can achieve a larger effective volume with the same external dimensions, fully accommodating food and improving its internal space utilization.

This utility model relates to a single-cavity pull-cord sensor, which includes a housing, a winding wheel disposed within the inner cavity of the housing, a measuring component, and a coil spring. The internal space of the winding wheel is divided into an upper concave cavity and a lower concave cavity by a horizontally arranged partition. The measuring component is placed in the upper concave cavity, and the coil spring is placed in the lower concave cavity. Compared with the prior art, this utility model has the advantages of compact structure, small size, and high space utilization.

This utility model discloses a fireproof and explosion-proof box for high-voltage cable joints, comprising two boxes connected at one end by a hinge and at the other end by a locking mechanism. Multiple honeycomb panels and reinforcing plates are provided on both sides of each box, with adjacent honeycomb panels and reinforcing plates staggered and fixed. Elastic clamping mechanisms are provided on opposite side walls of the box. Through-holes are provided at both ends of each box, with two through-holes on the same side corresponding to each other. This utility model can evenly distribute the impact force generated by an explosion across the entire explosion-proof box shell, preventing excessive local stress from causing the shell to crack. This significantly improves the overall strength and stability of the explosion-proof box, effectively reducing the impact of explosions on cable joints and the surrounding environment. Furthermore, it can quickly send signals when abnormal pressure or temperature occurs, alerting maintenance personnel to take appropriate measures to prevent further escalation of the accident, thus improving the safety and reliability of the power system.
