The application discloses a modular device suitable for liquid oxygen phase change rock breaking and a use method. The device comprises a shape memory type hard plastic pipe, a double-layer flexible film assembly, an aluminum metal input pipe, a spiral copper wire, a bottom packaging cover, a top packaging cover, an axial gradient density cellulose roll paper and an annular differential time ignition assembly. The cellulose roll paper is distributed in a gradient distribution of lower density at the lower part and higher density at the upper part along the axial direction, and the annular differential time sequential ignition forms a "spiral rising type phase change wave chain reaction". An air heat insulation interlayer is arranged between the double-layer film to reduce liquid oxygen evaporation loss and form a secondary air cushion buffer layer. The shape memory type PVC hard pipe is radially self-contracted to form a self-adaptive explosion chamber under the initiation high temperature. The spiral copper wire wound outside the metal input pipe simultaneously realizes electrostatic conduction and redundant ignition when the ignition head fails. Through the synergistic effect of the multiple innovative features, the application realizes the space-time controllable release of the rock breaking energy, prolongs the pressure relief duration by 2-3 times, expands the breaking radius by about 25%, reduces the liquid oxygen evaporation loss to below 8%, and has outstanding substantial features and significant technical progress.

This utility model discloses a portable packaging cardboard box, belonging to the field of packaging cardboard box technology. The cardboard box includes a box body made of corrugated cardboard, with a reinforcing component made of rigid plastic inside. The reinforcing component is glued to the inner wall of the box body with environmentally friendly adhesive. The box body is a square trapezoid with a larger top and a smaller bottom, with the bottom surface smaller than the top surface. The side walls have an angle of 5°-10° with the vertical direction, and the four side walls have the same slope, allowing multiple boxes to be nested and stacked. The reinforcing component includes a top frame, a bottom frame, and side frames.

This utility model provides a lightweight excavator underframe, belonging to the technical field of excavator underframes. It includes a frame body and a top fixing head. The top fixing head is fixedly connected to the top of the frame body, a first connecting head is fixedly connected to the front of the frame body, and a second connecting head is fixedly connected to the back of the frame body. This utility model adds a wear-resistant layer, active electrodes, and connecting wires to the frame body. The wear-resistant layer is made of hard plastic. When the bottom of the frame body comes into contact with the ground, wear occurs preferentially, slowing down the paint peeling rate. The active electrodes preferentially undergo an oxidation reaction, generating electrons, which are then transported to the interior of the connecting wires. The connecting wires then transport electrons to the interior of the frame body, thereby replenishing the entire frame body with electrons, slowing down the corrosion rate and extending the service life of the excavator underframe.
