This utility model discloses an environmentally friendly and impact-resistant battery pack transport packaging structure, including two side packaging blocks. Each side packaging block has a placement groove. The two ends of the battery pack are respectively placed into the placement grooves on the two side packaging blocks. An upper packaging plate is placed on the battery pack and located between the placement grooves on the two side packaging blocks. The two side packaging blocks, the battery pack, and the upper packaging plate are placed together in an outer packaging box. This utility model, with side packaging blocks, an upper packaging plate, and an outer packaging box, uses the placement grooves on the two side packaging blocks and the upper packaging plate to surround and fix the battery pack. Then, the two side packaging blocks, the battery pack, and the upper packaging plate are placed together in the outer packaging box, realizing the overall packaging of the battery pack. This effectively avoids the problem of squeezing and breaking or crushing of the battery pack during transportation, improves the transport packaging effect of the battery pack, and thus improves the transport reliability and safety of the battery pack.

This utility model relates to the field of mung bean cake packaging technology, and more particularly to a mung bean cake packaging with a preservation function. The technical solution includes: a packaging box, the packaging box including a box bottom, side panels rotatably disposed on both the left and right sides of the box bottom, a box lid rotatably disposed on the side of the two side panels that are far apart from each other, a box body disposed on the top surface of the box bottom, a buffer layer disposed inside the box body, and a preservation box disposed inside the buffer layer, the preservation box including a second box lid and a second box body. This utility model, by incorporating a humidity regulating bag, can absorb excess moisture inside the packaging, controlling the humidity within a suitable range, preventing the mung bean cake from becoming moldy and spoiled due to dampness, and can also reduce the oxygen content inside the packaging, further inhibiting the growth of microorganisms. The packaging box and buffer layer provide good compressive strength, effectively preventing external pressure from compressing and damaging the mung bean cake inside.

This utility model discloses a temperature and humidity control warehouse for storing premium soybeans, including a chassis, a placement compartment, and a temperature and humidity control mechanism. The outer compartment of the placement compartment is inserted into the chassis, and the top of the reinforcing frame on its inner wall is equipped with hooks, allowing for overall loading and unloading via hoisting equipment. The perforated panels inside the placement frame are used to stack bagged premium soybeans. The temperature and humidity control mechanism includes a humidification ring pipe and a heat dissipation cover. The humidification ring pipe supplies water through an inlet pipe, and nozzles spray humidification. A fan inside the heat dissipation cover works with a ventilation filter to create air circulation, maintaining stable temperature and humidity within the warehouse. This warehouse achieves rapid loading and unloading of large quantities of premium soybeans through mechanized hoisting, improving loading and unloading efficiency, reducing labor costs, and ensuring a constant temperature and humidity environment within the warehouse, reducing the impact of temperature and humidity fluctuations on the quality of the premium soybeans. It is suitable for storing premium soybeans.

This invention provides a gripping device for removing cards from a card slot, relating to the field of card storage production and processing technology. It includes a robotic arm, an upper gripper block, a tensioning spring, and a lower gripper block. The upper gripper block is fixedly mounted at the end of the robotic arm, and the lower gripper block is rotatably mounted at the end of the robotic arm and located below the upper gripper block. One end of the tensioning spring is fixedly connected to the lower gripper block, and the other end is fixedly mounted at the end of the robotic arm or on the upper gripper block. The front ends of both the upper and lower gripper blocks have wedge-shaped structures with a guiding function. The tensioning spring maintains a constant clamping state between the upper and lower gripper blocks. This invention avoids the damage caused by excessive card compression due to excessive force in traditional devices, reduces gripping failures caused by misaligned or slightly deformed cards in the card slot, and minimizes paper jams caused by simultaneously gripping multiple cards. The device is smaller and less expensive.

This invention relates to the field of cutting equipment technology and discloses a fixed-length cutting device for glass tube processing based on laser cutting. A laser is bolted to one side of the worktable, and a positioning component is provided on one side of the upper end of the worktable. A hydraulic rod and a driving component are fixedly installed inside the worktable, and a fixed-length component is provided at one end of the hydraulic rod. The fixed-length component includes a collar rotatably connected to the hydraulic rod. Multiple sets of conveying mechanisms are symmetrically arranged on the inner wall of the collar, and a cleaning component is provided on one side of the collar. The conveying mechanism includes an elastic element connected to the inner wall of the collar. A roller is sleeved in the middle of the outer wall of the elastic element, and clamping components are provided on both sides of the outer wall of the elastic element. This realizes fully automated batch processing of fixed-length feeding, rotary cutting, resetting cleaning, and fixed-length feeding, reducing manual intervention.

This utility model relates to the field of road engineering technology and discloses a frost heave and differential settlement control structure suitable for culvert sections in cold regions. The structure, from top to bottom, includes a roadbed, a fill matrix, a stepped aggregate layer, a stepped high-strength foamed concrete layer, and a culvert. A main drainage pipe is inclinedly arranged in the aggregate layer, and lateral drainage pipes are provided on both sides of the roadbed slopes to drain moisture from the roadbed. The high-strength foamed concrete layer is laid above and on both sides of the culvert, providing good thermal insulation to address freezing issues exacerbated by wind tunnel effects, and buffering the frost heave force of the surrounding soil to prevent direct frost heave force from causing compression damage to the culvert structure. This structure forms a multi-level stiffness transition from flexible to semi-rigid along the culvert transition section of the roadbed, reducing differential settlement and misalignment risks at the connection between the culvert and the roadbed, improving the overall stability of the roadbed and driving safety. The overall structure is reliable, easy to construct, and suitable for widespread application in cold regions.

This disclosure discloses an electronic device and its assembly method. The electronic device includes a housing, an earpiece, a display assembly, and a sealing structure. The housing includes a connected mid-frame and a mid-plate. The mid-plate has a through hole. The earpiece is connected to the mid-plate and faces the through hole. The display assembly includes a connected structural reinforcement and a display portion. The structural reinforcement is connected to the mid-frame, and a gap is formed between them. The sealing structure includes a connected first part and a second part. The first part is connected to the mid-plate and the display portion, respectively. The second part is connected to the mid-frame, the display portion, and the structural reinforcement, respectively, and is elastic. A sound outlet channel is formed between the sealing structure, the display portion, the mid-frame, and the mid-plate. The sound outlet channel communicates with the gap and the through hole. In this disclosure, it is not necessary to provide an earpiece decorative piece between the mid-frame and the display portion, which reduces the possibility of the sealing structure compressing and damaging the display portion, thereby reducing the thickness of the electronic device at the earpiece location.
