This utility model discloses a magnetic charging base for walkie-talkies, relating to the field of charging technology for wired communication equipment. It includes a base assembly, and a magnetic head assembly is used for charging the walkie-talkie. The magnetic head assembly is connected to a control box assembly via a plug cable. The end face of the base assembly has a charging interface, a groove, and an anti-slip liner, while the end face of the magnetic head assembly has a charging port, a magnetic surface, and a protrusion. This magnetic charging base for walkie-talkies uses a magnetic connection for charging through the cooperation of the charging interface, charging port, and magnetic surface. It utilizes magnetic force to achieve a fast and stable connection, eliminating the need for cumbersome physical plugging operations, making operation simple and convenient. Simultaneously, the mechanical interlocking of the groove and protrusion assists the magnetic connection, and the high-friction anti-slip liner forms a three-dimensional anti-slip mechanism, solving the problem of insufficient stability in traditional magnetic charging and achieving a multi-dimensional anti-displacement effect.

This invention relates to the technical field, specifically a method for laying a flexible, intelligent hydrogen transmission pipeline that enables rapid installation. The pipeline includes a polyethylene pipe, the outer side of which is covered with a second adhesive layer. The polyethylene pipe and the second adhesive layer are bonded together by a fiberglass tape reinforcing layer. The outer side of the second adhesive layer is covered with a first adhesive layer, and the second adhesive layer and the first adhesive layer are bonded together by an aluminum foil layer. The first adhesive layer is then covered with a polyethylene pipe protective sleeve. This invention avoids secondary excavation of the pipeline, does not damage existing roads and facilities, does not harm urban green spaces, avoids road congestion caused by construction, utilizes existing or abandoned pipelines, allows for rapid installation, requires fewer personnel, is unaffected by weather, and shortens the construction period.

The application belongs to the field of antimicrobial materials, and discloses an antibacterial bioactive coating and a preparation method thereof. The application converts β-cyclodextrin into a dialdehyde derivative through periodic acid oxidation, and copolymerizes the dialdehyde derivative with acrylated chitosan under the initiation of ultraviolet light free radicals to prepare an intelligent copolymer which can be specifically cut by β-cyclodextrinase. Natural plant polyphenols are loaded in the copolymer to realize enzyme-triggered precise release and maintain long-acting antibacterial activity. After coating, the solvent is removed, the micropores are closed, and the molecular-level secondary crosslinking is completed in one step under the treatment of supercritical CO2 environment at 35 MPa and 40 DEG C for 2 hours. Traditional high-temperature drying is not needed, internal stress and crack generation are significantly reduced, and the stability of the pores is improved. The final coating has self-repairing, high adhesion and scrub resistance, and the preparation process is environmentally friendly and efficient, and is suitable for the surface long-acting antibacterial protection of medical devices, food packaging and public facilities.

This utility model discloses a tilting core-pulling mold, including an upper mold plate and a lower mold plate. An upper mold core is installed inside the upper mold plate, and a lower mold core is installed inside the lower mold plate. In-mold screws connect the upper mold plate and the upper mold core, and the lower mold plate and the lower mold core. A product forming cavity is formed between the upper and lower mold cores. A hydraulic cylinder is installed on the outside of the lower mold plate. The drive end of the hydraulic cylinder is connected to a slider guide seat. An tilting groove is provided on the slider guide seat, and a tilting slider core is slidably connected to the tilting groove. The upper end of the tilting slider core is inserted into the product forming cavity. This tilting core-pulling mold is designed for die-casting products with tilted structures. By using a hydraulic cylinder to control the tilting slider core to tilt at a certain angle, the tilted structure of the product is not damaged during demolding, and the internal structure of the mold is saved, reducing the manufacturing cost of the mold.

The present application relates to a kind of positive sheet packing, laminated sheet, finished product conveying collaborative process, comprising the following steps: step 1: in the process of plate conveying mechanism, positive sheet feeding, positive sheet bag packing, positive sheet stacking after packing are completed in plate conveying process;Step 2: after packing plate falls, negative sheet adsorption transfer mechanism is transferred to the plate group stacking mechanism above negative sheet, negative sheet falls to packing plate, and the staggered stacking of negative sheet and packing plate is realized by circulation work, and plate group is formed;Step 3: finished product output mechanism realizes the turnover of plate group and plate group is transported to next process vertically.This application is small in overall volume, and occupies less space, and is easy to place;High degree of automation, realize automatic feeding, automatic feeding, automatic packing, automatic stacking into plate group, automatic discharge of fully automated operation.
