This utility model relates to a differential pressure gauge mounting structure for a static pressure chamber. A differential pressure gauge is installed on the left side of the static pressure chamber shell near the top. The gauge is mounted on a mounting plate, which is then connected to a mounting recess in the static pressure chamber shell via the mounting plate. The gauge dial is mounted on the front side of the mounting plate, and the gauge body passes through a through hole and a rear guide housing before extending into the static pressure chamber shell. Positioning grooves are provided on both sides of the mounting recess, and positioning protrusions matching these grooves are provided on both sides of the rear side of the mounting plate. This utility model first mounts the differential pressure gauge on the mounting plate, then mounts the entire structure onto the static pressure chamber. This ensures timely replacement and maintenance of the gauge regardless of whether the panel has an inspection window.

A glass lifter adjustable guide rail, including guide rail body for cooperating with slide plate, both ends of the guide rail body are provided with pulley matched with driving rope, both ends of the guide rail body are provided with connecting hole compared with the outside of pulley, the connecting hole is used for cooperating with the corresponding position of door to form the fixation between guide rail body and door, further including adjusting column threaded connected with connecting hole, the adjusting column is provided with fastening platform and fastening nut, the corresponding end surface of fastening platform and fastening nut is matched with both sides of door respectively to form the fixation between adjusting column and door, one end of the adjusting column protrudes from the outside of door and is provided with operating hole at the side end part.The beneficial effects of the utility model are: the technical scheme realizes the adjustability of guide rail body in the thickness direction of door through the threaded connection of adjusting column and connecting hole and the cooperation of fastening platform and fastening nut, thereby improving the convenience of installation and maintenance.

This invention discloses a surface coating modification process for fast-charging graphite anode materials, belonging to the field of surface coating modification of graphite anode materials. The process includes the following steps: Graphite pretreatment: Natural spherical graphite or artificial graphite is selected as raw material and ball-milled for 3-8 hours. An appropriate amount of dispersant can be added to prevent graphite particle agglomeration. The ball-milled graphite particles are then acid-washed using a 10%-30% hydrochloric acid or sulfuric acid solution. This invention effectively removes impurities and defects from the graphite surface and increases the specific surface area and surface active sites of the graphite particles by precisely controlling the graphite pretreatment conditions, such as appropriate ball-milling time, acid concentration, and temperature. Simultaneously, a gradient coating structure is adopted, with multiple coatings using phenolic resin ethanol solutions of different mass fractions. Combined with conductive additives such as carbon nanotubes and graphene, as well as the introduction of metal salts, a more complete conductive network is constructed.
