Liquid crystal screen backlight module
ActiveCN222636440URealize snap-in fixationquick changeNon-linear opticsMechanical engineeringMaterials science
The utility model discloses a liquid crystal screen backlight module which comprises an optical film assembly and a structural frame, the periphery of the side face of the optical film assembly is wrapped with a frame, and clamping pieces are fixed to the side face of the frame through screws. According to the utility model, the optical film assembly with the frame is arranged at the periphery of the opening of the structural frame, so that the optical film assembly is attached to the buffer frame adhered to the inner side surface of the structural frame, and in the process, the optical film assembly is pressed; a clamping piece fixed on the side face of the optical film assembly through a screw is made to make contact with a clamping column welded to the inner side face of a structural frame, then the spherical end of the clamping column can penetrate through the clamping piece of a U-shaped structure in the pressed deformation state, and two protruding parts integrally arranged on the inner side face of the clamping piece abut against the surface of the lower portion of the clamping column. Compared with a traditional installation mode that fixed connection is matched with gluing, the optical film assembly fixing device has the advantages that the optical film assembly can be rapidly detached and replaced, and maintenance, disassembly and assembly are convenient.

Automobile exhaust pipe fixing support
ActiveCN224617435URealize snap-in fixation
This utility model belongs to the technical field of exhaust pipe brackets, specifically relating to a fixing bracket for automotive aftertreatment exhaust pipes. It includes an upper clamping plate and a lower clamping plate, with the lower clamping plate located below the upper clamping plate. Fixing plates are fixed to both sides of the lower end of the upper clamping plate. A spring is installed inside the lower end of the fixing plate, and sliding plates are fixed to both ends of the spring inside the fixing plate. The two sliding plates are slidably connected to the fixing plate, and a locking block is fixed to the opposite end of each sliding plate. Communicating grooves are provided on both sides of the upper end of the lower clamping plate. This utility model connects the spring, sliding plates, and locking blocks via the fixing plates on both sides of the upper clamping plate. The lower clamping plate is connected to a threaded rod and a movable plate via a base plate and side plate. Utilizing the matching relationship between the first inclined surface of the locking block and the second inclined surface of the movable plate, combined with the elasticity of the spring, the upper and lower clamping plates are locked together. The position of the movable plate can be adjusted by rotating the threaded rod, allowing for the clamping and fixing of exhaust pipes of different specifications.
