Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of laboratory cabinet door panels, and in particular to a double-hole hinge fixing piece for laboratory cabinet door panels. Background Technology
[0002] Laboratory cabinet doors are the movable panel sections installed on the front of laboratory cabinets. They are typically made of specific materials such as metal, wood, or plastic, possessing a certain level of strength and durability to meet the needs of laboratory use. The doors are connected to the cabinet frame via hinges or other connectors, allowing them to be opened and closed for access to items inside the cabinet. The design of the doors may also take into account aesthetics, corrosion resistance, and ease of cleaning. In some laboratory furniture, the doors may also have special functions, such as fire resistance, explosion-proof properties, and corrosion resistance.
[0003] In existing technologies, the conventional method for fixing hinged door panels is to fix them with screws to the inner door panel, while the outer door panel is clamped and fixed with through holes. The inner and outer door panels are generally connected by snap-fit. Due to assembly process requirements, this structure requires a pre-existing assembly gap and indirectly fixes the outer panel, which can easily lead to door sagging. In addition, if one end rubs against the bottom, it can easily damage the painted surface and cause rust. Therefore, it is necessary to design a double-hole hinge fixing piece for laboratory cabinet door panels to solve the above problems.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
