Description

Technical Field

[0001] This utility model relates to the field of industrial scanner equipment technology, and in particular to a connection mechanism for large format scanners. Background Technology

[0002] In the design and production of large-format industrial scanners, various materials are typically used, such as: various plastic materials, including ABS, PC, and HIPS; various metal materials, including iron, aluminum, stainless steel, and copper; and other non-metallic materials. These materials all have different physical properties, especially different coefficients of thermal expansion and contraction.

[0003] Therefore, when a scanner is used in an environment with large temperature differences, components made of different materials will undergo different thermal expansion and contraction deformations. Furthermore, the large dimensions of large-format industrial scanners along their length amplify this phenomenon. Since scanners require high precision, the cumulative effects of these factors can lead to decreased performance, poor quality, and even loss of basic functionality. Utility Model Content

A nut is provided on the top of the movable connecting screw, and the preload spring is wound around the movable connecting screw between the upper sliding washer and the nut. This allows the scanner upper frame base plate to slide slightly under the action of the movable connecting screw and the movable connecting groove. Thus, the movable connecting assembly enables the scanner upper frame body and the scanner upper frame base plate to slide relative to each other in the X direction, be relatively fixed in the Y direction, and achieve elastic expansion and contraction of preload and overload in the Z direction.

[0008] In a preferred embodiment of this utility model, five sets of movable connecting components are provided on the upper frame base plate of the scanner.

[0011] In a preferred embodiment of the present invention, a limiting cavity is provided on the bottom plate of the upper frame of the scanner to cooperate with the upper sliding pad, and the movable connecting groove is provided on the bottom surface of the limiting cavity.

[0012] In a preferred embodiment of this invention, the limiting cavity and the movable connecting groove are waist-shaped structures.

[0013] In a preferred embodiment of this utility model, the fixing ring is an E-type ring.

[0014] The beneficial effects of this utility model are: by cooperating with the fixed connection component and the movable connection component, the product can reduce or avoid the problem of deformation of product parts caused by internal stress due to the different length changes of different materials during thermal expansion and contraction when transported, stored and used under different temperature conditions.
