Q-SJLJG type "Mechanical design parts" showcase I. Overview: mechanical design showcase parts, is based on the mechanical design (parts) the basic requirements of curriculum design and manufacture of laboratory equipment. Showcase by mechanical or physical part model, with the corresponding graphic information basics, vividly show and explain the mechanical design, enhance students' generic types of mechanical parts, structural characteristics and perceptual awareness of design, in order to further study the mechanical designed to lay the foundation. Second, the technical specifications (1) a full showcase composed by 18 single showcase, showcase Body Dimensions: 1200 × 530 × 1900㎜; scale ratio ergonomic design requirements; (2) showcase body with 1.0mm cold rolled steel spray production, cabinet rigidity, elegant appearance; cabinet display panel for super-luxury aluminum sandwich panels, bearing good; (3) showcase the name printed on the upper cabinet for easy identification; (4) cabinet top cover plate built with fluorescent lighting, fluorescent implicit within ergonomic design requirements; the lower part (5) has a cabinet cabinet box for easy storage of a single model, the experimental box and documents related experiments. (6) The cabinet has a back door, favorable maintenance of equipment and easy maintenance. (7) The bottom of the tank with casters for easy mobility. Third, the showcase has the following characteristics: Advanced (1) design. The showcase required mechanical basic courses teaching reform, according to "create the physical textbook, students create a practice environment and to promote self-awareness," the basic idea to optimize the design, so that the "knowledge, cognition, thinking," Trinity, supporting curriculum understanding of the experiment set up to promote curricular construction. (2) demonstrate comprehensive. The showcase with national planning materials as a basis for mechanical design course content for a more comprehensive exhibition, including mechanical coupling, mechanical transmission, shaft components, lubrication and sealing, etc., offers a wealth of knowledge of mechanical design. Different versions of the same name on materials compatibility; Advanced (3) production process. The showcase according to national standards and showcase enterprise standard mechanical design and manufacturing, production of advanced technology, stable product quality, reliable performance and long service life; (4) green design. The showcase use of environmentally friendly materials, machinery operation without noise; electrical safety; make pleasant design; able to adapt to the requirements of modern green lab.
