Description

Technical Field

[0001] The utility model relates to the technical field of teaching aids for three-dimensional teaching display, in particular to an expandable three-dimensional teaching display cabinet. Background Art

[0002] Teaching aids are a general term for various instruments used to enable students to understand the teaching content intuitively and vividly, as well as the tools used by teachers when teaching. Teaching aids can increase students' interest in learning, enrich perceptual knowledge, help form clear concepts, and develop students' observation and thinking abilities.

[0003] For teaching content with complex structures, if the complex structures can be displayed to students with the help of 3D stereoscopic structure display devices, it will be of great help to students in understanding the teaching content and effectively improve the teaching quality. However, the existing teaching equipment can only display a single three-dimensional sample structure and cannot realize the decomposition and display of the three-dimensional structure, or can only use expensive 3D stereoscopic projection equipment for virtual display and use software to realize the display of 3D effects and the display of the decomposed state of the structure. The investment cost is high and it is difficult to achieve for schools without profitability, which seriously restricts the popularization of 3D stereoscopic display and decomposition structure display teaching adjustment, and the defects are obvious. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an expandable three-dimensional structure teaching display cabinet which can not only display the 3D structure, but also fully display the connection structure of each component after decomposing the three-dimensional structure.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: an expandable three-dimensional teaching display cabinet. The expandable three-dimensional teaching display cabinet comprises a cabinet body, a cabinet door arranged at the front side of the cabinet body and connected to the cabinet body, a window hole is opened on the front side of the cabinet door, and a movable support assembly is installed in the cabinet body. The number of the support assemblies is at least four, and the support assembly comprises a base fixed in the cabinet body and a first support arm movably installed on the base, a second support arm movably hinged to the first support arm, and an adjustment rod connected to the outer end of the second support arm.

[0006] Preferably, the base is a vertical pole fixed vertically in the cabinet, at least four support assemblies share one vertical pole, and the inner ends of the first support arms of at least four support assemblies are movably sleeved on the vertical pole.

[0007] Preferably, there are two upright poles, which are respectively close to the left and right sides of the cabinet, and each upright pole is provided with at least three first support arms.

[0008] Preferably, a pivot shaft is mounted on the outer end of the first support arm, and the inner end of the second support arm is movably connected to the pivot shaft.

[0009] Preferably, the inner end of the adjustment rod is movably connected to the outer end of the second support arm via a ball head connector.

[0010] Preferably, a telescopic rod is movably mounted on the outer end of the second support arm, and the ball head connector is fixed to the outer end of the telescopic rod.

[0011] The beneficial effect of the utility model is that the utility model provides an expandable three-dimensional teaching display cabinet. In practical applications, the various components of the demonstration sample to be displayed are fixedly installed at the ends of the adjustment rods of different support components. The height of the adjustment rod is adjusted by adjusting the installation position of the first support arm on the vertical pole in each support component. The horizontal position of the height of the adjustment rod is adjusted by adjusting the installation angle of the first support arm on the vertical pole and the angle between the second support arm and the second support arm, thereby realizing the positioning of the adjustment rod at any position in the display cabinet space. The design of at least four support components can independently support and display multiple components of the demonstration sample, and display them close to or assembled together according to the connection relationship between the various components of the demonstration sample. Since the position of the adjustment rod can be adjusted arbitrarily, the assembly and disassembly state of the various components in the demonstration sample is realized, which is convenient for students to display the detailed assembly relationship between the various components of the sample, improves the teaching quality, and is highly practical.

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0017] like Figures 1 to 4As shown, a three-dimensional teaching display cabinet that can be unfolded includes a cabinet body 1, a cabinet door 2 arranged at the front side of the cabinet body 1 and connected to the cabinet body 1, a window hole is opened on the front side of the cabinet door 2, and a movable support assembly 3 is installed in the cabinet body 1. The number of the support assemblies 3 is at least four. The support assembly 3 includes a base fixed in the cabinet body 1 and a first support arm 31 movably installed on the base, a second support arm 32 movably hinged to the first support arm 31, and an adjustment rod 33 connected to the outer end of the second support arm 32.

[0018] Specifically, the base is a vertical pole 34 fixed vertically in the cabinet 1 , at least four support assemblies 3 share one vertical pole 34 , and the inner ends of the first support arms 31 of at least four support assemblies 3 are movably sleeved on the vertical pole 34 .

[0019] In practical applications, the various components of the demonstration sample to be displayed are fixedly installed at the ends of the adjustment rods 33 of different support assemblies 3, and the height of the adjustment rod 33 is adjusted by adjusting the installation position of the first support arm 31 in each support assembly 3 on the vertical rod 34. The horizontal position of the height of the adjustment rod 33 is adjusted by adjusting the installation angle of the first support arm 31 on the vertical rod 34 and the angle between the second support arm 32 and the second support arm 32, thereby realizing the positioning of the adjustment rod 33 at any position in the display cabinet space. The design of at least four support assemblies 3 can independently support and display multiple components of the demonstration sample, and display them close together or assembled together according to the connection relationship between the various components of the demonstration sample. Since the position of the adjustment rod 33 can be adjusted arbitrarily, the assembly and disassembly state of the various components in the demonstration sample is realized, which is convenient for students to show the details of the assembly relationship between the various components of the sample, improves the teaching quality, and is highly practical.

[0023] In this embodiment, a telescopic rod 37 is movably installed at the outer end of the second support arm 32, and the ball head connector 36 is fixed to the outer end of the telescopic rod 37. The telescopic rod 37 is used to further increase the comprehensive arm span length of the support assembly 3, and the adjustable space range is larger, the degree of freedom is higher, and the practicality is stronger.
