Description

Technical Field

[0001] This utility model relates to the field of scale model technology, and more specifically, to a scale model. Background Technology

[0002] Libra is an important teaching tool and is widely used in various scenarios. However, existing Libras generally have a relatively simple structure, which greatly limits their application in diverse teaching and entertainment activities.

[0003] From a pedagogical perspective, existing balance scale designs are often too simplistic, lacking sufficient interactivity and operability. In traditional teaching models, teachers typically only use the balance scale for simple specific gravity measurements, with students passively receiving knowledge and lacking opportunities for active participation and exploration. This teaching method not only fails to stimulate students' learning interest but also hinders the development of their hands-on skills and innovative thinking. Therefore, we propose an improved balance scale model. Utility Model Content

Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] For an example, please refer to... Figures 1-6A balance scale model includes a base structure 3 and a main beam structure 1 mounted on the base structure 3. The main beam structure 1 includes a support member with a long pin 104. Two crossbeams 105 are connected to the outer surface of the long pin 104, and each of the two crossbeams 105 is connected to a tray suspension structure 2. A main beam body 108 is provided between the two tray suspension structures 2 and the main beam structure 1. A first V-shaped rod 107 is connected to the main beam body 108, and both ends of the first V-shaped rod 107 are rotatably connected to the support member. A pointer 109 is provided at the top of the main beam body 108, and the support member is also provided with a mechanism that cooperates with the pointer 109. The scale plate 110 used, through its modular structure including the main beam structure 1, tray suspension structure 2, and base structure 3, not only achieves structural diversity but also provides rich possibilities for assembly and disassembly, meeting users' needs for innovation and variation in the Libra structure. This design makes the Libra suitable for more diverse teaching and entertainment activities, enhancing user participation and experience, and improving the interactivity and operability of the Libra. This not only stimulates students' learning interest but also cultivates their hands-on skills and innovative thinking, adding more fun and challenges to teaching and entertainment activities.

[0033] Furthermore, such as Figures 1-5 As shown, the support includes two first support plates 101. The outer surface of the long pin 104 is inserted into the two first support plates 101. Each of the two first support plates 101 has a first sector-shaped groove 106. The two ends of the first V-shaped rod 107 are respectively inserted into the two first sector-shaped grooves 106. A first baffle 115 is installed on the side of the two first support plates 101 that is far apart from each other. The first baffle 115 can limit the end of the first V-shaped rod 107 to reduce the first V-shaped rod 107 from passing through the first sector-shaped groove 106. The cooperation between the first V-shaped rod 107 and the first sector-shaped groove 106 can limit the rotation stroke of the main beam body 108.

[0034] Furthermore, such as Figures 1-3 As shown, a first limiting plate 103 is provided above the two first support plates 101, and a first connecting plate 102 is fixedly installed on the top of each of the two scale plates 110. The outer surfaces of the two first connecting plates 102 are inserted into the first limiting plate 103. The scale plate 110 is installed on one of the first connecting plates 102, and the top of the pointer 109 passes through the first limiting plate 103. The first limiting plate 103 and the first connecting plate 102 cooperate with each other to reinforce the top of the two first support plates 101.

[0035] Furthermore, such as Figures 1-4As shown, a second limiting plate 117 is placed between the two scale plates 110. Two first insertion ports 116 are opened on each of the two first support plates 101. A first insertion plate 118 is fixedly connected to both ends of the two second limiting plates 117. The outer surface of the first insertion plate 118 is inserted into the inner wall of the first insertion port 116. The second limiting plate 117 is connected to the first support plate 101 through the first insertion plate 118 and the first insertion port 116, which can strengthen the connection between the two first support plates 101.

[0037] Furthermore, such as Figure 2 As shown, a second bolt 114 is provided at the bottom of the main beam body 108, and a first bolt 111 is provided at both ends of the main beam body 108. A fixing plate 112 is sleeved between the first bolt 111 and the end of the main beam body 108. A plurality of nuts 113 for fixing the fixing plate 112 are threadedly connected to the outer surface of the first bolt 111.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the base structure 3 includes a first base plate 301 located at the bottom of two first support plates 101.

An eighth socket 304 and a ninth socket 305 are provided on both the second base plate 302 and the first base plate 301. The outer surface of the second socket 119 is inserted into the eighth socket 304. A fourth limiting plate 309 located below the first base plate 301 is inserted into the inner wall of the second socket 120. The arc-shaped plate 303 and the eighth socket 304 are bonded together on both sides. The connection between the main beam structure 1 and the base structure 3 can be achieved through the insertion of the second socket 119 and the eighth socket 304. After the fourth limiting plate 309 is inserted into the second socket 120, it can limit the position of the second socket 119 after it is inserted into the eighth socket 304.

The pallet suspension structure 2 includes two second support plates 202. Both second support plates 202 are connected to the outer surface of the short pin 122. Both second support plates 202 are provided with second sector grooves 203. A second V-shaped rod 204 is inserted between the two second sector grooves 203. The outer surface of the second V-shaped rod 204 passes through the main beam body 108. The two second support plates 202 are connected to a second baffle 211 on the side that is far away from each other. The position of the second baffle 211 corresponds to the position of the second sector groove 203. The cooperation between the second V-shaped rod 204 and the second sector groove 203 can limit the rotation stroke of the second support plate 202.

[0041] Furthermore, such as Figures 1-3 As shown, each of the two second support plates 202 has several fourth insertion ports 207. A second connecting plate 205 and a third connecting plate 208 are provided between the two second support plates 202.

The top of the third connecting plate 208 is inserted into the seventh insertion port 216. The first tray plate 212, the second tray plate 213 and the retaining ring 214 are bonded together with double-sided adhesive.

[0043] Except for the first bolt 111, nut 113, second bolt 114, long pin 104, and short pin 122, all other components in this application are made of wood as the main structural material, which not only reduces production costs but also meets environmental protection requirements, reflecting an emphasis on sustainable development; the limiting sleeve 123 is made of rubber, and the other metal components include the first bolt 111, nut 113, second bolt 114, long pin 104, and short pin 122;
