Description

Technical Field

[0001] The utility model belongs to the technical field of models, and in particular relates to a bridge model component. Background Art

[0002] A bridge model is a scaled-down version of a building erected on rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. There are many types of bridge models, the most common of which are beam bridge models and arch bridge models. A beam bridge model is the most basic type of bridge, consisting of one or more beams spanning over supports. It has the characteristics of simple structure and convenient construction, but limited bearing capacity. An arch bridge model is a bridge composed of a series of interconnected arc structures. Its main advantage is its strong bearing capacity, and it is suitable for crossing rivers or valleys with larger spans.

[0003] At present, most bridge models are displayed directly on the table. When people observe the overall picture of the bridge model, they need to move around the bridge model to observe the complete bridge model, and the display effect is poor. In addition, in order to prevent the bridge model from moving during display, the staff also need to use screws and other fixing components to fix the bridge model, which results in a long time for the staff to disassemble and assemble the bridge model. The bridge model may also be damaged during the disassembly process, and the disassembly and assembly is inconvenient. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example

[0027] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0028] A bridge model assembly comprises a bridge model body 1, a base 2 is arranged below the bridge model body 1, a rotating structure 3 is arranged inside the base 2, a mounting plate 4 is arranged above the base 2, support rods 5 are fixed to the left and right sides of the top of the mounting plate 4, a display stand 6 is bolted to the top of the support rods 5, a positioning structure 7 is fixed above the mounting plate 4, positioning blocks 8 are slidably connected to the four corners of the top of the display stand 6, and a groove is provided on the surface of the positioning block 8, a connecting plate 9 is fixed to the bottom of the bridge model body 1, and the connecting plate 9 is used in conjunction with the groove on the surface of the positioning block 8, and light strips 10 are installed on the front and back sides of the top of the display stand 6.

[0029] The rotating structure 3 includes a driving motor 31, a first timing pulley 32, a second timing pulley 33 and a rotating column 34. The driving motor 31 is fixed to the right side of the top of the base 2, and the output shaft of the driving motor 31 passes through the inside of the base 2. The first timing pulley 32 is rotatably connected to the right side of the inside of the base 2, and the output shaft of the driving motor 31 is fixedly connected to the first timing pulley 32. The second timing pulley 33 is rotatably connected to the middle part of the inside of the base 2. The diameter of the first timing pulley 32 is smaller than the diameter of the second timing pulley 33, and the first timing pulley 32 passes through The timing belt is connected to the second timing pulley 33 by transmission, and the rotating column 34 is arranged through the top of the base 2, and the bottom end of the rotating column 34 is fixedly connected to the top of the second timing pulley 33, and the top of the rotating column 34 is fixed to the bottom of the mounting plate 4. When the bridge model body 1 is displayed, the driving motor 31 below is turned on, so that the first timing pulley 32 rotates, so that the second timing pulley 33 on one side rotates slowly, thereby driving the rotating column 34 above to rotate, so that the mounting plate 4 moves, and the bridge model body 1 above is rotated and displayed.

[0030] The positioning structure 7 includes an electric push rod 71, a lifting block 72, a connecting rod 73, a slider 74 and a slide groove 75. The electric push rod 71 is fixed to the middle part of the top of the mounting plate 4, the lifting block 72 is fixed to the top of the output shaft of the electric push rod 71, the connecting rod 73 is hinged to the surface of the lifting block 72, the slider 74 is hinged to the end of the connecting rod 73 away from the lifting block 72, the slide groove 75 is opened on the surface of the display stand 6, the lifting block 72 is distributed at the four corners of the lifting block 72, the slider 74 is located inside the slide groove 75 and is slidably connected to the inner wall of the slide groove 75, and the bottom of the positioning block 8 is fixedly connected to the slider 74. When the staff opens the electric push rod 71, the output shaft of the electric push rod 71 pushes the upper lifting block 72 to move up and down, thereby making the connecting rods 73 on the four sides move, so that the positioning block 8 above the display stand 6 moves synchronously, so as to fix or release the bridge model body 1.

[0031] Limiting grooves 11 are provided on both sides of the inner wall of the slide groove 75, and limiting blocks 12 are fixed on the surfaces of both sides of the slider 74.

[0032] A protective pad 13 is bonded to the inner wall of the groove on the surface of the positioning block 8, and the surface of the protective pad 13 is in contact with the surface of the connecting plate 9. The material of the protective pad 13 is rubber. Through the provision of the protective pad 13, when the positioning block 8 positions the bridge model body 1, the positioning block 8 can be prevented from causing damage, and the positioning effect of the bridge model body 1 can be improved to prevent the bridge model body 1 from falling off from the display stand 6.

[0033] Working principle: When displaying the bridge model body 1, the staff first takes out the bridge model body 1 and moves it to the top of the display stand 6, and then the staff opens the electric push rod 71 below, so that the output shaft of the electric push rod 71 contracts, and the lifting block 72 drops accordingly, and the connecting rods 73 on the four sides are activated, so that the positioning block 8 moves, and the connecting plate 9 below the bridge model body 1 is clamped by the positioning block 8 to complete the installation operation of the bridge model body 1. After the installation is completed, the staff turns on the light strips 10 on both sides and the driving motor 31 below, so that the upper bridge model body 1 can be rotated, and the upper bridge model body 1 can be rotated for display.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
