Description

Technical Field

[0001] This utility model relates to the field of splicing model technology, and in particular to a road and bridge design splicing model. Background Technology

[0002] Architectural and environmental art models exist between two-dimensional drawings and actual three-dimensional space, organically linking the two. They are a three-dimensional model that helps refine design creation, can intuitively reflect design intentions, and make up for the limitations of drawings in terms of expression. They are not only part of the designer's design process, but also a form of design expression, and are widely used in municipal construction.

[0003] However, traditional road and bridge assembly models mostly cannot adjust their height, often requiring reassembly, which is time-consuming and significantly reduces worker efficiency. Furthermore, it prevents the disassembly of components from the model panels. Therefore, this paper provides a road and bridge design assembly model to address the problems mentioned in the background. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a road and bridge design assembly model, which aims to improve the existing technology that cannot adjust the height of the road and bridge assembly model. It often requires the model to be reassembled before adjustment, which is very time-consuming and greatly reduces the work efficiency of the staff. In addition, it is impossible to disassemble the parts on the model plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge design splicing model, including a model bridge plate. Fixed seats are provided on both lower sides of the model bridge plate. A threaded rod is rotatably connected inside the fixed seat. A bevel gear one is fixedly connected to the lower outer side of the threaded rod. A bevel gear two is meshed with the left side of the bevel gear one. A rotating shaft is fixedly connected to the outer side of the bevel gear two. A rotating block is fixedly connected to the left side of the rotating shaft. A lifting cylinder is threadedly connected to the upper outer side of the threaded rod. A support plate is fixedly connected to the upper part of the lifting cylinder. The support plate is fixedly connected to both lower sides of the model bridge plate. An mounting plate is fixedly connected to the lower part of the fixed seat. Fixing nails are installed at the four corners inside the mounting plate. A disassembly assembly is provided on the upper part of the model bridge plate. The disassembly assembly is used to disassemble the components on the upper part of the model bridge plate.

[0006] Furthermore, the disassembly assembly includes a mounting base, which is fixedly connected to the upper part of the model bridge plate. The mounting base has a support column inside and a mounting groove inside. A sliding plate is slidably arranged inside the support column. A spring is provided at the rear of the sliding plate. The rear of the spring is fixedly connected to the inner wall of the support column. A locking block is fixedly connected to the front of the sliding plate. A locking hole is provided on the inner wall of the mounting base. Guardrail plates are fixedly installed on the inner sides of the two support columns on the same horizontal plane.

[0007] Furthermore, the model bridge plate has extension plates on both sides inside, sliding grooves on both sides inside, several slots inside the extension plates, and insert rods on both sides inside.

[0008] Furthermore, the extension plate is slidably connected inside the groove.

[0009] Furthermore, the insertion rod is slidably connected inside the slot.

[0010] Furthermore, a transparent water tank is fixedly installed on the lower middle side of the model bridge plate.

[0011] Furthermore, the lifting cylinder is slidably connected inside the fixed base.

[0012] Furthermore, the card block is slidably connected inside the card hole.

[0022] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a road and bridge design splicing model, including a model bridge plate 9. Fixed seats 3 are provided on both sides of the lower part of the model bridge plate 9. A threaded rod 5 is rotatably connected inside the fixed seat 3. A bevel gear 7 is fixedly connected to the lower outer side of the threaded rod 5. A bevel gear 8 is meshed with the left side of the bevel gear 7. A rotating shaft 24 is fixedly connected to the outside of the bevel gear 8. A rotating block 4 is fixedly connected to the left side of the rotating shaft 24. A lifting cylinder 6 is threadedly connected to the upper outer side of the threaded rod 5. A support plate 12 is fixedly connected to the upper part of the lifting cylinder 6. The support plate 12 is fixedly connected to both sides of the lower part of the model bridge plate 9. An mounting plate 1 is fixedly connected to the lower part of the fixed seat 3. Fixing nails 2 are installed at the four corners inside the mounting plate 1. A disassembly assembly is provided on the upper part of the model bridge plate 9. The disassembly assembly is used to disassemble the components on the upper part of the model bridge plate 9.

[0024] The mounting plate 1 is installed in the designated position by fixing nail 2. The two rotating blocks 4 are rotated, and the rotating blocks 4 drive the rotating shaft 24 to rotate. The rotating shaft 24 drives the second bevel gear 8 to rotate. Because the second bevel gear 8 and the first bevel gear 7 are meshed, the second bevel gear 8 drives the first bevel gear 7 to rotate. The first bevel gear 7 drives the threaded rod 5 to rotate. The threaded rod 5 drives the lifting cylinder 6 to rotate and move upward, so that the lifting cylinder 6 drives the model bridge plate 9 to move upward, and the height can be adjusted.

[0025] Reference Figure 1 and Figure 3 The disassembly assembly includes a mounting base 11, which is fixedly connected to the upper part of the model bridge plate 9. A support column 14 is provided inside the mounting base 11, and a mounting groove 19 is opened inside the mounting base 11. A sliding plate 17 is slidably arranged inside the support column 14. A spring 16 is provided at the rear of the sliding plate 17, and the rear of the spring 16 is fixedly connected to the inner wall of the support column 14. A locking block 13 is fixedly connected to the front of the sliding plate 17. A locking hole 18 is opened on the inner wall of the mounting base 11. Guardrail plates 15 are fixedly installed on the inner sides of the two support columns 14 on the same horizontal plane.

[0026] By pressing the locking block 13, the locking block 13 causes the sliding plate 17 to compress the spring 16, inserting the support column 14 into the mounting groove 19 inside the mounting base 11, so that the locking block 13 is engaged inside the locking hole 18, and the guardrail 15 is spliced ​​and installed, which facilitates the disassembly and splicing of the model, and at the same time improves the aesthetics of the road and bridge.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The model bridge plate 9 has extension plates 10 on both sides inside, and slide grooves 20 on both sides inside. The extension plates 10 have several slots 22 inside, and insert rods 21 on both sides inside. The extension plates 10 are slidably connected to the inside of the slide grooves 20, and the insert rods 21 are slidably connected to the inside of the slots 22. A transparent water tank 23 is fixedly installed on the lower middle side of the model bridge plate 9. The lifting cylinder 6 is slidably connected to the inside of the fixed base 3, and the locking block 13 is slidably connected to the inside of the locking hole 18.

[0028] By pulling out the insert rod 21, the extension plate 10 slides inside the slide groove 20. When it moves to the designated position, the insert rod 21 is inserted into the designated slot 22 for fixation, thus lengthening the model bridge plate 9 to meet different teaching needs. The extension plate 10 can be lengthened by sliding inside the slide groove 20, and the length of the extension plate 10 can be fixed by sliding inside the slot 22. The transparent water tank 23 is set to facilitate observation of whether the model is balanced and prevent tilting. The height of the device can be adjusted by sliding the lifting cylinder 6 inside the fixed base 3, and the support column 14 can be fixed by sliding the locking block 13 inside the locking hole 18.

[0029] Working principle: When using this device, the mounting plate 1 is installed in the designated position using the fixing nails 2. Rotating the two rotating blocks 4 causes the rotating shaft 24 to rotate, which in turn drives the second bevel gear 8 to rotate. Because the second bevel gear 8 is meshed with the first bevel gear 7, the second bevel gear 8 drives the first bevel gear 7 to rotate, which in turn drives the threaded rod 5 to rotate. The threaded rod 5 then drives the lifting cylinder 6 to rotate and move upwards, causing the lifting cylinder 6 to move the model bridge plate 9 upwards, thus adjusting the height. Simultaneously, the user can observe the model's balance through the transparent water tank 23 to prevent tilting. By pressing the locking block 13, the locking block 13 causes the sliding plate 17 to compress the spring 16, inserting the support column 14 into the mounting groove 19 inside the mounting base 11, so that the locking block 13 is engaged inside the locking hole 18, and the guardrail plate 15 is spliced ​​and installed, which facilitates the disassembly and assembly of the model and improves the aesthetics of the road and bridge. At the same time, the insert rod 21 is pulled out, so that the extension plate 10 slides inside the slide groove 20. When it moves to the designated position, the insert rod 21 is inserted into the designated slot 22 for fixation, thus extending the model bridge plate 9 to meet different teaching needs.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
