Abstract
Description
Technical Field
[0001] This application relates to the field of sand table technology, specifically a sand table for architectural planning and design. Background Technology
[0002] In the field of architectural planning and design, model sand tables are important tools for showcasing building layouts, spatial structures, and environmental designs.
[0003] In the prior art, Chinese utility model patent with authorization announcement number CN215814794U discloses a real estate building planning and design model sand table that can be raised and lowered for storage. This solution realizes the raising and lowering of the sand table through a drive motor and a lead screw mechanism, uses an electric telescopic rod to adjust the height of the house model to adapt to the storage space, and uses silicone cushioning pads to reduce collision damage. It effectively solves the problems of dust pollution, inconvenient storage, and collision damage of traditional sand tables, and significantly improves the protective performance of the sand table.
[0004] However, in practical applications, to enhance the display effect, the sand table usually needs to be equipped with lighting fixtures (such as architectural lighting, ambient lighting, etc.). The lifting and storage structure of the sand table will cause the wires of the lighting fixtures to move frequently with the sand table. During the lifting and lowering process, the wires are prone to stress concentration due to pulling and bending, which will lead to poor contact at the joints, resulting in problems such as flickering, going out, or even circuit failure.
[0005] Therefore, this application provides an architectural planning and design model sand table to solve the above problems. Utility Model Content
[0006] This application provides an architectural planning and design model sand table, which aims to solve the problems mentioned in the background art, such as the lighting wiring being prone to poor contact or circuit failure due to pulling and bending during the lifting and storage of existing sand tables.
[0007] To achieve the above objectives, this application provides the following technical solution: an architectural planning and design model sand table, comprising a base, a box mounted on the base, and a model sand table body disposed at the end of the box away from the base. The box is provided with a storage mechanism for storing the model sand table body. The storage mechanism includes a frame that moves axially on the box, a driving component disposed on the box for driving the frame to move closer to or away from the base, and a dustproof cover disposed at the end of the frame away from the base. Through the cooperation of the height-adjustable frame and the dustproof cover, the model sand table body achieves both dustproof storage and enclosure protection. During storage, the frame can be raised above the model height using the driving component, and then the dustproof cover can be closed to effectively isolate dust. During display, the frame can be adjusted to a suitable height to form a fence surrounding the model, reducing damage from external collisions and improving the practicality and protection of the sand table.
[0008] Preferably, to avoid affecting the viewing experience of the model, both the frame and the dust cover are made of transparent material. This ensures that the model sandbox maintains good visual appeal even when stored, allowing clear observation of model details without removing the dust cover, thus balancing dust protection and display effectiveness, and avoiding the impact of traditional obstructive storage structures on the viewing experience.
[0009] Preferably, to facilitate height adjustment of the frame, the driving component includes threaded sleeves rotatably disposed at four opposite corners within the housing and penetrating the main body of the model sand table; a threaded rod threadedly inserted into the threaded sleeves and fixedly connected to the frame; and a drive motor for driving the threaded sleeves to rotate. The threaded transmission mechanism achieves stable lifting and lowering of the frame, with high precision, low noise, and a simple and reliable structure, facilitating height control and meeting storage and display needs in different scenarios.
[0010] Preferably, to ensure synchronous rotation of the four threaded sleeves: a synchronous gear is fixedly fitted on each threaded sleeve; a synchronous toothed belt meshes with each of the four synchronous gears; a secondary gear meshing with the synchronous toothed belt is rotatably mounted inside the housing; a primary gear meshing with the secondary gear is rotatably mounted inside the housing; and a drive motor is mounted above the primary gear via a bracket. The output shaft of the drive motor passes through the bracket and is fixedly connected to the shaft of the primary gear. This gear-belt transmission system achieves synchronous rotation of the four threaded sleeves, requiring only one drive motor to drive the frame's smooth lifting and lowering, reducing the number of motors used, lowering costs and energy consumption, and avoiding frame tilting problems caused by asynchronous operation of multiple motors.
[0011] Preferably, to facilitate the opening and closing of the dust cover component: the dust cover component includes baffles symmetrically arranged on the frame, and the baffles are hinged to the frame. Two rubber posts are symmetrically fixedly connected to the baffles. The hinged baffles and rubber posts design enables convenient opening and closing of the dust cover component and provides cushioning protection, avoiding the baffles occupying extra space during opening and closing, while also reducing impact noise and structural damage during the flipping process.
[0012] Preferably, to reduce the gap between the cover and the frame, a U-shaped sealing strip is fixedly connected to one side of the cover near the frame. The U-shaped sealing strip fills the gap between the cover and the frame, improving the sealing performance of the dust cover and effectively preventing dust and moisture from entering the model storage space, thus enhancing the protective effect of the sand table.
[0013] This application achieves a dual function of dustproof storage and enclosure protection for the model sand table through the combination of an adjustable-height frame and a dustproof cover. When storing, the frame can be raised above the model's height using a drive mechanism, and then the dustproof cover can be closed to effectively isolate dust. When displaying, the frame can be adjusted to a suitable height to form a fence surrounding the model, reducing damage from external collisions and enhancing the sand table's practicality and protection.
[0014] This application achieves convenient opening and closing of the dust cover and provides cushioning protection through the design of the hinged baffle and rubber pillar, avoiding the baffle from occupying extra space when opening and closing, and reducing impact noise and structural damage during the flipping process.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0021] Example 1
[0022] This embodiment provides an architectural planning and design model sand table, such as Figure 1-3As shown, the model sand table includes a base 1, a box 2 mounted on the base 1, and a model sand table body 3 located at the end of the box 2 away from the base 1. The box 2 is equipped with a storage mechanism 4 for storing the model sand table body 3. The storage mechanism 4 includes a frame 41 that moves axially on the box 2, a drive component 42 mounted on the box 2 for moving the frame 41 closer to or away from the base 1, and a dust cover 43 located at the end of the frame 41 away from the base 1. Through the cooperation of the height-adjustable frame 41 and the dust cover 43, the model sand table body 3 achieves both dustproof storage and enclosure protection. During storage, the drive component 42 can be used to raise the frame 41 above the model's height, and then the dust cover 43 can be closed to effectively isolate dust. During display, the frame 41 can be adjusted to a suitable height to form a fence surrounding the model, reducing damage from external collisions and improving the sand table's practicality and protection. When the drive unit 42 is working, it adjusts the height of the frame 41. When it is necessary to store the model sand table body 3, the frame 41 is raised to a height higher than the model on the model sand table body 3, and then the dust cover 43 is closed to form a closed space to block dust. When the model is in the display state, the drive unit 42 adjusts the frame 41 to a suitable height around the model so that it acts as a fence to physically protect the model.
[0023] To ensure unobstructed viewing of the model, both the frame 41 and the dust cover 43 are made of transparent material. This ensures that the model sandbox body 3 maintains good viewing even when stored, allowing clear observation of model details without removing the dust cover, thus balancing dust protection and display effectiveness, and avoiding the impact of traditional obstructive storage structures on the viewing experience. Since both the frame 41 and the dust cover 43 are made of transparent materials (such as acrylic or glass), when the dust cover 43 is closed on the frame 41, the transparent material does not obstruct the model sandbox body 3, allowing users to directly observe the internal model through the transparent structure, achieving a "stored without blocking light" display effect.
[0024] To facilitate height adjustment of the frame 41, the drive unit 42 includes threaded sleeves 421 rotatably mounted at four opposite corners within the housing 2 and penetrating the model sand table body 3; a threaded rod 422 threadedly inserted into the threaded sleeves 421 and fixedly connected to the frame 41; and a drive motor 423 for driving the threaded sleeves 421 to rotate. The threaded transmission mechanism achieves stable lifting and lowering of the frame 41, with high precision, low noise, and a simple and reliable structure. It facilitates control of the frame 41's height, meeting storage and display needs in various scenarios. When the drive motor 423 starts, it drives the threaded sleeves 421 to rotate. Since the threaded rod 422 is threadedly connected to the threaded sleeves 421 and fixed to the frame 41, the rotation of the threaded sleeves 421 causes the threaded rod 422 to move axially (inward or outward), thereby driving the frame 41 to rise and fall, achieving height adjustment.
[0025] To ensure synchronous rotation of the four threaded sleeves 421: Synchronous gears 424 are fixedly mounted on the threaded sleeves 421, and synchronous toothed belts 425 mesh with the four synchronous gears 424. A secondary gear 426, meshing with the synchronous toothed belts 425, is rotatably mounted inside the housing 2. A primary gear 427, meshing with the secondary gear 426, is rotatably mounted inside the housing 2. A drive motor 423 is mounted above the primary gear 427 via a bracket, and the output shaft of the drive motor 423 passes through the bracket and is fixedly connected to the shaft of the primary gear 427. This gear-belt transmission system achieves synchronous rotation of the four threaded sleeves 421. Only one drive motor 423 is needed to drive the frame 41 to rise and fall smoothly, reducing the number of motors used, lowering costs and energy consumption, and avoiding the tilting problem of the frame 41 caused by asynchronous operation of multiple motors. The output shaft of the drive motor 423 drives the main gear 427 to rotate. The main gear 427 meshes with the secondary gear 426, driving the secondary gear 426 to rotate. The secondary gear 426 is connected to four synchronous gears 424 through a synchronous toothed belt 425, so that the synchronous toothed belt 425 drives the synchronous gears 424 to rotate synchronously, thereby driving the four threaded sleeves 421 to rotate synchronously, ensuring that the threaded rods 422 rise and fall synchronously, and realizing the smooth movement of the frame 41.
[0026] Example 2
[0027] Unlike Embodiment 1, to facilitate the opening and closing of the dust cover component 43, the dust cover component 43 includes baffles 431 symmetrically arranged on the frame 41, and the baffles 431 are hinged to the frame 41. Two rubber posts 432 are symmetrically fixedly connected to the baffles 431. Through the design of the hinged baffles 431 and rubber posts 432, the dust cover component 43 can be easily opened and closed and is provided with cushioning protection, avoiding the baffles 431 occupying extra space when opening and closing, and reducing impact noise and structural damage during the flipping process. The baffle 431 is hinged to the frame 41. When the dust cover 43 needs to be unfolded, the baffle 431 is flipped around the hinge end to the side of the frame 41 by holding the rubber post 432 (e.g., flipped upwards 270°) to complete the unfolding. The rubber post 432 is set at the movable end of the baffle 431. When the baffle 431 is flipped into place, the rubber post 432 contacts the frame 41 and absorbs the impact force through elastic deformation to avoid rigid collision.
[0028] To reduce the gap between the cover plate 431 and the frame 41, a U-shaped sealing strip 433 is fixedly connected to one side of the cover plate 431 near the frame 41. The U-shaped sealing strip 433 fills the gap between the cover plate 431 and the frame 41, improving the sealing performance of the dust cover 43 and effectively preventing dust and moisture from entering the model storage space, thus enhancing the protective effect of the sand table. When the cover plate 431 is placed on top of the frame 41, the U-shaped sealing strip 433 (such as made of rubber) on the side of the cover plate 431 is inserted into the port of the frame 41. The elastic deformation of the U-shaped structure tightly conforms to the inner wall of the frame 41, eliminating the gap between them and forming a sealed structure to prevent external pollutants from entering.
[0029] The wiring diagram of the drive motor 423 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the drive motor 423 will not be explained in detail.
[0030] The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
[0031] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.
[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
