Description

Technical Field

[0001] This utility model relates to the field of floor heating display platform technology, specifically a display platform for dry-laid floor heating structure principle. Background Technology

[0002] Underfloor heating, a comfortable heating system hidden under the floor, creates a warm environment through even heat dissipation. To allow people to intuitively understand its intricate structure, underfloor heating display platforms have emerged. This specially designed platform is not for actual experience or stepping on; its core function is to clearly dissect the structure of underfloor heating. It presents the hidden underfloor heating layers (such as insulation layers, heat equalization layers, coils, and radiator panels) in a three-dimensional and cross-sectional manner, like an enlarged teaching model. Through it, users can clearly see the heat transfer path, material composition, and working principle of underfloor heating at a glance.

[0003] Underfloor heating demonstration platforms serve as static, visual windows for understanding the core technologies of underfloor heating, combining educational, marketing, and interactive experiences. However, they still have certain limitations: 1) Traditional models use fixed, glued sections or manually disassembled modules, failing to dynamically simulate the reverse separation logic of the underfloor heating structure from the surface to the underground, resulting in rigid layering and poor interactivity; 2) Existing devices only present the physical structure, lacking demonstrations of the actual heat transfer process (e.g., relying on static graphics or LED lighting simulations), making it impossible to verify the working principle of the underfloor heating system: "heat source generation → pipe heat transfer → heat storage layer diffusion," leaving the demonstration at a superficial level. Therefore, in response to these shortcomings, there is an urgent need to develop a dry-laid underfloor heating structure principle demonstration platform to overcome current deficiencies and meet current needs. Utility Model Content

[0004] The purpose of this utility model is to provide a platform for demonstrating the structural principle of dry-laid underfloor heating, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a platform for demonstrating the structural principle of dry-laid underfloor heating, including a cabinet;

[0006] Storage boxes fixed to the cabinet;

[0007] The underfloor heating display unit can be stored in a storage box or raised and unfolded from the storage box; the underfloor heating display unit includes:

[0008] The graded lifting shaft is composed of at least two lifting shaft sections with successively increasing outer diameters, which are fixedly connected along the axial direction, with the difference in outer diameter between adjacent lifting shaft sections being 1-5mm;

[0009] The display modules are stacked in multiple layers, from bottom to top including a concrete layer display module, a dry-laid underfloor heating module, a composite insulation layer display module, a heat storage layer display module, a floor tile display module a, and a floor tile display module b; among them, the concrete layer display module, the dry-laid underfloor heating module, the composite insulation layer display module, the heat storage layer display module, the floor tile display module a, and the floor tile display module b are each provided with through holes that penetrate their thickness;

[0010] The inner diameter of the through hole of each display module is matched with the outer diameter of the corresponding section of the lifting shaft in the graded lifting shaft, and the inner diameter of each through hole decreases from bottom to top.

[0011] The outer diameter of the bottommost lifting shaft section of the tiered lifting shaft is the largest, and the inner diameter of the through hole of the matching display module is the largest. The outer diameter of the topmost lifting shaft section of the tiered lifting shaft is the smallest, and the inner diameter of the through hole of the matching display module is the smallest.

[0012] The lifting seat is fixedly connected to the bottom end of the grading lifting shaft and is used to drive the grading lifting shaft to move up and down.

[0013] The glass is fixedly connected to the top of the staged lifting shaft;

[0014] The lifting drive assembly is installed inside the cabinet and connected to the lifting base, and is used to drive the lifting base and the stepped lifting shaft fixed thereto to lift.

[0015] In practical use, when the lifting drive assembly drives the lifting seat and the tiered lifting shafts to rise, the lifting shaft d of the tiered lifting shafts first lifts the floor tile display modules a and b, whose apertures are equal to those of the lifting shaft e. As the lifting height increases, the next level, the second largest outer diameter lifting shaft c, lifts the heat storage layer display module, whose aperture is equal to that of the lifting shaft d. This process continues until the bottommost largest outer diameter lifting shaft a lifts the concrete layer display module, whose aperture is equal to that of the lifting shaft b. This achieves the sequential separation and unfolding of all the stacked display modules through tiered lifting. The aperture matching design of the shaft and the stacked display modules utilizes the characteristic that the outer diameter of the lifting shaft section gradually decreases from bottom to top. This allows the upper-layer modules to be lifted first during the lifting process, and the lower-layer modules to be separated sequentially downwards. Ultimately, this achieves a reverse decomposition display that exposes the surface decoration layer to the underground structural layer layer by layer. This not only intuitively simulates the logic of real underfloor heating profile inspection, but also replaces the complex transmission mechanism with the precise matching of the shaft shoulder and aperture. This ensures the stable separation of each layer of modules while greatly simplifying the structure, reducing the failure rate, and significantly improving the display efficiency and immersive experience of the dry-laid underfloor heating layering principle.

[0016] Preferably, the graded lifting shaft is composed of five lifting shafts a, b, c, d, and e with successively smaller outer diameters, which are fixedly connected along the axial direction, and the difference in outer diameter between adjacent lifting shaft segments is 2 mm.

[0017] In practical use, this tolerance value can ensure that each lifting shaft section (such as lifting shaft b, lifting shaft c, etc.) and the through hole of the corresponding display module (such as the through hole of the concrete layer display module and the dry-laid underfloor heating module) form a precise sliding clearance fit, avoiding jamming or shaking. It can also clearly separate the six-layer stacked modules (from the concrete layer display module to the floor tile display module b) within a limited stroke through a small outer diameter difference (2mm), achieving precise control of the height difference of each layer, while reducing the processing accuracy requirements and manufacturing costs.

[0018] Preferably, the concrete layer display module, the dry-laid underfloor heating module and the composite insulation layer display module, the heat equalization and heat storage layer display module, the floor tile display module a and the floor tile display module b are stacked sequentially from bottom to top; the inner diameter of the through hole of the concrete layer display module is equal to the outer diameter of the lifting shaft b, the inner diameter of the through hole of the dry-laid underfloor heating module and the composite insulation layer display module is equal to the outer diameter of the lifting shaft c, the inner diameter of the through hole of the heat equalization and heat storage layer display module is equal to the outer diameter of the lifting shaft d, and the inner diameter of the through hole of the floor tile display module a and the floor tile display module b is equal to the outer diameter of the lifting shaft e.

[0019] In practical use, by precisely matching the outer diameter of the through holes of the display modules with the corresponding shaft segments of the graded lifting shafts, while ensuring that the reverse inspection logic of prioritizing the separation of the surface decorative layer (floor tile display modules a / b) and exposing it layer by layer to the concrete base layer is strictly followed when lifting from bottom to top, the functionally related layers (dry-laid underfloor heating modules and composite insulation layer display modules) are set to have the same hole diameter and are lifted synchronously by the same shaft segment (lifting shaft c). This reduces the number of shaft segments, simplifies the structure, and maintains the integrity between layers in actual engineering. With the synergistic effect of precision tolerances and guide shafts, the horizontal offset of the modules is effectively eliminated, and the precise positioning and stable separation of the six-layer modules are achieved in a limited space.

[0020] Preferably, the lifting seat includes: an internally threaded sleeve that is threadedly engaged with the output end of the lifting drive assembly; at least one guide shaft that is fixed between the lifting seat and the glass and slidably engaged with a guide hole provided on the cabinet or storage box, and the guide shaft sequentially passes through the concrete layer display module, the dry-laid underfloor heating module and the composite insulation layer display module, the heat storage layer display module, the floor tile display module a and the floor tile display module b, and slidably engages with them.

[0021] In practical use, the lifting seat achieves vertical lifting drive through the screw thread engagement of the internal threaded sleeve and the lifting drive component. At the same time, a rigid support frame is formed by at least one guide shaft that runs through all display modules (from the concrete layer display module to the floor tile display module b) – one end of which is fixed to the lifting seat and the other end to the glass. The guide shaft slides with the guide hole on the cabinet or storage box to constrain the horizontal degree of freedom of the lifting seat, and simultaneously passes through the through hole of each layer of display module to form a sliding pair. The guide shaft also has a keyway structure along the axial direction to prevent the deflection of each display module. When the tiered lifting shaft performs layered lifting, it works together to suppress the radial offset and torsion of the modules, ensuring that the six-layer modules always remain vertically aligned and stably separated during the lifting process.

[0022] Preferably, the composite insulation layer display module is equipped with a floor heating reflective film and wire mesh; the dry-laid floor heating module is equipped with an oxygen-resistant floor heating pipe; the heat storage layer display module is equipped with a plastic pipe; the concrete layer display module is made of concrete or simulated concrete material; and the floor tile display module a and the second floor tile display module b are made of floor tiles or simulated floor tile material.

[0023] Preferably, the heat circulation assembly includes: a circulation tank for containing circulating liquid; a heater for heating the liquid in the circulation tank; and circulation piping connecting the plastic pipe and the oxygen-resistant underfloor heating pipe to the circulation tank.

[0024] In practical use, a circulation pump is installed inside the circulation tank to drive the internal liquid to circulate. The heat circulation component is connected to the plastic pipe of the uniform heat storage layer display module and the oxygen-resistant underfloor heating pipe of the dry-laid underfloor heating module through the circulation pipeline, forming a closed-loop system with the circulation tank and heater: after the heater heats the liquid in the circulation tank, the hot liquid is driven by the circulation pump to flow through the core heating unit (oxygen-resistant underfloor heating pipe) and the heat diffusion unit (plastic pipe) in sequence, completely restoring the real path of heat transfer from the underfloor heating pipe to the heat storage layer when the dry-laid underfloor heating system is working - the oxygen-resistant underfloor heating pipe directly simulates the heat source, and its surface heating effect can be observed; the hot liquid flowing in the transparent plastic pipe dynamically visualizes the radiation and conduction process of heat in the heat storage layer. The two pipes work together to realize the immersive demonstration of the whole process of "heat source generation → heat transfer → heat storage and release", which significantly improves the systematicness and scientific nature of the principle demonstration.

[0025] Preferably, the lifting drive assembly includes: a motor fixed inside the cabinet; a gearbox fixed inside the cabinet, with its input end connected to the output shaft of the motor; a lead screw, arranged vertically, with its upper end rotatably connected to the top of the cabinet and its lower end connected to the output end of the gearbox; the lead screw is threadedly engaged with the internal threaded sleeve of the lifting seat; at least one guide rod, arranged vertically, with its upper and lower ends respectively fixed to the inner top and inner bottom of the cabinet; the guide rod is slidably engaged with a guide structure provided on the lifting seat.

[0026] In practical use, the lifting drive assembly outputs power to the vertically set lead screw through the motor-driven gearbox. The screw and the internal threaded sleeve of the lifting seat convert the rotational motion into linear lifting motion. At the same time, at least one guide rod fixed at both ends to the cabinet forms a sliding pair with the guide structure of the lifting seat. When the lead screw bears the main driving force, the guide rod bears the radial load and suppresses the torsion and offset of the lifting seat. This ensures that the graded lifting shaft and the six display modules (from the concrete layer display module to the floor tile display module b) passing through it rise and fall smoothly along a strictly vertical trajectory, thereby ensuring the centering accuracy and structural stability of each module during the lifting and separation process.

[0027] Compared with the prior art, this utility model provides a platform for demonstrating the structural principle of dry-laid underfloor heating, which has the following beneficial effects:

[0028] This dry-laid underfloor heating structure principle demonstration platform achieves a dual breakthrough in dynamic reverse layering and realistic heat transfer of the dry-laid underfloor heating structure. By replacing static display with mechanical linkage of graded lifting shafts, the six-layer structure from the surface decoration layer to the concrete base layer is precisely separated and raised layer by layer according to the actual inspection logic, intuitively presenting the layered relationship of the hidden project. At the same time, it integrates a dual-pipe heat circulation system, which synchronously pumps heating liquid into the oxygen-permeable underfloor heating pipes and plastic pipes, dynamically simulating the entire process of underfloor heating pipe heating, heat storage layer heat conduction and heat radiation. For the first time, it restores the real physical effect of "heat source generation-transfer-storage" in the demonstration device, completely solving the core defects of traditional demonstration models such as flat structure and static function.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Example:

[0041] Please see Figures 1-7 This utility model provides a technical solution: a display platform for the structural principle of dry-laid underfloor heating, including a cabinet 30;

[0042] Storage box 10 fixed on cabinet 30;

[0043] The underfloor heating display component 20 can be stored in the storage box 10 or raised and unfolded from the storage box 10; the underfloor heating display component 20 includes:

[0044] The graded lifting shaft 210 is composed of at least two lifting shaft sections with successively increasing outer diameters, which are fixedly connected along the axial direction, and the difference in outer diameter between adjacent lifting shaft sections is 1-5mm.

[0045] The display modules are arranged in multiple layers, from bottom to top, including a concrete layer display module 240, a dry-laid underfloor heating module 250, a composite insulation layer display module 260, a heat storage layer display module 270, a floor tile display module a280, and a floor tile display module b290; wherein, the concrete layer display module 240, the dry-laid underfloor heating module 250, the composite insulation layer display module 260, the heat storage layer display module 270, the floor tile display module a280, and the floor tile display module b290 are each provided with through holes that penetrate their thickness;

[0046] The inner diameter of the through hole of each display module is matched with the outer diameter of the corresponding section of the lifting shaft in the graded lifting shaft 210, and the inner diameter of each through hole decreases from bottom to top.

[0047] The outer diameter of the bottom lifting shaft section of the graded lifting shaft 210 is the largest, and the inner diameter of the through hole of the display module that matches it is the largest. The outer diameter of the top lifting shaft section of the graded lifting shaft 210 is the smallest, and the inner diameter of the through hole of the display module that matches it is the smallest.

[0048] The lifting seat 220 is fixedly connected to the bottom end of the stage lifting shaft 210 and is used to drive the stage lifting shaft 210 to rise and fall.

[0049] Glass 230 is fixedly connected to the top end of the staged lifting shaft 210;

[0050] The lifting drive assembly 40 is installed inside the cabinet 30 and connected to the lifting seat 220, and is used to drive the lifting seat 220 and the graded lifting shaft 210 fixed thereto to lift.

[0051] In practical use, when the lifting drive assembly 40 drives the lifting seat 220 and the tiered lifting shaft 210 to rise, the lifting shaft d214 of the tiered lifting shaft 210 first lifts the floor tile display modules a280 and b290, whose apertures are equal to those of the lifting shaft e215. As the lifting height increases, the next level of the second largest outer diameter lifting shaft c213 lifts the heat storage layer display module 270, whose aperture is equal to that of the lifting shaft d214. This process continues until the bottommost largest outer diameter lifting shaft a211 lifts the concrete layer display module 240, whose aperture is equal to that of the lifting shaft b212, thus achieving the display of all layers. The sequential separation and unfolding of modules is achieved through a design that matches the aperture of the tiered lifting shaft 210 with the stacked display modules. Utilizing the characteristic that the outer diameter of the lifting shaft gradually decreases from bottom to top, the upper-layer modules are lifted first during the ascent, and the lower-layer modules are sequentially separated downwards. Ultimately, this achieves a reverse decomposition display that exposes the surface decorative layer to the underground structural layer layer by layer. This not only intuitively simulates the real underfloor heating profile inspection logic, but also replaces a complex transmission mechanism with a precise fit between the shaft shoulder and the aperture. This ensures stable separation of each layer of modules while significantly simplifying the structure, reducing the failure rate, and significantly improving the display efficiency and immersive experience of the dry-laid underfloor heating layering principle.

[0052] Preferably, the graded lifting shaft 210 is composed of five lifting shafts a211, b212, c213, d214 and e215 with successively smaller outer diameters, which are fixedly connected along the axial direction, and the difference in outer diameter between adjacent lifting shaft segments is 2mm.

[0053] In practical use, this tolerance value can ensure that each lifting shaft section (such as lifting shaft b212, lifting shaft c213, etc.) forms a precise sliding clearance fit with the corresponding display module through hole (such as the through hole of concrete layer display module 240 and dry-laid underfloor heating module 250), avoiding jamming or shaking. It can also clearly separate the six-layer stacked modules (from concrete layer display module 240 to floor tile display module b290) within a limited stroke through a small outer diameter difference (2mm), achieving precise control of the height difference of each layer, while reducing the processing accuracy requirements and manufacturing costs.

[0054] Preferably, the concrete layer display module 240, the dry-laid underfloor heating module 250, the composite insulation layer display module 260, the heat storage layer display module 270, the floor tile display module a280, and the floor tile display module b290 are stacked sequentially from bottom to top; the inner diameter of the through hole of the concrete layer display module 240 is equal to the outer diameter of the lifting shaft b212, the inner diameter of the through hole of the dry-laid underfloor heating module 250 and the composite insulation layer display module 260 is equal to the outer diameter of the lifting shaft c213, the inner diameter of the through hole of the heat storage layer display module 270 is equal to the outer diameter of the lifting shaft d214, and the inner diameter of the through hole of the floor tile display module a280 and the floor tile display module b290 is equal to the outer diameter of the lifting shaft e215.

[0055] In practical use, by precisely matching the through holes of the display modules with the corresponding outer diameter of the shaft segments of the graded lifting shaft 210, while ensuring that the reverse inspection logic of prioritizing the separation of the surface decoration layer (floor tile display modules a280 / b290) and exposing it layer by layer downwards to the concrete base layer 240 is strictly followed when lifting from bottom to top, the functional related layers (dry-laid underfloor heating module 250 and composite insulation layer display module 260) are set to have the same hole diameter and are lifted synchronously by the same shaft segment (lifting shaft c213), which reduces the number of shaft segments, simplifies the structure, and maintains the integrity between layers in actual engineering. With the synergistic effect of precision tolerances and guide sliding shaft 222, the horizontal offset of the modules is effectively eliminated, and the precise positioning and stable separation of the six-layer modules are achieved in a limited space.

[0056] Preferably, the lifting seat 220 includes: an internally threaded sleeve 221, which is threadedly engaged with the output end of the lifting drive assembly 40; at least one guide shaft 222, which is fixed between the lifting seat 220 and the glass 230, and is slidably engaged with the guide hole provided on the cabinet 30 or the storage box 10, and the guide shaft 222 sequentially passes through the concrete layer display module 240, the dry-laid underfloor heating module 250, the composite insulation layer display module 260, the heat storage layer display module 270, the floor tile display module a280, and the floor tile display module b290, and is slidably engaged with them.

[0057] In practical use, the lifting seat 220 achieves vertical lifting drive through the threaded engagement of the internal threaded sleeve 221 with the lead screw 430 of the lifting drive assembly 40. At the same time, a rigid support frame is formed by at least one guide shaft 222 that passes through all display modules (from concrete layer display module 240 to floor tile display module b290) – one end of which is fixed to the lifting seat 220 and the other end is fixed to the glass 230. The guide shaft 222 slides with the guide hole on the cabinet 30 or storage box 10 to constrain the horizontal degree of freedom of the lifting seat 220, and simultaneously passes through the through hole of each layer of display module to form a sliding pair. The guide shaft 222 has a keyway structure along the axial direction to prevent the deflection of each display module. When the tiered lifting shaft 210 performs tiered lifting, it works together to suppress the radial offset and torsion of the modules, ensuring that the six-layer modules always remain vertically aligned and stably separated during the lifting process.

[0058] Preferably, the composite insulation layer display module 260 is equipped with a floor heating reflective film 261 and a wire mesh 262; the dry-laid floor heating module 250 is equipped with an oxygen-resistant floor heating pipe 251; the heat storage layer display module 270 is equipped with a plastic pipe 271; the concrete layer display module 240 is made of concrete or simulated concrete material; the floor tile display module a280 and the second floor tile display module b290 are made of floor tiles or simulated floor tile material.

[0059] Preferably, the heat circulation assembly 50 includes: a circulation tank 510 for containing circulating liquid; a heater 520 for heating the liquid in the circulation tank 510; and a circulation pipeline 530 for connecting the plastic pipe 271 and the oxygen-resistant underfloor heating pipe 251 to the circulation tank 510.

[0060] In practical use, a circulation pump is installed inside the circulation tank 510 to drive the internal liquid to circulate. The heat circulation component 50 is simultaneously connected to the plastic pipe 271 of the uniform heat storage layer display module 270 and the oxygen-resistant underfloor heating pipe 251 of the dry-laid underfloor heating module 250 through the circulation pipeline 530, forming a closed-loop system with the circulation tank 510 and the heater 520: after the heater 520 heats the liquid in the circulation tank 510, the hot liquid is driven by the circulation pump to flow sequentially through the core heating unit (oxygen-resistant underfloor heating pipe 251). The system includes a heat diffusion unit (plastic pipe 271), which fully replicates the actual path of heat transfer from the underfloor heating pipe 251 to the heat storage layer 270 during the operation of a dry-laid underfloor heating system. The oxygen-resistant underfloor heating pipe 251 directly simulates the heat source, and its surface heating effect can be observed. The hot liquid flowing inside the transparent plastic pipe 271 dynamically visualizes the radiation and conduction process of heat in the heat storage layer. The two pipes work together to achieve an immersive demonstration of the entire process of "heat source generation → heat transfer → heat storage and release", which significantly improves the systematicness and scientific nature of the principle demonstration.

[0061] Preferably, the lifting drive assembly 40 includes: a motor 410 fixed inside the cabinet 30; a gearbox 420 fixed inside the cabinet 30, with its input end connected to the output shaft of the motor 410; a lead screw 430, arranged vertically, with its upper end rotatably connected to the top inside the cabinet 30 and its lower end connected to the output end of the gearbox 420; the lead screw 430 is threadedly engaged with the internal threaded sleeve 221 of the lifting seat 220; at least one guide rod 440, arranged vertically, with its upper and lower ends fixed to the inner top and inner bottom of the cabinet 30, respectively; the guide rod 440 is slidably engaged with a guide structure provided on the lifting seat 220.

[0062] In practical use, the lifting drive assembly 40 drives the gearbox 420 via the motor 410 to output power to the vertically set lead screw 430. The rotational motion is converted into linear lifting motion by the threaded engagement between the lead screw 430 and the internal threaded sleeve 221 of the lifting seat 220. At the same time, at least one guide rod 440, which is fixed at both ends to the cabinet 30, forms a sliding pair with the guide structure of the lifting seat 220. When the lead screw 430 bears the main driving force, the guide rod 440 bears the radial load and suppresses the torsion and offset of the lifting seat 220. This ensures that the graded lifting shaft 210 and the six-layer display module concrete layer display module 240 to the floor tile display module b290 passing through it rise and fall smoothly along a strictly vertical trajectory, thereby ensuring the centering accuracy and structural stability of each layer module during the lifting and separation process.

[0063] Working principle: When displaying each module in layers, the motor 410 drives the lead screw 430 to push the lifting seat 220 vertically upward, and the graded lifting shaft 210 fixed on it is raised synchronously. This shaft consists of five shaft segments (lifting shafts a211 to e215) with an outer diameter that decreases by 2mm from bottom to top. Through the precise matching of the shaft shoulder with the hole diameter of each layer of display module (e.g., the smallest shaft segment e215 matches the hole diameter of the floor tile module a280 / b290), the upper layer module is lifted first during the lifting process, and the lower layer modules are sequentially triggered to separate. Finally, the six-layer structure is unfolded in reverse from the surface decoration layer to the concrete base layer. The guide slide shaft 222 that runs through all modules works in conjunction with the guide hole of the cabinet 30 to ensure zero offset and zero twisting of the modules during the lifting process, thereby achieving a three-dimensional display effect.

[0064] Simultaneously, the heater 520 heats the liquid in the circulation tank 510, and the hot liquid is driven by the circulation pump to flow sequentially through the oxygen-resistant floor heating pipe 251 of the dry-laid floor heating module 250 and the plastic pipe 271 of the heat equalization layer module 270, completely restoring the heat transfer path—the surface temperature rise of the oxygen-resistant floor heating pipe 251 simulates the real heat source, and the dynamic visualization of the heat diffusion effect in the heat storage layer by the hot liquid flowing in the transparent plastic pipe 271, thus presenting the physical process of "heat source generation → pipe heat transfer → heat storage and release" in the process of structural dissection.
