Description

Technical Field

[0001] This utility model belongs to the field of spring bed core display technology, specifically relating to a spring performance display prop. Background Technology

[0002] In the scenario of demonstrating mattress spring performance, existing methods have significant limitations and cannot meet the needs for intuitive and accurate demonstrations. Specific problems are as follows: 1. Existing test logic for demonstration props is simplistic and highly subjective. Mainstream solutions often employ the "drop ball test," which evaluates spring performance by comparing the number of spring rebounds and the height the ball rises. However, the core variable of this method (drop ball height) relies on manual control, making it susceptible to the operator's subjective judgment. This results in poor test results, low repeatability, and a lack of standardized criteria, leading to consumer distrust of the demonstration effects. Furthermore, the drop ball test only reflects the spring's rebound characteristics under a single impact scenario, failing to cover the "continuous load" working state of a mattress in actual use. Therefore, the results lack universality and cannot truly reflect the long-term support performance of the springs.

[0003] 2. Existing solutions have poor adaptability to demonstrating pocket springs. As a mainstream mattress core structure, pocket springs are actually constrained by the fabric pockets during operation. However, existing tests require removing the pockets and taking out the springs for individual testing, which is cumbersome and damages the integrity of the product during testing. Furthermore, once the springs are removed from the constraints of the fabric pockets, the test conditions differ greatly from the actual usage conditions, failing to intuitively reflect the true performance of pocket springs in a mattress, resulting in a disconnect between test results and actual user experience.

[0004] 3. Existing display props can only demonstrate the performance of one type of spring, and most of them lack a visual display structure, allowing only the deformation of the spring to be observed with the naked eye, making it difficult to accurately present the spring's performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spring performance demonstration prop. By controlling the displacement of the limiting plate through a limiting block, two sets of spring cores are compressed simultaneously from the top and bottom sides, ensuring that the compression amount of the two sets of spring cores is exactly the same, thereby achieving an intuitive and visual comparison of spring performance.

[0006] This utility model provides the following technical solution: A spring performance demonstration prop includes a frame structure consisting of two main plates and four side plates, and a spring bed core placed inside the frame structure. The spring bed core includes a partition plate, two sets of spring cores and a limiting plate. One end of each set of spring cores is respectively set on both sides of the partition plate, and the other end of each set of spring cores is set with a limiting plate. Each motherboard and each side plate is provided with a limiting groove. A limiting block is provided in the limiting groove to limit the displacement of the limiting plate. The limiting block controls the displacement of the limiting plate to compress the two sets of spring cores, so that the displacement of the two sets of spring cores can be intuitively displayed after the two sets of spring cores are balanced.

[0007] The system comprises a frame structure with a main board and side plates, within which a spring bed core containing two sets of spring cores is installed. Limiting blocks control the displacement of a limiting plate to simultaneously compress the two sets of spring cores from both top and bottom, ensuring that the compression amounts of the two sets of spring cores are identical. This allows for a direct and visual comparison of the displacement of the two sets of spring cores after they reach equilibrium, providing a clear comparison of spring performance. This structure can simultaneously compare the performance of two types of springs, solving the problem that existing display props can only showcase the performance of one type of spring and are not intuitive.

[0008] In a preferred embodiment, a limiting groove is provided in the middle of the upper and lower sides of each motherboard and in the middle of each side plate. The limiting groove is 3 / 4 cylindrical.

[0009] The limiting grooves provide precise installation and rotation space for the limiting blocks. Simultaneously, four limiting grooves are provided on both the upper and lower sides of the frame structure, ensuring more even force distribution on the limiting plates. This, in turn, ensures uniform pressure on the entire spring bed core, guaranteeing the reliability of the performance demonstration results.

[0010] In a preferred embodiment, the limiting block is a 3 / 4 cylindrical block, and the limiting block is installed in the limiting groove via a limiting post.

[0011] The limiting block is a 3 / 4 cylindrical block installed in the limiting groove via a limiting post. The limiting block and the 3 / 4 cylindrical limiting groove are highly compatible, enabling stable rotation. This structural design allows the limiting block to precisely adjust the degree of constraint on the limiting plate through rotation, thereby accurately controlling the compression of the spring core.

[0012] In a preferred embodiment, springs are provided at both ends of the limiting post to facilitate the installation of the limiting block.

[0013] Springs are installed at both ends of the limiting post. Utilizing the elastic deformation characteristics of the springs, the limiting block can be easily inserted into the limiting groove during installation by compressing the springs at both ends. After installation, the springs return to their original position, firmly locking the limiting block in the limiting groove, eliminating the need for complex fixing structures. This design simplifies the installation process of the limiting block, improves assembly efficiency, and ensures the stability of the limiting block during use.

[0014] In a preferred embodiment, the limiting post is located at the center of the limiting block.

[0015] The limiting post is located at the center of the limiting block, so that the limiting block makes circular motion around the center as the axis during rotation, making the rotation of the limiting block more stable and improving the accuracy of displacement control. In this way, the compression of the spring core can be precisely controlled through the limiting block.

[0016] In a preferred embodiment, the motherboard and the side panel are connected by a mortise and tenon structure.

[0017] The use of mortise and tenon joints allows for initial fixation of the frame structure without additional fasteners, resulting in a tight and stable connection. This connection method simplifies the initial assembly process, and the overall load-bearing capacity of the frame is strong, capable of withstanding the reaction force generated when springs are compressed.

[0018] In a preferred embodiment, the connection between the motherboard and the side panel is secured with fasteners to enhance the stability of the frame structure.

[0019] Fasteners can further enhance the stability and robustness of the frame structure, prevent deformation or loosening of the frame structure during long-term use, and extend the service life of the props.

[0020] In a preferred embodiment, each motherboard has a viewing window in the middle.

[0021] The visual window allows users to directly observe the compression state and displacement changes of the spring core inside the frame. They can intuitively understand the spring performance without disassembling the prop, which enhances the prop's display and solves the problem of traditional props requiring unpacking for testing and observation.

[0022] In a preferred embodiment, the viewing window is covered by a transparent panel.

[0023] The viewing window is covered with a transparent panel, which can block external dust and debris from entering the frame structure and protect the spring core from contamination or damage.

[0024] In one preferred embodiment, the transparent plate is marked with a scale based on the initial position of the partition plate to visually display the displacement of the two sets of spring bed cores.

[0025] The transparent plate is marked with graduations, allowing direct quantification of the displacement of the two sets of spring cores. Users can quickly determine the spring constant and support by comparing the graduations, making the performance comparison results more intuitive and accurate.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: The system comprises a frame structure with a main board and side plates, within which a spring bed core containing two sets of spring cores is installed. Limiting blocks restrict the displacement of a limiting plate, allowing for simultaneous compression of the two sets of spring cores from both top and bottom, ensuring identical compression amounts. This allows for a direct and visual comparison of the displacement of the two sets of spring cores after they reach equilibrium, providing a clear comparison of spring performance. This structure can simultaneously compare the performance of two types of springs, solving the problem that existing display props can only showcase the performance of one type of spring and are not intuitive.

[0027] The frame structure has four limiting slots on both the top and bottom sides. The limiting blocks are installed in the limiting slots through the limiting posts, which makes the rotation of the limiting blocks more stable and the force on the limiting plate more uniform. This makes the spring bed core uniformly compressed as a whole, ensuring the reliability of the performance demonstration results.

[0028] The view window allows users to directly observe the compression state and displacement changes of the spring core inside the frame, while the scale markings make the performance comparison results more intuitive and accurate. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1: like Figure 1 and Figure 2 As shown, the spring performance demonstration prop includes a frame structure consisting of two main boards 1 and four side boards 2, as well as a spring bed core 3 placed inside the frame structure.

[0033] The main board 1 and the side panel 2 are connected by mortise and tenon joints to form a frame structure. At the same time, the connection is fixed with fasteners 7 to enhance the stability of the frame structure.

[0034] This connection method simplifies the initial assembly process of the prop, and the resulting frame structure has a strong overall load-bearing capacity, capable of withstanding the reaction force generated when the spring is compressed. Fixture 7 further enhances the stability and robustness of the frame structure, preventing deformation or loosening during long-term use and extending the prop's lifespan.

[0035] Specifically, the structure of the spring core 3 is shown in Figure 3, including a partition plate 302, two sets of spring cores 301, and a limiting plate 303. The limiting plate 303, spring core 301, partition plate 302, spring core 301, and limiting plate 303 are arranged sequentially from top to bottom. The partition plate 302 separates the two sets of spring cores 301, allowing both sets to be simultaneously housed within the frame structure. This facilitates simultaneous performance testing of both sets of spring cores 301 and provides a clear visual representation of the test results. Furthermore, this structural design eliminates the need to disassemble the spring core during testing, thus providing a direct reflection of the actual performance of the pocketed springs in the mattress.

[0036] like Figure 2 As shown, a limiting groove 4 is provided in the middle of the upper and lower sides of each main board 1 and in the middle of each side plate 2, that is, four limiting grooves 4 are provided on the upper and lower sides of the frame structure. A limiting block 5 is provided within the limiting groove 4 to limit the displacement of the limiting plate 303. The limiting block 5 is composed of multiple stacked rotatable blocks. Figure 1When the third rotatable block switches from the avoidance state to the limit state, the rotatable block protrudes from the surface of the main board 1, thereby limiting the displacement of the limit plate 303.

[0037] During the specific test, the limiting plates 303 are first compressed from both sides by external force. Then, the limiting blocks 5 are adjusted in time to ensure that the displacement of the upper and lower limiting plates 303 is the same, thereby ensuring that the two sets of spring cores 301 are compressed synchronously and by the same amount. After the two sets of spring cores 301 are balanced, the displacement of the two sets of spring cores 301 can be intuitively displayed by observing the position change of the partition plate 302, so that users can intuitively understand the performance of the two sets of spring cores 301.

[0038] Specifically: According to Hooke's Law F=k×Δx, the reaction force F generated by the spring is proportional to the compression Δx; where k is the spring constant, representing the stiffness of the spring, and the larger the value of k, the stronger the spring's support.

[0039] Two sets of spring cores 301 are compressed simultaneously from both the top and bottom, and the limiting block 5 controls the two sets of spring cores 301 to have the same amount of compression. The partition plate 302 acts as a force balance indicator. Before compression, the partition plate 302 is located in the center position. After compression, if the k values ​​of the two sets of spring cores 301 are the same, the reaction forces they produce are also the same, and the position of the partition plate 302 remains unchanged. If the k values ​​of the two sets of spring cores 301 are different, the spring with the larger k value will produce a larger reaction force, causing the partition plate to shift towards the spring with the smaller k value, thus visually demonstrating the performance of the two sets of spring cores 301.

[0040] The spring performance display prop provided by this utility model can compare the performance of two springs at the same time, solving the problem that existing display props can only display the performance of one type of spring and the display is not intuitive.

[0041] like Figure 2 and Figure 4 As shown, to more intuitively demonstrate the performance of the two sets of spring cores 301, a viewing window 101 is provided in the middle of each main board 1. The setting of the viewing window 101 allows users to directly observe the compression state and displacement changes of the spring cores 301 inside the frame, and to intuitively understand the spring performance without disassembling the prop, which enhances the display of the prop and solves the problem of the inconvenience of traditional props requiring unpacking for testing and observation.

[0042] Meanwhile, each motherboard 1 has vertical limiting protrusions 102 on both the left and right sides to limit the horizontal displacement of the partition plate 302 and / or the limiting plate 303 from the viewing window 101.

[0043] Furthermore, the viewing window 101 is covered by a transparent plate, which is marked with graduations based on the initial position of the partition plate 302. The transparent plate design prevents external dust and debris from entering the frame structure, protecting the spring core 301 from contamination or damage. Simultaneously, the graduations directly quantify the displacement of the two sets of spring cores 301. Users can quickly determine the spring constant (spring K-value) and support performance by comparing the graduations, making the performance comparison results more intuitive and accurate.

[0044] Furthermore, such as Figure 4 and Figure 5 As shown, the limiting groove 4 is a 3 / 4 cylinder, the limiting block 5 is a 3 / 4 cylinder, and the limiting block 5 is installed in the limiting groove 4 through the limiting post 6.

[0045] The limiting groove 4 provides precise installation and rotation space for the limiting block 5. The limiting block 5 is a 3 / 4 cylindrical block installed in the limiting groove 4 via the limiting post 6. The limiting block 5 and the 3 / 4 cylindrical limiting groove 4 are highly compatible, enabling stable rotation. This structural design allows the limiting block 5 to precisely adjust the degree of constraint on the limiting plate 303 through rotation, thereby accurately controlling the compression of the spring core 301.

[0046] Specifically, the limiting post 6 is located at the center of the limiting block 5, so that the limiting block 5 makes circular motion around the center as the axis during rotation, making the rotation of the limiting block 5 more stable, thereby accurately controlling the compression of the spring core 301.

[0047] Specifically, such as Figure 2 and Figure 4 As shown, one end (upper or lower end) of the limiting groove 4 is open and exposed to the motherboard 1 and the side plate 2. That is, the upper end of the limiting groove 4 located on the upper side of the frame structure is open and exposed to the motherboard 1 and the side plate 2, and the lower end of the limiting groove 4 located on the lower side of the frame structure is open and exposed to the motherboard 1 and the side plate 2. A cover plate is provided on the outer side of the open end of the limiting groove 4, and an insertion hole for installing the limiting post 6 is provided on the cover plate. The other end of the limiting groove 4 is located inside the motherboard 1 and the side plate 2, and another insertion hole for installing the limiting post 6 is provided in the limiting groove 4 at this end.

[0048] During installation, the limiting post 6 passes through the limiting block 5, and then one end of the limiting post 6 is inserted into the insertion hole located in the limiting groove 4. The insertion hole on the cover plate is inserted into the other end of the limiting post 6, and then the cover plate is tightened to complete the installation of the limiting block 5 and the limiting post 6.

[0049] Furthermore, since the initial height of each spring core 301 is different, when different spring bed cores 3 are placed in the frame structure, the initial position of the upper and lower limit plates 303 and the distance between the upper and lower end faces of the main board 1 are quite different. In order to facilitate the demonstration of the performance of different spring cores 301, the limit groove 4 is designed with a higher height. When testing different spring bed cores 3, the number of limit blocks can be adjusted according to the actual height of the spring bed core 3.

[0050] Furthermore, if the initial height of the spring core 301 is high, when the spring bed core 3 is placed inside the frame structure, the initial position of the upper limiting plate 303 is higher, and the initial position of the lower limiting plate 303 is lower. In this case, the limiting plate 303 will block the limiting block 5. During testing, it is necessary to press down the two limiting plates 303 to expose the limiting block 5, and then adjust the limiting block 5. For ease of testing, such as Figure 2 As shown, a limiting push plate 8 and a push plate spring 9 are set below the limiting block 5 so that the limiting block 5 is located above the limiting groove 4. During the test, the limiting block 5 can be exposed without pressing the limiting plates 303 on both sides too much, thus completing the test.

[0051] Example 2: The difference between this embodiment and Embodiment 1 is that: like Figure 6 and Figure 7 As shown, both ends of all the limiting slots 4 on the motherboard 1 and side panel 2 are not exposed, and both ends of the limiting slots 4 are provided with insertion holes for mounting limiting posts 6. At this time, the two ends of the limiting posts 6 can extend and retract, and the structure of the limiting posts 6 is as follows. Figure 8 and Figure 9 As shown, the specific structure is as follows: The limiting post 6 includes an outer sleeve 601 and two inner sleeves 602. The two inner sleeves 602 are nested at both ends of the outer sleeve 601, and the inner sleeves 602 can slide axially along the outer sleeve 601. Spring support seats 604 are provided inside both ends of the outer sleeve 601. A spring 603 is installed in the space formed between the spring support seat 604 and the top of the corresponding inner sleeve 602. A limiting structure 605 is provided at the bottom of the inner sleeve 602 to control the axial sliding distance of the inner sleeve 602. When the top of the inner sleeve 602 is subjected to force, the spring 603 is compressed, and the inner sleeve 602 retracts into the outer sleeve 601; after the external force is removed, the spring 603 returns to its original position, thereby causing the inner sleeve 602 to return to its original position.

[0052] During installation, the limiting post 6 passes through the limiting block 5. Then, utilizing the elastic deformation characteristic of the spring 603, the tops of the inner sleeves 602 at both ends of the limiting post 6 are pressed, causing them to retract into the outer sleeve 601. The limiting block 5 is then placed into the limiting groove 4, and the inner sleeves 602 at both ends of the limiting post 6 are aligned and inserted into the insertion holes of the limiting groove 4. After installation, the spring 603 returns to its original position, causing the inner sleeves 602 to return to their original position, thus locking the inner sleeves 602 into the insertion holes of the limiting groove 4, ensuring that the limiting block 5 is securely locked within the limiting groove 4. This design simplifies the installation process of the limiting block 5, improves assembly efficiency, and ensures the stability of the limiting block 5 during use.

[0053] The remaining structure and effects of this embodiment are the same as those of Embodiment 1, and will not be described again.

[0054] In summary, this utility model restricts the displacement of the limiting plate 303 by limiting block 5, thereby achieving synchronous compression of two sets of spring cores 301 from the top and bottom sides. During compression, the compression amount of the two sets of spring cores 301 is exactly the same. Thus, after the two sets of spring cores 301 are balanced, the displacement of the two sets of spring cores 301 can be intuitively displayed, realizing an intuitive and visual comparison of the performance of the two springs. This solves the problem that existing display props can only display one type of spring performance and the display is not intuitive.

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
