In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0031] like Figure 1 As shown, a measuring device for architectural design according to this application includes several main components. The measuring tape box 1 is the core container structure of the measuring device. It has sufficient volume to accommodate one of the key internal components—the measuring tape 11. Its outer shell is made of high-strength, weather-resistant materials to avoid the influence of external environmental factors such as dust and humidity on the performance of the internal mechanism. At the same time, it also creates a relatively closed and stable internal working area to ensure the accuracy of the measurement work.

[0032] Further reference Figure 3 The brake disc 2 is located next to the spool 12 around which the aforementioned measuring tape 11 is wound. Specifically, this design is not a simple adjacent placement, but rather connects the two through a specialized structure, allowing the brake disc 2 to sense the operational status of the measuring tape 11 to a certain extent. The brake disc 2 possesses a unique self-adjusting function, dynamically adjusting the pressure against the measuring tape surface based on the actual stress generated during tape retraction and extension. In its selection, a high-friction coefficient material can be used to manufacture the brake disc 2, ensuring greater contact friction when braking is required. The flexible connector 22 establishes a stable connection channel between the brake disc 2 and the measuring tape housing 1, preventing structural breakage or failure in extreme cases of excessive external force, thus protecting critical internal components.

[0033] Further reference Figure 2 The handle 3 is mounted on the aforementioned measuring tape housing 1. The handle 3 can rotate around a specific axis to allow the user to manually adjust the extension and retraction inlet's movement according to the specific measurement task requirements.

[0034] A small component called a measuring tape lock 4 is provided at one end of the measuring tape strap 11. The function of this accessory is to allow the operator to stably fasten the unfolded tool at a suitable position at the end of the required measurement distance, so as to achieve the requirement of fixed-point anchoring. At the same time, this configuration is also conducive to the use with the measuring tape casing, that is, it does not interfere with the smooth performance of the measuring tape in and out of the operation process.

[0035] In one embodiment, see specific reference. Figure 3 and Figure 4The design of the self-adjusting structure 21 of the brake disc 2 in the architectural design measuring device of this application is particularly crucial. This self-adjusting structure 21 includes a set of symmetrically arranged telescopic rods 23 and high-strength springs 24. These components are used to automatically adjust the position of the brake disc 2 according to the thickness of the measuring tape 11. This design ensures that appropriate contact pressure and stable friction are maintained regardless of changes in the thickness of the measuring tape 11 under different usage conditions. Specifically, two telescopic rods 23 are located at both ends of the brake disc 2 and are arranged symmetrically. Their length can flexibly contract and extend according to changes in external force or internal component conditions. A set of high-strength springs 24 works in conjunction with each telescopic rod 23. These high-strength springs 24 are connected to the internal structure of the brake disc 2, providing the necessary restoring force while ensuring a certain degree of elasticity to push the brake disc 2 to adjust the distance according to the degree of retraction of the measuring tape 11.

[0036] From a technical implementation perspective, when the measuring tape 11 extends to different degrees, its material properties cause corresponding bending deformation, leading to changes in local thickness. At this time, the telescopic rod 23 moves accordingly within a preset range, thereby generating a corresponding force by compressing or stretching the high-strength spring 24, ultimately achieving adaptive position adjustment. For example, during the process of the measuring tape being fully retracted or partially extended, the telescopic rod 23 and the high-strength spring 24 system dynamically balance internal and external pressures, ensuring that the brake disc 2 remains firmly in contact and appropriately controls the movement of the measuring tape 11.

[0037] In one embodiment, see specific reference. Figure 3 In this application, a telescopic rod 23 and a flexible connector 22 for a measuring device used in architectural design are provided with a bearing shaft 25, which can fix the brake disc 2 as a whole inside the measuring tape housing 1 through the flexible connector 22. This design ensures that the brake disc 2 can be flexibly installed and effectively transmit force while maintaining the stability of its function.

[0038] In this specific embodiment, the measuring tape housing 1 serves as the main frame of the entire device, providing safety protection and support for internal components such as the brake disc 2. The flexible connector 22 plays a crucial role here, possessing not only flexibility, allowing the brake disc 2 to move and bend to a certain extent, but also transmitting external operating forces to the brake disc 2. To ensure good cooperation and stable connection between these components, the telescopic rod 23 and the flexible connector 22 together form a robust support system, with one end of the telescopic rod 23 securely connected to the brake disc 2, and the other end connected to the flexible connector 22 via the load-bearing shaft 25. This combination further enhances the system's durability and responsiveness under different operating conditions.

[0039] In terms of technical implementation, the flexible connector 22 is fixed in a specific area within the measuring tape housing 1 and connected to the telescopic rod 23 via the bearing shaft 25. This installation position ensures that the brake disc 2 maintains sufficient flexibility during operation while preventing irreversible damage from external impacts. For example, the flexible connector 22 is made of a highly elastic material and designed in a multi-segment form to better adapt to various shape changes. When the applied force exceeds a predetermined range, it can absorb excess energy through elastic deformation, thereby making the entire device safer and more reliable.

[0040] In one embodiment, the flexible connector 22 of a measuring device for architectural design according to this application is made of a variable stiffness material. This flexible connector 22 connects the brake disc 2 and the measuring tape housing 1, providing necessary support. Under normal operating conditions, this variable stiffness material maintains appropriate hardness, supporting the structural stability between the brake disc 2 and the measuring tape housing 1. When subjected to impact loads, such as sudden operational errors or external collision forces acting on the brake disc 2, the variable stiffness material can instantly adjust its stiffness to a lower level. At this time, the flexible connector 22 disperses energy through buffering, preventing excessive stress from being transferred to other critical components, thereby effectively reducing the risk of damage to internal components. This characteristic is of great significance for improving the overall durability and reliability of the measuring device.

[0041] Specifically, the flexible connector 22 can be made of a polymer composite material with specific chemical properties, which can undergo corresponding changes in mechanical properties when factors such as temperature and pressure change. Specifically, at the joint between the flexible connector 22 and the measuring tape box 1, a suitable embedded or snap-fit ​​fixing structure is designed to ensure a stable connection without affecting the material's performance. For example, one end of the connector is tightly embedded in the space reserved inside the measuring tape box 1, and the other end is fixed to the bearing shaft 25 using a special adhesive method, thus forming an integrated system that can both stably support the brake disc 2 and absorb external impacts.

[0042] In one embodiment, continue to refer to Figure 3 The handle 3 of the measuring device for architectural design in this application is designed with multiple sets of recesses 31 on its outer side, arranged in a circular pattern. These recesses 31 provide the operator with a better grip when holding the handle 3, effectively improving the stability and comfort of operation. Since the outer surface of the handle 3 is usually in frequent contact with the operator's hand, the reasonable design can reduce operational errors caused by slippage or other reasons.

[0043] The recesses 31 on the handle 3 respond to the need for human-computer interaction interface optimization in engineering practice. Specifically, the arrangement of multiple recesses 31 is precisely calculated to ensure that their position and shape conform to the curvature of human fingers, making the handle 3 both visually appealing and practical. This design not only enhances the controllability of operation but also reduces the likelihood of wrist fatigue during prolonged use. The material selection for the handle 3 also takes into account durability and tactile feel, typically using materials with good elasticity and friction properties, such as rubber.

[0044] For example, in one embodiment, the handle 3 is fixedly mounted on the outside of the tape measure housing 1 and connected via a rotating pivot, ensuring that the operator can directly drive the roller 12 to rotate and complete the winding action of the tape measure 11. The presence of multiple sets of recesses 31 does not affect the basic mechanical structure of the handle 3; on the contrary, its shape characteristics are cleverly integrated into the overall device, ensuring the aesthetics and functional compatibility of the handle 3. All recesses 31 are directly integrally molded, reducing subsequent assembly steps and increasing the product's robustness and consistency.

[0045] In one embodiment, a double sealing ring 13 is provided between the measuring tape housing 1 and the measuring tape 11 of the measuring device for architectural design according to this application. The double sealing ring 13 is installed in the contact area between the measuring tape housing 1 and the measuring tape 11 to ensure that the device has excellent dustproof and waterproof performance. This design not only improves the durability of the product, but also indirectly supports the smooth retraction of the measuring tape 11 after use. Even when operating in harsh environments, the double sealing ring 13 can prevent dust and moisture from entering the internal mechanism, avoiding any impact on measurement accuracy and maintaining the good operating condition of the measuring tape 11.

[0046] The sealing ring consists of two layers of different materials. The inner sealing ring is made of highly elastic rubber, providing excellent sealing and resilience. The outer sealing ring is made of wear-resistant and age-resistant polyurethane. The two sealing rings fit together tightly, forming a double barrier. The double sealing ring 13 is directly fixed to the inner edge of the tape measure housing 1 and fits snugly against the tape measure strap 11, ensuring no noticeable gaps in any position. It is connected and fixed to the housing using a reasonable mechanical snap-fit ​​mechanism, ensuring reliability for long-term use. For example, when the tape measure is being retracted or stationary, this unique double sealing ring 13 maintains a good fit without affecting its normal function, allowing users to obtain accurate measurement results under various working conditions and ensuring a long product lifespan.

[0047] In one embodiment, such as Figure 2As shown, the measuring tape housing 1 of a measuring device for architectural design according to this application has a set of guide rails 14 on its inner side. These rails are used to assist the measuring tape 11 in maintaining the correct path during rewinding. This structure effectively prevents the measuring tape from slipping or getting stuck during the rewinding process, especially in the case of rapid rewinding, ensuring accurate guidance of the measuring tape and thus avoiding tangling or damage to internal parts. In addition, the measuring tape housing 1 not only provides an enclosed space to protect the internal components from the influence of the external environment, but also provides a stable and safe operating environment for the measuring tape 11.

[0048] To ensure good guiding effect, guide rails 14 are installed on the inner wall of the measuring tape box 1. Specifically, the rails extend longitudinally along the inner wall of the box to accommodate the rewinding path of the measuring tape strip 11. The rails are made of high-strength material and are tightly connected to the measuring tape box 1. The spacing between each rail is appropriate and evenly distributed to ensure that the measuring tape strip 11 can pass smoothly while maintaining sufficient friction to support the correct alignment of the measuring tape strip 11.

[0049] For example, when the user extends the measuring tape 11 by operating the handle 3 and then pulls it back, the guide rail 14 located inside the measuring tape box 1 will guide the measuring tape 11 to retract smoothly along the set trajectory. With this design, whether manually retracted or automatically reset by the internal spring 24 system, the measuring tape 11 can always spring back along a fixed route without deviating from the predetermined track.

[0050] In one embodiment, the measuring tape lock 4 of the architectural design measuring device of this application is located at the front end of the measuring tape 11 to ensure that the measuring instrument can be safely and securely attached to a fixed point for accurate measurement. The measuring tape lock 4 incorporates a memory metal component 41 with special physical properties, allowing it to automatically return to its initial shape after undergoing significant deformation, thus preparing it for future use. The memory metal component 41 is installed inside the measuring tape lock 4 and tightly embedded in the structure. The measuring tape lock 4 is designed to both firmly press the contact surface when locked to prevent loosening and potential accidental rebound risks, and to ensure a simple and smooth unlocking process for quick operation by the operator.

[0051] When the measuring tape latch 4 is fixed at a certain point, the shape memory metal part 41 ensures that the latch will not shift or loosen due to external force by tightly pressing against the contact surface, thereby effectively reducing the risk of rebound. For example, in the process of selecting and assembling building materials, the measuring device can be firmly fixed to the front end of an object surface, such as a wall, beam, or column, through the measuring tape latch 4 for stable measurement without the need for manual holding.

[0052] For example, shape-memory metal can be shaped and embedded into the tape measure lock 4, allowing it to quickly spring back after deformation under stress. A specific design ensures the metal plate maintains good interaction with its surroundings, enhancing both security and convenience. Simultaneously, the tight fit between the shape-memory metal and the tape measure lock 4's outer shell ensures consistency, maintaining stable rebound characteristics and robustness even under stress after repeated use.

[0053] In one embodiment, a protective frame 15 is added to the edge of the measuring tape 11 of a measuring device for architectural design, effectively preventing damage caused by friction and scratching with external objects during intense pull-back, ensuring that the measuring tape 11 itself remains intact and undamaged for a long time. This design not only extends the service life of the measuring device but also improves the stability of its accuracy performance. Specifically, a protective frame 15 is added along the entire length of the upper edge of the measuring tape 11, completely covering the originally vulnerable parts. By using robust and wear-resistant materials, the frame not only has high structural strength but also adapts to the needs of different usage environments. To better integrate into the overall structure, the joint between this frame and the existing structure is carefully designed to avoid interference with other functional components.

[0054] To achieve the aforementioned technical features, in terms of manufacturing process, the measuring tape 11 is first cut and shaped, and then the protective frame 15 is firmly bonded to the outer edge of the measuring tape 11 by heat fusion or adhesive, so that the two are tightly integrated into one, forming a double protective barrier. This treatment can not only enhance the rigidity of the measuring tape 11 itself, but also reduce the risk of damage caused by external impact, thereby ensuring the smooth progress of measurement work.

[0055] In one embodiment, the measuring tape 11 of a measuring device for architectural design according to this application is constructed with a multi-layered composite material and covered with a special textured coating, thereby significantly increasing its durability and anti-adhesion properties. The structure of the measuring tape 11 not only provides excellent physical properties such as abrasion resistance and corrosion resistance, but also prevents stains and other materials from adhering to its surface through the special textured coating. Furthermore, an elastic film is attached to the back of the measuring tape 11 as an auxiliary braking surface. This film plays a crucial role just before the measuring tape 11 is fully retracted, helping to achieve a smooth transition to a stop and avoiding the mechanical impact caused by the sudden interruption of a conventional measuring tape 11.

[0056] Specifically, the aforementioned elastic film possesses sufficient flexibility to accommodate the bending motion of the measuring tape 11 during winding. As the measuring tape 11 approaches its endpoint inside the housing, the appropriate resistance provided by the film ensures the safety and reliability of the entire retraction process. This unique design, combining a high-friction surface with appropriate elastic recovery, effectively mitigates stress concentration issues caused by sudden stops of the measuring tape 11, even in environments with frequent use.

[0057] For example, a suitable multi-layered composite material can be selected as the main body, and a special coating with a specific micro-geometry can be uniformly sprayed or dipped onto the exterior. Then, a film of suitable thickness and elasticity can be prepared and firmly bonded to the back of the measuring tape 11 near the end of the roller 12. In this way, the original ease of operation is not affected, and it can also play an auxiliary braking function when necessary.

[0058] In actual operation, when this device is in use, the measuring tape 11 can be smoothly pulled out from the measuring tape box 1 by rotating the handle 3. The operator can fix the measuring tape lock 4 at the end of the measuring tape 11 to a fixed point to be measured, ensuring the accuracy and stability of the measurement process. During the retraction and extension of the measuring tape 11, the brake disc 2 can adjust the unfolding speed of the measuring tape 11 according to the external pressure, avoiding damage caused by retraction too quickly. The brake disc 2 is in close contact with the measuring tape 11 through a high-friction coefficient material, and the self-adjusting structure 21 ensures effective contact at all times, preventing damage to the core components even under excessive force. The flexible connector 22 allows the brake disc 2 to have a certain range of motion, further protecting the safety of the device. The overall enclosed design ensures effective isolation of the measuring tape box 1 from the external environment, maintaining the stability and accuracy of the internal structure. Finally, the cooperative design between the measuring tape lock 4 and the measuring tape box 1 allows the measuring tape 11 to be smoothly extended and retracted, completing the entire measurement process.

[0059] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
