Description

Technical Field

[0001] This utility model relates to the field of building decoration tools, specifically a tile leveling power auxiliary mechanism and a tile leveling kit using this tile leveling power auxiliary mechanism. Background Technology

[0002] When tiling during home renovation, the flatness of adjacent tiles is crucial. To meet these requirements, various devices have been developed. Chinese patent document CN118911388A, published on November 8, 2024, discloses a "tile leveling device," comprising: a first component configured to be placed between adjacent tiles; the first component includes a base and a support extending vertically upward from the base, wherein the lower part of the support is a sheet-like portion and the upper part is a rod-like portion; the connection between the support and the base is a tearable portion; a second component configured to fix the first component between the tiles; the second component includes a cylindrical channel for receiving the rod-like portion; a third component connected to the bottom of the second component, with at least a portion of the third component protruding beyond the second component; the third component is configured such that when the second component moves towards the tile, the third component first contacts the tile to fix it. Such existing devices also have some shortcomings in actual use: First, the second component needs to be rotated manually, which is not very efficient; second, when the second component can no longer be rotated to the lowest position, it is the flatness positioning position. However, different operators have different torque, or even different torque of the same operator, which may cause the rotation tightness of the second component at the lowest position to be inconsistent. That is, the flatness positioning position depends on personal feel and cannot be precise and consistent, resulting in uneven height on the entire tile laying surface, which affects the laying quality. Summary of the Invention

Detailed Implementation

[0032] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] Example 1 details a power-assisted mechanism specifically designed for tile leveling operations. For example... Figure 1 and Figure 2As shown, the mechanism mainly consists of three core components: upper transmission block 20, lower transmission block 40, and connecting sleeve 70. They can work together to achieve efficient and precise tile leveling.

[0035] The upper transmission block 20, serving as the power input end, is unique in that it can rotate in response to external driving forces. In practical applications, this external drive typically originates from electric power mechanisms, such as electric drills or electric pulleys, which are connected to the upper transmission block 20 via specific interfaces or transmission methods to drive its rotation. To achieve seamless integration with these electric power mechanisms, the upper transmission block 20 is specifically designed for compatibility, equipped with a connection structure that matches the electric power mechanism, ensuring stable and efficient power transmission.

[0036] A torque overload cutoff structure is cleverly designed between the lower transmission block 40 and the upper transmission block 20. Under normal operating conditions, i.e., when the torque is within a light load range, the rotation of the upper transmission block 20 smoothly drives the lower transmission block 40 to rotate synchronously, achieving normal torque transmission. However, when the torque exceeds a preset safety threshold, i.e., an overload occurs, this torque connection mechanism automatically cuts off to prevent equipment damage or safety accidents. For example, this torque overload cutoff structure employs a friction-based design. Static friction is formed between the upper transmission block 20 and the lower transmission block 40 through surface contact. When the torque is low, this static friction is sufficient to maintain their synchronous rotation; however, when the torque increases to a certain extent, the static friction is insufficient to overcome the torque effect, causing slippage between them, thus cutting off torque transmission.

[0037] The connecting sleeve 70, as a key component for torque transmission and output, has a dual function: on the one hand, it receives torque from the lower transmission block 40; on the other hand, it connects to the tile leveling device through a specific connection structure, outputting torque to the leveling device to drive it in operation. To achieve this function, the connecting sleeve 70 is designed to either connect directly to the lower transmission block 40 or integrate the two into one unit, simplifying the structure and improving efficiency. Furthermore, for different types of tile leveling devices (such as the device described in Chinese patent document CN118911388A or similar solutions), the connecting sleeve 70 is also designed with corresponding mating structures to ensure a tight connection and efficient transmission with the leveling device.

[0038] This embodiment serves as the basic version of the entire solution, providing a solid foundation for advanced optimizations in subsequent embodiments.

[0039] Example 2

[0040] Example 2 details another improved power-assisted tile leveling mechanism, which features significant innovations based on Example 1. The core improvement focuses on the design of the torque overload cutoff structure. This torque overload cutoff structure is cleverly integrated into the interaction mechanism between the upper transmission block 20 and the lower transmission block 40, specifically manifested as a ratchet structure on their opposing surfaces. Under normal torque load, these ratchet teeth can mesh tightly, ensuring smooth power transmission; however, once the torque exceeds the preset safety range, the ratchet teeth will automatically disengage to cut off the torque transmission.

[0041] Specifically, the unique shape design of the ratchet teeth is key to their functionality. Each ratchet tooth is positioned along the direction of force (e.g., in...). Figure 5 The clockwise direction shown in the diagram contains three feature surfaces in sequence: first, a monotonically rising ramp to guide smooth meshing between the ratchet teeth under light torque loads to transmit torque; next, a plane parallel to the direction of force; and finally, a vertical surface perpendicular to the direction of force.

[0042] In this embodiment, the upper transmission block 20 is precisely positioned directly above the lower transmission block 40 in the tile leveling power assist mechanism (based on...). Figure 1 , Figure 2 (as shown in the diagram), therefore, the opposing surfaces specifically refer to the lower end surface of the upper transmission block 20 and the upper end surface of the lower transmission block 40. Further refinement, such as... Figure 5 , Figure 6 As shown, three upper ratchet teeth 21 are evenly distributed on the lower end face of the upper transmission block 20. They are arranged at equal angles (i.e., 120°) around the rotation axis of the upper transmission block 20, and each upper ratchet tooth 21 follows the aforementioned shape design principle.

[0043] Correspondingly, the upper end face of the lower transmission block 40 is also designed with a lower ratchet 41 that matches the upper ratchet 21. The two are consistent in shape, structure, position and number to ensure high synergy in the torque transmission process.

[0044] During torque transmission, the engagement state between the upper transmission block 20 and the lower transmission block 40 dynamically changes with the magnitude of the torque. When the torque is within the light load range, the inclined surfaces of the upper ratchet 21 and the lower ratchet 41 closely interlock, forming an effective mesh, thus ensuring smooth torque transmission. However, once the torque exceeds the safety threshold, relative sliding will occur between the inclined surfaces of the upper ratchet 21 and the lower ratchet 41, causing the distance between the lower end face of the upper transmission block 20 and the upper end face of the lower transmission block 40 to gradually increase until the plane of the upper ratchet 21 contacts the plane of the lower ratchet 41. At this point, the meshing relationship completely fails, and torque transmission is automatically cut off. As the upper transmission block 20 continues to rotate, the upper ratchet 21 and the lower ratchet 41 will cross the vertical surface and fall back into the gap between the opposing ratchets, preparing for the next meshing.

[0045] This design offers two significant advantages: First, by varying the relative displacement between the upper transmission block 20 and the lower transmission block 40, the function of precisely controlling torque transmission at a specific threshold is achieved. Second, the coefficient of friction between the inclined surfaces of the upper ratchet 21 and the lower ratchet 41, as a key factor affecting the torque threshold, can be flexibly adjusted by modifying parameters such as the material of the upper transmission block 20 and the lower transmission block 40, the roughness of the inclined surfaces, and the angle of the inclined surfaces, to meet the actual needs of different application scenarios.

[0046] Same as Example 1.

[0047] Example 3

[0048] Example 3 presents another type of tile leveling power auxiliary mechanism, which is a more refined improvement on the basis of Example 2. These improvements are mainly reflected in the newly added components, including the upper drive shaft 10, the lower drive shaft 50, the spring 60, and the outer sleeve 30.

[0049] like Figure 3 , Figure 4 as well as Figure 7 As shown, the upper drive shaft 10 plays a crucial role. Its lower end is securely connected to the upper drive block 20, while its upper end is meticulously designed to be compatible with electric rotary tools. In this embodiment, the upper drive shaft 10 is cleverly designed as a regular hexagonal prism, a design that allows its upper end to perfectly fit the drill bit chuck of a pistol drill, greatly facilitating the operator's work. Simultaneously, to achieve a tight connection between the upper drive shaft 10 and the upper drive block 20, a hole is specially provided on the upper part of the upper drive block 20 so that the lower end of the upper drive shaft 10 can be tightly inserted into it. In this way, when the pistol drill bit begins to rotate, the upper drive block 20 rotates synchronously, achieving efficient power transmission.

[0050] The lower drive shaft 50 also adopts a regular hexagonal prism design, with its upper end fitted into the regular hexagonal lower drive shaft mounting hole 42 in the lower drive block 40 (see details). Figure 6 The lower end is inserted into the hole above the connecting sleeve 70. It is worth noting that the lower drive shaft 50 and the lower drive shaft mounting hole 42 adopt a clearance sleeve connection. This design allows the lower drive block 40 to maintain a liftable state while achieving torque connection with the lower drive shaft 50, providing the possibility for flexible operation of the mechanism.

[0051] Spring 60 plays a crucial role in the mechanism, acting as a buffer and resetting mechanism. Its lower end abuts against the connecting sleeve 70, while its upper end abuts against the lower transmission block 40. The connecting sleeve 70 is specially designed with a shoulder, which is used to limit and accommodate spring 60. When the mechanism is subjected to downward pressure, the lower transmission block 40 will move downward against the elastic force of spring 60; and when the downward pressure disappears, the lower transmission block 40 will spring back upward under the elastic force of spring 60, thus realizing the automatic resetting function of the mechanism.

[0052] The outer sleeve 30 is cylindrical in shape with a slightly smaller opening at the top. This design allows the outer sleeve 30 to perfectly cover a portion of the upper drive shaft 10, most of the upper drive block 20, the lower drive shaft 50, the lower drive block 40, the spring 60, and the connecting sleeve 70. In this embodiment, the outer wall of the outer sleeve 30 is designed as a regular octagonal prism, and the lower opening is also a regular octagonal prism, matching the shape and size of the regular octagonal prism of the outer wall of the connecting sleeve 70, allowing the connecting sleeve 70 to fit snugly into the lower opening of the outer sleeve 30. Furthermore, the lower opening of the outer sleeve 30 is specially equipped with a flared guide structure, which greatly facilitates the quick insertion of the outer sleeve 30 into the second component of the tile leveling device. Simultaneously, two blind holes are symmetrically provided on the side wall of the connecting sleeve 70, while two through holes are provided at corresponding positions on the outer sleeve 30. By having the sleeve fixing pin 80 pass through one blind hole and one through hole simultaneously, the inner and outer fixing of the outer sleeve 30 and the connecting sleeve 70 can be achieved. In this embodiment, the sleeve fixing pin 80 has a smooth rod design on its inner end and a spline design on its outer end. The spline and the through hole of the outer sleeve 30 adopt an interference fit to ensure the stability of the fixation.

[0053] The rest remains consistent with Example 2, ensuring the continuity and stability of the mechanism design.

[0054] This embodiment is undoubtedly the more complete and preferred solution in this scheme. In this embodiment, torque is input through the upper drive shaft 10, and the precise transmission of torque is achieved by the meshing relationship between the upper ratchet 21 and the lower ratchet 41. When the torque is under light load, the torque transmission proceeds normally, and the upper drive shaft 10 sequentially drives the upper drive block 20, the lower drive block 40, the lower drive shaft 50, the connecting sleeve 70, and the outer sleeve 30 to rotate synchronously. However, when the torque is overloaded, the inclined plane action of the upper ratchet 21 and the lower ratchet 41 will cause the lower drive block 40 to move downward against the elastic force of the spring 60, resulting in slippage between the upper ratchet 21 and the lower ratchet 41. The upper ratchet 21 climbs above the lower ratchet 41, thereby cutting off the torque transmission path, but ultimately ensuring that the maximum torque output of the connecting sleeve 70 remains unchanged, thus realizing the torque overload protection function.

[0055] Example 4

[0056] Example 4 is a meticulously designed tile leveling kit that cleverly integrates the tile leveling power assist mechanism described in Example 3 and the tile leveling device described in detail in Chinese patent document CN118911388A. Figure 8 The overall structure of the tile leveling device is shown in a visual way. Figure 9 This depicts the perfect cooperation between the tile leveling power auxiliary mechanism and the tile leveling device in this embodiment. Figure 10 The internal structure of this embodiment in its working state is clearly presented through an axial sectional view.

[0057] Specifically, the tile leveling device mainly consists of a first component 100, a second component 200, and a third component (although not explicitly shown in the figure, its existence and important role are known from the patent literature description). Among them, the first component 100 is stably connected to the second component 200 through a precise threaded structure, ensuring the overall stability of the device.

[0058] The upper connecting part of the second component 200 is a regular octagonal prism, and the internal opening of the connecting sleeve 70 is also a regular octagonal prism, which can cleverly form a torque connection with the second component 200, so that the torque can be smoothly transmitted.

[0059] With this kit, construction workers can easily operate using a hand drill, which not only greatly saves labor costs but also significantly improves work efficiency. More importantly, the kit can apply a uniform maximum torque to the second component 200, thereby ensuring the consistency of the flatness positioning during the tile leveling process, and thus guaranteeing that the tile Z will achieve an ideal flatness.
