Description

Technical Field

[0001] This utility model relates to the field of floor maintenance and support technology, and in particular to a floor repair and support mechanism. Background Technology

[0002] Floor support mechanisms are used to provide stable support for floors during installation, renovation, or troubleshooting, ensuring that workers can carry out their work safely and efficiently. When problems such as cracking, deformation, or warping occur in the floor, repair personnel need to lift the floor section for repair or replacement. Floor support mechanisms play a crucial role in this process, replacing traditional manual support methods and avoiding instability caused by insufficient manpower. Furthermore, the support height and angle can be flexibly adjusted according to different repair needs, improving the convenience and safety of repair work.

[0003] Most existing floor repair support mechanisms use a combination of slots and blocks to achieve height adjustment. During operation, the blocks can be inserted into slots at different heights. This plug-and-play structure avoids the time-consuming and cumbersome problems of traditional screw adjustment methods, enabling rapid height adjustment of the support mechanism and significantly improving repair efficiency. However, due to the limitations of the slot and block structure design, the precision of height adjustment cannot meet the needs of some delicate repair operations. The slots are pre-cut on the support body at fixed intervals, and the blocks can only be locked in these fixed positions. When repair personnel need to support the floor to a specific height between two adjacent slots, this cannot be achieved. This slot and block structure is difficult to make minute height adjustments when dealing with complex ground environments, and cannot guarantee that the floor is in an absolutely level state, affecting the repair effect and reducing work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a floor repair support mechanism, which aims to improve the problem that the existing slot and block structure is difficult to make slight height adjustments when dealing with complex ground environments, cannot guarantee that the floor is in an absolutely level state, affects the repair effect, and leads to reduced work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a floor repair support mechanism, including a support sleeve, an adjustment mechanism is provided inside the support sleeve, the adjustment mechanism is used for coarse height adjustment, a connecting plate is fixedly connected to the top of the adjustment mechanism, and a fine adjustment mechanism is provided on the top of the connecting plate, the fine adjustment mechanism is used for fine adjustment of the support height; The fine-tuning mechanism includes a threaded rod, the outer wall of which is threadedly connected to the top of a connecting plate. A threaded hole is provided on the top of the connecting plate. The outer side of the threaded rod is threadedly connected to the inner side of the threaded hole. A connecting rod is fixedly connected to the top of the threaded rod. A circular hole is provided on the front side of the connecting rod. A rotating component is provided on the top of the connecting rod. A connecting component is provided on the top of the rotating component.

[0006] As a further description of the above technical solution: The adjustment mechanism includes a sliding rod, which is slidably connected to the outside of the support sleeve. The front side of the outer wall of the support sleeve has multiple adjustment holes. The bottom two adjustment holes are slidably connected to pins. The rear side of the two pins is threaded with bolts. The middle of the outer wall of the two bolts is fixedly connected to a limit plate.

[0007] As a further description of the above technical solution: The rotating assembly includes multiple fixed rods, the bottom of which is fixedly connected to the top of the circular hole, and the top of which is fixedly connected to the same washer, with a fixed post fixedly connected inside the washer.

[0008] As a further description of the above technical solution: The connecting assembly includes a top plate, which is internally rotatably connected to the middle of the outer wall of the fixed column. Threaded holes are provided at the four corners of the top of the top plate.

[0009] As a further description of the above technical solution: The top of the connecting component has a groove, and the interior of the groove is designed to be narrower at the bottom and wider at the top.

[0010] As a further description of the above technical solution: The bottom of the support sleeve is fixedly connected to a base plate, and the base plate has reserved holes at the four corners of the top.

[0011] This utility model has the following beneficial effects: 1. In this utility model, a threaded pair is formed by the threaded rod and the threaded hole. Rotating the threaded rod drives the connecting rod and the connecting assembly to rise and fall, thereby achieving precise height adjustment. The outer ring of the washer is fixed, and the inner ring is interference-fitted with the shaft of the connecting assembly, allowing the connecting assembly to rotate flexibly. This enables precise adjustment of the support height and flexible angle adaptation during floor maintenance, making operation convenient and effectively avoiding secondary damage caused by unstable support, thus improving the efficiency and reliability of maintenance work.

In this utility model, by loosening the bolt to allow the pin to exit the adjustment hole, the sliding rod is released from locking, and the sliding rod is pushed to slide within the support sleeve to adjust the height. After adjustment, the pin is inserted and the bolt is tightened to fix it. This achieves rapid coarse adjustment of the floor repair support height, ensuring stability while adjusting the height over a wide range, reducing adjustment resistance, making the operation smoother, adapting to the repair needs of floors of different thicknesses, and improving repair efficiency and support reliability.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 and Figure 4 The present invention provides an embodiment of a floor repair support mechanism, comprising a support sleeve 1, an adjustment mechanism 2 provided inside the support sleeve 1, the adjustment mechanism 2 being used for coarse height adjustment, a connecting plate 3 being fixedly connected to the top of the adjustment mechanism 2, and a fine adjustment mechanism 4 being provided on the top of the connecting plate 3, the fine adjustment mechanism 4 being used for fine adjustment of the support height. The fine-tuning mechanism 4 includes a threaded rod 42, the outer wall of which is threadedly connected to the top of the connecting plate 3. The top of the connecting plate 3 has a threaded hole 41. The outer side of the threaded rod 42 is threadedly connected to the inner side of the threaded hole 41. A connecting rod 43 is fixedly connected to the top of the threaded rod 42. A round hole 44 is opened on the front side of the connecting rod 43. A rotating component 45 is provided on the top of the connecting rod 43. A connecting component 46 is provided on the top of the rotating component 45. Specifically, the fine-tuning mechanism 4 uses a threaded rod 42 as its core transmission component. Its outer wall forms a threaded pair with the threaded hole 41 at the top of the connecting plate 3. A connecting rod 43 is fixed to the top of the threaded rod 42, and a circular hole 44 is opened on its front side. The top is connected to the connecting assembly 46 via a rotating assembly 45. The rotating assembly 45 includes a washer 452, the outer ring of which is fixed to the groove 5 at the top of the connecting rod 43, and the inner ring is interference-fitted with the rotating shaft at the bottom of the connecting assembly 46, allowing the connecting assembly 46 to rotate around the washer 452. During height fine-tuning, rotating the threaded rod 42 clockwise causes it to move axially upwards due to the constraint of the threaded hole 41, driving the connecting rod 43 and the connecting assembly 46 to rise synchronously. Counterclockwise rotation causes it to descend. Hole 44 is used to insert a wrench, increasing the force application radius and reducing the adjustment torque. The ball bearing design of the washer 452 reduces the coefficient of rotational friction, ensuring smooth rotation of the connecting component 46 and adapting to the fitting needs of different angle flooring. The thread self-locking property of the threaded rod 42 and threaded hole 41 prevents the support height from changing due to vibration. The thread transmission between the threaded rod 42 and threaded hole 41 enables precise adjustment of the support height. The rotating connection of the washer 452 enables flexible rotation of the connecting component 46. The wrench interface design of the round hole 44 improves the convenience of adjustment operation, meeting the needs of flooring maintenance for accurate support height and flexible fitting, and avoiding secondary damage caused by unstable support.

[0017] Reference Figure 1 , Figure 2 and Figure 3 The adjustment mechanism 2 includes a sliding rod 21, which is slidably connected to the outside of the support sleeve 1. Multiple adjustment holes 22 are provided on the front side of the outer wall of the support sleeve 1. Pins 23 are slidably connected to the inside of the two bottom adjustment holes 22. Bolts 24 are threadedly connected to the rear side of the two pins 23. Limiting plates 25 are fixedly connected to the middle of the outer wall of the two bolts 24. Specifically, the adjusting mechanism 2 uses a sliding rod 21 as the lifting body. Its outer diameter is clearance-fitted with the inner diameter of the support sleeve 1 to ensure that the sliding rod 21 can slide smoothly inside the support sleeve 1. Multiple adjusting holes 22 are opened on the front side of the outer wall of the support sleeve 1. The two bottom adjusting holes 22 are used to insert pins 23. A hole is opened on the rear side of the pin 23 for threaded connection with the bolt 24. A limiting plate 25 is fixed in the middle of the outer wall of the bolt 24 to limit the insertion depth of the pin 23 and prevent the pin 23 from completely entering the support sleeve 1. When adjusting the height, first loosen the bolt 24 to make the pin 23 exit from the adjusting hole 22, releasing the locking state of the sliding rod 21. Then, push it up or down according to the required support height. When the positioning hole on the sliding rod 21 is aligned with the target adjustment hole 22 on the support sleeve 1, the pin 23 is inserted into the adjustment hole 22 and the positioning hole, and then the bolt 24 is tightened, so that the limiting plate 25 presses against the outer wall of the support sleeve 1. Through the dual action of friction and threaded pair, the pin 23 is ensured to be firmly fixed, preventing the sliding rod 21 from shifting. Through the sliding cooperation between the sliding rod 21 and the support sleeve 1, a wide range of support height adjustment is achieved. Through the positioning and locking of the pin 23 and the adjustment hole 22, the stability of the adjusted height is ensured. This meets the need for quick and coarse adjustment of support height during floor maintenance, while ensuring the stability of the support structure and adapting to maintenance scenarios of floors of different thicknesses.

[0018] Reference Figure 4 and Figure 5 The rotating assembly 45 includes multiple fixing rods 451, the bottom of which is fixedly connected to the top of the round hole 44, and the top of which is fixedly connected to the same gasket 452. The connecting assembly 46 includes a top plate 461, the interior of which is rotatably connected to the middle of the outer wall of the fixing column 453. Threaded holes 462 are provided at the four corners of the top of the top of the top plate 461. A groove 5 is provided at the top of the connecting assembly 46. The interior of the groove 5 adopts a design that is narrow at the bottom and wide at the top. The bottom of the support sleeve 1 is fixedly connected to a base plate 6. Reserved holes 7 are provided at the four corners of the top of the base plate 6. Specifically, the rotating assembly 45 is supported by multiple fixed rods 451. The bottom of the rods is welded to the edge of the top circular hole 44 of the connecting rod 43, and the top is fixed with a washer 452. The inner ring of the washer 452 is interference-fitted with a fixed post 453, and the outer ring is welded to the top of the fixed rod 451, forming a stable rotating support structure. Threaded holes 462 are opened at the four corners of the top plate 461 for threaded connection to the floor requiring support. The groove 5 at the top of the top plate 461 adopts a trapezoidal cross-section design that is narrower at the bottom and wider at the top. When the support angle needs to be adjusted, the operator can directly push the top plate 461 to rotate it around the axis of the fixed rod 451. The washer 452 prevents the top plate 461 from loosening, ensuring smooth rotation of the top plate 461. The even distribution of the fixing rods 451 provides stable support and prevents uneven stress on the gaskets 452. When installing external connectors, the combination of the fixing rods 451 and the gaskets 452 enables low-resistance rotation of the top plate 461. The trapezoidal cross-section design of the groove 5 and the fit with the threaded hole 462 enable quick installation and stable connection of the external connectors, meeting the needs for flexible adjustment of the support angle and reliable connection during floor maintenance, and improving the convenience and efficiency of maintenance operations. The base plate 6 is fixed to the bottom of the support sleeve 1, and the reserved holes 7 at the four corners of the top are used for insertion to fix the support mechanism to the ground. The position of the reserved holes 7 matches the standard spacing, which facilitates quick installation and ensures long-term reliability.

[0019] Working principle: First, place the base plate 6 at the bottom of the support sleeve 1 on the ground maintenance area. The pre-drilled holes 7 at the four corners of the top of the base plate 6 are used to insert expansion bolts 24. The operator drills holes in the ground according to the positions of the pre-drilled holes 7, then passes the expansion bolts 24 through the holes 7 and tightens them, firmly connecting the base plate 6 to the ground, completing the initial fixing of the support mechanism and ensuring that the support mechanism will not shift during subsequent operations. After the support mechanism is fixed, coarse height adjustment begins. The sliding rod 21 of the adjustment mechanism 2 is initially located inside the support sleeve 1. Multiple adjustment holes 22 are opened on the front side of the outer wall of the support sleeve 1. Pins 23 are inserted into the two bottom adjustment holes 22. The rear side of the pins 23 is connected to the limiting plate 25 by bolts 24. The operator uses a wrench to loosen the bolts 24, causing the pins 23 to exit from the adjustment holes 22, releasing the sliding rod 21. 1. Locking: According to the height of the floor to be repaired, push the sliding rod 21 up or down. When the positioning hole on the sliding rod 21 is aligned with the target adjustment hole 22 on the support sleeve 1, insert the pin 23 into the adjustment hole 22 and the positioning hole, and then tighten the bolt 24. The limiting plate 25 presses against the outer wall of the support sleeve 1. The pin 23 is fixed by the dual action of friction and threaded pair, and the coarse height adjustment is completed, realizing a wide range of support height adjustment. After the coarse adjustment is completed, the height is precisely adjusted by the fine adjustment mechanism 4. The threaded rod 42 of the fine adjustment mechanism 4 and the threaded hole 41 at the top of the connecting plate 3 form a threaded pair. The connecting rod 43 is fixed at the top of the threaded rod 42, and a round hole 44 is opened on the front side. The operator inserts the wrench into the round hole 44 and rotates the threaded rod 42 clockwise. The threaded rod 42 moves upward along the axis, driving the connecting rod 43 and the connecting assembly 46 to rise.Rotating counterclockwise lowers the support, allowing for precise adjustment of the support height. After adjustment, the rotating component 45 and the connecting component 46 are fitted together at an angle. The bottoms of the multiple fixing rods 451 of the rotating component 45 are welded to the top of the connecting rod 43, and a top fixing pad 452 is provided. The top plate 461 of the connecting component 46 is fitted onto the outer wall of the fixing rod 451 through a central through hole and can rotate around the axis of the fixing rod 451. The operator pushes the top plate 461 to rotate it around the fixing rod 451 until the top of the top plate 461 is flush with the bottom of the floor to be repaired. The top plate 461 has a trapezoidal cross-section design with a narrow bottom and a wide top, and the floor to be repaired is fixed by the connecting component 46. The threaded holes 462 at the four corners of the top of the top plate 461 are used to connect with the floor. The operator passes the connecting bolt 24 through the mounting hole on the floor, screws it into the threaded hole 462 and tightens it to make the floor and the top plate 461 firmly connected. Because the threads of the threaded rod 42 and the threaded hole 41 are self-locking, the support height will not change due to vibration. At the same time, the rotating component 45 ensures that the top plate 461 is securely connected. 1. The support mechanism fits snugly against the floor, providing stable support. After maintenance, when disassembling the support mechanism, first loosen the connecting bolt 24 to separate the floor from the top plate 461. Then, rotate the threaded rod 42 counterclockwise with a wrench to lower the connecting component 46 to its initial position. Next, loosen the bolt 24 of the adjusting mechanism 2, pull out the pin 23, and push the sliding rod 21 downwards to fully retract it into the support sleeve 1. Finally, loosen the bolt 24 to remove the support mechanism from the ground. The adjusting mechanism 2 achieves rapid and stable coarse height adjustment through the sliding fit between the sliding rod 21 and the support sleeve 1, and the locking of the pin 23 and the adjusting hole 22. The fine adjustment mechanism 4 achieves precise height adjustment through the threaded transmission between the threaded rod 42 and the threaded hole 41. The rotating component 45 and the connecting component 46 are connected by a rotating washer 452 and a threaded connection to achieve angle adaptation and floor fixation. This meets the requirements for stability, adjustment accuracy, and ease of operation during floor maintenance, effectively avoiding secondary damage to the floor due to unstable support, and improving the efficiency and quality of floor maintenance.
