Description

Technical Field

[0001] The present application relates to the technical field of wall decoration, and in particular to an assembled wall keel leveling system. Background Art

[0002] As the structural framework for wall decoration, wall studs play multiple key roles. Through rational layout and fixing, they provide reliable support for decorative panels, ensuring their flatness and stability, preventing deformation and falling. They effectively distribute the load borne by the wall, enhancing the overall stability and strength of the wall. They can also be shaped into various shapes based on design requirements, achieving diverse decorative effects. Furthermore, the space created between the studs and the wall facilitates the concealed installation of plumbing and other facilities, enhancing the aesthetics and practicality of the space.

[0003] A search revealed a Chinese patent document that discloses a leveling, assembled wall keel structure [Application Number: CN201920976245.6; Publication Number: CN210288975U]. This wall keel structure comprises a wall panel, a leveling base fixedly connected to the wall, a leveling member threadedly connected to the leveling base, a curved outer surface with radial grooves along its outer circumference, a keel with hooks at its upper and lower ends along its width, the hooks engaging the grooves, and a hanger fixed to the wall panel and hooked to the leveling member and the keel. The keel and the wall are movably connected. When leveling the keel, there is no need to disassemble it. You only need to rotate the leveling piece to change its front and rear position. It is easy to install and more convenient to level. However, the keel is generally connected to the wall through multiple connecting seats. When adjusting the keel, the above device needs to adjust each leveling base synchronously to achieve the adjustment of the keel. In actual operation, it is difficult to adjust multiple leveling bases synchronously, and the operation is difficult. Summary of the Invention

[0004] In order to reduce the difficulty of adjusting the wall keel, the present application provides an assembled wall keel leveling system.

[0005] The present application provides an assembled wall keel leveling system that adopts the following technical solutions:

[0006] An assembled wall keel leveling system includes a leveling base fixed to the wall, the leveling base is N-shaped, a sliding hole is provided in the middle position of the leveling base, a plurality of circumferentially evenly distributed protrusions are provided on the inner side of the sliding hole, a threaded rod is slidably provided in the sliding hole, and a groove matching the protrusion is provided on the outer side of the threaded rod, a fastening ring is threadedly connected to the threaded rod, and the fastening ring abuts against the inner side of the leveling base, an end of the threaded rod close to the wall is connected to a tightening block, and the tightening block abuts against the wall, an adjusting sleeve is threadedly connected to the threaded rod, and the end of the adjusting sleeve is rotatably connected to a connecting seat, and the connecting seat is connected to the keel.

[0007] The two connecting points of the leveling base can be rotated along the center to fix it in a position where the wall anchoring force is stronger. Then the fastening ring is rotated forward so that the fastening ring is against the inner side of the leveling base, and the threaded rod is pulled toward the wall through the action of the threaded connection so that the tightening block is against the wall, thereby locking the position of the threaded rod. Then, the connecting seat and the keel can be connected. After installation, when adjusting the keel, when the keel is connected to multiple connecting seats, the fastening rings on the middle several leveling bases can be rotated in the opposite direction to separate them from the inner wall of the leveling base, and then the adjusting sleeve can be rotated in the opposite direction. Since the adjusting sleeve is connected to the keel through the connecting seat, the two ends of the keel are still fixed at this time, the adjusting sleeve can only rotate and cannot move. At this time, rotating the adjusting sleeve in the opposite direction can drive the threaded rod to move in the direction close to the adjusting sleeve, thereby making the tightening block and When the adjusting block is in contact with the wall, the fastening ring is rotated forward so that the fastening ring contacts the inner wall of the leveling base, and the threaded rod and the leveling base can be locked again. When adjusting the keel, the fastening ring and the adjusting sleeve in the middle position, and the fastening ring and the adjusting sleeve at both ends can be operated in sequence. There is no need to adjust at the same time, which is more convenient to operate.

[0008] Preferably, a circular hole is provided in the middle of the adjusting sleeve, and the circular hole is coaxial with the adjusting sleeve, a long hole is provided in the middle of the threaded rod, and the long hole is coaxial with the circular hole, a rotating rod is rotatably arranged in the long hole, and the tightening block is fixed to the end of the rotating rod, the outer side of the tightening block is a polygonal column structure, and a polygonal inner groove matching the outer shape of the tightening block is provided on the inner side of the fastening ring, and the tightening block is slidably arranged in the polygonal inner groove, a semi-synchronous transmission mechanism and a fully synchronous transmission mechanism are provided between the end of the rotating rod away from the tightening block and the adjusting sleeve, and a damping structure is provided between the adjusting sleeve and the connecting seat.

[0009] By adopting the above technical solution, when the fastening ring is rotated in the opposite direction, the fastening ring will synchronously drive the clamping block to rotate in the opposite direction, and the clamping block will drive the rotating rod to rotate in the opposite direction. At this time, through the transmission of the semi-synchronous transmission mechanism, the number of reverse rotations of the adjusting sleeve is half of the number of reverse rotations of the rotating rod. In the half stroke when the rotating rod and the adjusting sleeve rotate synchronously in the opposite direction, since the adjusting sleeve cannot move, the fastening ring does not move either, but the threaded rod and the clamping block move in the direction away from the wall. In the half stroke when the rotating rod rotates in the opposite direction and the adjusting sleeve does not rotate, since the adjusting sleeve cannot move, the threaded rod does not move either. At this time, only the fastening ring moves in the direction close to the wall. Therefore, after the entire stroke is completed, the fastening ring and the clamping block are respectively away from the leveling base and the wall, the threaded rod and the leveling base are released, and the fixation in the middle of the keel is released. The operator only needs to rotate the fastening ring in the opposite direction. The tightening ring and the adjusting sleeve need to be rotated separately, and there is no need to adjust the stroke difference between the two, which makes the operation more convenient. Moreover, after adjusting the position of the keel, when the threaded rod needs to be locked with the leveling base again, it is only necessary to rotate the tightening ring forward, and the tightening ring drives the tightening block to rotate forward, and the tightening block drives the rotating rod to rotate forward. Through the transmission of the fully synchronous transmission mechanism, the rotating rod and the adjusting sleeve first rotate forward synchronously with the tightening ring. At this time, the threaded rod moves in the direction close to the wall until it is against the wall. Then the fully synchronous transmission mechanism stops transmission, and the tightening ring continues to rotate forward. At this time, the threaded rod does not move, and the tightening ring moves in the direction close to the leveling base, and finally against the leveling base, and the threaded rod can be locked with the leveling base again. It is only necessary to rotate the tightening ring forward. There is no need to rotate the adjusting sleeve and the tightening ring forward separately, and there is no need to consider the number of rotations of the two. The operation is simpler.

[0010] Preferably, the damping structure includes a damping rubber ring, an embedding groove is provided on one end surface of the adjustment sleeve close to the connecting seat, and the damping rubber ring is fixed in the embedding groove, and the other side of the damping rubber ring is against the connecting seat.

[0011] By adopting the above technical solution, under the action of the damping rubber ring, the rotation between the adjustment sleeve and the connecting seat has a certain friction force. When the rotational force is less than the friction force, the adjustment sleeve and the connecting seat will maintain synchronous rotation or relative stillness.

[0012] Preferably, the semi-synchronous transmission mechanism includes a first telescopic tongue, a first mounting groove is provided on the outer side of the rotating rod, and the first telescopic tongue is slidably arranged in the first mounting groove, and first limit blocks for preventing falling off are provided on both sides of the first telescopic tongue, and a first elastic member for pushing the first telescopic tongue outward is provided at the bottom of the first mounting groove, a first chamfer is provided on one side of the outer side of the first telescopic tongue, two symmetrically distributed extension blocks are provided on the inner side of the circular hole, a fixing bar is fixed to the inner side of the connecting seat, and a boss is provided on the fixing bar. When the rotating rod rotates, the first telescopic tongue will shrink when passing through the boss.

[0013] By adopting the above technical solution, when the fastening ring rotates in the opposite direction, the tightening block and the rotating rod rotate in the opposite direction synchronously. During the rotation process, the rotating rod will cause the first telescopic tongue to abut against one side of the extension block and drive the adjusting sleeve to rotate in the opposite direction synchronously through the extension block. When the first telescopic tongue rotates to the position of the boss, the first telescopic tongue contracts and separates from the extension block. At this time, no thrust is generated on the extension block, so the adjusting sleeve stops rotating. After the first telescopic tongue passes over the boss, it extends outward under the elastic force of the first elastic member, and then continues to rotate in the opposite direction. When the first telescopic tongue rotates half a circle, it will abut against the other extension block and continue to drive the adjusting sleeve to rotate in the opposite direction half a circle. This is repeated, so that the adjusting sleeve can be driven to rotate in the opposite direction half a circle for every one circle of the rotating rod in the opposite direction.

[0014] The locking mechanism can be adjusted by adjusting the angles on the cam face to move the second end of the lever to the left, while the locking mechanism can be adjusted by adjusting the angles on the cam face to move the second end of the lever to the left.

[0015] By adopting the above technical solution, when the fastening ring rotates forward, one of the second telescopic tongues will press against the side of the extension block and drive the adjusting sleeve to rotate forward. When the second telescopic tongue passes the boss, the second telescopic tongue will shrink and pass over the boss. At this time, the second telescopic tongue will break away from the extension block, but then when the rotating rod rotates forward a smaller angle, the other second telescopic tongue will press against the other extension block and continue to drive the adjusting sleeve to rotate forward. Therefore, the rotating rod and the adjusting sleeve can basically achieve synchronous forward rotation. After the two rotate forward for a certain distance, the extrusion plate will press against the wall, and as the threaded rod and the rotating rod continue to move toward the wall, the triangular groove will hook the triangular block. As the rotating rod moves, the triangular groove pulls the triangular block and pulls the second elastic member toward the bottom of the second mounting groove, so that the second telescopic tongue moves toward the second mounting groove. When the first telescopic tongue is pressed against the extension block, the adjusting sleeve will stop rotating. Even if the first telescopic tongue is pressed against the extension block, the adjusting sleeve will be subjected to rotational resistance under the action of the damping rubber ring, and the first telescopic tongue will be contracted into the first mounting groove under the action of the first chamfer and pass over the extension block. Similarly, during the reverse rotation of the rotating rod, within the half circle in which the rotating rod rotates in the reverse direction and the adjusting sleeve does not rotate, even if the second telescopic tongue is pressed against the extension block, the adjusting sleeve will be subjected to rotational resistance under the action of the damping rubber ring, and the second telescopic tongue will be contracted into the second mounting groove under the action of the second chamfer and pass over the extension block. Therefore, the semi-synchronous transmission mechanism and the fully synchronous transmission mechanism will not interfere with each other.

[0016] Preferably, the first elastic member and the second elastic member are both elastic metal sheets, and the middle position of the elastic metal sheet respectively abuts against the first telescopic tongue and the second telescopic tongue, and the two ends of the elastic metal sheet respectively abut against the bottom of the first installation groove and the second installation groove.

[0017] By adopting the above technical solution, the elastic parts of the first elastic member and the second elastic member have the same structure, and the elastic metal sheet can not only provide elastic force but also occupy less space.

[0018] Preferably, a plurality of guide holes are provided on the side of the pressing block close to the extrusion plate, a plurality of guide rods are fixed on the extrusion plate, and the guide rods are slidably inserted in the guide holes, a spring groove is provided on the side center of the pressing block close to the extrusion plate, and a support spring is provided in the spring groove, and the two ends of the support spring are respectively against the extrusion plate and the bottom of the spring groove.

[0019] By adopting the above technical solution, when the extrusion plate is attached to the wall and the clamping block approaches or moves away from the wall, the guide rod and the guide hole can ensure the smooth sliding between the extrusion plate and the clamping block, and will not cause the slider to get stuck. Moreover, under the support of the support spring, when the clamping block moves away from the wall, the extrusion plate and the clamping block can be automatically separated, so that the triangular block is detached from the triangular groove, further preventing the device from getting stuck and improving the smoothness of use.

[0020] Preferably, two accommodating grooves are provided on the inner side of the circular hole, and the extension block is slidably arranged in the accommodating groove, a connecting hole is provided at the bottom of the accommodating groove, and the connecting hole extends to the outside of the adjusting sleeve, a pull rod is slidably provided in the connecting hole, one end of the pull rod is fixed to the extension block, and the other end extends to the outside of the adjusting sleeve and is fixed with a support rod, two symmetrically distributed connecting ears are fixed on the outer wall of the adjusting sleeve, and a rotating shaft is rotatably provided on the connecting ears, a handle is fixed to one end of the rotating shaft, and an end face of the other end is provided with an arc groove from the edge to the center, and the end of the support rod is inserted in the arc groove.

[0021] By adopting the above technical solution, when adjusting the two ends of the keel or during the initial installation, when rotating the adjustment sleeve forward or reversely when the threaded rod is locked with the leveling base, the two handles can be first spread out to both sides. During the spreading process, the rotating shaft will rotate. At this time, the arc groove will pull the pull rod outward through the support rod. The pull rod can be moved outward to retract the extension block into the accommodating groove. Then, the adjustment sleeve can be rotated forward or reversely by using the two handles. At this time, the extension block has no contact with the first telescopic tongue and the second telescopic tongue, and will not drive the rotating rod to rotate, nor will it drive the fastening ring to rotate. This can prevent the reverse transmission of the semi-synchronous transmission mechanism and the fully synchronous transmission mechanism from causing the locking relationship between the threaded rod and the leveling base to loosen, thereby ensuring the stability of the keel after installation.

[0022] Preferably, a plurality of adjustment holes evenly distributed around the circumference are provided on the outer side of the fastening ring.

[0023] By adopting the above technical solution, when rotating the fastening ring, a straight rod tool such as a screwdriver can be inserted into the adjustment hole, which facilitates the forward or reverse rotation of the fastening ring in a smaller space.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Utilizing the threaded connection between the adjustment sleeve and the threaded rod, when the adjustment sleeve is rotated forward or reverse, the adjustment sleeve can be driven to move away from or towards the wall. The keel is fixed on the connecting seat, and the connecting seat will move synchronously with the adjustment sleeve. The connecting seat can also rotate freely to ensure the connection angle with the keel, thereby achieving the adjustment function of the keel and ensuring that the decorative surface installed on the keel can be flat and orderly.

[0026] 2. The leveling base and the threaded rod are locked and unlocked with the help of the fastening ring and the abutment block. When the fastening ring and the abutment block are respectively against the leveling base and the wall, the threaded rod can be locked to prevent the keel from moving. When adjusting the keel, the fastening ring and the abutment block are separated from the leveling base and the wall respectively. At this time, the threaded rod can slide in the sliding hole with the movement of the keel, which is convenient for follow-up adjustment. It can be fixed after the two ends of the keel are fixed. There is no need to adjust multiple adjustment sleeves simultaneously, which makes the operation simpler and more effective.

[0027] 3. The leveling base is fixed to the wall. During installation, the leveling base can be fixed to the wall by expansion bolts, etc., and the position of the leveling base can be determined first. The two connection points of the leveling base can be rotated along the center to fix it at a position with stronger anchoring force on the wall, which can further improve the fixing effect of the keel and improve stability.

[0039] The following is combined with Figure 1-10 This application is described in further detail.

[0040] The embodiments of the present application disclose an assembled wall stud leveling system.

[0041] Reference Figure 1 、 Figure 2 and Figure 4 A prefabricated wall stud leveling system includes a leveling base 1 fixed to the wall and a threaded rod 4 with a groove 5 on its outer side. The leveling base is N-shaped, with a sliding hole 2 in the middle. The inner wall of the sliding hole 2 is equipped with evenly distributed protrusions 3, which precisely mate with the groove 5 on the outer side of the threaded rod 4 to achieve sliding guidance. A fastening ring 6 is threaded onto the threaded rod 4. When tightened, the fastening ring 6 abuts against the inner side of the leveling base 1. Adjustment holes 48 are also provided on the outer side of the fastening ring 6 to facilitate the operator's use of tools to rotate the fastening ring 6. A fastening block 7 is provided on the end of the threaded rod 4 closest to the wall, which cooperates with the fastening ring 6 to fix the position of the threaded rod 4. An adjusting sleeve 8 is threadedly connected to the outer side of the threaded rod 4, and the end of the adjusting sleeve 8 is rotatably connected to a connecting seat 9, which can flexibly adjust the angle. Finally, the keel 10 is firmly installed through the connecting seat 9. A first mounting hole is provided on the keel 10, and a second mounting hole is provided on the connecting seat 9. The first mounting hole and the second mounting hole are connected by rivets, and the diameter of the rivet is smaller than the inner diameter of the first mounting hole and the second mounting hole, which is convenient for fine-tuning.

[0042] During installation, first determine the installation position of the leveling base 1 based on the wall surface. Using its two pivotable connection points, secure it to a location on the wall with a strong anchoring force. Once the leveling base 1 is secured, rotate the fastening ring 6 forward until it rests against the inside of the leveling base 1. Leveraging the threaded connection, pull the threaded rod 4 toward the wall until the abutment block 7 firmly contacts the wall, locking the threaded rod 4 in place. Once this is complete, connect the connector 9 to the keel 10 to complete the system installation.

[0043] To adjust the keel 10 after installation, when the keel 10 is connected to the multiple connecting bases 9, first reverse the direction of rotation of the fastening rings 6 on the middle leveling bases 1 to separate them from the inner wall of the leveling bases 1. Then, reverse the direction of rotation of the adjustment sleeve 8. Since the adjustment sleeve 8 is connected to the keel 10 via the connecting bases 9 and the ends of the keel 10 are still fixed, the adjustment sleeve 8 can only rotate and cannot move. Reverse rotation of the adjustment sleeve 8 will move the threaded rod 4 toward the adjustment sleeve 8, thereby separating the abutment block 7 from the wall. This releases the fixation between the threaded rod 4 and the leveling base 1, and also releases the fixation in the middle of the keel 10. The keel 10 is now fixed only by the connecting bases 9 at its ends. Next, the operator can rotate the adjustment sleeve 8 on the two leveling bases 1 at both ends of the keel 10 forward or reverse. As the adjustment sleeve 8 rotates forward or reverse, it moves the connecting bases 9 toward or away from the wall, thereby adjusting the keel 10. After determining the position of the keel 10, the adjusting sleeves 8 on the several leveling bases 1 located in the middle of the keel 10 are operated again. At this time, because the two ends of the keel 10 are fixed and the position does not change, the adjusting sleeves 8 are rotated forward to move the threaded rod 4 toward the wall. When the abutting block 7 abuts the wall, the fastening ring 6 is rotated forward to abut the fastening ring 6 against the inner wall of the leveling base 1, and the threaded rod 4 can be locked again with the leveling base 1. During the entire process of adjusting the keel 10, the fastening ring 6 and adjusting sleeve 8 in the middle position and the fastening ring 6 and adjusting sleeve 8 at the two ends can be operated in sequence. There is no need to adjust them simultaneously. This operation method is more convenient.

[0044] refer to Figure 3-Figure 10The adjusting sleeve 8 has a circular hole 11 in the middle thereof which is coaxial with the adjusting sleeve 8, and a long hole 12 in the middle thereof which is also coaxial with the circular hole 11. A rotating rod 13 is rotatably arranged in the long hole 12, and its end is fixedly connected to the clamping block 7. The outer side of the clamping block 7 has a polygonal cylindrical structure, and the inner side of the fastening ring 6 has a polygonal inner groove 14 which completely matches its outer shape, and the clamping block 7 can slide in the polygonal inner groove 14. A semi-synchronous transmission mechanism and a fully synchronous transmission mechanism are arranged between the end of the rotating rod 13 away from the clamping block 7 and the adjusting sleeve 8. At the same time, a damping structure is also arranged between the adjusting sleeve 8 and the connecting seat 9.

[0045] When the keel 10 needs to be released from its central position, the operator rotates the fastening ring 6 in the opposite direction. Since the polygonal inner groove 14 on the inner side of the fastening ring 6 matches the polygonal cylindrical structure of the abutment block 7, the fastening ring 6 will simultaneously drive the abutment block 7 to rotate in the opposite direction. Since the abutment block 7 is fixed to the end of the rotating rod 13, the abutment block 7 will further drive the rotating rod 13 to rotate in the opposite direction.

[0046] At this moment, the semi-synchronous transmission mechanism provided between the rotating rod 13 and the regulating sleeve 8 comes into play. Through the transmission of the semi-synchronous transmission mechanism, the reverse rotation number of the regulating sleeve 8 is half the number of reverse rotations of the rotating rod 13.

[0047] During this half of the travel, when the rotating rod 13 and the adjusting sleeve 8 rotate synchronously in opposite directions, the adjusting sleeve 8 cannot move because it is connected to the keel 10 via the connecting seat 9, and the ends of the keel 10 are fixed. Since the adjusting sleeve 8 cannot move, the fastening ring 6 also cannot move. In this case, the threaded rod 4 and the abutment block 7 move away from the wall.

[0048] At rotating rod 13, continue to rotate in the opposite direction, and in the other half stroke that adjusting sleeve 8 does not rotate, equally because adjusting sleeve 8 cannot move, threaded rod 4 also remains motionless. At this moment, only fastening ring 6 moves to the direction near the wall surface.

[0049] When the entire stroke is completed, the fastening ring 6 moves away from the leveling base 1 and the abutting block 7 moves away from the wall, thus releasing the fixation between the threaded rod 4 and the leveling base 1, and the fixation of the middle position of the keel 10 is also released. During this process, the operator only needs to rotate the fastening ring 6 in the opposite direction, without having to rotate the fastening ring 6 and the adjustment sleeve 8 separately, nor to adjust the stroke difference between the two, making the operation more convenient.

[0050] After the operator has adjusted the position of the keel 10, the threaded rod 4 needs to be locked with the leveling base 1 again. At this point, the operator only needs to rotate the fastening ring 6 in the forward direction. Due to the cooperation between the fastening ring 6 and the abutment block 7, the fastening ring 6 will drive the abutment block 7 to rotate in the forward direction, and the abutment block 7 will drive the rotating rod 13 to rotate in the forward direction.

[0051] At this point, the fully synchronous transmission mechanism between the rotating rod 13 and the adjusting sleeve 8 begins to operate. Driven by this fully synchronous transmission mechanism, the rotating rod 13 and the adjusting sleeve 8 first rotate in sync with the fastening ring 6 in the forward direction. During this synchronous rotation, the threaded rod 4 moves toward the wall until the abutment block 7 contacts the wall.

[0052] When the abutment block 7 contacts the wall, the fully synchronous transmission mechanism stops. At this point, the fastening ring 6 continues to rotate forward, while the threaded rod 4 remains stationary. The fastening ring 6 then moves toward the leveling base 1, eventually contacting it. This locks the threaded rod 4 with the leveling base 1 again. During this locking process, the operator only needs to rotate the fastening ring 6 forward. There is no need to rotate the adjustment sleeve 8 and the fastening ring 6 separately, nor is there any need to consider the number of rotations required, making operation much simpler.

[0053] refer to Figure 5 The damping structure between the adjustment sleeve 8 and the connecting seat 9 primarily consists of a damping rubber ring 15. Specifically, an insert groove is provided on the end surface of the adjustment sleeve 8 near the connecting seat 9. The damping rubber ring 15 is secured within this insert groove, with the side of the damping rubber ring 15 facing away from the insert groove tightly abutting against the connecting seat 9. This structural arrangement allows the damping rubber ring 15 to fully exert its damping effect, providing a certain resistance during the relative motion between the adjustment sleeve 8 and the connecting seat 9, thereby increasing the stability and controllability of the adjustment process.

[0054] Under the action of the damping rubber ring 15, the rotation between the adjusting sleeve 8 and the connecting seat 9 has a certain friction force. When the rotational force is less than the friction force, the adjusting sleeve 8 and the connecting seat 9 will maintain synchronous rotation or relative stillness.

[0055] refer to Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 10The semi-synchronous transmission mechanism primarily consists of a first telescopic tongue 17. A first mounting groove 16 for mounting the first telescopic tongue 17 is provided on the outer side of the rotating rod 13. The first telescopic tongue 17 is able to slide within the first mounting groove 16. To prevent the first telescopic tongue 17 from falling out of the first mounting groove 16, first stoppers 18 are provided on both sides. Furthermore, a first elastic member 19 is installed at the bottom of the first mounting groove 16 to push the first telescopic tongue 17 outward. This allows the first telescopic tongue 17 to extend outward under the elastic force of the first elastic member 19 when no external force is applied. Furthermore, a first chamfer 20 is specifically provided on the outer side of the first telescopic tongue 17.

[0056] Two symmetrically spaced extension blocks 40 are located inside the circular hole 11 of the adjustment sleeve 8. A fixing bar 21 with a boss 22 is secured to the inside of the connecting base 9. As the rotating rod 13 rotates, the outwardly extending first telescopic tongue 17 contacts the boss 22 on the fixing bar 21. With the boss 22 blocking the first telescopic tongue 17, it overcomes the elastic force of the first elastic member 19 and retracts into the first mounting slot 16.

[0057] When the operator rotates the fastening ring 6 in the reverse direction, the polygonal inner groove 14 on the inner side of the fastening ring 6 tightly fits the polygonal column structure of the abutment block 7, causing the abutment block 7 to rotate in the reverse direction synchronously. In addition, because the abutment block 7 is fixed to the end of the rotating rod 13, the rotating rod 13 also rotates in the reverse direction together with the abutment block 7.

[0058] During the rotation of the rotating rod 13, the first retractable tongue 17, mounted in the first mounting slot 16 on its outer side, extends under the action of the first elastic member 19. When the first retractable tongue 17 rotates to contact the extension block 40 symmetrically located inside the circular hole 11 of the adjustment sleeve 8, it abuts against one side of the extension block 40. At this point, the first retractable tongue 17 generates a thrust on the extension block 40, thereby driving the adjustment sleeve 8 to rotate in the opposite direction.

[0059] As the rotating rod 13 continues to rotate, when the first telescopic tongue 17 rotates to the position of the boss 22 on the fixing bar 21 inside the connecting seat 9, the first telescopic tongue 17 overcomes the elastic force of the first elastic member 19 due to the obstruction of the boss 22 and retracts into the first mounting groove 16. After the first telescopic tongue 17 retracts, it separates from the extension block 40 and no longer exerts a thrust on the extension block 40, so the adjustment sleeve 8 stops rotating.

[0060] After the first retractable tongue 17 passes over the boss 22, it extends outward again under the elastic force of the first elastic member 19. The rotating rod 13 then continues to rotate in the opposite direction. After the first retractable tongue 17 rotates half a turn, it abuts against the other extension block 40. At this point, the first retractable tongue 17 can again exert a thrust on the extension block 40, driving the adjustment sleeve 8 to rotate in the opposite direction another half turn.

[0061] This cycle repeats itself. During the entire rotation process, each time the rotating rod 13 completes one circle of reverse rotation, the adjustment sleeve 8 can be driven to rotate half a circle in the reverse direction through the interaction between the first telescopic tongue 17, the extension block 40, and the boss 22, thereby achieving a specific semi-synchronous transmission effect between the rotating rod 13 and the adjustment sleeve 8.

[0062] refer to Figure 7-10 The fully synchronous transmission mechanism is composed of multiple components, the key component being several second telescopic tongues 24. Several equally spaced second mounting slots 23 are provided on the outside of the rotating rod 13, each of which slides a second telescopic tongue 24. To prevent the second telescopic tongue 24 from falling out of the second mounting slot 23, second stoppers 25 are provided on both sides of the second telescopic tongue 24. Furthermore, a second elastic member 26 for pushing the second telescopic tongue 24 outward is installed at the bottom of the second mounting slot 23, allowing the second telescopic tongue 24 to extend outward under the elastic force of the second elastic member 26 when no external force is applied. Furthermore, a second chamfer 27 is provided on one side of the exterior of the second telescopic tongue 24, and the second chamfer 27 is oriented in the opposite direction to the first chamfer 20 on the first telescopic tongue 17.

[0063] On the inner side of the rotating rod 13, there is a socket 28, in which a rod 29 is slidably inserted. The rod 29 passes through the pressing block 7, and an extrusion plate 30 with the same shape as the pressing block 7 is fixed at the end of the rod 29. At the bottom of the second mounting groove 23, there is an inner hole 31, in which a slider 32 is slidably set. One end of the slider 32 is fixedly connected to the second elastic member 26, and the other end is fixed with a triangular block 33. At the same time, on the outer side of the rod 29, there are a number of slots 34 evenly distributed around the circumference. A triangular groove 35 is provided on the side wall of the slot 34 close to the pressing block 7. The shape of the triangular groove 35 matches that of the triangular block 33, which can realize the engagement and separation of the two.

[0064] When the operator rotates the fastening ring 6 in the forward direction, the fully synchronized transmission mechanism begins to function. During this rotation, one of the second retractable tongues 24 on the outside of the rotating rod 13, under the action of the second elastic member 26, presses against the side of an extension block 40 inside the circular hole 11. This contact allows the second retractable tongue 24 to drive the adjustment sleeve 8 in forward rotation.

[0065] When the second retractable tongue 24, which is driving the adjusting sleeve 8 to rotate, reaches the boss 22, it is blocked by the boss 22. The second retractable tongue 24 overcomes the elastic force of the second elastic member 26 and retracts into the second mounting groove 23, thereby passing over the boss 22. After passing over the boss 22, the second retractable tongue 24 disengages from the extension block 40 and temporarily stops applying thrust to the adjusting sleeve 8.

[0066] However, as the rotating rod 13 continues to rotate forward by a smaller angle, the second telescopic tongue 24 on the outer side of the rotating rod 13 will quickly abut against the other extension block 40, continuing to drive the adjustment sleeve 8 to rotate forward. In this way, in most cases, the rotating rod 13 and the adjustment sleeve 8 can basically achieve synchronous forward rotation.

[0067] After the rotating rod 13 and the adjustment sleeve 8 rotate synchronously forward for a certain distance, the extrusion plate 30 at the end of the insertion rod 29 will contact the wall. At this time, the threaded rod 4 and the rotating rod 13 will continue to move toward the wall. Because the triangular groove 35 matches the triangular block 33 at the end of the slider 32, the triangular groove 35 will hook the triangular block 33 as the rotating rod 13 moves. Then, as the rotating rod 13 continues to move, the triangular groove 35 will pull the triangular block 33, which in turn pulls the second elastic member 26 toward the bottom of the second mounting slot 23, causing the second telescopic tongue 24 to gradually retract into the second mounting slot 23.

[0068] When the abutting block 7 moves to abut against the extrusion plate 30, the second telescopic tongue 24 has contracted to a certain extent and will then separate from the extension block 40. Thereafter, while the fastening ring 6 continues to drive the rotating rod 13 to rotate forward and eventually abut against the inner side of the leveling base 1, the adjusting sleeve 8 stops rotating.

[0069] Even after the adjustment sleeve 8 stops rotating, the first telescopic tongue 17 in the first mounting groove 16 outside the rotating rod 13 abuts against the extension block 40. Since the damping rubber ring 15 provided between the adjustment sleeve 8 and the connecting seat 9 generates rotation resistance, the first telescopic tongue 17 will shrink into the first mounting groove 16 and pass over the extension block 40 under the action of the first chamfer 20 provided on one side of the outer side.

[0070] Similarly, during the reverse rotation of the rotating rod 13, when the rotating rod 13 is in the half-turn in which the adjusting sleeve 8 does not rotate but the rotating rod 13 rotates in the reverse direction, even if the second telescopic tongue 24 on the outer side of the rotating rod 13 abuts against the extension block 40, due to the rotation resistance brought to the adjusting sleeve 8 by the damping rubber ring 15, the second telescopic tongue 24 will also be acted upon by the second chamfer 27 on one side of the outer side thereof, and will retract into the second mounting groove 23 and pass over the extension block 40.

[0071] Through such design and working mode, the semi-synchronous transmission mechanism and the fully synchronous transmission mechanism will not interfere with each other during the operation of the entire system, and can function independently and stably.

[0072] The first elastic member 19 and the second elastic member 26 are both elastic metal sheets, and the middle position of the elastic metal sheet is respectively against the first telescopic tongue 17 and the second telescopic tongue 24, and the two ends of the elastic metal sheet are respectively against the bottom of the first mounting groove 16 and the second mounting groove 23. The elastic metal sheet can not only provide elastic force but also occupy less space.

[0073] refer to Figure 7 On the side of the pressing block 7 near the extrusion plate 30, a number of guide holes 36 are provided. At the same time, a number of guide rods 37 are fixedly mounted on the extrusion plate 30. These guide rods 37 can be precisely slidably inserted into the guide holes 36. The cooperation between the guide holes 36 and the guide rods 37 provides guidance for the relative movement between the extrusion plate 30 and the pressing block 7. In addition, a spring slot 38 is specially provided at the center position of the side of the pressing block 7 near the extrusion plate 30. A support spring 39 is installed in the spring slot 38. The two ends of the support spring 39 respectively abut against the extrusion plate 30 and the bottom of the spring slot 38. The elastic action of the support spring 39 provides a buffer and support force between the extrusion plate 30 and the pressing block 7, ensuring the stability and reliability of the two during relative movement.

[0074] When the extrusion plate 30 is in contact with the wall, as the abutment block 7 moves toward or away from the wall, the guide holes 36 on the abutment block 7 cooperate with the guide rods 37 on the extrusion plate 30 to provide precise guidance for their relative sliding. This structural design effectively ensures smooth sliding between the extrusion plate 30 and the abutment block 7, preventing the slider 32 in the fully synchronous transmission mechanism from getting stuck due to poor movement.

[0075] At the same time, the support spring 39 installed in the spring slot 38 on the side of the abutment block 7 plays an important role. When the abutment block 7 moves away from the wall, the support spring 39 releases its elastic potential energy and, through its own supporting force, automatically separates the extrusion plate 30 from the abutment block 7. During this process of separation of the extrusion plate 30 from the abutment block 7, the triangular slot 35 on the insertion rod 29 and the triangular block 33 at the end of the slider 32 also disengage, further reducing the risk of the fully synchronous transmission mechanism getting stuck and significantly improving the smoothness and reliability of the leveling system during use.

[0076] refer to Figure 5 and Figure 6Inside the circular hole 11 of the adjustment sleeve 8, two receiving slots 41 are provided for accommodating the extension block 40, which can slide within the receiving slots 41. A connecting hole is defined at the bottom of the receiving slots 41, extending through the adjustment sleeve 8 and outward. A pull rod 42 slides within the connecting hole. One end of the pull rod 42 is fixedly connected to the extension block 40, while the other end extends outside the adjustment sleeve 8 and is fixedly connected to a support rod 43.

[0077] Furthermore, two symmetrically distributed connecting ears 44 are fixed to the outer wall of the adjustment sleeve 8. Each connecting ear 44 is rotatably mounted with a rotating shaft 45, one end of which is fixedly connected to a handle 47 for easy operation by the operator. The other end of the rotating shaft 45 has an arcuate groove 46 extending from the edge to the center. The end of the support rod 43 is precisely inserted into this arcuate groove 46, forming a linkage structure between the handle 47, the rotating shaft 45, the support rod 43, and the extension block 40.

[0078] When adjusting the ends of the keel 10 or installing it for the first time, if it is necessary to rotate the adjustment sleeve 8 forward or reverse while the threaded rod 4 is locked with the leveling base 1, the two handles 47 on the adjustment sleeve 8 can be first extended to the sides. As the handles 47 are extended, the shaft 45 on the connecting ear 44 rotates accordingly. The arc-shaped groove 46 on the end surface of the shaft 45, through the mating support rod 43, pulls the pull rod 42 in the connecting hole toward the outside of the adjustment sleeve 8. As the pull rod 42 moves outward, the extension block 40 originally located inside the circular hole 11 is pulled into the receiving groove 41.

[0079] At this point, the operator can rotate the adjustment sleeve 8 forward or backward by gripping the two handles 47. Because the extension block 40 has retracted into the receiving slot 41 and no longer contacts the first and second retractable tongues 17 and 24 on the rotating rod 13, rotating the adjustment sleeve 8 does not cause the rotating rod 13 to rotate, and thus does not cause the fastening ring 6 to rotate. This operating method effectively prevents reverse transmission of the semi-synchronous and fully synchronous transmission mechanisms, prevents the locking relationship between the threaded rod 4 and the leveling base 1 from loosening due to accidental transmission, and effectively ensures the stability of the installed keel 10.

[0080] The present embodiment of the present invention employs a prefabricated wall keel leveling system that utilizes the threaded connection between the adjustment sleeve 8 and the threaded rod 4. When the adjustment sleeve 8 is rotated forward or backward, the adjustment sleeve 8 moves away from or toward the wall accordingly, driving the connecting seat 9 to move. This adjusts the keel 10 and ensures a smooth and even decorative surface mounted on the keel 10. Simultaneously, the system utilizes a fastening ring 6 and abutment block 7 to lock and unlock the leveling base 1 and the threaded rod 4. When the fastening ring 6 abuts the leveling base 1 and the abutment block 7 abuts the wall, the threaded rod 4 is locked, preventing the keel 10 from moving. To adjust the keel 10, the fastening ring 6 and abutment block 7 are separated from the leveling base 1 and the wall, respectively. This allows the threaded rod 4 to slide within the sliding hole 2 as the keel 10 moves, facilitating flexible adjustment. Furthermore, the keel 10 can be secured at both ends before any other fixing operations are performed, eliminating the need to adjust multiple adjustment sleeves 8 simultaneously, making operation simpler and more efficient.

[0081] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
