[0016] In summary, the present application includes at least one of the following beneficial technical effects: The present application takes into account that since workers need to drill hanging holes on the ceiling, drilling deviations are likely to occur, resulting in the suspension rod on the ceiling not matching the holes, and in this case the installation cannot be performed. Therefore, a lateral adjustment mechanism is provided, so that when the hanging hole and the suspension rod do not match, the two pulling blocks can be pulled separately to drive the pin rod to leave the pin hole. At this time, the first guide block is not restricted, and the suspension rod and the first guide block can be pushed along the trajectory of the first guide groove for lateral adjustment. After moving to the appropriate position, the pulling block is released, and the tension generated by the tension spring will drive the pulling block and the pin rod to reset, so that the pin rod enters the corresponding pin hole, and the first guide block is restricted again to complete the lateral adjustment of the suspension rod position.

[0017] The present application takes into account that there may be longitudinal deviations in the punching position during the operation of the workers. Therefore, a longitudinal adjustment mechanism is set up, which can move the two threaded rods on both sides of the second guide block upward by twisting the two threaded rods, and at the same time drive the traction block and the limit rod to move upward. When the limit rod leaves the inside of the limit hole, it can drive the second guide block, support beam, suspension rod and other structures to move longitudinally. After reaching the appropriate position, the threaded rod can be moved downward by twisting the threaded rod in the opposite direction, and at the same time drive the traction block and the limit rod to move downward and enter the corresponding limit hole to complete the longitudinal adjustment of the suspension rod.

[0018] The present application takes into account that during adjustment, if the distance between the position of the suspension rod and the position of the suspension hole is too large, it will cause deviation in the adjustment. Therefore, by setting up a stabilizing mechanism, the keel can be raised to a position close to the ceiling, and then the lever is held and rotated, thereby driving the twisting block, the twisting rod and the first bevel gear to rotate around the second bearing, the first bevel gear will drive the second bevel gear to rotate, and the second bevel gear will drive the screw rod to rotate around the third bearing. While the screw rod is rotating, the moving block and the sliding block will move along the trajectory of the sliding groove, and the moving block will drive the stabilizing rod, the stabilizing plate and other structures to approach the wall beside the keel until the stabilizing plate is in close contact with the wall, and the friction block on the surface of the stabilizing plate is in close contact with the wall, achieving the role of limiting, and entering the limit position of the keel. After that, the workers can adjust the suspension rod more conveniently.

[0019] The present application takes into account that the shapes of walls are different and there may be some potholes. At this time, the stabilizing plate is in close contact with the potholes and cannot limit the keel. Therefore, a fine-tuning mechanism is provided to enable the hand screw to leave the inside of the adjustment hole by turning the hand screw. After that, the position of the transmission block, the stabilizing plate and the friction block can be adjusted along the position of the adjustment groove, thereby effectively preventing the stabilizing plate from contacting the potholes of the wall.

[0020] The lateral adjustment mechanism and the longitudinal adjustment mechanism in the present application can adjust the position of the hanger rod laterally and longitudinally, making it easier to install. At the same time, the stabilizing mechanism can adjust structures such as the keel and the hanger rod to a position close to the ceiling, and limit them so that the hanger rod is close to the position of the hanging hole, which is beneficial to the accuracy of adjustment. Considering the different shapes of the walls, there may be some potholes. At this time, the stabilizing plate is in close contact with the potholes and cannot limit the keel. Therefore, by setting a fine-tuning mechanism, the position of the stabilizing plate and the friction block can be adjusted to effectively avoid contact between the stabilizing plate and the potholes in the wall. This solves the problem that during manual operation, workers need to drill hanging holes on the ceiling, which is prone to drilling deviations, making the hanger rod on the ceiling mismatched with it. In this case, it cannot be installed and needs to be re-drilled for installation. The connection positions of most existing hangers and keels are also fixed, which affects the normal installation of the ceiling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] See also Figure 1-Figure 11 , the present application provides a technical solution for a building ceiling.

[0035] Embodiment 1: A building ceiling comprises a decorative panel 1, a keel 2 and a plurality of hangers 3, wherein the keel 2 is fixedly mounted on the top of the decorative panel 1, the hanger 3 is located at the top of the keel 2, the top of the keel 2 is slidably connected to two support beams 4, a first guide groove 5 is provided on one side of the support beam 4, a plurality of first guide blocks 6 are slidably connected inside the first guide groove 5, and the top of the first guide block 6 is fixedly connected to the bottom of the hanger 3; a transverse adjustment mechanism, which is fixedly arranged on the first guide block 6 and can adjust the position of the hanger 3 laterally; a longitudinal adjustment mechanism, which is fixedly arranged on the support beam 4 and can adjust the longitudinal position of the hanger 3; a stabilizing mechanism, which is fixedly arranged on the keel 2 and can limit the position of the keel 2 through the stabilizing mechanism to improve the stability of the keel 2.

[0036] One implementation of the present embodiment is: the lateral adjustment mechanism includes support blocks 7 fixedly arranged on both sides of the first guide block 6, the top of the support block 7 is fixedly connected to one side of the first guide block 6, a pulling block 8 is arranged on one side of the first guide block 6, a pin rod 9 is fixedly connected to one side of the pulling block 8, one end of the pin rod 9 passes through one side of the support block 7, and a plurality of pin holes 10 for use with the pin rod 9 are horizontally opened on both sides of the support beam 4.

[0037] In this embodiment, it is taken into consideration that since workers need to drill holes for hanging on the ceiling, drilling deviations may easily occur, resulting in a mismatch between the hanging rod 3 on the ceiling and the hanging rod 3. In this case, the hanging rod 3 cannot be installed. Therefore, a lateral adjustment mechanism is provided, so that when the hanging hole and the hanging rod 3 do not match, the two pulling blocks 8 can be pulled separately to drive the pin rod 9 to leave the pin hole 10. At this time, the first guide block 6 is not restricted. At this time, the hanging rod 3 and the first guide block 6 can be pushed along the trajectory of the first guide groove 5 for lateral adjustment. After moving to the appropriate position, by loosening the pulling block 8, the tension generated by the tension spring 43 will drive the pulling block 8 and the pin rod 9 to reset, so that the pin rod 9 enters the corresponding pin hole 10, and restricts the first guide block 6 again, completing the lateral adjustment of the position of the hanging rod 3.

[0038] The problem that workers need to drill holes on the ceiling, which may lead to drilling deviation, makes the hanging rod 3 on the ceiling mismatched, and the installation cannot be performed in this case is solved.

[0039] Preferably, a tension spring 43 is sleeved on the surface of the pin rod 9 , one end of the tension spring 43 is fixedly connected to one side of the support block 7 , and the other end of the tension spring 43 is fixedly connected to one side of the pulling block 8 .

[0040] In this embodiment, a tension spring 43 is provided, and the tension generated by the tension spring 43 can drive the pulling block 8 and the pin rod 9 to reset, so that the pin rod 9 can accurately enter the pin hole 10, thereby playing a role of reset.

[0041] Embodiment 2: On the basis of embodiment 1, the lateral adjustment mechanism in this embodiment can adjust the position of the suspension rod 3 laterally so that the position of the suspension rod 3 is consistent with the suspension hole. However, considering that there will be longitudinal deviation in the drilling position during the operation of the workers, the longitudinal adjustment mechanism in this application includes four second guide blocks 11 fixedly connected to the bottom of the support beam 4, and a second guide groove 12 used in conjunction with the second guide block 11 is provided on one side of the keel 2. Two connecting rods 13 are fixedly connected to the top of the second guide block 11, and a connecting block 14 is fixedly connected to the top of the connecting rod 13. A threaded rod 15 is threadedly connected to the top of the connecting block 14, and a first bearing 16 is provided at the bottom of the threaded rod 15. The bottom of the threaded rod 15 passes through the bottom of the connecting block 14 and is rotatably connected to a traction block 17 through the first bearing 16. A limiting block 18 is fixedly connected to one side of the traction block 17, and two limiting rods 19 are fixedly connected to the bottom of the limiting block 18. A plurality of limiting holes 20 used in conjunction with the limiting rod 19 are longitudinally provided on the top of the keel 2.

[0042] In this embodiment, it is taken into consideration that there may be longitudinal deviations in the punching positions during the operation of the workers. Therefore, a longitudinal adjustment mechanism is provided, and the two threaded rods 15 on both sides of the second guide block 11 can be turned, so that the threaded rods 15 can move upward, and at the same time drive the traction block 17 and the limit rod 19 to move upward. When the limit rod 19 leaves the inside of the limit hole 20, the second guide block 11, the support beam 4, the suspension rod 3 and other structures can be driven to move longitudinally. After reaching the appropriate position, the threaded rod 15 can be turned in the opposite direction to move the threaded rod 15 downward, and at the same time drive the traction block 17 and the limit rod 19 to move downward and enter the corresponding limit hole 20, thereby completing the longitudinal adjustment of the suspension rod 3. The problem that there may be longitudinal deviations in the punching positions during the operation of the workers is solved.

[0043] Embodiment 3: On the basis of embodiment 2, the lateral adjustment mechanism and the longitudinal adjustment mechanism in this embodiment can adjust the lateral position and the longitudinal position of the suspension rod 3. However, considering that during adjustment, if the distance between the position of the suspension rod 3 and the position of the suspension hole is too large, it will cause deviation in the adjustment. The stabilizing mechanism in this application includes four stabilizing blocks 21 fixedly connected to both sides of the keel 2, and a transmission groove 22 is opened inside the stabilizing block 21. A first bevel gear 23 is arranged inside the transmission groove 22. A twisting rod 24 is fixedly connected to the top of the first bevel gear 23. The top of the twisting rod 24 passes through the outside of the stabilizing block 21 and is fixedly connected to the twisting block 25. One side of the first bevel gear 23 is meshedly connected to the second bevel gear 26. One side of the second bevel gear 26 is fixedly connected to a screw rod 27. The surface of the screw rod 27 is transmission-connected to a moving block 28. One side of the moving block 28 is fixedly connected to two stabilizing rods 29. One side of the moving block 28 is fixedly connected to two stabilizing rods 29. One side of the stabilizing block 21 is provided with two stabilizing plates 30.

[0044] In this embodiment, it is taken into consideration that during adjustment, if the distance between the position of the suspension rod 3 and the position of the suspension hole is too large, it will cause deviation in the adjustment. Therefore, by setting a stabilizing mechanism, the keel 2 can be raised to a position close to the ceiling, and then the lever 41 can be held and rotated, thereby driving the twisting block 25, the twisting rod 24 and the first bevel gear 23 to rotate around the second bearing 37, the first bevel gear 23 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 will drive the screw rod 27 to rotate around the third bearing 38. While the screw rod 27 rotates, the moving block 28 and the sliding block 39 will move along the trajectory of the sliding groove 40, and the moving block 28 will drive the stabilizing rod 29, the stabilizing plate 30 and other structures to approach the wall on the side of the keel 2 until the stabilizing plate 30 is in close contact with the wall, and the friction block 36 on the surface of the stabilizing plate 30 will be in close contact with the wall, achieving the role of limiting, and entering the limit position of the keel 2, after which the worker can adjust the suspension rod 3 more conveniently.

[0045] The problem that a deviation may occur in the adjustment if the distance between the position of the suspension rod 3 and the position of the suspension hole is too large during the adjustment is solved.

[0046] Preferably, a second bearing 37 is provided at the bottom of the first bevel gear 23, and the bottom of the first bevel gear 23 is rotatably connected to the inner wall of the transmission groove 22 through the second bearing 37. A third bearing 38 is provided at one end of the screw rod 27, and is rotatably connected to the inner wall of the transmission groove 22 through the third bearing 38.

[0047] In this embodiment, the second bearing 37 and the third bearing 38 are provided to support and limit the first bevel gear 23, the second bevel gear 26 and the screw rod 27, so that the first bevel gear 23 and the second bevel gear 26 are always kept in meshing state, and at the same time, it can ensure that the rotation process is smoother.

[0048] Preferably, a sliding block 39 is fixedly connected to the bottom of the moving block 28 , and a sliding groove 40 for use with the sliding block 39 is formed on the inner wall of the transmission groove 22 .

[0049] In this embodiment, by providing the sliding block 39 and the sliding groove 40 , when the screw rod 27 rotates to transmit the moving block 28 , the moving block 28 can be restricted so that it can only move along the trajectory of the sliding groove 40 together with the sliding block 39 .

[0050] Preferably, two sides of the twisting block 25 are fixedly connected with lever rods 41 , and the surfaces of the lever rods 41 are covered with anti-slip pads 42 .

[0051] In this embodiment, by providing the lever rod 41 and the anti-skid pad 42, a lever point can be provided for the worker to rotate the twisting block 25. At the same time, the anti-skid pad 42 can improve the comfort during the rotation process and play an anti-skid role.

[0052] Preferably, a friction block 36 is fixedly connected to one side of the stabilizing plate 30 to increase the friction force when the stabilizing plate 30 contacts the wall.

[0053] In this embodiment, by providing the friction block 36 , the friction force when the stabilizing plate 30 contacts the wall surface can be increased, thereby preventing the keel 2 from sliding down due to the gravity, thereby preventing the keel 2 from being unable to limit the position.

[0054] Embodiment 4: On the basis of embodiment 3, the stabilizing mechanism in this embodiment can lift the keel 2 to a position close to the ceiling, and then position the keel 2 with the wall as a support point in cooperation with the stabilizing mechanism, so as to facilitate workers to adjust the position of the suspension rod 3. However, considering the different shapes of the walls, there may be some potholes. At this time, the stabilizing plate 30 is in close contact with the potholes and cannot limit the keel 2. In this application, a fine-tuning mechanism is provided on one side of the stabilizing block 21, which can adjust the contact position of the stabilizing plate 30 with the wall to improve the stabilizing effect.

[0055] The fine-tuning mechanism includes an adjustment block 31 arranged on one side of the stabilizing block 21, one end of the stabilizing rod 29 penetrates through one side of the stabilizing block 21 and is fixedly connected to one side of the adjustment block 31, one side of the adjustment block 31 is provided with two adjustment grooves 32, the interior of the adjustment groove 32 is slidably connected with a transmission block 33, one side of the transmission block 33 is fixedly connected to one side of the adjustment block 31, the top of the transmission block 33 is threadedly connected with a hand screw 34, and the top of the adjustment block 31 is provided with a plurality of adjustment holes 35 used in conjunction with the hand screw 34.

[0056] In this embodiment, it is taken into account that the shapes of the walls are different and there may be some potholes. At this time, the stabilizing plate 30 is in close contact with the potholes and cannot limit the keel 2. Therefore, by providing a fine-tuning mechanism, the hand screw 34 can be turned to make the hand screw 34 leave the inside of the adjustment hole 35. After that, the positions of the transmission block 33, the stabilizing plate 30 and the friction block 36 can be adjusted along the position of the adjustment slot 32, effectively avoiding contact between the stabilizing plate 30 and the potholes in the wall.

[0057] The problem that there may be some potholes due to the different shapes of the wall and the stabilizing plate 30 is in close contact with the potholes and cannot limit the keel 2 is solved.

[0058] Working principle: First, turn the hand screw 34 to make it leave the inside of the adjustment hole 35, and then adjust the position of the transmission block 33, the stabilizing plate 30 and the friction block 36 along the position of the adjustment slot 32 to avoid contact between the stabilizing plate 30 and the potholes on the wall.

[0059] Then, the keel 2 is raised to a position close to the ceiling, and then the lever 41 is held and rotated, thereby driving the twisting block 25, the twisting rod 24 and the first bevel gear 23 to rotate around the second bearing 37, and the first bevel gear 23 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 will drive the screw rod 27 to rotate around the third bearing 38. When the screw rod 27 rotates, the moving block 28 and the sliding block 39 will move along the trajectory of the sliding groove 40, and the moving block 28 will drive the stabilizing rod 29, the stabilizing plate 30 and other structures to approach the wall on the side of the keel 2 until the stabilizing plate 30 is in close contact with the wall, and the friction block 36 on the surface of the stabilizing plate 30 is in close contact with the wall, thereby achieving the role of limiting.

[0060] When the hanging hole and the hanging rod 3 do not match, by pulling the two pulling blocks 8 respectively, the pin rod 9 is driven to leave the pin hole 10. At this time, the first guide block 6 is no longer restricted. At this time, the hanging rod 3 and the first guide block 6 can be pushed to perform lateral adjustment along the trajectory of the first guide groove 5. When moved to the appropriate position, by loosening the pulling block 8, the tension generated by the tension spring 43 will drive the pulling block 8 and the pin rod 9 to reset, so that the pin rod 9 enters the corresponding pin hole 10, and restricts the first guide block 6 again, completing the lateral adjustment of the position of the hanging rod 3.

[0061] Afterwards, by twisting the two threaded rods 15 on both sides of the second guide block 11, the threaded rod 15 will move upward, and at the same time drive the traction block 17 and the limit rod 19 to move upward. When the limit rod 19 leaves the inside of the limit hole 20, it can drive the second guide block 11, the support beam 4 and the suspension rod 3 and other structures to move longitudinally. After reaching the appropriate position, twisting the threaded rod 15 in the opposite direction can make the threaded rod 15 move downward, and at the same time drive the traction block 17 and the limit rod 19 to move downward and enter the corresponding limit hole 20 to complete the longitudinal adjustment of the suspension rod 3.

[0062] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
