Description

Technical Field

[0001] This utility model relates to the field of mounting brackets, and in particular to a ceiling mounting bracket. Background Technology

[0002] A suspended ceiling is a decorative and functional structure on the interior ceiling of a building, typically composed of a frame and decorative panels. It not only conceals roof pipes and structural defects but also beautifies the space through its design. The mounting bracket is the core component that supports the installation of the suspended ceiling structure. It is mostly made of metal and is used to fix the entire suspended ceiling to the building's roof or walls. The main functions of the ceiling mounting bracket are to accurately support the weight of the ceiling decorative panels, ensuring that the ceiling can be installed and fixed stably. At the same time, the height of the bracket can be adjusted to control the raising and lowering of the decorative panels, adapting to different roof heights and construction needs, and providing a basic guarantee for the safety of the suspended ceiling. Ceiling mounting brackets provide a stable support for ceiling decorative panels. Through a pre-set support structure, the decorative panels can be quickly supported, avoiding panel shifting and damage caused by lack of support during installation. At the same time, they can precisely control the splicing gaps and flatness between decorative panels, reducing construction difficulty and improving installation efficiency. They are mainly used in various indoor spaces that require the installation of ceiling decorative panels, such as living rooms and bedrooms in residential homes, and shops and restaurants in commercial spaces. In existing technologies, some ceiling mounting brackets are difficult to self-lock after being raised due to external factors such as vibration, which significantly increases the difficulty of operation. Workers need to use additional tools to repeatedly adjust the height to calibrate the flatness of the ceiling. This not only consumes a lot of time and reduces construction efficiency, but also easily leads to uneven gaps in the splicing of decorative panels and uneven overall ceiling height due to the adjustment accuracy, affecting the aesthetics. Therefore, a ceiling mounting bracket is proposed to solve the above problems. Utility Model Content

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0010] Reference Figures 1 to 3This utility model provides an embodiment of a ceiling mounting bracket, including a base 1, which serves as the basic load-bearing component of the entire bracket, used to stably support all structures above, ensuring the stability of the bracket when placed, and preventing tilting due to uneven force. The bottom of the base 1 is fixedly connected to multiple casters 2, which can realize the flexible movement of the bracket on the ground, making it convenient to adjust the placement of the bracket according to the needs of the ceiling installation location, eliminating the need for manual handling of the entire bracket, greatly saving labor costs and adjustment time. At the same time, a locking structure is provided to prevent movement during operation. The top of the base 1 is fixedly connected to a support column 3, which serves as the main vertical support structure. An internal cavity is reserved to accommodate components and to provide vertical sliding guides for subsequent components, ensuring the verticality and stability of the structure during lifting. The support column 3 is provided with a lifting mechanism 4, which is used to realize the height adjustment of the bracket to adapt to the installation needs of ceilings with different heights. The rotational motion is converted into linear lifting motion through mechanical transmission. The top of the lifting mechanism 4 is provided with a support mechanism 5, which is used to support decorative panels and can flexibly adjust the horizontal span according to the width of the ceiling. It also has a folding function to reduce the space occupation when not in use. The lifting mechanism 4 includes a gearbox 41. The left side of the gearbox 41 is fixedly connected to the right side of the support column 3, serving as the transmission protection housing of the lifting mechanism 4. It not only secures the internal transmission components but also isolates them from dust and impurities to prevent affecting transmission accuracy. Simultaneously, it provides a stable mounting platform for subsequent components. The gearbox 41 has a rotatably connected main shaft 42, which serves as the power input and transmission core shaft. External rotation can drive the components on the shaft to rotate synchronously, making it a key component for lifting transmission. A gear 43 is fixedly connected externally to the main shaft 42 to transmit the motion of the main shaft 42. Moving to the subsequent components, the support column 3 is internally slidably connected to a lifting rod 44, which serves as a vertical lifting actuator. The top is connected to the support mechanism 5, which can drive the decorative panel to rise and fall synchronously. The outside of the gear 43 meshes with the outside of the lifting rod 44. Through meshing with the rack structure of the lifting rod 44, the rotational motion of the main shaft 42 is converted into the linear motion of the lifting rod 44. The outside of the main shaft 42 is provided with a self-locking component 45, which is used to lock the rotation of the main shaft 42 and prevent the lifting rod 44 from falling on its own due to the reverse rotation of the main shaft 42 when bearing the weight of the ceiling, thus ensuring the stability of the height after lifting. The self-locking assembly 45 includes a ratchet 451, which is internally fixedly connected to the outside of the main shaft 42 and rotates synchronously with the main shaft 42. The ratchet teeth on its outer periphery engage with a fixed pawl 453 to achieve one-way locking of the main shaft 42. A fixed rod 452 is rotatably connected inside the gearbox 41, serving as the fulcrum for the fixed pawl 453, allowing the fixed pawl 453 to rotate flexibly around it, ensuring precise engagement or disengagement with the ratchet teeth of the ratchet 451. A fixed pawl 453 is fixedly connected to the outside of the fixed rod 452, and the outside of the ratchet 451 engages with the outside of the fixed pawl 453. By engaging with the ratchet teeth of the ratchet 451, the ratchet 451 is restricted to rotating only in the upward direction of the lifting rod 44. To descend, the engagement must be disengaged. The fixed pawl 453 is internally fixedly connected to a lever 454, which passes through the side wall of the gearbox 41. The outer end is for manual operation by the operator, and the inner end drives the fixed pawl 453 to rotate. This is the operating component for releasing the self-locking mechanism. Two return springs 455 are fixedly connected to the outside of the lever 454. In the natural state, they generate a rebound force. When the lever 454 is released, it can be pulled to return to its original position, thereby driving the fixed pawl 453 to re-engage with the ratchet 451 and restore the self-locking mechanism. The other end of the two return springs 455 is fixedly connected to a support rod 456, which serves as a support structure for the return springs 455 and provides a fulcrum for the springs to accumulate elastic force. The main shaft 42 is externally fixedly connected to a handle 457, which provides power to the main shaft 42 by cranking the handle 457.

[0011] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 The support mechanism 5 includes a crossbar 51, the bottom of which is fixedly connected to the top of the lifting rod 44, serving as the lateral basic frame of the support mechanism 5. The top of the crossbar 51 supports the decorative panel, and an internal sliding channel is machined for subsequent components to slide. Two extension rods 52 are slidably connected inside each crossbar 51, allowing them to slide outwards / inwards along the channels of the crossbar 51. Adjusting the extension length changes the lateral span of the support mechanism 5, adapting to decorative panels of different lengths. A telescopic rod 53 is fixedly connected inside each extension rod 52, allowing it to extend and retract within the extension rod 52 to provide support for subsequent components. To provide guidance and prevent deviation, a spring 54 is sleeved on the outside of the telescopic rod 53, which always exerts an upward elastic force on the telescopic rod 53, pushing the subsequent components into the positioning hole for fixation. A fixing protrusion 55 is fixedly connected to the top of the telescopic rod 53, which is inserted into the positioning hole of the crossbar 51 under the action of the spring 54, so as to achieve relative fixation between the extension rod 52 and the crossbar 51. Pressing can release the positioning. A folding component 56 is provided on the far side of the two extension rods 52 to further extend the bearing length. When not in use, it can be folded to reduce space occupation. The folding assembly 56 includes two outer shells 561. The adjacent sides of the two outer shells 561 are fixedly connected to the distant sides of two extension rods 52, serving as the protection and mounting base for the folding assembly 56. Internal space is reserved to accommodate internal components, and positioning holes are machined for the insertion of fixed parts. Two rotating shafts 562 are fixedly connected inside each outer shell 561, serving as fulcrums for the rotation of subsequent components, allowing the components to unfold outwards or retract inwards. Folding rods 563 are rotatably connected to the outside of the rotating shafts 562. When unfolded, they are perpendicular to the extension rods 52, increasing the load-bearing length; when retracted... The folding rod 563 folds inward to reduce space occupation. A telescopic rod 564 is fixedly connected inside the folding rod 563. The telescopic rod 564 can extend and retract inside the folding rod 563 to guide subsequent components. A spring 565 is sleeved on the outside of the telescopic rod 564, which always generates an upward elastic force on the telescopic rod 564 to push the subsequent components into the positioning hole for fixation. A fixing protrusion 566 is fixedly connected to the top of the telescopic rod 564. Under the action of the spring 565, it is inserted into the unfolding / folding positioning hole of the outer shell 561 to fix the state of the folding rod 563. Pressing it can release the positioning.

[0012] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 The fixed protrusion 55 is externally slidably connected to the inside of the crossbar 51. The inner wall of the crossbar 51 is machined with positioning holes that match the fixed protrusion 55. The fixed protrusion 55 is fixed by being embedded in the protrusion. The fixed protrusion 55 is externally slidably connected to the inside of the extension rod 52. The extension rod 52 is machined with through holes for the fixed protrusion 55 to slide up and down. The fixed protrusion 566 is externally slidably connected to the inside of the outer shell 561. The inner wall of the outer shell 561 is machined with two sets of positioning holes for unfolding / folding, which can be used to fix the folding rod 563 in different states. The fixed protrusion 566 is externally slidably connected to the inside of the folding rod 563. The folding rod 563 is machined with through holes for the fixed protrusion 566 to slide up and down. The toggle lever 454 is externally slidably connected to the inside of the gear box 41. The side wall of the gear box 41 is machined with elongated holes for the toggle lever 454 to slide laterally, ensuring operational flexibility. The two ends of the support rod 456 are fixedly connected to the inside of the gear box 41, providing stable fixation for the support rod 456 and ensuring the force balance of the return spring 455.

[0013] Working principle: When the worker places the decorative panel on the support mechanism 5, and the lifting mechanism is needed to complete the installation of the decorative panel, first turn the handle 457. The driving force of the handle 457 drives the main shaft 42 to rotate, and the gear 43 fixed on its outside rotates synchronously. Because the gear 43 meshes with the teeth on the outside of the lifting rod 44, the rotational motion of the main shaft 42 is converted into the linear motion of the lifting rod 44, which drives the top support mechanism 5 and the decorative panel it carries to rise to adapt to different floor heights. At the same time, the self-locking component 45 meshes with the fixed pawl 453 driven by the ratchet 451 and the return spring 455, which restricts the reverse rotation of the ratchet 451 and completes the self-locking of the mechanism. When the lifting rod 44 is lowered, when the height needs to be lowered, the actuating lever 454 on the gear box 41 is moved, which drives the fixed pawl 453 to rotate around the fixed rod 452 and disengage from the ratchet 451, releasing the self-locking. The lifting rod 44 can then be lowered by gravity or by turning the handle 457 in the opposite direction. After the work is completed, the mechanism needs to be folded and stored. The operator can press the fixing protrusion 55 to compress the spring 54, causing the fixing protrusion to disengage from the unfolding positioning hole of the crossbar 51, releasing the fixation of the extension rod 52 and allowing it to slide inward. When it slides to the folding positioning hole of the crossbar 51, the pressure accumulated by the spring pushes the fixing protrusion 55 out, fixing the extension rod 52. The telescopic rod 53 is mainly used to guide the spring 54 and the fixing protrusion 55 to prevent displacement. After the horizontal folding is completed, press the fixing protrusion 566 to compress the spring 565. The folding rod 563 folds inward around the rotating shaft 562 inside the outer shell 561. After rotating to the folding positioning hole set on the outer shell 561, the spring 565 releases the pressure, embedding the fixing protrusion 566 into the folding positioning hole of the outer shell 561 for storage and fixation. This completes the storage and folding of the overall structure, reducing the space occupied when not in use. To unfold, simply reverse the operation.
