Each of the opposite sidewalls of the first and second keels has mounting screw holes, and fixing components are installed in both screw holes. An adjusting connecting mechanism is installed between the two fixing components. The distance between the first and second keels can be adjusted by the adjusting connecting mechanism, thereby facilitating the adjustment of the height of the aluminum ceiling panels installed in the second keel. However, the aforementioned positioning device for decorative ceiling installation uses multi-stage gear transmission, resulting in a complex structure and high manufacturing and maintenance costs.

[0004] Therefore, this application provides an adjustable ceiling installation and positioning device to solve the above problems. Utility Model Content

[0005] This application provides an adjustable positioning device for installing decorative ceilings, which aims to solve the problems mentioned in the background art of existing positioning devices for installing decorative ceilings, which use multi-stage gear transmission, have complex structures, and have high manufacturing and maintenance costs.

[0006] To achieve the above objectives, this application provides the following technical solution: an adjustable ceiling installation and positioning device, comprising an adjustment component, wherein the adjustment component is equipped with a keel connector for connecting keel rods, the adjustment component comprising a connecting seat welded to the keel connector at the center of the ceiling, two first hinge rods symmetrically hinged to the top of the connecting seat, the other ends of the two first hinge rods respectively hinged to a fixed hinge seat and a sliding hinge seat, a driving mechanism provided on the fixed hinge seat and the sliding hinge seat for driving the fixed hinge seat and the sliding hinge seat to move closer or further apart from each other, two second hinge rods respectively hinged to the top of the fixed hinge seat and the sliding hinge seat, and a mounting seat hinged to the top of the two second hinge rods for fixed installation on the ceiling.

[0007] The drive mechanism includes a lead screw rotatably mounted on the fixed hinge seat, with its other end passing through and screwed to the sliding hinge seat, and a motor fixedly mounted on the fixed hinge seat with its output shaft connected to the lead screw. This eliminates the need for multi-stage gear transmission, employing a single lead screw and motor drive, reducing the number of parts and assembly complexity. The lead screw transmission, combined with a scissor mechanism, achieves stepless adjustment, avoiding errors caused by gear transmission backlash and reducing structural complexity. The self-locking function ensures that the ceiling will not shift due to external forces after fixing, improving construction safety, simplifying the structure, reducing manufacturing costs, and making subsequent maintenance and replacement simpler, thus reducing maintenance costs.

[0008] Preferably, the keel connector includes a cross connector, a T-shaped connector, and a corner connector, and the connector is welded to the cross connector located in the center of the ceiling.

[0009] Preferably, the top of each keel connector is connected to a telescopic rod for installation on the ceiling to move the keel connector closer to or further away from the ceiling.

[0010] Preferably, the telescopic rod includes a sleeve rod connected to the keel connector, an inner rod fitted inside the end of the sleeve rod away from the keel connector and moving axially, and a fixing plate fixedly connected to the end of the inner rod away from the sleeve rod for connecting to the ceiling.

[0011] Preferably, both the fixing plate and the lifting base have a plurality of bolt holes arranged in a ring array.

[0012] Preferably, each of the keel connectors has a threaded head at its central position for screwing into the sleeve rod.

[0013] Preferably, the input end of the motor is connected to the output end of an external remote control device.

[0014] This adjustable ceiling installation and positioning device abandons multi-stage gear transmission and adopts a single lead screw and motor drive, reducing the number of parts and assembly complexity. The lead screw transmission, combined with the scissor mechanism, achieves stepless adjustment, which not only avoids errors caused by gear transmission backlash but also reduces structural complexity. The self-locking function not only ensures that the ceiling will not shift due to external forces after it is fixed, improving construction safety, but also simplifies the structure, reduces manufacturing costs, and makes subsequent maintenance and replacement simpler, reducing maintenance costs.

[0015] This adjustable ceiling installation and positioning device uses an external remote control to operate the motor drive, improving adjustment efficiency and saving manpower. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] This embodiment provides an adjustable ceiling installation and positioning device for architectural decoration, such as... Figures 1-2 As shown, the adjustable ceiling installation and positioning device includes an adjustment component 2, which is equipped with a keel connector 1 for connecting keel rods. The adjustment component 2 includes a connecting seat 21 welded to the keel connector 1 at the center of the ceiling, two first hinge rods 22 symmetrically hinged to the top of the connecting seat 21, a fixed hinge seat 23 and a sliding hinge seat 231 respectively hinged to the other ends of the two first hinge rods 22, a drive mechanism 26 provided on the fixed hinge seat 23 and the sliding hinge seat 231 for driving the fixed hinge seat 23 and the sliding hinge seat 231 to move closer or further apart, two second hinge rods 24 respectively hinged to the top of the fixed hinge seat 23 and the sliding hinge seat 231, and a hanging seat 25 hinged to the top of the two second hinge rods 24 for fixing the ceiling.

[0024] The drive mechanism 26 includes a lead screw 261 rotatably mounted on a fixed hinge seat 23 and having its other end pass through and screwed to a sliding hinge seat 231, and a motor 262 fixedly mounted on the fixed hinge seat 23 and having its output shaft connected to the lead screw 261.

[0025] In use, the mounting base 25 is fixed to the ceiling, and the keel connector 1 is welded to the center of the ceiling keel. The adjustment component 2 connects the mounting base 25 and the keel connector 1 through a scissor mechanism to form a stable support frame. When the ceiling height needs to be adjusted, the motor 262 is started, driving the lead screw 261 to rotate, and the sliding hinge 231 moves along the axial direction of the lead screw 261. The change in the distance between the sliding hinge 231 and the fixed hinge 23 causes the angle of the scissor mechanism to change, pushing the keel connector 1 to rise and fall vertically. The direction of lifting and lowering is controlled by the forward and reverse rotation of the motor 262 to achieve precise adjustment of the ceiling height. After reaching the target height, the motor 262 is turned off, and the lead screw 261 locks itself to fix the current position. If fine adjustment is required, the motor 262 can be driven in a small range by the controller to achieve millimeter-level precision adjustment.

[0026] Specifically, the keel connector 1 includes a cross connector 11, a T-shaped connector 12, and a corner connector 13. The connector 21 is welded to the cross connector 11 located in the center of the ceiling. The three types of connectors cover common ceiling shapes, reducing the need for customized processing. The standardized connectors can be pre-assembled, requiring only simple splicing on site, thus shortening the construction cycle.

[0027] Furthermore, the top of each keel connector 1 is connected to a telescopic rod 3 for installation on the ceiling to move the keel connector 1 closer to or away from the ceiling. The telescopic rod 3 includes a sleeve rod 31 connected to the keel connector 1, an inner rod 32 fitted inside the end of the sleeve rod 31 away from the keel connector 1 and moving axially, and a fixing plate 33 fixedly connected to the end of the inner rod 32 away from the sleeve rod 31 for connecting to the ceiling. Each keel connector 1 has a threaded head 34 at its central position for screwing into the sleeve rod 31. The telescopic rod 3 is composed of the sleeve rod 31, the inner rod 32 and the fixing plate 33, and is connected to the keel connector 1 through the threaded head 34. Each keel connector 1 can be equipped with a telescopic rod 3 independently to support the installation requirements of non-planar suspended ceilings. The telescopic rod 3 can be used with the adjustment component 2 to achieve stable adjustment and ensure the stability of the suspended ceiling surface during the adjustment process.

[0028] Understandably, both the fixing plate 33 and the hanging base 25 have several bolt holes 251 arranged in a ring array; the design of multiple bolt holes 251 evenly distributes the weight of the ceiling to the ceiling structure, reducing the risk of local stress concentration.

[0029] It should be noted that the input terminal of motor 262 is connected to the output terminal of an external remote control device; the input terminal of motor 262 is connected to an external remote control device, such as a handheld remote control or a mobile APP, to control the start, stop and turn of motor 262 through wireless signals. Construction personnel can operate it from the ground, avoiding the risks of working at height.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
