Adjustable suspended ceiling supporting frame

Abstract

The utility model discloses an adjustable suspended ceiling supporting frame which comprises a suspended ceiling plate and a supporting assembly, by arranging the supporting assembly, a worm is meshed with a worm gear by rotating a rotary knob, meanwhile, the worm gear and a first driven gear rotate coaxially, and after the first driven gear is meshed with a rack plate, the rack plate is driven to rotate coaxially. The rack plate drives the movable plate and the adjusting mechanism to synchronously ascend and adjust, and after the worm is adjusted to a certain height, when the worm stops rotating and the worm gear rotates, certain friction force is generated between the worm gear and the worm due to the trapezoidal section of the worm, so that the worm gear is difficult to freely rotate under the condition that power input is stopped, and the worm gear is prevented from rotating. Therefore, the self-locking effect is achieved. By arranging the adjusting mechanism, a driving motor drives a driving gear to enable four groups of driven gears II to drive eccentric rods to perform eccentric circle rotation, so that four groups of extension plates and supporting blocks are synchronously adjusted to perform telescopic length adjustment, and the distance between the supporting blocks is adjusted to achieve the auxiliary supporting effect on different areas of the suspended ceiling plate.

Description

Technical Field

[0001] This utility model relates to the field of ceiling support frame technology, specifically an adjustable ceiling support frame. Background Technology

[0002] Ceiling support frames are a type of support structure used in ceiling construction. They are mainly used to fix and support ceiling materials, ensuring the stability and safety of the ceiling. Ceiling support frames are widely used in ceiling construction in houses, especially in areas with large spans. They can effectively support ceiling materials and prevent sagging or deformation. However, existing ceiling support frames are inconvenient to store, making them difficult for workers to carry.

[0003] For example, CN202223352855.X discloses "A Ceiling Support Frame", which is equipped with components such as a fixed sleeve, a support rod, and a protrusion. By rotating the fixed sleeve, the fixed sleeve and the support rod will undergo threaded movement, allowing the support rod to slide inside the sleeve. This allows the position of the support rod inside the sleeve to be adjusted, making it convenient to adjust the height of the support plate and to conveniently store the sleeve.

[0004] Existing ceiling support frames mostly use apex support. However, even after partial apex support, the remaining corners of the ceiling are still tilted and sagging, making them prone to deformation. This not only fails to ensure the flatness of the ceiling but also indirectly affects the support efficiency of the ceiling installation. Utility Model Content

The movable plate is installed at the bottom of the adjustment plate, and the support block is fixedly connected to the bottom of the ceiling panel.

[0010] Preferably, the worm gear is horizontally disposed on the upper inner side of the support plate, and the left and right sides of the worm gear slide along the inner sides of the left and right ends of the movable plate, respectively, so that the rotation of the worm gear will not be interfered with when the movable plate is raised or lowered.

[0011] Preferably, the worm gear and the driven gear are horizontally fixed to the upper inner side of the support plate via a connecting rod, thereby fixing the worm gear and the driven gear to the same horizontal line and allowing for coaxial rotation adjustment.

[0012] Preferably, the rack plate is vertically fixed to the left front side inside the movable plate, and the movable plate is vertically slidable along the inner side of the support plate by meshing with the driven gear on the right side of the rack plate, and the driven gear provides additional support to the support plate.

[0014] Preferably, the extension plate is adjusted by moving back and forth along the driven gear two via an eccentric rod. The eccentric rod moves horizontally along the inner sliding groove at the rear end of the extension plate, thereby achieving the function of adjusting the extension plate's extension and retraction through eccentric rotation.

[0015] (3) Beneficial effects

[0016] This utility model provides an adjustable ceiling support frame. It has the following advantages: By setting up a support assembly, rotating a knob engages the worm gear and worm wheel. Simultaneously, the worm wheel and driven gear rotate coaxially. The driven gear meshes with a rack plate, causing the rack plate, movable plate, and adjustment mechanism to rise synchronously for adjustment. When adjusted to a certain height, and the worm gear stops rotating, the worm wheel's rotation, due to the worm's trapezoidal cross-section, generates friction between the worm and worm. This makes it difficult for the worm wheel to rotate freely when power input stops, thus achieving a self-locking effect.

[0017] This utility model provides an adjustable ceiling support frame. It has the following advantages: by setting up an adjustment mechanism, a drive motor drives a drive gear to cause four sets of driven gears to rotate eccentrically, thereby synchronously adjusting the extension length of the four sets of extension plates and support blocks. This allows for indirect adjustment of the spacing between the support blocks to achieve auxiliary support for different areas of the ceiling panel. Attached Figure Description

The driven gear 25 meshes with the right end of the rack plate 26 for rotation. The rack plate 26 is installed on the front left side of the movable plate 27. The movable plate 27 is installed at the bottom of the adjustment mechanism 28, and the adjustment mechanism 28 is fixedly connected to the bottom of the ceiling plate 1. Next, the worm gear 23 is horizontally set on the upper inside of the support plate 21, and the left and right sides of the worm gear 23 slide along the inner sides of the left and right ends of the movable plate 27 respectively. When the movable plate 27 is raised or lowered, it will not cause motion interference to the rotation of the worm gear 23. The worm wheel 24 and the inner middle of the driven gear 25 are horizontally fixed to the upper inside of the support plate 21 through the connecting rod, so that the worm wheel 24 and the driven gear 25 are horizontally fixed on the same horizontal line and can be adjusted to rotate coaxially. The rack plate 26 is vertically fixed to the front left inside of the movable plate 27, and the movable plate 27 meshes with the driven gear 25 through the right side of the rack plate 26 and slides vertically along the inner side of the support plate 21. The driven gear 25 also provides auxiliary support to the support plate 21.

[0028] Please see Figure 5 and 6This utility model provides an adjustable ceiling support frame technical solution: an adjustable ceiling support frame, the adjustment mechanism 28 includes an adjustment plate 281, a drive motor 282, a drive gear 283, a driven gear 284, an eccentric rod 285, an extension plate 286, a support block 287, and an auxiliary block 288. The drive motor 282 is installed in the middle of the inner side of the adjustment plate 281. The output end of the drive motor 282 is connected to the inner side of the middle of the drive gear 283 by a coupling. The drive gear 283 meshes with the driven gear 284 and rotates. An eccentric rod 285 is installed on the left side of the top of the driven gear 284. The eccentric rod 285 is slidably engaged with the inner rear end of the extension plate 286. A support block is fixed on the upper front end of the extension plate 286. 287, and the middle part of the extension plate 286 slides in conjunction with the inner side of the middle part of the auxiliary block 288. The movable plate 27 is installed at the bottom of the adjusting plate 281. The support block 287 is fixedly connected to the bottom of the ceiling plate 1. The driven gear 284, the eccentric rod 285, the extension plate 286, the support block 287 and the auxiliary block 288 are respectively provided in four sets. The four sets of driven gears 284 mesh with the four sides of the drive gear 283 to adjust, thereby achieving the effect of synchronous adjustment of the length of the four sides.

The eccentric rod 285 is adjusted horizontally along the inner side slide groove at the rear end of the extension plate 286, thereby achieving the function of adjusting the extension plate 286's extension and retraction through eccentric rotation.

[0029] In use, the worm 23 is rotated by turning the knob 22 on the upper right side of the support plate 21, and it meshes with the worm wheel 24.

When the rack plate 26, the movable plate 27 and the adjusting plate 281 are adjusted to a certain height, the rotation of the worm 23 is stopped. When the worm wheel 24 rotates, due to the trapezoidal cross section of the worm 23, a certain frictional force is generated between the worm wheel 24 and the worm 23. This makes it difficult for the worm wheel 24 to rotate freely when the input power is stopped, thus achieving a self-locking effect.

[0030] Subsequently, the drive motor 282 drives the drive gear 283 to make the four driven gears 284 respectively drive the four eccentric rods 285 to perform eccentric circular rotation. The four driven gears 284 are all movably rotated on the inner side of the adjustment plate 281 through the support rod. Then, the four eccentric rods 285 slide and adjust with the inner sliding grooves of the four extension plates 286 respectively. At the same time, the four eccentric rods 285 respectively drive the extension plates 286 and the support block 287 to adjust the extension length. The auxiliary block 288 improves the stability of the translation adjustment of the extension plates 286.

[0031] Subsequently, the support blocks 287, which unfold from all four sides, fit snugly against the bottom of the ceiling panel 1, greatly improving the support effect on the ceiling panel 1.
