Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, and in particular to a multi-angle adjustable connector for a ceiling conversion layer. Background Technology

[0002] Traditional decorative ceiling transition layers often use space frame ball joints as the primary connection method. For example... Figure 1 and Figure 2 As shown, the traditional installation process for a large-space space frame ceiling transition layer typically involves the following steps: bottom cross steel plate of the space frame bolt ball, adapter, screw, rotating disc, and N-type connector to complete the overall installation. The transition layer descends from the cross steel plate of the space frame bolt ball, connects to the disc via connectors and screws, the suspension rod is responsible for height adjustment, and the rotating disc handles fine-tuning in four directions. The four-way transition layer joists are connected to the rotating disc via N-type connectors, thus completing the installation of the overall space frame decorative transition layer. This design allows for rapid assembly and installation in regular rectangular ceiling joist systems, but its limitations become apparent when dealing with large, irregularly shaped decorative ceilings. The N-type connector can only adjust the angle in four directions simultaneously for positioning, and can only be used with... Figure 3 The rectangular grid system shown has been slightly adjusted in height and rotation angle.

[0003] Traditional N-type connectors have the following problems:

[0004] 1. Unable to accommodate angle changes: Traditional N-type connectors and rotating discs are fixed in space and can only be adjusted less than 10° left and right. Once locked in two directions, there is no angle change in the other two directions. Precise insertion is required to complete the overall installation. If there is an angle deviation between the rotating disc and the N-type connector, the conversion layer cannot be installed.

[0005] 2. Increased Applicability and Component Processing Difficulty: N-type connectors are mainly suitable for rectangular grid-type ceiling transition layers, and the component processing accuracy requirements are high. To ensure smooth insertion between the N-type connector and the rotating disc, the two U-shaped parts of the N-type connector can only be manually welded. Existing bending devices cannot be bent into shape, bringing great difficulties to production and processing. Due to insufficient adjustment capability and inability to cover most angle change requirements, the N-type connector faces the dual dilemma of "high processing cost" and "poor versatility."

[0006] 3. Construction relies on high-precision positioning and assembly, as well as manual experience. Installation requires multiple rotations and adjustments to the adapter positions, depending on the worker's subjective judgment. This is inefficient and prone to cumulative errors due to individual differences, posing a risk of large-scale implementation failures in certain areas. This ultimately affects the overall aesthetic appeal of the finished product. Utility Model Content

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] A multi-angle adjustable connector for a ceiling transition layer includes a bolt ball connector, a hanger, a rotating disk, and a C-shaped connector. The bolt ball connector, hanger, and rotating disk are connected sequentially from top to bottom. The C-shaped connector is detachably installed on the outer wall of the rotating disk. The C-shaped connector includes a C-shaped connecting block and a U-shaped connecting block. The bottom surface of the C-shaped connecting block and the bottom surface of the U-shaped connecting block are the same. The two sides of the C-shaped connecting block are respectively attached to the upper and lower end surfaces of the rotating disk. The C-shaped connecting block is provided with connecting bolts that pass through the two sides sequentially. The axis of the connecting bolts is parallel to the axis of the rotating disk. When the C-shaped connecting block is connected to the rotating disk, the side wall of the rotating disk is located between the bottom surface of the C-shaped connecting block and the connecting bolts.

[0009] Furthermore, the bolt ball connector includes a connecting base plate and connecting vertical plates. Four connecting vertical plates are provided and symmetrically arranged on the upper end face of the connecting base plate. A gap is left between the four connecting vertical plates, and the top view of the gap is cross-shaped.

[0010] Furthermore, the upper and lower ends of the boom are provided with external threads, wherein the upper end of the boom is threadedly connected to the center of the connecting base plate, and the lower end of the boom is threadedly connected to the center of the rotating disk.

[0011] Furthermore, both the upper and lower ends of the boom are connected to locking nuts.

[0012] Furthermore, the inner wall of the rotating disk is provided with cross-shaped reinforcing ribs.

[0013] Furthermore, the lengths of the two sides of the C-shaped connecting block are less than the lengths of the two sides of the U-shaped connecting block.

[0014] Furthermore, the C-shaped connecting block and the U-shaped connecting block are integrally forged from cross steel plates.

[0015] The beneficial effects of this utility model are:

[0016] 1. The C-type connecting block and the U-type connecting block are integrally forged from cross steel plates, which can significantly improve the overall processing efficiency and reduce human error, thereby reducing costs by 30%.

[0017] 2. The C-type connector can be adjusted to 90° left and right, providing a large adjustment range. It is suitable for installation in large spaces with irregularly shaped space frame decorative ceiling transition layers. When connecting with the rotating disc, the connecting bolts do not need to be precisely inserted into the rotating disc. This ensures connection strength while reducing the precision requirements during installation, thereby reducing rework rate and improving installation efficiency. Attached Figure Description

[0031] refer to Figures 4-7 As shown, one embodiment of this utility model is as follows:

[0032] A multi-angle adjustable connector for a ceiling transition layer includes a bolt ball connector 1, a hanger rod 2, a rotating disk 3, and a C-shaped connector 4. The bolt ball connector 1, hanger rod 2, and rotating disk 3 are connected sequentially from top to bottom. The C-shaped connector 4 is detachably installed on the outer wall of the rotating disk 3. The C-shaped connector 4 includes a C-shaped connecting block 401 and a U-shaped connecting block 402, wherein the C-shaped connecting block 401 is used to connect to the rotating disk 3, and the U-shaped connecting block 402 is used to connect to the ceiling joists. The bottom surface of the C-shaped connecting block 401 is the same as the bottom surface of the U-shaped connecting block 402. The two sides of the C-shaped connecting block 401 are respectively attached to the upper and lower surfaces of the rotating disk 3. The C-shaped connecting block 401 is provided with connecting bolts 403 that pass through the two sides in sequence. The axis of the connecting bolts 403 is parallel to the axis of the rotating disk 3. When the C-shaped connecting block 401 is connected to the rotating disk 3, the side wall of the rotating disk 3 is located between the bottom surface of the C-shaped connecting block 401 and the connecting bolts 403.

[0033] In this utility model, the C-shaped connecting block 401 and the U-shaped connecting block 402 are integrally forged from cross steel plates. The bottom surface of the C-shaped connecting block 401 and the bottom surface of the U-shaped connecting block 402 are the same. The lengths of the two sides of the C-shaped connecting block 401 are less than the lengths of the two sides of the U-shaped connecting block 402. The specific processing flow is as follows: Figure 6 and Figure 7 As shown, a cross-shaped steel plate is prepared. Using an existing bending device, such as a forging press, the upper and lower ends of the cross-shaped steel plate are first bent downwards to form a C-shaped connecting block 401. Then, the position of the cross-shaped steel plate is adjusted and flipped, and the left and right ends of the cross-shaped steel plate are bent upwards using the bending device to form a U-shaped connecting block 402. The forging forming method using a bending device can significantly improve the overall processing efficiency and reduce human error, resulting in a 30% reduction in cost. The processing cycle is reduced by 40%, and the applicability of the C-shaped connector 4 is improved.

[0034] In this utility model, when it is necessary to adjust the position of the C-type connector 4, simply loosen the connecting bolt 403 to easily move the C-type connector 4 to adjust its position. After the position of the C-type connector 4 is adjusted, tighten the connecting bolt 403. The tightened connecting bolt 403 generates a pre-tightening force on both sides of the C-type connector 401, restricting the up-down and left-right movement of the C-type connector 401, so that the C-type connector 401 can be pressed tightly on the rotating disk 3. The outer wall of the rotating disk 3 is located between the bottom surface of the C-type connector 401 and the connecting bolt 403. The blocking effect of the connecting bolt 403 also restricts the forward and backward movement of the C-type connector 401. Compared to the traditional N-type connector, the C-type connector 4 has a 90° adjustable angle, providing a large adjustment range. It is suitable for installation in large spaces with irregularly shaped grid decorative ceiling transition layers. Furthermore, when connecting with the rotating disc 3, the connecting bolt 403 does not require precise insertion into the rotating disc 3. This ensures connection strength while reducing the precision requirements during installation, thereby reducing rework rate and improving installation efficiency.

[0035] Specifically, the bolt ball connector 1 includes a connecting base plate 101 and connecting vertical plates 102. Four connecting vertical plates 102 are symmetrically arranged on the upper surface of the connecting base plate 101, such as... Figure 5 As shown, there is a gap between the four connecting vertical plates 102. The top view of the gap is cross-shaped and matches the cross steel plate on the ceiling bolt ball. That is, the cross steel plate can be inserted into the gap. The connecting vertical plate 102 is provided with a connecting hole. The connecting hole and the cross steel plate can be fixedly connected by bolts, which serves as the main force for connecting with the ceiling transition layer.

[0036] The upper and lower ends of the suspension rod 2 are provided with external threads. The upper end of the suspension rod 2 is threaded to the center of the connecting base plate 101, and the lower end of the suspension rod 2 is threaded to the center of the rotating disk 3. In use, the position of the suspension rod 2 in the connecting base plate 101 can be adjusted by rotating the suspension rod 2, thereby adjusting the height of the suspension rod 2 and the rotating disk 3. At the same time, the height of the rotating disk 3 on the suspension rod 2 can also be adjusted by rotating the rotating disk 3. In addition, locking nuts 5 are connected to both the upper and lower ends of the suspension rod 2. After the positions of the suspension rod 2 and the rotating disk 3 are adjusted, the locking nuts 5 can be installed on the suspension rod 2 to fix the positions of the suspension rod 2 and the rotating disk 3.

[0037] To ensure the stability of the rotating disk 3, the rotating disk 3 is provided with a cross reinforcing rib 301. The cross reinforcing rib 301 is fixedly installed on the inner wall of the rotating disk 3 by welding. The cross reinforcing rib 301 can support the interior of the rotating disk 3 and prevent the rotating disk 3 from deforming.
