Description

Technical Field

[0001] This utility model belongs to the field of ceiling keel technology, specifically relating to a stable and easy-to-assemble ceiling keel. Background Technology

[0002] Ceiling joists are structures used to smoothly fix ceiling decorative panels to the bottom of the roof, especially for decorative ceilings, which are often made by using joists as a framework and then covering them with gypsum board. Ceiling joists are divided into wooden joists and light steel joists. To improve the installation efficiency of ceiling joists, modular ceiling joist structures are often used for interior ceiling installation.

[0003] The existing technology includes a modular ceiling keel structure with patent publication number CN220150657U. This patent enables the rapid connection and installation of modular ceiling keels without the need for tedious bolt tightening, thus improving the construction efficiency of ceiling work. It locks the insert rods and screws, preventing movement of the insert rods and reverse rotation of the screws, thereby preventing loosening due to external forces or vibrations and ensuring the installation firmness of the modular ceiling keel. It is suitable for fixing ceiling decorative panels. However, in practical use, it still has the following shortcomings: From a practical standpoint, the horizontal and vertical channel steels of this structure require welding for fixed connection. Welding requires professional welders, resulting in high labor costs. Furthermore, transporting welding equipment to high-altitude work sites is difficult. Moreover, the welded joints become "permanent connections," making it difficult to meet the needs of frequent renovations in exhibition halls and commercial spaces, reducing the flexibility of the structure.

[0004] Therefore, a stable and easy-to-assemble ceiling keel is needed to solve the problems of existing technologies where horizontal and vertical channel steels need to be welded and fixed, which makes operation difficult and reduces the flexibility of use. Utility Model Content

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a stable and easy-to-assemble ceiling keel, including a main keel 1, a connector 2, an auxiliary keel 3, a connecting mechanism 4, and a fixing rod 5. The main keels 1 are connected to each other by the connector 2, the auxiliary keels 3 are connected to each other by the connector 2, the main keel 1 and the auxiliary keel 3 are connected by the connecting mechanism 4, and the fixing rod 5 is fixedly connected to the top of the auxiliary keel 3.

[0024] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the main keel 1 is composed of a keel body 101 and a protrusion 103. The protrusion 103 is fixedly connected to one end of the keel body 101. The other end of the keel body 101 is provided with a groove 102 that matches the protrusion 103. The short side of the protrusion 103 is symmetrically provided with a first connecting hole 104. The front and rear sides of the groove 102 are symmetrically provided with a second connecting hole 105. One end of the keel body 101 is symmetrically provided with a third connecting hole 106.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connector 2 consists of a U-shaped tube 201, a first connecting plate 202, a bolt 203, a second connecting plate 204, a threaded rod 205, a third connecting plate 206, and a turntable 207. The U-shaped tube 201 has symmetrically opened threaded grooves at both ends. The first connecting plate 202 slides on the outside of the U-shaped tube 201. The bolt 203 is adapted to the threaded groove. The second connecting plate 204 has symmetrically opened threaded blocks adapted to the threaded groove inside. The threaded rod 205 is threadedly connected to both sides of the second connecting plate 204. The third connecting plate 206 is rotatably connected to one end of the threaded rod 205. The turntable 207 is fixedly connected to the other end of the threaded rod 205.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the first connecting plate 202 and the threaded rod 205 are respectively provided with through holes that are compatible with the U-shaped tube 201.

[0027] The through holes facilitate the sliding of the third connecting plate 206 and the first connecting plate 202 outside the U-shaped tube 201, making it easy to disassemble the connector 2.

[0028] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the first connecting hole 104, the second connecting hole 105, and the third connecting hole 106 have the same dimensions, and are also the same as the dimensions of the U-shaped tube 201.

[0029] The rotation of the turntable 207 drives the movement of the third connecting plate 206, thereby adjusting the distance between the first connecting plate 202 and the third connecting plate 206 to accommodate keel bodies 101 of different thicknesses and improve the flexibility of the connector 2.

[0030] As can be seen from the above working process, the connecting parts 2 and 4 are both designed to be detachable. If a part is damaged, it can be replaced individually without the need for complete disassembly. This facilitates the quick installation and disassembly of the main keel 1 and the auxiliary keel 3, thereby improving the work efficiency of the staff.

[0031] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting mechanism 4 consists of a baffle 402, a bidirectional lead screw 403, a slide rod 404, a moving plate 405, a connecting block 406, a connecting plate 407, a first support plate 408, and a second support plate 409. The short side of the auxiliary keel 3 is provided with a through groove 401. The baffle 402 is symmetrically and fixedly connected above the through groove 401. The bidirectional lead screw 403 is rotatably connected between the two baffles 402, and a handle is fixedly connected to one end of the bidirectional lead screw 403. The slide rod 404 is fixedly connected between the two baffles 402. The moving plate 405 is symmetrically threaded to the outside of the threaded surface of the bidirectional lead screw 403, and the moving plate 405 is slidably connected to the slide rod 404.

[0032] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting block 406 passes through the through slot 401, the connecting block 406 is fixedly connected to the lower part of the movable plate 405, and the connecting plate 407 is fixedly connected to the lower part of the connecting block 406.

[0033] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the connecting plates 407 are arranged symmetrically on the left and right sides. The first support plate 408 is fixedly connected to the lower part of the left connecting plate 407, and the second support plate 409 is fixedly connected to the lower part of the right connecting plate 407. The first support plate 408 is arranged above the second support plate 409.

[0034] The first support plate 408 and the second support plate 409 form a staggered structure, which applies support force to the keel body 101, disperses the pressure distribution, avoids excessive stress on a single point that could cause keel deformation, and improves the overall structural rigidity.

[0035] The auxiliary keel 3 has the same structure as the main keel 1, both being provided with a keel body 101, a groove 102, a protrusion 103, a first connecting hole 104, a second connecting hole 105, and a third connecting hole 106. The two auxiliary keels 3 can be fixedly connected by the provided connector 2.

[0036] The solution has the following working process: When it is necessary to connect and fix two main keels 1 or two auxiliary keels 3, insert the protrusion 103 into the corresponding groove 102, so that the first connecting hole 104 and the second connecting hole 105 are aligned. Then slide the first connecting plate 202 to the end of the U-shaped tube 201 and fit the U-shaped tube 201 into the adjacent holes of the two keels. At this time, the U-shaped tube 201 is set inside the keel body 101. Then fit the third connecting plate 206 into the outside of the U-shaped tube 201. The second connecting plate 204 is threaded and fixed to the end of the U-shaped tube 201. At this time, the third connecting plate 206 and the second connecting plate 204 are set outside the keel body 101. Then fit the bolt 203 into the threaded groove of the U-shaped tube 201 and tighten it. Rotate the turntable 207 to drive the third connecting plate 206 to approach the outer surface of the keel body 101, complete the connection between the two keel bodies 101, and thus fix the connection node of the keel body 101.

[0037] Then, rotate the handle of the connecting mechanism 4 to drive the bidirectional lead screw 403 to rotate, which in turn causes the moving plate 405 to move towards the sliding rod 404. The moving plate 405 pushes the connecting block 406 and the connecting plate 407 to move towards each other, thus fixing the lower keel body 101. At the same time, the second support plate 409 is set above the first support plate 408 to support the keel body 101, thus completing the fixed connection between the main keel 1 and the auxiliary keel 3.

[0038] In summary: Both the connector 2 and the connecting mechanism 4 are designed to be detachable, allowing for individual replacement of damaged parts without the need for complete disassembly. This facilitates quick installation and disassembly of the main keel 1 and the auxiliary keel 3, thereby improving the work efficiency of the staff. Furthermore, the connector 2 and the connecting mechanism 4 allow for adjustment of the distance between the first connecting plate 202 and the third connecting plate 206, as well as the distance between the two connecting plates 407, thus accommodating main keels 1 or auxiliary keels 3 of different sizes and enhancing the flexibility of the structure.
