Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a ceiling support frame. Background Technology

[0002] In interior decoration and construction, suspended ceilings are used to decorate the top of a living space; simply put, they decorate the ceiling. Suspended ceilings are an important part of interior decoration, serving functions such as heat insulation, sound insulation, and sound absorption. They also conceal electrical, ventilation, air conditioning, communication, fire protection, and alarm wiring and equipment. When installing suspended ceilings using gypsum board, the support frame is usually first fixed to the ceiling using expansion bolts, then the joists are fixed to the support frame, and finally the gypsum board is fixed to the joists. Since most existing ceilings are flat, fixing the support frame first and then the joists to the vertically downward-facing support frame makes it difficult to provide stable support for the gypsum board when installing suspended ceilings on sloping roofs. Utility Model Content

[0003] This utility model provides a ceiling support frame that can be adjusted in angle and height to accommodate gypsum board ceilings on sloping roofs.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This utility model discloses a ceiling support frame, including a positioning plate. A fixed base is provided at one bottom end of the positioning plate, and a rotating plate is rotatably mounted on the fixed base. A first threaded shaft is rotatably mounted on the bottom of the positioning plate relative to the fixed base via a ball joint. A first threaded hole, cooperating with the first threaded shaft, is provided at the other end of the rotating plate relative to the fixed base. The first threaded shaft passes through the first threaded hole at the other end of the positioning plate. A square sleeve is provided at the bottom of the rotating plate. A second threaded shaft and a square sleeve rod are provided inside the sleeve. The top end of the second threaded shaft is rotatably mounted on the top of the sleeve. A rotating block is fixedly mounted on the outer side of the second threaded shaft near the top of the sleeve. The sleeve rod has a second threaded hole cooperating with the second threaded shaft. The bottom end of the second threaded shaft is threaded into the second threaded hole. The length of the sleeve rod is greater than the length of the sleeve. A positioning frame is provided at the bottom end of the sleeve rod.

[0006] Furthermore, the rotating plate has a mounting hole at the other end opposite to the fixed base, and a rotating shaft is rotatably disposed in the mounting hole. The rotating shaft rotates in the same direction as the rotating plate, and the first screw hole is formed on the rotating shaft.

[0007] Furthermore, the bottom of the positioning plate is provided with a fixing sleeve that mates with the ball joint, and the ball joint is rotatably connected within the fixing sleeve.

[0008] Furthermore, the fixing sleeve is a structural component made of ceramic material.

[0009] Furthermore, the two side walls of the fixed base are provided with opposing shaft holes, and the opposite side walls of the rotating plate are respectively provided with rotating shafts that cooperate with the corresponding shaft holes, and the rotating shafts are rotatably disposed in the corresponding shaft holes.

[0010] Furthermore, a pointer is fixedly provided at one end of the rotating shaft, and a scale is fixedly provided on the side wall of the fixed base opposite to the pointer.

[0011] The beneficial effects of this utility model are:

[0012] This application discloses a ceiling support frame. When supporting gypsum board in a sloping ceiling, a positioning plate is fixed to the ceiling wall using expansion bolts. The angle of the positioning frame is adjusted according to the required tilt angle of the gypsum board. The upper end of a first threaded shaft is rotatably connected to the positioning plate via a ball joint. A rotating plate is rotatably connected to a fixed seat at the bottom of the positioning plate. The lower end of the first threaded shaft is threaded through a first threaded hole in the rotating plate. The ball joint, the first threaded shaft, the rotating plate, the fixed seat, and the positioning plate constitute an angle adjustment structure. Rotating the first threaded shaft causes the end of the rotating plate relative to the first threaded shaft to move downwards away from the positioning plate, while the end of the rotating plate relative to the fixed seat rotates relative to the fixed seat, thereby adjusting the angle of the rotating plate. A sleeve is provided at the bottom of the rotating plate, and a threaded second threaded shaft and a sleeve rod are provided inside the sleeve. A positioning frame is provided at the bottom end of the sleeve rod, thereby adjusting the angle of the positioning frame at the bottom of the rotating plate to match the required tilt angle of the gypsum board during ceiling installation, thus completing the angle adjustment. The height of the positioning frame is adjusted according to the required distance from the wall to the gypsum board during installation. A sleeve is located at the bottom of the rotating plate, and a second threaded shaft is installed on the inner top of the sleeve. A rotating block is fixedly installed on the outer top of the second threaded shaft. A second threaded hole is provided in the sleeve rod, and the bottom end of the second threaded shaft is threaded into the second threaded hole of the sleeve rod. A positioning frame is installed at the bottom end of the sleeve rod. The sleeve, second threaded shaft, rotating block, sleeve rod, and positioning frame constitute the height adjustment structure. Initially, the bottom end of the sleeve rod of the second threaded shaft abuts against the bottom of the second threaded hole of the sleeve rod. Rotating the rotating block causes the sleeve rod to rotate relative to the threaded shaft, moving the sleeve rod downwards along the axial direction of the second threaded shaft. The sleeve rod slides downwards within the sleeve, and the positioning frame at the bottom end of the sleeve rod moves downwards. Adjustment is completed until the required distance from the ceiling gypsum board to the wall is achieved. The gypsum board fixing keel is then fixed inside the positioning frame, and the ceiling gypsum board is fixed to the keel. In summary, the angle adjustment structure consisting of a ball joint, a first threaded shaft, a rotating plate, a fixed seat, and a positioning plate, and the height adjustment structure consisting of a sleeve, a second threaded shaft, a rotating block, a sleeve rod, and a positioning frame, can achieve both angle and height adjustment of the ceiling gypsum board, making it particularly suitable for gypsum board ceilings on sloping roofs.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, a ceiling support frame of this utility model includes a positioning plate 1. A fixed base 2 is provided at one bottom end of the positioning plate 1. A rotating plate 4 is rotatably mounted on the fixed base 2. A first threaded shaft 5 is rotatably mounted on the bottom of the positioning plate 1 relative to the fixed base 2 via a ball joint 6. A first threaded hole that mates with the first threaded shaft 5 is provided at the other end of the rotating plate 4 relative to the fixed base 2. The first threaded shaft 5 passes through the first threaded hole at the other end of the positioning plate 1. A square sleeve 1 is provided at the bottom of the rotating plate 4. 1. A second threaded shaft 14 and a square sleeve rod 12 are vertically arranged inside the sleeve 11. The top end of the second threaded shaft 14 is rotatably mounted on the top of the sleeve 11. A rotating block 15 is fixedly arranged on the outer side of the second threaded shaft 14 near the top of the sleeve 11. The sleeve rod 12 is vertically arranged with a second threaded hole that mates with the second threaded shaft 14. The bottom end of the second threaded shaft 14 is threaded into the second threaded hole. The length of the sleeve rod 12 is greater than the length of the sleeve 11. A positioning bracket 13 is provided at the bottom end of the sleeve rod 12. The fixed seat 2 is a U-shaped fixed seat 2. The rotating plate 4 is rotatably mounted between the two side walls of the U-shaped fixed seat 2. The fixed seat 2 is welded to the bottom of the positioning plate 1. The sleeve 11 is welded to the bottom of the rotating plate 4. The top end of the second threaded shaft 14 is welded to the inner side of the top of the sleeve 11. The rotating block 15 is welded to the upper end of the second threaded shaft 14. A through hole is opened on the upper side wall of the sleeve 11 for installing the rotating block 15 and facilitating its rotation. Furthermore, the through hole is extended to a position near the lower end of the sleeve 11 to facilitate observation of the downward sliding of the sleeve rod 12. A red ring-shaped marking line is sprayed circumferentially on the upper outer side wall of the sleeve rod 12. If the ring-shaped marking line is exposed, the rotating block 15 is stopped from rotating. The lower end of the second threaded shaft 14 is always kept within the second threaded hole of the sleeve rod 12 to prevent the sleeve rod 12 from sliding out of the sleeve 11 and falling off. If this happens, a longer ceiling support frame for the sleeve 11, sleeve rod 12, and second threaded shaft 14 needs to be replaced.

[0022] Based on the above structure, a ceiling support frame is used to support the gypsum board of a sloping ceiling. An expansion bolt is used to fix a positioning plate to the ceiling wall. The angle of the positioning frame is adjusted according to the required tilt angle of the gypsum board. The upper end of the first threaded shaft 5 is rotatably connected to the positioning plate 1 via a ball joint 6. A rotating plate 4 is rotatably connected to a fixed seat 2 at the bottom of the positioning plate 1. The lower end of the first threaded shaft 5 is threaded through the first threaded hole of the rotating plate 4. The ball joint 6, the first threaded shaft 5, the rotating plate 4, the fixed seat 2, and the positioning plate 1 form an angle... Adjust the structure by rotating the first threaded shaft 5. The end of the rotating plate 4 relative to the first threaded shaft 5 moves downward away from the positioning plate 1. The end of the rotating plate 4 relative to the fixed seat 2 rotates relative to the fixed seat 2 to adjust the angle of the rotating plate 4. A sleeve 11 is provided at the bottom of the rotating plate 4. A threaded second threaded shaft 14 and a sleeve rod 12 are provided inside the sleeve 11. A positioning frame 13 is provided at the bottom end of the sleeve rod 12 to adjust the angle of the positioning frame 13 at the bottom of the rotating plate 4. Adjust it to be the same as the tilt angle of the ceiling gypsum board required during ceiling installation, thus completing the angle adjustment. The height of the positioning frame is adjusted according to the required distance from the plasterboard to the wall during installation. A sleeve 11 is located at the bottom of the rotating plate 4. A second threaded shaft 14 is installed on the inner top side of the sleeve 11. A rotating block 15 is fixedly installed on the outer top side of the second threaded shaft 14. A second threaded hole is provided in the sleeve rod 12. The bottom end of the second threaded shaft 14 is threaded into the second threaded hole of the sleeve rod 12. A positioning frame 13 is installed at the bottom end of the sleeve rod 12. The sleeve 11, second threaded shaft 14, rotating block 15, sleeve rod 12, and positioning frame 13 constitute a height adjustment structure. Initially, the bottom end of the second threaded shaft 14 abuts against the bottom of the second threaded hole of the sleeve 12. Rotating the rotating block 15 causes the sleeve 12 to rotate relative to the second threaded shaft 14, moving it downwards along the axial direction of the second threaded shaft 14. The sleeve 12 slides downwards within the sleeve 11, and the positioning bracket 13 at the bottom of the sleeve 12 moves downwards. Adjustment is made to the required distance from the ceiling plasterboard to the wall during installation, completing the height adjustment. The plasterboard fixing keel is then fixed within the positioning bracket 13, and the ceiling plasterboard is fixed to the keel. In summary, the angle adjustment structure composed of the ball joint 6, the first threaded shaft 5, the rotating plate 4, the fixing seat 2, and the positioning plate 1, and the height adjustment structure composed of the sleeve 11, the second threaded shaft 14, the rotating block 15, the sleeve 12, and the positioning bracket 13, completes the angle and height adjustment of the ceiling plasterboard, making it particularly suitable for gypsum board ceilings on sloping roofs.

[0023] As one implementation method, such as Figure 1 , Figure 2 As shown, the rotating plate 4 has a mounting hole at the other end opposite to the fixed base 2. A rotating shaft 8 is rotatably installed in the mounting hole. The rotating shaft 8 rotates in the same direction as the rotating plate 4. The first screw hole is opened on the rotating shaft 8.

[0024] The rotating shaft 8 is designed so that it rotates along with the first threaded shaft 5 during rotation, thereby causing the angle between the rotating plate 4 and the first threaded shaft 5 to change adaptively and preventing the rotating plate 4 and the first threaded shaft 5 from jamming.

[0025] As one implementation method, such as Figure 1 , Figure 2 As shown, the bottom of the positioning plate 1 is provided with a fixing sleeve 7 that mates with the ball joint 6, and the ball joint 6 is rotatably connected inside the fixing sleeve 7.

[0026] The fixing sleeve 7 facilitates the installation and rotation of the ball joint 6. A spherical groove can be made at the bottom of the positioning plate 1, and the fixing sleeve 7 can be installed in the spherical groove at the bottom of the positioning plate 1 by embedding. The spherical groove covers most of the ball joint 6, such as two-thirds of the ball joint 6, to prevent the ball joint 6 from falling out of the spherical groove.

[0027] As one implementation method, such as Figure 1 , Figure 2 As shown, the fixing sleeve 7 is a structural component made of ceramic material.

[0028] The ceramic-made fixing sleeve 7 reduces the friction between the fixing sleeve 7 and the ball joint 6, allowing the ball joint 6 to rotate smoothly within the fixing sleeve 7, reducing frictional loss between the fixing sleeve 7 and the ball joint 6. At the same time, the ceramic-made fixing sleeve 7 has strong corrosion resistance, ensuring long-term reliability.

[0029] As one implementation method, such as Figure 1 , Figure 2 As shown, the two side walls of the fixed base 2 are provided with opposite shaft holes, and the opposite side walls of the rotating plate 4 are respectively provided with rotating shafts 3 that cooperate with the corresponding shaft holes. The rotating shafts 3 are rotatably disposed in the corresponding shaft holes.

[0030] The rotating plate 4 and the fixed base 2 are connected by a rotating shaft 3 and a shaft hole, so that the rotating plate 4 can rotate within the fixed base 2. The structure is simple. The two side walls of the fixed base 2 limit the rotating plate 4 and reduce axial movement. The rotating shaft 3 and the shaft hole are tightly connected to reduce radial runout and have good stability.

[0031] As one implementation method, such as Figure 1 , Figure 2 , Figure 3 As shown, a pointer 9 is fixedly installed at one end of the rotating shaft 3, and a dial 10 is fixedly installed on one side wall of the fixed base 2 relative to the pointer 9.

[0032] Rotating the first threaded shaft 5 causes the rotating shaft 3 to rotate, which in turn causes the pointer 9 to rotate. When the angle indicated by the pointer 9 on the scale 10 is the same as the tilt angle of the gypsum board required during ceiling installation, stop rotating the first threaded shaft 5. The pointer 9 and the scale 10 work together to improve the angle adjustment accuracy, reduce errors, and improve the installation accuracy and quality of the gypsum board.

[0033] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
