[0002] The keel is the medium connecting the original structure of the building (ceiling) and the decorative finishing structure (decorative panels, suspended ceilings, soft packages and other finishing structures). As people's quality of life gets higher and higher, more and more people choose to install various beautiful and practical decorations on their indoor ceilings. The decoration and installation of the ceiling are inseparable from the suspended ceiling keel, especially the shaped ceilings, which are made of keels as frames and then covered with gypsum boards. The keel is made of light steel and is the main material for the ceiling. The suspended ceiling keel is connected to the hanger and provides an installation node for the surface cover panel. It is a connecting component in the suspended ceiling.

[0003] For example, a Chinese patent (publication number: CN213897756U) discloses a ceiling keel that is easy to disassemble and assemble, including a main keel and a secondary keel. The top of the main keel is installed with a hanger rod by bolts, the bottom of the main keel is installed with a secondary keel, a fixing device is installed inside the main keel, and the bottom of the fixing device passes through the bottom of the main keel and extends to the inside of the secondary keel. Fixing parts are installed on both sides of the main keel by bolts for easy disassembly and assembly, and when the fixing device between the secondary keel and the main keel falls off accidentally, the metal hose can play a role in receiving and protecting it.

[0004] The above technical solution still has the following defects: although the ceiling keel that is easy to disassemble and assemble is easy to disassemble and assemble, and the metal hose can play a protective role when the fixing device between the secondary keel and the main keel accidentally falls off, when in use, the main keel and the secondary keel are connected by screws and fastening nuts. When the operator disassembles and assembles it, he needs to use other tools to operate it, which is time-consuming and labor-intensive. Based on this, a keel fixing and positioning device for a decorative surface layer is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] See also Figure 1 A keel fixing and positioning device for a decorative surface layer in this embodiment includes a secondary keel 1, a connection box 2 is fixed to the upper surface of the secondary keel 1, a main keel 3 is attached to the upper surface of the connection box 2, a hanger 4 is installed on the top of the main keel 3 by bolts, and a fixing mechanism 5 is provided in the connection box 2 and penetrates to the outside of the connection box 2.

[0032] It should be noted that, through the cooperation between the fixing mechanism 5 and the connection box 2, the operator can more conveniently complete the installation, fixing or disassembly between the keel parts, further improving the assembly speed and saving time and effort.

[0033] See also Figure 1-3 In order to conveniently complete the disassembly and assembly between the keel parts, the fixing mechanism 5 in this embodiment includes a starting component, a fixing component and a guiding component; the starting component includes a worm 501, a handle 502, a worm wheel 503 and a bidirectional screw 504, one end of which is rotatably connected to the inner rear side wall of the connection box 2 through a bearing and the other end of which passes through the outside of the secondary keel 1. The front end of the worm 501 is fixed to the handle 502, and the front and rear sides of the outer surface of the worm 501 are respectively meshed with the two worm wheels 503. The two bidirectional screws 504 are respectively fixed to the inner walls of the axes of the two worm wheels 503 and are rotatably connected between the left and right sides of the inner cavity of the connection box 2 through bearings. By rotating the handle 502, the worm 501 and the worm wheel 503 are driven to rotate, and then the bidirectional screw 504 is driven to rotate, providing a power source for the movement of the fixing component.

[0034] Among them, the front and rear sides of the outer surface of the worm 501 are fixed with threaded strips with the same spiral direction, and a connecting hole is opened on the front of the connecting box 2. The connecting hole and the worm 501 are rotationally connected, so that the worm 501 can more stably drive the two worm wheels 503 to rotate in the same direction.

[0035] At the same time, the fixing component includes two adjusting sliders 505, four connecting rods 506 and four positioning rods 507. The adjusting slider 505 is threadedly connected between the outer surfaces of the two adjusting sliders 505. The front and rear sides of the upper surface of the adjusting slider 505 are respectively fixed to the lower surfaces of the two connecting rods 506. The upper surface of the connecting rod 506 is fixed to the lower surface of the positioning rod 507. The two adjusting sliders 505 are driven to move by the rotation of the bidirectional screw 504, so that the positions of the connecting rods 506 and the positioning rods 507 can be adjusted.

[0036] In addition, four movable holes are provided on the upper surface of the connecting box 2, and the movable holes are slidably connected to the connecting rod 506, so that the movement of the connecting rod 506 is more stable. The fixing mechanism 5 also includes two limiting grooves 511 provided on the left and right sides of the main keel 3. The limiting grooves 511 are slidably connected to the positioning rod 507, so that the positioning rod 507 can pass through the limiting grooves 511 more accurately and then be fixed to the main keel 3.

[0037] In addition, the guide assembly includes two T-shaped grooves 509 opened on the front and rear sides of the inner cavity of the connecting box 2, four T-shaped sliders 510 and two fixed seats 508 fixed on the upper surface of the connecting box 2. The inner wall of the T-shaped groove 509 is slidably connected with the T-shaped slider 510. The opposite sides of the two T-shaped sliders 510 are respectively fixed to the front and rear sides of the adjusting slider 505. Two connecting holes are opened on the fixed seat 508. The two connecting holes are respectively slidably connected to the two positioning rods 507. When the adjusting slider 505 moves, the T-shaped slider 510 is driven to move along the T-shaped groove 509, so that the adjusting slider 505 can maintain a relatively stable state to move without self-rotation, and can more stably drive the connecting rod 506 and the positioning rod 507 to move.

[0038] In this embodiment, the starting component provides power to the fixing component and cooperates with the guiding component to conveniently fix or disassemble the secondary keel 1 and the main keel 3.

[0039] It should be noted that the working principle of the above embodiment is:

[0040] During installation, by moving the fixing seat 508 along the main keel 3, the connection box 2 and the main keel 3 can be moved in contact with each other, thereby driving the secondary keel 1 to move until the secondary keel 1 is moved to a suitable position. At this time, the handle 502 can be turned to drive the worm 501 to rotate. The rotation of the worm 501 drives the two worm wheels 503 to rotate through the meshing force. Since the front and rear sides of the outer surface of the worm 501 are fixed with thread strips with the same spiral direction, the two worm wheels 503 can rotate in the same direction, thereby driving the two bidirectional screws 504 to rotate in the same direction, thereby prompting the two adjusting sliders 505 to move relative to each other. The movement of the two adjusting sliders 505 can respectively drive the two sets of connecting rods 506 and the positioning rod 5 07 is moved. At this time, the movement of the adjusting slider 505 will drive the T-shaped slider 510 to move along the inner wall of the T-shaped slide groove 509, so that the adjusting slider 505 itself is more guided when moving, and then it can more stably drive the connecting rod 506 and the positioning rod 507 to move, until the two groups of positioning rods 507 are respectively moved into the interior of the limiting groove 511 along the connecting holes on the fixing seat 508. At this time, the position of the main keel 3 and the connecting box 2 is fixed, and then the position of the secondary keel 1 and the main keel 3 can be fixed, so that the operator does not need to use other additional tools to complete the installation of the keel parts. The installation is quick and convenient, and it is also more convenient for later installation or disassembly, which improves the assembly speed and improves work efficiency.
