Description

Technical Field

[0001] The present invention relates to the technical field of suspended ceiling decoration and furnishing, and in particular to a suspended ceiling. Background Art

[0002] A suspended ceiling is a type of decoration that is placed on top of a house. Simply put, it refers to the ceiling decoration, and is an important part of interior decoration. It is widely used in interior decoration and features quick installation, easy assembly and disassembly, and a variety of decorative styles that are easily changeable.

[0003] In some existing ceilings, the top space of the ceiling is dark and closed. When entering the ceiling for maintenance, lighting is required to ensure the safety of the construction workers. Usually, maintenance workers enter the ceiling with maintenance tools and lighting at the same time. However, when both hands are holding the tools needed for work, it creates certain safety hazards for maintenance workers to climb into the ceiling. In addition, the space at the top of the ceiling also contains messy wire harnesses. When there is not enough lighting environment, the construction workers may accidentally trip during construction, thereby posing a safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the existing technology and propose a ceiling suspended ceiling, which is used to solve the problem that when it is necessary to enter the ceiling suspended ceiling for maintenance, lighting is required to ensure the safety of construction personnel. Usually, maintenance personnel enter the ceiling suspended ceiling with maintenance tools and lighting at the same time, but when both hands hold the tools needed for work, it creates certain safety hazards for maintenance personnel to climb into the suspended ceiling. In addition, the space at the top of the suspended ceiling also contains messy wiring harnesses. When there is no sufficient lighting environment, the construction personnel may accidentally trip during construction, thereby causing safety hazards.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A ceiling comprises: two main purlins and four expansion screws, the two main purlins are relatively installed on the walls on both sides, the four expansion screws are in groups of two, and the two groups of expansion screws are respectively screwed through the two main purlins and fixed to the walls, a number of secondary purlins are fixed horizontally between the two main purlins, a baffle is installed between every two secondary purlins, the baffle is composed of a first top plate and a second top plate, a rotating assembly for driving the second top plate to rotate toward the roof is installed between the first top plate and the second top plate, a ceiling assembly for hanging the entire baffle is also provided on the upper surface of the first top plate, a lighting assembly for improving the brightness of the construction environment is installed on the ceiling assembly, and a guide rail assembly for arranging the wiring harness above the baffle is also installed on the upper surfaces of the first top plate and the second top plate.

[0007] Working principle:

[0008] When construction and maintenance personnel need to enter the top of the suspended ceiling for maintenance, the maintenance personnel first push the second top plate toward the upper surface of the baffle plate through external support until the second top plate rotates to above the first top plate. At this time, during the rotation of the second top plate, the second top plate drives the guide rail assembly to rotate at a certain angle. At this time, the guide rail assembly binds and organizes the wire harness on the upper surface of the baffle plate. At the same time, when the second top plate rotates to abut against the suspended ceiling assembly, the lighting assembly on the suspended ceiling assembly can provide sufficient lighting for the maintenance personnel entering the suspended ceiling. The set suspended ceiling assembly can bear the support weight for the maintenance personnel.

[0009] The beneficial effects of the present invention are:

[0010] Compared with the existing technology, when the maintenance personnel enter the top of the baffle for maintenance, the maintenance personnel first push the second top plate toward the upper surface of the baffle through external support until the second top plate rotates to above the first top plate. At this time, during the rotation of the second top plate, the second top plate drives the guide rail assembly to rotate at a certain angle. At this time, the guide rail assembly binds and organizes the wire harness on the upper surface of the baffle. At the same time, when the second top plate rotates to abut against the ceiling assembly, the lighting assembly on the ceiling assembly can provide sufficient lighting for the maintenance personnel entering the ceiling. The set ceiling assembly can bear the support weight for the maintenance personnel. At this time, the maintenance personnel can safely enter the top of the baffle. Before entering the upper surface of the baffle, the lighting inside the ceiling can be supplied in time. The guide rail assembly can timely organize the wire harness on the upper surface of the baffle to prevent the maintenance personnel from tripping due to insufficient lighting and unorganized wire harnesses when entering the ceiling, thereby reducing safety hazards during maintenance.

When the connecting rod 31 rotates, it drives the wire harness on the upper surface of the baffle 3 to be bound and sorted.

[0020] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the guide rail assembly includes a telescopic spring 20 with hooks at both ends, two loop hooks 21 and two limit covers 22, the first top plate 4 and the second top plate 5 are both provided with a slide groove 32, one of the loop hooks 21 is provided on the inner side wall of the slide groove 32 on the first top plate 4 and on the side away from the second top plate 5, and another loop hook 21 is provided on the inner side wall of the slide groove 32 on the second top plate 5 and on the side away from the first top plate 4. The two ends of the telescopic spring 20 are respectively hooked on the two loop hooks 21, and two card slots 23 are respectively provided on both sides of the two slide grooves 32. The two limit covers 22 are respectively fixedly installed in the card slots 23, and also include a wiring harness plate 24, which is provided on the second top plate 5 and close to the side of the first top plate 4. The wiring harness plate 24 is provided with a plurality of wiring harness holes 25 for different types of wiring harnesses to pass through, and also includes a bar 26, Hole 27, an extrusion spring 28 is installed on the inner wall of the limiting hole 27, and an arc-shaped extrusion plate 29 is installed on the extrusion spring 28. The extrusion plate 29 passes through the wiring harness between the bottom of the limiting hole 27; the second top plate 5 is provided with two slide rails 30, and the lower surface of the bar 26 has two sliders 33, and the slider 33 is slidably installed on the two slide rails 30. One end of the bar 26 is provided with a connecting rod 31, and the connecting rod 31 is connected to the second top plate. 5 is fixedly connected and used to drive the bar 26 to move on the slide rail 30, and also includes a fixed seat 35, a pull rod 36, a limit hook 37 and a limit ring 38. The fixed seat 35 is provided at the bottom of the support column 6, one end of the pull rod 36 is hinged to the fixed seat 35, the limit hook 37 is fixedly installed on the other end of the pull rod 36, and the limit ring 38 is provided on the upper surface of the second top plate 5 and is used for the cooperation of the limit hook 37 and the limit ring 38 when the second top plate 5 rotates.

[0021] When it is necessary to enter the interior of the ceiling, the second top plate 5 rotates, and the second top plate 5 drives the telescopic spring 20 located in the slide groove 32 of the second top plate 5. At this time, during the rotation of the second top plate 5, the telescopic spring 20 is stretched and moved, and the ring hook 21 drives the connecting rod 31 to rotate at the same time, and the connecting rod 31 drives the bar 26 to rotate, and the bar 26 drives the slider 33 to move in the slide rail 30. At the same time, the wiring harness on the shielding plate 3 is squeezed by the extrusion plate 29 located in the bar 26, and the bar 26 drives several wiring harnesses to move at the same time, and when the second top plate 5 abuts against the self-resetting switch 13 on the support column 6, the maintenance personnel need to hook the limit hook 37 on the pull rod 36 with the limit ring 38 on the upper surface of the second top plate 5 to limit the second top plate 5.

[0022] Working principle:

[0023] When the second top plate 5 is rotated, the two extension blocks 17 are respectively driven by the rotating rod 18 to rotate in the two grooves 19, and the two extension blocks 17 drive the second top plate 5 to rotate until the second top plate 5 abuts the self-resetting switch 13 on the support column 6. The self-resetting switch 13 is electrically connected to the emergency light 14, so that the space inside the ceiling can be illuminated. In this way, the maintenance personnel who enter the ceiling do not need to hold the lighting assembly in their hands when entering the ceiling to reduce the risk of climbing into the ceiling, and can reduce the weight of the tools brought by the operators. When the second top plate 5 rotates, it can drive the guide rail assembly to rotate. When the guide rail assembly rotates, it drives the wire harness on the upper surface of the baffle 3 to be bound and sorted.

[0024] When it is necessary to enter the interior of the ceiling, the second top plate 5 rotates, and the second top plate 5 drives the telescopic spring 20 located in the slide groove 32 of the second top plate 5. During the rotation of the second top plate 5, the second top plate 5 drives the telescopic spring 20 to stretch and move. At this time, the loop hook 21 drives the connecting rod 31 to rotate at the same time, and the connecting rod 31 drives the bar 26 to rotate. The bar 26 drives the slider 33 to move in the slide rail 30. At the same time, the wire harness on the shielding plate 3 is squeezed by the squeezing plate 29 located in the bar 26, and the bar 26 drives several wire harnesses to move at the same time, and When the second top plate 5 abuts against the self-resetting switch 13 on the support column 6, the wiring harness located on the upper surface of the baffle plate 3 can be restrained in this way, so that maintenance personnel will not be tripped by the tangled wiring harness when entering the baffle plate 3 for maintenance, causing safety hazards. At this time, the maintenance personnel need to hook the limit hook 37 on the pull rod 36 with the limit ring 38 on the upper surface of the second top plate 5 to limit the second top plate 5. This limiting method can prevent maintenance personnel from being trapped in the ceiling during maintenance due to the lack of limit when conducting maintenance on the ceiling.
