Detailed Implementation Manner

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present disclosure clearer and more understandable, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0029] It should be noted that when a component is referred to as "fixed to" or "disposed on" another component, it can be directly or indirectly located on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

The terms "first" and "second" are only used for the purpose of convenient description and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0030] In traditional construction schemes, the ceiling surface of the prefabricated soft film ceiling mostly adopts an overall luminous ceiling scheme of pasting LED light strips on the upper part of the soft film ceiling to solve the ceiling lighting problem. This scheme is suitable for use in public building ceilings or commercial office spaces.

[0031] The overall luminous ceiling scheme is not applicable to the soft film ceiling in family residences or apartment interiors, and there may be a situation where downlights or spotlights need to be installed. When encountering the situation of installing downlights or spotlights, the original traditional method was mostly to use a wooden board to custom-process a wooden box on-site as a base, place the wooden box on the prefabricated soft film ceiling and fixedly connect it to the ceiling structure, which can be used as a fixed installation base for downlights or spotlights. This scheme has various problems such as complex on-site construction, low installation efficiency, and lack of aesthetics.

[0032] To solve the technical problem of difficult installation of downlights in the soft film ceiling mentioned above, an embodiment of the present disclosure provides a downlight installation assembly, in which a clamping structure for clamping the downlight is designed inside the positioning member, and the positioning member is fixedly connected to the top wall, so that the downlight can be fixed on the positioning member.

[0033] The following will describe in detail a downlight installation assembly, a soft film ceiling system, and a method for installing a soft film ceiling system according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0034] Figure 1 is an installation schematic diagram of a downlight installation assembly provided by an embodiment of the present disclosure; Figure 2 is a structural schematic diagram of a fixing clip provided by an embodiment of the present disclosure; Figure 3 is a structural schematic diagram of a positioning member provided by an embodiment of the present disclosure; Figure 4 is a cross-sectional view of a positioning member provided by an embodiment of the present disclosure; Figure 5 is a structural schematic diagram of a downlight provided by an embodiment of the present disclosure; Figure 6 is a structural schematic diagram of an inclined tie rod provided by an embodiment of the present disclosure;

[0035] Figure 7 As shown in Figure 6 is a bottom view of the inclined tie rod shown in Figure 8 is a flow schematic diagram of a method for installing a soft film ceiling system provided by an embodiment of the present disclosure. The following will refer to Figures 1 to 8 and describe in detail the technical solutions of the embodiments of the present disclosure in combination with the embodiments.

[0036] As shown in Figure 1 An embodiment of the present disclosure provides a downlight installation assembly, including: a suspension rod 110, the lower end of the suspension rod is provided with a first thread, and the upper end of the suspension rod can be connected to the top wall; a fixing clip 120, the fixing clip includes a hoisting part that bulges upward and bends into an inverted U shape and first horizontal connecting parts with the same horizontal height respectively located at two lower ends of the hoisting part. A first through hole is provided at the bottom of the inverted U shape of the hoisting part. The lower end of the suspension rod passes through the first through hole and is fixedly connected to the bottom of the inverted U shape through the first thread and a first nut adapted to the first thread. Among them, the first nut includes a fixing nut 171; a positioning member 130, including an annular clamping plate, an annular supporting plate formed by vertically bending downward and extending from the inner edge of the annular clamping plate, and mounting columns arranged on both sides of the annular clamping plate along the diameter direction. Threaded holes are provided in the mounting columns, and each mounting column is correspondingly connected to a first horizontal connecting part through a screwing member passing through the threaded hole; when the back of the downlight 140 is inserted into the accommodation space between the fixing clip and the positioning member, the retaining spring of the downlight can be clamped on the annular clamping plate, and the light-emitting part of the downlight is located below the opening of the decorative film of the soft film ceiling 300.

[0037] The downlight in the embodiments of the present disclosure can be a downlight or a spotlight. When the downlight is installed on a soft film ceiling by adopting the technical solution of the embodiments of the present disclosure, the installation is quick, the installation is firm, and the positioning height of the lamp can be quickly adjusted, thereby solving the technical problem of difficult installation when installing a downlight on a soft film ceiling.

[0038] As Figure 2 shown, the fixing clip includes a hanging part 121 that bulges upward and bends into an inverted U shape, and first horizontal connecting parts 122 with the same horizontal height located at the two lower ends of the hanging part respectively. A first through hole is provided on the bottom of the inverted U shape of the hanging part. In addition, an internally threaded column 123 is provided above the top of the fixing clip. The internally threaded column 123 has an internally threaded hole communicating with the first through hole, and the suspension rod can pass through the internally threaded column. As Figure 2 shown, the hanging part can be a semi-circular left-right symmetric structure, and the two first horizontal connecting parts are symmetrically arranged on both sides of the hanging part.

[0039] As Figure 3 and Figure 4 shown, the positioning member includes an annular clamping plate 131, an annular supporting plate 132, and two mounting posts 133 located on both sides of the annular clamping plate. As Figure 3 shown, the annular clamping plate is an annular disc structure. The disc part plays a role in connecting the fixing clip, and the middle round hole is used to pass through the back of the downlight. The distances from the mounting posts to the inner edge and the outer edge of the annular clamping plate are equal, so that the positioning member can be stably hoisted and sufficient space is reserved for the clamping spring of the downlight.

[0040] The mounting posts 133 are correspondingly arranged with the two first horizontal connecting parts of the fixing clip. Mounting holes corresponding to the positions of the mounting posts 133 are provided at the corresponding positions of the first horizontal connecting parts. Screws pass through the mounting holes and the mounting posts and are screwed with nuts, thereby realizing the fixed connection between the fixing clip and the positioning member.

[0041] As Figure 5 shown, the downlight 140 includes a back 141, a light-emitting part 142, and a clamping spring 143. As Figure 1 shown, the inner diameter of the annular clamping plate is larger than the diameter of the back of the downlight and smaller than the diameter of the light-emitting part of the downlight. This design enables the back of the downlight to be clamped into the accommodating space of the positioning member, and the light-emitting part of the downlight cannot be clamped into the accommodating space of the positioning member, thus facilitating installation.

[0042] As Figure 1 shown, in the embodiments of the present disclosure, the downlight installation assembly further includes an expansion bolt 150. The expansion bolt is fixedly connected to the upper end of the suspension rod 110, and the expansion bolt 150 can be fixedly connected to the top wall 200, thereby fixedly connecting the suspension rod 110 to the top wall 200.

[0043] AsFigure 1 As shown, in the embodiment of the present disclosure, the lower surface of the annular support plate is flush with the soft film ceiling. The lower surface of the annular support plate is the lower surface of the positioning member. As Figure 1 shown, the lower surface of the positioning member can be flush with the soft film ceiling, facilitating the flat installation of the downlight. In addition, the lower surface of the positioning member can be higher or lower than the soft film ceiling, facilitating the adjustment of the installation height of the downlight.

[0044] As Figure 1 shown, the lower end of the suspension rod passes through the bottom of the inverted U-shape of the fixed clamp, and the first horizontal connecting portion of the fixed clamp and the mounting post of the positioning member are fixedly connected by screws and nuts.

[0045] As Figure 6 and Figure 7 shown, the downlight installation assembly further includes an inclined tie rod 160. The inclined tie rod includes a second horizontal connecting portion 601 with a second perforation 604 extending horizontally, an inclined portion 602 extending obliquely upward to the upper right from the second horizontal connecting portion, and a third horizontal connecting portion 603 extending horizontally from the upper end of the inclined portion; the suspension rod passes through the second perforation and is fixedly connected to the third horizontal connecting portion by a second nut. Among them, the first position of the suspension rod is fixedly connected to the second horizontal connecting portion, a second thread adapted to the second nut is provided at the first position of the suspension rod, and the third horizontal connecting portion is fixedly connected to the top wall by a screwing member. The second nut includes a fixing nut 172. The second thread may have the same thread structure as the first thread. The screwing member may be a screw 181, and is not limited thereto.

[0046] As Figure 6 shown, the inclined tie rod is designed as a Z shape. The second horizontal connecting portion 601 and the third horizontal connecting portion 602 are respectively the two ends of the Z-shaped structure, and the suspension rod passes through the second perforation 604 on the second horizontal connecting portion. Mounting holes may also be provided on the third horizontal connecting portion. As Figure 1 shown, the screw 181 as shown can pass through the mounting hole to fix the inclined tie rod on the top wall 200.

[0047] As Figure 1 shown, the downlight installation assembly further includes an expansion bolt 150. The expansion bolt is fixedly connected to the upper end of the suspension rod, and the expansion bolt can be fixedly connected to the top wall.

[0048] In the embodiment of the present disclosure, the outer surface of the suspension rod may be covered with continuous first threads. The suspension rod may be a hanger screw rod.

[0049] In the embodiment of the present disclosure, the suspension rod is inserted into the internal threaded column of the fixing clip and fixedly connected to the fixing clip through a fixing nut. The positioning member and the fixing clip can be fixed as a whole through screws and nuts. In the embodiment of the present disclosure, the expansion bolt can be drilled and fixed on the ceiling structural floor according to the drawing and the position of the lamp, and the upper end of the suspension rod is fixed in the expansion bolt. The second through hole of the second horizontal connecting portion of the diagonal tie rod is inserted through the suspension rod, and two fixing nuts 171 located above and below the second horizontal connecting portion are used for fixing and clamping, and the other end is fixed on the ceiling structural floor with a screw 181, so that the diagonal tie rod and the suspension rod form a triangular structure to ensure the installation stability of the suspension rod. The overall structure after fixing the positioning member and the fixing clip as a whole is rotationally installed at the lower end of the suspension rod through the internal threaded column, and the lower end of the overall structure is flush with the height of the soft film ceiling. Then, a fixing nut 172 is used below the fixing clip to fixedly connect the fixing clip and the suspension rod. After that, the position of the positioning member is adjusted to be consistent with the position of the pre-installed downlight. An opening is dug at the position of the pre-installed downlight on the soft film ceiling, and the diameter of the opening is the same as the diameter of the annular support plate of the positioning member. Then, the back of the downlight is passed through the opening dug on the soft film ceiling, and the retaining spring 143 of the downlight is lapped on the upper end surface of the annular clamping plate of the positioning member, so that the light-emitting part of the downlight is in close contact with the soft film ceiling, completing the installation of the entire lamp.

[0050] In the embodiment of the present disclosure, the distance between the lower end of the back of the downlight and the lower end of the retaining spring of the downlight is equal to the height of the annular support plate. The distance between the lower end of the back of the downlight and the lower end of the retaining spring of the downlight can also be slightly less than the height of the annular support plate. This distance being equal to or less than the height of the annular support plate is beneficial to the clamping of the retaining spring and the annular clamping plate, and thus beneficial to the installation stability of the downlight.

[0051] The downlight installation assembly provided by the embodiment of the present disclosure can provide an installation space for the downlight by designing the fixing clip and the positioning member. Among them, the fixing clip can connect the suspension rod and the positioning member, and the upper end of the suspension rod is connected to the top wall, realizing the fixed connection between the positioning member and the top wall. The annular clamping plate of the positioning member can be clamped with the retaining spring of the downlight, realizing the fixed connection between the downlight and the positioning member, so that the downlight can be simply and stably installed on the top wall with a soft film ceiling.

[0053] Specifically, the material of the suspension rod can be galvanized steel wire, steel bar, or galvanized low-carbon annealed steel wire, and the suspension rod should be directly connected to the stress-bearing part of the room top structure.

[0054] In the embodiment of the present disclosure, the upper surface of the light-emitting part of the downlight is flush with the soft film ceiling, so as to ensure the flatness and stability of the downlight installation.

[0055] In the soft film ceiling system provided by the embodiment of the present disclosure, the downlight installation component can provide an installation space for the downlight by designing a fixed clip and a positioning member. Among them, the fixed clip can connect the suspension rod and the positioning member, and the upper end of the suspension rod is connected to the top wall, realizing the fixed connection between the positioning member and the top wall. The annular clamping plate of the positioning member can be clamped with the retaining spring of the downlight, realizing the fixed connection between the downlight and the positioning member, so that the downlight can be simply and stably installed on the top wall where the soft film ceiling is installed.

[0056] Figure 8 is a schematic flow chart of the installation method of the soft film ceiling system provided by the embodiment of the present disclosure. As Figure 8 shown, an embodiment of the present disclosure provides an installation method for the soft film ceiling system in the above technical solution, and the installation method includes:

[0057] Step S801, fixedly install the downlight installation component on the top wall through the suspension rod, and expose the lower surface of the annular support plate of the downlight installation component in the opening of the decorative film of the soft film ceiling.
