Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an installation component for a ceiling lighting fixture. Background Technology

[0002] Lighting fixtures installed inside buildings generally include a mounting bracket and a lamp housing. In use, the mounting bracket is first fixed to the ceiling, and then the lamp housing is connected to the mounting bracket. To facilitate the connection between the lamp housing and the mounting bracket, a flexible snap-fit ​​structure is typically used. For example, Chinese invention patent application 201610805092.X discloses a ceiling light structure comprising: a ceiling plate, a lamp housing mounted on the ceiling plate, and a flexible snap-fit ​​module disposed on the lamp housing. The ceiling plate includes a snap-fit ​​portion disposed on the peripheral side wall of the ceiling plate that cooperates with the flexible snap-fit ​​module. During assembly of the lamp housing and the ceiling plate, the flexible snap-fit ​​module is compressed under external force to mate the lamp housing with the ceiling plate. After the lamp housing and the ceiling plate are fully assembled, the external force on the flexible snap-fit ​​module is released, and the flexible snap-fit ​​module resets under elastic force and cooperates with the snap-fit ​​portion for a fixed connection. During disassembly, people need to use both hands to push the pressing parts of the elastic buckle module inward simultaneously so that the buckle can be disengaged from the locking part, and then the lamp body can be disassembled and separated from the lamp top plate.

[0003] However, the above connection structure still has the disadvantage of being inconvenient to disassemble. People need to push with both hands to unlock and disassemble it, which is inconvenient for ceiling lights that are large or heavy.

[0004] This application is proposed in response to the shortcomings of the prior art. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing lighting fixture installation structures are not easy to disassemble, and to provide an easy-to-disassemble ceiling lighting fixture installation component.

[0006] To achieve the above-mentioned functions, the present invention provides a mounting assembly for a ceiling-mounted lighting fixture, including a fixing base and a connecting base detachably connected to the fixing base. The connecting base is disposed on the lamp body of the ceiling-mounted lighting fixture. The invention is characterized by:

[0007] The connector includes an insertion part extending from the lamp body to the fixed base. A hooking part is provided at the end of the insertion part away from the lamp body. A hooking mating surface is provided on the side of the hooking part facing the lamp body. The hooking mating surface extends outward from the insertion part in a horizontal direction.

[0008] The mounting base includes a flexible buckle that can slide horizontally. The flexible buckle has a first guide slope on the side facing the lamp body and a support surface on the side facing away from the lamp body. During installation, the hook part abuts against the first guide slope from below, pushing the flexible buckle to move horizontally to avoid it. After the hook part passes, the flexible buckle resets, and the hook mating surface and the support surface abut against each other, so that the hook part can be supported from below by the support surface.

[0009] The connector also includes a slider disposed on the insertion part. The slider can move between the hook part and the lamp body along the extension direction of the insertion part. A second guide slope is provided on the side of the slider facing the lamp body. The distance from a point on the second guide surface to the insertion part increases as the distance to the lamp body increases.

[0010] Furthermore, in the sliding direction of the elastic buckle, the maximum distance from a point on the second guide surface to the insertion part is greater than or equal to the maximum distance from a point on the hook-fitting surface to the insertion part.

[0011] Furthermore, the insertion part is rod-shaped, and a pair of elastic buckles are disposed on both sides of the insertion part. The sliding direction of the pair of elastic buckles is on the same straight line and perpendicular to the insertion part.

[0012] Furthermore, the slider is an inverted cone shape, wider at the top and narrower at the bottom, and is fitted onto the outside of the insertion part.

[0013] Furthermore, the projection of the hook-fitting surface in the extension direction of the insertion portion falls within the surface range of the slider near the fixed seat.

[0014] Furthermore, the insertion part is provided with a thread at one end near the fixed base, and the hook part is truncated cone-shaped and threadedly connected to the insertion part.

[0015] Furthermore, the middle portion of the hook-fitting surface forms a recess towards the fixed seat, and the slider is provided with a protrusion matching the shape of the recess on the side facing the fixed seat. When the slider and the hook-fitting surface abut, the protrusion is inserted into the recess to form a positioning fit.

[0016] Furthermore, the mounting assembly also includes a mounting bracket, which is fixedly mounted on the mounting base, and the fixing seat is disposed on the mounting bracket.

[0017] Furthermore, the mounting bracket is also provided with a hanging bracket, the lamp body is provided with a hanging plate that cooperates with the hanging bracket, and a connecting seat that cooperates with the fixing seat. The hanging plate and the connecting seat are respectively located on both sides of the center of gravity of the lamp body.

[0018] This application also provides a ceiling lighting fixture, including the mounting components described above.

[0019] The ceiling lighting fixture installation assembly provided in this application can quickly connect and disconnect the light fixture and the mounting bracket, making it convenient for light fixture installation and easy for replacement and maintenance. Attached Figure Description

[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the mounting components and the ceiling-mounted lighting fixture proposed in this utility model.

[0030] In a preferred embodiment of this application, the lighting fixture is a ceiling light, such as... Figure 1 , Figure 2 , Figure 3 As shown. The embodiment of the lamp includes a lamp body 5 and a mounting assembly.

[0031] The lamp body 5 is similar to that of a conventional ceiling light, including a base 501, a frame 502, and a cover 503. The base 501, frame 502, and cover 503 together form the lamp body 5 of the lighting fixture, and its interior constitutes an accommodating space in which the power supply assembly 6 and the light source module 7 are housed. The light source module 7 emits light towards the cover 503, and the emitted light passes through the cover 503 and exits from the lamp body 5 to achieve the lighting function.

[0032] The mounting components include a mounting bracket 1 fixedly installed on a mounting base. In this embodiment, the light fixture is a ceiling light, and the mounting base is the top surface of the building, which can be a roof, ceiling, suspended ceiling, etc. Two sets of connecting structures are respectively provided on opposite sides of the mounting bracket 1. One side of the mounting bracket 1 is bent downwards and inwards to form a hanging bracket 101, and a mounting plate 4 that cooperates with it is provided on the light body 5. A fixing seat 2 as proposed in this application is provided on the other side of the mounting bracket 1, and a connecting seat 3 that cooperates with the fixing seat 2 is provided on the light body 5. The hanging plate 4 and the connecting seat 3 are respectively located on both sides of the center of gravity of the light body 5. Through these two sets of connecting structures, the light body 5 and the mounting bracket 1 are reliably connected, thereby completing the installation of the light fixture.

[0033] The structure of connector 3 is as follows Figure 6 , Figure 7As shown, the connecting base 3 includes a base 304 connected to the lamp body 5, an insertion part 302 extending upward from the base 304, a slider 303 sleeved on the insertion part 302, and a hanging part 301 disposed at the top of the insertion part 302. The hanging part 301 has a hanging mating surface 3011 on the side facing the lamp body 5. In this embodiment, the lamp is a ceiling lamp. The base 304 is disposed on the side of the base 501 of the lamp body 5 facing the mounting base. When connected to the fixing base 2, the insertion part 302 is inserted into the fixing base 2 from bottom to top. In this embodiment, the insertion part 302 is rod-shaped, and the slider 303 is sleeved on the outside of the rod-shaped insertion part 302 and can slide up and down along the rod. In other preferred embodiments, a groove can also be provided in the extending direction of the insertion part 302, and the slider 303 and the groove cooperate to achieve movement. In the moving direction of the slider 303, the lower part is limited by the base 304, and the upper part is the hanging part 301. One end of the insertion part 302 is connected to the base 304, and the other end is provided with a thread 3021. The hook part 301 and the insertion part 302 are threadedly connected. During installation, the insertion part 301 is first passed through the slider 303, and then the hook part 301 and the insertion part 302 are fixed by threaded connection. In other preferred embodiments, the hook part 301 and the insertion part 302 can also be set as an integral component, and the insertion part 302 and the base 304 are threadedly connected, thereby realizing the installation of the slider 303. The slider 303 is an inverted cone shape with a larger top and a smaller bottom. The cone surface near the lamp body 5 is set as the second guide slope 3031. Since it is an inverted cone shape, the closer a point on the second guide slope 3031 is to the lamp body 5, the smaller its distance from the insertion part 302. That is, the distance from a point on the second guide slope 3031 to the insertion part 302 increases as the distance from that point to the lamp body 5 increases. The slider 303 is also provided with a protrusion 3032 facing the hook-up portion 301. The hook-up mating surface 3011 of the hook-up portion 301 is a plane extending horizontally outward with the insertion portion 302 as the center. The hook-up mating surface 3011 is recessed into the body of the hook-up portion 301 in the direction of the fixing seat to form a recess 3012. The recess 3012 and the protrusion 3032 are adapted to each other. When the slider 303 slides upward and abuts against the hook-up portion 301, the protrusion 3032 inserts into the recess 3012 to form a positioning fit.

[0034] The structure of the fixed base 2 is as follows Figure 4 , Figure 5As shown, the fixing base 2 includes a housing 201 and a cover plate 202. A through hole 205 is provided in the middle of the cover plate 202, through which the hook part 301 and the insertion part 302 of the connecting base 3 can be inserted. The inner cavity of the housing 201 is provided with a slide guide groove 206 for placing elastic buckles 203. The cover plate 202 is locked onto the housing 201 by screws, closing the opening of the slide guide groove 206. A pair of elastic buckles 203 are provided inside the housing 201. Each elastic buckle 203 includes a claw 2031 and a spring 2032. The claw 2031 can slide horizontally in the slide guide groove 206. The two claws 2031 are arranged opposite each other, and their sliding direction is on the same straight line. When the insertion part 302 of the connecting base 3 is inserted into the fixing base 2, the two elastic buckles 203 are located on both sides of the insertion part 302, and the sliding direction of the claws 2031 is perpendicular to the axis of the insertion part 302. One end of the spring 2032 abuts against the head of the claw 2031, and the other end abuts against the inner wall of the housing 201. The head of the claw 2031 has a first guide slope 20311 facing the lamp body 5, and a support surface 20312 facing away from the lamp body 5. Since the lamp is a ceiling light, the mounting bracket 1 is located on the roof, and the lamp body 5 is located below the mounting bracket 1. Therefore, the upper surface of the head of the claw 2031 is the support surface 20312, which is a flat surface. Its lower surface is the first guide slope 20311, which slopes towards the center. During installation, after the hook-on part 301 is inserted through the through hole 205, the hook-on part 301 contacts the elastic buckle 203. The hook-on part 301 abuts against the first guide slope 20311 from below, pushing the claw 2031 to move horizontally to avoid it. After the hook-on part 301 passes through, the spring 2032 pushes the claw 2031 to return to its original position. At this time, the support surface 20312 of the claw extends into the lower part of the hook-on part 301, providing support for the hook-on mating surface 3011. The housing 201 also includes a receiving cavity 204. When the elastic buckle 203 and the hook-on part 301 form a snap-fit ​​engagement, the hook-on part 301 is accommodated within the receiving cavity 204. In this embodiment, the hook part 301 is truncated cone-shaped, with its bottom surface being the hook mating surface 3011 and its side surface being the third guide slope 3013. The third guide slope 3013 and the first guide slope 20311 have the same inclination direction and angle, making the entire upward pushing process smoother.

[0035] In this embodiment, the fixing seat 2 and the connecting seat 3 can not only be quickly connected, but also quickly disconnected. When installing the lamp, align the connecting seat 3 with the through hole 205 on the cover plate 202 of the fixing seat 2, and push the lamp upward. The hanging part 301 will press against the first guide slope 20311 of the claw 2031, causing it to move to both sides under force. The slider 303 set in the insertion part 302 falls downward due to gravity and will not contact the elastic buckle 203. When the bottom of the hanging part 301 is higher than the upper surface of the claw 2031, the claw 2031 moves towards the center under the action of the spring 2032 until the claw 2031 abuts against the limiting step 207. Stop pushing upward, and the lamp falls back under gravity. At this time, the bottom hanging mating surface 3011 of the hanging part 301 will fall back to the support surface 20312 of the upper surface of the claw 2031, forming a lock. Figure 8 As shown.

[0036] When separation is required, push the lamp upward again. At this time, the slider 303 will press against the first guide slope 20311 of the clasp 2031, causing it to move to both sides again until the two separate. The slider 303 enters the receiving cavity 204, and the clasp 2031 moves towards the center under the action of the spring 2032. Figure 9a As shown. When the lamp falls under the influence of gravity, the slider 303 contacts the mounting part 301, the protrusion 3032 inserts into the recess 3012, and the second guide slope 3031 of the slider 303 abuts against the end of the claw 2031, causing it to move to both sides under force. At this time, due to the reverse force of the claw 2031, the slider 303 and the mounting part 301 will abut together. Figure 9b Then, the hook part 301 and the slider 303 move downwards together past the elastic buckle 203 until they are completely disengaged, see... Figure 9cTo ensure that the hook-on portion 301 and the slider 303 can pass through the elastic buckle 203 together, in this embodiment, the outer contour projection of the slider 303 should not be smaller than the outer contour projection of the hook-on portion 301. Of course, in other preferred embodiments, a guide slope with the same inclination direction as the second guide slope 3031 can be provided behind the hook-on mating surface 3011 to continue pushing the claw 2031 until the hook-on portion 301 is completely disengaged. Therefore, it is only necessary to ensure that the projection of the hook-on mating surface 3011 in the extension direction of the insertion portion 203 falls within the surface range of the slider 303 near the fixing seat 2. Furthermore, in this embodiment, the protrusion 3032 on the slider 303 and the recess 3012 on the hook-on portion 301 are both located near the middle position of the insertion portion 302 and are coaxially arranged with the insertion portion 302. The advantage of this is that it prevents the slider 303 from tilting or shifting, which could cause misalignment between the top surface of the slider 303 and the bottom surface of the hook-up portion 301, preventing the hook-up portion 301 from smoothly passing downward through the elastic buckle 203. In other preferred embodiments, the hook-up portion is not necessarily a complete piece covering the end of the insertion portion 203. It can also be a protrusion extending horizontally to both sides from the insertion portion 203, with the lower surface of the protrusion serving as the hook-up mating surface. In this case, it is only necessary that the second guide surface extends beyond the protrusion in the sliding direction of the elastic buckle 203. That is, the maximum distance from a point on the second guide surface to the insertion portion must be greater than or equal to the maximum distance from a point on the hook-up mating surface to the insertion portion.

[0037] In this embodiment, the mounting bracket 1 has two connection structures. During installation, the lamp is slightly tilted to insert the mounting plate 4 into the bracket 101, such as... Figure 3 As shown. Then, push the lamp body 5 upwards, and the connecting seat 3 inserts into the through hole 205 of the fixing seat 2. A metallic clanging sound is heard, indicating that the hanging part 301 and the elastic buckle 203 have locked together. For disassembly, push the lamp body 5 upwards again (it is better to apply the pushing force to the side of the connecting seat 3), gently support the lamp body 5, and let it fall a short distance. This will separate the hanging part 301 from the elastic buckle 203, and the lamp can be removed. This method is easy to install and easy to disassemble, and can be completed by a single person.

[0038] In other preferred embodiments, the lamp can be installed using only the mounting base 2 and connecting base 3 structure provided in this application. The mounting base 2 can be directly set on the mounting foundation, and the connecting base 3 can be connected to the lamp body. This application does not limit this.

[0039] The description of the preferred embodiments of the present invention above is for illustrative purposes and is not intended to exhaustively describe or limit the present invention to the specific forms disclosed. Obviously, many modifications and variations may be made, which may be apparent to those skilled in the art and should be included within the scope of the present invention as defined by the appended claims.
