Technical Field

[0001] This utility model relates to a quick-connect structure for a lamp and a lamp, belonging to the field of lighting technology. Background Technology

[0002] Most luminaires on the market that use a rotary quick-connect method employ hooks for this connection. However, the load-bearing capacity of hooks is limited, so manufacturers often add reinforcing components to increase their load capacity. However, adding reinforcing components may compromise the luminaire's seal, and after installation, the reinforcing components may warp and detach, leading to difficulties in quick-connect assembly.

[0003] In view of this, it is indeed necessary to improve the existing quick-connect structure of lighting fixtures in order to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect structure for lighting fixtures that not only has a strong quick-connect load capacity but also enables sealed assembly of the lighting fixtures.

[0005] To achieve the above objectives, this utility model provides a quick-connect structure for lighting fixtures, comprising:

[0006] The connecting base and the chassis are provided, and the connecting base is provided with at least two hooks with snap-fit ​​parts;

[0007] The reinforcing member is assembled on the outer wall of the lug. The reinforcing member is provided with a claw and a fixing part. The fixing part is used to fix the connecting seat and the chassis, and the claw is inserted into the locking part.

[0008] The mounting base is configured to be fixedly connected to the installation base. The mounting base has a corresponding number of limiting slots. The hanging ear is configured to slide into the limiting slot along the circumference of the mounting base to limit the claw between the mounting base and the connecting base.

[0009] As a further improvement of this utility model, the snap-fit ​​part is located on the side of the hook facing the fixed seat, and the outer wall of the connecting seat is provided with a groove that communicates with the snap-fit ​​part, and the reinforcing member is accommodated in the groove.

[0010] As a further improvement of this utility model, the reinforcing member includes a first snap-fit ​​portion, a second snap-fit ​​portion parallel to it, and a connecting portion connecting the two, with a claw located at the end of the first snap-fit ​​portion.

[0011] As a further improvement of this utility model, the fixing part and the first snap-fit ​​part extend in opposite directions, and the fixing part is provided with a mounting hole for fasteners to pass through.

[0012] As a further improvement of this utility model, the outer peripheral edge of the connecting seat is provided with a relief groove that is adapted to the fixing part. The bottom wall of the relief groove is provided with a mating hole that aligns with the mounting hole. The fastener passes through the mounting hole and the mating hole to fix the reinforcing member to the connecting seat.

[0013] Another objective of this utility model is to provide a lamp having the above-mentioned quick-connect structure.

[0014] To achieve the above objectives, this utility model provides a lamp, comprising:

[0015] The above-mentioned quick-connect structure for lighting fixtures;

[0016] The mask is arranged around the outside of the connecting seat and the chassis, and the mask has a receiving cavity in which the connecting seat and the chassis are at least partially housed.

[0017] As a further improvement of this utility model, the chassis is mounted on the side of the connecting seat opposite to the fixed seat and is fixedly connected to the connecting seat by fasteners.

[0018] As a further improvement of this utility model, a wire locking device is installed on the chassis for the suspension wire to pass through. The wire locking device passes through the chassis and the face mask, forming a closed cavity between the chassis and the connecting seat. One end of the suspension wire is contained in the closed cavity, and the other end extends out of the face mask from the wire locking device.

[0019] As a further improvement of this utility model, the chassis is arranged around the outer periphery of the connecting seat, and the lower surface of the chassis is flush with the lower surface of the connecting seat in the axial direction of the connecting seat.

[0020] As a further improvement of this utility model, the lamp also includes a light source assembly, which is mounted on the bottom of the chassis and the connecting seat, and is housed in the receiving cavity and electrically connected to the second electrical connection part.

[0021] The beneficial effects of this utility model are as follows: The quick-connect structure of this utility model for lighting fixtures incorporates a claw and a fixing part on the reinforcing member. The fixing part secures the connecting seat and the chassis, while the corresponding locking part is provided on the hanging ear. The claw is inserted into the locking part, ensuring a tight connection between the reinforcing member and the hanging ear, preventing warping and detachment, and guaranteeing a stable connection. Furthermore, by assembling the reinforcing member onto the outer wall of the hanging ear, it can slide into the limiting groove along with the hanging ear, confining the claw between the fixing seat and the connecting seat. This not only enhances the quick-connect load capacity of the hanging ear but also preserves the sealing of the connecting seat, enabling sealed assembly of the lighting fixture.

The edge portion 24 is provided with a locking block 241 protruding toward the fixing seat 1 and cooperating with the anti-reverse buckle 151 to prevent the hanging ear 22 from accidentally sliding out of the limiting groove 12.

[0043] The reinforcing member 3 is correspondingly disposed and assembled on the outer wall of the hanging ear 22, sliding into or out of the limiting groove 12 along with the hanging ear 22 to enhance the load-bearing capacity of the hanging ear 22. Specifically, one end of the reinforcing member 3 is provided with a claw 31, and the hanging ear 22 is provided with a corresponding engaging part 221. The claw 31 is inserted into the engaging part 221, so that the reinforcing member 3 and the hanging ear 22 are tightly connected. The hanging ear 22 is configured to slide into the limiting groove 12 along the circumference of the fixing seat 1 to limit the claw 31 between the fixing seat 1 and the connecting seat 2. The engaging part 221 is preferably a hole-like structure formed on the hanging ear 22. The claw 31 and the engaging part 221 are interference fit, so that the reinforcing member 3 is not easy to fall off during the connection of the fixing seat 1 and the connecting seat 2, and is not easy to warp and fall off after the connection is stable.

[0044] The snap-fit ​​portion 221 is located on the side of the hook 22 facing the fixing seat 1. The outer wall of the connecting seat 2 is provided with a groove 25 that communicates with the snap-fit ​​portion 221. Specifically, the groove 25 extends from the outer wall of the hook 22 along the annular fixing portion 23 to the edge portion 24. The groove 25 is preferably Z-shaped. The reinforcing member 3 is accommodated in the groove 25 and will not affect the rotation of the connecting seat 2.

[0045] The reinforcing member 3 includes a first latching portion 32, a second latching portion 33 parallel to the first latching portion 32, and a connecting portion 34 connecting the first latching portion 32 and the second latching portion 33. The first latching portion 32 and the second latching portion 33 are located at both ends of the connecting portion 34 and extend in opposite directions. A claw 31 is provided at the end of the first latching portion 32. The first latching portion 32, the connecting portion 34, and the second latching portion 33 are received in the groove 25.

[0046] The reinforcing member 3 also includes a fixing part 35 connected to the second engaging part 33, which extends in the opposite direction to the first engaging part 32. Preferably, the fixing part 35 protrudes upward from the end of the second engaging part 33 and then extends horizontally to overlap with the outer peripheral edge of the connecting seat 2. Of course, in other alternative embodiments, the fixing part 35 may also extend directly horizontally from the end of the second engaging part 33; this is not a limitation.

[0047] The fixing part 35 is provided with a mounting hole 351 for fasteners (not labeled) to pass through. The outer peripheral edge of the connecting seat 2, i.e. the edge part 24, is provided with a relief groove 242 that is adapted to the fixing part 35. The bottom wall of the relief groove 242 is provided with a mating hole 243 that aligns with the mounting hole 351. The fastener passes through the mounting hole 351 and the mating hole 243 to fix the reinforcing member 3 to the connecting seat 2.

[0048] The fixing part 35 is also used to fix the connecting seat 2 and the chassis 300. The chassis 300 is fixedly connected to the connecting seat 2, and the chassis 300 is assembled on the side of the connecting seat 2 opposite to the fixing seat 1, and is fixedly connected to the connecting seat 2 by fasteners. The chassis 300 is preferably a metal disc structure, and the outer peripheral edge of the chassis 300 is provided with fixing holes 301. Fasteners pass through the mounting holes 351, mating holes 243 and fixing holes 301 in sequence to fix the reinforcing member 3, the connecting seat 2 and the chassis 300. In this embodiment, the mounting holes 351, mating holes 243 and fixing holes 301 are preferably provided in three sets. The fasteners can selectively pass through one or more sets of mounting holes 351, mating holes 243 and fixing holes 301 to meet the connection requirements. At the same time, a closed cavity 302 is formed between the chassis 300 and the connecting seat 2, which can improve the dustproof effect.

[0049] A face shield 500 is arranged around the outside of the connecting seat 2 and the chassis 300. The face shield 500 has a receiving cavity 501, within which the connecting seat 2 and the chassis 300 are at least partially housed. A wire lock 400 is mounted on the chassis 300 for the suspension wire 600 to pass through. The wire lock 400 passes through the chassis 300 and the face shield 500. One end of the suspension wire 600 is housed in the enclosed cavity 302, and the other end extends from the wire lock 400 through the face shield 500 to connect with the light source assembly 700. A transition circuit board 303 is provided in the enclosed cavity 302. The transition circuit board 303 is electrically connected to the second electrical connection part 21, and the power supply wire for the light source assembly 700 is connected to the transition circuit board 303. The enclosed cavity 302 provides for concealing the suspension wire 600 and for wire transfer. During user installation, it is not necessary to open the chassis 300 for wire management; the suspension wire 600 can be adjusted via the wire lock 400.

[0050] like Figures 9-11 As shown, this utility model also discloses a second embodiment of the lamp 100'. In this embodiment, the lamp 100' is preferably a ceiling lamp, including: the aforementioned lamp quick-connect structure 200, chassis 300', cover 500', and light source assembly 700'. The lamp 100' can also achieve stable connection and sealed assembly through the lamp quick-connect structure 200.

[0051] The quick-connect structure 200 for the lamp is the same as that in the first embodiment, and will not be described again here.

[0052] The fixing part 35 is also used to fix the connecting seat 2 and the chassis 300'. The chassis 300' is fixedly connected to the connecting seat 2, and the chassis 300' is arranged around the outer periphery of the connecting seat 2. In the axial direction of the connecting seat 2, the lower surface of the chassis 300' is flush with the lower surface of the connecting seat 2. The chassis 300' is preferably a metal structure. The inner peripheral edge of the chassis 300' is provided with fixing holes 301'. The fixing holes 301' are aligned with the mounting holes 351 and the mating holes 243, allowing fasteners to pass through and fix the reinforcing member 3, the connecting seat 2, and the chassis 300'. In this embodiment, the mounting holes 351, the mating holes 243, and the fixing holes 301' are preferably provided in three sets. Fasteners can selectively pass through one or more sets of mounting holes 351, mating holes 243, and fixing holes 301' to meet the connection requirements.

[0053] In this embodiment, the chassis 300' can be attached to the top of the reinforcing member 3 or connected to the bottom of the connecting seat 2, without any limitation.

[0054] A face mask 500' is arranged around the outside of the connecting seat 2 and the chassis 300'. The face mask 500' has a receiving cavity 501', and the connecting seat 2 and the chassis 300' are at least partially housed in the receiving cavity 501'. A light source assembly 700' is mounted on the bottom of the chassis 300' and the connecting seat 2. The light source assembly 700' is housed in the receiving cavity 501' and is electrically connected to the second electrical connection part 21.

[0055] The connecting base 2 and the chassis 300' directly form the ceiling light head. By adding a reinforcing member 3 to the outer wall of the hanging ear 22, the weight of the ceiling light head can be greatly increased. At the same time, since the reinforcing member 3 is snapped onto the outside of the connecting base 2, it will not damage the sealing of the connecting base 2, and thus will not damage the sealing of the light fixture 100'.

[0056] In summary, the quick-connect structure 200 of this utility model, by assembling the reinforcing member 3 on the outer wall of the hanging ear 22, allows it to slide into or out of the limiting groove 12 along with the hanging ear 22. This not only enhances the quick-connect load of the hanging ear 22 but also does not compromise the sealing of the connecting seat 2, enabling sealed assembly of the lamp. Furthermore, by providing the reinforcing member 3 with a claw 31 and a fixing part 35, the fixing part 35 is used to fix the connecting seat 2 and the chassis. Correspondingly, a snap-fit ​​part 221 is provided on the hanging ear 22, allowing the claw 31 to be inserted into the snap-fit ​​part 221, ensuring a tight connection between the reinforcing member 3 and the hanging ear 22, preventing warping and detachment, and guaranteeing a stable connection.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
