Description

Technical Field

[0001] This application relates to the field of lighting fixture technology, and in particular to a lamp connection structure and a lamp. Background Technology

[0002] In the existing technology, the installation of ceiling lights usually adopts a mechanical snap-fit ​​connection structure. The installation process requires first fixing the metal or plastic mounting bracket to the preset position on the ceiling with expansion bolts. Then, the light fixture body is forcibly embedded into the snap-fit ​​groove of the bracket by physical pressing. The fixing is achieved by the frictional interlocking force between the snaps. When disassembling, a reverse pulling force is required to overcome the mechanical locking effect of the snaps.

[0003] The aforementioned connection structure is not easy to install properly and is at risk of falling off. Moreover, it requires manual removal of the light fixture body, which may damage the light fixture body or the ceiling. Utility Model Content

[0004] This application provides a lamp connection structure and a lamp, which can improve the problem in the related technology that when disassembling a lamp, it is necessary to manually forcibly pull out the lamp body, which may easily damage the lamp body or the ceiling.

[0005] In a first aspect, embodiments of this application provide a lamp connection structure, including a first connector, a second connector, and two elastic members. The first connector is used to fix to the ceiling and has two holding portions spaced apart. The second connector is used to connect to the lamp body. The two elastic members are symmetrical about the central axis of the second connector, and each elastic member corresponds to one of the holding portions. The elastic member is connected to the second connector. Each elastic member includes a mating portion and an elastic abutment portion, which are spaced apart around the central axis and located on opposite sides of the holding portion. The elastic abutment portion abuts against the holding portion, so that the mating portion and the holding portion engage. Rotating the second connector relative to the first connector around the central axis causes the holding portion to move away from the mating portion and abut against the elastic abutment portion, thereby disengaging the holding portion from the mating portion.

[0006] In some embodiments, the elastic abutment includes a first part, a second part, and a third part. The second part and the third part are both disposed on the side of the first part near the holding part. One end of the second part is connected to the first part, and the other end of the second part extends in a direction close to the holding part. One end of the third part is connected to the end of the second part away from the first part, and the other end of the second part extends in a direction away from the holding part and is spaced apart from the first part. The connection portion of the second part and the third part abuts against the holding part.

[0007] In some embodiments, the elastic support portion and the mating portion are symmetrically arranged about a plane.

[0008] In some embodiments, one of the holding part and the mating part is provided with a slot, and the other of the holding part and the mating part is provided with a card, the card being accommodated in the slot, so as to realize the engaging and mating parts of the holding part.

[0009] In some embodiments, the first connector is provided with a receiving groove, and the elastic member is located within the receiving groove.

[0010] In some embodiments, the receiving groove has opposing first and second inner walls, the mating portion abuts against the first inner wall, and the elastic abutting portion abuts against the second inner wall.

[0011] In some embodiments, one of the mating portion and the first inner wall is provided with a first recess, and the other of the mating portion and the first inner wall is provided with a first protrusion, the first protrusion being accommodated within the first recess; and / or, one of the elastically abutting portion and the second inner wall is provided with a second recess, and the other of the elastically abutting portion and the second inner wall is provided with a second protrusion, the second protrusion being accommodated within the second recess.

[0012] In some embodiments, the elastic element includes a connecting portion, and the mating portion and the elastic abutment portion are respectively connected to the two ends opposite to the connecting portion.

[0013] In some embodiments, the bottom wall of the receiving groove is fitted to the connecting portion.

[0014] Secondly, embodiments of this application provide a lighting fixture, which includes the lighting fixture connection structure as described in the first aspect.

[0015] The lighting fixture connection structure provided in this application has the following advantages: Since the first connector has two retaining portions spaced apart, and the two elastic members are symmetrical about the central axis of the second connector, with each elastic member corresponding to one of the retaining portions, and connected to the second connector, each elastic member includes a mating portion and an elastic abutment portion. The mating portion and the elastic abutment portion are spaced apart around the central axis. Therefore, when installing the lighting fixture, the first connector can be fixed to the ceiling first, and then the retaining portion can be inserted between the mating portion and the elastic abutment portion, so that the mating portion and the elastic abutment portion are located on opposite sides of the retaining portion. At this time, the elastic abutment portion abuts against the retaining portion, allowing the mating portion and the retaining portion to engage, thus enabling the first connector and the second connector to be connected more easily. Furthermore, the connection between the first connector and the second connector is relatively tight and not easily detached.

[0016] Meanwhile, when disassembling the first and second connectors, simply rotate the second connector relative to the first connector around the central axis, so that the holding part moves away from the mating part and abuts against the elastic abutting part, thus disengaging the holding part from the mating part. This operation is simple and effortless, and the lamp body or ceiling is not easily damaged.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0037] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0038] In the existing technology, the installation of ceiling lights usually adopts a mechanical snap-fit ​​connection structure. The installation process requires first fixing the metal or plastic mounting bracket to the preset position on the ceiling with expansion bolts. Then, the light fixture body is forcibly embedded into the snap-fit ​​groove of the bracket by physical pressing. The fixing is achieved by the frictional interlocking force between the snaps. When disassembling, a reverse pulling force is required to overcome the mechanical locking effect of the snaps.

[0039] The aforementioned connection structure is not easy to install properly and is at risk of falling off. Moreover, it requires manual removal of the light fixture body, which may damage the light fixture body or the ceiling.

[0040] In view of this, this application provides a lamp connection structure and a lamp. Since the first connector has two holding parts, which are spaced apart, and two elastic members are symmetrical about the central axis of the second connector, with each elastic member corresponding to one of the holding parts, and the elastic members are connected to the second connector, each elastic member includes a mating part and an elastic abutting part, which are spaced apart around the central axis. Therefore, when installing the lamp, the first connector can be fixed to the ceiling first, and then the holding parts can be inserted between the mating parts and the elastic abutting parts, so that the mating parts and the elastic abutting parts are located on both sides of the holding parts. At this time, the elastic abutting parts abut against the holding parts, which allows the mating parts to engage with the holding parts, thereby making it easier to connect the first connector and the second connector. Furthermore, the connection between the first connector and the second connector is relatively tight and not easy to fall off.

[0041] Meanwhile, when disassembling the first and second connectors, simply rotate the second connector relative to the first connector around the central axis, so that the holding part moves away from the mating part and abuts against the elastic abutting part, thus disengaging the holding part from the mating part. This operation is simple and effortless, and the lamp body or ceiling is not easily damaged.

[0042] Please refer to Figures 1 to 6 In one aspect, embodiments of this application provide a lamp connection structure 100, including a first connector 10, a second connector 20 and two elastic members 30. The first connector 10 is used to fix to the ceiling and is provided with two holding parts 11, which are spaced apart.

[0043] The second connector 20 is used to connect with the lamp body. The two elastic members 30 are symmetrical about the central axis O of the second connector 20, and the elastic members 30 are provided in a one-to-one correspondence with the holding part 11. The elastic members 30 are connected to the second connector 20.

[0044] The elastic member 30 includes a mating part 31 and an elastic abutting part 32. The mating part 31 and the elastic abutting part 32 are spaced apart around the central axis O, and the mating part 31 and the elastic abutting part 32 are respectively located on both sides of the retaining part 11. The elastic abutting part 32 abuts against the retaining part 11 so that the mating part 31 and the retaining part 11 are engaged. When the second connecting member 20 is rotated relative to the first connecting member 10 around the central axis O, the retaining part 11 can move in a direction away from the mating part 31 and abut against the elastic abutting part 32, so that the retaining part 11 is disengaged from the mating part 31.

[0045] The first connector 10 can be a metal bracket or a plastic bracket, etc. The elastic element 30 can be made of metal or elastic plastic, such as a metal spring.

[0046] When installing the light fixture, the first connector 10 can be fixed to the ceiling first, and then the retaining part 11 can be inserted between the mating part 31 and the elastic abutment part 32, so that the mating part 31 and the elastic abutment part 32 are located on both sides of the retaining part 11. At this time, the elastic abutment part 32 abuts against the retaining part 11, so that the mating part 31 and the retaining part 11 can be engaged, thereby making it easier to connect the first connector 10 and the second connector 20.

[0047] When disassembling the first connector 10 and the second connector 20, the second connector 20 can be rotated relative to the first connector 10 around the central axis O in the direction indicated by arrow K in the figure. The holding part 11 moves away from the mating part 31 and abuts against the elastic abutting part 32. The holding part 11 and the elastic abutting part 32 continue to move away from the mating part 31 until the mating part 31 releases its abutment against the holding part 11, so that the holding part 11 and the mating part 31 are disconnected. Then the first connector 10 and the second connector 20 can be disassembled, and the separation of the lamp body and the first connector 10 can be completed.

[0048] The lamp connection structure 100 provided in this embodiment has two retaining portions 11 on the first connector 10, which are spaced apart. Two elastic members 30 are symmetrical about the central axis O of the second connector 20, with each elastic member 30 corresponding to one of the retaining portions 11. The elastic members 30 are connected to the second connector 20, and each elastic member 30 includes a mating portion 31 and an elastic abutment portion 32, which are spaced apart around the central axis O. Therefore, when installing a lamp, it is possible to... First, fix the first connector 10 to the ceiling, then insert the retaining part 11 between the mating part 31 and the elastic abutment part 32, so that the mating part 31 and the elastic abutment part 32 are located on both sides of the retaining part 11. At this time, the elastic abutment part 32 abuts against the retaining part 11, so that the mating part 31 and the retaining part 11 can be engaged, thereby making it easier to connect the first connector 10 and the second connector 20. The connection between the first connector 10 and the second connector 20 is relatively tight and not easy to fall off.

[0049] Meanwhile, when disassembling the first connector 10 and the second connector 20, simply rotate the second connector 20 relative to the first connector 10 around the central axis O, so that the holding part 11 moves away from the mating part 31 and abuts against the elastic abutting part 32, so that the holding part 11 can be disengaged from the mating part 31. The operation is simple and labor-saving, and the lamp body or ceiling is not easily damaged.

[0050] Please refer to Figures 2 to 6 In this embodiment, the elastic abutment 32 includes a first part 321, a second part 322, and a third part 323. The second part 322 and the third part 323 are both disposed on the side of the first part 321 near the holding part 11. One end of the second part 322 is connected to the first part 321, and the other end of the second part 322 extends toward the holding part 11. One end of the third part 323 is connected to the end of the second part 322 away from the first part 321, and the other end of the second part 322 extends away from the holding part 11 and is spaced apart from the first part 321. The connection part of the second part 322 and the third part 323 abuts against the holding part 11.

[0051] By adopting the above solution, the structure of the elastic support part 32 can be made simpler, and it can provide sufficient support force with the holding part 11.

[0052] It should be noted that the first part 321, the second part 322, and the third part 323 can be integrally molded. The elastic force of the second part 322 and the third part 323 can be used to lock and hold the retaining part 11 in place.

[0053] Optionally, the elastic support portion 32 and the mating portion 31 are symmetrically arranged about a plane.

[0054] This design simplifies the structure of the elastic element 30, making it easier to manufacture.

[0055] Optionally, one of the holding part 11 and the mating part 31 is provided with a slot 111, and the other of the holding part 11 and the mating part 31 is provided with a locking element 311. The locking element 311 is housed in the slot 111 so as to realize the locking and mating of the mating part 31 and the holding part 11.

[0056] This design ensures that the mating part 31 and the retaining part 11 are tightly connected when they are engaged, and they will not easily fall off.

[0057] It is understood that the mating part 31 may also include a first part 321, a second part 322 and a third part 323, with the connecting part of the second part 322 and the third part 323 being a clip 311.

[0058] Please refer to Figures 2 to 6 In this embodiment, the first connector 10 is provided with a receiving groove 21, and the elastic member 30 is located in the receiving groove 21.

[0059] By adopting the above solution, the position of the elastic member 30 can be defined by the receiving groove 21, thereby facilitating the connection of the first connecting member 10 to the elastic member 30.

[0060] Optionally, the receiving groove 21 has opposing first inner walls and second inner walls, with the mating part 31 abutting against the first inner wall and the elastic abutting part 32 abutting against the second inner wall.

[0061] With this configuration, the first connector 10 and the elastic element 30 can be connected simply by placing the elastic element 30 in the receiving groove 21, so that the mating part 31 abuts against the first inner wall and the elastic abutting part 32 abuts against the second inner wall. The operation is simple and convenient.

[0062] Understandably, when installing the light fixture, the first connector 10 can be fixed to the ceiling first, and then the slot of the receiving groove 21 can be aligned with the retaining part 11 and pressed directly in. Due to the rebound force of the elastic member 30, it can be easily snapped in until the retaining part 11 is inserted between the mating part 31 and the elastic abutment part 32. The elastic abutment part 32 abuts against the retaining part 11, so that the mating part 31 and the retaining part 11 are engaged.

[0063] The lamp connection structure 100 provided in this application embodiment uses the elastic element 30 to spring back and install vertically, and to rotate and push to disassemble and install, so that the lamp body is protected from the risk of damage during installation and disassembly. It also avoids the danger of excessive force when installing and removing the lamp body on the ceiling, thus greatly improving safety.

[0064] Optionally, one of the mating part 31 and the first inner wall is provided with a first recess 312, and the other of the mating part 31 and the first inner wall is provided with a first protrusion 211, the first protrusion 211 being accommodated in the first recess 312; and / or, one of the elastically abutting part 32 and the second inner wall is provided with a second recess 324, and the other of the elastically abutting part 32 and the second inner wall is provided with a second protrusion 212, the second protrusion 212 being accommodated in the second recess 324.

[0065] This design prevents the first connector 10 from separating from the elastic member 30 when the first connector 10 and the second connector 20 are disassembled.

[0066] The elastic element 30 includes a connecting part 33, a mating part 31 and an elastic abutting part 32, which are respectively connected to the two ends opposite to the connecting part 33.

[0067] This design simplifies the structure of the elastic element 30 and makes it easier to manufacture.

[0068] It is understandable that the mating part 31 and the elastic support part 32 can be integrally molded.

[0069] Optionally, the bottom wall of the receiving groove 21 is fitted with the connecting part 33.

[0070] This configuration allows the position of the elastic element 30 to be better defined by the receiving groove 21.

[0071] The lamp connection structure 100 provided in the above embodiment is easy to manufacture and assemble. The elastic element 30 can be inserted into the receiving groove 21 with simple installation tools and is not easy to fall off. The precision requirements of the parts are low, the production is convenient, and the installation is easier. It is easy to know whether the installation is in place and reduce the risk of falling off. At the same time, it is easy to disassemble. It can be removed by slightly rotating it in the required direction.

[0072] Secondly, embodiments of this application provide a lighting fixture, which includes the lighting fixture connection structure 100 as described in the first aspect.

[0073] Please refer to Figures 1 to 6The lamp provided in this application embodiment has two holding portions 11 on the first connecting member 10, which are spaced apart. The two elastic members 30 are symmetrical about the central axis O of the second connecting member 20. Each elastic member 30 corresponds to one of the holding portions 11 and is connected to the second connecting member 20. Each elastic member 30 includes a mating portion 31 and an elastic abutment portion 32, which are spaced apart around the central axis O. Therefore, when installing the lamp, it is possible to first... The first connector 10 is fixed to the ceiling, and then the retaining part 11 is inserted between the mating part 31 and the elastic abutment part 32, such that the mating part 31 and the elastic abutment part 32 are located on both sides of the retaining part 11. At this time, the elastic abutment part 32 abuts against the retaining part 11, so that the mating part 31 and the retaining part 11 can be engaged, thereby making it easier to connect the first connector 10 and the second connector 20. The first connector 10 and the second connector 20 are connected tightly and are not easy to fall off.

[0074] Meanwhile, when disassembling the first connector 10 and the second connector 20, simply rotate the second connector 20 relative to the first connector 10 around the central axis O, so that the holding part 11 moves away from the mating part 31 and abuts against the elastic abutting part 32, so that the holding part 11 can be disengaged from the mating part 31. The operation is simple and labor-saving, and the lamp body or ceiling is not easily damaged.
