Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of lamp fixing, in particular to a fixed structure of a lighting lamp. BACKGROUND

[0002] In the field of lighting lamps, the stability and flexibility of the fixing structure of the lamp are also the key to realizing stable lighting of the lamp. The traditional fixing method often relies on screws or bolts to be directly fixed on the wall or ceiling. Although this method is firm, it is relatively cumbersome during installation and disassembly, and can easily damage the installation surface. Especially in modern commercial space and home decoration, with the popularity of the design of no master lamp, higher requirements are put forward for the flexibility, aesthetics and easy maintenance of the lighting lamp.

[0003] In the existing technology, the magnetic attraction fixing technology is gradually applied to the fixing of lighting lamps. The lamps are attracted to the track or special mounting plate by magnetic force, greatly simplifying the installation process and improving the flexibility of the lamps. However, the magnetic attraction fixing method also has certain limitations, such as the magnetic force may weaken over time, or there is a risk of falling when the weight of the lamp is large.

[0004] For example, the comparative document CN202020027484.X discloses a magnetic attraction track lamp, which comprises a lamp holder, two conductive strips and a guide rail box. The upper part of the cross section of the lamp holder is a guide rail groove with an open upper end. The two side walls of the guide rail groove are respectively provided with conductive strip mounting grooves. Two conductive strips are correspondingly clamped in the two conductive strip mounting grooves. The guide rail box has a box body that can be slidably connected with the guide rail groove. The two sides of the box body are provided with conductive springs that can be in sliding contact with the conductive strips on the two side walls of the guide rail groove. The bottom of the guide rail groove is fixedly provided with a magnetic attraction bottom plate, and the guide rail box is provided with a magnet that can be magnetically attracted to the magnetic attraction bottom plate. However, this scheme only uses a magnetic attraction structure to fix the lamp. Since the carrying capacity of the magnetic attraction structure is limited by the magnetic attraction force, there is a risk of falling when the weight of the lamp is large.

[0034] Further, the anti-unclamping connecting subassembly 120 comprises an anti-unclamping assembly 121 and a base shell 122, the inside of the base shell 122 is provided with a containing groove 1201, the anti-unclamping assembly 121 is arranged in the containing groove 1201, the anti-unclamping assembly 121 comprises a supporting piece 1211 and an elastic reset piece 1212, the supporting piece 1211 is connected to the elastic reset piece 1212, the supporting piece 1211 is arranged in the anti-unclamping passage 1101 and abuts against the elastic clamping part 114, and the elastic reset piece 1212 is spring-connected to the bottom of the containing groove 1201. The inside of the external metal groove is provided with an electrically connected rail and a clamping fixed groove matched with the spherical metal piece 112 and the elastic clamping part 114, the electrically connected rail is used for fixing the spherical metal piece 112, and the clamping fixed groove is used for clamping the protruding end of the elastic clamping part 114.

[0035] In the present embodiment, in the process of fixing the anti-off buckle combined magnetic attraction fixing structure 10 to the external metal groove body, one end of the spherical metal piece 112 is in contact with the inner wall of the external metal groove body and is extruded, and since the other end of the spherical metal piece 112 is spring-connected to the inner wall of the thin-edge shell 111, the spherical metal piece 112 is extruded into the thin-edge shell 111, then the elastic return piece 1212 is pressed, the elastic return piece 1212 drives the support piece 1211 to move vertically downward, at the same time, the support piece 1211 is separated from the elastic clamping part 114, the elastic clamping part 114 is in contact with the inner wall of the external metal groove body and is extruded, so that the elastic clamping part 114 is extruded into the buckle through slot 1102, so that the multi-structure fixing assembly 100 can abut against the internal metal groove body; when the spherical metal piece 112 is in the same horizontal plane as the power rail, under the action of elastic potential energy, the spherical metal piece 112 is arranged in the circular through hole 1103 and abuts against the power rail, at the same time, the elastic return piece 1212 is loosened, under the action of elastic potential energy, the elastic return piece 1212 drives the support piece 1211 to move vertically upward, the support piece 1211 abuts against the elastic clamping part 114 again, and under the supporting force of the support piece 1211, the protruding end of the elastic clamping part 114 is fixed in the clamping fixing groove, on the other hand, the magnetic attraction piece 113 is attracted to the inner wall of the external metal groove body under the action of magnetic field force, so that the anti-off buckle combined magnetic attraction fixing structure 10 is tightly fixed to the external metal groove body.

[0036] Further, in the process of separating the anti-off buckle combined magnetic attraction fixing structure 10 from the external metal groove body, the elastic return piece 1212 is pressed again, the elastic return piece 1212 drives the support piece 1211 to move vertically downward, so that the support piece 1211 is separated from the elastic clamping part 114, so that the elastic return piece 1212 loses the supporting force, at this time, a vertical downward force is applied to the multi-structure fixing assembly 100, so that the spherical metal piece 112 and the elastic clamping part 114 are in contact with the inner wall of the external metal groove body and are extruded, the spherical metal piece 112 is again extruded into the circular through hole 1103 under the action of external force, and the elastic clamping part 114 is again extruded into the buckle through slot 1102, so that the anti-off buckle combined magnetic attraction fixing structure 10 is separated from the external metal groove body.

[0037] The anti-falling buckle combined magnetic fixing structure 10 is fixed to the external metal groove body. The spherical metal part 112 abuts against the external metal groove body, so that the anti-falling buckle combined magnetic fixing structure 10 is fixed to the external metal groove body for the first time. Then, the elastic clamping part 114 is clamped to the external metal groove body, so that the anti-falling buckle combined magnetic fixing structure 10 is fixed to the external metal groove body for the second time. Finally, the magnetic attraction part 113 is attracted to the external metal groove body, so that the anti-falling buckle combined magnetic fixing structure 10 is fixed to the external metal groove body for the third time. Thus, the anti-falling buckle combined magnetic fixing structure 10 is fixed to the external metal groove body by the spherical metal part 112, the elastic clamping part 114 and the magnetic attraction part 113, the load-bearing strength of the anti-falling buckle combined magnetic fixing structure 10 is improved, and the problem that the lamp falls off due to insufficient load-bearing strength of the anti-falling buckle combined magnetic fixing structure 10 when the lamp is heavy is avoided.

[0038] As shown in Figure 2 , Figure 4 and Figure 5 , in one embodiment, the elastic clamping part 114 includes two clamping parts 1141, the buckle through groove 1102 penetrates through the two long edge end faces of the thin edge shell 111, one end of each clamping part 1141 is connected to the side of the buckle through groove 1102 away from the anti-falling buckle combined magnetic fixing structure 10, the other end of each clamping part 1141 is arranged in the buckle through groove 1102, and the anti-falling buckle through channel 1101 is arranged between the two clamping parts 1141. In this embodiment, during the process of fixing the anti-falling buckle combined magnetic fixing structure 10 to the external metal groove body, the two clamping parts 1141 are clamped to the clamping fixing grooves arranged on the inner wall of the external metal groove body under the action of the supporting part 1211, the connection strength between the thin edge fixing subassembly 110 and the clamping fixing grooves is improved, so that the risk of the anti-falling buckle combined magnetic fixing structure 10 being separated from the external metal groove body is reduced, and the stability of the anti-falling buckle combined magnetic fixing structure 10 is improved.

[0039] As shown in Figure 4As shown, in one embodiment, the spherical metal piece 112 includes a spherical protrusion 1121, an elastic fixing rod 1122, and a first spring piece 1123. The spherical protrusion 1121 is arranged in the circular through hole 1103. One end of the elastic fixing rod 1122 is connected to the spherical protrusion 1121, and the other end of the elastic fixing rod 1122 is connected to the bottom of the thin-edge shell 111. One end of the first spring piece 1123 abuts against the spherical protrusion 1121, and the other end of the first spring piece 1123 abuts against the side of the thin-edge shell 111 away from the circular through hole 1103. In this embodiment, during the process of fixing the anti-dropping buckle combined with the magnetic attraction fixing structure 10 to the external metal groove, the spherical protrusion 1121 is pressed by the external metal groove, and the spherical protrusion 1121 transmits the pressing force to the first spring piece 1123 and the elastic fixing piece, so that the first spring piece 1123 is compressed and stores elastic potential energy, thereby causing the spherical protrusion 1121 to be pressed into the thin-edge shell 111 through the circular through hole 1103. When the spherical metal piece 112 and the power connection rail of the external metal groove are at the same level, the spherical protrusion 1121 loses the pressing force, and at this time, the first spring piece 1123 releases the elastic potential energy, thereby causing the spherical protrusion 1121 to be pushed out of the thin-edge shell 111 through the circular through hole 1103 and abut against the power connection rail, thereby improving the stability of the anti-dropping buckle combined with the magnetic attraction fixing structure 10.

[0040] As shown, Figure 4 In one embodiment, a magnetic attraction through hole 1104 is arranged at the top of the thin-edge shell 111, one end of a magnetic attraction piece 113 is arranged in the magnetic attraction through hole 1104, and the other end of the magnetic attraction piece 113 is connected to the bottom of the thin-edge shell 111. In this embodiment, the magnetic attraction piece 113 is arranged in the thin-edge shell 111, and one end of the magnetic attraction piece 113 is connected to the bottom of the thin-edge shell 111. When the magnetic attraction piece 113 is attracted to the external metal groove, the other end of the magnetic attraction piece 113 is arranged in the magnetic attraction through hole 1104 at the top of the thin-edge shell 111, so that the magnetic attraction piece 113 can contact the external metal groove, and the magnetic attraction piece 113 connects the external metal groove and the thin-edge shell 111 as a whole through the magnetic field force, thereby improving the connection strength between the anti-dropping buckle combined with the magnetic attraction fixing structure 10 and the external metal groove.

[0041] As shown, Figure 3 and Figure 4As shown, in one embodiment, the elastic reset member 1212 further comprises a toggle link 12121 and a second spring member 12122. The anti-unhooking assembly 121 is provided with a clearance groove 1202 adjacent to the short edge end surface of the anti-unhooking channel 1101. The toggle link 12121 is arranged in the clearance groove 1202 and connected to the middle portion of the support member 1211. One end of the second spring member 12122 abuts against the support member 1211, and the other end of the second spring member 12122 abuts against the bottom of the base shell 122. The toggle link 12121 is used for manual toggling or pressing down, so that the toggle link 12121 can vertically slide in the clearance groove 1202. In this embodiment, during the process of fixing the anti-unhooking buckle combined with magnetic attraction fixing structure 10 to the external metal groove, since the toggle link 12121 is connected to the support member 1211 and the two ends of the second spring member 12122 are respectively connected to the support member 1211 and the base shell 122, when the toggle link 12121 is pressed and abuts against the bottom surface of the clearance groove 1202, the external applied force is transmitted to the second spring member 12122, so that the second spring member 12122 converts mechanical energy and stores it as elastic potential energy. When the toggle link 12121 is released, the second spring member 12122 loses the external force and releases the elastic potential energy. The elastic potential energy is converted into kinetic energy by the second spring member 12122 and transmitted to the support member 1211 to move vertically upward. The support member 1211 simultaneously drives the toggle link 12121 to move vertically upward and disengage from the bottom surface of the clearance groove 1202, so that the anti-unhooking buckle combined with magnetic attraction fixing structure 10 can be quickly installed or disassembled by applying force through the toggle link 12121, thereby improving the disassembly convenience of the anti-unhooking buckle combined with magnetic attraction fixing structure 10.

[0042] As shown, Figure 4 In one embodiment, the anti-unhooking assembly 121 further comprises a spring fixing member 1213. The spring fixing member 1213 is arranged at the end of the base shell 122. A spring accommodating cavity 1203 is formed in the spring fixing member 1213 and is communicated with the anti-unhooking channel 1101. The second spring member 12122 is arranged in the spring accommodating cavity 1203. In this embodiment, the second spring member 12122 converts kinetic energy into elastic potential energy and deforms under the action of external force. Since the second spring member 12122 is arranged in the spring accommodating cavity 1203, the deformation path of the second spring member 12122 is limited, so that the second spring member 12122 is compressed and rebounded in the vertical direction, thereby facilitating the conversion of elastic potential energy into kinetic energy and acting on the support member 1211, and further ensuring that the support member 1211 can accurately abut against the elastic clamping portion 114.

[0043] As shown, Figure 4As shown, in one embodiment, the thin-edge fixing subassembly 110 further comprises a threaded connecting piece 115 and a fastening screw 116. The threaded connecting piece 115 is fixed to the bottom of the thin-edge shell 111, and the top of the thin-edge shell 111 is provided with a first fixing through hole 1105. A threaded passage 1106 is formed in the threaded connecting piece 115. The fastening screw 116 is threadedly connected in the first fixing through hole 1105 and the threaded passage 1106. In this embodiment, since the fastening screw 116 passes through the threaded passage 1106 and is arranged in the first fixing through hole 1105 of the thin-edge shell 111, and the threaded connecting piece 115 is fixed to the bottom of the thin-edge shell 111, the bottom of the thin-edge shell 111 is connected to the top of the base shell 122, so that the thin-edge fixing subassembly 110 and the anti-dropping connecting subassembly 120 are tightly fixed and connected, avoiding the existence of gaps between the thin-edge fixing subassembly 110 and the anti-dropping connecting subassembly 120, which causes the anti-dropping buckle combined magnetic attraction fixing structure 10 to be offset during the fixing process, thereby improving the stability of the anti-dropping buckle combined magnetic attraction fixing structure 10.

[0044] As shown in the drawings, Figure 3 In one embodiment, the number of the spherical metal pieces 112, the magnetic attraction pieces 113 and the elastic clamping portions 114 is two. One end of each of the spherical metal pieces 112 is protrudingly arranged at the two opposite long edge end faces of the thin-edge shell 111. Each of the elastic clamping portions 114 is arranged in the buckle through slot 1102 formed at the two ends of the long edge of the thin-edge shell 111. Each of the magnetic attraction pieces 113 is arranged between each of the spherical metal pieces 112 and each of the elastic clamping portions 114. In this embodiment, since the number of the spherical metal pieces 112, the magnetic attraction pieces 113 and the elastic clamping portions 114 is two, and each of the spherical metal pieces 112, each of the magnetic attraction pieces 113 and each of the elastic clamping portions 114 is arranged in the thin-edge fixing subassembly 110, the anti-dropping buckle combined magnetic attraction fixing structure 10 can bear a larger lamp weight, thereby increasing the load-bearing strength of the anti-dropping buckle combined magnetic attraction fixing structure 10.

[0045] As shown in the drawings, Figure 3As shown, in one embodiment, the lamp assembly 200 includes a lamp body connector 210 and a lamp rotating member 220, the lamp body connector 210 is connected to the anti-unhooking connector subassembly 120, and the lamp rotating member 220 is rotatably connected to the lighting lamp. In this embodiment, the lamp body connector 210 of the lamp assembly 200 is connected to the bottom of the anti-unhooking connector subassembly 120. After the anti-unhooking buckle combination magnetic attraction fixing structure 10 is fixed to the external metal groove body, the lighting lamp connected to the lamp rotating member 220 of the lamp assembly 200 can be adjusted in rotation to adjust the lighting angle. In addition, since the anti-unhooking buckle combination magnetic attraction fixing structure 10 is stably connected to the external metal groove body through the ball-shaped metal piece 112, the magnetic attraction piece 113, and the elastic clamping portion 114 of the thin-edge fixing subassembly 110, the lamp assembly 200 can bear a lighting lamp with a relatively large connection weight, so that the anti-unhooking buckle combination magnetic attraction fixing structure 10 can be applied to more complex lighting environments.

[0046] As shown, Figure 5 In one embodiment, the short edge width d of the thin-edge shell 111 is in the range of 3.5mm to 4.5mm. In this embodiment, since the short edge width d of the thin-edge shell 111 is in the range of 3.5mm to 4.5mm, the thickness of the thin-edge shell 111 is thinner than that of the conventional fixing structure, and a lightweight design is achieved, thereby reducing the weight of the anti-unhooking buckle combination magnetic attraction fixing structure 10 and improving the disassembly efficiency of the anti-unhooking buckle combination magnetic attraction fixing structure 10.

[0047] The lighting lamp comprises a light source and the anti-detaching buckle combined magnetic fixing structure 10. In the process of fixing the anti-detaching buckle combined magnetic fixing structure 10 to the external metal groove, one end of the spherical metal piece 112 is in contact with the inner wall of the external metal groove and is extruded, because the other end of the spherical metal piece 112 is spring-connected to the inner wall of the thin-edge shell 111, the spherical metal piece 112 is extruded into the thin-edge shell 111, then the elastic reset piece 1212 is pressed, the elastic reset piece 1212 drives the support piece 1211 to move vertically downward, the support piece 1211 is separated from the elastic clamping part 114, the elastic clamping part 114 is in contact with the inner wall of the external metal groove and is extruded, so that the elastic clamping part 114 is extruded into the buckle through slot 1102, so that the multi-structure fixing assembly 100 can abut against the internal metal groove; when the spherical metal piece 112 is in the same horizontal plane as the power rail, under the action of elastic potential energy, the spherical metal piece 112 is arranged in the circular through hole 1103 and abuts against the power rail, at the same time, the elastic reset piece 1212 is loosened, under the action of elastic potential energy, the elastic reset piece 1212 drives the support piece 1211 to move vertically upward, the support piece 1211 abuts against the elastic clamping part 114 again, and the convex end of the elastic clamping part 114 is fixed to the clamping fixing groove under the supporting force of the support piece 1211, on the other hand, the magnetic attraction piece 113 is adsorbed to the inner wall of the external metal groove under the action of magnetic field force, so that the anti-detaching buckle combined magnetic fixing structure 10 is fixed to the external metal groove tightly. Further, in the process of separating the anti-detaching buckle combined magnetic fixing structure 10 from the external metal groove, the elastic reset piece 1212 is pressed again, the elastic reset piece 1212 drives the support piece 1211 to move vertically downward, so that the support piece 1211 is separated from the elastic clamping part 114, so that the elastic reset piece 1212 loses the supporting force, at this time, a vertical downward force is applied to the multi-structure fixing assembly 100, so that the spherical metal piece 112 and the elastic clamping part 114 are in contact with the inner wall of the external metal groove and are extruded, the spherical metal piece 112 is again extruded into the circular through hole 1103 under the action of external force, and the elastic clamping part 114 is again extruded into the buckle through slot 1102, so that the anti-detaching buckle combined magnetic fixing structure 10 is separated from the external metal groove.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1. The anti-off buckle combined magnetic attraction fixing structure 10, in the process of fixing the anti-off buckle combined magnetic attraction fixing structure 10 to the external metal groove, the spherical metal piece 112 is abutted to the external metal groove, so that the anti-off buckle combined magnetic attraction fixing structure 10 is fixed to the external metal groove for the first time, then the elastic clamping part 114 is clamped to the external metal groove, and the anti-off buckle combined magnetic attraction fixing structure 10 is fixed to the external metal groove for the second time, and finally the magnetic attraction piece 113 is adsorbed to the external metal groove, so that the anti-off buckle combined magnetic attraction fixing structure 10 is fixed to the external metal groove for the third time, and the anti-off buckle combined magnetic attraction fixing structure 10 is fixed to the external metal groove by the spherical metal piece 112, the elastic clamping part 114 and the magnetic attraction piece 113, thereby improving the load strength of the anti-off buckle combined magnetic attraction fixing structure 10, and avoiding the problem that the lamp falls off due to insufficient load strength of the anti-off buckle combined magnetic attraction fixing structure 10 when the lamp is heavy.
