Description

Technical Field

[0001] This utility model relates to the field of track lights, and in particular to a track connection structure. Background Technology

[0002] With the continuous development of lighting technology and the diversification of application scenarios, track lights, as a flexible and convenient lighting solution, have been widely used in commercial displays, home decoration, and public places. The core advantage of track lights lies in their ability to move and adjust freely on the track, meeting diverse lighting needs. However, in order to achieve greater lighting coverage in complex lighting layouts, the splicing and connection of the tracks becomes a crucial step.

[0003] In existing technologies, the track connection structure of track lights generally suffers from the following problems:

[0004] 1. Complex installation: Traditional track connection structures usually require multiple parts to be assembled, making the installation process cumbersome and inefficient.

[0005] 2. Insufficient reliability: Existing connection methods may become loose, misaligned, or even fall off after prolonged use or when subjected to external forces, affecting the stability of the track lights.

[0006] To address the aforementioned issues, there is an urgent need for a track connection structure that can simplify the track splicing process, improve connection stability, and balance flexibility and ease of installation, in order to meet the increasingly complex lighting design requirements. Utility Model Content

[0008] This utility model proposes a track connection structure for connecting at least two tracks, including connectors for connecting and fixing each track, a connecting body for connecting the connectors on each track, and a fixing member. The connector includes a hook structure facing the connecting body, and the top of the connecting body has a buckle hole adapted to the hook structure, with the hook structure hooking into the buckle hole. The fixing member is connected and fixed to the connecting body, and the fixing member has a limiting fixing part that blocks the hook structure from above, thereby limiting the hook structure in the buckle hole.

[0009] Preferably, the connecting body has a convex structure for inserting into the port of each track in a one-to-one correspondence, the convex structure being inserted into the port of the track.

[0010] Preferably, it further includes an electrical connector, which includes an electrical connector body and an electrical connector sub-body for installation on each track and electrically connected to the track. The electrical connector sub-body is connected to the electrical connector body via a connecting bridge, and the connecting line connecting the electrical connector sub-body and the electrical connector body passes through the connecting bridge.

The latch head and the limiting member are connected to the latch control button and move together with the latch control button. The latch head and the push-button latch match to form a push-button elastic self-locking mechanism. Pressing the latch control button causes the limiting member to move to the latch locking position—that is, the back of the cantilever hook—to abut against the cantilever hook; or to move to the latch unlocking position—that is, to disengage from the back of the cantilever hook, providing space for the cantilever hook to spring inward. The latch control button and the limiting member are positioned in the latch locking position and the latch unlocking position through the cooperation of the latch head and the push-button latch.

[0013] Preferably, there are at least two locking heads and two push-button locking heads, and all locking heads are connected to the buckle control button.

The baffle wall is inserted into the buckle hole.

[0017] Preferably, it further includes a connecting post with an internally threaded hole, the connecting post being pressed onto the fixing member, the connecting body having a first connecting hole, the fixing member having a second connecting hole, and the top cover having a third connecting hole. The first connecting hole, the second connecting hole, the third connecting hole, and the internally threaded hole correspond to each other, and are locked and fixed by screws passing through the first connecting hole, the third connecting hole, and the second connecting hole into the internally threaded hole, so that the connecting post, the fixing member, and the connecting body are connected and fixed.

[0018] Preferably, the limiting and fixing part is an outwardly protruding plate-shaped structure, and the connecting body is provided with limiting blocks located on both sides of at least one of the limiting and fixing parts.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] Reference Figures 1 to 13 This utility model embodiment provides a track connection structure for use in track lighting, used to connect at least two tracks. The track connection structure includes connectors 2 for connecting and fixing to each track 10, a connecting body 1 for connecting the connectors 2 on each track 10, and a fixing member 3. The connectors 2 are plate-shaped structures with multiple screw holes, and are fixed to the back end of the track 10 by screws.

[0039] The connector 2 includes an inverted L-shaped hook structure 21 facing the connecting body 1. The top of the connecting body 1 has a snap hole 11 adapted to the hook structure 21, and the hook structure 21 is hooked into the snap hole 11. The fastener 3 is connected and fixed to the top of the connecting body 1. The fastener 3 has a limiting and fixing part 31 that blocks the hook structure 21 from above, thereby blocking and limiting the hook structure 21 in the snap hole 11.

[0040] During assembly, first connect and fix the connector 2 to the track 10, then hook the hook structure 21 into the buckle hole 11, and then fix the fastener 3 to the connecting body 1. The hook structure 21 is blocked and limited in the buckle hole 11 by the limiting and fixing part 31 on the fastener 3, so that multiple tracks 10 can be connected. The connection and assembly of the connector 2 and the connecting body 1 is convenient.

[0041] To ensure a more stable track connection, a convex structure is provided on the connecting body 1 for one-to-one insertion with the ports of each track 10. The convex structure is inserted into the ports of the track 10, making the connection more stable and secure. In this embodiment, the convex structure is composed of convex walls 12 located on both sides.

[0042] As shown in the figure, the fixing component 3 includes a disc body, and the limiting fixing component 31 is a plate-shaped structure protruding outward from the edge of the disc body. The fixing component 3 is pressed and fixed by the connecting post 4. A top cover plate 5 is provided on the top of the connecting body 1, and the fixing component 3 is located on the top cover plate 5. The connecting post 4 is pressed on the fixing component 3. The connecting post 4 has a threaded hole 41 through it. The connecting body 1 has a first connecting hole 16, the fixing component 3 has a second connecting hole 32, and the top cover plate 5 has a third connecting hole 53. The first connecting hole 16, the second connecting hole 32, the third connecting hole 53 and the threaded hole 41 correspond to each other. Screws 6 are installed from the top inner surface of the connecting body 1. The screws 6 pass through the first connecting hole 16, the third connecting hole 53 and the second connecting hole 32 and are locked in the threaded hole 41 to fix them, so that the connecting post 4, the fixing component 3 and the connecting body 1 are connected and fixed.

[0043] The top cover plate 5 has a through hole 51 corresponding to the buckle hole 11. A retaining wall 52, corresponding to the vertical surface of the hook structure 21, is vertically provided inside the through hole 51. The retaining wall 52 is inserted into the buckle hole 11 and abuts against the inner side of the buckle hole 11. The retaining wall 52 can withstand the force applied by the vertical surface of the hook structure 21, preventing wear on the connecting body 1.

[0044] The top of the connecting body 1 is provided with limiting blocks located on both outer sides of one of the limiting and fixing parts 31, with the limiting blocks extending from the through holes 51 of the top cover plate 5. One limiting block is set slightly higher than the bottom surface of the limiting and fixing part 31, and its top surface is an arc surface, called the low limiting block 15; the other limiting block is higher, and in this embodiment, the other limiting block is almost flush with the top surface of the limiting and fixing part 31, called the high limiting block 14. The setting of the low limiting block 15 allows the fixing member 3 to slide from the top of the low limiting block 15 to between the two limiting blocks by rotation when it is not fully pressed by the connecting column 4, and then tighten the screws so that the connecting column 4 presses the fixing member 3, and the limiting and fixing part 31 is limited between the two limiting blocks.

[0045] In this embodiment, the connecting body 1 is a square shape, and the track 10 is connected to any side of the connecting body 1 via connector 2. A maximum of four tracks can be connected, with each track connected to one of the four sides of the connecting body 1 via connector 2. Figure 1 The diagram shown illustrates the connection between two tracks. Figure 2 The diagram shows the connection between a track group formed by three connected tracks and a track group formed by four connected tracks.

[0046] The internal threaded hole 41 of the connecting column 4 can be used to connect the hanger rod, thereby suspending and installing the connected track assembly.

[0047] To achieve electrical connection between the connected rails 10, an electrical connector is provided. The electrical connector includes an electrical connector body 7 and an electrical connector sub-body 9 for installation on each rail 10 and for electrical connection with the rail 10. The electrical connector sub-body 9 is connected to the electrical connector body 7 through a connecting bridge 8, and the connecting wire for electrical connection between the electrical connector sub-body 9 and the electrical connector body 7 passes through the connecting bridge 8.

[0048] The convex structure has a through groove 13, which is spaced between two convex walls 12. The electrical connector body 7 is installed in the inner cavity of the connecting body 1, and the connecting bridge 8 passes through the through groove 13. The electrical connector sub-body 9 has a conductive piece that contacts and connects with the conductive strip on the track 10. The electrical connector sub-body 9 is electrically connected to the track 10 through the conductive piece. Each electrical connector sub-body 9 is electrically connected to the positive and negative conductive pieces in the electrical connector body 7 through connecting wires, thereby realizing the electrical connection between each track 10.

[0049] The electrical connection unit 9 includes cantilever hooks 921 located on both sides for connection with the track latch, a fixedly installed push-button latch, a latch head 931, a limiting member 932 located on the back of each cantilever hook 921, and a movably installed latch control button 93. The limiting member 932 is a strip-shaped limiting plate. The latch head 931 and the limiting plate are integrally formed on the latch control button 93, and the latch head 931 and the limiting plate move together with the latch control button 93. The latch head 931 and the push-button latch match to form a push-type elastic self-locking mechanism. The push-type elastic self-locking mechanism is existing technology, and its specific structure will not be described in detail.

[0050] Each electrical connector 9 has two locking heads 931 and two push-button locking heads, all integrally formed on the latch control button 93. The electrical connector 9 includes an upper shell 91 and a lower shell 92 connected to the lower part of the upper shell 91. The upper shell 91 and lower shell 92 are connected to form a housing with a mounting cavity. The outer end of the housing has an opening communicating with the mounting cavity. The push-button locking head is fixed inside the mounting cavity, and the latch control button 93 is movably mounted in the mounting cavity, with its pressing end protruding from the outer end opening of the housing. The two sides 933 of the pressing end of the latch control button 93 are rounded to facilitate sliding. The top of the upper shell 91 has a latch through hole 911 and a limiting hole 912 including a latch locking position and a latch unlocking position. A cantilever hook 921 is provided on the lower shell 92, with the hook portion of the cantilever hook 921 extending from the latch through hole 911 to the top of the upper shell 91. The limiting member 932 extends from the limiting hole 912 to the top of the upper shell 91, and the position of the limiting member 932 is limited within the limiting hole 912.

[0051] The extended cantilever hook 921 connects with the corresponding slot on the track 10 via its hook portion, thus securing the electrical connector 9 to the track 10. Pressing the latch control button 93 once advances the latch head 931, moving the limiting member 932 to the latch's locked position—the rear of the cantilever hook 921—to abut against it. The latch control button 93 is positioned by the cooperation of the latch head 931 and the latch, thereby positioning the limiting member 932 in the latch's locked position. The limiting member 932 abuts against the cantilever hook 921, preventing it from being pressed inward and maintaining it in the latched position with the track, ensuring a secure connection. Press the buckle control button 93 again, and the push-type buckle will pop out the buckle head, causing the buckle control button 93 to pop out and reset. The limit member 932 moves to the buckle unlock position - that is, it is disengaged from the back of the cantilever hook 921, providing space for the cantilever hook 921 to spring inward so that the electrical connector 9 can be removed from the track.

[0052] A guide block 934 is also provided on the outer side of the arc surface, and a guide groove is provided on the side of the housing. The guide block 934 is located in the guide groove, which limits the movement path of the snap-on control button 93. When the snap-on control button 93 is pressed inward or popped outward, the guide block 934 moves in the guide groove.
