Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and more particularly to a track light accessory, specifically a locking structure suitable for track lights. Background Technology

[0002] Track lights consist of lamps embedded in a matching guide rail. The power supply components of the lamps contact conductive strips on the rail, allowing the lamps to move, change position, and adjust the beam angle along the rail to achieve focused illumination of a target. Currently, track lights are primarily installed on the rail using magnetic or push-button methods. However, these two methods have the following drawbacks for recessed track lights:

[0003] 1. Magnetic installation: The magnetism of the magnet is affected by temperature changes, which cannot guarantee its reliability. The internal control circuit will also be affected by the magnet, which will affect the life of the lamp.

[0004] 2. Button installation: Adding extra buttons to the end of the control box is difficult for recessed track lights, as it is hard to reach into the guide rail to operate them.

[0005] Because recessed track lights have considerable depth, especially in applications like ceiling lights where the track opening faces downwards, installation is done from bottom to top, increasing the difficulty. In view of these drawbacks, to increase the reliability of light fixture installation and facilitate assembly and disassembly, those skilled in the art have dedicated themselves to developing a light fixture locking structure. Summary of the Invention

[0006] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that the existing track lights are inconvenient to install and remove and have poor reliability after installation.

[0007] To achieve the above objectives, the present invention provides a lamp locking structure, including a control box connected to a guide rail. The control box has elastic latching assemblies on both sides of its width relative to the guide rail. Each elastic latching assembly includes a latching member and a first reset member that elastically connects to the latching member. The control box also contains a clutch member that engages with the elastic latching assembly. The clutch member moves relative to the latching member and can drive the latching member to reciprocate along its width. The first reset member resets the latching member after the clutch member is released from its driving action. A drive rod passes through one end face of the control box. The drive rod has a central axis and moves along the direction of the central axis. One end of the drive rod can be connected to the clutch member for transmission.

[0008] Optionally, the first reset element is a compression spring, which provides an expansion force to the latching element to drive the latching element to extend out of the control box.

[0009] Furthermore, the elastic buckle assembly also includes a positioning pin, which is fixedly disposed in the control box along the width direction and passes through the buckle component along the width direction.

[0010] Alternatively, the elastic latching assembly includes two latching members respectively disposed on both sides of the control box along the width direction, a first reset member connected between the two latching members, and the latching members being subjected to a force exerted by the first reset member toward the outside of the control box.

[0011] Furthermore, the fastener includes an annular wall and a guide block formed on the annular wall, the guide block being adapted to engage with a guide rail; the clutch includes a connecting block and a driving block disposed on the outer periphery of the connecting block, the driving block moving with the clutch, the driving block being able to cut into the gap between the annular wall and the inner wall of the control box, thereby pushing the fastener toward the inside of the control box.

[0012] Furthermore, there are two drive blocks, located on both sides of the connecting block in the circumferential direction. The clutch rotates along the central axis L, causing the drive blocks to switch positions relative to the annular wall of the snap-fit ​​component.

[0013] Optionally, the connecting block of the clutch is circular, and the two sides of the control box in the width direction form positioning grooves that are adapted to the connecting block, and the positioning grooves on both sides limit the clutch.

[0014] Furthermore, the outer radial extension of the connecting block of the clutch forms a stop block, and the positioning groove interferes with the stop block to limit the circumferential rotation of the clutch.

[0015] Furthermore, the drive rod includes a connecting rod and a rotating shaft. The control box forms an axial sleeve on the end face through which the drive rod passes. The drive rod moves along the inner side of the sleeve. The rotating shaft is fixedly installed at the end of the connecting rod facing the clutch. The rotating shaft moves inside the control box and has a snap-fit ​​block at its end that engages with the clutch.

[0016] In one specific embodiment of the invention, the connecting block of the clutch has the shape of an internal gear.

[0017] Furthermore, the control box has a through hole on the end face of the sleeve side, through which the rotating shaft passes along the central axis L. The inner diameter of the through hole is smaller than the outer diameter of the connecting rod, and the end face of the control box limits the end of the connecting rod.

[0018] More preferably, the inner protrusion of the sleeve forms a first limiting block, and the outer protrusion of the connecting rod forms a second limiting block. When the second limiting block rotates circumferentially with the connecting rod, it is interfered with by the first limiting block.

[0019] More preferably, the rotating shaft extends radially inside the control box to form a first limiting surface, and the end face of the control box interferes with the first limiting surface.

[0020] In one specific embodiment of the present invention, the control box includes a top cover, and a second reset member is connected between the rotating shaft and the top cover.

[0021] The present invention also provides a method for unlocking a lamp locking structure, which uses the above-mentioned lamp locking structure and is characterized by the following steps: pushing the hand-held drive rod into the inside of the control box, so that the drive rod and the clutch are linked; rotating the drive rod, so that the clutch drives the buckle to retract into the control box, thereby releasing the connection between the control box and the guide rail.

[0022] The lamp locking structure of the present invention is used for connection with guide rail. The lamp can be connected to the inside of the guide rail while being embedded in the guide rail by the extension and retraction of the elastic buckle component. When unlocking is required, the elastic buckle component is driven to quickly unlock from the guide rail by operating the external drive rod, which improves the convenience of lamp loading and unloading from the guide rail. It is also equipped with a mechanism to prevent misoperation and a limiting structure, which improves the reliability of the lamp during use.

[0023] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Attached Figure Description

Detailed Implementation

[0038] like Figure 1 and Figure 3 The diagram shows a lamp locking structure for track lights according to the present invention, which includes a control box 1 connected to a guide rail 5. The control box 1 has elastic buckle components 2 on both sides of the guide rail 5 in the width direction. The control box 1 is connected to the inside of the guide rail 5. A power supply component 6 is provided on the side of the control box 1 to contact the guide rail 5 and supply power to the lamp.

[0039] like Figure 2The diagram shown is an exploded view of the lamp locking structure of the present invention. The elastic latch assembly 2 includes a latching member 21 and a first reset member 22 that elastically connects to the latching member 21. The first reset member 22 drives the latching member 21 to extend or retract to the side of the control box 1. The control box 1 also contains a clutch member 3 that cooperates with the elastic latch assembly 2. The clutch member 3 acts on the latching member 21, causing it to reciprocate. In a preferred embodiment, the clutch member 3 is movable relative to the latching member 21 and can apply force to the latching member 21 according to the position change of the clutch member 3, thereby driving the latching member 21 to move along the width direction. A drive rod 4 is inserted through one end face of the control box 1. The drive rod 4 has a central axis L and moves along the direction of the central axis L. One end of the drive rod 4 that penetrates into the control box 1 can be connected to the clutch member 3. According to the above structural design, the operator can manually change the state of the latching member 21 inside the drive box by manually operating the drive rod 4 outside the drive box.

[0040] Specifically, such as Figure 2 In the embodiment shown, the first reset member 22 is preferably a compression spring, which provides an expansion force to the latching member 21 to drive it out of the control box 1. Additionally, the elastic latching assembly 2 includes a positioning pin 23, which is fixedly disposed within the control box 1 along its width and passes through the latching member 21 along its width. The positioning pin 23 and the compression spring can be provided individually or in combination. In a preferred embodiment, the positioning pin 23 is disposed at both ends of the latching member 21, and two corresponding compression springs are provided and sleeved on the positioning pin 23. This improves the stability of the latching member 21 as it is driven by the compression springs on both sides.

[0041] For the case where the control box 1 is unidirectionally connected to the guide rail 5 along the width direction, one latching member 21 can be provided. The first reset member 22 drives the latching member 21 to extend and retract relative to the inner wall of the control box 1. However, most existing guide rails have a structure with conductive contact on both sides. Correspondingly, the elastic latching assembly 2 includes two latching members 21 respectively disposed on both sides of the control box 1 along the width direction. The first reset member 22 is connected between the two latching members 21. The positioning pin 23 passes through the latching members 21 on both sides and is fixedly installed inside the control box 1. The compression spring is sleeved on the positioning pin 23 and abuts against the latching members 21 at both ends. When the latching member 21 is subjected to an inward squeezing force in the width direction, the two latching members 21 move towards each other. When the squeezing force is released, the two latching members 21 are pushed away by the expansion force of the first reset member 22 until they extend out of the control box 1.

[0042] like Figure 4As shown, the clutch 3 is movably fitted at the end of the latching member 21. The clutch 3 includes a drive block 31, and the latching member 21 includes an annular wall 211 and a guide block 212 formed on the annular wall 211. The drive block 31 moves along the outer side of the annular wall 211. The clutch 3 also includes a connecting block 32 that moves against the end of the annular wall 211. The drive block 31 is formed around the periphery of the connecting block 32 and extends along the outer side of the annular wall 211. The clutch 3 includes an unlocking direction D1 in both the positive and negative directions of its movement relative to the latching member 21. When the drive block 31 moves along this unlocking direction D1, the drive block 31 interferes with the latching member 21, ultimately releasing the connection between the control box 1 and the guide rail 5. The annular wall 211 of the latching member 21 is disposed inside the control box 1. In the width direction of the control box 1, the annular wall 211 is adjacent to the inner wall of the control box 1 at intervals. The two sides of the control box 1 are provided with guide grooves 11 for the guide blocks 212 of the latching member 21 to extend and retract. When the driving block 31 moves along the unlocking direction D1, the driving block 31 cuts into the gap between the annular wall 211 and the inner wall of the control box 1, thereby moving the latching member 21 away from the inner wall of the control box 1 and pushing the latching member 21 towards the inside of the control box 1. The direction opposite to the unlocking direction D1 is the locking direction D2. When the driving block 31 moves along the locking direction D2, the driving block 31 leaves the gap and no longer acts on the latching member 21. The first reset member 22 makes the annular wall 211 of the latching member 21 approach the inner wall of the control box 1 again, and at the same time makes the guide block 212 extend along the guide groove 11 to cooperate and connect with the guide rail 5. Figure 5 As shown.

[0043] Preferably, in the case where two latching elements 21 are provided, two drive blocks 31 are also provided, and they are respectively provided on both sides of the clutch element 3 in the circumferential direction. Figure 2 as well as Figure 4 , Figure 5As shown, the annular walls 211 on both sides form a circular outline, and there is a gap between the annular walls 211 and the inner wall of the control box 1. The connecting block 32 of the clutch 3 is also set as a circular outline. The clutch 3 rotates along the central axis L and moves in a circumferential manner relative to the latching member 21. The driving block 31 moves against the outside of the annular wall 211 and switches positions relative to the annular wall 211. One end of the driving block 31 is formed as a pointed tip, which is suitable for cutting between the annular wall 211 and the inner wall of the control box 1. This end is defined here as the cutting end 311. Optionally, the cross-sectional shape of the drive block 31 is triangular or arc-shaped, with a narrow end and a wide middle; or it is triangular or horn-shaped, with a continuously changing shape that is narrow at one end and wide at the other. The above design of the drive block 31 makes it possible that when the drive block 31 moves along the unlocking direction D1, the cutting end 311 of the drive block 31 first cuts into the gap between the annular wall 211 and the inner wall of the control box 1. As the rotation of the cutting end 311 gradually enters along the gap, the drive block 31 contacts the annular wall 211 and generates a force. The distance between the annular wall 211 and the inner wall of the control box 1 is gradually squeezed apart as the width of the drive block 31 increases. The annular wall 211 gradually leaves the inner wall of the control box 1, so that the latch 21 moves towards the inside of the control box 1 and finally retracts into the control box 1 and disengages from the guide rail 5.

[0044] When the locking structure of this invention is applied to the installation of a lighting fixture, simply pushing the control box 1 into the guide rail 5 is sufficient to lock the guide rail 5. The guide block 212 includes a guide surface 212a inclined away from the drive rod 4 and a transverse surface 212b facing the drive rod 4. During installation, the control box 1 first enters the inner side of the guide rail 5. In the initial state, the first reset member 22 opens the latching member 21 outward, and the latching member 21 touches the mounting surfaces 51 of the two guide rails 5. The guide surface 212a is subjected to the reaction force of the mounting surfaces 51 of the guide rail 5, causing the guide block 212 to retract into the control box 1. After completely passing the mounting surfaces 51, the latching member 21 is no longer subjected to the force of the guide rail 5. The first reset member 22 acts on the latching member 21 and causes the latching member 21 to extend out of the control box 1. The transverse surface 212b rests on the upper end of the mounting surfaces 51 of the guide rail 5, thus securing the control box 1 in the guide rail 5 and completing the locking installation. Figure 7 As shown.

[0045] The control box 1 can be quickly and easily unlocked by operating the external drive lever 4. The movement of the clutch 3 is controlled by the drive lever 4, which includes a connecting rod 41 and a rotating shaft 42, as shown below. Figure 8As shown, the connecting rod 41 and the rotating shaft 42 can be separately connected, for example, the rotating shaft 42 can be snapped or screwed together at the ends. Alternatively, the connecting rod 41 and the rotating shaft 42 can be two integrally formed parts of the drive rod 4. The control box 1 forms an axial sleeve 12 on the end face where the drive rod 4 passes through, and the drive rod 4 moves adaptively along the inner side of the sleeve 12. The rotating shaft 42 is fixedly disposed at the end of the connecting rod 41 facing the clutch 3. The rotating shaft 42 is movable inside the control box 1, and its end is provided with a snap-fit ​​block 421 that engages with the clutch 3. Figure 6 As shown, the connecting block 32 of the clutch 3 forms an internal gear structure, and the locking block 421 at the end of the rotating shaft 42 can be engaged in the gear gap, thereby connecting with the clutch 3 and driving the rotation of the clutch 3 by the rotation of the rotating shaft 42. Preferably, at least two locking blocks 421 are provided and are evenly arranged circumferentially along the end of the rotating shaft 42.

[0046] Corresponding to one side of the sleeve 12, a through hole 13 is formed on the end face of the control box 1, communicating with the sleeve 12. The rotating shaft 42 for driving the rod 4 can pass through along the central axis L and enter the control box 1. The inner diameter of the through hole 13 is smaller than the outer diameter of the end of the connecting rod 41. After the rotating shaft 42 passes through the through hole 13, the end face of the control box 1 limits the end of the connecting rod 41, limiting the connecting rod 41 at the end face where the sleeve 12 and the control box 1 are connected. Furthermore, an annular groove 412 is formed on the connecting rod 41 for installing a sealing ring. The sealing ring is embedded between the sleeve 12 and the connecting rod 41 to achieve a waterproof and dustproof effect.

[0047] In the lamp of this invention, the drive rod 4, sleeve 12, and clutch 3 are all structures with a hole penetrating through the middle. One end of the drive rod 4 passes through the control box 1, and the other end is connected to the lamp. A wire connects the lamp and passes through the drive rod 4, sleeve 12, and clutch 3 before connecting to the circuit board inside the control box 1. The control box 1 is then connected to the guide rail 5 for power. Preferably, as follows... Figure 9 As shown, the inner protrusion of the sleeve 12 forms a first limiting block 15, and the outer protrusion of the connecting rod 41 forms a second limiting block 411. The first limiting block 15 is located within the rotation trajectory of the second limiting block 411. When the second limiting block 411 rotates circumferentially with the connecting rod 41, it is interfered with by the first limiting block 15. Since there is a wire inside, the rotation of the connecting rod 41 is restricted by the first limiting block 15 to prevent the wire inside the drive rod 4 from rotating excessively and causing entanglement, which would affect the connection performance.

[0048] The connecting block 32 of the clutch is annular, and positioning grooves 16 adapted to the connecting block 32 are formed on both sides of the control box 1 in the width direction. Figure 10The positioning grooves 16 on both sides limit the clutch 3; furthermore, the center of the arc where the two positioning grooves 16 are located or the center of symmetry is on the central axis L, so the clutch 3 is restricted between them, and the rotation axis 42 line also coincides with the central axis L, realizing the centering after installation.

[0049] Preferably, a stop block 321 is formed by radially extending the outer side of the connecting block 32 of the clutch 3. The positioning groove 16, protruding inward from the control box 1, has its outer edge capable of interfering with the stop block 321 to restrict the circumferential rotation of the clutch 3. The stop block 321 is positioned adjacent to the other end of the drive block 31 relative to the cutting end 311. Thus, after the drive block 31 rotates and drives the latch 21 to retract, the stop block 321 is constrained by the positioning groove 16, preventing the clutch 3 from rotating further. Figure 11 As shown.

[0050] The rotating shaft 42 extends radially inside the control box 1 to form a first limiting surface 422. The first limiting surface 422 is preferably an annular surface. The end face of the control box 1 interferes with the first limiting surface 422 to restrict the movement of the rotating shaft 42 along the central axis L. Further, the control box 1 includes a top cover 17. A second reset member 18, optionally a spring, is connected between the rotating shaft 42 and the top cover 17. The second reset member 18 is embedded in the inner cavity of the rotating shaft 42, and the reset force of the second reset member 18 pushes the rotating shaft 42 towards the connecting rod 41. Thus, for the drive rod 4, both the rotating shaft 42 and the connecting rod 41 are provided with limiting structures. When installed separately, the top cover 17 is opened, and the rotating shaft 42 passes through the control box 1 and connects with the connecting rod 41 to form the drive rod 4. Its movement towards and away from the control box 1 is limited by the end face of the control box 1, controlling the stroke of the drive rod 4.

[0051] Accordingly, the unlocking structure of the lamp in this application, wherein the movement of the drive rod 4 along the central axis L includes a coupled state and a free state:

[0052] Push the drive lever 4 into the control box 1 so that the end of the drive lever 4 engages with the clutch 3, thus entering the linkage state. The drive lever 4 can drive the clutch 3 to rotate. After the drive lever 4 rotates along the unlocking direction D1, the latch 21 retracts into the control box 1, releasing the connection with the guide rail 5. Conversely, after the drive lever 4 rotates along the locking direction D2, which is opposite to the unlocking direction D1, the latch 21 extends out of the control box 1, restoring the connection with the guide rail 5.

[0053] Pull the drive rod 4 out towards the lamp to enter the free state. In the free state, the drive rod 4 is separated from the clutch 3 and is limited by the end of the control box 1. The drive rod 4 can rotate circumferentially. Due to the limitation of the first limiting block 15 in the sleeve 12, the rotation range is less than 360°. At this time, the rotation of the drive rod 4 is not transmitted to the clutch 3, so there will be no misoperation of the buckle 21.

[0054] Based on the above structure, this application also provides a method for unlocking the lamp locking structure: in such a way Figure 12 (a) In the initial state, the hand-held drive lever 4 is pushed inwards towards the control box 1, causing the drive lever 4 and the clutch 3 to move together, such as Figure 12 (b) Then rotate the drive rod 4 to cause the clutch 3 to retract the locking mechanism into the control box 1, thus releasing the connection between the control box 1 and the guide rail 5. Figure 12 As shown in (c).

[0055] Accordingly, the locking structure of the present invention utilizes an elastic buckle assembly, allowing the lamp and the guide rail to be quickly connected. When unlocking is required, the drive rod can be operated to quickly unlock the lamp, improving the convenience of loading and unloading the lamp from the guide rail.

[0056] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
