Description

Technical Field

[0001] This utility model specifically relates to a track spotlight structure. Background Technology

[0002] Track spotlights, as adjustable lighting devices commonly used in commercial displays and home spaces, typically consist of two parts: a track connector and a lamp body. They must simultaneously meet the requirements of quick disassembly and maintenance of the lamp body, flexible adjustment of the horizontal illumination angle, and stable positioning.

[0003] In existing technologies, the connection between the lamp body and the track connector mostly uses bolt locking or ordinary snap-fit ​​structures: bolt connections require tools for disassembly and assembly, resulting in low efficiency and inconvenience for later maintenance and replacement; while ordinary snap-fit ​​structures are quick to assemble and disassemble, their connection strength is insufficient, and they are prone to loosening after external force or long-term vibration, posing a safety hazard. Furthermore, in terms of angle adjustment, existing solutions use friction damping positioning, relying on the friction between components to maintain the angle. After long-term use, wear on the damping surface leads to a decrease in damping force, causing the lamp body to easily shift at the angle, resulting in poor positioning reliability. Utility Model Content

[0004] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a track spotlight structure.

[0005] A track spotlight structure includes a track connecting part and a lamp body. The lamp body is detachably connected to the track connecting part. The track connecting part has an extension on its lower side and a hanging rod inside the extension. The upper end of the lamp body has a hook that can cooperate with the hanging rod, so that the lamp body can be suspended on the hanging rod through the hook.

[0006] The hook is provided with several flanges spaced around the circumference of the hanging rod on the outer side, and a groove is formed between adjacent flanges. The extension is provided with a limiting member that can elastically extend and retract in the direction of the groove. The limiting member elastically abuts against the groove to limit and lock the rotation angle between the hook and the hanging rod.

[0007] In one embodiment, the lamp body includes a lamp housing, an LED lamp, a lens, and an adjusting ring. The lamp housing has a lower-opening lamp cavity, the LED lamp is disposed within the lamp cavity, the adjusting ring is rotatably disposed within the lamp cavity, and the adjusting ring has several guide grooves extending through its circumference. The lens is disposed within the inner ring of the adjusting ring, and several fixed shafts are provided on the outer periphery of the lens. The fixed shafts are movably disposed in the guide grooves in a corresponding manner. At least one limiting groove is provided vertically on the inner sidewall of the lamp cavity, and at least one limiting protrusion is provided on the outer edge of the lens. The limiting protrusion is slidably adapted to the limiting groove.

[0008] In one embodiment, the lamp housing includes an upper housing and a lower housing that are detachably connected to each other. A first limiting cavity is formed between the upper housing and the lower housing. The adjusting ring is co-centered in the first limiting cavity, and the adjusting ring is restricted by the first limiting cavity to only rotate circumferentially relative to the lamp housing and cannot move axially.

[0009] In one embodiment, the number of guide grooves is three, and they are evenly distributed along the circumference of the adjusting ring. The number of fixed shafts is the same as the number of guide grooves and they correspond one-to-one.

[0010] In one embodiment, the adjusting ring is rotatably disposed within the lamp cavity along the same central axis, and a silicone ring is pressed between the lamp cavity and the adjusting ring, thereby generating damping when the adjusting ring rotates relative to the lamp cavity through the silicone ring.

[0011] In one embodiment, the lower end of the extension is recessed into a groove, the hanging rod is horizontally placed in the groove, a second limiting cavity is formed between the upper side of the hanging rod and the bottom side of the groove, and the limiting member can elastically extend into the second limiting cavity and abut against the slot.

[0012] In one embodiment, the limiting member includes a spring and a limiting rod. The extension has a cavity, and a guide hole communicating with a second limiting cavity is provided through one side of the cavity. The limiting rod is movably inserted into the guide hole. A limiting part is provided on the limiting rod within the cavity. The spring is sleeved on the limiting rod and abuts against the limiting part and the cavity. A vertical groove communicating with the cavity is provided through one side of the extension. The limiting part partially extends through the vertical groove to the outside of the extension.

[0013] In one embodiment, the limiting rod at the end of the slot is tapered.

[0014] In summary, the advantages of this utility model over the prior art are:

[0015] This invention achieves linear up-and-down focusing of the lens by incorporating a rotatable adjusting ring within the lamp cavity and a guide groove on the ring, in conjunction with a fixed shaft on the lens and a limiting slide groove on the inner wall of the lamp cavity. The lens does not rotate during adjustment, effectively preventing light spot shift and ensuring stable lighting effects. Furthermore, no parts of the lamp body need to be disassembled; simply rotating the adjusting ring quickly adjusts the focus, making operation simple and convenient, achieving tool-free rapid focusing.

[0016] Furthermore, the hanging rod and hook work together to achieve a suspended and detachable connection between the lamp body and the track connection. The installation and disassembly process is simple and quick, requiring no tools, which facilitates users' later maintenance and replacement of the lamp body.

[0017] Furthermore, by setting multiple slots on the outer side of the hook and using elastic telescopic limiting components, the lamp body's horizontal rotation angle can be adjusted in multiple positions and automatically locked. Users only need to rotate the lamp body to switch between different illumination angles. After releasing, the limiting components automatically engage with the corresponding slots to lock the lamp. The adjustment is highly precise, and there will be no loosening even after long-term use, ensuring the stability of the illumination angle. Attached Figure Description

[0018] Figure 1 This is an exploded view of a track spotlight structure according to one embodiment of the present invention;

[0019] Figure 2 This is a cross-sectional view of a track spotlight structure in one embodiment of the present invention;

[0020] Figure 3 This is a perspective view of a track spotlight structure in one embodiment of the present invention. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 3 The present invention preferably provides a track spotlight structure, including a track connecting part 1 and a lamp body 2. The lamp body 2 is detachably connected to the track connecting part 1. The track connecting part 1 has an extension part 11 on its lower side, and a hanging rod 12 is provided in the extension part 11. The lamp body 2 has a hook part 13 at its upper end that can cooperate with the hanging rod 12, so that the lamp body 2 can be suspended on the hanging rod 12 by means of the hook part 13.

[0023] Specifically, when installing the lamp body, align the hook at the top of the lamp body with the hanging rod inside the extension section, and push the lamp body upward to hook the hook onto the hanging rod, thus completing the suspension connection between the lamp body and the track connection section; when disassembling the lamp body, simply pull the lamp body downward to disengage the hook from the hanging rod, and the lamp body can be removed from the track connection section.

[0024] It is worth noting that the hook is fixedly installed on the lamp body, and there is a clearance between the hook and the lamp body so that the hanging rod can pass through the clearance to engage with the hook, or pass through the clearance to disassemble and detach from the hook.

[0025] Furthermore, the hook portion 13 has several flanges 14 spaced circumferentially around the hanging rod 12 on its outer side, and a groove is formed between adjacent flanges 14. The extension portion 11 has a limiting member 15 that can elastically extend and retract towards the groove. The limiting member 15 elastically abuts against the groove to limit and lock the rotation angle between the hook portion 13 and the hanging rod 12. Furthermore, the lower end of the extension portion 11 has a recessed groove 16. The hanging rod 12 is placed horizontally in the groove 16. A second limiting cavity is formed between the upper side of the hanging rod 12 and the bottom side of the groove 16. The limiting member 15 can elastically extend into the second limiting cavity and abut against the groove. Furthermore, the limiting member 15 includes a spring 17 and a limiting rod 18. The extension 11 has a cavity 19. A guide hole 20 communicating with the second limiting cavity is provided through one side of the cavity 19. The limiting rod 18 is movably inserted into the guide hole 20. A limiting part 21 is provided on the limiting rod 18 within the cavity 19. The spring 17 is sleeved on the limiting rod 18 and abuts against the limiting part 21 and the cavity 19. A vertical groove 22 communicating with the cavity 19 is provided through one side of the extension 11. The limiting part 21 partially extends through the vertical groove 22 to the outside of the extension 11.

[0026] In its natural state, the spring force pushes the limiting part towards the second limiting cavity, thereby causing the limiting rod to extend out of the guide hole and engage in the slot of the hook, thus locking the rotation angle of the lamp body. When 360° unrestricted rotation or disassembly is required, the user pulls the limiting part extending to the outside of the extension along the vertical groove. The limiting part drives the limiting rod towards the cavity and compresses the spring, causing the limiting rod to disengage from the slot. At this point, the lamp body can be freely rotated or disassembled / installed. After releasing the limiting part, the spring force will again push the limiting rod out and engage in the corresponding slot.

[0027] It is worth noting that the height of the second limiting cavity is greater than the distance between the hook end and its center, so that after the hook part is disengaged from the hanging rod, it can directly disengage from the hanging rod and move out.

[0028] The lamp body 2 includes a lamp housing 3, an LED lamp 4, a lens 5, and an adjusting ring 6. The lamp housing 3 has a lamp cavity with a lower opening. The LED lamp 4 is disposed in the lamp cavity. The adjusting ring 6 is rotatably disposed in the lamp cavity. The adjusting ring 6 has several guide grooves 7 extending through its circumference. The lens 5 is disposed in the inner ring of the adjusting ring 6. Several fixed shafts 8 are provided on the outer periphery of the lens 5. The fixed shafts 8 are movably disposed in the guide grooves 7. The inner sidewall of the lamp cavity has at least one limiting groove 99 extending vertically. At least one limiting protrusion (not shown in the figure) is provided on the outer edge of the lens 5. The limiting protrusion (not shown in the figure) slides and adapts to the limiting groove 99.

[0029] Specifically, when adjusting the focus of the track spotlight, the user rotates the adjusting ring located inside the lamp cavity, causing the guide groove on the adjusting ring to rotate accordingly. Since the fixed shaft on the lens is movably positioned within the guide groove, and the limiting protrusion on the outer edge of the lens is restricted to vertical movement by the limiting slide groove on the inner wall of the lamp cavity, the rotation of the guide groove drives the lens to move vertically up and down along the limiting slide groove via the fixed shaft. When the lens moves upward, the distance between it and the LED light decreases, and the light spot becomes larger; when the lens moves downward, the distance between it and the LED light increases, and the light spot becomes smaller, thus achieving focus adjustment.

[0030] Furthermore, the lamp housing 3 includes an upper housing 9 and a lower housing 10 that are detachably connected to each other. A first limiting cavity is formed between the upper housing 9 and the lower housing 10. The adjusting ring 6 is co-centered in the first limiting cavity, and the adjusting ring 6 is restricted by the first limiting cavity to only rotate circumferentially relative to the lamp housing 3 and cannot move axially.

[0031] Specifically, the lamp housing adopts a split structure, consisting of a detachable upper housing and a lower housing. During assembly, the adjusting ring is first placed in the corresponding position on the upper or lower housing, and then the upper and lower housings are fastened together. The first limiting cavity formed between them simultaneously abuts against the upper and lower end faces of the adjusting ring, thus completely confining the adjusting ring within the first limiting cavity, allowing it to rotate only around the central axis without any axial displacement. This structure not only ensures the stability of the adjusting ring's rotation but also makes assembly and disassembly very convenient.

[0032] It is worth noting that after the upper and lower shells are fastened together, they are locked together. During the rotation of the adjusting ring, the lower shell will not rotate in a circular motion with the adjusting ring.

[0033] Furthermore, the number of guide grooves is three, and they are evenly distributed along the circumference of the adjusting ring. The number of fixed shafts is the same as the number of guide grooves and they correspond one-to-one.

[0034] Specifically, the three evenly distributed guide grooves and the fixed shaft form a three-point support structure, which ensures that the force on the lens is completely consistent in the three directions during the up and down movement of the lens. This effectively prevents the lens from tilting due to uneven force and ensures that the lens always remains parallel to the LED light, thereby ensuring the uniformity of the shape and brightness of the light spot and improving the lighting quality.

[0035] Furthermore, the adjusting ring 6 is rotatably disposed within the lamp cavity along the same central axis, and a silicone ring is pressed between the lamp cavity and the adjusting ring 6. The silicone ring causes damping when the adjusting ring 6 rotates relative to the lamp cavity.

[0036] Specifically, the silicone ring is tightly pressed between the inner wall of the lamp cavity and the outer circumference of the adjustment ring. Utilizing the high elasticity and high coefficient of friction of the silicone material, a constant frictional force, or rotational damping, is generated between the adjustment ring and the lamp cavity. When the user rotates the adjustment ring, this damping force provides a moderate operating feel; when the user stops rotating, this damping force can overcome external forces such as lamp vibration and airflow disturbance, preventing the adjustment ring from rotating on its own, thereby stably maintaining the lens in the adjusted position and keeping the focal length unchanged.

[0037] Furthermore, the limiting rod 18 is tapered at the end of the slot. The tapered structure at the end of the limiting rod has a beveled guiding function. When the slot and the limiting rod are aligned, the beveled surface of the tapered rod can guide the limiting rod to automatically center and slide smoothly into the slot, reducing friction and wear between components, making the angle adjustment process smoother, and improving the accuracy and reliability of locking.
