Description

Technical Field

[0001] This utility model relates to the field of track lighting technology, and in particular to a track-type power supply box and lighting fixture. Background Technology

[0002] Track lights are lights installed on a track, allowing them to slide along the track to change their position and adjust the lighting area. Conductive metal strips are located on both sides inside the track, receiving a power supply voltage. The track light is typically integrated with a driver power supply box, which is also a power converter. The driver power supply box has rotatable conductive copper plates and limiting blocks at its connectors. During installation, rotating the conductive copper plates and limiting blocks on the driver power supply box causes the limiting blocks to engage with the strips in the track, securing the light and simultaneously bringing the conductive copper plates into contact with the conductive metal strips inside the track, thus powering the track light. However, current track-type power supply boxes have a power distribution mechanism, requiring users to switch circuits through this mechanism, which is inconvenient.

[0034] In Embodiment 1 of this application:

[0035] The rotary shifting device 22 includes a support 221, a turntable 222, a rotating connecting mechanism 223, an anti-rotation mechanism 224, a toggle mechanism 225, and a latching mechanism 226. The support 221 is located on one inner wall of the housing 1. The phase power take-up component 25 is mounted on the support 221. The turntable 222 is located on the side of the phase power take-up component 25 facing away from the support 221. The latching mechanism 226 is located on the side of the turntable 222 facing the phase power take-up component 25 and engages with it. The other end of the rotating connecting mechanism 223 is connected to the support 221 or the housing 1. The rotating mechanism 224 connects the turntable 222 and the support 221. The actuating mechanism 225 is located on the housing 1 and connected to the turntable 222. The turntable 222 is rotatably connected relative to the housing 1 through the rotating connection mechanism 223. The latching mechanism 226 connects the phase power take-off component 25 and the turntable. Actuating the actuating mechanism 225 drives the turntable 222 to rotate. The phase power take-off component 25 rotates synchronously with the turntable 222. When one end of the phase power take-off component 25 is electrically connected to any of the live wire power take-off components 27, the anti-rotation mechanism 224 restricts the rotation of the turntable 222 so that the rail-type power box is maintained at a certain position.

[0036] The support 221 includes an outer sleeve, and the rotating connection mechanism 223 includes multiple arc-shaped protrusions. The multiple arc-shaped protrusions surround the turntable 222, and each arc-shaped protrusion abuts against the inner side of the outer sleeve. The rotating connection between the turntable 222 and the support 221 is achieved through the abutment of the multiple arc-shaped protrusions against the inner side of the outer sleeve. The structure is simple.

[0037] The latching mechanism 226 includes a limiting post 2261, an inner sleeve 2262, and multiple hooks 2263. The limiting post 2261 is disposed on the turntable 222, and the multiple hooks 2263 are arranged around the limiting post 2261. The inner sleeve 2262 is disposed inside the outer sleeve. The limiting post 2261 passes through the phase power take-up component 25 and engages with the inner sleeve 2262. The multiple hooks 2263 are respectively engaged with two sides of the phase power take-up component 25. At the end, the limiting post 2261 restricts the phase power taking component 25 from moving radially along the turntable 222, and the multiple hooks 2263 restrict the phase power taking component 25 from rotating axially along the turntable 222. Together, they fix the phase power taking component 25. At the same time, the cooperation between the limiting post 2261 and the inner sleeve 2262 further improves the stability of the rotational connection between the turntable 222 and the support 221, as well as the smoothness during rotation.

[0038] The anti-rotation mechanism 224 includes an extension block 2241, an anti-rotation block 2242, and multiple slots 2243. The multiple slots 2243 are sequentially arranged on the outer sleeve. The extension block 2241 is located on the side of the turntable 222 facing the outer sleeve, and the anti-rotation block 2242 is located on the side of the extension block 2241. The cross-sectional shape of the anti-rotation block 2242 is triangular. The anti-rotation block 2242 engages with any of the slots 2243. When the turntable 222 drives the extension block 2241 to rotate, the anti-rotation block 2242 is subjected to the force of any of the slots 2243. The anti-rotation block 2242 compresses the extension block 2241 to deform so that it disengages from any of the slots 2243 and enters the next slot 2243. The structure is simple and easy for users to rotate and adjust.

[0039] The actuating mechanism 225 includes an arc-shaped groove 2251 and a toggle block 2252. Two arc-shaped grooves 2251 and two toggle blocks 2252 are respectively arranged on the housing 1 along the axis of the turntable 222. Two toggle blocks 2252 are symmetrically arranged on the turntable 222 along the axis of the turntable 222. Each toggle block 2252 passes through the arc-shaped groove 2251. Rotating the toggle block 2252 drives the turntable 222 to rotate. The arc-shaped groove 2251 is positioned opposite the toggle block 2252. The rotation path of 2 is limited, and the rotation direction of the turntable 222 is restricted to improve the stability of the turntable 222 during rotation. The arc groove 2251 has an angled edge 2253 on the edge facing away from the turntable 222, and the actuating block 2252 has multiple protrusions 2254 on the side facing away from the turntable 222. The angled edge 2253 is set to avoid the position of the actuating block 2252, making it easier for the user to move the actuating block 2252. The protrusions 2254 can prevent the user's hand from slipping on the actuating block 2252.

[0040] The actuating mechanism 225 further includes a rotating column 2255, a through hole 2256, and an actuating groove 2257. The through hole 2256 is provided on the housing 1. The rotating column 2255 passes through the through hole 2256 and is connected to the turntable 222. The actuating groove 2257 is provided on the side of the rotating column 2255 facing away from the turntable 222. In the embodiments of this application, the user can also use a tool to insert into the actuating groove 2257 to rotate the turntable. At the same time, the cooperation of the rotating column 2255 and the through hole 2256 further restricts the rotation of the turntable 222.

[0041] The track-mounted power box also includes a ground wire conductor 5, which is located inside the box body 1. One end of the ground wire conductor 5 is electrically connected to the power conversion module 3, and the other end of the ground wire conductor 5 extends outside the box body 1. The ground wire conductor 5 is electrically connected to the track to prevent electric shock to the user during use.

[0042] The power switch 21 includes a rotating block 211, a lever 212, a protrusion 213, an unlocking positioning groove 214, and a locking positioning groove 215. The rotating block 211 is rotatably disposed inside the housing 1. The neutral wire power supply component 26 and multiple live wire power supply components 27 are all disposed on the rotating block 211. One end of the lever 212 is connected to the rotating block 211, and the other end of the lever 212 passes through the housing 1. The protrusion 213 is disposed on the lever 212. The unlocking positioning groove 214 and the locking positioning groove 215 are respectively disposed on the outer side of the housing 1. The protrusion 213 engages with the unlocking positioning groove 214 or the locking positioning groove 215. The lever 212 drives the rotating block 211 to rotate, and the protrusion 213 engages with the unlocking positioning groove 214 or the locking positioning groove 215, ensuring the structural stability of the rail-type power box and the rail in the locked or unlocked state.

[0043] In Embodiment 2 of this application:

[0044] The actuating mechanism 225 further includes a groove 2258, a connecting groove 2259, and a plurality of serrations 2250. The groove 2258 is located on the bottom of the housing 1. The connecting groove 2259 is located on the groove 2258 and communicates with the interior of the housing 1. A portion of the turntable 222 passes through the connecting groove 2259 and protrudes outside the housing 1. The plurality of serrations 2250 are arranged sequentially around the outer periphery of the turntable 222. When the turntable 222 passes through the connecting groove 2259 and protrudes outside the housing 1, the groove... 2258 forms a clearance on the box body 1 to ensure that the turntable 222 is exposed while preventing the turntable 222 from protruding from the plane where the bottom of the box body 1 is located, and multiple serrations 2250 are provided to facilitate operation by the operator; the rotating connection mechanism 223 also includes a rotating sleeve and a rotating rod. The rotating sleeve is located on the side of the box body 1 away from the support 221, and the rotating rod is located on the turntable 222 and passes through the rotating sleeve to realize the rotating connection between the turntable 222 and the box body 1;

[0045] In addition, the anti-rotation mechanism 224 also includes the extension block 2241, the anti-rotation block 2242, and a plurality of arc-shaped protrusions.
