[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts the linkage design of the ring and the swing arm and is adaptive to the wire. When the track strip rotates, the ring will slide vertically along the through groove of the vertical plate, so that the length of the wire originally wound in a U shape in the ring is automatically adjusted. When the track strip is tilted upward, the ring moves up to stretch the U-shaped bottom of the wire, and the bending curvature of the wire is reduced; when the track strip is tilted downward, the ring moves down to restore the U-shaped structure of the wire and shorten the length. This mechanism of automatically adjusting the extension state of the wire with the change of angle completely changes the bending problem caused by the fixed connection of the wire in traditional track lamps. The present invention keeps the wire in a natural stretched state through mechanical linkage, and the bending stress is evenly distributed in the sliding process of the ring, which fundamentally avoids the problem of aging and breakage of the wire due to frequent bending, and significantly extends the service life of the lamp.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] Example 1: like Figures 1 to 11 As shown, a track lighting power box includes a power box shell 1.

[0022] A track socket 13 for adjusting the angle is rotatably mounted on the power box housing 1. A wire 15 is connected to the lead interface on the back of the track socket 13. The wire 15 passes through the power box housing 1. A vertically sliding ring 2 is installed inside the power box shell 1, and the wire 15 is movable through the inside of the ring 2. A connecting block 21 is installed on the ring 2, and a connecting plate 23 is installed on the connecting block 21. A swing arm 24 is rotatably installed between the connecting plate 23 and the back of the track strip 13. When the track strip 13 is adjusted in angle, the swing arm 24 drives the ring 2 to move, so that the length of the wire 15 is adaptively adjusted automatically, avoiding damage to the wire due to excessive bending due to angle adjustment, and extending the service life of the wire.

[0023] A rocker arm 311 is mounted at the rotation center of the track strip 13. A power storage cover 3 is mounted on the rocker arm 311. A latching rod 32 is inserted into the power storage cover 3, and a return spring 323 is interlocked between the latching rod 32 and the power storage cover 3. The latching rod 32 corresponds to a plurality of pairs of latching holes 321 defined in the sidewall of the power supply box housing 1 and is used to position the track strip 13. The engagement of the latching rod 32 with the latching holes 321 allows the track strip 13 to be stably fixed at various angles, meeting various lighting requirements and enhancing the flexibility of the lamp.

[0024] like Figures 1 to 11 As shown, in a specific embodiment, a base 11 is installed at the bottom of the power box housing 1, and mounting plates 12 are symmetrically provided at both ends of the power box housing 1. The mounting plates 12 are integrally cast with the power box housing 1. A countersunk groove 121 is provided on the mounting plate 12, and two vertical strip grooves 122 are provided on the countersunk groove 121. A circular hole 123 is provided on the strip groove 122. The circular hole 123 facilitates connection with bolts in the later stage. The integrally cast mounting plate 12 and the power box housing 1 have a more stable structure. The provision of the countersunk groove 121, the strip groove 122, and the circular hole 123 facilitates the fixing of the bolts during installation. At the same time, the strip groove 122 can adapt to a certain installation position deviation, thereby improving the convenience of installation.

[0025] like Figures 1 to 11As shown, further, positioning shafts 131 are installed at both ends of the track strip 13. The positioning shafts 131 movably penetrate the side walls of the power box housing 1. A positioning seat 132 is installed on the side walls of the power box housing 1. The positioning seat 132 is rotatably connected to the positioning shaft 131. A curved surface 141 is provided on the top of the track strip 13. The curved surface 141 closely fits the side walls of the curved inner cavity 14 provided within the power box housing 1. A handle 133 is installed on the surface of the track strip 13. The rotational connection between the positioning shaft 131 and the positioning seat 132 allows the track strip 13 to rotate more smoothly. The close fit between the curved surface 141 and the curved inner cavity 14 improves the stability of the track strip 13 during rotation and reduces shaking. The provision of the handle 133 facilitates the user to operate the track strip 13 to adjust its angle.

[0026] like Figures 1 to 11 As shown, the track strip 13 is further provided with a slot 161, and a slide 16 is mounted on the bottom of the power box housing 1. The slide 16 slides in the slot 161, and a slide bar 162 is mounted on the slot 161. The slide bar 162 and the slot 161 are both arc-shaped, and the slide bar 162 movably extends through the slide 16. A compression spring 163 is sleeved on the slide bar 162, one end of which is engaged with the slot 161, and the other end of which is engaged with the side wall of the slide 16. The sliding of the slide 16 in the slot 161 and the engagement of the compression spring 163 provide elastic support when the track strip 13 rotates, further enhancing the stability of the track strip 13 during rotation and reducing angular deviation caused by factors such as vibration.

[0027] Example 2: The difference between the above embodiment and this embodiment is that: Figures 1 to 11 As shown, the inner sidewall of the collar 2 is provided with a chamfer 211, which prevents friction between the collar 2 and the wire 15, potentially damaging the wire 15. A vertical plate 22 is installed vertically through the interior of the power box housing 1. This plate 22 is provided with a through slot 221, and the connecting block 21 is slidably mounted on the through slot 221. A limit rod 222 is vertically mounted on the through slot 221. A limit spring 223 is sleeved on the sidewall of the limit rod 222. The top of the limit spring 223 engages the bottom of the through slot 221, and the bottom of the limit spring 223 engages the connecting block 21. The chamfer 211 effectively reduces friction between the collar 2 and the wire 15, protecting it from damage. The combination of the limit rod 222 and the limit spring 223 limits and cushions the sliding movement of the connecting block 21, ensuring smoother movement of the collar 2 and better adapting to adjustments in the length of the wire 15.

[0028] like Figures 1 to 11As shown, in a specific embodiment, side panels 231 are mounted at both ends of the connecting plate 23. The side panels 231 are vertically slidably connected to the side walls of the vertical panel 22. A fixing seat 232 is mounted on the connecting plate 23, which is rotatably connected to one end of the swing arm 24. A synchronization shaft 241 is mounted at the rotational center of the other end of the swing arm 24. Both ends of the synchronization shaft 241 are mounted in mounting slots 242 defined on the back of the track strip 13. The vertical sliding connection between the side panels 231 and the vertical panel 22 ensures the stability of the movement of the connecting plate 23. The rotational connection between the fixing seat 232 and the swing arm 24, and the coordination between the synchronization shaft 241 and the mounting slot 242, enable the accurate transmission of the angle adjustment of the track strip 13 to the collar 2, thereby achieving automatic adjustment of the length of the wire 15.

[0029] Example 3: The difference between the above embodiment and this embodiment is that: Figures 1 to 11 As shown, an L-shaped bracket 31 is mounted on the side wall of the energy storage cover 3. The end of the L-shaped bracket 31 is interconnected with the rocker arm 311. A baffle 322 is slidably installed inside the energy storage cover 3. One end of the baffle 322 is interconnected with the clamping rod 32. A return spring 323 is clamped between the other end of the baffle 322 and the inner wall of the energy storage cover 3. The compression direction of the return spring 323 and the movement direction of the clamping rod 32 are both in a straight line. The L-shaped bracket 31 can firmly mount the energy storage cover 3 on the rocker arm 311, ensuring the stability of the fit between the clamping rod 32 and the clamping hole 321. The return spring 323 and the movement direction of the clamping rod 32 are in a straight line, making the reset action of the clamping rod 32 smoother and more accurate, ensuring the positioning effect of the track strip 13 after the angle is adjusted.

[0030] like Figures 1 to 11 As shown, in a specific embodiment, the card rod 32 movably passes through the rocker arm 311, and several pairs of card holes 321 are arc-shaped, and the center of curvature of the arc surrounded by the several pairs of card holes 321 is the same as the rotation center of the track socket 13. The side wall of the card rod 32 is installed with a top plate 332, and the side wall of the power box shell 1 is horizontally movably installed with a push rod 331. The end of the push rod 331 located inside the power box shell 1 is installed with a push plate 33, and the push plate 33 is arc-shaped. The side wall of the push plate 33 fits tightly with the side wall of the top plate 332. Pressing the push rod 331 drives the push plate 33 to move, thereby driving the card rod 32 installed with the top plate 332 to move and separating the card hole 321. The locking hole 321 is arc-shaped and the center of curvature is the same as the rotation center of the track strip 13, so that the locking rod 32 can be accurately inserted into the corresponding locking hole 321 when the track strip 13 is rotated to any target angle, achieving stable positioning. The setting of the push rod 331, the push plate 33, and the top plate 332 makes the unlocking operation more convenient. The user only needs to press the push rod 331 to easily release the lock between the locking rod 32 and the locking hole 321, which is convenient for angle adjustment.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention further discloses a lamp, including the above-mentioned track lamp power box, with a plurality of pairs of track sockets 41 slidingly provided on a track socket strip 13, each track socket 41 being plugged into a lamp body 4, and the track socket strip 13, the track sockets 41, and the internal circuits of the lamp body 4 being interconnected. The track sockets 41 can slide on the track socket strip 13, making it convenient for users to adjust the position of the lamp body 4 according to actual needs. The arrangement of multiple pairs of track sockets 41 can meet the installation requirements of multiple lamp bodies 4, making the arrangement of the lamps more flexible and adaptable to different lighting scenarios.

[0032] The implementation principle of a track lamp power box and lamp of the present invention is as follows: When it is necessary to adjust the pitch angle of the lamp body 4, the operator only needs to adjust the angle of the track strip. First, the operator's finger presses the push rod 331 extending horizontally from the side wall of the power box shell. As the push rod 331 moves into the power box shell 1, the push rod 331 drives the push plate 33 to move, and the push plate 33 will push the top plate 332, so that the locking rod 32 overcomes the elastic force of the return spring 323 and slides toward the inside of the energy storage cover 3. The wedge-shaped head at the front end of the locking rod 32 gradually disengages from the locking hole 321 on the side wall of the shell, completing the unlocking action. In the above process, the return spring 323 becomes compressed, and the compressed return spring 323 facilitates the subsequent reset operation.

[0033] After unlocking, pull the handle 133 on the surface of the track strip 13 to rotate the track strip 13 around the positioning shaft 131. Both ends of the positioning shaft 131 pass through the side wall of the shell and form a bearing connection with the positioning seat 132 to ensure smooth rotation.

[0034] During the rotation of the track strip 13, the curved surface 141 at the top of the track strip 13 slides within the curved inner cavity 14 of the housing. Simultaneously, the slide 16 at the bottom moves along an arc within the slide slot 161. The slide rod 162 penetrates the slide 16 and compresses the compression springs 163 on either side, maintaining the strip's stability through elastic force. Because the track strip 13 is slidably mounted with several pairs of track sockets 41, each plugged into the lamp body 4 and interconnected by internal circuitry, changes in the angle of the track strip 13 directly drive the lamp body 4 to rotate synchronously, achieving pitch adjustment.

[0035] During the rotation process, the synchronizing shaft 241 in the mounting slot 242 on the back of the track strip 13 drives the swing arm 24 to move. The other end of the swing arm 24 is hinged to the fixing seat 232 mounted on the connecting plate 23, thereby driving the side panels 231 at both ends of the connecting plate 23 to slide along the vertical guide rails on the side walls of the vertical plate 22.

[0036] The connecting block 21 on the connecting plate 23 then moves up and down within the slot 221 of the vertical plate 22. The limiting rod 222 in the slot 221 penetrates the connecting block 21 and compresses the limiting spring 223, forming an elastic buffer. The collar 2 on top of the connecting block 21 moves synchronously, and the wire 15, originally wrapped in a U-shape, penetrates the chamfer 211 on the inside of the collar 2. As the collar 2 moves upward, the depth of the U-shaped wire 15 becomes shallower, and the length of the wire 15 inside the collar 2 increases. The curved portion gradually stretches, allowing the overall length of the wiring harness to adapt to the changes in the rotation angle of the power strip, preventing damage to the wire due to excessive bending.

[0037] When the track strip 13 is rotated to the target angle, release the finger pressing on the push rod 331, and the return spring 323 in the energy storage cover 3 will recover its deformation, pushing the baffle 322 and driving the locking rod 32 toward the side wall of the housing. Because the locking holes 321 are arranged in an arc shape and the center of curvature coincides with the rotation center of the strip, the front end of the locking rod 32 will precisely insert into the corresponding locking hole 321. The wedge-shaped mating surface of the locking rod 32 and the locking hole 321 generates a self-locking force, stably fixing the track strip 13 at the adjusted angle. At the same time, the compression springs 163 on both sides of the slide 16 also assist in positioning through elastic force, ensuring that the strip will not shift in angle due to factors such as vibration during use.
