Description
Technical Field
[0001] This utility model relates to the field of track lighting technology, specifically to a quick adapter that can be raised and lowered along a track. Background Technology
[0002] Ambient lighting products often require frequent adjustments to the lighting area or range to achieve the desired ambiance. Traditional fixed installation methods for lighting fixtures are insufficient to meet the flexible layout needs of ambient lighting. Therefore, lighting manufacturers have explored track mounting methods, allowing fixtures to be installed in any position based on the track. Track lights mainly consist of two parts: the track and the lighting fixture. The track is typically made of rigid materials such as aluminum or PVC, and at least one connector is installed on the track, along with the connected lighting fixture. The connector can slide along the track, thus adjusting the installation position of the lighting fixture.
[0003] Existing tracks are primarily installed on ceiling surfaces, with light fixtures suspended after being connected to connectors. Similarly, tracks installed on vertical walls or cabinets are typically horizontally oriented, allowing for lateral adjustment of the light fixture's position. However, the installation height of the fixture is fixed due to the track's limitations, resulting in insufficient flexibility. Therefore, existing technologies require improvement and development.

Detailed Implementation
[0021] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.
[0022] like Figure 1-5 As shown, the present invention discloses a quick adapter that can be raised and lowered along a track, comprising a housing 1. The housing 1 is provided with a power connection component and a locking component. The locking component includes a slider 4 and a drive block 41. Slide grooves 18 are symmetrically provided on both side walls of the housing 1, and sliders 4 pass through the slide grooves 18. The outer end face of the slider 4 is provided with a toothed surface 42. A drive block 41 is provided between two sliders 4, and the drive block 41 is respectively connected to the two sliders 4. A connecting rod 43 is provided on the drive block 41, and a fastener 44 is provided on the bottom plate of the housing 1 to be connected to the connecting rod 43.
[0023] like Figure 1 As shown, the quick adapter described in this utility model is used to adapt to the installation of the track 34. In particular, the track 1 can be set vertically on the mounting surface such as a wall, and the quick connector can move up and down along the track 1 to achieve height adjustment.
[0024] Specifically, the housing 1 can be directly inserted into the opening of the track 34. Fasteners 44 drive the connecting rod 43 and the drive block 41, causing the two sliders 4 to bulge outwards relative to the housing 1, creating an expansion effect. The toothed surfaces 42 on the outer ends of the sliders 4 can engage with the linear rails 36 within the track 34, thus fixing the quick connector to the track 34. Furthermore, the electrical connection assembly contacts the electrical rails 35 within the track 34 to form an electrical connection.
[0025] It is understood that the track 34 can also be installed on the ceiling for suspension. After the quick connector is installed on the track 34, the quick connector can also be fixedly connected to the track 34 by the locking component to avoid the quick connector from sliding or loosening.
[0026] The inner end face of the slider 4 is provided with an inclined surface, and the two sides of the driving block 41 are respectively provided with inclined surfaces. The driving block 41 is connected to the slider 4 through the inclined surfaces, thereby driving the two sliders 4 to move along the slide groove 18 towards the outside of the housing 1. The driving block 41 and the slider 4 are paired by the inclined surfaces, so that the displacement direction of the driving block 41 is perpendicular to the displacement direction of the slider 4. Simply put, the connecting rod 43 and the driving block move along the direction perpendicular to the bottom plate of the housing 1, which can drive the two sliders 4 to move to both sides of the housing 1, so that the sliders 4 can protrude from the slide groove 18. The driving block 41 and the two sliders 4 form an approximately expanded structure, so that the sliders 4 are fixedly connected by the tooth surface 42 meshing on the rail 36.
[0027] Furthermore, the fastener 44 is a fastening nut, and a guide seat 45 is provided on the bottom plate of the housing 1. The lower end of the connecting rod 43 passes through the guide seat 45 and extends out of the bottom plate of the housing 1. The fastener 44 is threadedly connected to the lower end of the connecting rod 43. When the fastener 44 is tightened, the connecting rod 43 pulls the drive block 41 towards the bottom plate of the housing 1, causing the two sliders 4 to move to both sides of the housing 1. When the toothed surface 42 on the slider 4 bites the linear guide 36, the fastener 44 can no longer be tightened. Conversely, after the fastener 44 is loosened, the quick connector can be adjusted up and down along the track 34 again to adjust the installation height.
[0028] Preferably, the power connection assembly includes a swing arm 3 and a main control locking rod 2. Both sides of the housing 1 are provided with actuation grooves 11, and the swing arm 3 is provided in the actuation grooves 11. The first end of the swing arm 3 is rotatably connected to the housing 1, and the second end of the swing arm 3 is provided with a conductive element 31. The main control locking rod 2 is rotatably inserted through the housing 1 in a vertical direction. The main control locking rod 2 is provided with an eccentric cam 21, which is paired with the second ends of the two swing arms 3 respectively. The main control locking rod 2 drives the eccentric cam 21 to rotate, which can push the two swing arms 3 to unfold towards the outside of the housing 1 respectively.
[0029] When the quick connector described in this utility model is not installed, the main control locking rod 2 and the eccentric cam 21 are in the initial position, and the two swing arms 3 are housed in the action groove 11. There are no protruding structures on the outer walls of both sides of the housing 1, so the housing 1 can be directly inserted into the track 34 from the opening. When the top surface of the housing 1 touches the track 34, the main control locking rod 2 rotates at a certain angle (usually 90°), which in turn drives the eccentric cam 21 to push the swing arms 3 to unfold outward from the housing 1. After the swing arms 3 extend out of the action groove 11, their second ends protrude from the outer wall of the housing 1. The second ends of the swing arms 3 are fixed on the bottom plates on both sides of the opening of the track 34, and the conductive element 31 contacts the electric rail 35 in the track 34 to form an electrical connection.
[0030] It is understood that the two electrical rails 35 set in the track 34 are used as the live wire and the neutral wire respectively, and the three contact surfaces of the electrical rails 35 with the track 34 are provided with an insulating layer except for the inner side which is exposed. Of course, the electrical rails 35 and the insulating parts can be integrally set and assembled in the groove of the track 34.
[0031] The actuation groove 11 is provided with a pin 12, and the swing arm 3 is rotatably connected to the housing 1 through the pin 12. The housing 1 is provided with two positioning posts 13, and a tension spring 14 is connected between the positioning post 13 and the corresponding swing arm 3. Further, the actuation groove 11 is provided with a pin 12, and the swing arm 3 is rotatably connected to the housing 1 through the pin 12. The housing 1 is provided with two positioning posts 13, and a tension spring 14 is connected between the positioning post 13 and the corresponding swing arm 3. The pin 12 includes structures such as screws, shafts, and rivets, and only requires the first end of the swing arm 3 to be rotatably set in the actuation groove 11 of the housing 1. The positioning post 13 is used to set the tension spring 14 so that the swing arm 3 can automatically retract into the actuation groove 11. That is, when disassembling the quick connector, rotating the main control locking rod 2 in the opposite direction allows both swing arms 3 to retract into the actuation groove 11, thereby allowing the housing 1 to separate from the track 34.
[0032] Specifically, the bottom plate of the housing 1 is provided with a bearing seat 15, and an eccentric cam 21 is rotatably mounted on the bearing seat 15. The main control locking rod 2 is movably inserted through the bearing seat 15. The top plate of the housing 1 is provided with a countersunk groove 16, and a central through hole 17 is provided in the countersunk groove 16. A cross groove is provided on the bottom surface of the countersunk groove 16. A locking head 22 is provided in the countersunk groove 16, and the upper end of the main control locking rod 2 is movably inserted through the central through hole 17, and the upper end of the main control locking rod 2 is fixedly connected to the locking head 22. It can be understood that the rotation of the main control locking rod 2 on the bearing seat 15 can drive the eccentric cam 21 to press the swing arm 3, thereby converting the rotational motion of the main control locking rod 2 into the linear motion of the swing arm 3. In particular, after the main control locking rod 2 rotates to its position, the eccentric cam 21 always contacts the swing arm 3 to prevent it from loosening, avoiding the problem of poor contact between the conductive part 31 and the electric rail 35.
[0033] Furthermore, the main control locking rod 2 can move vertically up and down on the housing 1. When the main control locking rod 2 moves upward a certain distance, the locking head 22 disengages from the cross groove. Only then can the main control locking rod 2 rotate to drive the swing arm 3 to extend or retract. After the swing arm 3 extends, the main control locking rod 2 returns to its original position under gravity. At this point, the locking head 22 can re-engage into the cross groove, thereby locking the main control locking rod 2.
[0034] It is understood that the lock head 22 can be a single-line structure or a cross structure. Furthermore, the main control lock rod 2 and the transmission component 21 are fixedly connected. When the main control lock rod 2 slides down, the transmission component 21 rests on the shaft seat 15 to limit the main control lock rod 2.
[0035] The swing arm 3 is provided with a wiring groove 32. The first end of the wiring groove 32 penetrates the end face of the second end of the swing arm 3, and the second end of the wiring groove 32 penetrates the inner sidewall of the swing arm 3. The first end of the conductive element 31 is provided with an elastic spring 33. The conductive element 31 is embedded in the wiring groove 32 so that the elastic spring 33 covers the outer side of the second end of the swing arm 3. Preferably, the conductive element 31 is provided with an elastic spring 33, which can extend the stroke of the swing arm 3 and avoid structural and assembly tolerance problems. Furthermore, after the housing 1 slides along the track 34 to adjust its position, the elastic spring 33 can automatically conform to the electric track 35 to avoid poor contact.
[0036] The housing 1 contains a control circuit board 23, which is connected to two conductive components 31 via leads. The lower end of the main control locking rod 2 is provided with an adapter 24, and the main control locking rod 2 contains a wire hole 25. The lower end of the wire hole 25 passes through the adapter 24. The side wall of the main control locking rod 2 is provided with a wire inlet 26. The conductive components 31 are used to install and fix the elastic spring 33 through the wiring groove 32. The two conductive components 31 pass through the swing arm 3 and are set inside the housing 1, and are then connected to the control circuit board 23 via leads. The leads on the control circuit board 23 pass through the wire inlet 26 and the wire hole 25 and are then connected to the adapter 24.
[0037] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
