Description

Technical Field

[0001] This utility model relates to the field of track lighting technology, specifically to a quick connector for track lights. 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] During on-site track installation, connectors are first installed from the ends of the track according to requirements. End caps are installed at both ends of the track to prevent connector detachment; one of these end caps also serves as a power input, electrically connecting to the conductive structure inside the track. The track is then fixed to the ceiling, and the light fixtures are connected to the connectors to complete the installation. It is evident that once the track lighting installation is complete, the number of connectors on the track is fixed. Later, if additional connectors need to be added or replaced for maintenance, operators must climb to remove the end caps from the track, a cumbersome and inconvenient process.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0022] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-4 As shown, the present invention provides a quick connector for track lights, comprising a housing 1 and a main control locking rod 2. The housing 1 has two side walls each equipped with an action groove 11 communicating with its inner cavity. A swing arm 3 is provided within the action groove 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 equipped with a conductive element 31. The main control locking rod 2 is rotatably inserted vertically through the housing 1. A transmission element 21 is provided on the main control locking rod 2, and the transmission element 21 is paired with the second ends of the two swing arms 3 respectively. The main control locking rod 2 drives the transmission element 21 to rotate, which in turn pushes the two swing arms 3 to extend outwards from the housing 1.

[0024] like Figure 5 As shown, the track 34 for installing track lights has a slide and an opening, and electric rails 35 are installed on the inner walls on both sides of the slide. The track 34 is fixed to the ceiling surface.

[0025] When the quick connector described in this utility model is not installed, the main control locking rod 2 and the transmission component 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°), thereby driving the transmission component 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 component 31 contacts the electrical rail 35 in the track 34 to form an electrical connection.

[0026] 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.

[0027] Furthermore, a pin 12 is provided within the actuation groove 11, and the swing arm 3 is rotatably connected to the housing 1 via the pin 12. Two positioning pins 13 are provided within the housing 1, and tension springs 14 connect the positioning pins 13 to their corresponding swing arms 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 positioned within the actuation groove 11 of the housing 1. The positioning pins 13 are used to accommodate the tension springs 14, allowing the swing arms 3 to 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 detach from the opening of the track 34.

[0028] Furthermore, the transmission component 21 is used to convert the rotational motion of the main control locking rod 2 into the linear motion of the swing arm 3. The transmission component 21 can be an existing structure such as a cam, connecting rod, or slider.

[0029] Preferably, the bottom plate of the housing 1 is provided with a bearing seat 15, the transmission component 21 is disposed on the bearing seat 15, the main control locking rod 2 is movably inserted through the bearing seat 15, and the main control locking rod 2 is fixedly connected to the transmission component 21; both ends of the transmission component 21 are provided with eccentric cams 22, and the two eccentric cams 22 are respectively in contact with the corresponding swing arms 3. It can be understood that the transmission component 21 and the eccentric cams 22 at both ends are an integral structure. The rotation of the main control locking rod 2 can drive the eccentric cams 22 to squeeze the swing arms 3, thereby converting the rotational action of the main control locking rod 2 into the linear action of the swing arms 3. In particular, after the main control locking rod 2 rotates to the position, the eccentric cams 22 always contact the swing arms 3 to prevent them from loosening, avoiding the problem of poor contact between the conductive component 31 and the electric rail 35.

[0030] Furthermore, the top plate of the housing 1 is provided with a countersunk groove 16, a central through hole 17 is provided in the countersunk groove 16, and a cross groove is provided on the bottom surface of the countersunk groove 16; a locking member 23 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 member 23. The main control locking rod 22 can move up and down vertically on the housing 1. When the main control locking rod 22 moves upward a certain distance, the locking member 23 disengages from the cross groove. At this time, the main control locking rod 22 can rotate to drive the swing arm 3 to extend or retract. When the swing arm 3 extends, the main control locking rod 2 returns to its original position under the action of gravity. At this time, the locking member 23 can re-engage into the cross groove, thereby locking the main control locking rod 2.

[0031] It is understood that the lock head 23 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.

[0032] 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 fit against the electric track 35 to avoid poor contact. The conductive element 31 is installed and fixed to the elastic spring 33 through the wiring groove 32 and connected to the housing 1. The housing 1 is provided with a control circuit board 4, which is connected to the two conductive elements 31 through leads. The lower end of the main control locking rod 2 is provided with an adapter 24, and the control circuit board 4 is connected to the adapter 24 through wires.

[0033] The main control locking rod 2 is provided with a wire hole 25, and 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 wire passes through the wire hole 25, one end of the wire is connected to the adapter 24, and the other end of the wire passes through the wire inlet 26 and connects to the control circuit board 4.

[0034] 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.
