[0002] A track light is a lamp installed on a power track, generally used as a spot light in places where key lighting is required. A conductive metal strip for supplying power to the track light is arranged inside the power track. The track light is provided with conductive sheets corresponding to the conductive metal strips one by one, and a dial is used to drive the conductive sheets to rotate and contact or separate from the conductive metal strips.

[0003] Among them, the track light includes a power connection box slidably arranged on the power track. A suspension rod is rotatably connected to the power connection box, and the lower end of the suspension rod is connected to a lamp body to adjust the irradiation angle. In the related art, two elastic hooks arranged back to back are provided at the upper end of the suspension rod, and an installation through hole matching the diameter size of the suspension rod is opened at the bottom of the power connection box. During assembly, the upper end of the suspension rod is inserted upward from the lower direction of the installation through hole so that the two elastic hooks approach each other and then cross the installation through hole. Subsequently, the elastic hooks recover their elastic deformation and rotatably connect the suspension rod to the power connection box. This rotational connection method relies on the elastic hooks to bear the gravity of the suspension rod and the lamp, with low reliability, and the elastic hooks are deformed due to excessive force, affecting the smoothness of the rotation of the suspension rod.

Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0029] In the description of the present utility model, it should be understood that when it comes to orientation descriptions, for example, terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0030] In the description of the present utility model, the meaning of "several" is one or more, the meaning of "multiple" is two or more. Understandings such as "greater than", "less than", "exceeding", etc. do not include the present number, and understandings such as "above", "below", "within", etc. include the present number. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] See Figures 1 to 4 , the track type power connection box of the present utility model includes: a guide rail box 100 and a suspension rod 200. The inside of the guide rail box 100 has a cavity 110. The bottom wall of the guide rail box 100 is provided with an installation through hole 120 communicating with the cavity 110. At least two first elastic hooks 300 are provided on the inner bottom surface of the guide rail box 100 and are circumferentially distributed around the center of the installation through hole 120 on the outer periphery of the installation through hole 120. The first elastic hook 300 includes an elastic rib plate 310 extending upward and an anti - detachment hook portion 320 formed at the upper end of the elastic rib plate 310. A rotation limiting groove is defined between the anti - detachment hook portion 320 and the inner bottom surface of the guide rail box 100. The suspension rod 200 includes a rod portion 210 passing through the installation through hole 120 and an annular flange 220 provided at the upper end of the rod portion 210 and adapted to the rotation limiting groove. The annular flange 220 can enter the rotation limiting groove after passing downward over the anti - detachment hook portion 320.

[0033] When the suspension rod 200 is assembled to the guide rail box 100, the rod portion 210 is passed downward through the mounting through hole 120 so that the annular flange 220 abuts downward against each first elastic hook 300. During the downward pulling of the annular flange 220, each elastic rib plate 310 undergoes elastic deformation and moves away from each other. After the annular flange 220 passes over the anti-disengagement hook portion 320 and enters the rotation limiting groove, the elastic rib plate 310 then restores its elastic deformation so that the anti-disengagement hook portion 320 prevents the annular flange 220 from popping upward. The annular flange 220 can stably abut against the outer peripheral edge of the mounting through hole 120 to improve the load capacity of the suspension rod 200, which is convenient for production and assembly on the premise of a simple structure, and the suspension rod 200 rotates stably and smoothly.

[0034] It can be understood that the shape of the annular flange 220 is stable. When the annular flange 220 is suspended on the outer peripheral edge of the mounting through hole 120, even if a relatively heavy lamp applies a large pulling force to the suspension rod 200, it will not fall downward through the mounting through hole 120.

[0035] See Figure 3 and Figure 4 , in some embodiments of the present utility model, the mounting through hole 120 is a circular hole, the annular flange 220 has a cylindrical bearing surface 221 matching the circular hole and a convex table surface 222 connected to the upper end of the cylindrical bearing surface 221. A stepped surface is formed between the convex table surface 222 and the cylindrical bearing surface 221 to abut against the outer peripheral edge of the circular hole, and the anti-disengagement hook portion 320 is close to or abuts against the upper surface of the annular flange 220. It can be understood that the cooperation between the circular hole and the cylindrical bearing surface 221 can ensure that the suspension rod 200 can always rotate around the center line of the circular hole and prevent the suspension rod 200 from generating radial movement. The circular stepped surface can contact various positions of the outer peripheral edge of the circular hole, and the radial dimension of the stepped surface can be configured according to the use requirements.

[0036] See Figures 2 to 5 , in some embodiments of the present utility model, a wire passing channel 230 is provided through the middle of the suspension rod 200 along its length direction. An angle limiting portion 223 is protrudingly provided on the outer peripheral wall of the convex table surface 222, and a blocking portion 160 capable of abutting against the angle limiting portion 223 is provided on the inner bottom surface of the guide rail box 100. It can be understood that the wire passing channel 230 is for the wire connecting the lamp body to pass through. When the suspension rod 200 rotates relative to the guide rail box 100 close to 360°, the angle limiting portion 223 abuts against the blocking portion 160 to prevent the suspension rod 200 from continuing to rotate, thereby preventing the wire from being cut off.

[0037] See Figure 2 and Figure 3, in some embodiments of the present utility model, the annular flange 220 has a ring wall 224 located above the convex table surface 222. The center of the ring wall 224 is located on the central axis of the rod portion 210. A plurality of ribs 225 are arranged at equal intervals on the ring wall 224. An elastic clamping portion 140 that abuts against the ring wall 224 is provided inside the cavity 110. It can be understood that there is a card slot between two adjacent ribs 225. During the rotation of the hanging rod 200, the clamping portion 140 is continuously engaged with different card slots, forming a damping feel and a crisp sound, which is beneficial to accurately adjusting the angle of the lamp and also beneficial to improving the user experience.

[0038] See Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present utility model, a strip-shaped slide rail housing 150 is provided on the upper part of the guide rail box 100. First notches 151 are provided on the opposite side walls of the strip-shaped slide rail housing 150. A rotary switch 400 is provided inside the strip-shaped slide rail housing 150. The rotary switch 400 is provided with a first side extension portion 430 and a second side extension portion 440 that face away from each other. A first conductive sheet 510 is provided on the first side extension portion 430. A second conductive sheet 520 and a third conductive sheet 530 are arranged at intervals upward on the second side extension portion 440. When the rotary switch 400 rotates, it drives the first conductive sheet 510 to extend out from one of the first notches 151 and drives the second conductive sheet 520 and the third conductive sheet 530 to extend out from the other first notch 151. It can be understood that the strip-shaped slide rail housing 150 is used for slidingly arranging in the chute of the power track. One of the first conductive sheet 510 and the second conductive sheet 520 is connected to the live wire, the other is connected to the neutral wire, and the third conductive sheet 530 is connected to the ground wire. The lamp is powered on or off through the rotary switch 400.

[0039] See Figure 2 and Figure 6In some embodiments of the utility model, the rotary switch 400 includes a sleeve member 410, a side portion of the sleeve member 410 is provided with a wrench portion 411 extending outside the strip slide rail housing 150, an upper end of the sleeve member 410 is provided with a first side ear 412 and a second side ear 413 which are away from each other, the upper ends of the first conductive sheet 510 and the second conductive sheet 520 are respectively abutted against the first side ear 412 and the second side ear 413, a middle portion of the sleeve member 410 is provided with a plug-in member 420 for pressing the middle portions of the first conductive sheet 510 and the second conductive sheet 520 against the inner wall of the sleeve member 410, the plug-in member 420 has a first lower pressure plate 421 matched with the first side ear 412 and a second lower pressure plate 422 matched with the second side ear 413, and the third conductive sheet 530 is fixed to the plug-in member 420. It can be understood that the first side ear 412 and the first lower pressing plate 421 form a first side extension portion 430 for clamping the first conductive sheet 510 together, and the lower end of the first conductive sheet 510 extends along the inner wall of the sleeve member 410 to the bottom of the sleeve member 410, and the second side ear 413 and the second lower pressing plate 422 form a second side extension portion 440 for clamping the second conductive sheet 520 together, and the lower end of the second conductive sheet 520 extends along the inner wall of the sleeve member 410 to the bottom of the sleeve member 410, and the upper end of the third conductive sheet 530 The first end extends from the top of the second lower pressure plate 422 to the side of the second side extension portion 440, and the lower end of the third conductive sheet 530 passes through the middle of the connector 420 to extend to the bottom of the connector 420 and the sleeve member 410. When the connector 420 is inserted into the sleeve member 410, the first conductive sheet 510 and the second conductive sheet 520 can be positioned and fixed. The first conductive sheet 510, the second conductive sheet 520 and the third conductive sheet 530 are integrated on the rotary switch 400 with a compact and simple structure, and the production and assembly cost is low.

[0040] See also Figure 6 In some embodiments of the present invention, the plug connector 420 has two second elastic hooks 423 disposed opposite to each other, and a clamping groove 424 is disposed between the two second elastic hooks 423 for the third conductive sheet 530 to pass downward. The width direction of the third conductive sheet 530 is disposed along the diverging direction of the two second elastic hooks 423, and the two second elastic hooks 423 are close to each other so that the clamping groove 424 clamps and fixes the third conductive sheet 530. It can be understood that after the two second elastic hooks 423 pass downward through the middle channel of the sleeve member 410, they restore elastic deformation to achieve the connection between the plug connector 420 and the sleeve member 410. At the same time, not only the first conductive sheet 510 and the second conductive sheet 520 are pressed against the inner wall of the sleeve member 410, but also the third conductive sheet 530 is clamped along the width direction of the third conductive sheet 530.

[0041] See also Figure 1 , Figure 2 and Figure 7, in some embodiments of the present utility model, elastic bodies 600 are provided on opposite side walls of the strip-shaped slide rail housing 150 protruding from the strip-shaped slide rail housing 150. The elastic bodies 600 can elastically deform and be tightly fitted with both sides of the track groove. It should be noted that when the track type power connection box is not connected to the power track, the strip-shaped slide rail housing 150 can slide freely on the power track, but the strip-shaped slide rail housing 150 may also fall downward under the action of gravity. The setting of the elastic bodies 600 can avoid this problem.

[0042] See Figure 2 and Figure 7 , in some embodiments of the present utility model, a second notch 152 is respectively provided on opposite side walls of the strip-shaped slide rail housing 150. The elastic body 600 has vertical strips 610 extending along the second notch 152. The vertical strips 610 are arranged with multiple horizontal ridges 611 at intervals in the up and down direction. A horizontal groove is formed between adjacent horizontal ridges 611. A first guiding inclined surface 612 inclined downward is provided on the upper side of the horizontal ridge 611, and a second guiding inclined surface 613 inclined upward is provided on the lower side of the horizontal ridge 611. It should be noted that the depth dimensions of the sliding grooves of power tracks of different specifications are different. The elastic body 600 with the above structure can be adapted to power tracks of different specifications. Moreover, the settings of the first guiding inclined surface 612 and the second guiding inclined surface 613 are beneficial to the plugging and unplugging separation between the track type power connection box and the power track.

[0043] See Figure 3 and Figure 7 , in some embodiments of the present utility model, the elastic body 600 includes a cross plate portion 620 connected between two vertical strips 610. A through hole 621 is provided through the middle of the cross plate portion 620. A threaded post 153 extending downward and opposite to the through hole 621 is provided on the inner top wall of the strip-shaped slide rail housing 150. The width dimension of the second notch 152 is consistent with the width dimension of the vertical strip 610. Specifically, the cross plate portion 620 and the two vertical strips 610 are an integral plastic structure. The cross plate portion 620 and the two vertical strips 610 enclose an "H" shape. The elastic body 600 can be fixed by screwing a screw through the through hole 621 and tightening it on the threaded post 153. The width dimension of the second notch 152 being consistent with the width dimension of the vertical strip 610 prevents the elastic body 600 from deflecting.

[0044] The present utility model also discloses a track light, including the track type power connection box of any of the above technical solutions, which is convenient for production and assembly on the premise of simple structure, and the suspension rod 200 rotates stably and smoothly.

[0045] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0046] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
