Description
Technical Field
[0001] This utility model relates to the field of lighting technology, specifically to an adjustable track light structure. Background Technology
[0002] LEDs, as solid-state semiconductor devices that can directly convert electrical energy into visible light, have the characteristics of low energy consumption, long optical life, and environmental friendliness, and have been widely replaced by traditional light source lighting devices. For LED spotlights, different applications require different illumination ranges and angles, which necessitates that LED spotlights have adjustable illumination angles and ranges.
[0003] Currently, LED spotlights on the market mainly consist of a lamp body and a base, connected by a hinge structure. This allows for adjustment of the lamp's projection angle after installation. Once the angle is adjusted, the hinge structure needs to be locked to prevent the lamp body from deflecting. However, existing lamps use screws for hinge fastening. Due to uneven tightening force, the lamp body's turning motion is inconsistent, with some being loose and others tight, resulting in an unsmooth experience. Furthermore, after repeated adjustments, wear on the hinge's mating surfaces or loosening of the screws can cause the lamp body's adjustment function to fail, affecting the product's lifespan.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content
[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably structured, stable and reliable adjustable angle track light structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The present invention discloses an adjustable track light structure, comprising a light body, a track connector, and a rotating arm. The first end of the rotating arm is fixedly connected to the track connector, and the second end of the rotating arm is connected to the light body via a hinge structure. The hinge structure includes a shaft head, a bracket, and a fastener. The shaft head is disposed on the second end of the rotating arm, and the bracket is fixedly disposed on the light body. The fastener passes through the shaft head and the bracket to allow them to be rotatably connected, and an anti-slip pad and a damping pad are provided between the shaft head and the bracket.
[0008] According to the above scheme, the bracket is provided with a first hinge plate and a second hinge plate, which are spaced apart to form a socket between them; both the first hinge plate and the second hinge plate are provided with through holes, and the shaft head is provided with a central hole. The fastener passes through the central hole and the two through holes, so that the shaft head can be rotatably inserted into the socket.
[0009] According to the above scheme, the fastener includes a bolt and a lock nut. The threaded end of the bolt passes through the through hole on the first hinge plate, the center hole, and the through hole on the second hinge plate in sequence before being screwed onto the lock nut.
[0010] According to the above scheme, anti-slip pads are provided between the first end face of the shaft head and the first hinge plate, and between the second end face of the shaft head and the second hinge plate; damping pads are provided between the first hinge plate and the bolt head, and between the second hinge plate and the anti-loosening nut.
[0011] According to the above scheme, grooves are provided on both the first and second end faces of the shaft head, and fasteners are provided on the anti-slip pad. The fasteners are inserted into the grooves to make the anti-slip pad and the shaft head cooperate and connect.
[0012] According to the above scheme, the anti-slip pad is made of stainless steel.
[0013] According to the above scheme, the damping pad includes an arc-shaped pad and a spring pad.
[0014] According to the above scheme, the lamp body is provided with a mounting groove, the bracket is embedded in the mounting groove, and the bracket is riveted to the lamp body by a number of screws.
[0015] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure. The shaft head and the bracket are connected by fasteners and can rotate relative to each other. The damping pad can control the fastening force of the fasteners and prevent the shaft head and the bracket from being too tight, which would affect the flexibility of angle adjustment.

[0021] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.
[0022] like Figure 1-3 As shown, the adjustable track light structure of this utility model includes a light body 1, a track connector 2, and a rotating arm 21. The first end of the rotating arm 21 is fixedly connected to the track connector 2, and the second end of the rotating arm 21 is connected to the light body 1 through a hinge structure. The hinge structure includes a shaft head 22, a bracket 3, and a fastener. The shaft head 22 is disposed on the second end of the rotating arm 21, and the bracket 3 is fixedly disposed on the light body 1. The fastener passes through the shaft head 22 and the bracket 3 to allow them to be rotatably connected, and an anti-slip pad 31 and a damping pad 32 are provided between the shaft head 22 and the bracket 3.
[0023] It is understood that the fastener is set as an axle between the shaft head 22 and the bracket 3, so that the two can rotate relative to each other. The shaft head 22 is set on the rotating arm 21 of the track joint 2, and the bracket 3 is set on the lamp body 1, so that the lamp body 1 can rotate relative to the track joint 2. That is, the hinge structure enables the lamp body 1 to have an angle adjustment function.
[0024] Furthermore, after the angle of the lamp body 1 is adjusted, the fastener can lock the rotational freedom between the shaft head 22 and the bracket 3, preventing the lamp body 1 from rotating. The locking function of the fastener can be achieved through friction, that is, there is friction between the shaft head 22 and the bracket 3, and this friction is proportional to the fastening force provided by the fastener. Therefore, the damping pad 32 can control the fastening force of the fastener, preventing the fastener from being too tight, which would make it difficult to adjust the lamp body 1, and preventing the fastener from being too loose, which would result in insufficient friction and make it impossible to limit the angle of the lamp body 1.
[0025] Furthermore, the shaft head 22 and the bracket 3 are separated by an anti-slip pad 31. The anti-slip pad 31 is made of stainless steel and rotates relative to the bracket 3 to prevent wear of the shaft sleeve 22 from causing the lamp body 1 to loosen.
[0026] Specifically, the bracket 3 is provided with a first hinge plate 33 and a second hinge plate 34, which are spaced apart to form a socket 35 between them. Both the first hinge plate 33 and the second hinge plate 34 have through holes 36, and the shaft head 22 has a central hole 23. The fastener passes through the central hole 23 and the two through holes 36, allowing the shaft head 22 to rotatably fit into the socket 35. The first hinge plate 33, the second hinge plate 34, and the bracket 3 form a U-shaped opening structure, which can be bent into shape. The through holes 36 and the central hole 23 are concentrically arranged after pairing, and the fastener passing through the through holes 36 and the central hole 23 allows the shaft head 22 to rotate relative to the bracket 3. Furthermore, the shaft head 22 has surface contact with the first hinge plate 33 and the second hinge plate 34, which generates friction to prevent the hinge structure from rotating.
[0027] The fasteners include a bolt 11 and a lock nut 12. The threaded end of the bolt 11 passes sequentially through the through hole 36 on the first hinge plate 33, the center hole 23, and the through hole 36 on the second hinge plate 34 before being screwed onto the lock nut 12. The lock nut 12 has self-locking properties to prevent the fasteners from loosening and causing the hinge structure to fail.
[0028] Anti-slip pads 31 are provided between the first end face of the shaft head 22 and the first hinge plate 33, and between the second end face of the shaft head 22 and the second hinge plate 34; damping pads 32 are provided between the first hinge plate 33 and the screw head of the bolt 11, and between the second hinge plate 34 and the anti-loosening nut 12. The damping washer 32 is used to control the tightening force of the fastener. Specifically, the damping washer 32 includes an arc-shaped washer and a spring washer. When the anti-loosening nut 12 is tightened with a torque wrench using 12 Nm, the shaft head 22, the anti-slip washer 31, and the first hinge plate 33 and the second hinge plate 34 on the bracket 3 are clamped together. The anti-slip washer 31 is integrated with the shaft head 22. When the lamp body 1 rotates, the anti-slip washer 31 slides relative to the first hinge plate 33 or the second hinge plate 34. The stainless steel anti-slip washer 31 can provide sufficient friction to form a self-locking mechanism and sufficient wear resistance to ensure that the hinge structure remains reliable even after the lamp body 1 has been rotated multiple times (tested with a strength of 2000 times), which is equivalent to lifelong stability. It is understood that 304 stainless steel is used to make the anti-slip washer 31, which makes it more corrosion resistant, thereby ensuring the feel and stability of the lamp during adjustment.
[0029] The first and second end faces of the shaft head 22 are both provided with grooves 24. A fastener 37 is provided on the anti-slip pad 31, which engages with the groove 24 to connect the anti-slip pad 31 to the shaft head 22. The anti-slip pad 31 is fastened to the first and second end faces of the bushing 22 by the fastener 37, replacing the friction between the shaft head 22 and the first hinge plate 33 and second hinge plate 34 on the bracket 3, thus preventing wear on the shaft head 22. Preferably, the rotating arm 21 and the shaft head 22 are made of zinc alloy to ensure structural strength.
[0030] The lamp body 1 is provided with a mounting groove 13, and the bracket 3 is embedded in the mounting groove 13. The bracket 3 is riveted to the lamp body 1 by a number of screws 14.
[0031] 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.
