Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an adjustable lighting structure. Background Technology

[0002] In the present technology, lamps, as a common lighting device, are widely used in various places such as homes, businesses, and industries. To meet the lighting needs in different scenarios, users usually need to adjust the beam angle of the lamps to change the range and direction of the light.

[0003] Currently, some angle-adjustable lighting fixtures exist on the market, typically employing a single pivot or ball joint structure to adjust the angle between the lamp body and the mounting surface. However, such structures have certain limitations in practical use. Specifically, when using a single pivot for adjustment, the lamp can often only rotate within a single plane, resulting in a limited adjustment dimension and making it difficult to achieve multi-directional, blind-angle-free illumination within a spatial range. While a simple ball joint structure can achieve omnidirectional adjustment, it often struggles to balance adjustment precision and post-adjustment positioning stability. After prolonged use or exposure to slight vibrations, the lamp body is prone to positional shifts, failing to stably maintain the desired illumination angle.

[0004] It is evident that existing lighting fixtures still fall short in terms of angle adjustment. Users cannot flexibly, accurately, and stably adjust the fixtures to the ideal illumination angle according to their actual needs, which to some extent affects the effective illumination range and lighting effect, failing to fully meet diverse usage scenarios. Therefore, the structure of existing lighting fixtures needs further improvement. Summary of the Invention

[0028] Reference Figures 1 to 6 An adjustable lamp structure includes a fixing element 10 and a lamp body 40. A first adjusting component 20 is rotatably connected to the fixing element 10, and a universal component 30 is rotatably connected to the first adjusting component 20. The lamp body 40 is fixedly mounted on the universal component 30.

[0029] The universal assembly 30 includes a universal ball head 310, a clamping sleeve 330, and a locking nut 340; the universal ball head 310 is fixedly connected to the lamp body 40; the clamping sleeve 330 is fixed to the rotating end of the first adjusting assembly 20; the universal ball head 310 is embedded in the clamping sleeve 330.

[0030] The clamping sleeve 330 includes a sleeve 331 fixedly connected to the first adjusting component 20 and a plurality of clamping pieces 332 spaced circumferentially on the sleeve 331, the clamping pieces 332 extending upward from the sleeve 331; the locking nut 340 is threadedly connected to the clamping sleeve 330 and its inner wall is provided with a pressing part 341 for pressing the clamping pieces 332 to deform inward.

[0031] When adjusting the angle of this lamp, the first adjustment component 20 is operated first to rotate relative to the fixed component 10, thereby driving the entire universal component 30 and the lamp body 40 to make a wide range of angle adjustments, so as to achieve the initial positioning of the illumination direction.

[0032] Then, fine adjustments are made: loosen the locking nut 340 to restore the clamping plate 332 to a relaxed state, at which point the universal ball head 310 can rotate freely within the clamping sleeve 330. The user can then move the lamp body 40, along with the universal ball head 310, to the desired illumination angle. Because the universal ball head 310 and the clamping sleeve 330 have a spherical fit, the lamp body 40 can flexibly deflect in any direction, achieving precise multi-angle illumination.

[0033] After adjustment, tighten the locking nut 340. During tightening, the squeezing part 341 on the inner wall of the locking nut 340 gradually compresses the multiple clamping pieces 332, causing them to contract evenly inward. This tightly grips the spherical surface of the universal ball joint 310, securing the universal ball joint 310 firmly through friction. At this point, the position of the lamp body 40 is stably fixed, completing all adjustment operations.

[0034] In this invention, the fixing element 10 has two upwardly extending connecting seats 50 spaced apart; the first adjusting assembly 20 includes a rotating seat 210, a damping bolt 220, and a damping nut 230; the rotating seat 210 is disposed between the two connecting seats 50, and the rotating seat 210 and the two connecting seats 50 are respectively provided with interconnected through holes; the damping bolt 220 passes through all the through holes and is threadedly connected to the damping nut 230, and the rotating seat 210 and the two connecting seats 50 are clamped between the damping nut 230 and the bolt head 221 of the damping bolt 220. This structure clamps the rotating seat between the two connecting seats through the damping bolt and the damping nut, forming a stable hinged connection. Its function is twofold: firstly, it enables a rotatable connection between the rotating seat and the fixed element, allowing the first adjustment component to be angled around the bolt axis; secondly, by adjusting the locking force of the damping bolt and the damping nut, it can control the frictional damping during rotation, so that the rotating seat can maintain its position by relying on friction after adjustment, ensuring that the lamp body will not rotate freely without external force, thus combining adjustment flexibility with positioning stability.

[0035] In this invention, a toothed disc 240 is provided on the end face of the rotating seat 210 that mates with the connecting seat 50. Its main function is to significantly increase the coefficient of friction between the rotating seat and the connecting seat through the convex and concave teeth on the toothed disc. When the damping bolt is tightened, the toothed disc presses against the end face of the connecting seat, providing greater frictional resistance, thereby improving the positioning stability of the rotating seat after adjustment and effectively preventing it from rotating or shifting when subjected to external forces or vibrations.

[0036] In this invention, the bottom surface 100 of the fixing element 10 is a fixed plane, and the rotation axis of the rotating seat 210 is parallel to the bottom surface 100. This design ensures that the rotation direction of the first adjustment component remains parallel to the mounting plane. When the lamp is installed on a wall or ceiling, the lamp body can be tilted or swung around an axis parallel to the mounting plane, ensuring that the adjustment action conforms to intuitive operating habits. It also facilitates coordination with adjustments in other directions, achieving more flexible control of the illumination angle.

[0037] In this invention, the clamping piece 332 gradually bends inward from bottom to top. Specifically, the clamping piece 332 bends upward into an arc shape to better fit with the universal ball joint 310. The clamping piece gradually bends inward from bottom to top into an arc shape so that its inner wall contour matches the spherical shape of the universal ball joint. Its function is to: increase the contact area between the clamping piece and the universal ball joint, making the clamping force distribution more uniform during locking, thereby improving the gripping effect and positioning stability of the ball joint; at the same time, the arc surface fit can reduce the local pressure on the surface of the ball joint, avoid damage to the ball joint during locking, and ensure that the adjustment process is smooth and without jamming.

[0038] In this invention, the clamping sleeve 330 is provided with a fitting and limiting part 350 for fitting against the lower surface of the universal ball joint 310. The fitting and limiting part within the clamping sleeve fits against the lower surface of the universal ball joint for two purposes: firstly, it provides stable bottom support for the universal ball joint, limiting its excessive embedding into the sleeve and ensuring the ball joint is always in the optimal clamping position; secondly, when the locking nut is not yet tightened, this limiting part prevents the ball joint from undergoing unexpected displacement due to gravity or external forces, allowing the user to maintain the ball joint's posture before adjustment, thus improving operational convenience and positioning accuracy.

[0039] In this invention, the fixing element 10 is a suction cup, which enables tool-free quick installation and removal, facilitating the temporary or flexible fixing of the lamp to smooth surfaces such as walls and tabletops, without leaving any installation marks after removal. This structure is particularly suitable for usage scenarios that require frequent changes in installation location or where drilling is not necessary, improving the convenience and flexibility of lamp use.

[0040] In this utility model, the universal ball joint 310 and the lamp body 40 are connected by a connecting post 320.

[0041] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
