Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a multi-directional rotating lighting lamp. Background Technology

[0002] Currently, the mainstream multi-directional rotating lights on the market mainly fall into two categories in terms of their angle adjustment structures, both of which have obvious technical limitations: One type uses a transmission linkage hinge adjustment structure, which can achieve angle adjustment, but has a double contradiction and functional limitations: To avoid adjustment jamming, a certain gap needs to be reserved at the linkage hinge, but if the gap is too large, it will cause obvious "looseness" during the adjustment process; if the gap is reduced to improve stability, the sliding friction between the metal parts will increase, causing uneven adjustment resistance and obvious jamming, especially in scenarios with frequent fine adjustments, making it difficult to accurately control angle changes; at the same time, due to the limitation of the linkage length and the hinge point position, its adjustment angle is relatively simple and cannot meet multi-dimensional lighting needs; Another type uses a mounting base + damping ball adjustment structure. Although it is more flexible in adjustment than the linkage type, it lacks stability in long-term use. The surface of the damping ball is mostly made of rubber or soft plastic. During repeated rotation and compression, the surface is prone to scratches and deformation, which reduces the contact area with the inner wall of the mounting base and significantly reduces friction. After long-term use, the problem of "unable to fix the angle" often occurs. For example, spotlights will automatically return to their original position after adjustment, and wall-mounted lights cannot maintain their tilt due to insufficient damping force, which seriously affects the user experience. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this invention is to propose a multi-directional rotating lighting lamp that can be used for extended periods while still allowing for angle locking and smooth adjustment.

[0004] To achieve this objective, the present invention adopts the following technical solution: A multi-directional rotating lighting fixture includes a lamp holder and an LED light-emitting element. The lamp holder has a mounting groove, and the inner wall of the mounting groove has multiple guide grooves. Each guide groove has multiple positioning holes. The outer wall of the LED light-emitting element has the same number of mounting holes as the guide grooves. Each mounting hole has a limiting member that matches the positioning hole. The limiting member includes a return spring, a mounting base, and a ball bearing. The return spring is installed inside the mounting hole, and the mounting base is connected to the return spring. The mounting base has a recessed portion, and the ball bearing is rotatably fitted into the recessed portion. The ball bearing can engage with the positioning hole.

[0005] Preferably, in the above-mentioned multi-directional rotating lighting lamp, the inner wall of the mounting hole is provided with a limiting guide rail, the outer wall of the mounting base is provided with a limiting block, and the mounting base is slidably connected to the limiting guide rail through the limiting block.

[0006] Preferably, in the above multi-directional rotating lighting lamp, the mounting seat is provided with a latch portion facilitating connection with the return spring.

[0007] Preferably, in the above multi-directional rotating lighting lamp, positioning pins are oppositely disposed on an inner wall of the recessed portion, two ends of the ball are provided with connecting holes corresponding to the positioning pins, and the ball is rotatably connected to the positioning pins through the connecting holes.

[0008] Preferably, in the above multi-directional rotating lighting lamp, a plurality of the positioning holes are arranged sequentially along the guide groove.

[0009] Preferably, in the above multi-directional rotating lighting lamp, a plurality of the guide grooves are arranged on an inner wall of the mounting groove, and after each of the guide grooves is arranged sequentially, they are enclosed to form a "rice-shaped" adjustment opening.

[0010] Beneficial effects of the present utility model: (1) A plurality of guide grooves on an inner wall of the mounting groove form a multi-dimensional adjustment path, which makes adjustment smoother, and by matching with an equal number of limiting members on an outer wall of an LED light-emitting member, 360° rotation and multi-angle tilt adjustment can be achieved. Compared with the limitation of "unidirectional adjustment" of the traditional connecting rod hinged type, it can meet more complex lighting requirements. For example, a desktop table lamp can兼顾 both direct writing light and side fill light for a screen, and a commercial spotlight can flexibly adapt to lighting effects of exhibits at different angles.

[0011] (2) The limiting member comprises a return spring, a mounting seat and a ball. The return spring is built in the mounting hole. Under the reaction force of the return spring, an outward tightening force is always applied to the mounting seat, so that the ball continuously adheres to an inner wall of the positioning hole, which not only avoids the problem that the traditional damping ball "is easy to loosen without external force tightening", and ensures that the angle is not easy to shift after being fixed. On the one hand, the mounting seat is directly connected with the return spring, which provides a stable force-bearing support point for the spring and avoids offset and distortion of the spring during long-term compression-rebound processes; on the other hand, through the design of the recessed portion, the ball is rotatably embedded therein, which restricts the axial displacement of the ball and prevents it from falling off.

[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] like Figures 1-8As shown, a multi-directional rotating lighting lamp includes a lamp holder 11 and an LED light-emitting element 12. The lamp holder 11 is provided with a mounting groove 13, and the inner wall of the mounting groove 13 is provided with multiple guide grooves 14. Each guide groove 14 has multiple positioning holes 15. The outer wall of the LED light-emitting element 12 has the same number of mounting holes 16 as the guide grooves 14. The mounting holes 16 are provided with limiting members 17 adapted to the positioning holes 15. The limiting member 17 includes a return spring 18, a mounting base 19, and a ball bearing 20. The return spring 18 is installed inside the mounting hole 16, and the mounting base 19 is connected to the return spring 18. The mounting base 19 is provided with a recess 21, and the ball bearing 20 is rotatably embedded in the recess 21. The ball bearing 20 can engage with the positioning holes 15. The multiple guide grooves 14 on the inner wall of the mounting groove 13 form a multi-dimensional adjustment path, making it smoother during adjustment. In conjunction with the same number of limiting members 17 on the outer wall of the LED light-emitting element, a 360° rotation can be achieved. Rotation and multi-angle tilt adjustment, compared to the limitations of the transmission linkage hinge-type "single-direction adjustment", can meet more complex lighting needs. For example, desktop lamps can simultaneously provide direct writing light and side supplement light for screens, while commercial spotlights can flexibly adapt to different angles of lighting effects for exhibits.

[0017] It is worth noting that the multiple positioning holes 15 opened in each guide groove 14 provide clear locking nodes for angle adjustment. Users can insert the ball bearing 20 into the corresponding positioning hole 15 as needed to achieve step-like angle fixation, avoiding the problem of ambiguous angle positioning in traditional damping ball structures.

[0018] In this embodiment of the multi-directional rotating lighting lamp, the limiting component 17 includes a return spring 18, a mounting base 19, and a ball bearing 20. The return spring 18 is built into the interior of the mounting hole 16. Under the reaction force of the return spring 18, it always applies an outward pressing force to the mounting base 19, so that the ball bearing 20 continuously fits against the inner wall of the positioning hole 15. This avoids the problem of traditional damping balls being "easy to loosen without external force to tighten" and ensures that they are not easily displaced after the angle is fixed. Furthermore, the mounting base 19 is directly connected to the return spring 18, providing a stable force support point for the spring and preventing the spring from shifting or twisting during long-term compression-rebound. On the other hand, the design of the recessed part 21 allows the ball bearing 20 to be rotatably embedded in it, which restricts the axial displacement of the ball bearing 20 and prevents it from falling out.

[0019] In the multi-directional rotating illuminating lamp of this embodiment, the inner wall of the mounting hole 16 is provided with a limit guide rail 22, the outer wall of the mounting base 19 is provided with a limit block 23, and the mounting base 19 is in sliding fit connection with the limit guide rail 22 through the limit block 23; through the cooperation between the limit guide rail 22 and the limit block 23, the mounting base 19 can only perform reciprocating sliding along the axial direction of the mounting hole 16, that is, move linearly along with the compression / rebound of the return spring 18, which completely avoids the problem of radial deviation or rotational dislocation of the mounting base 19 caused by uneven spring force, force deviation of the balls 20 and other problems during long-term use.

[0020] In the multi-directional rotating illuminating lamp in some embodiments, the mounting base 19 is provided with a plug pin portion 24 that facilitates connection with the return spring 18; this allows the return spring 18 to be directly sleeved on the outer wall of the plug pin portion 24, which facilitates subsequent disassembly and installation, and prevents the return spring 18 from falling off.

[0021] In the multi-directional rotating illuminating lamp of this embodiment, positioning pins 25 are oppositely arranged on the inner wall of the recessed portion 21, both ends of the ball 20 are provided with connecting holes corresponding to the positioning pins 25, and the ball 20 is rotatably connected with the positioning pins 25 through the connecting holes; this achieves the dual effects of axial fixing and radial rotation of the ball 20. Through the cooperation of the positioning pins 25 and the connecting holes, the ball 20 is accurately limited in the axial direction within the recessed portion 21. The positioning pins 25 pass through the connecting holes at both ends of the ball 20 to form a pin constraint, which completely eliminates the risk of axial displacement and falling off of the traditional simply embedded ball 20 caused by long-term rolling, vibration or external impact.

[0022] In the multi-directional rotating illuminating lamp of this embodiment, a plurality of positioning holes 15 are arranged in sequence along the guide grooves 14; wherein a plurality of guide grooves 14 are arranged on the inner wall of the mounting groove 13, and after each guide groove 14 is arranged in sequence, they enclose to form a "rice-shaped" adjustment opening; the plurality of positioning holes 15 are completely arranged along the guide grooves 14, so that the lamp can achieve full-stroke angle coverage along the track of the guide grooves 14, and the guide grooves 14 are arranged in a "rice-shaped" shape. The positioning holes 15 on each guide groove 14 can cover an adjustment range of 0°-90°, and cooperating with the coordination of multiple guide grooves 14, it finally realizes 360° rotation + multi-angle tilt dead-angle-free adjustment. Such a design can be applied to more scenarios, thereby improving practicability.

[0023] The technical principle of the present utility model has been described above with reference to specific embodiments. These descriptions are only for explaining the principle of the present utility model, and cannot be construed as limiting the protection scope of the present utility model in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present utility model without creative labor, and these embodiments will all fall within the protection scope of the present utility model.
