Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a high-efficiency elephant trunk spotlight suitable for various scenarios. Background Technology

[0002] Elephant trunk spotlights are named for their lamp heads, which can be bent and adjusted like an elephant's trunk.

[0003] Existing elephant trunk spotlights typically have rotation and angle adjustment functions, but once rotated, the rotation position cannot be fixed. When shaking occurs, the rotation position of the lamp tube will change, resulting in inaccurate illumination direction. At the same time, the lamp tube angle adjustment is fixed inside the sleeve by screws and nuts, and the position of the lamp tube after the angle adjustment is completed is fixed by the friction between the nut and the outside of the sleeve. This fixing method is not secure, and the angle of the lamp tube is prone to change.

[0004] Therefore, a high-efficiency elephant trunk spotlight suitable for various scenarios is proposed to solve the problems mentioned above. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 5 This embodiment provides a high-efficiency elephant trunk spotlight suitable for various scenarios, including a lamp tube 1 and a face ring 3 fixedly connected to one end of the lamp tube 1. A sleeve 2 is fitted on the outside of the lamp tube 1, and two arc-shaped sliding grooves 6 are fixedly connected to the outside of the sleeve 2. The sliding grooves are provided through the outside of the sleeve 2, and a sliding shaft 7 is provided inside the sliding grooves. One end of the sliding shaft 7 is fixedly connected to the outside of the lamp tube 1, and a cylindrical block 8 is fixedly connected to the other end of the sliding shaft. Two fixing plates are fixedly connected to the outside of the cylindrical block 8, and arc-shaped sliders 9 are fixedly connected to one side of each of the two fixing plates. A fixing ring 10 is fixedly connected to the outside of the sleeve 2. An annular groove is opened on the inside of the fixing ring 10, and two elastic buckles 11 are fixedly connected to one end of the fixing ring 10. Several heat dissipation fins 4 are provided through the outside of the lamp tube 1, and the several heat dissipation fins 4 are symmetrically distributed.

[0026] The lamp tube 1 is slidably connected to the sleeve 2, and two limiting blocks 5 are fixedly connected to the outside of the face ring 3. One of the limiting blocks 5 is slidably connected inside the annular groove, and the sliding shaft 7 is slidably connected to the groove.

[0027] The arc-shaped slider 9 is slidably connected inside the arc-shaped groove 6, and the two elastic buckles 11 are symmetrically distributed;

[0028] The width of the arc-shaped slide groove 6 inside is gradually changing, and the width of the arc-shaped slide groove 6 is smaller the closer it is to the fixing ring 10;

[0029] The heat dissipation of the lamp tube 1 through the heat sink 4 and the fixation of the nose-shaped spotlight by the elastic buckle 11 are both existing technologies, so they are not described in detail in this embodiment.

[0030] At this time, the position of the nose-mounted spotlight is fixed by the elastic buckle 11. By pulling the lamp tube 1, the angle of the lamp tube 1 can be adjusted. The adjustment position of the lamp tube 1 can be fixed by the cooperation of the arc-shaped slider 9 and the arc-shaped groove 6. When it is necessary to change the illumination direction of the lamp tube 1, the lamp tube 1 is rotated. At this time, the lamp tube 1 drives the sleeve 2 to rotate. The rotation position of the lamp tube 1 can be fixed by the limiting component to prevent the rotation position of the lamp tube 1 from deviating, which would lead to inaccurate rotation position and improve the accuracy of adjustment. When the lamp tube 1 is pulled, the sliding shaft 7 will slide inside the groove with the movement of the lamp tube 1. The groove will limit the position of the sliding shaft 7 to prevent the sliding shaft 7 from deviating axially during movement. The cylindrical block 8 fixed to one end of the sliding shaft 7 will move with the sliding shaft 7. Two arc-shaped sliders 9 are fixedly connected to the outside of the cylindrical block 8, and the arc-shaped sliders 9 are slidably connected to the arc-shaped groove 6. This achieves the effect of limiting the extension and retraction position of the lamp tube 1. The arc-shaped groove 6 has a gradually changing groove width, and the arc-shaped sliders 9 are made of soft rubber. When the arc-shaped sliders 9 slide inside the arc-shaped groove 6, as they gradually approach the fixing ring 10, the arc-shaped groove 6 will gradually tighten the position of the arc-shaped sliders 9. When the arc-shaped sliders 9 slide to the minimum groove width of the arc-shaped groove 6, the extension position of the lamp tube 1 is at its maximum. The arc-shaped groove 6 fixes the position of the arc-shaped sliders 9 by squeezing them, thus achieving the effect of fixing the extension and retraction position of the lamp tube 1. By sliding a limiting block 5 inside the annular groove, the problem of the face ring 3 falling off during the extension and retraction adjustment of the lamp tube 1 can be prevented, thus improving the stability of the structure.

[0031] A fixing mechanism is provided on one side of the fixing ring 10;

[0032] The fixing mechanism includes a cylindrical sleeve 12 for fixing, a positioning rod 13 for pushing, and a spring 14 for providing power;

[0033] The cylindrical sleeve 12 is movably disposed on the outside of the lamp tube 1, and the positioning rod 13 is slidably connected inside the cylindrical sleeve 12. The lower end of the positioning rod 13 is through the cylindrical sleeve 12, and the spring 14 is sleeved on the outside of the positioning rod 13.

[0034] A cylindrical sliding block 15 is fixedly connected to the upper end of the positioning rod 13. The cylindrical sliding block 15 is slidably connected inside the cylindrical sleeve 12. Two fixing blocks are fixedly connected to the outer side of the cylindrical sleeve 12, and a telescopic rod 17 is fixedly connected to the upper end of each of the two fixing blocks.

[0035] Two telescopic rods 17 are fixedly connected to the upper ends of a connecting plate 18, and an L-shaped plate 16 is fixedly connected to the lower end of the connecting plate 18. One end of the L-shaped plate 16 is fixedly connected to the cylindrical sliding block 15, and the other end of the L-shaped plate 16 is fixedly connected to the outside of the sleeve 2.

[0036] In this process, the cylindrical sleeve 12 is manually pushed upwards, causing the spring 14, which is fitted around the positioning rod 13, to contract due to the pressure of the cylindrical sleeve 12. This allows the lamp tube 1 to rotate, thus adjusting its illumination direction. When the rotation is complete, the cylindrical sleeve 12 is released, and the spring 14 pushes it downwards due to its elasticity. At this point, the cylindrical sleeve 12 fits against the outside of the lamp tube 1, fixing its rotational position and preventing inaccurate illumination direction adjustment due to shaking after rotation. This improves the accuracy of the adjustment. The telescopic rod 17 is fixed to the outside of the cylindrical sleeve 12 by two fixing blocks to prevent jamming when the cylindrical sleeve 12 is manually pushed, thus improving the stability of the structure. The L-shaped plate 16 also helps to fix the position of the cylindrical sleeve 12.

[0037] The working principle of the above embodiments is as follows:

[0038] In use, the position of the nose-shaped spotlight is fixed by the elastic buckle 11. The angle of the lamp tube 1 can be adjusted by pulling it. The arc-shaped slider 9 can be fixed by squeezing the arc-shaped groove 6. The cylindrical sleeve 12 is pulled upward by hand. At this time, the face ring 3 is rotated. The sleeve 2 and the lamp tube 1 will rotate with the face ring 3 to adjust the illumination direction of the lamp tube 1. After the rotation adjustment is completed, the cylindrical sleeve 12 is released. The cylindrical sleeve 12 will push the lamp tube 1 downward to fix the rotation position of the lamp tube 1.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
