[0002] Through light refraction, making light pass through different media can create different light effects, achieving the effects of enhancing the color and texture of commodities, attracting customers' attention and stimulating the desire to purchase. We all know that the incident angle affects the size of the refraction angle, and when the incident light angle changes, the direction of the refracted light will change.

Specific embodiments

[0029] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0030] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meaning understood by those with ordinary skills in the field to which the present utility model belongs.

[0031] As Figure 1 shown, a light refraction angle adjustment structure of a light bar luminous display rack includes: a platform 1; the adjustment structure further includes: eight mutually connected light bars 9 in series; a rotating shaft 16 connected to each light bar 9; a turntable 5 rotatably arranged on the platform 1, the turntable 5 is provided with a rotating groove, and the other end of the rotating shaft 16 penetrates through the rotating groove and is connected with a gear 17; a rack 18 arranged on the platform 1, the rack 18 meshes with the gear 17; a driving component for driving the turntable 5 to rotate relative to the platform 1;

[0032] Adopting the above technical solution can adjust the incident angle of the light beam of the light bar 9, and further adjust the light refraction angle. When in use, start the driving component to drive the turntable 5 to rotate. The turntable 5 synchronously drives the rotating shaft 16 and the gear 17 to revolve. Since the rack 18 is relatively stationary, when the gear 17 meshes with the rack 18, the gear 17 will drive the rotating shaft 16 to rotate self - synchronously, and the rotating shaft 16 drives the light bar 9 connected thereto to rotate self - synchronously, thereby realizing the adjustment of the incident angle of the light beam of the light bar 9. There is no need to open the display cabinet for disassembly and reinstallation, and the efficiency is relatively high.

[0033] As Figure 3 shown, in this embodiment, the driving component is the motor 4 arranged at the bottom of the platform 1, and the output shaft of the motor 4 is connected to the turntable 5;

[0034] Adopting the above technical solution can drive the turntable 5 to rotate through the motor 4, and the motor 4 is preferably a servo motor.

[0035] As Figure 3 and Figure 4 shown, in this embodiment, an annular flange 6 is arranged on the inner wall of the platform 1, and the annular flange 6 is in rotational fit with the annular groove 7 opened on the side of the turntable 5;

[0036] Adopting the above technical solution can ensure the stable rotation of the turntable 5. Through the annular flange 6 and the annular groove 7, the turntable 5 can be stably supported, preventing the output shaft of the motor 4 from being damaged due to the shaking of the turntable 5.

[0037] As Figure 3 shown, in this embodiment, there are two turntables 5, and the two turntables 5 are symmetrically arranged up and down with respect to the light bar 9 to respectively connect the rotating shafts 16 located at the top and bottom of the light bar 9. A connecting rod is arranged between the two turntables 5;

[0038] Adopting the above technical solution can improve the connection stability of the light bar 9. The light bar 9 is preferably an LED light bar. By arranging two turntables 5, the upper and lower ends of the light bar 9 can be respectively connected and limited, improving the support stability of the light bar 9 and preventing the light bar 9 from tilting.

[0039] As Figure 3 and Figure 5 shown, in this embodiment, the adjustment structure further includes: a connecting plate 8 connected to the rotating shaft 16, and the connecting plate 8 is detachably connected to the light bar 9; specifically, an insertion block 10 is arranged at the rear end of the light bar 9, and the insertion block 10 is in snap - fit with the insertion slot 11 opened in the connecting plate 8; an inner slot 12 communicating with the insertion slot 11 is opened inside the connecting plate 8, a spring 13 is arranged in the inner slot 12, the spring 13 is connected with a stopper 14, and the stopper 14 is in snap - fit with the concave cavity 15 opened on the surface of the insertion block 10. The insertion block 10 and the stopper 14 are both provided with bevels for easy insertion or extraction;

[0040] Adopting the above technical solution can facilitate the disassembly of the light bar 9. When it is necessary to disassemble a certain light bar 9, turn off the power of the light bar 9, pull out the wiring of the terminal connected in series on this light bar 9, hold the side of the light bar 9 and apply force outward, so that the concave cavity 15 on the side of the plug block 10 disengages from the engagement with the stop block 14, and continue to apply force to pull the plug block 10 until it disengages from the slot 11 to complete the disassembly. As another alternative solution, the light bar 9 and the connecting plate 8 can also be fixed by a magnetic attraction method.

[0041] As Figure 1 and Figure 2 shown, in this embodiment, a refraction cover 19 for cooperating with the light bar 9 is arranged outside the platform 1; a positioning rod 20 is connected to the lower end of the refraction cover 19, and the positioning rod 20 is in plug-in fit with a positioning groove 21 opened on the surface of the platform 1;

[0042] Adopting the above technical solution can facilitate the disassembly of the refraction cover 19. During normal use, the light beam emitted by the light bar 9 irradiates the refraction cover 19 after passing through the air. Since the refraction cover 19 and the air are different propagation media, the light is refracted. The refraction cover 19 can be made of glass. In order to correspond to the eight light bars 9, the refraction cover 19 needs to be set in a regular octagon structure. When it is necessary to disassemble the refraction cover 19, just lift the refraction cover 19 so that the positioning rod 20 at its bottom disengages from the positioning groove 21, and the refraction cover 19 can be disassembled.

[0043] As Figure 1 and Figure 3 shown, in this embodiment, feet 2 are arranged at the bottom of the platform 1, and mounting holes 3 are opened in the feet 2;

[0044] Adopting the above technical solution can facilitate the fixing of this device in the display cabinet. By embedding bolts into the mounting holes 3 of the feet 2 and threadedly connecting with the display cabinet, the fixing can be completed.

[0045] Working principle: Start the motor 4 to drive the turntable 5 to rotate. The turntable 5 synchronously drives the rotation shaft 16 and the gear 17 to revolve. Since the rack 18 is relatively stationary, when the gear 17 meshes with the rack 18, the gear 17 will drive the rotation shaft 16 to rotate self, and the rotation shaft 16 drives the light bar 9 connected thereto to rotate self synchronously, thereby realizing the adjustment of the incident angle of the light beam of the light bar 9. The light beam emitted by the light bar 9 irradiates the refraction cover 19 after passing through the air. Since the refraction cover 19 and the air are different propagation media, the light is refracted;

[0046] When it is necessary to disassemble a certain light bar 9, turn off the power of the light bar 9, pull out the wiring of the terminal connected in series on this light bar 9, hold the side of the light bar 9 and apply force outward, so that the concave cavity 15 on the side of the plug block 10 disengages from the engagement with the stop block 14, and continue to apply force to pull the plug block 10 until it disengages from the slot 11 to complete the disassembly;

[0047] When it is necessary to disassemble the refraction cover 19, simply lift the refraction cover 19 so that the positioning rod 20 at its bottom disengages from the positioning groove 21, and then the refraction cover 19 can be disassembled.
