Description

Technical Field

[0001] The utility model belongs to the technical field of display cabinet lighting, and particularly relates to a lighting structure. Background Art

[0002] In the field of display cabinets, existing display cabinet lighting mostly provides light strips on the top plate or the edge of the top plate, and provides lighting through the light emission of multiple lamp beads.

[0003] However, some special display cases have very demanding lighting requirements. For example, in jewelry display cases, different jewelry has different shapes and properties. This single top-mounted lighting method cannot meet the jewelry's specific lighting needs. If the lighting angle needs to be adjusted, it usually requires opening the cabinet, which is extremely inconvenient.

[0004] Based on this, a new lighting structure for display cabinets is proposed. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a lighting structure that can adjust the distance and angle of the lighting fixture to meet different exhibit display requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0022] Please refer to Figure 1-Figure 5 As shown, a lighting structure includes a base 1, a display stand 2 is set in the center of the upper surface of the base 1, a transparent glass window 3 is fixed to the outer side of the top of the base 1, the display stand 2 is placed between the four transparent glass windows 3, and a top cover 4 is fixed on the top of the four transparent glass windows 3. The four transparent glass windows 3 and the top cover 4 form a sealed space to effectively protect the exhibits. The top cover 4 is placed directly above the display stand 2. A main lighting lamp 6 is installed in the center of the lower surface of the top cover 4, so that light is emitted from top to bottom to provide main lighting. The lower surface of the top cover 4 is symmetrically provided with mounting grooves 5, and the two mounting grooves 5 are placed On both sides of the main lighting lamp 6, a track rod 8 is installed inside the mounting groove 5 through a bearing, and a convex strip 81 is provided on the surface of the track rod 8. A sliding sleeve 9 is slidably installed on the surface of the track rod 8. The inner wall of the sliding sleeve 9 is provided with a groove adapted to the convex strip 81, so that the sliding sleeve 9 can only move along the axis of the track rod 8 and cannot rotate relative to it. However, when the track rod 8 rotates, the sliding sleeve 9 can be driven to rotate. An adjustment lamp tube 20 is provided at the bottom of the sliding sleeve 9, and the adjustment lamp tube 20 is tilted, so that multiple adjustment lamp tubes 20 are respectively provided on both sides of the main lighting lamp 6 to provide lighting for the side of the exhibits.

[0023] Please refer to Figure 3 and Figure 5 As shown, a gear 10 is provided at the front end of the track rod 8, and a double-threaded rod 13 is horizontally installed on the front side of the inner part of the top cover 4 through a bearing. The double-threaded rod 13 is arranged perpendicular to the track rod 8, and the height of the double-threaded rod 13 is slightly lower than the track rod 8. Adjustment blocks 12 are symmetrically screwed on the surface of the double-threaded rod 13, and the two adjustment blocks 12 are screwed on different thread surfaces respectively. When the double-threaded rod 13 rotates, the two adjustment blocks 12 can be driven to move synchronously, approaching or moving away synchronously. A tooth plate 11 is provided on the top of the adjustment block 12, and the tooth plate 11 is placed below the gear 10, and the tooth plate 11 and the gear 10 are engaged with each other to control the angle of the adjustment lamp tube 20. When the two tooth plates 11 move away from each other, the adjustment lamp tube 20 can be driven to increase the illumination angle and shift the lighting point downward to adapt to the lighting of smaller exhibits.

[0024] Please refer to Figure 1 and Figure 5As shown, one end of the double-threaded rod 13 passes through the side surface of the top cover 4, and a knob A14 is provided at the end of the double-threaded rod 13. The knob A14 is placed on the outside of the top cover 4 to facilitate control of the double-threaded rod 13 from the outside and adjustment of the interior without opening the display case.

[0025] Please refer to Figures 1-4 As shown, a fan-shaped plate 91 is provided on the side of the sliding sleeve 9 away from the adjustment lamp tube 20 , and the center of the fan-shaped plate 91 coincides with the axis of the track rod 8 . When the adjustment lamp tube 20 rotates, the fan-shaped plate 91 also rotates, but is always placed between the two clamping rods 16 .

[0026] Among them, the upper surface of the top cover 4 is symmetrically provided with a slide groove 7, the cross-section of the slide groove 7 is step-shaped, the slide groove 7 is connected with the installation groove 5, the slide groove 7 is parallel to the axis of the track rod 8, and a moving block 15 is slidably installed at the bottom of the slide groove 7. The moving block 15 has a T-shaped structure to contact the inner wall of the stepped slide groove 7. The clamping rod 16 is symmetrically arranged at the bottom of the moving block 15, and the fan-shaped plate 91 is placed between the two clamping rods 16. The moving block 15 can only move along the track of the slide groove 7, so it can drive the sliding sleeve 9 to move along the axis of the track rod 8 to adjust the distance of multiple adjustment lamp tubes 20.

[0027] Please refer to Figure 4 As shown, a locking bolt 18 is provided on the top of the moving block 15, and the locking bolt 18 passes through the upper surface of the base 1. A pressure block 17 is screwed on the top of the locking bolt 18, and the pressure block 17 is placed above the top cover 4. A knob B19 is provided on the top of the pressure block 17. Screwing the locking bolt 18 can make the pressure block 17 and the moving block 15 close to each other, and then keep them fixed by squeezing with the surface of the top cover 4.

[0028] The working principle of the present invention is as follows: the exhibits are placed on the display stand 2, and the transparent glass windows 3 on the four sides and the top cover 4 are used to maintain a sealed space inside to effectively protect the exhibits. The position of the lamp tube 20 can be adjusted according to the usage. At this time, the pressure block 17 can be released, and the knob B19 can be moved to drive the moving block 15 to move along the track of the slide 7. The two clamping rods 16 and the fan-shaped plate 91 cooperate to drive the sliding sleeve 9 to move along the axis of the track rod 8, thereby controlling the position of the lamp tube 20, and then the lock is screwed in. The pressing block 17 is used to pull the moving block 15 upward, and is kept fixed by squeezing the surface of the top cover 4, thereby maintaining the stability of the position of the adjustment lamp tube 20. The rotating knob A14 can drive the double-threaded rod 13 to rotate, and then control the two adjustment blocks 12 to move closer or farther away synchronously to adjust the position of the tooth plate 11. The track rod 8 is driven to rotate by the cooperation of the tooth plate 11 and the gear 10. Due to the presence of the convex strip 81, the angle of the lamp tube 20 can be controlled and adjusted during the rotation of the track rod 8 to adapt to different exhibit lighting operations.

[0029] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
