Description

Technical Field

[0001] The present invention relates to the technical field of decorative lamps, and in particular to a circular decorative lamp sign that can be spliced. Background Art

[0002] As people's living standards and aesthetic tastes continue to improve, lighting signs are becoming more versatile, not just for simple lighting but also for wall decoration. However, conventional sign-shaped lighting fixtures have a fixed, monotonous structure and lack flexibility. They cannot be combined to suit actual needs or preferences, making it difficult to display diverse patterns and content. Over time, these fixtures can create a monotonous visual effect and cause visual fatigue. Furthermore, their fixed, unchangeable shape occupies a large space, making them difficult to transport and package, resulting in high transportation and packaging costs. Therefore, designing a modular, circular lighting sign that offers increased design flexibility and facilitates storage and transportation has become a pressing technical challenge. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a circular lighting sign that can be spliced.

[0004] The technical solution of the present utility model is a splicable circular lighting sign, comprising a circular outer frame and a luminous light sign connected to the inner side of the outer frame, an annular groove is provided on the back side of the outer frame, the annular groove is concentric with the outer frame, the annular groove is provided with a plurality of fixing parts and a splicing plate, the fixing parts include a sliding block, a threaded rod and a positioning nut, the sliding block is clamped in the annular groove for sliding fit, the threaded rod is connected to the sliding block and extends out of the annular groove, the positioning nut is screwed with the part of the threaded rod extending out of the annular groove, and both ends of the splicing plate are provided with a clamping groove matching the size of the threaded rod.

[0005] After adopting the above structure, by arranging multiple circular light decorative boards adjacent to each other, the outer peripheral surface of the outer frame is fitted together, and the light-emitting light decorative boards on the inner side of the outer frame are arranged to form a series of graphic combinations, the threaded rod is pushed to make the sliding block move along the annular groove, and two fixing parts corresponding to the positions are formed on the adjacent light decorative boards. A splicing plate is taken, and the clamping grooves at both ends of the splicing plate are clamped on the threaded columns of the fixing parts with corresponding positions. The positioning nut is turned to move closer to the sliding block, and the splicing plate is pressed against the back of the outer frame to fix the position of the splicing plate, thereby forming a support between the adjacent light decorative boards and fixing the positions of the two. By adjusting the light decorative boards during the process of fixing the outer frame, the position of the splicing board is adjusted. The arrangement of the signs allows the lighting signs to be flexibly formed into different shapes, thereby changing the graphic combination, giving people a variety of visual effects and not easily causing visual fatigue; when it needs to be stored and transported, just reverse the positioning nut to loosen the splicing plate. After removing the splicing plate from the threaded column, the outer frame can be stacked coaxially more tightly, reducing the space occupied; the snap-in grooves at both ends of the splicing plate are respectively clamped on the threaded rods of adjacent lighting signs, and the positioning nuts are tightened to press the splicing plate against the back of the outer frame for positioning, which can more flexibly fix multiple lighting signs into different shapes, and can also be coaxially stacked for storage, reducing the space occupied during transportation.

[0006] As a further improvement of the present invention, raised limit blocks are provided on both sides of the slot of the snap-fit ​​slot, the spacing between the limit blocks of the same snap-fit ​​slot is smaller than the diameter of the threaded rod, and the edge of the snap-fit ​​slot is chamfered to form a rounded corner.

[0007] After adopting the above structure, by setting raised limit blocks on both sides of the slot of the clamping groove, when the threaded rod is retracted into the clamping groove, relying on the toughness of the clamping groove, the limit blocks are squeezed toward both sides of the slot of the clamping groove, so that the spacing between the limit blocks is increased to allow the threaded rod to enter, and then relying on the toughness of the clamping groove to push the limit blocks to reset, clamping the threaded rod in the clamping groove to prevent the threaded rod from falling out of the clamping groove.

[0008] As a further improvement of the present invention, the side surface of the clamping groove is provided with a reinforcing rib of matching shape, and the reinforcing rib extends to the side surface of the splicing plate.

[0009] After adopting the above structure, reinforcing ribs are set on the side of the clamping groove, and the reinforcing ribs extend to the side of the splicing plate, so as to prevent the clamping groove from breaking when it is clamped on the threaded rod, and to prevent the clamping groove from breaking from the splicing plate.

[0010] As a further improvement of the present invention, the side surfaces of the splicing plate are covered with an anti-slip pad layer.

[0011] With the above structure, the side of the splicing plate is covered with an anti-slip pad, which increases the friction generated when the splicing plate is pressed against the back of the outer frame, prevents the splicing plate from sliding on the outer frame, and improves the supporting strength.

[0012] As a further improvement of the present invention, the outer frame, the fixing parts and the splicing plates are all made of transparent materials.

The annular groove 3 is provided with a number of fixing parts and a splicing plate 4. The fixing parts include a sliding block 5, a threaded rod 6 and a positioning nut 7. The sliding block 5 is clamped in the annular groove 3 for sliding fit. The threaded rod 6 is connected to the sliding block 5 and extends out of the annular groove 3. The positioning nut 7 is screwed with the part of the threaded rod 6 that extends out of the annular groove 3. Both ends of the splicing plate 4 are provided with a clamping groove 8 that matches the size of the threaded rod 6.

[0018] By arranging multiple circular light decorative boards adjacent to each other so that the outer peripheral surface of the outer frame 1 fits together, the light-emitting light boards 2 on the inner side of the outer frame 1 are arranged to form a series of graphic combinations, and the threaded rod 6 is pushed to move the sliding block 5 along the annular groove 3 to form two corresponding fixing parts on the adjacent light decorative boards. A splicing plate 4 is taken, and the clamping grooves 8 at both ends of the splicing plate 4 are clamped on the threaded columns of the fixing parts with corresponding positions. The positioning nut 7 is turned to move closer to the sliding block 5, and the splicing plate 4 is pressed against the back of the outer frame 1 to fix the position of the splicing plate 4. A support is formed between the adjacent light decorative boards to fix the positions of the two. By adjusting the position of the light decorative board in the process of fixing the outer frame 1 The lines are arranged so that the lighting signs can be flexibly formed into different shapes, thereby changing the graphic combination, giving people a variety of visual effects and not easily causing visual fatigue; when it needs to be stored and transported, it is only necessary to reverse the positioning nut 7 to loosen the splicing plate 4. After the splicing plate 4 is removed from the threaded column, the outer frame 1 can be stacked coaxially more tightly, reducing the space occupied; the clamping grooves 8 at both ends of the splicing plate 4 are respectively clamped on the threaded rod 6 of the adjacent lighting sign, and the positioning nut 7 is tightened to press the splicing plate 4 on the back of the outer frame 1 for positioning, so that multiple lighting signs can be fixed into different shapes more flexibly, and can also be coaxially stacked for storage, reducing the space occupied during transportation.

[0019] Raised limit blocks 9 are provided on both sides of the slot opening of the snap-fit ​​slot 8 . The spacing between the limit blocks 9 of the same snap-fit ​​slot 8 is smaller than the diameter of the threaded rod 6 . The edges of the snap-fit ​​slot 8 are chamfered to form rounded corners.

[0020] By setting raised limit blocks 9 on both sides of the slot of the snap-fit ​​groove 8, when the threaded rod 6 is retracted into the snap-fit ​​groove 8, the limit blocks 9 are squeezed toward both sides of the slot of the snap-fit ​​groove 8 by relying on the toughness of the snap-fit ​​groove 8, so that the spacing between the limit blocks 9 is increased to allow the threaded rod 6 to enter, and then the limit blocks 9 are pushed back to their original position by relying on the toughness of the snap-fit ​​groove 8, clamping the threaded rod 6 in the snap-fit ​​groove 8 to prevent the threaded rod 6 from falling out of the snap-fit ​​groove 8.
