Description

Technical Field

[0001] This utility model relates to the field of display cabinet technology, and in particular to an arc-top wiring structure for a display cabinet. Background Technology

[0002] To enhance display effects and visual appeal, some display cases adopt an arched dome design, displaying exhibits inside. Simultaneously, light strips installed inside the dome illuminate the exhibits, showcasing their structure more clearly and three-dimensionally, thus increasing their attractiveness. However, currently, the power supply wires connecting the light strips are typically fixed to the inner wall of the dome solely with adhesive. This method has significant drawbacks. Firstly, over long-term use, the adhesive gradually ages due to environmental factors, leading to a decrease in adhesion. Secondly, if the adhesive is applied unevenly or insufficiently during manufacturing, the wires may not bond firmly to the inner wall of the dome. Both of these situations can cause the light strips to detach from the inner wall of the dome and sag, not only ruining the overall aesthetics of the display case but also obscuring the exhibits, severely impacting their display effect.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an arc-top wiring structure for a display cabinet, which aims to hide the wiring and prevent the wires from hanging down and obstructing the exhibits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A curved top wiring structure for a display case includes an upwardly arched, arc-shaped front decorative strip, a back panel located behind the front decorative strip, multiple support beams for connecting the front decorative strip and the back panel, and an arc-shaped enclosure panel located between the front decorative strip and the back panel. A light groove is formed on the back of the front decorative strip, and a light strip is installed within the light groove. A wiring groove extending from front to back is formed on the upper surface of one of the support beams adjacent to the light groove, and a first wiring hole connecting the wiring groove and the light groove is formed at its end near the front decorative strip. A second wiring hole is formed on the back panel. One end of a power supply wire is electrically connected to the light strip, then passes through the first wiring hole and is embedded in the wiring groove, finally exiting from the second wiring hole. The front decorative strip, enclosure panel, and back panel form a display placement cavity.

[0007] As a further improvement to the above technical solution, the back of the front decorative strip is provided with a first arc-shaped groove extending to both ends thereon, and the front end surface of the back panel is provided with a second arc-shaped groove corresponding to the first arc-shaped groove. The first arc-shaped groove and the second arc-shaped groove are located on the outside of the support beam, and the front and rear edges of the enclosure are respectively embedded in the first arc-shaped groove and the second arc-shaped groove.

[0008] As a further improvement to the above technical solution, the lamp trough has an arc-shaped structure, the lamp strip is provided with a female terminal, and the power supply wire is provided with a male terminal that mates with the female terminal.

[0009] As a further improvement to the above technical solution, the back of the front decorative strip is provided with a plurality of first threaded holes, each first threaded hole being fitted with a first mating screw, and the support beam is provided with a first insertion hole for inserting the first mating screw and a first locking hole for installing a first locking element to hold the first mating screw.

[0010] As a further improvement to the above technical solution, the front end face of the back plate is provided with a plurality of second threaded holes, each second threaded hole is provided with a second mating screw, and the support beam is provided with a second insertion hole for inserting the second mating screw and a second locking hole for installing a second locking member to lock the second mating screw.

[0011] As a further improvement to the above technical solution, the arc-top wiring structure also includes a layer plate. The upper surface of the layer plate is provided with a plurality of third threaded holes, and a third mating screw is installed in each third threaded hole. The supports near the two ends of the front decorative panel are vertically oriented toward the layer plate. The support beam is provided with a third insertion hole for the third mating screw to be inserted and a third locking hole for installing a third locking element to lock the third mating screw.

[0012] As a further improvement to the above technical solution, the layer plate is provided with straight grooves for the left and right edges of the enclosure to be inserted.

[0013] As a further improvement to the above technical solution, the back of the back plate is provided with a wire clamp for guiding the power supply wires.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, the arc-shaped wiring structure provided by this utility model uses wiring grooves on the support beam, a first wiring hole, and a second wiring hole on the back plate to embed the power supply wires into the wiring grooves for wiring and fixation. In other words, the power supply wires are supported and hidden by the support beam. This physical limiting and fixing method eliminates the need for glue, thereby fundamentally avoiding problems such as glue aging and uneven application that could cause the wires to fall off.

Detailed Implementation

[0025] This utility model provides a curved top wiring structure for a display cabinet. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] Please see Figures 1 to 9This utility model provides an arc-shaped wiring structure for a display cabinet, including an upwardly arched and arc-shaped front decorative strip 1, a back panel 2 located behind the front decorative strip 1, multiple support beams 3 for connecting the front decorative strip 1 and the back panel 2, and an arc-shaped enclosure 4 located between the front decorative strip 1 and the back panel 2; a light groove 11 is provided on the back of the front decorative strip 1, and a light strip 5 is provided in the light groove 11. A wiring groove 31 extending from front to back is provided on the upper surface of a support beam 3 adjacent to the light groove 11, and a first wiring hole 32 connecting the wiring groove 31 and the light groove 11 is provided at its end near the front decorative strip 1. A second wiring hole 21 is provided on the back panel 2. One end of a power supply wire 6 is electrically connected to the light strip 5, then passes through the first wiring hole 32 and is embedded in the wiring groove 31, and finally leads out from the second wiring hole 21; the front decorative strip 1, the enclosure 4, and the back panel 2 form a display placement cavity 10.

[0027] In the arc-shaped ceiling wiring structure of this display case, the front decorative strip 1, back panel 2, support beam 3, and surrounding panel 4 together constitute the main arc-shaped ceiling structure of the display case. The exhibit placement cavity 10 formed by the front decorative strip 1, surrounding panel 4, and back panel 2 is used to display exhibits. The light trough 11 of the front decorative strip 1 is used to install light strips 5. The light emitted by the light strips 5 can illuminate the exhibits to enhance the display effect. One end of the power supply wire 6 is electrically connected to the light strip 5 in the light trough 11 to provide power to the light strip 5. Subsequently, the power supply wire 6 passes through the first wiring hole 32 on the upper surface of the support beam 3 adjacent to the light trough 11 and enters the wiring trough 31. The wiring trough 31 serves to store and guide the power supply wire 6. Finally, the power supply wire 6 is led out from the second wiring hole 21 on the back panel 2 and connected to an external power source, thus forming a complete power supply circuit, enabling the light strip 5 to emit light normally and provide illumination for the exhibits.

[0028] Unlike traditional methods that rely solely on glue to fix the power supply wire 6, the arc-top wiring structure provided by this invention uses a wiring groove 31 on the support beam 3, a first wiring hole 32, and a second wiring hole 21 on the back plate 2 to embed the power supply wire 6 into the wiring groove 31 for routing and fixing. In other words, the power supply wire 6 is supported and hidden by the support beam 3. This physical limiting and fixing method eliminates the need for glue, thus fundamentally avoiding problems such as glue aging or uneven application that could cause the wire to fall off. This greatly improves the reliability of the wire fixing, effectively prevents the light strip 5 from sagging due to loose wires, and ensures the long-term stable use of the display cabinet.

[0029] Of course, please see Figure 5The wiring trough 31 can also be sealed with tape 92. The tape 92 completely covers and hides the wires inside the wiring trough 31, making the wiring inside the display case neater and more aesthetically pleasing. It prevents exposed wires from affecting the overall visual effect of the display case, further fixes the wire position, and prevents the wires from shaking or shifting within the wiring trough 31. This also prevents poor contact or wire detachment due to loose wires, ensuring stable power supply to the light strip 5.

[0030] For details, please refer to Figure 7 The back of the front decorative strip 1 is provided with a first arc-shaped groove 12 extending to both ends thereon, and the front surface of the back plate 2 is provided with a second arc-shaped groove 22 corresponding to the first arc-shaped groove 12. The first arc-shaped groove 12 and the second arc-shaped groove 22 are located on the outside of the support beam 3, and the front and rear edges of the enclosure plate 4 are respectively embedded in the first arc-shaped groove 12 and the second arc-shaped groove 22.

[0031] It should be noted that the enclosure panel 4 is actually a deformable flexible panel. The first arc-shaped groove 12 on the back of the front decorative strip 1 and the second arc-shaped groove 22 on the front surface of the back panel 2 provide a precise positioning structure for the installation of the enclosure panel 4. When assembling the arc top of the display cabinet, the enclosure panel 4 can be quickly installed simply by inserting the front and rear edges of the enclosure panel 4 into the corresponding grooves, without the need for complicated auxiliary tools and cumbersome operating steps. This greatly improves production and assembly efficiency and reduces labor costs and installation time.

[0032] In this embodiment, the light trough 11 has an arc-shaped structure, matching the arc-shaped design of the display cabinet's top, allowing the light strip 5 to fit snugly against the light trough 11 and fully adapt to the curved surface of the top. The light strip 5 is equipped with a female terminal 51, and the power supply wire 6 is equipped with a male terminal 62 that mates with the female terminal 51. This pluggable connection method of the male and female terminals not only provides reliable electrical connection performance but also greatly simplifies the installation process of the light strip 5 and the power supply wire 6. During installation, no complex tools or professional skills are required; simply inserting the male terminal 62 into the female terminal 51 completes the circuit connection. When inspecting or replacing the light strip 5, the connection can be quickly disconnected, facilitating operation. This design significantly improves installation efficiency, reduces maintenance difficulty, and minimizes repair time and costs caused by circuit connection problems.

[0033] For details, please refer to Figure 3 and Figure 4The back of the front decorative strip 1 has multiple first threaded holes 13, and each first threaded hole 13 is fitted with a first mating screw 71. The support beam 3 has a first insertion hole 33 for inserting the first mating screw 71 and a first locking hole 34 for installing a first locking member 74 to hold the first mating screw 71 in place. This installation method not only facilitates installation but also effectively resists external impacts and vibrations during the use of the display cabinet, preventing loosening or displacement between the front decorative strip 1 and the support beam 3, ensuring the overall stability of the arched top structure of the display cabinet, and providing reliable structural support for the wiring of the light strip 5 and the display of exhibits.

[0034] Similarly, for the sake of standardizing the installation method, please refer to [link / reference]. Figure 6 The front end face of the back plate 2 has multiple second threaded holes 23, each with a second mating screw 72 installed. The support beam 3 has a second insertion hole 35 for inserting the second mating screw 72 and a second locking hole 36 for installing a second locking element 75 to hold the second mating screw 72 in place. This multi-fixing method can effectively resist external forces such as collisions and vibrations during daily use of the display case, prevent the back plate 2 and the support beam 3 from loosening or shifting, greatly enhance the stability of the overall arched structure of the display case, and provide reliable support for the display of exhibits and the internal wiring structure.

[0035] Please see Figure 8 and Figure 9 This technical solution also includes a shelf 8 located below the arched top structure. After the arched top structure is assembled, it is installed on the shelf 8. The upper surface of the shelf 8 has multiple third threaded holes 81, and each third threaded hole 81 is fitted with a third mating screw 73. The supports near both ends of the front decorative panel face vertically toward the shelf 8. The support beam 3 has third insertion holes 37 for inserting the third mating screw 73 and third locking holes 38 for installing third locking parts 76 to hold the third mating screw 73 in place. During installation, the user can quickly and accurately insert the third mating screw 73 into the corresponding hole, reducing adjustment steps during installation and lowering the assembly difficulty.

[0036] The supports near both ends of the front decorative panel press against the shelf 8 to form a symmetrical mechanical support structure. This layout can evenly distribute the weight of the arched structure and external pressure to the shelves and the overall frame of the display case, avoiding local stress concentration caused by the offset of the support points.

[0037] For further details, please refer to Figure 8 and Figure 9The shelf 8 has straight grooves 82 for the left and right edges of the enclosure 4 to be inserted. After the left and right edges of the enclosure 4 are inserted into the straight grooves 82, they form a tight fit with the shelf 8, restricting the displacement and swaying of the enclosure 4 in the left and right directions, and enhancing the stability of the enclosure 4 installation. Combined with the connection structure of the front decorative strip 1, the back panel 2 and the support beam 3, the display case forms a stable three-dimensional frame, effectively resisting the influence of external collisions, handling vibrations and other external forces, avoiding overall structural deformation caused by loose enclosure 4, providing reliable structural protection for the display of exhibits, and extending the service life of the display case.

[0038] In addition, the tight fit between the straight groove 82 and the enclosure 4 effectively prevents light from leaking out from the gap between the enclosure 4 and the shelf 8, ensuring that the light emitted by the light strip 5 is concentrated on the exhibits, avoiding stray light caused by light leakage, which would affect the display effect of the exhibits and the visual experience of the audience.

[0039] For preferred options, please refer to [link / reference]. Figure 2 The back of the back panel 2 is provided with a wire clamp 91 for guiding the power supply wire 6. The wire clamp 91 can guide and organize the power supply wire 6 in an orderly manner, making the wire routing on the back of the back panel 2 more neat and standardized, avoiding messy tangling of the wire, and better connecting with other power supply wires 6 on the display cabinet.

[0040] The first mating screw 71, the second mating screw 72, and the third mating screw 73 are specifically two-in-one quick-connect rods, and the first locking member 74, the second locking member 75, and the third locking member 76 are specifically eccentric wheel fasteners.
