Description

Technical Field

[0001] This utility model relates to the field of display lighting accessories, and in particular to a modular shelf light with a snap-locking structure. Background Technology

[0002] Shelf lights (also known as LED shelf lights or rack lights) are specialized lighting devices for display cabinets, shelves, and other shelves. Their core value lies in enhancing the display effect of exhibited items through precise light distribution. This relies on a stable installation structure and reliable conductivity. Current mainstream technologies in the industry generally adopt modular plug-in designs to achieve rapid installation and flexible replacement. For example, the shelf light solution disclosed in Chinese utility model patent CN108916711A uses a plug-in electrical connection between the conductive contact piece at the end of the shelf and the conductive strip in the support track. Simultaneously, it utilizes the first locking part between the conductive contact piece and the insulating groove to achieve mechanical anti-detachment: the conductive contact piece relies on its own metal elastic deformation to lock into the pre-set structure of the insulating groove, completing current conduction while simultaneously fixing the shelf. However, this solution essentially represents a dual application of a single functional component; the same conductive contact piece must both conduct current and provide mechanical anti-detachment. Significant drawbacks remain in practical applications: First, as a metallic elastic component, the conductive contact piece must repeatedly withstand deformation stress during high-frequency insertion and removal operations. The inherent fatigue characteristics of metallic materials mean that its elasticity gradually diminishes with increasing usage. For example, in supermarket settings, shelf panels may undergo frequent disassembly and reassembly due to product display adjustments. After a period of time, a noticeable decrease in the elasticity of the contact piece can be observed, causing the connection between the shelf and the support to become loose, even resulting in wobbling upon slight contact. This phenomenon is even more pronounced in warehouse shelving scenarios with higher gravity; loose shelves can cause lighting angle shifts, affecting product display and, in severe cases, leading to items falling and posing a safety hazard.

[0003] Secondly, the aforementioned utility model's solution lacks an active locking mechanism, relying entirely on the passive elastic snap-fit ​​of the conductive contact piece, which cannot resist lateral external force interference. When the equipment encounters handling vibration or shelf collision, the shelf may experience horizontal displacement, and the friction between the contact piece and the insulating groove can only provide limited restraint, posing a risk of detachment.

[0004] In addition, the issue of conductivity reliability cannot be ignored. The plug-in connection between the conductive contact piece and the conductive strip relies on direct surface contact to conduct current. However, the friction caused by frequent plugging and unplugging can damage the oxide film on the metal surface, forming contact resistance. At the same time, under long-term pressure and deformation, the contact interface between the conductive contact piece and the conductive strip will gradually weaken, further aggravating the degradation of conductivity and seriously affecting the stability of the lighting system.

[0005] In summary, the aforementioned problems are particularly prominent in scenarios such as supermarket shelves and exhibition windows where shelves need to be frequently replaced, which seriously restricts the practicality and safety of the products and requires further optimization and improvement. Utility Model Content

[0006] The purpose of this invention is to provide a modular shelf light with a snap-locking structure that has an independent and reliable mechanical locking structure, enabling stable installation and ensuring electrical conductivity reliability, so as to meet the higher requirements for the safety, stability and practicality of shelf lights in practical applications.

[0007] To achieve the above objectives, the present invention adopts the following solution: a modular shelf light with a snap-locking structure, comprising a shelf bracket made of metal profile, on which a track slot is provided, and a conductive strip is embedded in the track slot; a shelf that can be plugged into the track slot, the plug-in end of the shelf is provided with an anti-dislodgement component and a conductive connection part, and an illumination part is provided away from the plug-in end;

[0008] The anti-detachment component includes:

[0009] The buckle part has an elastically deformable hook structure at its end, which engages with the track slot;

[0010] The support component is movably installed within the shelf and can be moved to a locking position that restricts the elastic deformation of the hook structure;

[0011] The conductive connection portion includes:

[0012] Terminal support members are disposed at the insertion ends of the shelf;

[0013] An elastic conductive element is installed on at least one side of the terminal carrier and elastically contacts the conductive strip, and the elastic conductive element is electrically connected to the lighting unit.

[0014] This solution utilizes a snap-fit ​​part formed by an elastically deformable snap-fit ​​structure and a support part that is movably installed within the shelf and can be moved to a locking position that restricts the elastic deformation of the snap-fit ​​structure. This allows the snap-fit ​​structure of the snap-fit ​​part to engage with the track slot to achieve lateral anti-detachment locking. After the support part moves to the locking position, it restricts the elastic deformation of the snap-fit ​​structure, forming an active locking mechanism. This solves the problem in existing technologies that rely on passive elastic snap-fit ​​of conductive contact pieces and lack an active locking mechanism, making them susceptible to detachment due to lateral external force interference. It achieves the beneficial effects of enhancing the stability of mechanical connections, resisting lateral external forces, and reducing the risk of detachment.

[0015] As a further embodiment of this utility model, the latching part is a plate-shaped structure, and the hook structures are horizontally symmetrically arranged on the same side of the latching part. A collapsible groove is formed between the two hook structures for elastic deformation when the hook structure is inserted into the track slot. The support part is rotatably installed in the shelf, and its end extends into the collapsible groove. This embodiment, by making the latching part a plate-shaped structure, horizontally symmetrically arranging the hook structures on the same side of the latching part, forming a collapsible groove between the two hook structures, and rotatably installing the support part in the shelf with its end extending into the collapsible groove, allows the hook structure to achieve elastic deformation through the collapsible groove when inserted into the track slot. After insertion, the support part is rotated to restrict the deformation of the hook structure. This solves the problem of elastic attenuation and loose connection caused by the dual function of a single component in the prior art. By having an independent latching part undertake the mechanical locking function, the function of the component is not superimposed with that of the conductive component, thereby improving the durability of the locking structure and reducing the degradation of elastic performance caused by high-frequency insertion and removal.

[0016] As a further embodiment of this invention, a rotating groove with one side open is provided within the shelf corresponding to the position of the collapse groove. The support part is a strip-shaped snap-fit ​​support, which is rotatably installed within the rotating groove. The top of the rotating shaft of the snap-fit ​​support protrudes from the surface of the shelf and has an operating end. The rotation trajectory of the rotating end of the snap-fit ​​support covers the collapse groove area, and after rotation, its upper and lower sidewalls are adjacent to the inner sidewalls of the hook structure, respectively. This solution allows the user to intuitively and conveniently control the rotation of the support part through the operating end, thereby locking and unlocking the hook structure. It solves the problem of unintuitive and inconvenient locking operation in the prior art, improving user operation convenience and ensuring precise control of the locking state.

[0017] As a further embodiment of this invention, the width of the collapsible groove is greater than the thickness of the rotating end of the buckle support, and the gap between them is less than the height of the protruding part of the hook structure. This design ensures that the rotating end of the support can tightly abut against the inner wall of the hook structure after extending into the collapsible groove, accurately limiting the elastic deformation range of the hook structure, avoiding locking failure due to excessive gap or operation jamming due to insufficient gap, thus achieving the effect of improving locking reliability and ensuring structural stability.

[0018] As a further embodiment of this invention, the elastic conductive element is an elastic conductive glass bead disposed on the upper and lower sides of the terminal support member. The contact ends of the elastic conductive glass bead are elastically abutted and electrically connected to the positive and negative poles of the conductive strip in the track slot, respectively. This solution utilizes the elastic properties of the elastic conductive glass bead to achieve stable contact with the conductive strip. Compared with the plug-in connection of conductive contact pieces in the prior art, it reduces frictional loss during insertion and removal, avoids damage to the oxide film on the metal surface, solves the problem of conductive reliability, and achieves the effects of reducing contact resistance, delaying the degradation of conductive performance, and improving the stability of the lighting system.

[0019] In a preferred embodiment of this utility model, conductive slots are respectively provided on the upper and lower sides of the track slot. A flame-retardant insulating strip is inserted into the conductive slot, and the conductive strip is embedded in the flame-retardant insulating strip and integrally extruded with the flame-retardant insulating strip. This solution uses the flame-retardant insulating strip to fix the position of the conductive strip, keeping it stable within the track slot, while simultaneously isolating the conductive strip from direct contact with the outside world. This solves the problems of unstable installation and safety hazards of conductive strips in the prior art, thereby enhancing structural stability and improving safety.

[0020] As a further embodiment of this utility model, the lighting unit includes an LED light groove on the surface of the shelf, and a lighting source electrically connected to the elastic conductive glass bead is disposed within the LED light groove. This solution achieves this through...

[0021] As a further embodiment of this invention, the lighting source includes a light strip insert embedded in the LED light groove. The light strip insert has a light guide slot with an opening on its top surface. A light guide strip is inserted into the light guide slot, and an LED light strip is attached to one side of the light guide strip. This solution utilizes the light guide strip to optimize light distribution, solving the problems of easy lighting angle deviation and poor display effect in the prior art. It achieves the effects of improving light uniformity, enhancing product display effect, and avoiding lighting angle deviation.

[0022] As a preferred embodiment of this utility model, the top opening of the light guide slot is provided with a light-shielding awning extending towards the track slot, which covers part of the top of the light guide strip. The light-shielding awning reduces glare.

[0023] As a further embodiment of this utility model, the terminal carrier has a terminal receiving cavity, and carrier plates are spaced vertically within the terminal receiving cavity. Each carrier plate has a mounting hole for embedding the elastic conductive glass bead. A base box is detachably mounted on the bottom surface of the terminal carrier. Through holes corresponding to the mounting holes are provided on the top surface of the terminal carrier and the bottom surface of the base box. The diameter of the through holes is smaller than the tip of the elastic conductive glass bead. The elastic conductive glass bead is installed in the corresponding mounting hole, with its tip protruding from the corresponding through hole. This design prevents the elastic conductive glass bead from falling out and facilitates the removal of the base box for installation and maintenance. It solves the problems of unstable installation and inconvenient maintenance of conductive components in the prior art, achieving the effect of ensuring the stability of the conductive connection and improving maintenance convenience.

[0024] In summary, the advantages of this utility model compared to the prior art are as follows: This utility model uses a snap-fit ​​part and a support part to form an anti-detachment component. The snap-fit ​​structure is engaged with the track slot to achieve lateral anti-detachment locking. The support part moves to the locking position to restrict the elastic deformation of the snap-fit ​​structure, forming an active locking mechanism. This solves the problem in the prior art that relies on the passive elastic snap-fit ​​of the conductive contact piece and lacks an active locking mechanism, making it susceptible to lateral external force interference and detachment. It enhances the stability of the mechanical connection, the ability to resist lateral external force, and reduces the risk of detachment. Secondly, the snap-fit ​​part is designed as a plate structure with horizontally symmetrical snap-fit ​​structures on the same side end. A collapsible groove is formed between the two snap-fit ​​structures. The support part can be rotatably installed in the shelf and its end can extend into the collapsible groove. When the snap-fit ​​structure is inserted into the track slot, it can elastically deform through the collapsible groove. After insertion, the support part is rotated to restrict its deformation. This solves the problem in the prior art that the dual function of a single component leads to elastic decay and loose connection. By having an independent snap-fit ​​part undertake the mechanical locking function, the function of the component is not superimposed with that of the conductive component, which improves the durability of the locking structure and reduces the elastic decay caused by high-frequency insertion and removal.

[0025] In addition, elastic conductive glass beads located on the upper and lower sides of the terminal carrier are used as elastic conductive elements. Their elastic properties are used to achieve stable contact with the conductive strip. Compared with the plug-in connection of conductive contact pieces in the prior art, this reduces the friction loss of plugging and unplugging, avoids the damage of the oxide film on the metal surface, solves the problem of conductivity reliability, reduces contact resistance, delays the degradation of conductivity performance, and effectively improves the stability of the lighting system.

[0026] In addition, the lighting section has a light-shielding eave extending toward the track slot on the top opening of the light guide slot, which covers the top of the light guide strip. The light guide strip optimizes the light distribution, and the light-shielding eave reduces glare. This solves the problems of easy deviation of the lighting angle and poor display effect in the prior art, improves the uniformity of light, enhances the display effect of the goods, and avoids deviation of the lighting angle.

[0027] In summary, this utility model comprehensively solves the stability, reliability, and safety issues of existing shelf lights in frequent use scenarios by optimizing both mechanical locking and conductivity, as well as improving the safety of the lighting system and structure, thus significantly improving the practicality of the product.

These relational terms are used to facilitate the description of the relationship between some elements or features in the drawings and other elements or features. These spatial relational terms include different orientations of the device in use or operation, as well as the orientations described in the drawings.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 10 The modular shelf light with a snap-locking structure shown comprises a shelf bracket 1, a shelf 2, an anti-detachment component, a conductive connection part, and an illumination part 7. Each component achieves stable installation and reliable conductivity through precise fit. The shelf bracket 1 is made of metal profile, with a track slot 101 formed along its length inside. Conductive slots 11 are milled on the upper and lower sides of the track slot 101, and flame-retardant insulating strips 103 are inserted into the conductive slots 11. Conductive strips 102 are embedded in the flame-retardant insulating strips 103. In this embodiment, the upper and lower conductive strips 102 are the positive and negative terminals connected to the mains power, respectively. The conductive strip 102 is embedded in the surface of the flame-retardant insulating strip 103 through an integral extrusion process, forming a copper conductive strip with a width of 4mm and a thickness of 1mm. The surface is tin-plated to reduce contact resistance. The outer side of the flame-retardant insulating strip 103 is interference-fitted with the inner wall of the track slot 11, forming an integral integrated structure with the flame-retardant insulating strip 103. In this embodiment, the conductive strip 102 and the flame-retardant insulating strip 103 are integrally extruded, which not only fixes the position of the conductive strip 102, but also isolates the conductive strip 102 from contact with the outside world through the flame-retardant insulating strip 103, ensuring structural stability and safe use.

[0042] like Figures 2 to 10As shown in the diagram, in this embodiment, the insertion end of the shelf 2 integrates an anti-detachment component and a conductive connection. The anti-detachment component includes a snap-fit ​​part 3 and a support part 4 detachably disposed at the insertion end of the shelf 2. The snap-fit ​​part 3 is a plate-shaped structure with the same thickness as the shelf 2. Trapezoidal protrusion-type hook structures 301 are horizontally symmetrically arranged on the same side end of the snap-fit ​​part 3, with a protrusion height of 1.5mm. A collapsible groove 302 is formed between the two hook structures 301, allowing the hook structures 301 to elastically deform inward when inserted into the track slot 101. A rotating groove 201 with one side open is provided in the shelf 2 corresponding to the position of the collapsible groove 302. The support part 4 is a strip-shaped snap-fit ​​support 41, which is rotatably installed in the rotating groove 201. The top of the rotating shaft of the snap-fit ​​support 41 protrudes from the surface of the shelf 2 and is provided with an operating end 401. When shelf 2 is inserted into track slot 101, hook structure 301 first contacts the edge of track slot entrance. Under the action of insertion force, hook structure 301 elastically contracts inward through collapse groove 302, smoothly passing through slot entrance and inserting into slot. After insertion, hook structure 301 engages with the preset locking position 111 on the inner wall of track slot 101. At this time, the user operates the operating end 401 of support part 4 (such as rotating the circular knob on the top surface) to drive buckle support 41 to rotate around the pivot. Its rotating end extends from the rotating groove 201 in shelf 2 into collapse groove 302 (that is, the rotation trajectory of the rotating end of buckle support 41 covers the area of ​​collapse groove 302, and after rotation, its upper and lower sidewalls are adjacent to the inner sidewall of hook structure 301 respectively). The upper and lower sidewalls tightly abut against the inner sidewall of hook structure 301, restricting the elastic deformation of hook and forming active locking. The width of the collapsible groove 302 is greater than the thickness of the rotating end of the latching support 41, and the gap is less than the height of the hook protrusion, ensuring that there is neither wobbling nor jamming when locking, and precisely limiting the range of motion of the hook. It should be noted that, in addition to the above-mentioned rotation method, the latching support 41 can also use a sliding method to limit the deformation of the hook structure 301.

[0043] like Figure 4 as well as Figures 7 to 10As shown, the conductive connection part includes a terminal carrier 5, which is detachably installed on the insertion end of the shelf 2 by screws. On the upper and lower sides of the terminal carrier 5, there are elastic conductive elements 6, one end of which is in elastic contact with the conductive strip 102, and the other end of which is electrically connected to the lighting part 7 via a cable passing through the shelf 2. The terminal carrier 5 has a terminal receiving cavity 51, and carrier plates 52 are spaced vertically inside the terminal receiving cavity 51. Specifically, the elastic conductive element 6 includes an embedding hole 521 on the carrier plate 52, and an elastic conductive glass bead 61 installed in the embedding hole 521 (in this embodiment, a copper press-fit ball plunger is used as an example of the elastic conductive element 6, which consists of a ball head, a spring, and a column). To facilitate the installation and maintenance of the conductive glass bead 61, i.e., the ball-head plunger, a base box 53 is detachably provided on the bottom surface of the support member 5. The base box 53 is detachably installed on the bottom surface of the terminal support member 5 via left and right barbed buckles 531. The left and right sides of the terminal support member 5 are respectively provided with bayonet grooves 55, and the barbed buckles 531 on the left and right sides of the base box 53 are engaged in the corresponding bayonet grooves 55. The top surface of the support member 5 and the bottom surface of the base box 53 are respectively provided with through holes 54 corresponding to the embedding holes 521. The head of the conductive glass bead 61 extends out from the through holes 54 on the top surface of the terminal support member 5 and the bottom surface of the base box 53. A constant pressure is provided by the spring in the ball-head plunger to make the ball head elastically abut against the positive and negative conductive strips 102 in the track slot 101 for conduction. At the same time, the diameter of the through hole 54 is smaller than the head of the conductive glass bead to prevent it from falling out and ensure stable conductive connection.

[0044] like Figure 6 , Figure 8 and Figure 9 As shown, the lighting unit 7 is located on the upper surface of the shelf 2 away from the insertion end. Specifically, the lighting unit 7 includes an LED light groove 701 on the surface of the shelf 2. A lighting source 9 electrically connected to the elastic conductive glass bead 61 is disposed in the LED light groove 701. The lighting source 9 includes a light strip insert 8 embedded in the LED light groove 701. The light strip insert 8 is provided with a light guide slot 801 with an opening on the top surface. A light guide strip 92 is inserted into the light guide slot 801. One side of the light guide strip 92 is attached to the LED light strip 91. A light shield 802 is provided at the opening on the top surface of the light guide slot 801, extending towards the track slot and covering part of the top of the light guide strip 92 to reduce glare, optimize light distribution, avoid lighting angle deviation, and improve the product display effect.

[0045] In this embodiment, when the shelf 2 is inserted into the track slot 101, the hook structure 301 first contacts the edge of the track slot 101 entrance. Under the action of insertion force, it elastically contracts through the collapsible groove 302 and enters the slot. After it is in place, the protruding part of the hook engages in the preset locking position 111. The user rotates the operating end 401 to rotate the buckle support 41 90°, and its rotating end extends into the collapsible groove 302 to press against the inner wall of the hook, completing the mechanical locking. At the same time, the ball head of the elastic conductive glass bead 61 is in close contact with the conductive strip 102 under the action of spring force. The current is conducted to the LED light strip 91 through the plunger and wire to realize illumination. This structure solves the problems of loose connection and unreliable conductivity in the prior art through the dual mechanism of "mechanical locking + spring conduction". Moreover, the light guide strip and the light shielding eaves work together to optimize the light distribution and improve the display effect.

[0046] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
