Description

Technical Field

[0001] This utility model relates to the field of exhibition and display equipment technology, and in particular to a conductive track-type ultra-thin exhibition rack. Background Technology

[0002] In shopping malls, museums, or exhibitions, display racks serve as important tools for carrying goods or exhibits, and their design and function directly affect the display effect. To highlight the details of exhibits and enhance visual appeal, modern display racks often integrate lighting systems, such as installing light strips under or inside the shelves to provide localized supplemental lighting for the exhibits.

[0003] Currently, the power supply for the shelves of these illuminated display racks is typically provided by wiring embedded in the uprights and beams. While this design ensures a clean appearance, it usually results in a fixed shelf height. Once installed, the shelf positions are difficult to change, which greatly limits the flexibility of the display racks in handling exhibits of different sizes.

[0004] To meet the needs of displaying exhibits at different heights, height-adjustable display racks exist on the market. However, integrating lighting functions into these racks presents new challenges. When users need to adjust the height of electrified shelves, they must first disconnect the power, manually unplug the power cord between the shelf and the support, adjust the shelf to the new position and re-secure it, and finally reconnect the power cord. The entire process is cumbersome, time-consuming, and labor-intensive. Furthermore, repeated plugging and unplugging can easily lead to wear and tear on the wire connectors or poor contact, posing a safety hazard.

[0005] Therefore, existing technologies have failed to effectively combine convenient height adjustment mechanisms with stable power transmission functions in the design of display racks, forcing users to make trade-offs between flexible adjustment and convenient power supply. This constitutes a shortcoming in existing technologies that urgently needs to be addressed.

[0006] Therefore, this utility model proposes a conductive track-type ultra-thin display rack to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of existing conductive track-type ultra-thin display racks with lighting functions, such as complicated shelf height adjustment process, need for manual plugging and unplugging of wires, inconvenient operation and safety hazards, this utility model aims to provide a conductive track-type ultra-thin display rack with improved structure that can achieve convenient adjustment and automatic power supply.

[0008] This utility model provides a conductive track-type ultra-thin display rack, comprising: a base plate, at least two uprights, the lower ends of the uprights being fixedly connected to the base plate, the uprights having multiple conductive track holes arranged along their length, a sliding rod extending along its length being fixedly connected to the inner side of the uprights, a crossbeam, a sliding sleeve that slides with the sliding rod being fixedly connected to the back of the crossbeam, and a displacement conductive mechanism and a pressing assembly disposed in the end of the crossbeam.

[0009] The switching conductive mechanism includes a power receiving module, a conductive pin, and a first spring. The conductive pin is integrally formed on one end of the power receiving module and extends out of the crossbeam for pluggable engagement with the conductive track hole. One end of the first spring abuts against the inner wall of the crossbeam, and the other end abuts against the power receiving module.

[0010] Furthermore, the pressing assembly includes a pressing plate, a right-angle plate, and a connecting plate. The pressing plate abuts against the right-angle plate. One end of the connecting plate is fixedly connected to the right-angle plate, and the other end is fixedly connected to the power-connecting module. With this structural combination, when the pressing plate is pressed, the power-connecting module can be pulled towards the inside of the crossbeam through the right-angle plate and the connecting plate.

[0011] Preferably, the transposition conductive mechanism further includes an inclined pin, which is fixed inside the end of the crossbeam. The inclined pin has an inclined surface that abuts against the conductive pin when the crossbeam moves upward.

[0012] Preferably, the transposition conductive mechanism further includes a guide rod and a limiting plate, the power receiving module is slidably sleeved on the guide rod, and the limiting plate is fixed to the end of the crossbeam.

[0013] Preferably, the pressing assembly further includes a second spring, a reinforcing rod, and a reinforcing plate. One end of the reinforcing rod passes through the reinforcing plate and is fixedly connected to the right-angle plate. The second spring is sleeved on the reinforcing rod, and its two ends abut against the reinforcing plate and the right-angle plate, respectively.

[0014] Preferably, a display stand and a first transparent light panel are fixedly connected to the crossbeam.

[0015] Preferably, the conductive track-type ultra-thin display rack also includes another crossbeam, on which a second transparent light panel is fixedly connected.

[0016] Preferably, the conductive track-type ultra-thin display rack also includes a top plate, which is fixedly connected to the upper ends of the two uprights.

[0017] Preferably, the conductive track-type ultra-thin display rack also includes an outer plate, which is fixed to the back of the upright, and the outer plate has a movable groove reserved for the right-angle plate.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of complex height adjustment process and manual plugging and unplugging of circuits in the prior art of live display racks by setting up a displacement conductive mechanism that integrates mechanical locking and electrical contact functions, and with the help of a pressing component for unlocking. It achieves the technical effect of quickly adjusting the height of the display rack without tools, and automatically completing mechanical locking and circuit conduction after adjustment, making operation more convenient.

[0019] 2. This utility model solves the problem of tilting or jamming of the display frame beam during lifting and adjusting due to asynchronous operation on both sides by adding a guide cooperation structure of sliding rod and sliding sleeve between the upright and the crossbeam. This achieves the technical effect of ensuring a smooth and stable adjustment process and improves the structural stability and reliability of the device.

[0020] 3. This utility model solves the problem of the adjustment mechanism being exposed and affecting the overall aesthetics of the product by concealing the core functional components such as the displacement conductive mechanism and the pressing component in the internal cavity of the crossbeam and the upright. It achieves a compact structure and an ultra-thin and simple appearance, thereby enhancing the commercial value and applicable scenarios of the product. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides a conductive track-type ultra-thin display rack, which aims to solve the problem in the prior art where the height adjustment of the 5-layer plate of the electrified display rack is cumbersome and requires manual rewiring, resulting in inconvenient operation.

[0025] Reference Figure 1 The conductive track-type ultra-thin display rack constructs a stable main frame, which consists of a base plate 3 placed on the ground, two parallel uprights 4 extending upward from the lower end of the base plate 3, and a top plate 8 connected to the top of the two uprights 4. A sliding rod 207, serving as a guide rail, is fixedly installed on the inner side of the uprights 4 along their vertical direction. Multiple conductive track holes are arranged along the length of the uprights 4 on their side walls. Multiple crossbeams 10 span between the two uprights 4. A sliding sleeve 208 is fixedly connected to the back of each crossbeam 10. The sliding sleeve 208 slides in cooperation with the sliding rod 207, allowing the crossbeam 10 to move smoothly up and down along the path of the sliding rod 207. Some crossbeams 10 are fixedly supported by display racks 5 for displaying items and a first transparent light panel 6 for illumination, while another crossbeam 10 is fixedly supported by a second transparent light panel 7. Finally, an outer plate 9 for beautifying and concealing the internal structure is fixed to the back of the overall frame.

[0026] To achieve automatic locking and synchronous conductivity during the lifting and lowering process of the crossbeam 10, a displacement conductivity mechanism 1 and a pressing component 2 are built into its end.

[0027] Specific reference Figures 2 to 4Inside the transposition conductive mechanism 1, a guide rod 104 is horizontally fixed in the end cavity of the crossbeam 10. A power receiving module 103 is slidably mounted on this guide rod 104. At the end of the power receiving module 103 facing the upright 4, an integrally formed conductive pin 101 that extends out of the crossbeam 10 is provided. The size and shape of this conductive pin 101 are adapted to the conductive track hole on the upright 4. A first spring 105 is disposed between the inner wall of the crossbeam 10 and the power receiving module 103, constantly applying an outward force to the power receiving module 103. A thrust is applied to drive the conductive pin 101 to insert into the conductive track hole. To prevent the power connection module 103 from popping out excessively, a limiting plate 106 is fixed at the end face opening of the crossbeam 10 to physically block the outward travel of the power connection module 103. At the same time, an inclined pin 102 with a bevel is fixed in the cavity of the crossbeam 10. The bevel is positioned directly opposite the side of the conductive pin 101. When the crossbeam 10 is lifted upward, the conductive pin 101 will slide along the bevel, thereby passively retracting into the crossbeam 10.

[0028] The pressing assembly 2 provides a way to actively retract the conductive pin 101. In the pressing assembly 2, the pressing plate 201 is exposed on the outside of the display shelf, and its inner side abuts against one end of the right angle plate 202. One end of the connecting plate 203 is fixedly connected to the other end of the right angle plate 202, and its far end is directly fixed to the power receiving module 103 of the switching conductive mechanism 1. This constitutes a linkage mechanism from the pressing plate 201 to the power receiving module 103. In addition, a buffer reset structure composed of a reinforcing rod 205, a reinforcing plate 206, and a second spring 204 is also integrated therein. One end of the reinforcing rod 205 is fixedly connected to the right angle plate 202, and the rod body passes through the fixed reinforcing plate 206. The second spring 204 is sleeved on the reinforcing rod 205 and compressed between the reinforcing plate 206 and the right angle plate 202. A movable groove is provided on the outer plate 9 at the position corresponding to the movable range of the right angle plate 202.

[0029] To solve the above-mentioned technical problems, the crossbeam 10, through the built-in displacement conductive mechanism 1 and pressing component 2 at its end, forms a selective dynamic engagement relationship with the conductive track hole on the upright 4, which integrates mechanical locking and electrical conduction, thereby realizing rapid height adjustment without tools.

[0030] Please refer to the following carefully. Figures 2 to 4 The specific working mechanism of this structure will be explained in detail below: When the crossbeam 10 needs to be adjusted upwards, the operator directly lifts the crossbeam 10 upwards. At the instant the crossbeam 10 begins to move upwards, the conductive pin 101, which was originally extended and inserted into a conductive track hole under the pushing force of the first spring 105, will have its side contact with the inclined surface of the inclined pin 102 fixed inside the crossbeam 10 and slide along it. The guiding effect of the inclined surface will generate a component force that forces the conductive pin 101 to move inwards into the crossbeam 10. This component force overcomes the elastic force of the first spring 105 and drives the power connection module 103. Slide inward along the guide rod 104 to completely disengage the conductive pin 101 from the conductive track hole, thus unlocking it. As the crossbeam 10 continues to move upward to a new height, when the conductive pin 101 aligns with another conductive track hole above, it is no longer blocked by the oblique pin 102. The elastic energy stored in the first spring 105 is released instantly, pushing the power-connecting module 103 and the conductive pin 101 to pop outward and insert into the new conductive track hole, completing the automatic locking of the new position and the circuit connection. The whole process is continuous and automatic.

[0031] When the crossbeam 10 needs to be adjusted downwards, it needs to be actively unlocked by pressing the assembly 2. The operator presses the button 201, which pushes the right-angle plate 202. The right-angle plate 202 then applies a pulling force to the power receiving module 103 in the switching conductive mechanism 1 through the connecting plate 203 fixedly connected to it. This pulling force also overcomes the elastic force of the first spring 105, forcibly pulling the conductive pin 101 out of the conductive track hole. At the same time as the pressing action occurs, the right-angle plate 202... The reinforcing rod 205, which is fixed in place, will push the second spring 204 to compress it between the reinforcing plate 206 and the right-angle plate 202. While the button 201 is pressed, the crossbeam 10 is in the unlocked state and can slide down freely to any target position. When the button 201 is released, the second spring 204 rebounds to reset the pressing component 2 and no longer applies tension to the electrical module 103. The first spring 105 then immediately pushes the conductive pin 101 to insert into the currently aligned conductive track hole, completing the downward adjustment and locking.

[0032] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to achieve automatic unlocking when raising the crossbeam 10, please refer to... Figure 2 The inclined pin 102 in the transposition conductive mechanism 1 is fixed in the end cavity of the crossbeam 10. The inclined pin 102 has an inclined surface, and the orientation of this inclined surface forms a preset acute angle with the extension direction of the conductive pin 101, so that when the crossbeam 10 is lifted upward, it can stably abut against and guide the conductive pin 101 to retract inward.

[0033] As a preferred embodiment, to ensure the smoothness and accuracy of the reciprocating motion of the power connection module 103, please refer to... Figure 3 and Figure 4 The switching conductive mechanism 1 also includes a guide rod 104 and a limiting plate 106. The power receiving module 103 has a through hole inside and is slidably sleeved on the guide rod 104 through the through hole to limit its rotation or deflection during movement. The limiting plate 106 is fixed at the end opening of the crossbeam 10 and serves as the end stop for the power receiving module 103 to move outward.

[0034] As a preferred embodiment, to ensure that the pressing component 2 has a reliable reset function, please refer to... Figure 2 The pressing assembly 2 also includes a second spring 204, a reinforcing rod 205 and a reinforcing plate 206. One end of the reinforcing rod 205 passes through the fixedly installed reinforcing plate 206 and is fixedly connected to the right-angle plate 202. The second spring 204 is sleeved on the reinforcing rod 205, and its two ends abut against the reinforcing plate 206 and the right-angle plate 202 respectively, forming a pre-compressed elastic reset structure.

[0035] In a preferred embodiment, a display stand 5 and a first transparent light panel 6 are fixedly installed on the movable crossbeam 10. The display stand 5 is located above the crossbeam 10 to support exhibits, while the first transparent light panel 6 is integrated with the crossbeam 10 to provide lighting for the display space below.

[0036] In a preferred embodiment, in order to form a multi-layer display structure, the display rack also includes another fixed crossbeam 10, on which a second transparent light panel 7 is fixedly connected. The second transparent light panel 7 and the first transparent light panel 6 are arranged alternately in the vertical direction.

[0037] As a preferred embodiment, in order to enhance the structural strength of the overall frame, a top plate 8 is fixedly connected to the upper ends of two uprights 4, so that the entire display rack forms a stable portal frame.

[0038] In a preferred embodiment, in order to conceal the internal components and maintain a clean appearance, the outer plate 9 is fixed to the back of the upright 4, and a movable groove is provided on the outer plate 9 at the position corresponding to the right angle plate 202 for its reciprocating movement.

[0039] The working principle of this conductive track-type ultra-thin display rack is as follows: When the height of the crossbeam 10 needs to be adjusted upwards, the operator simply lifts the crossbeam 10 upwards by hand. As the crossbeam 10 begins to rise along the slide bar 207 on the upright 4, the conductive pin 101, which was originally pushed and locked in the conductive track hole by the first spring 105, will contact the inclined surface of the inclined pin 102 fixed inside the crossbeam 10. This inclined surface will exert a force on the conductive pin 101, causing it to retract inwards into the crossbeam 10. This force overcomes the elastic force of the first spring 105, causing the power-connecting module 103 to slide inwards along the guide rod 104, thereby allowing the conductive pin 101 to smoothly disengage from the conductive track hole and complete the unlocking. When the crossbeam 10 continues to rise to align with another conductive track hole above, the elastic force stored in the first spring 105 will immediately pop the power-connecting module 103 and the conductive pin 101 outwards, causing them to automatically insert into the new conductive track hole, completing the locking and conductive connection of the new position.

[0040] When the height of the crossbeam 10 needs to be adjusted downwards, the operator presses the externally mounted button 201. The button 201, through the right-angle plate 202 and the connecting plate 203, directly pulls the power-connecting module 103 inside the switching conductive mechanism 1 inwards, forcing the conductive pin 101 to disengage from the conductive track hole, thus unlocking the device. During the pressing process, the right-angle plate 202 simultaneously compresses the second spring 204. When the user presses the button 201 and moves the crossbeam 10 downwards to the target position, releasing the button 201, the rebound force of the second spring 204 will reset the entire pressing assembly 2, thereby releasing the tension on the power-connecting module 103. The first spring 105 then pushes the conductive pin 101 into the conductive track hole at the current position, completing the downward adjustment and locking. Through the synergistic action of the switching conductive mechanism 1 and the pressing assembly 2, this utility model achieves the goal of quickly adjusting the height of the electrified shelf without tools or additional wiring, solving the problem of inconvenient adjustment in the prior art.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
