Description

Technical Field

[0001] This utility model relates to the field of display rack technology, and in particular to a flip-up multi-purpose display rack. Background Technology

[0002] Display racks, as a marketing tool, evolved alongside point-of-purchase (POP) advertising. They offer advantages such as being environmentally friendly, easy to transport, and quick to assemble. Placed in sales locations, they effectively showcase products, convey information, and boost sales. Compared to ordinary flat display racks, angled display racks have an angled end face to the vertical plane, creating a tilted effect in vertical space and making it easier for customers to directly view items at different heights.

[0003] However, existing slanted display racks still have some shortcomings in use. For example, their structure is usually relatively fixed, making it difficult to flexibly adjust the display angle according to actual needs, thus limiting the display effect. At the same time, the flipping function of some display racks is not well designed, making operation cumbersome and affecting the user experience. Furthermore, due to the diverse types and sizes of displayed items, traditional display racks often cannot adapt well to diverse needs, easily leading to wasted space or insufficient display. These problems, to some extent, restrict the functional expansion and application scope of display racks, thus necessitating a more flexible and practical display rack to meet market demands. Utility Model Content

[0004] To address the problem of fixed and unadjustable display angles in existing systems, this invention provides a flip-up multi-purpose display rack. By using a linkage rod, multiple layers of panels can be flipped synchronously, allowing the display rack to flexibly adjust the display angle according to actual needs, thereby improving the display effect.

[0005] This utility model provides a flip-up multi-purpose display rack, including a support frame and several storage layers. The storage layers are connected as a whole by connecting rods at both ends. The storage layers can simultaneously flip between horizontal and vertical states around the support frame via the connecting rods. The connecting rods are rotatably connected to the support frame and locked by limiting components. The multiple storage layers connected as a whole can flip synchronously under the action of the connecting rods, allowing the display angle to switch between horizontal and vertical to meet the display needs of different scenarios. Moreover, the operation is simple, and users can quickly fix or unlock the angle without tools, greatly improving the convenience of use.

[0006] Furthermore, the linkage includes a housing, a connecting rod, and cams. Cams are rotatably mounted at both ends of the shelf, and the cams are connected to each other via the connecting rod. Both the cams and the connecting rod are housed within the housing. The cooperation between the connecting rod and the cams ensures that the movement of each shelf remains highly synchronized.

[0007] Furthermore, an angle plate is provided in the middle of the outer shell, and several positioning holes are evenly spaced on the angle plate. Limiting components that match the positioning holes are set on the bracket. The limiting components adopt indexing pins, and the several positioning holes correspond to different display positions, which can be easily adjusted and fixed.

[0008] Furthermore, an auxiliary limiting mechanism is provided between the support frame and the connecting rod. This mechanism includes a support rod on the connecting rod and screws on the support frame. The support rod has several slots that match the screws. Through the cooperation of the multi-slot support rod and screws, the adjusted shelf is fixed, effectively preventing angular displacement caused by external forces and improving the stability of the display rack.

[0009] Furthermore, one of the cams is equipped with an arc-shaped groove adapted to the flipping angle, and a flexible positioning pin is installed within the arc-shaped groove. The arc-shaped groove not only enables precise control of the flipping angle, but also works with the flexible positioning pin to prevent fingers from being pinched when the shelf flips to a horizontal position.

[0010] Furthermore, the arc-shaped groove includes a first groove and a second groove with varying diameters. The width of the first groove is greater than the width of the second groove. The elastic positioning pin includes a variable-diameter shaft that is adapted to the first and second grooves. When the shelf is flipped to a horizontal position, the larger diameter section of the elastic positioning pin can quickly pass through the first groove and abut against the second groove. At this time, it can prevent the shelf from pinching between the shelf and the connecting rod, thus improving safety. The elastic positioning pin needs to be pressed so that the smaller diameter section of the elastic positioning pin is aligned with the arc-shaped groove before it can be flipped to a horizontal position.

[0011] Furthermore, the elastic locating pin also includes a spring and a hollow screw. The hollow screw is fixedly connected to the housing, and the variable-diameter shaft, placed in the arc-shaped groove, is positioned inside the hollow screw by the spring. The variable-diameter shaft can automatically reset under the action of the spring, ensuring smooth switching of the elastic locating pin between different grooves.

[0012] Furthermore, the support frame is triangular or trapezoidal, with casters at the bottom and an information board mounted on it. The triangular or trapezoidal design enhances the overall structural stability while saving space, making it suitable for various venues. The casters allow for flexible movement of the display frame, facilitating repositioning in different scenarios. The information board provides additional explanatory space for the displayed content, effectively conveying more information and improving both the display effect and practicality.

[0013] Furthermore, the various storage layers can be one or more of shelves, display platforms, and wire baskets. This diverse selection of storage layers can meet the display needs of different items, not only enhancing the functionality of the display rack but also allowing for flexible adjustments based on actual use, thus increasing its applicability and practicality.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a flip-up multi-purpose display rack. By setting up a linkage rod, multiple shelves can be flipped synchronously, allowing the display angle to switch between horizontal and vertical to meet the display needs in different scenarios. It has a simple structure and is easy to operate. Furthermore, the additional anti-pinch mechanism can prevent the user's hand from being caught in the gap between the shelf and the linkage when the shelf is flipped to a horizontal state, further improving the safety and reliability of the display rack.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] To achieve synchronized tilting and adjustment of the multi-layered panel display angle, a flip-up, multi-purpose display rack was designed, such as... Figure 1-4As shown, it includes a support frame 1 and several storage layers 2. The several storage layers 2 are connected into one unit by connecting rods 3 set at both ends. The several storage layers 2 can rotate synchronously between horizontal and vertical states around the support frame 1 by connecting rods 3. The connecting rods 3 are rotatably connected to the support frame 1 and locked by limiting members 4.

[0018] The connecting rod 3 has an internal linkage structure that can drive several shelves 2 to rotate synchronously. The connecting rod 3 is positioned by the cooperation of the angle plate 34 and the indexing pin, that is, the multiple shelves 2 are positioned. The angle plate is provided with multiple positioning holes 35, and different display angles can be selected according to the needs.

[0019] To facilitate overall movement and repositioning, the support frame 1 is triangular or trapezoidal in shape, with casters 11 at its bottom and an information board 8 mounted on it. The information board 8 and the flower bucket 9 serve as additional functional components, providing the display rack with more diverse uses and meeting the display needs of different scenarios.

[0020] like Figure 5 As shown, the various storage shelves 2 are one or more of the following: shelves, shelves, and wire baskets. The storage shelves 2 are designed to be removable, allowing users to easily add or remove shelves or replace different types of shelf structures according to their actual needs.

[0021] like Figure 6 and 7 As shown, the connecting rod 3 includes a housing 31, a linkage rod 32, and a cam 33. Cams 33 are rotatably mounted at both ends of the shelf 2, and the cams 33 are connected to each other via the linkage rod 32. Both the cams 33 and the linkage rod 32 are housed within the housing 31. Rotating shafts are fixedly mounted at both ends of the shelf 2, extending into the housing 31 and connecting to the cams 33. The linkage rod 32 connects the cams 33 at the ends of the shelf 2, enabling the connection of multiple shelf layers 2. When the display angle needs to be adjusted, simply operating the linkage rod 32 will cause all shelf layers 2 to move synchronously, greatly improving ease of use. The housing 31 is made of high-strength material, ensuring the stability of the overall structure and effectively preventing the internal components from being affected by the external environment. The cams ensure uniform force transmission during the flipping process, avoiding jamming or offset, which not only improves the functionality of the display rack but also enhances its durability and reliability, meeting the needs of long-term use.

[0022] To meet the needs of multi-angle display, an angle plate 34 is provided in the middle of the outer shell 31. Several positioning holes 35 are evenly spaced on the angle plate 34, typically 4 to 6 holes 35, corresponding to different display angles. A limiting component 4, adapted to the positioning holes 35, is provided on the support frame 1. The limiting component 4 uses an indexing pin, a common mechanical positioning element. Its core function is to achieve quick positioning and locking through the extension and retraction of the pin head. When the angle of the shelf layer 2 needs to be adjusted, the indexing pin is pulled, and the pin head retracts after compressing the internal spring. At this time, the pin head separates from the angle plate 34, and the connecting rod 3 can be rotated for adjustment. After the angle is adjusted, the external force is released, and the spring pushes the pin head back to its original position and into the positioning hole 35 on the index plate 34, completing the locking.

[0023] To ensure the overall structural strength of the display rack, an auxiliary limiting mechanism is installed between the support frame 1 and the connecting rod 3. This mechanism includes a support rod 5 mounted on the connecting rod 3 and a screw 6 mounted on the support frame 1. The support rod 5 has several slots 51 that mate with the screw 6. When the indexing pin engages with the angle plate 34 to lock the shelf 2, the support rod 5, through the engagement of the slots 51 and the screw 6, further restricts the movement range of the connecting rod 3, effectively preventing angular displacement or structural loosening due to excessive external force. This double-locking design not only improves the stability of the display rack during use but also enhances the overall structure's impact resistance, making the display rack more reliable and durable when displayed at multiple angles.

[0024] To prevent the worker's hand from being pinched during the flipping process of the storage layer 2, one of the cams 33 is provided with an arc-shaped groove 331 adapted to the flipping angle, and an elastic positioning pin 7 is provided in the arc-shaped groove 331. The arc-shaped groove 331 includes a first groove and a second groove with varying diameters, the width of the first groove being greater than the width of the second groove, and the elastic positioning pin 7 includes a variable-diameter shaft 71 adapted to the first groove and the second groove.

[0025] As the shelf 2 rotates from an inclined display state to a horizontal display state, the larger diameter section of the variable diameter shaft 71 of the elastic positioning pin 7 slides within the wider first groove of the arc-shaped groove 331. When it slides to the junction of the first and second grooves, the larger diameter section of the variable diameter shaft 71 is stuck. Figure 3As shown, the rotation of shelf 2 is stopped to prevent workers from getting their hands pinched. At this time, the worker presses the variable diameter shaft 71 of the elastic positioning pin 7 from the outside of the connecting rod 2, causing the variable diameter shaft 71 to compress the spring 72 and enter the hollow screw 73. This aligns the smaller diameter section of the variable diameter shaft 71 with the arc-shaped groove 331. The smaller diameter section of the variable diameter shaft 71 can then continue to rotate into the narrower second groove of the arc-shaped groove 331, achieving a horizontal display of the multi-shelf shelf 2. The flexible adjustment achieved through the cooperation of the variable diameter shaft 71 with the first and second grooves not only improves safety but also significantly enhances ease of use. The entire process requires no additional tools and can be easily performed with one hand, greatly reducing operating steps and time costs.

[0026] like Figure 8 As shown, the elastic positioning pin 7 also includes a spring 72 and a hollow screw 73. The hollow screw 73 is fixedly connected to the outer casing 31. The variable diameter shaft 71, placed in the arc-shaped groove 331, is positioned inside the hollow screw 73 by the spring 72. When an external force presses on the variable diameter shaft 71, it overcomes the elastic force of the spring 72 and moves into the hollow screw 73, thereby changing the relative position of the variable diameter shaft 71 and the arc-shaped groove 331. It can return to its original position when the external force is released. This design allows the elastic positioning pin 7 to flexibly switch between grooves of different widths in the arc-shaped groove 331, while ensuring the stability and durability of the structure.

[0027] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
