[0003] Conventional telescopic display racks have push-out panels inside the shelves. These push-out panels are connected to the shelves by springs. When restocking, the push-out panels need to be compressed backward, which causes the shelves to move backward and affects usability. In addition, traditional display racks are simple flat supports. After placing the products, visitors need to adjust their viewing angle and posture to see the products clearly. Traditional display racks are not convenient for visitors to view the displayed products. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a display rack that facilitates visitors' viewing of the displayed goods.

[0005] A display rack according to an embodiment of the present utility model includes pillars, a sliding folding mechanism, and shelves. Several pillars are arranged side-by-side. The sliding folding mechanism is corresponding to each pillar and includes a base, a folding component, a connecting rod, a sliding component, and a limiting component. The base is connected to the corresponding pillar. One side of the folding component is hinged to the base. One end of the connecting rod is hinged to the other side of the folding component, and the other end of the connecting rod is slidably hinged to the base. The sliding component is slidably connected to the folding component. Shelves are connected to the sliding component, and the limiting component is connected to the side of the shelf near the base, slidably connected to the base. The sliding component drives the limiting component to slide to a predetermined position. The folding component drives the sliding component and the limiting component to fold at the predetermined position. The limiting component abuts against the base to cooperate with the connecting rod to limit the folding angle of the folding component. The shelf slides with the sliding component or folds with the folding component. The shelf is used to place the displayed goods.

[0006] It has at least the following beneficial effects: the folding component, the connecting rod, the sliding component, and the limiting component together form a sliding folding mechanism, which allows the sliding component to fold after sliding. The folding component, under the restriction of the limiting component and the connecting rod, can have a predetermined folding angle. The combination of sliding and folding movement modes satisfies the requirement of folding after sliding. The connecting rod provides restraint for the folding component. After the display shelf is mounted on the sliding component, the storage and display of goods can be realized. When the goods are stored, they are placed on the shelf, which is in a flat position. When the goods need to be displayed, the shelf is pulled out and folded to tilt the shelf, making it easier to display the goods. Compared with the previous flat support, it has more usage methods and the process is simple. It is convenient to slide horizontally and to tilt for display. The folding limiting part abuts against the bottom of the slide groove, preventing the sliding component from being pushed backward directly, increasing the convenience of use.

The limiting member is provided with a sliding support part and a folding limiting part. The sliding support part is slidably connected in the sliding groove. One end of the folding limiting part is connected to the sliding support part, and the other end of the folding limiting part is inclined and away from the sliding groove. When the sliding support part slides out of the outlet end of the sliding groove, the folding member is used to drive the sliding member and the limiting member to fold, so that the folding limiting part abuts against the bottom of the sliding groove. The folding limiting part is used to cooperate with the connecting rod to limit the folding angle of the folding member. The base structure is simple, and the extension arm provides the folding member with better connection space and movement space, facilitating the sliding and rotation of the folding member.

[0008] According to some embodiments of this utility model, the base includes a support plate and an extension arm. The support plate is provided with a connecting plate, the surface of which is perpendicular to the surface of the support plate, and an oblong hole is formed in the connecting plate.

[0031] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 6 This utility model discloses a display rack, including support columns 700, a sliding folding mechanism, and shelves 600. Several support columns 700 are arranged side-by-side. The sliding folding mechanism corresponds to each support column 700 and includes a base 100, a folding component 200, a connecting rod 300, a sliding component 400, and a limiting component 500. The base 100 is connected to the corresponding support column 700. One side of the folding component 200 is hinged to the base 100. One end of the connecting rod 300 is hinged to the other side of the folding component 200, and the other end of the connecting rod 300 is slidably hinged to the base 100. The sliding component 400 slidably connects to the folding component. 200; Shelf 600 is connected to slider 400, and limiting member 500 is connected to the side of shelf 600 near base 100. Limiting member 500 is slidably connected to base 100. Slider 400 is used to drive limiting member 500 to slide to a predetermined position. Folding member 200 is used to drive slider 400 and limiting member 500 to fold at the predetermined position. Limiting member 500 is used to abut base 100 to cooperate with connecting rod 300 to limit the folding angle of folding member 200. Shelf 600 slides with slider 400 or folds with folding member 200. Shelf 600 is used to place the displayed goods.

[0035] Understandably, the so-called sliding hinge means that the other end of the connecting rod 300 is slidably connected to the oblong hole 111a via a pin. The other end of the connecting rod 300 can rotate using the pin as a pivot, and can also slide within the length limited by the oblong hole 111a. This is to accommodate the degree of freedom required by the folding component 200 during the folding process, but without allowing the folding component 200 to fold completely. The oblong hole 111a restricts the connecting rod 300, limiting the folding angle of the folding component 200. Together with the limiting component 500, it ensures that the limiting force is evenly distributed after the folding component 200 is folded, thereby improving the folding performance of the folding component 200. The structural strength ensures the stable use of the folding member 200. In addition, the sliding support part 510 and the folding limiting part 520 are ingeniously designed. By utilizing the differential angle compensation of the folding limiting part 520, the transition from sliding to rotation is achieved. This simplifies the structure and enables the switching between two postures, making operation, manufacturing, and installation convenient. The limiting member 500 can be directly installed on the sliding member 400 or indirectly installed on the sliding member 400. Indirect installation means that the limiting member 500 is connected to the sliding member 400 through a component, such as the limiting member 500 being connected to the sliding member 400 through the shelf 600.

[0036] It should be understood that the folding component 200, connecting rod 300, sliding component 400, and limiting component 500 together form a sliding folding mechanism, allowing the sliding component 400 to fold after sliding. The folding component 200, constrained by the limiting component 500 and connecting rod 300, can achieve a predetermined folding angle. The combination of sliding and folding movement modes satisfies the requirement of folding after sliding. The connecting rod 300 serves to restrain the folding component 200. After the display shelf is mounted on the sliding component 400... It can realize the storage and display of goods. When the goods are stored, they are placed on the shelf, which is in a flat position. When the goods need to be displayed, the shelf is pulled out and folded to tilt the shelf, making it easier to display the goods. Compared with the previous flat support, it has more ways of use and the process is simple. It is convenient to slide horizontally and tilt for display. The folding limit part 520 abuts against the bottom of the slide 121, so that the sliding part 400 cannot be pushed backward directly, increasing the convenience of use. It's important to understand that conventional telescopic display racks have pusher plates (not shown in the diagram) inside the shelves. These pusher plates are connected to the shelves by springs. When restocking, the pusher plate needs to be compressed backward. However, this causes the shelves to move backward, affecting usability. It's important to clarify that the pusher plate is for pushing goods forward; goods are held in place on the shelf by the pusher plate. After one item is removed, the pusher plate pushes the next item to the front of the shelf, similar to the automatic push-forward mechanism in a vending machine. If the shelf needs to move backward, it needs to be flipped back to a horizontal position. Under the action of the connecting rod 300, the shelf stops at approximately 25 degrees to the horizontal (other angles can be set). Due to the mutual restraint of the folding limiter 520 and the slide rail 121, the shelf cannot retract upward. This state indicates the shelf is being stocked or restocked. To return the shelf to a flat position, it needs to be rotated upward 25 degrees and then pushed inward.

[0037] Reference Figure 1 , Figure 2 and Figure 5The base 100 is provided with a groove 121 and an oblong hole 111a. The folding member 200 includes a hinge arm 210 and a support arm 220. The hinge arm 210 is hinged to the base 100, and the support arm 220 is disposed in the space between the groove 121 and the oblong hole 111a. One end of the connecting rod 300 is hinged to the support arm 220, and the other end of the connecting rod 300 is slidably hinged to the oblong hole 111a. The limiting member 500 is provided with a sliding support part 510 and a folding limiting part 520. The sliding support part 510 is slidably connected in the groove 121. One end of the folding limiting part 520 is connected to the sliding support part 510, and the other end of the folding limiting part 520 is inclined and away from the groove 121. When the sliding support part 510 slides out of the outlet end of the groove 121, the folding member 200 is used for... The sliding member 400 and the limiting member 500 are folded, causing the folding limiting part 520 to abut against the bottom of the slide groove 121. The folding limiting part 520 is used to cooperate with the connecting rod 300 to limit the folding angle of the folding member 200. The base 100 has a simple structure, and the extension arm 120 provides better connection and movement space for the folding member 200, facilitating its sliding and rotation. It can be understood that the support plate 110 and the extension arm 120 can be integrally formed or welded from sheet metal. The support plate 110 is horizontally positioned in the left-right direction, while the extension arm 120 extends in the front-back direction. The connecting plate 111 also extends in the front-back direction. There is a space between the connecting plate 111 and the extension arm 120, which accommodates the support arm 220. (Refer to...) Figure 1 The support arm 220 moves from top to bottom, from sliding to folding. Before folding, the support arm 220 is placed in the space between the connecting plate 111 and the extension arm 120. After folding, the support arm 220 leaves the space.

[0038] In some embodiments, the base 100 includes a support plate 110 and an extension arm 120. The support plate 110 is provided with a connecting plate 111, the surface of which is perpendicular to the surface of the support plate 110. An oblong hole 111a is formed in the connecting plate 111. The extension arm 120 is disposed on the support plate 110. The length direction of the extension arm 120 is perpendicular to the length direction of the support plate 110 and is consistent with the length direction of the oblong hole 111a. A sliding groove 121 is disposed on the side of the extension arm 120 near the connecting plate 111 and extends along the length direction of the extension arm 120. A hinge arm 210 is hinged to the free end of the extension arm 120.

[0039] In some embodiments, the oblong hole 111a can be directly formed on the support plate 110, and the oblong hole 111a extends through the support plate 110 in the vertical direction. A sliding block is hinged to the other end of the connecting rod 300, and the sliding block is slidably connected to the oblong hole 111a in the front-back direction. This also achieves a sliding hinge connection. It is understood that both the support plate 110 and the extension arm 120 are sheet metal parts.

[0040] Reference Figure 2 The sliding member 400 includes a support portion 410, a first sliding portion 420, and a second sliding portion 430. The support portion 410 is connected to the support arm 220; the first sliding portion 420 is slidably connected to the support portion 410; the second sliding portion 430 is slidably connected to the first sliding portion 420, and the sliding direction of the second sliding portion 430 is the same as that of the first sliding portion 420. A limiting member 500 is connected to the second sliding portion 430. The sliding member 400 is configured as a telescopic sliding mechanism to facilitate expanding the sliding distance of the limiting member 500 connected to the sliding member 400. It is understandable that the support part 410, the first sliding part 420 and the second sliding part 430 are all groove-shaped sheet metal parts. The support part 410 and the first sliding part 420 are both set with the groove opening facing upwards, and the second sliding part 430 has the groove opening facing downwards and is fastened into the groove opening of the first sliding part 420. It is understandable that the support part 410 and the first sliding part 420 are provided with corresponding tracks, and the first sliding part 420 and the second sliding part 430 are also respectively provided with corresponding second sliding grooves. The tracks and second sliding grooves can be interchanged as needed, which is a conventional replacement.

[0041] In some embodiments, the connecting plate 111 is snapped onto the tray 110, which facilitates the disassembly and replacement of the connecting plate 111. It is understood that the tray 110 is provided with a snap hole, and the connecting plate 111 is provided with a snap. The connecting plate 111 is connected to the snap hole through the snap, thereby fixing the connecting plate 111 onto the tray 110.

[0042] Reference Figure 1 , Figure 2 and Figure 5 The extension arm 120 has a first plate 120a on the side near the connecting plate 111. The limiting member 500 includes a connecting part 530 and a sliding support part 510. The connecting part 530 and the sliding support part 510 are connected in an L-shape. The connecting part 530 is connected to a second sliding part 430. The first plate 120a is L-shaped. The end of the sliding support part 510 near the connecting plate 111 is connected to a folding limiting part 520. The free end of the folding limiting part 520 is inclined and located away from the horizontal section of the first plate 120a. The sliding support part 510 is slidably connected to the horizontal section of the first plate 120a. The specific structure of the slide groove 121, the sliding support part 510, and the folding limiting part 520 is simple. Each structure is defined by plates, which facilitates manufacturing and installation. It can be understood that the first plate 120a is an L-shaped plate, and the connecting part 530 and the sliding support part 510 are connected in an L-shaped plate. The so-called L-shaped plate is a sheet metal part in the form of angle steel. The connecting part 530, the sliding support part 510 and the folding limiting part 520 are all sheet metal parts.

[0043] In some embodiments, the hinge arm 210 and the support arm 220 are integrally formed.

[0044] In some embodiments, the sliding members 400 extend in the direction of the length of the shelf 600. The shelf 600 has a first side plate 610 on both sides along the length direction, and the base 100 has a second side plate 130. The second side plate 130 is arranged in a one-to-one correspondence with the first side plate 610. The first side plate 610 abuts against the inner side of the corresponding second side plate 130. The space defined by the two second side plates 130 serves as a sliding guide for the two first side plates 610. The interaction between the first side plates 610 and the second side plates 130 makes the sliding of the shelf 600 smoother and reduces the movement of the shelf 600 in the length direction.

[0045] In some embodiments, the support column 700 is provided with a socket 710, and the second side plate 130 corresponds to the support column 700. The end of the second side plate 130 near the support column 700 is provided with a pin 131, which is used to insert into the socket 710 to fix the corresponding base 100. The support column 700 provides support and fixation for the base 100.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
