[0002] As the core carrier for displaying goods and specimens, display racks are widely used in retail, exhibitions, education and other fields.

[0003] Conventional retractable display racks have pushers installed within the shelves, connected to the shelves via springs. To restock, the pushers need to be compressed backwards, causing the shelves to recede, hindering usability. Furthermore, traditional display racks often employ a fixed, flat structure with fixed shelves or brackets, forcing viewers to adjust their stance, bend over, or tilt their heads to fully observe the exhibits. For example, when displaying furniture models, items in the back row are easily obscured by those in the front row. Similarly, when displaying art sculptures, top exhibits are difficult to view due to eye-level restrictions, severely reducing the display quality and user experience. Summary of the Invention

[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] Reference Figures 1 to 8 The present invention discloses a telescopic hinge mechanism, comprising a base 100, a folding member 200, a sliding member 300, and a limiting member 400. The base 100 is provided with a slide 110, and a front end outlet of the slide 110 is provided with a step 111. The folding member 200 includes an articulated arm 210 and a support arm 220. The articulated arm 210 is hinged to the base 100, and a limiting stopper 230 is provided between the articulated arm 210 and the support arm 220. The sliding member 300 is slidably connected to the support arm 220, and the limiting member 400 is connected to the sliding member 300. The limiting member 400 is provided with a sliding portion 410 and a limiting hook 420. The sliding portion 410 is slidably connected to the sliding groove 110, and the limiting hook 420 is connected to the rear end of the sliding portion 410. When the sliding portion 410 slides out of the exit end of the sliding groove 110, the folding member 200 is used to drive the sliding member 300 and the limiting member 400 to fold, so that the limiting hook 420 falls into the giving step 111 and is restricted by the giving step 111. The limiting hook 420 is against the giving step 111 to prevent the limiting member 400 from retreating. As the sliding member 300 continues to slide, the limiting hook 420 is hooked on the limiting baffle 230. The limiting hook 420 is used to cooperate with the giving step 111 to limit the folding angle of the folding member 200.

[0024] It should be noted that the chute 110 is provided at the right end of the extension arm 130 of the base 100, and the chute 110 and the extension arm 130 are integrally formed, that is, the chute 110 is provided at the right end of the extension arm 130, the entire extension arm 130 is a sheet metal part, an L-shaped plate structure is provided at the right end of the extension arm 130, and the horizontal section of the L-shaped is connected to the upper end of the vertical section, and the right-angle space defined by the horizontal and vertical sections of the L-shaped is the chute 110, and the limit baffle 230 is connected to the chute 110. 0 corresponds in the front and rear directions, that is, when the limiting member 400 slides in the slide groove 110, the limiting hook 420 will also slide in the same sliding direction. Therefore, in order to enable the limiting baffle 230 to interact with the limiting hook 420, it is necessary to set the limiting baffle 230 on the sliding path of the limiting hook 420, so that the limiting hook 420 hooks the limiting baffle 230, and the step 111 cooperates with the limiting hook 420 to block the sliding member 300 from retreating, thereby preventing the sliding member 300 from It can be easily retreated. It can be understood that the shelves of conventional telescopic display racks are equipped with push boards (not shown in the figure). The push boards are connected to the shelves by springs. When replenishing goods, the push boards need to be compressed backwards to replenish goods. However, this will cause the shelves to retreat, affecting the use. It should be noted that the so-called push boards push the goods forward, that is, the goods are stuck on the shelves by the push boards. After taking away a product, the push boards push the next product to the front end of the shelf, similar to a vending machine. The device automatically pushes the goods forward. The sliding part and the limit hook 420 cooperate to organize the shelf to retreat. If the shelf needs to retreat, it must be flipped back to the horizontal position before it can retreat. It can be understood that after the folding member 200 rotates, the shelf rotates downward by approximately 25 degrees (other angles can be set). The limit hook 420 hooks on the limit baffle 230, preventing the shelf from sliding down. Under the action of the step 111, the shelf cannot retract upward. This state is the state of loading or replenishing the shelf. If the shelf needs to return to the horizontal state, it needs to be rotated upward by 25 degrees to return to the second rotation state, and then pushed inward.

[0025] It can be understood that the limit hook 420 is an inclined plate connected to the rear end of the sliding part 410, and the inclined plate and the sliding part 410 are defined as a hook shape, and the limit baffle 230 is a plate extending upwardly inclined relative to the plane of the hinged arm 210. The limit baffle 230 is mainly to cooperate with the shape setting of the limit hook 420 so that the limit hook 420 can have a larger contact area when it is hooked onto the limit baffle 230.

[0026] The folding member 200, the sliding member 300 and the limiting member 400 together form a telescopic hinge mechanism, so that the sliding member 300 can be folded after sliding, and the folding member 200 can have a predetermined folding angle under the restriction of the limiting member 400. The combination of the two sets of sliding and folding movement modes can meet the requirements of folding after sliding. The mechanism is ingenious and easy to install. The limiting hook 420, the giving step 111 and the limiting baffle 230 can realize the function of limiting the folding member 200. After the display layer 600 is loaded on the sliding member 300, the storage and display of the goods can be realized. When the goods are stored, they are placed on the layer 600, and the layer 600 is in a flat posture at this time. When the goods need to be displayed, the layer 600 is dragged out and folded to tilt the layer 600 for easy display of the goods. Compared with the previous flat bracket, it has more usage methods and the usage process is simple, which is convenient for horizontal sliding and tilting display.

[0027] Reference Figures 1 to 3 The base 100 includes a support plate 120 and an extension arm 130. The extension arm 130 is disposed on the support plate 120. The support plate 120 extends in the left-right direction, while the extension arm 130 extends in the front-back direction. A chute 110 is disposed on the right side of the extension arm 130. The chute 110 extends in the front-back direction. The hinged arm 210 is hinged to the free end of the extension arm 130. The support arm 220 is disposed on the right side of the extension arm 130. The base 100 has a simple structure. The provision of the extension arm 130 provides better connection space and movement space for the folding member 200, facilitating the sliding and rotation of the folding member 200. It is understood that the support plate 120 and the extension arm 130 can be either integrally formed or welded from sheet metal. The support plate 120 is horizontally disposed in the left-right direction, while the extension arm 130 extends in the front-back direction. It is understood that the support plate 120 and the extension arm 130 are two separate sheet metal components connected by welding, and the extension arm 130 is perpendicular to the support plate 120.

[0028] Reference Figure 2 and Figure 4, the extension arm 130 is provided with a first hook structure 131, and the hinge arm 210 is provided with a second hook structure 211. The first hook structure 131 is used to cooperate with and hook the second hook structure 211. The cooperation between the first hook structure 131 and the second hook structure 211 realizes the angle locking of the folding member 200, which is convenient for operation. The first hook structure 131 includes a first arc surface 131a and a first hook head 131b, and the second hook structure 211 includes a second arc surface 211a and a second hook head 211b. The hinge arm 210 rotates to drive the second hook head 211b to rotate synchronously. The second hook head 211b is slidably connected to the first arc surface 131a, and the first hook head 131b is slidably connected to the second arc surface 211a. The first hook head 131b is used to hook the second hook head 211b, and the first hook head 131b is used to limit the rotation angle of the hinge arm 210 through the second hook head 211b. The provided arc surface structure and hook head are used to lock each other. The arc surface provides support and guidance, so that the folding process of the folding member 200 can be smoother, and the folding member 200 can be better supported. It can be understood that the curvature radii of the first arc surface 131a and the second arc surface 211a are the same, and the first hook structure 131 and the second hook structure 211 are slidably connected to each other and finally hook each other.

[0029] In some embodiments, the extension arm 130 is provided with a first side plate 132, and the hinge arm 210 is provided with a second side plate 212. The first side plate 132 and the second side plate 212 are relatively close to each other. The first arc surface 131a and the first hook head 131b are arranged on the first side plate 132, and the second arc surface 211a and the second hook head 211b are arranged on the second side plate 212. The first side plate 132 and the second side plate 212 increase the connection strength between the extension arm 130 and the hinge arm 210 and reduce the play in the left-right direction.

[0030] Refer to Figure 2, the sliding member 300 includes a support portion 310, a first carriage 320, and a second carriage 330. The support portion 310 is connected to the support arm 220. The first carriage 320 is slidably connected to the support portion 310. The second carriage 330 is slidably connected to the first carriage 320. The sliding direction of the second carriage 330 is the same as that of the first carriage 320. The limiting member 400 is connected to the second carriage 330. The sliding member 300 is provided with a telescopic sliding mechanism, which is convenient for expanding the sliding distance of the limiting member 400 connected to the sliding member 300. It can be understood that the support portion 310, the first carriage 320, and the second carriage 330 are all channel-shaped sheet metal parts. The support portion 310 and the first carriage 320 are both arranged with the notch facing upward. The second carriage 330 has the notch facing downward and is buckled in the notch of the first carriage 320. It can be understood that corresponding tracks are provided on the support portion 310 and the first carriage 320, and corresponding second sliding grooves are also provided on the first carriage 320 and the second carriage 330. The tracks and the second sliding grooves can replace the set components as needed, which belongs to a conventional replacement.

[0031] Referring to Figure 1 , Figure 2 and Figure 5 , both the sliding groove 110 and the limiting member 400 are provided in an L shape. The L-shaped sliding groove 110 and the L-shaped limiting member 400 are slidably connected through the horizontal section. The horizontal section of the limiting member 400 is the sliding portion 410. The limiting hook 420 is connected to the rear end of the horizontal section of the limiting member 400.

[0032] In some embodiments, the hinge arm 210 and the support arm 220 are integrally formed.

[0033] A display rack according to an embodiment of the second aspect of the present invention includes a support column 500, a telescopic hinge mechanism, and a shelf 600. A plurality of support columns 500 are arranged side by side. The telescopic hinge mechanisms are arranged in one-to-one correspondence with the support columns 500. Two adjacent telescopic hinge mechanisms are mirror-symmetrically arranged in the same horizontal plane. The base 100 is connected to the corresponding support column 500. The shelf 600 is connected to the sliding member 300. The limiting member 400 is connected to the lower end of the shelf 600. The shelf 600 can slide along with the sliding member 300 or fold along with the folding member 200. The shelf 600 is used to place the goods to be displayed. It can be understood that generally, the display rack includes two mirror-symmetrically arranged telescopic hinge mechanisms, and the two telescopic hinge mechanisms share a pallet 120, while the extension arms 130 belong to each other respectively, and other components are also mirror-symmetrically arranged.

[0034] This display rack has all the beneficial effects brought by the above-mentioned telescopic hinge mechanism, and will not be repeated here.

[0035] Referring to Figure 8A socket 510 is provided on the pillar 500, and the base 100 corresponds to the pillar 500 one by one. A pin 132a is provided at the rear end of the base 100, and the pin 132a is used to plug into the socket 510 to fix the corresponding base 100. The provided pillar 500 realizes the support and fixation of the base 100.

[0036] The display method is as follows: the layer plate 600 drives the sliding member 300 to slide, and the sliding member 300 slides to make the sliding portion 410 of the limiting member 400 slide in the slide groove 110. When the sliding portion 410 slides out of the exit end of the slide groove 110, the layer plate 600 is folded downward, and the limiting member 400 is also folded downward. The limiting hook 420 of the limiting member 400 falls into the clearance step 111 and abuts against the bottom of the clearance step 111. At the same time, the limiting hook 420 is hooked on the limiting baffle 230. At this time, the layer plate 600 is in a tilted state to display the goods.

[0037] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.
