Description

Technical Field

[0001] This utility model relates to the field of display rack technology, and in particular to a folding display rack. Background Technology

[0002] Display racks are widely used as an important display tool in various commercial displays, exhibitions, and advertising campaigns to showcase products, promotional materials, and works of art.

[0003] However, traditional display racks typically employ fixed or simple assembly structures, often resulting in the following inconveniences and limitations: Traditional display racks occupy a significant amount of space during transportation and storage. Due to their fixed structure or inflexible assembly methods, they cannot effectively reduce volume, requiring substantial space for handling and storage, increasing transportation and storage costs. This problem is particularly pronounced when frequent changes in display locations or large-scale transport of display racks are necessary. Furthermore, the assembly and disassembly of traditional display racks are cumbersome, usually requiring multiple tools and consuming considerable time and manpower, reducing work efficiency and increasing labor costs. Moreover, during assembly, the numerous components and complex connection methods make them prone to installation errors or insecure connections, affecting the stability and usability of the display rack.

[0016] The present invention achieves the following beneficial technical effects compared to the prior art:

[0017] The folding display rack provided by this utility model, when the left vertical frame is rotated counterclockwise along the first convex axis and the right vertical frame is rotated counterclockwise along the second convex axis with the help of external force, the diagonal arrangement of the first and second convex axes causes the rotated left and right vertical frames to be located in front of and behind the upper and lower frames respectively. At this time, the folding of the left and right vertical frames will no longer interfere with each other, making it easier to fold the frame.

[0018] By setting up support rods, when the display rack needs to be unfolded, the support rods can be supported in the left and right locking grooves, which not only provides support and fixation, making the frame structure more stable, but also prevents the left and right vertical frames from rotating and folding. When the display rack needs to be folded for storage, the support rods can be removed, and the left and right vertical frames can be easily rotated and folded for storage.

[0019] In use, remove the support rod from the left and right locking slots, then rotate the left and right vertical frames counterclockwise in the vertical direction so that the left and right vertical frames are in front of and behind the top and bottom frames, respectively. Then, press the left and right folding connectors towards the inside of the frame, causing the left and right vertical frames to move from the vertical position into the frame. This causes the upper and lower ends of the left vertical frame to move horizontally into the frame around the first corner connector, and simultaneously the upper and lower ends of the right vertical frame to move horizontally into the frame around the second corner connector. The movement of the left and right vertical frames from the vertical position into the frame also causes the top frame to move downwards. When the folded left and right vertical frames are parallel to the bottom frame, the frame is folded over the bottom frame, making folding and unfolding simple. This folding display rack is simple and convenient to assemble and disassemble without the need for other tools. It is easy to fold and store, with a firm connection, saving time and effort. It is also easy to carry and transport. Moreover, the overlapping parts are all connected to the frame, so they are not easy to lose. At the same time, it avoids the situation where installation errors or weak connections are easy to occur during the assembly process due to the large number of parts and the complex connection method.

[0035] This utility model provides a folding display rack, such as Figures 1-12As shown, the frame 1 includes an upper border 101 and a lower border 102 with identical structures, and a left vertical border 103 and a right vertical border 104 with identical structures. The upper end of the left vertical border 103 is rotatably connected to the left end of the upper border 101 through a first corner connector 105, and the lower end of the left vertical border 103 is rotatably connected to the left end of the lower border 102 through the first corner connector 105. The upper end of the right vertical border 104 is rotatably connected to the right end of the upper border 101 through a second corner connector 106, and the lower end of the right vertical border 104 is rotatably connected to the right end of the lower border 102 through the second corner connector 106, so that the frame 1 is a rectangular structure as a whole.

[0036] The first corner connector 105 includes a first corner body 109 and a first corner connecting part. The first corner body 109 and the first corner connecting part 110 are laterally rotatably connected. The first corner connecting part 110 is inserted into the left vertical frame. The left ends of the upper frame 101 and the lower frame 102 are respectively provided with a vertical first convex shaft 107. The first corner body 109 is rotatably connected to the first convex shaft 107. The second corner connector 106 includes a second corner body 125 and a second corner connecting part 126. The second corner body 125 and the second corner connecting part 126 are laterally rotatably connected. The second corner connecting part 126 is inserted into the right vertical frame 104. The right ends of the upper frame 101 and the lower frame 102 are respectively provided with a vertical second convex shaft 108. The second corner body 125 is rotatably connected to the second convex shaft 108.

[0037] The structure of the first corner connector 105 and the second corner connector 106 rotatably connected at both ends of the upper frame 101 is the same as that of the first corner connector 105 and the second corner connector 106 rotatably connected at both ends of the lower frame 102. The structure of the first corner connector 105 and the second corner connector 106 rotatably connected at both ends of the lower frame 102 is described in detail below.

[0038] Specifically, the left end of the lower frame 102 is provided with a first convex shaft 107, and the right end of the lower frame 102 is provided with a second convex shaft 108 arranged diagonally opposite to the first convex shaft 107. The left end of the lower frame 102 is rotatably connected to a first corner connector 105, and the right end of the lower frame 102 is rotatably connected to a second corner connector 106. The first corner connector 105 includes a first corner body 109 and a first corner connecting part 110 that are rotatably connected laterally. One end of the first corner body 109 is provided with a boss 111, and one end of the first corner connecting part 110 is inserted into the left vertical frame 103. The other end of the first corner connecting part 110 is provided with a groove 112 that matches the boss 111, so that the boss 111 can be accommodated in the groove 112. The first corner connector also includes a first pin 113 and a first limiting pin 114. The top surface of the boss 111 is arc-shaped, which facilitates the rotation of the groove 112 around the boss 111. A boss through hole 115 is provided along the axial direction of the boss 111. A first mounting hole (not shown) and a second mounting hole 116 are respectively provided on the two inner sidewalls of the groove 112. The first pin 113 can pass through the first mounting hole, the boss through hole 115 and the second mounting hole 116 in sequence, so that the first corner body 109 and the first corner connecting part 110 are connected as one unit, and the first corner connecting part... 110 can rotate laterally relative to the first corner body 109 with the first pin 113 as the rotation axis. The rotation of the first corner connecting part 110 will drive the lower end of the left vertical frame 103 to rotate. The first pin 113 has a first hole 117 at both ends. The first corner connecting part 110 has a second hole 118 corresponding to the first hole 117. The second hole 118 is located on both sides of the groove 112. The first limiting pin 114 can pass through the second hole 118 and the first hole 117 in sequence, so as to limit the first pin 113 and fix the first pin 113.

[0039] The first corner body 109 is rotatably connected to the left end of the lower frame 102 via a first convex shaft 107. Specifically, the first corner body 109 is provided with a hollow rotating sleeve 119, which is sleeved on the outer side wall of the first convex shaft 107. The first corner connector 105 also includes a second pin 120 and a second limiting pin 121. The first convex shaft 107 is provided with a convex shaft through hole 122 in the middle, which penetrates the lower frame 102. The second pin 120 can pass through the convex shaft through hole 122 and the rotating sleeve 119 in sequence. This allows the first corner body 109 to rotate vertically with the help of external force, causing it to rotate vertically relative to the lower frame 102 with the second pin 120 as the axis of rotation, thereby driving the left vertical frame 103 to rotate vertically along the first convex shaft 107. Furthermore, the lower end of the first corner body 109 matches the shape of the left end of the lower frame 102, so that when the frame 1 is unfolded, the lower end of the first corner body 109 can abut against the left end of the lower frame 102. One end of the second pin 120 is provided with a third hole 123, and the first corner body 109 is provided with a fourth hole 124 corresponding to the third hole 123. The second limiting pin 121 can pass through the fourth hole 124 and the third hole 123 in sequence, thereby limiting the second pin 120 and fixing the second pin 120.

[0040] The second corner connector 106 includes a second corner body 125 and a second corner connecting part 126 that are laterally rotatably connected. It should be noted that the connection method of the first corner connector 105 rotatably connected to the left end of the lower frame 102 and the second corner connector 106 rotatably connected to the right end of the lower frame 102 is similar, except that the second convex shaft 108 at the right end of the lower frame 102 and the first convex shaft 107 at the left end are diagonally arranged, that is, the line connecting the first convex shaft 107 and the second convex shaft 108 is located on the diagonal line of the lower frame 102. Therefore, the structure of the second corner connector 106 will not be described in detail here.

[0041] When the frame 1 is unfolded, the lower end of the left vertical frame 103 abuts against the left end of the lower frame 102, and the lower end of the right vertical frame 104 abuts against the right end of the lower frame 102. The positions of the left vertical frame 103 and the right vertical frame 104 are exactly opposite each other. When the left vertical frame 103 is rotated counterclockwise along the first convex axis 107 and the right vertical frame 104 is rotated counterclockwise along the second convex axis 108 with the help of external force, the first convex axis 107 and the second convex axis 108 are diagonally arranged so that the rotated left vertical frame 103 and the right vertical frame 104 are located in front of and behind the upper frame and the lower frame, respectively. At this time, the folding of the left vertical frame 103 and the right vertical frame 104 will no longer interfere with each other, which facilitates the folding of the frame 1.

[0042] A left-folding connector is provided in the middle of the left vertical frame, and a right-folding connector is provided in the middle of the right vertical frame. Specifically, the left vertical frame 103 is divided into a first vertical upper frame 202 and a first vertical lower frame 203 by the left-folding connector 201, and the right vertical frame 104 is divided into a second vertical upper frame 205 and a second vertical lower frame 206 by the right-folding connector 204. The left-folding connector 201 and the right-folding connector 204 have the same structure and connection method. The structure and connection method of the left-folding connector 201 are described in detail below.

[0043] The left folding connector 201 includes a middle body 207, an upper connecting part 208, and a lower connecting part 209. The upper end of the upper connecting part 208 is inserted into the first vertical upper frame 202, and the lower end of the lower connecting part 209 is inserted into the first vertical lower frame 203. Both the upper connecting part 208 and the lower connecting part 209 are laterally rotatably connected to the middle body 207, so that when the frame 1 is folded, the left vertical frame 103 will be folded from the vertical state and stored in the lower frame 102 through the left folding connector 201. Specifically, the left-folding connector 201 also includes a first insert shaft 210, a second insert shaft 211, and a third limiting pin 212. The upper end of the middle body 207 is provided with a first protrusion 213 and the lower end is provided with a second protrusion 214. The lower end of the upper connecting part 208 is provided with a first recess 215 that matches the first protrusion 213, and the upper end of the lower connecting part 209 is provided with a second recess 216 that matches the second protrusion 214. The end faces of the first protrusion 213 and the second protrusion 214 are arc-shaped, making it easier for the upper connecting part 208 and the lower connecting part 209 to rotate. A protrusion 213 is provided with a first insertion hole 217 in the horizontal direction. The inner wall of the first recess 215 is provided with a corresponding second insertion hole 218 and a third insertion hole 219. The first insertion shaft 210 passes through the second insertion hole 218, the first insertion hole 217 and the third insertion hole 219 in sequence. A second protrusion 214 is provided with a fourth insertion hole 220 in the horizontal direction. The inner wall of the second recess 216 is provided with a corresponding fifth insertion hole 221 and a sixth insertion hole 222. The second insertion shaft 211 passes through the fifth insertion hole 221, the fourth insertion hole 220 and the sixth insertion hole 222 in sequence. This allows the upper connecting part 208 to rotate around the first insert shaft 210 with the aid of external force, and the lower connecting part 209 to rotate around the second insert shaft 211. This, in turn, causes the first vertical upper frame 202 to rotate around the first insert shaft 210 and the first vertical lower frame 203 to rotate around the second insert shaft 211, thus realizing the movement of the left vertical frame 103 from a vertical state to a folded state via the left folding connector 201. Both the first insert shaft 210 and the second insert shaft 211 have a first limiting hole 223 at their ends. The upper connecting part 208 and the lower connecting part 209 each have a second limiting hole 224 corresponding to the first limiting hole 223. The third limiting pin 212 can pass through the corresponding second limiting hole 224 and the first limiting hole 223 in sequence, thereby limiting and fixing the first insert shaft 210 and the second insert shaft 211.

[0044] In this embodiment, the first pin 113, the first insert pin 210, and the second insert pin 211 are preferably straight damping pivots, so that all the pivots have a damping function. On the one hand, this ensures that the frame will not fold naturally without external force, and avoids damage to the folding point. On the other hand, it allows the frame to fold slowly, avoiding sudden drop of the frame edge that could cause frame failure, and also avoiding injury to the operator, thus ensuring the reliability of the frame folding or unfolding.

[0045] This folding display rack also includes a locking component. Specifically, the left folding connector has a left locking part, and the right folding connector has a right locking part. The locking component is connected between the left locking part and the right locking part. The locking component is used to prevent the left vertical frame 103 and the right vertical frame 104 from rotating and folding. When the locking component is removed, the left vertical frame 103 and the right vertical frame 104 can rotate and fold. In this embodiment, the locking component is a support rod 301. The left locking part is a left support platform 302 located on the inner side of the middle body of the left folding connector 201. The left support platform 302 is provided with a left locking groove 303. The right locking part is a right support platform 304 located on the inner side of the middle body of the right folding connector 204. The right support platform 304 is provided with a right locking groove 305. The two ends of the support rod 301 can be respectively engaged in the left locking groove 303 and the right locking groove 305. The left locking groove 303 and the right locking groove 305 are U-shaped grooves with a large opening and a small bottom, so as to facilitate the support rod 301 being engaged in the U-shaped groove. When the display rack needs to be unfolded, the support rod 301 can be supported in the left locking groove 303 and the right locking groove 305, which not only plays a supporting and fixing role, making the structure of the frame 1 more stable, but also prevents the left and right vertical frames from rotating and folding. When the display rack needs to be folded and stored, the support rod 301 can be removed, and the left and right vertical frames can be easily rotated and folded for storage.

[0046] It should be noted that the locking component is not limited to the structure of the support rod 301, and the locking part is not limited to the structure of the locking groove. As long as it can prevent the left and right vertical frames from rotating and folding when the frame is unfolded, and allow the left and right vertical frames to rotate and fold when the frame is folded and stored, it is acceptable.

[0047] When the left vertical frame 103 is rotated counterclockwise along the first convex axis 107 and the right vertical frame 104 is rotated counterclockwise along the second convex axis 108 with the aid of external force, due to the diagonal arrangement of the first convex axis 107 and the second convex axis 108, the left vertical frame 103 and the right vertical frame 104 will be located in front of and behind the upper and lower frames, respectively. At this time, the left vertical frame 103 can be moved from the vertical state to the inside of the frame 1 through the left folding connector 201, and the right vertical frame 104 can be moved from the vertical state to the inside of the frame 1 through the right folding connector 204, so that the upper and lower ends of the left vertical frame 103 will be connected by the first convex axis 108. The corner connector 105 moves inward toward the frame 1. At the same time, the upper and lower ends of the right vertical frame 104 move inward toward the frame 1 through the second corner connector 106. The left vertical frame 103 and the right vertical frame 104 move inward toward the frame 1 from a vertical position, which will cause the upper frame 101 to move downward. When the left vertical frame 103 and the right vertical frame 104 stop moving, that is, when the folded left vertical frame 103 and the right vertical frame 104 are parallel to the lower frame 102, the frame 1 is folded on the lower frame 102. This realizes the simple operation of folding and unfolding by folding the left vertical frame 103 and the right vertical frame 104 on the lower frame 102. This folding display rack is simple and easy to assemble and disassemble, with a firm connection. It is easy to fold and store without the need for other tools, saving time and effort. It is also easy to carry and transport. Moreover, all the overlapping parts are connected to the frame 1, so they are not easy to lose. It also avoids the situation where installation errors or loose connections are easy to occur during the assembly process due to the large number of parts and the complex connection method.

[0048] The ends of the first convex shaft 107 and the second convex shaft 108 also have an extension shaft 306, on which a damping spring 307 is sleeved. By setting the damping spring 307, the damping spring 307 can provide an upward elastic force during the unfolding of the frame 1, which is more conducive to the unfolding of the frame 1 and ensures that the frame 1 unfolds more smoothly.

[0049] Two hollow platforms 308 are provided on the top frame 101, bottom frame 102, left vertical frame 103, and right vertical frame 104. The upper connecting part 208 and lower connecting part 209 of the middle connector and the corner connecting part 110 of the corner connector are all inserted into the hollow platforms 308, ensuring the structural stability of the frame 1. A receiving groove 309 is formed between the two hollow platforms 308, which is used to receive the lighting components, which can enhance the lighting effect of the exhibition. A slot 310 is provided on the outer side of each of the two hollow platforms 308, which is used to hold the canvas or painting for display. By setting the receiving groove 309 and the slot 310, the use of fixing connectors or building connectors is also reduced.

[0050] The bottom frame 102 is provided with a base 311. The folded or unfolded frame 1 can be placed directly on site, or the base 311 can be used to fix the frame 1 in place, which improves the stability of the frame 1.

[0051] The folding display rack provided in this embodiment folds as follows: The support rod 301 is removed from the left locking groove 303 and the right locking groove 305. Then, the left vertical frame 103 and the right vertical frame 104 are rotated counterclockwise in the vertical direction, so that the left vertical frame 103 and the right vertical frame 104 are located in front of and behind the upper and lower frames, respectively. Then, the left folding connector 201 and the right folding connector 204 are pressed towards the inside of the frame 1, causing the left vertical frame 103 and the right vertical frame 104 to move from a vertical position into the inside of the frame 1. The folding process causes the upper and lower ends of the left vertical frame 103 to move horizontally inwards around the first corner connector 105 towards the frame 1. Simultaneously, it causes the upper and lower ends of the right vertical frame 104 to move horizontally inwards around the second corner connector 106 towards the frame 1. Furthermore, the movement of the left and right vertical frames 103 and 104 from their vertical positions towards the frame 1 causes the upper frame 101 to move downwards. When the folded left and right vertical frames 103 and 104 are parallel to the lower frame 102, the frame 1 is thus folded over the lower frame 102. It should be noted that the folding process is the reverse of the unfolding process; the unfolding process will not be described further here.

[0052] It should be noted that the following method can also be used when folding the display rack: first, move the left vertical frame 103 and the right vertical frame 104 toward the outside of the frame and fold them in the horizontal direction, and then rotate the folded left vertical frame 103 and the right vertical frame 104 counterclockwise in the vertical direction respectively.

[0053] It should be noted that, in order to ensure that the various edges form the best parallel position after folding, the size of each connector is adapted to the size of each edge.
