Description

Technical Field

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

[0002] Folding display racks are devices used to display goods in exhibitions, shopping malls, and other settings. They have a folding function, making them easy to store and transport when not in use, effectively saving space and reducing transportation costs.

[0003] Existing folding display racks typically consist of shelves and a main body. The shelves are usually fixed to the main body using hinges or other means. One end of the hinge is fixed to the side of the shelf with screws, while the other end is connected to the main body. When the display rack needs to be folded, the user flips the shelf upwards along the axis of the hinge so that it fits against the inside of the main frame. Some display racks also have limiting slots on the main frame to hold the folded shelf in place and prevent it from shaking.

[0004] However, the inventors believe that the aforementioned prior art has the following drawbacks: the disassembly and assembly process of the shelves and the back frame is cumbersome. In actual use, in order to save disassembly and assembly time, users often fold the excess shelves directly into the main body. However, the shelves themselves have a certain weight. Compared with the design of disassembling the shelves, the main body will bear the extra weight of the excess shelves, which will reduce the weight of the products it can bear, thus reducing its effective load-bearing capacity for the products, reducing the usage effect, and reducing the amount of products displayed. Since the load-bearing capacity of the display rack is constant, overloading will pose a safety hazard. Furthermore, when multiple sets of folding display racks need to be used in combination, there is a lack of effective connection and reinforcement measures between the folding display racks. A slight external force may cause them to tip over, posing a safety hazard. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a folding display rack and a folding combination display rack, thereby overcoming the deficiencies in the background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a folding display rack, comprising a side frame, several sets of shelves, and two sets of symmetrically arranged vertical rods. A pin is provided below each shelf. The two sets of vertical rods are connected by several sets of horizontal rods. The side frame is rotatably assembled with the vertical rods and can be folded towards the horizontal rods. The shelves are rotatably assembled with the vertical rods. The pins are slidably assembled with the vertical rods. When the pins are connected to the vertical rods, the shelves fold upwards about the pins as the axis between the two sets of vertical rods. When the pins are disengaged from the vertical rods, the shelves can be detached from the vertical rods.

[0007] The pin assembly includes an outer cylinder and a pin post slidably assembled in the outer cylinder. The side wall of the shelf has a first outer hole, and the outer wall of the vertical rod has a first inner hole. When the pin assembly is connected to the vertical rod, the pin post passes through the first outer hole and the first inner hole in sequence.

[0008] The mounting plate has mounting holes on its sidewalls for mounting the pin to the layer plate.

[0009] The outer wall of the outer cylinder has a moving groove along its axial direction, and the pin post has a handle protruding outward. The handle is slidably fitted in the moving groove and at least part of the handle is exposed on the outer wall of the outer cylinder.

[0010] The movable groove is elongated and extends along the axis of the outer cylinder.

[0011] The pin also includes a spring, which is disposed inside the outer cylinder and its axis is parallel to the axis of the outer cylinder. One end of the spring is connected to the pin, and the other end of the spring is connected to the inner wall of the outer cylinder.

[0012] The outer wall of the pin is provided with a locking groove, which extends radially along the outer cylinder and communicates with the moving groove. When the pin is separated from the vertical rod, the handle is engaged with the outer wall of the locking groove.

[0013] The outer wall of the handle is provided with anti-slip texture.

[0014] It also includes a first hinge, through which the side frame and the vertical rod are rotatably assembled.

[0015] The outer wall of the side frame is provided with a support part, which abuts against the bottom wall of the shelf when the shelf is in the unfolded state.

[0016] The support portion includes a first horizontal section and a first vertical section. The first horizontal section protrudes from the outer wall of the side frame toward the shelf, and the first vertical section protrudes upward from the first horizontal section. The first horizontal section is used to abut against the bottom wall of the shelf, and the first vertical section is used to engage with the inner side wall of the shelf.

[0017] The support portion is arranged in an "L" shape.

[0018] The inner wall of the side frame is provided with two sets of side plate slots for assembling side plates, and the two sets of side plate slots are arranged opposite to each other.

[0019] It should be noted that the length of the shorter side of the side plate is slightly greater than the shortest straight distance between the two sets of opposite side plate grooves, but less than the shortest straight distance between the two sets of side walls in which the two sets of opposite side plate grooves are located.

[0020] It also includes a front plate, and the outer wall of the side frame has two sets of front plate grooves, which are arranged opposite to each other. The front plate is snapped into the inner wall of the two sets of front plate grooves.

[0021] Furthermore, the front panel is provided with one set, and the two sets of front panel slots are arranged on the top layer of the folding display rack.

[0022] The outer wall of the vertical rod is provided with a rear plate groove for assembling the rear plate, and the two sets of rear plate grooves are arranged opposite each other.

[0023] It should be noted that the length of the longer side of the rear plate is slightly greater than the shortest straight distance between the two sets of opposite rear plate grooves, but less than the shortest straight distance between the two sets of sidewalls where the two sets of opposite rear plate grooves are located.

[0024] It also includes a perforated plate, on which several sets of small holes are opened, and the perforated plate is assembled between two adjacent sets of crossbars.

[0025] The device also includes fasteners. The top and bottom walls of the perforated plate are provided with second external holes. In two adjacent sets of crossbars, the bottom wall of one set of crossbars and the top wall of the other set of crossbars are provided with second internal holes. The fasteners pass through the second external holes and the second internal holes in sequence to assemble the perforated plate between the two sets of crossbars.

[0026] The bottom wall of the side frame has a downward-protruding foot pad.

[0027] The number of layers in the plate shall be no less than three.

[0028] The number of crossbars is one more than the number of shelves.

[0029] The shelf is located below the front panel.

[0030] The side frame, the vertical bar, and the two adjacent sets of horizontal bars form a storage space, and the corresponding shelf is flipped and folded toward the storage space.

[0031] The shelf is flipped within a 90° range from the horizontal position upward to the vertical position.

[0032] A combined folding display rack includes the aforementioned folding display rack and also includes U-shaped components. The folding display rack is provided in at least two sets. The bottom wall of the vertical rod is provided with connecting holes, and the U-shaped components are respectively connected to the connecting holes of two adjacent sets of the folding display rack.

[0033] When the U-shaped component is assembled in the connecting hole, the distance between the U-shaped component and the vertical rod is less than the distance between the foot pad and the vertical rod.

[0034] The U-shaped component is interference-fitted into the connecting holes of the two sets of combined folding display racks.

[0035] The height of the U-shaped component is less than the height of the foot pad.

[0036] It also includes a first connector, which is inserted into the horizontal bar and the vertical bar of two adjacent sets of folding display racks.

[0037] It also includes a second connector, which is inserted into the side frame of two adjacent sets of folding display racks.

[0038] The beneficial effects of this utility model are as follows: by setting the pin, the shelf can be freely rotated within a 90° range, realizing flexible rotation and folding of the shelf. It also allows the shelf and the vertical rod to be quickly disassembled and assembled through the sliding of the pin. When the shelf is removed from the display rack, it can effectively improve the load-bearing capacity of the display rack and meet the diverse usage needs in different scenarios.

[0039] By movably assembling the side frames and vertical bars and allowing them to be flipped and folded, and by rotating the shelves onto the horizontal bars, the display rack can be easily folded and stored when not in use. At the same time, each shelf can rotate independently, which can meet the diverse needs of flexible shelf handling in different usage scenarios and significantly improve the flexibility of use.

[0040] By setting a support on the outer wall of the side frame, the first horizontal section abuts against the bottom wall of the shelf, and the first vertical section is engaged with the inner side wall of the shelf, the shelf is limited from multiple directions, effectively preventing the shelf from rotating or shaking downwards when unfolded, thus ensuring the stability and safety of product display.

[0041] By setting up U-shaped parts, first connectors, and second connectors, multiple folding display racks can be stably combined together, expanding the display space, meeting the display needs of different scales, and improving the flexibility and practicality of using folding display racks.

[0057] Example 1: As Figure 1-7As shown, to solve the problem of inconvenient disassembly of the rear frame and shelf 2 in existing folding display racks, this application provides a folding display rack, including a side frame 1, several sets of shelf 2, and two sets of symmetrically arranged vertical rods 3. A pin 6 is provided below each shelf 2. The two sets of vertical rods 3 are connected by several sets of horizontal rods 4. The side frame 1 is rotatably assembled with the vertical rods 3 and can be folded towards the horizontal rods 4. The shelf 2 is rotatably assembled with the vertical rods 3. The pin 6 is slidably assembled with the vertical rods 3. When the pin 6 is connected to the vertical rod 3... The shelf 2 is folded upwards around the pin 6 and between the two sets of vertical rods 3. When the pin 6 is disengaged from the vertical rod 3, the shelf 2 can be detached from the vertical rod 3. By setting the pin 6, the shelf 2 can be flexibly rotated and folded, and the shelf 2 can be easily disassembled and assembled in the folding display rack. At the same time, the pin 6 can also provide a certain support for the shelf 2, improving the stability of the shelf 2 when unfolded. After the shelf 2 is removed from the folding display rack, the load-bearing capacity of the display rack is better, meeting the needs of different usage scenarios.

[0058] To facilitate the connection of the pin 6 to the vertical rod 3 and the detachable assembly of the shelf 2, the pin 6 includes an outer cylinder 601 and a pin post 602 slidably assembled in the outer cylinder 601. The side wall of the shelf 2 has a first outer hole 201, and the outer wall of the vertical rod 3 has a first inner hole 301. When the pin 6 is connected to the vertical rod 3, the pin post 602 passes through the first outer hole 201 and the first inner hole 301 in sequence. By passing through the first outer hole 201 of the side wall of the shelf 2 and the first inner hole 301 of the outer wall of the vertical rod 3 in sequence, the pin 6 is securely connected to the vertical rod 3, ensuring the stability of the shelf 2 during use.

[0059] To enable the pin 6 to be installed on the shelf 2, the outer wall of the outer cylinder 601 is connected to a mounting plate 603. The side wall of the mounting plate 603 is provided with mounting holes 6031 for installing the pin 6 on the shelf 2. By setting the mounting plate 603 and the mounting holes 6031, it is convenient to install the pin 6 in the shelf 2 using screws or rivets, making the assembly and disassembly of the pin 6 convenient and quick, while ensuring the firmness of the pin 6 after installation. To enable the sliding assembly of the pin 602 within the outer cylinder 601, a moving groove 6011 is provided along the axial direction of the outer wall of the outer cylinder 601. A handle 604 protrudes outward from the pin 602. The handle 604 is slidably assembled in the moving groove 6011, and at least part of the handle 604 is exposed on the outer wall of the outer cylinder 601. By providing the moving groove 6011 and the handle 604, it is convenient to control the sliding of the pin 602 within the moving groove 6011 via the handle 604, making the separation and connection process of the pin 602 on the vertical rod 3 smoother and less strenuous, thus improving ease of use.

[0060] The movable groove 6011 is elongated and extends along the axis of the outer cylinder 601.

[0061] To address the issue of the pin 602 easily wobbling during use, affecting the overall assembly stability of the pin assembly 6, the pin assembly 6 further includes a spring 605. The spring 605 is disposed inside the outer cylinder 601, with its axis parallel to the axis of the outer cylinder 601. One end of the spring 605 is connected to the pin 602, and the other end is connected to the inner wall of the outer cylinder 601. By providing the spring 605, a certain elastic force is provided after the pin 602 is inserted, limiting the pin 602 in the horizontal direction, preventing wobbling, and enhancing the connection stability between the pin 602 and the vertical rod 3.

[0062] Because a spring 605 provides elastic pressure to the pin 602, and to solve the technical problem of difficulty in fixing the pin 602 after it is separated from the vertical rod 3, a locking groove 6012 is also provided on the outer wall of the pin 6. The locking groove 6012 extends radially along the outer cylinder 601 and communicates with the moving groove 6011. When the pin 6 is separated from the vertical rod 3, the handle 604 is engaged with the outer wall of the locking groove 6012. By providing the locking groove 6012, it is convenient to engage the handle 604 in the locking groove 6012 after the pin 6 is separated from the vertical rod 3, thereby fixing the pin 602 and preventing it from moving under the action of the spring 605. During subsequent assembly, it is only necessary to separate the handle 604 from the locking groove 6012, and the pin 602 will automatically extend into the vertical rod 3 under the action of the spring 605, thereby improving the ease of use.

[0063] The outer wall of the handle 604 is provided with anti-slip texture 6041. By providing anti-slip texture 6041 on the outer wall of the handle 604, the friction between the hand and the handle 604 is increased, preventing slippage during operation and improving the convenience of operation.

[0064] The system also includes a first hinge 5, through which the side frame 1 and the vertical rod 3 are rotatably assembled. The first hinge 5 connects the side frame 1 and the vertical rod 3, making it easier for the side frame 1 to rotate flexibly relative to the vertical rod 3, making the folding operation more convenient, and simplifying the assembly process.

[0065] To address the technical problem of shelf 2 easily falling off when unfolded, affecting its stability, a support part 101 is provided on the outer wall of the side frame 1. When shelf 2 is unfolded, the support part 101 abuts against the bottom wall of shelf 2. By providing the support part 101, it is easy to limit shelf 2 when it is unfolded, preventing shelf 2 from rotating downwards and ensuring the stability and safety of the displayed items.

[0066] To address the technical problem of poor limiting effect of the existing support part 101, the support part 101 includes a first horizontal section 1011 and a first vertical section 1012. The first horizontal section 1011 protrudes from the outer wall of the side frame 1 toward the shelf 2, and the first vertical section 1012 protrudes upward from the first horizontal section 1011. The first horizontal section 1011 is used to abut against the bottom wall of the shelf 2, and the first vertical section 1012 is used to engage with the inner side wall of the shelf 2. By setting the first horizontal section 1011 to abut against the bottom wall of the shelf 2 and the first vertical section 1012 to engage with the inner side wall of the shelf 2 in the support part 101, it is convenient to form multi-directional limiting, enhance the limiting effect on the shelf 2, and improve the support stability.

[0067] The support portion 101 is arranged in an "L" shape.

[0068] The inner wall of the side frame 1 is provided with two sets of side plate slots 102 for assembling side panels. The two sets of side plate slots 102 are arranged opposite each other. By opening the side plate slots 102, it is convenient to assemble side panels in the side frame 1, forming a protective structure on the side of the folding display rack to prevent items from falling from the side and improve the safety and practicality of the folding display rack.

[0069] It should be noted that the length of the shorter side of the side plate is slightly greater than the shortest straight distance between the two sets of opposite side plate grooves 102, but less than the shortest straight distance between the two sets of side walls in which the two sets of opposite side plate grooves 102 are located, so that the side plate can first be engaged into one set of side plate grooves 102, and then engaged into the other set of opposite side plate grooves 102 to complete the assembly.

[0070] The system also includes a front panel 7. The outer wall of the side frame 1 has two sets of front panel grooves 103, which are arranged opposite to each other. The front panel 7 is snapped into the inner wall of the two sets of front panel grooves 103. By setting the front panel 7 and snapping it into the front panel groove 103, the protective function of the front of the folding display rack is enhanced. At the same time, different styles of front panels 7 can be replaced according to needs to enrich the display effect. It is worth mentioning that after the front panel 7 is assembled, the side wall of the front panel 7 is snapped into the front panel groove 103, and the bottom wall of the front panel 7 abuts against the top wall of its adjacent shelf 2.

[0071] Furthermore, the front panel 7 is provided with one set, and the two sets of front panel grooves 103 are provided on the top layer of the folding display rack.

[0072] To address the technical issues of insufficient rear protection and overall integrity of the folding display rack, the outer wall of the vertical rod 3 is provided with a rear plate groove 302 for assembling the rear panel. The two sets of rear plate grooves 302 are arranged opposite each other. By opening the rear plate groove 302, it is convenient to assemble the rear panel in the vertical rod 3, forming a protective structure at the rear of the folding display rack to prevent items from falling from the back. At the same time, it makes the overall structure of the folding display rack more complete, improving its aesthetics and practicality.

[0073] It should be noted that the length of the longer side of the rear plate is slightly greater than the shortest straight distance between the two sets of opposite rear plate slots 302, but less than the shortest straight distance between the two sets of sidewalls of the two sets of opposite rear plate slots 302, so that the rear plate can first be engaged into one set of rear plate slots 302, and then engaged into the other set of opposite rear plate slots 302 to complete the assembly.

[0074] The system also includes a perforated plate 8, which has several sets of small holes on its sidewalls. The perforated plate 8 is installed between two adjacent sets of crossbars 4. By setting the perforated plate 8, on the one hand, it prevents items from falling from behind the folding display rack, improving the safety of the folding display rack. On the other hand, the holes on the perforated plate 8 can be used to fix the hooks of hanging products when it is necessary to display products such as clothing, thereby improving the functionality of the folding display rack. At the same time, in conjunction with the detachable structure design of the shelf 2, the hanging space of the perforated plate 8 can be expanded after the shelf 2 is removed.

[0075] The system also includes a fastener 9. The top and bottom walls of the perforated plate 8 are provided with second external holes 801. In two adjacent sets of crossbars 4, the bottom wall of one set of crossbars 4 and the top wall of the other set of crossbars 4 are provided with second internal holes 401. The fastener 9 passes through the second external holes 801 and the second internal holes 401 in sequence to assemble the perforated plate 8 between the two sets of crossbars 4. By setting the fastener 9, the second external holes 801, and the second internal holes 401, the perforated plate 8 is fixed in the folding display rack, improving the safety of use.

[0076] To address the technical issues of slippage and instability when placing folding display racks, foot pads 104 are provided on the bottom wall of the side frame 1 with a downward protrusion. By providing foot pads 104 on the bottom wall of the side frame 1, the friction between the folding display rack and the ground is increased, preventing the folding display rack from slipping and improving the stability of placement. At the same time, it can also play a certain role in shock absorption and protecting the ground.

[0077] The number of layers in the layer 2 is not less than three.

[0078] The number of crossbars 4 is one more than the number of shelves 2.

[0079] The layer 2 is located below the front plate 7.

[0080] The side frame 1, the vertical bar 3 and the two adjacent sets of horizontal bars 4 form a storage space 13, and the corresponding shelf 2 is flipped and folded toward the storage space 13.

[0081] The shelf 2 is flipped within a 90° range from the horizontal position upward to the vertical position.

[0082] The implementation principle of a folding display rack in this embodiment is as follows: When the folding display rack needs to be folded, the user first slides the pin 602 through the handle 604 of the pin 6 to separate it from the vertical bar 3, so that the shelf 2 flips upward and folds between the two sets of vertical bars 3. Then, the side frame 1 is rotated through the first hinge 5 so that the side frame 1 flips and folds towards the horizontal bar 4. When the folding display rack needs to be unfolded, the shelf 2 is flipped downward and fixed with the pin 6. Then the side frame 1 is unfolded so that the shelf 2 is placed on the support part 101, and the items can be displayed.

[0083] Example 2: Figure 1-10 As shown, a combined folding display rack includes the aforementioned folding display rack and a U-shaped component 10. The folding display rack is provided in at least two sets. The bottom wall of the vertical rod 3 is provided with a connecting hole 303. The U-shaped component 10 is respectively connected to the connecting holes 303 of two adjacent sets of the folding display rack. By providing the U-shaped component 10 and the connecting holes 303, it is convenient to combine multiple folding display racks together, expand the display space, meet the display needs of different scales, and improve the flexibility and practicality of the display rack.

[0084] When the U-shaped component 10 is assembled in the connecting hole 303, the distance between the U-shaped component 10 and the vertical rod 3 is less than the distance between the foot pad 104 and the vertical rod 3, so as to ensure that the foot pad 104 can always be in contact with the ground and ensure the effectiveness of the anti-slip effect.

[0085] The U-shaped component 10 is interference-fitted into the connection hole 303 of the two sets of folding display racks, so that the U-shaped component 10 will not fall off due to gravity.

[0086] The height of the U-shaped component 10 is less than the height of the foot pad 104, so that the U-shaped component 10 can be installed when both sets of folding display racks are in use.

[0087] It also includes a first connector 11, which is inserted into the horizontal bar 4 and the vertical bar 3 of two adjacent sets of folding display racks. By setting the first connector 11, it is easy to fix the horizontal bar 4 and the vertical bar 3 above the two adjacent sets of folding display racks, thereby improving the stability of the folding display rack.

[0088] The system also includes a second connector 12, which is inserted into the side frame 1 of two adjacent sets of folding display racks. By setting the second connector 12, it is easy to fix the side frame 1 above the two adjacent sets of folding display racks, thereby improving the stability of the folding display rack.

[0089] The implementation principle of a folding combination display rack in this embodiment is as follows: When assembling two sets of folding display racks, the first connector 11 is first assembled above the horizontal bar 4 and vertical bar 3 of the two adjacent sets of display racks, and then the second connector 12 is assembled above the side frame 1 of the two adjacent sets of display racks. Then, the U-shaped piece 10 is used to connect the connection hole 303 on the bottom wall of the vertical bar 3 of the two adjacent sets of display racks for assembly, so that the upper and lower sides of the two sets of folding display racks can be stably connected.
