Description

Technical Field

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

[0002] Foldable display racks are display devices that are easy to assemble quickly. They are typically assembled from multiple support frames and other components and are widely used in mobile or temporary display settings. These racks are widely used due to their portability, ease of assembly, multi-functionality, and durability.

[0003] Currently common folding display racks typically consist of a foldable outer frame. After unfolding the outer frame, additional support rods are needed to reinforce the overall structure and ensure its stability and reliability. However, these support rods are usually stored separately from the outer frame as independent components, increasing the number of parts that need to be carried and making them easy to forget during disassembly, thus causing unnecessary trouble. Furthermore, the support rods must be retrieved separately during installation, increasing the number of steps and reducing installation efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem that the outer frame and support rod of the existing folding display rack are independent of each other, resulting in more parts that are easy to forget, and at the same time, the installation steps are increased and the installation efficiency is reduced, a folding display rack is now provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a folding display rack, including an outer frame formed by an upper profile at the top, side components on both sides, and a lower profile at the bottom. The side components include at least two side profiles that are hinged to each other. The two ends of the upper profile are respectively hinged to one of the side profiles of the two side components, and the two ends of the lower profile are respectively hinged to the other side profile of the two side components. A first intermediate rod is hinged to the side profile of one side component, and a second intermediate rod is hinged to the side profile of the other side component. The first intermediate rod and the second intermediate rod are detachably connected to form a support rod for supporting the outer frame. Compared to existing technologies, this solution directly connects the various components by hinged first and second intermediate rods to the side profiles of the side components on both sides, and the opposite ends of the first and second intermediate rods are detachably connected to form support rods for supporting the outer frame. This eliminates the need for separate parts, avoids the omission of parts, and eliminates the need to remove separate parts. The operation is performed directly on the outer frame, which is simple, convenient, and improves installation efficiency.

[0006] To achieve a detachable connection between the first and second intermediate rods, in some preferred embodiments, a connecting sleeve is slidably mounted axially at the end of the first intermediate rod furthest from its hinge point. One end of the connecting sleeve is fitted onto the second intermediate rod. A first limiting mechanism is provided between the first intermediate rod and the connecting sleeve to limit the displacement range of the connecting sleeve on the first intermediate rod. A second limiting mechanism is provided between the second intermediate rod and the connecting sleeve to limit the axial displacement between the second intermediate rod and the connecting sleeve. The first limiting mechanism controls the second limiting mechanism and enables the connecting sleeve to separate and connect with the second intermediate rod. By controlling the sliding installation of the connecting sleeve on the first intermediate rod, and with the cooperation of the first and second limiting mechanisms, the connecting sleeve can be controlled to separate or fit onto the second intermediate rod, achieving a detachable connection between the first and second intermediate rods. This design is simple in structure and easy to operate.

[0007] To implement the first limiting mechanism, in some preferred embodiments, the first limiting mechanism includes a first limiting pin disposed on a first intermediate rod. A first limiting groove is formed on the connecting sleeve, and the first limiting pin is disposed within the first limiting groove. The first limiting groove includes a first guide segment and a first locking segment connected sequentially. The first guide segment is a first straight segment arranged axially along the first intermediate rod, and the first locking segment is a second straight segment arranged circumferentially along the first intermediate rod. The first locking segment is located at the end of the first guide segment furthest from the second intermediate rod. Through the cooperation of the first limiting pin on the first intermediate rod and the first limiting groove on the connecting sleeve, when the first limiting pin is within the first guide segment, it can control the axial displacement of the connecting sleeve on the first intermediate rod, separating or connecting the connecting sleeve to the second intermediate rod. When the first limiting pin is within the first locking segment, it can control the connecting sleeve to be fitted onto the second intermediate rod, thus connecting the first and second intermediate rods through the connecting sleeve, and the connecting sleeve can restrict the relative axial displacement of the first and second intermediate rods.

[0008] To prevent the first limiting pin from displacing circumferentially along the first intermediate rod in the first locking segment, in some preferred embodiments, a first slot is provided in the first locking segment to limit the circumferential displacement of the first limiting pin along the first intermediate rod. The first limiting pin engages with the first slot to effectively prevent circumferential displacement of the first limiting pin along the first intermediate rod in the first locking segment.

[0009] To ensure the coaxiality of the first and second intermediate rods during the fitting of the connecting sleeve, in some preferred embodiments, the first limiting groove further includes a mating section. This mating section is a third straight segment arranged circumferentially along the first intermediate rod, and the first guide section is located between the first locking section and the mating section. The mating section within the first limiting groove retracts the connecting sleeve onto the first intermediate rod, facilitating coaxiality of the first and second intermediate rods and making it easier for the connecting sleeve to fit onto the second intermediate rod.

[0010] In order to prevent the first limiting pin from shifting circumferentially along the first intermediate rod within the docking section, in some preferred embodiments, the docking section is provided with a second slot for limiting the first limiting pin from shifting circumferentially along the first intermediate rod.

[0011] To implement the second limiting mechanism, in some preferred embodiments, the second limiting mechanism includes a second limiting pin disposed on the second intermediate rod. The connecting sleeve has a second limiting groove, and the second limiting pin is disposed within the second limiting groove. The second limiting groove includes a second guide segment and a second locking segment connected sequentially. The second guide segment is a third straight segment arranged axially along the first intermediate rod. The first and second guide segments are arranged parallel to each other. The second locking segment is a fourth straight segment arranged circumferentially along the first intermediate rod. The second locking segment and the first locking segment are arranged parallel to each other. The second locking segment is located at the end of the second guide segment away from the second intermediate rod, and the end of the second guide segment away from the second locking segment is open. By engaging the second limiting groove on the connecting sleeve with the second limiting pin on the second intermediate rod, the connecting sleeve and the second intermediate rod can be quickly connected or separated.

[0012] The second limiting pin moves circumferentially along the first intermediate rod within the second locking section. In some preferred embodiments, the second locking section is provided with a third slot for limiting the circumferential movement of the second limiting pin along the first intermediate rod.

[0013] To facilitate the storage of the first and second intermediate rods when the outer frame is folded, and to prevent the components from colliding with each other and hindering storage, in some preferred embodiments, a first locking mechanism for locking the first intermediate rod is provided on the side profile of one side of the side assembly, and a second locking mechanism for locking the second intermediate rod is provided on the side profile of the other side of the side assembly.

[0014] In some preferred embodiments, both the first and second locking mechanisms include a locking groove, the first intermediate rod is locked in the locking groove on the side profile of one side component, and the second intermediate rod is locked in the locking groove on the side profile of the other side component.

[0015] The beneficial effects of this utility model are as follows: When using the folding display rack of this utility model, the first intermediate rod and the second intermediate rod are respectively hinged to the side profiles of the side components on both sides, and the opposite ends of the first intermediate rod and the second intermediate rod are detachably connected to each other to form a support rod for supporting the outer frame. This directly connects the various components to each other without any other independent parts, thus avoiding the omission of parts and eliminating the need to remove separate parts. The operation is performed directly on the outer frame, which is simple and convenient, improves installation efficiency, and avoids the problems of existing folding display racks where the outer frame and support rods are independent, resulting in more parts that are easy to forget, and at the same time, the increased installation steps reduce installation efficiency.

[0019] as follows Figure 1-13 As shown, a folding display rack includes an outer frame formed by an upper profile 1 at the top, side components 2 on both sides, and a lower profile 3 at the bottom. In this embodiment, the side components 2 include two side profiles 201 that are hinged to each other. Of course, in addition to two, there can be three or four side profiles 201 that are hinged to each other. The two ends of the upper profile 1 are respectively hinged to one of the side profiles 201 on both sides, and the two ends of the lower profile 3 are respectively hinged to the other side profile 201 on both sides. A first intermediate rod 401 is hinged to the side profile 201 on one side of the side component 2, and a second intermediate rod 402 is hinged to the side profile 201 on the other side of the side component 2. The first intermediate rod 401 and the second intermediate rod 402 are detachably connected to form a support rod 4 for supporting the outer frame.

[0020] A connecting sleeve 403 is slidably mounted on the end of the first intermediate rod 401 away from its hinge point along its axial direction. One end of the connecting sleeve 403 is sleeved on the second intermediate rod 402. A first limiting mechanism is provided between the first intermediate rod 401 and the connecting sleeve 403. The first limiting mechanism is used to limit the displacement range of the connecting sleeve 403 on the first intermediate rod 401 and prevent the connecting sleeve 403 from detaching from the first intermediate rod 401. A second limiting mechanism is provided between the second intermediate rod 402 and the connecting sleeve 403. The second limiting mechanism is used to limit the axial displacement between the second intermediate rod 402 and the connecting sleeve 403. The first limiting mechanism is used to control the second limiting mechanism and realize the separation and connection of the connecting sleeve 403 and the second intermediate rod 402.

[0021] The first limiting mechanism includes a first limiting pin 4011 disposed on the first intermediate rod 401, a first limiting groove 4031 formed on the connecting sleeve 403, the first limiting pin 4011 disposed within the first limiting groove 4031, and the first limiting groove 4031 containing a first guide section 40312, a first locking section 40311, and a mating section 40313 connected in sequence. The first guide section 40312 is a first straight section arranged axially along the first intermediate rod 401, the first locking section 40311 is a second straight section arranged circumferentially along the first intermediate rod 401, and the first locking section 40313... 11 is located at the end of the first guide section 40312 away from the second intermediate rod 402. The first locking section 40311 is provided with a first slot 40314 for limiting the displacement of the first limiting pin 4011 along the circumferential direction of the first intermediate rod 401. The docking section 40313 is a third straight segment arranged along the circumferential direction of the first intermediate rod 401. The first guide section 40312 is located between the first locking section 40311 and the docking section 40313. The docking section 40313 is provided with a second slot 40315 for limiting the displacement of the first limiting pin 4011 along the circumferential direction of the first intermediate rod 401.

[0022] The second limiting mechanism includes a second limiting pin 4021 disposed on the second intermediate rod 402, a second limiting groove 4032 formed on the connecting sleeve 403, the second limiting pin 4021 disposed within the second limiting groove 4032, the second limiting groove 4032 containing a second guide section 40322 and a second locking section 40321 connected in sequence, the second guide section 40322 being a third straight section arranged along the axial direction of the first intermediate rod 401, the first guide section 40312 and the second guide section 40322 being arranged parallel to each other, and the second locking section 40321 being a fourth straight section arranged circumferentially along the first intermediate rod 401. The second locking segment 40321 and the first locking segment 40311 are arranged parallel to each other. The second locking segment 40321 is located at the end of the second guide segment 40322 away from the second intermediate rod 402. The end of the second guide segment 40322 away from the second locking segment 40321 is open. The second locking segment 40321 is provided with a third slot 40323 for limiting the second limiting pin 4021 to move circumferentially along the first intermediate rod 401. Here, the first guide segment 40312 and the second guide segment 40322 are arranged parallel to each other, and the first locking segment 40311 and the second locking segment 40321 are arranged parallel to each other.

[0023] A first locking mechanism for locking the first intermediate rod 401 is provided on the side profile 201 of one side component 2, and a second locking mechanism for locking the second intermediate rod 402 is provided on the side profile 201 of the other side component 2. Both the first locking mechanism and the second locking mechanism include a slot 404. The first intermediate rod 401 is locked in the slot 404 on the side profile 201 of one side component 2, and the second intermediate rod 402 is locked in the slot 404 on the side profile 201 of the other side component 2.

[0024] The principle of this solution is as follows: During unfolding, the upper profile 1, the side components 2 on both sides, and the lower profile 3 at the bottom of the outer frame rotate relative to each other and unfold to the desired state. Then, the first intermediate rod 401 and the second intermediate rod 402 on the side components 2 are disengaged from their corresponding slots 404, making the opposite ends of the first intermediate rod 401 and the second intermediate rod 402 coaxially aligned. Next, the connecting sleeve 403 is rotated, causing the first limiting pin 4011 on the first intermediate rod 401 to disengage from the second slot 40315 in the mating section 40313 and move towards the first guide section 40312. When the first limiting pin 4011 enters the first guide section 40312, the second limiting pin 4021 on the second intermediate rod 402 aligns with the opening of the second guide section 40322. Then, the sliding connecting sleeve 403 slides, and the first limiting pin 4011 slides in the first guide section 40312. The first limiting pin 4011 gradually moves towards the first locking section 40311 until the first limiting pin 4011 corresponds to the first locking section 40311. Then, the connecting sleeve 403 is rotated so that the first limiting pin 4011 enters into the first slot 40314 of the first locking section 40311, and simultaneously drives the second limiting pin 4021 to slide in the second guide section 40322. The second limiting pin 4021 gradually moves towards the second locking section 40321 so that the second limiting pin 4021 enters into the third slot 40323 of the second locking section 40321, completing the connection of the first intermediate rod 401 and the second intermediate rod 402 and forming the support rod 4 to achieve the support of the external frame. Similarly, during separation, rotating the connecting sleeve 403 causes the first limiting pin 4011 to disengage from the first slot 40314 of the first locking section 40311 and enter the first guide section 40312. Then, the first limiting pin 4011 is controlled to slide within the first guide section 40312 until it aligns with the docking section 40313. Finally, rotating the connecting sleeve 403 causes the first limiting pin 4011 to disengage from the first slot 40314 of the docking section 40313. The second limiting pin 4021 moves out of the third slot 40323 of the second locking section 40321 and enters the second guide section 40322 from the second locking section 40321. Then the second limiting pin 4021 slides in the second guide section 40322 and gradually moves towards the opening, so that the first intermediate rod 401 and the second intermediate rod 402 are separated, completing the separation of the first intermediate rod 401 and the second intermediate rod 402.
