Description

[Technical Field]

[0001] The present invention relates to the field of folding structures, and in particular to a rotational folding structure, a folding chair, a storage box support frame, and a table. [Background Art]

[0002] A folding chair generally includes two frame members hinged to each other, with a front leg rod, a rear leg rod, a front seat rod and a rear back rod inserted onto the frame members. Among these, the front leg rod and the front seat rod are connected by an elastic cable, and the rear leg rod and the rear back rod are connected by an elastic cable.

[0003] To facilitate folding of the folding chair, the two frame members can be relatively unfolded and folded. The frame members generally include a rotating plate and a rotating arm, and the rotating plates of the two frame members are rotatably connected. According to understanding of related art, folding locking members of some folding chairs are generally mounted on the rotating plate. When folding the folding chair, it is required that one hand of a user presses the locking member on the rotating plate to release the locked state of the rotating arms, and the other hand rotates the unlocked rotating arms to achieve the purpose of folding the folding chair. Such a method results in inconvenient folding operation of the folding chair. When a folding chair is folded by adopting such a method, only one rotating arm receives force while the other rotating arm receives no force, which is likely to cause the problem of uneven force receiving when the two rotating arms are relatively folded, and is likely to cause the problem that the folding of the folding chair is not smooth. Similarly, related structures such as storage box support frames and tables adopting folding structures also have the above technical problems during folding. [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] At least one specific embodiment of the present invention aims to provide a rotating folding structure and a folding chair in order to solve the defects present in the prior art. [Means for solving the problem]

[0005] To achieve the above objectives, the following technical solutions are employed in this invention.

[0006] It has a rotating folding structure, A first rotating member and a second rotating member are connected so as to be rotatable relative to each other via a pivot shaft, A first restraining part installed on the first rotating member described above, A second restraining part is installed on the second rotating member described above, Includes an elastically returnable locking body, of which, In the deployed state, the first restraining part and the second restraining part are spatially coaxially positioned to form a restraining hole that is closed in the circumferential direction, the locking body is driven by elastic force to fit into the restraining hole and interferes with the inner wall of the restraining hole in the circumferential direction to prevent relative rotation between the first rotating member and the second rotating member, In the folded state, the locking body detaches from the restraining hole, allowing the first rotating member and the second rotating member to rotate relative to each other around the pivot axis, and the locking body contacts the outer circumferential surface of the first rotating member or the second rotating member by elastic force.

[0007] Furthermore, the direction of the locking mechanism's engagement motion is perpendicular to the axial direction of the pivot axis.

[0008] Furthermore, in the folded state, the elastic force always causes the locking body to have a tendency to move radially toward the pivot axis.

[0009] Furthermore, in the folded state, the first restraining part and the second restraining part shift, and during the conversion process from the folded state to the unfolded state, the locking body receives an elastic force and continues to press against the outer circumferential surface of the first rotating member or the second rotating member. The first rotating member and the second rotating member rotate relative to each other to a predetermined angle, the spatial positions of the first restraining part and the second restraining part align, a circumferentially closed restraining hole is automatically formed, the locking body is driven by elastic force and fitted into the restraining hole, and interferes with the inner wall of the restraining hole in the circumferential direction, completing the rotation lock.

[0010] Furthermore, in the deployed state, the first restraining part and the second restraining part are spatially coaxial, and in the process of converting from the deployed state to the folded state, a radial unlocking external force is applied to the locking body, causing the locking body to retract from the restraining hole against the elastic force. The first rotating member and the second rotating member acquire relative degrees of freedom of rotation around the rotation axis, and during the relative rotation process, the first restraining part and the second restraining part shift spatially, causing the restraining hole to be structurally eliminated and disappear. After the external force for unlocking is removed, the locking body is driven by elastic force to contact the outer circumferential surface of the first rotating member or the second rotating member, maintaining a non-interference state.

[0011] Another rotating folding structure provided by this application is, A first rotating disc including a first rotating contact surface and a first position limiting groove installed on the first rotating contact surface, A second rotating contact surface installed opposite to the first rotating contact surface, and a second rotating plate including a second position limiting groove installed on the second rotating contact surface, A pin shaft that connects the first rotating disc and the second rotating disc to enable relative rotation between them, A lock assembly including a lock pin, an elastic member, and a lock position limiting portion provided at the end of the lock pin, Among them, the first rotating disc and the second rotating disc have a relative first position and a second position, At the first position described above, the first position limiting groove and the second position limiting groove are spatially coaxially positioned to form a circumferentially closed position limiting hole, and the lock position limiting portion is inserted into the position limiting hole by the action of the elastic force of the elastic member and interferes with the inner wall of the position limiting hole in the circumferential direction to prevent relative rotation of the rotating disc. In the second position described above, the lock position limiting portion detaches from the position limiting hole, the first rotating contact surface and the second rotating contact surface can rotate relative to each other around the pin axis, and the lock position limiting portion contacts the outer circumferential surface of the first rotating plate or the second rotating plate when it returns to its original position.

[0012] Furthermore, the first rotating disc is fixedly connected to the first rotating arm, and the second rotating disc is fixedly connected to the second rotating arm, and the positions of the first and second are determined by the relative positions of the first and second rotating arms.

[0013] Furthermore, after the lock position limiting portion detaches from the position limiting hole, its end continues to be subjected to the elastic force of the elastic member and comes into contact with the outer circumferential surface of the first rotating disc or the second rotating disc.

[0014] Furthermore, the lock pin and elastic member of the above lock assembly are both mounted within the internal cavity of the first pivot arm, and the lock pin is suitable to be actuated by a trigger member movably mounted on the outside of the first pivot arm, or The locking pin and elastic member of the above-mentioned locking assembly are both mounted within the internal cavity of the second pivot arm, and the locking pin is suitable to be actuated by a trigger member that is movably mounted on the outside of the second pivot arm.

[0015] Furthermore, the trigger member is located in the end gripping region of the first or second rotating arm. The trigger member described above is configured to allow a trigger operation to be performed on the trigger member when the user grips the end gripping area and rotates the first or second rotating arm.

[0016] Furthermore, the trigger member is a sliding sleeve, The sliding sleeve is fitted onto the first or second rotating arm and connected to the lock pin via a single interlocking pin.

[0017] Furthermore, the trigger member described above is a trigger, One end of the trigger is hinged to the first or second rotating arm via a pivot pin, and the other end extends from the internal cavity of the first or second rotating arm and is connected to the lock pin via a connecting member.

Until that point, the first and second rotating arms are rotated manually to bring them close to each other, and throughout the entire folding structure, in both the unfolding and folding processes, the end gripping areas of the first and second rotating arms are grasped with both hands, respectively, and throughout the entire operation process, the ends of the first and second rotating arms are grasped with one hand each, so that both the first and second rotating arms can receive force, and there is no problem of uneven force reception or unsmooth folding.

[0028] The technical aspects of the present invention will be clearly and completely described below, in conjunction with the drawings. Of course, the embodiments described are merely a part of the embodiments of the present invention, not all embodiments. All other embodiments that a person skilled in the art could obtain based on the embodiments of the present invention without any creative effort fall within the scope of the claims of the present invention.

[0029] Example 1 Referring to Figures 1, 2, and 3, the rotating folding structure 100 includes a first frame member (or first rotating assembly) 10, a second frame member (or second rotating assembly) 20 rotatably connected to the first frame member 10, and a locking assembly 30 attached to the first frame member 10 or the second frame member 20. Among them, the first frame member 10 includes a first rotating disc (or first rotating member) 101, a first rotating arm 102 fixedly connected to the first rotating disc 101, and a first connecting arm 102a installed at the end of the first rotating arm 102. The second frame member 20 includes a second rotating disc 201, a second rotating arm 202 fixedly connected to the second rotating disc (or second rotating member) 201, and a second connecting arm 202a installed at the end of the second rotating arm 202. The first rotating disc 101 and the second rotating disc 201 are rotatably connected via a rotating shaft, for example, a pin shaft 40. Furthermore, the lock assembly 30 includes a lock pin 301 that is movably installed in the internal cavity of the first or second pivot arm 102 or second pivot arm 202, a fixing pin 302 that is fixedly connected to the first or second pivot arm 102 or second pivot arm 202 and passes through the lock pin 301, a spring 303 that is fitted to the outside of the lock pin 301 with one end connected to the fixing pin 302 and the other end in contact with the lock pin 301, an interlocking pin 304 that passes through the lock pin 301, and a sliding sleeve 305 that is fitted to the first or second pivot arm 102 or second pivot arm 202 and fixedly connected to the interlocking pin 304. Of these, the sliding sleeve 305 is configured as a trigger member, the trigger member is attached to the first rotating arm 102 or the second rotating arm 202, and the lock pin 301 is configured as a locking member, which is typically used to restrict the rotation angle of the first rotating disc 101 and the second rotating disc 201. After the trigger member is triggered, the locking member is engaged via the interlocking pin 304, thereby releasing the positional restrictions on the first rotating disc 101 and the second rotating disc 201 imposed by the locking member. A lock position limiting portion 306 is provided on the lock pin 301, and the lock position limiting portion 306 is located close to the first rotating plate 101 and the second rotating plate 201, and can limit the rotation angle of the first rotating plate 101 and the second rotating plate 201.

[0030] Furthermore, a guide groove 307 is provided in the lock pin 301, the fixing pin 302 passes through the guide groove 307, a sliding groove 308 is provided in the first rotating arm 102 or the second rotating arm 202, and the interlocking pin 304 is slidably engaged with the sliding groove 308. Of these, the guide groove 307 extends along the longitudinal direction of the lock pin 301, and the sliding groove 308 extends along the longitudinal direction of the first rotating arm 102 or the second rotating arm 202.

[0031] Furthermore, referring to Figures 4 to 8, the first rotating disc 101 is provided with a first rotating contact surface 103, and the second rotating disc 201 is provided with a second rotating contact surface 203, and the first rotating contact surface 103 and the second rotating contact surface 203 are installed facing each other, and the first rotating disc 101 and the second rotating disc 201 are rotatably connected via a pin shaft 40, after which the first rotating contact surface 103 and the second rotating contact surface 203 can rotate relative to each other around the pin shaft 40, and the first rotating contact surface 103 is provided with a first position limiting groove 104, i.e., a first restraining part, corresponding to the lock position limiting part 306, and the second rotating contact surface 203 A second position limiting groove 204, i.e., a second restraining part, is provided corresponding to the lock position limiting part 306, and the first rotating disc 101 and the second rotating disc 201 have a relative first position and a second position, and in the first position, the first position limiting groove 104 and the second position limiting groove 204 are spatially coaxially positioned and form a circumferentially closed position limiting hole (or restraining hole) 50, and the lock position limiting part 306 is inserted into the position limiting hole 50 by the action of the elastic force of the elastic member (spring 303) and interferes with the inner wall of the position limiting hole 50 in the circumferential direction, thereby preventing relative rotation between the first rotating disc 101 and the second rotating disc 201 (see Figure 5). In the second position, the lock position limiting portion 306 disengages from the position limiting hole 50, allowing the first rotating contact surface 103 and the second rotating contact surface 203 to rotate relative to each other around the pin axis 40, and when the lock position limiting portion 306 returns to its original position, it contacts the outer circumferential surface of either the first rotating plate 101 or the second rotating plate 201 (see Figure 8).

[0032] Specifically, when the first rotating arm 102 and the second rotating arm 202 are deployed relative to each other, the first rotating plate 101 and the second rotating plate 201 are in a relative first position, and the first position limiting groove 104 and the second position limiting groove 204 overlap to form a position limiting hole 50, that is, the upper and lower halves of the grooves face each other and fit together, enclosing each other to form a position limiting hole 50, and as can be seen from this, the position limiting hole 50 is formed by the side walls of the first position limiting groove 104 and the side walls of the second position limiting groove 204 enclosing each other, At that time, the first position limiting groove 104 and the second position limiting groove 204 are spatially coaxial, their central axes are the same, and due to the action of the elastic force of the spring 303, the lock position limiting portion 306 of the lock pin 301 is inserted into the position limiting hole 50, and interferes with the inner wall of the position limiting hole 50 in the circumferential direction, so that the first rotational contact surface 103 and the second rotational contact surface 203 cannot rotate relative to each other, and among these, the shape of the position limiting hole 50 and the shape of the lock position limiting portion 306 are compatible, and the diameter of the lock position limiting portion 306 is smaller than the diameter of the position limiting hole 50, When it is necessary to fold the first rotating arm 102 and the second rotating arm 202, the lock position limiting part 306 is pulled out of the position limiting hole 50, the first rotating contact surface 103 and the second rotating contact surface 203 rotate relative to each other around the pin axis 40, the first position limiting groove 104 and the second position limiting groove 204 shift relative to each other, the first rotating arm 102 and the second rotating arm 202 are folded relative to each other, and at this time the first rotating plate 101 and the second rotating plate 201 are in a relative second position, and when the lock position limiting part 306 returns due to the action of the elastic force of the spring 303, its end comes into contact with the outer circumferential surface of the first rotating plate 101 or the second rotating plate 201.

[0033] Furthermore, when the lock assembly 30 is attached to the first frame member 10, the lock pin 301 and spring 303 are attached to the internal cavity of the first pivot arm 102, the sliding sleeve 305 is fitted onto the first pivot arm 102, and after the first pivot arm 102 and the second pivot arm 202 are folded relative to each other, the first position limiting groove 104 and the second position limiting groove 204 are offset from each other, and the lock position limiting portion 306 comes into contact with the outer circumferential surface of the second pivot plate 201 due to the action of the elastic force of the spring 303. When the lock assembly 30 is attached to the second frame member 20, the lock pin 301 and spring 303 are attached to the internal cavity of the second pivot arm 202, the sliding sleeve 305 is fitted onto the second pivot arm 202, and after the first pivot arm 102 and the second pivot arm 202 are folded relative to each other, the first position limiting groove 104 and the second position limiting groove 204 are offset from each other (see Figure 6), and the lock position limiting portion 306 comes into contact with the outer circumferential surface of the first pivot plate 101 due to the action of the elastic force of the spring 303 (see Figure 8).

[0034] The following describes this embodiment in detail, along with the specific state and folding process of the folding structure 100.

[0035] Referring to Figure 9, in this embodiment, the trigger member (sliding sleeve 305) is attached to the end gripping region 60 of the first rotating arm 102 or the second rotating arm 202, and specifically, the trigger member (sliding sleeve 305) is attached to the end gripping region 60 of the second rotating arm 202 as an example. Specifically, the trigger member (sliding sleeve 305) and the locking body (locking pin 301) are installed on the outside of the same rotating arm (for example, the second rotating arm 202) and are located in the end gripping region of the second rotating arm 202, forming part of the gripping operation section W. Thus, at least a portion of the outer surface of the trigger member (sliding sleeve 305) constitutes the gripping contact surface of the gripping operation section W. When a user grips the gripping operation unit W and rotates the first rotating arm 102 and the second rotating arm 202, the user can simultaneously perform a trigger operation on the trigger member (sliding sleeve 305) while gripping the second rotating arm 202 with one hand, thereby driving the locking body (locking pin 301) and releasing the lock on the first rotating plate 101 and the second rotating plate 201.

[0036] When the folding structure 100 is in the unfolded state, the locking member (locking pin 301) locks the first rotating plate 101 and the second rotating plate 201, and when the folding structure 100 is in the folded state, the locking action of the locking member (locking pin 301) on the first rotating plate 101 and the second rotating plate 201 is released. When the folding structure 100 is converted from the unfolded state to the folded state, the gripping areas 60 at one end of the first rotating arm 102 and the second rotating arm 202 are grasped manually, and after manually pulling the trigger member (sliding sleeve 305), the trigger member (sliding sleeve 305) engages the locking member (locking pin 301) via the interlocking pin 304, the locking pin 301 slides against the fixing pin 302 via the guide groove 307, at which point the locking position limiting part 306 is pulled out from the position limiting hole 50, the spring 303 is compressed, the locking action of the locking member on the first rotating disc 101 and the second rotating disc 201 is released, and the first rotating disc 101 and the second rotating disc 201 move around the pin axis 40. The first and second rotating arms 102 and 202 can rotate relative to each other, and the first and second rotating arms 102 and 202 can be rotated by hand to bring them close together until they are in close contact with each other. Throughout the entire folding structure 100, in both the unfolding and folding processes, the end gripping areas 60 of the first and second rotating arms 102 and 202 can be grasped by both hands, respectively. Throughout the entire operation, the ends of the first and second rotating arms 102 and 202 are each grasped by one hand of the human body, and both the first and second rotating arms 102 and 202 can receive force, eliminating the problem of uneven force distribution or unsmooth folding.

[0037] When the folding structure 100 is in the folded state, the first position limiting groove 104 and the second position limiting groove 204 are misaligned with each other, and at this time the position limiting hole 50 is not formed. When the lock position limiting part 306 returns to its original position due to the action of the elastic force of the spring 303, the lock position limiting part 306 cannot find the position limiting hole 50, and its end contacts the outer circumferential surface of the first rotating disc 101 or the second rotating disc 201. Specifically, when the lock pin 301 is installed inside the first rotating arm 102, when the folding structure 100 is in the folded state, the end of the lock position limiting part 306 contacts the outer circumferential surface of the second rotating disc 201. When the lock pin 301 is installed inside the second rotating arm 202, when the folding structure 100 is in the folded state, the end of the lock position limiting part 306 contacts the outer circumferential surface of the first rotating disc 101.

[0038] When the folding structure 100 is converted from the folded state to the unfolded state, the gripping areas 60 at one end of the first rotating arm 102 and the second rotating arm 202 are grasped by hand, and the ends of the first rotating arm 102 and the second rotating arm 202 are pulled apart relative to each other. At this time, the first rotating plate 101 and the second rotating plate 201 can rotate relative to each other around the pin axis 40 until the first position limiting groove 104 and the second position limiting groove 204 overlap, that is, the upper and lower halves of the grooves face each other and fit together, enclosing and forming a position limiting hole 50. In this configuration, the position limiting hole 50 is formed by the side walls of the first position limiting groove 104 and the second position limiting groove 204 enclosing it together. At this time, the first position limiting groove 104 and the second position limiting groove 204 are spatially coaxial, and their central axes are the same. Due to the action of the elastic force of the spring 303, the lock position limiting portion 306 of the lock pin 301 is inserted into the position limiting hole 50, interfering with the inner wall of the position limiting hole 50 in the circumferential direction. This prevents the first rotational contact surface 103 and the second rotational contact surface 203 from rotating relative to each other, thus achieving the effect of locking the folding structure 100 after it has been unfolded.

[0039] Example 2 Referring to Figures 10 to 13, the difference between this embodiment and Embodiment 1 is that in this embodiment, the structure of the lock assembly 40a is different from the structure of the lock assembly in Embodiment 1. In this embodiment, the lock assembly 40a includes a lock pin 401 that is movably installed in the internal cavity of the first pivot arm 102 or the second pivot arm 202, a fixing pin 402 that is fixedly connected to the first pivot arm 102 or the second pivot arm 202 and passes through the lock pin 401, a spring 403 that is fitted to the outside of the lock pin 401 with one end connected to the fixing pin 402 and the other end in contact with the lock pin 401, a trigger 405 that is hinged to the first pivot arm 102 or the second pivot arm 202 via a pivot pin 404, and a connecting buckle 406 that connects the trigger 405 and the lock pin 401. One end of the trigger 405 is hinged to the first pivot arm 102 or the second pivot arm 202 to form a hinged end 4051, the other end of the trigger 405 extends from the internal cavity of the first pivot arm 102 or the second pivot arm 202 to form a pressure receiving end 4052, one end of the connecting buckle 406 is connected to the middle of the trigger 405, and the other end of the connecting buckle 406 is connected to the end of the lock pin 401.

[0040] Of these, the trigger 405 is configured as a trigger member, the trigger member is attached to the first rotating arm 102 or the second rotating arm 202, the lock pin 401 is configured as a locking member, and the connecting buckle 406 is configured as a connecting member, and in normal circumstances, the locking member is used to restrict the rotation angle of the first rotating disc 101 and the second rotating disc 201. After the trigger member is triggered, the locking member is engaged via the connecting buckle 406, thereby releasing the positional restrictions on the first rotating disc 101 and the second rotating disc 201 imposed by the locking member. Referring to Figures 14 and 15, a lock position limiting portion 407 is provided on the lock pin 401, and the lock position limiting portion 407 is located close to the first rotating plate 101 and the second rotating plate 201, and can limit the rotation angle of the first rotating plate 101 and the second rotating plate 201.

[0041] Furthermore, in order to facilitate the rotation of the trigger 405, when the lock assembly 40 is attached to the first rotating arm 102, a mounting opening 408 is provided on the first rotating arm 102, and when the lock assembly 40 is attached to the second rotating arm 202, a mounting opening 408 is provided on the second rotating arm 202, and the mounting opening 408 is the space necessary for the rotation of the trigger 405.

[0042] Furthermore, a guide groove 409 is provided in the lock pin 401, the fixing pin 402 passes through the guide groove 409, and the guide groove 409 extends along the length of the lock pin 401.

[0043] Furthermore, referring to Figures 16 to 19, the first rotating disc 101 is provided with a first rotating contact surface 103, and the second rotating disc 201 is provided with a second rotating contact surface 203, with the first rotating contact surface 103 and the second rotating contact surface 203 facing each other, and after the first rotating disc 101 and the second rotating disc 201 are rotatably connected via a pin shaft 40, the first rotating contact surface 103 and the second rotating contact surface 203 can rotate relative to each other around the pin shaft 40, the first rotating contact surface 103 is provided with a first position limiting groove 104 corresponding to the lock position limiting portion 407, and the second rotating contact surface 203 is provided with a second position limiting groove 204 corresponding to the lock position limiting portion 407.

[0044] When the first rotating arm 102 and the second rotating arm 202 are deployed relative to each other, the first position limiting groove 104 and the second position limiting groove 204 are spatially coaxially positioned to form a position limiting hole 50, and due to the action of the elastic force of the spring 403, the lock position limiting portion 407 of the lock pin 401 is inserted into the position limiting hole 50, preventing the first rotating contact surface 103 and the second rotating contact surface 203 from rotating relative to each other, and the shape of the position limiting hole 50 and the shape of the lock position limiting portion 407 are matched, and the diameter of the lock position limiting portion 407 is smaller than the diameter of the position limiting hole 50. When the first rotating arm 102 and the second rotating arm 202 are folded relative to each other, the pressure-receiving end 4052 of the trigger 405 is pulled manually, causing the trigger 405 to rotate with the rotating pin 404 as the support point. During the rotation process, the trigger 405 is driven to retract the lock pin 401 via the connecting buckle 406, and the lock position limiting portion 407 at the end of the lock pin 401 is pulled out from the position limiting hole 50. When the positional restrictions on the first rotating disc 101 and the second rotating disc 201 are released, the first rotating contact surface 103 and the second rotating contact surface 203 can rotate relative to each other around the pin axis 40, the first position limiting groove 104 and the second position limiting groove 204 shift relative to each other, and the locked position limiting part 407 returns to its original position due to the action of the elastic force of the spring 403, its end comes into contact with the outer circumferential surface of the first rotating disc 101 or the second rotating disc 201.

[0045] Specifically, when the lock assembly 40 is attached to the first frame member 10, after the first rotating arm 102 and the second rotating arm 202 are folded relative to each other, the first position limiting groove 104 and the second position limiting groove 204 are offset from each other, and the lock position limiting portion 407 comes into contact with the outer circumferential surface of the second rotating plate 201 due to the action of the elastic force of the spring 403. When the lock assembly 40 is attached to the second frame member 20, the first rotating arm 102 and the second rotating arm 202 are folded relative to each other, the first position limiting groove 104 and the second position limiting groove 204 are offset from each other, and the lock position limiting portion 407 comes into contact with the outer circumferential surface of the first rotating plate 101 due to the action of the elastic force of the spring 403.

[0046] The following describes this embodiment in detail, along with the specific state and folding process of the folding structure 100.

[0047] Referring to Figure 19, in this embodiment, the trigger member (trigger 405) is attached to the end gripping region 60 of the first rotating arm 102 or the second rotating arm 202. Specifically, the trigger member (trigger 405) and the locking body (lock pin 301) are installed on the outside of the same rotating arm (for example, the second rotating arm 202) and are located in the end gripping region of the second rotating arm 202, forming part of the gripping operation section W, so that at least a portion of the outer surface of the trigger member (trigger 405) forms the gripping contact surface of the gripping operation section W. When a user grips the gripping operation unit W and rotates the first rotating arm 102 and the second rotating arm 202, the user can simultaneously perform a trigger operation on the trigger member (trigger 405) while gripping the second rotating arm 202 with one hand, thereby driving the locking body (lock pin 301) and releasing the lock on the first rotating plate 101 and the second rotating plate 201.

[0048] When the folding structure 100 is in the unfolded state, the locking member (locking pin 401) locks the first rotating plate 101 and the second rotating plate 201, and when the folding structure 100 is in the folded state, the locking action of the locking member (locking pin 401) on the first rotating plate 101 and the second rotating plate 201 is released. When the folding structure 100 is converted from the unfolded state to the folded state, the gripping areas 60 at one end of the first rotating arm 102 and the second rotating arm 202 are grasped manually, and after manually pulling the trigger member (trigger 405), the trigger member (trigger 405) engages the locking member (lock pin 401) via the connecting buckle 406, the lock pin 401 slides against the fixing pin 402 via the guide groove 409, at which point the lock position limiting part 407 is pulled out from the position limiting hole 50, the spring 403 is compressed, the locking action of the locking member on the first rotating disc 101 and the second rotating disc 201 is released, and the first rotating disc 101 and the second rotating disc 201 move relative to each other around the pin axis 40. The first and second rotating arms 102 and 202 can be rotated by hand until they are in close contact with each other. Throughout the entire folding structure 100, during both the unfolding and folding processes, the end gripping areas 60 of the first and second rotating arms 102 and 202 can be grasped by both hands. Throughout the entire operation, the ends of the first and second rotating arms 102 and 202 are each grasped by one hand of the human body, and both the first and second rotating arms 102 and 202 can receive force, eliminating the problem of uneven force distribution or unsmooth folding.

[0049] When the folding structure 100 is in the folded state, the first position limiting groove 104 and the second position limiting groove 204 are misaligned with each other, and at this time the position limiting hole 50 is not formed. When the lock position limiting part 407 returns to its original position due to the action of the elastic force of the spring 403, the lock position limiting part 407 cannot find the position limiting hole 50, and its end contacts the outer circumferential surface of the first rotating disc 101 or the second rotating disc 201. Specifically, when the lock pin 401 is installed inside the first rotating arm 102, when the folding structure 100 is in the folded state, the end of the lock position limiting part 407 contacts the outer circumferential surface of the second rotating disc 201. When the lock pin 401 is installed inside the second rotating arm 202, when the folding structure 100 is in the folded state, the end of the lock position limiting part 407 contacts the outer circumferential surface of the first rotating disc 101.

[0050] When the folding structure 100 is converted from the folded state to the unfolded state, the gripping areas 60 at one end of the first rotating arm 102 and the second rotating arm 202 are grasped by hand, and the ends of the first rotating arm 102 and the second rotating arm 202 are pulled apart relative to each other. At this time, the first rotating plate 101 and the second rotating plate 201 can rotate relative to each other around the pin axis 40 until the first position limiting groove 104 and the second position limiting groove 204 are spatially coaxially positioned to form a position limiting hole 50. Due to the action of the elastic force of the spring 403, the lock position limiting portion 407 of the lock pin 401 is inserted into the position limiting hole 50, preventing the first rotating contact surface 103 and the second rotating contact surface 203 from rotating relative to each other, and thus the folding structure 100 can achieve the effect of locking after unfolding.

[0051] Example 3 Referring to Figures 20 to 23, and based on a similar technical concept, the embodiment of the present application is the same as the rotating folding structure 100 in Embodiment 1 or Embodiment 2 above, The front leg rod 210, rear leg rod 220, front seat rod 230, and rear back rod 240 are inserted into the first connecting arm 102a and the second connecting arm 202a, respectively. A first cable 250, one end of which is inserted into and connected to the front leg rod 210, and the other end of which is inserted into and connected to the front seat rod 230, A second cable 260, one end of which is inserted into and connected to the rear leg rod 220, and the other end of which is inserted into and connected to the rear back rod 240, The present invention provides a folding chair 200, which includes a seat pocket 270 whose four corners are each supported by two front seat rods 230 and two rear seat rods 240.

[0052] It should be explained that the drawing of the folding chair 200 in this embodiment only shows the rotating folding structure 100 in Embodiment 1. After the folding chair 200 adopts the above folding structure 100, the entire folding chair 200, when folding and unfolding, has the ends of the first rotating arm 102 and the second rotating arm 202 each grasped by one hand of the human body, the receiving force is uniform, and folding is smooth.

[0053] Furthermore, in this embodiment, the front leg rod 210, rear leg rod 220, front seat rod 230, and rear back rod 240 of the first rotating arm 102 are all connected via the easy-to-deploy structure 300, and similarly, the front leg rod 210, rear leg rod 220, front seat rod 230, and rear back rod 240 of the second rotating arm 202 are all connected via the easy-to-deploy structure 300.

[0054] Referring to Figures 24 to 27, the easily deployable structure 300 includes a support rod 320 that is rotatably attached to the mounting body 310, the mounting body 310 having an insertion portion 3101, and one end of the support rod 320 being an insertion end 3201, the insertion end 3201 being suitable for insertion into the insertion portion 3101.

[0055] It should be explained that in this embodiment, the mounting body 310 is configured as the first connecting arm 102a or the second connecting arm 202a in the above embodiment, and the support rod 320 is configured as the front leg rod 210, rear leg rod 220, front seat rod 230, or rear back rod 240.

[0056] Furthermore, a pivot 330 is provided in one of the insertion portion 3101 and insertion end 3201, and a guide groove 340 corresponding to the pivot 330 is provided in the other of the insertion portion 3101 and insertion end 3201, and the pivot 330 is slidably engaged with the guide groove 340, and the insertion direction of the support rod 320 to the insertion portion 3101 coincides with the extending direction of the guide groove 340, and when the insertion end 3201 of the support rod 320 is pulled out from the insertion portion 3101, the support rod 320 The pivot 330 and guide groove 340, which are slidably engaged with each other, can rotate relative to the mounting body 310, thereby forming a folded state, and after the support rod 320 is withdrawn from the mounting body 310, it is converted to the folded state, or in the process of the support rod 320 being gradually converted from the folded state to the unfolded state, and in this process the support rod 320 and the mounting body 310 are always rotatably connected, and in this process the support rod 320 and the mounting body 310 do not separate. Furthermore, when the pivot 330 and the guide groove 340 slide relative to each other, the distance between the insertion end 3201 of the support rod 320 and the insertion portion 3101 of the mounting body 310 changes, thereby facilitating the folding or unfolding of the support rod 320 relative to the mounting body 310. However, if the central axis of the insertion portion 3101 and the central axis of the insertion end 3201 are in the same plane, and the central axis of the insertion portion 3101 and the central axis of the insertion end 3201 create a relative angle, the support rod When the support rod 320 is in a folded state, and the central axis of the insertion portion 3101 and the central axis of the insertion end 3201 are on the same straight line, it is indicated that the support rod 320 is in an unfolded state, and since the central axis of the insertion portion 3101 and the central axis of the insertion end 3201 are on the same plane, when the support rod 320 is converted from a folded state to an unfolded state, the insertion end 3201 and the insertion portion 3101 can be automatically aligned, and the unfolding of the support rod 320 is smooth.

[0057] In this embodiment, the pivot 330 is attached to the insertion portion 3101, the guide groove 340 is installed at the insertion end 3201, one end of the guide groove 340 is the first position limiting end 3401, and the other end is the second position limiting end 3402, the guide groove 340 has a first assembly position and a second assembly position relative to the pivot 330, when the support rod 320 is in the first assembly state (deployed state), the insertion end 3201 is inserted into the insertion portion 3101, the pivot 330 slides to the first assembly position, and at this time the pivot 330 slides to the first position limiting end 3401, When the pivot 330 slides to the second assembly position, the pivot 330 slides against the second position limiting end 3402, the insertion end 3201 can rotate in the first direction relative to the insertion part 3101 via the pivot 330, and the support rod 320 is in the second assembly state (folded state). When the support rod 320 is converted from a folded state to an unfolded state, the insertion end 3201 can rotate in a second direction relative to the insertion portion 3101 via the pivot 330, and the sliding path of the pivot 330 along the guide groove 340 provides a contact guide for inserting the insertion end 3201 into the insertion portion 3101.

[0058] An escape opening 3102 is provided in the insertion portion 3101, and when the support rod 320 is converted from an unfolded state to a folded state, or from a folded state to an unfolded state, the escape opening 3102 provides rotational escape space for the insertion end 3201. Specifically, the insertion portion 3101 has two relief openings 3102, and the two relief openings 3102 have an asymmetrical structure. The depth of the relief opening 3102 closer to the mounting body 310 is greater than the depth of the relief opening further away from the mounting body 310, thereby limiting the first direction to the rotational direction toward the mounting body 310 and the second direction to the rotational direction toward the mounting body 310. After the first direction is limited by the relief opening 3102, when the support rod 320 rotates in the first direction to the second assembled state (folded state), the support rod 320 tends to form a bundle that is in close contact with the surface of the mounting body 310.

[0059] Furthermore, the relief opening 3102, which is deeper on the side closer to the mounting body 310, provides the support rod 320 with a relatively large rotational relief space, resulting in a large folding angle for the support rod. Conversely, when the support rod 320 rotates away from the mounting body 310, the relief opening, which is shallower, does not provide a relatively large relief space, resulting in a relatively small folding angle for the support rod 320. In this way, a poka-yoke effect can be achieved, and the user can intuitively understand that the rotational folding direction of the support rod 320 is toward the mounting body 310. In addition, after the support rod 320 is folded, it adheres closely to the surface of the mounting body 310, forming a bundle. If there are multiple support rods 320, all of them can adhere closely to the surface of the mounting body 310 after being folded. In this way, the volume of the entire structure after folding can be reduced, making it easier to fasten and restrain.

[0060] When the pivot 330 slides to the first position limiting end 3401 of the guide groove 340, the support rod 320 is in the first assembled state, and at this time, the insertion end 3201 of the support rod 320 is inserted into the insertion portion 3101, and the support rod 320 is stopped relative to the insertion portion 3101. Specifically, in this state, the pivot 330 restricts the position of the support rod 320, and when the support rod 320 is subjected to force, it cannot be further inserted into the insertion portion 3101, and at the same time, the support rod 320 cannot rotate relative to the insertion portion 3101, thereby achieving a high-strength support effect after deployment. When the pivot 330 slides to the second position limiting end 3402 of the guide groove 340, the support rod 320 is in a second assembled state, the insertion end 3201 of the support rod 320 is withdrawn from the insertion part 3101, the insertion end 3201 can rotate around the pivot 330 in the relief space provided by the relief opening 3102, the support rod 320 can rotate relative to the mounting body 310, and when the support rod 320 rotates until its circumferential surface contacts the bottom surface of the relief opening 3102, the support rod 320 is in a folded state relative to the mounting body 310.

[0061] Furthermore, in this embodiment, the distance L1 from the center of the pivot 330 to the bottom of the relief opening 3102 is smaller than the length L2 of the guide groove 340. The advantage of this design is that when the insertion end 3201 of the support rod 320 is fully inserted into the insertion portion 3101, the pivot 330 is positioned at the first position limiting end 3401 of the guide groove 340, and when the insertion end 3201 of the support rod 320 is fully withdrawn from the insertion portion 3101, the pivot 330 is positioned at the second position limiting end 3402 of the guide groove 340. When L2 is greater than L1, after the insertion end 3201 of the support rod 320 is completely withdrawn from the insertion portion 3101, the pivot 330 reaches the second position limiting end 3402, and the end face of the insertion end 3201 completely exits the insertion portion 3101 and enters the relief space. At this time, the end face of the insertion end 3201 can be positioned within the space where the relief opening 3102 is located, and in this case, the insertion end 3201 can rotate around the pivot 330 within the space provided by the relief opening 3102.

[0062] Furthermore, in this embodiment, the mounting body 310 has two or more insertion portions 3101, and the number of support rods 320 inserted into the mounting body 310 is two or more, making it easy to insert multiple support rods 320 into the mounting body 310.

[0063] An elastic member 350 is positioned between the support rod 320 and the mounting body 310, and the elastic member 350 is preferably a cable, with one end of the elastic member 350 inserted into and connected to one support rod 320, and the other end of the elastic member 350 inserted into the mounting body 310 and inserted into and connected to another support rod 320, and the elastic member 350 is either a first cable 250 or a second cable 260.

[0064] Specifically, a buckle cover 360 is generally attached to the end of the support rod 320, and the end of the elastic member 350 is inserted into the inside of the support rod 320 and connected to the buckle cover 360. As an example of two support rods 320 that are attached to the mounting body 310, after the elastic member 350 is attached between the two support rods 320, both ends of the elastic member 350 exert a pulling force on the two support rods 320, and when the support rods 320 are not inserted into the mounting body 310, the support rods 320 are also pulled by the elastic member 350, and when the support rods 320 are inserted into the insertion part 3101, the elastic member 350 When the support rod 320 is in a natural or tensile state and is in a rotatably folded state relative to the mounting body 310, the elastic member 350 is in an elastically tensile state. When the support rod 320 is converted from the folded state to the unfolded state, the elastic tensile force of the elastic member 350 causes the insertion end 3201 of the support rod 320 to be automatically inserted into the insertion part 3101. This easy-deployment structure, through the engagement of the pivot 330 and the guide groove 340, and the structural design of the elastic member 350, enables automatic alignment and insertion of the support rod 320 with the insertion part 3101 when the external restraint is released while the support rod 320 is in the folded state.

[0065] In summary, a bendable elastic member 350 is positioned between the support rod 320 and the frame member, and the elastic member 350 is in a state of tensile energy storage when the support rod 320 is folded. When the external restraint is released, the contraction force of the elastic member 350 drives the support rod 320 to rotate around the pivot 330, thereby automatically aligning the central axis of the insertion end 3201 and the central axis of the insertion portion 3101 on the same axis. The axial force of the elastic member 350 drives the pivot 330 to slide along the guide groove 340 from the second position limiting end 3402 to the first position limiting end 3401, thereby inserting the insertion end 3201 into the insertion portion 3101 along the insertion direction.

[0066] The present invention will be described in detail below, along with a specific description of the usage of the easily deployable structure 300.

[0067] The easily deployable structure 300 of this application includes a folded state and an unfolded state. When in the folded state, the support rod 320 is folded relative to the mounting body 310. When in the unfolded state, the support rod 320 is inserted into the insertion portion 3101 of the mounting body 310. For explanation purposes, when the support rod 320 is folded relative to the mounting body 310, the elastic member 350 is in a tensile state, generating a tensile force on the support rod 320. Therefore, a restraining band (not shown) is installed on the mounting body 310 to bundle and fix the support rod 320.

[0068] Specifically, during the process of the easily deployable structure 300 being converted from a folded state to an unfolded state, the support rod 320 rotates around the mounting body 310 to which it is connected, until the insertion end 3201 faces the insertion portion 3101. At this time, the elastic member 350 is in a tensile state, and the support rod 320 is automatically inserted into the insertion portion 3101 by the elastic tensile force of the elastic member 350.

[0069] Furthermore, when the easily deployable structure 300 is in the folded state, the pivot 330 is located at the second position limiting end 3402, and when the easily deployable structure 300 is in the deployed state, the pivot 330 is located at the first position limiting end 3401. When the easily deployable structure 300 is converted from the folded state to the deployed state, the elastic tensile force of the elastic member 350 causes the support rod 320 to rotate around the mounting body 310 on the pivot 330 until the insertion end 3201 of the support rod 320 faces the insertion portion 3101. At the same time, the elastic tensile force of the elastic member 350 causes the insertion end 3201 of the support rod 320 to be inserted into the insertion portion 3101. During this process, the pivot 330 slides relative to the guide groove 340 from the second position limiting end 3402 to the first position limiting end 3401.

[0070] When the easily deployable structure 300 is converted from the deployed state to the folded state, the pivot 330 slides with respect to the guide groove 340 from the first position limiting end 3401 to the second position limiting end 3402, the support rod 320 rotates around the mounting body 310 with the pivot 330 as the axis, the elastic member 350 is in a tensile state, and the relief opening 3102 provides the insertion end 3201 with the relief space necessary for rotation.

[0071] In summary, the easily deployable structure 300 is used at the connection point between the support rod 320 and the mounting body 310, the insertion end 3201 of the support rod 320 and the insertion portion 3101 of the mounting body 310 are rotatably connected by a pivot 330, the insertion end 3201 of the support rod 320 or the insertion portion 3101 of the mounting body 310 is provided with a guide groove 340 that slidably engages with the pivot 330, and the insertion portion 3101 is provided with a relief opening 3102, and support When the rod 320 is withdrawn a certain distance from the insertion portion 3101 and the pivot 330 slides to the second position limiting end 3402 of the guide groove 340, the support rod 320 rotates with respect to the insertion portion 3101 around the pivot 330 and is in a folded state, and the relief opening 3102 provides the insertion end 3201 with the necessary relief space to rotate from within the insertion portion 3101, and the support rod 320 and the insertion portion 3101 are rotatably connected but do not separate. When it is necessary to deploy the support rod 320, the support rod 320 rotates around the pivot 330 in the opposite direction to the insertion portion 3101, and when the insertion end 3201 of the support rod 320 faces the insertion portion 3101, the insertion end 3201 should be inserted into the insertion portion 3101. At this time, the pivot 330 slides to the first position limiting end 3401 of the guide groove 340, and the pivot 330 limits the position of the support rod 320, preventing it from being further inserted into the insertion portion 3101 when force is applied to it. Simultaneously, the support rod 320 rotates relative to the insertion portion 3101. By being immobile, a high-strength support effect is achieved after deployment. After using this easy-deployment structure, during the process of converting the support rod 320 from the folded state to the deployed state, there is no need for manual contact between the insertion end 3201 of the support rod 320 and the insertion portion 3101 of the mounting body 310. Due to the engagement between the pivot 330 and the guide groove 340, after the support rod 320 is deployed, its insertion end 3201 can automatically align with the insertion portion 3101, making assembly between the support rod 320 and the mounting body 310 convenient and efficient. Furthermore, an elastic member 350 is positioned between the support rod 320 and the mounting body 310. When the support rod 320 is in a folded state, the elastic member 350 is in a tensile state. When the support rod 320 is converted from a folded state to an unfolded state, the elastic tensile force of the elastic member 350 automatically inserts the insertion end 3201 of the support rod 320 into the insertion part 3101. This easy-deployment structure, through the engagement of the pivot 330 and the guide groove 340, and the structural design of the elastic member 350, enables automatic alignment and insertion of the support rod 320 with the insertion part 3101 when the external restraint is released while the support rod 320 is in a folded state.

[0072] During the folding process of the entire folding chair, the ends of the first rotating arm 102 and the second rotating arm 202 are each grasped by one hand of the human body, ensuring uniform force distribution and smooth folding. Furthermore, the front leg rod 210, rear leg rod 220, front seat rod 230, and rear back rod 240, which are movably attached to the first rotating arm 102 and the second rotating arm 202, are also easy to fold. When each rod returns to its original position, it can automatically align and be automatically inserted, making operation convenient and quick.

[0073] Example 4 Referring to Figures 28 to 29, and based on a similar technical concept, an embodiment of the present application provides and explains a folding chair 200 (in this embodiment, the seat pocket is not shown) that includes the rotating folding structure 100 in Embodiment 1 or Embodiment 2. In the drawing of the folding chair 200 of this embodiment, only the rotating folding structure 100 in Embodiment 1 is shown. After the folding chair 200 adopts the above folding structure 100, the entire folding chair 200, when folding and unfolding, has ends of the first rotating arm 102 and the second rotating arm 202 each grasped by one hand of the human body, the receiving force is uniform, and folding is smooth.

[0074] Furthermore, in this embodiment, the front leg rod 210, rear leg rod 220, front seat rod 230, and rear back rod 240 of the first rotating arm 102 are all connected via the easy-to-deploy structure 300, and similarly, the front leg rod 210, rear leg rod 220, front seat rod 230, and rear back rod 240 of the second rotating arm 202 are all connected via the easy-to-deploy structure 300.

[0075] Referring to Figures 30 to 34, the difference between this embodiment and Embodiment 3 is that the easily deployable structure 300 in this embodiment and the easily deployable structure in Embodiment 3 differ in their structural design. The design difference of the easily deployable structure 300 in this embodiment is that an insertion opening 3103 is provided in the insertion portion 3101, a support guide portion 3400 is provided on the side surface of the insertion portion 3101, and a sliding guide portion 3202 corresponding to the support guide portion 3400 is provided in the insertion end 3201.

[0076] The support rod 320 has a first assembly state and a second assembly state relative to the mounting body 310. When the support rod 320 is converted from the second assembly state to the first assembly state, the sliding guide portion 3202 slides along the support guide portion 3400 due to the action of the tensile force of the elastic member 350, thereby guiding the insertion end 3201 to align with the insertion opening 3103 and insert it.

[0077] Specifically, when the support rod 320 is in the first assembly state, the support rod 320 is in an extended state relative to the mounting body 310, and when the support rod 320 is in the second assembly state, the support rod 320 is in a folded state relative to the mounting body 310.

[0078] Furthermore, when the support rod 320 is folded relative to the mounting body 310, the elastic member 350 is in a tensile state, and when the support rod 320 is subjected to a binding restraint force, it maintains the folded state, and when the binding restraint force is removed, the elastic member 350 drives the support rod 320 to reverse, and after the insertion end 3201 is aligned with the insertion opening 3103 and inserted, the support rod 320 is in an unfolded state relative to the mounting body 310.

[0079] Furthermore, referring to Figure 31, a guide groove 3104 is provided in the insertion portion 3101, one end of the guide groove 3104 is in communication with the insertion opening 3103, and when the support rod 320 rotates relative to the insertion portion 3101, the elastic member 350 can be driven to be introduced into or led out of the guide groove 3104.

[0080] The support guide portion 3400 is provided on the insertion portion 3101 and faces one side of the mounting body 310. When the support rod is converted from an extended state to a folded state, the support rod 320 tends to adhere closely to the surface of the mounting body 310 to form a compact folded state. Since the guide groove 3104 is installed on the support guide portion 3400, whether the support rod 320 is extended or folded, it drives the elastic member 350 to enter or exit the guide groove 3104, thus providing a poka-yoke effect. The user controls the rotational folding method of the support rod 320. It is intuitively understandable that the direction is toward the mounting body 310, and after the support rod 320 is folded, it adheres closely to the surface of the mounting body 310 to form a bundle. In this embodiment, if there are two or more insertion portions 3101 in the mounting body 310, and two or more support rods 320 are inserted into the mounting body 310, and there are multiple support rods 320, then all of the multiple support rods 320 can adhere closely to the surface of the mounting body 310 after being folded. In this way, the volume of the entire structure after folding can be reduced, and binding and restraint can be facilitated.

[0081] Furthermore, the support guide section 3400 includes a flat guide step 3400a and an arc-shaped guide step 3400b, the arc-shaped guide step 3400b being connected to the insertion opening 3103, and the surface of the sliding guide section 3202 being an arc-shaped surface, and when the support rod 320 is converted from a folded state to an unfolded state, the elastic member 350 drives the insertion end 3201 to pass through the flat guide step 3400a and the arc-shaped guide step 3400b in sequence, the insertion end 3201 reverses along the trajectory of the arc-shaped guide step 3400b and is inserted into the insertion opening 3103, thereby achieving automatic alignment and insertion of the support rod 320 and the insertion part 3101 of the mounting body 310, making the assembly between each support rod 320 and the mounting body 310 convenient and efficient.

[0082] Furthermore, the elastic member 350 is preferably an elastic cable, with one end of the elastic member 350 inserted into and connected to one support rod 320, and the other end of the elastic member 350 inserted into the mounting body 310 and also inserted into and connected to another support rod 320.

[0083] In this embodiment, referring to Figures 32 and 33, the easy-to-deploy structure 300 includes a folded state and an unfolded state. When the insertion end 3201 is inserted into the insertion portion 3101, the support rod 320 is stopped against the insertion portion 3101, and at this time, the easy-to-deploy structure 300 is in the unfolded state. When the insertion end 3201 is withdrawn from the insertion portion 3101, the support rod 320 can rotate relative to the insertion portion 3101, at which time the easily deployable structure 300 is in a folded state, and simultaneously the elastic member 350 is in a tensile state. Specifically, when the easily deployable structure 300 is converted from the deployed state to the folded state, the insertion end 3201 is withdrawn from the insertion part 3101, and then the support rod 320 is rotated so that the support rod 320 is in the folded state, the elastic member 350 is introduced into the guide groove 3104, and at the same time the elastic member 350 is in a tensile state. When the easily deployable structure 300 is converted from a folded state to an unfolded state, the tensile force of the elastic member 350 causes the support rod 320 to rotate toward the mounting body 310, and the sliding guide portion 3202 at the end of the support rod 320 slides against the support guide portion 3400 until the insertion end 3201 of the support rod 320 is inserted into the insertion portion 3101. When the support rod 320 is fully unfolded, the support guide portion 3400 includes a flat guide step 3400a and an arc-shaped guide step 3400b, and the arc-shaped guide step 3400b is connected to the insertion opening 3103. Therefore, during the unfolding process, the sliding guide portion 3202 at the end of the support rod 320 sequentially contacts the flat guide step 3400a and the arc-shaped guide step 3400b, allowing the arc-shaped guide step 3400b to smoothly and continuously introduce the sliding guide portion 3202 into the insertion opening 3103.

[0084] To ensure the stability and strength of the support after deployment of the support rod 320, a position-restricting step portion 3105 is provided on the inner wall of the insertion opening 3103, as shown in Figure 34. When the insertion end 3201 of the support rod 320 is inserted into the insertion portion 3101, the position-restricting step portion 3105 restricts the position of the support rod 320 relative to its insertion stroke. When the support rod 320 receives pressure or a supporting force, the support rod 320, after being restricted in position by the position-restricting step portion 3105, cannot be further inserted into the insertion portion 3101. The support rod 320 stably supports the insertion portion 3101, but it can be pulled out.

[0085] In summary, the easy-to-deploy structure 300 is used at the connection point between the support rod 320 and the mounting body 310. Under normal circumstances, the insertion end 3201 of the support rod 320 is inserted into the insertion portion 3101 of the mounting body 310, and the support rod 320 is stopped relative to the insertion portion 3101. At this time, the easy-to-deploy structure 300 is in the deployed state. When the easy-to-deploy structure 300 is folded, the insertion end 3201 of the support rod 320 is pulled out from the insertion portion 3101, and the support rod 320 can rotate relative to the insertion portion 3101. The elastic member 350 is smoothly introduced from the insertion opening 3103 into the guide groove 3104 and is in a tensile state. When the easy-to-deploy structure 300 is converted from the folded state to the deployed state, the elastic member 350 returns to its original position, and due to the tensile force of the elastic member 350, the insertion end 3201 of the support rod 320 is pulled out from the insertion portion 3101. Until it is inserted into the insertion opening 3103 of 101, the sliding guide portion 3202 at the end of the support rod 320 contacts the support guide portion 3400 on the side of the mounting body 310 and slides against the support guide portion 3400, thereby enabling the support rod 320 to return to its original position. After using this easy-deployment structure, in the process of converting the support rod 320 from the folded state to the unfolded state, there is no need for the insertion end 3201 of the support rod 320 and the insertion portion 3101 of the mounting body 310 to come into contact manually. Due to the tensile force of the elastic member 350, the sliding engagement between the sliding guide portion 3202 and the support guide portion 3400 allows the insertion end 3201 to automatically align with the insertion portion 3101 after the support rod 320 has been unfolded, making assembly between the support rod 320 and the mounting body 310 convenient and efficient.

[0086] Furthermore, when the support rod 320 is converted from a folded state to an unfolded state, the elastic member 350 moves from the guide groove 3104 into the insertion opening 3103 and returns to its original position. The guide groove 3104 acts as a return guide for the elastic member 350, ensuring the stability of the elastic member 350 in the direction of tensile force. When the support rod 320 comes into contact with the insertion part 3101, the contact of the support rod 320 is accurate and stable.

[0087] Example 5 Referring to Figures 35 and 36, and based on a similar technical concept, an embodiment of the present application provides a storage box support frame 400 comprising the rotating folding structure 100 in Embodiment 1 or Embodiment 2, support legs 410 inserted into the first rotating arm 102 and the second rotating arm 202, respectively, and support blocks 420 installed on the surfaces of the first rotating arm 102 and the second rotating arm 202, wherein the support legs 410 are connected to the first rotating arm 102 and the second rotating arm 202 via the easily deployable structure 300 shown in Embodiment 3. The storage box support frame 400, when in use, has a support block 420 on which the storage box 430 is placed, and the surface of the support block 420 has a friction surface 440, which can act as an anti-slip surface when the storage box 430 is placed.

[0088] The storage box support frame 400 can be folded and unfolded during use. It should be noted that the drawings of the storage box support frame 400 in this embodiment only show the rotating folding structure 100 in Embodiment 1. Since the first rotating arm 102 and the second rotating arm 202 adopt the design of the rotating folding structure 100, when the storage box support frame 400 is stored and unfolded, the ends of the first rotating arm 102 and the second rotating arm 202 are each grasped by one hand of the human body, the receiving force is uniform, folding is smooth, the support legs 410 are foldable, and when the external restraint is released, the support legs 410 can automatically align with and automatically insert into the insertion parts of the first rotating arm 102 and the second rotating arm 202.

[0089] Example 6 Referring to Figures 37 and 38, and based on a similar technical concept, an embodiment of the present application provides a storage box support frame 400 comprising the rotating folding structure 100 in Embodiment 1 or Embodiment 2, support legs 410 inserted into the first rotating arm 102 and the second rotating arm 202, respectively, and support blocks 420 installed on the surfaces of the first rotating arm 102 and the second rotating arm 202, wherein the support legs 410 are connected to the first rotating arm 102 and the second rotating arm 202 via the easily deployable structure 300 shown in Embodiment 4. The storage box support frame 400 is designed so that when storing and unfolding, the ends of the first rotating arm 102 and the second rotating arm 202 are each grasped by one hand of the human body, the receiving force is uniform, folding is smooth, the support legs 410 are foldable, and when the external restraint is released, the support legs 410 can automatically align with and automatically insert into the insertion points of the first rotating arm 102 and the second rotating arm 202.

[0090] Example 7 Referring to Figures 39 and 40, and based on a similar technical concept, embodiments of the present application provide a table 500 comprising the rotating folding structure 100 in Embodiment 1 or Embodiment 2, lower support legs 510 and upper support rods 520 inserted into the first rotating arm 102 and the second rotating arm 202, respectively, a support assembly 530 connected to the upper support rods 520, and a table plate unit 540 positioned above the support assembly 530. For the purposes of this embodiment, only the rotating folding structure 100 in Embodiment 1 is shown in the drawings of the table 500.

[0091] In this embodiment, the support assembly 530 is An insertion joint 5301 that can be inserted into the end of the upper support rod 520, A lower engagement plate 5302 is attached to one end of the insertion joint 5301, The system includes a table plate support rod 5303 that engages with and connects to a lower engagement plate 5302.

[0092] Furthermore, an upper engagement plate 550 is provided at the bottom of the table plate unit 540. When assembling the table, the lower support legs 510 and upper support rods 520 are inserted into the first and second rotating arms 102 and 202, respectively. An insertion joint 5301 is inserted into the end of the upper support rod 520. The table plate support rod 5303 is engaged and connected to the lower engagement plate 5302 on the insertion joint 5301. The table plate support rod 5303 supports the bottom of the table plate unit 540, and the upper engagement plate 550 at the bottom of the table plate unit 540 is engaged and connected to the table plate support rod 5303.

[0093] The table 500 consists of a removable table plate unit 540, a support assembly 530, a folding structure 100, lower support legs 510 and upper support rods 520. The folding structure 100 constitutes the main support frame of the table, and when folding and unfolding the folding structure 100, the ends of the first rotating arm 102 and the second rotating arm 202 are each grasped by one hand of the human body, the force received is uniform, and folding is smooth.

[0094] Example 8 Referring to Figures 41 to 50, and based on a similar technical concept, an embodiment of the present application provides a table 600 that includes the rotating folding structure 100 of Embodiment 1 or Embodiment 2 and a folding table plate 700 laid on top of the rotating folding structure 100, the drawings of which show the rotating folding structure 100 of Embodiment 1 (of which the lock assembly 30 is not assembled).

[0095] In the rotating folding structure 100, the first connecting arm 102a and the second connecting arm 202a are each fitted with an upper support arm 610 and a lower support arm 620. The upper support arm 610 and the lower support arm 620 are connected to the first connecting arm 102a and the second connecting arm 202a using the easy-deployment structure 300 shown in Embodiment 3 or Embodiment 4. The drawing in this embodiment shows the easy-deployment structure 300 as in Embodiment 3. One end of the upper support arm 610 is connected to an interlocking member 630, and unit beams 6201 and 6202 are slidably attached to the interlocking member 630, that is, the unit beams 6201 and 6202 are slidable relative to the interlocking member 630. In addition, the interlocking member 630 also maintains a relative rotational connection with the upper support arm 610.

[0096] Referring to the unfolded state shown in Figure 41, unit beam 6201 and unit beam 6202 are fitted together to form support beam 6200, both ends of support beam 6200 are attached to interlocking member 630, and connected to upper support arm 610 via interlocking member 630, thereby constructing a support platform for supporting external members at the top of the rotating folding structure 100 via support beam 620. In actual use, the external component may be a tabletop, a storage box, or other article that can be installed between the two horizontal bars.

[0097] Of these, unit beams 6201 and 6202 in the deployed state shown in Figure 41 can be separated when an external operating force is applied, and the separated unit beams 6201 and 6202 are as shown in Figure 42.

[0098] An external operating force is then applied to fold the unit beams 6201 and 6202, which have been separated by the operation, to rotate and move closer to each other. Specifically, as shown in Figure 43, the two unit beams 6201 and 6202, now in close proximity to each other, drive the interlocking member 630 in a sequential manner, causing the interlocking member 630 to rotate relative to the upper support arm 610. This further drives the rotating folding structure 100 to rotate and fold. The state after rotation and folding is as shown in Figure 44.

[0099] Simply put, during the folding operation, an external force causes the two fitted unit beams 6201 and 6202 to slide in opposite directions along the interlocking member 630, separating them and bringing them closer together. The two unit beams 6201 and 6202, now in close proximity to each other, drive the interlocking member 630 in the same direction, causing the interlocking member 630 to rotate relative to the upper support arm 610, and further driving the rotating folding structure 100 to rotate and fold.

[0100] In the rotatable folding state, unit beams 6201 and 6202 are located on the back side of the upper support arm 610, and are close to their respective upper support arms 610, forming a compact folded form. Furthermore, the hinge arm 6302 of the interlocking member 630 has a relief groove 6302a, and the geometry of the relief groove 6302a (e.g., arc-shaped recessed groove, U-shaped notch) matches the upper support arm 610, so that the upper support arm 610 fits into the relief groove 6302a in the rotatable folding state. As a result, unit beams 6201 and 6202 are close to their respective upper support arms 610, forming an even more compact folded form. At this time, it is relatively preferable that the central axes of unit beams 6201 and 6202 are parallel to the central axis of the upper support arm 610.

[0101] Furthermore, the upper support arm 610 can be reversed and folded into the base of the main support frame.

[0102] At this time, referring to Figure 45, the unit beams 6201 and 6202 adjacent to the upper support arm 610 can be reversed and folded together with the upper support arm 610 to the base of the rotating folding structure 100.

[0103] Furthermore, the lower support arm 620 of the rotating folding structure 100 can also be reversed and folded into the base of the rotating folding structure 100.

[0104] At this time, referring to Figure 45, the lower support arm 620 is inverted and folded into the base of the rotating folding structure 100, and at the same time, the unit beams 6201 and 6202 are inverted and folded into the base of the rotating folding structure 100 together with the upper support arm 610, forming a bundled folded state (shown in Figure 46), in which state they can be bundled and fixed using an external restraint band, such as a restraint cord.

[0105] Continuing to refer to Figures 41 to 45, a first elastic member 660 is further provided within the support beam 6200, with one end of the first elastic member 660 connected to one unit beam 6201 of the support beam 6200 and the other end connected to another unit beam 6202. The first elastic member 660 is suitable for applying a tensile force that causes the two unit beams 6201 and 6202 to abut against each other. When the ends of the two unit beams 6201 and 6202 abut, the tensile force from the first elastic member 660 allows the two unit beams 6201 and 6202 to be quickly fitted together. In this embodiment, the first elastic member 660 can be implemented as an elastic rope.

[0106] During the deployment process, when the ends of unit beams 6201 and 6202 are brought close together artificially, the first elastic member 660 provides a sustained contact tensile force, quickly fitting and locking them together without precise adjustment, forming the support beam 6200 (state shown in Figure 41). This significantly improves deployment efficiency, avoids the cumbersome manual alignment and insertion operations, and during folding, the user must apply an external force to overcome the tensile force of the first elastic member 660 in order to separate unit beams 6201 and 6202 (state shown in Figure 42).

[0107] Referring further to Figures 41, 42, and 47, the interlocking member 630 includes a hinge arm 6302 and a sleeve 6301 fixedly connected to the hinge arm 6302. The hinge arm 6302 is movably connected to the upper support arm 610. For example, the hinge arm 6302 is movably hinged to the upper support arm 610, and the sleeve 6301 is slidably fitted onto the outer circumference of the unit beams 6201 and 6202.

[0108] Furthermore, position-restricting end members 670 are fixedly attached to the ends of the unit beams 6201 and 6202, respectively. A position-restricting groove 6701 is provided on one of the position-restricting end members 670 and the sleeve 6301, and a position-restricting projection 6304 that fits into the position-restricting groove 6701 is provided on the other. Specifically, the position-restricting groove 6701 is installed on the position-restricting end member 670, and the position-restricting projection 6304 is installed on the sleeve 6301. After the two unit beams 6201 and 6202 come into contact to form a support beam 6200, the position-restricting end member 670 approaches the sleeve 6301, and the unit The unit beams 6201 and 6202 and the sleeve 6301 are engaged and restricted in position by the position-restricting groove 6701 and the position-restricting projection 6304, and the assembled support beam 6200 is circumferentially restricted in position by the sleeve 6301 so as not to rotate within the sleeve 6301. When the two unit beams 6201 and 6202 are separated, the unit beams 6201 and 6202 slide within the sleeve 6301, and the position-restricting end members 670 at the ends of the unit beams 6201 and 6202 move away from the sleeve 6301, releasing the circumferential position restriction of the unit beams 6201 and 6202 by the sleeve 6301.

[0109] Furthermore, the interlocking member 630 further includes a connecting cap 6303, of which the connecting cap 6303 is movably connected to the upper support arm 610 and can rotate around the upper support arm 610, and the hinge arm 6302 is movably hinged to the connecting cap 6303, and the connecting cap 6303 provides an additional degree of rotational freedom.

[0110] As can be understood, when manipulating the two unit beams 6201 and 6202 to move closer together, it is difficult for the applied force to achieve a "perfect" rotational force. In actual operation, several "distorted" or "inclined" lateral forces may be present, and when these "distorted forces" (lateral components) are present in the movement of the unit beams 6201 and 6202 to move closer together, the connecting cap 6303 can rotate slightly in accordance with these "distorted forces," thereby making the overall folding operation smoother.

[0111] Thus, the hinge arm 6302 provides the rotational freedom of the unit beams 6201 and 6202, and the connecting cap 6303 provides the rotational freedom of the upper support arm 610 around its axis, and together they constitute a universal movable mechanism.

[0112] As can be seen from this, it is more preferable for the interlocking member 630 to hold a universal movable connection with the upper support arm 610, and it will be seen by those skilled in the art that the universal movable mechanism is not limited to the combination structure of the hinge arm 6302 and the connecting cap 6303 exemplified in this embodiment, and may be replaced with other universal movable mechanism methods, such as replacing the connecting cap 6303 with a ball joint socket, replacing the end of the hinge arm 6302 with a ball head, or connecting the hinge arm 6302 to the connecting cap 6303 via a cross axis.

[0113] Furthermore, with respect to the rotating folding structure 100, referring to Figure 41, the base of the rotating folding structure 100 includes a first frame member 10 and a second frame member 20 rotatably connected to the first frame member 10. That is, the first frame member 10 and the second frame member 20 are rotatable relative to each other, and when folding, the two unit beams 6201 and 6202, which are close to each other, can be driven to rotate relative to the first frame member 10 and the second frame member 20 in a sequential manner to fold.

[0114] Specifically, referring to Figure 43, interlocking members 630 are connected to both ends of the first frame member 10 and the second frame member 20, unit beam 6201 is connected to the interlocking member 630 located at the end of the second frame member 20, and unit beam 6202 is connected to the interlocking member 630 located at the end of the first frame member 10, and the folding direction of unit beam 6201 and unit beam 6202 is the same as the folding direction of the first frame member 10 and the second frame member 20.

[0115] Specifically, one interlocking member 630 is connected to each end of the first frame member 10, and a unit beam 6202 is slidably attached to each interlocking member 630. Similarly, one interlocking member 630 is connected to each end of the second frame member 20, and a unit beam 6201 is slidably attached to each interlocking member 630. When a user applies an external force, the separated unit beams 6201 and 6202 are brought closer together, and the adjacent unit beams 6201 and 6202 drive the interlocking members 630 to which they are connected.

[0116] The proximity movement of the unit beam 6201 drives the interlocking member 630 at the end of the second frame member 20 to rotate, and drives the second frame member 20 to rotate, The proximity movement of the unit beam 6202 drives the interlocking member 630 at the end of the first frame member 10 to rotate, thereby driving the first frame member 10 to rotate.

[0117] In this way, the user can synchronously drive the folding of the entire main support frame by simply completing one action: bringing the unit beams closer together.

[0118] When the rotating folding structure 100 is deployed, the multiple upper support arms 610 form support at the bottom of the support platform, and the multiple lower support arms 620 form support on the ground.

[0119] Correspondingly, referring to Figures 48 to 50, when unfolding the table 600, first, the rotating folding structure 100 is unfolded according to the method in the above embodiment, there is a locking groove 710 at the bottom of the folding table 700, and a locking block 6602 at the top of the support head 660a of the folding structure 100, and after unfolding the folding structure 100, the unit beams 6201 and 6202 fit together to form an integrated rigid support beam 6200, and both ends of the support beam 6200 are By being connected to the upper support arm 610 via the interlocking member 630, a support platform is formed at the top of the folding structure 100. When the folding table plate 700 is laid on top of the support beam 6200, the locking block 6602 at the end of the support beam 6200 engages with the locking groove 710 at the bottom of the folding table plate 700, allowing the unfolded folding table plate 700 to be stably supported by the folding structure 100 at the bottom.

[0120] Finally, it should be noted that the above embodiments are used solely to illustrate the technical concepts of the present invention and are not intended to limit them. While the present invention has been described in detail with reference to the embodiments described above, those skilled in the art should understand that they may still modify the technical concepts described in the embodiments above, or make equivalent substitutions for some or all of the technical features thereof, and that such modifications or substitutions will not cause the essence of the corresponding technical concepts to deviate from the scope of the technical concepts of the embodiments of the present invention.
