Description

Technical Field

[0001] This invention relates to the field of folding table technology, specifically to a folding table with rotatable legs and a folding method. Background Technology

[0002] As a core piece of furniture in various teaching, meeting, and corporate training activities, the training table's spatial adaptability and ease of use directly affect the utilization rate of the training venue and the efficiency of the activities. With the normalization and increasing frequency of training activities, higher requirements are being placed on the folding and storage performance and venue adaptability of training tables.

[0003] Most existing folding tables use an "I"-shaped fixed structure for their legs, or a staggered folding design for the table legs. However, such designs generally have insurmountable flaws. For example, tables with an "I"-shaped base structure cannot have their base positions adjusted after folding, resulting in a large overall volume after folding, occupying a lot of storage space, and increasing transportation costs and handling difficulties. Furthermore, when stacking folded tables, due to the "I"-shaped fixed structure, a staggered stacking method is generally used to keep the "I"-shaped structure of the table legs unchanged, which still results in a large overall volume after stacking, making it impossible to achieve vertically aligned storage and limiting the improvement of storage space utilization. Although some existing folding tables have a certain degree of rotation capability in their bases, they use a simple connection structure with a single pivot, which limits the rotation range and lacks precise guidance and limit design. This not only makes it easy for the bases to jam or shift during rotation, making it difficult to smoothly switch to the preset storage or support position, but also makes it difficult to coordinate with the folding action of the tabletop, still requiring manual assistance to adjust the base angle. Therefore, there is a need for a table with adjustable rotating bases that are linked to the folding action of the tabletop to achieve vertically aligned storage and reduce the overall volume after folding.

[0004] For example, Chinese patent application No. 202020323188.4, published on December 11, 2020, discloses a foldable height-adjustable table, including a tabletop assembly, a support frame, table legs, a drive mechanism, and height-adjustable table legs driven by the drive mechanism. The tabletop assembly includes a first tabletop and a second tabletop. The bottom surface of the first tabletop is fixedly connected to the top of the support frame, and the first tabletop and the second tabletop are rotatably connected. It also includes a locking device for locking the positions of the first and second tabletops in the unfolded state. In the unfolded state, the upper surfaces of the first and second tabletops form a single tabletop surface. The top surface of the table legs is rotatably connected to the lower end of the height-adjustable table legs, and their rotation axis is perpendicular to the top surface of the table legs. This utility model overcomes the problems of inconvenient packaging and troublesome installation for customers in the prior art of height-adjustable tables. By folding the tabletop and rotating the table legs, the area required for packaging the height-adjustable table can be reduced.

[0005] The above-mentioned documents describe a system where the table legs are positioned by engaging spring pins with the connecting cylinder through holes. While the structure is simple, it requires manual operation after the tabletop is folded to make the legs swing. This system cannot fold the legs while the tabletop is folded, and it cannot limit the leg folding after the tabletop is folded. Accidental contact could cause the legs to suddenly unlock, posing a safety hazard. Furthermore, the table legs can only achieve a single folding posture parallel to the support frame, failing to adapt to the flexible adjustment needs of different storage scenarios. Summary of the Invention

[0006] This invention provides a foldable table with rotatable legs and a folding method. The legs are rotatable and adjustable and are linked to the folding action of the tabletop, so as to achieve the purpose of vertically folding and storing the table and reducing the overall volume.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a foldable table with rotatable legs, comprising a support frame and a tabletop, wherein the tabletop is rotatably connected to the support frame via a rotating connector, and supporting table legs are provided on both sides of the support frame. The rotating connector includes a rotating bracket and a rotating plate, wherein the rotating bracket is rotatably connected to the rotating plate and fixedly connected to the support frame, and the support frame is rotatably connected to the supporting table legs. The rotating plate is connected to the supporting table legs via a driving mechanism, wherein the driving mechanism includes a driving arm and a supporting plate, wherein one side of the driving arm is hinged to the rotating plate and the other side of the driving arm is hinged to the supporting plate, and the supporting plate is fixedly connected to the outer wall of the supporting table legs. When the tabletop drives the rotating plate to rotate around the rotating bracket, the rotating plate drives the driving arm and the supporting plate to swing, thereby causing the supporting table legs to rotate relative to the plane of the support frame, thereby realizing the unfolding support or folding storage of the supporting table legs.

[0008] With the above setup, when the table is unfolded and in use, simply flip the tabletop from a vertical position to a horizontal position. The tabletop will rotate around the rotating bracket along with the rotating plate. As the rotating plate rotates, it will pull or push the drive arm. The drive arm swings flexibly through the hinge points at both ends, transmitting the force to the supporting table legs through the support plate. This causes the supporting table legs to rotate around the plane of the support frame, finally rotating to a suitable angle so that the table legs under the two supporting table legs are parallel to each other. When folding for storage, the tabletop is upright, and the rotating plate rotates in the opposite direction. The drive arm also swings in the opposite direction, causing the supporting table legs to rotate around the plane of the support frame to the other side. Finally, the legs are rotated to a suitable angle, so that one side of the two supporting table legs moves closer to each other, while the other side moves away from each other. This allows the supporting table legs to rotate synchronously during the folding process, thus eliminating the need to fold the tabletop first and then the table legs. This makes the operation convenient. At the same time, after folding, the tabletop is connected to the supporting table legs through the drive mechanism, thereby limiting the supporting table legs and tabletop after folding and ensuring stability.

[0009] Furthermore, the support frame includes a support member, a support ring column is provided inside the support member, a support protrusion is provided on the support ring column, and the support table leg includes a support table rod, a support cavity and a support limiting groove are provided inside the support table rod, the support cavity is rotatably connected to the support ring column, and the support limiting groove is matched with the support protrusion.

[0010] The above configuration includes a support cavity inside the support rod of the table legs, which rotates perfectly with the support ring column inside the support frame. This allows the table legs to rotate freely around the support ring column, meeting the turning requirements during unfolding and folding. Simultaneously, the support limiting groove on the support rod matches the support protrusion on the support ring column. When the table legs rotate around the support ring column with the drive mechanism, the support protrusion slides along the groove until it abuts against the groove wall on one side. At this point, the groove wall forms a rigid barrier, restricting the support protrusion from sliding further and thus limiting the maximum rotation angle of the table legs. Similarly, when rotating in the opposite direction, the support protrusion slides to the groove wall on the other side and is also limited.

[0011] Furthermore, the supporting table leg also includes a connecting table leg, the connecting table leg being provided with a connecting table base, the connecting table base being provided with a connecting table hole, the connecting table hole being connected to the supporting table rod through a first locking member.

[0012] The above settings ensure that the first locking component, such as the bolt, provides reliable connection strength, ensuring that the connection between the support table rod and the table leg does not loosen or slip during the process of transmitting power to the drive arm and rotating the table leg.

[0013] Furthermore, the connecting table base is also provided with a connecting protrusion, and the supporting table rod is provided with a supporting groove corresponding to the position of the connecting protrusion, and the supporting groove is matched with the connecting protrusion.

[0014] The above configuration ensures that the connecting protrusion on the table base and the supporting groove on the supporting table rod are precisely matched, and they remain tightly engaged throughout the entire process of the supporting table rod driving the connecting table legs to rotate. When the drive arm drives the supporting table rod to rotate around the support frame, the engaged connecting protrusion and supporting groove form a rigid torque transmission structure, allowing the rotational power of the supporting table rod to be directly and synchronously transmitted to the connecting table legs, avoiding relative slippage or transmission delay, and ensuring that the supporting table rod and the connecting table legs always maintain the same rotation rhythm, accurately completing the unfolding support or folding storage actions.

[0015] Furthermore, the support table rod is also provided with a support plate, and the support plate is provided with a support block. The drive arm includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the rotating plate, the other end of the first connecting rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the support block.

[0016] In addition to the above configuration, a support plate is also fixedly installed on the support table rod. The support plate has a protruding support block, which provides a stable hinge fulcrum for the drive arm. The drive arm adopts a two-section structure consisting of a first link and a second link. One end of the first link is hinged to the rotating plate and can move synchronously with the rotating plate. The other end of the first link is hinged to one end of the second link to form a flexible swinging intermediate node. The other end of the second link is hinged to the support block on the support table rod, so that the rotational power of the rotating plate can be smoothly and accurately transmitted to the support table legs, driving the table legs to rotate smoothly. Furthermore, the stable connection between the support block and the support plate ensures that the force on the drive arm can be evenly distributed on the support table rod.

[0017] Furthermore, the first connecting rod is hinged to the rotating plate and can rotate relative to the rotating plate around the hinge point, and one end of the first connecting rod is hinged to the second connecting rod and can swing around the hinge point as a fulcrum.

[0018] With the above setup, when the user flips the tabletop, the rotating plate fixedly connected to the tabletop will synchronously follow the tabletop and rotate around the rotating bracket connected to the support frame, completing the initial power transmission. When the rotating plate rotates, it will drive the first link hinged to it to move synchronously. The first link swings flexibly around the hinge point, converting the rotational power of the rotating plate into the swinging power of the first link. Since the other end of the first link is hinged to the second link, the swinging of the first link will pull the second link to move synchronously. The first and second links adaptively adjust the angle of the hinge point, cleverly adapting to the position changes during the transmission process. The end of the second link away from the first link is hinged to the support block of the support plate on the support table rod. The swinging power of the second link will be accurately transmitted to the support block, and then transmitted to the entire support table rod through the support plate. Under the action of power, the support table rod rotates smoothly around the support ring column inside the support frame support component, and finally completes the action of unfolding support or folding storage.

[0019] Furthermore, a baffle assembly is provided along the rotating plate on one side of the drive arm. The baffle assembly includes an auxiliary plate and a baffle connector. One end of the baffle connector is hinged to the rotating plate, and the other end of the baffle connector is connected to the auxiliary plate.

[0020] The above configuration, with the auxiliary plate positioned below the tabletop and facing the user, effectively conceals the user's legs and lower body area when seated, preventing direct exposure of the leg contours and providing a more comfortable and dignified experience when using the table. One end of the baffle connector is hinged to the rotating plate, allowing the baffle assembly to move in sync with the tabletop's rotation. When the tabletop is unfolded horizontally, the auxiliary plate is positioned at the optimal concealing position below the tabletop, securely covering the user's leg area. When the tabletop is folded vertically for storage, the auxiliary plate also adjusts its posture synchronously with the rotating plate, allowing it to move closer to the table legs without interfering with the movement of the drive arm, table legs, or other transmission components.

[0021] Furthermore, the baffle assembly also includes a baffle connecting seat, a baffle connecting arm, and a baffle connecting buckle. The baffle connecting seat is connected to the auxiliary plate, one end of the baffle connecting arm is rotatably connected to the baffle connecting seat, the other end of the baffle connecting arm is rotatably connected to the baffle connecting buckle, and the baffle connecting buckle is rotatably connected to the supporting table rod.

[0022] The above setup provides a stable mounting base for the auxiliary plate with the baffle connecting seat. Both ends of the baffle connecting arm are rotatably connected to the baffle connecting seat and the baffle connecting buckle, respectively. The baffle connecting buckle is rotatably connected to the support table rod. When the table is unfolded horizontally, the auxiliary plate is simultaneously in a flat, vertically concealing position under the table, fulfilling the user's need for concealment and keeping the space under the table neat and tidy. When the table is folded vertically for storage, the auxiliary plate adjusts its angle synchronously with the rotation of the rotating plate and the folding of the support table rod, folding smoothly along the direction of the support frame. It always fits the outer side of the table and the support frame without tilting or bulging, making the overall shape of the folded table compact and tidy.

[0023] Furthermore, the baffle connecting buckle is also provided with a baffle protrusion, and the support table rod is provided with a support guide hole, and the baffle protrusion is slidably connected to the support guide hole.

[0024] With the above configuration, when the support table rod rotates around the support ring column driven by the drive arm, the support table rod will have a relative rotational displacement with the baffle protrusion. At this time, the baffle protrusion can slide flexibly along the preset groove of the support guide hole, which will not hinder the rotation of the support table rod, and can limit the sliding trajectory of the protrusion through the groove wall of the support guide hole, thus preventing the baffle connecting buckle from shifting and shaking when it rotates with the support table rod. At the same time, it can ensure that the auxiliary plate always matches the rotation posture of the support table rod during the linkage process.

[0025] Furthermore, the rotating plate is provided with a locking rod and a limiting tongue; the locking rod is provided with a locking tongue, the locking rod is connected to the limiting tongue through a linkage component, the rotating bracket is provided with a limiting groove corresponding to the position of the limiting tongue, the limiting tongue matches the limiting groove, the rotating bracket is provided with a locking groove corresponding to the position of the locking tongue, and the locking tongue matches the locking groove.

[0026] The above setup connects the tabletop to the rotating plate and the support frame to the rotating bracket. When the tabletop is flipped to a horizontal position, the locking tongue on the rotating plate precisely matches the locking groove on the rotating bracket, forming the first rigid lock on the horizontal state of the tabletop, firmly restricting the tabletop's displacement along the rotation direction. Simultaneously, the locking lever, through a linkage component, synchronously drives the limiting tongue to engage with a limiting groove on the rotating bracket, forming a second lock on the horizontal position of the tabletop. The dual locking structures work together to significantly improve the stability and anti-tipping performance of the tabletop when used horizontally, effectively avoiding the safety risks caused by the failure of a single lock. When the locking tongue is moved away from the locking groove and the limiting tongue is moved away from one limiting groove, and the tabletop is then flipped to a vertical folded state, the limiting tongue can continuously match and engage with another limiting groove in the corresponding position, achieving reliable positioning of the vertical tabletop and preventing the tabletop from shifting or loosening when touched by external force or shaken during handling after folding. This balances the locking safety in the use state with the neatness of storage in the folded state. Furthermore, the tabletop folding method is as follows: S1, release the locking constraint between the rotating plate and the rotating bracket, so that the rotating plate can rotate freely relative to the rotating bracket; S2. Flip the tabletop, which is in the horizontal unfolded state, upward to the vertical storage state. The tabletop simultaneously drives the rotating plate to rotate around the rotating bracket. S3. When the rotating plate rotates, it drives the driving arm to swing, and the driving arm transmits power to the supporting table legs through the support plate. S4. Under the action of power, the supporting table legs rotate inward around the plane of the supporting frame until the bottom contact ends of the two supporting table legs present a folded posture with one side approaching each other and the other side moving away from each other. S5. After the tabletop is flipped to the vertical storage position, the rotating plate and the rotating bracket are locked again to keep the tabletop and the supporting table legs in a folded storage state. Tabletop unfolding method: S6, release the locking constraint between the rotating plate and the rotating bracket, allowing the rotating plate to rotate freely relative to the rotating bracket; flip the tabletop, which is in a vertically folded state, to a horizontal direction, and the tabletop simultaneously drives the rotating plate to rotate around the rotating bracket; when the rotating plate rotates, it drives the drive arm to swing, and the drive arm transmits power to the supporting table legs through the support plate; under the action of power, the supporting table legs rotate outward around the plane of the support frame until the bottom contact ends of the two supporting table legs are parallel, forming a stable support structure; relock the rotating plate and the rotating bracket, so that the tabletop remains in a horizontal use state and the supporting table legs remain in an unfolded support state.

[0027] The above setup uses the tabletop flipping as the core trigger for both folding and unfolding. Through the power transmission of the rotating plate and drive arm, the supporting table legs are simultaneously driven to complete the folding or unfolding action. There is no need to adjust the tabletop first and then fold or unfold the table legs separately, nor is any additional tool required. The first and last steps of folding and unfolding are equipped with locking mechanisms. After unfolding, the rotating plate and rotating bracket are locked to firmly fix the tabletop in a horizontal state and the table legs in a supported state. This prevents the tabletop from flipping or the table legs from shifting due to external force during use, improving the stability of the tabletop and its anti-tipping ability. The relocking mechanism after folding can prevent the tabletop from accidentally unfolding during transportation or storage. Attached Figure Description

Detailed Implementation

[0049] like Figures 1-20 As shown, a foldable table with rotatable legs includes a support frame 1 and a tabletop 2. The tabletop 2 is rotatably connected to the support frame 1 via a rotating connector 3. Supporting table legs 5 are provided on both sides of the support frame 1. The rotating connector 3 includes a rotating bracket 32 ​​and a rotating plate 31. The rotating bracket 32 ​​is rotatably connected to the rotating plate 31 and the support frame 1. The support frame 1 is rotatably connected to the supporting table legs 5. The rotating plate 31 is connected to the supporting table legs 5 via a driving mechanism. The driving mechanism includes a driving arm 4. One side of the driving arm 4 is hinged to the rotating plate 31, and the other side of the driving arm 4 is hinged to the supporting table legs 5. When the tabletop 2 drives the rotating plate 31 to rotate around the rotating bracket 32, the rotating plate 31 drives the driving arm 4 to swing, thereby driving the supporting table legs 5 to rotate to one side, realizing the unfolding support or folding storage of the supporting table legs 5.

[0050] like Figures 2-3As shown, the first link 41 is hinged to the rotating plate 31 and can rotate relative to the rotating plate 31 around the hinge point. One end of the first link 41 is hinged to one end of the second link 42 and can swing around the hinge point as a fulcrum. When the user flips the tabletop 2, the rotating plate 31, which is fixedly connected to the tabletop 2, will synchronously follow the tabletop 2 and rotate around the rotating bracket 32 ​​connected to the support frame 1, completing the initial transmission of power. When the rotating plate 31 rotates, it will drive the first link 41, which is hinged to it, to move synchronously. The first link 41 swings flexibly around the hinge point as a fulcrum, converting the rotational power of the rotating plate 31 into the swinging power of the first link 41. Since the other end of the first link 41 is hinged to the second link 42, the swinging of the first link 41 will pull the second link 42 to move synchronously. The first link 41 and the second link 42 are adaptively adjusted through the angle of the hinge node, cleverly adapting to the position changes during the transmission process; the end of the second link 42 away from the first link 41 is hinged to the support block 5121 of the support plate 512 on the support table rod 51, and the swinging power of the second link 42 will be accurately transmitted to the support block 5121, and then transmitted to the entire support table rod 51 through the support plate 512; under the action of power, the support table rod 51 rotates smoothly around the support ring column 11 in the support member of the support frame 1, and finally completes the action of unfolding support or folding storage.

[0051] like Figures 4-5 As shown, the supporting table leg 5 also includes a connecting table leg 52. The connecting table leg 52 is provided with a connecting table base 521, and the connecting table base 521 is provided with a connecting table hole 5211. The connecting table hole 5211 is connected to the supporting table rod 51 through a first locking member. The first locking member, such as a bolt, can provide reliable connection strength, ensuring that the connection between the supporting table rod 51 and the connecting table leg 52 does not loosen or slip during the process of transmitting power to the drive arm 4 and driving the table leg to rotate.

[0052] The connecting table base 521 is also provided with a connecting protrusion 5212, and the supporting table rod 51 is provided with a supporting groove 511 corresponding to the connecting protrusion 5212. The supporting groove 511 is matched with the connecting protrusion 5212. The connecting protrusion 5212 on the connecting table base 521 and the supporting groove 511 on the supporting table rod 51 are precisely matched, and they remain tightly engaged throughout the entire process of the supporting table rod 51 driving the connecting table leg 52 to rotate. When the drive arm 4 drives the supporting table rod 51 to rotate around the support frame 1, the engaged connecting protrusion 5212 and supporting groove 511 form a rigid torque transmission structure, allowing the rotational power of the supporting table rod 51 to be directly and synchronously transmitted to the connecting table leg 52, avoiding relative slippage or transmission delay, and ensuring that the supporting table rod 51 and the connecting table leg 52 always maintain the same rotation rhythm, accurately completing the unfolding support or folding storage action.

[0053] like Figures 6-7As shown, a support plate 512 is also provided on the support table rod 51, and a support block 5121 is provided on the support plate 512. The drive arm 4 includes a first connecting rod 41 and a second connecting rod 42. One end of the first connecting rod 41 is hinged to the rotating plate 31, and the other end of the first connecting rod 41 is hinged to one end of the second connecting rod 42. The other end of the second connecting rod 42 is hinged to the support block 5121. A support plate 512 is also fixedly installed on the support rod 51. A support block 5121 protrudes from the support plate 512, providing a stable hinge fulcrum for the drive arm 4. The drive arm 4 adopts a two-section structure consisting of a first connecting rod 41 and a second connecting rod 42. One end of the first connecting rod 41 is hinged to the rotating plate 31 and can move synchronously with the rotating plate 31. The other end of the first connecting rod 41 is hinged to one end of the second connecting rod 42 to form a flexible swinging intermediate node. The other end of the second connecting rod 42 is hinged to the support block 5121 on the support rod 51, so that the rotational power of the rotating plate 31 can be smoothly and accurately transmitted to the support table legs 5, driving the table legs to rotate smoothly. With the support block 5121 and the support plate 512 firmly connected, it is ensured that the force on the drive arm 4 can be evenly distributed on the support rod 51.

[0054] like Figure 4 and Figure 7 , Figures 8-9 As shown, the support frame 1 includes a support member, a support ring column 11 is provided inside the support member, and a support protrusion 111 is provided on the support ring column 11. The support table leg 5 includes a support table rod 51, a support cavity 514 and a support limiting groove 513 are provided inside the support table rod 51. The support cavity 514 is rotatably connected to the support ring column 11, and the support limiting groove 513 is matched with the support protrusion 111. The support rod 51 of the supporting table leg 5 has a support cavity 514 inside, which is perfectly matched with the support ring column 11 in the support member of the support frame 1. That is, the support cavity 514 can just accommodate the support ring column 11, allowing the supporting table leg 5 to rotate flexibly around the support ring column 11 to meet the turning requirements when unfolding and folding. At the same time, the support limiting groove 513 on the support rod 51 matches the support protrusion 111 on the support ring column 11. When the supporting table leg 5 rotates around the support ring column 11 with the drive mechanism, the support protrusion 111 will slide along the groove cavity of the support limiting groove 513 until it abuts against the groove wall of the support limiting groove 513 on one side. At this time, the groove wall of the support limiting groove 513 will form a rigid block, restricting the support protrusion 111 from continuing to slide, thereby limiting the maximum rotation angle of the supporting table leg 5. Similarly, when rotating in the opposite direction, the support protrusion 111 slides to the groove wall of the support limiting groove 513 on the other side and is also limited.

[0055] like Figure 4 , 10As shown in Figure -13, a baffle assembly 6 is provided along the rotating plate 31 on one side of the drive arm 4. The baffle assembly 6 includes an auxiliary plate 61 and a baffle connector 62. One end of the baffle connector 62 is hinged to the rotating plate 31, and the other end of the baffle connector 62 is connected to the auxiliary plate 61. The auxiliary plate 61 is located below the tabletop 2 and faces the user, effectively covering the user's legs and lower body area when seated, preventing the leg outline from being directly exposed, thus achieving a concealing effect and allowing the user to use the table more comfortably and appropriately. One end of the baffle connector 62 is hinged to the rotating plate 31, allowing the baffle assembly 6 to move synchronously with the flipping action of the tabletop 2. When the tabletop 2 is unfolded horizontally, the auxiliary plate 61 is positioned in the optimal covering position below the tabletop 2, firmly covering the user's leg area. When the tabletop 2 is folded vertically for storage, the auxiliary plate 61 can also adjust its posture synchronously with the rotating plate 31, allowing the auxiliary plate 61 to move closer to the supporting table legs 5 without interfering with the movement of the drive arm 4, supporting table legs 5, or other transmission components.

[0056] See together Figure 13 As shown, the baffle assembly 6 also includes a baffle connecting seat 63, a baffle connecting arm 64 and a baffle connecting buckle. The baffle connecting seat 63 is connected to the auxiliary plate 61. One end of the baffle connecting arm 64 is rotatably connected to the baffle connecting seat 63, and the other end of the baffle connecting arm 64 is rotatably connected to the baffle connecting buckle. The baffle connecting buckle is rotatably connected to the support table rod 51. The baffle connecting seat 63 provides a stable mounting base for the auxiliary plate 61. The two ends of the baffle connecting arm 64 are rotatably connected to the baffle connecting seat 63 and the baffle connecting buckle, respectively. The baffle connecting buckle is rotatably connected to the support table rod 51. When the table 2 is unfolded horizontally for use, the auxiliary plate 61 is simultaneously in a flat vertical covering position, located in the area below the table 2, which meets the user's need for covering up unsightly areas and makes the space under the table look neat and tidy. When the table 2 is folded vertically for storage, the auxiliary plate 61 adjusts its angle synchronously with the rotation of the rotating plate 31 and the retraction of the support table rod 51, and retracts smoothly along the direction of the support frame 1, always fitting the outer side of the table 2 and the support frame 1, without tilting or protruding, making the overall shape of the folded table compact and tidy.

[0057] The baffle connector is also equipped with a baffle protrusion, and the support table rod 51 is equipped with a support guide hole 515. The baffle protrusion is slidably connected to the support guide hole 515. When the support table rod 51 rotates around the support ring column 11 with the drive arm 4, the support table rod 51 will have a relative rotational displacement with the baffle protrusion. At this time, the baffle protrusion can slide flexibly along the preset groove of the support guide hole 515. This will not hinder the rotation of the support table rod 51, and the groove wall of the support guide hole 515 can limit the sliding trajectory of the protrusion, preventing the baffle connector from shifting and shaking when it rotates with the support table rod 51. At the same time, it can ensure that the auxiliary plate 61 always matches the rotation posture of the support table rod 51 during the follow-up linkage process.

[0058] likeFigure 1 , Figures 14-20 As shown, the rotating connector 3 includes a rotating bracket 32 ​​and a rotating plate 31. The rotating bracket 32 ​​is rotatably connected to the rotating plate 31. The rotating plate 31 is provided with a locking rod 33 and a limiting tongue 35. The locking rod 33 is provided with a locking tongue. The locking rod 33 is connected to the limiting tongue 35 through a linkage component. The rotating bracket 32 ​​is provided with limiting grooves 3221 in at least two directions corresponding to the position of the limiting tongue 35. The limiting tongue 35 matches the limiting grooves 3221. The rotating plate 31 is provided with a locking groove corresponding to the position of the locking tongue. The locking tongue matches the locking groove.

[0059] like Figure 1 and Figures 14-20 As shown, the rotating plate 31 has a rotating cavity inside, and a linkage assembly is provided inside the rotating cavity. The linkage assembly includes a linkage rod 34 and a first spring 38. The locking rod 33 passes through the first spring 38. One end of the first spring 38 abuts against the inner wall of the locking bracket, and the other end of the first spring 38 abuts against the locking tongue 333. One side of the locking tongue 333 is connected to one side of the linkage rod 34, and the other side of the linkage rod 34 is connected to the limiting tongue 35. The rotating cavity provides a closed and stable installation space for the linkage components, effectively preventing the linkage rod 34, the first spring 38, and the locking rod 33 from being exposed to dust, external impacts, etc., while making the overall structure more compact and regular. The locking rod 33 passes through the first spring 38. Utilizing the elastic force of the first spring 38, it can provide a continuous elastic pushing force to the locking tongue 333 when the table 2 is switched to the horizontal use position. The locking tongue 333 is continuously engaged with the locking groove 323 of the rotating bracket 32. At the same time, the linkage rod 34 synchronously pushes the limiting tongue 35 into the corresponding limiting groove 3221, and the limiting tongue 35 continues to extend into the limiting groove 3221, ensuring the stable engagement of the double locking structure. During the unlocking and flipping process... Pulling the locking lever 33 overcomes the spring force of the first spring 38, simultaneously causing the locking tongue 333 to disengage from the locking groove 323 and the limiting tongue 35 to exit the limiting groove 3221. Then, when the tabletop 2 is flipped to the vertical folding position, the locking lever 33 is released, and the elastic rebound force of the first spring 38 drives the linkage rod 34 to reset, pulling the limiting tongue 35 to accurately align with the other limiting groove 3221 on the rotating bracket 32 ​​corresponding to the vertical state. The limiting tongue 35 extends into the limiting groove 3221 and, under the continuous preload of the spring, fits tightly against the inner wall of the limiting groove 3221, achieving reliable positioning of the tabletop 2 in the vertical folding state. At the same time, the locking tongue 333 remains in a ready state under the action of the spring, without interfering with the folding positioning, and the positioning effect is good.

[0060] The locking lever 33 includes a locking plate 332 and a locking rod 331. The locking plate 332 is connected to the locking rod 331. One side of the locking plate 332 is located outside the rotating cavity and abuts against the outer wall of the rotating plate 31. The locking rod 331 passes through the first spring 38. The locking plate 332 is exposed on the outer wall of the rotating plate 31, providing the user with a convenient and reasonably force-bearing operating grip point, making it easier and smoother for the user to pull the locking lever 33 to overcome the elastic force of the first spring 38, effectively reducing the difficulty of unlocking. The structure of the locking rod 331 passing through the first spring 38 not only ensures the installation stability of the first spring 38, so that the spring force can act accurately and stably on the locking rod 331 and then be transmitted to the locking tongue 333 and the limiting tongue 35, but also prevents the first spring 38 from shifting or twisting during the extension and retraction process through the guiding effect of the locking rod 331, ensuring the stable performance of the spring elasticity.

[0061] The locking pull plate 332 is provided with a first locking hole 3321, and the locking rod 331 is provided with a second locking hole 3311. A first fastener 37 is inserted through the first locking hole 3321 and the second locking hole 3311. The locking pull plate 332 and the locking rod 331 are fixedly connected by the cooperation of the first locking hole 3321, the second locking hole 3311 and the first fastener 37 (such as a bolt), ensuring that there is no relative displacement when the tensile force is transmitted through the locking pull plate 332.

[0062] The limiting tongue 35 is provided with a first limiting hole 351, and the linkage rod 34 is provided with a second limiting hole 341. A second fastener 36 is provided in the first limiting hole 351 and the second limiting hole 341. The limiting tongue 35 and the linkage rod 34 are fixedly connected by the cooperation of the first limiting hole 351, the second limiting hole 341 and the second fastener 36, such as bolts, to ensure that there is no relative displacement when the tensile force is transmitted through the linkage rod 34.

[0063] The rotating plate 31 is provided with a first rotating cavity 311 and a second rotating cavity 312. The first rotating cavity 311 is provided with a limiting tongue 35. The second rotating cavity 312 is used to accommodate the rotating bracket 32. The rotating bracket 32 ​​includes a rotating shaft 322 and a third rotating cavity 321. The rotating shaft 322 is provided with one or more limiting grooves 3221. The third rotating cavity 321 is used to accommodate the second rotating cavity 312. The first rotating cavity 311 on the rotating plate 31 provides an independent and enclosed installation and movement space for the limiting tongue 35, which can effectively prevent the limiting tongue 35 from interfering with other components during operation. The space inside the first rotating cavity 311 can ensure that the limiting tongue 35 is away from the space required by the limiting groove 3221. The second rotating cavity 312 and the third rotating cavity 321 of the rotating bracket 32 ​​form a nested fit. When the rotating plate 31 drives the table 2 to flip to a horizontal position, the third rotating cavity 321 accurately accommodates the second rotating cavity 312, making the overall structure more compact and regular, and reducing the space occupied. One or more limiting grooves 3221 on the rotating shaft 322 are precisely aligned with the limiting tongue 35 in the first rotating cavity 311. With the guiding effect of the nested cavity, the limiting tongue 35 can quickly be inserted into the corresponding limiting groove 3221 when horizontally locked or vertically positioned, improving the accuracy of locking and positioning.

[0064] A limiting groove 3221 is provided in the horizontal direction of the rotating shaft 322 along the rotation direction of the rotating plate 31, and a limiting groove 3221 is provided in the vertical direction of the rotating shaft 322 along the rotation direction of the rotating plate 31. The limiting groove 3221 in the horizontal direction is precisely matched with the limiting tongue 35. When the table 2 is flipped to the horizontal use position, the limiting tongue 35 can quickly engage in the groove to form a reliable positioning. Together with the locking tongue 333, it forms a double locking, which firmly restricts the flipping displacement of the table 2 in the rotation direction, greatly improving the stability and anti-tipping ability when used horizontally. The limiting groove 3221 in the vertical direction provides a positioning structure for the folded state of the table 2. When the table 2 is flipped to the vertical storage position, the limiting tongue 35 simultaneously engages in the vertical groove, effectively preventing the table 2 from shifting, loosening, or accidentally flipping when touched by external force or shaken during handling after folding.

[0065] The upper part of the locking tongue 333 engages with the lower part of the locking groove 323. This engagement ensures that even under upward impact, the locking tongue 333 and the locking groove 323 can convert the impact force into a clamping force on the engaging surfaces, preventing the locking structure from loosening and ensuring that the tabletop 2 remains stably horizontal.

[0066] The two locking levers 33 are connected by a transmission rod. The connection between the two locking levers 33 via the transmission rod enables synchronous linkage control of the two locking levers 33.

[0067] Folding method of tabletop 2: S1, release the locking constraint between the rotating plate 31 and the rotating bracket 32, so that the rotating plate 31 can rotate freely relative to the rotating bracket 32; S2. Flip the tabletop 2, which is in a horizontal unfolded state, upward to a vertical storage state. Simultaneously, the tabletop 2 drives the rotating plate 31 to rotate around the rotating bracket 32. S3. When the rotating plate 31 rotates, it drives the driving arm 4 to swing, and the driving arm 4 transmits power to the supporting table leg 5 through the support plate 512. S4. Under the action of power, the supporting table legs 5 rotate inward around the plane of the supporting frame 1 until the bottom contact ends of the two supporting table legs 5 are in a folded posture with one side approaching each other and the other side moving away from each other. S5. After the tabletop 2 is flipped to the vertical storage position, the rotating plate 31 and the rotating bracket 32 ​​are locked again, so that the tabletop 2 and the supporting table legs 5 are kept in the folded storage state. Tabletop 2 unfolding method: S6, release the locking constraint between the rotating plate 31 and the rotating bracket 32, so that the rotating plate 31 can rotate freely relative to the rotating bracket 32; flip the tabletop 2, which is in a vertical storage state, to a horizontal direction, and the tabletop 2 simultaneously drives the rotating plate 31 to rotate around the rotating bracket 32; when the rotating plate 31 rotates, it drives the driving arm 4 to swing, and the driving arm 4 transmits power to the supporting table legs 5 through the supporting plate 512; the supporting table legs 5 rotate outward around the plane of the supporting frame 1 under the action of power until the bottom contact ends of the two supporting table legs 5 are parallel, forming a stable support structure; relock the rotating plate 31 and the rotating bracket 32, so that the tabletop 2 remains in a horizontal use state and the supporting table legs 5 remain in an unfolded support state.

[0068] The folding and unfolding processes are triggered by the flipping of the tabletop 2. Through the power transmission of the rotating plate 31 and the drive arm 4, the supporting table legs 5 are simultaneously driven to complete the folding or unfolding action. There is no need to adjust the tabletop 2 first and then fold or unfold the table legs separately, nor is any additional tool required. The first and last steps of folding and unfolding are equipped with locking operations. After unfolding, the rotating plate 31 and the rotating bracket 32 ​​are locked to firmly fix the tabletop 2 in a horizontal state and the table legs in a supported state. This prevents the tabletop 2 from flipping or the table legs from shifting due to external force during use, thereby improving the stability of the tabletop and its anti-tipping ability. After folding, the locking mechanism can prevent the tabletop 2 from accidentally unfolding during transportation or storage. The working principle of this invention is as follows: When the tabletop 2 is unfolded and used, as long as the tabletop 2 is flipped from the vertical state to the horizontal state, the tabletop 2 will rotate around the rotating bracket 32 ​​along with the rotating plate 31. The rotation of the rotating plate 31 will pull or push the drive arm 4. The drive arm 4 swings flexibly through the hinge points at both ends, transmitting force to the supporting table legs 5, causing the supporting table legs 5 to rotate around the support frame 1 to one side, and finally rotate to a suitable angle so that the table legs under the two supporting table legs 5 are parallel to each other. When folded and stored, stand the tabletop 2 upright, and the rotating plate 31 will rotate in the opposite direction. The drive arm 4 will also swing in the opposite direction, causing the supporting table legs 5 to rotate around the support frame 1 to the other side. Finally, rotate to a suitable angle so that the table legs under the two supporting table legs 5 are close to each other on one side and far apart on the other side.

[0069] The tabletop 2 is fixedly connected to the rotating plate 31, and the support frame 1 is connected to the rotating bracket 32. When the tabletop 2 is flipped to the horizontal use position, the locking tongue 333 on the rotating plate 31 is precisely matched with the locking groove 323 of the rotating bracket 32, forming the first rigid lock on the horizontal state of the tabletop 2, firmly restricting the flipping displacement of the tabletop 2 along the rotation direction. At the same time, the locking rod 33 drives the limiting tongue 35 to engage with a limiting groove 3221 of the rotating bracket 32 ​​through the linkage component, forming the second lock on the horizontal position of the tabletop 2. The double locking structure works together to greatly improve the stability and anti-tipping performance of the tabletop 2 when used horizontally, and effectively avoid the safety risks caused by the failure of a single lock. When the locking tongue 333 is moved away from the locking groove 323 and the limiting tongue 35 is moved away from a limiting groove 3221, and then the table 2 is flipped to a vertically folded state, the limiting tongue 35 can continuously match and engage with another limiting groove 3221 in the corresponding position, so as to achieve reliable positioning of the table 2 in the vertical state, preventing the table 2 from shifting or loosening when touched by external force or shaken during handling after folding, thus taking into account both the locking safety in the use state and the storage neatness in the folded state.
