Description

Technical Field

[0001] This utility model relates to tables, and more particularly to a folding table with a panel that can be folded in half. Background Technology

[0002] Tables are essential pieces of furniture in daily life, often used to place various everyday items. Tables typically consist of a tabletop and a support frame to keep the tabletop level, allowing items to be placed securely. Currently, semi-folding tabletops are quite common. These tabletops are symmetrical, increasing the tabletop area when unfolded, and folding so that the backs of the two tabletops meet, forming a square structure. This results in a smaller packaging volume, facilitating transportation and storage.

[0003] The existing folding table structure has the following problems:

[0004] 1. The table frame structure is not sturdy enough. Usually, the lower parts of the front and rear legs of the table frame are connected by a connecting crossbar. The lower end of the diagonal support bar of the existing table frame is fixed on the front and rear legs, and the connection point is located above the connecting crossbar, which makes the center of gravity not stable enough and it is not easy to form a stable triangular support structure.

[0005] 2. The existing front and rear legs use round tubes. When the table is folded, the front and rear legs fold to the back of the tabletop. The back of the tabletop needs to have a clearance groove to allow the legs to pass. The clearance groove needs to match the round tube, which increases the thickness of the tabletop and makes it heavier, thus increasing the packaging volume and making it inconvenient for consumers to carry.

[0006] 3. Existing blow-molded tabletops are formed as a single piece during the blow molding process. The strength and overall structural integrity of the tabletop can be improved through designed recessed shapes and structures. However, eliminating the gap between the two panels remains a technical challenge that engineers in this field are continuously researching and refining. For example, publication numbers CN201403768Y and CN102293518A disclose a panel-to-panel joint structure. This structure uses teeth (preferably trapezoidal teeth) and grooves formed on the opposite sides of the panels. When the two panels are joined, the teeth and grooves interlock. However, this structure primarily addresses the structural strength at the panel joint. While it improves the strength of the joint compared to earlier panels without this design, it doesn't solve the problem of the gap at the joint, especially on the upper surface (the working surface), which affects the flatness and aesthetics of the tabletop. Furthermore, the middle section of the panel joint is the weakest point, so improving the structural strength in this area is also a technical problem that needs to be solved.

[0007] 4. The legs of the folding table are foldable. When folding, the two legs are folded together. Therefore, in order to fix the folded legs and prevent them from coming loose, there are usually fasteners on the bottom of the table to secure the legs. Existing fasteners usually rely on their own elasticity to fix the legs, which is not strong enough and the legs often come loose.

[0008] 5. When using a folding table, the structural strength is weakest at the middle of the panel joint. Therefore, to improve the structural support strength at this point, a diagonal support rod is connected to a connecting crossbar in the folding legs installed at the bottom of the panel. The two ends of the connecting crossbar are respectively mounted on two pivot seats, which are positioned opposite each other at the joint ends of the two panels. The connecting crossbar can improve the structural strength at the panel joint and distribute the force on the panels. However, due to the lack of a supporting structure between the connecting crossbar and the tabletop, the structural strength at the joint seam of the tabletop is not high. Furthermore, the lack of an effective limiting structure on the connecting crossbar causes the diagonal support rod to move left and right, resulting in table wobbling. In addition, existing diagonal support rods all use flat tubes, which have low structural strength, affecting the overall structural stability of the table frame.

[0009] In conclusion, further improvements are needed to the existing folding table structure. Utility Model Content

[0010] The first technical problem to be solved by this utility model is to provide a folding table with a stable table support structure, in light of the above-mentioned existing technology.

[0011] The second technical problem to be solved by this utility model is to provide a folding table that is conducive to reducing the thickness of the tabletop and the volume of packaging, in view of the above-mentioned existing technology.

[0012] The third technical problem to be solved by this utility model is to provide a folding table that can reduce the gap between the tabletops, in light of the existing technology.

[0013] The fourth technical problem to be solved by this utility model is to provide a folding table with a novel and unique edge and high structural strength, in light of the above-mentioned existing technology.

[0014] The fifth technical problem to be solved by this utility model is to provide a folding table that can reduce the gap between the tabletop joints and improve the structural strength and load-bearing capacity of the joints, in light of the above-mentioned existing technology.

[0015] The sixth technical problem to be solved by this utility model is to provide a folding table in which the table support is not easily separated from the tabletop in the folded state, in view of the above-mentioned existing technology.

[0016] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a folding table, comprising two table bodies that can be folded together, each table body having a tabletop and a table support provided at the bottom of the tabletop, the two table supports being connected by a connecting crossbar, characterized in that: the table support includes a front support leg, a rear support leg, and an inclined support rod, the top end of the front support leg being connected to the top end of the rear support rod by an upper crossbar, the lower part of the front support leg being connected to the lower part of the rear support leg by a lower crossbar, the front support leg and the rear support leg being divided into an upper vertical section, an outward expansion section and a lower vertical section from top to bottom, the upper vertical section and the outward expansion section being connected by a first arc section, the outward expansion section and the lower vertical section being connected by a second arc section, the lower crossbar being horizontally arranged, the two ends of the lower crossbar being connected to the first arc section on the corresponding side, and the inclined support rod being connected between the connecting crossbar and the lower crossbar.

[0017] Preferably, both the first arc segment and the second arc segment are circular arc segments.

[0018] The lower crossbar and the diagonal support rod can have various connection structures. Preferably, the lower crossbar is integrally stamped with a connecting buckle. There are two connecting buckles, which are respectively located at the front and rear ends of the lower crossbar. The diagonal support rod includes an upper diagonal tie rod and a figure-eight brace located at the lower end of the upper diagonal tie rod. The upper end of the upper diagonal tie rod is connected to the connecting crossbar, and the lower end of the figure-eight brace is connected to the corresponding connecting buckle.

[0019] To enhance the structural strength of the lower crossbar, strip-shaped ribs are formed on the lower crossbar, and the strip-shaped ribs are arranged along the length of the lower crossbar and located between the two connecting buckles.

[0020] To further enhance the torsional strength of the lower crossbar, both ends of the lower crossbar have bent sections that bend to the same side, and the upper and lower edges of the lower crossbar are provided with rolled edges that turn to the same side. Furthermore, the rolled edges reduce the likelihood of burrs causing injury, making it safer to use.

[0021] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: the front and rear support legs of the folding table are made of D-shaped tubes, and a relief groove adapted to the D-shaped tubes is formed on the back of the tabletop. When the folding table is folded, the flat side of the D-shaped tube is embedded in the relief groove. This design can reduce the thickness of the tabletop, which is beneficial for reducing the packaging volume.

[0022] Further preferably, the angle between the upper vertical segment and the outward expansion segment, and the angle between the outward expansion segment and the lower vertical segment, are both 145° to 155°.

[0023] Further optimization shows that, in the unfolded state of the folding table, the total length of the two joined tabletops is 1800-1830mm, the center distance between the lower ends of the front and rear support legs is 575-595mm, and the center distance between the upper ends of the front and rear support legs is 290-385mm. This configuration results in a more reasonable tabletop length and support leg dimensions.

[0024] To improve the installation firmness of the foot covers, foot covers are installed on the bottom of both the front and rear support feet. Both the front and rear support feet are hollow tubes. Each foot cover has an outer layer and an inner layer, with an annular groove formed between the outer and inner layers. The front and rear support feet are inserted into and locked into the annular groove.

[0025] To prevent the foot covers from easily falling off the support feet, the outer wall surface of the inner layer and / or the inner wall surface of the outer layer are formed with raised ribs for securing the front and rear support feet.

[0026] The technical solution adopted by this utility model to solve the third technical problem mentioned above is as follows: the tabletop has a mating side, and an extension portion that gradually expands outward from bottom to top is integrally provided on the upper part of the mating side, and the upper surface of the extension portion becomes the extension surface of the upper surface of the tabletop extending outward. This design utilizes the plasticity of plastic to make the tabletop seamless at the mating point, resulting in a flatter and more aesthetically pleasing tabletop.

[0027] Further preferably, the extension gradually expands outwards from bottom to top into a slope, with a height of 3-10mm, and the extension surface's extension degree does not exceed 0.5mm. That is, the length of the upper surface of the tabletop extending beyond the mating side should preferably not exceed 0.5mm. If the extension is too long, the deformation will be significant, potentially causing wrinkles and an uneven tabletop. If it is too short, it will not achieve the desired seam-free effect. The height of the extension can be adjusted accordingly based on the tabletop thickness.

[0028] Preferably, the tabletop is a one-piece molded hollow blow-molded board, with spaced grooves and protrusions formed on the lower part of the mating sides. When the two tabletops are joined together, the protrusions are embedded in the corresponding grooves. This design allows the two tabletops to interlock on the lower part of the mating sides using the interlocking protrusions and grooves, improving the seamless joint effect and creating better structural strength. Furthermore, the protrusions and grooves are concealed, preserving the aesthetics of the tabletop.

[0029] The technical solution adopted by this utility model to solve the fourth technical problem mentioned above is as follows: the edge of the folding table, except for the mating side, has a stepped structure. The stepped structure has an upper stepped surface and a lower stepped surface. The height difference between the upper and lower stepped surfaces is 1-3mm, the width of the stepped structure is 5-8mm, the edge radius (R) of the upper stepped surface is 0.5-1.5mm, and the edge radius (R) of the lower stepped surface is 2-4mm. This design makes the edge of the table more novel and unique, and also helps to improve the structural strength of the table edge.

[0030] The technical solution adopted by this utility model to solve the fifth technical problem mentioned above is as follows: The folding table has two interlocking connecting seats installed in the middle of the connecting crossbar. Each connecting seat includes a sleeve portion and a connecting portion extending outward from the upper part of the sleeve portion. The connecting portion is fixed to the back of the tabletop on the corresponding side. The sleeve portion is fitted onto the connecting crossbar, and the inner end of the inclined support rod is rotatably connected to the connecting portion on the corresponding side. This arrangement, through the connection seats, provides stronger support to the tabletop in the weakest middle section, improving the structural strength at this point. Furthermore, the tight interlocking of the two connecting seats ensures a tight seam in the tabletop.

[0031] The connector can have various structures. Preferably, the connecting part includes two adjacent L-shaped connecting blocks. A first mounting hole is formed on the horizontal portion of each L-shaped connecting block. A connector passes through the first mounting hole and is fixed to the back of the tabletop. A slot is formed between the vertical portions of the two L-shaped connecting blocks. The inner end of the inclined support rod is inserted into the slot. A second mounting hole is formed on the vertical portion of the inclined support rod. The connector passes through the second mounting hole and connects to the inner end of the inclined support rod. With this configuration, the inclined support rod is connected to the L-shaped connecting blocks and remains confined within the slot, preventing lateral movement and ensuring good table stability.

[0032] To reliably fix the connector to the tabletop, a recessed mounting portion adapted to the transverse portion is formed at the middle position of the bottom joint of the two tabletops. An embedded part is pre-embedded in the recessed mounting portion, and the transverse portion is fixedly connected to the embedded part via a connector. By using embedded parts, the connection of the connector can be made more secure. Typically, the embedded part can be a nut, and the connector can be a screw.

[0033] Further preferably, at least one sleeve is fitted onto the connecting crossbar on each side of the connecting seat. The sleeve has a connecting piece extending upwards to the top of the connecting crossbar, and the connecting piece is fixed to the bottom of the tabletop. This arrangement further disperses the force on the tabletop joint, distributes the support points, and ensures a reasonable force distribution throughout the joint, guaranteeing the structural strength and stability of the connection device and improving the load-bearing capacity of the tabletop. The connecting piece can have various structures, with an L-shape being preferred. Alternatively, an embedded part can be provided on the back of the tabletop, and the connecting piece can be fixed to the embedded part via the connecting part, ensuring a stable and secure connection.

[0034] The technical solution adopted by this utility model to solve the sixth technical problem mentioned above is as follows: A buckle for fixing the front and rear support legs is also installed at the bottom of the tabletop. The buckle has a C-shaped main body with its opening facing downwards. A snap-fit ​​portion extends from the top of the main body, and the snap-fit ​​portion snaps onto the back of the tabletop. The front and rear support legs are snapped onto the main body. With this configuration, in the folded state, the table support can be fixed to the back of the tabletop by the buckle, preventing it from detaching.

[0035] The buckle can be fixed to the tabletop in various ways. As a preferred solution, the snap-fit ​​part has a first snap-fit ​​foot, a second snap-fit ​​foot, and a limiting protrusion located on three different sides. The limiting protrusion is located between the first snap-fit ​​foot and the second snap-fit ​​foot. Correspondingly, the bottom of the tabletop has a first snap-fit ​​groove, a second snap-fit ​​groove, and a limiting groove. The first snap-fit ​​foot is engaged in the first snap-fit ​​groove, the second snap-fit ​​foot is engaged in the second snap-fit ​​groove, and the limiting protrusion is engaged in the limiting groove. With this design, the snap-fit ​​structure eliminates the need for connectors when connecting to the tabletop, making the snap-fit ​​installation of the folding table simpler and more convenient.

[0036] To ensure the clips are more reliably secured to the tabletop, as another preferred solution, a longitudinal through hole is provided at the bottom of the main body. Correspondingly, a pre-embedded nut is installed on the back of the tabletop at the position corresponding to the longitudinal through hole. A screw passes through the longitudinal through hole and is threaded onto the pre-embedded nut to secure the clips to the tabletop. With this configuration, the clips will not detach from the tabletop unless the screws are removed, resulting in a more robust installation structure.

[0037] In order to fasten the support foot to the buckle, an openable movable buckle is installed at the opening of the main body. One end of the movable buckle is rotatably connected to one side of the opening of the main body, and the other end of the movable buckle is fastened to the other side of the opening of the main body.

[0038] Preferably, the buckle is a one-piece molded plastic part. This design allows the elasticity of the plastic part to reliably hold the support leg in place with the buckle.

[0039] To enhance the structural strength of the tabletop, it is a hollow blow-molded board with contact points distributed on its back. These contact points are X-shaped, Y-shaped, T-shaped, cross-shaped, or straight. Correspondingly, different contact points have different numbers of bows and contacts inside, and the distribution of the bows and contacts also varies.

[0040] Compared with the prior art, the advantages of this utility model are as follows: The front and rear support legs of the folding table are divided into an upper vertical section, an outward expansion section, and a lower vertical section from top to bottom. The upper vertical section and the outward expansion section are connected by a first arc section, and the outward expansion section and the lower vertical section are connected by a second arc section. The two ends of the lower crossbar are connected to the first arc section on the corresponding side, which can enhance the bending strength of the support leg. In addition, the diagonal support rod is connected between the connecting crossbar and the lower crossbar. The lower end of the diagonal support rod is lowered, and the table frame can present a stronger support structure, thereby improving the front and rear stability of the entire table and avoiding swaying. The front and rear support legs adopt D-shaped tubes. When folded, the flat side of the D-shaped tube is embedded in the relief groove on the back of the tabletop, which can reduce the thickness of the tabletop and facilitate the reduction of packaging volume. The tabletop is joined together. The upper side features an integral extension that gradually expands outwards from bottom to top, with the upper surface of the extension becoming an extension of the tabletop's upper surface. The plasticity of the plastic allows for seamless joints, resulting in a flatter and more aesthetically pleasing tabletop. Two interlocking connectors installed in the middle of the connecting crossbar provide strong support to the weakest point of the tabletop, improving structural strength. The tight fit of the two connectors ensures a tight seam in the tabletop. The tabletop's edge features a stepped structure with appropriately chamfered edges on both the upper and lower steps, creating a more novel and unique edge design while enhancing structural strength. Furthermore, when folded, the table frame can be secured to the back of the tabletop with clips to prevent detachment. Attached Figure Description

[0072] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0073] Example 1:

[0074] like Figures 1 to 7As shown, the folding table in this embodiment includes two foldable table bodies 1. Each table body 1 has a tabletop 11 and a table support 12 located at the bottom of the tabletop 11. The two table supports 12 are connected by a connecting crossbar 13. The two ends of the connecting crossbar 13 are connected to two pivot seats 1a respectively. Two frames 1b are connected by the two pivot seats 1a and can be folded around the connecting crossbar 13 to fold the two tabletops 11. The pivot seats 1a and the frames 1b are also part of the table support 12. After folding, a joint 100 is formed between the two tabletops 11. The tabletop 11 is made of a one-piece molded hollow blow-molded board, and the back of the tabletop 11 has contact points 110. The above structure is the conventional structure of existing folding tables, and the specific structure will not be described in detail.

[0075] The table support 12 of this embodiment includes a front support leg 121, a rear support leg 122, an inclined support rod 123, an upper crossbar 124, and a lower crossbar 125. The top end of the front support leg 121 is connected to the top end of the rear support rod through the upper crossbar 124. Both ends of the upper crossbar 124 are connected to the frame 1b. The lower part of the front support leg 121 is connected to the lower part of the rear support leg 122 through the lower crossbar 125.

[0076] like Figure 8 As shown, in this embodiment, the front support leg 121 and the rear support leg 122 are divided into an upper vertical section 12a, an outwardly expanding section 12b, and a lower vertical section 12c from top to bottom. The upper vertical section 12a and the outwardly expanding section 12b are connected by a first arc-shaped section 12d, and the outwardly expanding section 12b and the lower vertical section 12c are connected by a second arc-shaped section 12e. In this embodiment, both the first arc-shaped section 12d and the second arc-shaped section 12e are circular arcs. The included angle between the upper vertical section 12a and the outwardly expanding section 12b, and the included angle between the outwardly expanding section 12b and the lower vertical section 12c, are both 145° to 155°. The lower horizontal bar 125 is horizontally arranged, and its two ends are connected to the first arc-shaped section 12d on the corresponding side, thereby enhancing the bending strength of the support leg. In this embodiment, the inclined support rod 123 is connected between the connecting crossbar 13 and the lower horizontal bar 125. With the lower end of the diagonal support rod 123 lowered, the table frame can present a stronger support structure, thereby improving the overall front-to-back stability of the table and preventing wobbling.

[0077] like Figure 9 and Figure 10As shown, a connecting buckle 1251 is integrally stamped on the lower crossbar 125. There are two connecting buckles 1251, which are respectively located at the front and rear ends of the lower crossbar 125. The connecting buckles 1251 are used to connect the diagonal support rod 123. Specifically, the diagonal support rod 123 includes an upper diagonal tie rod 1231 and a figure-eight brace 1232 located at the lower end of the upper diagonal tie rod 1231. The upper end of the upper diagonal tie rod 1231 is connected to the middle of the connecting crossbar 13, and the lower end of the figure-eight brace 1232 is connected to the corresponding connecting buckle 1251. In this embodiment, the figure-eight brace 1232 is made of elliptical or round tube, which has higher structural strength compared with the flat tubes on the market.

[0078] In this embodiment, a strip-shaped rib 1252 is formed on the lower crossbar 125. The strip-shaped rib 1252 is arranged along the length of the lower crossbar 125 and is located between the two connecting buckles 1251. In addition, both ends of the lower crossbar 125 have bent sections 1253 that bend to the same side, and the upper and lower edges of the lower crossbar 125 are provided with rolled edges 1254 that turn to the same side. The bent sections 1253 can enhance the torsional strength of the lower crossbar 125, and the rolled edges 1254 can prevent burrs from pricking people, making it safer to use.

[0079] The folding table in this embodiment preferably adopts the following dimensions: after the table is unfolded, the overall length of the table, i.e., the sum of the lengths of the two tabletops 11, is between 1800-1830mm, the width of the tabletops 11 is between 680-740mm, the thickness of the tabletops 11 is between 30-40mm, and the overall height of the table support 12 is between 730-750mm.

[0080] In addition, the relationship between the table length and the dimensions of the table frame 12 needs to be limited. When the folding table is in the open state, if the total length of the two tabletops 11 after splicing is 1800-1830mm, then the center distance between the lower ends of the front support leg 121 and the rear support leg 122 is 575-595mm, and the center distance between the upper ends of the front support leg 121 and the rear support leg 122 is 290-385mm. For example, when the table length is 1830mm, the center distance between the upper ends of the front support leg 121 and the rear support leg 122 is 365-385mm; when the table length is 1800mm, the center distance between the upper ends of the front support leg 121 and the rear support leg 122 is 290-310mm.

[0081] like Figure 11 and Figure 12 As shown, the front support leg 121 and the rear support leg 122 are made of D-shaped tubes. A relief groove 111 adapted to the D-shaped tube is formed on the back of the table 11. When the folding table is folded, the flat side 121a of the D-shaped tube is embedded in the relief groove 111. The relief groove 111 can be relatively shallow, thereby reducing the thickness of the table 11 and making it easier to reduce the packaging volume.

[0082] Both the front support leg 121 and the rear support leg 122 are fitted with foot sleeves 14 at their bottoms. In this embodiment, both the front support leg 121 and the rear support leg 122 are hollow tubes. The foot sleeves 14 have a double-layer structure, with an annular groove 143 formed between the outer layer 141 and the inner layer 142. The front support leg 121 and the rear support leg 122 are inserted into and secured within the annular groove 143. In addition, raised ribs 144 are formed on the outer wall of the inner layer 142 and / or the inner wall of the outer layer 141. When the support leg is inserted into the annular groove 143, the raised ribs 144 can engage and secure the front support leg 121 and the rear support leg 122, preventing the foot sleeves 14 from falling off.

[0083] like Figures 13 to 17 As shown, the tabletop 11 in this embodiment has a mating side 112. In a conventional design, the upper surface of the tabletop 11 and the mating side 112 are arranged perpendicularly, and the edge of the upper surface of the tabletop 11 does not extend beyond the mating side 112. In this embodiment, the upper part of the mating side 112 is integrally provided with an extension portion 113 that gradually expands outward from bottom to top, and the upper surface of the extension portion 113 becomes the extension surface of the upper surface of the tabletop 11, which extends outward and slightly exceeds the original mating side 112. The extension portion 113 can be plastically deformed when mated.

[0084] like Figure 17 As shown, the extension 113 is a slope. Depending on the thickness of the tabletop 11, the extension 113 can gradually expand outward from bottom to top from a distance of 3-10mm from the upper surface of the tabletop 11 on the mating side 112, i.e., h2 = 3-10mm. The extension d of the extended surface should be ≤0.5mm, meaning that the length of the upper surface 11 of the tabletop 11 extending beyond the mating side 112 should not exceed 0.5mm. If the extension is too long, the deformation will be large, which may cause wrinkling due to deformation, making the tabletop uneven. If it is too short, it will not achieve the effect of sealing the joint. With this structure, when the two tabletops 11 are joined, the plasticity of the plastic allows the upper surfaces of the two tabletops 11 to be tightly joined at the joint 100 without gaps. See [reference needed]. Figure 1 and Figure 5 This ensures the desktop is flat and aesthetically pleasing.

[0085] like Figure 13 and Figure 14As shown, the tabletop 11 has spaced grooves 114 and protrusions 115 formed on the lower part of the mating side 112. The grooves 114 and protrusions 115 are arranged at intervals along the length of the mating side 112. When the two tabletops 11 are in contact with each other, the protrusions 115 are embedded in the corresponding grooves 114, realizing the interlocking of the mating tabletops 11. In addition, it is also necessary to ensure that the two can rotate relative to each other so that the two tabletops 11 can be folded relative to each other. Generally, it is preferred that the protrusions 115 are designed as trapezoidal shapes with arc surfaces, and the corresponding grooves 114 are designed as grooves with trapezoidal receiving cavities. For example, if the thickness of the protrusion is 5mm, then the depth of the groove can be 6.5mm, so that there is a certain gap between the two.

[0086] When the two tabletops 11 are joined together, the protrusions 115 and grooves 114 between them interlock, preventing the seams on the back of the tabletops 11 from being on a straight line. This ensures the strength of the joint and further reduces the gap 100 at the joint, guaranteeing the flatness of the tabletop. Furthermore, after joining, the protrusions 115 and grooves 114 are completely hidden and not visible from the outside, improving the aesthetics and overall appearance of the tabletop.

[0087] like Figure 15 and Figure 16 As shown, the edge of the tabletop 11, excluding the mating side 112, has a stepped structure. The stepped structure has an upper stepped surface 116 and a lower stepped surface 117. The height difference h1 between the upper stepped surface 116 and the lower stepped surface 117 is 1–3 mm. The width of the stepped structure w is 5–8 mm. The edge radius r1 of the upper stepped surface 116 is 0.5–1.5 mm, and the edge radius r2 of the lower stepped surface 117 is 2–4 mm. See also... Figure 14 As shown, the corners of the tabletop 11 are rounded, and the radius of the corner (R) of the tabletop 11 is R = 50-60mm. The rounded corner structure of the tabletop 11 not only makes the edges of the tabletop more novel and unique, but also helps to improve the structural strength of the tabletop edges.

[0088] like Figure 18 and Figure 19 As shown, two connecting seats 15 that can be mated together are installed in the middle of the connecting crossbar 13. The connecting seats 15 are located in the middle of the width direction of the tabletop 11. The setting of the connecting seats 15 can provide stronger support to the middle part of the folding tabletop where the support strength is weakest, thereby improving the structural strength at this point. In addition, the two connecting seats 15 are tightly mated together, which can make the center seam of the tabletop tight.

[0089] The connecting seat 15 in this embodiment includes a sleeve portion 151 and a connecting portion 152 extending outward from the upper part of the sleeve portion 151. The connecting portion 152 is fixed to the back of the tabletop 11 on the corresponding side, the sleeve portion 151 is sleeved on the connecting crossbar 13, and the inner end of the inclined support rod 123 is rotatably connected to the connecting portion 152 on the corresponding side.

[0090] The connecting portion 152 in this embodiment includes two adjacent L-shaped connecting blocks 1521. Each L-shaped connecting block 1521 has a horizontal portion 1522 and a vertical portion 1524 perpendicular to the horizontal portion 1522. A first mounting hole 1523 is formed on the horizontal portion 1522, and a second mounting hole 1526 is formed on the vertical portion 1524. A slot 1525 is formed between the vertical portions 1524 of the two L-shaped connecting blocks 1521.

[0091] like Figure 14 As shown, a recessed mounting portion 118, adapted to the transverse portion 1522, is formed at the middle position of the bottom joint of the two tabletops 11. An embedded part (not shown in the figure) is pre-embedded in the recessed mounting portion 118. The transverse portion 1522 is fixedly connected to the embedded part via a connector 16. Typically, the embedded part is a pre-embedded nut, and the connector 16 is a screw. The screw passes through the first mounting hole 1523 and is fixed to the pre-embedded nut, thereby fixing the connecting seat 15 to the tabletop 11. The inner end of the inclined support rod 123 is inserted into the slot 1525 and connected to the inner end of the inclined support rod 123 via a connector. The inclined support rod 123 can rotate relative to the connecting seat 15. In this embodiment, the connector is made of plastic, which utilizes the plasticity of plastic to facilitate tightening of the connector without hindering the rotation of the inclined support rod 123.

[0092] like Figure 2 , Figures 5 to 7 As shown, two sleeves 17 are respectively fitted on the connecting crossbar 13 and on both sides of the connecting seat 15. Each sleeve 17 has a connecting piece 171 extending upwards to the top of the connecting crossbar 13, and the connecting piece 171 is fixed to the bottom of the tabletop 11. Various fixing structures can be used between the connecting piece 171 and the tabletop 11; this embodiment uses an L-shape. After installing the sleeves 17 on the connecting crossbar 13, the connecting piece 171 can further disperse the force on the mating part of the tabletop 11, distribute the support points, and ensure a reasonable distribution of force at the entire mating point, thus ensuring the structural strength and stability of the connecting device and improving the load-bearing capacity of the tabletop. Alternatively, a pre-embedded part can be set on the back of the tabletop, with the connecting piece 171 attached to the back of the tabletop 11 and fixed to the pre-embedded part through a connector, ensuring a stable and secure connection of the connecting piece 171. Similarly, the pre-embedded part can be a pre-embedded nut, and the connector can be a screw.

[0093] like Figure 2 and Figure 5As shown, when the folding table is folded, the table support 12 rests against the bottom of the tabletop 11. A buckle 18 is installed at the bottom of the tabletop 11, which secures the front support leg 121 and the rear support leg 122 of the table support 12 to prevent them from coming apart. The specific structure of the buckle 18 is not limited and various different structures can be used.

[0094] like Figure 20 and Figure 21 As shown, the buckle in this embodiment is made of a one-piece molded plastic part, utilizing the elasticity of the plastic itself to secure the support legs. The buckle 18 in this embodiment has a C-shaped main body 181 with its opening facing downwards. A snap-fit ​​portion 182 extends from the top of the main body 181, snapping onto the back of the tabletop 11. The front support leg 121 and the rear support leg 122 are snapped onto the main body 181. Specifically, the snap-fit ​​portion 182 has a first snap leg 1821, a second snap leg 1822, and a limiting protrusion 1823 located on three different sides. The limiting protrusion 1823 is located between the first snap leg 1821 and the second snap leg 1822. Correspondingly, a first slot 1191, a second slot 1192, and a limiting slot 1193 are formed at corresponding positions on the bottom of the tabletop 11. With the tabletop 11 inverted, the buckle 18 is held upside down on the back of the tabletop 11 with its clamp facing upwards. Specifically, the first locking foot 1821 is engaged in the first locking groove 1191, the second locking foot 1822 is engaged in the second locking groove 1192, and the limiting protrusion 1823 is engaged in the limiting groove 1193. The groove walls of the first locking groove 1191 and the second locking groove 1192 protrude outwards to form a protruding part 1194. The protruding part 1194 can be designed as a protruding body with a rounded transition surface, which facilitates the insertion of the buckle 18 and avoids friction.

[0095] like Figure 22 and Figure 23 As shown, an openable movable buckle 184 is installed at the opening of the main body 181. One end of the movable buckle 184 is rotatably connected to one side of the opening of the main body 181, and the other end of the movable buckle 184 is fastened to the other side of the opening of the main body 181. Before the support leg is inserted, the movable buckle 184 is open; after the support leg is inserted, the movable buckle 184 is fastened to prevent the support leg from coming off.

[0096] like Figure 24 and Figure 25 As shown, a longitudinal through hole 183 is opened at the bottom of the main body 181. Correspondingly, a pre-embedded nut 191 is installed on the back of the tabletop 11 at the position corresponding to the longitudinal through hole 183. The screw 192 passes through the longitudinal through hole 183 and is threaded onto the pre-embedded nut 191. With this installation structure, the buckle 18 can be firmly fixed on the tabletop 11. Only by unscrewing the screw 192 can the buckle 18 be removed from the tabletop 11. The structure is very sturdy.

[0097] Example 2:

[0098] like Figure 26 As shown, the contact points 110 in this embodiment include two types: X-shaped and cross-shaped, which are staggered. Both the X-shaped and cross-shaped contact points have four bows 110a and five contacts 110b. The four bows 110a surround one of the contacts 110b, and each of the four bows 110a has a contact 110b on its outer side.

The three bows 110a are Y-shaped and are evenly distributed around one of the contacts 110b. Each of the three bows 110a has a contact 110b on its outer side.

[0105] Example 6:

[0106] like Figure 30 As shown, the contact point 110 in this embodiment is in a straight line shape. The straight-line contact point has two bows 110a and three contacts 110b. The two bows 110a are located on either side of the contact point 110b in the middle position, and each bow 110a has a contact point 110b on its outer side. In this embodiment, the straight-line contact points are distributed in a crisscross pattern to improve the structural strength of the tabletop. For this type of straight-line contact point 110, the number of bows 110a is not limited to two; it can be one or more. Correspondingly, the number of contacts 110b is one more than the number of bows 110a.

[0107] Example 7:

[0108] like Figure 31As shown, the contact points 110 in this embodiment are elliptical or dot-shaped. Each elliptical or dot-shaped contact point has a bow 110a and two contacts 110b, with the two contacts 110b located on either side of the bow 110a. In this embodiment, the elliptical or dot-shaped contact points are distributed in a crisscross pattern to enhance the structural strength of the tabletop.
