Description

Technical Field

[0001] This application relates to the technical field of tables, and more specifically, to a foldable table frame and a table thereof. Background Technology

[0002] Tables are a commonly used structure for placing items, generally consisting of a tabletop and supporting legs located beneath it. Existing structures often involve directly fixing the supporting legs to the tabletop, or assembling them using screws or other connectors. These structures present several problems: First, fixed connections take up a lot of space and are inconvenient to move. Second, while screws allow for assembly before use, once assembled, the tabletop is a fixed structure. Disassembly is required when not in use or for transport, making storage difficult and requiring significant space before disassembly. Utility Model Content

[0003] This application addresses the aforementioned shortcomings of the prior art by providing a foldable table frame that can be quickly folded and unfolded, is easy and quick to operate, and can be flexibly adjusted according to different scenarios.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a foldable table frame, the structure of which includes a main beam, and a movable beam is provided on each side of the main beam along its width direction. The movable beams are rotatably connected to the main beam through a swivel joint, and the movable beams can be folded or unfolded relative to the main beam through the swivel joint. Both ends of the main beam and the free ends of the movable beams are connected to legs. When the movable beams are unfolded relative to the main beam, a tabletop is provided on the main beam and the movable beams. When the movable beams are folded relative to the main beam, the tabletop is detached from the main beam and the movable beams.

[0005] Using the above structure, this application achieves the unfolding and folding of the entire table frame through two movable beams that can rotate relative to the main beam. When the movable beams are unfolded relative to the main beam, the main beam, movable beams, and the legs located at their ends form a complete table frame. At this time, the tabletop can be placed on the unfolded table frame to achieve the assembly and use of the entire table. When not in use, the tabletop is removed from the table frame, and the two movable beams on both sides of the main beam in the width direction are rotated towards the main beam through the swivel joints to achieve the folding of the entire table frame, thereby effectively saving space and facilitating transportation. The above-mentioned structure of this application is very convenient to operate for both unfolding and folding. It does not require disassembling screws or exerting force. It is only necessary to open or fold the movable beams on both sides of the main beam in the horizontal width direction. The operation is simple and quick.

[0006] Furthermore, the steering joint includes a connecting block fixedly connected to the main beam and a steering block located at one end of the movable beam. The steering block and the connecting block are rotatably connected. With this structure, the main beam and the movable beam can be connected to each other through the connecting block and the steering block. The movable beam can also rotate relative to the connecting block in the side direction of the main beam to fit closer to or away from the main beam. The folding and unfolding actions can be achieved through the rotation action.

[0007] Furthermore, the extension length of the movable beam is less than the extension length of the main beam. This means that after the movable beam is folded and stored relative to the main beam, the length of the entire table frame will not exceed the length of the main beam, which helps to save space and facilitates transportation.

[0008] Furthermore, the connection points of the steering joint and the main beam are respectively located near the two ends of the main beam, and the movable beam is folded and close to the long side of the main beam divided from the connection point. With this solution, the movable beam can be completely stored within the length range of the main beam and will not protrude beyond the length of the main beam. Moreover, after unfolding, it can be adjusted to a suitable position by rotating a small angle to support the tabletop.

[0009] Furthermore, a pipe foot fixing component is provided between the main beam and the movable beam and the corresponding connecting pipe foot. With this solution, the pipe foot can be indirectly connected to the movable beam or the main beam through the pipe foot fixing component, making it easy to disassemble and replace.

[0010] Furthermore, the aforementioned foot fixing component includes a fixing body, which has an insertion part for inserting into the main beam or movable beam, and a connecting part for connecting to the foot; the fixing body is provided with an insertion post, and the corresponding tabletop is provided with an insertion hole, the insertion post being used for insertion and positioning with the insertion hole; using the above structure, one end of the foot fixing component is connected to the main beam or movable beam respectively by insertion, and the other end is connected to the foot; and the insertion post on its body, when the tabletop is placed, connects and positions the tabletop and table frame by the mutual insertion and connection of the insertion post and the insertion hole, which also makes the unfolded state of the table frame stable.

[0011] Furthermore, the bottom surface of the plug-in part is provided with a connection hole, and the corresponding main beam or movable beam is also provided with a connection hole. The two types of connection holes are connected to each other by a connector. In this way, after the plug-in part is inserted into the main beam or movable beam, the connection between the beam and the pipe foot fixing part is further strengthened by tightening screws or other connectors in the corresponding connection holes.

[0012] Furthermore, the fixing body is in the form of an isosceles triangle, with one vertex of the isosceles triangle located on the foot side. The midpoint of the base of the isosceles triangle corresponds to the main beam or movable beam. The insertion post is located near the midpoint of the base of the isosceles triangle, and at least one first mounting hole is provided on both sides of the insertion post. Correspondingly, the tabletop is provided with second mounting holes on both sides of the insertion hole, which are connected to the first mounting holes. With this solution, the tabletop can be supported by the fixing body in the isosceles triangle structure, and positioned by the insertion post and the insertion hole on the tabletop. Furthermore, the first mounting holes on both sides of the insertion post can be used to securely connect the tabletop to the tabletop, improving the overall strength of the connection between the tabletop and the table frame.

[0013] Furthermore, a first connecting piece and a second connecting piece are fixedly connected to the upper and lower ends of each of the aforementioned pins. The first connecting piece is used to connect with the pin fixing component, and the second connecting piece is used to connect with the adjusting foot. With this structure, a connecting component, such as a screw, is inserted into the insertion hole and screwed to connect to the first connecting piece, thereby realizing the mutual connection between the pin and the pin fixing component. By screwing an adjusting foot, which is threaded to the second connecting piece, onto the lower end of the pin, the height of each pin can be flexibly adjusted individually according to the stability requirements of the tabletop to adapt to different placement environments.

[0014] This application also provides a table that includes the folding table frame described above. The table with this structure can switch between folded and unfolded states. Moreover, the folding process does not require disassembling screws or other connecting structures. Simply remove the tabletop from the table frame and bring the movable beam close to the side of the main beam to achieve the folding action. The folded structure is neat and occupies little space; unfolding is also relatively simple and convenient. Attached Figure Description

[0028] As attached Figure 1-10 As shown, this application discloses a foldable table frame. The table frame structure includes a main beam 1, with a movable beam 2 on each side of the main beam 1 along its width. The movable beams 2 are rotatably connected to the main beam 1 via a steering joint 3. The movable beams 2 can be folded or unfolded relative to the main beam 1 via the steering joint 3. Both ends of the main beam 1 are connected to the free ends (i.e., the ends away from the steering joint 3) of the movable beams 2, each connected to a leg 4. When the movable beams 2 are unfolded relative to the main beam 1, a tabletop 5 is provided on both the main beam 1 and the movable beams 2. When the movable beams 2 are folded relative to the main beam 1, the tabletop 5 is detached from the main beam 1 and the movable beams 2. Specifically, both ends of the main beam 1 are vertically connected to two legs 4, and the ends of the two movable beams 2 away from the steering joint 3 are also vertically connected to a leg 4. Thus, in the unfolded state, see [details omitted]. Figure 1-3 and Figure 5-6 As shown, four table legs support the tabletop 5; at this time, the upper surfaces of the main beam 1 and the movable beam 2 are attached to the lower surface of the tabletop 5 to form a complete table structure; when not in use, the tabletop 5 is removed from the table frame, and then the two movable beams 2 are moved towards the main beam 1 in the middle along the extension direction of the upper surface to achieve... Figure 4 The folded storage state shown is convenient for placement and transportation, and greatly saves space. Moreover, the thickness of the folded structure is only the superposition of three beams, and the structure is more regular.

[0029] Using the above structure, this application achieves the unfolding and folding of the entire table frame through two movable beams that can rotate relative to the main beam. When the movable beams are unfolded relative to the main beam, the main beam, movable beams, and the legs located at their ends form a complete table frame. At this time, the tabletop can be placed on the unfolded table frame to achieve the assembly and use of the entire table. When not in use, the tabletop is removed from the table frame. Then, the two movable beams on both sides of the main beam in the width direction are rotated towards the main beam through the swivel joints to achieve the folding of the entire table frame, thereby effectively saving space and facilitating transportation. The above-mentioned structure of this application is very convenient to operate for both unfolding and folding. It does not require disassembling screws or exerting force. It is only necessary to open or fold the movable beams on both sides of the main beam in the width direction. The operation is simple and quick.

[0030] As attached Figure 10 As shown, the steering joint 3 described in this application includes a connecting block 301 fixedly connected to the main beam 1, and a steering block 302 located at one end of the movable beam 2. The steering block 302 is rotatably connected to the connecting block 301. Specifically, the connecting block 301 is provided with a mounting hole extending along the transverse width direction of the main beam 1, and is fixedly connected to the side wall of the main beam 1 through the mounting hole. The connecting block 301 is provided with extension plates in the upper and lower directions, and the extension plates are provided with shaft holes. Correspondingly, the steering block 302 is also provided with an extension plate and a shaft hole, and then connected... The shaft holes of block 301 and steering block 302 correspond to each other, and a vertically extending rotating shaft is inserted into the shaft hole to realize the rotatable connection between the two. With this structure, the main beam 1 and the movable beam 2 can be rotatably connected to each other through connecting block 301 and steering block 302. Furthermore, the movable beam 2 can be rotated relative to the connecting block 301 on the side of the two sides corresponding to the lateral width direction of the main beam 1 to fit closer to the main beam 1 for storage or to move away from the main beam 1 for unfolding. The folding and unfolding actions can be realized through the rotation action, making the operation more labor-saving and convenient.

[0031] As attached Figure 1-4 As shown, the extension length of the movable beam 2 described in this application is less than the extension length of the main beam 1. Thus, after the movable beam 2 is folded and stored relative to the main beam 1, the length of the entire table frame will not exceed the length of the main beam 1, which can save space and facilitate transportation.

[0032] As attached Figure 1-4As shown, the connection points of the steering joint 3 and the main beam 1 described in this application are respectively close to the two ends of the main beam 1. The movable beam 2 is folded and close to the long side of the main beam 1 divided from the connection point; that is, after the movable beam 2 is folded and close to the main beam, it will not protrude beyond the length of the main beam 1. With this solution, the movable beam 2 can be completely stored within the length range of the main beam 1 and will not protrude beyond the length of the main beam 1. Moreover, after unfolding, it can be rotated at a small angle to adjust to a suitable position to support the tabletop 5.

[0033] As attached Figure 1-4 As shown, a pipe foot fixing member 6 is provided between the main beam 1 and the movable beam 2 and the corresponding connected pipe foot 4, that is, one end of the pipe foot fixing member 6 is connected to the beam, and the other end extends downward and is perpendicularly connected to the pipe foot 4; with this solution, the pipe foot 4 can be indirectly connected to the movable beam 2 or the main beam 1 through the pipe foot fixing member 6, which makes it easy to disassemble and replace each other.

[0034] As attached Figure 7-8 As shown, the pin fixing component 6 described in this application includes a fixing body 601. The fixing body 601 has an insertion part 602 for inserting into the main beam 1 or the movable beam 2, and a connecting part 603 for connecting to the pin 4 (the extension direction of the insertion part 602 can be perpendicular to the extension direction of the connecting part 603). The fixing body 601 is also provided with an insertion post 604, and the corresponding tabletop 5 is provided with an insertion hole 501. The insertion post 604 is used for insertion and positioning with the insertion hole 501. In this application, both ends of the foot fixing member 6 are connected to the corresponding beam or foot 4 by plugging. With the above structure, one end of the foot fixing member 6 is connected to the main beam 1 or the movable beam 2 by plugging, and the other end is connected to the foot 4. A plugging post 604 is also provided on its fixing member body 601. When the table 5 is placed, the table 5 is connected and positioned to the table frame by plugging the plugging post 604 and the plugging hole 501 provided on the table 5. At this time, the unfolded state of the table frame can also be stabilized.

[0035] As attached Figure 3 and Figure 8As shown, the bottom surface of the plug-in part 602 described in this application is provided with a connection hole 7, and the corresponding main beam 1 or movable beam 2 is also provided with a connection hole 7. The two types of connection holes 7 are connected to each other by a connector. That is, after the plug-in part 602 is inserted into the beam (main beam 1 or movable beam 2), the two types of connection holes 7 correspond to each other. After the plug-in part 602 is inserted into the main beam 1 or movable beam 2, the connection between the beam and the foot fixing member 6 is further strengthened by screws or other connectors in the connection hole 7, so that the foot fixing member 6 is not easy to detach from the beam or foot 4. Specifically, at this time, two connection holes can be arranged side by side along the length extension direction of the plug-in part 602 to improve the connection strength.

[0036] As attached Figure 1-2 , Figure 7-8 As shown, the fastener body 601 described in this application has an isosceles triangular structure. One vertex of the isosceles triangle is located on the side of the tube foot 4. The midpoint of the base of the isosceles triangle corresponds to the main beam 1 or the movable beam 2. The insertion post 604 is located near the midpoint of the base of the isosceles triangle, and at least one first mounting hole 605 is provided on both sides of the insertion post 604. Correspondingly, the tabletop 5 has second mounting holes 502 on both sides of the insertion hole 501 that can connect to the first mounting holes 605. Specifically, the tabletop 5 also has first mounting holes 602 connected to the first mounting holes 605. The corresponding second mounting hole 502 is connected to the first mounting hole 605 and the second mounting hole 502 on the tabletop 5 by screws, bolts and other connectors, further strengthening the connection between the tabletop 5 and the table frame. Moreover, this structure can support the tabletop 5 through the isosceles triangular fastener body 601, and the entire table can be inserted and positioned by the insertion post 604 and the insertion hole 501 on the tabletop 5. Furthermore, the first mounting holes 605 on both sides of the insertion post 604 can be used to make the connection between the tabletop 5 and the tabletop 5 more secure, improving the overall strength and stability of the connection between the tabletop 5 and the table frame.

[0037] As attached Figure 7-9As shown, in this application, a first connecting piece 8 and a second connecting piece 9 are fixedly connected to the upper and lower ends of the tube 4, respectively. The first connecting piece 8 is used to connect with the tube 4 fixing member 6, and the second connecting piece 9 is used to connect with the adjusting foot. Specifically, on the side of the first connecting piece 8 near the tube 4 fixing member 6, the connecting part 603 has an axially provided insertion hole 606 communicating with the inner cavity of the tube 4. A screw can be inserted into the insertion hole 606 as a connector and screwed to connect the first connecting piece 8, thereby achieving a fixed connection between the tube 4 and the tube 4. The nut head can abut against the stepped surface of the insertion hole 606; in addition, an adjusting foot can be provided at the lower end of the tube 4 to achieve a screw-on connection between it and the second connecting piece 9. The adjusting foot can be rotated up and down relative to the axial direction of the tube 4, and the height of each tube 4 can be flexibly adjusted individually according to the stability requirements of the tabletop 5 to adapt to different placement environments and maintain the stability of the entire table; at this time, the adjusting foot is a conventional structure for adjusting the height of the tabletop, specifically, it can be a support base with a stud connected to the support base, and the stud is screwed to the second connecting piece 9, and the height position is adjusted by screwing.

[0038] As attached Figure 5-6 As shown, this application also provides a table with the aforementioned folding table frame. The table with this structure can quickly switch between folded and unfolded states. Moreover, when the tabletop 5 is connected to the insertion post 604 through the insertion hole 501, the folding process does not require disassembling screws or other connecting parts. Simply remove the tabletop 5 from the table frame and bring the movable beam 2 close to the side of the main beam 1 to achieve the folding action. The folded structure is neat and occupies little space; unfolding is also relatively simple and convenient.
