Description

Technical Field

[0001] The utility model generally relates to the technical field of desks, and particularly to a support connection structure of a table. Background Art

[0002] As is well known, in aspects such as life, work, and study, people are inseparable from desks. The support function is the most basic function of desks. Therefore, table tops, table legs, and frames have become important components of desks. For some existing desks, the frame is designed as a relatively simple "I"-shaped structure, including table leg connecting beams on both sides for connecting table legs and a cross beam connecting the two table leg connecting beams. While ensuring the support effect of the frame, fewer rods are used, saving manufacturing costs.

[0003] For example, the existing patent provides a table frame (Application No.: CN200820303443.8). Each two table legs are connected into a group of table leg frames through a table leg beam, and the table leg beam is connected to at least one cross beam through a connecting wing. The structure is simple and cost-saving, and the cross beam and the table leg beam are detachably connected through the connecting wing, making the assembly of the table frame convenient.

[0004] However, the above solutions have the following problems: Both the table leg beam and the cross beam are tubular or solid rod-shaped structures made of metal, resulting in relatively high costs for manufacturing the table leg beam and the cross beam. And, in order to ensure the stability of the desk, additional table corner connectors need to be processed and set on the front and back sides of the table leg beam to assist in supporting the table top, making the processing and manufacturing operations of the table frame relatively inconvenient. Summary of the Invention

[0005] In view of the above defects or deficiencies in the prior art, it is desirable to provide a support connection structure for a table. Both the table leg connecting beam and the cross beam are made of sheet metal parts, so that the overall manufacturing cost of the frame is relatively low. And, only a first reinforcing member is provided on the table legs at the corner parts of the frame, and the table leg support beam and the cross beam are connected through the first reinforcing member, without additionally processing and setting reinforcing members for auxiliary support on the table leg connecting beam and the cross beam, thus making the processing and manufacturing operations of the frame relatively simple.

[0006] The effect of the present utility model is achieved as follows:

[0007] The present application provides a support connection structure for a table, including a square frame and four table legs arranged diagonally along the frame. The frame includes table leg connecting beams connected between two symmetrically arranged front and rear table legs and a cross beam vertically connected between the two table leg connecting beams. Both the table leg connecting beam and the cross beam are sheet metal parts. A first reinforcing member is provided at the end part of the top of the table leg. The first reinforcing member is configured to connect adjacent table leg connecting beams and the cross beam, and both the table leg connecting beam and the cross beam are detachably connected to the first reinforcing member.

[0008] Furthermore, the first reinforcing member is an angle iron structure, including a first vertical portion arranged vertically and a first horizontal portion bent horizontally from the top end of the first vertical portion. Both the first vertical portion and the first horizontal portion are attached to the inner edges of the table leg connecting beam and the cross beam. This not only further reduces the manufacturing cost of the support connection structure, but also enables the first reinforcing member to fit the inner edges of the two side table leg connecting beams and the cross beam, thus ensuring the connection strength among the three members.

[0009] Furthermore, a number of connection holes are provided on both the first vertical portion and the first horizontal portion. The first reinforcing member is threadedly connected to the table leg connecting beam and the cross beam through the connection holes. This not only ensures the connection strength among the three members, but also makes the installation and disassembly operations among them relatively simple.

[0010] Furthermore, the frame further includes a number of auxiliary support beams vertically arranged between the two cross beams. The auxiliary support beams are also sheet metal parts, and plate-shaped second reinforcing members are horizontally arranged at the front and rear ends of the auxiliary support beams. The auxiliary support beams are detachably arranged on the cross beams through the second reinforcing members. By also setting the auxiliary support beams as sheet metal parts, the manufacturing cost of the tableware is further reduced; and the front and rear ends of the auxiliary support beams are detachably arranged on the cross beams through the second reinforcing members, which not only ensures the connection strength between the auxiliary support beams and the cross beams, but also further improves the simplicity of the frame processing and manufacturing.

[0011] Furthermore, the cross beam is a split structure, including a number of connecting rods spliced end to end along the length direction. The second reinforcing member fits the splicing part of two adjacent connecting rods and connects the two connecting rods. This enables the cross beam to be disassembled to save space and facilitate packaging and transportation, and the size of the frame can be adjusted by adding or reducing the auxiliary support beams and connecting rods between the frames, thus making the processing and manufacturing of the tableware relatively convenient.

[0012] Furthermore, the second reinforcing member is also an angle iron structure, including a second horizontal portion extending horizontally at the top and a second vertical portion perpendicular to the second horizontal portion. The second horizontal portion and the second vertical portion fit the inner edge of the cross beam. This not only further reduces the manufacturing cost of the support connection structure, but also enables the second reinforcing member to fit the inner edge of the cross beam, thus ensuring the connection strength between the two.

[0013] Furthermore, a number of legs are supported at the bottom of the auxiliary support beam. A third reinforcing member is arranged at the end position of the top of the leg. The third reinforcing member includes a connecting portion connected to the end of the top of the leg and reinforcing arms extending from the connecting portion to both sides. The reinforcing arms are beside the end of the top of the leg, and the reinforcing arms are located outside the auxiliary support beam. The reinforcing arms are configured to jointly support the tabletop with the auxiliary support beam. This effectively improves the anti-torsion performance of the auxiliary support beam, making it not easy to bend even if the auxiliary support beam is a sheet metal part. This not only reduces the manufacturing cost of the tableware, but also makes the tableware not easy to shake left and right and have good stability.

[0014] Further, the connecting part and the auxiliary support beam are connected through a positioning structure. The positioning structure includes a positioning groove, which is opened at the upper end of the connecting part and / or the lower end of the auxiliary support beam. The connecting part is clamped to the auxiliary support beam through the positioning groove. The clamping fit between the connecting part and the auxiliary support beam through the positioning groove makes the installation and positioning operation of the third reinforcing member relatively simple.

[0015] Further, the reinforcing arm is an angle iron structure, including a third vertical part extending outward from the connecting part and a third horizontal part bent horizontally from the top end of the third vertical part. The third horizontal part is flush with the top surface of the auxiliary support beam. This not only further reduces the manufacturing cost of the support connection structure, but also enables the second reinforcing member to fit the inner edge of the cross beam, thus ensuring the connection strength between the two.

[0016] Further, along the horizontal direction, there is a gap between the front and rear legs located on the front and rear sides and the front and rear ends of the auxiliary support beam. After the tableware is assembled, the legs are hidden inside the tableware and are not easily exposed. Only the four legs on the bottom of the tableware are easily visible, making the tableware more concise and beautiful in appearance.

[0017] For the support connection structure of the table provided in this application, by setting the frame as a square structure and using sheet metal parts for both the leg connecting beam and the cross beam, the cost required for the overall manufacturing of the frame is relatively low; and the adjacent leg connecting beam and cross beam are connected through the first reinforcing member on the leg, improving the connection strength between the leg connecting beam and the cross beam and ensuring the stability of the tableware; moreover, only the first reinforcing member is provided on the legs located at the corner parts of the frame, without the need to additionally process and set reinforcing members for auxiliary support on the leg connecting beam and the cross beam, thus making the processing and manufacturing operation of the frame relatively simple.

Detailed implementation manners

[0030] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0031] Please refer to the attached Figures 1-10, an embodiment of the present application provides a support connection structure for a table, including a square frame 1 and four table legs 2 arranged diagonally along the frame 1. The frame 1 includes a table leg connection beam 110 connected between two symmetrically arranged front and rear table legs 2 and a cross beam 120 vertically connected between the two table leg connection beams 110. Both the table leg connection beam 110 and the cross beam 120 are sheet metal parts; a first reinforcing member 210 is provided at the end part of the top of the table leg 2, and the first reinforcing member 210 is configured to connect the adjacent table leg connection beam 110 and the cross beam 120, and both the table leg connection beam 110 and the cross beam 120 are detachably connected to the first reinforcing member 210.

[0032] In this embodiment, by setting the frame 1 as a square structure and both the table leg connection beam 110 and the cross beam 120 being made of sheet metal parts, the overall manufacturing cost of the frame is relatively low; and the adjacent table leg connection beam 110 and the cross beam 120 are connected through the first reinforcing member 210 on the table leg 2, which improves the connection strength between the table leg connection beam 110 and the cross beam 120 and ensures the stability of the tableware; moreover, only the first reinforcing member 210 is provided on the table legs at the corner parts of the frame 1, and there is no need to additionally process and set reinforcing members for auxiliary support on the table leg connection beam 110 and the cross beam 120, so that the processing and manufacturing operation of the frame 1 is relatively simple.

[0033] Among them, the first reinforcing member 210 is fixed to the table leg 2 by welding to ensure the connection strength between the two.

[0034] Please refer to the appendix Figures 4-5 , in some embodiments of the present application, the first reinforcing member 210 is an angle iron structure, including a first vertical part 211 arranged vertically and a first horizontal part 212 bent horizontally from the top end of the first vertical part 211. Both the first vertical part 211 and the first horizontal part 212 are attached to the inner edges of the table leg connection beam 110 and the cross beam 120.

[0035] In this embodiment, by setting the first reinforcing member 210 as an angle iron structure with a simple structure, not only the manufacturing cost of the support connection structure is further reduced, but also the first reinforcing member 210 can be attached to the inner edges of the two side table leg connection beams 110 and the cross beam 120, thus ensuring the connection strength among the three.

[0036] Of course, in other embodiments of the present application, the first reinforcing member 210 can also be a block structure, a plate structure, etc.

[0037] Please refer to the appendix Figures 4-5 , in some embodiments of the present application, a plurality of connection holes 213 are formed on both the first vertical part 211 and the first horizontal part 212, and the first reinforcing member 210 is threadedly connected to the table leg connection beam 110 and the cross beam 120 through the connection holes 213.

[0038] In this embodiment, the first reinforcing member 210, the table leg connecting beam 110, and the cross beam 120 are fixed by means of threaded connection, which not only ensures the connection strength among the three, but also makes the installation and disassembly operations among the three relatively simple.

[0039] Please refer to the attached Figure 9 , in some embodiments of the present application, the frame 1 further includes a plurality of auxiliary support beams 130 vertically arranged between the two cross beams 120. The auxiliary support beams 130 are also sheet metal parts, and plate-shaped second reinforcing members 220 are horizontally arranged at the front and rear ends of the auxiliary support beams 130. The auxiliary support beams 130 are detachably arranged on the cross beams 120 through the second reinforcing members 220.

[0040] In this embodiment, when the frame 1 is applicable to table furniture with a relatively large desktop space such as a combined table or a desk, the required size of the frame 1 is relatively large, that is, the length of the cross beam 120 is relatively long, which causes the cross beam 120 to be prone to bending when pressed. In order to ensure the strength of the frame 1, it is necessary to additionally arrange auxiliary support beams 130 inside the frame 1 to support the table board 4. By also setting the auxiliary support beams 130 as sheet metal parts, the manufacturing cost of the table furniture is further reduced; and the front and rear ends of the auxiliary support beams 130 are detachably arranged on the cross beams 120 through the second reinforcing members 220, which not only ensures the connection strength between the auxiliary support beams 130 and the cross beams 120, but also further improves the simplicity of processing and manufacturing of the frame 1.

[0041] Please refer to the attached Figure 9 , in some embodiments of the present application, the cross beam 120 is a split structure, including a plurality of connecting rods 121 spliced end to end along the length direction. The second reinforcing member 220 fits on the splicing part of two adjacent connecting rods 121 and connects the two connecting rods 121.

[0042] In this embodiment, by setting the cross beam 120 as a split structure and connecting two adjacent connecting rods 121 through the second reinforcing members 220 at the front and rear ends of the auxiliary support beam 130, the cross beam 120 can be disassembled to save space and facilitate packaging and transportation. And, as shown in the attached Figure 10 , the size of the frame 1 can be adjusted by adding or reducing the auxiliary support beams 130 and the connecting rods 121 between the frames 1, so that merchants do not need to prepare multiple sets of molds for customers with different requirements, and thus the processing and manufacturing of the table furniture are relatively convenient.

[0043] Please refer to the attached Figure 9 , in some embodiments of the present application, the second reinforcing member 220 is also an angle iron structure, including a second horizontal portion 221 extending horizontally along the top and a second vertical portion 222 perpendicular to the second horizontal portion 221. The second horizontal portion 221 and the second vertical portion 222 fit on the inner edge of the cross beam 120.

[0044] In this embodiment, by also setting the second reinforcing member 220 as a simple angle iron structure, not only the manufacturing cost of the support connection structure is further reduced, but also the second reinforcing member 220 can fit along the inner edge of the cross beam 120, thereby ensuring the connection strength between the two.

[0045] Preferably, the second horizontal portion 221 and the second vertical portion 222 are fixed to the cross beam 120 by means of screw connection. While ensuring the connection strength between the second reinforcing member 220 and the cross beam 120, the installation and disassembly operations between the two are relatively simple.

[0046] Please refer to the appendix Figure 6 , in some embodiments of the present application, several legs 3 are supported at the bottom of the auxiliary support beam 130. A third reinforcing member 310 is provided at the end position of the top of the leg 3. The third reinforcing member 310 includes a connecting portion 311 connected to the end of the top of the leg 3 and reinforcing arms 312 extending from the connecting portion 311 to both sides. The reinforcing arms 312 are beside the end of the top of the leg 3, and the reinforcing arms 312 are located outside the auxiliary support beam 130. The reinforcing arms 312 are configured to support the tabletop 4 together with the auxiliary support beam 130.

[0047] In this embodiment, by providing the third reinforcing member 310 at the end of the top of the leg 3, the reinforcing arms 312 on both sides of the third reinforcing member 310 are located outside the auxiliary support beam 130 and support the tabletop 3 together with the auxiliary support beam 130; when the tableware is subjected to a horizontal force, a torque is generated between the leg 3 and the auxiliary support beam 130, and the torque received by the auxiliary support beam 130 will be shared by the reinforcing arms 312 on both sides, thereby effectively improving the anti-torque performance of the auxiliary support beam 130, so that even if the auxiliary support beam 130 is a sheet metal part, it is not easy to bend, not only reducing the manufacturing cost of the tableware, but also making the tableware not easy to shake left and right and having good stability.

[0048] Preferably, please refer to the appendix Figures 7-8 , two front and rear legs 3 are provided at the bottom of each auxiliary support beam 130, and a storage box 320 is provided between the two legs 3. The storage box 320 is a hollow box-shaped structure, and a wire passing port 321 is provided in a hollowed-out manner at the top end of the storage box 320, so that the cables under the table can be received into the storage box 320 from the wire passing port 321, improving the neatness of the tableware.

[0049] Preferably, please refer to the appendix Figures 7-8, the storage box 320 is of a split structure, including two U-shaped first shielding plates 322 and second shielding plates 323 that are spliced left and right. The first shielding plate 322 is detachably fixed to the legs 3 on both sides by screw connection, and the first shielding plate 322 and the second shielding plate 323 are connected by a clamping structure, including a clamping groove 324 opened on the first shielding plate 322 and a clamping head 325 provided on the second shielding plate 323. When installing the storage box 320, first screw the left and right side walls of the first shielding plate 322 to the legs 3 on both sides through the connection holes, and then align the clamping head 325 of the second shielding plate 323 with the clamping groove 324 on the first shielding plate 322 and snap it in, so that the second shielding plate 323 and the first shielding plate 322 are fixed, thereby realizing the installation of the storage box 320 between the two legs 3. Thus, the installation and disassembly operations of the storage box 320 are relatively simple.

[0050] Please refer to the appendix Figure 6 , in some embodiments of the present application, the connecting portion 311 and the auxiliary support beam 130 are connected by a positioning structure. The positioning structure includes a positioning groove 131, and the positioning groove 131 is opened at the upper end of the connecting portion 311 and / or the lower end of the auxiliary support beam 130. The connecting portion 311 is clamped to the auxiliary support beam 130 through the positioning groove 131. The connecting portion 311 is clamped and matched with the auxiliary support beam 130 through the positioning groove 131, making the installation and positioning operations of the third reinforcing member 310 relatively simple.

[0051] Among them, preferably, positioning grooves 131 are opened at both the third reinforcing member 310 and the lower end of the auxiliary support beam 130, thereby effectively reducing the influence of grooving on the strength of the third reinforcing member 310 and the auxiliary support beam 130.

[0052] Please refer to the appendix Figure 6 , in some embodiments of the present application, the reinforcing arm 312 is of an angle iron structure, including a third vertical portion 313 extending outward from the connecting portion 311 and a third horizontal portion 314 bent horizontally from the top end of the third vertical portion 313. The third horizontal portion 314 is flush with the top surface of the auxiliary support beam 130.

[0053] In this embodiment, by also setting the second reinforcing member 220 to a simple angle iron structure, not only is the manufacturing cost of the support connection structure further reduced, but also the second reinforcing member 220 can fit the inner edge of the cross beam 120, thereby ensuring the connection strength between the two.

[0054] Please refer to the appendix Figures 1-2 , in some embodiments of the present application, along the horizontal direction, there is a gap between the legs 3 located at the front and rear sides and the front and rear ends of the auxiliary support beam 130, so that after the tableware is assembled, the legs 3 are hidden inside the tableware and are not easily exposed. Only the table legs 2 on the four sides at the bottom of the tableware are easily visible, making the tableware more concise and beautiful in appearance.
