Description

Technical Field

[0001] The utility model generally relates to the technical field of desks, and particularly relates to a frame auxiliary support structure and a combined desk. Background Art

[0002] Desks are commonly used furniture in people's daily lives. To adapt to various usage environments, desks have evolved into various different forms and functions. For example, in office spaces, to effectively utilize office space, the tabletop of a desk is usually composed of multiple sub-tabletops spliced together. The frame of the desk usually includes two transverse support beams extending along the length direction of the tabletop and longitudinal support beams vertically arranged on both sides of the two transverse support beams. Since the overall area of the tabletop is relatively large, several auxiliary support beams are usually vertically arranged between the two transverse support beams. The auxiliary support beams support the splicing part of the two sub-tabletops, thereby enhancing the support strength of the two side sub-tabletops and ensuring the stability of the desk.

[0003] For example, a radiation air-conditioning heat exchange device with adjustable tabletop temperature provided in an existing patent (application number: CN202311777457.9) has two transverse support columns between the adjustable frames of the transverse table legs, and a column cross beam connected to the support cross beam is provided between the upper ends of the two transverse support columns. The column cross beam is supported by the transverse support columns, thereby ensuring the strength of the column cross beam; and, vertical baffles are respectively provided on both sides of the transverse support columns. The area enclosed between the transverse support columns and the baffles can be used to store objects such as pipes, improving the practicality of the desk.

[0004] However, the above solutions have the following problems: both the column cross beam and the support cross beam are tubular components, resulting in a relatively high manufacturing cost for the overall frame. If the column cross beam is replaced with a sheet metal part that is easy to manufacture and has a lower cost, due to the poor anti-torsion performance of the sheet metal part, when the desk is subjected to a horizontal force, the transverse support column will apply torque to the column cross beam, and the column cross beam is prone to bending under the action of the torque, which may further cause the desk to shake left and right, resulting in poor stability.

[0005] Therefore, how to ensure the stability of the frame while saving the manufacturing cost of the frame has become the main problem to be solved currently. Summary of the Invention

[0006] In view of the above defects or deficiencies in the prior art, it is desirable to provide a frame auxiliary support structure and a combined table. By providing a first reinforcing member at the top end of the support column, the support arms on both sides of the first reinforcing member are located outside the auxiliary support beam and jointly support the tabletop with the auxiliary support beam; the torque received by the auxiliary support beam is distributed to the support arms on both sides, thereby effectively improving the torque resistance performance of the auxiliary support beam. Even if the auxiliary support beam is a sheet metal part, it is not easy to bend, which not only reduces the manufacturing cost of the tableware, but also makes the tableware not easy to shake left and right and has good stability.

[0007] The effects of the present invention are achieved as follows:

[0008] In a first aspect, the present application provides a frame auxiliary support structure, including:

[0009] A main frame, which includes two parallel transverse support beams and longitudinal support beams provided at both ends of the transverse support beams;

[0010] An auxiliary support assembly, which includes a plurality of auxiliary support beams vertically arranged between the two transverse support beams, and a plurality of support columns supporting the bottom of the auxiliary support beams. The auxiliary support beam is a sheet metal part, the cross-section of the auxiliary support beam is U-shaped and the opening of the auxiliary support beam faces downward. The area surrounded by the middle of the auxiliary support beam forms a first installation groove, and the top of the support column is inserted and positioned in the auxiliary support beam through the first installation groove; a first reinforcing member is provided at the end position of the top of the support column. The first reinforcing member includes a mounting portion connected to the end of the top of the support column and support arms extending from the mounting portion to both sides. The support arms are beside the end of the top of the support column, and the support arms are located outside the auxiliary support beam. The support arms are configured to jointly support the tabletop with the auxiliary support beam.

[0011] Further, the mounting portion 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 mounting portion and / or the lower end of the auxiliary support beam. The mounting portion is clamped to the auxiliary support beam through the positioning groove. The clamping cooperation between the mounting portion and the auxiliary support beam through the positioning groove makes the installation and positioning operation of the first reinforcing member relatively simple.

[0012] Further, the support arm is an angle iron structure, which includes a first vertical portion extending outward from the mounting portion and a first horizontal portion bent horizontally from the top end of the first vertical portion. The first horizontal portion is flush with the top surface of the auxiliary support beam. This not only makes the processing and manufacturing of the support arm relatively simple, but also the support arm has good strength.

[0013] Furthermore, there are two front and rear struts at the bottom of each auxiliary support beam, and a cable management bin is arranged between the two struts. The cable management bin is a hollow box-shaped structure, and the top of the cable management bin is hollowed out with a cable routing opening, which is configured to receive the cables under the table into the cable management bin. This enables the cables under the table to be sorted and stored through the cable management bin, avoiding the accumulation and chaos of the cables under the table, making the tableware cleaner, more beautiful, expanding the functions of the tableware, and enhancing the practicality.

[0014] Furthermore, the cable management bin is a split structure, including a left baffle and a right baffle that are spliced left and right. The left baffle and the right baffle are detachably connected through a clamping component. The clamping component includes a clamping head and a clamping groove. The clamping head is arranged on one of the left baffle and the right baffle, and the clamping groove is arranged on the other of the left baffle and the right baffle. This makes the installation and disassembly operations of the cable management bin relatively simple, thus facilitating packaging and transportation.

[0015] Furthermore, along the horizontal direction, there is a gap between the struts on the front and rear sides and the front and rear ends of the auxiliary support beam. After the tableware is assembled, the struts and the cable management bin are hidden inside the tableware and are not easily exposed, making the tableware more concise and beautiful in appearance.

[0016] Furthermore, both the transverse support beam and the longitudinal support beam are sheet metal parts. Plate-shaped second reinforcing parts are horizontally arranged at the front and rear ends of the auxiliary support beam, and the auxiliary support beam is connected to the transverse support beam through the second reinforcing parts. This further reduces the manufacturing cost of the tableware. Moreover, the auxiliary support beam is connected to the transverse support beam through the second reinforcing parts, thereby enhancing the strength of the transverse support beam and ensuring the stability of the tableware.

[0017] Furthermore, the transverse support beam is a split structure, including several sub-rods spliced end to end along the length direction. The second reinforcing part fits the splicing part of two adjacent sub-rods, and the left and right sides of the second reinforcing part are respectively detachably connected to the two sub-rods. This enables the main frame to be disassembled to save space and facilitate packaging and transportation, and the size of the main frame can be adjusted by adding or reducing auxiliary support beams and sub-rods between the main frames, making the processing and manufacturing of the tableware relatively convenient.

[0018] Furthermore, the second reinforcing part is an angle iron structure, including a second horizontal part extending horizontally at the top and a second vertical part perpendicular to the second horizontal part. The cross-section of the transverse support beam is U-shaped, and the opening side of the transverse support beam faces the auxiliary support beam. The area surrounded by the middle of the transverse support beam forms a second installation groove. The second reinforcing part is snapped into the second installation groove, and the second horizontal part and the second vertical part fit the inner edge of the transverse support beam. This further enhances the connection strength between the second reinforcing part and the transverse support beam.

[0019] In a second aspect, the present application also provides a combined table, which includes a plurality of table boards and a frame auxiliary support structure. A support area is formed between any pair of symmetrically arranged secondary rods in the front-back direction and the auxiliary support beams or longitudinal support beams on their left and right sides. Each support area is connected with a table board, so that a plurality of table boards can be spliced into a whole along the length direction of the main frame. When manufacturing the combined table, only the corresponding number of table boards needs to be selected according to the number of support areas on the main frame and then lapped, thus making the processing and manufacturing operation of the combined table relatively convenient.

[0020] For the frame auxiliary support mechanism and the combined table provided by the present application, by arranging a first strengthening member at the top end of the support column, the support arms on both sides of the first strengthening member are located outside the auxiliary support beam and jointly support the table board with the auxiliary support beam; when the tableware is subjected to a horizontal force, a torque is generated between the support column and the auxiliary support beam, and the torque received by the auxiliary support beam will be shared by the support arms on both sides, thereby effectively improving the torque resistance performance of the auxiliary support beam, making it not easy to bend even if the auxiliary support beam is a sheet metal part, 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.

The support arms 231 are configured to support the table board 3 together with the auxiliary support beam 210.

[0036] In this embodiment, by providing a first reinforcing member 230 at the top end of the support column 220, the support arms 231 on both sides of the first reinforcing member 230 are located outside the auxiliary support beam 210 and jointly support the tabletop 3 with the auxiliary support beam 210; when a horizontal force is applied to the tableware, a torque is generated between the support column 220 and the auxiliary support beam 210, and the torque received by the auxiliary support beam 210 will be distributed to the support arms 231 on both sides, thereby effectively improving the torque resistance performance of the auxiliary support beam 210, so that even if the auxiliary support beam 210 is a sheet metal part, it is not easy to bend, which not only reduces the manufacturing cost of the tableware, but also makes the tableware not easy to shake left and right and has good stability.

[0039] Please refer to the appendix Figures 2-4 , in some embodiments of the present application, the support arm 231 is an angle iron structure, including a first vertical portion 233 extending outward from the mounting portion 232 and a first horizontal portion 234 bent horizontally from the top end of the first vertical portion 233, and the first horizontal portion 234 is flush with the top surface of the auxiliary support beam 210.

[0040] In this embodiment, by setting the support arm 231 as an angle iron structure, not only the processing and manufacturing of the support arm 231 are relatively simple, but also the support arm 231 has good strength. Of course, in other embodiments of the present application, the support arm 231 may also be a block structure, a tubular structure, etc.

[0041] Please refer to the appendix Figures 2-3 , in some embodiments of the present application, there are two support columns 220, front and back, at the bottom of each auxiliary support beam 210, and a wire management bin 240 is provided between the two support columns 220. The wire management bin 240 is a hollow box-shaped structure, and a wire routing opening 241 is provided in a hollowed-out manner at the top end of the wire management bin 240, and the wire routing opening 241 is configured to receive the cables at the bottom of the table into the wire management bin 240.

[0042] In this embodiment, a cable management bin 240 is provided between two pillars 220, so that the cables under the table can be organized and stored through the cable management bin 240, avoiding the disorderly accumulation of cables under the table, making the table more tidy and beautiful, and expanding the function of the table to improve practicality.

[0043] Please refer to the attached Figures 5-6 In some embodiments of the present application, the cable management bin 240 is a split structure, including a left baffle 242 and a right baffle 243 spliced ​​together on the left and right sides. The left baffle 242 and the right baffle 243 are detachably connected by a snap-on assembly. The snap-on assembly includes a clamping head 244 and a clamping slot 245. The clamping head 244 is arranged on one of the left baffle 242 and the right baffle 243, and the clamping slot 245 is arranged on the other of the left baffle 242 and the right baffle 243.

[0044] In this embodiment, the wire management bin 240 is formed by a left baffle 242 and a right baffle 243 being snap-connected and assembled, so that the installation and disassembly operations of the wire management bin 240 are relatively simple, thereby making packaging and transportation relatively convenient.

Therefore, the installation and disassembly operations of the wire management bin 240 are relatively simple.

[0047] Please refer to the attached Figures 2-3, in some embodiments of the present application, along the horizontal direction, there is a spacing between the struts 220 located on the front and rear sides and the front and rear ends of the auxiliary support beam 210.

Moreover, the auxiliary support beam 210 is connected to the transverse support beam 110 through the second strengthening parts 250, thereby enhancing the strength of the transverse support beam 110, avoiding bending of the transverse support beam 110 after being compressed, and ensuring the stability of the tableware.

[0050] Please refer to the attached Figure 7 , in some embodiments of the present application, the transverse support beam 110 is of a split structure, including a plurality of sub-rods 111 spliced end to end along the length direction. The second strengthening part 250 fits on the splicing part of two adjacent sub-rods 111, and the left and right sides of the second strengthening part 250 are detachably connected to the two sub-rods 111 respectively.

Moreover, the size of the main frame 1 can be adjusted by adding or reducing the auxiliary support beam 210 and the sub-rods 111 between the main 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 tableware are relatively convenient.

[0052] Please refer to the attached Figure 7 , in some embodiments of the present application, the second strengthening part 250 is of an angle iron structure, including a second horizontal part 251 extending along the horizontal direction at the top and a second vertical part 252 perpendicular to the second horizontal part 251. The cross-section of the transverse support beam 110 is U-shaped and the opening side of the transverse support beam 110 faces the auxiliary support beam 210. The area surrounded by the middle of the transverse support beam 110 forms a second installation groove 112. The second strengthening part 250 is snapped into the second installation groove 112, and the second horizontal part 251 and the second vertical part 252 are attached to the inner edge of the transverse support beam 110.

[0053] In this embodiment, by setting the second reinforcing member 250 as an angle iron structure, the second reinforcing member 250 can fit along the inner edge of the transverse support beam 110, further enhancing the connection strength between the second reinforcing member 250 and the transverse support beam 110. Moreover, both the horizontal portion 132 and the vertical portion 133 are connected to the auxiliary rods 111 on both sides by means of screw connections, ensuring the connection strength between the second reinforcing member 250 and the auxiliary rods 111 while making the installation and disassembly operations between the two relatively simple.

[0054] Among them, please refer to the attached Figure 8 , a third reinforcing member 131 is provided between the transverse support beam 110 and the longitudinal support beam 120. The third reinforcing member 131 is of an angle iron structure, and the left and right sides of the third reinforcing member 131 respectively fit along the inner edges of the transverse support beam 110 and the longitudinal support beam 120, enhancing the connection strength between the transverse support beam 110 and the longitudinal support beam 120, thereby further enhancing the stability of the main frame 1.

[0055] Please refer to the attached Figure 9 , the embodiment of the present application further provides a combined table, including a plurality of table boards 3 and a frame auxiliary support structure. The area enclosed between any auxiliary rods 111 that are symmetric with each other in the front-back direction and the auxiliary support beams 210 or longitudinal support beams 120 on their left and right sides forms a support area 301. Each support area 301 is connected with a table board 3, so that a plurality of table boards 3 can be spliced into a whole along the length direction of the main frame 1.

[0056] In this embodiment, by installing the table board 3 in the support area 301 divided on the main frame 1, when manufacturing the combined table, it is not necessary to separately manufacture table boards of different lengths according to the size of the main frame 1. Only the number of corresponding table boards 3 needs to be selected according to the number of support areas 301 on the main frame 1 and then lapped, thereby making the processing and manufacturing operations of the combined table relatively convenient.
