Description

Technical Field

[0001] The utility model generally relates to the technical field of desks, and specifically relates to a crossbeam expansion structure and a desk. Background Art

[0002] In daily life, people often need to use desks to carry objects such as computers, books, food, etc. In order to carry more objects, existing desks usually add additional expansion components such as auxiliary table boards or storage cabinets on both sides of the main table board, so as to increase the desktop space.

[0003] The bottom of the main table board of this type of desk is supported by a crossbeam extending along the length direction of the table board. Both sides of the crossbeam extend horizontally outwards to form support arms, and the support arms support the bottom of the top plate of the auxiliary table board or the storage cabinet, so that the auxiliary table board and the storage cabinet can be connected to the side of the main table board, and the top surfaces of the auxiliary table board and the storage cabinet can be flush with the top surface of the main table board; alternatively, the storage cabinet can be directly placed on both sides of the main table board by arranging multiple support legs at the bottom.

[0004] However, the above solutions have the following problems: Since the support arms are formed by extending the crossbeam, when the auxiliary table board or the storage cabinet is pressed, the support arms will conduct torque to the crossbeam; due to the large span of the crossbeam and poor anti-torque performance, when the items placed on the auxiliary table board or the storage cabinet are heavy, the crossbeam is prone to bending tendency due to excessive torque, which will in turn cause the auxiliary table board or the storage cabinet to tilt and form a gap with the main table board, affecting the stability and support of the desk. If the storage cabinet is placed on both sides of the main table board by arranging support feet at the bottom, since the height of the support feet and the storage cabinet is difficult to accurately control, it is difficult to make the top surface of the storage cabinet flush with the top surface of the main table board, affecting the aesthetics of the desk; moreover, the distance between the bottom surface of the storage cabinet and the ground is small, and blocked by the support feet, it is difficult for cleaning tools such as brooms and floor sweeping robots to reach the bottom of the storage cabinet, resulting in difficult cleaning of the bottom of the storage cabinet and easy accumulation of dust. Summary of the Invention

[0005] In view of the above defects or deficiencies in the prior art, it is desirable to provide a crossbeam expansion structure and a desk. By forming support arms on the table leg assembly, the torque applied by the support arms will be transmitted from the table leg connector and the table legs to the ground, so that the table leg assembly has better anti-torque performance, thereby making the crossbeam expansion structure have better support and stability. Moreover, only through the support arms can the external storage cabinet be stably supported, so that the external storage cabinet can be suspended on both sides of the crossbeam, which can not only ensure the flatness between the top surface of the external storage cabinet and the main table board, but also make the space at the bottom of the external storage cabinet easy to clean.

[0006] The effects of the present utility model are achieved as follows:

[0007] In a first aspect, the present application provides a crossbeam expansion structure, including two parallel crossbeams configured to support a main tabletop. Table leg assemblies are provided on both the left and right sides of the crossbeams. The table leg assembly includes a table leg connecting member vertically disposed between the two crossbeams and table legs vertically disposed at the front and rear ends of the table leg connecting member. Each side of the table leg assembly extends away from the crossbeam to form a plurality of support arms configured to support an expansion member. When the support arms are compressed, the support arms and the table leg assembly jointly bear the pressure.

[0008] Further, the support arms are provided at the positions near the table legs at the front and rear ends of the table leg connecting member. The table leg connecting member and the two table legs are integrated into one body. The support arms are close to the table legs, so that the torque applied by the support arms can be better transmitted to the table legs, thereby avoiding excessive bending of the table leg connecting member due to excessive torque. That is, the table legs bear the pressure received by the support arms. As the table legs are the core support members of the crossbeam and the tabletop, their structural stability is the strongest. Therefore, this method further improves the supportability and stability of the crossbeam expansion structure.

[0009] Further, the support arms are sheet metal parts, including a supporting portion horizontally disposed at the top end and supporting portions vertically disposed on both the front and rear sides of the supporting portion. By setting the support arms as sheet metal parts bent in a U-shape, not only can the strength of the support arms be ensured, but also the support arms are lighter in weight and apply less torque to the table leg assembly.

[0010] Further, from the side attached to the table leg assembly towards the direction away from the crossbeam, the height of the supporting portion gradually decreases. The bottom of the supporting portion is in an upwardly inclined state. When the supporting portion is compressed, the pressure received by the supporting portion will be dispersed by the inclined bottom, so that the overall strength of the support arm is better and it is not easily bent after being compressed.

[0011] In a second aspect, the present application further provides a tableware, including a main tabletop, an expansion member, and a crossbeam expansion structure. The crossbeam is supported on the bottom surface of the main tabletop. The expansion member includes a secondary tabletop, and the secondary tabletop is connected to the support arms, so that the secondary tabletop is attached to the side end of the main tabletop. By providing the secondary tabletop, the tabletop space of the tableware is expanded, and more objects can be supported; and, the secondary tabletop has better support strength and stability.

[0012] Further, the main tabletop and the secondary tabletop are also connected by a plurality of balancing members. The balancing members are plate-like structures. The left and right parts of the top surface of the balancing member are respectively connected to the bottom surface of the main tabletop and the bottom surface of the secondary tabletop. The balancing members are configured to keep the main tabletop and the secondary tabletop horizontal. By providing the balancing members to support the bottom surfaces of the main tabletop and the secondary tabletop, not only the connection strength between the main tabletop and the secondary tabletop is improved, but also the main tabletop and the secondary tabletop are connected to the horizontal top surface of the balancing member, so that the two can remain horizontal after connection, thereby ensuring the flatness of the tableware surface.

[0013] In a third aspect, the present application further provides a tableware, including a main table board, an expansion member, and a crossbeam expansion structure. The crossbeam is supported on the bottom surface of the main table board. The expansion member includes an external hanging cabinet, and the external hanging cabinet includes a top plate at the top and side plates vertically arranged on both sides of the top plate. The side plates are hollowed out with a first avoidance opening for avoiding the support arm. When the external hanging cabinet is connected to the side end of the main table board, the support arm passes through the first avoidance opening and is supported on the bottom surface of the top plate. By providing the external hanging cabinet, the top plate is connected to the main table board, so that the desktop space of the tableware is expanded, more objects can be supported, and more objects can be accommodated inside the external hanging cabinet, which has better practicability. Moreover, the external hanging cabinet has better support strength and stability.

[0014] Furthermore, the main table board and the top plate are also connected by a plurality of balancing members. The side plates are hollowed out with a plurality of second avoidance openings for avoiding the balancing members. The balancing members are plate-shaped structures. One end of the balancing member passes through the second avoidance opening and is connected to the bottom surface of the top plate, and the other end of the balancing member is connected to the bottom surface of the main table board. The balancing members are configured to keep the main table board and the top plate horizontal. By providing the balancing members to support the bottom surfaces of the main table board and the top plate, not only the connection strength between the main table board and the external hanging cabinet is improved, but also the main table board and the top plate are connected to the horizontal top surface of the balancing members, so that the two can remain horizontal after connection, thus ensuring the flatness of the surface of the tableware.

[0015] Furthermore, a plurality of angle irons are also arranged between the main table board and the side plates. The horizontal plane of the angle iron is connected to the bottom surface of the main table board, and the vertical plane of the angle iron is connected to the side surface of the side plate. By providing the angle irons to be respectively connected to the main table board and the side plates, the connection strength between the main table board and the external hanging cabinet is further improved, and the support strength and stability of the external hanging cabinet are ensured.

[0016] For the crossbeam expansion structure and the tableware provided by the present application, by extending the support arm on the table leg assembly, since the table legs are supported on the ground, the torque applied by the support arm will be transmitted from the table leg connecting piece and the table legs to the ground. The table leg assembly has good anti-torque performance. Even if the pressure received by the support arm is large, the table leg assembly is not easy to bend, so that the crossbeam expansion structure has good supportability and stability. Moreover, the external hanging cabinet can be stably supported only by the support arm, so that the external hanging cabinet does not need to be provided with support feet and can be suspended on both sides of the crossbeam. This not only ensures the flatness between the top surface of the external hanging cabinet and the main table board, but also makes the space at the bottom of the external hanging cabinet convenient for cleaning.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0026] Please refer to the attached Figure 1-6 The embodiment of the present application provides a beam extension structure, including two parallel beams 1, the beams 1 are configured to support the main table board 4, and table leg assemblies 2 are arranged on the left and right sides of the beams 1. The table leg assemblies 2 include table leg connectors 210 vertically arranged between the two beams 1 and table legs 220 vertically arranged at the front and rear ends of the table leg connectors 210. The table leg assemblies 2 on each side extend in a direction away from the beams 1 to form a plurality of support arms 3, and the support arms 3 are configured to support the extension components. When the support arms 3 are compressed, the support arms 3 apply torque to the table leg assemblies 2.

[0027] In this embodiment, the support arm 3 is formed by extending from the table leg assembly 2. Specifically, the support arm 3 can be connected to the table leg connector 210 by welding; since the table leg 220 is supported on the ground, the torque applied by the support arm 3 will be transmitted from the table leg connector 210 and the table leg 220 to the ground, so that the table leg assembly 2 has a good anti-torque performance. Even if the support arm 3 is subjected to a large pressure, the table leg assembly 2 is not easy to bend, so that the crossbeam expansion structure has good support and stability. In addition, the external cabinet 5b can be stably supported only by the support arm 3, so that the external cabinet 5b does not need to be provided with support feet, and can be suspended on both sides of the crossbeam 1, which not only ensures the flatness between the top surface of the external cabinet 5b and the main table board 4, but also makes the space at the bottom of the external cabinet 5b easy to clean.

[0028] Please refer to the attached Figure 3 In some embodiments of the present application, the support arm 3 is disposed at the front and rear ends of the table leg connector 210 near the table leg 220. The anti-torque performance of the table leg 220 is stronger than that of the horizontally disposed table leg connector 210. The support arm 3 is close to the table leg 220, so that the torque applied by the support arm 3 can be better transmitted to the table leg 220, thereby preventing the table leg connector 210 from being bent due to excessive torque, and further improving the support and stability of the crossbeam extension structure.

[0029] In other embodiments of the present application, the support arm 3 may also be directly extended from the table leg 220, so that the torque applied by the support arm 3 can directly act on the table leg 220 to ensure stability and support.

[0030] Please refer to the attached Figure 3 In some embodiments of the present application, the support arm 3 is a sheet metal part, including a support portion 310 horizontally arranged at the top and support portions 320 vertically arranged at the front and rear sides of the support portion 310. By setting the support arm 3 as a sheet metal part bent in a U shape, not only the strength of the support arm 3 can be ensured, but also the weight of the support arm 3 is light, and the torque applied to the table leg assembly 2 is smaller.

[0031] Please refer to the attached Figure 3 In some embodiments of the present application, the height of the support portion 320 gradually decreases from the side that fits the table leg assembly 2 toward the direction away from the crossbeam 1. This makes the bottom of the support portion 320 tilt upward, so that when the supporting portion 310 resists pressure, the pressure on the support portion 320 will be dispersed by the tilted bottom, thereby making the overall strength of the support arm 3 better and not prone to bending after being compressed.

[0032] Please refer to the attached Figure 1-4, embodiments of the present application further provide a tableware, including a main table board 4, an expansion member, and a crossbeam expansion structure. The crossbeam 1 is supported on the bottom surface of the main table board 4. The expansion member includes a secondary table board 5a, and the secondary table board 5a is connected to the support arm 3, so that the secondary table board 5a fits against the side end of the main table board 4.

[0033] In this embodiment, by providing the secondary table board 5a, the desktop space of the tableware is expanded, and more objects can be supported. Moreover, the pressure received by the secondary table board 5a is transmitted to the table leg assembly 2 through the support arm 3 and then transmitted to the ground by the table leg assembly 2, without exerting pressure on the crossbeam 1 at the bottom of the main table board 4, so that the secondary table board 5a has good support strength and stability.

[0034] Please refer to the appendix Figure 4 , in some embodiments of the present application, the main table board 4 and the secondary table board 5a are also connected by a plurality of balancing members 6. The balancing members 6 are plate-like structures. The left and right parts of the top surface of the balancing member 6 are respectively connected to the bottom surface of the main table board 4 and the bottom surface of the secondary table board 5a. The balancing member 6 is configured to keep the main table board 4 and the secondary table board 5a horizontal. By providing the balancing members 6 to support the bottom surfaces of the main table board 4 and the secondary table board 5a, not only the connection strength between the main table board 4 and the secondary table board 5a is improved, but also the main table board 4 and the secondary table board 5a are connected to the horizontal top surface of the balancing member 6, so that the two can remain horizontal after connection, thus ensuring the flatness of the tableware surface.

[0035] Among them, four connection holes are provided on the balancing member 6 and are distributed diagonally. The balancing member 6 is respectively threadedly connected to the main table board 4 and the secondary table board 5a through the connection holes on both sides, so that the connection strength between the three is relatively high.

[0036] Please refer to the appendix Figure 1-4 , embodiments of the present application further provide a tableware, including a main table board 4, an expansion member, and a crossbeam expansion structure. The crossbeam 1 is supported on the bottom surface of the main table board 4. The expansion member includes an external cabinet 5b. The external cabinet 5b includes a top plate 510 at the top and side plates 520 vertically arranged on both sides of the top plate 510. A first avoidance opening 521 for avoiding the support arm 3 is hollowed out on the side plate 520; when the external cabinet 5b is connected to the side end of the main table board 4, the support arm 3 passes through the first avoidance opening 521 and supports on the bottom surface of the top plate 510.

[0037] In this embodiment, by providing an external cabinet 5b, the top plate 510 is connected to the main table board 4, so that the desktop space of the tableware is expanded, more objects can be supported, and more objects can be accommodated inside the external cabinet 5b, which has better practicability. Moreover, the pressure received by the top plate 510 is transmitted to the table leg assembly 2 through the support arm 3 and then transmitted to the ground by the table leg assembly 2, without exerting pressure on the cross beam 1 at the bottom of the main table board 4, so that the external cabinet 5b has better support strength and stability. Not only that, the external cabinet 5b does not need to be provided with support feet and can be suspended on both sides of the cross beam 1, which not only ensures the flatness between the top surface of the external cabinet 5b and the main table board 4, but also makes the space at the bottom of the external cabinet 5b easy to clean.

[0038] Please refer to the attached Figure 5-6 , in some embodiments of the present application, the main table board 4 and the top plate 510 are further connected by a plurality of balancing members 6. A plurality of second avoidance openings 522 for avoiding the balancing members 6 are provided in the side plate 520 in a hollowed-out manner. The balancing member 6 is in a plate-like structure.
