Technical Field

[0001] This utility model relates to the field of table technology, specifically to a table component with a modular tabletop. Background Technology

[0002] Tables, also known as desks, are essential household items, widely used in schools, homes, and offices. To reduce the space they take up when stored, some tables feature modular tabletops.

[0003] For example, our company previously disclosed a dual-panel multi-functional height-adjustable desk assembly in Chinese patent document CN221059899U, which includes a desktop support frame connected to a desktop motherboard. The desktop motherboard is detachably connected to a desktop expansion board. The junction of the desktop motherboard and the desktop expansion board is provided with opposing inserts and slots. The inserts can be inserted into the slots to form a limiting fit between the two. The junction of the desktop expansion board and the desktop motherboard is provided with a splicing device, which is used to lock or unlock the desktop expansion board and the desktop motherboard.

[0004] In the above technical solution, splicing between tabletops is mainly achieved through a splicing device. Since the splicing device is located on the back of the tabletop, the splicing structure can be hidden to improve the overall aesthetics of the tabletop after splicing.

[0005] However, during long-term use, it was found that after the tabletops were spliced ​​together, the load was mainly borne by the splicing device at the joints, which limited the overall load-bearing capacity and affected the overall stability of the table. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a table component with a modular tabletop that can be spliced ​​together while improving the overall load-bearing capacity.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tabletop assembly with a connectable tabletop, comprising a main tabletop and a desktop expansion board. Two mutually perpendicular support frames are located below the main tabletop and the desktop expansion board, both on the same plane. One end of each support frame extends below the main tabletop as a connecting end, and the other end extends below the desktop expansion board as an extension end. The connecting end and the extension end are respectively provided with a first column and a second column. The first column, the second column, and the support frames work together to support the main tabletop and the desktop expansion board. A movable splicing device is provided on the support frame. The splicing device is used to move to the junction of the main tabletop and the desktop expansion board to lock or unlock them.

[0008] The present invention is further configured such that: the splicing device includes two opposing connecting seats, and the connecting seats on both sides are respectively provided with a first arc-shaped guide groove and a second arc-shaped guide groove. The second arc-shaped guide groove can communicate with the first arc-shaped guide groove. The first arc-shaped guide groove is provided with a first locking block that can slide along the first arc-shaped guide groove. The second arc-shaped guide groove is provided with a second locking block that can slide along the second arc-shaped guide groove. The first locking block and the second locking block can achieve the connection or separation between the two connecting seats by sliding into or out of the second arc-shaped guide groove and the first arc-shaped guide groove, respectively.

[0009] The present invention is further configured such that: the support frame is provided with a recessed clearance space, the support frame is provided with a sliding groove at the clearance space, the bottom of the connecting seat is provided with a flange, the flange is rotatably connected to a pulley, the pulley is coupled to the sliding groove, and a sliding fit can be formed between the two.

[0010] The present invention is further configured such that: the bottom of the desktop motherboard and the desktop expansion board are provided with a first connection hole at the junction; the two sides of the connecting seat are provided with outwardly extending connecting portions; the connecting portions are provided with a second connection hole that is opposite to the first connection hole; and the first connection hole and the second connection hole are connected by a locking member.

[0011] The present invention is further configured such that: the connecting end is provided with a first connecting ear for connecting to the support frame, the extension end is provided with a second connecting ear for connecting to the support frame, the top of the first column is provided with a first connecting plate, the first connecting plate is detachably connected to the first connecting ear, the top of the second column is provided with a second connecting plate, the second connecting plate is detachably connected to the second connecting ear.

[0022] like Figures 1 to 5 As shown, this utility model discloses a table assembly with a modular tabletop, including a desktop main board 1 and a desktop extension board 2. Two support frames 3 located on the same plane and perpendicular to each other are provided below the desktop main board 1 and the desktop extension board 2. One end of the support frame 3 extends to the bottom of the desktop main board 1 as a connecting end 31, and the other end extends to the bottom of the desktop extension board 2 as an extension end 32. The connecting end 31 and the extension end 32 are respectively provided with a first column 4 and a second column 5.

[0023] Specifically, a first connecting ear 10 integrally connected to the support frame 3 is provided on the connecting end 31, and a second connecting ear 11 integrally connected to the support frame 3 is provided on the extension end 32. The top of the first column 4 is connected to the first connecting plate 41 by a thread. The first connecting plate 41 and the first connecting ear 10 are respectively provided with corresponding holes. Thus, the first connecting plate 41 and the first connecting ear 10 can be detachably connected by bolts and nuts. Similarly, the top of the second column 5 is connected to the second connecting plate 51 by a thread. The second connecting plate 51 and the second connecting ear 11 are respectively provided with corresponding holes. Thus, the second connecting plate 51 and the second connecting ear 11 can be detachably connected by bolts and nuts. Therefore, after the first column 4 and the second column 5 are respectively connected to the support frame 3, the first column 4, the second column 5 and the support frame 3 work together to support the desktop motherboard 1 and the desktop extension board 2 after they are spliced ​​together, so as to improve the overall load-bearing capacity.

[0024] In this embodiment, the splicing between the desktop motherboard 1 and the desktop expansion board 2 is mainly achieved through the splicing device 6 set on the support frame 3. After the splicing device 6 moves to the junction of the desktop motherboard 1 and the desktop expansion board 2, it locks or unlocks the desktop motherboard 1 and the desktop expansion board 2. Furthermore, the splicing device 6 can move along the extension direction of the support frame 3, thus adapting to different splicing positions between different desktop motherboards 1 and desktop expansion boards 2, thereby expanding the scope of application.

[0025] In this embodiment, the overall structure of the splicing device 6 is the same as that of the splicing device 6 disclosed in announcement number CN221059899U, that is, it mainly includes two opposing connecting seats 61. The two connecting seats 61 are respectively provided with a first arc-shaped guide groove 64 and a second arc-shaped guide groove 65. The second arc-shaped guide groove 65 can communicate with the first arc-shaped guide groove 64. The first arc-shaped guide groove 64 is provided with a first locking block 62 that can slide along the first arc-shaped guide groove 64. The second arc-shaped guide groove 65 is provided with a second locking block 63 that can slide along the second arc-shaped guide groove 65. The first locking block 62 and the second locking block 63 can achieve the connection or separation between the two connecting seats 61 by sliding into or out of the second arc-shaped guide groove 65 and the first arc-shaped guide groove 64 respectively.

[0026] In addition, the bottom of the desktop motherboard 1 and the desktop expansion board 2 are provided with a first connection hole at the junction. The two sides of the connecting seat 61 are provided with outwardly extending connecting parts 611. The connecting parts 611 are provided with a second connection hole 611a that can be opposite to the first connection hole. The first connection hole and the second connection hole 611a are connected by a locking member. It should be noted that the locking member here is a screw. The first connection hole and the second connection hole 611a are both threaded holes. Thus, after the splicing device 6 is moved to the target position, the screw is screwed into the first connection hole and the second connection hole 611a to fix the two connecting seats 61 in the splicing device 6 to the desktop motherboard 1 and the desktop expansion board 2 respectively. Then, by rotating the first locking block 62 and the second locking block 63, the second arc-shaped guide groove 65 and the first arc-shaped guide groove 64 can be slid in or out respectively, so as to realize the connection or separation between the two connecting seats 61, thereby realizing the locking or unlocking of the desktop motherboard 1 and the desktop expansion board 2.

[0027] In this embodiment, the splicing device 6 is movable along the extension direction of the support frame 3. The support frame 3 has a recessed clearance space 33, and a groove 7 is located in the clearance space 33. The bottom of the connecting seat 61 has a flange 8, which is rotatably connected to a pulley 9 via a pin. The pulley 9 is coupled to the groove 7, forming a sliding fit between them. Thus, by pushing the connecting seat 61, the pulley 9 can slide along the groove 7, thereby guiding the movement of the connecting seat 61 and ensuring its stability during movement. Furthermore, since the groove 7 is connected to the support frame 3, the support frame 3 can support the connecting seat 61, allowing the connecting seat 61 to be supported by the support frame 3 when under force.

[0028] In this embodiment, a protruding positioning protrusion 411 is provided on the first connecting plate 41, and a positioning groove opposite to the positioning protrusion 411 is provided at the bottom of the desktop motherboard 1. Positioning pins 12 and positioning holes 101 opposite to each other are provided at the junction of the desktop motherboard 1 and the desktop expansion board 2. When the desktop motherboard 1 and the desktop expansion board 2 are connected to the support frame 3 and spliced, the positioning protrusion 411 and the positioning groove enable the desktop motherboard 1 to be quickly positioned by aligning the positioning groove with the positioning protrusion 411 when installing the desktop motherboard 1. After the desktop motherboard 1 is installed, the positioning pins 12 and the positioning holes 101 enable the desktop expansion board 2 to be quickly positioned by aligning the positioning pins 12 with the positioning holes 101 when splicing the desktop expansion board 2 with the desktop motherboard 1. Then, the splicing of the desktop expansion board 2 and the desktop motherboard 1 can be completed by the splicing device 6. In this way, the splicing of the desktop motherboard 1 and the desktop expansion board 2 can be effectively improved by setting two positioning structures.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
