Detailed implementation manner

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0027] This embodiment discloses a table. Compared with a conventional table, it also has a table board 25 for working. The table board 25 is supported by four table legs 19. The differences between the table disclosed in the present utility model and the conventional table will be introduced in detail in the following several embodiments.

[0028] Embodiment 1:

[0029] Refer to Figures 1-9, specifically an assembled table. The bottom surface of the tabletop 25 is the connecting surface, and threaded holes 26 are opened on it. The table legs 19 are installed on the bottom surface of the tabletop 25 through connecting pieces. Specifically, the connecting piece includes a hollow mounting block 1. On the mounting block 1, two first connection holes 5 and two second connection holes 6 are respectively opened along two parallel straight lines. The mounting block 1 is threadedly connected to the threaded hole 26 through the first screw 17 passing through the first connection hole 5, which not only realizes fixation but also prevents the mounting block 1 from being misaligned relative to the tabletop 25, ensuring the stability of the mounting block 1 fixed on the tabletop 25. The mounting block 1 is connected to the table leg 19 through the second screw 18 passing through the second connection hole 6. With the same fixing method, it also ensures that the mounting block 1 and the table leg 19 will not be misaligned, ensuring the stability of the connection between the mounting block 1 and the table leg 19. And the second screw 18 has a nut, and the upper part of the second connection hole 6 is a hexagon that fits the peripheral surface of the nut, and the lower part is a cylindrical hole structure. During the connection of the second screw 18, the nut will not rotate, and at the same time, it has a locking effect. This method can quickly realize the installation and disassembly between the table leg 19 and the tabletop 25, and at the same time ensure the stability of the connection.

[0030] To further improve the connection stability, the connecting piece further includes a support block 2 fixedly connected to the mounting block 1, and the support block 2 and the mounting block 1 form a "T" shape. Four third connection holes 9 are opened along a straight line on the support block 2. The support block 2 is also connected to the tabletop 25 through the first screw 17 passing through the third connection hole 9. The straight line where the third connection hole 9 is located is also parallel to the straight lines where the first connection hole 5 and the second connection hole 6 are located, and the second connection hole 6 is located between the first connection hole 5 and the third connection hole 9, ensuring the uniform force of the connecting pieces on both sides of the table leg 19.

[0031] And reinforcing ribs 10 are provided on both the mounting block 1 and the support block 2. The plane where the reinforcing ribs 10 are located is perpendicular to the bottom surface of the mounting block 1, thereby forming a hollow structure of the mounting block 1 and the support block 2, reducing the weight of the connecting piece while ensuring the support strength of the connecting piece.

[0032] Regarding the convenience of use and manufacturing, the two support structures of the table leg 19 are connected to form a "U" - shaped structure, and the cross - section of the table leg 19 is circular. That is to say, the table leg 19 can be formed by directly bending a bent pipe, eliminating the need for welding steps of traditional square legs, and greatly reducing the manufacturing cost.

[0033] For the cylindrical table leg 19, a card slot 7 with an arc-shaped structure that fits the table leg 19 is provided at a position near one end of the mounting block 1. A positioning post 11 coaxial with the second connection hole 6 is arranged in the card slot 7. A positioning hole 20 that engages with the positioning post 11 is provided on the table leg 19. The second screw 18 sequentially penetrates the table leg 19 and the mounting block 1 from bottom to top and is connected to the bottom surface of the tabletop 25. By the engagement of the positioning post 11 and the positioning hole 20, the stability of the mounting block 1 when connected to the cylindrical table leg 19 can be ensured.

[0034] Moreover, a positioning block 12 is sleeved on the second screw 18. An arc-shaped surface 13 that fits the table leg 19 is provided on one end surface of the positioning block 12. The arc-shaped surface 13 cooperates with the card slot 7 with an arc-shaped structure to form a covering of the cylindrical table leg 19, which not only ensures the aesthetics of the connection but also improves the stability of the connection.

[0035] Embodiment 2:

[0036] Referring to Figures 1-3 、 Figure 5 and Figures 7-9 , on the basis of Embodiment 1, a more user-friendly design is made for the assembled table, and a table expansion structure is disclosed. By providing a mounting groove 8 on the mounting block 1, a movable hanging member 14 is detachably arranged in the mounting groove 8. The movable hanging member 14 penetrates the mounting groove 8 and extends to the lower part of the mounting block 1, which can facilitate hanging items during use. Moreover, the mounting groove 8 formed by the reinforcing rib 10 will neither increase the overall weight of the mounting block 1 nor reduce the support strength of the movable hanging member 14 when hanging heavy objects.

[0037] Specifically, the movable hanging member 14 includes a mounting plate. The mounting plate penetrates the mounting groove 8 and extends to the inside. The part extending to the inside is detachably connected to the mounting block 1 through a fastener. The mounting plate extends downward to form a detour part, which is specifically hook-shaped and can be used to directly hang items such as schoolbags, plastic bags, and so on.

[0038] In terms of details, the thickness of the mounting plate is the same as the width of the mounting groove 8, which can ensure that there is no shaking when the mounting plate is inserted into the mounting groove 8, thus ensuring the stability of the movable hanging member 14 after connection.

[0039] Specifically, the fastener includes a locking bolt 16, which has a bolt and a nut. A through hole 15 for the bolt to penetrate is provided on the mounting plate, and a groove 27 for the bolt to penetrate is provided in the mounting block 1. After the mounting plate is inserted into the mounting groove 8, the bolt and the nut are respectively attached to both sides forming the mounting groove 8, thereby realizing the fixation of the movable hanging member 14.

[0040] Another part of the expansion structure is that adjusting seats and moving seats are respectively arranged on the two support structures of the table leg 19.

[0041] Specifically, the adjusting base includes a first connecting base 21 detachably connected to one end of the support structure. A support foot 22 is threadedly connected to the bottom of the first connecting base 21. By rotating the threadedly connected support foot 22, the height of the tabletop 25 can be adjusted. The moving base includes a second connecting base 23 detachably connected to the other end of the support structure. A moving wheel 24 is inserted into the second connecting base 23. And ribs are formed on both the first connecting base 21 and the second connecting base 23, which can prevent the connecting bases from rotating after the two connecting bases are installed at the ends of the support structure.

[0042] Embodiment 3:

[0043] Referring to Figures 1-3 、 Figure 5 and Figures 7-9 , on the basis of Embodiment 1, a table splicing structure is proposed. One end of the mounting block 1 is flush with one end of the tabletop 25, and an adsorbing member is provided on the mounting block 1. When two tabletops 25 approach each other, the adsorbing member can adsorb the two mounting blocks 1, so as to achieve accurate and rapid splicing and alignment of the two tables, greatly improving the placement efficiency of the tables.

[0044] According to the two "U"-shaped table legs 19, two mounting blocks 1 are synchronously provided and fixed, and are respectively arranged at the ends in the length direction of the tabletop 25. Two adjacent tabletops 25 can be adsorbed and connected through two opposite adsorbing members.

[0045] Specifically, the adsorbing member includes a magnetic attraction block 4 made of cobalt or nickel material, that is, a magnet. A magnetic attraction groove 3 is formed in the mounting block 1, and the magnetic attraction block 4 is installed in the magnetic attraction groove 3, and the volume of the magnetic attraction groove 3 is equal to that of the magnetic attraction block 4, so as to ensure the stability after the magnetic attraction block 4 is embedded.

[0046] The opposite surfaces of the magnetic attraction blocks 4 on the two mounting blocks 1 on one table have opposite magnetic poles, so as to ensure the docking of the two tables in the same operation direction and prevent the tables from being docked in the reverse direction.

[0047] The magnetic attraction blocks 4 are provided in two groups, and the two groups of magnetic attraction blocks 4 are symmetrically arranged on the mounting block 1 to ensure that the suction force is large enough when the two tables are spliced, so as to complete rapid splicing.

[0048] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
