Abstract
Description
Technical Field
[0001] This utility model relates to mahjong machines for entertainment, and in particular to a foldable bracket for a folding mahjong table. Background Technology
[0002] Current folding mahjong tables mainly consist of a table body and a folding support frame. The folding support frame includes a fixed base, uprights, and a table body fixing component. The table body fixing component is fixedly connected to the bottom of the table body. Corresponding fixing screw holes and rotating screw holes are provided on both sides of the top of the uprights and on both sides of the table body fixing component. The fixing screw holes are used to secure the table body during use, preventing rotation, while the rotating screw holes are used for the axis connection between the table body fixing component and the uprights. When folding the mahjong table, the table body fixing component rotates along the screw in the rotating screw hole, achieving the folding function. The fixed base is a rectangular or circular integral component that prevents the mahjong table from tipping over. The larger the base, the better the anti-tipping effect. However, with this type of fixed base, the area occupied by the fixed base after folding is the same as the area before folding, thus reducing the usable space, especially in smaller rooms. Therefore, inventing a foldable support frame that can achieve the folding function of a mahjong table while reducing the floor space would better meet people's needs. Summary of the Invention
[0003] To address the problems existing in folding brackets for mahjong tables, this utility model provides a foldable bracket for folding mahjong tables. This mahjong machine not only enables the folding function of the mahjong table, but also reduces the floor space occupied after folding, making it convenient to use.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: it is composed of a fixed base, a column, and a table body fixing component. The fixed base is fixedly connected to the column, and the upper side of the column is axially connected to one side of the table body fixing component. The fixed base is fixedly connected to the column, wherein a foldable base is connected to one side of the fixed base, and a crossbar is provided in the middle of the table body fixing component. One end of the crossbar is movably connected to a connecting rod, and the other end of the connecting rod is movably connected to an anchor rod on the foldable base.
[0005] Furthermore, the column is hollow, with a groove in the middle of the top of the column;
[0006] Furthermore, a groove is provided on the bottom side of the column for the connecting rod to pass through and slide up and down;
[0007] Furthermore, the connecting rod is L-shaped, passing through the column and exiting through a groove on the bottom side of the column before being movably connected to the anchor rod inside the rotatable base.
[0008] When the mahjong table is folded, the crossbar on the table body fixing component pulls the connecting rod upward, causing the connecting rod to slide upward along the sliding groove on the side of the column, which drives the foldable base to rotate upward. When the mahjong table body rotates to the vertical position, the foldable base rotates to the vertical position simultaneously.
[0009] The beneficial effects of this invention are: not only can the mahjong table body be folded, but the base can also be folded simultaneously when the table body is folded, reducing the footprint of the base and thus facilitating the use of available space. The product has a simple structure and is easy to promote. Attached Figure Description

Detailed Implementation
[0016] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "above," "top," "bottom," and "middle," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances, and therefore should not be construed as limiting this utility model. Furthermore, to clearly illustrate the motion path of the L-shaped connecting rod in this utility model, Figure 3 , Figure 4The L-shaped connecting rods hidden in the table body fixing parts, columns, fixed bases, and foldable bases are represented by dashed lines to facilitate understanding.
[0017] like Figure 1 , Figure 3 , Figure 4 As shown, the fixed base 1 is fixedly connected to the column 3. The column 3 is hollow and has a groove 6 on the top. Shaft holes 4 and 5 are provided on both sides of the groove 6. A foldable base 2 is connected to the other side of the fixed base 1. The upper side of the column 3 is movably connected to one side of the table body fixing part 8. The specific connection method is to pass the screw 13 through the shaft hole 10 on the table body fixing part 8 and the shaft hole 4 on the upper side of the column 3 in sequence and then fix it with a nut. The table body fixing part 8 can then rotate along the screw 13 to realize the folding function of the mahjong table body. At the bottom of the column 3, a groove 19 is provided for the L-shaped connecting rod 16 to pass through and slide up and down. The middle of the table body fixing component 8 has a shaft hole 11 for the crossbar 14 to pass through. The crossbar 14 passes through the shaft hole 11 and the screw hole 17 on the connecting rod 16 in sequence, fixing the connecting rod to the table body fixing component 8. The connecting rod 16 passes through the column 3 and exits through the groove 19 on the bottom side of the column. The other end of the connecting rod 16 is movably connected to the anchor rod 23 on the foldable base 2 and is limited by a screw 24 to prevent the connecting rod 16 from sliding off the anchor rod 23. The screw 22 passes through the screw hole 21 on the foldable base 2 and the screw hole 20 on the fixed base 1 in sequence, movably connecting the fixed base 1 and the foldable base 2. In this embodiment, the groove 6 adopts an inverted triangular design. In actual use, a U-shaped or other similar design can also be used, as long as the crossbar 14 does not obstruct the table body fixing component when it is in a horizontal state. Therefore, the groove 6 is not limited to this embodiment. The width of the slide groove 19 is slightly larger than the thickness of the connecting rod 16. The height of the slide groove 19 is such that the lowest point is when the foldable base 2 is in a horizontal position and the highest point is when the foldable base 2 is in a vertical position, so as to ensure that the connecting rod 16 can slide freely in the slide groove 19.
[0018] Reference Figure 3 As shown, when the mahjong table is in a horizontal position, the table fixing part 8 is also in a horizontal position. The screw 15, after passing through the screw holes 12 on the table fixing part 8 and 5 on the upright, can lock the table and prevent it from rotating. When it is necessary to fold the mahjong table, removing the screw 15 will release the lock, and lifting one side of the mahjong table will allow it to rotate along the screw 13. When the mahjong table is in a horizontal position, the connecting rod 16 provides some support to the table through the foldable base. Therefore, in practice, it is advisable to use a steel plate with a thickness of 2 mm to 4 mm for the connecting rod 16 to prevent deformation under stress and improve product stability.
[0019] Reference Figure 4As shown, when the mahjong table is folded, the table body 25 drives the table body fixing part 8 to rotate along the screw 13, and the crossbar 14 pulls the connecting rod 16 upward. The anchor rod 23 on the foldable base 2 is pulled by the connecting rod 16 and rotates upward along the screw 22. When the mahjong table body 25 is rotated to a vertical position, the foldable base 2 is simultaneously in a vertical position. The base is folded at the same time as the mahjong table body is folded. Compared with traditional bases, this utility model product reduces the footprint of the base because one side of the base can be folded.
[0020] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments. For example, in the embodiments of this utility model, the column can be set on the outside of the fixed base, then the anchor rod of the foldable base is also moved to the outside accordingly. All these modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
