Description

TECHNICAL FIELD

[0001] The utility model belongs to furniture manufacturing technical field, concretely relates to a mahjong table leg connecting mechanism. BACKGROUND

[0002] Traditional mahjong tables usually use bolts and nuts to fix the table legs to the table body. However, the existing connection methods often have some problems, such as difficult installation, unstable connection, and possible loosening or deformation during long-term use. These problems not only affect the stability of the table, but also may affect the user's experience and the service life of the furniture.

[0003] In the existing connecting mechanism, a single threaded connection is usually relied on to fix the table body to the table legs. Although the bolt connection method can provide a certain stability, the installation process is cumbersome, and once the connection is improper, it is easy to cause the table legs to loosen. In addition, the traditional connecting structure often lacks effective positioning and locking mechanisms, which may cause displacement or deformation of the connection point during use due to vibration or external force, thereby reducing the stability of the connection.

[0004] To solve these problems, existing technologies have tried to enhance the stability of the connection by adding components such as clamping blocks and positioning columns. However, these existing technical solutions still have some deficiencies, such as inaccurate positioning, difficult installation, and possible loosening during long-term use. Therefore, how to provide a simple and stable connection method to ensure the firm and reliable connection between the table body and the table legs, and to avoid deformation or loosening during long-term use, has become a technical problem to be solved in the current technology. SUMMARY

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a mahjong table leg connecting mechanism, which can realize the connection of the table body and the table legs while ensuring the stability of the connecting parts, simplifying the installation process and improving the connection stability.
