Abstract
Description
Technical Field
[0001] This utility model relates to a tube-shrinking structure for a mahjong machine table. Background Technology
[0002] Mahjong machines originated in Japan. Traditional manual mahjong requires players to shuffle and arrange the tiles themselves, a tedious and time-consuming process. Mahjong machines, however, can automate these processes, saving players significant time and effort. Mahjong machines typically resemble a table, consisting of an electric tabletop and legs for support. Traditionally, the legs are either inserted directly into pre-drilled holes or welded together. When inserted, the holes are spaced some distance from the tabletop to ensure stability; when welded, the joints have noticeable protrusions. Both methods result in an inconsistent and less aesthetically pleasing appearance, and the welded method is also more expensive. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a tube-shrinking structure for a mahjong machine table.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] A tube-shaped structure for a mahjong table includes a table body with connecting structures at its four corners. The connecting structures are characterized by having cavities within them, with a connector at the top of each cavity connected to one end of the connecting structure. The table also includes tubular legs corresponding to the connecting structures, each with an integrally formed tube end at its upper end. The tube end is inserted into the cavity of the corresponding connecting structure, and its front end engages with the bottom end of the connector. The outer diameter of the tubular legs is the same as the outer diameter of the connecting structures.
[0006] Furthermore, a frustum structure is formed between the tubular table leg and the constricted tube end; when the constricted tube end is inserted into the cavity and its front end is engaged with the bottom end of the connector, the upper part of the frustum structure abuts against the lower part of the connector structure.
[0007] Furthermore, the frustum structure has two layers; when the tube end is inserted into the cavity and the front end is engaged with the bottom end of the connector, the upper part of the frustum structure in the upper layer abuts against the lower part of the connector structure.
[0008] Compared with the prior art, this utility model has the following advantages and effects: it is easy to install and has a relatively lower production cost; it is more coherent and smooth in appearance and is relatively more beautiful. Attached Figure Description

[0012] The accompanying drawings, which are provided to further illustrate this application and form part of this application, illustrate exemplary embodiments of this application and are used to explain this application, but do not constitute an undue limitation of this application. Detailed Implementation
[0013] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0014] Example
[0015] like Figures 1-3 As shown, this embodiment includes a table body 1 and four tubular table legs 2 connected below the table body 1 to provide support for the table body 1. Connecting structures 3 are respectively provided at the four corners of the table body 1, with each connecting structure 3 corresponding to a tubular table leg 2. A cavity is opened within the connecting structure 3 for the upper end of the tubular table leg 2 to be inserted, and a connector 4 is provided at the top of the cavity, with one end fixedly connected to the connecting structure 3.
[0016] The upper end of the tubular table leg 2 is provided with an integrally formed constricted tube end 5, the outer diameter of which is the same as the outer diameter of the connecting structure 3. Specifically, the constricted tube end 5 is inserted into the cavity of the corresponding connecting structure 3 and its front end is engaged with the bottom end of the connector 4, while the tail end of the constricted tube end 5 abuts against the outer end of the cavity.
[0017] like Figures 1-3 As shown, a frustum structure 6 is formed between the tubular table leg 2 and the constricted tube end 5. The frustum structure 6 has two layers. Specifically, when the constricted tube end 5 is inserted into the cavity and its front end is engaged with the bottom end of the connector 4, the upper part of the frustum structure 6 in the upper layer abuts against the lower part of the connecting structure 3.
[0018] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
