Description

Technical Field

[0001] The utility model relates to the technical field of mahjong machines, in particular to a table leg inserted type mahjong machine frame. Background Art

[0002] like Figure 1 As shown, the bottom corners of the existing mahjong machine frame mostly use four Y-shaped pins through four square tubes and 12 screws to lock them. This method is cumbersome to install and is easy to shake after installation, forming an eight-shaped foot. Summary of the invention

[0003] In order to overcome the above problems, the utility model provides a table leg insertion type mahjong machine frame.

[0004] The technical solution adopted by the utility model is: a table leg insertion type mahjong machine frame, comprising four table legs (5) and four fences (2), two adjacent fences (2) are connected by a pipe sleeve assembly (1), and the four fences (2) are connected in sequence to form a square frame; the pipe sleeve assembly (1) comprises an outer sleeve (1-1) and an inner sleeve (1-2), the outer sleeve (1-1) comprises a first semicircular arc tube, and side wing plates are arranged on both sides of the first semicircular arc tube, and the outer sleeve (1-1) comprises a first semicircular arc tube, and side wing plates are arranged on both sides of the first semicircular arc tube. -1) are connected to two adjacent fences (2) respectively; the inner sleeve (1-2) comprises a second semi-circular arc tube, the lower end of the second semi-circular arc tube is provided with a taper, and the upper end of the second semi-circular arc tube is flattened inward along its radial direction; the second semi-circular arc tube is installed on the inner side of the first semi-circular arc tube, and the second semi-circular arc tube and the first plate semi-circular arc tube form a tube cavity; the tube cavity is in the shape of a tapered cylinder with a small upper end and a large lower end, and the upper end of the table leg (5) is inserted into the tube cavity and matched with the taper of the tube cavity.

[0005] Furthermore, reinforcing ribs are provided on the side wing plates.

[0006] Furthermore, the square frame is connected to the bottom plate (3) via a cross frame (4).

[0007] Furthermore, the diameter of the first semi-circular arc tube remains unchanged, and the flattened portion at the upper end of the second semi-circular arc tube is in an M shape.

[0008] The beneficial effects of the utility model are:

[0009] (1) The utility model adopts the table leg plug-in fixing method. The pipe sleeve is formed into a half-moon shape by two pieces of steel plates, and then welded into a pipe sleeve, which is fixed on the four corners of the mahjong machine with a mold. The welding is firm, the position is accurate, and the verticality is good. After installation, the four corners are parallel and stable and practical.

[0010] (2) The inner sleeve is concave at the top and tapered at the bottom. It can perfectly avoid the mahjong tiles and the push plate on the left side of the push-up assembly. The taper at the bottom makes the sleeve and the table leg fit seamlessly, making the mahjong table more stable and the four legs more parallel.

[0011] (3) The outer sleeve is a straight tube at the upper end, tapered at the lower end, and has trapezoidal reinforcing ribs on both sides. The presence of the trapezoidal reinforcing ribs makes the angle between the four tube sleeves of the mahjong machine frame and the fence stable and the verticality better.
