Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to a bottom plate of a mahjong machine. Background Art

[0002] The mahjong machine was born in Japan. The working principle of the mahjong machine is that the cards with the back facing up are attracted by the magnetic ring on the shuffle barrel, rotate with the magnetic ring and are sent to the conveying trough, and are pushed into piles by the stacking motor at the head of the machine and pushed away by the chain rod. The cards without magnetism on the front continue to rotate on the plate (single-port machine principle). It has been upgraded to a four-port machine. A Chinese patent discloses a mahjong machine bottom plate (authorization announcement number CN

[0003] 207734591U), the square metal plate body described in the patent technology, the center of the top surface of the metal plate body is concave downward to form a central concave portion, the four sides of the metal plate body are bent inward to have folded edges, the bottom surface of the metal plate body is provided with at least one reinforcing rib, the reinforcing rib radiates outward from the central concave portion to the four corners of the metal plate body, a wiring groove is formed between the reinforcing rib and the bottom surface of the metal plate body, the inner end of the reinforcing rib is connected to the side wall of the central concave portion, a first wiring hole connected to the wiring groove is provided at the connection between the side wall of the central concave portion and the reinforcing rib, a second wiring hole connected to the wiring groove is provided at the position of the top surface of the metal plate body corresponding to the reinforcing rib, the transmission line (including The signal and power line) pass through the first wiring hole through the wiring groove to the second wiring hole and enter the top of the bottom plate. The first wiring hole, the second wiring hole and the wiring groove are set on the bottom plate for the transmission line to be routed, which is conducive to the neatness and orderliness of the bottom plate wiring. The reinforcing rib is a sheet metal part, and the wiring groove is formed by the reinforcing rib bending downward. In order to strengthen the strength of the reinforcing rib itself and thus enhance the strength of the bottom plate, at least two reinforcing parts with different gradients are formed at the bottom of the reinforcing rib, which are divided into a first reinforcing part, a connecting part and a second reinforcing part from the outside to the inside, wherein the first reinforcing part is closer to the bottom surface of the metal plate body than the second reinforcing part, and the connecting part connects the first reinforcing part and the second reinforcing part. This arrangement is that the reinforcing rib itself has an upper and lower gradient, so that the strength of the reinforcing rib itself is better, but the design does not have a fixing device for the wiring, and when the mahjong table is working, it will vibrate, which is easy to cause entanglement and damage the operation of the mahjong machine. Therefore, those skilled in the art provide a mahjong machine bottom plate to solve the problems raised in the above background technology. Utility Model Content
