Description

Technical Field

[0001] The utility model relates to the technical field of a mahjong machine lifting mechanism, in particular to a lifting device for an operating panel of a mahjong machine. Background Art

[0002] The lifting function of the mahjong machine's operating panel is an indispensable and convenient design in modern mahjong entertainment equipment. Through the precise mechanical structure and intelligent control system, the user only needs to lightly press the lifting button on the operating panel, and the operating panel will automatically rise or fall smoothly and quickly. This design not only greatly improves the fluency and fun of the game, but also makes the preparation work such as changing cards and tidying up the table simple and quick, saving a lot of time for players.

[0003] like Figure 3 As shown, the existing lifting rods connected to the operating panel of the mahjong machine are directly slidably connected to the base. In order to ensure the free fall of the lifting rod, the connection between the components is relatively loose, and there is a gap between the lifting rod and the base. The lifting trajectory of the lifting rod is only constrained by the concave plate frame and the sliding joint below. Therefore, the existing mahjong machine operating panel has the following technical problems during use:

[0004] Since there is a gap between the lifting rod and the base, and only the trajectory is restricted by using components in the lower half of the lifting rod, the upper end of the lifting rod is still easy to shake, which makes the mahjong machine operating panel easy to shake, causing the mahjong machine operating panel to always collide or scratch the table top, easily damaging the table top. Summary of the invention

[0005] The main purpose of the utility model is to overcome the deficiencies in the prior art and provide a lifting device for an operating plate of a mahjong machine.

[0006] The technical solution adopted by the utility model to achieve its technical purpose is: a lifting device for a mahjong machine operating plate, including a lifting rod and a base, a linear bearing is arranged between the lifting rod and the base, and the lifting rod is slidably connected to the inside of the base through the linear bearing; through the arrangement of the linear bearing, the gap between the lifting rod and the base can be filled, so that the lifting rod will not shake when driving the mahjong machine operating plate to move up and down.

[0007] A concave plate frame is fixedly connected to one side of the base, and an annular hoop is fixedly sleeved on the bottom end of the lifting rod. A sliding joint corresponding to the position of the vertical plate of the concave plate frame is fixedly provided on the annular hoop, and the sliding joint is slidably connected in a sliding groove opened inside the concave plate frame.

[0008] Preferably, a top plate is fixedly mounted on one side of the annular clamp, and a cam and a motor are arranged below the top plate. The cam is driven to rotate by the motor, so that the cam drives the top plate to move up and down.

[0009] Preferably, the sliding joint is configured as a bolt head, one end of which is threadedly connected to the inside of the annular clamp, and the other end of which is slidably connected to the sliding groove.

[0010] Preferably, the concave plate frame transverse plate position is also threadedly connected with an adjusting rod, and one end of the adjusting rod is against the bottom of the lifting rod; through the setting of the adjusting rod, the lifting rod can be lowered to different heights, that is, the lifting height of the lifting rod can be adjusted, so as to make the mahjong machine operating panel and the mahjong machine table top remain flush.

[0011] Preferably, a connecting buckle is fixedly connected to the other side of the annular clamp, a guide rod is connected through the connecting buckle, one end of the guide rod is fixed to the bottom of the base, and the other end is fixed to the horizontal plate position of the concave plate frame; through the connecting buckle and the guide rod, the lifting trajectory of the lifting rod is further restricted to increase its lifting stability.

[0012] Preferably, a fixed joint is fixedly installed on the outer wall of the lifting rod, and a spring is fixedly arranged between the fixed joint and the position of the concave plate frame cross plate; through the arrangement of the fixed joint and the spring, one end of the spring is hooked on the fixed joint, and the other end is hooked on the concave plate frame cross plate, so that after the lifting rod rises, the lifting rod can be pulled down under the action of the spring, avoiding the problem that the lifting rod is not easy to fall freely due to the large friction force on the lifting rod.

[0013] Preferably, the fixing joint is configured as a screw head, one end of which is threadedly connected to the inside of the annular clamp, and the other end is used to connect to the spring.

[0014] Preferably, the linear bearing may not be arranged between the lifting rod and the base, and the linear bearing may be arranged between the guide rod and the connecting buckle.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The lifting device for the operating plate of the mahjong machine can fill the gap between the lifting rod and the base by setting a linear bearing, so that the lifting rod will not shake when driving the operating plate of the mahjong machine to move up and down; and the lifting trajectory of the lifting rod is further restricted by the connecting buckle and the guide rod, thereby increasing the lifting stability; and under the action of the spring, the lifting rod is pulled down after it rises, which can avoid the problem that the lifting rod is not easy to fall freely due to the large friction force on the lifting rod.
