Specific implementation mode

The preferred embodiment of this patent is described in further detail below in conjunction with the accompanying drawings.

Mahjong machine rising mechanism as shown in Figure 1, including card bearing board 1, motor of registering the license, gear drive 3 and lifting are led Column assembly 5.

Card bearing board 1 has the supporting rack 2 with bottom cam curve below, and motor of registering the license connects with the transmission of gear drive 3 It connects, the lifting crank 4 with support frame bottom cam curve successively engaged transmission is installed, to drive on gear drive 2 Card bearing board 1 moves up and down.

Guide post lifting assembly 5 is located at the both sides of supporting rack 2, and guide post lifting assembly 5 includes guide rod 51, spring 52, upper guide post 53, lower guide post 54 and guide holder 55, the upper guide post 52 and lower guide post 53 are set as the form of hollow sleeve, are set in guide holder 55 There are the channel for Gong sliding up and down, guide rod 51 to be fixed on 1 bottom of card bearing board, guide rod 51 is set in upper guide post 52, and upper guide post 52 is set Set on lower guide post 53, the outer diameter of upper guide post 52 is less than the outer diameter of lower guide post 53, the junction of upper guide post 52 and lower guide post 53 it Between form step, lower guide post 54 is set in guide holder 55, and lower guide post 54 is fixed on mah-jong machine baseboard, spring 52 setting is leading Bar 51 and 52 periphery of upper guide post, the upper and lower ends of spring 52 are respectively by between card bearing board 1 and upper guide post 53 and lower guide post 54 Step limits, and the outer diameter of spring 52 is less than the internal diameter of guide holder 55.Wherein, the outer diameter of guide rod 51 is less than the outer of upper guide post 52 Diameter, guide rod 51 are slided up and down along 52 medial surface of upper guide post；The outer diameter of lower guide post 54 is less than the internal diameter of guide holder 55, lower 54 edge of guide post The medial surface of guide holder 55 slides up and down.In order to reduce the host thickness of mahjong machine to greatest extent, the height of upper guide post 52 with Length after spring 52 is shunk completely is suitable, and upper guide post 52 and lower guide post 53 are casing, upper guide post 52 and lower guide post 53 it is interior Portion is connected to, and the length of guide rod 51 is suitable with the total height of upper guide post 53 and lower guide post 54, the height of the inner passage of guide holder 55 Total height suitable with the total height of upper guide post 53 and lower guide post 54 or more than upper guide post 53 and lower guide post 54, makes guide post lifting group The upper end that part 5 may contract to the upper end of guide rod 51, the upper end of upper guide post 53 and guide holder 55 is concordant.

The action process of elevating mechanism is illustrated so that card bearing board 1 is from the highest point place of minimizing as an example.Such as Fig. 2 institutes Show, card bearing board 1 rises to highest point when playing a card, and is fully deployed between guide rod 51 and upper guide post 53, lower guide post 54 and guide holder 55 it Between be fully deployed.As shown in figure 3, card bearing board 1 is begun to decline, and under the action of spring 52, the lower guide post with the cooperation of guide holder 55 54 decline certain altitude first, as shown in figure 4, then card bearing board 1 continues to drop in guide holder 55, upper guide post 53 and lower guide post 54 decline together, and then guide rod 51 descends guide post 55 to decline relatively, and last card bearing board 1 drops to lowest order, guide rod 51, spring 52, Upper guide post 53 and lower guide post 54 are entirely located in guide holder 55.The uphill process of card bearing board 1 is on the contrary, in uphill process, bullet first The reaction force of spring 52 drives guide rod 51 with respect to 53 upward sliding of upper guide post, and then upper guide post 53, lower guide post 54 rise successively.
