A kind of mah-jong pushing device
Technical field
The present invention relates to mahjong machine, is especially a kind of mah-jong pushing device of mah-jong pieces being delivered to card bearing board central authorities from a side of card bearing board.
Background technology
The mah-jong pieces that existing mahjong machine is shuffled in cylinder connect board seat through absorption and being sent to of transport tape of Xi Pai mechanism, stack and form after a trick connecing on board seat two boards, be pushed into and connect board plate through showdown head, the board connecing on board plate is constantly moved forward by the promotion of a rear trick, until to the pier number of setting.In such cases, connect mah-jong pieces on board plate and relatively connect one end of board seat, connect the board of this kind of situation on board plate by the parallel card bearing board that is pushed into of Mah-jongg push plate, cause also one end of card bearing board relatively of board on card bearing board, and can not arrange between two parties.More disadvantageous situation is that the mah-jong pieces that mahjong machine is used are all with magnetisable material, generally heavier.So the long-term unbalance stress of card bearing board, usually produces distortion.
Summary of the invention
The object of the invention is to provide a kind of mah-jong pushing device that mah-jong pieces can be delivered to card bearing board central authorities from a side of card bearing board, is specifically realized by following technical scheme:
Described mah-jong pushing device, be arranged at mahjong machine and connect board seat one side, comprise support, partial gear, tooth bar, wind spring and send board plate, described partial gear is upwards provided with part tooth in week, all the other arc length are smooth circular arc, described partial gear is arranged on described support bottom, support top is provided with a chute, described chute arranges along stent length direction from starting end, chute is starting end near the one end that connects board seat, this starting end is provided with smooth fillet, described tooth bar is arranged in described chute, and engage with described partial gear, described wind spring connects starting end and the tooth bar of described chute, the described board plate that send is placed in chute starting end, send bottom and the tooth bar corresponding end of board plate to be rotationally connected, tooth bar or wind spring drive under, along Slideslip on chute, in the time sending board plate bottom to touch chute starting end, rotate along described smooth fillet.
Described mah-jong pushing device, it further designs and is that the coiling center of described wind spring is arranged on described tooth bar, and its end is fixedly connected with the starting end of described chute.
Described mah-jong pushing device, it further designs and is that described partial gear engages with described tooth bar by one group of travelling gear.
Described mah-jong pushing device, it further designs and is that described tooth bar comprises tooth bar head and tooth bar body, and described tooth bar head is connected by corresponding hole and screw with described tooth bar body.
Described mah-jong pushing device, it further designs and is that described partial gear has tooth in 1/3rd arc length of root circle, and remainder is smooth circular arc.
Mah-jong pushing device provided by the invention, is sent to card bearing board central authorities by mah-jong pieces from card bearing board one side, makes card bearing board stressed more even, extends the service life of corresponding component; Tooth bar of the present invention comprises tooth bar head and tooth bar body, can change by the cooperation of adjusting both stroke that send board plate, and what adapt to different mah-jong pieces quantity send board needs.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further described:
Contrast Fig. 1 and Fig. 2, mah-jong pushing device, be arranged in automatic mahjong-playing machine, mah-jong pieces are delivered to card bearing board middle part from a side of card bearing board makes card bearing board stressed well-balanced, comprise support 1, partial gear 2, tooth bar 4, wind spring 5 and send board plate 3, partial gear 2 has tooth in 1/3rd arc length of its root circle, all the other arc length are smooth circular arc, partial gear 2 is arranged on support 1 bottom, support 1 top left end offers a chute 1a, tooth bar 4 is arranged in chute 1a, tooth bar 4 comprises tooth bar head 4a and tooth bar body 4b, on tooth bar head 4a and tooth bar body 4b, be respectively arranged with corresponding hole 4c, both connect with screw-nut having selected after the hole 4c working in coordination.Known in conjunction with Fig. 6, the left end of chute 1a is the starting end that tooth bar slides, support 1 is fillet in the upper left corner at chute 1a place, tooth bar 4 one side is down provided with tooth and engages with partial gear 2, partial gear 2 also can engage with tooth bar 4 by travelling gear 6, contrast Fig. 3, Fig. 4, Fig. 5 and Figure 11, the coiling center of wind spring 5 is arranged on tooth bar 4 and the other end of wind spring 5 is fixedly connected with the starting end of chute 1a, as shown in figure 10, send the corresponding end of board plate 3 bottoms and tooth bar 4 to be rotationally connected and to send the upside of board plate 3 two bottom sides and chute 1a to be slidably connected.
Operation is initial, send board plate 3 to be positioned at initial level state, be arranged at send board plate 3 other connect board seat 9 after receiving the mah-jong pieces 8 that mahjong machine miscellaneous part sends here, by showdown head on one side, mah-jong pieces 8 are pushed into chute 1a, on chute, accumulate after the mah-jong pieces 8 of some, in conjunction with Fig. 7 and Fig. 8, motor (not shown in FIG.) drives partial gear 2 to be with carry-over bar 4 to slide, tooth bar 4 pulls and send board plate 3 to make to send board plate become vertical state (in conjunction with Figure 12) and drive mah-jong pieces 8 to slide at chute from level via the fillet of chute 1a left end, after partial gear 2 has toothed portion and tooth bar to throw off, tooth bar 4 enters backhaul under the pulling force effect of wind spring 5, finally gently get back to original state, as shown in Figure 9.A, b, c, tetra-steps of d in contrast Figure 10, mah-jong pieces are pushed to card bearing board 12 under the effect of the Mah-jongg push plate 11 of mahjong machine, and card bearing board 12 rises mah-jong pieces 8 is delivered to desktop 13.
Random Factor Mahjong rule is different, mah-jong pieces specification also has difference, by adjusting the hole slot matching relationship between tooth bar head 4a and tooth bar body 4b, can ensure that the mah-jong pieces 8 of different length can finally arrive by mah-jong pushing device provided by the invention the middle position of card bearing board 12.
