Description

Technical Field

[0001] The utility model relates to the technical field of mahjong machines, in particular to a card pushing mechanism of a mahjong machine. Background Art

[0002] The card pusher mechanism is a vital component of the mahjong machine. It is responsible for pushing the mahjong tiles accurately and efficiently. When the mahjong machine starts working, the card pusher mechanism will operate under the carefully designed mechanical logic. First, through the coordinated action of the motor and a series of sensors, the card pusher mechanism ensures that it is reset to the initial position to prepare for the next card push action. Once the reset is completed, the card pusher will start to act according to the preset program.

[0003] like Figure 5 As shown, the existing card pushing mechanism is that a cam is driven by a motor to rotate, and the cam contacts the bearing on the rocker, driving the rocker to rotate, and the rocker drives the shaft to rotate, and the shaft drives the rocker arm and the movable plate to slide on the guide rail, thereby realizing the card pushing plate (the card pushing plate is fixed on the movable plate, not shown in the figure).

[0004] However, the card pushing mechanism described above has the following technical problems during use: since only the middle part of the card pushing plate is fixed to the movable plate, the fixed contact range is small, and the two ends of the card pushing plate are unstable and easy to shake during the card loading process, which may cause flash disconnection during use and has a short service life. Summary of the invention

[0005] The main purpose of the utility model is to overcome the deficiencies in the prior art and provide a card pushing mechanism for a mahjong machine.

[0006] The utility model adopts the following technical scheme to achieve its technical purpose: a mahjong machine card pushing mechanism, comprising a plate frame, one side of the plate frame is rotatably connected to a shaft rod, both ends of the shaft rod are fixedly connected to a main push rod, one side of the main push rod is provided with a limit push rod, and the limit push rod is rotatably connected to one side of the plate frame;

[0007] One end of the main push rod and the limit push rod is fixedly connected to a push plate via a concave plate;

[0008] One end of the main push rod is rotatably connected to one end of the concave plate, and one end of the limit push rod is slidably connected inside the other end of the concave plate;

[0009] The shaft rod rotates to drive the main push rod and the limit push rod to rotate, and the main push rod and the limit push rod push the card pushing plate to push the card horizontally.

[0010] Preferably, one end of the limit push rod is fixedly connected to a slider, and the slider is slidably connected in a slide groove of the limit plate integrally connected to the other end of the concave plate;

[0011] The slider and the slide groove are both configured as arc structures;

[0012] During the process of the main push rod and the limit push rod pushing the card pushing plate to load the card, the pushing trajectory of the main push rod and the limit push rod is restricted by setting the slider and the slide groove to ensure that the card pushing plate can be pushed flatly to load the card.

[0013] Preferably, a through groove corresponding to the position of the main push rod and the limit push rod is opened inside the plate frame, and the main push rod and the limit push rod are driven by the rotation of the shaft rod to rotate into the through groove. The through groove can make the rotation trajectory of the main push rod and the limit push rod outside the plate frame smaller, thereby reducing space occupancy and rationally utilizing the internal space of the plate frame.

[0014] Preferably, a torsion spring is fixedly installed at the connection between the main push rod and the shaft rod, which enables the shaft rod, main push rod and limit push rod to automatically reset after being rotated by external force, so as to facilitate the next rotation of the shaft rod, main push rod and limit push rod to perform the card loading action.

[0015] Preferably, a rocker is fixedly connected to the outer wall of the shaft rod, a bearing is fixed to one end of the rocker rod, a cam is arranged on one side of the bearing, and the cam is rotatably connected to one side of the plate frame;

[0016] The cam is driven to rotate by a motor fixed on one side of the plate frame, and the cam contacts the bearing to drive the rocker to rotate.

[0017] Preferably, a driving gear and a driven gear are rotatably provided on the other side of the plate frame, and the two are kept in meshing connection, the driving gear is driven to rotate by a motor, and the driven gear is fixed to the cam and rotates synchronously.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The card pushing mechanism of the mahjong machine is fixed at the two ends of the card pushing plate by setting the main push rod, the limit push rod and the concave plate, etc., which increases the fixing and force range of the card pushing plate, makes the overall support force more uniform, effectively improves the stability of the card pushing plate during use, avoids the problem of easy flash breakage at both ends of the card pushing plate, and prolongs the service life of the card pushing plate. In addition, by setting the main push rod fixed at both ends of the card pushing plate, and setting the limit push rod, the slider and the slide groove to limit the pushing track of the card pushing plate, it is ensured that the card pushing plate is pushed flat to load the cards, so that the card pushing plate has a normal card loading function.

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model.

[0030] See also Figure 1-5 A mahjong machine card pushing mechanism includes a plate frame 1, one side of the plate frame 1 is rotatably connected to a shaft rod 2, both ends of the shaft rod 2 are fixedly connected to a main push rod 6, one side of the main push rod 6 is provided with a limit push rod 7, and the limit push rod 7 is rotatably connected to one side of the plate frame 1;

[0031] One end of the main push rod 6 and the limit push rod 7 is fixedly connected to a push plate 11 through a concave plate 8;

[0032] One end of the main push rod 6 is rotatably connected to one end of the concave plate 8, and one end of the limit push rod 7 is slidably connected inside the other end of the concave plate 8;

[0033] Specific as Figure 2 As shown, one end of the limit push rod 7 is fixedly connected with a slider 9, and the slider 9 is slidably connected in the slide groove 1001 of the limit plate 10 integrally connected to the other end of the concave plate 8, and the slider 9 and the slide groove 1001 are both arranged in an arc structure; in the process of the main push rod 6 and the limit push rod 7 pushing the card pushing plate 11 to put cards, the setting of the slider 9 and the slide groove 1001 limits the pushing trajectory of the main push rod 6 and the limit push rod 7 to ensure that the card pushing plate 11 is pushed flatly to put cards;

[0034] Specific as Figure 1-3 As shown, the shaft 2 rotates to drive the main push rod 6 and the limit push rod 7 to rotate, and the main push rod 6 and the limit push rod 7 push the card pushing plate 11 to push the cards horizontally.

[0035] Furthermore, specifically Figure 3 As shown, a through groove 101 corresponding to the position of the main push rod 6 and the limit push rod 7 is opened inside the plate frame 1. The shaft rod 2 is rotated to drive the main push rod 6 and the limit push rod 7 to rotate into the through groove 101. The through groove 101 can make the rotation trajectory of the main push rod 6 and the limit push rod 7 outside the plate frame 1 smaller, reduce space occupancy, and reasonably utilize the internal space of the plate frame 1.

[0036] Furthermore, specifically Figure 1 As shown, a torsion spring 5 is fixedly installed at the connection between the main push rod 6 and the shaft rod 2. The torsion spring 5 enables the shaft rod 2, the main push rod 6 and the limit push rod 7 to automatically reset after being rotated by an external force, so as to facilitate the next rotation of the shaft rod 2, the main push rod 6 and the limit push rod 7 to perform the card loading action.

[0037] Furthermore, Figure 1 , 4 As shown, the outer wall of the shaft 2 is fixedly connected to a rocker 201, a bearing is fixed to one end of the rocker 201, a cam 4 is arranged on one side of the bearing, and the cam 4 is rotatably connected to one side of the plate frame 1; the cam 4 is driven to rotate by a motor 3 fixed on one side of the plate frame 1, and the cam 4 contacts with the bearing, driving the rocker 201 to rotate.

[0038] A driving gear 12 and a driven gear 13 are rotatably provided on the other side of the plate frame 1, and the two are kept in meshing connection. The driving gear 12 is driven to rotate by the motor 3, and the driven gear 13 is fixed with the cam 4 and rotates synchronously.

[0039] Specifically, when in use, the cam 4 is driven to rotate by the motor 3, and the cam 4 contacts with the bearing, driving the rocker 201 to rotate, and the rocker 201 drives the shaft 2 to rotate, so that the main push rod 6 performs a card pushing action, and the main push rod 6 drives the limit push rod 7 to rotate through the concave plate 8, and at the same time, the push trajectory of the card pushing plate 11 is limited by the limit push rod 7, the slider 9 and the slide groove 1001, so as to avoid the card pushing plate 11 from tilting during the card pushing process, and ensure that the card pushing plate 11 is pushed flatly to push the card onto the card;

[0040] After the card is pushed horizontally, the cam 4 has rotated a certain angle, and the cam 4 is no longer in contact with the bearing on the rocker 201. Under the action of the torsion spring 5, the shaft rod 2, the main push rod 6 and the limit push rod 7 can be automatically reset, so that the cam 4 will contact the bearing on the rocker 201 next time, driving the shaft rod 2, the main push rod 6 and the limit push rod 7 to rotate to perform the card loading action.

[0041] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structures, equivalent processes or equivalent functional transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of protection of the utility model patent.
