Description

Technical Field

[0001] This utility model belongs to the technical field of mahjong machines, and in particular relates to a card-pushing component and a mahjong machine. Background Technology

[0002] The working principle of a mahjong machine is that the mahjong tiles with their backs facing up are attracted by the magnetic ring on the shuffling drum, rotate with the magnetic ring and are sent to the conveyor trough, where they are pushed into a pile by the stacking motor at the machine head and pushed away by the chain rod. The tiles with their fronts not being magnetic continue to rotate on the plate (single-port machine principle), which has now been upgraded to a four-port machine.

[0003] A search revealed that application number 202323047159.2 discloses a tile-pushing component in a mahjong machine's lifting mechanism, which "includes a fixed frame, a tile-pushing component for pushing mahjong tiles, a rotating shaft rotatably connected to the fixed frame, a swing rod fixed to the rotating shaft, and a drive component for driving the rotating shaft to rotate periodically. The drive component is installed on the fixed frame, the rotation axis of the rotating shaft is a first axis, and the swing rod is hinged to the tile-pushing component with the hinge axis being a second axis." This design has the technical effect of "preventing the tile-pushing component from rotating and keeping the upper and lower layers of tiles flush."

[0004] Firstly, the two "swing rods" and the "push card bracket" in this mechanism are independently connected. Because the hinges cannot fit completely, the "push card component" will swing left and right during operation. At the same time, since the upper end of the "connecting rod" is connected to the "push card component" at a single point, the swinging will be aggravated, resulting in large and uneven gaps after the mahjong tiles are pushed out. Secondly, the connecting seats of the "rotating shaft" and the "connecting rod" are fixed to the "fixed frame" by threads, which makes assembly and maintenance inconvenient.

[0005] To address the aforementioned problems, this application proposes a card-pushing component and a mahjong machine. Utility Model Content

[0006] The purpose of this utility model is to provide a card-pushing component and a mahjong machine, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a card-pushing assembly, comprising a fixed frame and a card-pushing component. The card-pushing component includes a card-pushing plate and a card-pushing bracket. A swing rod is rotatably connected to the fixed frame via a rotating shaft, and a connecting rod is also rotatably connected to the fixed frame. The upper ends of the swing rod and the connecting rod are hinged to the card-pushing bracket. The card-pushing component reciprocates under the action of a driving assembly, the rotating shaft, the swing rod, the connecting rod, and a torsion spring. A crossbeam is erected between the two swing rods. The crossbeam and the rotating shaft are both cylindrical metal components with the same diameter. The crossbeam is fixed to the end of the swing rod away from the rotating shaft and is distributed parallel to the rotating shaft. A horizontal push rod is fixed to the upper end of the connecting rod. At least one set of symmetrical hinge points are provided between the push rod and the card-pushing bracket.

[0009] Furthermore, the two ends of the rotating shaft are fitted with first bearing seats to abut the two ends of the torsion spring between the fixed frame and the rotating shaft. The first bearing seats are hinged to the rotating shaft and engaged with the fixed frame.

[0010] Furthermore, the upper and lower ends of the swing arm are respectively provided with through holes for the insertion of the pivot and the crossbeam. The swing arm is welded and fixed to the pivot and the crossbeam after insertion.

[0011] Furthermore, the top of the swing arm is also provided with a through hole that is hinged to the pusher bracket and connected by a pin.

[0012] Furthermore, a second bearing is hinged to the lower end of the connecting rod, and the second bearing is engaged with the fixing frame. An arc-shaped bearing is formed at the bottom of the pusher bracket, and a bearing cover is engaged at the bottom of the arc-shaped bearing. When the bearing cover is engaged with the arc-shaped bearing, a shaft hole for the pusher to rotate is formed.

[0013] Furthermore, the push rod and the connecting rod are perpendicularly distributed, and the connecting rod is located at the midpoint of the second bearing seat.

[0014] Furthermore, the fixing frame has an integrally formed U-shaped seat for the rotating shaft.

[0015] This utility model also provides a mahjong machine, including the aforementioned card-pushing assembly. The fixing frame is fixedly installed in the mahjong machine, and the card-pushing component pushes the cards under the coordinated action of the drive assembly, rotating shaft, swing rod, and connecting rod.

[0016] This utility model has the following beneficial effects:

[0017] This utility model involves installing a crossbeam at the upper end between two swing rods. The crossbeam and the rotating shaft form a stable integrated structure. At the same time, the upper end of the connecting rod is fixed to the push rod. The push rod increases the uniformity of power transmission, thereby avoiding left and right swaying when the card pusher pushes the cards, and making the mahjong cards more neat.

[0018] In this invention, the crossbeam and the pivot shaft have the same diameter, eliminating the need for additional sheet metal parts procurement costs. At the same time, it simplifies the processing steps, thereby controlling costs while enhancing the overall structural reliability.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1-4 As shown, this utility model is a card-pushing assembly, including a fixed frame 1 and a card-pushing component 2. The card-pushing component 2 includes a card-pushing plate 21 and a card-pushing bracket 22. A swing rod 5 is rotatably connected to the fixed frame 1 via a rotating shaft 4. A connecting rod 6 is also rotatably connected to the fixed frame 1. The upper ends of the swing rod 5 and the connecting rod 6 are hinged to the card-pushing bracket 22. The card-pushing component 2 reciprocates under the action of the driving assembly 3 and the rotating shaft 4, the swing rod 5, the connecting rod 6, and the torsion spring 42. In this embodiment, after the motor 31 works, it drives the driving gear 32 to mesh with the driven gear 33. The driven gear 33 drives the cam 34 to rotate. The elastic force of the torsion spring 42 always swings the card-pushing component 2, the swing rod 5, and the connecting rod 6 outward. After the cam 34 rotates, it contacts the roller 35. Under the action of the cam 34, the card-pushing component 2, the swing rod 5, and the connecting rod 6 are pushed inward. Under the action of the torsion spring 42, the roller 35 always rolls in contact with the irregular surface of the cam 34, thereby driving the card-pushing component 2 to reciprocate.

[0030] A crossbeam 51 is installed between the two swing rods 5. Both the crossbeam 51 and the pivot 4 are cylindrical metal components with the same diameter. During processing, no additional sheet metal parts need to be purchased, and the cylindrical rods themselves do not require sheet metal processing. The crossbeam 51 is fixed to the end of the swing rod 5 away from the pivot 4 and is distributed parallel to the pivot 4. The parallel arrangement standardizes the overall structure and provides stability. The upper and lower ends of the swing rod 5 are respectively provided with through holes for the pivot 4 and the crossbeam 51 to be inserted. The swing rod 5, pivot 4, and crossbeam 51 are welded and fixed after insertion. The through holes and the cylindrical rods are used for positioning before welding, reducing the difficulty of welding. After actual welding, the weld points need to be ground to ensure quality. The top of the swing rod 5 is also provided with a through hole that is hinged to the pusher bracket 22 and connected by a pin. The pin passes through the connection hole between the top of the swing rod 5 and the pusher bracket 22, forming a hinge between the pusher 2 and the pusher bracket 22. To avoid abnormal noise and unnecessary wear, lubricant can be applied to the hinge.

[0031] A horizontal push rod 62 is fixed at the upper end of the connecting rod 6. At least one set of symmetrical hinge points are provided between the push rod 62 and the push plate bracket 22. The push rod 62 and the connecting rod 6 are vertically distributed, and the connecting rod 6 is located at the midpoint of the second bearing 61. In this embodiment, the hinge points are formed by the bearing cover 63 and the arc-shaped bearing 221. The vertical and symmetrical structures are used to ensure that the thrust is transmitted evenly and that the push plate component 2 moves more smoothly.

[0032] The first bearing seat 41 is fitted at both ends of the rotating shaft 4, and the two ends of the torsion spring 42 are pressed against the fixed frame 1 and the rotating shaft 4. The torsion spring 42 has a spiral structure in the middle and abutting rods at both ends. One rod abuts against the fixed frame 1, and the other rod can be directly fixed to the rotating shaft 4 or abutted against the swing rod 5 to form an elastic hinge.

[0033] The lower end of the connecting rod 6 is hinged to a second bearing 61, which engages with the fixed frame 1. The bottom of the push bracket 22 has an arc-shaped bearing 221, which engages with a shaft cover 63. When the shaft cover 63 engages with the arc-shaped bearing 221, a shaft hole for the push rod 62 to rotate is formed. This shaft hole is formed by splicing two arc-shaped grooves, which are respectively formed in the arc-shaped bearing 221 and the shaft cover 63. In this embodiment, the engagement between the first bearing 41 and the second bearing 61 and the fixed frame 1 is achieved by using ordinary elastic elements and locking blocks and slots. After engagement, the first bearing 41 is in close contact with the fixed frame 1, and the shaft cover 63 is in close contact with the arc-shaped bearing 221. It also has a disassembly function. Both engagement and disassembly are conventional mechanical methods, which will not be described in detail here. Similarly, to avoid abnormal noise and wear at the hinge, lubricating oil can be applied appropriately.

[0034] The fixed frame 1 has an integrally formed U-shaped seat 11 for the rotating shaft 4. The U-shaped seat 11 prevents the rotating shaft 4 from bending and deforming, and at the same time plays a role in strengthening the structural stability.

[0035] This utility model also provides a mahjong machine, including the above-mentioned card-pushing assembly. The fixing frame 1 is fixedly installed in the mahjong machine, and the card-pushing component 2 pushes the cards under the cooperation of the drive assembly 3, the rotating shaft 4, the swing rod 5, and the connecting rod 6.

[0036] Understandably, this utility model forms an integrated and stable structure by installing a crossbeam with the same diameter as the pivot at the top of the two swing arms, which effectively suppresses the left and right swaying of the pusher and improves the neatness of the mahjong tiles. At the same time, the fixed design of the upper end of the connecting rod and the push rod enhances the uniformity of power transmission, further improving the neatness of the mahjong tiles. By standardizing the specifications of the crossbeam and pivot, the additional sheet metal parts procurement cost is saved and the processing steps are simplified, which significantly improves the reliability of the equipment structure while optimizing production costs.

[0037] A specific application of this embodiment is as follows: the upper and lower ends of the swing rod 5 are open and are inserted into the rotating shaft 4 and the crossbeam 51, forming the required structure without the aid of a positioning fixture. Then, the insertion connection is welded and fixed to form an integral structure. The two ends of the rotating shaft 4 are successively fitted with torsion springs 42 and first bearing seats 41. The first bearing seats 41 are inserted and snapped into the fixing frame 1. The upper and lower ends of the connecting rod 6 are provided with through holes. The second bearing seat 61 is inserted into the lower end hole of the connecting rod 6 to form a rotatable connection. Then, the second bearing seat 61 is inserted and snapped into the fixing frame 1. The push rod 62 passes through the through hole at the upper end of the connecting rod 6 and is welded and fixed. The push rod 62 is placed in 223. The shaft cover 63 is snapped into 223 to rotatably connect the push rod 62 to the bottom of the push card bracket 22. The upper ends of the two swing rods 5 are rotatably connected to the push card bracket 22 through the shaft pin.

[0038] During operation, the drive assembly 3 drives the connecting rod 6. The bottom of the connecting rod 6 rotates on the fixed frame 1, and the upper end drives the card pusher 2 to swing. At this time, the swing arm 5 swings along with it, and the rotating shaft 4 rotates along with it on the first shaft seat 41. With the cooperation of the cam 34, the roller 35 and the torsion spring 42, the card pusher 2 is driven to swing back and forth, thereby performing the card pushing work.
