The operation panel limiting unit includes an adjustment limiting sleeve 24, the adjustment limiting sleeve 24 is in a cone frustum shape, the inner surface is provided with an internal thread, and the first external thread 81 is connected with the internal thread. The upper end of the vertical pipe 22 passes through the fixed seat 108 and then is positioned above the fixed seat 108, so that the operation panel 21 is positioned above the adjusting and limiting sleeve 24, and when the operation panel 21 descends under the action of the lifting driving unit, the top end of the adjusting and limiting sleeve 24 can contact the bottom end of the operation panel 21, and the position of the operation panel 21 during descending is limited. The height position of the top end of the adjusting stop collar 24 can be adjusted by rotating the adjusting stop collar 24, so that the high and low positions required by the descending of the operating panel 21 can be adjusted, and the specific adjustment mode is described in detail later.
Figure 7 is a diagram of a card shuffling tray configuration in accordance with an embodiment of the present invention.
As shown in fig. 7, the shuffling tray 71 includes a tray body 711, a sliding layer 712, and a plurality of stoppers 713. The tray body 711 includes a slide portion 7111, a card stopping portion 7112, and a card blocking portion 7113.
The sliding portion 7111 has a truncated conical shape similar to a bamboo hat, and is positioned below the push-in opening 1051 to receive the mahjong pieces 200 dropped from the push-in opening 1051 and slide the mahjong pieces 200 thereon. The middle part of the sliding part 7111 is used for connecting with the shuffling tray mounting unit, and is provided with a bearing seat part 7114 which is recessed downwards to form an annular groove shape, and the section of the bearing seat part 7114 is approximately L-shaped, and is provided with a side wall which extends downwards from the inner side edge of the sliding part 7111 and a bottom wall which extends inwards horizontally from the side wall.
In this embodiment, the upper surface of the sliding portion 7111 is inclined, that is, in a normal installation and use state, the height of the outer portion of the sliding portion 7111 is lower than the height of the inner portion, and the angle of inclination is 30 °. When the mahjong pieces 200 are pushed in from the pushing opening 1051, the mahjong pieces can slide downwards on the scattered sliding parts 7111, and the scattered sliding process plays a role of disturbing the mahjong pieces 200.
The stop portion 7112 is connected to the outside of the slide portion 7111, and extends outward around the slide portion 7111 in a loop shape. In this embodiment, the upper surface of the inner part (i.e., the part connected to the sliding part 7111) of the card stopping part 7112 has a small inclination, while the outer part has no inclination and is horizontal.
The guard portion 7113 is provided at an outer edge of the stop portion 7112, and extends upward from the outer edge in a loop.
The sliding layer 712 is laid on the sled portion 7111 and the discard portion 7112. The sliding layer 712 of the present embodiment is divided into a plurality of block-shaped components, including a plurality of first sliding layer portions 7121 laid on the sliding portion 7111 and a plurality of second sliding layer portions 7122 laid on the card stopping portion 7112, wherein the number of the first sliding layer portions 7121 and the number of the second sliding layer portions 7122 are the same (8 each) and correspond to each other one.
The first sliding layer portions 7121 are in a curved fan shape, each first sliding layer portion 7121 is curved toward the same side along the circumferential direction, and the shapes of the edges of the two sides of the adjacent first sliding layer portions 7121 are matched, so that gaps between the first sliding layer portions 7121 are in a plurality of spiral lines which are uniformly distributed.
The second sliding layer portion 7122 is fan-shaped, the inner edge is located at the joint of the sliding portion 7111 and the card stopping portion 7112 and corresponds to the outer edge of the first sliding layer portion 7121, a certain gap is formed between the two, and the outer edge of the second sliding layer portion 7122 extends to the card stopping portion 7113 and contacts with the card stopping portion 7113.
The first sliding layer portion 7121 and the second sliding layer portion 7122 are made of composite fiber material fabrics, and in this embodiment, are made of a wool surface layer of a nylon fastening tape.
The number of the stoppers 713 is 8, and they are uniformly distributed on the outer portion of the card stopping portion 7112 in the circumferential direction. The 8 baffle blocks 713 of the present embodiment are respectively located between the gaps of the two adjacent second sliding layer portions 7122, and the two side edge portions of each second sliding layer portion 7122 are further provided with notches corresponding to the baffle blocks 713, so that the baffle blocks 713 are exposed. Each baffle 713 is a cowhell block, that is, is made of rubber or plastic material with certain elasticity, and can block the mahjong tile 200 so as to shuffle the mahjong tile, and can reduce collision noise.
As shown in fig. 4-5, the shuffler plate mounting unit includes a bearing 721 and a retaining cap 722.
The bearing 721 is sleeved in the middle of the mounting seat 108, the inner ring of the bearing 721 is matched with the outer surface of the mounting seat 108 in an interference fit manner, and the outer ring of the bearing 721 is matched with the inner surface of the bearing seat 7114 in an interference fit manner. Thus, the shuffling tray 71 is rotatably mounted to the mounting base 108 by means of bearings 721.
The fixing cap 722 is substantially in the form of a hollow truncated cone, is positioned above the shuffling tray 71, and is mounted on the mounting seat 108 by being screwed with the second male screw portion 82. The lower surface of the fixing cap 722 abuts against the upper surface of the inner ring of the bearing 721, so that the bearing 721 is pressed into the bearing seat 722 and is not easily loosened. In addition, in this embodiment, the pressing rotation direction of the fixing cap 722 (i.e. the rotation direction of the downward movement) is the same as the rotation direction of the shuffling tray 71, so even if a certain driving force is generated by the contact between the shuffling tray 71 and the fixing cap 722 when the shuffling tray 71 rotates, the force can also cause the fixing cap 722 to generate a downward pressing rotation movement trend, so that the fixing cap 722 can keep a pressing state during use, and the loosening is avoided.
Fig. 8 is an enlarged view of a portion a of fig. 4.
As shown in fig. 8, the lower end of the adjusting stop collar 24 is provided with a circle of extending parts 241 extending vertically downwards, and the fixing cap 722 is provided with a receiving groove 7221 for receiving the extending parts 241 therein. Specifically, the outer wall of the receiving groove 7221 is higher in height, formed around the periphery of the extension portion 241, and the inner wall is lower in height, and the inner surface of the inner wall is an internal thread for screw-coupling with the second screw portion 82.
Fig. 9 is an exploded view of the mounting base, the adjusting stop collar, and the fixing cap according to the embodiment of the present invention.
As shown in fig. 8-9, in this embodiment, a plurality of engaging ribs 242 extending longitudinally along the surface are uniformly distributed on the outer surface of the adjusting stop collar 24, and these engaging ribs 242 all extend onto the extending portion 241.
Fig. 10 is a view showing a structure of a fixing cap according to an embodiment of the present invention.
As shown in fig. 8-10, a recess 7220 is formed at the upper end of the outer wall of the receiving groove 7221, an elastic piece 7222 is connected in the recess 7220, and a protrusion is formed on the inner side surface (i.e., the surface facing the adjusting stop collar 24) of the elastic piece 7222, and a plurality of engaging grooves 7223 extending substantially longitudinally are formed on the protrusion. The engaging grooves 7223 are matched in size and pitch to the engaging protrusions 242 in size and pitch between adjacent engaging grooves 7223, and thus can be engaged with the engaging protrusions 242. Since the fixing cap 722 is made of plastic or other materials, the elastic piece 7222 has certain elasticity, and can apply certain pressure to the clamping groove 7223, so that the clamping groove 7223 and the clamping convex strip 242 keep an engaged state when not subjected to external force, namely, the clamping groove 7223 and the clamping convex strip are elastically clamped, and an elastic clamping structure is formed. Thus, when no external force is applied, the relative rotation between the fixing cap 722 and the adjusting and limiting sleeve 24 in the circumferential direction is limited by the engagement action of the fixing cap 722 and the adjusting and limiting sleeve 24, i.e., the relative rotation cannot occur between the fixing cap 722 and the adjusting and limiting sleeve 24.
When the operator (i.e., a person who performs installation or maintenance of the mahjong machine 100) needs to further install the fixing cap 722 and the adjusting and limiting sleeve 24 in a state that the bearing 721 and the shuffling tray 71 are mounted on the mounting base 108, the fixing cap 722 may be first screwed on the second external screw portion 82 and tightened to press the inner ring of the bearing 721, then the adjusting and limiting sleeve 24 may be screwed on the first external screw portion 81, and the adjusting and limiting sleeve 24 may be rotated according to a desired position when the operation panel 21 is lowered and then stopped at a proper height position.
In the installation process or the height position adjustment process of the adjusting stop collar 24, when an operator rotates the adjusting stop collar 24, the clamping groove 7223 and the clamping convex strip 242 can be separated due to the fact that the force applied by the operator can overcome the elastic force action of the elastic piece 7222, so that the adjusting stop collar 24 can rotate relative to the fixing cap 722, and when the operator does not rotate the adjusting stop collar 24 any more, the elastic force action of the elastic piece 7222 applies pressure to the clamping groove 7223 to enable the elastic piece 7223 and the clamping convex strip 242 to return to the meshed state, and relative rotation of the fixing cap 722 and the adjusting stop collar 24 is limited.
Thus, an operator can conveniently adjust the height position of the adjusting stop collar 24, and at the same time, the adjusting stop collar 24 cannot rotate relative to the fixing cap 722 during normal use.
In addition, since the fixing cap 722 always has a rotating and pressing trend under the action of the shuffling tray 71, the fixing cap 722 basically does not rotate in the actual use process, and accordingly the adjusting stop collar 24 does not rotate, so that the upper end position of the adjusting stop collar 24 can be kept unchanged. In addition, in the present embodiment, the outer surface of the fixing cap 722 is also provided with a plurality of protruding strips, which can increase the surface friction force and facilitate the screwing action of the operator, and meanwhile, the engaging protruding strips 242 extend to the inclined portion of the adjusting stop collar 24, which can also increase the surface friction force and facilitate the screwing action.
The shuffling tray drive unit includes a shuffling motor 731, a shuffling output gear 732, a shuffling input gear ring 733, and an auxiliary gear 734.
The shuffling motor 731 is fixedly mounted below the supporting plate 1061, and its output shaft passes upward through the supporting plate 1061.
A shuffling output gear 732 is mounted on the output of the shuffling motor 731, below the shuffling tray 71.
As shown in fig. 4, the lower surface of the slide 7111 is provided with a ring gear, that is, a shuffle input ring gear 733. The shuffle output ring gear 733 is annularly distributed around the bearing housing portion 7114. The shuffling output gear 732 is meshed with the shuffling input ring gear 733 so that the shuffling motor 731 can drive the shuffling tray 71 in rotation by the meshed relationship of the two.
The number of auxiliary gears 734 in this embodiment is two, each mounted on the table base 106 by a gear mount. The gear mount has a rotational shaft on which an auxiliary gear 734 is rotatably mounted and meshes with the shuffle input ring gear 733. The two auxiliary gears 734 and the shuffling output gears 732 are circumferentially arranged at equal intervals (i.e., spaced apart from each other by 120 °), and the rotation process of the shuffling tray 71 can be made smoother by the meshing action of the two auxiliary gears 734 and the shuffling input ring gear 733.
As shown in fig. 5, a plurality of deck height adjustment units 74 are uniformly distributed circumferentially below the card stopping portion 712.
Fig. 11 is a structural view of the card shuffling tray height adjustment unit of this embodiment.
As shown in fig. 11, the deck height adjustment unit 74 includes a height adjustment seat 741 and a scroll wheel 742.
The height adjustment seat 741 is fixed to the support plate 1061 and has a pair of seat plates 7411 spaced apart. Three height adjustment grooves 7412 having the same width but sequentially decreasing depths are provided on the inner side surface of each seat plate 7411 (i.e., the side surface facing the other seat plate 7411), the height adjustment grooves 7412 on the two seat plates 7411 are disposed opposite to each other, and the depths of the height adjustment grooves 7412 on the two seat plates 7411 are the same.
The rolling wheel 742 has a wheel body 7411 and an axle 7412 disposed on the wheel body 7412, wherein the diameter of the axle 7412 is adapted to the width of the height adjustment slot 7412, and the distance between two ends of the axle 7412 is adapted to the distance between two opposite height adjustment slots 7412, so that the wheel body 7412 can be placed in the two opposite height adjustment slots 7412 respectively, thereby being located between the two seat plates 7411.
The wheel 7421 contacts the lower surface of the tray body 711 and supports the card stopping portion 712 during rotation of the shuffling tray 71. Since the card stopping part 712 is spaced from the bearing part 714, when a large number of mahjong pieces 200 are stacked on the card stopping part 712, the mahjong pieces are easily sunk due to the bearing, and the support effect of the wheel body 7421 can prevent the sunk phenomenon, so that the mahjong pieces 200 on the card stopping part 712 can be sucked more easily by the card feeding mechanism 101. When the wheel shafts 7422 are placed in the height adjusting grooves 7412 with different depths, the heights of the wheels 7421 for supporting the card stopping part 712 are different, and the height of the card stopping part 712 can be slightly raised or lowered, so that the supporting heights can be adjusted by matching with mahjong pieces 200 with different specifications, and further, the suction action of the card feeding mechanism 101 is easier to realize.
The mahjong machine 100 of the embodiment can be used by four users simultaneously, and is correspondingly provided with four card feeding mechanisms 101 which are respectively positioned at four corner positions of a table base 106. Each tile feeding mechanism 101 can absorb the mahjong tiles 200 from the tile stopping portion 7112, stack the mahjong tiles and lift the stacked mahjong tiles 200 to the table top for a user to use, and the specific structure and the working principle thereof can adopt the prior art and are not described herein again.
Example operation and Effect
According to the operation panel and shuffling integrated system and mahjong machine provided by the embodiment, as the installation seat 108 is provided with the first threaded part 81 and the second threaded part 82, the adjusting limiting sleeve 24 is in threaded connection with the first threaded part, the fixing cap 722 is in threaded connection with the second threaded part 82, and an elastic clamping structure is arranged between the adjusting limiting sleeve 24 and the fixing cap 722, when the adjusting limiting sleeve 24 is not subjected to external force, the adjusting limiting sleeve 24 is not easy to rotate, when the adjusting limiting sleeve is subjected to external force, the adjusting limiting sleeve 24 can rotate relatively, so that the position of the adjusting limiting sleeve 24 can be adjusted, on one hand, the height position of the adjusting limiting sleeve 24 can be kept during normal use, the descending position of the control panel 1021 cannot be changed, on the other hand, the adjusting limiting sleeve 24 can rotate only by screwing the adjusting limiting sleeve 24 to overcome the elastic force, so that the elastic clamping structure can be disconnected, and the high and low adjustment of the descending position of the control panel 1021 can be realized completely without dismantling the control panel 1021, and therefore the installation and maintenance are very easy to realize.
In the embodiment, since the screw directions of the first screw portion 81 and the second screw portion 82 are opposite, the above elastic engagement structure does not cause the adjustment stop collar 24 and the fixing cap 722 to rotate together, so that the adjustment stop collar and the fixing cap are loosened together. In addition, since the pressing rotation direction of the fixing cap 722 is the same as the rotation direction of the shuffling tray 71, the force generated by the contact with the fixing cap 722 when the shuffling tray 71 rotates can keep the fixing cap 722 in a pressed state during use, and further, the loosening is avoided.
In the embodiment, since the engaging protrusion 242 is disposed on the extending portion 241 of the adjusting stop collar 24, the elastic piece 7222 is disposed on the accommodating groove 7221 accommodating the extending portion 241, and the engaging groove 7223 and the engaging protrusion 242 on the elastic piece 7222 together form an elastic engaging structure, the elastic engaging can be realized without providing additional elastic components, and the manufacturing and assembling are easier.
It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made in the technical solution without departing from the spirit and scope of the invention, which is defined in the claims.
For example, in the embodiment, the engaging protrusion 242 on the extension portion 241 of the adjusting stop collar 24 and the engaging groove 7223 connected to the elastic piece 7222 of the accommodating groove 7221 together form an elastic engaging structure. Alternatively, the installation positions of the engaging protrusions 242 and the elastic pieces 7222 may be changed, that is, the extending portion 241 may be provided with a recess and connected to the elastic pieces 7222, and the engaging protrusions 242 may be provided on the inner surface of the outer wall of the accommodating groove 7221, so long as the engaging grooves 7223 on the elastic pieces 7222 and the engaging protrusions 242 may be provided opposite to each other and engaged with each other.
As a further alternative, the resilient snap structure may take other forms. For example, a clamping groove is provided on one of the extension portion 241 and the accommodating groove 7221, and a clamping block with a spring is fixedly provided on the other, which can also play a role of mutually clamping when no external force is applied, not clamping when external force is applied, and enabling relative rotation between the adjusting stop collar 24 and the fixing cap 722.
In addition, in the embodiment, the first thread portion 81 and the second thread portion 82 have opposite thread directions, and are not easy to be loosened together. However, in the case where the pressing rotation direction of the fixing cap 722 is the same as the rotation direction of the shuffling tray 71, the screw directions of the first screw portion 81 and the second screw portion 82 may be set to be the same, and in this case, since the fixing cap 722 is pressed against the bearing 721 and is not easily rotated, the adjustment stopper 24 is also not easily rotated by the elastic engagement.
