[0001] This utility model relates to an entertainment facility, and more particularly to a card machine. Background Technology

[0002] Automatic card dealing machines, as a common entertainment facility, generally have an automatic card-rotating function. To ensure the stability of the card-rotating operation, existing card dealing machines are equipped with corresponding rotation buffer mechanisms to dampen shocks when the machine starts or stops rotating.

[0003] The rotary buffer mechanism in existing card dealing machines is generally located between the rotary pulley and the base. For example, the patent application document CN118304638 A, entitled "A Rotary Card Dealer", provides a rotary buffer mechanism. Although it can play a certain role in rotary buffering, it acts directly on the rotary transmission part of the card dealing machine. The vibration generated during the buffering process will inevitably affect the rotary transmission function. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art of card machines by providing a card machine base and a card machine.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: The card machine base includes a base body, on which a support leg assembly is provided. The support leg assembly includes a support leg mounted on the base body. The support leg and the base body have a mating stroke in the rotational direction about the center line of the base body. The support leg assembly also includes a buffer assembly for realizing indirect contact between the support leg and the base body. The buffer assembly is used to provide resistance when the support leg and the base body move relative to each other at the mating stroke.

[0006] The main body of the card machine rotates on the base. During start-up and shutdown, the rotational impact force is transmitted to the base, which absorbs the energy through a buffer component, reducing mechanical vibration and noise, and improving the stability and service life of the rotating mechanism.

[0007] Preferably, the buffer assembly includes two buffer springs disposed on the base body and respectively pressed against both sides of the support leg, and two damping elements disposed between the base body and the support leg.

[0008] Preferably, the base body is provided with a support foot mounting position. The support foot mounting position includes a mating groove arranged in the rotation direction around the center line of the base body. The support foot includes a mating part located in the mating groove. The length of the mating part is less than the length of the mating groove, and the movement stroke of the mating part in the mating groove constitutes the mating stroke.

[0009] Preferably, the mating part is provided with a column, and the support foot mounting position is provided with two spring mounting seats located above the mating groove and distributed on both sides of the column. The spring mounting seats are formed with spring mounting grooves facing the column opening. Two buffer springs are respectively set in the two spring mounting grooves and their ends extend out of the spring mounting grooves and abut against the side of the column.

[0010] Preferably, a foot mounting plate is installed on the upper surface of the column, which can overlap the upper surface of the spring mounting base. The foot mounting plate facilitates the installation of the foot assembly on the base body.

[0011] Preferably, the base body includes a base plate and an annular sidewall. A mating groove is open at its lower end and located on the lower surface of the base plate. The mating groove contains a mating hole for the column to pass through. A mating distance corresponding to the mating stroke is maintained between the mating hole and the column. A spring mounting seat is fixed to the upper surface of the base plate. This mating distance allows the column to have a certain buffer stroke under the action of the buffer spring, thus providing a cushioning effect on the support legs.

[0012] Preferably, the lower end face of the top plate of the groove is provided with a damping element locking groove, the damping element is locked in the damping element locking groove and the lower part of the damping element is pressed against the upper end face of the support leg. The upper and lower sides of the damping element are pressed against the base body and the support leg respectively, which plays a corresponding motion damping role.

[0013] Preferably, a guide groove is provided on the upper surface of the mating part. The length direction of both the damping element locking groove and the guide groove is consistent with the length direction of the mating groove. The damping element is disposed between the damping element locking groove and the lower guide groove, with both ends of the damping element abutting against the two ends of the damping element locking groove along its length. The upper and lower guide grooves provide guidance for the movement of the damping element, ensuring stability during small-range relative movements between the base assembly and the support leg assembly.

[0014] Preferably, the support leg includes a plate-shaped support base, with a plate-shaped mating part disposed on the upper surface of the support base, and an elastic anti-slip pad installed on the lower surface of the support base.

[0015] Card machine, which includes the aforementioned card machine base.

[0016] This utility model, by adopting the above technical solution, has significant technical effects: This utility model, by setting a buffer component on the base support, can not only play a better role in shock absorption and energy absorption during the rotation start and stop process, but also avoid interference with the internal transmission components of the card machine. It has the characteristics of reasonable positioning and stable operation. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] Example 1 In this embodiment 1, a card machine, such as Figures 1-5 As shown, it includes a card machine base and a card machine body 2 that can rotate on the card machine base.

[0031] The card machine base includes a base body 1, on which multiple support leg components 3 are provided. The base body 1 is disc-shaped and has multiple support leg components 3 evenly spaced along the circumference of the base body 1.

[0032] In this embodiment, the base body 1 is provided with four support leg components 3. Of course, two, three or more support leg components 3 can be provided.

[0033] The support leg assembly 3 includes a support leg 301 mounted on the base body 1. The support leg 301 and the base body 1 have a mating stroke in the rotational direction about the center line of the base body 1. Specifically: In this embodiment, the support leg 301 includes an arc-shaped plate-shaped support base 309 and a mating part 302 disposed on the upper end surface of the support base 309. The support base 309 is disposed on the lower end surface of the base body 1 and located at the edge of the base body 1. The mating part 302 has the same shape as the support base 309, both being arc-shaped plates and smaller in size than the support base 309.

[0034] The base body 1 is provided with a support foot mounting position. The support foot mounting position includes a plurality of mating grooves 101 arranged in the rotation direction around the center line of the base body 1. The mating part 302 is located in the mating groove 101. The length of the mating part 302 is less than the length of the mating groove 101 and the movement stroke of the mating part 302 in the mating groove 101 constitutes the mating stroke.

[0035] The base body 1 includes a base plate 102 and an annular sidewall 103. The base plate 102 has an arc-shaped support mounting hole 104. The support mounting hole 104 has a groove top plate 105 arranged parallel to the base plate 102. The groove top plate 105 constitutes the top panel of the mating groove 101. The mating groove 101 is formed by the hole wall of the mating hole 106 and the groove bottom plate 102. The opening of the mating groove 101 is downward. The shape of the mating groove 101 is the same as the shape of the mating part 302 and the size is larger than the size of the mating part 302, so that the mating part 302 can have a movement stroke in the mating groove 101, that is, the mating stroke.

[0036] The support leg assembly 3 also includes a buffer assembly 4 for achieving indirect contact between the support leg 301 and the base body 1. The buffer assembly 4 is used to provide resistance when the support leg 301 and the base body 1 move relative to each other at the mating stroke. In this embodiment, the buffer assembly 4 includes two buffer springs 401 disposed on the base body 1 and respectively pressed against both sides of the support leg 301.

[0037] A column 303 is provided on the mating part 302. At the support foot mounting position, spring mounting seats 304 are provided above the mating groove 101 and distributed on both sides of the column 303. There are two spring mounting seats 304, each with a spring mounting groove 305 opening towards the column 303. Two buffer springs 401 are respectively disposed within the two spring mounting grooves 305, with their ends extending out of the grooves and abutting against the side of the column 303. A support foot mounting plate 306 is mounted on the upper surface of the column 303, and the support foot mounting plate 306 can overlap the upper surface of the spring mounting seats 304. In this embodiment, the support mounting plate 306 is fixed to the upper surface of the column 303 by bolts. The entire support assembly 3 is mounted in the support mounting hole 104 of the base body 1 by overlapping the support mounting plate 306 with the spring mounting seat 304. There is an anti-slip pad mounting groove on the lower end surface of the support seat 309. An elastic anti-slip pad 310 is installed in the anti-slip pad mounting groove. The elastic anti-slip pad 310 can be installed in the anti-slip pad mounting groove by means of bonding or hot melting. The elastic anti-slip pad 310 includes, but is not limited to, a rubber pad, and its bottom surface protrudes from the lower end surface of the support seat 309.

[0038] The top plate 105 of the slot is provided with a mating hole 106 for the column 303 to pass through. A mating distance 307 corresponding to the mating stroke is left between the mating hole 106 and the column 303. The spring mounting seat 304 is fixed on the upper surface of the bottom plate 102.

[0039] During operation, the card dealing machine body 2 rotates relative to the base. When the card dealing machine starts or stops rotating, the force generated by the rotation acts on the base through the card dealing machine body 2, and the base acts on the support leg assembly 3, causing the base to move relative to the support leg assembly 3. During this process, the buffer spring 401 is compressed to buffer the rotation and reduce the impact force, keeping the card dealing machine stable during operation. Buffer springs 401 are provided on both sides of the column 303. Regardless of whether the card dealing machine rotates forward or backward, a buffer spring 401 will be compressed, achieving a good vibration reduction effect. Moreover, it can also allow the base and support leg assembly 3 to eventually return to their initial state, maintaining a balanced and stable position of the support leg 301 when stationary.

[0040] Meanwhile, in this embodiment, the buffer component 4 set between the base and the support leg 301 is used for buffering and shock absorption. It is completely separated from the internal transmission structure and card dealing structure of the card machine body 2, and does not interfere with the rotation and card dealing actions of the card machine. The vibration generated during the start-up and stop process is directly transmitted to the support leg 301 through the base without affecting the rotation transmission. The overall structure is more reasonable and more stable.

[0041] Example 2 Same as in Example 1, such as Figures 6-8As shown, the difference is that in this embodiment, in addition to the buffer spring 401, the buffer assembly 4 also includes two damping components 402 disposed between the base body 1 and the support leg 301. In this embodiment, the damping component 402 is a cylindrical component, which can be made of elastic materials such as rubber, silicone, and polyurethane.

[0042] The lower end face of the top plate 105 is provided with a damping element locking groove 107. The damping element 402 is locked into the damping element locking groove 107, and the lower part of the damping element 402 is pressed against the upper end face of the support leg 301. The upper and lower sides of the damping element 402 are pressed against the base body and the support leg respectively, which plays a corresponding motion damping role.

[0043] A guide groove 308 is provided on the upper surface of the mating part 302. The length direction of the damping component locking groove 107 and the guide groove 308 are consistent with the length direction of the mating groove 101. The upper and lower sides of the damping component 402 are respectively pressed between the damping component locking groove 107 and the lower guide groove 308, and the two ends of the damping component 402 in the length direction are respectively pressed against the two ends of the damping component locking groove 107. The upper and lower guide grooves can provide guidance for the movement of the damping component to ensure the stability of the base assembly and the support leg assembly during small-range relative movement.

[0044] During the start-up or shutdown process, the card machine body 2 transmits the rotational impact force to the base, causing the base to rotate and sway slightly. During this process, the damping component 402 is squeezed to absorb energy, further reducing vibration during the start-up and shutdown phases, thereby reducing noise and improving operational stability.

[0045] Meanwhile, the damping component 402 works in conjunction with the buffer spring 401 to buffer and absorb the rotational inertia, reduce the force on the base, and make the entire card machine more stable when stopped.

[0046] Example 3 Similar to Embodiment 2, except that in this embodiment, the upper surface of the mating part 302 is flat and no guide groove 308 is provided. The length direction of the damping component locking groove 107 intersects with the length direction of the mating groove 101. The length direction of the damping component 402 is consistent with the length direction of the damping component locking groove 107 and is locked in the damping component locking groove 107. This installation method makes the installation of the damping component simpler.

[0047] Example 4 Same as in Example 1 or Example 2, such as Figure 3 , Figure 9 as well as Figure 10 As shown, the difference is that the card machine in this embodiment is also provided with a rotation positioning component. The rotation positioning component includes a positioning component disposed between the part to be rotated and the support component. The base constitutes the support component, and the card machine body 2 constitutes the part to be rotated.

[0048] The positioning components include positioning component one 501 and positioning component two 502. Positioning component one 501 includes a light shield 503 disposed on the support and a photoelectric switch 504 disposed on the part to be rotated. The light shield is vertically upward and the light shield 503 can block the infrared emitting tube and infrared receiving tube of the slotted photoelectric switch during the rotation of the card machine body 2 on the base. Positioning component two 502 includes a magnet 505 disposed on the support and a Hall switch (not shown in the figure) disposed on the part to be rotated. The Hall switch and the slotted photoelectric switch are both commercially available conventional components and are electrically connected to the PCB board.

[0049] Among them, there are multiple light-shielding plates 503, which are evenly spaced around the rotation center of the rotating part on the support. The photoelectric switch 504 is a slotted photoelectric switch. The card machine body 2 is also equipped with a mounting plate. The mounting plate is equipped with a PCB board for controlling the photoelectric switch 504 and the Hall switch. The PCB board cooperates with the photoelectric switch 504 and the Hall switch. During the rotation of the card machine body 2, the slotted photoelectric switch will follow the movement, and then make it move relative to the light-shielding plate 503. When the light-shielding plate 503 moves between the infrared emitting tube and the infrared receiving tube of the slotted photoelectric switch in sequence, it blocks the light path and triggers the signal conversion. The PCB board controls the card dealing motor 204 and the rotation motor 203 to operate according to the signal of the photoelectric switch 504, thereby realizing effective control of the card dealing position.

[0050] The number of light-blocking sheets 503 is unlimited; in this embodiment, 12 are selected to accommodate various card dealing modes for two, three, or four players or multiples thereof. The card machine body 2 is equipped with a power switch and control keys, etc. Users can adjust the number of cards dealt, the number of players, and other card dealing modes through the control keys. Programs can be written to import different numbers of cards for different numbers of players in advance for convenient use by users.

[0051] To ensure more accurate card dealing, the rotating component has an initial mating position on the support. When the Hall switch and magnet 505 correspond, the initial mating position between the rotating component and the support is formed. When the machine is turned on, it will first determine whether the Hall switch and magnet 505 can sense each other. If not, the PCB board will control the rotary motor 203 to rotate the card machine body 2 to the position corresponding to the Hall switch and magnet 505. That is, this is the initial origin position between the card machine body 2 and the support. Based on the determination of this initial position, the subsequent slotted photoelectric switch and light shield 503 can better control the card dealing position.

[0052] Example 5 Same as in Embodiment 1, 2, or 3, such as Figure 2 , Figure 9As shown in the embodiment, the card machine body 2 includes a card compartment 201 and a transmission compartment 202 distributed vertically. The card compartment 201 forms a compartment body composed of a card base plate 206 and a card side plate 207. In this embodiment, the compartment body is open, which facilitates the stacking of cards in the compartment body. The card side plates 207 on both sides limit the cards. The two ends of the compartment body form a card outlet 213 and a card inlet 214, respectively. A card dispensing roller is provided on the card base plate 206 and located at the card inlet 214. The card dispensing roller pushes the card to the card outlet 213 for dispensing.

[0053] The transmission chamber 202 is equipped with a rotary motor 203 for driving the card machine body 2 to rotate, a card dispensing motor 204 for dispensing cards from the card compartment 201, and a battery 205 for supplying power to the card machine body 2. The battery 205 is located inside the transmission chamber 202 and directly above the rotary motor 203. The rotary motor 203, the card dispensing motor 204, and the battery 205 are all arranged at the rotation center of the card machine body 2.

[0054] Specifically, the rotary motor 203 includes a motor body 209 and a gearbox 210. A drive wheel is connected to the output shaft of the gearbox 210. The rotary motor 203 is fixed on the bottom surface of the transmission chamber 202. A rotary gear disk 212 connected to the drive wheel via a synchronous belt is provided at the center of the bottom surface of the transmission chamber 202. The common center of gravity of the rotary motor 203, the card-dealing motor 204, and the battery 205 is located on the central axis of the rotary gear disk 212.

[0055] The arrangement of the rotary motor 203, the card-distributing motor 204, and the battery 205 ensures that the overall center of gravity of the card machine body 2 is as close as possible to its rotation center, guaranteeing stability during rotation. On the other hand, it minimizes the size and height of the card machine. Compared to existing card machines with the battery 205 mounted on the top, this arrangement allows the card compartment 201 to be open, making it easier to put cards into the compartment. Compared to existing card machines with the battery 205 mounted on the rear side, the battery 205 is located at the center of the card machine body 2, enabling more stable rotation and ensuring a smoother card-distributing process.

[0056] In addition, the structural form of the card machine body 2 in this embodiment can also be adapted to the arrangement of the battery 205, the card dealing motor 204, and the rotary motor 203, as follows: In this embodiment, the card compartment 201 includes a card base plate 206 and a card side plate 207. The lower end face of the card base plate 206 forms a battery mounting surface, and a battery mounting seat 208 for mounting a battery 205 is fixed on the battery mounting surface. The bottom surface of the battery 205 is planar, and the upper end face of the rotary motor 203 is a supporting plane that supports the bottom of the battery 205. In this embodiment, the battery 205 can be, but is not limited to, a rechargeable lithium battery 205. Its shape is such that both the upper and lower end faces are planar, which facilitates its installation and better cooperation with the rotary motor 203. The outer shell of the rotary motor 203 is also constructed with both the upper and lower end faces being planar, so that the lower bottom surface of the battery 205 can be supported on the upper end face of the motor housing. The lower end face of the motor housing is directly mounted on the base plate 102 of the transmission compartment 202, reducing the height occupied by the battery 205 and the rotary motor 203 in the transmission compartment 202.

[0057] Additionally, the card base plate 206 is inclined downward from the card inlet 214 end to the card outlet 213 end. The rotary motor 203 and the card dispensing motor 204 are distributed on both sides of the central axis of the rotary gear disk 212, with the rotary motor 203 closer to the card inlet 214 side and the card dispensing motor 204 closer to the card outlet 213 side. The card base plate 102 forms the top plate of the transmission chamber 202. A support assembly is provided between the bottom plate 102 of the transmission chamber 202 and the card base plate 206. The support assembly includes a support seat 216 set at the card outlet 213 end and a support column 215 set at the card inlet 214 end. The height of the support column 215 is higher than the height of the support seat 216.

[0058] The card base plate 206 is tilted, and the rotary motor 203 and the card dealing motor 204 are arranged based on this tilted card base plate 206. On the one hand, this tilts the upper surface of the card base plate 206 from the card inlet 214 end to the card outlet 213 end, which is conducive to transporting cards to the card outlet 213. On the other hand, the height of the rotary motor 203 in the transmission compartment 202 is higher than the height of the card dealing motor 204, which provides space for the battery 205 to be installed above the rotary motor 203. This makes the overall structure of the card compartment 201 and the transmission compartment 202 compact, with a reasonable vertical distribution, small size, low center of gravity and height, and stable rotation and card dealing movement.

[0059] To further ensure the stability and smoothness of the card dealing, the base is equipped with multiple evenly distributed ball bearing mounting posts. The upper end of each ball bearing mounting post is fitted with a ball bearing that contacts the lower end of the card machine body. This allows the card machine body to rotate on the base, and the friction between the card machine body and the base can be rolling friction, ensuring the smoothness and stability of their relative rotation.

[0060] Example 6 Same as any one of embodiments 1-5, such as Figure 12As shown, this embodiment also provides another structural form of the card machine body, which is non-open type. The card machine bases in embodiments 1-5 can all be directly applied to the card machine body of this embodiment.

[0061] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, none of which exceed the protection scope of this application.

[0062] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
