AI Technical Summary
Existing card sorting machines are prone to instability when folded.
The design incorporates rotating legs and a rotating shaft. By adapting the rotating shaft to the shaft hole, the rotation of the rotating legs becomes more stable. The rotation shaft abuts against the wall of the shaft hole to share the weight of the card sorting machine. The combination of fixed legs and rotating legs increases the support range and reduces the possibility of tipping over.
This design allows the card sorting machine to be placed more stably after folding, reducing the risk of tipping over, and without increasing vertical space usage.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of card sorting machine technology, specifically to a foldable card sorting machine base and a card sorting machine. Background Technology
[0002] To facilitate transportation and save storage space when not in use, existing card sorting machines can be hinged to the top of a column. During transportation or storage, the card sorting machine body is flipped and folded along the hinge, so that the bottom of the card sorting machine body fits against the column, thereby achieving the purpose of convenient transportation and storage and saving space.
[0003] However, in order to further save space, existing card sorting machines will also fold or extend the base under the column that supports the card sorting machine. However, the existing folding or extension method moves the movable base inward to the fixed base, which makes it easy for the card sorting machine to be placed unstable after folding. Utility Model Content
[0004] To address the technical problem that existing card sorting machines tend to be unstable when folded, this utility model provides a foldable card sorting machine base and a card sorting machine.
[0005] To achieve the objectives of this utility model, the following technical solution is adopted:
[0006] A foldable card sorting machine base includes a base body and at least a pair of rotating legs. One of the base body and the rotating legs is provided with a rotating shaft, and the other is provided with a matching shaft hole. The rotating legs are rotatably mounted on the base body through the shaft hole and the rotating shaft.
[0007] During the movement of the rotating support leg toward the folding side of the card sorting machine, the two rotating support legs of the same pair rotate in a direction away from each other, and during the movement of the rotating support leg away from the folding side of the card sorting machine, the two rotating support legs of the same pair rotate in a direction closer to each other.
[0008] Furthermore, one end of the rotating support leg is provided with a bushing having the shaft hole.
[0009] Furthermore, the rotating shaft extends laterally above the bushing to form a spacer plate, and a foot cover is provided below the bushing on the rotating shaft.
[0010] Furthermore, the lateral width of the spacer is greater than the wall thickness of the bushing.
[0011] Furthermore, one or more spacers are provided between the rotating support leg and the base body.
[0012] Furthermore, the spacer plate is disposed on the rotating support leg and / or the base body, and the rotating shaft extends laterally below the shaft hole to form a limiting platform or is provided with a foot cover.
[0013] Furthermore, the base also includes at least one fixed support foot mounted on the base body, and the rotating support foot and the fixed support foot are respectively arranged on the lateral sides of the base body.
[0014] Furthermore, the base body is provided with a first pad on the side facing the fixed support foot, and the base body is provided with a second pad on the side facing the rotating support foot. The thickness of the first pad is greater than the thickness of the second pad, and the spacer protrudes from the surface of the second pad or the surface of the rotating support foot.
[0015] Furthermore, the sum of the thickness of the spacer protruding from the surface of the second pad or the surface of the rotating support and the thickness of the second pad is equal to the thickness of the first pad.
[0016] Furthermore, the free end of the rotating leg and / or the free end of the fixed leg are provided with a support member.
[0017] Furthermore, the support member is a caster wheel or a pad.
[0018] Furthermore, the base body is provided with a rotating component, and the first end of the rotating support leg is rotatably connected to the rotating component.
[0019] Furthermore, the rotating component includes a first gear mounted on the mounting end of the rotating leg, which meshes with the first gears on the two pairs of rotating legs.
[0020] Furthermore, the rotating component includes a first gear mounted on the mounting end of the rotating support leg and a second gear mounted on the base body, wherein the first gear meshes with the second gear.
[0021] Furthermore, the two second gears of the same pair are connected by a connecting shaft, which is rotatably mounted on the base body;
[0022] Alternatively, the two second gears in the same pair mesh with each other;
[0023] Alternatively, the two second gears in the same pair mesh with each other through a gear set.
[0024] Furthermore, the rotating component is a connecting rod assembly whose two ends are respectively connected to the mounting ends of the two rotating legs of the same pair.
[0025] Furthermore, the base body is provided with a driving component, which is drivenly connected to the rotating support leg or the rotating component.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: By adapting the rotating shaft to the shaft hole, the rotation of the rotating legs is made more stable. Furthermore, the contact between the rotating shaft and the hole wall distributes the pressure exerted on the base by the weight of the card sorting machine, preventing the rotating legs from deforming and pressing against the base body, thus preventing them from rotating relative to the base body. When the card sorting machine needs to be folded, controlling the rotating legs to move towards the folding side of the card sorting machine reduces the space occupied by the base in the lateral direction. Moreover, since the two rotating legs in the same pair rotate in a direction away from each other, i.e., the two rotating legs in the same pair spread outwards, the support range for the base body and the card sorting machine body on the base body is increased, which can disperse the force acting on it, reduce the possibility of tipping over, and make the card sorting machine more stable when folded and stored.
[0027] In addition, this utility model also provides a card sorting machine, the specific solution of which is as follows:
[0028] A card sorting machine includes a foldable card sorting machine base.
[0029] Furthermore, the card sorting machine can be a mahjong machine, a poker machine, a dominoes machine, or a dominoes machine.
[0030] The card sorting machine provided by this utility model includes the aforementioned base and therefore has the same function as the base. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0044] In this document, terms such as "upper," "lower," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.
[0045] In this definition, flipping refers to a rotation from the horizontal direction to the vertical direction, and rotation refers to a rotation on approximately the same horizontal plane, ignoring vertical movement caused by gravity or gaps.
[0046] Figure 1 In the diagram, the X direction is horizontal, the Y direction is vertical, and the Z direction is vertical.
[0047] See Figure 1-5 The base 1 of the card sorting machine of this utility model can be set below the card sorting machine body to support the card sorting machine body. Figure 1The diagram only shows the bottom of the card sorting machine. Further, the card sorting machine can be a mahjong machine, a poker machine, a domino machine, or a domino machine. If it is a mahjong machine, the card sorting machine includes a shell, a shuffling device for shuffling the cards, a card feeding device for picking up mahjong cards one by one from the shuffling tray of the shuffling device and feeding them out, a card stacking device for stacking two mahjong cards into a pile, a card pushing device for pushing mahjong cards into the storage slot, and a card lifting device for feeding the stacked mahjong cards onto the table. The specific structure of the card sorting machine is widely disclosed and will not be described in detail here.
[0048] See Figure 1-5 This embodiment provides a base 1 for a foldable card sorting machine, including a base body 11 and at least a pair of rotating legs 12 rotatably mounted on the base body 11. One of the base body 11 and the rotating legs 12 is provided with a rotating shaft 111, and the other is provided with a matching shaft hole 12a. The rotating legs 12 are rotatably mounted on the base body 11 through the shaft hole 12a and the rotating shaft 111. When the rotating legs 12 move toward the folding side of the card sorting machine, the two rotating legs 12 of the same pair rotate toward each other in a direction away from each other. When the rotating legs 12 move away from the folding side of the card sorting machine, the two rotating legs 12 of the same pair rotate toward each other in a direction close to each other.
[0049] In detail, by adapting the rotating shaft 111 to the shaft hole 12a, the rotation of the rotating support 12 is made more stable. Furthermore, by abutting the wall of the rotating shaft 111 to the shaft hole 12a, the pressure brought by the weight of the card sorting machine to the base 1 is shared, preventing the rotating support 12 from deforming and pressing against the base body 11, thus preventing it from rotating relative to the base body 11.
[0050] When the card sorting machine needs to be folded, the rotating legs 12 are moved closer to the folding side of the card sorting machine, which reduces the space occupied by the base 1 in the horizontal direction. Since the two rotating legs 12 rotate in opposite directions, i.e., they open outwards, the support range for the base body 11 and the card sorting machine body on the base body 11 is increased, distributing the force acting on them and reducing the possibility of tipping over, making the card sorting machine more stable when folded and stored. When the card sorting machine needs to be unfolded, the two rotating legs 12 are rotated closer to each other to a predetermined position, where they, together with the fixed legs 13 on the base body 11, provide stable support for the card sorting machine body. Similarly, the card sorting machine is also stably supported by the fixed legs 13 and the rotating legs 12 when folded. Preferably, after the two rotating legs 12 are opened outwards to the predetermined position, the combined longitudinal length occupied by the two rotating legs 12 is less than or equal to the longitudinal length of the card sorting machine body, to avoid increasing the vertical space occupied. Here, "folding side" refers to the side where the card sorting machine body is located after the card sorting machine has been flipped and folded. "Closer" and "farther" refer to the free ends of the two rotating legs 12 of the same pair being closer or further apart.
[0051] See Figure 1 , 6 7, 9. The base body 11 is equipped with at least one fixed support leg 13, and the rotating support leg 12 and the fixed support leg 13 are respectively arranged on the lateral sides of the base body 11. In one example, when there is one fixed support leg 13, the fixed support leg 13 is located on the folding side, and preferably the fixed support leg 13 is generally T-shaped, V-shaped, or W-shaped. In another example, at least a pair of fixed support legs 13 are installed, and at least a pair of fixed support legs 13 are located on the folding side of the card sorting machine, so that the card sorting machine remains stable. See [reference needed]. Figure 1 This example uses two fixed legs 13 and two rotating legs 12; in other examples, there may be four fixed legs 13 and two rotating legs 12, with the two fixed legs 13 forming a pair, and the two pairs being spaced apart horizontally.
[0052] Preferably, vertically, the outermost rotating support leg 12 and the fixed support leg 13 are approximately located at the corners of the card sorting machine to provide stable support. More preferably, when the rotating support leg 12 is in the supported state, the angle formed by the center lines of the two outermost rotating support legs 12 is approximately 90°, and the angle formed by the center lines of the two outermost fixed support legs 13 is approximately 90°, making the card sorting machine more stable.
[0053] Further, see Figure 1 , 67, 9. The free ends of the rotating support leg 12 and / or the free ends of the fixed support leg 13 are provided with support members 14, which can serve to support the base body 11. Preferably, the support member 14 is a caster wheel, which facilitates the movement of the card sorting machine. When the user is not using the card sorting machine, it can be moved to a suitable location for storage, which is convenient for the user. It should be noted that the support member 14 can also be a pad, which can also serve a supporting function. Preferably, it is a rubber pad.
[0054] Further, see Figure 4-5 One end of the rotating support 12 is provided with a bushing 121 having a shaft hole 12a. The bushing 121 can be manufactured separately with precision, and the fit between the bushing 121 and the rotating shaft 111 can be controlled more precisely, reducing the difficulty of setting a precise shaft hole 12a for the rotating support 12. Alternatively, the bushing 121 with a shaft hole 12a can also be provided on the base body 11.
[0055] Further, see Figure 5 A partition plate 122 is provided between the rotating support leg 12 and the base body 11. The partition plate 122 separates the rotating support leg 12 from the base body 11, so that there is a gap between the rotating support leg 12 and the base body 11, thereby reducing the friction between the rotating support leg 12 and the base body 11 and facilitating the rotational movement.
[0056] In one example, see Figure 5 A rotating shaft 111 extends laterally above the bushing 121 to form a spacer 122. A foot cover 112 is provided below the bushing 121 on the rotating shaft 111. The rotating foot 12 is installed on the rotating shaft 111 and then the foot cover 112 is installed. Preferably, the lateral width of the spacer 122 is greater than the wall thickness of the bushing 121, so that the rotating foot 12 can at least partially abut against the spacer 122 to withstand pressure.
[0057] In another example, a spacer 122 is provided on the rotating support 12 and / or the base body 11, and the rotating shaft 111 extends laterally below the shaft hole 12a to form a limiting platform or is provided with a foot cover 112. Preferably, there is more than one spacer 122, which is selected according to actual needs.
[0058] Further, see Figure 1-3The base body 11 has a first pad 113 on the side facing the fixed support leg 13, and a second pad 114 on the side facing the rotating support leg 12. The thickness of the first pad 113 is greater than the thickness of the second pad 114. A spacer 122 protrudes from the surface of the second pad 114 or the surface of the rotating support leg 12, facilitating adjustment of the distance between the surface of the rotating support leg 12 and the surface of the base body 11. Preferably, the sum of the thickness of the spacer 122 protruding from the surface of the second pad 114 or the surface of the rotating support leg 12 and the thickness of the second pad 114 is equal to the thickness of the first pad 113, so that the base body 11 is horizontal and stably supports the card sorting machine.
[0059] Further, see Figure 7-10 The base body 11 is provided with a rotating component 4. The mounting end of the rotating leg 12 is rotatably connected to the rotating component 4. It can be understood that the rotating leg 12 and the rotating component 4 can move and cooperate with each other while also restricting each other, making the rotation of the rotating leg 12 more stable and preventing it from rotating and moving arbitrarily. The mounting end refers to the end of the rotating leg 12 that is connected to the base body 11.
[0060] Each of the two rotating legs 12 in a pair can be connected to a rotating component 4 to rotate independently. That is, there is no linkage structure between the two rotating legs 12 in a pair. For example, the rotating component 4 includes a first gear 41 installed on the mounting end of the rotating leg 12 and a second gear 42 installed on the base body 11. The first gear 41 and the second gear 42 mesh with each other, but the two second gears 42 are set independently and do not mesh. The first gear 41 rotates relative to the second gear 42.
[0061] Preferably, the two rotating legs 12 of the same pair rotate synchronously. In one example, the rotating member 4 includes a first gear 41 mounted on the mounting end of the rotating leg 12, and the first gears 41 on the two rotating legs 12 of the same pair mesh with each other.
[0062] In another example, the rotating component 4 includes a first gear 41 mounted on the mounting end of the rotating support leg 12 and a second gear 42 mounted on the base body 11, with the first gear 41 meshing with the second gear 42. In one example, the two second gears 42 in a pair are connected by a connecting shaft 43, which is rotatably mounted on the base body 11. The connecting shaft 43 and the two second gears 42 in a pair rotate synchronously. Figure 1-2As shown in Figures 7-8, the first gear 41 is a bevel gear, and the second gear 42 is a conical gear. If the connecting shaft 43 rotates, the conical gear on it rotates accordingly, and the bevel gear meshing with the conical gear moves, thereby driving the two rotating legs 12 of the same pair to rotate synchronously. If one of the rotating legs 12 rotates, the bevel gear on it drives the meshing conical gear to rotate, which also drives the connecting shaft 43 and the other conical gear to rotate. The rotation of the other conical gear drives the other rotating leg 12 to rotate, thus achieving synchronous rotation of the two rotating legs 12 of the same pair. In another example, the two second gears 42 of the same pair mesh with each other, and the second gear 42 can be equivalent to a bridge gear set between the two first gears 41 of the same pair. In another example, the two second gears 42 of the same pair mesh with each other through a gear set, that is, the two first gears 41 of the same pair are connected by multiple bridge gears. The bridge gear changes the rotation direction of the rotating legs 12 to ensure that the two rotating legs 12 of the same pair move away from each other when the folding machine is folding. Figure 9-10 As shown, taking the arrangement of two intermediate gears as an example, each of the two rotating legs 12 in the same pair meshes with one intermediate gear, and the two intermediate gears mesh together. The first gear 41 is preferably a sector gear, and more preferably, the sector gear and the rotating leg 12 are an integral structure. The two first gears 41 in the same pair refer to two first gears 41 respectively provided on the two rotating legs 12 in the same pair; the two second gears 42 in the same pair refer to two second gears 42 respectively meshing with the two first gears 41 in the same pair.
[0063] In another example, the rotating component 4 is a linkage assembly (not shown) with its two ends respectively connected to the mounting ends of the two rotating legs 12 of the same pair. The linkage assembly may include a movable seat mounted on the base body 11, two rotatable connecting movable seats and linkages respectively connected to the rotating legs 12, or a linkage in the form of a four-bar linkage mechanism. There are many existing disclosures of linkage assemblies, so they will not be described in detail here. As long as they can drive the two rotating legs 12 of the same pair to rotate synchronously.
[0064] Furthermore, the rotating leg 12 can be manually controlled to move. When the user needs to store it, they can directly kick the rotating leg 12 to make it rotate and move towards the folding side. Alternatively, a drive handle can be installed on the rotating leg 12, and the user can drive the rotating leg 12 to rotate and move towards the folding side by using the drive handle when the user needs to store it.
[0065] See Figure 6-8Preferably, the movement of the rotating support leg 12 is controlled by the driving component 5. Specifically, the driving component 5 is provided on the base body 11. In one example, the driving component 5 can be driven to rotate the rotating support leg 12 directly. In another example, the driving component 5 is driven to rotate the rotating component 4, such as by driving the first gear 41, the second gear 42, the connecting shaft 43, the gear set, or the moving seat. The driving component 5 can be connected to the rotating component 4 by driving gear or driving belt, or it can be directly connected to the rotating component 4.
[0066] The driving component 5 can be a drive motor or a drive cylinder, and different driving components 5 can be used according to different needs and conditions. It can be understood that if the two rotating legs 12 of the same pair rotate individually, then each of the two rotating legs 12 of the same pair is connected to a driving component 5, or the driving component 5 is connected through the rotating part 4 of the rotating leg 12; if they rotate synchronously, then only one of the two rotating legs 12 of the same pair is connected to a driving component 5, or the rotating part 4 connecting the two rotating legs 12 of the same pair is connected to the driving component 5.
[0067] Furthermore, a transmission component (not shown) is provided between the rotating component 4 and the driving component 5, so that the position of the driving component 5 can be adjusted according to the actual situation, which facilitates the installation of the driving component 5. In addition, the rotation direction of the rotating component 4 can also be adjusted by the transmission component as needed.
[0068] Without contradicting the spirit and technical means of this utility model, at least some of the technical implementation methods in the above embodiments can be combined or replaced.
[0069] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is defined by the scope of the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of this utility model should also be considered as protection within the scope of this utility model.
