Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to a dice plate of a mahjong machine. Background Art

[0002] After the dice tray of the mahjong machine has been used for a period of time, the glass inside the dice tray will be contaminated with dust, which will affect the user's observation of the dice points from the outside, so the glass in the dice tray needs to be removed and cleaned frequently. The glass in the dice tray is clamped on the cover of the dice tray by a clamp ring, and the glass can be removed after the clamp ring is removed.

[0003] Existing clamping rings are generally injection molded parts, and are equipped with integrally injection molded buckles, which are connected to the cover of the dice plate through the buckles. Although the buckles themselves have a certain strength, they rely on the overall deformation of the buckles to complete the connection during installation, and the same is true for disassembly. For rigid plastic structures, there are undoubtedly potential problems such as deformation and even cracking of the clamping ring and buckle. Utility Model Content

[0007] Preferably, the flexible positioning portion comprises a hollow portion for increasing the amount of flexible deformation, and / or a flat portion is provided on a side surface of the flexible positioning portion.

[0008] Preferably, the positioning column and the clamping ring are separately provided, and the positioning column includes a fixing portion, and the fixing portion is installed at the lower end of the clamping ring.

[0009] Preferably, the clamping ring includes limiting walls arranged on both sides of the fixing portion, and the limiting walls form a cavity for accommodating at least a portion of the fixing portion.

[0010] Preferably, both ends of the fixing portion extend out of the cavity, and the fixing portion located outside the cavity extends toward the limiting wall to form limiting ribs, and the limiting ribs stop outside the limiting wall to limit the fixing portion.

[0011] Preferably, a limiting protrusion is further provided on the inner side of the clamping ring, and the limiting protrusion is provided between the dice observation window and the fixing portion.

[0012] Preferably, a slot is provided on a side of the cover shell away from the positioning column, and a tongue is correspondingly provided on the clamping ring, and the tongue cooperates with the slot to position the clamping ring at an end away from the positioning column.

[0013] Preferably, a plurality of the positioning posts are circumferentially arranged on the inner side of the clamping ring.

[0014] Preferably, the dice observation window is a glass piece.

[0015] Preferably, the clamp ring is made of a hard metal material and is integrally formed by die-casting, the positioning column is made of a flexible material, and the clamp ring and the positioning column are separately arranged.

[0016] The utility model also provides a mahjong machine, which adopts the dice plate described in any one of the above technical solutions.

[0017] After adopting the above technical solution, the utility model has the following beneficial effects.

[0018] 1. According to the mahjong machine dice plate proposed by the utility model, the clamp ring is fixed to the cover shell by snapping the flexible positioning part on the positioning column. It should be noted here that the flexible positioning part mentioned in the present disclosure has higher elastic deformation ability and tensile resistance than the hard plastic buckle, and is usually made of soft rubber material, such as rubber / silicone / soft PVC, etc. Therefore, compared with the previous method of rigid connection between the clamp ring and the cover shell using a buckle structure, during the disassembly and assembly of the clamp ring, the flexible positioning part passes through the positioning hole by its own deformation, and the flexible positioning part itself has better elastic deformation ability, which makes the disassembly and assembly of the clamp ring more convenient, and the structure of the positioning column itself is not easily damaged;

[0019] According to the mahjong machine dice plate proposed by the utility model, the clamping ring needs to press the dice observation window to avoid loosening, and the assembly tolerance of the buckle, the cover shell and the dice observation window must be taken into consideration. Due to the rigidity of the buckle, a buckle that is too long or too short cannot achieve the expected assembly effect. In practice, the control of such tolerance often requires higher costs. The flexible positioning part disclosed in the present invention can compensate for the assembly tolerance of the clamping ring, the cover shell and the dice observation window through its own deformation, because it can be compressed and deformed, which means that sufficient interference can be reserved between the flexible positioning part and the cover shell. It is not only used to buckle the flexible positioning part to the cover shell, but also can provide a pre-tightening force in the direction in which the clamping ring presses the dice observation window, thereby reducing the difficulty of component manufacturing while ensuring the assembly effect.

[0020] 2. The flexible positioning part includes a large diameter end, a small diameter end and a transition part connected therebetween, and the transition part gradually shrinks from the large diameter end to the small diameter end. By arranging the large diameter end, the small diameter end and the transition part on the flexible positioning part, there is a gap between the small diameter end and the positioning hole, and the flexible positioning part can be placed on the positioning hole to achieve the pre-positioning of the positioning column and the positioning hole; at the same time, the gradual retraction of the transition part can guide the flexible positioning part to gradually press into the positioning hole at the correct position during the user's downward pressure, which can further optimize the user's operation and improve the user's experience.

[0021] 3. The flexible positioning portion includes a hollow portion for increasing the amount of flexible deformation, and / or a flat portion is provided on the side of the flexible positioning portion. In this way, the hollow portion and / or the flat portion provide additional deformation space for the flexible positioning portion in the radial direction, thereby increasing the amount of flexible deformation of the flexible positioning portion. The user needs less force to insert the positioning column into the positioning hole, further improving the user experience.

[0022] 4. The positioning column and the clamp ring are separately set. The positioning column includes a fixing part, which is installed at the lower end of the clamp ring. When a buckle structure is adopted, since the buckle and the clamp ring cannot be separately set, the entire clamp ring needs to be replaced when the buckle is damaged. The separate design of the positioning column and the clamp ring means that there is no need to replace the entire clamp ring when the positioning column is damaged, and the maintenance cost of the mahjong machine is lower.

[0023] 5. The clamping ring includes limiting walls arranged on both sides of the fixing part, the limiting walls enclose a cavity for accommodating at least part of the fixing part, and the limiting walls provide limiting for the positioning column in the front and rear or left and right directions, so that the positioning column can be better limited to the inner side of the clamping ring, reducing the probability of the positioning column detaching from the clamping ring during use.

[0024] 6. Both ends of the fixing part extend out of the cavity, and the fixing part located outside the cavity extends toward the limiting wall to form limiting ribs, and the limiting ribs stop at the outside of the limiting wall to limit the fixing part. In this way, the limiting ribs cooperate with the limiting wall to better limit the fixing part on the clamping ring, thereby reducing or avoiding the probability of the positioning column detaching from the clamping ring during use.

[0025] 7. A limiting protrusion is also provided on the inner side of the clamping ring. The limiting protrusion is provided between the dice observation window and the fixed part. The inner side of the positioning column is close to the dice observation window. If too much force is applied to the clamping ring, the root of the positioning column is likely to deform or move inward due to the lever effect, that is, the fixed part tends to be out of the cavity. Therefore, a limiting protrusion is provided on the inner side of the clamping ring to better limit the positioning column. Even if a large force is applied to the clamping ring, the limiting protrusion can effectively limit the positioning column to prevent the positioning column from being out of the clamping ring.

[0026] 8. A slot is provided on one side of the cover away from the positioning column, and a tongue is correspondingly provided on the clamping ring. The tongue cooperates with the slot to position the clamping ring at the end away from the positioning column. By providing the tongue at the end of the clamping ring away from the positioning column and providing the slot accordingly on the cover, the tongue can be inserted into the slot first when installing the clamping ring, and then the clamping ring can be installed on the cover. The tongue and the slot provide pre-positioning for the installation of the clamping ring to avoid the clamping ring from being unable to be installed in the wrong position. At the same time, the tongue and the slot cooperate with the positioning column after the clamping ring is installed in place, and provide limit positions on at least two ends of the clamping ring, so that the clamping ring installed in place is more firmly limited and the clamping ring is not easily separated from the installation position.

[0027] 9. There are multiple positioning posts, and the multiple positioning posts are circumferentially arranged on the inner side of the clamp ring. In this way, the clamp ring is installed and positioned through the multiple positioning posts, so that the multiple ends of the clamp ring in the circumference form limit positions, so that the installed clamp ring is more firmly limited and the clamp ring is not easily separated from the installation position; and when the positioning posts are arranged to be circumferentially symmetrical, the clamp ring can be installed from multiple placement directions, and the installation of the clamp ring is simpler.

[0028] 10. The dice observation window is made of glass, which has good transparency. In addition, since the dice observation window will collide with the dice when in use, and the dice are usually made of hard plastic, and the hardness of glass is harder than the dice, it is less likely to scratch the dice observation window if glass is used.

[0029] 11. The clamp ring is made of hard metal and is integrally formed by die-casting. Usually, the clamp ring is made of plastic. During use, the clamp ring is in sliding contact with the mahjong tiles for a long time, which easily leaves scratches on the clamp ring, affecting the aesthetics of the dice box. However, the clamp ring made of hard metal is difficult to leave scratches during the sliding contact with the mahjong tiles, so it can better maintain the aesthetics of the dice box; and, since the positioning column and the clamp ring are separate structures, if the positioning column is damaged, only this single part needs to be replaced, thereby reducing the cost of replacing the damaged limiting structure between the clamp ring and the cover.

[0030] The utility model also provides a mahjong machine. Since the mahjong machine dice plate of any one of the above technical solutions is adopted, the mahjong machine has all the technical effects of the above mahjong machine dice box.

[0031] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0050] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] Embodiment 1:

[0052] like Figures 1 to 8As shown, a dice tray for a mahjong machine proposed in an embodiment of the utility model includes a cover 300, a dice box 500, a dice observation window 400 and a collar 100. A cavity with an open upper end is formed on the cover 300, the dice box 500 is arranged in the cavity, the dice observation window 400 is detachably arranged on the dice box 500, and the collar 100 is installed on the cover 300 to limit the dice observation window 400. A positioning column 200 is provided at the lower end of the collar 100, and the positioning column 200 includes a flexible positioning portion 220. A positioning hole 301 is provided on the cover 300, and the flexible positioning portion 220 passes through the positioning hole 301 through flexible deformation and is buckled on the cover 300, so that the collar 100 limits the dice observation window 400 on the cover 300.

[0053] The so-called flexible deformation refers to the property that the flexible positioning part 220 can produce elastic deformation under the action of external force, and when the external force is removed, the flexible positioning part 220 can return to its original state. When the collar 100 is installed on the cover 300, radial extrusion is generated between the flexible positioning part 220 and the positioning hole 301 by pressing down the collar 100, and the flexible positioning part 220 produces flexible deformation so that the flexible positioning part 220 can gradually pass through the positioning hole 301. The direction of the flexible deformation of the flexible positioning part 220 can be radial, for example: inward or outward; it can also be axial, for example, along the direction away from the insertion direction or the insertion direction; it can also be radial and axial at the same time.

[0054] When the user needs to remove the collar 100, the user can use a sheet tool to insert into the gap between the collar 100 and the housing 300 and pry upward to remove the collar 100, thereby removing the dice observation window 400 for wiping and cleaning. After the dice observation window 400 is wiped clean, it is put back in place, and the collar 100 is installed on the housing 300 through the positioning column 200, so that the dice observation window 400 is limited on the housing 300.

[0055] Exemplarily, the flexible positioning portion 220 may also be made of a soft plastic material, such as soft PVC, etc.; the flexible positioning portion 220 may also be made of rubber or silicone.

[0056] In this embodiment, the collar 100 is fixed to the housing 300 by snapping the flexible positioning part 220 on the positioning column 200. It should be noted that the flexible positioning part 220 mentioned in the present disclosure has higher elastic deformation ability and tensile strength than the hard plastic buckle, and is usually made of soft rubber material, such as rubber / silicone / soft PVC, etc. Therefore, compared with the previous method of rigid connection between the collar 100 and the housing 300 using the buckle structure, during the disassembly and assembly of the collar 100, the flexible positioning part 220 passes through the positioning hole 301 by its own deformation, and the flexible positioning part 220 itself has better elastic deformation ability, which makes the disassembly and assembly of the collar 100 more convenient, and the structure of the positioning column 200 itself is not easily damaged;

[0057] According to the mahjong machine dice plate proposed by the utility model, the clamping ring 100 needs to press the dice observation window 400 to avoid loosening, and the assembly tolerance of the buckle, the cover shell 300 and the dice observation window 400 must be taken into consideration. Due to the rigidity of the buckle, a buckle that is too long or too short cannot achieve the expected assembly effect. In practice, the control of such tolerance often requires higher costs. The flexible positioning part 220 disclosed in the present invention can compensate for the assembly tolerance of the clamping ring 100, the cover shell 300 and the dice observation window 400 through its own deformation, because it can be compressed and deformed, which means that sufficient interference can be reserved between the flexible positioning part 220 and the cover shell 300. It is not only used to buckle the flexible positioning part 220 to the cover shell 300, but also can provide a pre-tightening force in the direction in which the clamping ring 100 presses the dice observation window 400, thereby reducing the difficulty of component manufacturing while ensuring the assembly effect.

[0058] The end of the positioning column 200 away from the flexible positioning portion 220 can be fixedly connected to the collar, for example, by threaded connection, glue bonding, clamping, keyway connection, etc. The positioning column 200 can be integrally formed at the lower end of the collar.

[0059] This embodiment is preferred, such as Figure 3 , Figures 6 to 8 As shown, the flexible positioning portion 220 includes a large diameter end 221, a small diameter end 222 and a transition portion 223 connected therebetween, and the transition portion 223 gradually shrinks from the large diameter end 221 to the small diameter end 222. In this embodiment, the large diameter end 221 has an interference fit with the positioning hole 301, and the small diameter end 222 has a clearance fit with the positioning hole 301.

[0060] By arranging a large diameter end 221, a small diameter end 222 and a transition portion 223 on the flexible positioning portion 220, a gap is provided between the small diameter end 222 and the positioning hole 301, and when the flexible positioning portion 220 is placed on the positioning hole 301, the positioning column 200 and the positioning hole 301 can be pre-positioned; at the same time, the gradual retraction of the transition portion 223 can guide the flexible positioning portion 220 to gradually press into the positioning hole 301 at the correct position during the user's downward pressing process, thereby further optimizing the user's operation and improving the user's experience.

[0061] In another preferred embodiment, Figure 3 As shown, a flat portion 224 is provided on the side of the flexible positioning portion 220 . When the flexible positioning portion 220 passes through the positioning hole 301 , a gap is maintained between at least part of the flat portion 224 and the positioning hole 301 .

[0062] With such arrangement, when the flexible positioning portion 220 passes through the positioning hole 301, the flat portion 224 provides additional deformation space in the radial direction for the flexible positioning portion 220, thereby making it easier for the flexible positioning portion 220 to pass through the positioning hole 301, and less force is required for the user to insert the positioning column 200 into the positioning hole 301, thereby further improving the user experience.

[0063] In another preferred embodiment, Figure 3 As shown, the flexible positioning portion 220 is provided with a hollow portion 225 for increasing the amount of flexible deformation.

[0064] With such a configuration, the hollow portion 225 provides additional deformation space in the radial direction for the flexible positioning portion 220. When the flexible positioning portion 220 passes through the positioning hole 301, the flexible positioning portion 220 can flexibly deform inward, thereby making it easier for the flexible positioning portion 220 to pass through the positioning hole 301. The user also needs less force to insert the positioning column 200 into the positioning hole 301, thereby further improving the user experience.

[0065] In this embodiment, the dice observation window is a transparent piece. Preferably, the dice observation window is a glass piece. The glass piece has good transparency, and because the dice observation window will collide with the dice when in use, and the dice is usually made of hard plastic, and the hardness of glass is harder than the dice, it is less likely to scratch the dice observation window by using a glass piece.

[0066] Embodiment 2:

[0067] Based on the first embodiment, in this embodiment, if Figures 2 to 4 As shown, the positioning column and the clamp ring are separately arranged, and the positioning column includes a fixing portion, which is installed at the lower end of the clamp ring.

[0068] When the buckle structure is adopted, since the buckle and the clamp ring 100 cannot be separated, the clamp ring 100 needs to be replaced as a whole when the buckle is damaged. However, the positioning column 200 is designed to be separated from the clamp ring 100, so there is no need to replace the entire clamp ring 100 when the positioning column 200 is damaged, and the maintenance cost of the mahjong machine is lower.

[0069] It can be understood that the positioning column 200 can be integrally formed of the same material, that is, the fixing part 210 and the flexible positioning part 220 are both made of flexible material, so as to have the same hardness; it can also be a fixed combination of parts with different hardness; it can also be made of the same material, and different parts have different hardness through different processing techniques.

[0070] In a preferred embodiment of the present invention, the clamping ring 100 includes limiting walls 120 disposed on both sides of the fixing portion 210 , and the two limiting walls 120 enclose a cavity 121 for accommodating at least a portion of the fixing portion 210 .

[0071] The limiting wall 120 provides limiting for the positioning column 200 in the front-back or left-right direction, so that the positioning column 200 can be better limited to the inner side of the clamping ring 100, reducing the probability of the positioning column 200 being separated from the clamping ring 100 during use.

[0072] This embodiment is more preferably, as Figures 2 to 4 As shown, both ends of the fixing portion 210 extend out of the cavity 121 , and the fixing portion 210 located outside the cavity 121 extends toward the limiting wall 120 to form limiting ribs 211 , which stop outside the limiting wall 120 to limit the fixing portion 210 .

[0073] In this configuration, the limiting rib 211 cooperates with the limiting wall 120 to better limit the fixing portion 210 on the clamping ring 100 , thereby reducing or avoiding the probability of the positioning column 200 being separated from the clamping ring 100 during use.

[0074] This embodiment is further preferred, as Figures 2 to 4 As shown, the fixing portion 210 is flexible and deforms when inserted into the cavity 121 . A deformation groove 211 is provided at the junction of the fixing portion 210 and the limiting rib 211 . The deformation groove 211 can increase the deformation of the fixing portion 210 and the limiting rib 211 .

[0075] With such a configuration, it is easier to install the fixing portion 210 into the cavity 121 , which simplifies the operation difficulty for the operator and provides convenience for the installation or subsequent maintenance of the clamping ring 100 .

[0076] In another more preferred embodiment, Figure 5 As shown, a limiting protrusion 130 is also provided on the inner side of the clamping ring 100 , and the limiting protrusion 130 is arranged between the dice observation window 400 and the positioning column 200 .

[0077] The inner side of the positioning column 200 is close to the dice observation window 400. If too much force is applied to the clamping ring 100, the root of the positioning column 200 is likely to deform or move inward due to the lever effect, that is, the fixing portion 210 tends to be separated from the cavity 121. Therefore, a limiting protrusion 130 is provided on the inner side of the clamping ring 100 to better limit the positioning column 200. Even if a large force is applied to the clamping ring 100, the limiting protrusion 130 can effectively limit the positioning column 200 to prevent the positioning column 200 from being separated from the clamping ring 100.

[0078] For details not described in this embodiment, please refer to the first embodiment.

[0079] Embodiment three:

[0080] Based on the first and second embodiments, Figure 2 , Figures 4 to 6As shown, in this embodiment, a slot 302 is provided on the side of the cover 300 away from the positioning post 200, and a tongue 110 is correspondingly provided on the collar 100. The tongue 110 cooperates with the slot 302 to position the collar 100 at the end away from the positioning post 200.

[0081] By providing an inserting tongue 110 at one end of the collar 100 away from the positioning post 200 and correspondingly providing a slot 302 on the cover 300, when installing the collar 100, the inserting tongue 110 can be first inserted into the slot 302, and then the collar 100 can be installed on the cover 300. The inserting tongue 110 and the slot 302 provide pre-positioning for the installation of the collar 100, thereby preventing the collar 100 from being unable to be installed in the wrong position; at the same time, the inserting tongue 110 and the slot 302 cooperate with the positioning post 200 after the collar 100 is installed in place, providing a limit position on at least two ends of the collar 100, so that the installed collar 100 is more firmly limited, and the collar 100 is not easy to be separated from the installation position.

[0082] For the contents not described in this embodiment, reference may be made to the above embodiments.

[0083] Embodiment 4:

[0084] Based on Embodiments 1 to 2, in this embodiment, reference Fig. 9 There are multiple positioning posts 200, and the multiple positioning posts 200 are circumferentially arranged on the inner side of the collar 100. In this way, the collar 100 is installed and positioned by the multiple positioning posts 200, so that the multiple ends of the collar 100 in the circumferential direction form a limit, so that the collar 100 installed in place is more firmly limited, and the collar 100 is not easy to be separated from the installation position; and when the positioning posts 200 are arranged to be circumferentially symmetrical, the collar 100 can be installed from multiple placement directions, and the installation of the collar 100 is simpler.

[0085] For the contents not described in this embodiment, reference may be made to the above embodiments.

[0086] Embodiment five:

[0087] Based on embodiments 1 to 4, in this embodiment, reference Figure 1 The clamp ring 100 is made of hard metal and is integrally formed by die-casting, the positioning column 200 is made of flexible material, and the clamp ring 100 and the positioning column 200 are separately arranged.

[0088] Usually, the collar 100 is made of plastic material. During use, the collar 100 is in sliding contact with mahjong tiles for a long time, which easily leaves scratches on the collar 100, thereby affecting the aesthetics of the dice box 500. However, the collar 100 made of hard metal is less likely to leave scratches during the sliding contact with mahjong tiles, thereby better maintaining the aesthetics of the dice box 500; and, since the positioning column 200 and the collar 100 are separately arranged, if the positioning column 200 is damaged, only this single part needs to be replaced, thereby reducing the cost of replacing the damaged limiting structure between the collar 100 and the cover 300.

[0089] For the contents not described in this embodiment, reference may be made to the above embodiments.

[0090] Embodiment six:
