Description

Technical Field

[0001] This utility model relates to the field of mahjong machine technology, and in particular to a detachable rotating disc and a mahjong machine. Background Technology

[0002] Mahjong machines, as specialized equipment to replace manual shuffling and improve the efficiency of mahjong entertainment, are widely used in homes, entertainment venues, and other settings. Their core functions revolve around automatic shuffling, tile arrangement, and tile placement. The mainstream products are fully automatic mahjong machines, while semi-automatic machines, which require manual tile pushing, have gradually been phased out of the market. In the core structure of a mahjong machine, the rotating disc is a key component for assisting in the arrangement and transport of mahjong tiles; its operational stability directly determines the overall user experience.

[0003] However, existing mahjong machine rotary tables still have significant technical defects in actual use and maintenance, mainly in the following two aspects: On the one hand, the existing rotating disc's disassembly and assembly structure is poorly designed, leading to difficult and inefficient maintenance. Taking the detachable rotating disc for mahjong machines disclosed in Chinese utility model patent CN219290584U as an example, although it claims to be easy to disassemble and assemble, it still relies on screws for fixation. This screw-fixing method has several problems: First, disassembly consumes a lot of time. The internal fixing screws are mostly hidden under the panel or components, requiring the outer shell to be removed before disassembly, and a specific screwdriver is needed, making the process cumbersome. Second, it requires skilled operators. Ordinary users lacking specialized tools or maintenance experience are prone to damaging the panel clips during disassembly, or stripping the screws due to improper force. Third, long-term use can lead to disassembly failure. If the mahjong machine is used in a humid environment, or if the screws are made of ordinary materials, they are prone to rust and stripping, making it impossible to disassemble the component properly. Re-fixing also makes it difficult to guarantee stability, often requiring forceful disassembly or replacement of the entire component, significantly increasing maintenance costs and wasting resources.

[0004] On the other hand, existing rotating discs lack effective dust cleaning mechanisms, which can easily lead to equipment malfunctions and affect user health with prolonged use. During daily use, mahjong tiles easily accumulate dust, dander, and other impurities on their surfaces. These impurities gradually fall into the machine's interior during the rotating disc's rotation and tile transport, especially accumulating in critical areas such as the disc's transmission gaps and bearings. As these impurities accumulate, they not only increase the rotating disc's operating resistance, causing rotational jamming and increased noise, but may even cause components to seize up, severely impacting the machine's normal operation. Furthermore, the accumulated dust breeds bacteria inside the machine, which can then spread into the surrounding environment with airflow and be inhaled by users, posing a potential threat to human health. Currently, there is no design for efficiently cleaning dust from inside the rotating disc, making dust a significant factor affecting the lifespan and safety of mahjong machines.

[0005] In summary, the current technical deficiencies of the rotating disc in mahjong machines regarding ease of disassembly and dust cleaning can no longer meet users' needs for equipment maintenance efficiency, operational stability, and health and safety. There is an urgent need to propose a rotating disc structure that can achieve quick disassembly and assembly and has efficient dust cleaning function to solve the above technical problems. Utility Model Content

[0006] To solve the above problems, this utility model provides a detachable rotating disc and a mahjong machine.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a detachable rotating disc and mahjong machine, including a housing, wherein a quick-release mechanism is provided inside the housing, the quick-release mechanism includes a sliding block for quick disassembly, and a dust extraction mechanism is also provided inside the housing, wherein the dust extraction mechanism includes multiple fans for dust extraction.

[0008] By adopting the above technical solution, the quick-release mechanism includes an installation plate fixedly installed inside the housing, a limiting cylinder fixedly installed on the outer side wall of the installation plate, a fixing plate fixedly installed inside the housing, an installation block fixedly installed at the bottom of the fixing plate, and an insertion post fixedly installed at the bottom of the installation block, the insertion post being inserted into the limiting cylinder.

[0009] Furthermore, by pulling the mounting plate, the limiting sleeve is placed on the outside of the insertion post, and the linkage limiting block and the locking block come into contact, thereby compressing the spring. This causes the locking block to move the sliding strip inside the sliding hole, and then the locking block reaches above the limiting block to achieve the locking function.

[0010] By adopting the above technical solution, a limiting block is fixedly installed at the bottom of the plug-in post, and the sliding block is slidably connected to the outside of the plug-in post.

[0011] Furthermore, the installed limiting blocks prevent detachment during snap-fit ​​fixing, effectively ensuring stability.

[0012] By adopting the above technical solution, two sliding holes are opened on both sides of the limiting cylinder. An installation ring is fixedly installed on the inner wall of the sliding hole. A spring is fixedly installed on one side of the installation ring. A snap-fit ​​block is fixedly connected to the other end of the spring. The snap-fit ​​block is in contact with the limiting block.

[0013] Furthermore, by manually pulling the mounting plate, the limiting cylinder slides on the outside of the insertion post, and the linkage locking block contacts the sliding block. Under the tension of the spring, the locking block reaches above the sliding block, thereby causing the sliding block to contact the limiting block, and thus causing the mounting plate to detach from the fixing plate.

[0014] By adopting the above technical solution, a sliding strip is slidably connected inside the two sliding holes. The sliding strip is located inside the spring and is connected to the snap-fit ​​block. A limit plate is fixedly installed at the other end of the sliding strip.

[0015] Furthermore, a limiting plate is installed to prevent the sliding bar from rebounding and falling off when the spring is compressed.

[0016] By adopting the above technical solution, a rotating disk is rotatably connected to the top of the mounting disk, a spindle is fixedly installed on the axis of the rotating disk, and a barrier strip is fixedly installed on the outer side of the spindle, and the barrier strip is connected to the rotating disk.

[0017] Furthermore, the installed barrier strips are used to sweep the mahjong tiles to a predetermined position for loading.

[0018] By adopting the above technical solution, the dust extraction mechanism includes air outlets opened on both sides of the housing, two sets of pull slots are opened on both sides of the housing, and pull frames are slidably connected inside the two sets of pull slots. A filter screen is detachably connected inside the pull frame, and a pull block is fixedly installed on one side of the pull frame.

[0019] Furthermore, by manually pulling the second pull block forward, the pull-out frame slides inside the pull-out slot, thereby pulling out the pull-out frame and replacing the filter screen inside the pull-out frame.

[0020] By adopting the above technical solution, an installation frame is fixedly installed on the inner wall of the pull-out groove, the fan is fixedly installed on one side of the installation frame, cover plates are hinged to both sides of the housing, and a pull block two is fixedly installed on one side of the cover plate, with the cover plate corresponding to the air outlet.

[0021] Furthermore, by activating multiple fans, the internal air is extracted, and during extraction, the internal dust is carried out. The dust is then blocked by the first pull block, thus concentrating the dust. Then, by manually pulling the second pull block forward, the cover is pulled, thereby cleaning the dust inside the air outlet.

[0022] A mahjong machine, wherein four support legs are fixedly installed at the bottom of the housing, the four support legs are respectively distributed at the four corners of the bottom of the housing, and anti-slip pads are fitted on the outer bottom of the four support legs.

[0023] Furthermore, four support legs are installed to support the housing and prevent the mahjong machine from tilting during use. Anti-slip pads are installed to prevent the mahjong machine from being affected by external factors and causing displacement.

[0024] In summary, this utility model has the following beneficial effects: 1. In this application, through the cooperation of the fixed plate, mounting plate, mounting block, plug-in post, sliding block, limit block, shaft post, barrier strip, rotating plate, limit cylinder, sliding hole, mounting ring, spring, snap-fit ​​block, limit plate, and sliding strip, during disassembly, the mounting plate is manually pulled, causing the limit cylinder to slide outside the plug-in post, and the snap-fit ​​block to contact the sliding block. Under the tension of the spring, the snap-fit ​​block reaches above the sliding block, thereby causing the sliding block to contact the limit block, and thus disengaging the mounting plate from the fixed plate. This avoids the need for disassembly using traditional screws during maintenance, saving disassembly time. During assembly, the mounting plate is pulled, causing the limit cylinder to be sleeved outside the plug-in post, and the limit block to contact the snap-fit ​​block, thereby compressing the spring. This causes the snap-fit ​​block to drive the sliding strip to slide inside the sliding hole, and thus the snap-fit ​​block reaches above the limit block, achieving the snap-fit ​​function, effectively saving assembly time.

[0025] 2. In this application, with the cooperation of the installed air outlet, pull-out slot, pull-out frame, pull block one, mounting bracket, fan, cover plate, pull block two, and filter screen, when the mahjong machine is used for a long time, the mahjong tiles may be contaminated with dust and enter the machine. By activating multiple fans, the internal air is drawn out, and the dust inside is carried out during the extraction. The dust is then blocked by pull block one, thus concentrating the dust. Then, by manually holding pull block two and pulling it forward, the cover plate is pulled, thereby concentrating and cleaning the dust inside the air outlet. This prevents the dust from being scattered into the air and inhaled by people during the dust extraction process, thus avoiding harm to the personnel. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-6 As shown in the figure, this application discloses a detachable rotating disk, including a housing 1, and a quick-release mechanism 2 is provided inside the housing 1. The quick-release mechanism 2 includes a sliding block 205 for quick disassembly. The quick-release mechanism 2 includes an installation plate 202 fixedly installed inside the housing 1. A limiting cylinder 210 is fixedly installed on the outer wall of the installation plate 202. A fixing plate 201 is also fixedly installed inside the housing 1. An installation block 203 is fixedly installed at the bottom of the fixing plate 201. An insertion post 204 is fixedly installed at the bottom of the installation block 203. The insertion post 204 is inserted into the limiting cylinder 210. During assembly, by pulling the installation plate 202, the limiting cylinder 210 is moved to fit outside the insertion post 204. The linkage limiting block 206 contacts the locking block 214, thereby compressing the spring 213. This causes the locking block 214 to move the sliding strip 216 inside the sliding hole 211, thereby allowing the locking block 214 to reach above the limiting block 206, realizing the locking function and effectively saving assembly time. In this embodiment, a limiting block 206 is fixedly installed at the bottom of the plug-in post 204, and a sliding block 205 is slidably connected to the outside of the plug-in post 204. The limiting block 206 is installed to prevent the plug from falling off during the snap-fit ​​fixing process, thus effectively ensuring stability. In this embodiment, the limiting cylinder 210 has two sliding holes 211 on both sides. An installation ring 212 is fixedly installed on the inner wall of the sliding hole 211. A spring 213 is fixedly installed on one side of the installation ring 212. A snap-fit ​​block 214 is fixedly connected to the other end of the spring 213. The snap-fit ​​block 214 is in contact with the limiting block 206. During disassembly, the installation plate 202 is manually pulled, which causes the limiting cylinder 210 to slide on the outside of the insertion post 204. The snap-fit ​​block 214 is then in contact with the sliding block 205. Under the tension of the spring 213, the snap-fit ​​block 214 reaches above the sliding block 205, thereby causing the sliding block 205 to contact the limiting block 206. This allows the installation plate 202 to detach from the fixing plate 201, avoiding the use of traditional screws for disassembly during maintenance and saving disassembly time. In this embodiment, a sliding strip 216 is slidably connected inside the two sliding holes 211. The sliding strip 216 is located inside the spring 213 and is connected to the snap-fit ​​block 214. A limiting plate 215 is fixedly installed at the other end of the sliding strip 216. The limiting plate 215 is used to limit the sliding strip 216 from rebounding and falling off when the spring 213 is compressed. In this embodiment, a rotating disk 209 is rotatably connected to the top of the mounting disk 202. A spindle column 207 is fixedly installed on the axis of the rotating disk 209. A barrier strip 208 is fixedly installed on the outer side of the spindle column 207. The barrier strip 208 is connected to the rotating disk 209. The installed barrier strip 208 is used to sweep the mahjong tiles to a predetermined position for loading.

[0030] The housing 1 is also equipped with a dust extraction mechanism 3, which includes multiple fans 306 for dust extraction. In this embodiment, the dust extraction mechanism 3 includes air outlets 301 on both sides of the housing 1. Two sets of pull slots 302 are provided on both sides of the housing 1. A pull frame 303 is slidably connected inside the two sets of pull slots 302. A filter screen 309 is detachably connected inside the pull frame 303. A pull block 304 is fixedly installed on one side of the pull frame 303. By manually holding the pull block 308 and pulling forward, the pull frame 303 slides inside the pull slot 302, thereby pulling out the pull frame 303 and replacing the filter screen 309 inside the pull frame 303, thus avoiding the filter screen 309 from becoming clogged due to long-term use. In this embodiment, a mounting bracket 305 is fixedly installed on the inner wall of the pull-out groove 302, and a fan 306 is fixedly installed on one side of the mounting bracket 305. A cover plate 307 is hinged to both sides of the housing 1, and a second pull block 308 is fixedly installed on one side of the cover plate 307. The cover plate 307 corresponds to the air outlet 301. When the mahjong machine is used for a long time, the mahjong tiles may be contaminated with dust and enter the machine. By starting multiple fans 306, the internal air is drawn out. During the drawing process, the internal dust is carried out and blocked by the first pull block 304, thereby concentrating the dust. Then, by manually holding the second pull block 308 and pulling it forward, the cover plate 307 is pulled, thereby concentrating and cleaning the dust inside the air outlet 301. This prevents the dust from being scattered in the air and inhaled by the human body during the dust extraction process, thus avoiding injury to the human body.

[0031] A mahjong machine has four support legs 4 fixedly installed at the bottom of the housing 1. The four support legs 4 are distributed at the four corners of the bottom of the housing 1. Anti-slip pads 5 are fitted on the outer bottom of the four support legs 4. The four support legs 4 are used to support the housing 1 and prevent the mahjong machine from tilting during use. The anti-slip pads 5 are used to prevent the mahjong machine from being affected by external factors and causing displacement.

[0032] The quick-release mechanism 2 is installed to avoid disassembly using traditional screws during maintenance, saving disassembly time. The dust extraction mechanism 3 is installed to prevent dust adhering to the mahjong tiles from entering the mahjong machine during long-term use and being unable to be discharged.

[0033] The operating principle of the detachable rotating disc and mahjong machine in this embodiment is as follows: The quick-release mechanism 2 avoids the need for traditional screws during maintenance, saving disassembly time. The dust extraction mechanism 3 prevents dust adhering to the mahjong tiles from entering the machine during prolonged use and becoming trapped inside. During assembly, pulling the mounting disc 202 causes the limiting cylinder 210 to fit over the outer side of the insertion post 204, linking the limiting block 206 to contact the locking block 214, thereby compressing the spring 213. This causes the locking block 214 to move the sliding strip 216 through the sliding hole. The internal sliding mechanism of plate 211 allows the locking block 214 to reach above the limiting block 206, achieving the locking function and effectively saving assembly time. During disassembly, manually pulling the mounting plate 202 causes the limiting cylinder 210 to slide outside the insertion post 204, linking the locking block 214 to contact the sliding block 205. Under the tension of the spring 213, the locking block 214 reaches above the sliding block 205, causing the sliding block 205 to contact the limiting block 206, thereby disengaging the mounting plate 202 from the fixing plate 201. This avoids the need for traditional screws during maintenance. The installation of the limit block 206 saves disassembly time. The limit block 206 prevents detachment during snap-fit ​​fixing, effectively ensuring stability. The limit plate 215 prevents the sliding strip 216 from rebounding and falling off when the spring 213 is compressed. The barrier strip 208 guides the mahjong tiles to the predetermined position for loading. Manually pulling the pull block 308 forward causes the pull-out frame 303 to slide inside the pull-out groove 302, thereby pulling out the pull-out frame 303 and allowing for the replacement of the filter screen 309 inside the pull-out frame 303. The filterless screen 309 may become clogged after prolonged use. During extended use of the mahjong machine, the mahjong tiles may accumulate dust, which may enter the machine. By activating multiple fans 306, the internal air is drawn out, carrying away the dust. The dust is then blocked by pull block 304, thus concentrating it. Then, by manually pulling pull block 308 forward, the cover 307 is pulled, thereby cleaning the dust inside the air outlet 301. This prevents dust from being scattered into the air during the dust extraction process and being inhaled by people, thus avoiding harm to their health.

All technical solutions falling within the scope of this utility model's concept are protected.
