Description

Technical Field

[0001] This utility model relates to the field of mahjong machine technology, and in particular to a mahjong machine tile-dropping silencing device. Background Technology

[0002] Ordinary mahjong machines produce a harsh sound when the mahjong tiles fall onto the shuffling tank and impact the tile-pulling strip and lifting tube, which affects the enjoyment of playing. Therefore, a soundproof cover is usually installed at the lifting plate of the mahjong machine to reduce the noise when the mahjong tiles fall.

[0003] Because existing mufflers are one-piece molded structures, the lifting plate installed on the lifting rod must be disassembled before the muffler can be installed or disassembled. The whole process is quite cumbersome and will reduce the speed of installation or disassembly of the muffler. Utility Model Content

[0004] To solve the above problems, this utility model provides a mahjong machine tile-dropping silencing device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mahjong machine tile-dropping silencing device, comprising a base, the base being installed on a rotating turntable inside the mahjong machine, a lifting rod being provided on the base, a lifting plate being provided on the top of the lifting rod, two mutually abutting positioning blocks being provided on the side wall of the base, the side wall of the base being abutting against the side wall of the two positioning blocks being close to each other, a silencing cover being fixed on each of the two positioning blocks, and a connecting mechanism for fixing the two positioning blocks being provided together on the two positioning blocks.

[0006] By adopting the above technical solution, the connecting mechanism is first used to release the fixed state between the two positioning blocks, and then the two positioning blocks are separated from each other, which can realize the disassembly of the two mufflers. Similarly, the two blocks are brought close to each other and then the connecting mechanism is used to fix the two positioning blocks, which can realize the installation of the two mufflers. This eliminates the need for the cumbersome operation of disassembling or installing the lifting plate before installing or disassembling the muffler, which is required by existing technology, thus improving the speed of muffler disassembly or installation.

[0007] Furthermore, one of the positioning blocks has a slot, and a limiting through hole communicating with the slot is provided through the positioning block. The connecting mechanism includes a connecting component, which includes an insert block fixed to another positioning block and inserted into the slot, an elastic plate fixed to the insert block and having an L-shaped structure, and a limiting block fixed to the horizontal section of the elastic plate near the limiting through hole. The limiting block passes through the limiting through hole and is inserted into it. The connecting mechanism also includes a disassembly component for separating the limiting block from the limiting through hole.

[0008] By adopting the above technical solution, the limiting block and the limiting through hole are separated by disassembling the components. At this point, the two positioning blocks can be separated until the insert block is separated from the slot, thus completing the disassembly of the two positioning blocks. Similarly, the insert block is inserted into the slot. During this process, the limiting block contacts the top wall of the slot. The limiting block is subjected to force, which causes the end of the elastic plate near the limiting through hole to deform downwards until the limiting block moves to the position of the limiting through hole. Since the slot and the limiting block are not in contact at this time, the elastic plate gradually deforms upwards and causes the limiting block to move until the limiting block is inserted into the limiting through hole, thus achieving the purpose of fixing the two positioning blocks. The operation is simple and convenient, and easy for operators to use.

[0009] Furthermore, the disassembly assembly includes a mounting shell fixed to the positioning block at a position corresponding to the limiting through hole, a push rod that passes through the mounting shell and slides with the mounting shell, a connecting plate fixed to the push rod and located inside the mounting shell, and a first spring fixed between the connecting plate and the positioning block.

[0010] By adopting the above technical solution, when the push rod is pressed down, the first spring is stressed and gradually contracts. During this process, the push rod contacts the top of the limiting block until the limiting block is pushed out of the limiting through hole. At this time, the insert block can be removed from the slot. The setting of the disassembly component facilitates the disassembly of the two positioning blocks.

[0011] Furthermore, the insert block is provided with an installation groove, and the connection mechanism also includes an auxiliary component. The auxiliary component includes a push block that slides in the installation groove and a thrust spring that is fixed between the push block and the inner sidewall of the installation groove and is in a retracted state. The push block abuts against the inner sidewall of the limiting through hole.

[0012] By adopting the above technical solution, when the limiting block and the limiting through hole are separated, the thrust spring gradually extends and generates a thrust force on the push block and the insert block. The insert block is driven by the force to slide the positioning block fixed to it away from the other positioning block a certain distance. At this time, the two positioning blocks can be separated, which facilitates the disassembly of the two positioning blocks.

[0013] Furthermore, a buffer mechanism is jointly provided on the lifting rod and the positioning block. The buffer mechanism includes buffer components, the number of which is equal to the number of positioning blocks and their positions correspond one-to-one. Each buffer component includes two connecting blocks that are slidably disposed on the side wall of the lifting rod and closely attached to each other, elastic blades fixed on the connecting blocks, connecting rods fixed on the connecting blocks, and sleeves fixed on the positioning blocks and inserted into the connecting rods. Each connecting block has eight elastic blades and two connecting rods. The number of connecting rods is equal to the number of sleeves and their positions correspond one-to-one. The buffer mechanism also includes a support component for resetting the connecting rods.

[0014] By adopting the above technical solution, the lifting rod descends and drives the lifting plate to move. During this process, the lifting rod contacts the connecting block, the connecting block is subjected to force and drives the connecting rod to descend until the lifting plate is flush with the mahjong machine table. Similarly, the lifting rod rises and drives the lifting plate to move. During this process, the support component drives the connecting rod to rise and reset. The connecting rod drives the connecting block to rise, which in turn causes the elastic blade connected to the connecting block to rise and move to the working position. At this time, the user pushes the mahjong tiles from the holes opened on the mahjong machine table onto the turntable inside the mahjong machine. During this process, the mahjong tiles first fall onto the elastic blades, which cushion the mahjong tiles. Then, the mahjong tiles fall onto the surface of the soundproof cover to further reduce the noise generated when the mahjong tiles fall. Finally, the mahjong tiles slide off the surface of the soundproof cover onto the turntable of the mahjong machine, thereby reducing the sound generated when the mahjong tiles fall.

[0015] Furthermore, the sleeve is provided with a sliding through hole communicating with the inside of the sleeve, and the support assembly includes a slider fixed to the connecting rod and slidingly engaged with the sliding through hole, and a support spring fixed between the slider and the positioning block.

[0016] By adopting the above technical solution, during the descent of the lifting rod, the connecting rod drives the slider to move, the support spring is stressed and gradually contracts. Similarly, during the descent of the lifting rod, the support spring is stressed and gradually extends and returns to its original position, thereby driving the connecting rod connected to the support spring and the slider connected to the connecting rod to rise and return to their original position, thus ensuring the normal noise reduction purpose of the device.

[0017] Furthermore, a resistance block is fixed on the positioning block and is in close contact with the side wall of the base. A wavy groove is formed on the inner wall of the resistance block that is in contact with the base.

[0018] By adopting the above technical solution, the setting of the resistance block and the wave-shaped groove improves the friction when the positioning block is connected to the base surface.

[0019] Furthermore, the support assembly also includes a vertical rod fixed in the sliding through hole, the vertical rod passing through the slider and slidingly engaging with it.

[0020] By adopting the above technical solution, the vertical rod is well limited, which improves the stability of the slider during lifting and lowering.

[0021] In summary, the present invention has the following beneficial effects: In this application, by setting two positioning blocks, two soundproof covers and a connecting mechanism, the cumbersome operation of disassembling or installing the lifting plate is eliminated when installing or disassembling the soundproof cover, which is required by the prior art, thus improving the speed of disassembling or installing the soundproof cover.

[0024] 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.

[0025] like Figure 1-6As shown in the figure, this application discloses a mahjong machine tile-dropping silencing device, including a base 1, a connecting mechanism 6, and a buffer mechanism 10. The base 1 is installed on a rotating turntable inside the mahjong machine. A lifting rod 2 is provided on the base 1, and a lifting plate 3 is provided on the top of the lifting rod 2. Two positioning blocks 4 are provided on the side wall of the base 1, which are close to each other. The side wall of the base 1 is close to the side wall of the two positioning blocks 4, and a silencing cover 5 is fixed on each of the two positioning blocks 4. A slot 7 is opened on one of the positioning blocks 4, and a limiting through hole 8 communicating with the slot 7 is provided through the positioning block 4. First, operate the connecting mechanism 6 to release the fixed state between the two positioning blocks 4. Then, separate the two positioning blocks 4 from each other to disassemble the two mufflers 5. Similarly, bring the two blocks close to each other and abut them. Then, operate the connecting mechanism 6 to fix the two positioning blocks 4 to install the two mufflers 5. This eliminates the need for the cumbersome operation of disassembling or installing the lifting plate 3 before installing or disassembling the mufflers 5, thus improving the speed of disassembling or installing the mufflers 5.

[0026] A connecting mechanism 6 is mounted on two positioning blocks 4 and is used to fix the two positioning blocks 4. The connecting mechanism 6 includes a connecting component 61, a disassembly component 62, and an auxiliary component 63. The connecting component 61 includes an insert block 611, an elastic plate 612, and a limiting block 613. The insert block 611 is fixed to the other positioning block 4 and is inserted into the slot 7. The insert block 611 has an installation groove 9. The elastic plate 612 is fixed to the insert block 611 and has an L-shaped structure. The limiting block 613 is fixed to the horizontal section of the elastic plate 612 near the limiting through hole 8. The limiting block 613 has a right-angled trapezoidal structure and is inserted into the limiting through hole 8. The limiting block 613 is separated from the limiting through hole 8 by the disassembly component 62. At this time, the two positioning blocks 4 can be separated until the insert block 611 is separated from the slot 7, thus completing the disassembly of the two positioning blocks 4. Similarly, when inserting the insert 611 into the slot 7, the limiting block 613 contacts the top wall of the slot 7. The limiting block 613 is subjected to force and causes the end of the elastic plate 612 near the limiting through hole 8 to deform downwards until the limiting block 613 moves to the position of the limiting through hole 8. Since the slot 7 and the limiting block 613 are in a non-contact state at this time, the elastic plate 612 gradually deforms upwards and causes the limiting block 613 to move until the limiting block 613 is inserted into the limiting through hole 8, thereby completing the purpose of fixing the two positioning blocks 4. The operation is simple and convenient, and easy for operators to use.

[0027] The disassembly assembly 62 is used to separate the limiting block 613 from the limiting through hole 8. The disassembly assembly 62 includes a mounting shell 621, a push rod 622, a connecting plate 623, and a first spring 624. The mounting shell 621 is fixed on the positioning block 4 at the position corresponding to the limiting through hole 8. The push rod 622 passes through the mounting shell 621 and slides in cooperation with it. The connecting plate 623 is fixed on the push rod 622 and located inside the mounting shell 621. The first spring 624 is fixed between the connecting plate 623 and the positioning block 4. When the push rod 622 is pressed downward, the first spring 624 is stressed and gradually contracts. During this process, the push rod 622 contacts the top of the limiting block 613 until the limiting block 613 is pushed out of the limiting through hole 8. At this point, the insert block 611 can be removed from the slot 7. The disassembly assembly 62 facilitates the disassembly of the two positioning blocks 4.

[0028] The auxiliary component 63 includes a push block 631 and a thrust spring 632. The push block 631 is slidably fitted within the mounting groove 9. The push block 631 abuts against the inner wall of the limiting through hole 8, and the thrust spring 632 is fixed between the push block 631 and the inner wall of the mounting groove 9 and is in a retracted state. When the limiting block 613 separates from the limiting through hole 8, the thrust spring 632 gradually extends and generates a thrust acting on the push block 631 and the insert block 611. The insert block 611, under the force, is driven to slide a distance away from the other positioning block 4, thus separating the two positioning blocks 4 and facilitating their disassembly.

[0029] A buffer mechanism 10 is jointly mounted on the lifting rod 2 and the positioning block 4. The buffer mechanism 10 includes a buffer assembly 101 and a support assembly 102. The number of buffer assemblies 101 is equal to the number of positioning blocks 4, and their positions correspond one-to-one. The buffer assembly 101 includes a connecting block 1011, elastic blades 1012, connecting rods 1013, and a sleeve 1014. The connecting blocks 1011 are slidably mounted on the side wall of the lifting rod 2 and are tightly fitted together. Two connecting blocks 1011 are provided and are symmetrically arranged about the axis of the lifting rod 2. The elastic blades 1012 are fixed to the connecting blocks 1011, and each connecting block 1011 has eight elastic blades 1012. The connecting rods 1013 are fixed to the connecting blocks 1011, and each connecting block 1011 has two connecting rods 1013. The sleeve 1014 is fixed on the positioning block 4 and is inserted into the connecting rod 1013. The number of connecting rods 1013 is equal to the number of sleeves 1014 and their positions correspond one-to-one. The lifting rod 2 descends and drives the lifting plate 3 to move. During this process, the lifting rod 2 contacts the connecting block 1011, the connecting block 1011 is subjected to force and drives the connecting rod 1013 to descend until the lifting plate 3 is flush with the mahjong machine table. Similarly, the lifting rod 2 rises and drives the lifting plate 3 to move. During this process, the support component 102 drives the connecting rod 1013 to rise and reset. The connecting rod 1013 drives the connecting block 1011 to rise, which in turn causes the elastic blade 1012 connected to the connecting block 1011 to rise and move to the working position. At this time, the user pushes the mahjong tiles from the holes opened on the mahjong machine table onto the turntable inside the mahjong machine. During this process, the mahjong tiles first fall onto the elastic blade 1012, which cushions the mahjong tiles. Then the mahjong tiles fall onto the surface of the soundproof cover 5 to further reduce the noise generated when the mahjong tiles fall. Finally, the mahjong tiles slide off the surface of the soundproof cover 5 onto the turntable of the mahjong machine, thereby reducing the sound generated when the mahjong tiles fall.

[0030] A sliding through hole 11 communicating with the inside of the sleeve 1014 is provided through the sleeve 1014. The support assembly 102 includes a slider 1021 fixed to the connecting rod 1013 and slidably engaged with the sliding through hole 11, and a support spring 1022 fixed between the slider 1021 and the positioning block 4. During the descent of the lifting rod 2, the connecting rod 1013 drives the slider 1021 to move, and the support spring 1022 is stressed and gradually contracts. Similarly, during the ascent of the lifting rod 2, the support spring 1022 is stressed and gradually extends and returns to its original position, thereby driving the connecting rod 1013 connected to the support spring 1022 and the slider 1021 connected to the connecting rod 1013 to rise and return to their original position, thus ensuring the normal noise reduction purpose of the device.

[0031] A resistance block 12 is fixed on the positioning block 4 and is in close contact with the side wall of the base 1. A wavy groove is formed on the inner wall of the resistance block 12 that is in contact with the base 1. The resistance block 12 and the wavy groove improve the friction when the positioning block 4 is connected to the surface of the base 1.

[0032] The support assembly 102 also includes a vertical rod 1023, which is fixed inside the sliding through hole 11 and passes through the slider 1021 and slides in engagement with it. The vertical rod 1023 provides good limiting, which improves the stability of the slider 1021 when it rises and falls.
