Description

Technical Field

[0001] This utility model relates to the field of music box technology, and more specifically to a music box with movable decorative parts. Background Technology

[0002] A music box is a musical instrument used for playing music. The music played by a music box has the characteristics of pure and crisp tone, which is determined by its mechanical sound production principle. Therefore, whether it is classical music excerpts or traditional folk songs, they can be presented to users in a simple and unpretentious way.

[0003] Traditional music boxes often focus on expanding the musical performance function, such as adding harmonic effects to the main melody, or increasing the diversity of repertoire and performance styles, but neglect the development of other extended functions, resulting in a monotonous user experience. To address this, decorative parts are set on the music box and connected to the internal transmission mechanism, so that they can move along with the music during performance, thereby adding dynamic beauty, enriching visual layers, and creating a better thematic atmosphere. Here, we take Chinese patent CN214847696U, entitled "A Music Box Transmission Device with Moving Decorative Parts", as an example. It includes a spring, a sound-producing steel plate, a roller, a mechanism shaft, and a transmission plate set inside the box body. The key feature is that a mounting plate is coaxially set on the mechanism shaft, and a rotating mounting groove is opened on one radial side of the mounting plate. One end of the transmission plate is rotatably connected to the rotating mounting groove, and a magnet is embedded on the upper surface of the other end of the transmission plate. The end of the transmission plate connected to the rotating mounting groove is bent upward and has a limiting part, the outer wall of which abuts against the upper edge of the opening of the rotating mounting groove.

[0004] The decorative parts on the music box can rotate with the transmission plate. However, the problem is that the transmission plate can only drive the decorative parts to maintain circular motion and cannot present rhythmic changes according to the music performance. Visually, it can only provide a relatively simple layer, which can easily cause visual fatigue for users and make it difficult to accurately express the emotions and atmosphere of the music theme. Utility Model Content

[0005] In response to the above issues, and to overcome the problems that the decorative parts on existing music boxes can only maintain simple circular motion and cannot present rhythmic changes according to the music playing, thus providing only a relatively simple visual layer, easily causing visual fatigue for users, and making it difficult to accurately express the emotions and atmosphere of the musical theme, the purpose of this utility model is to provide a music box that can control the decorative parts to jump up and down with the music playing, presenting obvious rhythmic changes, thereby better enhancing the emotions and atmosphere of the musical theme, and allowing users to enjoy the visual experience while listening to music.

[0006] To achieve the above objectives, the technical solution of this utility model is:

[0007] A music box with movable decorative parts includes a box body. Inside the box body are a drive shaft, an eccentric wheel, a push rod, a drive gear, a driven gear, and a handle. The eccentric wheel and the driven gear are both mounted on the drive shaft. The push rod is positioned above the eccentric wheel and abuts against it. The push rod passes through the top of the box body. The drive gear is mounted on the handle and meshes with the driven gear. One end of the handle extends through the box body into the external space.

[0008] Preferably, a spring is fitted onto the top rod, with the two ends of the spring abutting against the inner top wall of the box and the bottom of the top rod, respectively.

[0009] Preferably, a limiting seat is formed on the inner top wall of the box corresponding to the top rod, the top rod passes through the limiting seat, a limiting block is formed at the bottom of the top rod, the limiting seat and the limiting block are vertically opposite each other, and the two ends of the spring abut against the limiting seat and the limiting block respectively.

[0010] Preferably, the drive shaft includes a front shaft and a rear shaft, a driven gear is sleeved on the mating position of the front shaft and the rear shaft, and an eccentric wheel is sleeved on the front shaft and the rear shaft.

[0011] Preferably, the front axle has 3 eccentric wheels and the rear axle has 1 eccentric wheel.

[0012] Preferably, an upper rod support is formed on the inner top wall of the box corresponding to the drive shaft, and a lower rod support is formed on its inner bottom wall. A first slot is provided on the top of the lower rod support, and the first slot is engaged with the drive shaft.

[0013] The inner bottom wall of the box also has a first gear seat and a second gear seat corresponding to the drive shaft. The first gear seat and the second gear seat are located on both sides of the driven gear. The first gear seat has a second slot and the second gear seat has a third slot. Both the second slot and the third slot are engaged with the drive shaft.

[0014] Preferably, the box body is also provided with a mechanism base, and a first handle support and a second handle support are formed on the mechanism base corresponding to the handle. A fourth slot is provided on the first handle support and a fifth slot is provided on the second handle support. Both the fourth slot and the fifth slot are engaged with the handle.

[0015] The movement base also has a third gear seat corresponding to the handle, and the third gear seat and the first handle support are located on both sides of the drive gear.

[0016] Preferably, the box body includes an upper box body and a lower box body. An upper guide tube is formed at the bottom of the upper box body, and a lower guide tube is formed at the top of the lower box body. The upper guide tube is inserted into the lower guide tube and fixed by screws.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] When this music box plays music, the user turns the handle to drive the drive gear to rotate, which in turn drives the meshing driven gear to rotate. The driven gear transmits power to the transmission shaft, and the eccentric wheel is driven by the transmission shaft to drive the push rod to move up and down, causing the decorative parts to jump up and down. Based on the differences in the style and setting angle of different eccentric wheels, the decorative parts are allowed to jump alternately and can jump at different amplitudes, so that the decorative parts present obvious rhythmic changes with the music, thereby better highlighting the emotion and atmosphere of the music theme, allowing the user to enjoy the visual experience while listening to the music.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, this utility model relates to a music box with movable decorative parts. It includes a box body 1, inside which are arranged a drive shaft 2, an eccentric wheel 3, a push rod 4, a driving gear 5, a driven gear 6, and a handle 7. Multiple eccentric wheels 3 are arranged, with the eccentric wheels 3 and driven gears 6 sequentially mounted on the drive shaft 2, forming an eccentric connection. The push rod 4 is positioned above the eccentric wheels 3 and abuts against them, extending through the top of the box body 1 and forming a sliding fit with it. The portion of the push rod 4 outside the box body 1 is used to connect decorative parts. When the drive shaft 2 rotates, the eccentric wheels 3 rotate eccentrically, thus lifting the corresponding push rod 4 when rotating upwards, or allowing the push rod 4 to move downwards under gravity when rotating downwards. Thus, the decorative parts connected to the push rod 4... The decorative pieces can move up and down. The driving gear 5 is mounted on the handle 7 and meshes with the driven gear 6. One end of the handle 7 extends through the box body 1 into the external space for the user to hold. When the music box plays music, the user turns the handle 7 to drive the driving gear 5 to rotate. The driving gear 5 drives the meshing driven gear 6 to rotate. The driven gear 6 transmits power to the transmission shaft 2. The eccentric wheel 3 is driven by the transmission shaft 2 to drive the push rod 4 to move up and down, causing the decorative pieces to move up and down. Based on the differences in the style and setting angle of different eccentric wheels 3, the decorative pieces are allowed to move alternately and can move at different amplitudes, so that the decorative pieces present obvious rhythmic changes with the music, thereby better highlighting the emotion and atmosphere of the music theme and allowing the user to enjoy the visual experience while listening to the music.

[0030] like Figures 1 to 4 As shown, a spring 8 is fitted on the top rod 4. The spring 8 can maintain directional extension and contraction through the support of the top rod 4. The two ends of the spring 8 abut against the inner top wall of the box 1 and the bottom of the top rod 4, respectively. The spring 8 will be compressed when the eccentric wheel 3 rotates upward to drive the top rod 4 to move upward. When the eccentric wheel 3 rotates downward, the spring 8 is allowed to return to its original deformation. The elastic force of the return deformation, combined with gravity, enables the top rod 4 and the connected decorative parts to move downward in time, ensuring that the decorative parts can move up and down flexibly.

[0031] like Figure 2As shown, a limiting seat 101 is formed on the inner top wall of the box 1 corresponding to the top rod 4. The top rod 4 passes through the limiting seat 101, and a limiting block 401 is formed at the bottom of the top rod 4. The limiting seat 101 and the limiting block 401 are vertically opposite each other. The two ends of the spring 8 abut against the limiting seat 101 and the limiting block 401 respectively. This ensures that the spring 8 can smoothly extend and retract when the top rod 4 moves up and down, and effectively avoids deviation with the support of the top rod 4.

[0032] like Figure 4 and Figure 5 As shown, the drive shaft 2 consists of a front shaft 201 and a rear shaft 202. The driven gear 6 is fitted onto the mating position of the front shaft 201 and the rear shaft 202, so that the driven gear 6 can transmit power to both the front shaft 201 and the rear shaft 202 simultaneously, causing the front shaft 201 and the rear shaft 202 to rotate. The eccentric wheel 3 is fitted onto the front shaft 201 and the rear shaft 202. When the front shaft 201 and the rear shaft 202 rotate, the eccentric wheel 3 connected to each will drive the corresponding push rod 4 to move. The above arrangement can increase the number of eccentric wheels 3 that can be set, and correspondingly increase the number of decorative parts. When a large number of decorative parts move up and down at the same time, it will provide a variety of visual layers, thereby avoiding visual fatigue for users and better and more accurately expressing the emotion and atmosphere of the music theme.

[0033] Furthermore, the front axle 201 has 3 eccentric wheels 3, and the rear axle 202 has 1 eccentric wheel 3.

[0034] like Figure 1 , Figure 2 , Figures 4 to 6As shown, an upper rod support 102 is formed on the inner top wall of the box 1 corresponding to the drive shaft 2, and a lower rod support 103 is formed on its inner bottom wall. It should be noted that there are multiple sets of upper rod supports 102 and corresponding lower rod supports 103, which are arranged at intervals along the length of the drive shaft 2. A first slot 103a is provided at the top of the lower rod support 103, which engages with the drive shaft 2. The first slot 103a supports the drive shaft 2, and the top opening of the first slot 103a is closed by the upper rod support 102. In this way, the upper rod support 102 and the lower rod support 103 can limit the movement of the drive shaft 2, ensuring... The drive shaft 2 can always rotate in a specific position. In addition, a first gear seat 104 and a second gear seat 105 are formed on the inner bottom wall of the housing 1 corresponding to the drive shaft 2. The first gear seat 104 and the second gear seat 105 are located on both sides of the driven gear 6, so that the driven gear 6 can be limited by the first gear seat 104 and the second gear seat 105 and stably maintain a connection with the drive shaft 2. A second slot 104a is provided on the first gear seat 104, and a third slot 105a is provided on the second gear seat 105. The second slot 104a and the third slot 105a are both engaged on the drive shaft 2, thereby working together with the lower rod support 103 to support the drive shaft 2.

[0035] like Figure 1 , Figure 2 , Figures 4 to 6 As shown, the housing 1 also includes a mechanism base 9. A first handle support 901 and a second handle support 902 are formed on the mechanism base 9 corresponding to the handle 7. The first handle support 901 and the second handle support 902 have similar functions to the lower rod support 103. A fourth slot 901a is provided on the first handle support 901, and a fifth slot 902a is provided on the second handle support 902. Both the fourth slot 901a and the fifth slot 902a are engaged with the handle 7, thus supporting the handle 7 and allowing it to remain rotating in a specific position. Furthermore, a third gear seat 903 is formed on the mechanism base 9 corresponding to the handle 7. The third gear seat 903 and the first handle support 901 are located on both sides of the drive gear 5, allowing the drive gear 5 to be limited by the third gear seat 903 and the first handle support 901, ensuring a stable connection with the handle 7.

[0036] like Figure 1 , Figure 3 and Figure 4As shown, the box 1 includes an upper box 1a and a lower box 1b. An upper conduit 106 is formed at the bottom of the upper box 1a, and a lower conduit 107 is formed at the top of the lower box 1b. The upper conduit 106 is inserted into the lower conduit 107 and fixed by screws. It should be noted that there are multiple sets of upper conduits 106 and corresponding lower conduits 107, which allows the upper box 1a to be securely connected to the lower box 1b by multiple screws.

[0037] Combination Figures 1 to 6 When playing music, the user can drive the drive gear 5 to rotate by turning the handle 7. The drive gear 5 drives the meshing driven gear 6 to rotate. The driven gear 6 transmits power to the front shaft 201 and the rear shaft 202 of the transmission shaft 2. The eccentric wheel 3 is driven to rotate up and down by the front shaft 201 and the rear shaft 202. When rotating upward, it drives the corresponding push rod 4 to move upward. The push rod 4 will cause the decorative parts to jump upward. At this time, the spring 8 corresponding to the push rod 4 is compressed. When the eccentric wheel 3 rotates downward, the spring 8 returns to its original deformation. Combined with the gravity of the push rod 4 and the decorative parts, the push rod 4 and the decorative parts move downward quickly, thus achieving the downward jump. In addition, according to the different styles and setting angles of the different eccentric wheels 3, the decorative parts can form staggered jumps or jumps of different amplitudes, so that the decorative parts present obvious rhythmic changes with the music playing, thereby better highlighting the emotion and atmosphere of the music theme, allowing the user to enjoy the visual experience while listening to the music.

[0038] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
