Description

Technical Field

[0001] This utility model relates to the field of cello soundposts, specifically an adjustable soundpost positioning device for cellos. Background Technology

[0002] The soundpost is a small wooden post inside a violin-like instrument, located between the top and back plates. It plays a crucial role in the instrument's sound transmission, resonance, and structural stability. During the installation of the soundpost, since the operator cannot directly reach inside the cello, tools are needed to install it. To ensure accurate installation, the soundpost's position must be precisely determined before installation.

[0003] Currently, soundposts are typically positioned and installed using soundpost hooks. However, soundpost hooks are not suitable for inexperienced users, as they may lead to inaccurate installation or the soundpost being pulled out when the hook is removed, resulting in installation failure. Therefore, an adjustable soundpost positioning device for cellos is proposed to address these issues. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and avoid the inconvenience of installing soundposts, this utility model proposes an adjustable soundpost positioning device for cellos.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable soundpost positioning device for cellos, including a column, a support plate fixedly connected to the bottom end of the column, a measuring component provided on the surface of the top of the column, an installation component provided on the surface of the bottom of the column, and a control switch provided inside the top of the column. The measuring component includes a connecting ring that is slidably connected to the top surface of the column, and a rotating plate that is rotatably connected to the surface of the connecting ring. The surface of the rotating plate is provided with a scale line.

[0006] Preferably, the mounting assembly includes a vertical groove formed on the bottom surface of the column, a vertical rod fixedly connected inside the groove, a hollow rod slidably connected to the surface of the vertical rod, a screw threaded to the top of the hollow rod, a solid rod slidably connected to the left side of the hollow rod, a screw threaded to the top left side of the hollow rod, a telescopic rod fixedly connected to the left side surface of the solid rod, a scale line 2 on the surface of the solid rod, a lower guide rail fixedly connected to the end of the solid rod away from the hollow rod, a crossbar fixedly connected to the left side of the lower guide rail, sliders on both the front and rear sides of the crossbar, damping blocks fixedly connected to the inside of the sliders, a buffer spring fixedly connected to the end of the slider near the middle of the lower guide rail, a clamping block fixedly connected to the left end face of the slider, and a rubber block fixedly connected to the inner wall of the clamping block.

[0007] Preferably, the top end of the lower guide rail is fixedly connected to the upper guide rail, an electromagnetic block is slidably connected inside the upper guide rail, and a pull rope is fixedly connected to the surface of the electromagnetic block.

[0008] Preferably, the mounting components are arranged in two sets, symmetrically arranged on the surface of the column, and the two clamping blocks can stably clamp the sound column.

[0009] Preferably, the first screw has its side near the interior of the hollow rod in contact with the surface of the vertical rod, and the position of the hollow rod in the vertical direction can be limited by the first screw. The bottom end of the second screw is in contact with the surface of the solid rod, and the length of the solid rod extending out of the hollow rod can be limited by the second screw.

[0010] Preferably, the upper and lower ends of the telescopic rod are fixedly connected to the upper and lower solid rods respectively, so that the telescopic rod can ensure that the upper and lower solid rods move at the same distance.

[0012] Preferably, the near ends of the two electromagnetic blocks are opposite magnetic poles. The electromagnetic blocks are electrically connected through a microcontroller and a control switch. The end of the pull rope away from the electromagnetic block is fixedly connected to the surface of the slider. When the two electromagnetic blocks are energized by the control switch, they will attract each other. At this time, the electromagnetic blocks will pull the slider through the pull rope, thereby causing the two sliders to move away from each other and release the sound column.

[0013] The advantages of this utility model are: This utility model uses two sets of clamping blocks to stably clamp the sound column. The extension stroke of the clamping blocks can be adjusted vertically by the scale line to stably clamp the sound column to the predetermined installation position.

[0018] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail as follows: This application discloses an adjustable soundpost positioning device for cellos. (Refer to...) Figure 1 An adjustable soundpost positioning device for cello includes a column 1, a support plate 2 fixedly connected to the bottom end of the column 1, a measuring component 3 provided on the top surface of the column 1, an installation component 4 provided on the bottom surface of the column 1, and a control switch 5 provided inside the top of the column 1. Reference Figure 2 The measuring component 3 includes a connecting ring 31 that is slidably connected to the top surface of the column 1. A rotating plate 32 is rotatably connected to the surface of the connecting ring 31. A scale line 33 is provided on the surface of the rotating plate 32.

[0019] Reference Figures 3-6The mounting component 4 includes a vertical groove 411 formed on the bottom surface of the column 1. A vertical rod 412 is fixedly connected inside the vertical groove 411. A hollow rod 421 is slidably connected to the surface of the vertical rod 412. A screw 422 is threadedly connected to the top of the hollow rod 421. A solid rod 423 is slidably connected to the left side inside the hollow rod 421. A screw 424 is threadedly connected to the top left side of the hollow rod 421. The side of the screw 422 closest to the inside of the hollow rod 421 is adapted to contact the surface of the vertical rod 412. 2. The position of the hollow rod 421 in the vertical direction is defined. The bottom end of the screw 424 is adapted to contact the surface of the solid rod 423. The length of the solid rod 423 extending out of the hollow rod 421 can be defined by the screw 424. A telescopic rod 425 is fixedly connected to the left side surface of the solid rod 423. The upper and lower ends of the telescopic rod 425 are fixedly connected to the upper and lower solid rods 423 respectively. The telescopic rod 425 can ensure that the upper and lower solid rods 423 have the same stroke. The surface of the solid rod 423 is provided with a scale line 426. A solid rod 423 is fixedly connected to a lower guide rail 431 at the end away from the hollow rod 421. A crossbar 432 is fixedly connected to the inside of the left side of the lower guide rail 431. Slider blocks 433 are provided on both the front and rear sides of the surface of the crossbar 432. A damping block 434 is fixedly connected inside the slider 433. A buffer spring 435 is fixedly connected to the end of the slider 433 near the middle of the lower guide rail 431. The slider 433 is slidably connected inside the lower guide rail 431. The damping block 434 is slidably connected to the surface of the crossbar 432. The buffer spring 435 is wound around the surface of the crossbar 432. The end of the buffer spring 435 away from the slider 433 is fixedly connected to the inner wall of the lower guide rail 431. A clamping block 436 is fixedly connected to the left end face of the slider 433. There are two sets of mounting components 4, which are symmetrically arranged on the surface of the column 1. The two clamping blocks 436 can stably clamp the sound column. A rubber block 437 is fixedly connected to the inner wall of the clamping block 436.

[0020] Reference Figures 5-6 The top of the lower guide rail 431 is fixedly connected to the upper guide rail 441. An electromagnetic block 442 is slidably connected inside the upper guide rail 441. A pull rope 443 is fixedly connected to the surface of the electromagnetic block 442. The near ends of the two electromagnetic blocks 442 are opposite magnetic poles. The electromagnetic blocks 442 are electrically connected through a microcontroller and a control switch 5. The end of the pull rope 443 away from the electromagnetic block 442 is fixedly connected to the surface of the slider 433. When the two electromagnetic blocks 442 are energized by the control switch 5, they will attract each other. At this time, the electromagnetic blocks 442 will pull the slider 433 through the pull rope 443, thereby causing the two sliders 433 to move away from each other and release the sound column.

[0021] Working principle: The operator first inserts the soundpost 1 and hollow rod 421 through the f-hole of the cello and places them vertically on the bottom wall of the cello. Then, the operator pushes the adjusting connecting ring 31 to adjust its position, and then rotates the rotating plate 32 to make it fit against the top of the cello. At this time, the depth to which the soundpost needs to be installed can be observed through the scale line 33. Then, the soundpost 1 is removed, and the solid rod 423 is pulled outward to extend it beyond the hollow rod 421. With the extension rod 425 connected, both solid rods 423 extend simultaneously. During the extension of the solid rods 423, the scale line 426 on their surface can be observed. Then, the measurement is made according to the scale line 33. Adjust the extension length of the solid rod 423 according to the data of scale line 426 until the solid rod 423 extends to the predetermined position. Then, rotate screw 424 to make it abut against the top of the solid rod 423, thereby limiting the position of the solid rod 423. Then, adjust the position of the two hollow rods 421 according to the length of the soundpost and the height of the cello, so that the two hollow rods 421 are positioned between the upper and lower ends of the soundpost and can extend into the inside of the cello. Then, rotate screw 422 to make it abut against the surface of the vertical rod 412, at which point the position of the two hollow rods 421 is limited. The preparation work is now complete.

[0022] Next, the soundpost is placed between the two clamping blocks 436. At this time, the two clamping blocks 436 will clamp the soundpost under the action of the rebound force of the buffer spring 435. Under the action of the friction of the rubber block 437, the two clamping blocks 436 can clamp the soundpost more stably. Then, the operator puts the upright 1, solid rod 423 and soundpost through the f hole into the inside of the cello until the upright 1 and support plate 2 abut against the bottom wall of the cello. At this time, the upright 1 is rotated and the rotating plate 32 is placed on the top of the outside of the cello. Since the rotating plate 32 and hollow rod 421 face the same direction, the position of the rotating plate 32 can be observed to adjust the position of the hollow rod 421. Thus, the position of the soundpost on the left side of the hollow rod 421 is also placed. At this time, the upper and lower ends of the soundpost abut against the inner walls of the upper and lower ends of the cello. That is, the soundpost installation is now complete.

[0023] The operator then presses control switch 5, which powers the electromagnetic block 442 via the microcontroller. At this time, the two electromagnetic blocks 442 attract each other and pull the pull rope 443. The pull rope 443 then pulls the slider 433 to move along the surface of the crossbar 432 towards the edge of the guide rail 431. The two sliders 433 then move the two clamping blocks 436 away from each other, causing the two clamping blocks 436 to release the sound column. The column 1 can then be pushed to move inside the f-hole, causing the two clamping blocks 436 to move away from the sound column. The column 1 can then be removed through the f-hole.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
