Description

Technical Field

[0001] The present invention relates to the technical field of teaching auxiliary appliances, and in particular to a violin fingering practice auxiliary device. Background Art

[0002] The violin is a four-stringed bowed string instrument widely used in classical music, folk music, and popular music. The violin's strings vibrate through the friction between the bow and the strings. This vibration is transmitted through the sound post inside the resonance box (the instrument's body) to the backboard, producing a harmonious and bright sound.

[0003] The movable tuning knobs are slidably mounted on the strings. Therefore, this solution can only be applied to violin models and cannot produce real sounds. As a result, the practice effect is poor, and the tuning knobs still cannot keep the fingers upright when pressing the strings. In view of this, it is necessary to improve the existing violin fingering practice device to improve the practice effect and keep the fingers upright when pressing the strings. To address the above technical issues, a violin fingering auxiliary practice device is disclosed in Publication No. CN214279264U. Firstly, the device can be detachably mounted on the violin fingerboard and can be directly used on a real violin, enabling authentic sound production and playing, greatly improving the practice effect. Secondly, the practitioner can place their fingers in the notches, which can support them and keep them in an upright position, further improving the standardization of fingering and facilitating the training of qualified fingering. In addition, the device is easy to use. The above-mentioned prior art also has the following shortcomings: when practicing fingering with a violin, it is impossible to always carry the violin with you, so the method adopted in the above-mentioned prior art needs to be adapted to the violin for fingering practice, which leads to limitations in actual use. Summary of the Invention

At the same time, the auxiliary device is small in size and can be carried around, so fingering practice can be performed in different environments, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a violin fingering practice auxiliary device, comprising a base; The top of the base is provided with a pressing mechanism for adjusting the pressing force of fingering practice, the outer side of the pressing mechanism is provided with a limiting mechanism for controlling the pressing of the pressing mechanism, and the bottom of the pressing mechanism is provided with a moving mechanism for adjusting the spacing between the pressing mechanisms; The pressing mechanism includes: A support assembly is provided on the top of the base, wherein a transmission assembly and a pressing assembly connected to the transmission assembly are slidably connected inside the support assembly; A connecting assembly is provided at the bottom end of the transmission assembly, and an elastic assembly for elastic connection is provided on the outer side of the connecting assembly; The moving mechanism includes: The sliding component is arranged on the top of the base, and the bottom of the sliding component is provided with a locking component.

[0007] Exemplarily, the transmission assembly includes: The vertical rod is slidably connected to the connecting pipe and the top of the base, and the top of the vertical rod is fixedly installed with a mounting plate.

[0008] Exemplarily, the pressing component includes: The rubber pad is fixedly mounted on the top of the mounting plate, and a groove is formed on the top of the rubber pad.

[0009] Exemplarily, the connection component includes: The circular plate is fixedly mounted on the bottom end of the vertical rod, and the inner side wall of the circular plate is slidably connected with a first screw rod and a sleeve plate threadedly connected to the first screw rod.

[0010] Exemplarily, the elastic component includes a spring; The spring is welded to the bottom of the circular plate, and a connecting seat located on the top surface of the sleeve plate is welded to the bottom of the spring. The connecting seat and the first screw are slidably arranged.

[0012] Exemplarily, the locking assembly includes: The second threaded rod is fixedly mounted on the bottom of the connecting pipe, and the outer side of the second threaded rod is threadedly connected to a threaded sleeve.

[0013] Exemplarily, the limiting mechanism includes: A connecting block is fixedly mounted on the surface of the connecting pipe, wherein the outer side of the connecting block is rotatably connected to a vertical plate and a rotating plate fixed to the top of the vertical plate; The top plate is rotatably connected to the top of the inner side of the vertical plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention achieves the advantage of unrestricted fingering practice through the setting of the pressing mechanism. Based on the advantages of the auxiliary device being small in size and easy to carry, fingering practice can be performed when going out and in different environments. It is not only convenient to use and practice, but also the control of the finger pressing force during the practice process can be adjusted as needed to improve the effect of the practice. The circular plate compression spring can be driven to perform fingering practice by pressing down on the rubber pad, and each time the pressing force is released, it can be reset according to the elasticity of the spring.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The present invention provides a violin fingering practice auxiliary device, comprising a base 1; like Figure 4 As shown, a pressing mechanism 2 for adjusting the pressing force of fingering practice is provided on the top of the base 1, a limiting mechanism 4 for controlling the pressing force of the pressing mechanism 2 is provided on the outside of the pressing mechanism 2, and a moving mechanism 3 for adjusting the spacing between the pressing mechanisms 2 is provided at the bottom of the pressing mechanism 2; The pressing mechanism 2 includes: A support assembly is provided on the top of the base 1, wherein a transmission assembly and a pressing assembly connected to the transmission assembly are slidably connected inside the support assembly; A connecting assembly is provided at the bottom end of the transmission assembly, and an elastic assembly for elastic connection is provided on the outer side of the connecting assembly; The moving mechanism 3 includes: The sliding assembly is arranged on the top of the base 1, and a locking assembly is arranged on the bottom of the sliding assembly.

[0022] Preferred; like Figure 5 As shown, the support assembly includes: The connecting tube 21 is slidably connected to the top of the base 1. A baffle 22 is fixedly installed on the inner wall of the connecting tube 21. The connecting tube 21 is used to support the internal components to assist in completing the pressing exercise, and the baffle 22 is used to block and limit the baffle 22.

[0023] further; like Figure 5 As shown, the transmission assembly includes: The vertical rod 23 is slidably connected to the top of the connecting pipe 21 and the base 1. A mounting plate 24 is fixedly installed on the top of the vertical rod 23. The vertical rod 23 plays a transmission role during pressing, and the mounting plate 24 can support the downward pressing component.

[0024] in; like Figure 5 As shown, the pressing assembly includes: The rubber pad 25 is fixedly mounted on the top of the mounting plate 24. A groove 26 is provided on the top of the rubber pad 25. The rubber pad 25 can improve the comfort of pressing and avoid finger fatigue caused by the pressing part being too hard. The groove 26 is helpful for preventing the fingertips from slipping when pressing.

[0025] Go one step further; like Figure 5 As shown, the connection components include: The circular plate 27 is fixedly mounted on the bottom end of the vertical rod 23. The inner side wall of the circular plate 27 is slidably connected with a first screw 28 and a sleeve 29 threadedly connected to the first screw 28. The circular plate 27 can realize the downward thrust and can press the spring 210 for exercise. The first screw 28 can be threadedly adapted to the sleeve 29 so that the sleeve 29 can be threadedly rotated to adjust the position upward.

[0026] The bottom end of the first screw rod 28 is fixed to the bottom of the inner cavity of the connecting tube 21 .

[0027] in addition; like Figure 5 As shown, the elastic assembly includes a spring 210; The spring 210 is welded to the bottom of the circular plate 27. A connecting seat 211 located on the top surface of the sleeve 29 is welded to the bottom of the spring 210. The connecting seat 211 is slidingly arranged with the first screw 28. The elastic setting of the spring 210 can achieve a reset effect after fingering practice. The connecting seat 211 can assist in the installation and bearing of the spring 210. The connecting seat 211 and the sleeve 29 are in contact and the two are not fixed, which facilitates the subsequent upward adjustment of the sleeve 29 and compression of the spring 210.

[0028] When practicing fingering, the device needs to be held on the palm of the hand first, and then the corresponding fingers are placed on the top of the rubber pads 25 and the grooves 26. Then, several groups of rubber pads 25 and grooves 26 are pressed in sequence according to the required order to practice fingering. When pressing, when the fingers press the rubber pads 25 and the grooves 26, a downward thrust is generated, which further drives the vertical rod 23 to move downward. The vertical rod 23 is connected to the top of the connecting tube 21 in a through-type sliding connection, and is also connected to the baffle 22 in a through-type sliding connection. Therefore, it can prevent the vertical rod 23 from deflecting and ensure its stable downward movement. When the vertical rod 23 moves downward, it directly pushes the circular plate 27, which compresses the spring 210 downward. Then, the first screw 28 enters the interior of the vertical rod 23, and the two are in a sliding connection. This allows fingering practice. Due to the advantage of the overall small size of the device, it can be carried around in any environment for practice, without having to carry a violin with you at all times. When the pressing force required for fingering practice needs to be adjusted, the sleeve plate 29 needs to be rotated. The bottom of the surface and back of the connecting tube 21 are provided with operation holes, so the sleeve plate 29 can be directly rotated by fingers. The surface of the sleeve plate 29 is provided with anti-slip grooves, so a stable rotation effect is achieved. When the sleeve plate 29 is rotated, it moves upward due to the threaded relationship with the first screw 28. When moving upward, it directly pushes the connecting seat 211 to move upward. When the connecting seat 211 moves upward, it compresses the spring 210 until it reaches a preset height and the compression force of the spring 210 is sufficient. After adjustment, when pressing, the spring 210 is compressed to a preset state, so a greater pressing force is required to press and compress the spring 210 again, thereby achieving control over the pressing force during fingering practice.

[0029] Therefore, not only the effect of no restriction during fingering practice is achieved, but also the pressing force required during practice can be adjusted as needed and the pressing force intensity can be controlled, thereby improving the effect of fingering practice.

[0030] It is worth explaining; like Figure 6 As shown, the sliding assembly includes: The sliding hole 34 is opened at the top of the base 1, and the slider 31 is slidably connected inside the sliding hole 34. The sliding hole 34 is opened to adapt to the sliding of the slider 31, and the slider 31 plays a role of connecting the upper and lower parts. Its top surface is fixed to the connecting tube 21, and its bottom surface is fixed to the second threaded rod 32.

[0031] in; like Figure 6 As shown, the locking assembly includes: The second threaded rod 32 is fixedly installed on the bottom of the connecting pipe 21. The outer side of the second threaded rod 32 is threadedly connected to the threaded sleeve 33. The second threaded rod 32 is used to threadably adapt to the threaded sleeve 33. With the help of the threaded sleeve 33, a locking effect can be achieved when it is pressed against the base 1.

[0032] When the spacing between several groups of pressing mechanisms 2 needs to be adjusted, the threaded sleeve 33 can be rotated counterclockwise to make it contact and lock. Then, the connecting tube 21 can be directly pushed and pulled horizontally on the top of the base 1 to move, and the slider 31 can be driven to slide inside the sliding hole 34. When it slides to the preset position, it stops moving. Then, the threaded sleeve 33 can be rotated clockwise to make its top contact with the base 1 to complete the position locking operation.

[0033] Based on the above, this component can achieve the advantage of adjusting the distance between several groups of pressing mechanisms 2, and can achieve adaptive adjustment based on the size, length and required pressing position of different fingers to improve the adaptability during practice, and further improve the fit of the practice and the effect of the practice.

[0034] also; like Figure 7 As shown, the limiting mechanism 4 includes: The connecting block 41 is fixedly mounted on the surface of the connecting pipe 21. The outer side of the connecting block 41 is rotatably connected to a vertical plate 42 and a rotating plate 44 fixed to the top of the vertical plate 42. The top plate 43 is rotatably connected to the top of the inner side of the vertical plate 42 .

[0035] The connecting block 41 is used to realize the rotation support of the vertical plate 42, and the vertical plate 42 is used to realize the rotation support of the rotating plate 44. After adjustment, the rotating plate 44 can realize the pressure holding and limiting effect on the pressed rubber pad 25. At the same time, the top plate 43 can realize the blocking and limiting effect on the rotating plate 44 after rotation adjustment. like Figure 4 As shown, the state of the rotating plate 44 at this time is not adjusted. When the state after adjustment is as shown in FIG. Figure 7 As shown, secondly, the connecting pieces for rotation between the various components are connected by damping rotation; When rotation adjustment is required, the vertical plate 42 is first rotated counterclockwise to change from a vertical state to a horizontal state, and then the rotating plate 44 is rotated to change from the rotated horizontal state to a vertical state. The rubber pad 25 is then pressed using the above-mentioned pressing method until the mounting plate 24 contacts the top of the connecting tube 21. The vertical plate 42 is then rotated, causing the vertical plate 42 to rotate with the top plate 43 and position the top plate 43 on top of the rubber pad 25 and come into contact with it. Because the rotating plate 44 is blocked by the top plate 43 and is blocked by the top surface of the rubber pad 25, the rubber pad 25 cannot move upward when indirectly pushed by the spring 210, thereby limiting a single pressing mechanism 2. Based on the above-mentioned operation limiting the corresponding pressing mechanism 2, the restricted pressing mechanism 2 does not need to be pressed during practice, and the corresponding finger does not need to be practiced. The desired finger fingering can be practiced separately. Based on the above-mentioned finger fingering practice, the desired finger fingering practice can be selectively and controlled, thereby improving the effect and diversity of fingering practice.

[0036] at last; like Figure 2 and 3 As shown, a protection mechanism 5 for protection is provided on the outer side of the base 1, and the protection mechanism 5 includes; The rubber sleeve 51 is sleeved on the outer side of the base 1 . A rubber seat 52 is fixedly mounted on the bottom of the rubber sleeve 51 . An outer protective cover 53 is sleeved on the outer side of the rubber sleeve 51 .

[0037] The rubber sleeve 51 can be used to protect the base 1, and the rubber seat 52 is conducive to direct contact with the user's palm during operation. Due to its softness, it can avoid muscle damage to the palm during practice, thereby achieving a protective effect. The outer protective cover 53 is conducive to directly covering and protecting the pressing mechanism 2 and the limiting mechanism 4, avoiding damage when carrying and not in use, thereby improving the protective effect. When in use, it can be directly pulled out and then fingering practice can be carried out. Based on the above, the protection of the auxiliary device for fingering practice can be improved during use and non-use.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
