Description

Technical Field

[0001] The present invention relates to the technical field of violins, and specifically relates to an adjustable violin that prevents slipping. Background Art

[0002] A violin is a stringed instrument. It has a total of four strings. The vibration is generated by the friction between the strings and the bow, and then the vibration is conducted to the back plate through the sound post in the resonance box. The resonance generated by these parts produces a harmonious and bright sound of the violin;

[0003] During performance, the back plate of the violin is placed on the shoulder, and the head is tilted to press the chin rest on the back plate with the cheek. The violin is supported by the shoulder. The performer holds the neck of the violin with one hand to achieve stable holding of the violin, presses the strings rhythmically while holding the neck, and pulls the bow with the other hand to realize the performance of the violin;

[0004] The neck lengths of performers with different body shapes are different. At present, the heights of the chin rest and the back plate cannot be changed. For performers with longer necks, the neck needs to be bent excessively to clamp the back plate. The height of the chin rest directly affects the comfort of the performer's neck. The chin rests on the market are not reasonable enough. In addition, the arm supporting the neck of the violin is suspended. After a long time, it will cause soreness and is likely to cause the violin to slip, directly affecting the performance ability display of the performer. The existing violins still need to be further improved. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems that the existing chin rest cannot adjust the height according to the neck length of the performer and the holding of the violin is prone to fatigue.

[0006] The present invention realizes the above purpose through the following technical solutions. An adjustable violin that prevents slipping includes a violin and a chin rest. A lifting mechanism is installed on the front side of the violin, and the top end of the lifting mechanism is connected to the chin rest by screws. A supporting mechanism is installed at the bottom end of the violin;

[0007] The lifting mechanism includes two outer cylinders installed on the front side of the violin. A number of positioning holes are equidistantly arranged from top to bottom on the opposite surfaces of the two outer cylinders. An inner cylinder that can slide up and down is inserted into the inner cavity of the outer cylinder. A base is installed at the top end of the inner cylinder. The top end of the base is locked to the bottom end of the chin rest by screws. A guide rod is installed in the inner cavity of the base along the front-rear direction. Sliders are sleeved on the front and rear ends of the outer wall of the guide rod. One end of a support rod is installed at the bottom end of the slider. A positioning pin is installed at the other end of the slider, and the inner side of the positioning pin is inserted into the inner cavity of the positioning hole. A spring is sleeved on the outer wall of the guide rod, and the end of the spring is fixedly connected to the inner side of the slider. A turntable is installed at the center position of the top end of the inner cavity of the base through a bearing. One end of a first connecting rod is connected to the left and right ends of the lower surface of the turntable through a pin shaft, and the other end of the first connecting rod is connected to the top end of the slider through a pin shaft.

[0008] Specifically, the inner shape of the positioning pin is arc-shaped.

[0009] Specifically, the two first connecting rods rotate 180 degrees relative to the center point of the turntable and coincide.

[0010] Specifically, the support mechanism includes a suction cup installed at the bottom end of the violin. One end of a connecting rod is connected to the bottom end of the suction cup through a pin shaft, and the other end of the connecting rod is installed with a support assembly.

[0011] Specifically, the support assembly includes a first box body installed at the bottom end of the connecting rod. A slideway is opened at the bottom end of the inner cavity of the first box body. A screw rod is installed at the front side of the inner cavity of the first box body through a bearing. The bottom end of the screw rod extends out of the lower surface of the first box body and is installed with a knob. A driving block is screwed on the outer wall of the screw rod. One end of a second connecting rod is connected to the rear side of the driving block through a pin shaft. The top end of the inner cavity of the first box body is connected to a second box body through a pin shaft. The other end of the second connecting rod is connected to the rear bottom end of the inner cavity of the second box body through a pin shaft. A limiting block inserted into the inner cavity of the slideway is installed at the front side of the bottom end of the second box body.

[0012] Specifically, silicone pads with rough surfaces are bonded to the front side of the first box body and the rear side of the second box body.

[0013] Specifically, the slideway is arc-shaped and closed at both ends.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. When pulling the pull rod outwards, through the cooperation of the turntable and the first connecting rod, the two sliders can move outwards along the guide rod, prompting the support rod to drive the positioning pin out of the positioning hole, realizing the separation of the inner cylinder from the fixed state of the outer cylinder. The inner cylinder can slide on the outer cylinder. After changing the height of the chin rest, the spring pulls the slider inwards under its own pulling force, and the positioning pin is inserted into the positioning hole at the corresponding height to position the moved inner cylinder. Therefore, the height of the chin rest can be adjusted according to the neck length of the performer, making the performer more comfortable when clamping the back plate of the violin and improving the performance duration.

[0016] 2. By manipulating the knob to rotate the screw rod clockwise or counterclockwise, the screw rod drives the moving block to move upwards or downwards through the thread rotation force, and then the second connecting rod pulls the second box body to move forwards or backwards. The included angle between the first box body and the second box body becomes smaller or larger. Place the first box body under the armpit rib, and the second box body supports the upper arm of the performer. During the performance, it can provide support for the arm, prevent the performer's arm from hanging in the air and causing soreness, and at the same time improve the stability of the violin fixation and prevent it from slipping, making it easier for the performer to show their performance ability.

Detailed implementation manners

[0024] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the preferred implementation schemes of the present invention are further described below in conjunction with the detailed implementation manners and the attached drawings.

[0025] Please refer to Figure 1-6 , the present invention provides an adjustable violin that prevents slipping, including a violin 1 and a chinrest 3. A lifting mechanism 2 is installed on the front side of the violin 1, and the top end of the lifting mechanism 2 is connected to the chinrest 3 by screws. A support mechanism 4 is installed at the bottom end of the violin 1;

[0026] The lifting mechanism 2 includes two outer cylinders 21 installed on the front side of the violin 1. The up-and-down movement of the shoulder rest 3 is realized through the cooperation of the outer cylinder 21 and the inner cylinder 23. A number of positioning holes 22 are equidistantly arranged from top to bottom on the opposite surfaces of the two outer cylinders 21. The inner cavity of the outer cylinder 21 is inserted with an inner cylinder 23 that can slide up and down. The top end of the inner cylinder 23 is installed with a base 24. The top end of the base 24 and the bottom end of the shoulder rest 3 are locked by screws. A guide rod 25 is installed in the inner cavity of the base 24 along the front-rear direction. The outer wall of the guide rod 25 is rectangular to ensure that the slider 26 does not rotate when moving linearly. Both the front and rear ends of the outer wall of the guide rod 25 are sleeved with sliders 26. One end of a support rod 27 is installed at the bottom end of the slider 26. The other end of the slider 26 is installed with a positioning pin 28, and the inner side of the positioning pin 28 is inserted into the inner cavity of the positioning hole 22 to fix the inner cylinder 23 to the inner wall of the outer cylinder 21. A spring 29 is sleeved on the outer wall of the guide rod 25, and the end of the spring 29 is fixedly connected to the inner side of the slider 26. The spring 29 is a torsion spring that produces elastic deformation when stretched or compressed and returns to its initial state after the external force is removed. The two sliders 26 can move inward by the pulling force of the spring 29. A turntable 210 is installed at the center position of the top end of the inner cavity of the base 24 through a bearing. One end of each of the first connecting rods 211 is connected to the lower surface of the turntable 210 through a pin shaft at the left and right ends, and the other end of the first connecting rod 211 is connected to the top end of the slider 26 through a pin shaft.

[0027] As a preferred solution, furthermore, the inner side shape of the positioning pin 28 is arc-shaped, so that the inner surface area of the positioning pin 28 increases from small to large, which is beneficial for the positioning pin 28 to be inserted into the inner cavity of the positioning hole 22.

[0028] As a preferred solution, furthermore, the two first connecting rods 211 overlap by rotating 180 degrees relative to the center point of the turntable 210. When the turntable 210 rotates, the two first connecting rods 211 will swing in opposite directions, aiming to realize the synchronous inward or outward movement of the two sliders 26.

[0029] As a preferred solution, furthermore, the support mechanism 4 includes a suction cup 41 installed at the bottom end of the violin 1. The suction cup 41 is suctioned on the bottom back plate of the violin 1 to connect the support assembly 43 to the violin 1. One end of a connecting rod 42 is connected to the bottom end of the suction cup 41 through a pin shaft. The other end of the connecting rod 42 is installed with a support assembly 43. The connecting rod 42 is a telescopic rod to adjust the distance between the violin 1 and the support assembly 43.

[0030] As a preferred solution, further, the support component 43 includes a first box body 431 installed at the bottom end of the connecting rod 42. A slideway 432 is formed at the bottom end of the inner cavity of the first box body 431. The second box body 437 is limited by the cooperation of the slideway 432 and the limit block 438 to prevent the second box body 437 from moving beyond the limit and detaching from the first box body 431. The first box body 431 is used to abut against the rib of the performer. A screw rod 433 is installed at the front side of the inner cavity of the first box body 431 through a bearing. When the screw rod 433 rotates clockwise or counterclockwise, the threaded rotation force of the screw rod 433 drives the driving block 435 to move upward or downward. Further, the second connecting rod 436 pulls the second box body 437 to swing forward or backward. The bottom end of the screw rod 433 extends out of the lower surface of the first box body 431 and is installed with a knob 434. The outer wall of the screw rod 433 is screwed with a driving block 435. One end of the second connecting rod 436 is connected to the rear side of the driving block 435 through a pin shaft. The top end of the inner cavity of the first box body 431 is connected to the second box body 437 through a pin shaft. The second box body 437 is used to support the upper arm of the performer. The other end of the second connecting rod 436 is connected to the bottom rear side of the inner cavity of the second box body 437 through a pin shaft. A limit block 438 inserted into the inner cavity of the slideway 432 is installed at the front side of the bottom end of the second box body 437.

[0031] As a preferred solution, further, silicone pads with rough surfaces are bonded to the front side of the first box body 431 and the rear side of the second box body 437, increasing the friction between the first box body 431 and the second box body 437 and the clothes of the performer to prevent falling off. At the same time, the silicone pads have elasticity to prevent pressure sores on the skin of the performer.

[0032] As a preferred solution, further, the slideway 432 is arc-shaped and closed at both ends, ensuring that the limit block 438 can slide along the slideway 432 without affecting the normal swing of the second box body 437.

[0033] Working principle:

[0034] Step 1, adjust the height of the chin rest 3 according to the neck length of the performer. Pull the pull rod 212 outwards, prompting the slider 26 and the first connecting rod 211 on the right side to move outwards. Since the two first connecting rods 211 are connected to the turntable 210, the two sliders 26 are driven to move outwards simultaneously by the linkage of the two first connecting rods 211. The support rod 27 moves with the slider 26 until the positioning pin 28 moves out of the positioning hole 22, releasing the fixation between the inner cylinder 23 and the outer cylinder 21. The inner cylinder 23 slides on the inner wall of the outer cylinder 21. Adjust the height of the chin rest 3 to an appropriate position, release the pull rod 212, and the spring 29 pulls the two sliders 26 to move inwards simultaneously under its own pulling force. Further, the positioning pin 28 moves inwards and inserts into the positioning hole 22 at the corresponding position to position the adjusted chin rest 3, completing the height adjustment of the chin rest 3, making the chin rest 3 suitable for performers with different neck lengths to use and preventing neck soreness;

[0035] Step 2: Drive the screw 433 to rotate clockwise or counterclockwise through the knob 434. The threaded rotation force of the screw 433 drives the driving block 435 to move upward or downward. Further, the second connecting rod 436 pulls the second box body 437 to move forward or backward. The maximum angle between the first box body 431 and the second box body 437 becomes smaller or larger until the angle is suitable for the performer to clamp under the armpit. Press the first box body 431 against the rib part under the armpit, and press the upper arm holding the neck of the violin on the second box body 437 to support the whole arm. The connecting rod 42 realizes the support of the violin 1, which can not only prevent the arm from being suspended and causing soreness, but also ensure the flexibility of the fingers during playing.

[0036] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
