Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to an improved guitar string knob. Background Art

[0002] Guitar is a plucked instrument that produces sound by plucking the guitar strings with fingers to generate vibrations. The guitar mainly produces sound through the guitar strings, which are the scale lines. The scale lines are an important part of the guitar. Different scale lines are made of a variety of different elastic materials and can produce different styles of sound. Since the guitar produces sound by plucking the strings, the tightness of the strings will affect the accuracy of the guitar's sound. Guitar pegs are installed on the guitar, and the guitar strings are inserted and wrapped around the guitar pegs. When the guitar strings are loose or too tight, the tightness of the strings can be adjusted by rotating the guitar pegs, making it more convenient and simple to adjust the tightness of the guitar strings. At the same time, they can be adjusted and tested at any time, making tuning less difficult.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, it still has certain defects: when adjusting the existing guitar string knobs, the string knobs need to be twisted to rotate on the guitar fender. When adjusting thicker strings that need to be adjusted more tightly, a large torque needs to be applied to the string knobs. If the number of turns of the strings that are wound is small, it is easy for the strings to fall out of the perforations of the string knobs under the action of excessive torque, thereby causing the string knobs to rotate idly and being unable to effectively adjust the tightness of the strings. Utility Model Content

[0004] The utility model aims to provide an improved guitar string knob which has good string fixing effect and prevents the strings from falling out, in view of the defects and shortcomings of the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an improved guitar string knob, comprising a twisting cap and a winding column fixedly arranged below the twisting cap, the winding column comprising a column body arranged below the twisting cap and a through hole penetrating the column body, a downward pressure column with a top end penetrating the twisting cap is also slidably provided in the column body, the bottom end of the downward pressure column penetrates and extends into the through hole, when adjusting the tightness, the twisting cap is twisted to synchronously press the downward pressure column, so that the downward pressure column is pressed into the through hole to further squeeze and fix the strings.

[0006] A further improvement is that: a hexagonal fixing hole is provided on the top surface of the screw cap.

[0007] A further improvement is that an upper protrusion is also provided at the bottom of the perforated inner wall.

[0008] A further improvement is that a hollow tube is provided at the bottom of the lower pressure column, and an adsorption block connected to the inner cavity of the hollow tube is provided at the bottom end of the hollow tube.

[0009] A further improvement is that the adsorption block includes a tray arranged at the bottom end of the hollow tube and an extrusion sheet arranged on the bottom surface of the tray, the bottom of the extrusion sheet is provided with a suction block penetrating the extrusion sheet, and the top of the inner wall of the tray is also penetrated by a one-way tube connected to the inner cavity of the hollow tube.

[0010] A further improvement is that an elastic bracket is provided between the inner wall of the extrusion sheet and the inner wall of the tray.

[0011] A further improvement is that a suction cup connected to the inner cavity of the suction block is also provided at the bottom of the suction block.

[0012] A further improvement is that the one-way tube includes a discharge pipe penetrating the top of the inner wall of the tray and communicating with the inner cavity of the hollow tube, and an inner retraction block arranged on the inner wall of the discharge pipe, and a sealing block is also attached to the upper surface of the inner retraction block.

[0013] A further improvement is that a reset spring is provided between the top surface of the sealing block and the inner wall of the discharge pipe.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the utility model is in use, if a large torque is needed to adjust the tightness, the pressure column can be pressed down synchronously by a tool or manually while being twisted, so that the strings are pressed down by the pressure column while being twisted, so that the strings are pressed tightly by the pressure column and the inner wall of the perforation, and a strong friction force is generated between the strings and the inner wall of the perforation, preventing them from falling out of the perforation, avoiding the phenomenon of idling of the string buttons, and ensuring the tightness adjustment effect of the strings.

[0019] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0020] See also Figure 1-3 As shown, the technical solution adopted in this specific embodiment is: an improved guitar string knob, comprising a twisting cap 1 and a winding post 2 fixedly arranged below the twisting cap 1, the winding post 2 comprising a column 21 arranged below the twisting cap 1 and a through hole 22 penetrating the column 21, a pressing post 24 with a top penetrating the twisting cap 1 is also slidably arranged inside the column 21, and the bottom end of the pressing post 24 penetrates and extends into the through hole 22. When adjusting the tightness, the twisting cap 1 is twisted to press the pressing post 24 synchronously, so that the pressing post 24 is pressed into the through hole 22 to further squeeze and fix the strings. When in use, the winding post 2 is inserted into the end of the guitar body, and the strings fixed at one end are inserted into the through hole 22, and then the strings are pulled out from the through hole 22. The screw cap 1 is inserted into and wrapped around the outer wall of the cylinder 21. When the tightness of the guitar strings needs to be adjusted, the screw cap 1 can be turned to synchronously drive the cylinder 21 of the winding cylinder 2 to rotate, thereby tightening or loosening the guitar strings. When a large torque is needed to adjust the strings, the pressing column 24 is pressed internally synchronously, so that the pressing column 24 slides downward along the cylinder 21 and protrudes from the inner cavity of the perforation 22, contacts the surface of the string, and applies pressure to the string, so that the string is pressed between the inner cavity of the perforation 22 and the pressing column 24, generating a strong friction force, and then when the string knob is twisted with a large torque, the string is not easy to fall out of the perforation 22, avoiding the phenomenon of the string knob idling, thereby ensuring the tightness adjustment effect of the string;

[0021] The top surface of the screw cap 1 is provided with a hexagonal fixing hole 3, which is convenient for connecting the hexagonal stud and can be connected to an external torque device to more conveniently perform large torque adjustment;

[0022] The bottom of the inner wall of the through hole 22 is also provided with an upper protrusion 23, which is conducive to pressing the surface of the string more tightly and further preventing the string from being pulled out;

[0023] A hollow tube 25 is provided at the bottom of the lower pressure column 24, and an adsorption block 26 connected to the inner cavity of the hollow tube 25 is provided at the bottom end of the hollow tube 25. The adsorption block 26 includes a tray 31 arranged at the bottom end of the hollow tube 25 and an extrusion sheet 32 ​​arranged on the bottom surface of the tray 31. A suction block 34 penetrating the extrusion sheet 32 ​​is provided at the bottom of the extrusion sheet 32. A one-way tube connected to the inner cavity of the hollow tube 25 is also penetrated at the top of the inner wall of the tray 31. The one-way tube includes a discharge pipe 36 penetrating the top of the inner wall of the tray 31 and connected to the inner cavity of the hollow tube 25, and an inner retraction block 37 arranged on the inner wall of the discharge pipe 36. The upper surface of the inner retraction block 37 is also attached with a sealing block 34. 8. When the lower pressure column 24 is pressed down, the adsorption block 26 is pressed on the upper surface of the string synchronously, so that the extrusion sheet 32 ​​and the suction block 34 of the adsorption block 26 are squeezed and deformed, which leads to the reduction of the inner space formed by the extrusion sheet 32 ​​and the tray 31, thereby causing the gas to be discharged from the discharge pipe 36, and the closing block 38 is squeezed open by the air pressure to discharge the gas into the inner cavity of the hollow tube 25. At the same time, when the gas flows back, the closing block 38 is quickly pressed onto the inner block 37 by the gravity of the closing block 38 and the reverse thrust of the gas, so that the discharge pipe 36 is closed, and then suction is generated at the suction block 34. In the process of compacting the string, it is adsorbed synchronously, making it less likely to slide;

[0024] An elastic bracket 33 is also provided between the inner wall of the extrusion sheet 32 ​​and the inner wall of the tray 31, which is beneficial to maintaining the compression resistance of the extrusion sheet 32 ​​so that the pressure can be better transmitted to the strings;

[0025] The bottom of the suction block 34 is also provided with a suction cup 35 which is connected to the inner cavity of the suction block 34, which is beneficial to increase the contact friction with the surface of the string and make the adsorption area larger, so that the string is less likely to slide;

[0026] A reset spring 39 is provided between the top surface of the sealing block 38 and the inner wall of the discharge pipe 36, which is conducive to faster recovery of the sealing block 38, thereby preventing gas from entering, thereby generating greater suction.

[0027] The working principle of the utility model is as follows: when the utility model is used, the winding post 2 is inserted into the end of the guitar body, and the string fixed at one end is inserted into the through hole 22, and passes through the through hole 22 and is wound around the outer wall of the post 21. When the tightness of the guitar strings needs to be adjusted, only the twisting cap 1 is twisted to make the twisting cap 1 synchronously drive the post 21 of the winding post 2 to rotate, thereby tightening or loosening the guitar strings. When a large torque is needed to adjust the strings, the pressing post 24 is pressed internally at the same time, so that the pressing post 24 slides downward along the post 21 and protrudes from the inner cavity of the through hole 22, contacts the surface of the string, and applies pressure to the string, thereby making the string pressed between the inner cavity of the through hole 22 and the pressing post 24, generating a strong friction force, and then when the string knob is twisted with a large torque, the string is not easy to fall out of the through hole 22, thereby avoiding the phenomenon of the string knob idling, and ensuring the tightness adjustment effect of the string.
