However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.
[0022] Embodiment 1, as Figures 1-4 shown, the present invention provides a tensioning and fixing device for guqin strings, including: a goose foot 1, a fixed plate 9 is fixedly connected to the outer surface of the goose foot 1 near the bottom, a plurality of first tooth blocks 10 are evenly and fixedly connected to the top of the fixed plate 9, a moving plate 11 is sleeved on the outer surface of the goose foot 1, a plurality of second tooth blocks 12 are evenly and fixedly connected to the bottom of the moving plate 11, a spring 6 is fixedly connected to the inner bottom of the goose foot 1, a sliding groove 4 is opened on the outer surface of the goose foot 1, and a card slot 5 is opened on the outer surface of the goose foot 1; a fixing component 2, the fixing component 2 is inserted into the inner surface of the goose foot 1, the fixing component 2 includes an insertion rod 201, a pressing plate 207 is fixedly connected to the bottom of the insertion rod 201, a positioning rod 206 is fixedly connected to the outer surface of the insertion rod 201, the moving plate 11 is located above the fixed plate 9, the positions of the first tooth block 10 and the second tooth block 12 are matched, limiting grooves 3 are symmetrically opened on the outer surface of the goose foot 1, limiting blocks 13 are symmetrically and fixedly connected to the inner surface of the moving plate 11, the outer surface of the limiting block 13 is inserted and connected with the inner surface of the limiting groove 3, a rotating ring 14 is rotatably connected to the top of the moving plate 11, a knob 202 is fixedly connected to the top of the insertion rod 201, a plurality of connecting rods 203 are evenly and fixedly connected to the bottom of the knob 202, a moving ring 204 is fixedly connected between the lower end faces of the plurality of connecting rods 203, the moving ring 204 is fixedly connected with the rotating ring 14, a winding tube 205 is fixedly connected to the outer surface of the moving ring 204, the sliding groove 4 and the card slot 5 are both matched with the position of the positioning rod 206, and the positioning rod 206 is located near the upper side inside the sliding groove 4.
[0023] The effect achieved by the entire embodiment 1 is that when the strings of the guqin are replaced, one end of the string is tied with a dragonfly knot at the Yueshan of the head of the guqin, and then fixedly connected with the velvet button. The velvet button head is inserted from the velvet button hole of the guqin bottom plate until the guqin surface is flush with the Yueshan, and then the tail end of the string with the fly head is inserted into the velvet button and pulled to the position flush with the Yueshan, and then the string is closely attached to the guqin surface, bypassed by the dragon gum to the goose foot 1 for winding and fixing. When the string is sent to the position of the goose foot 1, it is necessary to tighten the string and align the spacing of the strings. During operation, the string is sent to the position between the fixed plate 9 and the movable plate 11, and then the knob 202 is pressed. When the knob 202 is pressed by force, it can move downward through the connection of the pressure plate 207 and push the spring 6 to compress. After the insertion rod 201 is completely moved downward, the positioning rod 206 moves When the slider 4 reaches the bottom position, the knob 202 is slightly rotated. When the knob 202 is rotated, the positioning rod 206 can be driven to rotate along the slot 5. After the positioning rod 206 rotates to the inner side of the slot 5, the position of the insertion rod 201 is clamped by the resilience of the spring 6. At this time, the movable plate 11 and the fixed plate 9 are in a fitted state, and the strings are clamped and fixed between the first tooth block 10 and the second tooth block 12. At this time, the pressing and rotating of the knob 202 realizes the quick clamping and fixing of the strings. After the strings are clamped and fixed, the user can adjust the position of the strings conveniently. After the position of the strings is adjusted, the strings can be wound to the outer side of the winding tube 205 to complete the fixing operation of the strings. The fixing operation of the strings is relatively convenient and quick.
[0024] Example 2, as Figures 1-4 As shown in , the upper end surface of the spring 6 is fixedly connected to a contact plate 7, a plurality of circular grooves are evenly opened on the top of the contact plate 7, balls 8 are arranged inside the circular grooves, and the top of the contact plate 7 fits with the bottom of the pressure plate 207.
[0025] The effect achieved by the entire embodiment 2 is that when the knob 202 is rotated after being pressed, the knob 202 drives the pressure plate 207 to press down and contact the ball 8 on the surface of the contact plate 7. When the pressure plate 207 rotates, the spring 6 is not subjected to the force of rotation through the connection of the ball 8, thereby avoiding the spring 6 from being twisted and damaged when the device is used, thereby improving the service life of the device.
[0026] Working principle: When replacing the strings of a guqin, make a dragonfly knot at one end of the string at the yueshan (the bridge at the head of the guqin), and then fixedly connect it with the velvet button. The head of the velvet button penetrates through the velvet button hole on the bottom plate of the guqin to the guqin surface and is flush with the yueshan. Then, insert the end of the string tail with a fly head into the velvet button and pull it to the position flush with the yueshan. Subsequently, closely wrap the string around the longyin (a part of the guqin) and wind and fix it at the peg 1. When sending the string to the position of the peg 1, it is necessary to tighten the string and align the spacing of the strings. During the operation, send the string to the position between the fixed plate 9 and the moving plate 11, and then press the knob 202. When the knob 202 is pressed, it can move downward through the connection of the pressure plate 207 and push the spring 6 to compress. After the insertion rod 201 completely moves downward, the positioning rod 206 moves to the bottom position of the chute 4. At this time, slightly rotate the knob 202. When the knob 202 rotates, it can drive the positioning rod 206 to rotate along the card slot 5. After the positioning rod 206 rotates to the inside of the card slot 5, use the resilience of the spring 6 to lock the position of the insertion rod 201. At this time, the moving plate 11 and the fixed plate 9 are in a fitting state, and the string will be clamped and fixed between the first tooth block 10 and the second tooth block 12. At this time, through the pressing and rotation of the knob 202, the quick clamping and fixing of the string are realized. After clamping and fixing the string, it is convenient for the user to adjust the position of the string. After adjusting the position of the string, wind the string around the outside of the winding tube 205 to complete the fixing operation of the string. The fixing operation of the string is relatively convenient and fast. When pressing and then rotating the knob 202, the knob 202 drives the pressure plate 207 to press down and contact the ball 8 on the surface of the contact plate 7. When the pressure plate 207 rotates, through the connection of the ball 8, the spring 6 will not be affected by the rotating force, avoiding the spring 6 being distorted and damaged during the use of the device, and improving the service life of the device.
[0027] The above is only a preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
