Technical Field
[0001] This utility model belongs to the field of guzheng production technology, specifically a guzheng string-threading auxiliary device. Background Technology
[0002] As a traditional Chinese musical instrument, the guzheng is becoming increasingly popular. With its growing popularity, more and more people are learning to play it. Before playing the guzheng, the strings need to be passed through the bridges from the soundboard. The tension of the strings needs to be adjusted to ensure a better performance.
[0003] Because the string-threading hole is small and extends all the way to the bottom of the guzheng, stringing requires turning the guzheng over or the operator crouching down to the bottom of the guzheng to quickly complete the stringing, which is inconvenient. Therefore, string-threading auxiliary devices have emerged. Most common string-threading auxiliary devices are rod-shaped structures with grooves at the lower end to hold the string. However, the difference between the outer diameter of the string-threading rod and the inner diameter of the string-threading hole is difficult to control. If the difference is too large, the string will fall off when pulled upwards. If the difference is too small, the string-threading rod holding the string is difficult to pull out. Even if it is pulled out, the string is likely to fall off due to friction in the string-threading hole, which greatly reduces the success rate of string threading and thus limits the efficiency of string threading. Therefore, it is necessary to develop a string-threading auxiliary device for the guzheng to solve the shortcomings of the existing technology. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5 As shown, this utility model provides a guzheng string-threading auxiliary device, including a control component 1, a connecting rod 2 sleeved on the upper end of the inner cavity of the control component 1, a string-threading component 4 sleeved on the lower end of the inner cavity of the control component 1, the upper end of the connecting rod 2 extending to the top of the control component 1 and fixedly connected to a pressing block 3, and the string-threading component 4 and the connecting rod 2 being interconnected through the control component 1.
[0024] The string threading assembly 4 includes a limiting block 41 that is movably fitted inside the control assembly 1. The limiting block 41 moves up and down with the connecting rod 2 via the control assembly 1. The bottom of the limiting block 41 is fixedly connected to the string threading rod 42. The string threading rod 42 has a string threading hole 43 inside. A rubber pressure ring 44 located at the lower end of the string threading hole 43 is fixedly fitted onto the outer surface of the string threading rod 42. The difference between the outer diameter of the rubber pressure ring 44 and the inner diameter of the control assembly 1 is smaller than the diameter of the string. Due to the setting of the string threading assembly 4, the string threading assembly 4 can move up and down along the inside of the control assembly 1 with the cooperation of the connecting rod 2 and the pressing block 3. Then, with the cooperation of the second sliding surface 134, the string can be pulled into the inside of the control assembly 1 through the string threading hole 43 and clamped with the cooperation of the rubber pressure ring 44, thereby ensuring that the string will not fall off when it is lifted upward.
[0025] like Figure 2 As shown, the control component 1 includes an operating tube 11 sleeved outside the connecting rod 2, a flexible connection 12 connected to the bottom of the operating tube 11, and a limit component 13 connected to the lower end of the flexible connection 12.
[0026] like Figure 3 and Figure 4 As shown, the flexible connection 12 includes a first spring 121 fixedly connected to the bottom of the operating tube 11. A second spring 122 is sleeved inside the first spring 121. The upper end of the second spring 122 is fixedly connected to the bottom of the connecting rod 2, and the lower end of the second spring 122 is fixedly connected to the top of the limiting block 41. Due to the setting of the flexible connection 12, it can be ensured that the pressing block 3 and the connecting rod 2 can push the string-passing assembly 4 to move through the second spring 122. At the same time, it can also be ensured that the limiting assembly 13 and the string-passing assembly 4 as a whole can be bent relative to the operating tube 11, so that the string-passing assembly 4 can be bent into the operator's field of vision, so as to facilitate the string being passed into the string-passing hole 43.
[0027] like Figure 4 and Figure 5 As shown, the limiting component 13 includes a limiting tube 131 fixedly connected to the bottom of the first spring 121. A limiting cavity 132 is formed inside the limiting tube 131. A first sliding surface 133 is provided at the lower end of the outer surface of the limiting cavity 132, and a second sliding surface 134 is provided at the lower end of the inner cavity of the limiting cavity 132. The upper end of the second sliding surface 134 is smoothly connected to the inner wall of the limiting cavity 132. The difference between the inner diameter of the lower end of the second sliding surface 134 and the outer diameter of the rubber pressure ring 44 is greater than the diameter of the string. Due to the setting of the second sliding surface 134, under the drive of the string hole 43, it is convenient for the string threading component 4 to pull the string into the interior of the limiting cavity 132, while ensuring that the rubber pressure ring 44 can clamp the string with the cooperation of the limiting cavity 132.
[0028] like Figure 4 and Figure 5 As shown, a limiting ring 135 located on the top of the limiting block 41 is fixedly sleeved on the top of the inner cavity of the limiting tube 131, and the limiting ring 135 is sleeved on the outside of the second spring 122.
[0029] like Figure 4 and Figure 5As shown, the limiting tube 131 has a positioning groove 136 located at the bottom of the limiting ring 135 and outside the limiting cavity 132. The limiting block 41 is slidably sleeved inside the positioning groove 136. The positioning groove 136 is provided with a positioning spring 137 that abuts against the bottom of the limiting block 41. The lower end of the positioning spring 137 abuts against the bottom of the inner cavity of the positioning groove 136. Due to the setting of the positioning groove 136, the limiting block 41 can move up and down smoothly. Then, under the elastic recovery action of the positioning spring 137, the string threading assembly 4 can automatically reset and pull the string into the interior of the limiting assembly 13.
[0030] like Figure 4 As shown, the first spring 121 and the second spring 122 have the same elastic strength, and the elastic strength of the first spring 121 and the second spring 122 is greater than the elastic strength of the positioning spring 137. Since the elastic strength of the flexible connection 12 is greater than that of the positioning spring 137, it is ensured that when the pressing block 3 is pressed, the limiting block 41 can be pushed by the second spring 122 and the positioning spring 137 can be compressed.
[0031] Working principle and usage process of this utility model:
[0032] Insert the flexible connector 12 and the limiting component 13 into the string hole from top to bottom through the operating tube 11. After ensuring that the flexible connector 12 passes the lower end of the string hole, press the pressing block 3 to push the limiting block 41 through the connecting rod 2 and the second spring 122, so that the limiting block 41 moves down along the inside of the limiting cavity 132. As the limiting block 41 moves down, it compresses the positioning spring 137 under the restriction of the positioning groove 136. When the limiting block 41 pushes the string rod 42 down until the string hole 43 moves to the outside of the limiting tube 131, then pull the limiting component 13 to bend the limiting component 13 and the operating tube 11 together with the cooperation of the flexible connector 12 until the string hole 43 at the lower end of the limiting component 13 is bent into the visible range of the operator outside the projection surface of the guzheng.
[0033] Then, the string is inserted into the string hole 43. At this time, releasing the limiting component 13 and the pressing block 3 will allow the limiting component 13, the flexible connection 12, and the operating tube 11 to return to the same axis under the elastic recovery action of the flexible connection 12 and the positioning spring 137. At the same time, the string threading component 4 pulls the string through the string hole 43 to move into the interior of the limiting cavity 132. With the cooperation of the second sliding surface 134, the string is clamped between the limiting cavity 132 and the rubber pressure ring 44. Then, lifting the operating tube 11 will bring out the string clamped by the string threading component 4 through the flexible connection 12 and the limiting component 13. Finally, pressing the block 3 again will push the string from the interior of the limiting cavity 132.
