Description

Technical Field

[0001] The utility model relates to the field of guzheng, in particular to a guzheng string winder which can prevent strings from slipping. Background Art

[0002] Guzheng is a stringed instrument whose strings are tightened by pegs, wherein the pegs are generally mounted on the instrument body via a threaded structure. After the strings are fixed on the pegs, the tightness of the strings can be adjusted by rotating the pegs.

[0003] However, the threaded connection structure is easy to loosen, and the strings are easy to loosen during long-term use. Therefore, the guzheng is generally equipped with a wrench so that the tightness of the strings can be adjusted at any time using the pegs. This undoubtedly brings certain troubles to the use of the guzheng. Based on this, the utility model provides a guzheng string winder that can prevent the strings from slipping, so as to prevent the strings from loosening during use. Utility Model Content

[0004] Based on this, the utility model provides a guzheng string winder that can prevent strings from slipping, comprising a mounting seat in the shape of a long strip, the mounting seat being arranged along the left-right direction, and a mounting cavity being provided in the mounting seat; a worm is rotatably provided in the mounting cavity, the worm is located on the left side of the mounting cavity and is vertically arranged, and the upper end of the worm extends upward from the mounting seat to form an adjustment portion; a mounting shaft is also rotatably provided in the mounting cavity, the mounting shaft is located on the right side of the worm and is arranged along the front-back direction, and a worm wheel matching the worm is fixedly provided on the mounting shaft; a connecting hole that passes through the mounting shaft is also provided on the mounting shaft, and a window is provided at the top end of the mounting seat corresponding to the connecting hole, and the window is located directly above the connecting hole.

[0005] In the utility model, the string winder is installed on the guzheng and used to tighten the strings of the guzheng and adjust the tightness of the strings. The window provided on the top of the mounting seat is used for the strings to pass through so that the strings can enter the mounting cavity, and the connecting hole provided on the mounting shaft is used for the strings to pass through so that the strings can be wound and fixed on the mounting shaft, thereby realizing the installation of the strings on the string winder.

[0006] In the utility model, after the strings are fixed on the installation shaft, the worm gear can be driven to rotate by rotating the worm through the adjustment part, thereby driving the installation shaft to rotate. By rotating the installation shaft in different directions, the strings can be continued to be wound onto the installation shaft to tighten the strings, or the winding of the strings on the installation shaft can be reduced to loosen the strings. Among them, due to the self-locking characteristics of the worm gear structure, after the adjustment of the tightness of the strings is completed, the strings can be effectively prevented from driving the worm gear to rotate during use. Compared with the pegs that use a threaded structure to tighten the strings, the utility model can prevent the strings from loosening during the use of the guzheng, and there is no need to frequently adjust the tightness of the strings during use, which can effectively increase the convenience of using the guzheng.

[0007] In addition, in the utility model, the mounting seat is arranged in a long strip shape, and the worm and the worm wheel are also arranged along the length direction of the mounting seat. Therefore, the design width of the string winder can be made as narrow as possible to facilitate the close arrangement of the string winder on the guzheng, so as to ensure that the string winder installed on the guzheng can correspond one by one to the closely arranged strings of the guzheng.

[0008] Furthermore, the mounting seat is provided with at least two first mounting holes penetrating the mounting seat, and the first mounting holes are located outside the mounting cavity and are arranged around the mounting cavity.

[0009] In the utility model, the first mounting hole provided on the mounting seat is used for mounting the mounting seat on the guzheng, and the mounting seat can be fixedly mounted on the guzheng by using a bolt mounting structure.

[0010] Furthermore, the mounting seat is composed of an upper shell and a lower shell which are arranged up and down, and the first mounting hole is arranged through both the upper shell and the lower shell.

[0011] In the utility model, the mounting seat is composed of an upper shell and a lower shell arranged above and below, so the mounting cavity of the mounting seat can be opened by separating the upper shell and the lower shell, which can facilitate the installation of the worm and the mounting shaft inside, that is, the production of the string winder can be facilitated. The worm and the mounting shaft can be rotatably mounted in the mounting cavity through a bearing structure, and can also be rotatably mounted in the mounting cavity through a sliding matching structure with a mounting hole opened on the side wall of the mounting cavity.

[0012] In addition, the first mounting hole is set through the upper shell and the lower shell at the same time. Therefore, when the mounting seat is mounted on the guzheng through the first mounting hole using the bolt structure, by making the bottom of the mounting seat close to the guzheng, the bolt structure can further press and fix the upper shell on the lower shell. It can be seen that the bolt structure of the mounting seat can achieve the installation effect while effectively enhancing the stability and firmness of the overall structure of the mounting seat. Among them, the upper shell and the lower shell can be connected to each other by an adhesive structure, a snap-fit ​​structure, etc.

[0013] Furthermore, the left and right sides of the top of the upper shell extend leftward and rightward respectively to form a first mounting plate and a second mounting plate, and the first mounting plate and the second mounting plate are both provided with a second mounting hole vertically passing through them.

[0014] In the utility model, the first mounting plate and the second mounting plate are used as the mounting structure of the mounting seat, and can be fixed on the guzheng using a bolt structure through the second mounting holes thereon, thereby further strengthening the firmness of the connection structure between the mounting seat and the guzheng.

[0015] Among them, in view of the existence of the first mounting plate and the second mounting plate on the upper shell, when processing the mounting structure of the string winder on the guzheng, it is necessary to correspondingly process the groove-shaped mounting structure, so that the first mounting plate and the second mounting plate can fit the guzheng by embedding the lower end of the mounting seat into the groove-shaped mounting structure, thereby ensuring that the first mounting plate and the second mounting plate can be fixed to the guzheng through the bolt structure.

[0016] Furthermore, a reinforcing plate is also provided on the upper surface of the upper shell, which covers the window and the adjustment part, and the reinforcing plate is provided with a first opening corresponding to the window and connected to the window, and the reinforcing plate is provided with a second opening corresponding to the adjustment part for exposing the adjustment part.

[0017] In the present invention, the reinforcing plate fixedly arranged on the upper surface of the upper shell is used to strengthen the structural strength of the upper shell portion, so as to prevent the window provided at the upper shell portion and the through hole for the adjustment portion to pass through from affecting the structural strength of the upper shell portion, thereby effectively preventing the upper shell portion from deforming during use. Preferably, the reinforcing plate is integrally formed with the upper shell portion.

[0018] Furthermore, the adjusting portion is cylindrical, and two notches are formed at the top of the adjusting portion; the two notches are symmetrically arranged about the axis of the adjusting portion.

[0019] In the utility model, two notches arranged at the top of the adjusting part are used to facilitate the use of corresponding tools to operate the adjusting part, so as to conveniently rotate the worm through the adjusting part.

[0020] The principle and effect of the utility model are further explained below in combination with the above technical scheme and the accompanying drawings:

[0021] In the utility model, the string winder tightens the strings of the guzheng through a worm gear structure. It utilizes the self-locking characteristics of the worm gear structure and can effectively prevent the strings from driving the worm gear to rotate during use after the tightness of the strings is adjusted. Compared with the pegs that use a threaded structure to tighten the strings, the utility model can prevent the strings from loosening during the use of the guzheng, and there is no need to frequently adjust the tightness of the strings during use, which can effectively increase the convenience of using the guzheng.

[0028] In order to facilitate understanding by those skilled in the art, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments, wherein the directional terms such as front, back, left, right, etc. mentioned in the specification are all indicated by the attached Figure 1 Whichever:

[0029] like Figure 1-4A guzheng string winder that can prevent strings from slipping comprises a mounting seat in the shape of an elongated strip, the mounting seat being arranged along the left-right direction, and a mounting cavity 13 being provided in the mounting seat; a worm 2 is rotatably provided in the mounting cavity 13, the worm 2 is located on the left side of the mounting cavity 13 and is vertically arranged, and the upper end of the worm 2 extends upward from the mounting seat to form an adjusting portion 21; a mounting shaft 3 is also rotatably provided in the mounting cavity 13, the mounting shaft 3 is located on the right side of the worm 2 and is arranged along the front-back direction, and a worm wheel 4 that matches the worm 2 is fixedly provided on the mounting shaft 3; a connecting hole 31 that passes through the mounting shaft 3 is also provided on the mounting shaft 3, and a window is provided at the top end of the mounting seat corresponding to the connecting hole 31, and the window is located directly above the connecting hole 31.

[0030] In the utility model, the string winder is installed on the guzheng and used to tighten the strings of the guzheng and adjust the tightness of the strings. The window provided on the top of the mounting seat is used for the strings to pass through so that the strings can enter the mounting cavity 13, and the connecting hole 31 provided on the mounting shaft 3 is used for the strings to pass through so that the strings can be wound and fixed on the mounting shaft 3, thereby realizing the installation of the strings on the string winder.

[0031] In the present invention, after the strings are fixed on the mounting shaft 3, the worm gear 4 can be driven to rotate by rotating the worm 2 through the adjusting portion 21, thereby driving the mounting shaft 3 to rotate. By rotating the mounting shaft 3 in different directions, the strings can continue to be wound onto the mounting shaft 3 to tighten the strings, or the winding of the strings on the mounting shaft 3 can be reduced to loosen the strings. Among them, due to the self-locking characteristics of the worm gear structure, after the adjustment of the tightness of the strings is completed, the strings can be effectively prevented from driving the worm gear 4 to rotate during use. Compared with the pegs that use a threaded structure to tighten the strings, the present invention can prevent the strings from loosening during the use of the guzheng, and there is no need to frequently adjust the tightness of the strings during use, which can effectively increase the convenience of using the guzheng.

[0032] In addition, in the utility model, the mounting seat is arranged in a long strip shape, and the worm 2 and the worm wheel 4 are also arranged along the length direction of the mounting seat. Therefore, the design width of the string winder can be as narrow as possible to facilitate the close arrangement of the string winder on the guzheng, so as to ensure that the string winder installed on the guzheng can correspond one by one to the closely arranged strings of the guzheng.

[0033] In one embodiment, at least two first mounting holes 14 penetrating the mounting seat are formed on the mounting seat, and the first mounting holes 14 are located outside the mounting cavity 13 and surround the mounting cavity 13 .

[0034] In this embodiment, the first mounting hole 14 provided on the mounting base is used for mounting the mounting base on the guzheng. The mounting base can be fixedly mounted on the guzheng by using a bolt mounting structure.

[0035] In one embodiment, the mounting base is composed of an upper shell 12 and a lower shell 11 which are arranged one above the other, and the first mounting hole 14 is arranged to penetrate both the upper shell 12 and the lower shell 11 .

[0036] In this embodiment, the mounting seat is composed of an upper shell 12 and a lower shell 11 arranged one above the other. Therefore, the mounting cavity 13 of the mounting seat can be opened by separating the upper shell 12 and the lower shell 11, which can facilitate the installation of the worm 2 and the mounting shaft 3 inside, that is, the production of the string winder can be facilitated. The worm 2 and the mounting shaft 3 can be rotatably mounted in the mounting cavity 13 through a bearing structure, and can also be rotatably mounted in the mounting cavity 13 through a sliding matching structure with a mounting hole opened on the side wall of the mounting cavity 13.

[0037] In addition, the first mounting hole 14 is set through the upper shell 12 and the lower shell 11 at the same time. Therefore, when the mounting seat is mounted on the guzheng through the first mounting hole 14 using the bolt structure, by making the bottom of the mounting seat close to the guzheng, the bolt structure can further press and fix the upper shell 12 on the lower shell 11. It can be seen that the bolt structure of the mounting seat can achieve the installation effect while effectively enhancing the stability and firmness of the overall structure of the mounting seat. Among them, the upper shell 12 and the lower shell 11 can be connected to each other by an adhesive structure, a snap-fit ​​structure, etc.

[0038] In one embodiment, the left and right sides of the top of the upper shell 12 extend to the left and right respectively to form a first mounting plate 121 and a second mounting plate 122 , and the first mounting plate 121 and the second mounting plate 122 are both provided with a second mounting hole 123 vertically passing through them.

[0039] In this embodiment, the first mounting plate 121 and the second mounting plate 122 are used as the mounting structure of the mounting seat. Through the second mounting hole 123 thereon, they can be fixed to the guzheng using a bolt structure, thereby further strengthening the firmness of the connection structure between the mounting seat and the guzheng.

[0040] Among them, in view of the existence of the first mounting plate 121 and the second mounting plate 122 on the upper shell 12, when processing the mounting structure of the string winder on the guzheng, it is necessary to correspondingly process the groove-shaped mounting structure, so that the first mounting plate 121 and the second mounting plate 122 can fit the guzheng by embedding the lower end of the mounting seat into the groove-shaped mounting structure, thereby ensuring that the first mounting plate 121 and the second mounting plate 122 can be fixed to the guzheng through the bolt structure.

[0041] In one embodiment, a reinforcing plate 124 is further provided on the upper surface of the upper shell 12, and the reinforcing plate 124 covers the window and the adjusting portion 21, and the reinforcing plate 124 has a first opening corresponding to the window and connected to the window, and the reinforcing plate 124 has a second opening corresponding to the adjusting portion 21 for exposing the adjusting portion 21.

[0042] In this embodiment, the reinforcing plate 124 fixedly disposed on the upper surface of the upper shell 12 is used to strengthen the structural strength of the portion of the upper shell 12, so as to prevent the window provided at the portion of the upper shell 12 and the through hole through which the adjustment portion 21 passes from affecting the structural strength of the upper shell 12, thereby effectively preventing the upper shell 12 from deforming during use. Preferably, the reinforcing plate 124 is integrally formed with the upper shell 12.

[0043] In one embodiment, the adjusting portion 21 is cylindrical, and two notches 211 are formed at the top of the adjusting portion 21 ; the two notches 211 are symmetrically arranged about the axis of the adjusting portion 21 .

[0044] In this embodiment, the two notches 211 formed at the top of the adjusting portion 21 are used to facilitate the use of corresponding tools to operate the adjusting portion 21 , so as to conveniently rotate the worm 2 through the adjusting portion 21 .

[0045] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
