[0023] The following is for reference. Figures 1 to 4 This invention describes a musical instrument skinning device according to an embodiment of the present invention.

[0024] According to an embodiment of the present utility model, the instrument skinning device is referenced. Figure 1 As shown, it includes a base 100, a lifting plate 200, and a clamping plate 300.

[0025] The base 100 can be a circular plate structure, with a through hole in the center to reduce its weight and facilitate the dissipation of moisture from the snakeskin 800. Alternatively, the base 100 can have other structures, such as a square plate or legs, which will not be elaborated upon here.

[0026] The lifting plate 200 can be a circular plate structure, horizontally positioned above the base 100, meaning its surface along its thickness is horizontal. The lifting plate 200 can be adjusted up and down relative to the base 100. The lifting plate 200 has a first clearance hole 201, which can be located at the center of the lifting plate 200, meaning its centerline can coincide with the centerline of the lifting plate 200. The size of the first clearance hole 201 is slightly larger than the size of the soundbox 700.

[0027] The clamping plate 300 can be a circular plate structure. The clamping plate 300 is horizontally positioned above the lifting plate 200, that is, the surface of the clamping plate 300 in the thickness direction is horizontally positioned. The clamping plate 300 has a second clearance hole 301. The second clearance hole 301 can be located at the center of the clamping plate 300, that is, the center line of the second clearance hole 301 can coincide with the center line of the clamping plate 300. The size of the second clearance hole 301 is slightly larger than the size of the soundbox 700. The center line of the second clearance hole 301 coincides with the center line of the first clearance hole 201. The clamping plate 300 is used to cooperate with the lifting plate 200 to clamp the edge of the snakeskin 800.

[0028] In this application, taking the erhu as an example, when skinning is required, the snakeskin 800 is soaked until soft. Then, the edge of the snakeskin 800 is clamped between the clamping plate 300 and the lifting plate 200. Next, the soundbox 700 is placed in the center of the base 100 with the skinned end facing upwards. Then, the lifting plate 200 is lowered, allowing the soundbox 700 to pass through the first clearance hole 201 and the second clearance hole 301, pressing against the snakeskin 800 and putting it in a taut state, thus completing the skinning operation. The instrument skinning device according to this utility model embodiment is not only simple in structure and more convenient to operate, saving time and effort, but also does not damage the skin or the soundbox 700. Furthermore, it makes the snakeskin 800 more evenly stressed, resulting in better tension and higher skinning quality. In addition, it is applicable to snakeskin 800 of different thicknesses, making it more practical.

[0029] It should be noted that the instrument skinning device of this application can not only skin erhu, jinghu, huagu datong, quhu, yuehu, sihu and other huqin instruments, and process the instrument skinning device to a larger size, but can also skin some drum instruments, which will not be elaborated here.

[0030] refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the base 100 is provided with a plurality of vertically extending guide rods 400. The plurality of guide rods 400 are arranged circumferentially along the center line of the first clearance hole 201. The lifting plate 200 is provided with a corresponding sleeve hole 202 and is sleeved on the guide rods 400 through the sleeve hole 202. For example, there may be three, four or more guide rods 400, and the plurality of guide rods 400 may be evenly arranged circumferentially along the center line of the first clearance hole 201.

[0031] In this embodiment, the lifting plate 200 can be precisely raised and lowered vertically by the cooperation of multiple guide rods 400 and multiple sleeve holes 202. In addition, the lifting plate 200 can be balanced to prevent it from deflecting. As a result, the snake skin 800 is subjected to more uniform force and the skin is more uniform during the skinning process, resulting in a better skinning effect.

[0032] refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a spring 500 is sleeved on the outer side of the guide rod 400, and the two ends of the spring 500 abut against the top surface of the base 100 and the bottom surface of the lifting plate 200, respectively. The guide rod 400 is configured as a screw, and a locking nut 600 is threadedly connected to the guide rod 400. The locking nut 600 abuts against the top surface of the lifting plate 200.

[0033] In this application, the lifting plate 200 can be kept at the required height by the support of the spring 500 and the limiting of the locking nut 600. Moreover, when adjusting the height, it is only necessary to turn the locking nut 600 on the top of the lifting plate 200, which is simple and convenient to operate. In addition, after the skin is finished, the locking nut 600 is turned to the top of the guide rod 400, and the elastic restoring force of the spring 500 can make the lifting plate 200 automatically return to the initial state, which is more convenient to use and more practical.

[0034] It should be noted that the lifting plate 200 can also be raised and lowered in other ways, such as by controlling the lifting plate 200 with a cylinder, which will not be elaborated here.

[0035] refer to Figure 3As shown, in some embodiments of this utility model, a first elastic ring 203 is attached to the top surface of the lifting plate 200, and a second elastic ring 302 is attached to the bottom surface of the clamping plate 300. The first elastic ring 203 and the second elastic ring 302 are used to cooperate in clamping the edge of the snake skin 800.

[0036] For example, the first elastic ring 203 can be made of elastic rubber, tendon sheet, or other suitable materials. The first elastic ring 203 can be bonded to the top surface of the lifting plate 200. The first elastic ring 203 can be circular in shape, and its center line can coincide with the center line of the lifting plate 200. The second elastic ring 302 can be made of elastic rubber, tendon sheet, or other suitable materials. The second elastic ring 302 can be bonded to the bottom surface of the clamping plate 300. The second elastic ring 302 can be circular in shape, and its center line can coincide with the center line of the clamping plate 300.

[0037] In this embodiment, a first elastic ring 203 is attached to the top surface of the lifting plate 200, and a second elastic ring 302 is attached to the bottom surface of the clamping plate 300. Both the first elastic ring and the second elastic ring 302 can be elastically deformed. In this way, not only is the edge of the snake skin 800 clamped more securely, but damage to the snake skin 800 can also be reduced.

[0038] refer to Figure 3 As shown, in some embodiments of this utility model, anti-slip textures are formed on the top surface of the first elastic ring 203 and the bottom surface of the second elastic ring 302. In this embodiment, anti-slip textures are formed on the top surface of the first elastic ring 203 and the bottom surface of the second elastic ring 302. When the first elastic ring 203 and the second elastic ring 302 cooperate to clamp the edge of the snakeskin 800, the friction between them is greater, thus clamping the snakeskin 800 more firmly, making it easier to tension the snakeskin 800 and achieving a better tensioning effect.

[0039] refer to Figure 1 As shown, in some embodiments of this utility model, the wall of the first clearance hole 201 is flush with the wall of the second clearance hole 301. For example, when both the first clearance hole 201 and the second clearance hole 301 are set as round holes, the first clearance hole 201 and the second clearance hole 301 are coaxial and have the same diameter.

[0040] In this embodiment, this arrangement makes it easier for the soundbox 700 to pass through the first clearance hole 201 and the second clearance hole 301, avoiding the situation where the soundbox 700 gets stuck. In addition, it makes skinning easier and the skinning effect better.

[0041] refer to Figure 1 and Figure 3As shown, in some embodiments of this utility model, the inner peripheral wall of the first elastic ring 203 is flush with the hole wall of the first relief hole 201, and the inner peripheral wall of the second elastic ring 302 is flush with the hole wall of the second relief hole 301.

[0042] For example, when the first clearance hole 201 is a circular hole and the first elastic ring 203 is annular, the centerline of the first clearance hole 201 can coincide with the centerline of the first elastic ring 203, and the inner diameter of the first elastic ring 203 is equal to the diameter of the first clearance hole 201. When the second clearance hole 301 is a circular hole and the second elastic ring 302 is annular, the centerline of the second clearance hole 301 can coincide with the centerline of the second elastic ring 302, and the inner diameter of the second elastic ring 302 is equal to the diameter of the second clearance hole 301.

[0043] In this embodiment, this arrangement makes it easier for the soundbox 700 to pass through the first clearance hole 201, the second clearance hole 301, the first elastic ring 203, and the second elastic ring 302, avoiding the soundbox 700 from getting stuck. In addition, it makes skinning easier and the skinning effect better.

[0044] refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a plurality of fasteners 303 are provided between the clamping plate 300 and the lifting plate 200, and the plurality of fasteners 303 are evenly arranged circumferentially along the center line of the first clearance hole 201. In this application, by loosening the fasteners 303, extending the snake skin 800 between the clamping plate 300 and the lifting plate 200, and then tightening the fasteners 303, the snake skin 800 can be clamped, thereby enabling subsequent skinning. The operation is simple and convenient, saving time and effort, and can be applied to snake skin 800 of different thicknesses. In addition, the plurality of fasteners 303 are evenly arranged circumferentially along the center line of the first clearance hole 201, making the clamping of the snake skin 800 more uniform, the force on the snake skin 800 more uniform, and thus the tensioning effect of the snake skin 800 is better.

[0045] refer to Figure 4 As shown, in some embodiments of this utility model, the wall of the first clearance hole 201 is circular, and the wall of the second clearance hole 301 is circular. In this embodiment, the circular walls of the first clearance hole 201 and the circular walls of the second clearance hole 301 facilitate the skinning of some erhu, such as the gaohu, huagu datong, and jinghu, and also facilitate the skinning of general drum instruments.

[0046] refer to Figure 4As shown, in some embodiments of this utility model, the wall of the first clearance hole 201 is a regular polygon, and the wall of the second clearance hole 301 is a regular polygon. For example, the wall of the first clearance hole 201 can be a regular hexagon, and the wall of the second clearance hole 301 can be a regular hexagon, which facilitates the skinning of erhu, yuehu, etc. Furthermore, the wall of the first clearance hole 201 can be a regular octagon, and the wall of the second clearance hole 301 can be a regular octagon, which facilitates the skinning of quhu, sihu, etc.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
