Description

Technical Field

[0001] The utility model belongs to the technical field of guqin, and relates to a yueshan, a chenglu and a guqin with a matching structure using the yueshan and the chenglu. Background Art

[0002] The yueshan (Yueshan) is the horizontal wooden bar on the top of the qin (qin), a traditional Chinese musical instrument used to support the strings. The guqin has a yueshan (Yueshan), located above the headstock and the highest part of the instrument. A hardwood strip, called a "chenglu," is inlaid on the side of the qin, near the headstock. It has seven "string holes" for threading the strings. The tail of the instrument is inlaid with a hardwood "dragon gum" carved with shallow grooves for string support. The seven strings ascend from the chenglu section, pass through the yueshan (Yueshan) and dragon gum, and then extend to a pair of "goose feet" at the bottom of the instrument, symbolizing the seven stars.

[0003] In traditional guqin, the yueshan and chenglu are generally separate parts, glued together (flat-jointed) with glue. Affected by temperature and humidity, cracks are likely to appear between the yueshan and chenglu over time. This not only affects the appearance of the guqin, but also affects the timbre of the guqin due to the outward turning of the strings due to the position of the chenglu, making the sound quality scattered and difficult to concentrate. In severe cases, it will affect its use.

[0004] There are also guqins in which the yueshan and chenglu are integrated (made from the same piece of wood). Because the tops of both the yueshan and chenglu are arched, processing them is difficult due to the limitations of processing equipment, resulting in a very low yield. Furthermore, the yueshan of high-quality guqins is often made of red sandalwood, and using the same piece of wood for both is also wasteful.

[0005] Therefore, it is necessary to provide a matching structure of Yueshan and Chenglu that is not prone to cracks, and a guqin using the matching structure. Utility Model Content

[0006] In order to at least solve the problem in the above-mentioned prior art that cracks easily appear at the bonding points between the Yueshan and the Chenglu in traditional guqin due to the influence of temperature and humidity, the utility model provides the following technical solution: a Yueshan, a groove is provided on the side wall of the Yueshan, and the groove is used to cooperate with the convex and concave part of the Chenglu for connection.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention. The terms "connected", "connected", and "set" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components; they can be wired electrical connections, radio connections, or wireless communication signal connections. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0043] See also Figure 1-12 , the utility model provides the following technical solutions: a Yueshan, referring to Figure 2 、 Figure 6 and Figure 10 As shown, a groove 201 is provided on the side wall of the Yueshan 2. This embodiment does not limit the shape and number of the groove 201. As long as the Yueshan 2 can be connected with the Chenglu 1 through the groove 201, this connection method solves the problem that cracks are easily formed at the bonding point between the Yueshan 2 and the Chenglu 1 in the traditional guqin due to the influence of temperature and humidity.

[0044] As an example of the specific number of grooves 201 described above, in this embodiment, the sidewall of the yueshan 2 is provided with at least one groove 201 along the length thereof, which aligns with the curve of the upper surface of the guqin top 3. In other words, the groove 201 can be continuous or discontinuous. Preferably, the length of the groove 201 is less than or equal to the length of the yueshan 2. When the length of the groove 201 is less than the length of the yueshan 2, the number of grooves 201 can be one or more (multiple grooves 201 are spaced apart on the yueshan 2, and all of the grooves 201 are located on the same curve), which can be flexibly determined based on actual site needs. When the length of the groove 201 is equal to the length of the yueshan 2, the number of grooves 201 can be only one.

[0045] Reference Figure 2 As shown, the lower surface of the Yueshan 2 is concentrically arranged with the groove 201, that is, the lower surface of the Yueshan 2 and the groove 201 are concentric arc structures; and / or the upper surface of the Yueshan 2 is concentrically arranged with the groove 201, that is, the upper surface of the Yueshan 2 and the groove 201 are concentric arc structures; and / or the upper surface and lower surface of the Yueshan 2 have the same area, so that the curves of the Yueshan 2 and the upper surface of the panel 3 remain consistent.

[0046] As an example of a specific connection method between the mountain 2 and the panel 3, in this embodiment, refer to Figure 11 As shown, the Yueshan 2 and the panel 3 are connected by a connecting member 5 (such as a nail), and one end of the connecting member 5 passes through the Yueshan 2 and the panel 3 to connect the two together. The effect diagram after the Yueshan 2 and the panel 3 are connected is shown in FIG. Figure 12 shown; or with reference to Figure 6 As shown, the lower surface of Yueshan 2 is provided with a mortise and tenon hole, which is used to connect with the panel 3; or the lower surface of Yueshan 2 extends outward to form a tenon 202, which is used to connect with the panel 3. The effect diagram after Yueshan 2 and panel 3 are connected is shown in FIG. Figure 8 It should be noted that the number of the tenon 202, the mortise and the connector 5 can be flexibly set according to actual needs. Figure 3 and Figure 4 As shown, the mount 2 and the panel 3 are connected in a concave-convex manner, that is, the lower surface of the mount 2 is not processed in any way, and the lower end of the mount 2 is directly inserted into the installation groove of the panel 3.

[0047] Reference Figure 10 As shown, the lower surface of the shank 2 is a horizontal plane. For the shank 2 of this shape, it can be connected to the panel 3 through a connecting member 5 (such as a nail).

[0048] The utility model also provides the following technical solutions: a dew-receiving Figure 2 、 Figure 6 and Figure 10As shown, the shape of one end of the dew receiving 1 is consistent with the shape of the groove 201 of the Yueshan 2 mentioned above, so that one end of the dew receiving 1 can be installed in the groove 201 of the Yueshan 2. Preferably, the shape of the other end of the dew receiving 1 is consistent with the shape of the groove 201 of the Yueshan 2, and the lengths of the two ends of the dew receiving 1 are different. In other embodiments, the shape of the dew receiving 1 is consistent with the shape of the groove 201 of the Yueshan 2 mentioned above, and the width of the dew receiving 1 is greater than the depth of the groove 201, and only a part of the dew receiving 1 is located in the groove 201. It should be noted that the dew receiving 1 and the Yueshan 2 are processed separately, which reduces the processing difficulty, and the suitable processing wood for each can be selected as needed. In addition, when the dew receiving 1 is deformed due to the temperature and humidity in the piano workshop, a new dew receiving 1 can be replaced separately.

[0049] The present invention also provides the following technical solution: a guqin, comprising: a panel 3, a bottom plate 4, a yueshan 2 and a chenglu 1 (referring to the yueshan 2 and chenglu 1 mentioned above). Figure 4 、 Figure 8 and Figure 12 As shown, the panel 3 can be a whole plate or composed of two plates, which is not limited in this embodiment. The bottom plate 4 is connected to the bottom of the panel 3. Preferably, the bottom plate 4 and the panel 3 are detachably connected, such as by snap-fit connection, plug-in connection, etc. A groove 201 is provided on the side wall of the shank 2, and the groove 201 is used for concave-convex connection with the shank 1. The shank 1 is provided with seven vertical holes 101 for threading strings. During assembly, one end of the shank 1 is inserted into the groove 201 of the shank 2. At this time, the part of the shank 1 located outside the groove 201 of the shank 2 reveals the seven vertical holes 101. Then, the matching structure of the shank 1 and the shank 2 is detachably connected to the panel 3, such as mortise and tenon connection, connection through the connecting piece 5, and concave-convex connection. This embodiment does not limit the connection method of the matching structure of the shank 1 and the shank 2 and the panel 3. The guqin uses a mortise and tenon joint structure during its production process, which can increase external forces and vibration loads, offset certain material deformations and inherent stresses, and improve quality, durability, and service life. It is understood that the relative positions of the sash 1, the top plate 3, and the bottom plate 4 are all provided with vertical holes 101, which facilitate the threading of the strings (not shown in the figure). It should be noted that when the top plate 3 is composed of two plates, after the two top plates 3 clamp the shan 2 (which has already been installed with the sash 1), the three are connected together using a connector 5. It is understood that the two top plates 3 and the shan 2 are each provided with a horizontal hole 6 for installing the connector 5. Preferably, the horizontal hole 6 is offset from the vertical hole 101 so as not to affect the installation of the strings. In addition, a complete guqin also includes components such as the strings, dragon gums, and goose feet. These components can be manufactured using existing technologies, and this embodiment does not limit the specific structure of these components. Furthermore, this embodiment does not limit the multiple manufacturing processes involved in making the guqin.

[0050] As a preferred embodiment of the above, in this embodiment, the panel 3 is provided with a mounting groove that matches the matching structure of the dew 1 and the mountain 2. The number of mounting grooves is related to how many boards the panel 3 is composed of, that is, the number of mounting grooves can be one or two. When the number of mounting grooves is one, refer to Figure 11 As shown, the panel 3 is composed of two panels, one of which is called the forehead 301 (the top panel) and the other of which is called the tail 302 (the top panel). The mounting groove is provided on the forehead 301 and is used only for mounting the sash 1. During assembly, one end of the sash 1 is inserted into the groove 201 of the shank 2. The mating structure of the sash 1 and the shank 2 is brought into close contact with the tail 302. The forehead 301 is then brought into close contact with this mating structure. The shank 2 is now clamped between the two panels 3, and the portion of the sash 1 outside the groove 201 of the shank 2 fits neatly within the mounting groove of the head. The connecting member 5 (such as a nail) is then passed from the cavity of the tail 302 through the horizontal hole 6 of the tail 302, the horizontal hole 6 of the shank 2, and the horizontal hole 6 of the forehead 301, completing the assembly. When there are two mounting grooves, since the connection between the mountain 2 and the dew 1 is concave-convex, the mounting groove is stepped. For the convenience of description, the mounting groove portion for mounting the dew 1 is referred to as the first mounting groove 303, and the mounting groove portion for mounting the mountain 2 is referred to as the second mounting groove 304. The position distribution of the first mounting groove 303 and the second mounting groove 304 is shown in FIG. Figure 3 and Figure 7 As shown, the panel 3 is now a single piece. During assembly, one end of the dew retainer 1 is inserted into the groove 201 of the shank 2, and the mating structure of the dew retainer 1 and the shank 2 is installed on the panel 3 (such as a mortise and tenon connection or a concave-convex fitting connection, which will not be described here). At this time, the portion of the dew retainer 1 located outside the groove 201 of the shank 2 is exactly in the first mounting groove 303, and the shank 2 is in the second mounting groove 304, and the assembly is complete.

[0051] It is understood from common technical knowledge that the present invention may be implemented through other embodiments that do not depart from its spirit or essential features.
