Description

Technical Field

[0001] The utility model relates to the technical field of konghou pull rod guides, in particular to a konghou pull rod guide seat. Background Art

[0002] The konghou is a very ancient plucked string instrument of the Han Chinese ethnic group. In ancient times, it was not only used in imperial court music but also widely among the people. It is often used in solos, duets, and as accompaniment for songs and dances, and is even used in large-scale folk orchestras. Modern konghous are often equipped with a pitch-shifting mechanism that allows the instrument to raise or lower its pitch, allowing it to produce a variety of tones and enhancing its expressiveness.

[0003] The pitch-changing mechanism generally changes the length of the playable strings by rotating the string-cutting structure, causing the pitch to fall or rise. The string-cutting structure generally has two ends. When both ends are attached to the strings, the section of the string will be compressed and unable to vibrate and produce sound. This section of the string is said to be cut off. The string-cutting structure is rotatably installed on the body of the instrument. The shaft is also connected to the connecting rod through other structures, and the connecting rod is controlled by a pull rod. The pull rod extends to the user's side, such as under the feet (the konghou and harp control the tuning mechanism through a foot-operated mechanism under the feet). The user controls the pull rod through the foot-operated mechanism to rotate the shaft. Generally, multiple pull rods are used to control the pitch of multiple groups of strings separately.

[0004] The drawbars are typically curved into a conical radial shape, located inside the instrument body and connected to the foot pedal. When in use, the curved portion of the drawbars is unstable, causing adjacent drawbars to collide and produce noise, affecting the playing effect. Furthermore, due to their lack of rigidity, when pushed upward, the drawbars have no fulcrum and are prone to bending. Utility Model Content

[0005] The purpose of the utility model is to provide a pull rod guide seat for a konghou, so as to solve the problems mentioned in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides a pull rod guide seat for a konghou, which is arranged inside the piano body and includes a vertical plate. The vertical plate is arranged horizontally and is detachably connected to the piano body. The vertical plate is provided with a plurality of limiting holes running through the vertical direction, and the plurality of limiting holes are respectively adapted to the plurality of pull rods in the piano body.

[0007] Furthermore, it also includes a bottom plate, which is arranged in the longitudinal direction and is detachably connected to the piano body, and the bottom plate is connected to the vertical plate.

[0008] Furthermore, the bottom plate and the vertical plate are connected by screws.

[0009] Furthermore, a mounting groove is provided on the bottom plate, and the mounting groove is adapted to one side of the vertical plate.

[0010] Furthermore, the nut end of the screw is cylindrical, and a receiving groove is formed on the bottom plate, and the receiving groove is adapted to the nut end of the screw.

[0011] Furthermore, the accommodating groove corresponds to the mounting groove.

[0012] The beneficial effects of the present invention are as follows: the guide seat of the present invention plays a guiding role for the pull rod by setting a vertical plate with multiple limiting holes. The pull rod will move along the limiting holes on the guide seat, and the movement path of the pull rod is restricted and guided to prevent collisions between adjacent pull rods.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiment described is only one embodiment of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to make the objectives, technical solutions and advantages of this application clearer, this application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In the following description, references to "one embodiment," "an embodiment," "an example," "an example," etc. indicate that the embodiment or example described may include certain features, structures, characteristics, properties, elements, or limitations, but not every embodiment or example necessarily includes the certain features, structures, characteristics, properties, elements, or limitations. In addition, repeated use of the phrase "according to one embodiment of the present application" may refer to the same embodiment, but does not necessarily refer to the same embodiment.

[0022] like Figure 1-Figure 4 As shown, the utility model discloses a guide seat 2 of a pull rod 3 of a konghou, which is arranged inside the piano body 1, and includes a vertical plate 21, which is arranged horizontally and detachably connected to the piano body 1, and has multiple limiting holes running through the vertical plate 21 in the longitudinal direction, and the multiple limiting holes are respectively adapted to the multiple pull rods 3 in the piano body 1.

[0023] When in use, multiple pull rods 3 pass through the corresponding limiting holes on the vertical plate 21 respectively, and the movement path of the pull rods 3 is restricted, ensuring the stability and accuracy of the pull rods 3 during movement. The limiting holes are set at a certain inclined arc, which is adapted to the bending direction of the pull rods 3. When the pull rods 3 are pulled down using the pedals, the pull rods 3 will move along the limiting holes on the guide seat 2. When the pull rods 3 are pushed upward, the pull rods 3 contact the inner wall of the limiting holes. Since the design of the limiting holes takes into account the bending direction of the pull rods 3, this contact will be smoother and more uniform. While the inner wall of the limiting hole provides a fulcrum for the pull rods 3 to move upward to prevent the pull rods 3 from bending and deforming, it also reduces the wear caused by friction and improves the overall durability.

[0024] The guide seat 2 of the present invention plays a guiding role for the pull rod 3 by providing a vertical plate 21 with multiple limiting holes. The pull rod 3 will move up and down along the limiting holes on the guide seat 2. The moving path of the pull rod 3 is restricted and guided to prevent collisions between adjacent pull rods 3 and prevent the pull rod 3 from bending and deforming when being pushed upward, thereby achieving precise control of the strings and improving stability during performance.

[0025] In one embodiment, the guide base 2 further includes a bottom plate 22, which is disposed longitudinally and detachably connected to the body 1. The bottom plate 22 is connected to the upright plate 21. Specifically, in this embodiment, a first side of the bottom plate 22 is in contact with the body 1, and a second side of the bottom plate 22 is in contact with the upright plate 21. The bottom plate 22 and the upright plate 21 can be fixedly or detachably connected. In other words, the guide base 2 can be integral or split, forming a T-shape overall.

[0026] This allows the guide base 2 to be easily installed or removed when needed, making it easier to repair, replace, or adjust. At the same time, the bottom plate 22 provides stable support for the vertical plate 21. The bottom plate 22 and the vertical plate 21 together form a stable support structure, ensuring that the vertical plate 21 will not shake or shift when subjected to the force of the pull rod 3.

[0027] In one embodiment, the bottom plate 22 and the vertical plate 21 are connected by screws 4. The screw connection 4 provides a secure and adjustable connection method, which can ensure a tight connection between the bottom plate 22 and the vertical plate 21. At the same time, the screw connection 4 is easy to disassemble and install, which is convenient for maintenance, replacement or adjustment when needed.

[0028] In one embodiment, a mounting groove 23 is formed on the bottom plate 22, and the mounting groove 23 is adapted to one side of the vertical plate 21. In this embodiment, the mounting groove 23 is located on the second side surface of the bottom plate 22. The mounting groove 23 extends horizontally through the bottom plate 22 and opens toward the vertical plate 21, that is, the vertical plate 21 can be inserted into the mounting groove 23.

[0029] When upright plate 21 is inserted into mounting groove 23 and secured, its position and orientation are precisely defined, facilitating connection between upright plate 21 and base plate 22. This also enhances the stability of the connection between upright plate 21 and base plate 22. Because a portion of upright plate 21 is embedded in mounting groove 23, this design resists external vibrations and shocks, maintaining the stability of guide base 2.

[0030] In one embodiment, the nut end of screw 4 is cylindrical, and a receiving slot 24 is defined on base plate 22, adapted to accommodate the nut end of screw 4. In this embodiment, there are two screws 4 and receiving slots 24, specifically two hexagon socket head screws 4, each securing one end of vertical plate 21. Receiving slots 24 are defined on a first side surface of base plate 22.

[0031] When the screw 4 is tightened, the nut is completely embedded in the receiving groove 24, ensuring that the nut does not protrude from the surface of the bottom plate 22, so that the first side surface of the bottom plate 22 can be completely fitted with the piano body 1, increasing the contact area between the guide seat 2 and the piano body 1, thereby reducing the loosening of the guide seat 2 due to vibration or impact, and improving the stability of the guide seat 2.

[0032] In one embodiment, the receiving slot 24 corresponds to the mounting slot 23, that is, the receiving slot 24 and the mounting slot 23 are connected by a circular hole. When the vertical plate 21 is placed in the mounting slot 23, the threaded end of the screw 4 passes through the circular hole and screws into the vertical plate 21 in the mounting slot 23 until the nut end of the screw 4 can be smoothly inserted into the receiving slot 24. This corresponding relationship makes the entire installation process smoother and more precise.

[0033] The installation process of this embodiment is as follows:

[0034] Insert the vertical plate 21 into the mounting groove 23, and use the screw 4 to fix the vertical plate 21 to the bottom plate 22. At this time, the nut end of the screw 4 is completely in the receiving groove 24, and then fix the base on the piano body 1, and respectively set the multiple pull rods 3 in the corresponding limiting holes on the vertical plate 21.

[0035] The guide seat 2 of the present invention plays a guiding role for the pull rod 3 by providing a vertical plate 21 with multiple limiting holes. The pull rod 3 will move along the limiting holes on the guide seat 2. The moving path of the pull rod 3 is restricted and guided to prevent collisions between adjacent pull rods and prevent the pull rod 3 from bending and deforming when being pushed upward, thereby achieving precise control of the strings and improving stability during performance.

[0036] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
