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 structure. 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] In the patent application number CN201822271644.0, the patent name is a drawbar guide structure for a musical instrument tuner, which discloses a musical instrument including a body, a guide groove provided in the body, the guide groove including a linear guide groove and a radial guide groove, a linear guide groove body provided in the linear guide groove, a plurality of drawbar grooves along the extension direction provided on one side of the linear guide groove body, a tapered guide groove body provided in the radial guide groove, and a semi-conical shape. The above structure separates the drawbars one by one through the linear guide groove body, and there will be no collision between the drawbars. The drawbars are restricted and cannot collide with the groove wall, thus ensuring that noise is not generated during playing; after the drawbars pass through the drawbar grooves, they are guided and dispersed by the tapered guide groove body, so as to be connected to the pedals. The tapered guide groove body plays the role of tightening and dispersing the drawbars, avoiding the collision noise between the drawbars in the section where the drawbars are connected to the pedals.

[0004] However, the above structure requires slots to be cut into the guitar body in sequence according to the number of tie rods. Manufacturers need to frequently change molds or equipment during the production process to adapt to different production needs. This not only increases the complexity and time of production, but also may lead to reduced production efficiency. Utility Model Content

[0015] 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.

[0016] 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.

[0017] 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.

[0018] like Figure 1-Figure 2As shown, the present invention discloses a guide structure for a konghou with a pull rod 4, comprising a body 1, a guide slot 2 being provided in the body 1, a plurality of guide tubes 3 being installed in the guide slot 2, and a pull rod 4 being provided in each of the plurality of guide tubes 3. In this embodiment, the guide tubes are provided in the front uprights of the body 1, the body 1 is provided with a tuning mechanism at the upper end of the guide slot 2, and a pedal mechanism is provided at the lower end of the guide slot 2, and the tuning mechanism and the pedal mechanism are connected by a pull rod 4.

[0019] A guide groove 2 is defined in the body 1, and multiple guide tubes 3 are used to accommodate different numbers of tie rods 4. This eliminates the need for manufacturers to frequently change molds or equipment to accommodate the required number of tie rods 4 during the production process, greatly simplifying production management processes and reducing management costs. Guide tubes 3 are installed in the guide groove 2, and their number corresponds to the number of tie rods 4. The guide tubes 3 are hollow inside and are used to accommodate the tie rods 4. The function of the guide tubes 3 is to guide the tie rods 4, prevent vibration, and reduce friction noise.

[0020] The utility model provides a guide groove 2 and a plurality of guide tubes 3 installed in the guide groove 2 to match the number of pull rods 4. The guide rods 4 are guided so that the pull rods 4 remain stable during use and prevent vibration, thereby achieving precise adjustment of the string pitch. At the same time, the plurality of pull rods 4 are prevented from colliding and rubbing during use, thereby preventing abnormal sounds and noises from affecting the performance.

[0021] In one embodiment, the guide groove 2 is fixedly connected to the guide tube 3, that is, the outer wall of the guide tube 3 is tightly fitted with the inner wall of the guide groove 2, ensuring that the pull rod 4 can move stably in the guide tube 3 when adjusting the string tension, avoiding unnecessary displacement or shaking of the guide tube 3 when subjected to tension or thrust, thereby ensuring the accuracy and stability of the pitch adjustment.

[0022] In one embodiment, the guide groove 2 and the plurality of guide tubes 3 are connected by foam glue, that is, the guide tubes 3 and the guide groove 2 are bonded by foam glue, and the space between the tube grooves is also filled with foam glue.

[0023] Because the cured foam possesses a certain degree of hardness and adhesion, it securely secures guide tube 3 within guide groove 2, reducing loosening or displacement due to vibration or external forces. Furthermore, the foam fills the space between the tubes and grooves, forming a tight seal that effectively prevents the intrusion of moisture and other corrosive substances, thereby extending the service life of guide groove 2 and guide tube 3. It also effectively reduces the transmission of sound and vibration, improving the stability of the guide groove 2 and guide tube 3 system and ensuring accurate pitch and precise adjustment.

[0024] In one embodiment, the guide tube 3 is made of non-metallic material.

[0025] In one embodiment, the guide tube 3 is made of plastic. Plastic materials generally have good damping properties, meaning they can absorb and reduce vibrations. During konghou performance, this damping effect helps reduce the noise and hum generated by the guide tube 3 when the strings vibrate, improving the clarity and purity of the sound quality. Furthermore, plastic is relatively light, so the guide tube 3 does not increase the overall weight of the konghou.

[0026] The design ideas of this utility model are as follows:

[0027] The existing konghou guide structure has multiple guide grooves, which are improved into a large guide groove 2. Multiple guide tubes 3 are installed in the guide groove 2 to accommodate different numbers of tie rods 4. The guide tubes 3 guide the tie rods 4, prevent vibration, and reduce friction noise. The guide tubes 3 are installed in the guide groove 2 with foam glue, and the tube groove is also filled with foam glue. This not only simplifies installation and reduces cost, further reduces vibration, but also effectively prevents moisture and other corrosive substances from entering the tube groove, thereby extending the service life of the guide groove 2 and guide tubes 3.

[0028] That is, the foot pedal is connected to the pull rod 4 through a pull rod connector. Multiple pull rods 4 are sequentially passed through corresponding guide tubes 3 provided in the front column. After passing through the guide tubes 3, the pull rods 4 are connected to the pitch-changing mechanism through the headstock connector. The foot pedal applies force to the pull rod connector, causing the pull rod 4 to start moving. Under the guidance of the guide tube 3, the pull rod 4 transmits the force of the foot pedal to the headstock connector. The headstock connector drives the dial in the pitch-changing mechanism to rotate, which will change the effective length of the strings and thus change the pitch of the strings, achieving the purpose of pitch change.

[0029] The utility model provides a guide groove 2 and a plurality of guide tubes 3 installed in the guide groove 2 to match the number of pull rods 4. The guide rods 4 are guided so that the pull rods 4 remain stable during use and prevent vibration, thereby achieving precise adjustment of the string pitch. At the same time, the plurality of pull rods 4 are prevented from colliding and rubbing during use, thereby preventing abnormal sounds and noises from affecting the performance.

[0030] 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.
