Description

Technical Field

[0001] The utility model relates to the technical field of konghou pedal rods, in particular to a konghou pedal rod protective cover. 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 was often used in solo performances, duets, and as accompaniment for song and dance, and was even used in large-scale folk orchestras. Modern konghous are generally equipped with a pitch-shifting mechanism that adjusts the pitch of the konghou, allowing it to produce a variety of tones and enhancing its expressiveness. The pitch-shifting mechanism's pitch-shifting transmission device is located at the bottom of the konghou and is operated by a foot-operated pedal, known as a pitch-shifting pedal.

[0003] A pitch-changing foot pedal typically consists of a base, a footrest, and a footbar. The base has a sliding slot corresponding to the footbar. The first end of the footbar is located in the base, and the second end of the footbar passes through the sliding slot and connects to the footrest located outside the base. The user can control the footrest to move up and down in the sliding slot of the base, thereby moving the footrest up and down to change the pitch of the konghou.

[0004] To reduce vibration and friction between the pedal bar and the base, a protective cover is usually installed on the pedal bar to solve this problem. If the cover becomes old, damaged, or cracked, it will require professional maintenance personnel to replace it on site or the entire machine will be shipped back to the manufacturer for replacement, causing inconvenience.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] like Figure 1-3As shown, the utility model discloses a protective cover for a konghou footrest rod 1, which is arranged on the footrest rod 1 and corresponds to a sliding groove on a base 2. The protective cover includes a guide sleeve 4, which is a non-metallic elastic body. The guide sleeve 4 is sleeved on the footrest rod 1 and is detachably connected to the footrest rod 1. In the prior art, the first end of the footrest rod 1 is arranged in the base 2, and the second end of the footrest rod 1 passes through the sliding groove on the base 2 and is detachably connected to the foot pedal 3 located outside the base 2.

[0021] Since the guide sleeve 4 is a non-metallic elastomer, that is, the guide sleeve 4 can be made of elastomer materials such as rubber and silicone, it can effectively absorb the impact force and vibration generated during the pedaling process, while reducing the noise and vibration generated during the pedaling process, providing the performer with a more comfortable and quiet playing environment.

[0022] The guide sleeve 4 is secured to the pedal bar 1 by its own elastic tension. This means the user simply removes the pedal 3, then stretches and removes the guide sleeve 4, or breaks (cuts or scratches) it with a blade, and peels it off the pedal bar 1. This allows the sleeve to be easily removed and replaced if damaged or requires replacement, eliminating the need to disassemble or repair the entire pedal mechanism, significantly reducing maintenance costs and time.

[0023] The utility model uses a guide sleeve 4 made of a non-metallic elastomer to achieve shock absorption and reduce the collision and wear between the pedal rod 1 and the sliding groove on the base 2. At the same time, the user can replace the sheath of the konghou pedal rod 1 by himself without the need for professional maintenance personnel to be present or the entire machine to be sent back to the manufacturer for replacement. The utility model has a simple structure, low cost, and is easy for users to operate.

[0024] In one embodiment, a wear-resistant part 5 is provided on the outer side of the guide sleeve 4. That is, the wear-resistant part 5 is detachably provided on the outer side of the guide sleeve 4. When the wear-resistant part 5 is aged and damaged, the user only needs to remove the guide sleeve 4 and replace it with a guide sleeve 4 with a new wear-resistant part 5, thereby extending the service life of the guide sleeve 4 and achieving a good shock absorption effect.

[0025] In one embodiment, the wear-resistant member 5 is made of cloth, which can form a relatively smooth transition layer between the pedal rod 1 and the base 2, thereby reducing the friction between the pedal rod 1 and the base 2 and having a shock-absorbing effect.

[0026] In one embodiment, the wear-resistant member 5 is a cloth strip that is wrapped around the outside of the guide sleeve 4 and bonded to the guide sleeve 4. The cloth strip is tightly attached to the outside of the guide sleeve 4 and bonded to the guide sleeve 4. This design not only ensures a secure connection between the wear-resistant member 5 and the guide sleeve 4, but also provides additional protection for the guide sleeve 4. The user can also adjust the number of wraps of the cloth strip based on actual needs, thereby controlling the thickness of the wear-resistant member 5.

[0027] In one embodiment, the wear-resistant part 5 is a cloth cover, which is arranged on the outside of the guide sleeve 4 and connected to the guide sleeve 4 by sewing or bonding, which is convenient for users to use and reduces the installation time of the wear-resistant part 5.

[0028] In one embodiment, a positioning member 6 is mounted on the pedal bar 1. Positioning member 6 is used to limit the position of the guide sleeve 4 on the pedal bar 1. To install the guide sleeve 4, the user simply slides the guide sleeve 4 onto the pedal bar 1 and then pushes the guide sleeve 4 until it contacts the positioning member 6. The positioning member 6 limits the position of the guide sleeve 4 so that it aligns with the sliding groove on the base 2. In this embodiment, positioning member 6 is a positioning pin.

[0029] The workflow of the present invention is as follows:

[0030] This embodiment adopts a solution of wrapping the guide sleeve 4 with a cloth strip. When the cloth strip is worn and damaged due to long-term use, the foot pedal 3 is removed and the guide sleeve 4 wrapped with the old cloth strip is destroyed, that is, the original cloth strip and the guide sleeve 4 are cut and scratched with a blade, and then the guide sleeve 4 is peeled off from the foot pedal 1. Then, a new guide sleeve 4 (with a new cloth strip wrapped on the surface) is put on the foot pedal 1 and pushed to the positioning member 6. Finally, the foot pedal is reinstalled.

[0031] The utility model uses a guide sleeve 4 made of a non-metallic elastomer to achieve shock absorption and reduce the collision and wear between the pedal rod 1 and the sliding groove on the base 2. At the same time, the user can replace the sheath of the konghou pedal rod 1 by himself without the need for professional maintenance personnel to be present or the entire machine to be sent back to the manufacturer for replacement. The utility model has a simple structure, low cost, and is easy for users to operate.

[0032] 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.
