Description

Technical Field

[0001] The utility model relates to the technical field of konghou pedals, in particular to a konghou pedal 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 solo performances, duets, and as accompaniment for songs and dances, and is even used in large national 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, located at the bottom of the konghou, uses a foot-operated pedal, known as a pitch-shifting foot. The current pitch-shifting foot pedal uses the vertical displacement of a long transmission rod to adjust the pitch-shifting mechanism's transmission output.

[0003] Existing pedal structures typically feature multiple pedal assemblies arranged in sequence within a base. The connection points between the pedal assemblies and the tuning rods are often irregularly arranged, straight in a line, or in an arc shape. Furthermore, the pedal rods of the pedal assemblies are often designed with a horizontally curved shape. However, curved pedal rods often concentrate stress at the bend. Prolonged use and the application of strong force can lead to stress concentration at the bend, resulting in excessive torque and an increased risk of breakage or damage. Utility Model Content

[0004] The purpose of the utility model is to provide a konghou pedal structure to solve the problem mentioned in the above background technology that the existing pedal may cause stress concentration at the bend of the pedal rod and excessive torque when used for a long time and with strong force, thereby increasing the risk of breakage or damage of the pedal rod.

[0008] Furthermore, the number of the pedal rods in the first group is one, and the middle part is concave upwards; the number of the pedal rods in the second group is three, and all are linear; the number of the pedal rods in the third group is three, and the middle parts are all concave downwards.

[0009] Furthermore, the second group of pedal assemblies and the third group of pedal assemblies are symmetrically arranged along the central axis of the first group of pedal rods.

[0011] Furthermore, a protective sleeve is installed on the second end of the pedal rod, and the protective sleeve is used to reduce the wear between the pedal rod and the inner wall of the sliding groove.

[0012] The beneficial effects of the present invention are as follows: by designing the pedal rods to have a linear horizontal projection, i.e., by designing the multiple pedal rods to be concave upward or downward, the present invention avoids bending in the horizontal direction.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] like Figure 1-Figure 3 As shown, the utility model discloses a konghou footrest structure, which includes a base 1, on which are provided a plurality of footrest assemblies 2. The footrest assemblies 2 include footrest rods 21, the horizontal projection of which is a straight line. That is, the footrest rods 21 are a straight line in the horizontal direction and have no bends. This design greatly reduces the risk of the footrest rods 21 bending due to excessive torque during pedaling. At the same time, since the horizontal projection of the footrest rods 21 is a straight line, the shape and size of each footrest rod 21 can be more standardized, avoiding complex bending processes, reducing design difficulty and manufacturing complexity. This facilitates mass production using mechanized or automated equipment, reducing processing time and cost. During installation, there is no need to consider complex bending angles and positioning issues, and the footrest rods can be directly fixed to the base 1, greatly simplifying the installation process and improving installation efficiency. It also makes the entire footrest structure more compact in the vertical space, thereby saving horizontal space.

[0022] The utility model designs the pedal rods 21 so that their horizontal projections are linear, i.e., the multiple pedal rods 21 are each designed to be concave upward or downward, thereby preventing bending in the horizontal direction. At the same time, the utility model fully utilizes the longitudinal three-dimensional space so that the multiple pedal rods 21 do not interfere with each other during use, thereby greatly reducing the risk of bending of the pedal rods 21 due to excessive torque during pedaling. Furthermore, the utility model facilitates the manufacture and installation of the pedal structure and saves horizontal space.

[0023] In one embodiment, the footrest assembly 2 is divided into three groups. The first group of footrest rods 21 is located above the second group of footrest rods 21, and the third group of footrest rods 21 is located below the second group of footrest rods 21. Specifically, the footrest assembly is arranged in three layers. The footrest rods 21 in different groups can be concave upward or downward in the longitudinal direction, fully utilizing the three-dimensional space of the upper, middle, and lower layers. This prevents interference between the multiple footrest rods 21 when the operator is using them. This occupies less space on the base 1, facilitating a more compact design within limited space and achieving high space utilization.

[0024] In one embodiment, the foot pedal assembly 2 also includes a pressure rod bolt 22 and a foot pedal 23. The pressure rod bolt 22 is arranged longitudinally, the first end of the pressure rod bolt 22 is bolted to the base 1, and the second end of the pressure rod bolt 22 is rotatably connected to the first end of the foot pedal 21. The foot pedal 23 is located on the outside of the base 1 and is connected to the second end of the foot pedal 21.

[0025] In one embodiment, the first set of footrest rods 21 comprises one footrest rod 21 with a concave center portion, the second set of footrest rods 21 comprises three footrest rods 21 with all being linear, and the third set of footrest rods 21 comprises three footrest rods 21 with all being concave center portions. In this embodiment, the central axis of the first set of footrest rods 21 coincides with the central axis of the base 1.

[0026] In one embodiment, the second set of footrest assemblies 2 and the third set of footrest assemblies 2 are symmetrically arranged along the central axis of the first set of footrest rods 21 to facilitate use by the operator.

[0027] In one embodiment, the base 1 includes a base upper plate 11, a base side plate 12 and a bottom plate 13. The base upper plate 11 is connected to the top of the base side plate 12. The base side plate 12 is provided with a stepped slide 14 corresponding to the foot pedal assembly 2. The second end of the foot pedal 21 is located in the slide 14. The bottom plate 13 is connected to the bottom surface of the base upper plate 11, and the bottom plate 13 is threadedly connected to the pressure rod bolt 22.

[0028] In one embodiment, a protective sleeve 3 is installed at the second end of the pedal rod 21 , and the protective sleeve 3 is used to reduce the wear between the pedal rod 21 and the inner wall of the slide groove 14 .

[0029] The design concept of the utility model is:

[0030] The pedal rods 21 in the pedal assembly 2 are designed to have a horizontal projection that is linear, resulting in a straight horizontal line with no bends. This design significantly reduces the risk of the pedal rods 21 bending due to excessive torque during pedaling. The pedal assembly 2 is divided into three groups, arranged in upper, middle, and lower layers. Each group of pedal rods 21 is cross-designed horizontally and arranged in parallel vertically. This means that different groups of pedal rods 21 can be concave upward or downward in the longitudinal direction, preventing interference between the multiple pedal rods 21 when used by the operator. The pedal rods 21 occupy less space in the base 1, facilitating a more compact design within the limited space and improving base 1 space utilization.

[0031] The utility model designs the pedal rods 21 so that their horizontal projections are linear, i.e., the multiple pedal rods 21 are each designed to be concave upward or downward, thereby preventing bending in the horizontal direction. At the same time, the utility model fully utilizes the longitudinal three-dimensional space so that the multiple pedal rods 21 do not interfere with each other during use, thereby greatly reducing the risk of bending of the pedal rods 21 due to excessive torque during pedaling. Furthermore, the utility model facilitates the manufacture and installation of the pedal structure and saves horizontal space.

[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.
