Description

Technical Field

[0001] The utility model relates to a rosin clamp, in particular to a rosin clamp used for an erhu. Background Art

[0002] The erhu is a traditional folk instrument, beloved by the public. Many, especially retired seniors, learn it as a hobby. The erhu's sound is produced by the friction between the bow hair and the strings, requiring a certain level of friction. Therefore, every two to three hours of playing, or even less, the bow hair should be rubbed with rosin. This is typically done by laying the erhu down or at an angle, holding the bow in one hand and a rosin block in the other. Because the bow hair is sandwiched between the strings, applying rosin can be awkward, often resulting in broken bow hair, damaged strings, and the need for retuning. Furthermore, the bow hair tends to stick to the bow shaft, making it difficult to apply rosin, a particular challenge for beginners. Summary of the Invention

[0003] The utility model aims to solve the inconveniences caused by the need to smear rosin on the bow hair from time to time during the process of playing the erhu, and provides a rosin clip for the erhu.

[0004] The utility model provides a rosin clamp for an erhu, comprising a fixed clamp and a rosin clamp, wherein the clamping head of the fixed clamp is arranged on the neck of the erhu, and the bow hair of the erhu bow is placed in a gap between two rosin blocks in the clamping head at the upper end of the rosin clamp. During the pushing and pulling process of the bow hair, the rosin blocks in the clamping head at the upper end of the rosin clamp can rub rosin on the bow hair at any time. The fixed clamp and the rosin clamp are connected by a connecting rod, the lower end of the rosin clamp is vertically connected to the connecting rod, and the tail end of the fixed clamp is tiltedly connected to the connecting rod according to a set angle.

[0005] The fixing clip is a spring clip, and the clamp head of the fixing clip is round or oval. Felt pieces are attached to the two corresponding sides of the inner side of the clamp head of the fixing clip. The fixing clip can be fastened to the neck of the erhu through the clamp head. A spring is installed inside the fixing clip. The set angle between the fixing clip and the connecting rod is 40-60 degrees. The fixing clip is 55mm long. When the clamp head of the fixing clip is closed, the widest part of the inner opening is 11mm wide.

[0006] The rosin clip is a spring clip. A round hole is provided at the handle at the lower end of the rosin clip. A capped screw is passed through the round hole. The screw is 34 mm long. An internal thread knob is screwed to the other end of the screw. The opening and closing of the chuck at the upper end of the rosin clip is controlled by rotating the knob. The cross-section of the chuck at the upper end of the rosin clip is rectangular. Rectangular concave slots are provided on both sides of the inner side of the chuck. Rectangular rosin blocks are respectively embedded in the two slots. The angle between the two corresponding rosin blocks is 2 degrees when closed. The rosin clip is 73 mm long. The width of the surface connecting the rosin clip and the connecting rod is 24 mm. The concave slot in the chuck at the upper end of the rosin clip is 40-41 mm long and 20-21 mm wide. The thickness of the slot edge is 3 mm. The rosin block is 40 mm long, 20 mm wide and 11 mm thick.

[0007] The connecting rod is 15 mm long.

[0008] The operating principle of this utility model:

[0009] The rosin clamp for the erhu provided by the utility model is clamped onto the erhu's neck during use. The angle is adjusted so that the bow hair of the erhu bow is parallel to the plane of the rosin block. The knob at the lower end of the rosin clamp is rotated to form a predetermined gap between the two rosin blocks in the clamp head. The bow hair is preferably placed in the gap so that it is close to the tips of the rosin blocks on both sides and can be pulled. Rosin can be applied to the bow hair by pulling and pushing the bow in the same way as playing a violin. If the rosin block is severely worn and the two sides are not parallel or the gap is too large, the two sides of the bow hair can be rubbed against the two rosin blocks respectively, as in the case of playing the inner and outer strings. If the rosin block is skewed, it should be used upside down.

[0010] Beneficial effects of the utility model:

[0011] The rosin clamp for the erhu provided by this utility model has a simple structure, is easy to use, and is easy to master, making it particularly practical. It allows the user to easily apply rosin to the erhu bow hair while maintaining a normal erhu playing posture and method, achieving excellent results. This completely eliminates the hassle of applying rosin while playing the erhu, while also protecting the bow hair and strings from damage. BRIEF DESCRIPTION OF THE DRAWINGS
