Description

Technical Field

[0001] This utility model relates to the field of dulcimer structure technology, specifically to a dulcimer structure that can prevent deformation. Background Technology

[0002] The dulcimer is made by striking the strings stretched on the body with hammers, causing the strings to vibrate and transmit the vibrations through the bridge to the soundbox, thus producing a rich variety of musical tones. To ensure the accuracy of the sound and the fullness of the tone, the dulcimer usually needs to be equipped with multiple sets of strings, and each set of strings needs to maintain a high tension to meet the requirements of pitch and vibration performance.

[0003] One of the most notable characteristics of the dulcimer is its large total tension of the strings. However, due to the large number of strings and the high tension requirement of each string, the frame of the instrument is prone to structural deformation under long-term high tension. Therefore, we propose a dulcimer structure that can prevent deformation and can directly reinforce the structure of the dulcimer, thereby reducing the deformation of the instrument.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1 to 4A deformation-resistant dulcimer structure includes a top support frame 1, a bottom support frame 2, reinforcing side plates 3, reinforcing teeth 4, and reinforcing components. The bottom support frame 2 is detachably installed on the underside of the top support frame 1. Two reinforcing side plates 3 are symmetrically and detachably installed between the top support frame 1 and the bottom support frame 2. Multiple reinforcing teeth 4 are fixedly connected to the two reinforcing side plates 3. The top support frame 1 and the bottom support frame 2 each have multiple reinforcing slots that match the reinforcing teeth 4, allowing for reinforcement of the top support frame 1 and the bottom support frame 2. The frame 2 and the two reinforced side plates 3 can be quickly spliced ​​together, and at the same time, the two reinforced side plates 3 can stably support the top support frame 1 and the bottom support frame 2. The reinforcement components are set in two sets, and the two sets of reinforcement components are respectively installed between the top support frame 1, the bottom support frame 2 and the two reinforced side plates 3. The support side plates 10 are installed between the top support frame 1 and the bottom support frame 2. The reinforced straight plate 8 and the reinforced inclined plate 9 are in contact with the support side plates 10. Through the top support frame 1, the bottom support frame 2, the support side plates 10 and the two reinforced side plates 3, a dulcimer reinforcement frame can be formed, so that the dulcimer can be directly reinforced and supported.

[0033] refer to Figures 1-4 The reinforcement components include trapezoidal reinforcement blocks 5, rhomboid reinforcement plates 6, and fixing nails 7. Two trapezoidal reinforcement blocks 5 are provided, each detachably connected to the top support frame 1 and the bottom support frame 2. Both the top support frame 1 and the bottom support frame 2 have trapezoidal reinforcement grooves matching the trapezoidal reinforcement blocks 5. Two rhomboid reinforcement plates 6 are provided, each detachably connected to the side reinforcement plate 3. The side reinforcement plate 3 has two rhomboid reinforcement grooves matching the rhomboid reinforcement plates 6. The trapezoidal reinforcement blocks 5 are bonded to the top support frame 1, and the rhomboid reinforcement plates 6 are bonded to the side reinforcement plate 3, facilitating the reinforcement of the trapezoidal... The trapezoidal reinforcing block 5 is stably installed in the reinforcing groove, and the rhomboid reinforcing plate 6 can be stably installed in the rhomboid reinforcing groove. Multiple fixing nails 7 are provided, and the multiple fixing nails 7 are detachably connected between the reinforcing side plate 3 and the two rhomboid reinforcing plates 6. The reinforcing side plate 3 has multiple fixing grooves that match the fixing nails 7, and the rhomboid reinforcing plate 6 has two fixing openings that match the fixing nails 7. The fixing openings are provided with sealant 11, which can smooth the fixing grooves and seal the fixing nails 7 to prevent the fixing nails 7 from rotating and loosening due to external factors, thereby improving the stability of the connection between the fixing nails 7 and the reinforcing side plate 3 and the rhomboid reinforcing plate 6.

[0034] After the two reinforced side plates 3 are symmetrically installed between the supporting top frame 1 and the supporting bottom frame 2, multiple trapezoidal reinforcing blocks 5 are placed in multiple trapezoidal reinforcing grooves, and multiple rhomboid reinforcing plates 6 are placed in multiple rhomboid reinforcing grooves, so that the multiple rhomboid reinforcing plates 6 abut against and support the multiple trapezoidal reinforcing blocks 5, increasing the stability of the trapezoidal reinforcing blocks 5 placed in the trapezoidal reinforcing grooves. Then, the trapezoidal reinforcing blocks 5 and rhomboid reinforcing plates 6 are bonded to the trapezoidal reinforcing grooves and rhomboid reinforcing grooves respectively with adhesive. Finally, multiple fixing nails 7 are used to connect the two reinforced side plates 3 and the multiple rhomboid reinforcing plates 6, which further increases the stability of the rhomboid reinforcing plates 6 installed on the reinforced side plates 3, and at the same time increases the stability of the trapezoidal reinforcing blocks 5 installed on the supporting top frame 1 and the supporting bottom frame 2.

[0035] refer to Figures 1-4 Multiple reinforcing straight plates 8 are detachably connected between the top support frame 1 and the bottom support frame 2. Multiple reinforcing straight grooves matching the reinforcing straight plates 8 are provided on both the top support frame 1 and the bottom support frame 2. The multiple reinforcing straight plates 8 are arranged in a linear array between the two reinforcing side plates 3. Two reinforcing inclined plates 9 are symmetrically and detachably connected to both sides of the multiple reinforcing straight plates 8. Reinforcing inclined grooves matching the reinforcing inclined plates 9 are provided on both the top support frame 1 and the bottom support frame 2.

[0036] Multiple reinforcing straight plates 8 are inserted into multiple reinforcing straight slots between the supporting top frame 1 and the supporting bottom frame 2, which can stably install the multiple reinforcing straight plates 8. At the same time, two reinforcing inclined plates 9 are stably inserted between the multiple reinforcing inclined slots, which can stably install the two reinforcing inclined plates 9. In addition, the two reinforcing inclined plates 9 and the multiple reinforcing straight plates 8 can smoothly splice and support the supporting top frame 1 and the supporting bottom frame 2, thereby improving the stability of the reinforcement.

[0037] In summary, the deformation-resistant dulcimer structure first requires the milling machine to be properly adjusted. Using molds, trapezoidal and rhomboid reinforcing grooves are milled into the support top frame 1, support bottom frame 2, and reinforcing side plates 3, respectively. After moving the support top frame 1 and support bottom frame 2 to suitable support and reinforcement positions, multiple reinforcing straight plates 8 are inserted between the multiple reinforcing straight grooves, and two reinforcing inclined plates 9 are inserted between the multiple reinforcing inclined grooves. Then, the two reinforcing side plates 3 are moved between the support top frame 1 and support bottom frame 2, and multiple reinforcing retaining teeth 4 are moved into the multiple reinforcing retaining grooves. This ensures that the deformation-resistant dulcimer structure can be achieved by milling traps and rhomboid reinforcing grooves into the support top frame 1 and support bottom frame 2. The two reinforcing side plates 3 are stably spliced ​​between the support frame 2. After the reinforcing side plates 3 are spliced, multiple trapezoidal reinforcing blocks 5 and multiple rhomboid reinforcing plates 6 are placed in multiple trapezoidal reinforcing grooves and multiple rhomboid reinforcing grooves respectively and glued. At the same time, multiple fixing nails 7 are connected to multiple rhomboid reinforcing plates 6 and two reinforcing side plates 3, which increases the stability of the trapezoidal reinforcing blocks 5 and rhomboid reinforcing plates 6 on the support top frame 1, support base frame 2 and reinforcing side plates 3, thereby forming a dulcimer reinforcing frame, which can reduce the structural deformation of the dulcimer frame under long-term high tensile force.

[0038] This anti-deformation dulcimer structure is achieved by adding composite wood blocks to fix the upper and lower backboards and the headstock together with wood screws and glue, which together resist the tension of the strings and are not easy to crack or deform under stress.
