Description

Technical Field

[0001] This utility model relates to the field of shock absorption structure technology, and in particular to a noise reduction and shock absorption plastic pad for a string pillow. Background Technology

[0002] Besides the guitar body, another crucial part of the guitar's tone is the nut. The guitar produces sound by the vibration of the strings, which in turn causes resonance. When the strings are plucked, the only medium that can affect the vibration of the strings is the nut.

[0003] In practical applications, traditional guitar nut pads present challenges in installation and positioning. During installation, they are prone to misalignment or jamming, resulting in inaccurate alignment between the pad and the nut shell. This necessitates repeated adjustments, increasing installation time and difficulty. Furthermore, installation requires specialized technical personnel. Over time or under external impact, the pad is prone to displacement, failing to securely fix itself within the nut shell. Consequently, it affects the tension of the guitar strings, leading to unstable sound quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of difficult installation and positioning and unstable fixation in the existing technology, and to provide a noise-reducing and vibration-damping plastic pad for a string pillow.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a noise-reducing and vibration-damping nut plastic pad, comprising a guitar body, a nut shell fixedly connected to the outer surface of the guitar body, a sliding groove formed on the inner wall of the nut shell, a nut piece slidably connected to the inner wall of the sliding groove, two first sliding ears fixedly connected to the outer surface of the nut piece, a stop block slidably connected to the inner wall of the sliding groove, two second sliding ears fixedly connected to the outer surface of the stop block, a connector fixedly connected to the outer surface of the nut shell, a fixing member rotatably connected to the inner wall of the connector, and a fixing groove formed on the inner wall of the fixing member.

[0006] In a preferred embodiment, a retaining ring is slidably connected to the inner wall of the fixing groove, a knob is rotatably connected to the inner wall of the retaining ring, and a fixing block is fixedly connected to the outer surface of the pillow piece.

[0007] In a preferred embodiment, the outer surface of the knob is threaded to the inner wall of the pillow shell.

[0008] In a preferred embodiment, the outer surface of the fixing block is engaged with the inner wall of the pillow shell.

[0009] In a preferred embodiment, the outer surface of the fastener is engaged with the outer surface of the stop block.

[0010] In a preferred embodiment, the outer surface of the retaining ring is slidably connected to the inner wall of the fixing member, and the outer surface of the fixing member is rotatably connected to the outer surface of the pillow shell.

[0011] In a preferred embodiment, the outer surface of the pillow piece is snapped onto the outer surface of the guitar body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention provides a clear sliding track for the pillow piece through the cooperation of the sliding groove and the first sliding lug. During installation, repeated adjustments are unnecessary, allowing for quick and precise alignment of the pillow piece and pillow shell, significantly reducing installation time. Laterally, a stop block restricts the pillow piece's sliding, while longitudinally, the first sliding lug and the fixing block engage and position it. Combined with the fixing component pressing against the stop block, a lateral and longitudinal fixing structure is formed, ensuring the pillow piece remains stable over a long period. The combination of the retaining ring and the knob continuously applies downward pressure to the fixing component after tightening, ensuring a tight fit between the fixing component and the stop block. This stably transmits the fastening force to the pillow piece, effectively resisting vibrations and external impacts during use, and guaranteeing long-term structural reliability.

[0019] 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. Example

[0020] like Figures 1-5 As shown, this utility model provides a technical solution: a noise-reducing and vibration-damping nut plastic pad, including a guitar body 1, a nut shell 2 fixedly connected to the outer surface of the guitar body 1, a groove 9 opened on the inner wall of the nut shell 2, a nut piece 3 slidably connected to the inner wall of the groove 9, the outer surface of the nut piece 3 engaging with the outer surface of the guitar body 1, two first sliding ears 10 fixedly connected to the outer surface of the nut piece 3, a stop block 4 slidably connected to the inner wall of the groove 9, two second sliding ears 12 fixedly connected to the outer surface of the stop block 4, a connector 8 fixedly connected to the outer surface of the nut shell 2, a fixing member 5 rotatably connected to the inner wall of the connector 8, the outer surface of the fixing member 5 engaging with the outer surface of the stop block 4, and a fixing groove 13 opened on the inner wall of the fixing member 5.

[0021] In this embodiment, the pillow shell 2 is designed with a sliding groove 9 on its inner wall. Rectangular grooves are also provided on both sides of the inner wall of the sliding groove 9 to facilitate the sliding connection of the pillow piece 3 to the inner wall of the pillow shell 2. First sliding ears 10 are fixed on both sides of the pillow piece 3, facilitating the vertical fixation of the pillow piece 3 and its sliding along the inner wall of the pillow shell 2. These ears also guide the pillow piece 3 to slide smoothly along the sliding groove 9, effectively preventing offset or jamming during installation. When the pillow piece 3 slides to the end of the pillow shell 2, the fixing block 11 fixed to the end of the pillow piece 3 engages precisely with the inner wall of the pillow shell 2. The fixing block 11 itself is a soft fixing block, which serves as a buffer during installation, reducing the impact of parts. The impact resistance protects the structural integrity of the pillow shell 2 and pillow piece 3. On the other hand, it allows the pillow piece 3 to be securely connected after connection. The other end of the pillow piece 3 is engaged with the stop block 4, so that the pillow piece 3 can be fixed to the inner wall of the slide groove 9 in the lateral direction. At this time, the pillow piece 3 is firmly connected to the pillow shell 2. The connector 8 is fixedly connected to the outer surface of the pillow shell 2, and the fixing member 5 is rotatably connected to the inner wall of the connector 8. The protruding part of the end of the fixing member 5 can press the stop block 4, thereby fixing the stop block 4. The stop block 4 firmly fixes the pillow piece 3 to the inner wall of the pillow shell 2. Even under long-term use or external impact, the reliability of the connection can be maintained, which greatly improves the durability and safety of the overall structure. Example

[0022] like Figures 1-5As shown, a retaining ring 7 is slidably connected to the inner wall of the fixing groove 13, the outer surface of the retaining ring 7 is slidably connected to the inner wall of the fixing member 5, the outer surface of the fixing member 5 is rotatably connected to the outer surface of the pillow shell 2, a knob 6 is rotatably connected to the inner wall of the retaining ring 7, the outer surface of the knob 6 is threadedly connected to the inner wall of the pillow shell 2, and a fixing block 11 is fixedly connected to the outer surface of the pillow piece 3, the outer surface of the fixing block 11 is engaged with the inner wall of the pillow shell 2.

[0023] In this embodiment, the fixing groove 13 opened on the inner wall of the fixing member 5 facilitates the knob 6 to pass through the inner wall of the fixing member 5 and be threadedly connected to the pillow shell 2. Because the fixing member 5 fixes the stop block 4 around the connector 8, the holes are not on the same plane due to angular offset when rotating. Therefore, a groove with a certain distance needs to be opened to avoid connection failure due to angular deviation. It can also perfectly adapt to the insertion requirements of the knob 6, so that the knob 6 can pass smoothly through the inner wall of the fixing member 5 and be threadedly connected to the pillow shell 2. The retaining ring 7 rotates and connects to the outer surface of the knob 6. On the one hand, the knob 6 can be screwed on smoothly. On the other hand, the knob 6 can continuously output downward pressure on the fixing member 5 when it is tightened. This allows the fixing member 5 to press the stop block 4 tightly, thereby firmly fixing the pillow piece 3 and transmitting the tightening force to the pillow piece 3. Finally, the pillow piece 3 is permanently and stably fixed on the inner wall of the pillow shell 2, effectively resisting vibration or external impact that may occur during use and ensuring the long-term reliability of the overall structure.

[0024] Working principle: like Figures 1-5 As shown, when the staff needs to install the pillow piece 3, firstly, the pillow piece 3 is inserted into the sliding groove 9 on the inner wall of the pillow shell 2 through the first sliding ears 10 on both sides. The rectangular grooves on both sides of the sliding groove 9 provide a guide track for the first sliding ears 10, ensuring that the pillow piece 3 is accurately positioned and slides smoothly in the vertical direction. When the pillow piece 3 is pushed to the end of the pillow shell 2, the fixing block 11 at its end will elastically engage with the corresponding slot on the inner wall of the pillow shell 2. The deformation characteristics of the soft material form a preliminary buffer fixation, which not only avoids hard collisions during installation, but also makes the pillow piece 3 initially fit with the pillow shell 2 through the elastic return force. The stop block 4 engages at the other end of the pillow piece 3. The stop block 4 is embedded in the slide groove 9, which restricts the displacement of the pillow piece 3 laterally and prevents it from sliding accidentally along the slide groove 9. At this time, the pillow piece 3 is basically fixed in both the longitudinal and transverse directions. During the tightening of the knob 6, the retaining ring 7 on its outer surface moves synchronously with the knob 6 but does not rotate with it. This reduces the frictional resistance when tightening and applies continuous downward pressure to the fixing member 5 through the retaining ring 7, so that the fixing member 5 tightly holds the stop block 4 and transmits the fastening force to the pillow piece 3. Finally, the pillow piece 3 is permanently and stably fixed in the inner wall of the pillow shell 2, effectively resisting the vibration or external impact that may occur during use and ensuring the long-term reliability of the overall structure.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
