[0060] Embodiment 1

[0061] The gravity self-locking guitar stand 100 comprises a base 10, a connector 20 and a self-locking hanger 30. The base 10 is connected to the self-locking hanger 30 through the connector 20, forming a stable and convenient structure.

[0062] The self-locking hanger 30 is composed of a shell 31, which contains a drive assembly 40 and a lock block 50. Specifically, the self-locking hanger 30 is composed of a base 32 and two support arms 33 extending from the base 32, and the lock block 50 is located at the front end of the support arms 33. The base 32 and the support arms 33 together form a U-shaped groove r, which is specially designed to fix the neck of the guitar. This design ensures the safety of the guitar and facilitates operation.

[0063] The transmission assembly 40 includes a transmission member 41 vertically moving in the thickness direction of the shell and two transmission shafts 42, the transmission member 41 includes a block d1, vertical racks d2 arranged on both sides of the block d1, and a rear connecting portion d3 arranged at the rear side of the block d1, the transmission shafts 42 are provided with gears d4 matched with the vertical racks d2; the front end of the transmission shaft 42 extends out of the support arm 33 and is connected with the lock block 50; the first spring f is arranged between the transmission member 41 and the inner side of the top wall of the shell 31. As shown in Figure 7 and Figure 8 The first spring f is used to automatically reset the transmission member 41.

[0064] The transmission mode between the transmission member 41 and the transmission shaft 42 can also be an eccentric mechanism for transmission; the linear motion of the transmission mechanism is converted into the rotation of the transmission shaft.

[0065] The connector 20 includes a first connecting portion 21 connected with the base 10, a second connecting portion 22 connected with the self-locking hanger 30, and a third connecting portion 23 connected with the transmission member 41, the first connecting portion 21, the second connecting portion 22, and the third connecting portion 23 are in a straight line.

[0066] The rear end of the self-locking hanger 30 is connected with the second connecting portion 22, and the rear connecting portion d3 of the transmission member 41 is rotationally connected with the third connecting portion 23 of the connector 20.

[0067] As shown in Figure 7 When the guitar is not placed in the self-locking hanger 30, the first spring f drives the bottom of the transmission member 41 to fall on the bottom wall k2 of the shell 31, at this time, the self-locking hanger 30 is in an inclined upward posture, and the lock block 50 is in an open state.

[0068] As shown in Figure 8 When the guitar is placed in the U-shaped slot r of the self-locking hanger 30, the self-locking hanger 30 is rotated by a certain angle a relative to the second connecting portion 22 of the connector 20 under the action of the gravity of the guitar, the first spring f is compressed, the above-mentioned transmission member 41 moves upward in the thickness direction of the shell 31 until it is limited by the top wall k1 of the shell 31, the transmission shaft 42 rotates under the action of the movement of the transmission member 41, and the lock block 50 is in a closed state.

[0069] The technical effects of the technical means include: the gravity self-locking guitar stand 100 ingeniously utilizes the mechanical principle, realizes the rapid locking and releasing of the guitar through the automatic response mechanism of the self-locking hanger 30. When the guitar is not placed in the hanger, the first spring f keeps the transmission member 41 at the bottom position, and the lock block 50 keeps the open state, which is convenient for placing the guitar. It is ensured that the hanger can maintain in a ready-to-use state even without external operation.

[0070] Once the guitar is placed in the U-shaped slot r, the self-locking hanger 30 will sense the gravity of the guitar and activate the locking mechanism by rotating an angle a. In this process, the first spring f is compressed, the transmission member 41 moves upward, and the rotation of the transmission shaft 42 drives the lock block 50 to close, thereby locking the guitar. This automatic locking function not only improves the safety of the guitar stand, but also ensures the stable placement of the guitar, preventing accidental sliding.

[0071] Overall, the gravity self-locking guitar stand 100 provides a solution that automatically adapts to the placement and removal of the guitar without additional operation through the ingenious mechanical structure, including the coordinated work of the transmission member 41, the transmission shaft 42 and the first spring f. This technical means not only improves the user experience, but also prolongs the service life of the product by reducing the dependence on external force, while maintaining the simplicity of operation and stability of the hanger.

[0072] Preferably, the base 32 is provided with a guide groove h in the thickness direction in the inner cavity of the shell 31, and the transmission member 41 can move in the guide groove h; the guide groove h is surrounded by a plurality of guide walls h1. The guide groove h and the guide wall h1 provide a precise movement path for the transmission member 41, ensuring more stable and accurate movement in the vertical direction. This precise guiding reduces movement deviation caused by friction or inclination, thereby improving the response speed and reliability of the entire self-locking system.

[0073] In addition, the third connecting part 33 of the connector 30 includes two separate support arms c1, the rear connecting part of the transmission member 41 is inserted into the clamping groove c2 between the two support arms c1 and connected by the shaft pin c3; by using separate support arms c1 and clamping grooves c2 on the third connecting part 33 of the connector 30, and connecting by the shaft pin c3, the installation and adjustment of the transmission member 41 become simple and fast. The shaft hole on the rear connecting part d3 of the transmission member 41 is a waist-shaped hole p, which can fine-tune the angle and position between the transmission member 41 and the shell 31.

[0074] By using the waist-shaped hole p, the structural design between the transmission member 41 and the connector 30 can be simplified, because this design allows the transmission member 41 to move along the thickness direction of the inner cavity without relying on complex guide mechanisms. This avoids the situation where the transmission member 41 is hard to move and causes wear and jam in traditional structures. Thus, it ensures that the lock block 50 can respond quickly and accurately, achieving fast locking and releasing, and optimizing the user's experience.

[0075] The top wall of the shell 31 is provided with a resting rack v for resting the transmission shaft 42, and the transmission shaft 42 is provided with an axial limiting structure v1 to limit the axial movement of the transmission shaft 42. The resting rack v provides a stable support point for the transmission shaft 42, ensuring that the transmission shaft maintains the correct position in the vertical direction, and the axial limiting structure v1 ensures that the locking block 50 can be accurately locked and released during the placement or removal of the guitar, improving the safety of the entire self-locking system.

[0076] The design of the base 10, consisting of a cylindrical part 11 closed at the upper end and open at the lower end and a side seat 12, provides a solid and stable support foundation for the gravity self-locking guitar stand 100. The solid structure of the cylindrical part 11 not only enhances the overall load-bearing capacity, but also helps to disperse and reduce vibrations, ensuring the stability and durability of the guitar stand during use. The design of the side seat 12 cleverly provides an axis point for the first connecting part 31 of the connector 30, making the assembly and maintenance process simple and fast. In addition, the application of the knob assembly 60 provides a reliable fixing solution for users, ensuring that the connection between the connector and the base remains firm under various use conditions, thereby enhancing the safety and reliability of the entire guitar stand.

[0077] The above technical means make the guitar stand 100 compact and aesthetically pleasing in structure, while optimizing the mechanical distribution and reducing local stress concentration, thereby prolonging the service life of the product. The easy adjustability of the knob assembly 60 also allows users to fine-tune according to different use scenarios to achieve the best user experience.

[0078] The self-locking hanger 30 has two states: use and storage, which facilitates quick switching according to needs. In the storage state, the hanger 30 can be neatly hung below the side seat 12 through the connector 30, saving space and maintaining the neat appearance of the guitar stand. This technical means allows the self-locking hanger 30 to be easily stowed when not in use, without occupying additional space, and also facilitates users to quickly deploy when needed.

[0079] The self-locking hanger 30 is designed with an adjustable inclination angle to adapt to the placement and removal of the guitar. When the guitar is not placed on the hanger, the hanger maintains an inclination angle ranging from 15 to 22 degrees, with 19 degrees being the optimal angle. This angle provides a natural placement and removal path for the guitar. This angle range allows the guitar to easily slide into the U-shaped slot r.

[0080] In addition, the inclination angle helps the hanger respond quickly to the gravity of the guitar placed on it. When the guitar is placed on the hanger, the inclination angle of the hanger helps the gravity act on the locking block 50, causing it to quickly close and lock the guitar.

[0081] The inclination angle of the hanger allows for fine-tuning the contact angle with the guitar in different usage states, ensuring stable and gentle contact between the hanger and the guitar. This fine-tuning capability is based on the design of the waist-shaped hole p, which provides the necessary degree of freedom for the transmission member 41 to move accurately along the thickness direction of the inner cavity of the shell 31. This precise movement capability is crucial for achieving quick locking and releasing of the guitar, while also ensuring the hanger's sensitive response to guitar placement and removal actions.

[0082] The inclination range of the hanger, combined with the fine-tuning function of the waist-shaped hole p, significantly enhances the performance of the hanger. The design of the inclination range allows the hanger to adapt to the placement and removal of the guitar, while the waist-shaped hole p allows fine-tuning without additional mechanical pressure. This technical means reduces the hard wear and tear of the hanger when it comes into contact with the guitar, prolongs the service life of the hanger, and provides a more smooth and worry-free use experience. Through this synergy, the hanger can better fit the shape of the guitar, maintaining stability and ease of use when placing or removing the guitar.

[0083] In summary, the vertical movement of the transmission member 41 and the automatic reset function of the first spring f enable the hanger to quickly respond to the placement and removal of the guitar. The design of the waist-shaped hole p allows the transmission member 41 to move without hard constraints, reducing wear and tear caused by hard contact and friction.

[0084] When the guitar is placed into the self-locking hanger 30, the inclination angle of the self-locking hanger 30 is 1-3 degrees, preferably actually 2 degrees.

[0085] Preferably, the angle a is 15-19 degrees, preferably 17 degrees. The design of the preferred angle is to enable the self-locking mechanism to quickly respond to the placement of the guitar, achieve quick locking or release, and ensure stable contact between the guitar neck and the hanger.

[0086] In addition, the top of the cylindrical part 11 is provided with a rotatable hanging rod 13, and the top of the cylindrical part 11 is provided with a groove 14; the hanging rod 13 can switch between being accommodated in the groove 14 and being in a vertical position. The hanging rod 13 can rotate and switch positions, allowing users to adjust the direction and use of the hanging rod as needed, thereby achieving multiple mounting. When the hanging rod 13 is in a vertical position, it can mount a guitar bag.

[0087] By allowing the hanging rod 13 to move in the groove 14 and switch between vertical positions, the space at the top of the cylindrical part 11 is maximized, whether it needs to be mounted with a guitar or needs to be retracted to save space.

[0088] When the hanging rod is not needed, it can be turned to a vertical position or retracted into the groove 14, reducing the risk of accidental collision or injury and improving safety.

[0089] Further, the top of the side seat 12 is provided with a slot 18 for inserting guitar picks. This provides a convenient place to store guitar picks, ensuring that the picks are easily accessible while avoiding loss or misplacement.

[0090] The gravity self-locking guitar stand 100 further includes a support frame 200, which comprises a base 201 and a support rod 202. The top of the support rod 202 extends into the cylindrical portion 11. The support frame 200 provides additional support points for the guitar stand 100, effectively enhancing the stability of the entire structure and ensuring that the guitar stand is more stable during use and less likely to tip over.

[0091] The addition of the support frame 200 allows the guitar stand 100 to better distribute and bear the weight of the guitar, improving the load-bearing capacity of the guitar stand and maintaining stability even when a heavier guitar is mounted.

[0092] The top of the support rod 202 extends into the cylindrical portion 11, which helps optimize the stress distribution of the guitar stand 100, reducing local stress concentration and thus improving the durability and service life of the entire structure.

[0093] More specifically, the center of the first connecting portion 31 of the connector 30 has an axle hole c5, which is provided with a first gear slot 01 and a second gear slot 02.

[0094] The knob assembly 60 includes a knob 61, a rotating latch 62, and a second spring 63. The rotating latch 62 is provided with a gear rib 63 that matches the gear slot, and the second spring 63 is threaded onto the rotating latch 61.

[0095] By rotating the knob 61 and the rotating latch 62, the gear rib 63 can be inserted into different gear slots, allowing the self-locking hanger 30 to be in a use state and a storage state.

[0096] The first gear slot 01 and the second gear slot 02 on the axle hole c5 allow the connector 30 to be fixed at different positions and angles, thereby adapting to the needs of different users and different use scenarios. The combination of the knob 61 and the rotating latch 62 allows users to quickly switch the self-locking hanger 30 from the use state to the storage state or vice versa through simple knob operation, improving the convenience of operation.

[0097] The matching design of the gear rib 63 on the rotating latch 62 and the gear slot ensures that the self-locking hanger 30 can be securely locked at the selected gear, preventing accidental sliding or displacement during use. The design of the knob assembly 60 simplifies the user's operation process, allowing users to easily adjust the gear through the knob without the need for additional tools or complex steps, improving user experience.

[0098] Preferably, the inner wall of the U-shaped slot r of the self-locking hanger 30 and the inner side of the lock block 50 are provided with soft pads. The soft pads can provide additional protection for the guitar, avoiding scratches or damage to the surface of the guitar caused by the hard contact surface of the hanger or the lock block when placing or taking out the guitar.
