When the guitar is not placed on the hanger, the first spring keeps the transmission component at the bottom position, and the lock block is in an open state, which is convenient for placing the guitar. When the guitar is placed in the U-shaped groove, the deadweight of the hanger causes the lock block to automatically close, achieving stable fixation of the guitar. This automated process reduces the complexity of user operation and ensures the safety of the guitar.

[0035] In addition, the geometric characteristics of the waist-shaped hole allow a certain degree of axial and angular adjustment. This degree of freedom allows the transmission member to move along a fixed thickness direction while avoiding the hard friction present in traditional mechanical structures; thereby achieving the goal of moving the transmission member without hard constraints, reducing wear caused by hard contact and friction. In addition, the vertical movement of the transmission member relative to the inner cavity and the automatic reset function of the first spring enable the hanger to quickly respond to the placement and removal of the guitar.

[0036] Secondly, the connector allows the self-locking hanger to rotate to a vertical position when not in use, close to the side seat, saving space and facilitating storage. At the same time, the linear layout of the first connection part, the second connection part and the third connection part ensures the stability and reliability of the hanger, so that the hanger can smoothly transition to the desired position during the rotation process, whether it is in use or in storage.

[0037] Finally, the technical solution also takes into account the user experience in details, such as setting soft pads on the inner wall of the U-shaped groove of the self-locking hanger and the inner side of the lock block to prevent scratches or damage to the guitar. In addition, by precisely controlling the tilt angle and rotation angle of the hanger, the smoothness and stability of the guitar when placing and taking it out are ensured. Overall, this gravity self-locking guitar stand not only improves the safety and stability of guitar storage, but also optimizes the user's operating experience, making it more user-friendly and practical.

[0058] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0059] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0060] Embodiment 1

[0061] A gravity self-locking guitar stand 100 includes 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 to form a stable and easy-to-operate structure.

[0062] The self-locking hanger 30 is composed of a housing 31, in which a transmission assembly 40 and a locking block 50 are installed. Specifically, the self-locking hanger 30 is composed of a base 32 and two extended support arms 33, wherein the locking block 50 is located at the front end of the support arm 33. The base 32 and the support arm 33 together form a U-shaped groove r, which is specially designed to fix the neck of the guitar. This design makes the hanger easy to operate while ensuring the safety of the guitar.

[0063] The transmission assembly 40 includes a transmission member 41 that moves vertically 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 at the rear side of the block d1. The transmission shaft 42 is provided with a gear d4 that cooperates with the vertical rack d2. The front end of the transmission shaft 42 extends out of the support arm 33 and is connected to the locking block 50. A first spring f is arranged between the transmission member 41 and the inner side of the top wall of the shell 31. Figure 7 and Figure 8 As shown, the function of the first spring f is to enable the transmission member 41 to automatically reset.

[0064] The transmission method between the transmission member 41 and the transmission shaft 42 can also be an eccentric mechanism to convert the linear motion of the transmission mechanism into the rotation of the transmission shaft.

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

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

[0067] like Figure 7 As shown, the guitar is not placed on the self-locking hanger 30, and 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 tilted upward and the locking block 50 is in an open state.

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

[0069] The technical effects of the technical means include: the design of the gravity self-locking guitar stand 100 cleverly utilizes the principle of mechanics, and 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 on the hanger, the first spring f keeps the transmission member 41 at the bottom position, and the lock block 50 remains in the open state, which is convenient for placing the guitar. It ensures that the hanger can maintain a ready state even without external operation.

[0070] Once the guitar is placed in the U-shaped groove r, the self-locking hanger 30 senses the gravity of the guitar and activates the locking mechanism by rotating a certain angle a. During this process, the first spring f is compressed, the transmission member 41 moves upward, and the rotation of the transmission shaft 42 drives the locking 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 to prevent it from accidentally slipping.

[0071] In general, the gravity self-locking guitar stand 100 provides a solution that can automatically adapt to the placement and removal of the guitar without additional operation through an 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 extends the service life of the product by reducing the dependence on external forces, while maintaining the simplicity of operation and the stability of the hanger.

[0072] Preferably, a guide groove h in the thickness direction is provided in the inner cavity of the housing 31 where the base 32 is located, 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 walls h1 provide a precise moving path for the transmission member 41, ensuring that its vertical movement is smoother and more accurate. This precise guiding action reduces the movement deviation caused by friction or tilt, thereby improving the response speed and reliability of the entire self-locking system.

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

[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 enables the transmission member 41 to move along the thickness direction of the inner cavity without relying on a complex guide mechanism. This avoids the wear and jam caused by the transmission member 41 moving under rigid constraints in the traditional structure. This ensures that the locking block 50 can respond quickly and accurately, achieves rapid locking and release, and optimizes the user experience.

[0075] A shelf v is provided on the top wall of the housing 31, and the shelf v is used to place the transmission shaft 42, and an axial limiting structure v1 is provided on the transmission shaft 42 to limit the axial movement of the transmission shaft 42. The shelf v provides a stable support point for the transmission shaft 42, ensuring that the transmission shaft maintains a correct position in the vertical direction. When the guitar is placed or removed, the axial limiting structure v1 ensures that the locking block 50 can accurately perform locking and releasing operations, thereby improving the safety of the entire self-locking system.

[0076] The design of the base 10, which is composed of a cylindrical portion 11 with a closed upper end and an open 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 portion 11 not only enhances the overall load-bearing capacity, but also helps to disperse and reduce vibration, ensuring the stability and durability of the guitar stand when in use. The design of the side seat 12 cleverly provides an axial connection point for the first connecting portion 31 of the connector 30, making the assembly and maintenance process simple and quick. In addition, the application of the knob assembly 60 provides users with a reliable fixing solution to ensure that the connection between the connector and the base remains firm under various conditions of use, thereby enhancing the safety and reliability of the entire guitar stand.

[0077] With the above technical means, the guitar stand 100 achieves a compact and beautiful structure, while optimizing mechanical distribution, reducing local stress concentration, and extending the service life of the product. The easy adjustability of the knob assembly 60 also allows the user to make fine adjustments according to different usage scenarios to achieve the best usage experience.

[0078] The self-locking hanger 30 has two states: use and storage, which can be quickly switched according to needs. In the storage state, the hanger 30 can be neatly hung under the side seat 12 through the connector 30, which saves space and maintains the neat appearance of the guitar stand. This technical means allows the self-locking hanger 30 to be easily folded up when not in use without taking up extra space, and it is also convenient for users to quickly unfold and use it when needed.

[0079] The self-locking hanger 30 is designed with an adjustable tilt angle to accommodate the placement and removal of the guitar. When the guitar is not placed on the hanger, the hanger maintains a tilt 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 slide easily into the U-shaped groove.

[0080] In addition, the angle of inclination helps the rack to respond quickly to the gravity of the guitar. When the guitar is placed on the rack, the angle of inclination of the rack helps gravity act on the locking block 50, so that it closes quickly and locks the guitar.

[0081] The tilt angle design of the hanger allows fine adjustment of the contact angle with the guitar under different usage conditions, ensuring that the contact between the hanger and the guitar is both stable and gentle. This fine adjustment capability is based on the design of the waist-shaped hole p, which provides the necessary degree of freedom to enable the transmission member 41 to move accurately along the thickness direction of the inner cavity of the shell 31. This precise movement capability is the key to achieving rapid locking and release of the guitar, and also ensures that the hanger responds sensitively to the placement and removal of the guitar.

[0082] The combination of the hanger's tilt and the fine-tuning capabilities of the waist-shaped hole p significantly improves the hanger's performance. The tilt allows the hanger to adapt to the placement and removal of the guitar, while the waist-shaped hole p allows for fine-tuning without adding additional mechanical pressure. This technical approach reduces hard wear when the hanger contacts the guitar, extending the life of the hanger and providing a smoother and worry-free experience. Through this synergy, the hanger can better fit the shape of the guitar, maintaining stability and ease 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 caused by hard contact and friction.

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

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

[0086] In addition, a rotatable hanging rod 13 is provided at the top of the cylindrical portion 11, and a groove 14 is provided at the top of the cylindrical portion 11; the hanging rod 13 can be switched between being accommodated in the groove 14 and being in a vertical position. The hanging rod 13 can be rotated and switched in position, so that the user can adjust the direction and usage of the hanging rod as needed, thereby achieving a variety of mounting. When the hanging rod 13 is in a vertical position, a guitar bag can be mounted.

[0087] By allowing the hanging rod 13 to move in the groove 14 and switch the vertical position, the space at the top of the cylindrical portion 11 is utilized to the maximum extent, whether a guitar needs to be mounted or the hanging rod needs to be folded up to save space.

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

[0089] Further, a slot 18 for inserting a guitar pick is provided on the top of the side seat 12. A convenient place is provided to store the guitar pick, ensuring that the pick is easy to obtain while avoiding loss or misplacing.

[0090] A gravity self-locking guitar stand 100 also includes a support frame 200, which includes a base 201 and a support rod 202, and the top of the support rod 202 extends into the cylindrical body 11. The support frame 200 provides an additional support point for the guitar stand 100 through the base 201 and the support rod 202, effectively enhancing the stability of the entire structure, ensuring that the guitar stand is more stable during use and is not easy to tip over.

[0091] The addition of the support frame 200 enables the guitar stand 100 to better disperse and bear the weight of the guitar, thereby 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 body 11, which helps to optimize the stress distribution of the guitar stand 100 and reduce local stress concentration, thereby 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 axial hole c5 , and the axial hole c5 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 matching the gear slot, and the second spring 63 is passed through the rotating latch 61 .

[0095] The shift rib 63 can be inserted into different shift slots through the knob 61 and the rotating latch 62, so that the self-locking hanger 30 is in a use state and a storage state.

[0096] The first gear slot 01 and the second gear slot 02 on the shaft hole c5 allow the connector 30 to be fixed at different positions and angles, so as to meet the needs of different users and different usage scenarios. The coordinated use of the knob 61 and the rotating latch 62 allows the user to quickly switch the self-locking hanger 30 from the use state to the storage state, or vice versa, by simply turning the knob, thereby 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 bracket 30 can be firmly locked at the selected gear position to prevent accidental sliding or displacement during use. The design of the knob assembly 60 simplifies the user's operation process. The user can easily adjust the gear position by turning the knob without additional tools or complicated steps, thereby improving the user experience.

[0098] Preferably, the inner wall of the U-shaped groove r of the self-locking hanger 30 and the inner side of the locking block 50 are provided with a soft pad. The soft pad 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 locking block when placing or taking out the guitar. In addition, the soft pad can absorb and reduce the vibration and noise generated when the guitar contacts the hanger, providing a quieter use experience.

[0099] Embodiment 2

[0100] Furthermore, another technical means for achieving the technical purpose of the present invention is as follows:

[0101] Other technical means have been described in detail above and will not be repeated here. The self-locking structure in this technical means is as follows: Figures 16 to 19 As shown, the transmission components 41 and the transmission shaft 42 are transmitted via an eccentric mechanism 90 ; the eccentric mechanism 90 includes an eccentric shaft 91 at the rear end of the transmission shaft 42 and clamping grooves 92 provided on both sides of the block d1 .

[0102] The clamping groove 92 extends laterally along the length direction of the block body d1, and the eccentric shaft 91 is located in the clamping groove 92 and can move in the clamping groove 92; when the transmission member 41 moves up and down relative to the shell 31, the clamping groove 92 drives the eccentric shaft 91 to rotate, and then drives the transmission shaft 42 to rotate, and finally realizes the opening or closing of the locking block 50.

[0103] A first disc c1 is disposed at the rear end of the transmission shaft 42, and an eccentric shaft 91 is eccentrically disposed on the rear end surface of the first disc c1; a second disc c2 is disposed at the rear end of the eccentric shaft 91, and a resting portion c3 is extended outwardly from the rear end of the second disc c2.
