DETAILED DESCRIPTION
[0021] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.
[0022] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0023] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] See also Figure 1 As shown, an embodiment of the present application discloses a foldable guitar stand, including a fixing seat and two support rods. For the convenience of description below, the two support rods are defined as a first support rod and a second support rod, and the first support rod and the second support rod have the same structure.
[0025] Participate in the Figure 2 , 3 The fixing seat comprises a base 1 and a cover plate 2, wherein the base 1 is provided with a mounting groove 3 with a front opening and a lower opening, the upper ends of the two support rods are fitted in the mounting groove 3 in an inverted V shape, and the cover plate 2 covers the front opening of the base 1, and a first connecting member and a second connecting member are passed through the cover plate 2, wherein the first connecting member is used to fix the first support rod in the mounting groove 3, and the second connecting member is movably passed through the second support rod and connected to the base 1, so that the second support rod can be opened or retracted relative to the first support rod, that is, the second connecting member can serve as a rotating shaft for the second support rod to rotate in the mounting groove 3; in addition, a positioning pin 4 and an actuator for driving the positioning pin 4 to extend and retract in the front-to-back direction are protrudingly provided on the front side wall and / or the rear side plate of the second support rod, and a plurality of positioning holes 5 are provided on the rear side plate of the cover plate 2 and / or the base 1, and the actuator is used to drive the positioning pin 4 to be fitted to any positioning hole 5, so as to realize the limitation of relative rotation of the first support rod and the second support rod to a plurality of angular positions.
[0026] In this embodiment, in order to consider the aesthetics, the positioning pin 4 and the positioning socket 5 are arranged on the rear side of the guitar stand, that is, the positioning socket 5 is opened on the rear side plate of the base 1, and the outer end of the positioning pin 4 extends out of the rear side plate of the second support rod. Specifically, when it is necessary to adjust the angle between the second support rod and the first support rod, the actuator is driven by external force, so that the positioning pin 4 is extended and retracted along the front and rear direction of the second support rod, that is, when the positioning pin 4 is retracted inward, it loses the restriction on the rotation of the second support rod, and the second support rod can be opened or retracted in the left and right direction. When the second support rod moves to the set position, the brake member drives the positioning pin 4 to reset outward until it is inserted and fitted into the positioning socket 5 at the corresponding position on the base 1.
[0027] In the above structure, more specifically, the first connecting member includes two first bolts 8 arranged at intervals along the length direction of the first support rod, two first connecting columns 9 are protrudingly arranged on the rear side plate of the mounting groove 3, and two first connecting holes 10 are provided at the upper end of the first support rod. The two first connecting columns 9 are respectively inserted and fitted in the two first connecting holes 10, and the two first bolts 8 are respectively connected to the two first connecting columns 9. In this structure, after the mounting groove 3 is set on the base 1, the thickness of its rear side plate is insufficient and cannot be directly connected and fixed by the first bolts 8. Therefore, the first bolts 8 are fixed by the first connecting columns 9 to ensure the connection strength between the cover plate 2 and the base 1, and the fixed connection of the first support rod in the mounting groove 3 is realized while the cover plate 2 is connected to the base 1.
[0028] In addition, the second connecting member includes a second bolt 11 and a third bolt 12, and a second connecting column 13 and a third connecting column 14 are also protrudingly provided on the rear side plate of the mounting groove 3. The upper end of the second support rod is provided with a second connecting hole 15 and a third connecting hole spaced apart along its length direction, and the second connecting column 13 is movably inserted into the second connecting hole 15; a notch connected to the third connecting hole is provided on the outer wall of the second support rod away from the first support rod to form a U-shaped groove 16, and the third connecting column 14 can be movably mounted in the U-shaped groove 16, and the second bolt 11 and the third bolt 12 are respectively connected to the second connecting column 13 and the third connecting column 14. In this structure, the second connecting column 13 and the third connecting column 14 are also for realizing the fixed connection of the corresponding bolts and improving the structural strength; and the second support rod needs to rotate, so two closed connecting holes cannot be set like the first support rod. The second connecting hole 15 set in this structure is for the second connecting column 13 to cooperate flexibly. The second connecting column 13 here acts as a rotating shaft, and the third connecting column 14 is to increase the strength of the connection structure of the first support rod, the second support rod, the cover plate 2 and the base 1 in the entire structure. The third connecting column 14 cannot interfere with the rotation of the second support rod. For this reason, in this embodiment, a corresponding U-shaped groove 16 is opened on the front wall of the second support rod. The third connecting column 14 can be accommodated in the U-shaped groove 16 and can also be easily detached from it, which is convenient for the rotation of the second support rod.
[0029] In this embodiment, in order to further improve the strength of the connection structure between the cover plate 2 and the base 1, four positioning columns 17 are protrudingly arranged on the inner wall of the cover plate 2 near the mounting groove 3, and are respectively abutted with the first connecting column 9, the second connecting column 13, and the third connecting column 14. The outer ends of the four positioning columns 17 are protrudingly provided with limiting bosses 18. The outer ends of the two first connecting columns 9, the second connecting columns 13 and the third connecting column 14 are all concavely provided with limiting grooves 19 respectively inserted and matched with the four limiting bosses 18. The four positioning columns 17 are all provided with mounting holes for corresponding bolts to pass through. When multiple bolts are connected and fixed, the cover plate 2 and the base 1 are axially abutted by the positioning columns 17 and the connecting columns to avoid deformation of the cover plate 2 and the rear side plate of the base 1; and the setting of the limiting bosses 18 and the limiting grooves 19 realizes the limitation of the connection position between the cover plate 2 and the base 1, ensuring that when the two components are covered, each bolt can be smoothly aligned with the threaded hole on the outer end face of the corresponding connecting column, thereby improving the installation efficiency.
[0030] On the other hand, in the above structure, after the cover plate 2 is connected to the base 1, the outer end surface of the bolt can be seen on the cover plate 2 on the front side of the fixing seat. Therefore, in this embodiment, a layer of EVA pad 51 is bonded to the front side wall of the cover plate 2. In actual use, when the guitar is placed on the support arm 50 at the lower end of the guitar stand, the upper end of the guitar directly contacts and abuts against the EVA pad 51. The EVA pad 51 not only plays the role of shielding the fastener, but also plays the role of shockproof and buffering, preventing the outer surface of the guitar from directly contacting the fixing seat and causing wear.
[0031] In the above structure, preferably, the actuator includes a V-shaped spring piece 20, and a accommodating cavity is provided on the upper part of the second support rod. The V-shaped spring piece 20 is opened upward and is deformably installed in the accommodating cavity along the front and rear direction of the second support rod. The positioning pin 4 is connected to the upper end of the front side plate of the V-shaped spring piece 20, and the lower end of the front side plate of the V-shaped spring piece 20 is connected to the pressure rod 21. The front wall of the upper end of the second support rod is provided with an avoidance hole 22 for the positioning pin 4 and the pressure rod 21 to pass through respectively, and the outer end of the pressure rod 21 passing through the avoidance hole 22 is connected to a pressure cover 23, which can prevent the outer end of the pressure rod 21 from being completely retracted into the accommodating cavity, resulting in the subsequent inability to press the pressure rod 21.
[0032] More specifically, in this embodiment, see the attached Figure 4 The positioning pin 4 and the pressure rod 21 are fixed on the V-shaped spring piece 20 by welding or riveting, so the pressure rod 121 in this structure is also a metal part. In order to increase the aesthetics, the above-mentioned pressure cover 23 is a plastic part, and the inner end of the pressure cover 23 is inserted and matched with the pressure rod 21. In addition, during use, the V-shaped spring piece 20 can be deformed by pressing the pressure cover 23, and the positioning pin 4 can be retracted into the accommodating cavity, thereby releasing the limit on the second support rod. At this time, the second support rod can rotate left and right. When it rotates to the set position, the pressure cover 23 is released. After the external force is lost, the V-shaped spring piece 20 is reset, and the positioning pin 4 is inserted and positioned in the positioning socket 5 at the corresponding position on the rear side plate of the base 1 again.
[0033] In this embodiment, preferably, see the attached Figure 3 A large hole and three small holes are provided on the rear side plate of the base 1. The three small holes have the same diameter and are used as the positioning pin 4 for insertion and positioning when the second support rod is rotated to the use position; while the large hole is mainly used as the positioning pin 4 for insertion and positioning when the second support rod is rotated to the storage position.
[0034] In addition, in this embodiment, see the attached Figure 1 And attached Figures 5 to 8The second rod body 7 can be rotated downward in the front-to-back direction to a use position in the same straight line as the first rod body 6, and can be rotated upward to a storage position at a certain angle to the first rod body 6. Specifically, an L-shaped connecting portion 24 is provided at the top of the second rod body 7, and an inverted L-shaped connecting portion 25 matching the L-shaped connecting portion 24 is provided at the lower end of the first rod body 6, that is, when connected, the L-shaped connecting portion 24 and the inverted L-shaped connecting portion 25 are relatively embedded, and the first vertical plate 26 of the L-shaped connecting portion 24 and the second vertical plate 27 of the inverted L-shaped connecting portion 25 are rotatably connected through a hinge shaft 28, so that the second rod body 7 can be rotated downward in the front-to-back direction to be aligned with the first rod body 6. The support rod 6 can be in a use position located in the same straight line, and in a storage position rotated upward to form a certain angle with the first rod body 6. In this structure, when the first rod body 6 and the second rod body 7 are rotated and connected, the outer peripheral walls of the two are in the same plane, ensuring a beautiful appearance. In the above structure, a positioning component is provided between the first rod body 6 and the second rod body 7 for preventing the support rod from rotating forward and backward when in the use position, that is, when the second rod body 7 is rotated to be in the same straight line with the first rod body 6, it is difficult to continue to rotate under the action of the positioning component. Similarly, when storing, the second rod body 7 cannot continue to rotate when it is rotated to a state of approximately 90° with the first rod body 6, thereby ensuring the stability of the bracket in the two states.
[0035] For more details, see the attached Figure 5 The front end of the top of the first vertical plate 26 and the front end of the bottom of the second vertical plate 27 are respectively provided with a first arc-shaped protrusion 29 and a second arc-shaped protrusion 30. Correspondingly, the first horizontal plate 31 of the L-shaped connecting part 24 is provided with a first arc-shaped groove 32 that slides with the second arc-shaped protrusion 30, and the second horizontal plate 33 of the inverted L-shaped connecting part 25 is provided with a second arc-shaped groove 34 that slides with the first arc-shaped protrusion 29. The arc-shaped matching surface can play a certain guiding role to improve the stability of the second rod body 7 and the first rod body 6 during rotation.
[0036] In addition, in the above structure, see the attached Figure 5 , 6 A first abutment surface 35 is provided at the rear end of the top of the first vertical plate 26 and the rear end of the first horizontal plate 31, and the first abutment surface 35 is connected with one side of the first arc-shaped protrusion 29 or the first arc-shaped groove 32, and the highest point of the first arc-shaped protrusion 29 is higher than the first abutment surface 35, and the lowest point of the first arc-shaped groove 32 is lower than the first abutment surface 35; similarly, a second abutment surface 36 is provided at the rear end of the bottom of the second vertical plate 27 and the rear end of the second horizontal plate 33, the highest point of the second arc-shaped protrusion 30 is higher than the second abutment surface 36, and the lowest point of the second arc-shaped groove 34 is lower than the second abutment surface 36; and when the support rod is in the use position, each first abutment surface 35 is respectively abutted and limited with each second abutment surface 36 to achieve backward anti-rotation positioning.
[0037] See the attached Figures 5 to 7 A positioning hole 37 is provided on the inner wall of the first vertical plate 26, and a positioning protrusion 38 is provided on the inner wall of the second vertical plate 27. When the support rod is in the use position, the positioning protrusion 38 matches the positioning hole 37 to achieve forward anti-rotation positioning.
[0038] In this embodiment, preferably, the first rod body 6 and the second rod body 7 are both hollow square tubes made of metal, the upper end of the second rod body 7 is connected to a male fixing seat 39 made of plastic material, and the lower end of the first rod body 6 is connected to a female fixing seat 40 made of plastic material, and the L-shaped connecting portion 24 and the inverted L-shaped connecting portion 25 are respectively formed on the male fixing seat 39 and the female fixing seat 40, that is, the male fixing seat 39 has an overall L-shaped structure, and the female fixing seat 40 has an overall inverted L-shaped structure.
[0039] See the attached Figures 7 to 9 , a positioning pin 41 is protruding on the inner side wall of the first vertical plate 26, and a positioning tube 42 is protruding on the inner side wall of the second vertical plate 27, which is inserted into and matched with the positioning pin 41 and can rotate relatively; a first connecting plate 43 and a second connecting plate 44 corresponding to the first vertical plate 26 and the second vertical plate 27 are provided on the top of the second rod body 7 and the bottom of the first rod body 6; the first connecting plate 43 and the second connecting plate 44 here are not horizontal plate structures, but U-shaped protective plate structures wrapped around the outside of the first vertical plate 26 and the second vertical plate 27, and the axial end face shape of the protective plate structure is the same as the axial end face structure of each vertical plate and is flush with each other, that is, the fixed seat structure is not visible from the left side of the second rod body 7 and the right side of the first rod body 6, thereby ensuring the integrity and aesthetics of the appearance; therefore, in this structure, the hinge shaft 28 is sequentially arranged in the first connecting plate 43, the positioning pin 41, the positioning tube 42 and the second connecting plate 44.
[0040] In this embodiment, preferably, the hinge shaft 28 is a riveted rod, that is, the rotational connection between the first rod body 6 and the second rod body 7 is achieved through a riveting process, and the processing technology is simpler and more efficient.
[0041] In some other embodiments, the hinge shaft 28 may also adopt a structure in which a bolt and a nut cooperate with each other.
[0042] Preferably, the outer wall of the positioning column 41 is a conical surface whose diameter gradually decreases in the direction away from the first vertical plate 26, and the inner hole of the positioning tube 42 is a conical surface matching the outer wall of the positioning column 41. The mating surface of the conical structure can increase the friction resistance of the relative rotation between the second rod body 7 and the first rod body 6 after connection, and on the other hand increase the stability of the support rod when it is in use.
[0043] In this embodiment, the outer wall of the second vertical plate 27 and located above the positioning plug 42 is recessed inward to form a columnar protrusion 45, and the outer wall of the columnar protrusion 45 near the first vertical plate 26 is convexly formed with an arc-shaped convex block to form a positioning protrusion 38; the inner wall of the first vertical plate 26 and located above the positioning plug 41 is convexly provided with a support column 46, and the outer end surface of the support column 46 is concave to form a positioning hole 37, for details, see the attached Figure 5 , 6 In this structure, the positioning protrusion 38 is arranged on the end face of the hollow boss 45, so that it is easier to reversely deform after being subjected to force, that is, when the second rod body 7 is rotated to the use position, or when it is ready to be rotated from the use position toward the storage position, the positioning protrusion 38 can better slide and fit into the positioning hole 37 or detach from the positioning hole 37.
[0044] On the other hand, see Appendix Figure 5 , 6 An arc-shaped guide rib 47 is also protruding on the inner side wall of the first vertical plate 26, and one end of the guide rib 47 extends to the outer wall of the support column 46. When the second rod body 7 and the first rod body 6 rotate relative to each other, the positioning protrusion 38 can better slide along the outer end surface of the guide rib 47, and can more easily fit into the positioning hole 37 or disengage from the positioning hole 37, thereby ensuring the stability of the relative rotation between the second rod body 7 and the first rod body 6.
[0045] In addition, see Appendix Figure 1 The lower ends of the two second rod bodies 7 are connected to a horizontal support crossbar 48, and both ends of the two support crossbars 48 are equipped with anti-slip foot covers 49. The front side walls of the two second rod bodies 7 are connected to a support arm 50 for supporting the guitar, and the outside of the two support arms 50 is equipped with protective foam to prevent the bottom of the guitar from being scratched.
