[0004] However, in the aforementioned patent, the space occupied when not in use is reduced by folding the legs. Although this can reduce the space occupied, the horizontal support above cannot be folded in the center, which limits the overall compactness of storage and causes inconvenience and certain limitations in use.

[0005] Therefore, a foldable portable guzheng stand is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a foldable portable guzheng stand to solve the problems mentioned in the background art.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A foldable portable guzheng stand includes two bases, which are rotatably connected by a hinge. Each of the two bases has a sliding limit rod inside. One base has three sliding limit rods, and the other base has two sliding limit rods. All five limit rods are inserted into one side of the base facing the opposite direction. Each of the two bases has a plectrum inside, and both plectrums are fixedly connected to the sliding limit rods inside the base.

[0011] Furthermore, each of the two bases is rotatably connected to a support leg, each of the four support legs is rotatably connected to a connecting rod on one side above each of the four connecting rods, and each of the four sliding blocks is rotatably connected to the inside of the base.

[0012] Furthermore, each of the four sliding blocks has a pin inserted above it, and each of the four pins is inserted into the upper part of the base. Each of the four pins has a threaded line below it.

[0013] Furthermore, storage holes are provided on both sides of the two bases, and threaded lines are provided inside the four storage holes.

[0014] Furthermore, all four pins are inserted into the inside of the receiving hole, and the threaded lines at the bottom of the pins are of the same specification as the threaded lines inside the receiving hole.

[0015] Furthermore, each of the four support legs has a threaded sleeve rotatably connected to its lower interior, and each of the four threaded sleeves has a knob fixedly connected to its upper interior. Part of the outer wall of each of the four knobs is located outside the support leg.

[0016] Furthermore, each of the four threaded sleeves is rotatably connected to a threaded rod, and each of the four threaded rods is fixedly connected to a foot, with each of the four feet slidably connected to a support leg.

[0017] Furthermore, a level is installed on one side of one of the bases, magnets are fixedly connected to the lower side of one side of the four support legs and the lower side of the two bases, a placement plate is fixedly connected to the upper side of the two bases, a music score placement block is fixedly connected to one side of the two bases, and a U-shaped groove is opened on the upper side of the two music score placement blocks.

[0018] 3. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] (1) In this solution, the guzheng stand uses hinges to connect the two bases, which can be folded freely. The stand, which originally occupied a large space, can be instantly reduced to a compact flat shape, which meets the needs of performers who frequently travel to different venues such as performances and teaching. Whether it is stuffed into a small car trunk or taken on public transportation, it is easy and convenient. The support legs can be rotated and retracted flexibly. With the cleverly designed pins, they can be accurately inserted into the storage holes, so that when the stand is stored, all parts fit tightly together and the whole is neat and orderly. This effectively avoids damage caused by shaking and collision of parts, further improving portability and reducing the burden of moving.

[0021] (2) In this solution, when used on uneven ground, the height of the feet can be adjusted to keep the bracket level and stable, avoiding the guzheng from shaking due to uneven ground and affecting the performance. At the same time, the rubber feet can effectively reduce the wear and tear of the bracket on the ground and protect the ground where it is placed. A high-precision bubble level installed on one side of the base can intuitively and accurately display the level status of the bracket. When setting up the guzheng bracket, the user can quickly adjust the angle of the support legs and the height of the feet by observing the level to ensure that the bracket is in a level position. This is crucial for guzheng performance. A level bracket can ensure that the string tension is uniform, making the tone of the guzheng more accurate and stable, and improving the performance effect.

[0022] (3) In this scheme, after the five limit rods slide to the limit position, they are inserted into the base side in the direction directly opposite to them, forming a stable connection structure. This not only enhances the connection strength between the two bases, but also prevents the two bases from shifting relative to each other during the placement and use of the guzheng, ensuring the stability of the guzheng placement and effectively avoiding the impact of the support shaking on the performance.

[0035] Example 1

[0036] Please see Figure 1-7 A foldable portable guzheng stand includes two bases 1, which are rotatably connected by a hinge 25. Each base 1 has sliding limit rods 23 slidably connected inside it. One base 1 has three sliding limit rods 23, and the other base 1 has two. All five limit rods 23 are inserted into one side of the base 1 facing the opposite direction. Each base 1 has a plectrum 24 inside it, and both plectrums 24 are fixedly connected to the sliding limit rods 23 inside the base 1.

[0037] In this embodiment, the two bases 1 are connected by a rotatable hinge 25. The hinge 25 is made of stainless steel, which gives the bracket excellent rust resistance and durability. During long-term use, whether in a humid indoor environment or when frequently carried out and facing different climatic conditions, the stainless steel hinge 25 can effectively resist corrosion, ensuring that the opening and closing function of the bracket always operates normally, greatly extending the service life of the bracket. At the same time, the rotation angle range of the hinge 25 is from 0° to 180°, which allows the two bases 1 to open and close flexibly. When stored, the two bases 1 can be completely folded and snug, greatly reducing the space occupied by the bracket and making it convenient for users to carry and store. It is especially suitable for people who often need to move to different places for guzheng performance or teaching. When unfolded, the 180° rotation angle ensures that the bracket can be placed stably on various flat surfaces, meeting the placement needs of different scenarios.

[0038] Sliding limiting rods 23 are installed inside the two bases 1, with three in one base 1 and two in the other. This design achieves multi-directional limiting function. When the bracket is unfolded and in use, the five limiting rods 23 slide to their limit positions and then insert into the base 1 on the opposite side, forming a stable connection structure. This not only enhances the connection strength between the two bases 1 and prevents relative displacement between the two bases 1 during the placement and use of the guzheng, ensuring the stability of the guzheng and effectively avoiding the impact of bracket wobbling on the performance, but also the rubber anti-slip sleeves on the insertion ends of the limiting rods 23 further increase the friction of the insertion parts. Even on uneven ground or when subjected to slight external impact, the bracket can maintain its stability, reducing the risk of the guzheng tipping over and being damaged due to bracket instability.

[0039] Both bases 1 are equipped with paddles 24 inside, and the paddles 24 are fixedly connected to the sliding limit rods 23 inside the bases 1 by welding. This provides great convenience for users to operate the limit rods 23. When users need to unfold or store the bracket, they do not need to use other tools. They can easily move the limit rods 23 inside the bases 1 by gently plucking the paddles 24. The paddles 24, made of high-strength plastic, have good toughness and strength, which not only ensures that they are not easily damaged under frequent plucking operations, but also do not increase the overall weight of the bracket due to their light material. This convenient operation method allows users to complete the unfolding and storage of the bracket in a short time, improving the efficiency of the bracket. It is especially suitable for situations where equipment needs to be quickly set up and packed up at performance or teaching sites.

[0040] Example 2

[0041] Please see Figure 1-7A foldable portable guzheng stand includes two bases 1, each with a supporting leg 12 rotatably connected to its lower surface. Each of the four supporting legs 12 has a connecting rod 13 rotatably connected to the upper side of one side. Each of the four connecting rods 13 has a sliding block 14 rotatably connected to the upper side of one side. The four sliding blocks 14 are slidably connected inside the bases 1. Each of the four sliding blocks 14 has a pin 15 inserted into its upper surface. Each of the four pins 15 has a threaded bottom. Each of the two bases 1 has a storage hole 16 on both sides. Each of the four storage holes 16 has a threaded interior. Each of the four pins 15 is inserted into the storage hole 16, and the threaded bottom of the pins 15 has the same specifications as the threaded interior of the storage hole 16. Each of the four support legs 12 has a threaded sleeve 18 rotatably connected to its lower part. Each of the four threaded sleeves 18 has a knob 19 fixedly connected to its upper part. The outer walls of each of the four knobs 19 are located outside the support legs 12. Each of the four threaded sleeves 18 has a threaded rod 2 rotatably connected to its lower part. Each of the four threaded rods 2 has a foot 21 fixedly connected to its lower part. Each of the four foot 21 is slidably connected to the support legs 12. A level 11 is installed on one side of one base 1. Magnets 17 are fixedly connected to the lower part of one side of each of the four support legs 12 and to the lower part of each of the two bases 1. A placement plate 22 is fixedly connected to the upper part of each of the two bases 1. A music score placement block 27 is fixedly connected to one side of each of the two bases 1. A U-shaped groove 28 is opened on the upper part of each of the two music score placement blocks 27.

[0042] In this embodiment, the pins 15 above the four sliding blocks 14 are made of carbon steel and are rust-proof, making them sturdy and durable. The pins 15 can be inserted into the pin holes on the top of the base 1. When the support leg 12 is adjusted to a suitable angle, inserting the pins 15 can firmly fix the position of the sliding block 14, thereby stabilizing the support leg 12 and preventing the support leg 12 from changing its angle due to external force or vibration during use. This ensures that the guzheng stand can stably support the guzheng. The storage holes 16 on both sides of the two bases 1 have internal threads that are completely consistent with the thread specifications at the bottom of the pins 15. When the stand is stored, the pins 15 are pulled out from the pin holes and inserted into the storage holes 16. This not only achieves orderly storage of the pins 15 and avoids loss, but also makes the overall appearance of the stand more regular, reduces the storage space occupied, and makes it convenient for users to store and carry.

[0043] The threaded sleeves 18, which are rotatably connected to the four support legs 12 via deep groove ball bearings, reduce friction during rotation, making it easier for users to operate. The knob 19, which is integrally formed above the threaded sleeve 18, has anti-slip texture on its surface, increasing friction during operation and allowing users to adjust the rotation of the threaded sleeve 18 by rotating the knob 19. When the knob 19 is rotated, it drives the threaded rod 2, which is connected to the threaded sleeve 18 via threaded engagement, to move up and down, thereby realizing the height adjustment of the feet 21. The feet 21 are made of rubber, which has good anti-slip and shock absorption performance. When used on uneven ground, the height of the feet 21 can be adjusted to keep the bracket level and stable, preventing the guzheng from shaking due to uneven ground and affecting the performance. At the same time, the rubber feet 21 can effectively reduce the wear and tear of the bracket on the ground and protect the ground where it is placed.

[0044] A high-precision bubble level 11 installed on one side of a base 1 can intuitively and accurately display the horizontal status of the bracket. When setting up the guzheng bracket, the user can quickly adjust the angle of the support leg 12 and the height of the foot 21 by observing the level 11 to ensure that the bracket is in a horizontal position. This is crucial for guzheng performance. A horizontally placed bracket can ensure that the string tension is uniform, making the tone of the guzheng more accurate and stable, and improving the performance effect.

[0045] The wooden placement board 22, which is fixed to the top of the two bases 1 by bolts, has a finely polished surface. The wood material fits the bottom of the guzheng better, avoiding scratches and protecting the appearance and paint of the guzheng. The placement board 22 provides a stable and safe platform for the guzheng, ensuring that the guzheng is placed firmly on the stand. At the same time, the texture of the wood material matches the classical style of the guzheng, enhancing the overall aesthetics. The U-shaped groove 28 is used for placing the sheet music.

[0046] Working principle: Take out the foldable portable guzheng stand from the storage area and check each component for damage, including the base 1, support leg 12, connecting rod 13, sliding block 14, pin 15, threaded sleeve 18, knob 19, threaded rod 2, foot 21, level 11, magnet 17, and placement plate 22. Pay special attention to whether the hinge 25 can rotate flexibly and whether the connection between the limit rod 23 and the plectrum 24 is secure.

[0047] Hold the two bases 1 and unfold them to the desired angle, generally 180°, by rotating the hinges 25 to ensure the support is placed stably. Be careful not to use excessive force during unfolding to avoid damaging the hinges 25. Then, rotate the four support legs 12 from under the bases 1 one by one. Since the support legs 12 can rotate 360° via hinges, the angle of the support legs 12 can be adjusted according to the actual ground conditions, such as whether the ground is sloped or flat. When adjusting the angle of the support legs 12, the connecting rod 13 will drive the sliding block 14 to slide within the groove inside the base 1 until the support legs 12 reach the appropriate support angle.

[0048] After the support leg 12 is adjusted to the appropriate angle, locate the pin 15 located above the sliding block 14 and insert the pin 15 into the corresponding pin hole above the base 1. Since the pin 15 is made of carbon steel and is rust-proofed, it can firmly fix the position of the sliding block 14 after insertion, thereby stabilizing the support leg 12 and preventing it from accidentally changing its angle due to external force or vibration during subsequent use.

[0049] Observe the high-precision bubble level 11 installed on one side of the base 1. If the level 11 indicates that the support is not level, it can be adjusted by adjusting the height of the feet 21. Rotate the knob 19 inside the lower part of the support leg 12. The knob 19 is integrally formed with the threaded sleeve 18. Rotating the knob 19 will drive the threaded sleeve 18 to rotate. Since the threaded rod 2 and the threaded sleeve 18 are connected by a threaded engagement, and the feet 21 are fixedly connected to the bottom of the threaded rod 2, the rotation of the threaded sleeve 18 will cause the threaded rod 2 to move the feet 21 up and down. According to the indication of the level 11, fine-tune the height of the feet 21 on the four support legs 12 until the level 11 indicates that the support is level. This step is crucial for ensuring that the string tension is even and that an accurate and stable tone is produced when playing the guzheng.

[0050] After ensuring the support is level and stable, carefully place the guzheng on the wooden placement board 22, which is bolted together above the two bases 1. The surface of the wooden placement board 22 is finely sanded to better fit the bottom of the guzheng, preventing scratches and protecting its appearance and finish, while providing a stable and safe platform for placement.

[0051] After the performance, carefully remove the guzheng from the placement board 22.

[0052] Pull out the pin 15 and remove it from the pin hole on the top of the base 1. Then insert the pin 15 into the storage holes 16 on both sides of the base 1. Since the thread inside the storage hole 16 is exactly the same as the thread at the bottom of the pin 15, the pin 15 can be stored in an orderly manner after insertion, avoiding loss, and making the overall appearance of the bracket more neat.

[0053] The four support legs 12 are rotated and retracted to the bottom of the base 1 in sequence. At this time, the connecting rod 13 drives the sliding block 14 to slide in the reverse direction in the sliding groove inside the base 1.

[0054] Rotate hinge 25 to fold and attach the two bases 1 together, completing the storage of the stand for easy storage and carrying.

[0055] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
