Description

Technical Field

[0001] This utility model relates to the field of musical instrument accessories technology, and in particular to a temporary violin stand for musical instruments. Background Technology

[0002] As a stringed instrument with a precise construction and high value, the violin requires a stable and reliable device for temporary placement during performance breaks, practice pauses, or daily storage to prevent damage from collisions, scratches, or drops caused by careless placement. Therefore, temporary violin stands are widely used as an important auxiliary accessory.

[0003] Most violin stands on the market today are foldable tripods or A-frames. They form a stable floor support structure by unfolding the legs at a certain angle, thus supporting the violin. This design meets basic placement needs to a certain extent.

[0004] However, in order to accommodate violins of different sizes or to ensure stable placement in various usage scenarios and spaces, the opening angle of the support legs of such stands usually needs to be adjusted. Existing technologies often employ relatively simple methods for adjusting and fixing the opening angle, such as relying on friction between components for locking, or using simple pinhole structures for segmented positioning.

[0005] Friction-based locking structures are prone to wear and tear during use, leading to a decrease in locking force. After prolonged heavy loads, there is a risk of the platform tipping over due to the slow sliding of the support legs. The simple pin-hole positioning method has limited adjustable levels, making precise width adjustments impossible, and usually requires both hands for adjustment, which is inconvenient. These structural deficiencies result in defects in the ease of adjustment and structural stability of existing platforms after locking, directly affecting the overall safety and reliability of the platform and posing a potential safety hazard to valuable violins.

[0006] Therefore, this utility model proposes a temporary violin stand to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the temporary violin placement platform for musical instruments, such as inconvenient adjustment of the opening and closing angle of the support legs, unstable locking structure, and safety hazards, this utility model aims to provide a temporary violin placement platform for musical instruments with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a temporary violin stand for musical instruments, including a support frame, a clamping mechanism fixedly connected to the top of the support frame, and an adjustment mechanism rotatably connected to the bottom of the support frame.

[0009] The clamping mechanism includes a clamping claw with a protective pad fixedly connected to the inner clamping surface, a sliding column fixedly connected to the clamping claw at one end, a support cylinder fixedly connected to the support frame, and a first spring surrounding the outer periphery of the sliding column. The sliding column is slidably fitted inside the support cylinder, and the two ends of the first spring act on the sliding column and the support cylinder, respectively.

[0010] The adjustment mechanism includes a support leg with an anti-slip pad fixedly connected to its bottom end, a rotating shaft for rotating the support leg to the support frame, a second telescopic cylinder fixedly connected to the support frame and having several limiting grooves, a second telescopic column fixedly connected to the support leg and slidably fitted inside the second telescopic cylinder, a fixed ball movably disposed in the second telescopic column and capable of being inserted into the limiting groove, and a second spring disposed inside the second telescopic column and pushing the fixed ball into the limiting groove. This structure enables the locking of the spacing between the support legs in different increments.

[0011] Preferably, the clamping mechanism further includes an elastic limiting block and a fixing block, both of which are fixedly connected to the upper part of the support frame and located on the side of the clamping claw.

[0012] Preferably, the adjustment mechanism further includes a first telescopic cylinder and a first telescopic column. The first telescopic cylinder is fixedly connected to the middle of the support frame, the first telescopic column is slidably fitted inside the first telescopic cylinder, and the lower end of the first telescopic column is fixedly connected to a second telescopic column.

[0013] Preferably, the adjustment mechanism further includes a support rod, which is fixedly connected to the top of the first telescopic column.

[0014] Preferably, a rotating block is also provided inside the fixed ball, one end of the second spring acts on the rotating block, and the other end acts on the second telescopic column. The connection is used to push the fixed ball into the limiting groove through the rotating block.

[0015] Preferably, the limiting grooves are arranged at equal or unequal intervals along the length direction of the second telescopic cylinder.

[0016] Preferably, the number of gripping claws is two, and they are arranged symmetrically.

[0017] Preferably, the support cylinder is longitudinally disposed inside the support frame.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model solves the problems of cumbersome operation, difficult control of clamping force and poor adaptability of existing clamping structures by setting a sliding column and a support cylinder with sliding fit, and using the rebound force of the first spring to drive the clamping claw connected to the sliding column for clamping.

[0020] 2. This utility model solves the problems of complex structure and unreliable locking of the bracket width adjustment mechanism in the prior art by setting a second telescopic column that can slide inside the second telescopic cylinder and using a second spring to push the fixed ball into the limiting groove on the second telescopic cylinder.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 4 This utility model provides a temporary violin stand for musical instruments, which aims to solve the problems of unreliable clamping and fixing of existing violin supports and lack of adaptability, as well as the complex width adjustment structure and unstable positioning.

[0031] like Figure 1 and Figure 2 As shown, the temporary violin stand for musical instruments in this embodiment uses a support frame 1 as the central load-bearing structure. The upper part of the support frame 1 is integrated with a clamping mechanism 2 for clamping and fixing the violin, and the lower part is equipped with an adjustment mechanism 3 for supporting and adjusting the width.

[0032] Specifically, the clamping mechanism 2 is constructed as follows: two mutually symmetrical support cylinders 206 are longitudinally arranged inside the support frame 1, and both support cylinders 206 are fixedly connected to the support frame 1; each support cylinder 206 has a sliding column 205 slidably fitted inside, and the outer end of the sliding column 205 is fixedly connected to a clamping claw 203 for directly contacting and clamping the piano body;

[0033] To protect the surface of the instrument, a protective pad 204 is fixedly connected to the inner clamping surface of each clamping claw 203. A first spring 207 is arranged around the outer periphery of the sliding column 205. The two ends of the first spring 207 act on the flange on the sliding column 205 and the end wall of the support cylinder 206, respectively, thereby providing a continuous inward rebound force to the sliding column 205 and the clamping claw 203. In addition, in order to place the bow, an elastic limiting block 201 and a fixing block 202 are fixedly connected to the upper part of the support frame 1 and located on the side of the clamping claw 203.

[0034] The adjustment mechanism 3 is a linkage structure with synchronous telescopic and segmented locking, and its construction is as follows: At the bottom of the support frame 1, two outwardly opening support legs 302 are rotatably connected via a pivot 301. Each support leg 302 has an anti-slip pad 303 fixedly connected to its bottom end to increase stability. To achieve synchronous width adjustment, the adjustment mechanism 3 has two sets of telescopic components. The first set of telescopic components includes a first telescopic cylinder 305 fixedly connected to the middle of the support frame 1, and a first telescopic column 306 slidably fitted inside the first telescopic cylinder 305. The support rod 304 for placing the bottom of the violin is fixedly connected to the top of the first telescopic column 306. The second set of telescopic components includes a second telescopic cylinder 308 fixedly connected to the support frame 1, and a second telescopic column 307 slidably fitted inside the second telescopic cylinder 308. The outer end of the second telescopic column 307 is fixedly connected to the support leg 302. Meanwhile, the lower end of the first telescopic column 306... The second telescopic column 307 is fixedly connected to the second telescopic column 308, thereby forming a synchronous linkage relationship between the opening and closing angle of the support leg 302 and the spacing of the support rod 304. In order to lock the adjustable width, a number of limiting grooves 309 are provided on the outer wall of the second telescopic cylinder 308 at equal or unequal intervals along its length. Inside the second telescopic column 307, a locking module consisting of a fixed ball 310, a rotating block 311, and a second spring 312 is provided. The fixed ball 310 is movably disposed in the side wall opening of the second telescopic column 307 and can be inserted into the external limiting groove 309. The second spring 312 is disposed inside the second telescopic column 307. One end of the spring acts on the rotating block 311 inside the fixed ball 310, and the other end acts on the second telescopic column 307. Through continuous elastic force, the fixed ball 310 is pushed through the rotating block 311 to engage with the limiting groove 309, thereby realizing the locking of the opening and closing angle of the support leg 302 in stages.

[0035] The clamping mechanism 2 and the adjustment mechanism 3 are connected by the support frame 1 to form an organic whole in terms of structure and function. The clamping mechanism 2 achieves adaptive clamping of violin bodies of different thicknesses through the spring reset structure, while the adjustment mechanism 3 achieves convenient adjustment and reliable fixation of violins of different specifications through the linkage structure of synchronous extension and locking.

[0036] Please refer to the following carefully. Figure 3 and Figure 4In use, the clamping mechanism 2 operates as follows: the user pulls the two clamping claws 203 outwards. This pulling force is transmitted to the sliding column 205 through a fixed connection, causing the sliding column 205 to slide outwards inside the support cylinder 206. This process stretches the first spring 207 surrounding the outer periphery of the sliding column 205. When the distance between the two clamping claws 203 is sufficient to accommodate the violin body, the clamping claws 203 are released. The stretched first spring 207 contracts and rebounds, generating an inward pulling force on the sliding column 205, which in turn drives the clamping claws 203 to move inwards until the inner protective pad 204 adheres to the side wall of the violin body and applies a continuous clamping force, thereby completing the stable fixation of the violin. The entire process does not require manual adjustment of the precise size of the clamping opening, and the bow can be placed between the elastic limiting block 201 and the fixing block 202.

[0037] The operation of the adjustment mechanism 3 is as follows: the user squeezes the fixed ball 310, which is movably mounted on the second telescopic column 307, inward. The pressure is transmitted through the rotating block 311 inside the fixed ball 310 and compresses the second spring 312 inside the second telescopic column 307, causing the fixed ball 310 to disengage from the limiting groove 309 of the second telescopic cylinder 308 and release the locking state. At this time, the user can freely pull the support leg 302 to rotate around the pivot 301 to adjust the unfolded width of the placement platform. During the rotation of the support leg 302, it drives the second telescopic column 307 to slide inside the second telescopic cylinder 308, and... Since the lower end of the first telescopic column 306 is fixedly connected to the second telescopic column 307, the first telescopic column 306 will also slide synchronously inside the first telescopic cylinder 305, thereby causing the spacing between the support rods 304 fixedly connected to the top of the first telescopic column 306 to change synchronously. When the appropriate width is adjusted, the fixed ball 310 is released, the compressed second spring 312 rebounds, and its elastic force pushes the rotating block 311, thereby pushing the fixed ball 310 into the limit groove 309 aligned with it, completing the reliable locking of the current width. The anti-slip pad 303 at the bottom ensures the stability of the bracket after adjustment.

[0038] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0039] As a preferred embodiment, in order to enhance the reliability and stability of the violin body clamping, the clamping mechanism 2 preferably has two clamping claws 203, and these two clamping claws 203 are symmetrically arranged along the support frame 1. This can ensure that a balanced and stable clamping force is formed on the violin bones, thereby preventing the instrument from shaking or accidentally falling off.

[0040] As another preferred embodiment, in order to more effectively use the clamping mechanism 2 to fix the bow, the clamping mechanism 2 also includes an elastic limiting block 201 and a fixing block 202. The elastic limiting block 201 and the fixing block 202 are both fixedly connected to the upper part of the support frame 1 and located on the side of the clamping claw 203. This design utilizes the flexibility of the elastic limiting block 201 to accommodate and fasten the bow, and the fixing block 202 provides reliable support and positioning.

[0041] As another preferred embodiment, in order to realize the linkage adjustment between the opening and closing of the support leg 302 and the lifting and lowering of the support rod 304, the adjustment mechanism 3 also includes a first telescopic cylinder 305 and a first telescopic column 306. The first telescopic cylinder 305 is fixedly connected to the middle of the support frame 1, and the first telescopic column 306 is slidably fitted inside the first telescopic cylinder 305. The lower end of the first telescopic column 306 is fixedly connected to the second telescopic column 307. This connection method ensures that when the angle of the support leg 302 changes, the spacing of the support rod 304 is adjusted synchronously, without the need for secondary manual adjustment.

[0042] As another preferred embodiment, in order to provide a reliable instrument placement platform after the telescopic adjustment is synchronized, the adjustment mechanism 3 also includes at least one pair of support rods 304, which are fixedly connected to the top of the first telescopic column 306 and serve as components that directly support the bottom of the violin.

[0043] As another preferred embodiment, in order to achieve a stable push inside the locking structure, a rotating block 311 is provided inside the fixed ball 310. One end of the second spring 312 acts on the rotating block 311, and the other end acts on the inner wall of the second telescopic column 307. The elastic force of the second spring 312 pushes the fixed ball 310 through the rotating block 311, so that it is more accurately and stably locked into the limiting groove 309, providing a reliable locking force.

[0044] As another preferred embodiment, in order to meet the adjustment accuracy requirements of different specifications or different placement requirements, a number of limiting grooves 309 are provided on the second telescopic cylinder 308. These limiting grooves 309 can be arranged at equal intervals or at unequal intervals along the length direction of the second telescopic cylinder 308, so that the locking of the support leg 302 can correspond to a variety of preset angles or widths.

[0045] As another preferred embodiment, in order to ensure the stability of the movement of the components of the clamping mechanism 2, the support cylinder 206 is longitudinally arranged inside the support frame 1. This embedded installation method can provide more stable guiding support for the sliding column 205 and protect its sliding surface from external contamination.

[0046] The working principle of this utility model of a temporary violin stand is as follows:

[0047] When the violin needs to be placed, the user first pulls the clamping claw 203 outward. Through its fixed connection with the sliding column 205, the clamping claw 203 drives the sliding column 205 to slide outward inside the support cylinder 206. This action stretches the first spring 207 sleeved on the outer periphery of the sliding column 205 and stores elastic energy. When the distance between the clamping claws 203 is sufficient to accommodate the violin body, the violin bones are placed on the two support rods 304 and the clamping claws 203 are released. The first spring 207 then rebounds and contracts, pulling the clamping claws 203 inward through the sliding column 205 until the protective pad 204 on it adheres to the side wall of the violin body and applies a continuous clamping force, thereby achieving adaptive and stable fixation of the violin body. The bow can be placed between the elastic limiting block 201 and the fixing block 202 for limiting.

[0048] When the width of the platform needs to be adjusted according to the violin's specifications, the user presses the fixed ball 310 on the second telescopic column 307 inward. The fixed ball 310 moves inward and disengages from the limiting groove 309 on the second telescopic cylinder 308, releasing the locked state. At this time, the user can move the support leg 302 outward or inward. The support leg 302 rotates around the pivot 301 and, through its fixed connection with the second telescopic column 307, drives the second telescopic column 307 to slide inside the second telescopic cylinder 308. Since the lower end of the first telescopic column 306 is fixedly connected to the second telescopic column 307, the first telescopic column 306 also slides synchronously inside the first telescopic cylinder 305, thereby causing the support rod 304 fixed at its top to change the spacing synchronously. After adjusting to the appropriate width, the user releases the fixed ball 310, and the second spring 312 inside it rebounds. Through the rotating block 311, the fixed ball 310 is pushed outward and locked into the aligned limiting groove 309, completing the locking of the current adjustment width.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
