Description

Technical Field

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

[0002] Music stands are essential tools for musicians, conductors, and students during practice. Their main function is to hold music scores at a height and angle that is easy for the user to view. With the increasing frequency of performances and rehearsals, portable music stands that can be easily disassembled, folded, and carried have become widely used due to their flexibility.

[0003] In the daily use of portable music stands, users have two core operational needs: first, to adjust the angle of the music stand to accommodate different sitting, standing, or lighting conditions; and second, to quickly assemble and disassemble the music stand to meet the needs of portable storage.

[0004] However, existing portable music stands generally fall short in meeting these requirements. Firstly, regarding angle adjustment, most music stands rely on bolts or knobs for fastening. Users must loosen the fasteners with considerable effort before adjusting the angle and then tighten them again. This method, which relies entirely on friction, is not only cumbersome and inefficient, but more seriously, its reliability decreases with repeated use. The friction surfaces or threads gradually wear down during repeated tightening and loosening, resulting in insufficient locking force. When the music stand bears thick sheet music or experiences slight impacts, it is prone to tilting or slipping, affecting the continuity and stability of the performance.

[0005] Secondly, regarding the assembly and disassembly structure, in order to achieve portability, existing music stands typically use simple plug-in connections or bolt fixation for their columns and connectors. While simple plug-in connections are quick, the large gaps between the connections result in a loose, wobbly, and unstable overall music stand structure. Bolt fixation, while ensuring a certain level of stability, makes each assembly and disassembly process extremely time-consuming, contradicting the principles of "portability" and "speed," and also carries the risk of losing parts. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a portable music stand connector for musical instruments, which aims to improve the problems of inconvenient operation and unreliable fixation after long-term use due to the friction locking method used for angle adjustment, as well as the cumbersome disassembly and assembly or unstable connection caused by the disassembly and assembly structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable music stand connector for musical instruments, comprising: a support rod, a rotating tube, a connecting tube, and a column; and a rotating mechanism disposed between the support rod and the rotating tube, and a snap-fit ​​mechanism disposed between the connecting tube and the column.

[0008] The rotating mechanism includes a second gear disk fixed inside the rotating tube, a first gear disk slidably disposed therein along the axial direction of the support rod, and a first spring for pushing the first gear disk toward the second gear disk.

[0009] Furthermore, the snap-fit ​​mechanism includes a through hole in the wall of the connecting pipe, a steel ball housed in the through hole, an annular groove in the outer wall of the column that mates with the steel ball, a slide tube that can be slidably fitted onto the outside of the connecting pipe along its axial direction, and a second spring for applying axial elastic force to the slide tube; the inner wall of the slide tube has a locking surface for selectively squeezing the steel ball and an exit groove for releasing the steel ball.

[0010] Preferably, the rotating mechanism further includes a slide rod and a pressure plate, the pressure plate being connected to the slide rod, and the slide rod being linked to the first gear disc to drive the first gear disc to slide on the support rod and compress the first spring.

[0011] Preferably, the rotating tube is a hollow rod, and the sliding rod passes through the inside of the rotating tube; the pressure plate is located outside the rotating tube and is connected to the sliding rod.

[0012] Preferably, the first gear disc and the support rod are fitted by a key or a non-circular cross section to achieve circumferential fixation and axial sliding.

[0013] Preferably, the outer wall of the support rod is provided with a sliding groove extending along its axial direction, and the inner wall of the rotating tube is fixed with a slip ring that slides in cooperation with the sliding groove.

[0014] Preferably, the snap-fit ​​mechanism further includes a fixing block fixed to the outer wall of the connecting pipe, and the second spring is sleeved on the connecting pipe, with its two ends abutting against the fixing block and the sliding pipe respectively.

[0015] Preferably, a connecting rod is also connected to the rotating tube.

[0016] Preferably, the inner wall of the slide tube has a locking surface and an exit groove, wherein the locking surface is a columnar surface and the exit groove is a groove formed on the columnar surface.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the angle is locked by the meshing of the toothed discs. Compared with the traditional structure that relies on friction to lock, it is a mechanical positive locking with a large contact area and uniform force. It completely solves the problem of angle loosening and music stand "nodding" caused by wear or vibration, and ensures the long-term stability and reliability of the music stand angle.

[0019] 2. In this utility model, a bead-lock type snap-fit ​​mechanism is used to achieve quick assembly and disassembly of the music stand column and connector. During assembly, simply inserting the column will automatically lock it in place. During disassembly, it can be unlocked by sliding the slide tube with one hand. The entire process requires no tools, greatly simplifying the operation and improving the portability and storage convenience of the music stand. It is especially suitable for performance occasions that require frequent movement and setup. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 5 This utility model provides a portable music stand connector for musical instruments, which aims to solve the problems of unstable fixed angle and inconvenient disassembly and assembly in the prior art.

[0029] like Figure 1 As shown, the portable music stand connector for musical instruments includes a support rod 1, a rotating tube 3, a connecting tube 5, and a column 7. The rotating tube 3 is rotatably sleeved on the outside of the support rod 1, the connecting tube 5 is fixedly connected to the lower end of the support rod 1, and the column 7 is detachably inserted into the inside of the connecting tube 5.

[0030] Specifically, such as Figures 1 to 4 As shown, the portable music stand connector for musical instruments also includes a rotating mechanism 2 disposed between the support rod 1 and the rotating tube 3. The rotating mechanism 2 includes a second gear 203 fixed inside the rotating tube 3, a first gear 202 axially slidably disposed inside the support rod 1, and a first spring 201 sleeved on the support rod 1. The tooth surfaces of the first gear 202 and the second gear 203 are arranged facing each other. One end of the first spring 201 abuts against the first gear 202 to provide elastic force for meshing the first gear 202 and the second gear 203. A connecting rod 4 is fixedly connected to the rotating tube 3; the rotating mechanism 2 also includes a pressure plate 205 and a slide rod 204. The rotating tube 3 has a hollow structure. The slide rod 204 passes through the inside of the rotating tube 3. The pressure plate 205 is set outside the rotating tube 3 and fixedly connected to the slide rod 204. The slide rod 204 is connected to the first gear plate 202 for transmission, so as to drive the first gear plate 202 to slide axially and compress the first spring 201. The outer wall of the support rod 1 is provided with a sliding groove 207 extending along its axial direction. The inner wall of the rotating tube 3 is fixed with a slip ring 206 that slides with the sliding groove 207.

[0031] like Figure 1 and Figure 5As shown, the portable music stand connector for musical instruments also includes a locking mechanism 6 disposed between the connecting tube 5 and the column 7. The locking mechanism 6 includes a through hole 605 opened in the wall of the connecting tube 5, a steel ball 606 movably accommodated in the through hole 605, an annular groove 607 opened in the outer wall of the column 7 that cooperates with the steel ball 606, a slide tube 603 axially slidably sleeved on the outside of the connecting tube 5, and a second spring 602 for applying axial elastic force to the slide tube 603. The inner wall of the slide tube 603 has a locking surface for pressing the steel ball 606 and an exit groove 604 for releasing the steel ball 606. The locking mechanism 6 also includes a fixing block 601 fixedly connected to the outer wall of the connecting tube 5, and the second spring 602 is sleeved on the connecting tube 5, with its two ends abutting against the fixing block 601 and the slide tube 603 respectively.

[0032] In a preferred embodiment, to achieve stable axial sliding of the first gear disc 202 on the support rod 1 without circumferential rotation, the inner hole of the first gear disc 202 and the outer shape of the support rod 1 are connected by a key or a non-circumferential cross-section to form a connection that is circumferentially fixed and axially sliding. To ensure the smoothness of the rotation process of the rotating tube 3, a sliding groove 207 extending axially is opened on the outer wall of the support rod 1, and a slip ring 206 is fixed on the inner wall of the rotating tube 3, the slip ring 206 being slidably embedded in the sliding groove 207. To drive the first gear disc 202, the support rod 1 is configured as a hollow rod body, the sliding rod 204 is movably inserted inside the support rod 1, and the pressure plate 205 is located outside the support rod 1 and is connected to the sliding rod 204 through an opening in the side wall of the support rod 1. 4. Fixed connection; To achieve automatic reset of the slide tube 603, the locking mechanism 6 includes a fixing block 601 fixed to the outer wall of the connecting tube 5, and a second spring 602 sleeved on the connecting tube 5. The two ends of the second spring 602 abut against the fixing block 601 and the slide tube 603 respectively. The inner wall surface of the slide tube 603 is composed of a columnar locking surface and an exit groove 604 opened on the locking surface. Under the action of the elastic force of the second spring 602, the locking surface squeezes the steel ball 606 into the annular groove 607. When the exit groove 604 slides to the position of the steel ball 606 under the action of external force, it accommodates the steel ball 606 to exit the annular groove 607. A connecting rod 4 is also fixedly connected to the rotating tube 3. The connecting rod 4 is used to install the music score holder.

[0033] Working principle: When the portable music stand connector for musical instruments needs to adjust the angle of the music stand connected by the connecting rod 4, the pressure plates 205 on both sides are pressed down. The pressure plates 205 push the first toothed disc 202 to slide along the axis of the support rod 1 through the slide rod 204. The first toothed disc 202 simultaneously squeezes the first spring 201, causing the tooth surface of the first toothed disc 202 to disengage from the tooth surface of the second toothed disc 203 fixed inside the rotating tube 3. At this time, the rotating tube 3 can rotate freely around the support rod 1. When rotating, the slip ring 206 on the rotating tube 3 slides in the slide groove 207 set on the support rod 1, thereby driving the connecting rod 4 to adjust the angle. After adjusting to the appropriate angle, the pressure plates 205 are released, the squeezed first spring 201 rebounds, pushes the first toothed disc 202 to move towards the second toothed disc 203 and re-engages, thereby locking the angle of the rotating tube 3.

[0034] When the music stand needs to be disassembled, pinch the slide tube 603 of the locking mechanism 6 and slide it upward along the connecting tube 5. During the sliding process, the slide tube 603 compresses the second spring 602 between it and the fixing block 601. When the exit groove 604 on the slide tube 603 and the steel ball 606 in the through hole 605 on the side wall of the connecting tube 5 are at the same horizontal position, the steel ball 606 is no longer squeezed by the locking surface of the inner wall of the slide tube 603 and can exit from the annular groove 607 at the top of the column 7. At this time, the column 7 can be pulled out from the connecting tube 5. When it is necessary to assemble and fix the column 7, insert the column 7 into the connecting tube 5. After releasing the slide tube 603, the second spring 602 rebounds and pushes the slide tube 603 to reset. The locking surface of the inner wall of the slide tube 603 re-squeezes the steel ball 606, so that the steel ball 606 is stuck into the annular groove 607 of the column 7, thereby realizing the stable locking between the column 7 and the connecting tube 5.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
