Description

Technical Field

[0001] The invention relates to the technical field of musical instrument frames, in particular to a support rod for preventing a musical instrument frame from tilting and a musical instrument frame. Background Art

[0002] A musical instrument stand is a device for vertically placing musical instruments (such as guitars and violins). The present invention is directed to a widely used musical instrument stand, which has a clamping structure on the top to fix the neck of the musical instrument. The musical instrument stand also has a supporting upright pole, the length of which is generally longer than the length of the musical instrument. A clamping mechanism is fixed at one end of the supporting upright pole, and the other end is fixed on a base. The base of the musical instrument stand is used to support the supporting upright pole, the clamping mechanism and the fixed musical instrument. The bases of many musical instrument stands are designed to be foldable and composed of a plurality of supporting poles, so as to reduce the volume and weight during transportation and storage.

[0003] There is an obvious problem with this type of stand, which is that the instrument has only one fixed point on the stand. The instrument may swing under the action of external force. When the swing amplitude of the instrument is too large, causing the center of gravity to exceed the support range of the base, it may fall over as a whole. This situation is very likely to cause damage to the instrument. In order to achieve the best acoustic performance, most musical instruments are more likely to suffer serious damage in this process of tipping, from the selected materials to the overall structure and manufacturing process. For example, for a guitar, it is easy to cause the neck and body of the guitar to break.

[0004] In order to solve this problem, some manufacturers have considered some improvement plans. For example, they can increase the weight of the base to lower the overall center of gravity. However, an overly heavy base makes it difficult to transport and carry the product. Some manufacturers have also tried to lengthen the support rod of the base, but the problem brought about by this is that the overall size of the product becomes larger. At the same time, many piano stands that are already in use also need a solution to this problem. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned prior art, the present invention provides a support rod and a music frame for preventing a music frame from tilting. The support rod can be fixed on a base of the music frame, in particular, on a bottom rod of the base. By adjusting the position of the support rod on the support rod, the actual area supported by the base of the music frame can be adjusted, thereby ensuring that the musical instrument can swing within a larger range without tipping over due to the shift of the center of gravity.

[0049] Example 1

[0050] like Figure 1-2 The embodiment disclosed in the figure is a support rod for preventing a musical instrument frame from tilting. The support rod mainly comprises a connecting portion 1 and a supporting portion 2. A connecting mechanism is provided at one end of the connecting portion 1 to be detachably connected to the bottom rod 16 of the musical instrument frame. One end of the supporting portion 2 is hinged to the other end of the connecting portion 1, and the other end of the supporting portion 2 is freely extended. The supporting portion 2 has a folded state and an opened state:

[0051] When the support part 2 is in the folded state, the support part 2 is parallel to the piano frame bottom rod 16, that is, Figure 3 As shown;

[0052] When the support part 2 is in the open state, the support part 2 and the piano frame bottom rod 16 form a human-shaped frame to expand the support area of ​​the piano frame bottom rod 16, that is, Figure 4 shown.

[0053] In the specific application process, the support rod can be fixed on the bottom rod 16 of the piano frame, and the actual area supported by the piano frame base can be adjusted by adjusting the position of the support rod on the bottom rod 16, so as to ensure that the instrument can swing in a larger range without tipping over due to the shift of the center of gravity. Figure 5 , which shows the difference in the supporting area when a piano stand is equipped with multiple supporting rods 17. The inner dotted circle indicates the original supporting area of ​​the piano stand base. When the overall center of gravity exceeds this circle due to the swing of the instrument, it may overturn. Figure 5 The dotted circle in the middle outside represents the new support area of ​​the piano stand base after the support rod 17 is added. It can be clearly seen that the entire support area has been greatly expanded. Therefore, the phenomenon of overall overturning can be prevented as much as possible. At the same time, since the support part 2 on the support rod 17 can be folded, when it is needed to play a supporting role, the support part 2 can be turned to an open state. When support is not needed, such as during transportation and storage, the support part 2 can be turned to a folded state to reduce the occupied space, thereby achieving a protective effect with minimal increase in weight and volume.

[0054] In the specific implementation process, two parallel clamping plates 101 are arranged on one end of the connecting part 1 connected to the supporting part 2, and the end of the supporting part 2 is clamped between the two clamping plates 101 and rotates with the two clamping plates 101 through a rotating shaft 3 to achieve hinged connection.

[0055] In this embodiment, a damping structure is provided between the support portion 2 and the connection portion 1, so that a certain external force is required when the support rod is switched between the open state and the folded state, thereby keeping the support portion 2 in the folded state or the open state. In the specific implementation process, the damping structure includes a spring 4, a first washer 5, a second washer 6, and a shoulder 201 provided on the support portion 2; the spring 4, the first washer 5, and the second washer 6 are all sleeved on the support portion 2, and one end of the spring 4 abuts on the shoulder 201 through the first washer 5, and the other end abuts on the end of the connection portion 1 through the second washer 6, and the spring 4 is in a compressed state at this time. That is, the spring 4 is compressed between the end of the connection portion 1 and the shoulder 201 of the support portion 2. The function of the spring 4 is to ensure that a certain force is required when rotating the support portion 2, so as to ensure that the support portion 2 remains in the open state. At the same time, the spring 4 can also ensure that when the rod body is folded, a certain force is also required to rotate to the open state, so that the folded state can be maintained. It should be noted that in the specific implementation, it is also possible to choose not to set the damping structure, or to set the damping structure to other structural forms.

[0056] refer to Figure 6 , is the first implementation of the connection mechanism in this embodiment. In this implementation, the connection mechanism includes a snap ring 102 provided at the end of the connection part 1, and the snap ring 102 has an opening, and the opening is located on the length extension line of the connection part 1. The snap ring 102 is made of metal material. Due to the existence of the opening, the snap ring 102 has a certain elastic deformation ability, and then when the diameter of the bottom rod 16 of the music frame is larger than the inner diameter of the snap ring 102, the snap ring 102 can be clamped on the bottom plate of the music frame. Preferably, a flared structure 103 extending outward can be provided at the positions corresponding to the two ends of the opening on the snap ring 102, so that the snap ring 102 can be more conveniently clamped into the bottom rod 16 of the music frame.

[0057] refer to Figure 7 , which is the second implementation of the connection mechanism in this embodiment. In this implementation, the connection mechanism includes a snap ring 102 provided at the end of the connection part 1, and the snap ring 102 has an opening, and the opening is located on the length extension line of the connection part 1. The snap ring 102 is made of metal material. Due to the existence of the opening, the snap ring 102 has a certain elastic deformation ability, and then when the diameter of the bottom rod 16 of the music frame is larger than the inner diameter of the snap ring 102, the snap ring 102 can be clamped on the bottom plate of the music frame. The connection mechanism also includes a locking structure provided on the snap ring 102, which is used to compress the opening, so that the snap ring 102 tightly wraps the bottom rod 16 of the music frame, and then even if the inner diameter of the snap ring 102 is larger than the diameter of the bottom rod 16 of the music frame, the snap ring 102 can be fixed on the bottom rod 16 of the music frame through the locking structure.

[0058] More specifically, in the second embodiment of the above-mentioned connection mechanism, locking plates 104 extending outward are provided at positions corresponding to both ends of the opening on the snap ring 102, and locking holes are provided on the two locking plates 104. The locking structure includes a screw rod 7, a nut 8, a third washer 9 and a torsion piece 10. The nut 8 abuts against one of the locking plates 104, and the torsion piece 10 abuts against the other locking plate 104 through the third washer 9. One end of the screw rod 7 is connected to the torsion piece 10, and the other end passes through the locking holes of the two locking plates 104 in sequence and is threadedly connected to the nut 8. The third washer 9 is sleeved on the screw rod 7. Among them, a cross bar 11 is inserted into the screw rod 7, and the torsion piece 10 is fixedly connected to the screw rod 7 through the cross bar 11. By twisting the torsion piece 10, the screw rod 7 and the nut 8 are threadedly fixed, and the two locking plates 104 are pressed close to each other, thereby locking the snap ring 102 on the bottom rod 16 of the piano frame.

[0059] Preferably, in both embodiments of the above-mentioned connection mechanism, an anti-slip cover 12 can be provided on the inner wall of the clamp ring 102. The anti-slip cover 12 is made of a material with elasticity and relatively large surface friction resistance, such as rubber or silicone. When the clamp ring 102 is deformed, the anti-slip cover 12 is first squeezed, and at the same time, the anti-slip cover 12 and the bottom support rod of the piano frame are tightly connected.

[0060] It should be noted that, in specific implementations, the connection mechanism is not limited to the above two implementations, and other connection methods, such as magnetic adsorption, threaded connection, etc., may also be used.

[0061] In this embodiment, the support portion 2 is a telescopic rod structure with adjustable length. Figure 2The support part 2 includes a first rod body 202 and a second rod body 203. Both the first rod body 202 and the second rod body 203 are hollow tubes, and the material can be a hard material such as metal or plastic. The head end of the first rod body 202 is hinged with the connecting part 1, and the tail end is provided with a telescopic hole along the axial direction, that is, the damping structure is arranged on the first rod body 202. The tail end of the first rod body 202 is fixedly arranged on the extension connecting member 204, and the extension connecting member 204 is provided with a connecting hole 205 connected with the telescopic hole, and the aperture of the connecting hole 205 is elastically variable; the head end of the second rod body 203 passes through the connecting hole 205 and then extends into the telescopic hole, and the second rod body 203 is sleeved with an adjusting knob 206, which is threadedly connected to the extension connecting member 204 and compresses the connecting hole 205 to connect and fix the first rod body 202 and the second rod body 203. When the adjusting knob 206 is rotated to a loose position, the second rod body 203 can slide relatively inside the first rod body 202. When the second rod body 203 slides to a desired position, the adjusting knob 206 can be rotated in the reverse direction until the connecting hole 205 of the extending connecting member 204 is deformed, further locking the second rod body 203 until it can no longer move radially relative to the first rod body 202, thereby completing the function of adjusting the length. Figure 8-9 That is, different states of extension and retraction of the support portion 2 are respectively shown.

[0062] Optionally, a pin 13 is provided at the tail end of the second rod body 203, and the pin 13 is a hollow structure made of rubber or silicone etc. The pin 13 is sleeved on the tail end of the second rod body 203 to enhance the friction with the ground.

[0063] It should be noted that the support plate may also be configured without an adjustable telescopic portion, i.e. Figure 10-11 shown.
