The present invention relates to a microphone holder rotating structure, and more specifically, to a microphone holder rotating structure that allows the angle to be adjusted above a certain external force required for a long time without additional tightening even when used for a long time.

There are many types of microphone stands for fixing microphones, and most of them can be adjusted in height to suit each purpose.

However, according to the taste or habit of the person using the microphone and the microphone stand, the microphone is directed to a specific angle and for this purpose, the microphone stand connecting the microphone stand and the microphone has a hinge structure rotatably.

3 is a cross-sectional view showing a conventional microphone holder, a microphone fixing portion 21 into which the handle 1 of the microphone is inserted and fixed, and a first coupling hole penetrating integrally extending downward from the microphone fixing portion 21 ( The microphone mounting hole (2) is formed 22, the lower portion is coupled to the upper end of the vertical rod (3) of the microphone stand and the upper portion is formed with an incision (41) cut in a predetermined width vertically down the microphone mounting A vertical rod fixing fixture 4 having a lower portion of the sphere 2 inserted therein and having a second coupling hole 42 corresponding to the first coupling hole 22 formed at both sides of the cutout, and the first and second coupling holes. A microphone holder composed of a bolt 11 and a nut 12 assembled through and connecting 22 and 42 is shown.

That is, when the bolts 11 and the nut 12 are narrowed at a predetermined interval, the two cutouts 41 apply pressure to the lower part of the microphone mounting holes 2, so that the microphone mounting holes are only above a certain back force due to an increase in frictional force. The angle of (2) can be adjusted.

However, the friction between the incision part 41 and the microphone mounting opening 2 due to the repeated angle adjustment operation causes problems such as wear and friction of the surface to be reduced. 11) has a problem that is loose if you do not tighten the nut (12).

In addition, if too tightly tightened again if you do not have the problem of adjusting the angle with a very large force also occurs.

The present invention was developed to solve the above problems, the object of which is to improve the rotation structure of the microphone holder to be able to adjust the angle only under a certain external force conditions intended by the first user even in a number of uses.

In addition, it is to prevent the coupling portion from loosening by repeated operation.

In order to achieve the above object, the present invention provides a microphone fixing portion to which the handle of the microphone is inserted and fixed, a microphone mounting hole which is formed to extend from the microphone fixing portion to a lower portion and has a first coupling hole therethrough, and a microphone below. It is coupled to the upper end of the vertical rod of the stand and the upper portion is formed in the incision cut in a predetermined width down vertically is inserted into the lower portion of the microphone mounting hole and the second coupling hole corresponding to the first coupling hole is formed on both sides of the incision A microphone holder comprising a vertical rod fixture and bolts and nuts assembled through the first and second coupling holes.

Each of the first and second coupling holes has an insertion groove having an inner diameter extending outwardly to a predetermined depth, has an outer diameter corresponding to the inner diameter of the first and second coupling holes, and has a predetermined inner diameter at an end thereof, A screw hole in which a thread is formed is formed, and the other end thereof includes: a first fastener having a bolt head inserted corresponding to one of the insertion grooves;

A thread is formed on the outer circumferential surface of one side to be coupled to correspond to the screw hole, and the other side is rotatably coupled to the microphone mounting device and the vertical rod fixture by a second fastener having a bolt head inserted corresponding to one of the insertion grooves. ;

The washer and the spring are mounted between the first and second coupling holes and the respective bolt heads.

In addition, the spring has a shape of a washer and is cut in the normal direction from the center has a shape that the cut surface is distorted mutually to have a repulsive force to the compressive force.

Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

1 is a perspective view according to an embodiment of the present invention, Figure 2 is an exploded perspective view according to an embodiment of the present invention, the microphone fixing part 21 is fixed to the microphone handle 1 is inserted, the microphone height The microphone mounting holes 2 extending downward from the top portion 21 integrally and having a first coupling hole 22 formed therethrough, and coupled to the upper end of the vertical rod 3 of the microphone stand, and the upper portion vertically A cutout portion 41 cut down to a predetermined width is formed so that a lower portion of the microphone mounting hole 2 is inserted, and a second coupling hole 42 corresponding to the first coupling hole 22 is moved to both sides of the cutout portion. In the microphone holder consisting of a vertical rod fixture (4) is formed, and the bolt (11) and nut (12) assembled by connecting the first and second coupling holes (22, 42) through;

Each of the first and second coupling holes 22 and 42 has an insertion groove 43 having a predetermined depth, the inner diameter of which is extended outward, and is formed at an inner diameter of the first and second coupling holes 22 and 42, respectively. A screw hole 51 having a corresponding inner diameter and a screw thread formed on an inner circumferential surface thereof with a predetermined inner diameter is formed at the end thereof, and the other end has a bolt head 52 inserted corresponding to one of the insertion grooves 43. A first fixture 5;

The outer circumferential surface of one side is formed by the second fastener (6) having a bolt head 61 is formed to be coupled to correspond to the screw hole 51 and the other side is inserted corresponding to one of the insertion groove (43) To rotatably couple the microphone fitting 2 and the vertical rod fixture 4;

The washer 7 and the spring 8 are mounted between the first and second coupling holes 22 and 42 and the bolt heads 52 and 61, respectively.

In the structure of the present invention, the second fastener 6 is coupled to the screw hole 51 of the first fastener 5 to tighten the gap between the two bolt heads 52 and 61, thereby reducing the incision 41. Both sides of the structure were configured to be in close contact with the microphone mounting portion 2.

In the case of the combination of the bolt and the nut is a screw thread is formed directly on the outer peripheral surface of the prior art, the inclined surface of the thread directly contact the inner peripheral surface of the first and second coupling holes (22, 42), the contact surface is minimized, but the thread inclined in a certain direction is The bolts and nuts are loosely loosened to minimize the problem of loosening the bolts and nuts.

In addition, the spring 8 is positioned between the two bolt heads 52 and 61, and the washer 7 is positioned between the spring 8 and the insertion groove 43. In order to prevent falling, if both sides of the bolt head (52, 61) and the bottom surface of the insertion groove 43 is in direct contact with the friction caused by the rotation, this also has a fear of loosening due to the increase in friction, but the present invention The bottom of the insertion groove 43 and the washer (7), the spring (8), the bolt head (52, 61) in order to minimize the transfer of rotational force is also minimized the loosening of the coupling.

In addition, the most important part in the present invention is to receive a compressive force by the spring (8), the effect of this spring brings a number of advantages beyond easily predictable.

One of them is that when the initial rotation, the static friction force is applied, and after the start of the rotation, the static friction force disappears momentarily. The resistance of the static frictional force is changed to the force for compressing the spring (8) is to be rotated smoothly so as to reduce the difference in the large force even in a stationary situation or rotation.

In addition, when too tightly tightened between the first fastener 5 and the second fastener 6, the operation may be very stiff, but this problem is reduced by the elasticity of the spring 8, and the Even when the first fastener 5 and the second fastener 6 are relatively loose, the spring 8 expands to prevent rotation with a basic compression force, thereby minimizing the bending of the rotary part by the weight of the microphone.

That is, the spring (8) not only makes the rotation of the stator more smooth, but also prevents the first and second fasteners 5 and 6 from being loosened and adjusts the interval to rotate by the first constant external force for a long time use. Even if it does not deviate greatly from the initial setting value, it will not suddenly loosen or loosen.

In addition, in the present invention, the spring 8 has a shape of a washer and has a shape in which the planes cut and cut in the normal direction from the center have a shape in which they are distorted mutually and have a repulsive force to the compressive force.

As the type of spring that can be used in the present invention, various types such as a general coil spring, a dish spring, and a wave spring may be used.

However, since it does not require a large range of contraction or expansion, the coil spring requires a large length in the axial direction, which is not suitable for a compact microphone holder.

The spring structure proposed by the present inventors can be easily applied and used by those skilled in the art. However, the coil spring can be sufficiently effective even when the coil spring is extremely short in shape and easy to manufacture. It has one advantage.

As described above, the present invention has an advantage that the microphone holder can be rotated smoothly even at a static friction force or excessive tightening at all times to be used more stably and conveniently.

In addition, the combination of the first fastener and the second fastener does not change even long-term use in the position set by the first user has the effect of reducing the inconvenience of tightening again during use.
