Description

Technical Field

[0001] The utility model relates to a rotation position regulating mechanism. Background Art

[0002] With the development of society, many wearable devices have appeared in people's lives. For example, during stage performances, performers need to wear head-mounted microphones. Sometimes performers are required to sing and dance, so even when the performers perform violent movements, the microphone is required to remain in a fixed position relative to the mouth. Otherwise, the distance between the microphone and the performer's mouth is inconsistent, resulting in abnormal sound transmission and greatly reduced singing effect. In addition, since most performers have different face shapes, ear positions, etc., each performer has their own requirements for the position of the microphone.

[0003] Most existing head-mounted microphones are of fixed style or fixed structure, lacking the ability to be flexibly adjusted according to the needs of individual performers. Moreover, due to the fast tempo of singing and dancing performances, performers sometimes need to be able to quickly adjust and fix the microphone position.

[0004] By analogy, some devices or equipment also have a mechanism that requires adjusting the relative position between two components, especially the rotational position between the two components, and after the rotational position is adjusted, the two components need to be firmly fixed at the position.

[0005] Therefore, not only in the field of head-worn microphones, but also in many other fields, there is a need for a mechanism that can flexibly and quickly adjust the rotational positions between components and then quickly lock them. Utility Model Content

[0027] In view of the above-mentioned shortcomings in the prior art, the utility model provides a rotation position adjustment mechanism, which is used to adjust the rotation position between a first component and a second component.

[0028] The present invention will be described below by taking a rotation position adjustment mechanism for a microphone as an example with reference to the accompanying drawings.

[0029] Figure 1 The microphone after the rotation position adjustment mechanism is assembled and the microphone after the rotation position adjustment mechanism is disassembled. It should be understood that the microphone after the rotation position adjustment mechanism is disassembled. Figure 1 , the first part 8 corresponds to the ear hook frame of the microphone, and the second part 9 corresponds to the gooseneck rod of the microphone. It should be understood that the gooseneck rod can be a structure with a certain rigidity relative to the soft wire, for example, formed by metal or hard plastic to protect the wire inside it, etc. The earphone frame can include a skeleton for wearing on the head and a hook-shaped part for hanging on the ear, etc.

[0030] Figure 2 The first component 8 and some components of the rotation position adjustment mechanism are shown, the first component 8 also includes a fixed portion 81, and the second component 9 can rotate relative to the fixed portion 81. It should be understood that the "fixed" mentioned here is a relative concept, which means that in the process of adjusting the rotation position between the first component 8 and the second component 9, the first component 8 and its fixed portion 81 are basically fixed or immobile, and the operator can operate the second component 9 to rotate relative to the first component 8 to a desired position.

[0031] For example, in a microphone, since the ear hook frame is worn on the performer's head, the position of the ear hook part as the first component 8 relative to the performer's head is basically fixed and unchanged, and the performer can operate the gooseneck rod as the second component 9 to rotate relative to the ear hook part, thereby adjusting the position of the microphone pickup at the end of the gooseneck rod. As shown in the figure, the fixed part 81 is a bent part with a bent shape. Therefore, it should be understood that for different forms of the first component 8, the fixed part 81 can also have different forms.

[0032] Figure 3 A cross-sectional view of the rotational position adjustment mechanism is shown.

[0033] According to the preferred embodiment shown, the rotation position adjustment mechanism comprises: a first adjustment member 1, comprising a body 11 and a head 12 at one end of the body 11, wherein a through hole 13 (see FIG. 1 ) is provided in the middle of the body 11 for allowing the second member 9 to pass through. Figure 6 ), and the head 12 can engage with the fixed part 81; the second adjusting member 2 can engage with or release the first adjusting member 1 at the other end of the body 11 opposite to the one end, so that the rotational position adjustment mechanism is correspondingly in the locked position or the adjustable position, so that when the rotational position adjustment mechanism is in the adjustable position, the second component 9 can rotate relative to the fixed part 81, and when the rotational position adjustment mechanism is in the locked position, the first adjusting member 1 and the second adjusting member 2 clamp the first component 1 and the second component 9 and lock them therebetween.

[0034] By means of the rotation position adjustment mechanism of the present invention, when the microphone as shown in the figure needs to be adjusted, the engagement between the first adjustment member 1 and the second adjustment member 2 can be released, so that the second component 9 can be rotationally adjusted relative to the first component 8, especially the fixed portion 81 thereof (such as Figure 1 ), after reaching the desired position, the first adjusting member 1 and the second adjusting member 2 are engaged again to clamp and lock the first component 8 and the second component 9 therebetween.

[0035] It should be understood that the first adjusting member 1 may have a structure of a substantially cylindrical body 11 and a head 12 of a slightly larger diameter as shown in the figure, and the other end of the body 11 of the first adjusting member 1 may have a thread, and the second adjusting member 2 may be configured as a nut engaged with the thread. Of course, any other adjustable engagement structure, such as a snap-fit ​​structure, etc., may also be adopted, as long as the first adjusting member 1 and the second adjusting member 2 can be engaged to clamp and lock the first component 8 and the second component 9 therebetween.

[0036] Further preferably, in order to optimize the locking and adjustment between the first component 8 and the second component 9, the rotation position adjustment mechanism may further include a stopper 3, the stopper 3 having a receiving portion 39 (such as Figure 4 and 5 ), so that the fixing portion 81 can be held between the first adjusting member 1 and the stopper 3, and the body 11 of the first adjusting member 1 can pass through the stopper 3. The stopper 3 has, for example, an annular shape, and its diameter is substantially equal to the diameter of the head 12 of the second adjusting member 2. Such a stopper 3 can better hold the first component 8, so as to prevent the first component 8 from being separated from the rotation position adjustment mechanism during the adjustment process.

[0037] Further preferably, the limiting member 3 may include a limiting notch 30 provided at the edge of the accommodating portion 39 , and both ends of the limiting notch 30 may abut against the limited portion of the fixing portion 81 .

[0038] Taking the microphone as an example, the limited parts are the two ends of the bent part of the ear hook frame (such as Figure 2 By providing the limiting notch 30 and the accommodating portion 39, the fixing portion 81 can be better adapted to the bending profile and accommodate the fixing portion 81. In particular, when the ear hook frame portion 82 above the fixing portion 81 is in a form of expanding outward from both ends of the fixing portion 81, the limiting notch 30 can clamp the expanded portion 82, thereby further ensuring the position between the first component 8 and the limiting member 3.

[0039] More preferably, see Figure 2-5 The rotation position adjustment mechanism may further include a friction enhancement member 4, and the friction enhancement member 4 includes a portion engaged with the stop member 3 and a portion through which the second component 9 can pass, that is, the friction enhancement member 4 may have a through hole 42 (such as Figure 5 As shown in FIG. 1 ), the friction enhancement member 4 and the second component 9 are substantially integrated. When the first adjusting member 1 and the second adjusting member 2 are locked, there is a greater friction force between the friction enhancement member 4 and the stop member 3. Compared with the second component 9 directly contacting the stop member 3, the friction enhancement member 4 can better prevent the second component 9 from accidentally rotating relative to the stop member 3.

[0040] More preferably, if Figure 4-5 As shown, the portion of the friction enhancing member 4 that engages with the stopper 3 is set as a flange 41, and the stopper 3 includes a recess 31 that matches the flange 41, so that when the first adjusting member 1 is in the locking position, the flange 41 and the recess 31 are squeezed together. This squeezing further enhances the friction engagement between the stopper 3 and the friction enhancing member 4. Alternatively, according to a preferred embodiment not shown, the portion of the friction enhancing member 4 that engages with the stopper 3 can be set as a recess, and the stopper 3 can include a flange that matches the recess, so that when the first adjusting member 1 is in the locking position, the flange and the recess are squeezed together.

[0041] According to a preferred embodiment not shown, instead of the above-mentioned flange and recess structure, the friction enhancement member 4 and the limit member 3 may respectively include friction enhancement textures that can cooperate with each other. For example, the surfaces that are engaged with each other may be roughened or have a specific surface texture, as long as the friction between the two can be increased.

[0042] More preferably, see Figure 2-3 and Figure 6 The head 12 of the first adjusting member 1 may include an elastic material 14 (such as TPE material) coated thereon, so that when the first adjusting member 1 is in the locking position, the elastic material 14 at least contacts the fixed portion 81; for example, when there is a limiter 3, the elastic material 14 may also contact the limiter 3. Since the rotation position adjustment mechanism of the utility model needs to be adjusted repeatedly for many times, by providing a relatively soft elastic material 14, the contact between the head 12 and the fixed portion 81 and / or the limiter 3 can be improved to avoid damage to components caused by rigid contact.

[0043] In addition, in order to increase the strength of the friction reinforcing member 4 and the stopper 3, the friction reinforcing member 4 and the stopper 3 may be formed of a material to which glass fiber is added.

[0044] Further preferably, the rotation position adjustment mechanism further includes a washer 5 disposed between the second adjustment member 2 and the second component 9 to improve the contact between the two.

[0045] In summary, the utility model provides an adjustment mechanism for adjusting the rotational position between two microphones, which is particularly suitable for occasions such as head-mounted microphones that require frequent adjustment and quick locking.

[0046] The exemplary implementation modes of the present disclosure are described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
