Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically to a wireless transmission microphone adapter. Background Technology

[0002] A wireless microphone adapter is a key device for enabling interconnection between wireless microphone systems and different devices. Because the output interface of a wireless microphone receiver differs structurally from the input interfaces of mobile phones, cameras, computers, and other terminal devices, the adapter effectively solves the compatibility issues across platforms by configuring replaceable adapter connectors.

[0003] In existing technologies, adapter connectors generally adopt a fixed, exposed design, as shown in the wireless transmission microphone adapter disclosed in Chinese patent CN216357212U. This traditional design has obvious drawbacks: the basic connector is exposed for a long time, making it susceptible to mechanical damage from physical collisions or bending, and also prone to poor contact due to dust accumulation; at the same time, the exposed connector is very easy to snag on other devices during transportation and storage, significantly increasing the risk of equipment damage. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a wireless transmission microphone adapter, the basic connector of which can be stored when not in use, so as to avoid the possibility of the basic connector being exposed to the outside and damaged by external influences, thereby solving the technical problems described in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A wireless transmission microphone adapter includes a housing with an inner cavity, a through hole communicating with the inner cavity on the surface of the housing, a base connector movably installed in the through hole, and an ear fixedly provided at one end of the base connector extending into the inner cavity.

[0007] A sliding rod is fixedly connected to the cavity wall of the inner cavity. The support lug is slidably assembled on the sliding rod. An adjustment mechanism is connected to the support lug. When the support lug moves along the sliding rod under the action of the adjustment mechanism, the base joint can move out or be stored in the inner cavity.

[0008] Furthermore, the adjustment mechanism includes a knob rotatably mounted on the surface of the housing, and a support rod A and a support rod B are fixedly connected to the inward side of the knob and the support lug, respectively, with the center line of the support rod B being parallel to that of the support rod A.

[0009] A connecting rod is hinged together between support rod A and support rod B.

[0010] Furthermore, support rod A and support rod B each have a connecting portion, the diameter of which is smaller than the diameter of the support rod;

[0011] The two ends of the connecting rod are respectively connected to two connecting parts, and the ends of the connecting parts are fixedly connected to a limiting member for restricting the axial movement of the connecting rod along the connecting part.

[0012] Furthermore, two fixing members are fixedly connected to the cavity wall of the inner cavity. The two fixing members are respectively located at the starting end of the movement path of the support rod A, and are used to limit the movement stroke of the support rod A.

[0013] The fastener includes a mounting portion fixedly connected to the housing, and a fixing portion integrally formed with the mounting portion, the fixing portion being used to clamp the support rod A.

[0014] Furthermore, a support is integrally formed on the outer surface of the housing near the through hole, and a rotating shaft is rotatably connected in the support;

[0015] The shaft is integrally formed with a connecting strip, and a cap for sealing the through hole is fixed at the other end of the connecting strip.

[0016] Furthermore, a through groove is provided on the surface of the housing, the knob is installed in the through groove, and the inward-facing surface of the knob is in contact with the surface of the fixing member.

[0017] Furthermore, an indicator mark is integrally formed on the outward-facing side of the knob, and an indicator line is present on the outer surface of the housing.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. When not in use, the base connector of this utility model can be moved and completely stored in the housing by the adjustment mechanism. Compared with the base connector of the prior art which is exposed, the base connector has better protection and can reduce the impact of physical wear and electromagnetic interference (such as proximity to power cords) on the base connector, resulting in a longer service life. In addition, the overall structure is more compact and lightweight after storage, and can be safely carried without an additional protective box, which greatly improves the convenience of use.

[0020] This invention achieves comprehensive improvements in protection, portability, and durability while ensuring functional integrity, providing a more optimized solution for wireless audio adapters.

[0021] 2. When the base connector of this utility model is extended or retracted, it is only necessary to rotate the knob, which makes the operation more convenient. In addition, the fixing component can effectively restrict the free movement of the base connector, making the use process more stable.

[0022] 3. The cap and telescopic double protection of this utility model have a tighter gap and can isolate moisture or dust, making it especially suitable for outdoor use. Attached Figure Description

Detailed Implementation

[0028] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0029] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] Please see Figure 1 and Figure 4This utility model provides a technical solution: a wireless transmission microphone adapter, including a housing 1 with an inner cavity 2. The top surface of the housing 1 has a through hole 3 communicating with the inner cavity 2. A base connector 4 is movably installed in the through hole 3. The base connector 4 can be a Lightning or Type-C connector in the prior art for connecting to Apple or Android devices. Furthermore, an expansion connector, such as a USB adapter, can be inserted into the base connector 4 as needed, so that it can be directly plugged into a computer for use. The replacement and use of the connectors is already relatively mature in the prior art, and will not be described in detail here.

[0031] Please see Figure 1 , Figure 3 and Figure 4 The base connector 4 has a support lug 5 fixedly attached to one end of its extension into the inner cavity 2. A slide rod 6 is fixedly connected to the cavity wall of the inner cavity 2. The support lug 5 is slidably mounted on the slide rod 6. An adjustment mechanism 7 is connected to the support lug 5. A through groove 13 is provided through the surface of the housing 1.

[0032] Specifically, the adjustment mechanism 7 includes a knob 71 rotatably mounted in the through groove 13. Support rods A72 and B73 are fixedly connected to the inward-facing side of the knob 71 and the lug 5, respectively. Support rod B73 is parallel to the centerline of support rod A72. Support rod A72 is eccentrically positioned on the knob 71. A connecting rod 74 is hinged between support rods A72 and B73. Thus, when the knob 71 is rotated, the knob 71 drives the support rods. A72 makes a circular motion, and the lower end of the connecting rod 74 follows the synchronous circular motion of the support rod A72 under the action of the support rod B73. The upper end of the connecting rod 74 pulls the support lug 5 along the slide rod 6 through the support rod B73, thereby enabling the base connector 4 to be extended out of the housing 1 for use or stored in the inner cavity 2 when not in use by rotating the knob 71. This protects the base connector 4 and reduces the impact of physical wear and electromagnetic interference (such as proximity to power lines) on the base connector 4, resulting in a longer service life.

[0033] Please see Figure 4The support rods A72 and B73 each have a connecting part 741. The diameter of the connecting part 741 is smaller than the diameter of the support rod. The two ends of the connecting rod 74 are respectively inserted into the two connecting parts 741. The end of the connecting part 741 is fixedly connected to a limiting member 75. The limiting member 75 can be a bolt. By screwing the limiting member 75 into the connecting part 741, the axial movement of the connecting rod 74 can be restricted. This allows the connecting rod 74 to rotate only relative to the support rod, so that when the knob 71 is rotated, the corresponding movement of the base joint 4 can be controlled. It can also stably connect the knob 71 and prevent the knob 71 from axially disengaging from the through groove 13.

[0034] Please see Figure 3 Two fixing members 8 are fixedly connected to the cavity wall of the inner cavity 2. The surface of the knob 71 facing inward is in contact with the surface of the fixing member 8. The two fixing members 8 are respectively located at the starting end of the movement path of the support rod A72, and are used to limit the movement stroke of the support rod A72.

[0035] The fastener 8 includes a mounting part 81 fixedly connected to the housing 1, and a fixing part 82 integrally formed with the mounting part 81. The fixing part 82 is made of plastic material and is used to deform and clamp the support rod A72. When the base joint 4 is fully extended from the through hole 3, the support rod A72 is engaged in one of the fixing parts 82, thereby restricting the rotation of the knob 71 and ensuring the stable insertion structure of the base joint 4. At this time, the connecting rod 74 can act as a diagonal brace to support the base joint 4, so that the base joint 4 is not easy to loosen after extending from the through hole 3.

[0036] When the base connector 4 is fully retracted into the inner cavity 2 under the action of the adjustment mechanism 7, the support rod A72 is engaged with another fixing member 8 so that the base connector 4 is stably housed in the inner cavity 2.

[0037] Please see Figure 1 The knob 71 has an integrally formed indicator mark 14 on its outward-facing side. The outer surface of the housing 1 has an indicator line 15, which is used to indicate the rotational operation direction of the knob 71 in controlling the extension or retraction of the base connector 4 into the inner cavity 2. The indicator mark 14 is used to rotate the knob 71 and can also cooperate with the protrusion (not shown) on the outer surface of the housing 1 to serve as a reminder. When the indicator mark 14 is aligned with the protrusion, the support rod A72 is engaged and fixed with the fixing member 8.

[0038] Please see Figure 1 and Figure 2A support 9 is integrally formed on the outer surface of the housing 1 near the through hole 3. A rotating shaft 10 is rotatably connected to the support 9. A connecting band 11 is integrally formed on the outside of the rotating shaft 10. A cap 12 for sealing the through hole 3 is fixed at the other end of the connecting band 11. The connecting band 11 and the cap 12 are made of silicone. When the base connector 4 is fully inserted into the inner cavity 2, the cap 12 can be rotated to seal the opening of the through hole 3, thereby isolating moisture or dust.

[0039] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
