Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary structures of a pedestal microphone, in particular to an anti-falling structure and a pedestal microphone. Background Art

[0002] The floor microphone includes a base, a connecting rod connected to the base, and a microphone connected to the connecting rod. The connecting rod can generally be made bendable and deformable, so that the position of the microphone can be easily adjusted during use. Such a floor microphone can be placed on a table top (or other platform), and is suitable for use in broadcasting stations, university classrooms, lectures and other scenes. In specific use, the base is also connected to a connecting wire, and sometimes the floor microphone may accidentally fall off the platform. The prior art generally adopts adding a counterweight to the base to make the base more stable, but it may still fall accidentally. For example, the user accidentally lifts the table when getting up, causing the base to slide, which may pull the connecting wire, causing the connecting wire to fall off or even be torn off, causing inconvenience in use. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an anti-falling structure, which solves the problem in the prior art that the drop of the stand-type microphone may cause the connecting wire to be pulled.

[0004] According to an embodiment of the utility model, a fall prevention structure includes a placement platform having a horizontal surface and an internal chamber, a limiting hole passing through the horizontal surface and the internal chamber, and a pull rope passing through the limiting hole, one end of the pull rope located in the internal chamber is fixedly connected to a sphere whose diameter is larger than the diameter of the limiting hole, and the other end is connected to the bottom surface of the base of the stand-type microphone; it also includes a positioning groove recessed on the horizontal surface, and a positioning block that can be accommodated in the positioning groove is fixedly connected to the base.

[0005] In the above embodiment, the placement platform with a horizontal surface and an internal chamber is similar to the table in the prior art, and the internal chamber can be the space inside the drawer of the table. The difference is that the sphere is located in the internal chamber. When placed normally, the base of the stand microphone is placed on the horizontal surface, and the sphere can fall on the inner bottom surface of the internal chamber so that the pull rope is located in the limiting hole and the internal chamber. When it falls accidentally, the base pulls the pull rope to move the sphere toward the limiting hole. The sphere is larger and is stuck in the limiting hole when it contacts the top surface of the internal chamber, thereby limiting the base from falling further and avoiding pulling the connecting wires. This solves the problem in the prior art that the falling of the stand microphone may cause pulling of the connecting wires.

[0006] Furthermore, the positioning groove is an annular groove surrounding the limiting hole, and the positioning block includes a plurality of equidistantly arranged positioning blocks.

[0007] Furthermore, the end of the pull rope facing away from the sphere is fixedly connected to the limit block, and a limit cylinder is sleeved outside the pull rope. The limit cylinder is threadedly connected to the base, and the limit block can be located in the limit cylinder.

[0008] Furthermore, the bottom surface of the limiting cylinder is higher than the bottom surface of the positioning block.

[0009] Furthermore, it also includes a counterweight block embedded in the bottom surface of the base.

[0010] Furthermore, the counterweight block is cocentrically arranged with the bottom surface of the base and the bottom surfaces are flush.

[0011] Furthermore, the pull ropes include a pair symmetrically arranged on both sides of the counterweight block, and the limiting holes include a pair corresponding to the pull ropes.

[0012] According to an embodiment of the utility model, a stand-type microphone is also provided, which includes a base, a pull rope is connected to the base, and a ball is connected to one end of the pull rope away from the base.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The spherical body is arranged to be stuck in the limit hole, thereby limiting the base from further falling and avoiding pulling the connecting wires, thus solving the problem in the prior art that the connecting wires may be pulled due to the falling of the base-type microphone.

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In an exemplary embodiment, Figure 1-3 As shown, this embodiment provides an anti-fall structure, which includes a placement platform 3 with a horizontal surface 1 and an internal chamber 2, a limiting hole 4 passing through the horizontal surface 1 and the internal chamber 2, and a pull rope 5 passing through the limiting hole 4, one end of the pull rope 5 located in the internal chamber 2 is fixedly connected to a sphere 6 whose diameter is larger than the diameter of the limiting hole 4, and the other end is connected to the bottom surface of the base 7 of the stand-type microphone; it also includes a positioning groove 8 recessed on the horizontal surface 1, and a positioning block 9 that can be accommodated in the positioning groove 8 is fixedly connected to the base 7.

[0025] In the above embodiment, the placement platform 3 having a horizontal surface 1 and an internal chamber 2 is similar to a table in the prior art, and the internal chamber 2 can be the space inside the drawer of the table. The difference is that the sphere 6 is located in the internal chamber 2. When placed normally, the base 7 of the stand microphone is placed on the horizontal surface 1, and the sphere 6 can fall on the inner bottom surface of the internal chamber 2 so that the pull rope 5 is located in the limiting hole 4 and the internal chamber 2. When an accidental drop occurs, the base 7 pulls the pull rope 5 to move the sphere 6 toward the limiting hole 4. The sphere 6 is larger and is stuck in the limiting hole 4 when it contacts the top surface of the internal chamber 2, thereby limiting the base 7 from falling further and avoiding pulling the connecting wire 11, thereby solving the problem in the prior art that the falling of the stand microphone may cause the connecting wire 11 to be pulled; specifically, the set sphere 6 can also be a ball with a heavier weight. The body 6, which can be a steel ball, can also play the role of pulling the base 7 so that the base 7 and the horizontal platform surface 1 fit closely. At this time, the pull rope 5 can be in a tensioned state, but this will not affect the movement of the base 7, that is, the base 7 can be moved by holding it and applying a greater force, so as to facilitate the cleaning and other maintenance of the horizontal platform surface 1; further, the provided positioning groove 8 and positioning block 9 can further play the role of making the combination of the base 7 and the horizontal platform surface 1 more stable, and in coordination with the pull rope 5 and the sphere 6, it can resist a small tilt of the horizontal platform surface 1 without tipping over, thereby reducing the chance of falling; further, the positioning groove 8 is an annular groove surrounding the limiting hole 4, and the positioning block 9 includes a plurality of equidistantly arranged positioning blocks 9, which are accommodated in the positioning groove 8, that is, the lateral movement of the base 7 on the horizontal platform surface 1 is limited.

[0026] like Figure 1-5 As shown, in another exemplary scheme, a pedestal microphone is also provided, including a base 7. Similar to the prior art, a connecting rod 10 and a connecting wire 11 are connected to the base 7. A microphone 12 is also connected to the connecting rod 10. The connecting rod 10 is made to be bendable and deformable, so that the position of the microphone 12 can be easily adjusted during use. A counterweight 13 is also embedded in the center of the bottom surface of the base 7. In this way, increasing the weight of the base 7 can also enhance the stability. In particular, the counterweight 13 can be located inside the base 7, or it can be flush with the bottom surface of the base 7, or slightly extend below the bottom surface. A pull rope 5 is also connected to the base 7, and a sphere 6 is also connected to the end of the pull rope 5 facing away from the base 7; more specifically, when the sphere 6 abuts against the limiting hole 4, the connecting wire 11 is in an untensioned state, thereby ensuring that the connecting wire 11 is not pulled.

[0027] like Figure 1-5As shown, the end of the pull rope 5 facing away from the sphere 6 is fixedly connected to the limiting block 15, and a limiting cylinder 14 is also sleeved on the outside of the pull rope 5, and the limiting cylinder 14 is threadedly connected to the base 7, and the limiting block 15 can be located in the limiting cylinder 14, and the limiting cylinder 14 and the base 7 can be disassembled, so as to facilitate the connection of the pull rope 5. More specifically, one end face of the limiting cylinder 14 is open, and the other end face is provided with a through hole 16 for the pull rope 5 to pass through, but the limiting block 15 cannot pass through the through hole 16, so that the end of the pull rope 5 is connected to the limiting cylinder 14; in more detail, the bottom surface of the limiting cylinder 14 is higher than the bottom surface of the positioning block 9, so that when the base 7 is placed in other positions (such as before the positioning block 9 has not entered the positioning groove 8), the limiting cylinder 14 may not be against the horizontal platform surface 1, thereby reserving a certain space for the pull rope 5 to be placed smoothly, and then move it again so that the positioning block 9 on the base 7 enters the positioning groove 8.

[0028] like Figure 1 As shown, in a further exemplary embodiment, the pull rope 5 includes a pair symmetrically arranged on both sides of the counterweight block 13, and the limiting holes 4 include a pair corresponding to the pull rope 5, so that a downward pulling effect is provided on both sides of the base 7 to enhance the stability of the base 7 on the horizontal platform 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model. .
