Description
Technical Field
The invention relates to the field of microphones, in particular to a locking nut for a microphone.
Background
The microphone is a transducer for converting acoustic signals into electric signals, and a test capacitor microphone is generally adopted in a sound level meter, and has the characteristics of stable performance, wide dynamic range, flat frequency response, small volume and the like.
The condenser microphone comprises a shell, a rear pole plate combination, a locking nut and the like, wherein the rear pole plate combination is placed in the shell and then is pressed from the back through the locking nut, and the locking nut is engraved with numbers and models, and the numbers and the models are clearly marked and cannot be scratched. The existing locking nut is generally engraved on the surface of an end face, and is easily scratched by a tool in the mounting and dismounting processes, so that the number and the model are blurred. In addition, the position of the existing locking nut for placing the screwdriver is not guided, so that the screwdriver is not easy to enter the dismounting hole.
Disclosure of Invention
The invention aims to solve the technical problem of providing a lock nut for a microphone, which has a simple structure, is not easy to scratch the serial number and the model mark of the end surface, and is easy to install and disassemble.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the utility model provides a lock nut for microphone, includes nut body, external screw thread portion, recess, guide way, through-hole, nut body excircle is equipped with external screw thread portion be equipped with on the nut body terminal surface the recess, be equipped with at same terminal surface with the nut body is concentric and runs through the through-hole of nut body the recess with be equipped with between the through-hole the guide way, the guide way center with the coincidence of through-hole center.
Preferably, the groove has a cross section of
And (4) shaping.
Further preferably, the shape of the groove is a partial circular ring, and the center of the circular ring coincides with the center of the nut body.
Preferably, the axial section of the guide groove is conical, and an acute included angle between a conical generatrix and the central axis of the nut body is 30-50 degrees.
Preferably, the through-hole has a regular hexagonal shape.
Further preferably, the size of the regular hexagon is the same as the size of a hexagon nut of a standard hexagon bolt.
Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: the invention is provided with a section of
The serial number and the model of the groove can be carved in the groove, so that the groove is not easy to scratch and plays a role in numbering and modelingProtection; the nut driver is also provided with the guide groove, so that the special driver can be guided, the driver cannot slide on the end surface of the nut, the scratch of the end surface of the nut by the driver is reduced, the driver can easily enter the through hole to be installed and disassembled, and the disassembling and assembling time of the nut is shortened.
Drawings
FIG. 1 is a schematic view of the cross-sectional structure A-A of the present invention;
FIG. 2 is a front view of the present invention;
in the figure: 1. the nut comprises a nut body 2, an external thread part 3, a groove 4, a guide groove 5 and a through hole.
Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in figures 1-2, the locking nut for the microphone comprises a nut body 1, an external thread part 2, a groove 3, a guide groove 4 and a through hole 5, wherein the external thread part 2 is arranged on the excircle of the nut body 1, the groove 3 is arranged on one end surface of the nut body 1, and the section of the groove 3 is
The shape of the groove 3 is a partial circular ring, the length of the circular ring can be determined according to the number and the model of the locknut, and the center of the circular ring is superposed with the center of the nut body 1. Be equipped with on same terminal surface with nut body 1 concentric and through nut body 1's through-hole 5, through-hole 5 shape is regular hexagon, and regular hexagon size is the same with standard hexagon bolt's hexagon nut size, if the hand does not have special bottle opener during the dismouting, can directly use assorted hexagon bolt as the instrument, perhaps directly repacks into specialized tool with hexagon bolt, makes things convenient for the maintenance personal to operate. A guide groove 4 is arranged between the groove 3 and the through hole 5, the center of the guide groove 4 is coincided with the center of the through hole 5, and the guide groove 4 is axially brokenThe surface is conical, and the included angle between the conical generatrix and the central axis of the nut body 1 is 30-50 degrees, preferably 45 degrees.
When the locking nut is used, the locking nut is a plane end face and is tightly attached to an insulating sheet, the end face provided with the groove 3 and the guide groove 4 faces outwards, a special screwdriver firstly extends into the through hole 5 along the guide groove 4, the hexagonal shape of the through hole 5 is matched with the shape of the screwdriver, and then the screwdriver is rotated to screw the nut. Similarly, when the screwdriver is detached, the screwdriver is stretched into the through hole 5 to rotate. When the lock nut is mounted and dismounted, the number and the model of the nut are engraved in the groove 3, and the screwdriver extends into the through hole 5 and is provided with the guide groove 4 as a guide, so that the number and the model of the lock nut cannot be scratched due to mounting and dismounting.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
