The rotary driving mechanism 3 in this embodiment is assembled on the first fixing portion 11, the elastic ear muff 2 in this embodiment includes an elastic ring 21, the elastic ring 21 is wound around a plurality of circles, the innermost ring of the elastic ring is sleeved on the outer side of the rotary driving mechanism 3, the radial dimension of the elastic ring can be changed when the elastic ring is acted by the rotary driving mechanism 3, and preferably, the elastic spring 21 is selected as an elastic spring; the elastic earmuff 2 further comprises a silica gel auricle sleeve 22, the silica gel auricle sleeve 22 is fixedly connected with the auricle 8, and in the embodiment, the elastic ring 21 is prevented from directly contacting with the auricle of a wearer, so that the problem of poor comfort of the wearer is caused.
Preferably, the rotation driving mechanism 3 is a first internal ratchet mechanism, the first internal ratchet specific structure includes a first ratchet housing 31, a first ratchet body 32, and a first internal pawl 33 disposed on the first ratchet body 32, a plurality of first ratchet teeth 34 spirally arranged along a circumferential direction of an inner sidewall are disposed on an inner sidewall of the first ratchet housing 31, and the first internal pawl 33 is matched with the first ratchet teeth 34. In order to realize the installation and matching with the rotating shaft 1, a first installation key slot 35 penetrating through the first ratchet body 32 and used for matching with a first installation key is formed on the first ratchet body 32. The first ratchet body 32 is fixed through the key connection between the first installation key groove 35 and the first installation key on the rotating shaft 1, and the first ratchet shell 31 is fixedly connected with the inner ring of the elastic earmuff 2, the fixing mode can be fixed in a welding fixing or interference fit mode, when the rotating shaft 1 rotates, the first ratchet body 32 and the first inscription pawl 33 can be driven to rotate, the first inscription pawl 33 acting force drives the first ratchet 34 to drive the whole first ratchet shell 31 to rotate, and because the first ratchet shell 31 in the embodiment is fixedly connected with the elastic earmuff 2 which is circumferentially wound, the radial dimension of the elastic earmuff 2 is driven to continuously increase when the first inscription pawl mechanism rotates, and the radial dimension of the elastic earmuff 2 is regulated.

Because the ratchet wheel rotates only to the single direction, the first inscription ratchet mechanism and the second inscription ratchet mechanism rotate in opposite directions, and then when the first inscription ratchet mechanism rotates under the drive of the rotating shaft 1 to adjust the diameter size of the elastic earmuff 2, the second inscription ratchet mechanism does not rotate, and at the moment, if the rotating shaft 1 is loosened, the first inscription ratchet mechanism and the elastic earmuff 2 cannot rotate in opposite directions, the positions of the first inscription ratchet mechanism and the elastic earmuff 2 can be locked through the reverse self-locking action of the second inscription ratchet mechanism, the phenomenon of the rotation of the elastic earmuff 2 is effectively avoided, the adjustment of any size range of the diameter size of the elastic earmuff 2 in a certain size range is realized, and the elastic earmuff is not used in a replacement mode with a certain gradient size, so that the elastic earmuff can meet the use requirements of different wearing people including special people such as fat people.
When the rotating shaft 1 is assembled, the rotating shaft 1 passes through the elastic earmuff 2, is fixed with the rotary driving mechanism 3 and the self-locking mechanism 4, passes through the elastic reset piece 5 and is fixed with the resisting piece 6, specifically, the elastic reset piece 5 is sleeved on the rotating shaft 1 and is positioned between the self-locking mechanism 4 and the resisting piece 6, and the resisting piece 6 is fixed on the rotating shaft 1. The resisting piece 6 is fixed at the end of the rotating shaft 1, and is used for applying an acting force to the elastic restoring piece 5 when the rotating shaft 1 is pressed, compressing the elastic restoring piece 5 to store energy, and providing axial support for the elastic restoring piece 5 when the elastic restoring piece 5 performs the restoring operation of the rotating shaft 1.
In order to facilitate the rotation operation of the rotating shaft 1, a rotating screwing piece 7 or an operation position is arranged at the end part of the rotating shaft 1, and the operation position is a screw hole, preferably, in the embodiment, a rotating screwing piece 7 is arranged, the rotating screwing piece 7 mainly provides a tool for exerting a stress end on the rotating shaft 1, preferably, a right-handed screw of the cross-shaped groove screw is selected, when the rotating shaft 1 is used, the rotating shaft 1 can rotate clockwise to be used for increasing the outer diameter of the elastic earmuff 2, and the cross-shaped groove screw is in a fastening state; the second inscription ratchet mechanism is in the self-locking state when anticlockwise rotating, so the loosening of the cross groove screw can not occur in the whole using process.
The rotary screwing piece 7 is fixedly connected with the rotating shaft 1 through the resisting piece 6, and the elastic resetting piece 5 is arranged between the self-locking mechanism 4 and the resisting piece 6; after the rotating shaft 1 is pressed, as the self-locking mechanism 4 and the ear shell 8 are fixed, the rotary driving mechanism 3 and the elastic ear shell 2 are fixed, the elastic ear shell 2 and the ear shell 8 are fixedly connected, then when the rotating shaft 1 is acted by axial pressing force, the rotary driving mechanism 3 and the self-locking mechanism 4 can slide along the axial direction of the rotating shaft 1 relative to the first fixing part 11 and the second fixing part 12 respectively, when the rotating shaft 1 slides, the resisting piece 6 compresses the elastic reset piece 5, the elastic reset piece 5 accumulates energy, and simultaneously, after the sliding, the elastic reset piece 5 is separated from the first fixing part 11 and the second fixing part 12 respectively, and enters into the smooth section of the rotating shaft 1, after the pressure of the rotating shaft 1 is eliminated, the pressure applied to the elastic reset piece 5 is eliminated, the rotating shaft 1 drives reverse movement under the reverse acting force of the elastic reset piece 5, so that the rotary driving mechanism 3 and the self-locking mechanism 4 are automatically assembled on the first fixing part 11 and the second fixing part 12. Preferably, the elastic restoring member in this embodiment is a 5 restoring spring, the main function is to ensure that the automatic reset function of the rotating shaft 1 is realized after the first inscription ratchet mechanism completes the position reset.
When the corresponding size value of the elastic ear cap 2 reaches the maximum value or a user wants to readjust and shrink the outer diameter of the elastic ear cap 2, a certain pressure can be applied to the rotating shaft 1, after the pressure is applied, the rotating driving mechanism 3, the self-locking mechanism 4 and the rotating shaft 1 are connected and fixed through keys, and can be separated from the rotating shaft 1 under the action of the pressure, namely, the first inscription ratchet mechanism enters a first smooth section of the rotating shaft 1 and is positioned between the first fixing part 11 and the second fixing part 12, the second inscription ratchet mechanism enters a second smooth section and simultaneously transmits the pressure to the elastic reset piece 5, and because the first fixing part 11 and the second fixing part 12 are of a convex staggered arrangement structure or a matching structure with the height of the first installation key being lower than that of the second installation key, the limiting of the first inscription ratchet mechanism in the axial direction can be ensured through the second fixing part 12 when the first inscription ratchet mechanism enters the first smooth section. Meanwhile, after being pressed, the first internal ratchet mechanism and the second internal ratchet mechanism enter the smooth section of the rotating shaft 1 and are not subjected to the reverse self-locking effect of the second internal ratchet mechanism, the first internal ratchet mechanism can reversely rotate under the reverse acting force of the elastic earmuff 2 to return to the initial position, and meanwhile, after the pressure applied to the rotating shaft 1 is eliminated, the rotating shaft 1 can drive the rotating shaft 1 to reset under the reverse acting force of the elastic reset piece 5, so that the assembly with the first internal ratchet mechanism and the second internal ratchet mechanism is realized.
Preferably, the second mounting key slot 45 on the second ratchet body 42 has a longer length than the first mounting key slot 35, and the length of the second fixing portion 12 is greater than the length of the first fixing portion 11, so as to limit and guide the operation of the second fixing portion 12 on the rotating shaft 1 when the elastic restoring member 5 is restored, so as to realize the mounting fit with the second mounting key slot 45.
Further, in this embodiment, the distance between the first fixing portion 11 and the second fixing portion 12 is larger than the width of the first inscribed ratchet mechanism, so as to ensure that the first ratchet mechanism can be completely located in the first smooth section on the rotating shaft 1 after being separated from the first fixing portion 11, so as to realize the reverse rotation of the elastic ear muff 2, and reset the elastic auricle 2.
The first fixing part 11 and the second fixing part 12 are arranged in a staggered way: the central angle value of the arc length corresponding to the rotation axis between the first fixing portion 11 and the second fixing portion 12 is preferably 20-90 degrees. Of course, other angles are also possible, as long as the first fixing portion 11 and the second fixing portion 12 are arranged in a staggered manner, so that after the first inscription ratchet mechanism is separated from the first fixing portion 11, the first inscription ratchet mechanism is limited by the second fixing portion 12 when the rotating shaft 1 is reset under the reverse acting force of the elastic reset member 5, and the first installation key slot 35 of the first inscription ratchet mechanism is prevented from being matched with the second fixing portion 12, and the function of complete automatic reset cannot be realized.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
