Therefore, the present invention has stable connection, not fragile, long service life; Head circle can adopt MODIFIED PP material to make, the feature that cost is low.
As preferably, the rotating shaft that described metallic support comprises rectangle base plate, is located at two pieces of vertical baffle plates at base plate two ends and is located on two pieces of vertical baffle plates, described base plate is provided with the through hole of several rows for shaping connection; Metal arc slide is connected with rotating shaft respectively with plastic cement arc sliding sheet.
When one-body molded, liquid MODIFIED PP material can enter in through hole, and when MODIFIED PP material cooled is fixed, two metallic supports and Tou Quan are fixed into and are integrated.
The vibrational power flow of metallic support makes metallic support can enclose stable being fixedly connected with head, the setting of rotating shaft makes travelling arm of the present utility model can rotate around rotating shaft, it can use by ear with grasped two ear muffs by user, the power adjustability that earmuff applies is good, wears more comfortable.
As preferably, described Tou Quan two ends are respectively equipped with rectangle head circle end cap, and Tou Quan bottom is provided with the rectangular indentation for exposing in the middle part of metallic support; The edge of each metallic support is equipped with several extension blocks, each extension block is all between Tou Quan and head circle end cap; Head circle end cap and Tou Quan removably connect.
The setting of head circle end cap, had both made the connection between head circle and metallic support more stable, and had made again metallic support edge be hidden within head circle end cap, avoid metallic support to damage user's head.
As preferably, with the spacing block set medial surface of each plastic cement arc sliding sheet corresponding to rotating shaft junction is equipped with for coordinating with head circle end cap.
The setting of spacing block set, travelling arm of the present utility model can be rotated between the angle that end cap lower limb is enclosed in Tou Quan end bearing of trend to the spacing block set contact of travelling arm to the end, thus travelling arm is rotated within the specific limits, travelling arm is not fragile.
As preferably, each plastic cement arc sliding sheet lower end is equipped with hook plate, and each hook plate front end is equipped with cross section spacing raised line triangular in shape; The metal arc slide lower end corresponding with hook plate is provided with rectangular indentation.Hook plate is used for and is located at position limiting structure in arc-shaped cavity and matches, thus travelling arm can not be departed from by arc-shaped cavity.
As preferably, the medial surface of each plastic cement arc sliding sheet is equipped with the guide chute that 2 glide directions along travelling arm extend.
Therefore, the utility model has following beneficial effect: (1) stable connection, not fragile, long service life; (2) head circle can adopt MODIFIED PP material to make, and cost is low.
