Description

The collapsible winter protection earmuff that places

This utility model relates to a kind of winter protection article next to the shin, refers to a kind of winter protection earmuff especially.

Society goes up in the middle of the articles for use next to the shin of resisting cold now; general as thick and heavy medicated clothing, scarf, glove ... Deng; it mainly is most surface formation coating at the human body body; can reach resistance to colds invasion and attack and the warming effect of body; but work as cold snap, or be in alpine belts such as low temperature, then above-mentioned resisting cold articles for use promptly can't form protection to the human body ear; thereby the ear that exposes promptly is very easy to cause phenomenons such as cold injury and pain.

In view of the above, intentionally the personage designs some earmuffs that resisting cold is used at ear, it normally is provided with earmuff in earmuff headband and flexible support body both sides, and make earmuff headband and flexible support body hang on head, and coat ear with earmuff and endure cold in order to preventing, but, human body head respectively is different curve radians, and earmuff headband and flexible support body are hung on the head, when human body was engaged in vairious activities, earmuff headband and flexible support body were easily to front slide, and the related earmuff that causes produces tilt displacement on ear, could reply the comparatively comfortable angle of wearing and must often adjust, moreover when headband was put on the crown, Chang Wufa collocation medicated cap used, and made the earmuff user, must between medicated cap and earmuff, make selection, thereby reduce the suitability of this series products.

And be in all the year round in the microthermal climate country; people are essential to dress the in addition warming resisting cold of thick and heavy medicated clothing; often utilization winter protection earmuff is in ear in the warming and protection; yet; the design of head-type earmuff also can't be suitable for all common people and be used; easily generation is dizzy to wear head over a long time, and causes the generation of wearing phenomenons such as uncomfortable pain.

And this structural design does not have folding placing property yet, to cause that to put nowhere also be to take puzzlement point such as excessive space when not using at ordinary times, also very easy taking because of hand caused extruding, and the binding site that makes this structure produces phenomenon of rupture, and must abandon and be upgraded, this also shows that the earmuff of this class formation still has the utmost point to treat further to improve the space.

Because the existence of the problems referred to above, this creator studies intensively with great concentration, and integrate the shortcoming of above-mentioned known structure, then work out adopt adjustable lock ring ring with wearing in head dorsal part mode, reach the comfortableness that increases its use and wear scope, and be coated on ear via the both sides complete applying of snapping earmuff housing, reach the effect of resisting cold ear and warming cervical region, and possess the folding characteristic that is easier to carry that places.

The purpose of this utility model provides a kind of collapsible earmuff that places the back band mode of the use that is easy to carry about with one.

The purpose of this utility model is achieved in that a kind of collapsible winter protection earmuff that places, the structure that it is characterized in that it mainly is by an adjustable lock ring ring group, two earmuff housings and outer sewing winter protection cloth constitute, wherein, lock ring ring group is made up of two headbands that are half crooked shape, make a plurality of ratchets in a headband inner edge wherein, the place is provided with the snapping ring in addition in the mutual snapping of double headed roller, be provided with the snapping point that engages with ratchet in the snapping ring, headband root edge place is provided with runs through shrinkage pool and convex clip tenon buckle pieces, two earmuff housings are to be annulus mid portion Openworks shape, be provided with the convex clasp nail of interlocking in housing one end, the clasp nail of earmuff housing embeds running through in the shrinkage pool of headband and is embedded on the headband, the rotatable location of earmuff housing, and be provided with the groove that is the relief depression, winter protection in earmuff housing outer rim place, warmingly be coated on above-mentioned earmuff agent structure outermost layer with cloth material sewing.

This shows, its primary structure of this utility model is by an adjustable lock ring ring, two earmuff housings and outer sewing winter protection cloth constitute, the a plurality of ratchets and the snapping point that are provided with by lock ring ring inboard, allow user can adjust the elasticity of frenulum more easily, and in the shrinkage pool and the convex trip of two lock ring rings, one side, make its ringwise the earmuff housing clasp nail of shape can be buckled in the shrinkage pool, and in having, outside upset bending property, and get so that the recessed trench on the earmuff housing is buckled in trip location usefulness, a kind of collapsible use that is easy to carry that places is provided, and can be coated on the ear periphery fully, reach the resisting cold effect of warming.

In sum, the collapsible winter protection earmuff that places of this utility model, utilize the ratchet on the contraction type lock ring ring group and the cooperation of snapping point, the energy life-time service to reach suitable wearing elasticity, and set shrinkage pool and the convex trip of headband root edge, the clasp nail on the cooperation earmuff housing and the design of groove, allow both sides earmuff physical ability be convenient to turn to, locate, arrange in pairs or groups in the peripheral sewing winter protection of structure, the warming cloth material of using, the resisting cold of wearing is for a long time used, promote effect, possessed progressive and practicality more.

Below,, after conjunction with figs. is described in more detail in, make increase to understanding of the present utility model by a preferable feasible embodiment now with regard to structure function of the present utility model.
