Description

Ear muff

(1) technical field

This utility model relates to a kind of life health care articles for use, the specifically ear muff that a kind of winter, winter protection was used.

(2) background technology

In general, ear muff is as the winter protection in winter.The tradition ear muff is made of the connecting rod or the rubber connecting strip made by the synthetic resin material of two ear lids and engaging lug lid.Wear ear muff, can effective warming ear, avoid the hardship of cold injury.

But, but there is following defective in the ear muff structure that ear lid and connecting rod form one: the area that integral body takies is bigger, when not using, can take big quantity space, and carry extremely inconvenient, in addition, different user also needs the ear muff of buying different size according to the shape and the size of self head; There are the following problems and ear covers the ear muff structure that links together with rubber connecting strip: though easy to carry, when wearing, rubber connecting strip can be oppressed head, and when using for a long time, user has the sensation of significant discomfort.

In order to adjust the connecting rod length of engaging lug lid, the external existing ear muff patented technology that can adjust length, this ear muff is can prolong the connecting rod two ends to form most hooks and meet, and ear lid is assembled in hook meets, promote to adjust the position then up and down, user can be adjusted, still according to the shape and the size of self head, this method is just in order to keep the form of connecting rod, merely the height of ear lid is adjusted,, can be strutted semicircular connecting rod if when the user head is excessive, can oppress the user head when wearing, bring sense of discomfort, when using for a long time, also can bring out some bad problems.Generally speaking, the structure of ear muff should satisfy following 3 points: first is should not bring constriction to the head of user when using for a long time; Second is can effectively adjust length according to the shape and the size of user head; Easy to carry when thirdly being to use.

(3) summary of the invention

Technical assignment of the present utility model is at the deficiencies in the prior art, even a kind of long-time use is provided, also can not bring constriction, according to the shape and the size of user head to the head of user, can effectively adjust length, and when not using ear muff easy to carry.

The technical scheme that its technical problem that solves this utility model adopts is:

Ear muff of the present utility model is made by synthetic resin, comprise the semicircle connecting rod and the Er Gai that make by the synthetic resin material, two connecting rod left-right symmetric, the medial end of two connecting rods forms the support portion with assembly hole respectively, two mutual reciprocal insertions of connecting rod, length direction according to a lateral connector bar forms protuberance, about forming on the assembly hole that inserts the opposite side connecting rod, adjust the support component of the protuberance of connecting rod, the outboard end of connecting rod is provided with the ear lid that entangles ear's size by hinged joint, and the outside of the ear lid at semicircle connecting rod and its two ends is wrapped with enclosing cover.

The outer end of above-mentioned connecting rod forms protuberance respectively, and Dui Ying ear covers the draw-in groove that correspondence forms and protuberance matches therewith.

Ear muff of the present utility model compared with prior art, the beneficial effect that is produced is:

This ear muff can suitably be adjusted according to the head of user, thus bring constriction can not for when wearing ear muff the head of user, and can effectively adjust length according to wearer's nose shape and size.The ear lid can also rotate freely, and the ear muff volume after folding is very little, can be convenient for carrying.

Among the figure, 10, connecting rod, 10 ', connecting rod, 12, the support portion, 13, assembly hole, 15, protuberance, 16, support component, 17, protuberance, 18, draw-in groove, 20, the ear lid, 20 ', the ear lid, 22, hinged joint, 30, enclosing cover.

(5) specific embodiment

Explain below below in conjunction with accompanying drawing 1-5 ear muff of the present utility model being done.

Shown in accompanying drawing 1-5, ear muff of the present utility model, its structure be two

semicircle connecting rods

10,10 making by synthetic resin ' and the

ear lid

20,20 at its two ends ' and wrap connecting rod 10,10 ' and ear lid 20,20 ' enclosing cover 30 constitute.

Above-mentioned connecting rod 10 and 10 ' about cut apart formation accordingly, connecting rod 10 and 10 ' medial end form the support portion 12 of assembly hole 13 can reciprocal insertion assembling, one lateral connector bar 10 forms protuberance 15 according to the direction of length, the opposite side connecting rod 10 that connecting rod 10 inserts ' assembly hole 13 form the protuberance 15 corresponding support protuberances 16 of adjusting the length of connecting rod about supporting, connecting rod 10 and 10 ' outside form can reverse fold the ear that is connected by hinged joint 22 cover 20.

Above-mentioned connecting rod 10,10 ' and ear lid 20,20 ' the have restorative elasticity in recessed to the inside back.

Above-mentioned connecting rod 10,10 ' the outside form protuberance 17, corresponding ear lid 20,20 ' on form protuberance 17 accordingly, the draw-in groove 18 of insertion can prevent the generation of the bow tie of ear lid.

When wearing ear muff of the present utility model, at first, will according to the nose shape of user and size can about adjust connecting rod 10,10 ', to above-mentioned left and right sides connecting rod 10,10 ' carry out length adjustment by the external force left and right directions, a lateral connector bar 10 protuberances 15 and opposite side connecting rod 10 ' the supporting projections portion 16 that forms of assembly hole 13 adjust adjusting on the position.

The certain length of connecting rod 10,10 ' keep when not adding external force, can simply adjust length by external force, user according to the shape of head and big I effectively adjust connecting rod 10,10 ' state, above-mentioned connecting rod 10,10 ' and ear lid 20, the open state of 20 ' lateral direction under wear.

Above-mentioned ear lid 20,20 ' when being enclosed within the ear, connecting rod 10,10 ' put at the head rear.Wearing when going out, above-mentioned connecting rod 10,10 ' and the restorative elastic force in ear lid 20,20 ' to the inside recessed backs can keep the state of wearing.

Above-mentioned connecting rod 10,10 ' according to the shape and the size of user head, its length can about freely adjust, so the dynamics of compressing head remains unchanged when wearing.

Even the head of user is excessive, also can pass through foregoing, adjust compressing power separately to head.So when wearing, sensation as snug as a bug in a rug.

Above-mentioned wear with ear lid under the state 20,20 ' a side bayonet slot 18 on insert connecting rod 10,10 ' protuberance 17 states that block open laterally, so above-mentioned ear lid 20,20 ' can about replace and wear.

As mentioned above, when needs are carried, utilize external force that connecting rod 10,10 ' opposite direction is kept and minimized length, ear lid 20,20 ' with the hinged joint is the eclipsed state of center steering, and is reduced in size as much as possible, so very convenient to carry.

At this moment the open laterally external force of ear lid 20,20 ' do not add, thus from the draw-in groove 18 of a side break away from easily connecting rods 10,10 ' protuberance 17, and can turn round, folding ear lid 20,20 '.

Its processing and fabricating of ear muff of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.

Except that the described technical characterictic of description, be the known technology of those skilled in the art.
