Abstract

The utility model discloses a construction of earplug, comprising an outer housing made of flexible material, with openings disposed on the front and rear end, and a rear segment plugged with an inner housing, an inner housing plugged with rear portion of the outer housing, with screw thread disposed inside, a holding unit disposed outside, a plurality of inner housing holes arranged at the front and the rear ends. A part of material of the rear portion of the outer housing is filled in through hole of the inner housing to match with the holding unit, so that the inner housing is closely plugged to the rear portion of the outer housing. The outer housing is plugged to the inner housing, with the front portion in hollow status. When worn on the ears, the hollow portion can reduce contact pressure, so that effect of comfort and durability can be reached when stethoscope is long-term worn.

Description

The earplug structure

Technical field

The utility model relates to a kind of earplug structure, particularly a kind ofly the perforation of several inner housings is set and is provided with stopper in the outside at inner housing, makes it can take into account comfortable and durable a kind of earplug structure.

Background technology

General stethoscope is that medical personnel are when carrying out curative activity, the frequent instrument that uses, with stethoscope contact human body, the sound that sends during by the human internal organs activity, transfer to left and right sides ear via sound conductor, the audio mail of medical personnel to hear, rely on professional knowledge and experience that the situation of human body is done preliminary judgement, therefore, medical personnel need wear stethoscope for a long time, and the earplug quality of contact ears, it is one of principal element of decision comfortableness, so wear down for a long time, remove auscultation weight ， Er ? also bear and reverse and drop-down external force, see also as Fig. 1, shown in Fig. 1-1, traditional ear plug of stethoscope 4 is in order to be closely tied in stethoscope conduit two ends, and its earplug inside is provided with internal thread 41 and material is comparatively hard, contacts ears for a long time and then can cause the pain discomfort.

Though comfort level has improvement greatly now, see also shown in Fig. 2, Fig. 2-1,

Leading portion is in order to the soft shell body 5 of quality softness, the screw shell 51 that the chimeric material of back segment is harder, though improved the comfortableness of using, but pull through external force, the damage that just gets loose easily of the joint of soft shell body 5 and screw shell 51 has reduced useful life of earplug, holds the defective of above-mentioned existing earplug structure, not enoughly satisfy now medical personnel etc.. user's demand is demanded further improvement urgently.

The utility model content

The purpose of this utility model is, by a kind of earplug structure is provided, makes it can take into account functions such as comfortable and durable.

The utility model is to adopt following technological means to realize:

A kind of earplug structure of the utility model, housing front end and rear end all are provided with several inner housing perforation within it, the outside is provided with stopper, and inside thread can cooperatively interact with the two ends of stethoscope sound guide tube, shell body is made with soft material, when shell body in forming process, be packed into the inner housing perforation with the part material, and cooperate stopper that shell body and inner housing is closely chimeric, make the shell body leading portion be hollow, wear when ears because its hollow part can cooperate various ear type indents to slow down contact pressure, again the part material is packed into the inner housing perforation and cooperates stopper.

A kind of earplug structure of the utility model, chimeric position is difficult for damaging when the earplug structure is subjected to external force and pulls, and reaches to have functions such as comfortable and durable concurrently.

Embodiment

Below in conjunction with accompanying drawing specific embodiment of the utility model is illustrated:

A kind of earplug structure of the utility model sees also as Fig. 3～shown in Figure 6, and primary structure comprises formations such as shell body 1 and inner housing 2, wherein;

See also as shown in Figure 5, inner housing 1 inboard is provided with screw thread 11, the outside is provided with stopper 12, front end and rear end are provided with inner housing perforation 13, shown in Fig. 3, Fig. 3-1, shell body 2 with the part material of shell body back segment 22, is filled in inner housing perforation 13 in forming process, cooperate stopper 12 to make inner housing 1 and the 22 tight chimeric moulding of shell body back segment.

The earplug structure is incorporated into stethoscopic conduit two ends with screw thread 11, compare with traditional earplug, shell body back segment 22 is packed into inner housing perforation 13 with the part material, therefore the telescoping part damage that also can not get loose when external force is pullled sees also as shown in Figure 6, and shell body leading portion 21 is because of being hollow state, so when shell body leading portion 21 contact ears, wherein the vacancy changes along with the ear radian, reduces the pressure of earplug structure and ears, thereby reaches comfortable durable function.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
