Description

earplug structure

technical field

The utility model relates to an earplug structure, in particular to an earplug structure in which several inner casing perforations are arranged on the inner casing and a catch is provided on the outer side, so that the earplug structure can be comfortable and durable.

Background technique

The general stethoscope is a tool often used by medical staff when performing medical work. The stethoscope touches the human body, and the sound emitted by the internal organs of the human body is transmitted to the left and right ears through the sound guide. The sound information heard by the medical staff, Rely on professional knowledge and experience to make a preliminary judgment on the condition of the human body. Therefore, medical staff need to wear stethoscopes for a long time, and the quality of earplugs that touch both ears is one of the main factors that determine comfort. However, long-term wear Next, in addition to the weight of auscultation, the ear also bears the external force of twisting and pulling down. Please refer to Figure 1 and Figure 1-1. In order to closely fit the two ends of the stethoscope tube, the traditional stethoscope earplug 4 has an internal thread inside the earplug 41 The material is relatively hard, and long-term contact with the ears will cause pain and discomfort.

Although the comfort level has been greatly improved nowadays, please refer to Figure 2 and Figure 2-1.

The front section is used for the soft shell 5, and the rear section is fitted with the hard threaded shell 51. Although the comfort in use is improved, the joint between the soft shell 5 and the threaded shell 51 will be damaged after being pulled by an external force. It is easy to get loose and damaged, which reduces the service life of the earplugs. Due to the above-mentioned defects of the existing earplug structure, it is not enough to meet the needs of users such as current medical staff and so on, and further improvement is urgently needed.

Utility model content

The purpose of the utility model is to provide an earplug structure that can take into account functions such as comfort and durability.

The utility model is realized by adopting the following technical means:

The utility model relates to an earplug structure, in which several inner shell perforations are arranged at the front end and the rear end of the inner shell, and a clamp is arranged on the outside, and the inner thread can cooperate with the two ends of the sound guide tube of the stethoscope, and the outer shell has Made of soft material, when the outer shell is in the molding process, part of the material is filled into the perforation of the inner shell, and the outer shell and the inner shell are tightly fitted together with the clamp, so that the front part of the outer shell is hollow, when worn on both ears Because of its hollow part, it can cooperate with various ear-shaped concaves to reduce the contact pressure, and also fill part of the material into the inner shell perforation to match the clip.

The utility model relates to an earplug structure. When the earplug structure is pulled by an external force, the fitting part is not easy to be damaged, so as to achieve the functions of comfort and durability.

Detailed ways

The specific embodiment of the utility model is described below in conjunction with accompanying drawing:

The utility model is an earplug structure, please refer to Fig. 3 to Fig. 6, the main structure includes an outer shell 1 and an inner shell 2, among which;

Please refer to Figure 5, the inner shell 1 is provided with threads 11, the outer shell 12 is provided, and the front and rear ends are provided with inner shell perforations 13, as shown in Figure 3 and Figure 3-1, the outer shell 2. During the molding process, part of the material of the rear section 22 of the outer casing is filled into the inner casing through hole 13, and the inner casing 1 and the rear section 22 of the outer casing are tightly fitted together to form by cooperating with the clip 12.

The earplug structure is combined with the two ends of the stethoscope's conduit by threads 11. Compared with traditional earplugs, the rear part 22 of the outer shell is partially filled into the perforation 13 of the inner shell, so when the external force is pulled, the fitting part will not be loosened and damaged. Please refer to As shown in Figure 6, the front section 21 of the outer casing is hollow, so when the front section 21 of the outer casing touches the ear, the hollow space changes with the curvature of the ear, reducing the pressure on the earplug structure and the ears, thus achieving comfortable and durable Function.

Finally, it should be noted that: the above embodiments are only used to illustrate the utility model rather than limit the technical solution described in the utility model; therefore, although the description has described the utility model in detail with reference to the above-mentioned various embodiments, Those of ordinary skill in the art should understand that the utility model can still be modified or equivalently replaced; and all technical solutions and improvements that do not depart from the spirit and scope of the utility model should be covered by the claims of the utility model among.
