Description
Technical field
This utility model relates to a kind of audition of being convenient to accurate dismounting and detects earplug, particularly a kind of detection earplug that earplug protecgulum, sealing rubber pad and body can be connected by locknut.
Background technology
Along with the development of society, human fertility quality to self, the body constitution of the infant of especially just being born has had higher requirement.Whether each organ of birth back baby's health is healthy normal, caused that society and baby family members more and more pay close attention to.In order can baby's audition to be detected, so that pinpoint the problems early, thereby the baby is carried out appropriate treatment and relief in time, produce the baby and listened force checking device.This checkout gear is formed by detecting earplug and main frame.Whether the medical worker will detect the auditory meatus that earplug is put into the baby, and will output to earplug by the acoustic signals that main frame sends, and subsequently with the input of the feedback signal in baby's auditory meatus main frame, thereby form visible waveform and data, normal to confirm baby's audition.In using the process of listening force checking device, the cerumen in baby's auditory meatus stops up signal delivery outlet and the input hole that detects in the earplug protecgulum through regular meeting.Therefore, need the earplug protecgulum can separate, so that remove the cerumen that is blocked in the earplug with the earplug body.At present, Denmark has produced a kind of baby's audition and has detected earplug, can be separated from each other in order to realize earplug protecgulum and earplug body, and earplug protecgulum (probe) has adopted the assembling mode that clamps structure with the earplug body.But because this structure needs the slideway of earplug protecgulum (probe) to match with the chute of body top, and realizes assembly by the tight mechanism of padlock of body below, so assembly precision and manufacturing process that this assembling and positioning mode requires are all very high.So, there is a need in the field to provide a kind of can being separated from each other easily and detection earplug that manufacture process requirement is lower.
The utility model content
This utility model provides a kind of easy accessibility, is easy to make, and cooperates the earplug of audition detection closely.This earplug has higher quality of fit, can baby's audition be detected.
Detect earplug according to audition of the present utility model and comprise locknut, protecgulum, sealing gasket and body, described audition detects earplug and is characterised in that: described protecgulum and described body cooperatively interact in the mode of groove and projection, thereby make described protecgulum and described body fluid-tight engagement, and clamp described sealing gasket therein; And described locknut can be inserted in described protecgulum from the place ahead of described protecgulum, and is socketed in the outside of described body, thereby described locknut, protecgulum, sealing gasket and body are fused in order.
According to an aspect of the present utility model, have groove on the concave station of the preceding cover back-end of audition detection earplug, have projection on the front end of described body.
According to another aspect of the present utility model, have female thread on the described locknut of audition detection earplug, have external screw thread on the described body, by described female thread and externally threaded the cooperation making described lock sheath be connected on the outside of described body.
According to another aspect of the present utility model, the core that audition detects described protecgulum, described sealing gasket and the described body of earplug has the signal transmission hole respectively.
According to another aspect of the present utility model, the described sealing gasket of audition detection earplug and described protecgulum are bonded with each other in the mode of locating hole and reference column, thereby the signal transmission hole that has respectively on described protecgulum, described sealing gasket and the described body is alignd mutually, and form the passage of sealing.
By above structure, can between locknut, protecgulum, sealing gasket, body, form and have the body that closely combines that connects signal transmission passage, thereby make the detection earplug in the process of repeated disassembled and assembled, can keep its quality of fit and seal request, make things convenient for the test operation of audition.And, because when earplug was dismantled, the opposite spin locknut can be broken assembly to take out the earplug protecgulum and be carried out the cerumen cleaning, therefore makes the maintenance of earplug more simple and convenient.In addition, the manufacturing procedure of earplug with above structure is very simple, has therefore reduced the production cost of earphone.
