Description
Technical field:
This utility model relates to a kind of double end rustless steel stethoscope.
Background technology:
Stethoscope is the important tool that medical personnel carry out curative activity, and by stethoscopic sound amplification function, user can be recognized the situation of the patient's that sees a doctor internal organs.Stethoscope is to be collected by the operational sound that can will the person's of seeing a doctor internal organs to amplify, and is passed to the ear of user again via listening tube, earplug.
At present, the stethoscope that the doctor uses is inconvenient to change can in use, and hearing effect is bad, exists to leak the sound phenomenon.In addition, not hear the movable sound of the person's of seeing a doctor internal organs, user must firmly be pushed stethoscope tin, thereby has increased the working strength of user, has increased the person's of seeing a doctor misery.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, provide a kind of simple in structure, strengthen tightness, strengthen rotating the double end rustless steel stethoscope of comfortableness.
The purpose of this utility model realizes through following technical scheme: a kind of double end rustless steel stethoscope, be provided with first through hole and second through hole of horizontally set in the can, and first through hole and second through hole communicate; The inside of can is step; Be inserted with in the can and listen bar, listen the third through-hole that is provided with vertical setting in the bar, listen an end of bar to be inserted between first through hole and second through hole in the can; A side of listening bar that is inserted in the can has chadless; Chadless communicates with first through hole or second through hole, and the periphery, top of can is with sealing ring, spring, dead axle from top to bottom successively, and sealing ring, spring, dead axle are located at respectively in the step of can; Listen the middle part outer race of bar to be useful on the fixing positioning sleeve of listening bar, dead axle and spring; One end of positioning sleeve is inserted in the can, listens the periphery, bottom of bar to be with pvc pipe, is provided with fourth hole in the pvc pipe.
The further improvement of this utility model is: the front end of can is provided with diaphragm through the winter protection circle.
The further improvement of this utility model is: listening the bottom of bar is the back-off inclined-plane that is used to connect said pvc pipe.
This utility model compared with prior art has the following advantages: this utility model utilizes air conveying principle, as bearing medium, dust in the workshop is transported to the device of specified local centralized collection, processing with air (or other gases such as nitrogen etc.).The high efficiency of this utility model is cleaned widely, has alleviated workman's work, and safe in utilization, health can not work the mischief to the healthy of workman.
Description of drawings:
Fig. 1 is the exploded view of this utility model;
Fig. 2 is the cutaway view of this utility model;
Label among the figure: 1-can, 2-listen bar, 3-sealing ring, 4-spring, 5-dead axle, 6-positioning sleeve, 7-PVC pipe, 8-winter protection circle, 9-diaphragm, 10-first through hole, 11-third through-hole, 12-chadless, 13-fourth hole, 14-second through hole.
The specific embodiment:
In order to deepen understanding to this utility model, will combine embodiment and accompanying drawing that this utility model is done further to detail below, this embodiment only is used to explain this utility model, does not constitute the qualification to this utility model protection domain.
Show the stethoscopic a kind of embodiment of this utility model double end rustless steel like Fig. 1 and Fig. 2; Comprise can 1; First through hole 10 and second through hole, 14, the first through holes 10 and second through hole 14 that are provided with horizontally set in the can 1 communicate, and the inside of can 1 is step; Fix a tin bar, dead axle, spring on can with positioning sleeve 6, belong to the stethoscope main part; Be inserted with in the can 1 and listen bar 2, listen the third through-hole 11 that is provided with vertical setting in the bar 2, listen an end of bar 2 to be inserted between first through hole 10 and second through hole 14 in the can 1; A side of listening bar 2 that is inserted in the can 1 has chadless 12; Chadless 12 communicates with first through hole 10 or second through hole 14, and the periphery, top of can 1 is with sealing ring 3, spring 4, dead axle 5 from top to bottom successively, and sealing ring 3, spring 4, dead axle 5 are located at respectively in the step of can 1; Dead axle 5 is assemblied in stethoscope tin inside; Cooperate with a tin bar waveform face, the cover riveted joint that is positioned fixes and can inside, and one side is by can step surface pressing spring in addition; Spring 4 is assemblied in can inside, makes dead axle behind the compressional deformation and listens bar to have certain activity space to rotate, and reaches the mutual commentaries on classics of clock face and face; Behind spring deformation, sealing ring is pushed, block can and listen the gap that produces between the bar, reach sealing effectiveness; Listen the middle part outer race of bar 2 to be useful on the fixing positioning sleeve 6 of listening bar 2, dead axle 5 and spring 4; One end of positioning sleeve 6 is inserted in the can 1; Listen the periphery, bottom of bar 2 to be with pvc pipe 7, be provided with fourth hole 13 in the pvc pipe 7, the front end of can 1 is provided with diaphragm 9 through winter protection circle 8.Listening the bottom of bar 2 is the back-off inclined-plane that is used to connect pvc pipe 7, and listening bar 2 is exchange auditions of realizing face and clock face with rotating.
When the chadless in listening bar communicated with first through hole in the can, second through hole was plugged, and user hears it is to pass the sound of coming in first through hole; Rotation can or listen 180 ° on bar, listen in the bar chadless just with can in second through hole communicate, first through hole is plugged, user hears it is the sound that biography is come in second through hole.This utility model has been strengthened the tightness of double end rustless steel stethoscope self and the comfortableness of rotation having used new structure aspect fixing and the rotation.
This utility model has at first well solved the processing problems of can, and it is very simple that can processing becomes, and next has improved the difficult problem of assembling, and this utility model spring and steel ball in assembling have fixed, so need not consider the elastic force that produces; Hearing effect is better than existing product, because sealing ring is arranged, two holes do not produce interference, makes outside sound can not pass fully in the hole that is communicated with in the stethoscope into, so hearing effect is better.
