Abstract

The utility model provides an engine failure stethoscope, comprising a round shaped sound cavity (2), a shock sheet (3), a probe (4), a rubber hose (8), and a medical stethoscope. The shock sheet (3) is horizontally fixed in the round shaped sound cavity (2); the probe (4) through a small hole at the center point on the bottom of the sound cavity (2) is vertically fixed; the shock sheet (3) is contacted with the upper end of the probe (4); the rubber hose (8) is connected with a sound outlet on the upper cover of the sound cavity (2); the rubber hose (8) is connected with the medical stethoscope. The utility model has the advantages of simple structure, easy fabrication, low cost, convenient operation, high utilization rate, and long service life. The utility model can be used to checkout equipment at any moment and detect failure in time to avoid loss, which is a necessary tool for the equipment maintaining and servicing.

Description

Engine failure stethoscope

The utility model relates to a kind of abort situation that can accurately determine in engine and other equipment operation, and judges a kind of utensil of its trouble unit and damaged condition.

Motor car engine and other equipment often break down in long-term operation, again because fault mostly in inside, can't see, can only hear unusual sound, therefore do not determine location of fault or parts, so that be easy to delay the time of maintenance, caused unnecessary loss.Sometimes fault is just sent out, and can not listen unusual sound from the sound that running is sent, and has often missed the Maintenance machine meeting, also can cause parts damages.

The purpose of this utility model is to provide a kind of simple engine failure stethoscope; can be often in the running of engine and miscellaneous equipment or detect with it when starting shooting at every turn; can find the hidden danger of parts in time, keep in repair in advance, turn round normally to guarantee engine or equipment.

The utility model is made up of a circular sound chamber, a circular vibrating plate, a probe, one section sebific duct and a common stethoscope.Wherein vibrating plate is horizontally fixed in the sound chamber, and probe is fixed through sound chamber bottom centre place's aperture, and its upper end contacts with vibrating plate is vertical, connects a sebific duct on the loam cake sound mouth of sound chamber, and the latter receives on the common stethoscope (not drawing among the figure).

The utility model is simple in structure, make easily, cost is low, and is easy to use, can check engine or miscellaneous equipment in the running at any time with it, can in time find fault, fault was eliminated before accident takes place, avoided engine and other equipment to cause damage, improved the utilization factor of engine miscellaneous equipment, and prolonging its life-span, it is the indispensable instrument of scheduled maintenance such as engine maintenance.

Structure of the present utility model is provided by following embodiment and accompanying drawing.

Accompanying drawing is to cut open according to the engine failure stethoscope structure that the utility model proposes to show synoptic diagram.

Below in conjunction with description of drawings according to stethoscopic details of engine failure and the operating position that the utility model proposes.

This fault stethoscope has a circular sound chamber (2), it is made up of chamber lid and cavity, both are fixed together by screw thread, and the vibrating plate (3) that the usefulness high-quality steel disc of circle is made is horizontally fixed on the stopping table of sound chamber (2), and the center is porose at the bottom of the chamber, and screw thread is arranged on the hole wall, probe (4) is through this hole, and vertically be fixed up by nut (5), plain cushion (6) and spring shim (7), its upper end contacts with vibrating plate (3), and its exposure level is adjustable; Sebific duct (8) is connected on the sound mouth of sound chamber (2) lid, its common stethoscope of another termination; Handle (1) is an one with the loam cake in sound chamber (2).

When using the utility model, stethoscopic earphone is placed in the ears, hand-held handle (1), allow the probe of probe (4) contact with the engine that will check or each part of miscellaneous equipment lightly, in certain sequence, check the position of each important rapid wear, for example bearing, copper sheathing, bearing shell, gear drive etc., each different parts sends different sound in the running, the sound size is all different with frequency, this can judge by rule of thumb that if some parts of engine are subjected to damage to a certain degree, it will send unusual sound of movement.These normal and abnormal sound can both pass to vibrating plate (3) by probe (4), and pass on the stethoscope through sound mouth, sebific duct (8), send the position of abnormal sound and reach the purpose of checking fault in order to judgement.

Claims
