Detailed description of the invention
Fig. 1 is cross-sectional view of the invention；
Fig. 2 is use state of the invention with reference to figure.
Specific embodiment
Piston ring suitable for automobile engine as depicted in figs. 1 and 2, the first ring 1 including structure annular in shape, with
And it is nested in the second ring 2 in the first ring 1；
It is provided with the dovetail groove 4 being recessed inwardly on the outer peripheral surface of second ring 2, is provided on the inner peripheral surface of the first ring 1 outward
The trapezoid block 5 of protrusion, the trapezoid block 5 are nested in dovetail groove 4, and spring 3, spring are equipped between trapezoid block 5 and dovetail groove 4
3 one end is connected on trapezoid block 5, and the other end of spring 3 is connected on dovetail groove 4.
The trapezoid block 5 and the setting annular in shape of dovetail groove 4.
Angle between two inclined-planes of the trapezoid block 5 is 61 degree to 64 degree, the folder between two inclined-planes of dovetail groove 4
Angle is 56 degree to 59 degree；That is, the angle between the top surface and bottom surface of trapezoid block 5 is 61 degree to 64 degree, the top of dovetail groove 4
Angle between face and bottom surface is 56 degree to 59 degree.
The spring 3 is helical spring or flat spring.
Detection module, warning module and control module are installed, the detection module is mounted on spring on the trapezoid block 5
Junction between 3 one end and trapezoid block 5, the control module are mounted in trapezoid block 5, and the warning module is mounted on
The outer surface of one ring 1, the pressure of trapezoid block 5 is given by one end that detection module can detecte spring 3.So as to know
One end of spring 3 falls off either with or without from trapezoid block 5.
It is electrically connected between the detection module, warning module and control module, so that detection module, warning module and control
Mutual signal transmitting can be carried out between molding block.
The detection module is pressure sensor, and the brand manufacturers of the pressure sensor is Britain Druck, the pressure
The marque of sensor is PDCR 42.81.200 micro pressure sensor.
The pressure of trapezoid block 5 is given in one end of the detection module detection spring 3, and is converted into corresponding pressure signal,
Pressure signal is sent to control module by the detection module, and the control module receives pressure signal and converted, if
The information of received pressure signal representative be that give the pressure of trapezoid block 5 be zero for one end of spring 3, then the control module root
Pre-warning signal is converted into according to the received pressure signal of institute；If received pressure signal representative information be spring 3 one end
The pressure for giving trapezoid block 5 is greater than zero, then the control module is converted into safety signal according to the received pressure signal of institute, described
Pre-warning signal or safety signal are sent to warning module and carry out early warning by control module, pass through detection module detection spring 3
One end give the pressure of trapezoid block 5, if the pressure that trapezoid block 5 is given in one end of spring 3 is zero, it is known that spring 3
It falls off from trapezoid block 5；If one end of spring 3 give trapezoid block 5 pressure be greater than zero, it is known that spring 3 not from

The warning module is LED light, and pre-warning signal is sent to LED light and controls LED light progress by the control module
It sends out a warning, gives a green light alternatively, safety signal is sent to LED light and controls LED light by the control module, extraneous people can
With by observing LED light, it can be found that whether one end of spring 3 is directly contacted with trapezoid block 5, if extraneous
People can observe that red light is bright, then it can be found that one end of spring 3 is not carried out with trapezoid block 5 by observing LED light
Directly contact；If extraneous people can observe green light, then it can be found that the one of spring 3 by observing LED light
End has directly to be contacted with trapezoid block 5.
In use, take above-mentioned two pieces of piston rings, after its notch is staggered, a piston ring groove 6 being mounted on piston 7
In, spring 3 is in compressive state at this time, and the outer peripheral surface of the first ring 1 is withstood on the inner wall of cylinder 8, and the first ring 1 pushes up the second ring 2
To 6 side wall of piston ring groove, it is tightly attached to the inner peripheral surface of the second ring 2 on 6 side wall of piston ring groove, to make piston ring and piston ring groove
Sideshake between 6 is close to zero, on the other hand, since trapezoid block 5 is embedded in dovetail groove 4, force the two sides up and down of dovetail groove 4 to
The top and bottom of piston ring groove 6 squeeze, to make back clearance between piston ring and piston ring groove 6 close to zero.Therefore, this hair
The bright sideshake cut off between piston ring and piston ring groove 6 and back clearance channel avoid cylinder 8 and generate carbon deposit.
In the middle and later periods of engine operation, if piston ring is worn, i.e. the outer peripheral surface of the first ring 1 is worn, bullet
Spring 3 can stretch automatically, push the outer peripheral surface of the first ring 1 to outside, so that it is withstood the inner wall of cylinder 8, thus to piston ring scuffing
Automatic compensating action is played, avoids cylinder pump oil, spark plug is stained with the failures such as oil, carbon deposit.
The configuration of the present invention is simple can be cut off the sideshake between piston ring and piston ring groove and back clearance channel, avoid cylinder
Carbon deposit is generated, compensating action is played to piston ring scuffing.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
