Abstract
The utility model discloses a two ring piston combination which comprises a piston body and a piston rod, wherein the piston body is connected with the piston rod; the piston body is provided with piston ring clamping grooves; an upper piston ring and a lower piston ring are arranged in the piston ring clamping grooves; the upper piston ring is provided with an upper piston ring opening, and the lower piston ring is provided with a lower piston ring opening; the piston rod comprises a rod body; the front part of the rod body is connected with an elastic rod; and the elastic rod is provided with a flange. Both of the piston ring clamping grooves of the piston body are provided with the upper piston ring and the lower piston ring, and the openings of the upper piston ring the lower piston ring are mutually dislocated, so that the phenomena of air leak, flame-over and engine oil combustion can be avoided when the piston body reciprocates in the cylinder sleeve; and thus, the utility model enhances the output power of the internal combustion engine, lowers the noise, has the advantages of simple structure and low cost, is easy to manufacture, and is suitable for various internal combustion engines.
Description
Technical field
The utility model relates to a kind of piston, is specially a kind of two ring piston combination, belongs to mechanical field.
Background technique
As everyone knows, piston is in internal combustion engine cylinder jacket in the reciprocating process, and is should sliding effect good, and seal action is arranged again, owing between piston and the cylinder sleeve certain interval being arranged, this will lean on the piston ring on the piston to be sealed.On the existing piston mostly be whenever-piston ring is installed in the individual piston ring groove, and an opening is arranged on each piston ring, piston is when the compression work done like this, pressurized gas in the cylinder sleeve are then by the opening on first piston ring, enter the interval of first piston ring and second piston ring, and then form gas leakage, alter fiery phenomenon by the opening on second piston ring; And piston is in breathing process, and the machine oil around the piston then is inhaled into the firing chamber along above-mentioned passage, has produced burning machine oil phenomenon, makes thus that output power of internal combustion engine reduces, noise increases.
The model utility content
For the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of two ring piston combination is provided, and solved internal-combustion engine gas leakage, alters fire, the problem of burning machine oil, reduced noise, improved the output power of internal-combustion engine.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of two ring piston combination, comprise piston only and piston rod, piston only is connected with piston rod, be provided with the piston ring draw-in groove on its piston only, be provided with upper piston ring and lower piston ring in the piston ring draw-in groove, be provided with the upper piston ring opening on the upper piston ring, be provided with lower piston ring opening on the lower piston ring; Be provided with the bayonet socket suitable with upper piston ring opening and lower piston ring opening in the described piston ring draw-in groove; Described piston rod comprises shaft, and the shaft front portion is connected with elastic rod, is provided with flange on the elastic rod.
Optimize above-mentioned two ring piston combination, the setting of mutually staggering of its upper piston ring opening and lower piston ring opening.
Optimize, above-mentioned two ring piston combination is provided with shoulder between its shaft and the elastic rod, and shoulder is provided with chamfering.
Optimize, above-mentioned two ring piston combination, the quantity of its flange is 3-6, is provided with thrust ring in the flange.
The utility model is because employing is installed piston ring and lower piston ring in each piston ring draw-in groove of piston only, and make the opening mutual dislocation of upper piston ring and lower piston ring, therefore it can prevent gas leakage that piston only produces during to-and-fro motion, alter fiery phenomenon and burning machine oil phenomenon in cylinder sleeve, therefore improved the output power of internal-combustion engine, and the reduction noise, simple in structure, easy making, with low cost, be adapted at using on the various internal-combustion engines.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Further set forth technical characterstic of the present invention below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, the utility model is a kind of two ring piston combination, comprise piston only 1 and piston rod 2, piston only 1 is connected with piston rod 2, be provided with piston ring draw-in groove 3 on its piston only 1, be provided with upper piston ring 4 and lower piston ring 5 in the piston ring draw-in groove 3, be provided with upper piston ring opening 41 on the upper piston ring 4, be provided with lower piston ring opening 51 on the lower piston ring 5; Be provided with the bayonet socket 31 suitable with upper piston ring opening 41 and lower piston ring opening 51 in the described piston ring draw-in groove 3; Described piston rod 2 comprises shaft 21, and shaft 21 front portions are connected with elastic rod 22, are provided with flange 221 on the elastic rod 22.The setting of mutually staggering of upper piston ring opening 41 and lower piston ring opening 51.Be provided with shoulder 23 between shaft 21 and the elastic rod 22, shoulder 23 is provided with chamfering.The quantity of flange 221 is 3-6, is provided with thrust ring 222 in the flange 221.
The utility model is because employing is installed piston ring and lower piston ring in each piston ring draw-in groove of piston only, and make the opening mutual dislocation of upper piston ring and lower piston ring, therefore it can prevent gas leakage that piston only produces during to-and-fro motion, alter fiery phenomenon and burning machine oil phenomenon in cylinder sleeve, therefore improved the output power of internal-combustion engine, and the reduction noise, simple in structure, easy making, with low cost, be adapted at using on the various internal-combustion engines.
Above demonstration and described basic principle of the present utility model and major character and advantage thereof.The technology personage of the industry should understand; the utility model is not subjected to the restriction of above-mentioned implementing regulations; what describe in above-mentioned implementing regulations and the specification is to be used for illustrating principle of the present utility model; under the prerequisite that does not break away from the utility model principle and scope; the utility model also can have various changes and modifications, and these changes and improvements all belong in claimed the utility model scope.
The claimed scope of the utility model defines with appending claims and other equivalent.
