Abstract
A bicyclo ring combined, staggered opening use structure piston, the upper edging and the lower edging of each piston ring groove is staggered with a piston ring locating pin, one end face of each piston ring is opened with a locating pin gap, in each piston ring groove, two piston rings located by the piston ring locating pin separately arranged by the upper and the lower edging of the piston ring groove are positioned on the end face opening the locating pin gap of the upper ring upward and the end face opening the locating pin gap of the lower ring downward, the structure is simple, when the piston ring and the engine cylinder abrades and the piston ring opening back-lash augments, still capable of keeping the gas tightness of the cylinder, prolonging the service life of the piston ring and the engine cylinder, reducing the charge for use, also decreasing the time of usage delayed resulted from changing the piston ring or the engine cylinder.
Description
Technical field
The utility model relates to a kind of engine piston, and particularly a kind of dicyclo merges, a mouthful utilization structure piston staggers.
Background technique
Existing piston mostly is a groove one ring structure, be to place a piston ring in each road piston ring groove, such piston, in use because the wearing and tearing of piston ring and cylinder cylinder barrel, piston ring gap can increase gradually, thereby influence the tightness of cylinder, when piston ring gap greater than the regulation limiting value the time, just require to change piston ring, if belong to cylinder barrel serious wear problem, then require to change cylinder barrel, piston ring and cylinder cylinder barrel are short working life, this not only increases cost of use, also can be because of more rering or cylinder cylinder barrel are incured loss through delay use.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiency that the available engine piston exists, and a kind of dicyclo that can prolong piston ring and cylinder cylinder barrel working life merges, a mouthful utilization structure piston staggers and provide.
The technical scheme in the invention for solving the technical problem is: this dicyclo that can prolong piston ring and cylinder cylinder barrel working life merges, a mouthful utilization structure piston staggers, all stagger and respectively establish a piston ring locating stud in the upper edge of its each road piston ring groove and lower edge, offer a locating stud breach on the end face of each piston ring, the end face that all above ring is offered the locating stud breach in each road piston ring groove makes progress, following ring is offered the end face of locating stud breach and is placed the piston ring that two piston ring locating studs that are provided with by lower edge on the piston ring groove are respectively located downwards.
The locating stud breach of offering on the above-mentioned piston ring end face preferably is opened in the opening of piston ring.
Above-mentioned this dicyclo merges, mouthful utilization structure piston that staggers, and piston ring groove can be one or twice; It also can be multiple tracks.
This dicyclo provided by the utility model merges, a mouthful utilization structure piston staggers, simple in structure, when the wearing and tearing of piston ring and cylinder cylinder barrel and after piston ring gap is increased, the tightness that still can keep cylinder, prolonged the working life of piston ring and cylinder cylinder barrel, reduced cost of use, also reduced because of more rering or cylinder cylinder barrel are incured loss through delay the time of use.
Description of drawings
Fig. 1 is for the dicyclo that the utility model embodiment is provided merges, the general structure schematic representation of mouthful utilization structure piston that staggers.
Embodiment
With reference to accompanying drawing, the utility model embodiment is provided, and this dicyclo that can prolong piston ring and cylinder cylinder barrel working life merges, mouthful utilization structure piston that staggers has the twice piston ring groove, all stagger and respectively establish a piston ring locating stud 1 in the upper edge of its each road piston ring groove and lower edge, offer a locating stud breach on the end face of each gap-clearance of piston rings place, the end face that all above ring 21 is offered the locating stud breach in each road piston ring groove makes progress, encircle 22 end faces of offering the locating stud breach down and place two piston ring locating studs (11 that are provided with by lower edge on the piston ring groove respectively downwards, 12) Ding Wei piston ring 2.
Claims (2)
1, a kind of dicyclo merges, a mouthful utilization structure piston staggers, it is characterized in that: all stagger and respectively establish a piston ring locating stud (1) in the upper edge of its each road piston ring groove and lower edge, offer a locating stud breach on the end face of each piston ring, in each road piston ring groove all above ring (21) end face of offering the locating stud breach encircle (22) up and down and offer the piston rings (2) that the end face of locating stud breach is placed two piston ring locating studs (11,12) location that are provided with by lower edge on the piston ring groove respectively downwards.
2, dicyclo merging according to claim 1, mouthful utilization structure piston that staggers, it is characterized in that: the locating stud breach of offering on its piston ring (2) end face is opened in gap-clearance of piston rings place.
