It is preferred that described back-up ring includes the internal diameter mistake of interconnective head and bar portion, described bar portion and described piston pin It is full of cooperation, the internal diameter matched in clearance of described head and described through hole.
It is preferred that described bar portion is also hollow structure, and bar wall is provided with the groove that at least two is axially disposed, described Groove runs through whole described bar portion.
It is preferred that groove described at least two is uniformly arranged on described bar wall.
It is preferred that described head is one-body molded with described bar portion.
It is preferred that described head and the flush with outer surface of described piston.
It is preferred that described piston pin ferrum is made, described back-up ring uses nylon material to make.
It is preferred that the outer surface of described piston is provided with the ring groove that three roads are circumferentially arranged, divide in described ring groove It is not provided with sealing ring.
Compared with prior art, the air compressor piston that this utility model provides, inserts described piston including piston and one end Interior connecting rod, is respectively equipped with, in described piston and in described connecting rod, the through hole run through, and a piston pin passes described through hole, described work Plug pin is the cylinder of inner hollow and both ends open, described piston pin be respectively arranged at two ends with back-up ring.In this utility model, two Individual back-up ring can stop piston pin movement vertically, it is ensured that piston and the connection of connecting rod, and without offering groove at internal piston, The most there is not the risk that jump ring pin comes off in piston, thus improve the safety that piston uses, extend the use of piston Life-span.
Accompanying drawing explanation
Fig. 1 is the structural representation of the air compressor piston of this utility model one detailed description of the invention.
In figure: 10-piston, 11-through hole, 12-annular groove, 13-sealing ring, 20-connecting rod, 30-piston pin, 40-back-up ring, 41-head, 42-bar portion, 43-groove.
Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this The detailed description of the invention of utility model is described in detail.It should be noted that, this utility model accompanying drawing all uses the form of simplification And all use non-ratio accurately, only in order to purpose convenient, aid illustration this utility model embodiment lucidly.
The air compressor piston that this utility model provides, as it is shown in figure 1, include that piston 10 and one end are inserted in described piston 10 Connecting rod 20, is respectively equipped with the through hole 11 run through in described piston 10 and in described connecting rod 20, a piston pin 30 is through described logical Hole 11, described piston pin 30 is the cylinder of inner hollow and both ends open, described piston pin 30 be respectively arranged at two ends with back-up ring 40.In this utility model, two back-up rings 40 can stop piston pin 30 movement vertically, it is ensured that piston 10 and the company of connecting rod 20 Connect, and without offering groove inside piston 10, the most there is not jump ring pin and come off the risk in piston 10, thus improve work The safety that plug uses, extends the service life of piston.
It is preferred that please continue to refer to Fig. 1, described back-up ring 40 includes interconnective head 41 and bar portion 42, it is preferred that institute State head 41 one-body molded with described bar portion 42, make simple, be connected firmly.Wherein, described bar portion 42 and described piston pin 30 Internal diameter interference fit, the internal diameter matched in clearance of described head 41 and described through hole 11.Live it is to say, described bar portion 42 inserts The hollow bulb of plug pin 30, it is achieved back-up ring 40 is connected with the fixing of piston pin 30, meanwhile, head 41 and through hole 11 matched in clearance, just Maintenance in back-up ring 40 is dismantled or is changed.It addition, described head 41 and the flush with outer surface of described piston 10, it is ensured that outward appearance is whole Clean, and operator can according to outward appearance judge back-up ring 40 whether with piston pin 30 compact siro spinning technology, if head 41 highlights piston 10 Outer surface, then need be adjusted or change parts.
It is preferred that please continue to refer to Fig. 1, the bar portion 42 of described back-up ring 40 is also hollow structure, and bar wall is provided with at least Two axially disposed grooves 43, described groove 43 runs through whole described bar portion 42, in the present embodiment, the number of described groove 43 Amount is two, and two grooves 43 are uniformly arranged on described bar wall, so, during making, can be done by the external diameter in described bar portion 42 Must be more than the internal diameter of piston pin 30, when back-up ring 40 is inserted piston pin 30, bar portion 42 is due to the effect of groove 43, to contract, While convenient installation, bar portion 42 can further ensure that back-up ring 40 to the inwall of piston pin 30 with sufficiently large support force and live Plug pin 30 compact siro spinning technology, does not comes off.
It is preferred that described piston pin 30 is made with ferrum, it is ensured that piston pin 30 can provide enough hardness and abrasion resistance;Institute Stating back-up ring 40 uses nylon material to make, good springiness and when contacting with piston pin 30 and piston 10, using the teaching of the invention it is possible to provide enough frictions Power.
