Description
Technical field
The utility model and a kind of piston ring.
Background technology
Piston ring is a kind of band annular seal jaggy, and static element is pushed against by elasticity possessed after being held together by pressure
Inner hole wall on seal.Piston ring of the prior art there is a situation where to be not easy clamping and gas leakage.
Utility model content
In order to solve above-mentioned prior art problem, the utility model provides a kind of piston ring, can improve more than not
Foot.
The utility model is related to a kind of piston rings, and including ring body, there is the ring body open type to take mouth, and two relatively freely
End end is connected together；A specific free end has half-sectional opening, and the opening has vertical plane and cambered surface, in vertical plane
The bayonet of setting wedge shape is stayed in inside setting, and conical surface clamp is set in cambered surface and bayonet adjacent position；Another free end set with
Be open matched lug；The lug contacts setting card in side with vertical plane, and cone slot card eye is being set with cambered surface contact position；
The ring body inner cover stays setting annular groove, and the annular groove inner wall is inclined outwardly forms dovetail groove with slot bottom；It is set positioned at slot bottom
Sticky bed course, sets sealing ring on bed course, and the sealing ring is in close contact with annular groove；Slag is deposited in the ring body surface setting
Slot.
Further, setting balance mounting hole in the ring body.
Further, the balance fixed hole position is in ring body trisection posistion.
Further, the bayonet inner wall setting soft magnetosphere.
Further, ring body link position is directed toward at the tip of the bayonet.
The utility model is ingenious in design, and there is provided the leakproofness that sealing ring increases ring body, and there is provided bayonets and conical surface card
Son, conical surface clamp and cone slot card eye increase the compactness that piston ring connects.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is free end structure diagram in Fig. 1.
Fig. 3 is a-a ' enlarged drawings in Fig. 1.
Diagram：1 ring body, 2 sealing rings, 3 balance mounting holes, 4 lugs, 5 openings, 6 bayonets, 61 cards, 62 soft magnetospheres, 7 cones
Slag chute is deposited in face clamp, 8 cone slot card eyes, 9 sticky bed courses, 10 annular grooves, 11.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of piston ring, including ring body 1, there is the ring body 1 open type to take mouth, and two opposite
Free end end is connected together；A specific free end has half-sectional opening 5, and the opening 5 has vertical plane and cambered surface,
The bayonet 6 of setting wedge shape is stayed in setting on the inside of vertical plane, and soft magnetosphere 62 is set in 6 inner wall of bayonet.In cambered surface and 6 adjacent position of bayonet
Conical surface clamp 7 is set；Another free end is set and 5 matched lugs 4 of opening；The lug 4 contacts side with vertical plane and sets
Card 61 is put, cone slot card eye 8 is being set with cambered surface contact position；1 inner cover of ring body stays setting annular groove 10, as shown in figure 3,
Its 10 inner wall of intermediate annular groove is inclined outwardly forms dovetail groove with slot bottom；Sticky bed course 9 is set positioned at slot bottom, is set on bed course close
Seal 2, sticky bed course increase the stability of its connection, and sealing ring 2 is in close contact with annular groove 10；The ring body surface setting is used
In storage rub cut clast deposit slag chute 12；Piston ring in use when in the presence of because generating tiny the asking of cutting of rubbing during reciprocating friction
Topic, so as to affect the cleannes of product enables the cleannes of hydraulic oil destroy, can be cut by depositing slag chute 12 to rubbing simultaneously
The storage of clast, preventing clast from friction occurs with ring body causes to wear.
It is directed toward ring body link position in the tip of the bayonet.
In order to facilitate the installation of, the setting balance mounting hole 3 in ring body 1, balance mounting hole 3 are located at 1 trisection posistion of ring body.
Ring body main body use stainless steel, the card set on lug and cone slot card eye and matching opening and
Conical surface clamp and bayonet in opening increase the stability of the engaging of ring body, and the sealant of setting increases leakproofness, can
Avoid gas leak phenomenon.
