Groove 52 is plug-in with the T-shaped plush copper 72 of the second connecting rod 7 being arranged on bent axle 4, then by jump ring 6 along the axle of bent axle 4
Insert from top to bottom between the first step portion of described T-shaped plush copper 72 and the second step portion of described T-shaped groove 52 to direction
In gap, thus complete assembling.
As can be seen here, owing to link assembly uses split-type structural, the structure overcoming the existence of existing unitary link is multiple
Miscellaneous, mould molding difficulty, assemble troublesome problem；And compared with existing Split connecting rod assembly, the embodiment of the present invention is provided
Two parts connecting rod of piston compressor link assembly use T-shaped plush copper and T-shaped groove 52 to coordinate, and by keeper by T-shaped
Plush copper and T-shaped groove 52 connect fastening, need not process the groove for jump ring 6 plug-in mounting, and therefore structure is simpler, and easy mould becomes
Type, and assemble convenient.
Embodiment two
As shown in Figure 6,7, the structure substantially phase of the structure of the link assembly of the present embodiment and the link assembly of embodiment one
With, difference is: the front end face 721a of described T-shaped plush copper 72 is V-arrangement, groove bottom 521a of described T-shaped groove 52 be with
The V-arrangement that the front end face 721a of described T-shaped plush copper matches.The front end face 721a of T-shaped plush copper and groove bottom 521a of T-shaped groove 52
Being V-arrangement face so that first connecting rod 5 and second connecting rod 7 are big in the effect lower stress face of jump ring 6, laminating is tighter, with crankshaft operation
Time more stable.
Embodiment three
As shown in Figure 8,9, the structure of the link assembly of the structure of the link assembly of the present embodiment and embodiment one, two is substantially
Identical, difference is: the front end face 721a of described T-shaped plush copper 72 is V-arrangement, and groove bottom 521a of described T-shaped groove 52 is
The V-arrangement matched with the front end face 721a of described T-shaped plush copper, meanwhile, the notch of described T-shaped groove 52 is V-arrangement, described second
The V-arrangement cooperation face 73 that the wall 53 with described notch matches it is provided with on two opposite flanks of connecting rod 7.So first connecting rod
5 and second connecting rod 7 coordinated by two groups of V-arrangement faces and more can guarantee that first connecting rod 5 and second connecting rod 7 stablizing during assembling
Property, makes link assembly more stable when with crankshaft operation, and, such stress surface is bigger, it is to avoid due to stress surface too small and
Make V-arrangement facial disfigurement so that the hidden danger that comes off of jump ring 6.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
