Abstract
The invention relates to a connecting rod connected with a bolt directly. The connecting rod connected with a bolt directly comprises a connecting rod body (1), a large-head cover (2) and a connecting bolt (3); screw holes (4) are symmetrically formed in two sides of a curved shaft hole of the connecting rod body (1); the bolt (3) passes through a through hole in the large-head cover (2) and is connected with the screw holes (4); a polygonal bolt head is provided with through holes (5); steel wires (6) pass through the through holes (5) in two sides of the bolt in a crossed mode, and two end heads of the steel wires (6) are hinged mutually. Because the technical scheme is adopted, the connecting rod connected with the bolt directly, which is provided by the invention, has the advantages of compact structure, simple locking structure, component size reduction, reduction of weight of the connecting rod component, light weight of reciprocating motion elements of a compressor and the like.
Description
Technical field:
The present invention relates to the compressor industry.Be particularly related to the direct-connected connecting rod of a kind of bolt of Reciprocting piston compressor.
Background technique:
Connecting rod is the vitals in compressor, conventional Connecting format is that connecting-rod bolts run through connecting rod shank, the unthreaded hole of skull is fastening by hexagon nut greatly, in order to prevent that the nut pine from moving back, also to increase lock washer or be locked by the mode that slotted nut adds cotter pin, again due to the restriction that is subject to installing space, bolt spins in order to prevent from screwing nut, the head round platform of bolt also will be processed an anti-rotation plane, can make like this bolt head pressure-bearing inequality and produce bias, thereby make bolt be subject to additional flexural stress.
Summary of the invention:
Purpose of the present invention is exactly to be subject to the additional problems such as flexural stress, the direct-connected connecting rod of a kind of bolt provided in order to solve existing compressor connecting bar bolt-locking complex structure and bolt.
To achieve these goals, the present invention has adopted following technological scheme:
The connecting rod that a kind of bolt is direct-connected, it comprises: connecting rod shank, large skull and connecting bolt, the crankshaft hole bilateral symmetry of connecting rod shank is provided with screw, bolt is connected with the screw on connecting rod shank through the through hole of large skull, the polygonal head stage casing of bolt radially is provided with through hole, and steel wire intersects stranded mutually through two ends after the through hole on the bolt of connecting rod both sides.
Described bolt head inner end is provided with a platform, and the diameter of platform is greater than the polygonal size of head.
Described bolt head is made as Shi Erjiao, and its profile coordinates with the plum blossom shaped spanner of same size.
Owing to having adopted technique scheme, make the present invention there is compact structure, the advantage such as locking mechanism is simple, and part dimension reduces, and alleviates linkage component weight, and compressor reciprocating part quality is light.
For more detailed explanation the present invention, following accompanying drawing provides a most preferred embodiment.
The accompanying drawing explanation:
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is that the B of Fig. 1 is to view;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is conventional connecting rod signal;
Fig. 5 is that the A of Fig. 4 is to view.
Embodiment:
As Fig. 1, Fig. 2, shown in Fig. 3, the connecting rod that a kind of bolt is direct-connected, it comprises: connecting rod shank 1, large skull 2 and connecting bolt 3, the crankshaft hole bilateral symmetry of connecting rod shank 1 is provided with screw 4, bolt 3 is connected with screw 4 through the through hole of large skull 2, one side of bolt 3 is provided with a platform, platform plays the effect of plain cushion, the polygonal bolt head middle part in the platform outside radially is provided with through hole 5, through hole 5 follower heads on the bolt head that steel wire 6 intersections screw through the connecting rod both sides are stranded mutually, can prevent that the bolt pine from moving back, the head of bolt can be set as 12 jiaos, its profile coordinates with the plum blossom shaped spanner of same size.By Fig. 4, shown in Fig. 5, the bolt-through connecting rod shank that conventional Connecting format is is round platform by one group of one end and the unthreaded hole of large skull, fastening with being threaded of bolt by hexagon nut, bolt spins in order to prevent from screwing nut, the head round platform of bolt also will be processed an anti-rotation plane, can cause like this bolt head pressure-bearing inequality and produce eccentric, thereby make bolt be subject to additional flexural stress, for preventing that the nut pine from moving back, general adopt lock washer or locked by the mode that slotted nut adds cotter pin, so just make locking mechanism complicated and increased the weight of linkage component.
Owing to having adopted technique scheme, make the present invention there is compact structure, locking mechanism is simple, and part dimension reduces, linkage component weight saving, the advantage such as compressor reciprocating part quality is light.
