Abstract
The utility model discloses a kind of compressor crosshead and piston rod attachment structure, including crosshead（1）And piston rod（2）, the piston rod（2）Pass through crosshead（1）And be threaded connection, in the piston rod（2）Traversing through end be provided with nut（3）, the nut（3）It is threaded connection mechanism and crosshead（1）Connection.This utility model has smart structural design, with low cost, service-strong advantage, can effectively prevent piston rod from loosening using it, improve the connection reliability of piston rod and crosshead so that compressor operating is stable, and fault rate is low.
Description
Technical field
This utility model is related to a kind of compressor, particularly a kind of compressor crosshead and piston rod attachment structure.
Background technology
At present, within the compressor under small-sized load condition, piston rod and crosshead in reciprocating moving mechanism adopt spiral shell
Stricture of vagina connects.
Utility model content
The purpose of this utility model is just to provide a kind of reliable compressor crosshead of connection and piston rod attachment structure.
The purpose of this utility model realizes that by such technical scheme a kind of compressor crosshead is connected with piston rod
Binding structure, including crosshead and piston rod, the piston rod through crosshead and is threaded connection, in wearing for the piston rod
Go out end and be provided with nut, the nut is threaded connection mechanism and is connected with crosshead.
Wherein, the threaded connection includes the straight-tooth for being arranged on nut back end outer wall and being wholely set with nut,
Be provided with the tooth bar engaged with straight-tooth on the end face of the crosshead, the tooth bar by be located at tooth bar two ends bolt A and
Bolt B is connected with the crosshead end face.
In order to further prevent bolt looseness, on the bolt A and bolt B, it is provided with the 8 of connecting bolt A and bolt B
Font steel wire.
As a result of above-mentioned technical proposal, this utility model has smart structural design, with low cost, service-strong
Advantage, can effectively prevent piston rod from loosening using it, improve the connection reliability of piston rod and crosshead so that compressor
Stable, fault rate is low.
Description of the drawings
Description of the drawings of the present utility model is as follows：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in further detail, but this utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within this utility model
Claim scope required for protection.
Embodiment 1：As shown in figure 1, a kind of compressor crosshead and piston rod attachment structure, including crosshead 1 and piston
Bar 2, the piston rod 2 through crosshead 1 and are threaded connection, and the traversing through end of the piston rod 2 is provided with nut 3, institute
State nut 3 and be threaded connection mechanism and be connected with crosshead 1.
Wherein, above-mentioned threaded connection includes being arranged on the straight-tooth being wholely set on 3 rear end outer wall of nut and with nut 3
4, the tooth bar 5 engaged with straight-tooth 4 is provided with the end face of the crosshead 1, the tooth bar 5 is by being located at 5 two ends of tooth bar
Bolt A6 and bolt B 7 are connected with 1 end face of the crosshead.
In order that bolt connection firmly, prevents bolt looseness, is provided with connection spiral shell on the bolt A6 and bolt B 7
The 8-shaped steel wire 8 of bolt A6 and bolt B 7.
In this utility model, as nut 3 itself has pretightning force, along with being nibbled by tooth between nut 3 and tooth bar 5
Close, with engagement force so that connection is relatively reliable.
