Abstract
A kind of compressor crosshead piston rod of present invention offer and cap anti-loosing device, it includes：Crosshead（1）, in crosshead（1）One end is equipped with interconnecting piece（2）, in piston rod（3）It is equipped with simultaneously cap（3a）, in simultaneously cap（3a）With interconnecting piece（2）Between be equipped with corresponding matching fixture block（4）, it is characterised in that：In described and cap（3a）Outer wall be equipped with one circle convex block, on convex block periphery be equipped with convex block sawtooth（3b）；Pressing plate is set（5）, pressing plate（5）Side be equipped with and convex block sawtooth（3b）The pressing plate sawtooth of corresponding matching（5a）, the pressing plate（5）With fixture block（4）Pass through screw（4a）Connection.The configuration of the present invention is simple, it is easy to use, can directly be transformed on existing, effectively avoid and the case where cap loosens.
Description
Technical field：
Specifically it is exactly a kind of compressor crosshead piston rod and cap is anti-the present invention relates to a kind of compressor safety device
Release.
Background technology：
Piston compressor in operation process, air-breathing/exhaust alternately, compressor transmission parts crosshead and piston
Bar connecting portion often will appear on piston rod and cap loose phenomenon under the action of alternating force, cause transmission parts by
Shock causes crosshead damage, piston rod, fixture block broken or piston slap cylinder head portions, is brought to compressor safe operation
Certain hidden danger.
Invention content：
The present invention is exactly to provide a kind of compressor crosshead piston rod and cap is locking to overcome deficiency in the prior art
De- device.
The present invention provides following technical scheme：
A kind of compressor crosshead piston rod and cap anti-loosing device, it includes：Crosshead is equipped in crosshead one end and connects
Socket part, connection piston rod again on interconnecting piece, piston rod is equipped with and cap, and the folder of corresponding matching is equipped between cap and interconnecting piece
Block, it is characterised in that：It is equipped with a circle convex block on described and cap outer wall, convex block sawtooth is equipped on convex block periphery；Setting
Pressing plate is equipped with the pressing plate sawtooth with convex block sawtooth corresponding matching in the side of pressing plate, and the pressing plate is connected with fixture block by screw
It connects.
Based on the above technical solution, there can also be technical solution further below：
In setting one and fixture block and the reinforcing sleeve of interconnecting piece corresponding matching, it also is provided with and screw on reinforcing sleeve
The through-hole of corresponding matching.
The pressing plate is that arc-shaped and described pressing plate sawtooth is arranged on the intrados of pressing plate.
Invention advantage：
The present invention have many advantages, such as it is simple in structure, easy to use, can directly be transformed on existing, especially by
And the mode that sawtooth and pressing plate sawtooth are mutually twisted is set on cap outer wall, it avoids and cap rotates loosen on the piston rod
Phenomenon occurs.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode：
As shown in Figure 1, a kind of compressor crosshead piston rod and cap anti-loosing device, it includes：Crosshead 1, in cross
First 1 one end is equipped with interconnecting piece 2, is equipped with and is turned over all over portion 2a in 2 one end of interconnecting piece.One end of piston rod 3 is connected in interconnecting piece 2.
The mode being connected through a screw thread on the shaft of piston rod 3 is socketed with tubular and cap 3a, and cap 3a and interconnecting piece 2 turn over all over portion
The fixture block 4 of corresponding matching is equipped between 2a.
It is equipped with a circle convex block on the outer wall of fixture block 4 one in described and cap 3a, it is convex that a circle is equipped on convex block periphery
Block sawtooth 3b.
The pressing plate 5 of a pair of of arc is set, pressing plate sawtooth 5a is equipped on the intrados of 5 inside of pressing plate.The pressing plate saw
Tooth 5a and convex block sawtooth 3b corresponding matchings.By being mutually twisted for pressing plate sawtooth 5a and convex block sawtooth 3b, effectively avoid simultaneously
Cap rotates the case where loosening on the piston rod due to being acted on by alternate stress.
One package fixture block 4 is being set and is turning over the reinforcing sleeve 6 all over portion 2a.The reinforcing sleeve 5, interconnecting piece turn over
It is connected and fixed by screw 4a all over portion's 2a fixture blocks 4 and pressing plate 5.
