Description
Technical field
It the utility model is related to chest expander field, more particularly to a kind of new positive and negative use chest expander.
Background technology
In motor and centrifugal pump servicing operations, lubricating oil is filled to bearing in some cycles and be maintained or more
Change, need to use chest expander that bearing is left behind from axle in bearing replacing, existing chest expander after once bearing is left behind,
Needing solid dog collar being moved back to starting point can just be continuing with, it is necessary to do a large amount of idle works.
Utility model content
The utility model is directed to deficiencies of the prior art, there is provided and it is a kind of time saving and energy saving, put forward efficient one kind
It is new positive and negative to use chest expander.
The purpose of this utility model is to be achieved through the following technical solutions：
It is a kind of it is new it is positive and negative use chest expander, including rotating bar, hook, connecting plate, consolidate dog collar, fixing bolt, described turn
Symmetrical spacing section of lever both sides, spacing section of outside have hexagonal turning end, have cone-shaped plug, light in the middle part of hexagonal turning end
There is shaft end cone tank, in cone-shaped plug insertion axle end toper groove, the solid dog collar inside has internal thread through hole, institute inside axle
Stating in the middle part of rotating bar has threaded rod, and threaded rod is threadedly coupled with internal thread through hole, hexagonal turning end insertion spanner endoporus, rotates
Spanner, internal thread through hole drive axial movement of the solid dog collar in threaded rod, and spacing section provides spacing, hook end pair for solid dog collar
Claim distribution corpus unguis, corpus unguis bottom has pawl head, and Bearing inner has brearing bore, and corpus unguis is inserted in brearing bore, pawl head and axle
Hold inner ring cooperation.
Connection column is uniformly distributed outside the solid dog collar, connecting has column endoporus inside column, in the connecting plate
The symmetrical connecting plate endoporus in portion, fixing bolt are inserted in connecting plate endoporus and column endoporus, fixing bolt and fixing nut spiral shell
Line is connected, and connecting plate is connected with solid dog collar, has hook connecting hole in the middle part of hook, and fixing bolt inserts hook connecting hole with being connected
In plate endoporus, connecting plate is connected with hook, and the Bearing inner is uniformly distributed bearing roller.
Beneficial effect：
Internal thread through hole and shaft, after fixed in cone-shaped plug insertion axle end toper groove, hexagonal turning end is inserted
Entering the rotation of spanner endoporus can allow solid dog collar to drive hook to extract bearing, will when solid dog collar moves to the rotating bar other end
Hook is hauled out from brearing bore, you can work next time is carried out, it is time saving and energy saving without solid dog collar is moved back into starting point, and improve
Efficiency, corpus unguis is symmetrical in hook both sides, and its direction is consistent, after once bearing is pulled out, direct use, and user
Just, it is time saving and energy saving, efficiency is improved, rotating bar both ends are respectively provided with hexagonal turning end and cone-shaped plug, both can be with the axle in optical axis
End toper groove coordinates, and can be rotated again with spanner, facilitate worker to use, time saving and energy saving, improves efficiency.
