Description
Technical field
The utility model relates to plant equipment part field, specifically a kind of pull bar.
Background technology
Pull bar is used on case and bag mostly, and part pull bar is used in plant equipment.Be used in the pull bar in plant equipment, when stressed, because foundry machine part is more crisp, pull bar in use can bend, and causes the difference in length between pull bar, even ruptures, have impact on normal work widely, service life is shorter, and some pull bar existence is simultaneously connected underaction with plant equipment, uses problem not easily.
Utility model content
The purpose of this utility model is the defect overcoming above-mentioned prior art, provides a kind of structure simple, long service life, pull bar easy to use.
The technical solution of the utility model is achieved in that a kind of pull bar, comprise bar body, a described next body adopts a metal material to make, it comprises the front end connecting portion connected successively, middle part extension section and tail end lift portion, described connecting portion is made up of conical and cylinder, described cylinder offers the rectangular through-holes that runs through whole cylindrical sidewall, described middle part extension section comprises interior bar and outer bar, described outer bar is set on described interior bar, described interior bar front end outer wall is arranged protruding elastic clamping block, accordingly, the sidewall of described outer bar offers the draw-in groove that described elastic clamping block established by card, the described tail end portion of lifting offers the groove for connecting draw ring.
Preferably, described in lift portion diameter be less than the diameter of described interior bar, the diameter of described interior bar be less than the diameter of described outer bar.
Preferably, described cylindrical diameter is less than the diameter of described outer bar.
The beneficial effects of the utility model are: overall structure is simple, and it adopts metal to make, easy to process, sound construction, makes pull bar mechanical strength high, not easy fracture, substantially increases the service life of pull bar; Meanwhile, the utility model sidewall offers the draw-in groove that described elastic clamping block established by card, the described tail end portion of lifting offers the groove for connecting draw ring, is connected with plant equipment, easy to use.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram (phantom) of a kind of pull bar of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, concrete case study on implementation of the present utility model is illustrated:
As described in Figure 1, a kind of pull bar, comprise bar body, described bar body adopts metal material to make, it comprises the front end connecting portion 1 connected successively, and middle part extension section 2 and tail end lift portion 3, and described connecting portion 1 is made up of conical and cylinder, described cylinder offers the rectangular through-holes 4 that runs through whole cylindrical sidewall, described bar body can be connected with plant equipment by described rectangular through-holes 4.Described middle part extension section 2 comprises interior bar 21 and outer bar 22, and described outer bar 22 is set on described interior bar 21, by stretching and shrinking described interior bar, effectively can regulate the length of whole middle part extension section 2.Particularly, described outer bar 22 is provided with manhole 9, for connecting exterior mechanical equipment, described interior bar 21 front end outer wall arranges protruding elastic clamping block 5, accordingly, described outer bar 22 inwall sidewall on offer the draw-in groove 6 and protruding 8 that described elastic clamping block established by card, described elastic clamping block 5 can be fastened in described draw-in groove 6, for fixing described interior bar 21, described protruding 8 withstand on described elastic clamping block 5, accordingly, being provided with protruding outer bar sidewall is elastic portion, pin described elastic portion inwardly to extrude described protruding 8 and described elastic clamping block 5 can be extruded in described draw-in groove 6, then described interior bar 21 can be pulled.Going out to be provided with block 10 in the outlet of described outer bar 22, for blocking elastic clamping block 5, avoiding described interior bar 21 to be drawn out from outer bar 22.Described tail end lifts portion 3 and offers groove 7 for connecting draw ring, and described draw ring is arranged in described groove 7, pulls described draw ring that described interior bar 21 can be driven to slide in described outer bar 22.
Preferably, described in lift portion 3 diameter be less than the diameter of described interior bar 21, the diameter of described interior bar 21 is less than the diameter of described outer bar 22.Described cylindrical diameter is less than the diameter of described outer bar 22.Particularly, described in lift portion 3 diameter be 18mm, the diameter of described outer bar is 22mm, and described cylindrical diameter is 12mm.
The beneficial effects of the utility model are: overall structure is simple, and it adopts metal to make, easy to process, sound construction, makes pull bar mechanical strength high, not easy fracture, substantially increases the service life of pull bar; Meanwhile, the utility model sidewall offers the draw-in groove that described elastic clamping block established by card, the described tail end portion of lifting offers the groove for connecting draw ring, is connected with plant equipment, easy to use.
As described above, be only preferred embodiment of the present utility model, when can not limit the scope of the utility model enforcement with this, namely the simple equivalence change generally done according to the utility model claim and utility model description with modify, all still belong in scope that the utility model patent contains.
