Abstract
The utility model discloses a kind of slip-knot pull bar, its drip irrigation device is: comprise loop bar and be separately positioned on two drag link bodies at loop bar two ends, described loop bar hollow, and inwall is provided with screw thread, described drag link body comprises draw ring and screw rod, described screw rod coordinates with loop bar inner thread, described loop bar is provided with adjusting portion, adjusting portion can be the direction plane or the through hole that are arranged on loop bar surface, such setting can facilitate screwing of loop bar, thus the convenient relative position regulating loop bar and screw rod, reach the convenient object regulated.
Description
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to a kind of slip-knot pull bar.
Background technique
Slip-knot pull bar is that one end is fixed, the other end is provided with draw ring, be flexibly connected with miscellaneous part by draw ring, it is local that this structure is useful in some hinged grades, by the connection of slip-knot bolt and loop bar, formed and be flexibly connected chain, relatively rotating thus regulating the position of slip-knot bolt by slip-knot bolt and loop bar, and then the position connected is changed, and slip-knot bolt of the prior art is all connect the larger or heavier object not easily rotated often, therefore be all by the rotation of loop bar in general adjustment process and then be socketed its relative position, because loop bar is cylindric, screw in the process of adjustment harder, therefore the adjustment of slip-knot draw rod positions is unfavorable for.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of slip-knot pull bar that loop bar can be facilitated to screw.
For achieving the above object, the utility model provides following technological scheme: a kind of slip-knot pull bar, comprise loop bar and be separately positioned on two drag link bodies at loop bar two ends, described loop bar hollow, and inwall is provided with screw thread, described drag link body comprises draw ring and screw rod, and described screw rod coordinates with loop bar inner thread, and described loop bar is provided with adjusting portion.
The utility model is set to further: described adjusting portion is made up of the through hole that loop bar is arranged, described through hole central axis and loop bar central shaft rectangular.
The utility model is set to further: described adjusting portion is made up of the square face being arranged on loop bar surface.
The utility model is set to further: described screw rod is provided with nut.
The utility model is set to further: be provided with connecting rod between described draw ring and screw rod.
Compared with prior art, the utility model by arranging adjusting portion on loop bar, thus can make directly to be screwed by adjusting portion when adjustment by adjusting portion, thus screwing of loop bar can be facilitated, and then make the relative position of drag link body and loop bar can by loop bar screw thus adjusted, do not need rotating rod body to regulate, further by arranging through hole as adjusting portion, insert through hole by adopting a bar to screw, this set makes loop bar easily screw, and the difficulty that can be screwed by the difference of the length of bar screwed is different, and can insert through hole by a pin after fixation makes slip-knot pull bar whole fixing, thus make its using scope more wide, when regulator site square face, can be regulated by spanner, screw rod arranges nut, this set can make to be locked by nut between screw rod and loop bar, thus its displacement can not be changed again, thus can not make in use can cause some accidents because displacement changes, the setting of connecting rod is for the buffering between draw ring and screw rod, does not need to use screw thread, therefore arrange the processing that connecting rod can reduce reach, thus decrease production cost to a certain extent because general in the place of draw ring.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model embodiment;
Fig. 2 is the structural drawing of the utility model embodiment;
Fig. 3 is the sectional view of the utility model embodiment.
Reference character: 1, loop bar; 11, inwall; 12, through hole; 2, drag link body; 21, draw ring; 22, connecting rod; 3, nut.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model slip-knot pull bar embodiment is described further.
As shown in Figure 1 to Figure 3, a kind of slip-knot pull bar, comprise the loop bar 1 of hollow structure and be separately positioned on two drag link bodies 2 at loop bar 1 two ends, two ends all arrange drag link body 2 and can make this slip-knot pull bar can as active connection, loop bar 1 inwall 11 is provided with screw thread, drag link body 2 comprises draw ring 21, the connecting rod 22 of screw rod and connection draw ring 21 and threaded stem, the setting of connecting rod 22 is for the buffering between draw ring 21 and screw rod, do not need in the place of draw ring 21 to use screw thread because general, therefore the processing that connecting rod 22 can reduce reach is set, thus decrease production cost to a certain extent, screw-thread fit in screw rod and loop bar 1, screw rod is provided with nut 3, this set can make to be locked by nut 3 between screw rod and loop bar 1, thus its displacement can not be changed again, thus can not make in use can cause some accidents because displacement changes, loop bar 1 is provided with the adjusting portion for conveniently screwing loop bar 1, adjusting portion can be arranged to through hole 12, also the direction surface structure identical with nut 3 side face can be arranged to, by the setting of the adjusting portion of through hole 12 or square face, loop bar 1 is easily screwed, and then make the relative position of drag link body 2 and loop bar 1 can by loop bar 1 screw thus adjusted, rotating rod body 2 is not needed to regulate, the adjusting portion of through hole 12 structure can also be inserted through hole 12 by a pin after fixation and make slip-knot pull bar whole fixing, thus make its using scope more wide.
Preferably, loop bar 1 inside is provided with some oil grooves, when inside is stuck time, can add lubricant oil from through hole 12 position, enters loop bar 1 inner, thus reaches the object of lubrication screw thread, its frictional force is diminished by oil groove, thus easy removal.
Described through hole 12 can setting at an angle with loop bar 1, angle between 0 ° to 180 °, be arranged on 30 ° all good to 150 °, vertical axis is set to optimal selection, this set can be conducive to the use of screwing tool, and fixing step after adjustment.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
