Description
Technical field
The utility model relates to the adjustable power of the determining pull bar of a kind of pulling force, belongs to field of mechanical technique.
Background technique
Pull bar is the conventional component in the field such as machine-building, vehicle transport.A lot of occasions of pull bar application are all fixing, without the need to regulating pulling force.But at some special occasions, require that the pulling force of pull bar is adjustable or fixing, at this moment common pull bar can not meet usage requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of pulling force the adjustable power of determining pull bar, its structure is simple, easy to operate, cheap, the use occasion that the draw-bar pull that can meet the demands is adjustable or fixing.
The purpose of this utility model is achieved in that the adjustable power of the determining pull bar of a kind of pulling force, it comprises the leading portion body of rod, leading portion Screw-thread sealing plug, sleeve, mid-section threads end socket, the stage casing body of rod, turnbuckle and tail rod body, the described leading portion body of rod is connected by spring with one end of the stage casing body of rod, the other end of the described stage casing body of rod inserts one end of turnbuckle, locking is screwed by stage casing outer-hexagonal nut, turnbuckle is inserted in one end of described tail rod body, locking is screwed by outer-hexagonal nut, the described leading portion body of rod and the stage casing body of rod are provided with leading portion Screw-thread sealing plug and mid-section threads end socket respectively by bearing pin, described sleeve is arranged between leading portion Screw-thread sealing plug and mid-section threads end socket.
Compared with prior art, the beneficial effects of the utility model are:
The stage casing of the present utility model body of rod and tail rod body screw thread are respectively left-handed and dextrorotation, when rotating turnbuckle along a direction, the stage casing body of rod and tail rod body are regained simultaneously or are released, when determine power pull bar two ends fixing after, rotate turnbuckle, the i.e. amount of tension of adjustable springs, namely regulates the pulling force determining power pull bar; Connecting thread between turnbuckle and the stage casing body of rod, tail rod body adopts self-locking thread, regulate when determining power draw-bar pull, namely after turnbuckle position is fixed, outer-hexagonal nut is screwed to turnbuckle direction, make to produce enough pretightening forces between turnbuckle and the stage casing body of rod, the back segment body of rod, turnbuckle position is fixed, namely ensures the tensions constant determining power pull bar; By spring fitting within sleeve, play a protective role to spring, the pull bar preventing spring breaking down from causing is determined power and is forbidden.
Accompanying drawing explanation
Fig. 1 is a kind of pulling force of the utility model adjustable power of determining bracing structure figure.
Fig. 2 is the enlarged view at I place in Fig. 1.
