Description
Technical field
The present invention relates to goods setting tool technical field in the logistics transportation, especially relate to a kind of rigid force-measuring tensioner.
Background technology
In the process that goods betransported, Goods binding need be lived usually, to prevent that goods from coming off or to collide mutually and cause and lose or damage.Strainer is a kind of advanced person's a binding tools, adopts not only convenient but also safety of strainer restraint of loads, is subjected to the welcome of vast chaufeur deeply.For strainer is improved, people have carried out long-term exploration, have proposed various improvement projects.
Chinese patent CN2827932Y " the lever fastener " that provide for example, it is made up of mobile jib, U type bar and lock iron etc., mobile jib is zigzag, the inner of mobile jib is hinged on the U-shaped open end of U type bar, in the time of Goods binding need being lived, move mobile jib and make the zigzag protrusion place of mobile jib be rocked to the bottom of U type bar from the top of U type bar.End at U type bar is connected with bundling belt, and the other end of bundling belt is connected in the protrusion place at mobile jib middle part.The bundling belt that is connected in protrusion place, mobile jib middle part during with Goods binding can be along with the bottom that together is rocked to U type bar.Though above-mentioned patent can make bundling belt tighten up after pulling mobile jib, thereby Goods binding is lived.Above-mentioned strainer can't be known the situation of bundling belt tensile force, is difficult to during use control.Usually can cause bundling tension goods is caused damage, bundling belt fracture, perhaps can impact goods transport because binding is tight inadequately.
In addition, when restraint of loads, all can there be difference in the dynamics when binding in different positions for various goods or identical goods, and this has just increased the difficulty of controlling by manually more.If each strainer is all controlled respectively, obviously waste time and energy.In addition, in transportation, owing to jolt, reason such as vibrations may cause the bundling belt tensile force of each strainer to change, some local bundling belt tensile force is excessive, the local bundling belt tensile force of some is too small again.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of and can in time know strainer tightening force size, safe, and compact conformation, the rigid force-measuring tensioner of low cost of manufacture.
