Spring is a kind of mechanical parts utilizing elasticity to carry out work, under external force deformation occurs with the part that elastic material is made, and restores to the original state again after removing external force.Therefore along with the fast development of industrial age, spring is more and more used in various elastic component, makes the function of various mechanical device more powerful, uses convenient.Different springs has the limit of different Tension and Compression, and when spring is in ultimate state for a long time, the elasticity coefficient of spring will be affected, and even causes the damage of spring.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides a kind of and can change different springs, and can arrange the coil tension spring device of maximum tension length and minimum compressed length.
In order to achieve the above object, the technical solution of the utility model is:
A kind of coil tension spring device, comprise the first flexible rod and be socketed in the second flexible rod outside described first flexible rod, one end away from described second flexible rod offers the first outside thread with described first flexible rod, described first flexible rod is movably installed with the first fixed base by the first outside thread, on described first fixed base, clamping is provided with the first fixed plate, and described first flexible rod is also movably installed with the first set screw nut by the first outside thread; One end away from described first flexible rod offers the second outside thread with described first flexible rod, described second flexible rod is movably installed with the second fixed base by the second outside thread, on described second fixed base, clamping is provided with the second fixed plate, and described second flexible rod is also movably installed with the second set screw nut by the second outside thread; Be provided with the first spring between described first fixed plate and the second fixed plate, the two ends of described first spring are fixedly mounted on described first fixed plate and the second fixed plate respectively.
The bottom surface of described second flexible rod inside is installed with the second spring, the other end of described second spring is installed with dunnage.
It is inner that described dunnage is movably arranged on described second flexible rod, and the shape of described dunnage is identical with the shape of described second flexible rod internal cross section.
One end that described first flexible rod and the second flexible rod socket-connect offers the first engagement portion and the second engagement portion respectively.
Described first fixed base is identical with the external diameter of described second fixed base, and described first fixed plate is also identical with the external diameter of described second fixed plate.
The beneficial effects of the utility model are: a kind of coil tension spring device of the present utility model, and the first engagement portion and the second engagement portion limit the maximal dilation length of the first flexible rod and the second flexible rod, thus the maximum tension length of restraining spring; Second spring of the second flexible rod inside and dunnage limit the maximum compression length of the first flexible rod and the second flexible rod, and have and have buffer function, thus protection spring can not be impaired because being subject to excessive compression.First fixed plate and the second fixed plate can from dismounting and change the first fixed base and the second fixed base, and the first spring also can be changed according to different demand.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
