Spring has a wide range of uses and is almost an indispensable part of ordinary machines. It will elastically deform under the action of external force, store deformation energy and release it randomly. Coil springs among spring types refer to springs that rely on torsional elasticity to transmit force or motion to generate friction. A spring that relies on the elasticity of the coil spring to generate friction to transmit power or motion. However, the traditional coil spring exists when the structural strength is low, the torque is small, the stability is poor, and the force is large.
The following technical solution is provided: a coil spring including a circular arch connection and a defined inner rod. The ends of the arc-shaped connecting rods are all fixed by springs. The outer end of the spring body is fixed as a connecting rod. A limit lever is provided on one side of the connecting rod. Slides are installed on both sides of the inner wall of the limit rod. The end of the inner rod of the limit rod is A baffle is installed, and the limiting inner rod is provided with a baffle.
The dome-shaped connecting rod, spring body, connecting rod and mounting hole are connected together by a single structure, all made of rod-shaped steel materials.
The spring entity has the same dimensions as the spring entity, the center lines coincide, and the number of revolutions of the spring entity is at least two rotations.
Whether the inner diameter of the limiting sleeve is 0.2 mm or 0.5 mm larger than the diameter of the limiting inner rod, and whether the diameter of the deflector is 0.1-2 larger than the inner diameter of the limiting sleeve.
Effects and advantages: The coil spring is installed at a fixed point with the mounting hole using screws, so that the coil spring has high stability during use and is not easy to slip. If the dome link is pulled at an angle, and the dome link needs to maintain this position, this can be improved by limiting the inner rod to slide within a limiting sleeve rod, and then fixing the dome link by limiting the stopper at the end of the inner rod. Torsional force of double torsion spring. The dome-shaped connecting rod, spring body, connecting rod and mounting hole are connected together in a single structure, all made of a bar-shaped steel material, which increases the structural strength of the coil spring and reduces the deformation of the coil spring. The spring and spring body have the same size, the center lines coincide, and the number of coils is at least two wheels, so the force is uniform and the torque of the spring body can be increased. The coil spring is more stable and has a longer service life.
