Pod rod storage and unfolding device

Abstract

The invention discloses a pod rod storage and unfolding device which comprises a frame, two rollers, an unfolding and folding mechanism, a pod rod and two ring loosening preventing mechanisms. The two rollers are rotatably connected in the frame, the unfolding and folding mechanism is arranged in the frame, the pod rod comprises two omega-shaped shells, one ends of the two omega-shaped shells are fixedly connected to the two rollers respectively. Each roller is internally provided with one ring loosening preventing mechanism, each ring loosening preventing mechanism comprises a first motor, a potentiometer, a torsional spring and a connecting rod; the first motors are fixedly connected to the frame, the potentiometers are fixedly connected to the inner walls of the rollers, output shafts of the first motors are connected with the potentiometers through the connecting rods, one ends of the torsional springs are fixedly connected to the connecting rods, and the other ends of the torsional springs are fixedly connected to the inner walls of the rollers. According to the pod rod storage and unfolding device, the ring loosening preventing mechanisms are arranged in the rollers, so that not only can the ring loosening phenomenon be avoided during the operation of the pod rod, but also the tightening torque of the pod rod can be changed by changing the set angle difference between the first motors and the rollers.

Description

technical field [0001] The invention relates to the field of bean pod pole technology, and more specifically relates to a bean pod pole storage and deployment device. Background technique [0002] The pod rod is a kind of thin-walled composite material support rod that can be rolled up and expanded by its own elastic energy. It is composed of two "Ω" shell structures bonded by glue or Velcro. Within the stress range, winding and retracting can be realized. Because the cross-sectional shape is similar to the "pod" structure, it is called "pod rod". The biggest feature of the pod pole is that it can automatically unfold by relying on the elastic energy stored when it is folded, and can be stored in a small space. It also has the characteristics of ultra-light weight, high bending and high torsional rigidity. At present, the existing pod rod retracting device usually rolls a pod rod directly onto the pod rod roller, and then uses power to unfold or retract the pod rod, so as ...

Problems solved by technology

However, due to the certain thickness of the pod itself, it is very easy to loose the ring due to the recovery force of the pod itself during the curling process, and even cause damage to the pod
