Weight running parcel reverse action eliminating back frame

Abstract

The invention relates to a weight running parcel reverse action eliminating back frame, and discloses a back frame which performs damping offset on movement of the bag body by utilizing the combined action of spiral magnetized stripes and an elastic rope. The back frame is characterized in that: a fixed frame is arranged over a bottom support plate, one ends of two guide rods are respectively arranged on the bottom support plate, the other ends are respectively arranged on the fixed frame, the guide rods are vertically placed, spiral magnetized stripes are arranged on the surface of the guiderods, two guide tubes respectively sleeve on the two guide rods; the spiral magnetized stripes are arranged on the inner walls of the guide tubes, with the magnetism opposite to that of the spiral magnetized stripes on the surface of the guide rods; the spiral magnetized stripes on the inner walls of the guide tubes are intersected with the spiral magnetized stripes on the surface of the guide rods, two limiting rings respectively sleeve on the two guide rods and are respectively located above corresponding guide tubes, fastening screws are arranged on the limiting rings, one ends of two mainbody tubes are respectively arranged at two ends of the bottom support plate, and the other ends respectively penetrate out upwards from the fixed frame.

Description

technical field [0001] The invention relates to a back frame for canceling the reverse action of a load-carrying package, which relates to a back frame for canceling the reverse force of carrying a package during a human body's load-bearing movement, and belongs to the field of logistics and transportation. In particular, it relates to a back frame which utilizes the combined action of a spiral magnetized strip and an elastic cord to buffer and counteract the movement of the bag body. Background technique [0002] At present, in outdoor activities, daily life, logistics and distribution, etc., it is necessary to carry the weight through the backpack, and place the items in the backpack for easy carrying and storage. However, when the existing backpack is carried, the body and the shoulder strap are integrated. , in the process of moving, the body of the bag will jump up and down with the step frequency of the human body, and the body of the bag will be slapped on the waist o...

Problems solved by technology

[0002] At present, in outdoor activities, daily life, logistics and distribution, etc., it is necessary to carry the weight through the backpack, and place the items in the backpack for easy carrying and storage. However, when the existing backpack is carried, the body and the shoulder strap are integrated. , in the process of moving, the body of the bag will jump up and down with the step frequency of the human body, and the body of the bag will be slapped on the waist or buttocks, which will increase the burden on the waist and buttocks. , in the process of moving, not only will it form an impact on the human body, but also collisions will occur between the packages in the package, which will affect the delivery of the packages. In some urgent situations, it is necessary to run. The step frequency changes, the turbulence of the package increases, and the impact on the human body increases, which affects the balance of the human body and is prone to fall, etc., and the inertia of the package during the movement causes the acceleration of the package to change, thereby increasing The pressure on the shoulders can easily cause shoulder injuries and other problems
