Problems solved by technology

The applied force includes the gravity of the load and the acceleration of shaking. The greater the range of movement of the load, the greater the value of its acceleration, and thus the greater the force exerted by the load on the shoulders, which greatly increases the pressure on the shoulders. Moreover, during people's actions, the backpack will not only shake up and down, but also shake sideways, which has poor stability and will increase the discomfort of the backpacker.

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] like figure 1 , 2 As shown, a field back frame includes a second bracket 2 , a strap 4 and a backrest 5 . The second bracket 2 is longitudinally provided with a central axis 10 , the upper and lower ends of the central axis 10 are fixedly connected to the second bracket 2 , and the central axis 10 is located at the center of the second bracket 2 in the width direction.

[0049] The front side of the second bracket 2 is provided with a first bracket 1 movably connected with the second bracket 2 . The first bracket 1 is provided with a longitudinally arranged central shaft sleeve 12 , and the upper and lower ends of the central shaft sleeve 12 are fixedly connected to the first bracket 1 . The central shaft sleeve 12 is slidably sleeved on the central shaft 10 , and the central shaft sleeve 12 can perform axial sliding and circumferential rotation rel...

Abstract

The invention relates to a field back frame, which includes a second bracket, a strap and a backrest, and also includes: a central shaft, which is vertically arranged on the second bracket; The shaft sleeve is slidably fitted on the central shaft; the central spring is fitted on the central shaft, and the two ends of the central spring abut against the first support and the second support respectively. Further, it also includes: a side shaft, arranged longitudinally on the second bracket; a side spring, slidably sleeved on the side shaft; a side sliding sleeve, slidably sleeved on the side shaft, fixedly arranged on the side spring Two ends; two connecting rods, one end is connected to the side sliding sleeve in rotation, and the other end is connected to the first bracket ball. It can buffer the longitudinal shaking and yaw shaking of the load, play a role in shock absorption, and effectively reduce the pressure on the human body and shoulders caused by the shaking of the load.

Description

technical field [0001] The invention relates to the technical field of portable equipment, in particular to a field backpack. Background technique [0002] The backpack is a convenient product for people to carry, mainly used for field operations, tourism, disaster relief, military use, etc. The existing back frame is mainly composed of a back frame body and a back strap. [0003] When the human body moves, the load on the back frame will follow the human body to shake, and each time the shoulder is shaken, the load will be exerted by the load. The applied force includes the gravity of the load and the acceleration of the shaking. The greater the movement range of the load, the greater the acceleration value, and the greater the force exerted by the load on the shoulder, which greatly increases the pressure on the shoulder. Moreover, in the process of people's actions, the backpack will not only shake up and down, but also sway sideways, and the stability is poor, which wi...
