Title:
DETACHABLE MULTIFUNCTIONAL BACK PAIR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/240807
Kind Code:
A1
Abstract:
A detachable multifunctional back pair structure, comprising: a frame (1) mounted on the back surface of a backpack; and a support member (2) arranged on the side of the frame (1) away from the backpack. The upper and lower ends of the support member (2) are detachably connected to the frame (1) respectively. The support member (2) comprises at least three support blocks (21) hinged in sequence, the support blocks (21) being tightly attached to the back of a human body. The parts can be quickly detached and replaced, are easy to use, and are mounted on the back surface of the backpack by means of the frame (1), thereby keeping the back surface of the backpack straight, thereby facilitating the mounting of the support member (2). When the back pair structure is used in conjunction with back straps, the pressure of the backpack can be evenly distributed to the shoulder of the user to the back or even the waist of the user, thereby alleviating the burden of the shoulder.
