Technical Field

[0001] The utility model specifically relates to a quick-release buffer backrest frame. Background Art

[0002] At present, with the rapid development and changes of society, new requirements have been put forward for auxiliary robots and carrying devices in many fields such as emergency rescue, medical rehabilitation, and load transportation. How to reduce the fatigue state of users under long-distance carrying, how to effectively decompose the human body's load-bearing pressure, and how to improve the usability are the research topics of ergonomics. However, the main research direction of the backrest frames on the market is mainly how much weight they can bear, and often the backrest frames are connected to the waistband. During long-distance bumps, excessive weight is also likely to impact the human waist, resulting in damage to the human waist. Content of the Utility Model

[0003] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a quick-release buffer backrest frame.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a quick-release buffer backrest frame, including a backrest frame main body and a waist seal member. A buffer block is installed at the lower end of the backrest frame main body, and the buffer block is detachably installed on the waist seal member.

[0005] Preferably, the waist seal member includes a mounting seat, and a hook plate for clamping the buffer block is rotatably arranged on the mounting seat.

[0006] Preferably, the buffer block includes a mounting portion, a buffer portion, and a limiting portion. The mounting portion is installed on the backrest frame main body, the limiting portion is detachably installed on the waist seal member, the buffer portion is located between the mounting portion and the limiting portion, and the buffer portion is arranged in a curved arc shape.

[0007] Preferably, a bent groove is formed at the top of the hook plate, the cross-section of the limiting portion is semi-elliptical, and the top of the limiting portion is detachably embedded in the bent groove.

[0008] Preferably, a rotating shaft is penetrated through the middle of the hook plate, both ends of the rotating shaft are rotatably installed on the mounting seat, and a pressing portion is arranged at the bottom of the hook plate. A torsion spring is arranged on the rotating shaft.

[0009] Preferably, the cross-section of the backrest frame main body is arranged in a shape similar to the letter 'S'.

[0010] Compared with the prior art, the utility model has the following beneficial effects: The quick-release buffer backrest frame detachably connects the backrest frame main body and the waist seal member, and a buffer block is arranged between the backrest frame main body and the waist seal member. While achieving quick separation, it can also buffer the impact force on the waist through the buffer block, reducing waist injuries. Description of the Drawings

[0016] In order to make the above features and advantages of the present utility model more obvious and understandable, specific embodiments are hereby given and detailed descriptions are made below in conjunction with the accompanying drawings.

[0017] As Figures 1 - 4 shown, a quick-release buffer backrest includes a backrest main body 1 and a waist belt 2. A buffer block 3 is installed at the lower end of the backrest main body 1, and the buffer block 3 is detachably installed on the waist belt 2. During actual use, the waist belt 2 is used to be arranged on the waist belt.

[0018] A plurality of hollow grooves are formed on the backrest main body 1. The weight can be effectively reduced, and ventilation can be achieved during actual use. At the same time, it can provide an auxiliary function for the combination and installation of the backrest and the backpack. For example, the webbing on the backpack can pass through the hollow grooves for fixation.

[0019] In this embodiment, the waist belt 2 includes a mounting seat 11, and a hook plate 12 for clamping the buffer block 3 is rotatably arranged on the mounting seat 11.

[0020] A limiting cavity 10 is arranged on the mounting seat 11 at the front side of the hook plate 12, and the buffer block 3 is detachably installed in the limiting cavity 10. An arc-shaped groove is formed at the bottom of the limiting cavity 10, and the depth of the arc-shaped groove is relatively shallow, which can play a role in simply limiting the buffer block 3. When the hook plate 12 and the buffer block 3 are separated, the buffer block 3 can be separated from the limiting cavity 10 with appropriate force.

[0021] In this embodiment, the buffer block 3 includes a mounting portion 4, a buffer portion 5, and a limiting portion 6. The mounting portion 4 is mounted on the backrest main body 1. The limiting portion 6 is detachably mounted on the lumbar support member 2. The buffer portion 5 is located between the mounting portion 4 and the limiting portion 6, and the buffer portion 5 is arranged in a curved arc shape.

[0022] A plurality of first threaded holes are formed in the mounting portion 4, and second threaded holes corresponding to the plurality of first threaded holes are formed in the backrest main body 1. The mounting portion 4 and the backrest main body 1 are fixedly connected by bolts.

[0023] In this embodiment, a bent groove 7 is formed at the top of the hook plate 12. The cross-section of the limiting portion 6 is semi-elliptical, and the top of the limiting portion 6 is detachably embedded in the bent groove 7.

[0024] In this embodiment, a rotating shaft 8 passes through the middle of the hook plate 12. Both ends of the rotating shaft 8 are rotatably mounted on the mounting seat 11. A pressing portion 9 is provided at the bottom of the hook plate 12, and a torsion spring is provided on the rotating shaft 8.

[0025] During use, by pressing the pressing portion 9 of the hook plate 12, the top of the hook plate is separated from the limiting portion 6 of the buffer block 3.

[0026] In this embodiment, the cross-section of the backrest main body 1 is arranged in a shape similar to an S.

[0027] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any person skilled in the art who does not depart from the content of the technical solution of the present invention and makes any simple modifications, equivalent changes, and modifications to the above embodiments based on the technical essence of the present invention shall fall within the scope covered by the present invention.
