Abstract

The utility model provides a portable mechanical backrest, which comprises a frame, wherein limit sleeves are arranged on two sides of the front end of the frame, elastic reciprocating mechanisms are arranged in the limit sleeves, and a backrest plate is arranged between the elastic reciprocating mechanisms on two sides; the backrest is independently arranged, the use is very convenient, the backrest can be directly fixed on the existing backrest for use, the application range is wide, and the backrest plate can be adjusted in height by arranging the elastic reciprocating mechanism, so that the backrest is suitable for different back curve requirements, and the backrest can be automatically reset under the condition of inapplicability.

Description

Portable mechanical backrest

Technical Field

The utility model relates to the field of backrests, in particular to a portable mechanical backrest.

Background

Most of the existing backrests are in a fixed form, and the back of a human body has a certain curve, so that the comfort of the backrest is poor when the backrest is used, and although some seats capable of adjusting the shape according to the curve of the back of the human body appear in the prior art, the seats can only be used under specific conditions, and the application range is small.

Therefore, there is a need for a portable mechanical back that can be used alone with a fixed shape of the existing seat back.

Disclosure of Invention

The utility model aims to provide a portable mechanical backrest, which solves the problems that the existing backrest is fixed in shape and cannot be used independently.

In order to achieve the above object, the present utility model provides the following solutions:

the utility model provides a portable mechanical backrest which comprises a frame, wherein limiting sleeves are arranged on two sides of the front end of the frame, elastic reciprocating mechanisms are arranged in the limiting sleeves, and a backrest plate is arranged between the elastic reciprocating mechanisms on two sides.

Preferably, the back of the frame is provided with stiffening ribs.

Preferably, the elastic reciprocating mechanism comprises a guide post, the guide post is telescopically limited in the limit sleeve, and a spring is sleeved on the outer side of the guide post.

Preferably, a gap is arranged between the back boards.

Preferably, the outer surface of the backboard is provided with a flexible decorative layer.

Compared with the prior art, the utility model has the following beneficial technical effects:

the utility model provides a portable mechanical backrest, which comprises a frame, wherein two sides of the front end of the frame are provided with limiting sleeves, an elastic reciprocating mechanism is arranged in each limiting sleeve, and a backrest plate is arranged between the elastic reciprocating mechanisms on two sides; the backrest is independently arranged, the use is very convenient, the backrest can be directly fixed on the existing backrest for use, the application range is wide, and the backrest plate can be adjusted in height by arranging the elastic reciprocating mechanism, so that the backrest is suitable for different back curve requirements, and the backrest can be automatically reset under the condition of inapplicability.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model aims to provide a portable mechanical backrest which solves the problems existing in the prior art.

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

Example 1:

the embodiment provides a portable mechanical backrest, which comprises a frame 1, wherein the back of the frame 1 is provided with a reinforcing rib, so that the strength of the frame 1 is improved, two sides of the front end of the frame 1 are provided with limiting sleeves 2, elastic reciprocating mechanisms 3 are arranged in the limiting sleeves 2, a backrest plate 4 is arranged between the elastic reciprocating mechanisms 3 on two sides, a gap is arranged between the backrest plate 4, smooth movement of the backrest plate is ensured, and a flexible decorative layer is arranged on the outer surface of the backrest plate 4 to play roles of decoration and protection.

Specifically, the elastic reciprocating mechanism 3 includes a guide post 31, the guide post 31 is telescopically limited in the limiting sleeve 2, and a spring 32 is sleeved outside the guide post 31.

The utility model provides a portable mechanical backrest, which has the following working principle: the frame 1 is fixed on a conventional seat back through a binding belt, when a user leans backwards, the backrest plate 4 is pressed, the springs 32 deform, the guide posts 31 slide in the limit sleeves 2, the backrest plate 4 can form a corresponding curve according to the back curve of a human body, and after the pressure is relieved, the backrest plate 4 can automatically reset under the action of the springs 32.

The principles and embodiments of the present utility model have been described with reference to specific examples, which are provided to facilitate understanding of the method and core ideas of the present utility model; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings. In summary, the present description should not be construed as limiting the utility model.
