Abstract

The present invention relates to a brace backrest fixing device. Since an accurate dimension can be maintained without a welding operation, assembling properties can be improved. Also, nuts and bolts, when being disassembled, can be easily separated. When a metal composed of a lightweight material and bent in a polygonal shape is combined with a net wrapped over the metal, a cable tie is used. A brace is hung on an upper end ring of a frame, and a waist band is assembled with the lower end of a backrest by a bolt and a nut. After an engine is combined to a frame, and a cable tie is used corresponding to multiple holes. Then, assembling properties can be improved. During disassembly, separation can be easily performed. The entire quality of a brace backrest can be improved. In addition, a decoration which stimulates acupuncture point is attached to the backrest to be helpful for health.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

[0001] The present invention relates to an initial resting device for a backrest of a mobile phone, and more particularly, to a backrest for a backrest of a mobile phone, will be.

In the initial Melbang backrest, there is no decoration that tightens both breasts in any product. When working, the engine's body moves back and forth whenever the engine is moved to the shoulder, even when viewed from afar. When it is more difficult, If you get caught in your foot, you will get a safety problem. In the early days, when you turn around while you are turning, you have to worry about the safety of the engine when you lose weight. Also, since the backboard was small, I had a lot of back pain and rats when I was working for a long time. In addition, it is difficult to ventilate on the back, and after sweating, the worker is exhausted after finishing work, so I have to go to the mowing site to find a specialist, and then personally experience it.

A conventional fixing device 1 for a backrest of a Melbang backrest will now be described with reference to FIG.

First, the material is cut into the lightest metal, bent through a plurality of holes in accordance with the center, and then joined with the metal (2), and then the metal is shaped like a frame. . The Melbang is a fixing device for the Melbun backrest of the finished product of section (5)

In the above-mentioned prior art, the research of the backrest of the Melbang was carried out in the center of the core metal product which has achieved the idea of putting the engine of the early stage into the mold, to be.

In the above-mentioned prior art, the inventor developed the reality that the initial malbang would be disappeared and the work was done with fresh and happy mind when the work was done.

It is made by cutting the metal of the lightest material to the spine, bending and bending a number of holes according to the center, and then making a frame by binding. Then, a cover for protecting the back bone is attached under the metal mesh, Is a feature of the fixing device of the completed Melbun backrest.

In order to solve the above-mentioned problems, the present invention has been developed to solve the above-mentioned problems, and therefore, the backrest of the Malthusian is fast in disassembly and fastening and is easily separated from the work of bolts: nuts: navel: cable ties, And a cable tie is formed in accordance with the shape of the work.

The present invention can improve the assemblability by fixing the bolt: nuts: nibet: cable tie, and it is possible to maintain the accurate product as well as to provide ease of operation without welding, and the bolt nut can be easily disadvantageous in disassembly, The backrest can be easily made, thereby improving the disassembly and assembling property, and improving the quality of the entire back of the Melan Backrest.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of the disassembled state of the backrest fixing device of the present invention,

Fig. 2 is a perspective view showing a main part of a backrest fixing device (bolt: nuts: nibbed: perspective view of a cable tie)

FIG. 3 is a cross-sectional view of a metal backrest fixing device in which a mesh of a metal to which the technique of the present invention is applied,

Fig. 4 is a schematic view of an embodiment of the present invention. Fig. 4 is a cross-

Fig. 5 is a cross-sectional view illustrating the state of use combined with the engine of the backrest fixing device of the present invention.

The state of use of the backrest fixing device of the present invention is as follows.

First, the metal of a light material is bent without being welded 101, and then the metal of the bundled metal of the chain 102 is interlocked with the frame of the backrests 103 and 104 and the bolt: Respectively.

The use state of the backrest fixing device 106 to which the present invention is applied will be described as follows. Attach the hip bone cover to the metal matt bottom (107) (102) Do not move firmly when tied with a cable tie.

In the state where the bolts are fixed as described above, the joints (108) and (109) of the joints (110) are combined (110)

The present invention has the advantage that it can easily perform the fixing and replacement work because the exact specification of the bolt and the nut is applied to the work and the finished product (111) can be performed quickly when it is disassembled.
