Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a damp-proof packaging bag comprises a bag body 1, wherein a sealing component 2 is arranged on the outer side of the bag body 1, and the sealing component 2 comprises a first positioning plate 201, an L-shaped plate 202, a positioning plate 203, a second positioning plate 204, an elastic rope 205, a positioning column 206, a convex strip 207 and a concave strip 208;

1 one side of the bag body bonds and has first locating plate 201, sliding connection has L shaped plate 202 to the side of first locating plate 201, L shaped plate 202 one end fixedly connected with

limiting plate

203, 1 opposite side of the bag body bonds and has second locating plate 204, stretch cord 205 is all installed to position department about the L shaped plate 202 other end, stretch cord 205 one end fixed mounting has reference column 206, reference column 206 fixed mounting is in first locating plate 201 side, 1 inner wall symmetry both sides of the bag body are equipped with sand grip 207 and gib 208 respectively, sand grip 207 blocks and locates the gib 208 inboardly.

Further, a U-shaped inner cavity is formed between the limiting plate 203 and the L-shaped plate 202, and the first positioning plate 201 and the second positioning plate 204 are respectively located at two sides of the U-shaped inner cavity, so that the limiting plate 203 and the L-shaped plate 202 can clamp and fix the first positioning plate 201 and the second positioning plate 204.

Further, guiding hole 3 has been seted up to L shaped plate 202 side, guide post 4 is all installed at first locating plate 201 side both ends, guide post 4 slides and inserts and locate 3 inboards of guiding hole, the spacing cap 5 of 4 one end fixedly connected with of guide post can play the limiting action to the direction of activity of L shaped plate 202, can restrict the big home range of L shaped plate 202 simultaneously.

Furthermore, the lifting lugs 6 are mounted on two sides of the top end of the bag body 1, the lifting holes 7 are formed in the side faces of the lifting lugs 6, the reinforcing belt 8 is bonded on the side faces of the bag body 1, and the reinforcing belt 8 bypasses from the bottom end of the bag body 1 and is connected with the lifting lugs 6 on two sides into a whole, so that the strength of the lifting lugs 6 can be enhanced, and the bag body is not prone to fracture.

Further, the bag body 1 is composed of an outer bag layer 101, a bag clamping layer 102 and an inner bag layer 103, the bag clamping layer 102 is adhered to the inner side of the outer bag layer 101, and the inner bag layer 103 is adhered to the inner side of the bag clamping layer 102, so that the bag body 1 is of a multilayer structure, and the structural strength of the bag body 1 is higher.

Further, the bag clamping layer 102 is a fiber waterproof film, so that the bag body 1 has good waterproof and moisture-proof properties.

The working principle is as follows: when the opening of the bag body 1 needs to be opened, the L-shaped plates 202 on the two sides are respectively pulled outwards, so that the end parts of the first positioning plate 201 and the second positioning plate 204 are separated from the space between the L-shaped plates 202 and the inner sides of the limiting plates 203, the limiting plates 203 do not limit the second positioning plate 204, at the moment, the elastic ropes 205 at the end parts of the L-shaped plates 202 are in a stretching state, then the opening of the bag body 1 is separated, the convex strips 207 on the inner side of the bag body 1 are separated from the inner sides of the concave strips 208, so that the opening of the bag body 1 can be opened, the operation is convenient, when the opening of the bag body 1 needs to be sealed, the L-shaped plates 202 are respectively pulled outwards to ensure that the convex strips 207 on the inner side of the bag body 1 are clamped into the inner sides of the concave strips 208 again, then the position of the L-shaped plates 202 is slowly reset until the end parts of the first positioning plate 201 and the second positioning plate 204 abut against the end parts of the L-shaped plates 202, the outward side of the second positioning plate 204 and the first positioning plate 201 are respectively clung to the outward side of the limiting plates 203 and the L-shaped plates 202, thereby make second locating plate 204 and first locating plate 201 unable outside separately, thereby can the 1 opening of the bag body tightly close, through set up the strengthening band 8 at the 1 skin of the bag body, and the strengthening band 8 is walked around and is bonded with the bag body 1 from the 1 bottom of the bag body, simultaneously the strengthening band 8 is even as an organic whole with carrying the ear 6, thereby can make the strengthening band 8 can bear partly bag body 1 weight, thereby can prevent to carry the ear 6 phenomenon of breaking off, through setting up the bag body 1 into three layer construction, the intermediate level is the double-layered bag layer 102 of fibre water proof membrane, thereby make the bag body 1 have fine waterproof, moisture-proof ability.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
