Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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 all belong to the protection scope of the present invention.

Example 1:

as shown in fig. 1 to 4, the corrugated cardboard liner for pressure protection described in this embodiment includes a liner body 1, the liner body 1 is made of corrugated cardboard, the liner body 1 includes at least one filler block 5, articles are placed on the filler block 5 for use, and the filler blocks 5 may be set to be one, two, four, etc., and are selected for use according to the actual size and requirements of the articles;

the lining blocks 5 comprise side plates 501 and a bottom plate 502, at least one side of each side plate 501 is provided with a buffer part 3, each buffer part 3 comprises a fixing part 301, a bending part 302 and a clamping part 303, the fixing part 301 is provided with a fixing part 4, the fixing part 301 is detachably fixed on the side plate 501 by the fixing part 4, the bottom of each side plate 501 is provided with a buffer groove 6 corresponding to the buffer part 3, the bending part 302 and the clamping part 303 are inserted by the buffer grooves 6, the clamping part 303 limits the bottom end of the bending part 302 at the inner side of the side plate 501, the outer vertex angle of the bending part 302 is abutted against the inner wall of a box body where the lining body 1 is positioned, when the vertex angle of the bending part 302 is stressed, the elastic deformation of the bending part 302 moves towards the inner part of the buffer groove 6, the top of the bottom plate 502 is provided with an elastic support member, when the lining blocks 5 are used, for example, the four lining blocks 5 can be placed at the four corners at the inner side bottom of an outer packaging box, the cushion member 3 on the side plate 501 of the lining block 5 acts, the vertex angle of the bending part 302 of the cushion member 3 is abutted against the corresponding inner wall of the packing box, an article is slowly put into the packing box from the top of the packing box, the four corners and the edge of the bottom of the article are contacted with the side plate 501 of the lining block 5, the side plate 501 is close to the inner wall of the packing box, at the moment, the bending part 302 is compressed by the inner wall of the packing box, so that the bottom of the bending part 302 enters the inside of the buffer groove 6 for buffering, when in actual use, the width of the buffer groove 6 is slightly larger than the width of the paperboard of the bending part 302, the bending part 302 starts to be bent from the fixing part 301, the bottom of the bending part 302 penetrates through the buffer groove 6 and is inclined to be connected with the bottom plate 502 at a certain angle, at the moment, when the bending part 302 moves towards the inside of the buffer groove 6, larger friction is generated for buffering; obviously, there is a gap between the above-mentioned bent portion 302 and the inner wall of the box where the liner is located, so when an article is placed in the box, its size can be within a certain range, that is, the article within a certain size range can be installed and buffered, the size range of the article depends on the initial distance between the bent portion 302 and the inner wall of the box in the buffer member 3, because the liner is not fixedly connected with the inner wall of the box, when the installation size is smaller than the article inside the box, the bent portion 302 at both sides moves towards the inside of the buffer slot 6, when the article is larger, the moving distance increases, the distance between the bent portion 302 and the inner wall of the box decreases, when the article is smaller, the moving distance between the bent portion 302 and the inner wall of the box is smaller, when transporting or transporting, the article can slightly move and rock in the box, but all are within the protection range of the liner.

The angle formed between the locking portion 303 and the bottom of the bent portion 302 is an acute angle, so that when the locking portion 303 is inserted into the buffer slot 6, the locking portion 303 can be easily guided into the buffer slot 6 due to the acute angle, and the locking portion 303 is not easily removed from the buffer slot 6.

Fixing member 4 includes fixture block 401, grafting portion 402 and location portion 403 constitute and form the assembly of arrow point form, fixed part 301 and curb plate 501's corresponding position is opened there is fixed orifices 9, fixing member 4 inserts fixed orifices 9, there is the pointed end of arrow to insert resistance little, and then block by the arrow tail end when fixing member 4 will reverse extraction, thereby with fixed part 301 spacing be fixed in on curb plate 501, the fixed limit is not died here, when the transportation collides, here can become flexible slightly in order to guarantee better cushioning effect.

Elastic support includes supporting pad 7 and backing plate 8, and the glue is passed through at supporting pad 7 both ends and bonds in bottom plate 502 and backing plate 8, and supporting pad 7 is the folding cushion that forms of corrugated container board.

The number of the filler blocks 5 is four, and the four filler blocks 5 are respectively arranged at four corners in the box body where the liners are arranged.

The filler blocks 5 are eight, the eight filler blocks 5 are divided into two groups which are symmetrical up and down, the two groups of filler blocks 5 which are symmetrical up and down are respectively arranged at eight vertex angles at the upper side and the lower side of the surface of the article, and the top and the side of the article can play an all-round protection role.

It should be noted that, the parts inside the lining block 5 may only use corrugated paper as a raw material, and materials such as PE material or rubber may also be applied to the production of the parts of the lining block 5.

This embodiment is when implementing, when filler block 5 uses, filler block 5 sets up four, four filler blocks 5 are placed in the four corners department of the inboard bottom of outside packing box, 3 effects of bolster on the curb plate 501 of filler block 5, the apex angle of the kink 302 of bolster 3 offsets with the inner wall that the packing box corresponds, article are slowly put into by the packing box top, the bottom four corners department and the edge of article contact the curb plate 501 of filler block 5, curb plate 501 is close to the inner wall of packing box, kink 302 can be compressed by the packing box inner wall this moment, thereby kink 302 bottom entering dashpot 6 is inside to be cushioned, during the practical use, the width of dashpot 6 can slightly be greater than the cardboard width of kink 302, and kink 302 begins to buckle by fixed part 301 department, the bottom of kink 302 passes dashpot 6 and the slope has certain angle to meet with bottom plate 502, there is great friction when kink 302 moves towards dashpot 6 inside at this moment for buffering.

The present invention is not limited to the above preferred embodiments, and any person can obtain other products in various forms without changing the shape or structure of the product, and all the products having the same or similar technical solutions as the present invention fall within the protection scope of the present invention.
