Description

Plastic shell of box body

Technical Field

The utility model relates to a plastic shell technical field of box especially relates to a plastic shell of box.

Background

At present, along with the improvement of people's life, people's trip is more and more convenient, and the plastic shell of the box of trip usefulness is more and more important, therefore to the quality of the plastic shell of box more and more high. The plastic shell of the box body is taken by people to go out, so that the plastic shell is inevitably collided and bumped, the plastic shells of most of the box bodies are made of plastic serving as raw materials, and the plastic shell of the existing box body is often directly cracked after being bumped due to the performance of the plastic itself, so that the plastic shell of the whole box body is scrapped.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a plastic shell of box, its crashproof that can be better improves the plastic shell anticollision performance of box.

The purpose of the utility model is realized by adopting the following technical scheme:

a plastic shell of a box body comprises a shell, wherein an inflatable or deflatable air bag is covered on the outer side wall of the shell; an elastic adhesive layer is arranged on the inner side wall of the shell; a plurality of elastic rod assemblies are arranged between the elastic adhesive layer and the inner side wall of the shell; a plurality of resilient rod assemblies are circumferentially spaced about the central axis of the housing.

Preferably, the elastic rod assembly comprises two elastic rods, and one ends of the two elastic rods are intersected and form a first fulcrum; the other ends of the two elastic rods are connected to the elastic glue layer; the joint points of the two elastic rods and the elastic glue layer form two second supporting points; and a connecting line of the first fulcrum and the two second fulcrums forms a triangle.

Preferably, the elastic glue layer extends around the inner side wall of the shell; the elastic adhesive layer forms four corner parts in the quadrangle of the shell; and connecting the two sides of each corner part.

Preferably, the connecting piece is arc-shaped.

Preferably, a plurality of reinforcing ribs are arranged on the inner side wall of the shell; the plurality of reinforcing ribs comprise a plurality of transverse reinforcing ribs and a plurality of longitudinal reinforcing ribs; the transverse reinforcing ribs and the longitudinal reinforcing ribs are arranged in a crossed manner.

Compared with the prior art, the beneficial effects of the utility model reside in that: the cover of its casing lateral wall is equipped with the gasbag, drags the line in-process, can aerify in the gasbag, so, can slow down the outside striking of external force to the plastic shell casing of box. When the box is stored, the air bag can be deflated, so that the storage space is reduced. In addition, the elastic glue layer that the inside wall of casing was equipped with can be further the impact that slows down external force, makes the crashproof performance of the plastic shell of this box better.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

the plastic casing of a box body as shown in fig. 1, fig. 2 and fig. 3 comprises a casing 10, wherein the outer side wall of the casing 10 is covered with an inflatable or deflatable air bag 20, and the inner side wall of the casing 10 is provided with an elastic glue layer 30. In addition, a plurality of elastic bar assemblies 40 are arranged between the elastic adhesive layer 30 and the inner side wall of the shell 10, so that the plurality of elastic bar assemblies 40 are distributed at intervals around the circumference of the central axis of the shell 10. So, when using the utility model discloses a during the plastic shell of box, when the plastic shell of box used, the accessible pump was aerifyd gasbag 20, so, can make casing 10 surface form 20 layers of gasbag that swell, so, can slow down the outside striking of external strength to the plastic shell casing 10 of box. When the plastic shell of the box body is stored, the air bag 20 can be deflated, so that the storage space is reduced. In addition, be equipped with elastic rod subassembly 40 between the plastic shell inside wall of the elastic glue layer 30 that the inside wall of casing 10 was equipped with and the box, the impact that casing 10 received can be further cushioned through elastic rod subassembly 40, and then through the further buffering of elastic glue layer 30, the impact of the plastic shell of outside box is slowed down gradually, makes the crashproof ability of the plastic shell of this box better. Of course, the elastic bar assembly 40 and the elastic glue layer 30 on the inner side wall of the casing 10 can also enhance the strength of the casing 10.

Preferably, the elastic bar assembly 40 includes two elastic bars 41, one ends of the two elastic bars 41 intersect and form a first fulcrum, and the other ends of the two elastic bars 41 are connected to the elastic glue layer 30. The joint points of the two elastic rods 41 and the elastic glue layer 30 form two second supporting points, and the connecting line of the first supporting point and the two second supporting points forms a triangle. Thus, the elastic rod assembly 40 can form a triangular support structure between the elastic adhesive layer 30 and the inner side wall of the shell 10, so that the strength is better, and the anti-collision performance is better.

Preferably, in the present embodiment, the elastic glue layer 30 extends around the inner side wall of the housing 10, and the elastic glue layer 30 forms four corner portions 31 at the four corners of the housing 10; the connecting pieces 32 between the two sides of each corner portion 31 are easy to be damaged due to the right-angle performance of the corners of the housing 10 in the actual use process, and the connecting pieces 32 arranged on the two sides of the corners in the embodiment can form triangular supports, so that the four-corner anti-collision performance of the housing 10 is improved.

Further, the connecting piece 32 is arc-shaped, and the arc-shaped connecting piece 32 can play a certain role in buffering the impact force on four corners of the housing 10.

Preferably, a plurality of reinforcing ribs may be disposed on the inner side wall of the housing 10, and the plurality of reinforcing ribs specifically include a plurality of transverse reinforcing ribs and a plurality of longitudinal reinforcing ribs; the transverse reinforcing ribs and the longitudinal reinforcing ribs are arranged in a crossed manner, so that the strength of the shell 10 can be further improved by the transverse reinforcing ribs and the longitudinal reinforcing ribs which are arranged in a crossed manner.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
