Description

Packing case protective sleeve

Technical Field

The utility model relates to the technical field of packaging boxes, in particular to a packaging box protective sleeve.

Background

The publication number CN210422174U discloses an anti-collision structure of intelligent lock, and it specifically discloses a protective sheath, including horizontal stretching assembly, vertical stretching assembly and protection angle cover, wherein horizontal stretching assembly and vertical stretching assembly still include pull rod, stretch soon, spacing slider, spacing spout and elastic spring. The whole structure of the stretching structure is very complex, for example, compression springs are required to be arranged at two ends of a pull rod, and two ends of the pull rod are connected with stretching blocks; in addition, when protecting articles, as the two compression springs are connected through a corresponding pull rod, namely the extension and contraction between the two adjacent protection angle sleeves are limited by the length of the pull rod, the extension and contraction distance between the two protection angle sleeves is shorter, so that the problem of insufficient size can easily exist when protecting larger articles.

Disclosure of Invention

Aiming at the problems existing in the prior art, the utility model aims to provide a packing box protective sleeve which has the characteristics of simple structure, simple production process and lower production cost through the design of integrally forming an angle sleeve and an elastic connecting piece; and the wave-shaped design of the elastic connection piece enables the elastic connection piece to have a larger stretching distance after being fully stretched.

In order to achieve the above object, the technical scheme of the present utility model is as follows: a packing case protective sleeve comprises four corner sleeves, wherein the four corner sleeves are fixedly connected through elastic connecting pieces and form a closed structure.

For the additional structure of the above technical scheme, the method further comprises the following scheme:

further, the angle sleeve comprises a first side plate, a second side plate and a bottom plate, wherein the first side plate is fixedly connected with one side of the bottom plate, the included angle is an obtuse angle, the second side plate is fixedly connected with the other side of the bottom plate, the included angle is an obtuse angle, and the first side plate is fixedly connected with the second side plate and forms an inward L-shaped included angle.

Further, the corner of the L-shaped included angle is arc-shaped.

Further, the elastic connecting pieces are provided with four pieces, and two ends of each elastic connecting piece are respectively connected with one side of each two adjacent bottom plates.

Further, the elastic connecting piece is in a strip wave shape.

Further, the angle sleeve and the elastic connecting piece are integrally formed.

Further, each corner sleeve can be used for being sleeved at four corners of the box body.

The beneficial effects of the utility model are as follows:

the elastic connecting piece is of a wavy shape, the angle sleeve and the elastic connecting piece are integrally formed, only one elastic connecting piece is arranged without other parts, so that the structure is simple, the cost is low, the elastic connecting piece can be assembled without the procedures of assembly and the like, the production cost can be reduced to a certain extent, and the protective sleeve with low cost and easy production can meet the demands of cheap packaging materials in the market; meanwhile, the wave-shaped design of the elastic connecting piece is utilized, so that the elastic connecting piece can have a larger stretching distance after being fully stretched, and a packaging box with a larger size can be protected.

For a better understanding and implementation, the present utility model is described in detail below with reference to the drawings.

Detailed Description

Specific embodiments in accordance with the present disclosure are described in detail below with reference to the various drawings.

As shown in fig. 1, a packaging case protective sleeve comprises four corner sleeves 1, and the four corner sleeves 1 are fixedly connected through elastic connecting pieces 5 to form a closed structure.

The angle sleeve 1 comprises a first side plate 2, a second side plate 3 and a bottom plate 4, wherein the first side plate 2 is fixedly connected with the bottom plate 4, the included angle is an obtuse angle, the second side plate 3 is fixedly connected with the bottom plate 4, the included angle is an obtuse angle, the corner of the first side plate 2 is fixedly connected with the second side plate 3, an inward L-shaped included angle is formed, and when the box body is assembled to the angle sleeve 1 from top to bottom, the box angle is easier to place into the angle sleeve 1 due to the design of the obtuse angle. The L-shaped included angle is matched with the box angle, so that the box angle can be protected more fully and stably. The L-shaped included angle is arc-shaped, and in the movement of the box body, the effect of external force can be buffered, so that the box angle is not easy to squeeze and deform, and the protection performance is better.

Two ends of each elastic connecting piece 5 are respectively connected with one side of the bottom plate 4, so that a protective sleeve capable of wrapping four corners of the box body is formed, each corner sleeve 1 can be used for being sleeved at the four corners of the box body, and the purpose of wrapping the corners of the box body is achieved.

The elastic connecting piece 5 is in a strip shape and is in a wave shape, when the elastic connecting piece 5 is stretched, the elastic connecting piece 5 is used for being provided with the characteristic of being capable of extending and rebounding, and when a large packing box is encountered, the elastic connecting piece 5 is stretched to enlarge the space which can be wrapped by the packing box protective sleeve, so that the packing box protective sleeve can be matched with the size of the packing box.

As shown in fig. 2-4, when the packaging is used, the corner sleeves 1 are stretched outwards firstly, the corner sleeves 1 are affected by the elasticity of the elastic connecting pieces 5, so that the wrapping area of the whole packaging protective sleeve is increased, then four corners of the box body 6 are placed on the corresponding corner sleeves 1, the elastic connecting pieces 5 rebound elastically, so that one corner of the box body 6 is sleeved on each corner sleeve 1, and finally, the wrapping of the four corners of the box body 6 is completed.

The scope of the present disclosure is defined not by the above-described embodiments but by the appended claims and their equivalents.
