Abstract

The utility model discloses a kind of draw-bar box, including casing and case lid, the casing is provided with pull bar and roller, and the case lid is hinged on the side of casing；The casing is a frame structure, it is characterised in that：The side wall of the casing is provided with some grooves or raised line.The draw-bar box can reduce Board material for box thickness and intensity more preferably, casing cost and weight can be reduced, the probability scratched by body side can be reduced.

Description

Draw-bar box

Technical field

This utility model is related to case and bag technical field, is especially a kind of draw-bar box.

Background technology

Draw-bar box refers to the luggage case with pull bar and roller.Easy to use because of which, carrying medicated clothing etc. becomes travelling, go out and Widely used.Current draw-bar box includes that casing and case lid, the casing are provided with pull bar and roller, and the case lid is hinged Side in casing；The casing is a frame structure.The draw-bar box of this structure is suffered from the drawback that above：Due to casing Side wall is generally smooth flat board, so in order to be able to reach enough intensity, needs thicker sheet material, which increases casing Cost, while also increase the weight of casing；Again as the side of the casing is bright finish, when using, easily scratched, from And affect the presentation quality of whole casing.

Utility model content

The technical problems to be solved in the utility model be to provide one kind can reduce Board material for box thickness and intensity more preferably, energy Reduce casing cost and weight, the draw-bar box of the probability scratched by body side can be reduced.

The technical solution of the utility model is to provide a kind of draw-bar box with following structure, including casing and case lid, institute State casing and be provided with pull bar and roller, the case lid is hinged on the side of casing；The casing be a frame structure, the casing Side wall be provided with some grooves or raised line.

The some raised lines are located at the side-wall outer side of casing, the medial part of the side wall of the corresponding casing of each raised line Position is then a groove.

The raised line is that parallel distribution between some raised lines is corresponding along the ring rib that encloses of framework one of casing Groove is also the annular groove that encloses of framework one along casing, the parallel distribution of some grooves.

The cross section of the raised line is rectangular.

The casing is a monoblock sheet material, and the casing is provided with a soldered.

After using above structure, this utility model has advantages below：Due to the side wall of the casing be provided with some recessed Groove or raised line, raised line can increase the intensity of casing, under the sufficient intensity for ensureing casing, so as to reduce the thickness of Board material for box Degree, while can also reduce weight and the cost of casing；Again as the side of the casing increases after raised line, no longer it is bright finish, this Sample can reduce the contact surface with touched object, so as to reduce the probability scratched by body side when using.

Used as improvement, some raised lines are located at the side-wall outer side of casing, the side of the corresponding casing of each raised line The inside line of wall is then a groove, and so in processing, energy one-shot forming out, makes easy to process.

As improvement, the raised line be along casing framework one enclose ring rib, parallel distribution between some raised lines, Corresponding groove is also that the parallel distribution of some annular grooves can be more balanced along the annular groove that encloses of framework one of casing Bear external force.

Used as improvement, the cross section of the raised line is rectangular, and convenient processing can bear bigger external force simultaneously.

Used as improvement, the casing is a monoblock sheet material, and the casing is provided with a soldered, greatly increases the whole of casing Body intensity.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, draw-bar box of the present utility model, including casing 1 and case lid 2, the casing 1 Pull bar 3 and roller 4 is provided with, the case lid 2 is hinged on the side of casing 1；The casing 1 be a frame structure, the casing 1 Side wall be provided with some grooves 1.2 or raised line 1.1, be provided with spacing between adjacent two raised lines 1.1, in the same manner two grooves Spacing also is provided between 1.2.That is the medial wall of casing 1 or lateral wall both sides can be provided with some grooves 1.2 Or raised line 1.1, or the medial wall of casing 1 is provided with some grooves 1.2 or raised line 1.1, if or the lateral wall of casing 1 be provided with Dry bar groove 1.2 or raised line 1.1, certain raised line 1.1 or groove 1.2 individually can be provided with, it is also possible to be simultaneously provided with.

The present embodiment, some raised lines 1.1 are located at the side-wall outer side of casing 1, the corresponding case of each raised line 1.1 It is a corresponding groove 1.2 that the inside line of the side wall of body 1 is then a groove 1.2, the i.e. back side of each raised line 1.1.

The raised line 1.1 be along casing 1 framework one enclose ring rib, parallel distribution between some raised lines 1.1, phase Corresponding groove 1.2 be also along casing framework one enclose annular groove, some 1.2 parallel distributions of groove.

The cross section of the raised line 1.1 is rectangular, and the cross section can also be that a trapezoidal, circular part or positive six become The other shapes such as a part for shape.

The casing 1 is a monoblock sheet material, and the casing 1 is provided with a soldered, will shape after a monoblock sheet metal bending Into a framework, then in the head and the tail stitching portion of sheet material using being welded and fixed.

Embodiment one：If Fig. 5 is the one of which cross section of raised line 1.1, its cross section is rectangle.

Embodiment two：If Fig. 6 is the one of which cross section of raised line 1.1, its cross section is semicircle.
