The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figure 1, shown in Figure 5, the draw-bar box that the utility model provides, comprises casing and the case lid can folding being connected with casing, also comprises the pull bar (not showing on figure) being flexibly connected with casing, because pull bar is prior art, so be not described in detail.Casing and case lid are plastic material, as PP, ABS etc. makes.Case lid comprises that the first housing 11, the first housing 11 inner side surroundings are fixedly connected with continuously or intermittently and is useful on the first reinforcement 14 that prevents case lid distortion; Casing comprises that the second housing 21, the second housing 21 inner side surroundings are fixedly connected with to be useful on continuously or intermittently and prevents that the second reinforcement 24, the first reinforcements 14 and second reinforcement 24 of box deformation from being plastic cement material.

Further, as shown in Figure 4, case lid also comprises the first buffering suface 13 extending to form along the outside bending of the first housing 11 outer rim, and the first side wall 12 that deviates from the direction setting of the first housing 11 on the other end edge of the first buffering suface 13, preferably, the first side wall 12 is parallel with the first housing 11, the first buffering suface 13 is perpendicular to the first housing 11 and the first side wall 12, when case lid is subject to external pressure, the first buffering suface 13 available buffer pressure, prevent its distortion.The first housing 11, First terrace 13 is one-body molded by mold injection with the first side wall 12 threes, and the fixed form between three also and be confined to this certainly.As shown in Figure 2, be fixedly connected with continuously or intermittently and be useful on the first reinforcement 14 that further prevents case lid distortion on First terrace 13, strengthen the intensity of First terrace 13, preferably, the width of the first reinforcement 14 is identical with the width of First terrace 13.In order to reduce the production process of draw-bar box, the first reinforcement 14 is one-body molded by mold injection with First terrace 13, and is positioned at First terrace 13 inwalls, therefore can not affect the attractive in appearance of case lid; The fixed form of certain the first reinforcement 14 is also not limited to this, also can be gluing or hot melt on First terrace 13.It is tabular that the cross section of the first reinforcement 14 can be, and can be also wavy (as shown in Figure 2), zigzag (as shown in Figure 7), strip (as shown in Figure 8,9), netted, wavy and the combination of strip or the combination (as shown in figure 10) of zigzag and strip etc.; Also can be sawtooth like shape, as shown in figure 10, the break of the first reinforcement 14 1 sides that are comprised of many broken lines is to extending near First terrace 13 edges the shape that a reinforcement projection presents; The structure of the first reinforcement 14 is supporting box cover better not only, prevents case lid distortion, and can save cost.The first reinforcement 14 at least, around First terrace 13 1 weeks, specifically can be adjusted according to the size of draw-bar box.

As shown in Figure 5, Figure 6, casing also comprises the second buffering suface 23 extending to form along the outside bending of the second housing 21 outer rim, and the second sidewall 22 that deviates from the direction setting of the second housing 21 on the other end edge of the second buffering suface 23, preferably, the second sidewall 22 is parallel to the second housing 21, the second buffering sufaces 23 perpendicular to the second housing 22 and the second sidewall 22, when casing is subject to external pressure, the second buffering suface 23 available buffer pressure, prevent box deformation.One-body molded by mold injection between the second housing 21, second step face 23 and the second sidewall 22 threes, the fixed form between three is also not limited to this certainly.On second step face 23, be fixedly connected with continuously or intermittently and be useful on the second reinforcement 24 that further prevents box deformation, preferably, the width of the second reinforcement 24 is identical with the width of second step face 23, can prevent better box deformation.In order to reduce the production process of draw-bar box, the second reinforcement 24 is integrated by mold injection with second step face 23, and the second reinforcement 24 is positioned at second step face 23 inwalls, therefore can not affect the attractive in appearance of casing; The fixed form of certain the second reinforcement 24 is also not limited to this, also can be gluing or hot melt on second step face 23.The cross section of the second reinforcement 24 is identical or similar with the cross sectional shape of the first reinforcement 14, can be tabular, also can be wavy, zigzag, strip, netted, wavy and the combination of strip or the combination of zigzag and strip etc., also can be sawtooth like shape, at the break place of the second reinforcement 24 1 sides that formed by many broken lines, to close second step face 23 edges, extend the shape that a reinforcement projection presents; The structure of the second reinforcement 24 is supporting box better not only, prevents box deformation, and can save cost.The second reinforcement 24 at least, around second step face 23 1 weeks, can be adjusted according to the size of draw-bar box.

Draw-bar box in use, the opening part of casing and case lid the most easily produces distortion and is difficult for restoring, therefore the draw-bar box that the utility model provides is set up reinforcement respectively near the First terrace 13 casing and case lid opening part and second step face 23, prevent its distortion, and the first reinforcement 14 and the second reinforcement 24 all form by mold injection, production technology is easier, also can not affect the overall aesthetics of draw-bar box simultaneously, and its material is identical with draw-bar box, lighter, with respect to steel ring of the prior art and outside support member, also can not increase the weight of draw-bar box.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
