Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
Referring to Fig. 1, Fig. 2, the utility model provides a kind of draw-bar box to have casing 2 and pull bar 1, and two relative sides 5 that are positioned at the casing 2 of described pull bar 1 both sides are the bridge shape arcwall face to casing outside projection; The raised points of described arcwall face is at the middle part of casing side; At inner casing interior angle 3 places near box top 6 of casing 2, be provided with laminar corner protector 7.
Shown in Figure 3, as an embodiment, the difference in height between whole cambered surface peak and the minimum point of the arcwall face of the utility model box body of draw-bar box 2 sides 5 is less than or equal to 7mm." h " marking in Fig. 3 represents the difference in height between peak and minimum point.
Hard draw-bar box is in the long-term process using, and casing side 5 is along with continuous extruding meeting is more easily caved in to box inside.The arcwall face of the capable shape of bridge outwards arching upward is made in side 5, and in the time being subject to external force extruding, can both there be certain buffering side 5 to external force, thereby has solved casing side 5 depression problem in use for some time each time.
Shown in Fig. 4, Fig. 5, as an embodiment, described corner protector 7 comprises the spoon shape curved face part 13 of fitting completely with described casing interior angle 3 tops and the symmetrical arc face 12 of fitting with casing side 5 and end face 6 intersections; On the inner concave of described spoon shape curved face part 13, be provided with reinforcement 8.
Draw-bar box is in transport and use procedure, and four jiaos is to be the most easily squeezed and impaired, and described spoon shape curved face part 13 and symmetrical arc face 12 make the corner protector 7 that is arranged on interior angle 3 to fit seamless completely with casing 2 inwalls.
In certain embodiments, corner protector 7 can be fixed on by mode bonding or that sew up interior angle 3 places of casing 2.Fixed form can be single, can be also the uses that combine of two kinds of fixed forms, and as shown in Figure 2, one of them embodiment is that suture 11 is located at the wider one end of fan-shaped corner protector 7.
Shown in Figure 3, as an embodiment, described corner protector 7 is the narrow fan shape in wide one end, one end.Adopt fan shape structure, can reach the object of saving material, reducing costs.
As an embodiment, described reinforcement is the forked reinforcement that comprises many strip shape bodies; Described many forked reinforcement 8 one end openings, other end sealing; Described opening is towards the wide one end of fan-shaped corner protector 7.Concrete, reinforcement 8 quantity can have five, and three of inner sides are W type, and the formation of two, outside is U-shaped, and the W type reinforcement of inner side is nested in the capable reinforcement of outside U, and opening direction is consistent.Between inner side and the reinforcement in outside, be provided with a vertical reinforcement.
Reinforcement 8 can increase intensity and the pliability of corner protector, and in the time that casing 2 is subject to stronger external impacts, corner protector 7 can reach the object of alleviating impulsive force in casing 2 inner sides, and reinforcement 8 makes corner protector 7 can bear stronger impulsive force, thus protection casing 2.
Shown in Figure 4, as an embodiment, described corner protector 7 upper ends are provided with corner protector step 10, match with 9 shapes of step in casing.Have casing 2 inner sides of some hard draw-bar boxes can be provided with casing step 9, for corner protector 7 can be fitted completely with casing 2 inwalls, the corresponding position of corner protector 7 step 9 in casing is provided with corner protector step 10.
As an embodiment, described corner protector 7 is provided with at most four, be located at respectively casing 2 end faces 6 four interior angle 3 places.The quantity of corner protector 7, can arrange according to casing material, body structure, in general hard draw-bar box, four corner protectors 7 can be set at most; And common soft draw-bar box can only arrange corner protector at end face 6 near two interior angle 3 places of pull bar 1.
As can be seen from above, the draw-bar box that the utility model provides, two relative sides that are positioned at the casing of described pull bar both sides are the bridge shape arcwall face to casing outside projection; The raised points of described arcwall face is at the middle part of casing side; Casing interior angle place at box house near box top, is provided with laminar corner protector.The radian that casing side arranges has increased the intensity of casing side, and casing side is being subject to not yielding after external force and is caving in to box inside.And corner protector the intensity that has increased by four jiaos of casings is set, make draw-bar box in carrying or use procedure, four jiaos firmer.Meanwhile, be provided with reinforcement in corner protector inner side, increased the solid degree of corner protector, make four jiaos of casings more solid, not fragile.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
