From Fig. 1, Fig. 2, can find out, suitcase has pull bar 2 and the handgrip 4 thereof that can pull out or fill in the casing 5, be fixed in the cover plate 1 of casing 5 inner bottom parts in addition, respectively there is a groove cover plate 1 inner face both sides, it is the gusset 11 that profile of tooth is arranged that every groove has one side at least, pull bar 2 lower ends are connecting anti-slow detent mechanism 3, and the locating piece 35 of this mechanism 3 is subjected to the control of the lid of handgrip on the switch handgrip 4 42, from hole 311 outstanding or conceal into.When the handgrip on the depress switch handgrip 4 covers 42, make in the hole 311 of locating piece 35 retraction detent mechanisms 3 pull bar 2 retractables by connecting rod 32.When the handgrip on the trip switch handgrip 4 covered 42, sliding shoe 34 ejected locating piece 35 under the effect of spring 33, was stuck in the tooth of location profile of tooth gusset 11, made pull bar 2 location.As can be seen from Figure 3, the tooth that forms the gusset 11 of one with cover plate 1 on the cover plate 1 is a concave shape, and there is horizontal reinforcement the side of gusset 11.To locate profile of tooth gusset 11 like this and form one, can reduce manufacturing cost, and simplify the internal structure of an organization and prevent and to locate because of the location tooth bar pull bar that causes that gets loose with cover plate 1.As can be seen from Figure 1, pull bar 2 is tubular pull bars that there is locating hole at two ends.Locating hole links together pull bar 2 and detent mechanism 3 and switch handgrip 4.Can find out that from Fig. 2, Fig. 4, Fig. 5 and Fig. 6 anti-slow detent mechanism 3 comprises that the housing 31, the two ends that are fixed on pull bar 2 one ends connect the connecting rod 32 of switch handgrip 4 and sliding shoe 34 respectively, are enclosed within on the connecting rod 32, are stuck in spring 33 between connecting pin 36 and the housing 31, are hinged on the sliding shoe 34 of connecting rod 32 1 ends and are installed in the hole 311 of housing 31 and are stuck in the outer locating piece 35 of sliding shoe 34.Described housing 31 is that one side is porose 311, in addition the two sides have that the location leans on to mould assembly, described hole (311) are square.Described sliding shoe 34, one ends are cylinders that groove, hole are arranged, and the other end is the cuboid that one side has trapezoidal protrusion 341.Described locating piece 35, one side have with gusset 11 on two protrusions 351 adapting of profile of tooth, the trapezoidal protrusion 351 on tooth on the gusset 11 and the locating piece 35 is a circular arc.The another side of locating piece 35 is grooves that trapezoidal protrusion 352 is arranged in.Reference column 312 on the housing 31 is stuck in the locating hole of pull bar termination, and detent mechanism 3 is fixed on the pull bar 2.When the handgrip on the depress switch handgrip 4 covers 42, by connecting rod 32 sliding shoe 34 is moved down, the trapezoidal protrusion 352 of locating piece 35 falls into the recessed portion of sliding shoe 34, in the hole 311 of retraction detent mechanism 3, pull bar 2 retractables.When the handgrip on the trip switch handgrip 4 covers 42, sliding shoe 34 moves up under the effect of spring 33, withstand on by the trapezoidal protrusion 341 of sliding shoe 34 on the position of trapezoidal protrusion 352 of locating piece 35, locating piece 35 is ejected, the protrusion 351 of locating piece 35 is stuck in the tooth of location profile of tooth gusset 11, makes pull bar 2 location.Can find out that from Fig. 2 and Fig. 7 switch handgrip 4 comprises the handgrip body 41 that is fixed on pull bar one end with elasticity fixture block 411, the handgrip that links together with elastic hook 421 and handgrip body 41 covers 42.Described handgrip body 41 has an elasticity fixture block 411 at least in the hole on its both sides, the outside is a groove that boss is arranged, and a hole 412 is arranged above, and described hole 412 is circular, and two cylindrical objects that raise up 41 3 are arranged therebetween.Described handgrip lid 42, at its two ends at least two elastic hooks 421 are arranged respectively, have respectively between two elastic hooks 421 two with handgrip body 41 on the corresponding Cylinder 423 in cylindrical object 413 positions and with handgrip body 41 on the corresponding cylindrical object 422 in 412 positions, hole.41 liang of lateral opening interior elasticity fixture blocks 411 of handgrip body are stuck in the locating hole of pull bar 2 another terminations, and handgrip body 41 is fixed on the pull bar 2.In the cylindrical object 413 that Cylinder 423 on the handgrip lid 42 inserts on the handgrip body 41, play the effect that location and restriction handgrip lid 42 move down distance.The elastic hook 421 that handgrip covers 42 both sides inserts in 41 liang of the handgrip bodies grooves that boss is arranged in lateral opening, and elastic hook 421 cards are blocked by boss, handgrip lid 42 can only be moved down and can not upwards break away from handgrip body 41.One end of connecting rod 32 is by inserting in the hole 412 on the handgrip body 41 in the cylindrical object 422 on the handgrip lid 42.When depressing handgrip and cover 42, connecting rod 32 is depressed, when unclamping handgrip and cover 42, connecting rod 32 covers handgrip 42 jack-up under the effect of spring 33.Because the utility model adopted technique scheme, make the utlity model has that simple in structure, easy to use, detent mechanism is difficult for getting loose, assemble easily, the characteristics of comfortable feel and low cost of manufacture.
