Specific embodiment

The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model Protection scope, the pause mark in the utility model indicates the relationship of sum.

As Figure 1-Figure 5, a kind of telescopic bar case, the cabinet of the trolley case provided by the utility model embodiment It is made of upper half box shell, lower half box shell；

The upper half box shell is the shell unidirectionally opened downwards, and upper half box shell is made of upper layer front housing 11, upper layer rear shell 12, Upper layer front housing 11 is hinged in upper layer rear shell 12, and the opposite upper layer rear shell of upper layer front housing energy is opened forward, and upper layer front housing It is equipped with upper layer zipper 31 with the opposite side of upper layer rear shell, upper layer front housing is enabled to pass through 31 phase mutual connection of upper layer zipper with upper layer rear shell It closes；

The lower half box shell is the shell unidirectionally opened upwards, and lower half box shell is made of lower layer's front housing 21, lower layer's rear shell 22, Lower layer's front housing 21 is hinged in lower layer's rear shell 22, and the opposite lower layer's rear shell of lower layer's front housing energy is opened forward, and lower layer's front housing It is equipped with lower layer's zipper 32 with the opposite side of lower layer rear shell, lower layer's front housing is enabled to pass through 32 phase mutual connection of lower layer's zipper with lower layer's rear shell It closes；

The upper half box shell is located at the top of lower half box shell, and vertical upper layer sliding slot 8, mould drag are fixed in upper half box shell Vertical lower layer's sliding rail 9 is fixed on shell, upper half box shell is fitted to down by the track slot of upper layer sliding slot 8 and lower layer's sliding rail 9 In half box shell, upper half box shell is slided up and down with respect to lower half box shell, and the lower ending opening of upper half box shell surrounds lower half The upper end opening of box shell；

Keyhole is offered in the upper half box shell, and movable button 4 is equipped in keyhole, upper layer sliding slot 8 is equipped with locking bar 6, The middle part of locking bar 6 and upper layer sliding slot 8 are pivotally connected, and one end of locking bar 6 and button 4 are affixed, and the other end is towards 9 one lateral bending of lower layer's sliding rail Folding forms latch hook；The multiple lockholes being caught in for the latch hook end of locking bar 6 are offered on lower layer's sliding rail 9, and each lockhole is along perpendicular To being spaced apart, upper layer sliding slot 8 is equipped with for driving the latch hook end of locking bar 6 to be returned towards the mobile locking bar in 9 direction of lower layer's sliding rail Position spring 7.

In the utility model embodiment, the upper half box shell is equipped with lockset 5 for locking upper layer zipper 31, and under After layer 32 drawing of zipper, the cuff link of lower layer's zipper 32 is hidden into upper half box shell, thus when upper layer zipper 31 is not opened, lower layer Zipper 32 can not also pull open, so that lockset 4 can reach in the case where only locking upper layer zipper while lock lower layer's drawing The effect of chain.

In the utility model embodiment, the rear portion of the lower half box shell is equipped with pull rod, and the bottom of lower half box shell is equipped with idler wheel.

The utility model embodiment can adjust size volume according to the quantity of belongings, when the latch hook end of locking bar is caught in down When upper first lockhole on layer sliding rail, cabinet reaches maximum volume；

When needing to adjust tank-volumes, inside button press drives to obtain locking bar pivot, so that the latch hook end of locking bar overcomes lock The elastic force of bar return spring is displaced outwardly, and is deviate from from current lockhole；Upper half box shell can be slided downward or upward at this time, on Half box shell slide downward is to reduce the volume and volume of cabinet, and upper half box shell upward sliding is then the volume and body for expanding cabinet Product, the latch hook end of release button when at the lockhole that upper half box shell slides into target position, locking bar can be in locking bar return spring Elastic force effect under it is mobile towards lower layer's slide direction, be caught in into the lockhole of target position, thus by upper half box shell, mould drag Shell locking.

Pull open upper layer zipper, lower layer's zipper, can pick and place article into cabinet, after article picks and places, by upper layer zipper, Lower layer's zipper distinguishes drawing, i.e., using pull rod and idler wheel dragging cabinet trip.
