In some embodiments of the present utility model, be provided between drawer body 23 and drawer cylinder 22 locking device, Handle and handle positioning device.Locking device includes being arranged at the pivot lock of drawer end cap both sides, is arranged at drawer cylinder 22 On two buckling parts, and clamping promotes device.Each buckling parts can be projection.Clamping promotes device to can be used for promoting two Lock is pivoted to rotate towards the direction (i.e. respective first direction) for being connected in respective buckling parts.Handle horizontal extends, and Drawer end cap can be vertically slidably mounted on.Moreover, when drawer body 23 is closed, residing for handle Position can be the initial position of handle.And handle is configured in its initial position, its two ends pivots lock with two respectively and connect Touch against to prevent each lock that pivots from being rotated along the other direction opposite with respective first direction, so that the pivot Twist lock button keeps mated condition with the buckling parts, so that the drawer body 23 is locked in into the drawer cylinder 22.Enter one Step ground, when handle is moved up or down to holding latched position is released, i.e., is moved to releasing from initial position and keeps locking bit Postpone, each lock that pivots can be allowed to be rotated along the other direction opposite with respective first direction, to allow outside When pulling drawer body 23, pivot lock and rotate the corresponding buckling parts of disengaging, so as to allow to open drawer body 23.Handle is positioned Device is configured to after at the handle motion position predetermined to each, handle is kept at the position, mainly initial Position and releasing keep latched position.When opening drawer body, user first makes handle move to releasing holding lock up or down Positioning is put, and handle positioning device makes handle keep being in the position, and user can outwards pull open drawer body 23.When closing drawer sheet During body, user first closes drawer body 23, then make handle downwards or on return to initial position, handle positioning device makes handle Keep being in the position, so that drawer body 23 and drawer cylinder 22 keep being in the lock state.

In order to further make the stable movement of handle, the two ends of handle are also respectively provided with guide rod and sliding block, guide rod Vertically extend.Drawer body 23 also includes two groups of slideways, the cunning that at least three, every group of slideway vertically extends Groove, so that the both sides of guide rod have a chute respectively, sliding block is moved on remaining chute, or distinguishes the both sides of sliding block With a chute, guide rod is moved on remaining chute.For example, every group of slideway may include before four chutes, guide rod Both sides have a chute respectively afterwards, and the both lateral sides (i.e. the left and right sides) of sliding block have a chute respectively.

So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model many Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the utility model spirit and scope The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new The scope of type is understood that and regarded as to cover other all these variations or modifications.
