Moving up and down for connecting rod and move up and down, the top vertical bar 3a1 is equipped with upper boom 3a11 and lower beam 3a12, and connecting rod 2c is disposed vertically
Between upper boom 3a11 and lower beam 3a12, realize that vertical bar 3a1 moves up and down with the up and down motion of connecting rod 2c；Fixed sliding block
3a2 includes the cylinder 3a22 on bottom plate 3a21 and bottom plate, and cylinder 3a22 can be along guide groove relative motion；
Guide groove 3b as shown in Figure 6 is laterally arranged along each drawer body side plate, drawer body is arranged in vertical bar 3a1
The same side is connected with horizontal guide slot 3b2 by upward slope guide groove 3b1 and is formed, and horizontal guide slot 3b2 connection upward slope guide groove
3b1 higher end, vertical bar 3a1 are positioned close at the lower one end upward slope guide groove 3b1, convenient for the fixation sliding block 3a2 on vertical bar
Into and out guide groove, upward slope guide groove 3b1 are made of ramp 3b11, lower inclined plane 3b12 and lower plane 3b13, ramp
3b11 is arranged in parallel in above lower inclined plane 3b12, and the spacing and fixed sliding block between upper lower inclined plane are to matching, and ramp 3b11 is under
The higher end of inclined-plane 3b12 is connect with the upper surface of horizontal guide slot 3b2 3b21 and following 3b22 respectively, realizes seamless interfacing, under
The lower one end inclined-plane 3b12 is connect with the one end lower plane 3b13, the outside horizontal extension of the lower plane 3b13 other end, the distance of extension
Match with the length of fixed sliding block, accepts fixed sliding block 3a2 convenient for lower plane, limit plate 3c is arranged in upward slope guide groove 3b1
The top end of lower one end, and it is parallel with fixed sliding block 3a2, in locking state, fixed sliding block 3a2 and limit plate 3c is closely connect
Touching prevents the i.e. fixed sliding block of the relative motion of upward slope guide groove cannot be along guide groove relative motion, so that drawer can not be opened, in fact
Now lock；
Connecting plate 3d is equipped on the side of the top and limit plate 3c of lower plane 3b13 close to side plate of the drawer, it is convenient logical
Cross the connection between connecting plate 3d realization guide groove and side plate of the drawer.
As depicted in figs. 1 and 2 in locking state, it is in close contact on the right side of fixed sliding block 3a2 with limit plate 3c, prevents guiding
The relative motion of slot, and the fixed bottom end sliding block 3a2 can be to moving down apart from upward slope guide groove bottom end, that is, lower plane distance and vertical bar
Dynamic is equidistant, so that fixed sliding block 3a2 is moved on lower plane 3b13 with vertical bar 3a1, when unlocked, fixed sliding block
3a2 is displaced downwardly in upward slope guide groove 3b1 with vertical bar 3a1, along upward slope guide groove 3b1 and horizontal guide slot 3b2 relative motion；
Synchronization mechanism as shown in Figure 9 and Figure 10 includes the rack gear 4a and synchronizing shaft 4b being arranged on cabinet body inner sidewall, synchronous
The both ends of axis 4b are equipped with gear 4c, gear 4c and rack gear 4a engagement, and gear 4c is along rack movement；Synchronizing shaft 4b is arranged in each pumping
At the back plate outer wall of drawer ontology, make to form U-shaped structure between rack gear 4a and synchronizing shaft 4b, rack gear 4a, gear 4c and synchronizing shaft 4b match
It closes, realizes that drawer body two sides side plate is drawn out or pushes back together, avoid drawer body two sides from the uneven problem in front and back occur, guarantee
The synchronism and stability of drawer drawer body two sides when pulling open or pushing back, extends the service life of drawer.
The optimum positional relationship of vertical bar 3a1 and guide groove 3b1 is to be vertically arranged, convenient for the fixation sliding block 3a2 on vertical bar 3a1
Into and out guide groove 3b, or moved in guide groove 3b.
It is fixed with the annulus 4d that synchronizing shaft passes through on the back plate outer wall of each drawer body, is used to support synchronous with restriction
Axis.
The uphill angle of upward slope guide groove 3b1 is 20-45 °, and best angle is 36 °, is led convenient for fixed sliding block 3a2 in upward slope
It is moved up into slot 3b1.
Locking device as depicted in figs. 1 and 2 is in close contact on the right side of fixed sliding block with limit plate in locking state, so that
Guide groove is fixed sliding block and blocks, and realizes the locking of drawer；Key is inserted into lock core rotation, and connecting rod, which rotates with it, to be moved down,
Unlocking the vertical link lock of cabinet body side, i.e., vertical link lock moves down, and fixed sliding block is moved as vertical bar moves down,
Guide groove be not fixed sliding block blocking, so that each drawer is unlocked；
As shown in Figure 3-Figure 5 in unlocking process, distance due to fixed sliding block bottom end apart from upward slope guide groove bottom end with
What vertical bar can move down is equidistant, fixed sliding block in vertical bar moves downwardly to each corresponding upward slope guide groove i.e. under
In plane, any one drawer is pulled open, as drawer is opened, fixes sliding block along the upward slope guide groove and level of drawer side surface
Guide groove is mobile, since the position of horizontal guide slot is higher than upward slope guide groove, so that the vertical bar of vertical direction moves up, vertical bar
On other fix sliding blocks and move up therewith, be in close contact with corresponding limit plate, so that other drawers for not being opened
Again it locks, other drawers can not be opened at this time, realize the function of opening the locking of other drawers of drawer.
It is emphasized that: the above description is only the embodiments of the present invention, is not intended to limit the utility model
The scope of the patents, equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, or it is straight
It connects or is used in other related technical areas indirectly, be also included in the patent protection scope of the utility model.
