Connecting, the upper outer sheathed stage clip one (8) of front axle (10), this stage clip (8) supports and is located on briquetting (11)；
Operation axle (4) rear end sets gradually interlocking segment (3) and rear door buckling (2), and wherein the upper connection of interlocking segment (3) has with behaviour
Making what axle (4) linked block shaft (12), this block shaft (12) is provided with stage clip two (13) and is supported by stage clip two (13)
Block (14), block shaft (12) is blocked by back door and is suppressed by it；Described snap close (2) and being arranged on back door rises locks back door
The back door locking plate (1) of effect is corresponding, and this back door locking plate (1) is provided with the locked groove corresponding with snap close (2)；
Front side board (7) is provided with and slides up and down part (9), and this slides up and down part (9) and connects handcart guide rail, slides up and down part
(9) block piece being made up of briquetting (11), front axle (10) is spacing.
The interlock that the invention have the advantage that the present invention is mechanical type, and is arranged by structure cleverly, and it has knot
The feature that structure is compact, it mainly uses the mode mechanically linked, it is achieved the cooperation of each associated components, thus realizes only handcart
Falling back on testing position, back door just can be opened, otherwise, only completely closing when back door, handcart could enter the function of operating position,
It has compact conformation, simple and practical, operate the features such as light, life-span length.
Accompanying drawing explanation
Fig. 1,2,3 are in structural representation during manually experiment for the present invention.
Fig. 4,5,6 are in the structural representation of handcart operating position for the present invention.
Figure 1 is back door locking plate, 2 is snap close, 3 is interlocking segment, 4 is operation axle, 5 is fixed block, 6 is fixed support, 7 is
Front side board, 8 for stage clip one, 9 for slide up and down part, 10 be front axle, 11 be briquetting, 12 be block shaft, 13 for stage clip two, 14 for keeping off
Block, 15 be support, 16 for operating handle.
Detailed description of the invention
Present configuration is as follows: support 15 is fixed on rear side of front side board 7, and fixed support 6 is fixed on front side of front side board 7, behaviour
It is separately fixed on front side board 7 and support 15 by fixed block 5 before and after making axle 4.
Operate as follows: handcart, when testing position, is pressed and slided up and down part 9 and expose handle hole, convex by operating handle 16
Play part and be directed at the location notch hole on front side board 7 left side, and push down the front end of front axle 10 update axle 4, be allowed to exit front side board 7
Location notch hole, then rotate clockwise 120 degree, make operating handle 16 bossing alignment front side board 7 on the right of locating slot
Hole, extracts operating handle 16, makes front axle 10 under the pressure effect of stage clip 1, stretches out outside front side board 7, and is fixed on this position
On.Briquetting 11 is pushed down after rotating and is slided up and down part 9 simultaneously, makes to slide up and down part 9 and can not go up shifting.Slide up and down part 9 when moving down, band
The dynamic latch fitting that is associated reaches car guide rail, thus stops handcart to be pushed into operating position from testing position.
Snap close 2, under the rotarily driving of operation axle 4, turns clockwise 120 degree, leaves the locked groove of back door locking plate 1 on back door,
Back door is opened, and block shaft 12 is stretched out outside cabinet under the pressure effect of stage clip 2 13 simultaneously, block 14 with block shaft 12 move to
Interlocking segment 3 is also in same plane, and owing to interlocking segment 3 is blocked by block 14, operation axle 4 can not rotate counterclockwise.
Only completely close when drive back door, back door locking plate 1, push down block shaft 12, and make block 14 stagger with interlocking segment 3,
The bossing of operating handle 16 it is directed at the slotted eye on the right of front side board 7 and pushes down front axle 10, making front axle 10 in the pressure of stage clip 1
Exit the slotted eye on the right under power and rotate 120 degree counterclockwise, being fixed in the slotted eye on its left side, then extract operating handle 16.
Snap close 2, under the rotarily driving of operation axle 4, inserts in the locked groove of back door locking plate 1, pins back door.
After briquetting 11 rotates 120 degree counterclockwise with operation axle 4, it can not be pushed down and slide up and down part 9, slides up and down part 9 and exists
Be associated under the drive of latch fitting upper shifting, drives locking part to exit handcart guide rail, and handcart can be moved to operating position.Due to upper downslide
The locking part that moving part 9 is connected is blocked by the baffle plate on handcart, and sliding up and down part 9 can not be pressed, and therefore this device can not be by
Operation, back door can not be opened.
