Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.

As shown in figs. 1 to 6, many drawers bin drawer interlocking mechanism of the present utility model, comprise be provided with key and lock core tapered end 1, be connected tapered end 1 and linearly extended locking bar 2, the shifting block 3 being located at locking bar 2 extending end, rotating latch 4 and the corresponding latch hook 9 being located at drawer 5 outer wall, shifting block 3 side is provided with the shifting block end 31 of an overshooting shape, locking bar 2 rotates the rotation driving shifting block end 31 to drive latch 4, have in latch 4 rotation process and only have two positions to stop, its section shape is latch hook 9 gib head 91 shape is

Latch 4 is fixedly connected with casing with base member 7 by the seat of honour parts 6 be fixed on casing.

Seat of honour parts 6 comprise one and are affixed merge vertically disposed spring A 8 with locking bar 2 extending end, after the power disappearance of locking bar 2 horizontal movement, are resetted to locking bar 2.

Latch 4 comprises seat 42 under the latch seat of honour 41 being located at upper end and the latch being located at lower end, and the latch seat of honour 41 is connected with the seat of honour parts 6 of casing, and under latch, seat 42 is connected with the base member 7 of casing.

The latch seat of honour 41 comprises upper pedestal 411, the upper axis of rotation 412 be located on upper pedestal 411, spaced fixing catch 413 and active blade 414, spring C 415, upper axis of rotation 412 is assemblied in seat of honour parts 6, active blade 414 can single direction rotation, described spring C 415 is connected with active blade 414, during the stressed rotation of active blade 414, spring C 415 keeps certain pretightning force, after external force disappears, is resetted to active blade 414.

Under latch, seat 42 comprises lower base 421, is located at Shaft 422 on lower base 421 and limit shaft 423, and Shaft 422 is assemblied in base member 7, and limit shaft 423 is active in base member 7, rests on position accurately when latch 4 is rotated.

As shown in Figure 10, base member 7 comprises base body 71, the slide block 72 be located on base body 71, the clamping face 73 be arranged on slide block 72, spring B 74, slide block 72 respect thereto body 71 can slide up and down, spring B 74 makes clamping face fit with limit shaft 423 all the time, and keeps certain pretightning force.

The course of work of many drawers bin drawer interlocking mechanism of the present utility model as shown in figs. 7-9, in normal state, inserting key turns tapered end 1 drives locking bar 2 to rotate, make shifting block end 31 and fixing catch 413 and active blade 414 mating reaction of shifting block 3, thus realize normal locking and unlock, its process is as follows:

Shifting block 3 rotates, and its shifting block end 31 drives active blade 414, makes latch 4 turn to unlocked position, realizes drawer and unlocks; Shifting block 3 rotates (oppositely), and its shifting block end 31 drives fixing catch 413, makes latch 4 turn to locked position, realizes drawer locking, see Fig. 7 and Fig. 8.

When certain drawer of closedown locking, then when the drawer do not closed is forgotten in closedown, because spring A 8 can be compressed, the center of rotation of shifting block 3 can be allowed to offset toward spring A 8 compression direction, latch 4 can normal rotation, and now drawer can be closed smoothly, and can not destroy latch 4.Power due to spring A 8 is greater than the power of the spring B 74 of base member 7, and after this drawer is closed, spring A 8 can make shifting block 3 reset to normal position, thus makes latch 4 rotate to normal locked position.

Movable washer 414 can single direction rotation, its object is to: when locking is in opening, now because abnormal cause makes latch 4 be rotated to the position of locking state, any one drawer cannot be opened, for improving the reliability of this fastening system, active blade 414 is designed to single direction rotation, in these cases, only need rotates key, make shifting block 3 can cross active blade 414 smoothly, whole fastening system is returned to normal locking state, then rotates key and can open, see Fig. 9.

Base member 7 is installed on box bottom, its role is to: provide latch 4 times axial locations; Make latch 4 be in correct position, its implementation procedure is as follows:

Slide block 72 respect thereto body 71 can slide up and down, and spring B 74 makes the clamping face 73 be arranged on slide block 72 fit with limit shaft 423 all the time, and keeps certain pretightning force.Clamping face 73 comprises a middle crest and two, side trough, due to the effect of spring B 74, limit shaft 423 can be made to be in wave trough position all the time, and the position that this two trough is locking and opens, the reliability of fastening system can be ensured like this, see the operating principle schematic diagram of the base member of Figure 11.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.

In addition, be to be understood that, although this manual is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should by manual integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
