The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Existing drawer product has drawer guideway, supporting plate, side plate, back plate and back plate contiguous block.Referring to Fig. 1 to Fig. 3, Fig. 1 is the structure of showing from this left side, drawer product rear portion, and drawer guideway is made up of last rail 9, middle rail and following rail 10, and supporting plate 1 is installed in above the rail 9, side plate 2 shrouds have a plastic back plate contiguous block 4 to be fixed on above the supporting plate 1 of side plate 2 afterbodys in supporting plate 1 outside; Back plate contiguous block 4 stretches out 4 flexible snap close pieces 11 to the right, and these 4 snap close pieces 11 are used for removably connecting with back plate 3 left ends of drawer; End has flanging 12 respectively about back plate 3, and two button holes 13 are arranged on the flanging 12, and when back plate 3 levels were pressed to back plate

contiguous block

4,4 snap close pieces 11 were divided into two groups and pass two button holes 13 after being out of shape respectively and fasten back plate 3 then it is fixed; Obviously, take apart the back need during plate 3 make with external force 11 flexural deformations simultaneously of 4 snap close pieces just can make button hole 13 by figure in the direction of arrow leave back plate contiguous block 4.Secondly, the weight of back plate 3 is applied to downwards by button hole 13 and makes snap close piece 11 bear vertical shearing power for a long time on the snap close piece 11 to be out of shape even to damage.

Referring to Fig. 4 to Fig. 7, the back plate contiguous block 4 of present embodiment is made of plastic, roughly be trapezoidal, there is one to run through top slot 5 vertically downward, below slot 5, be shaped on a upright flexible ratchet 6, the bottom of back plate contiguous block has two projections 14 to be used for a back plate contiguous block clamped to be fixed on supporting plate, and the top of back plate contiguous block has a columniform locating pin 15 to be used for being connected with the side plate afterbody.

Referring to Fig. 8 to Figure 11, the back plate inserted sheet 7 usefulness punching of the steel plate bending of present embodiment forms, it has the grafting plane 16 that a slot 5 with back plate contiguous block matches, and has a through hole 8 on grafting plane 16, and the shape of the flexible ratchet on the shape of through hole 8 and the back plate contiguous block is corresponding; There is cover plate 17 to be used to make back plate inserted sheet to be carried on back plate contiguous block at plate inserted sheet top, back; On the plate inserted sheet of back, also have two installing holes 18 to be used for back plate inserted sheet and back plate are coupled together.

Referring to Figure 12, the slot 5 that back plate contiguous block is aimed on the grafting plane 16 of back plate inserted sheet inserts back plate contiguous block from top to down.

Referring to Figure 13, the grafting plane 16 of back plate inserted sheet makes the deflection to the right of flexible ratchet 6 when running into the flexible ratchet 6 of back plate contiguous block.

Referring to Figure 14, continue to descend in the grafting plane of back plate inserted sheet 16, be lower than the wedge angle lower edge of flexible ratchet 6 to through hole 8 lower edges after, flexible ratchet 6 springs into through hole 8 the grafting plane 16 of back plate inserted sheets is fastened; When the cover plate 17 of back plate inserted sheet 7 contacted the top 20 of back plate contiguous blocks, back plate inserted sheet can not descend again, and all wt of the back plate of back plate inserted sheet and drawer is all born by back plate contiguous block.

Referring to Figure 15, back plate contiguous block 4 is fixed on supporting plate 1 rear portion by two projections, make the slot 5 on the back plate contiguous block 4 parallel, in the locating hole of locating pin 15 embedding side plates 2 afterbodys at plate contiguous block 4 tops, back back plate contiguous block 4 is fused with side plate 2 with the length direction of supporting plate 1; The back plate 3 of drawer is a plate behind the five metals that becomes of a block plate punching out, plate inserted sheet 7 after its two ends respectively are fixed with (right-hand member is not shown in the drawings), after back plate inserted sheet 7 inserts back plate contiguous blocks 4, back plate 3 also with regard to and side plate 2 fused securely.

Referring to Figure 16, with screwdriver 19 stretch into make flexible ratchet and back plate inserted sheet in the plate contiguous block of back through hole separately, can upwards extract back plate 3.Present embodiment only need be pulled a flexible ratchet just can make back plate inserted sheet extract from the plate contiguous block of back, is more convenient compared with the operation of prior art products.

In the present embodiment, the back plate 3 of drawer is a steel plate, and in other embodiment, back plate 3 also can be made with plank, and two installing holes 18 after passing with screw on the plate inserted sheet 7 are fixed on wooden two ends, back plate 3 left and right sides to back plate inserted sheet 7 and get final product.
