Description
Technical field
The utility model belongs to furniture and uses the metal parts field, is involved in to be used for the buffer unit that drawer is closed automatically.
Technical background
Present drawer buffer unit is 200920051465.4 drawer buffer like the patent No., and this buffer occupancy space is big; Thereby influence the serviceability of drawer, and for example the patent No. is the buffer unit of pass certainly of 200920264557.0 drawer guideway, though solve the problem that takies large space; But owing to have only chute on the slide plate, movable rail of drawer guideway and slide plate do not interfix, when causing using; The difficult entering chute of the movable rail of drawer guideway; And be easy to break away from slide plate, structural instability, thus influence result of use.
The utility model content
In order to overcome the defective of above-mentioned drawer buffer unit, the utility model provides a kind of use simple, and constitutionally stable drawer is used buffer unit.
Drawer is used buffer unit, includes fixed guide, sliding rail, holder, sliding part and pulling spring and air pressure or hydraulic cushion push rod, it is characterized in that: the end below of described sliding rail is provided with a promotion projection and both sides are provided with a recess; Holder is provided with a gathering sill; A chucking knuckle groove is arranged in this gathering sill porch, and sliding part is provided with a rotation slot and both sides and respectively is provided with a fixing projection, is movably installed with a slide fastener on the rotation slot; This slide fastener one side is provided with fixedly projection; Opposite side is provided with the guiding projection, and slide fastener one end is provided with one and promotes projection, and the other end is provided with the fastening projection.
Above-mentioned air pressure or hydraulic cushion push rod are processed for the stainless iron metal material.
Above-mentioned promotion projection is one square, and this square less than the space that promotes between projection and the fastening projection.
Above-mentioned chucking knuckle groove becomes 80 ° of-90 ° of angles with gathering sill.
The beneficial effect of the utility model
Because spring of the utility model and hydraulic pressure or pressure buffer push rod are for laterally arranging; More can practice thrift usage space for this reason; The convenient use; And hydraulic pressure or pressure buffer push rod are processed with the stainless iron metal material, have avoided prior art to be mostly that plastics are processed because of intensity, precision and have produced the defective of gas leakage, leakage of oil inadequately.And be provided with fixedly projection in the sliding part both sides and the sliding rail both sides respectively are provided with and the fixing corresponding recess of projection; More compact when this buffer unit is used, stable, sliding part gets into the gathering sill of holder more smoothly; Thereby more light when using, noise is littler.

The specific embodiment
The drawer extremely shown in Figure 5 like Fig. 1 includes fixed guide 1, sliding rail 2, holder 3, sliding part 4 and pulling spring 5 and hydraulic pressure or pressure buffer push rod 6 with buffer unit.This holder 3 is fixed on the fixed guide 1, and pulling spring 5 and hydraulic pressure or pressure buffer push rod 6 are installed on the holder 3 and are connected with sliding part.This air pressure or hydraulic cushion push rod 6 are processed by the stainless iron metal material.Sliding rail 2 one ends below is provided with a square promotion projection 7 and respectively is provided with a recess 8 with both sides; Holder 3 centre positions are provided with a gathering sill 9; One 80 °-90 ° chucking knuckle grooves 10 are arranged in these gathering sill 9 porch, and sliding part 4 is provided with a rotation slot 11 and both sides and respectively is provided with a fixing projection 14, is movably installed with a slide fastener 15 on the rotation slot 11; These slide fastener 15 1 sides are provided with fixedly projection 14; Opposite side is provided with guiding projection 15, and slide fastener 13 1 ends are provided with one and promote projection 16, and the other end is provided with fastening projection 17.The size that promotes projection 7 is less than the space that promotes between projection 16 and the fastening projection 17.
When the utility model uses; Move to fixed guide 1 as long as promote sliding rail 2, through the rotation slot 11 of the 7 entering sliding parts 4 of the promotion projection under the sliding rail 2, the recess 8 of sliding rail 2 blocks the fixedly projection 14 of sliding part 4 both sides; Make sliding rail 2 be difficult for breaking away from sliding part 4; Simultaneously, promote projection 7 and stir the promotion projection 16 of slide fastener 15, making slide fastener 15 is that the center rotates with fixing projection 14; Fastening projection 17 rotates up and breaks away from chucking knuckle groove 10; Make to promote to form a mobile draw-in groove between projection 16 and the fastening projection 17, promote projection 7 and promote the gathering sill 9 that sliding part 4 gets into holder 3, form automatic closed condition through this draw-in groove.Otherwise the fastening projection 17 of the promotion projection 7 pulling slide fastener 13 under the sliding rail 2 forms opening.
