The specific embodiment
Referring to Fig. 1~Fig. 3, concealed drawer buffers has a known damper 1, and damper 1 has plastic cylinder block, piston and damper bar 19, and damper 1 uniaxially when its damper bar 19 moves inwards presents resistance.
Referring to Figure 10, Figure 11, fixed mount 2 is made of plastic, rectangular shaped roughly, be shaped in the one side and have guide groove 9, guide groove 9 is formed by a straightway and one section arc smooth connection, shape as letter " J " is shaped on 4 clamping plate 10 at opposite side, and damper 1 is clamped by clamping plate and is fixed on the fixed mount 2; Fixed mount 2 rear portions have a bayonet socket 11 to be used for mounting spring; 2 cramps 18 and 1 shell fragment 22 are arranged at the bottom of fixed mount 2,2 cramps 18 are put into 2 cramp holes of retaining rail and made them fasten the edge in cramp hole, shell fragment 18 snaps in the shell fragment hole on the retaining rail 2 cramps 18 can not be retreated thereupon, can be installed in fixed mount 2 on the retaining rail 7 apace like this.
Referring to Fig. 8, Fig. 9, sliding part 3 is made of plastic, and is roughly L-shaped, and C shape ring 12, flexing arm 13,14 and 2 projections 15 of hook are arranged on it.C shape ring 12 is used to connect damper connector 4, and its inwall has flange 20; Inwardly deflection during the back pressurized of flexing arm 13; Hook 14 is used to connect spring 5; The width of the diameter of projection 15 and fixed mount 2 guide grooves 9 is suitable, and 2 projections 15 embed guide groove 9 from the front of fixed mount 2; The end of projection 15 has cap 16, and cap 16 is buckled in the bottom surface of guide groove 9.The radial dimension of cap 16 is greater than the width of guide groove 9, can not withdraw from easily after making projection embed guide groove 9.
Referring to Fig. 6, damper connector 4 is made of plastic, it has the cylinder of two mutually orthogonals, one of them cylindrical outer wall has chase 21, it is suitable that the C shape of chase 21 and sliding part 3 is encircled the flange 20 of 12 inwalls, after damper connector 4 is put into C shape ring, can prevent their axial floats between the two; Another cylinder has axis hole 23, the damper connecting rod 19 tight axis holes 23 that insert.
Referring to Fig. 4, Fig. 5, plectrum 6 usefulness punching of the steel plate become, and it has two 17, two shift forks 17 of shift fork that extend can insert in the neutral between the flexing arm 13 of the C shape ring 12 of sliding part 3 and sliding part 3 downwards.Plectrum 6 is welded on the side of movable rail 8 and follows the mobile together (see figure 7) of movable rail 8.Shift fork 17 roof pressures the C shape ring 12 of sliding part 3 or flexing arm 13 and are promoted sliding parts 3 and move together when plectrum 6 moved.
Referring to Fig. 1, spring 5 is spring wire extension springs, the neck that its back coiled diameter shrinks, to the neck of back a little pressure just can make its embed the bayonet socket 11 of fixed mount 2; The front end of spring 5 can be hooked in the hook 14 times of sliding part 3.
Figure 12~Figure 14 shows present embodiment and is pulled outwardly out the variation of mutual alignment between each parts the process from closed condition at drawer.
Referring to Figure 12, drawer is in closed condition, and the piston of damper 1 and damper bar 19 fully move into the rear portion of cylinder, and spring 5 fully shrinks.
Referring to Figure 13, drawer is stressed outwards to be moved, sliding part 3 moves to the front end of guide groove 9, the piston of damper 1 is drawn out of, spring 5 is stretched, this stage last till always projection in front 15 of sliding part 3 walk to be over guide groove 9 straightway immediately under the moment loading that spring 5 applies deflection enter the arc of guide groove 9, sliding part 3 is to next door deflection thereupon, the flexing arm 13 of sliding part 3 leaves plectrum 6, so far the thermal energy storage process of spring 5 finishes, the damper bar 19 of damper 1 is fully extracted out, and sliding part 3 is locked on the inflection point.
Referring to Figure 14, drawer continues outwards to move, and plectrum 6 is followed drawer and moved, and sliding part 3 remains on the latched position.When drawer from the outside when pushing back, its process is opposite with the above-mentioned process of pulling out: the C shape ring 12 that the shift fork 17 of plectrum 6 touches sliding part 3 at first promotes sliding part 3 to make the projection 15 in front to withdraw from the arc of guide groove 9 and enter straightway inward, be pulled to clap at pulling force effect downslide moving part 3, plectrum 6, movable rail 8 and the whole drawer of spring 5 and close the position, in this process, the piston of damper 1 is forced to the cylinder rear portion and is moved, compressed gas gas in the jar when piston moves, slowed down the translational speed of drawer, drawer steadily and is snugly closed fully.
Referring to Figure 15, under following two kinds of situations, sliding part 3 may be in the state that does not have deflection: 1. the erection stage 2. of product has touched sliding part 3 and causes sliding part 3 to reset under deflection state when whole drawer is taken out.When pushing back drawer inside in the case, the shift fork 17 of plectrum 6 at first with the outer side collision of the flexing arm 13 of sliding part 3, at this moment, flexing arm 13 pressurizeds are made flexural deformation, thereby allow shift fork rebulid correct connection.
