Description
Technical field
The present invention relates to the technical field of drawer sliding rail, be specially the automatic recycling device for drawer sliding rail.
Background technology
In existing sliding rail structure of drawer, most drawer is not shifted the automatic recovery function after certain position onto, cause the omnidistance applied thrust of user's needs just can make drawer close fully, when exerting oneself when excessive, easily cause drawer and cabinet partly to form collision, drawer even can rebound, and the long-time casing of operation like this is fragile; When exerting oneself when too small, drawer can not be closed fully, especially for the drawer in refrigerator, easily causes that in casing, preservation object contacts with ambient gas, can not reach the preservation requirement.
Summary of the invention
For the problems referred to above, the invention provides the automatic recycling device for drawer sliding rail, it makes the user promote drawer can complete the automatic recovery to drawer sliding rail after certain position, guarantees closing of drawer, and the user uses time saving and energy saving.
Automatic recycling device for drawer sliding rail, its technical scheme is such: it comprises fixed guide, rail plate, described fixed guide is anchored on the main part of cabinet, described rail plate is fixed in drawer, it is characterized in that: the rear end of described fixed guide is equipped with the elastic guide seat, the end pedestal of described elastic guide seat is anchored on described fixed guide, the targeting part of described elastic guide seat is arranged along the direction of fixed guide, described targeting part has gathering sill, the front end of described gathering sill is provided with elasticity traveller positioning chamber, elastic slide block is embedded in the guide rail of described fixed guide, be provided with extension spring between the both sides between the end of described elastic slide block and described end pedestal, the stylolitic part of elasticity traveller is installed in the circular arc long slot bore of described elastic slide block, the straight line projective structure of described elasticity traveller is positioned at described gathering sill, described stylolitic part evagination is in described elastic slide block, the rear end of described rail plate is provided with shifting block, described shifting block is provided with the lock-bit skewed slot, transfer to projection, described lock-bit skewed slot is positioned at the protruding front portion of described dial-out, under the drawer closure state, described stylolitic part is installed in open lock-bit skewed slot, transition between described lock-bit skewed slot and dial-out projection is the arc transition structure.
It is further characterized in that: it also comprises the guide rail extension arm, and described guide rail extension arm is flush-mounted in described fixed guide, and described rail plate is flush-mounted in described guide rail extension arm;
Described shifting block also has traction grooved, and described traction grooved is positioned at the protruding rear portion of described dial-out, and the rear portion of described traction grooved is provided with the guide tongue header structure, and the rear portion of described guide tongue header structure is the structure closed up to the bottom outer wall of traction grooved from back to front.
After adopting the present invention, under the drawer closure state, the lock-bit skewed slot of shifting block blocks stylolitic part, when rail plate is extracted out, the lock-bit skewed slot drives the stylolitic part reach, it drives the straight line projective structure and moves forward along gathering sill, and then drive elastic slide block reach, extension spring stretches, end when stylolitic part moves to gathering sill foremost afterwards, after being elasticity traveller positioning chamber, it can't move forward again, now shifting block continues forward, stylolitic part is final to transfering to projection along the rear structure transition of lock-bit skewed slot, transfer to projection that stylolitic part is transferred to along the circular arc long slot bore, now straight line projective structure skew, be positioned in elasticity traveller positioning chamber, now extension spring is in elongation state, rail plate continues to extract out afterwards, open drawer, when drawer when open mode need to be closed, promote rail plate, shifting block backward, make the inclined-plane of lock-bit skewed slot contact with stylolitic part, finally stylolitic part is retracted, and then make the straight line projective structure recover vertical, the straight line projective structure is loaded in gathering sill, under the pulling force effect of extension spring, elastic slide block is pulled, now the people does not need to exert all one's strength, the position of stylolitic part is locked in the inside of lock-bit skewed slot and drives rail plate and completes the automatic recovery, until extension spring recovers deflated state, it makes the user promote drawer can complete the automatic recovery to drawer sliding rail after certain position, guarantee closing of drawer, the user uses time saving and energy saving.

The specific embodiment
See Fig. 1～Figure 10, it comprises fixed guide 1, rail plate 2, fixed guide 1 is anchored on the main part of cabinet, rail plate 2 is fixed in drawer, the rear end of fixed guide 1 is equipped with elastic guide seat 3, the end pedestal 4 of elastic guide seat 3 is anchored on fixed guide 1, the lead part 5 of elastic guide seat 3 is arranged along the direction of fixed guide 1, lead part 5 has gathering sill 6, the front end of gathering sill 6 is provided with elasticity traveller positioning chamber 7, elastic slide block 8 is embedded in the guide rail of fixed guide 1, be provided with extension spring 9 between the both sides that the end of elastic slide block 8 and end pedestal are 4, the stylolitic part 11 of elasticity traveller 10 is installed in the circular arc long slot bore 12 of elastic slide block 8, the straight line projective structure 13 of elasticity traveller 10 is positioned at gathering sill 6, stylolitic part 11 evaginations are in elastic slide block 8, the rear end of rail plate 2 is provided with shifting block 14, shifting block 14 is provided with lock-bit skewed slot 15, transfer to projection 17, described lock-bit skewed slot 15 is positioned at the described front portion of transfering to projection 17, under the drawer closure state, described stylolitic part 11 is installed in open lock-bit skewed slot 15, the transition that described lock-bit skewed slot 15 and dial-out projection are 17 is the arc transition structure.It also comprises guide rail extension arm 18, and guide rail extension arm 18 is flush-mounted in fixed guide 1, and rail plate 2 is flush-mounted in guide rail extension arm 18.Shifting block 14 also has traction grooved 16, described traction grooved 16 is positioned at the described rear portion of transfering to projection 17, the rear portion of described traction grooved 16 is provided with guide tongue header structure 19, and the rear portion of described guide tongue header structure 19 is the structure closed up to the bottom outer wall of traction grooved from back to front.
Wherein, when elasticity traveller 10 accidents skid off, due to stylolitic part 11 not in the control space of shifting block 14, now rail plate 2 rolls back after pulling out again, whole device can not work, now continue to advance rail plate 2, shifting block 14 moves inward with rail plate 2, the front end of shifting block 14 presses to stylolitic part 11 at the rear portion of guide tongue header structure 19, because the rear portion of guide tongue header structure 19 is the structure closed up to the bottom outer wall of traction grooved from back to front, oppressed and the displacement of stylolitic part 11, until stylolitic part 11 is displaced in traction grooved 16, now in the control space of elasticity traveller in shifting block 14, stylolitic part 11 is stuck in traction grooved 16 along with traction grooved is drawn out, and by the tip of guide tongue header structure 19, stylolitic part 11 is released, 13 skews of straight line projective structure, be positioned in elasticity traveller positioning chamber 7, promote again afterwards rail plate 2, because straight line projective structure 13 is positioned elasticity traveller positioning chamber 7, be the control space of the stylolitic part 11 of elasticity traveller 10 at shifting block 14, follow-uply complete normal drawer closed action, make the user promote drawer and can complete the automatic recovery to drawer sliding rail after certain position, guarantee closing of drawer, the user uses time saving and energy saving.
