Description
Technical field
The utility model relates to the technical field of slide rail, is specially a kind of improved slide rail from returning structure.
Background technology
In the technical field of slide rail, the frequent pull of slide rail, close, the pull of the slide rail that particularly loading capacity is larger, close, for the stability that slide rail cuts out, the normal slide rail that adopts is from returning structure on slide rail, and existing slide rail is from returning in the structure, complex structure, arrange separately from returning clamping block, this setup causes slide rail from returning the unstable of locking so that the clamping block position wanders off easily.
Summary of the invention
For the problems referred to above, the utility model provides a kind of improved slide rail from returning structure, can be preferably to having guaranteed that slide rail is from the stability of returning locking.
Its technical scheme is such, a kind of improved slide rail is from returning structure, it comprises rail in slide rail outer rail and the slide rail, be provided with base on the described slide rail outer rail, it is characterized in that: be provided with L shaped guide groove on the described base, sliding shoe connects described base by extension spring, and movable riveted joint has the centering block with groove on the described sliding shoe, be provided with the guide pillar that cooperates with described L shaped guide groove on the free movable end of described centering block, be provided with the shifting block with described centering block groove fit in the described slide rail on the rail.
It is further characterized in that: described sliding shoe connects base by the extension spring that is arranged on the lateral slot of base both sides; The free movable end of described centering block is the trapezoidal shape with the inclined-plane; The one side of described groove is the inclined-plane; Described L shaped guide groove comprises guide groove elongated slot section and guide groove bending section, form installation bullet piece with described guide groove bending section homonymy on the described base, the opening of described installation bullet piece is less than the diameter of described guide pillar, and the lower surface of the upper surface of described installation bullet piece and described guide groove elongated slot section is on a plane.
In the said structure of the present utility model, owing to be provided with L shaped guide groove on the base, sliding shoe links base by extension spring, movable riveted joint has the centering block with groove on the sliding shoe, be provided with the guide pillar that cooperates with L shaped guide groove on the free movable end of centering block, be provided with the shifting block with the centering block groove fit in the slide rail on the rail, when rail slides in the slide rail, shifting block enters in the centering block groove, the centering block rotation, guide pillar on the centering block enters the elongated slot section of L shaped guide groove, by the pulling force of extension spring sliding shoe, centering block is drawn in the guide rail end together with rail in the slide rail, has realized the stable closure of certainly returning of guide rail.
Description of drawings
Fig. 1 is that the improved slide rail of the utility model is from the structural representation that returns structure;
Fig. 2 is the mounting structure figure of shifting block;
Fig. 3 is that improved slide rail is from the working state figure that returns structure.
The specific embodiment
See Fig. 1, Fig. 2, Fig. 3, a kind of improved slide rail is from returning structure, it comprises slide rail outer rail 2, rail 9 in the slide rail, base 1 is arranged on the slide rail outer rail 2, be provided with L shaped guide groove 3 on the base 2, L shaped guide groove 3 comprises guide groove elongated slot section 13 and guide groove bending section 12, base is provided with lateral slot on 2 both sides, sliding shoe 4 tangles step 18 on the base 1 by the extension spring 5 that is arranged on base both sides lateral slot 17, movable riveted joint has the centering block 6 with groove on the sliding shoe 4, the one side of groove 10 is the inclined-plane, the free movable end 7 of centering block 6 is the trapezoidal shape with the inclined-plane, be provided with the guide pillar 8 that cooperates with L shaped guide groove 3 on the free movable end 7 of centering block 6, be provided with the shifting block 11 that cooperates with centering block groove 10 on the rail 9 in the slide rail, form installation bullet piece 14 with guide groove bending section 12 homonymies on the base 1, the opening 15 of bullet piece 14 is installed less than the diameter of guide pillar 8, the upper surface 16 of installation bullet piece 14 and the lower surface of guide groove elongated slot section have guaranteed guide pillar being free to slide on L shaped guide groove 3 on a plane.
Illustrate that below in conjunction with Fig. 1, Fig. 2, Fig. 3 the improved slide rail of the utility model returns the operation principle of structure certainly:
See Fig. 1, Fig. 2, the slide rail opening procedure: rail 9 is together with shifting block 11 motions in the slide rail, shifting block 11 drives centering block 6, centering block 6 drives sliding shoe 4, sliding shoe 4 overcomes the pulling force of spring, by the guide pillar 8 on the centering block 6 under the guiding of L shaped guide groove 3, driving centering block 6 moves along L shaped guide groove 3, groove 10 on the centering block 6 drives rail 9 motions in the slide rail by the shifting block 11 on the rail 9 in the slide rail, when guide pillar 8 moved to guide groove bending part 12 on the L shaped guide groove 3, centering block 6 was by the effect of self gravitation, centering block 6 rotations, shifting block 11 skids off the groove 10 on the centering block 6, and the interior rail 9 of realization slide rail separates with centering block 6.Slide rail closing process: when rail 9 moves to guide groove bending part 12 on the L shaped guide groove 3 in the slide rail, shifting block 11 enters in the groove 10 on the centering block 6, when rail 9 continues motion in the slide rail, centering block 6 is rotated counterclockwise, guide pillar 8 on the centering block 6 leaves the guide groove elongated slot section 13 that the guide groove bending part 12 on the L shaped guide groove 3 enters L shaped guide groove 3, effect by spring 5, sliding shoe 4, centering block 6 is drawn in the guide rail end together with rail in the slide rail 9, realized the stable closure of certainly returning of guide rail, improved slide rail has guaranteed in the approaching situation in closed position from returning structure, the slide rail drives drawer returns naturally, it is tight to have guaranteed that drawer is closed, and is particularly useful for the reach in freezer of refrigerator, and the prevention refrigerator doors is closed in the not tight situation, compressor is worked always, wastes energy and the easy compressor that damages.
The one side of groove 10 is the inclined-plane, and the free movable end 7 of centering block 6 is the trapezoidal shape with the inclined-plane, and it is happier to make shifting block 11 enter and skid off groove 10.
At erection stage, because shifting block and groove be respectively on different parts, put into the process of groove at shifting block, by the distortion of bullet piece is installed, so that shifting block is fit in the groove is convenient.
This improved slide rail is applicable to the situation of slide rail left hand and the right hand from time structure.
