Description
Technical field
The present invention relates to the technical field of slide rail, be 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 bigger, 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; Be provided with separately from returning clamping block, this set mode makes the clamping block position wander off easily, causes slide rail from the instability of returning locking.
Summary of the invention
To the problems referred to above, the invention 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, and a kind of improved slide rail is from returning structure, and it comprises rail in slide rail outer rail and the slide rail; Said slide rail outer rail is provided with base; It is characterized in that: said base is provided with L shaped guide groove, and sliding shoe connects said base through extension spring, and movable riveted joint has the centering block of band groove on the said sliding shoe; The free movable end of said centering block is provided with the guide pillar that cooperates with said L shaped guide groove, and the interior rail of said slide rail is provided with the shifting block with said centering block groove fit.
It is further characterized in that: said sliding shoe connects base through the extension spring that is arranged on the lateral slot of base both sides; The free movable end of said centering block is the trapezoidal shape on band inclined-plane; The one side of said groove is the inclined-plane; Said L shaped guide groove comprises guide groove elongated slot section and guide groove bending section; Form installation bullet piece with said guide groove bending section homonymy on the said base; The opening of said installation bullet piece is less than the diameter of said guide pillar, and the lower surface of the upper surface of said installation bullet piece and said guide groove elongated slot section is on a plane.
In the said structure of the present invention, because base is provided with L shaped guide groove, sliding shoe is through extension spring link base; Movable riveted joint has the centering block of band groove on the sliding shoe, and the free movable end of centering block is provided with the guide pillar that cooperates with L shaped guide groove, and the interior rail of slide rail is provided with the shifting block with the centering block groove fit; When rail slides in the slide rail; Shifting block gets in the centering block groove, the centering block rotation, and the guide pillar on the centering block gets into the elongated slot section of L shaped guide groove; Pulling force through extension spring is drawn in the guide rail end to sliding shoe, centering block together with rail in the slide rail, has realized the stable closure of returning certainly of guide rail.
Description of drawings
Fig. 1 is the structural representation of the improved slide rail of the present invention from time 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, and it comprises rail 9 in slide rail outer rail 2, the slide rail; Base 1 is arranged on the slide rail outer rail 2, and base 2 is provided with L shaped guide groove 3, and L shaped guide groove 3 comprises guide groove elongated slot section 13 and guide groove bending section 12; Base 2 both sides are provided with lateral slot, and sliding shoe 4 tangles the step 18 on the base 1 through the extension spring 5 that is arranged on base both sides lateral slot 17, and movable riveted joint has the centering block 6 of band 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 on band inclined-plane, and the free movable end 7 of centering block 6 is provided with the guide pillar 8 that cooperates with L shaped guide groove 3, and rail 9 is provided with the shifting block 11 that cooperates with centering block groove 10 in the slide rail; Form installation bullet piece 14 with guide groove bending section 12 homonymies on the base 1; The diameter of the opening 15 of bullet piece 14 less than guide pillar 8 is installed, and 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.
Below in conjunction with Fig. 1, Fig. 2, Fig. 3 the operation principle of the improved slide rail of the present invention from time structure is described:
See Fig. 1, Fig. 2, the slide rail opening procedure: rail 9 is together with shifting block 11 motions in the slide rail, and shifting block 11 drives centering block 6; Centering block 6 drives sliding shoes 4, and sliding shoe 4 overcomes the pulling force of spring, through the guide pillar on the centering block 68 under the guiding of L shaped guide groove 3; Drive centering block 6 and move along L shaped guide groove 3, the groove 10 on the centering block 6 drives rail 9 motions in the slide rail through the shifting block on the rail 9 in the slide rail 11, when guide pillar 8 moves to the guide groove bending part 12 on the L shaped guide groove 3; Centering block 6 is through 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 closes closed procedure: when rail 9 moves to the guide groove bending part 12 on the L shaped guide groove 3 in the slide rail, in the groove 10 that shifting block 11 gets on the centering block 6, when rail 9 continues motion in the slide rail; Centering block 6 is rotated counterclockwise, and the 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 gets into L shaped guide groove 3, through the effect of spring 5; Sliding shoe 4, centering block 6 are drawn in the guide rail end together with rail in the slide rail 9, have realized the stable closure of returning certainly of guide rail, and improved slide rail has guaranteed under 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 under 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 on band inclined-plane, and it is happier to make shifting block 11 get into 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, through the distortion of installation bullet piece, it is convenient to make that shifting block is fit in the groove.
This improved slide rail is applicable to the situation of the slide rail left hand and the right hand from time structure.
