Technique effect of the present utility model is: the utility model product structure is simple, reasonable in design ingenious, by rail in slide rail being arranged the shifting block that can stir up and down and the unblock block assembly with shifting block interlock, realize locking and the unblock of slide rail, improve reliability during product work.
Accompanying drawing explanation
Fig. 1 is exploded perspective view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
In Fig. 1, comprise and separate bending 21, draw-in groove 22 etc. in lock dog 1, first rivet 2, solution lock dog torsion spring 3, contiguous block 4, shifting block torsion spring 5, second rivet 6, gum cover 7, shifting block 8, driving rivet 9, interior rail 10, interior rail bending 11, bending boss 12, middle rail gear point 13, outer rail 14, middle rail 15, first projection 16, second projection 17, first kidney slot 18, second kidney slot 19, the outer bending 20 of shifting block, shifting block.
As shown in Figure 1, the utility model is a kind of railroad, comprise outer rail 14, outer rail 14 chute to be slidably connected middle rail 15 by a pearl seat retainer, middle rail 15 chute is slided by another pearl seat retainer and arranges interior rail 10, also comprise contiguous block 4, separate lock dog 1, shifting block 8, described contiguous block 1 one end forms the first projection 16, and the other end forms the second projection 17; Separate lock dog 1 two ends symmetry and offer the first kidney slot 18 longitudinally arranged, separating lock dog 1 is connected on interior rail 10 by the first rivet 2 through the first kidney slot 18, be provided with between solution lock dog 1 and interior rail 10 and separate lock dog torsion spring 3, torque arm end, described solution lock dog torsion spring 3 side is connected in the connecting hole separated on lock dog 1, and opposite side torque arm is resisted against on middle rail 15 frame inner wall; Described second projection 17 offers the second kidney slot 19 of lateral arrangement, shifting block 8 is connected on interior rail 10 by the second rivet 6 through the second kidney slot 19, shifting block torsion spring 5 is sheathed on the second rivet 6, a torque arm of described shifting block torsion spring 5 is arranged in the groove at shifting block 8 edge, another torque arm is resisted against on interior rail 10 frame, the inside and outside two ends of shifting block 8 are respectively arranged with bending 21 in shifting block, the outer bending 20 of shifting block, on described shifting block 8, riveted joint has driving rivet 9, drives rivet 9 to be arranged in the through hole of contiguous block 4 end; Described interior rail 10 end is provided with interior rail bending 11, and interior rail bending 11 matches with the draw-in groove 22 on shifting block 8; Outer rail 14 end forms bending boss 12, and when slide rail cuts out, shifting block 8 matches with bending boss 12.
The outer bending 20 of described shifting block is arranged with gum cover 7, in use, realizes unlocking the object with locking by pressing gum cover 7, the effect of pressing handle is played in the outer bending 20 of shifting block.
Described first projection 16 is positioned at the groove separating lock dog 1, the first projection 16 is provided with the through hole of triangle; Rail gear point 13 during middle rail 15 is provided with corresponding to interior rail bending 11 place, separate lock dog 1 middle part and form a link slot, this link slot and middle rail keep off and a little 13 being used in combination.
The course of work of the present utility model is as follows: the utility model product operationally, is installed on drawer by correct way.Slide rail in off position, shifting block 8 is interfered with the bending boss 12 on outer rail 14, ensure that slide rail is in the lock state after cutting out, when stirring shifting block 8, shifting block 8 is interfered with the interior rail bending 11 on interior rail 10, be in released state, now slide rail can pull out, but keeps off a little 13 also there is interference because separating lock dog 1 and middle rail, and slide rail is non-disconnectable to be drawn off, when applying external force to shifting block 8, shifting block 8 can pass over interior rail bending 11, continues to drive contiguous block 4 to drive solution lock dog 1 to move downward, thus crosses middle rail gear point 13, arming device state, interior rail 10 is removable to be drawn off.
Because solution lock dog 1 keeps off a little 13 interference place with middle rail, inclined-plane is set, slide rail is opened with time closed, without the need to pulling shifting block 8, slide rail can easily pull out, when when released state, unclamp shifting block 8, separate lock dog 1 and snap in middle rail gear point 13, slide rail will remain on pull-out state, and needing to stir shifting block 8 could continue pull-out or close by slide rail; This device is reliable, safe ready, and the safeties especially increased, can prevent maloperation.
