Abstract
The utility mode relates to the technical field of sliding rail devices, in particular to a triple folding locking type self-locking sliding rail device, which comprises an outer rail, an intermediate rail and an inner rail which are nested in mutual superposition, wherein a sliding strip which is provided with balls is arranged between the inner side wall of the outer rail and the outer side wall of the intermediate rail, the intermediate rail and the inner rail are nested through a ball groove which is provided with balls, a locking block is arranged on one side of the free end of the inner rail towards the intermediate rail, one side of the locking block is provided with a hook type buckle with elasticity, the locking block is fixed on the inner rail, the hook type buckle is extended out from one side of the inner rail, and the rolling friction is adopted between the outer rail and the intermediate rail and between the intermediate rail and the inner rail, thereby reducing the friction force among mechanisms. When the inner rail shrinks into the intermediate rail, the hook type buckle of the locking block can be clamped in the inner groove of the intermediate rail, thereby realizing the self-locking, and the inner rail is restored to freely slide in the intermediate rail after pulling the inner rail by forces until the hook type buckle separates from the inner groove of the intermediate rail. Therefore, the utility model can realize the self-locking of the inner rail through adopting the hook type buckle.
Description
Technical field:
The utility model relates to the railroad technical field, refers in particular to a kind of three-folding fastening-pulling type self-locking sliding-rail device.
Background technology:
Slide rail designs in order to realize relatively moving of two adjacent articles, and for example in the employed desk of people, mostly the folding of drawer is to realize by this railroad.Early stage railroad mainly comprises two draw runners that are separately positioned on desk and the drawer, the draw runner that wherein is arranged on the drawer will be along the draw runner slippage that is fixed on the desk, this railroad is owing to the force of sliding friction that must overcome when working between the draw runner, if the faying face between the draw runner is smooth inadequately, then coefficient of friction is bigger, thereby frictional force is bigger, causing drawer to move has some setbacks, and, can cause the draw runner wearing and tearing very fast because sliding friction is big, cause product to shorten service life.At above-mentioned situation, people are through improving design, roller devices for example is set between draw runner, this mode that replaces sliding friction by rolling friction, make the folding of drawer convenient and smooth and easy many really, but its stability of structure still is not fine, and bearing capacity is relatively poor, and this early stage slide rail is not provided with self-locking device, slide rail can be free to slide along track is two-way, when slide rail need be the certain slope placement, because the gravity effect, the object that is connected with slide rail can not remain on high-order transfixion, not reach the effect of stretching out the location.
The utility model content:
The purpose of this utility model is exactly to provide a kind of three-folding fastening-pulling type self-locking sliding-rail device at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is: three-folding fastening-pulling type self-locking sliding-rail device, it comprises outer rail, middle rail and interior rail that mutual superposition nests together, the draw runner that ball is installed is set between the lateral wall of outer rail madial wall and middle rail, in rail and interior rail by nested connection of pearl groove of ball is housed, the free end of interior rail is provided with latch segment towards a side of middle rail, one side of latch segment is provided with a rubber-like and colludes the shape buckle, on the rail, collude the shape buckle and stretch out in latch segment is fixed on by a side of interior rail.
Interior rail also is provided with a guide pad at an end that is fixed with latch segment.
Be provided with shockproof blob of viscose in the one end inside groove of described outer rail.
Described draw runner surface evenly offers through hole, is provided with ball in the through hole.
The strip groove that described pearl groove is an opening, the sidewall of groove evenly offers through hole, is provided with ball in the through hole.
After adopting said structure, between outer rail and the middle rail, be rolling friction between middle rail and the interior rail, can reduce between each mechanism frictional force, the free end of interior rail is provided with latch segment towards a side of middle rail, when interior rail shrink enter in during rail, latch segment collude the shape buckle snap in in the inside groove of rail, realize self-locking, enforce interior rail, the inside groove of rail in colluding the disengaging of shape buckle, interior rail recovers to be free to slide in middle rail, can realize interior rail self-locking so the shape buckle is colluded in the utility model employing.

The specific embodiment:
See shown in Fig. 1 to 8, the utility model comprises outer rail 1, middle rail 2 and interior rail 3, and these three parts mutual superposition nest together and form a kind of stretchable railroad, wherein outer rail 1 is used for linking to each other with other objects, middle rail 2 is as extension in this railroad, and by middle rail 2 outer rail 1 and interior rail 3 are coupled together, interior rail 3 is used for this railroad is fixed on object; The free end of interior rail 3 is provided with latch segment 4 towards a side of middle rail 2, and a side of latch segment 4 is provided with a rubber-like and colludes shape buckle 41, on the rail 3, colludes shape buckle 41 and is stretched out by a side of interior rail 3 in latch segment 4 is fixed on; When interior rail 3 shrink enter in during rail 2 are elastomers owing to collude shape buckle 41, collude shape buckle 41 can snap in in the inside groove of rail 2, realize self-locking, rail 3 in enforcing, up to collude shape buckle 41 break away from the inside groove of rail 2, interior rail 3 recovers to be free to slide in middle rail 2.
See shown in Fig. 1,9 that interior rail 3 also is provided with a guide pad 5 at an end that is fixed with latch segment 4, guide pad 5 can provide guide effect for the slip of interior rail 3.
See shown in Figure 1, be provided with shockproof blob of viscose 6 in the one end inside groove of described outer rail 1, when central rail 2 and interior rail 3 slide into this end of outer rail 1, rail 2 was from the effect of this end landing during shockproof blob of viscose 6 not only can play and prevent, can also play cushioning effect, make railroad can not produce noise in the course of the work.
See shown in Fig. 1,6,7 that the draw runner 8 that ball 7 is installed is set between the lateral wall of outer rail 1 madial wall and middle rail 2, and described draw runner 8 surfaces evenly offer through hole, are provided with ball 7 in the through hole; Middle rail 2 and pearl groove 9 nested are connected of interior rail 3 by ball 7 is housed, described pearl groove 9 is the strip groove of an opening, and the sidewall of groove evenly offers through hole, is provided with ball 7 in the through hole.
