Abstract
The utility model relates to a slide rail device technical field, in particular to a two-fold self-locking slide rail. The utility model comprises an outer rail and an inner rail which are overlapped and nested together. A stopping mechanism for preventing the inner rail from falling off is arranged on the outer rail, and the outer rail and the inner railed are nested together through a ball groove with balls. An inner groove on one end of the inner rail is provided with a self-locking mechanism which comprises a self-locking piece, a draught spring and a slider, wherein the self-locking piece fixed in the inner groove on one end of the inner rail is provided with an L-shaped chute where the slider is placed, projecting posts are respectively arranged on the surfaces of two ends of the slider, one end of the draught spring is fixed on the self-locking piece, and the other end of the draught spring is connected with one end of the slider. A stopper is arranged on the inner bottom of the outer rail; as the inner groove on one end of the inner rail is provided with the self-locking mechanism, one end of the inner rail can be locked in the self-locking mechanism; the inner rail can break away from the self-locking mechanism when being pushed forcibly, thereby bringing about convenience and practicability.
Description
Technical field:
The utility model relates to the railroad technical field, refers in particular to a kind of two folding self-locking sliding-rails.
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 object 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 two folding self-locking sliding-rails at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is: it comprises outer rail and interior rail that mutual superposition nests together, on outer rail, be provided with the position limiting structure that rail comes off in preventing, outer rail and interior rail are by being equipped with nested connection of pearl groove of ball, be provided with self-locking device in the inside groove of interior rail one end, self-locking device comprises self-locking block, tension spring and slide block, self-locking block is fixed in the inside groove of interior rail one end, self-locking block offers " L " shape chute, slide block is placed in the chute, and the surface at slide block two ends is respectively equipped with projection, and tension spring one end is fixed on the self-locking block, the other end is connected with slide block one end, and the outer rail inner bottom part is provided with block.
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, and the outer rail that contacts with ball and the side of interior rail form the guide groove of concavity respectively.
Described position limiting structure is the protruding grain that is located at outer rail two ends medial surface.
After adopting said structure, between outer rail and the interior rail is rolling friction, can reduce between each mechanism frictional force, in addition, in the inside groove of interior rail one end, be provided with self-locking device, interior rail one end can be locked in the self-locking device, and rail broke away from self-locking device in rail can make in enforcing, and is convenient and practical.

The specific embodiment:
See shown in Fig. 1 to 7, the utility model comprises outer rail 1 and interior rail 2, outer rail 1 and interior rail 2 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, interior rail 2 is used for this railroad is fixed on object, be provided with self-locking device 4 in the inside groove of interior rail 2 one ends, self-locking device 4 comprises self-locking block 41, tension spring 42 and slide block 43, self-locking block 41 is fixed in the inside groove of interior rail 2 one ends, self-locking block 41 offers " L " shape chute 411, slide block 43 is placed in the chute 411, the surface at slide block 43 two ends is respectively equipped with projection 431,432, tension spring 42 1 ends are fixed on the self-locking block 41, and the other end is connected with slide block 43 1 ends, and outer rail 1 inner bottom part is provided with block 5.
Described pearl groove 6 is the strip groove of an opening, and the sidewall of groove evenly offers through hole 61, is provided with ball 7 in the through hole 61, and the outer rail 1 that contacts with ball 7 and the side of interior rail 2 form the guide groove of concavity respectively.
Described position limiting structure is the protruding grain 8 that is located at outer rail 1 two ends medial surface, this protruding grain 8 can limit pearl groove 6 can not break away from fully outer rail 1 two ends.
Operation principle: when interior rail 2 stretched out, the slide block 43 of self-locking device 4 was in the end of chute 411, and the projection 431 of slide block 43 ends snaps in colluding in the groove of chute 411, and at this moment, tension spring 42 is in extended state; At interior rail 2 in outer rail 1 in the push-on process, being located at outer rail 1 inner bottom part is provided with block 5 and at first runs into projection 432, at this moment, groove is colluded in projection 431 disengagings, slide block 43 is returned to the chute end under the effect of tension spring 42, wherein, block 5 is between the projection 431 and projection 432 of slide block 43, and rail 2 is in the lock state in this moment; During rail 2, as long as rail 2 in enforcing, slide block 43 and block 5 produce relative motions, make the projection 431 of slide block 43 snap in colluding in the groove of chute 411 again in need releasing.
Certainly, the example of the above, it is preferred embodiments of the present utility model, be not to be used for limiting practical range of the present utility model, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
