Description

The removable slide rail of three foldings

Technical field:

The utility model relates to the railroad technical field, refers in particular to the removable slide rail of a kind of three foldings.

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 the outer rail that is arranged on the desk and is arranged on interior rail on the drawer, and outer rail and interior rail are by draw runner or chute is nested is connected, and the interior rail that wherein is arranged on the drawer will be along the outer rail slippage that is fixed on the desk, the folding of realization drawer.But the inside and outside rail of this railroad is relatively-stationary, and interior rail can not break away from from outer rail, and promptly drawer cannot be dismantled, and brings puzzlement for the cleaning of drawer.

The utility model content:

The utility model is exactly to provide a kind of three foldings removable slide rail at the deficiency of prior art existence, and rail can separate the affixed drawer of rail convenient for cleaning and interior with middle rail in it.

To achieve these goals, the technical solution adopted in the utility model is: it comprises the outer rail that mutual superposition nests together, middle rail and interior rail, at outer rail, in be respectively arranged with on rail and the interior rail and prevent the position limiting structure that comes off mutually, 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 one side relative with middle rail at interior rail is fixed with a fastener, fastener also is combined with a handle, this fastener openend is provided with two elastic strips, elastic strip simultaneously offers chute, the end surfaces of shaking hands is symmetrically arranged with the raised line that cooperates with chute, end at the corresponding fastener of middle rail is fixed with fixed block, the surface of the relative fastener of fixed block has chute, and this chute cooperates with fastener, and the width of the width of chute when opening less than fastener two elastic strips.

Described draw runner surface evenly offers through hole, is provided with ball in the through hole, and the outer rail that contacts with ball and the side of middle rail form the guide groove of inner concavity respectively.

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 middle rail that contacts with ball and the side of interior rail form the guide groove of concavity respectively.

After adopting said structure, interior rail can separate with middle rail, and promptly affixed with interior rail object (for example drawer) can separate with middle rail, makes things convenient for the cleaning of object like this.

The specific embodiment:

See shown in Fig. 1 to 6, 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 outer rail 1 and interior rail 3 are coupled together by middle rail 2, interior rail 3 is used for this railroad is fixed on object, inner bottom surface at interior rail 3 is fixed with a fastener 11, fastener 11 also is combined with a handle 12, these fastener 11 openends are provided with two elastic strips 111, elastic strip 111 one sides offer chute 13,12 1 end surfaces of shaking hands are symmetrically arranged with the raised line 14 that cooperates with chute 13, end at middle rail 2 corresponding fasteners 11 is fixed with fixed block 15, the surface of fixed block 15 relative fasteners 11 has chute 151, and this chute 151 cooperates with fastener 11, and the width of the width of chute 151 when opening less than 11 liang of elastic strips 111 of fastener.

Middle rail 2 two ends are stopped by position limiting structure, this position limiting structure is postive stop baffle 16 and the bipod limited block 17 that is arranged on outer rail 1 two ends, postive stop baffle 16 also is socketed with damping gum cover 18, when central rail 2 slides in the inside groove of outer rail 1 together with draw runner 9, draw runner 9 can be stopped by bipod limited block 17, make draw runner 9 and the middle rail 2 can be from this end landing, central rail 2 can stop that middle rail 2 can be from this end landing yet by limited baffle plate 16 when the other end slides; The bipod limited block 23 of rail 2 one ends during position limiting structure on the middle rail 2 is specially and is arranged on, the pearl groove 10 that slides in middle rail 2 is stopped that by bipod limited block 23 rail 3 can be from this end landing in making; External part at interior rail 3 is spacing by fixed block 15, and at this moment, two elastic strips 111 of fastener 11 are in open configuration, two elastic strips 111 piece 15 that is fixed stops, rail 3 can not separate with middle rail 2 in making, and with pulling moving handle 12, the raised line 14 of handle 12 slides along the chute 13 of elastic strip 111, the opening angle of two elastic strips 111 is diminished, at this moment, elastic strip 111 can enter in the chute 151 of fixed block 15, continues rail 3 in the pulling, interior rail 3 can separate with middle rail 2, and rail 3 is detachable in making.

The draw runner 9 that ball 8 is installed is set between the lateral wall of outer rail 1 madial wall and middle rail 2, described draw runner 9 surfaces evenly offer through hole, be provided with ball 8 in the through hole, the outer rail 1 that contacts with ball 8 and the side of middle rail 2 form the guide groove 101,201 of inner concavity respectively; Middle rail 2 and pearl groove 10 nested are connected of interior rail 3 by ball 8 is housed, described pearl groove 10 is the strip groove of an opening, the sidewall of groove evenly offers through hole, is provided with ball 8 in the through hole, and the middle rail 2 that contacts with ball 8 and the side of interior rail 3 form the guide groove 202,301 of concavity respectively.

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.
