Description
Technical field
The utility model is related to a kind of slide rail, and in particular to a kind of slide rail opened in order.
Background technology
The section rail of 8-shaped three of prior art does not have order mechanism, causes order of the slide rails at different levels in opening more chaotic.
For example, when opening slide rail, the interior rail in slide rail is often first drawn out, and is then that middle rail is drawn out again.Because slide rail is opened
When, its interior rail is in the distalmost end of slide rail, therefore the deformation of interior rail is also maximum, if so being interior rail every time prior to middle rail quilt
Pull out, then interior rail can have teetertottering by a relatively large margin when pulling out, and this can cause the motion of slide rail extremely unstable, can cause
Operation has some setbacks, situations such as slide rail failure easily occur, is unfavorable for normally using.
Utility model content
In order to overcome the problem of above-mentioned prior art is present, the utility model aims to provide a kind of cunning opened in order
Rail, strengthens the stability of slide rail.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：
A kind of slide rail opened in order, including outer rail, middle rail and interior rail, the middle rail pass through the activity of the first ball retainer
Ground is arranged in the track of the outer rail, and the interior rail is movably arranged as the track of the middle rail by the second ball retainer
In, an interior rail guide, section and the middle rail of the interior rail guide are provided with the track of the middle rail front end
Section is corresponding, and the interior rail guide is fitted completely with the inwall of the middle rail, the left and right sides point of the interior rail guide
It is not provided with an inwardly projecting projection, the outer wall of the projection of the left and right sides respectively with the interior rail left and right sides connects
Touch；At least side is provided with convex closure on the outer wall of the anterior left and right sides of the interior rail, when the interior rail be all placed in it is described in
When in the track of rail, the convex closure is located at the rear of the projection of the interior rail guide, when the interior rail is from the rail of the middle rail
When being stretched out in road, of short duration interference fit can occur with the projection of the interior rail guide for the convex closure, and the interior rail is through described
Interior rail guide stretches out the middle rail.
Further, it is respectively arranged with a convex closure on the outer wall of the anterior left and right sides of the interior rail.
Operation principle of the present utility model is：
When slide rail needs to open, because the convex closure on interior rail outer wall act as the effect of block so that convex closure and interior rail
Friction between guide increases, therefore the relatively small middle rail of friction can be taken the lead in pulling out from outer rail, and interior rail then can be temporary
When rest in middle rail；After central rail is completely pulled out of, it need to only increase the pulling force of a little and just may be such that convex closure is oriented to interior rail
Of short duration interference fit occurs between part, just can will be pulled out in interior rail therefrom rail, finally realize the opening in order of three section rails.
The beneficial effects of the utility model are:
Of the present utility model simple in construction, manufacturing cost is low, is easy to promote and uses.In its interior rail guide can be given
Rail certain supporting role, it is possible to reduce interior rail is rocked so that more stablize on slide rail motion ground.And convex closure and interior rail guide
Use cooperatively, then can realize the opening in order of three section rails, such benefit is just so that slide rail is more suitable in operation
Freely, it is to avoid because interior rail be first drawn out it is rear and caused by problem on deformation, also improve the service life of slide rail.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.Embodiment of the present utility model is shown in detail by following examples and its accompanying drawing.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding to of the present utility model, constitutes the part of the application,
Schematic description and description of the present utility model is used to explain the utility model, does not constitute to of the present utility model improper
Limit.In the accompanying drawings：
Fig. 1 is sectional view of the present utility model；
Fig. 2 is installation diagram of the present utility model；
Structural representation when Fig. 3 stretches out for interior rail of the present utility model.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
Shown in reference picture 1-3, a kind of slide rail opened in order, including outer rail 1, middle rail 2 and interior rail 3, the middle rail 2 leads to
The first ball retainer 4 is crossed to be movably arranged as in the track of the outer rail 1, the interior rail 3 by the second ball retainer 5 actively
In the track for being arranged on the middle rail 2, an interior rail guide 6 is provided with the track of the middle front end of rail 2, the interior rail is led
Corresponding with the section of the middle rail 2 to the section of part 6, the interior rail guide 6 is fitted completely with the inwall of the middle rail 2,
The left and right sides of the interior rail guide 6 is respectively arranged with an inwardly projecting projection, the projection difference of the left and right sides
With the wall contacts of the interior left and right sides of rail 3；On the outer wall of the anterior left and right sides of the interior rail 3 at least side be provided with it is convex
Bag 7, when the interior rail 3 is all placed in the track of the middle rail 2, the convex closure 7 is located at the projection of the interior rail guide 6
Rear, when being stretched out in track of the interior rail 3 from the middle rail 2, the convex closure 7 can be convex with the interior rail guide 6
Of short duration interference fit occurs for block, and the interior rail 3 stretches out the middle rail 2 through the interior rail guide 6.
Further, it is respectively arranged with a convex closure 7 on the outer wall of the anterior left and right sides of the interior rail 3.
Operation principle of the present utility model is：
When slide rail needs to open, because the convex closure on interior rail outer wall act as the effect of block so that convex closure and interior rail
Friction between guide increases, therefore the relatively small middle rail of friction can be taken the lead in pulling out from outer rail, and interior rail then can be temporary
When rest in middle rail；After central rail is completely pulled out of, it need to only increase the pulling force of a little and just may be such that convex closure is oriented to interior rail
Of short duration interference fit occurs between part, just can will be pulled out in interior rail therefrom rail, finally realize the opening in order of three section rails.
Interior rail guide can give interior rail certain supporting role, it is possible to reduce interior rail is rocked so that slide rail is moved
More stablize on ground.And using cooperatively for convex closure and interior rail guide, then the opening in order of three section rails can be realized, it is such good
Place is just so that slide rail is more smooth in operation, it is to avoid because interior rail be first drawn out it is rear and caused by problem on deformation, also improve
The service life of slide rail.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
