Abstract

The utility model relates to an adjustable ball slideway which is composed of an outer framework, a middle framework, an inner framework, balls, a ball retaining rack. The utility model is structurally improved in that elastic tongue pieces are shaped on the inner framework and the outer framework which are provided with trim mechanisms at positions corresponding to the elastic tongue pieces. The utility model structured in the way overcomes the defect of a traditional mode that a shim is inserted by hands for adjusting an installing gap of a framework, and has the advantages of easy adjustment of installing gaps for the slideway, high installation accuracy, high reliability, etc.

Description

The adjustable ball slide rail

The utility model relates to the ball slide rail that the technical field of rail plate, particularly drawer are used.

At present, the ball slide rail used of common drawer usually by interior, in, outer three layers of C type skeleton, ball and ball retainer constitute.During installation inner framework be fixed on the drawer, outer skeletal fixation on the sidewall in drawer chamber, by ball and middle level skeleton make drawer can be in the drawer chamber telescopic slide.But in the actual installation process, owing to have scale error between drawer and the drawer chamber, both are not absolute parallel, often need to adjust the installing space of internal layer, outer skeleton, and traditional way is to plug pad in the installation site of skeleton, will adjust repeatedly, insert the polylith pad sometimes and just realize installing parallel.Obviously, it is very difficult, complicated that the back cushion sheet is adjusted the slide rail installing space, and installation accuracy is not high, reliability is low, has seriously influenced installation effectiveness and product quality.

The purpose of this utility model is the weak point that overcomes above-mentioned prior art, provide a kind of adjust simple easily, the adjustable ball slide rail of high, the good reliability of installation accuracy.

The purpose of this utility model is achieved by the following technical solution: the adjustable ball slide rail, include outer skeleton, middle level skeleton, inner framework, ball, ball retainer etc., special feature is to form elastic tongue piece on inner framework or the outer skeleton, and the position of corresponding tongue piece is equipped with the micro-adjusting mechanism that can change the tongue piece subtended angle on the skeleton.Further, micro-adjusting mechanism is made of the backing plate and the double-screw bolt of band screw.

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the rearview of Fig. 1;

Fig. 4 is the front view of embodiment two;

Fig. 5 is the vertical view of Fig. 4;

Fig. 6 is the rearview of Fig. 4.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are further elaborated.

Embodiment one:

Referring to Fig. 1-Fig. 3, basic composition is of present embodiment: be loaded on outermost outer skeleton 1, be loaded on the inner framework 2 of innermost layer, the middle level skeleton 3 that is loaded between outer skeleton 1, the inner framework 2 and can slides relatively is loaded between outer skeleton 1 and the middle level skeleton 3 and is loaded on ball 4 and retainer thereof between inner framework 2 and the middle level skeleton 3.During installation, inner framework 2 is fixed on the drawer, 1 on outer skeleton is fixed on the sidewall in drawer chamber, for ease of adjusting the assemblage gap of outer skeleton 1, improvements are that punch forming has a plurality of elastic tongue pieces 5 on the outer skeleton 1, the screw thread micro-adjusting mechanism that is made of double-screw bolt 6 and backing plate 7 is housed on each elastic tongue piece 5, have screw on the backing plate 7, double-screw bolt 6 cooperates with screw.Under the general state, double-screw bolt 6 only slightly contacts with elastic tongue piece 5, elastic tongue piece 5 keeps same horizontal level with outer skeleton 1, in the time will adjusting the assemblage gap of outer skeleton 1, double-screw bolt 6 need only be screwed in, elastic tongue piece 5 is subjected to double-screw bolt 6 precompressed and outwards perk, produce certain subtended angle, double-screw bolt 6 screws in dark more, and elastic tongue piece 5 perks are high more, and subtended angle is big more.Like this, as long as change the screw-in depth of double-screw bolt 6, just can control elastic tongue piece 5 outside open degree, thereby adjust the assemblage gap of outer skeleton 1, the monolateral gap adjustment amount of present embodiment is 3 millimeters.

Embodiment two:

Referring to Fig. 4-Fig. 6, the basic structure of present embodiment is identical with embodiment one, be outer skeleton 1 ' and inner framework 2 ' on all form elastic tongue piece 5 ' and micro-adjusting mechanism, micro-adjusting mechanism is equally by double-screw bolt 6 ' and the backing plate 7 of band screw ' constitute.Such structure, make outer skeleton 1 ' and inner framework 2 ' assemblage gap all can pass through double-screw bolt 6 ' adjustment, realize two-way adjustment, adjustment amount reaches 6 millimeters.

In sum, the utlity model has obvious superiority:

1, the adjusting device of double-screw bolt, backing plate, elastic tongue piece composition has been simplified the peace of drawer greatly Dress, adjustment programme use simple, convenient;

2, micro-adjusting mechanism is succinct, compact, and the adjusting play scope is big, and regulation and control easily;

3, improved the installation accuracy of slide rail, push-and-pull is more smooth suitable;

4, reliability height, long service life has guaranteed the quality of product.

Claims

1, adjustable ball slide rail, include outer skeleton, middle level skeleton, inner framework, ball, ball retainer etc., it is characterized in that: form elastic tongue piece on inner framework or the outer skeleton, the position of corresponding tongue piece is equipped with the micro-adjusting mechanism that can change the tongue piece subtended angle on the skeleton.

2, slide rail according to claim 1 is characterized in that micro-adjusting mechanism is made of the backing plate and the double-screw bolt of band screw.

3, slide rail according to claim 1 and 2 is characterized in that all forming elastic tongue piece and micro-adjusting mechanism on inner framework and the outer skeleton.
