Description

The thinning ball slide rail of second direction thickness

Technical field

This utility model system is related to a kind of ball slide rail, particularly relates to a kind of for the display with elevating function（Bag Include plate, monitor, liquid crystal display, similarly hereinafter）Lift in lifting support frame that module is relied on respect to column up-down to be used Ball slide rail.

Background technology

As ball sliding rail has rolling frictional resistance little, action is smooth, between stabilized structure, mutual movement parts it is several continuously Gap and the advantages of make motion rigidity high, be widely used the phase lifted in display lifting type bracing frame between module and column To on slip guiding structural.In recent years, it is with the progress and the change of people's aesthetic taste of the design of electronic product mechanism, more next More multi-display bracing frame pursuit column therein has slender outward appearance, and the more slender outward appearance of column is realized, which is crucial It is that the two slide rail overall dimensions installed in column from terms of transverse section are little, should specifically requires that the cross-section facial contour of slide rail is vertical at two Size on direction all need it is less at present, size is smaller on a direction wherein for slide rail, but other direction is outer Shape size is also bigger than normal.

At present, following (this of prior art construction closest with this utility model in display lifting support frame column Description, is please noted that, similarly hereinafter using title commonly used in the art to the Common parts in slide rail and construction)：

Refer to shown in Fig. 1 and Fig. 2, its specific configuration includes, from terms of transverse section, a substantially u-shaped outer rail 1a, one The U-shaped opening portion of substantially u-shaped interior rail 2a, the interior rail 2a towards and stretch into the U-shaped opening of the outer rail 1a It is interior；The two row ball 3a that separation is respectively arranged between the interior rail 2a and the outer rail 1a in interior two lateral surface of rail 2a （Each column ball includes several balls, and ball 3a is not illustrated in Fig. 1）, and from terms of transverse section, corresponding one is arranged on outer rail 1a And interior rail 2a between, the substantially ushaped pearl frame 4a for accommodating, being spaced two row ball 3a；Obviously, the outer rail 1a is such as from vertical A longitudinal conducting space is defined to seeing due to U-shaped, is available for rail 2a in described in U-shaped to be placed in wherein, the outer rail 1a With the interior rail 2a contacting with ball 3a, be provided with corresponding ball 3a guidings and carry along longitudinal direction on the wall supported and use Raceway, it is clear that have four raceways per one slide rail, be collectively forming two ball 3a roll channels respectively, this causes interior rail 2a It is mutually shifted by way of several ball 3a are along rolling path rolling and between outer rail 1a, with interior rail 2a and outer rail 1a phases needed for producing The effect of drag reduction when moving between mutually, and therefore also realize that both closely support indirectly simultaneously（By ball 3a）And it is real Existing gapless（Only lifting direction has degree of freedom）OQ t movement, and this also means that the display being attached thereto is being led When drawing lifting because the part gapless that is mutually shifted without produce the defect such as rock affect to use.

Two relative sections of its certainly pearl frame 4a u-shaped from terms of transverse section here split shed（U is removed equivalent to hypothesis Remaining part after the back cover section of font bottom, namely only retain the II font sections of U-shaped both sides）Be respectively used to accommodate and Every the two row ball 3a, this two sections of parts in U-shaped we be also referred to as（It is this utility model for ease of describing and understanding And especially call, prior art is U-shaped, there is no released state）Space bar 41a, each space bar of two space bar 41a 41a is designed with receiving portion 411a of the correspondence each column ball quantity along longitudinal direction（Typically one incomplete circular hole）, to Each ball 3a of each column separately and is accommodated and is maintained in receiving portion 411a, in order to avoid mutually wipe and touch when rolling between ball 3a Interfere（Transport assembling is also allowed for simultaneously）；Outer rail 1a and interior rail 2a respectively with display bracket base on column with lift Mobile lifting module is mutually connected, and finally makes the lifting module of display bracket can be along ball 3a slide rail guide path phases Column is done without the reciprocating linear displacement for rocking gap.

But also just as it was previously stated, pearl frame 4a its major part in the ball slide rail of prior art is approximately from terms of transverse section Ringent U-shaped construction, i.e. by one lateral edges of respective longitudinal direction of two space bar 41a（In the U-shaped opening of neighbouring outer rail 1a It is interior most in lateral edges at inwall）Mutually extend bending to link into an integrated entity part（I.e. from terms of transverse section, equivalent to by II shapes one Body back cover becomes U-shaped）, its objective is to make that two space bar 41a are hanging, separate, be integrally formed, particularly also for being easy to At back cover, backstop is set；It is so-called to set backstop, refer to pearl frame 4a interior rail 2a lifting movings must the upper end in pathway footpath do one and stop Gear structure（The stop configurations are not illustrated in Fig. 1, Fig. 2）, enable and the interior rail 2a of ascending motion can collide and be forced by interior rail 2a Drive, during for preventing pearl frame 4a without backstop, in outer rail 1a after reciprocal lifting repeatedly, pearl frame 4a adds interior rail 2a because of gravity Upper ball 3a has asynchronous unavoidably and pearl frame 4a is not integrally gradually caught up with interior rail 2a and is constantly dropped downwards in rolling, cause same When the reduction of the ball 3a quantity of effective work supported, i.e. both multiple relatively described interior rails of the pearl frame 4a after relative movements The degree of overlapping of 2a can be gradually decreased, it is clear that conflict is at this moment simultaneously participated in interior rail 2a, outer rail 1a ball channels, work is rolled The ball 3a total quantitys accordingly will be reduced, and this certainly will just affect the motion rigidity of slide rail, display to be possible to unstable, shake It is dynamic；And set can have an opportunity when stop configurations then can rise to high point by interior rail 2a every time touch at the backstop of a pearl frame 4a and Force drive ball 4a to keep in the center again put, down gradually do not drop（Stop configurations position is longitudinally seen from pearl frame 4a and is generally set The close upper end put, specifically to prior art, such as longitudinally sees the shapes such as top local stamped bumps in the back cover part Into）.

But therefore the pearl frame 4a of prior art also will be limited by the structural factor of back cover section in this U-shaped, cause slide rail on edge The U-shaped opening direction of outer rail 1（It is referred to as in the industry second thickness direction or second direction）Thickness is partially thick, this is because, the bending The sheet steel sections itself of the back cover section of connection just have thickness（Because needing some strength）, it is particularly also same plus the back cover section When be two second directions for avoiding grazing outer rail 1a and interior rail 2a from having to stay gap, therefore which must take one Fixed slide rail second direction thickness, it is still thicker in the thickness that this side up that this allows for whole ball 3a slide rails, so as to limit Its application in column has the display lifting support frame of more slender requirement is made（It is difficult to install under receiving）, or in other words Say, it is lower in identical form factor lower pillar stand rigidity and intensity（Because column it is slender when, column ratio of rigidity is relatively low, column be eager to excel Degree or rigidity higher position need to be metal filled by there is more spaces to carry out, therefore if the outward appearance of slide rail is big in all directions size, with regard to nothing Method is vacateed more spaces and enriches metal to improve rigidity and intensity to column body）.

Therefore, generally speaking, prior art ball slide rail is still partially thick in the thickness of second direction, more slender in appearance requirement When changing column outward appearance during the column of type or not and requiring column strength and higher rigidity, its purposes is still very limited, nothing Method is perfectly suitable for the display lifting support frame product of the slender structure of such appearance requirement column.Therefore ball slide rail how mat The improvement reduced in second direction thickness by existing structure, enabling existing ball slide rail to be employed for more kinds of columns has more In the display bracket of slender requirement, that is, expand its use range, it has also become one of be intended to important topic for solving of the industry.
