Abstract
The utility model discloses a self-closed buffer of a drawer slide, which comprises a fixed base, a movable base, drawing springs, a damper, a guiding groove and a bent arm, wherein the movable base is slidably connected to one end of the fixed base, the drawing springs and the damper are connected with the fixed base and the movable base, the guiding groove with a corner is disposed on the fixed base, and the bent arm installed on the movable base in sliding fit with the guiding groove and realizes self-locking function. The drawing springs are positioned on two sides of the fixed base and the movable base in a balanced mode respectively, the damper is arranged in the middles of the fixed base and the movable base, a sliding rail extends from one end of the fixed base slidably connected with the movable base, the guiding groove is mounted on the sliding rail, and an installing base which is disposed on the movable base and used for installing the bent arm is slidably connected with the sliding rail. Due to two groups of the drawing springs and the double-section sliding rail, the problem that the service life is affected caused by abrasion resulting from unbalanced force and suspending swing of the self-closed buffer movable base is radically resolved.
Description
Technical field
The utility model relates to the drawer sliding rail technical field, relates in particular to the buffering self-closing device of drawer sliding rail.
Background technology
The buffering self-closing device of existing drawer sliding rail is that the side in holder and sliding seat is connected and installed extension spring, and opposite side then is connected and installed damper.Since both sides be subjected to force unbalance, and cause sliding seat to tend to install a side of extension spring, make that the friction between holder and the sliding seat strengthens, cause wearing and tearing easily and have influence on service life of buffering self-closing device.Also have because holder and sliding seat are to adopt single slide rail to be slidingly connected, that is to say and only adopt one section slide rail to realize being connected between holder and the sliding seat, sliding seat is to be supported by this slide rail fully.When sliding seat slipped away holder, the part that both contact on slide rail can be fewer and feweri, up to minimum.At this moment, holder also can become minimum to the supporting dynamics of sliding seat, the relative fixed seat, and the sliding seat major part is unsettled, this is easy to cause the sliding seat swing, understands enhance faster wear equally and has influence on service life of buffer.
The utility model content
Technical problem to be solved in the utility model provides a kind of rational in infrastructure, stress balance, durable drawer sliding rail buffering self-closing device.
The technical problems to be solved in the utility model is to realize by following technical scheme: a kind of buffering self-closing device of drawer sliding rail, comprise a holder, the sliding seat that is slidingly connected with an end of described holder, the extension spring and the damper that connect described holder and sliding seat, be opened in the gathering sill that is formed with the turning on the described holder, and be installed on the described sliding seat be slidingly matched with described gathering sill and realize self-locking crank arm, it is characterized in that: described extension spring balance respectively is arranged at the both sides of described holder and sliding seat, described damper then is arranged at the middle part of described holder and sliding seat, described holder extends a slide rail again in the end of an end that is slidingly connected with described sliding seat, described gathering sill is opened on the described slide rail, is located to be used on the described sliding seat that described mount pad of cranking arm is installed and described slide rail is slidingly connected.
Adopt the beneficial effect that the utility model brought: owing to adopt two groups of extension springs to be connected to the both sides of holder and sliding seat, and damper just is arranged at both middle parts, and having solved buffering self-closing device sliding seat influences the problem in service life because of being subjected to force unbalance to cause wearing and tearing.Also have owing to adopted two sections slide rails to realize being slidingly connected between holder and the sliding seat, on existing basis, set up in the slide rail of holder end extension and the mount pad of cranking arm on the sliding seat and be slidingly connected, the holder even if sliding seat slips away, the two ends of sliding seat are bearing on the whole holder all the time, and fundamentally having solved buffering self-closing device sliding seat influences the problem in service life owing to unsettled swing causes wearing and tearing.

The specific embodiment
Shown in Fig. 1-4, a kind of buffering self-closing device of drawer sliding rail, sliding seat 2, the extension spring 3 and the damper 4 that are connected and fixed seat 1 and sliding seat 2 that comprises a holder 1, is slidingly connected with an end of holder 1, be opened in the gathering sill 101 that is formed with the turning on the holder 1 and be installed on the sliding seat 2 with gathering sill 101 be slidingly matched realize self-locking crank arm 5.Extension spring 3 balance respectively is arranged at the both sides of holder 1 and sliding seat 2, damper 4 then is arranged at the middle part of holder 1 and sliding seat 2, holder 1 extends a slide rail 102 again in the end of an end that is slidingly connected with sliding seat 2, gathering sill 101 is opened on the slide rail 102, is located to be used to install 5 the mount pad 201 of cranking arm on the sliding seat 2 and to be slidingly connected with slide rail 102.
When pulling out drawer, the movable rail of drawer sliding rail is held the hook arm 501 of cranking arm on 5, drawing sliding seat 2 holder 1 that slips away outward, slip into the turning of gathering sill 101 ends to form self-locking up to the slide block 502 of cranking arm on 5, this moment, the movable rail of drawer sliding rail will break off relations with the hook arm 501 of cranking arm on 5, the movable rail of drawer sliding rail breaks away from the buffering self-closing device like this, along with drawer slides outward.
When promoting drawer inward, the movable rail of the drawer sliding rail push arm 503 on 5 that promotes to crank arm, at first make the slip away turning of gathering sill 101 of slide block 502, sliding seat 2 is slowly slided under the effect of extension spring 3 and damper 4 inwards, hook arm 501 can draw drawer by pulling activity rail simultaneously, close fully up to drawer, the buffering that finally realizes drawer is from closing.
