Description

滑軌開啟的順序拉出結構 Sliding rail open sequence pull-out structure

本發明係指一種滑軌開啟的順序拉出結構,涉及一種滑軌開啟時依順序先由內軌連同中軌同時向前滑移然後再由內軌向前滑移的順序拉出結構之相關技術領域。 The present invention relates to a sequential pull-out structure for opening a slide rail, relating to a sequential pull-out structure in which the slide rail is firstly slipped forward by the inner rail together with the middle rail and then slipped forward by the inner rail. Technical field.

按,常見的三段式滑軌進行開啟動作時係由內軌先行拉出再帶動中軌,或是內軌、中軌同時一併拉出,並無法控制內軌及中軌的滑動順序,例如以內軌與抽屜結合固定為例,當抽屜連同內軌拉出之後左、右兩邊的滑軌向外打開的長度雖然相同,但是左、右兩邊滑軌內的內軌與中軌的滑動順序及相對拉開行程未必一致,使得左右兩邊的滑軌中各自的外軌、中軌與內軌所承受的應力不相同,導致在長期使用下,左、右兩邊的滑軌容易因產生不同磨耗,使得滑軌的滑動順暢性、穩定性降低或單獨一邊的滑軌損壞,進而降低使用壽命,而先前的技術例如台灣新型第M411165號以及M420244號「側走式滑軌之抽拉同步裝置及其滑軌單元」專利案雖揭露了滑軌開啟打開時的順序拉出相關技術,但由於其結構複雜、構件多、組裝不易、成本高,且若不潤滑容易產生噪音。 According to the common three-stage slide rail, the inner rail is pulled out first and then the middle rail is pulled forward, or the inner rail and the middle rail are pulled out at the same time, and the sliding order of the inner rail and the middle rail cannot be controlled. For example, the inner rail and the drawer are fixed together. For example, when the drawer is pulled out together with the inner rail, the lengths of the slide rails on the left and right sides are the same, but the sliding sequence of the inner rail and the middle rail in the left and right slide rails is the same. The relative pulling strokes are not necessarily the same, so that the stresses on the outer rails, the middle rails and the inner rails of the left and right sliding rails are different, which results in different wear on the left and right sides of the rails under long-term use. The slide rails are smoothed, the stability is reduced, or the slide rails on the single side are damaged, thereby reducing the service life, and the prior art, such as Taiwan's new type M411165 and M420244 "side walk type slide rail pull synchronization device and The patent system of the slide rail unit discloses the sequential pull-out technology when the slide rail is opened and opened, but the structure is complicated, the components are large, the assembly is not easy, the cost is high, and if it is not lubricated, noise is easily generated.

本發明者乃有鑑於此,經過不斷的研究、改良與測試,乃發明設計一種滑軌開啟的順序拉出結構。 In view of this, the present inventors have invented and designed a sequential pull-out structure for sliding rails through continuous research, improvement and testing.

本發明的主要目的在於提供一種滑軌開啟的順序拉出結構,係透過分別設於內軌與中軌的控制件以及 固定件的兩個簡單構件,即可使滑軌欲開啟時順序先由內軌連同中軌同時向前滑移,再由內軌向前(外)滑移而完成開啟動作,進而可提昇滑軌開啟動作的順暢性與穩定性。 The main object of the present invention is to provide a sequential pull-out structure for sliding rails, which is transmitted through control members respectively disposed on the inner rail and the middle rail, and The two simple components of the fixing member can make the sliding rails slide forward from the inner rail together with the middle rail at the same time, and then the inner rail slides forward (outer) to complete the opening movement, thereby improving the sliding. Smoothness and stability of the rail opening action.

本發明的次一目的在於提供一種滑軌開啟的順序拉出結構,可避免滑軌欲開啟時內軌單獨先被向前拉出,使內軌因負載過重而容易導致相關部位變形損壞,或避免導致滑軌開啟時的向前拉出動作不順暢、不穩定的情形產生,並相對可提高使用壽命。 A second object of the present invention is to provide a sequential pull-out structure for opening a slide rail, which can prevent the inner rail from being pulled forward first when the slide rail is to be opened, so that the inner rail is easily damaged due to excessive load, or Avoid the situation that the forward pull-out action when the slide rail is opened is not smooth and unstable, and the service life can be relatively increased.

Through the two simple components of the control member 6 and the fixing member 7 respectively disposed on the inner rail 1 and the middle rail 3, the slide rail can be sequentially moved forward by the inner rail 1 together with the middle rail 3 in order to be opened. Then, the inner rail 1 slides forward (outer) to complete the opening action, thereby improving the smoothness and stability of the slide rail opening action.

2.可避免滑軌欲開啟時內軌1單獨先被向前拉出,使內軌1因負載過重而容易導致相關部位變形損壞,或避免導致滑軌開啟時的向前拉出動作不順暢、不穩定的情形產生,並相對可提高使用壽命。 2. It can be avoided that the inner rail 1 is first pulled forward when the slide rail is to be opened, so that the inner rail 1 is easily damaged due to excessive load, or the forward pull-out action when the slide rail is opened is not smooth. An unstable situation arises and can increase the service life.
