Abstract
A synchronous mechanism of a slide rail includes a first hooked bracket, a second hooked bracket, an inner hook set and an outer hook set. The first hooked bracket and the second hooked bracket are installed on a middle rail, and the inner hook set is installed on an inner rail, and the outer hook set is installed on an outer rail. When the slide rail is pulled out or pushed in, the inner, middle, and outer rails are interacted, so that the inner rail, the middle rail and the outer rail can be moved synchronously when they are pushed in or pulled out, so as to improve the smoothness and stability of the operation and the practicality and service life of the product.
Claims4
A synchronous mechanism of a slide rail, and the slide rail including an inner rail, a middle rail and an outer rail, and the synchronous mechanism driving the inner rail, the middle rail and the outer rail to be sequentially pulled out or pushed in, and a direction of pulling out the rail being defined as a front side, and the synchronous mechanism comprising:
- a first hooked bracket, movably and pivotally coupled to a surface of the middle rail, and having a first elastic portion and a first stop portion disposed on two opposite sides of the first hooked bracket respectively, and a first lever installed to a side of the first stop portion;
- a second hooked bracket, movably and pivotally coupled to a surface of the middle rail, and disposed with a spacing apart from a side of the first hooked bracket, and having a second elastic portion and a second stop portion disposed on two opposite sides of the second hooked bracket respectively, and a second lever installed to a side of the second stop portion;
- an inner hook set, installed in a middle section of the inner rail, and disposed on a surface configured to be corresponsive to the first hooked bracket and the second hooked bracket, and the inner hook set moving synchronously with the inner rail and interacting with the first hooked bracket in a moving process;
- and
- an outer hook set, installed at a front section of the outer rail, and disposed on a surface configured to be corresponsive to the first hooked bracket and the second hooked bracket, and the outer hook set moving synchronously with the outer rail, and interacting with the first hooked bracket and the second hooked bracket in a moving process;
- such that the inner rail and the middle rail are moved synchronously when the slide rail is pulled out, since the inner hook set is limited by the first hooked bracket, and the middle rail is pulled out with respect to the outer rail until the outer hook set is interacted with the first hooked bracket and the second hooked bracket, and the limit of the first hooked bracket and the second hooked bracket with the inner hook set is released, so that the inner rail can be pulled out with respect to the middle rail;
- on the other hand, when the slide rail is pushed in, the outer rail and the middle rail remain still since the outer hook set is limited by the first hooked bracket and the second hooked bracket, and the inner rail is pushed in with respect to the middle rail until the inner hook set is interacted with the first hooked bracket and the second hooked bracket, and the limit of the first hooked bracket and the second hooked bracket with the outer hook set is released, before the middle rail can be pushed in with respect to the outer rail.
