Problems solved by technology

[0002] At present, the three-section slide rails on the market mainly have the following problems in practical application: First, noise is generated during use: the existing three-section slide rails use the upper rail to run first, and when the upper rail travel distance reaches the extreme, use the upper rail Contact and collide with the limit device of the middle rail, and pull out the middle rail; also use the limit device of the middle rail and the lower rail to contact and collide, to reach the distance that the middle rail is pulled to reach the pole; and the limit device is between the upper rail and the middle rail , The noise of "peddling, pedaling" is generated during the contact and collision between the middle rail and the lower rail, which brings high-frequency noise to the user
[0004] The above two mechanisms to solve the left and right sway both use a connecting rod to fix one of the three slide rails, because the connecting rod may tilt between the two slide rails, so it still cannot completely solve the problem that the left and right symmetrical slide rails have equal pull-out distances. , so that the left and right shaking of the object on a pair of three-section slide rails cannot be eradicated
In practical application, the first mechanism is relatively simple but the effect is not good. The left and right three-section slide rails reserve less space for lifting and shrinking, and there is still obvious left and right shaking, and the connecting rod method is used to adjust the structure of the object that needs to slide on it. There are certain restrictions, and the connecting rod needs to be avoided. At the same time, there is a "peddling" impact sound when the three-section slide rail is running.
The second type of structure is relatively complex and costly, but it uses a rack, gear and connecting rod device, which has great restrictions on the structure of objects that need to slide on it and reduces the effective space for objects between the slide rails. "the sound of

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] see Figure 1 to Figure 4 As shown, the present invention provides a slide rail mechanism 100 for pulling out or pushing a drawer (not shown) in a box, including two sets of slide rail assemblies 1 oppositely arranged so that the two sets of slide rail assemblies 1 are kept in sync Mobile synchronization mechanism 2. Of course, the slide rail mechanism 100 can also be used for drawing, expanding or contracting other structures.

[0022] The slide rail assembly 1 includes a first slide rail assembly 11a and a second slide rail assembly 11b, each slide rail assembly 1 has an upper rail 111, a middle rail 112 and a lower rail 113 that are slidably fitted with each other, that is, the first slide rail assembly 11a has a first upper rail 111a,...

Abstract

The invention provides a slide rail mechanism. The slide rail mechanism comprises first slide rail assemblies and second slide rail assemblies which are arranged oppositely, and a synchronizing mechanism, wherein each slide rail assembly comprises an upper rail, a middle rail and a lower rail which are in sliding fit with one another; the synchronizing mechanism is used for driving the first slide rail assemblies and the second slide rail assemblies to keep moving synchronously; the synchronizing mechanism comprises steering parts, fixing parts and tensioning parts arranged on the two groups of slide rail assemblies; the tensioning parts are wound between the fixing parts of the two groups of slide rail assemblies through the steering parts; the fixing parts comprise upper fixing parts arranged on the two upper rails respectively and lower fixing parts on at least one lower rail; in the opening and closing processes and the opening or closing process of the slide rail assemblies, the upper fixing parts are always positioned between the back ends of the upper rails and the front ends of the middle rails, and the lower fixing parts are always positioned between the front ends of the lower rails and the back ends of the middle rails; during movement of the upper rails or the middle rails of the first slide rail assemblies, the tensioning parts are used for driving the upper rails or the middle rails of the second slide rail assemblies to move towards the same direction by the same distance through the fixing parts.

Description

technical field [0001] The invention relates to a sliding rail mechanism, in particular to a synchronous and silent sliding rail mechanism. Background technique [0002] At present, the three-section slide rails on the market mainly have the following problems in practical application: First, noise is generated during use: the existing three-section slide rails use the upper rail to run first, and when the upper rail travel distance reaches the extreme, use the upper rail Contact and collide with the limit device of the middle rail, and pull out the middle rail; also use the limit device of the middle rail and the lower rail to contact and collide, to reach the distance that the middle rail is pulled to reach the pole; and the limit device is between the upper rail and the middle rail , The noise of "peddling, pedaling" is generated during the contact and collision between the middle rail and the lower rail, which brings high-frequency noise to the user. Secondly, left and ...
