Description

A synchronised slide driven by a single-sided rope

technical field

The utility model specifically relates to a synchronous multi-stage sliding rail, in particular to a synchronous sliding rail driven by a single-side rope.

Background technique

Synchronous slide rail generally refers to a multi-stage slide rail mechanism that includes at least an upper rail, a middle rail and a lower rail. Generally, the upper and lower sides of the middle rail are respectively connected to the upper rail and the lower rail by rolling balls. During use, it is often easy to fall down. The friction force between the rail and the middle rail is large. When the lower rail and the middle rail do not have relative displacement, the upper rail will slide on the middle rail. In this case, especially when the upper rail is closed, it is prone to the problem of the middle rail protruding, such as the upper rail. When the drawer is installed on the drawer and the lower rail is installed on the cabinet body of the drawer, when the drawer is retracted from the fully opened state, the friction between the middle rail and kneeling is large, and when the drawer is closed, the drawer first extends into the cabinet with the upper rail. In the body, the position of the middle rail remains unchanged, but since the upper rail has been retracted, the middle rail is in a state of extending. In this state, during the closing process of the drawer, the retracted upper rail lacks the support of the middle rail, but at this time the drawer is connected to the upper rail. The rail has been retracted, and the gravity of the drawer cannot be uniformly transmitted to the lower rail through the middle rail, which may easily cause the upper rail and the middle rail to be misaligned, or even directly cause the upper rail to be directly separated from the middle rail, or the drawer is closed, but the middle rail still leaks outside the drawer The problem.

Therefore, in response to such problems, we need a synchronous mechanism that can drive the middle rail and the upper rail to synchronously pull out and close and retract. Although there are some synchronous sliding rail mechanisms guided by guide rails and sliders on the market, the structure is complex, resulting in Multiple slide rails are large in size and occupy a large installation space, and due to the guiding effect of the slide rail sliders, certain noise problems are easily generated. And the degree of fit is getting higher and higher. Some slide rail devices with synchronizing mechanisms are equipped with limiters on both sides, resulting in that both sides of the slide rail cannot fit well.

Based on this, we need a multi-stage synchronous slide rail device that can be lower in cost, smaller in installation clearance, and can achieve synchronous pull-out and closed-retraction.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1 to 5. In the embodiment of the present invention, a synchronous slide rail driven by a single side rope includes an upper rail 1, a middle rail 2 and a lower rail 3. The top and bottom of the middle rail 2 are along the middle of the middle rail. The upper rail 1 and the lower rail 3 are slidably clamped in the extending direction of the rail 2. The front side wall or the rear side wall of the middle rail 2 is provided with an annular closed rope 21, and the rope 21 corresponds to The annular plane is parallel to the front side wall or the rear side wall of the middle rail 2, and the upper rail connecting piece 22 and the lower rail connecting piece 23 are respectively fixed on the two rotating ring edges in the opposite direction of the rope 21. The middle rail 2 is connected with the lower rail 3 through the lower rail connecting piece 23 , the middle rail 2 is connected with the upper rail 1 through the upper rail connecting piece 22 , and the middle rail 2 is adjacent to the side of the rope 21 . The left and right sides of the wall are respectively fixed with guide pieces 20 for guiding the rope 21 to rotate along the circle. When the rope 21 rotates, the upper rail connecting piece 22 and the lower rail connecting piece 23 move relative to the middle rail 2 In the opposite direction.

When working, when applied to the drawer scene, in general, the lower rail 3 is fixedly installed on the cabinet body of the drawer, the upper rail 1 is fixedly installed on the drawer body, the middle rail 2 is rollingly connected to the lower rail 3, and the upper rail 1 slides. When the upper rail 1, the middle rail 2 and the lower rail 3 are pulled apart from the storage state, as shown in Figure 1, the upper rail 1 is first pulled apart by force, and the upper rail 1 is in phase with the upper rail connector 22. Connected, the upper rail 1 drives the rope 21 to move through the upper rail connecting piece 22, and the rope 21 rotates as a whole, but here because the lower rail 3 is in a fixed state, the position of the lower rail connecting piece 23 itself connected to the lower rail 3 It is invariable, that is, the length of the rope 21 between the upper rail connector 22 and the lower rail connector 23 cannot be changed, but the position of the upper rail connector 22 and the lower rail connector 23 changes during the pulling process. The rope 21 between the rail connector 23 and the upper rail connector 22 will be pulled 2 to move synchronously with the upper rail connector 22, as shown in FIG. 22. A section of rope 21 in the clockwise direction moves on the middle rail 2, and the actual action effect is that during the pulling process of the upper rail 1, the middle rail 2 and the upper rail 1 slide and open on the lower rail 3 in the same direction. At this time, the upper rail connecting piece The moving direction of 22 relative to the middle rail 2 is consistent with the pulling direction, while the moving direction of the lower rail connector 23 relative to the middle rail 2 is opposite to the pulling direction, that is, the upper rail connecting member 22 and the lower rail connecting member 23 are relative to each other. The middle rail 2 moves in the opposite direction of constraint adjustment. When the upper rail 1 is pulled to the limit position, the middle rail 2 is also pulled to the limit position synchronously. When there is an open state to a closed storage state, the upper rail 1 is connected by the upper rail. 22 drives the rope 21 to move in the opposite direction, the lower rail connecting piece 23 is in a fixed position, and the upper rail connecting piece 22 moves toward the lower rail connecting piece 23, then the lower rail connecting piece 23 to the upper rail connecting piece 22 moves in the same direction.
